技术问题technical problem
本发明旨在克服上述现有技术的不足,提供一种风送式投料机,通过将鼓风机和星型卸料阀一体化,达到集成度高、使用灵活、投料均匀的效果。The purpose of the present invention is to overcome the disadvantages of the above-mentioned prior art, and to provide an air-driven feeding machine, which achieves the effects of high integration, flexible use, and uniform feeding by integrating the blower and the star discharge valve.
技术解决方案technical solution
本发明采取的技术方案是,一种风送式投料机,包括箱体、星型叶轮、端盖、卸料电机、鼓风机和送料管,星型叶轮包括转轴和叶片,相邻两片叶片的夹角区域为叶片间隔。箱体从上往下依次设置有相互连通的进料区、卸料区和送料区;进料区呈漏斗状,卸料区和送料区分别呈一大一小的水平设置的柱状;送料区的一端为进风口,另一端为出料口;星型叶轮安装在卸料区;叶片具有水平边和倾斜边,倾斜边远离转轴的一端向右侧倾斜;卸料电机与星型叶轮的转轴一端连接并安装在端盖上;鼓风机的出风管与进风口连接,送料管与出料口连接。The technical solution adopted by the present invention is, an air-driven feeding machine, including a box body, a star-shaped impeller, an end cover, a discharge motor, a blower and a feeding pipe, the star-shaped impeller includes a rotating shaft and blades, and two adjacent blades The angled area is the blade interval. The box body is provided with interconnected feeding area, unloading area and feeding area in sequence from top to bottom; One end is the air inlet, and the other end is the discharge port; the star-shaped impeller is installed in the discharge area; the blade has a horizontal side and an inclined side, and the end of the inclined side away from the rotating shaft is inclined to the right; the rotating shaft of the discharging motor and the star-shaped impeller One end is connected and installed on the end cover; the air outlet pipe of the blower is connected with the air inlet, and the feeding pipe is connected with the discharge port.
本方案的星型叶轮传动方面,取消了联轴器等零部件,将卸料电机直接固定在箱体的端盖上,卸料电机的输出轴和星型叶轮的一端连接,投料机的轴向尺寸大幅度缩短,实现了小型化。进一步,根据星型叶轮转速和扭矩的要求,卸料电机和星型叶轮之间还可以增加减速机。减速机的输入轴和输出轴同轴,一端与卸料电机的输出轴连接,另一端与星型叶轮连接。减速机可选用各类行星减速机。In terms of star-shaped impeller transmission in this scheme, parts such as couplings are canceled, and the unloading motor is directly fixed on the end cover of the box. The output shaft of the unloading motor is connected to one end of the star-shaped impeller, and the shaft of the feeder The size has been greatly shortened to achieve miniaturization. Further, according to the speed and torque requirements of the star-shaped impeller, a reducer can be added between the unloading motor and the star-shaped impeller. The input shaft and output shaft of the reducer are coaxial, one end is connected with the output shaft of the unloading motor, and the other end is connected with the star impeller. Various types of planetary reducers can be selected for the reducer.
本方案中,饲料从进料区的上方进入,从送料区的出料口离开。倾斜边向右倾斜,则左端为进风口,右端为出料口。进风口和出料口一般使用圆形,送料区具有进风口和出料口,为了简化结构,统一设置为圆柱状的管道。星型叶轮的回转轨迹大体为圆柱状,卸料区包裹星型叶轮也大体为圆柱状。星型叶轮左端的倾斜边的回转轨迹为圆锥形,卸料区的左端也为圆锥形。箱体的右侧开孔,星型叶轮从右侧装入卸料区。端盖位于箱体的右侧,端盖的安装面有用于与卸料电机连接的法兰,安装面中心留有卸料电机输出轴或减速机通过的开孔。In this scheme, the feed enters from the top of the feeding area and leaves from the outlet of the feeding area. The inclined side is inclined to the right, then the left end is the air inlet, and the right end is the discharge port. The air inlet and outlet are generally circular, and the feeding area has an air inlet and outlet. In order to simplify the structure, they are uniformly set as cylindrical pipes. The rotation track of the star impeller is generally cylindrical, and the star impeller wrapped in the discharge area is also generally cylindrical. The rotary track of the inclined side at the left end of the star impeller is conical, and the left end of the discharge area is also conical. There is a hole on the right side of the box, and the star impeller is loaded into the discharge area from the right side. The end cover is located on the right side of the box body. The mounting surface of the end cover has a flange for connecting with the unloading motor, and there is an opening for the output shaft of the unloading motor or the reducer to pass through in the center of the mounting surface.
本方案的进料区的上方表面,即箱体的上表面,设置有连接法兰,装有饲料的料仓可以安装在连接法兰上,料仓的下方具有开孔,饲料从开孔由料仓进入箱体的进料区。The upper surface of the feeding area of this scheme, that is, the upper surface of the box body, is provided with a connecting flange, and the feed bin can be installed on the connecting flange. The silo enters the feeding area of the box.
投料机的工作过程如下:饲料从进料区的上方进入,通过进料区和卸料区相通的开口,落入星型叶轮的叶片间隔中。卸料电机通电带动星型叶轮转动至下方。饲料通过卸料区和送料区相通的开口,落入送料区的管内。鼓风机通电后,空气从进风口输入,带动饲料从出料口输出。饲料在风压的作用下,从送料管的末端均匀喷撒。卸料电机持续转动,不停地将落入叶片间隔的饲料送入送料区。鼓风机持续运转,不停地将送料区中的饲料通过送料管均匀喷撒。The working process of the feeding machine is as follows: the feed enters from the top of the feeding area, passes through the opening connecting the feeding area and the discharging area, and falls into the blade interval of the star-shaped impeller. The unloading motor is energized to drive the star-shaped impeller to rotate to the bottom. The feed falls into the tube of the feeding area through the opening that the unloading area communicates with the feeding area. After the blower is powered on, the air is input from the air inlet, and the feed is driven to be output from the outlet. The feed is evenly sprayed from the end of the feeding pipe under the action of wind pressure. The unloading motor rotates continuously to continuously send the feed falling into the blade interval into the feeding area. The blower continues to run, constantly spraying the feed in the feeding area evenly through the feeding pipe.
上述工作过程中,卸料区左端的圆锥形面为叶片间隔中的饲料提供了支撑,使饲料倾斜向右落入送料区。饲料具有向右运动的动能,与送料区中的空气输送方向一致,空气更容易、更均匀地带走饲料,从而使投料更加均匀和避免了饲料容易堆积堵塞的问题。此外,在叶片具有相同长度的情况下,叶片具有的倾斜边能增大与卸料区的接触面积,进而提升卸料装置上、下部气压隔断的效果。During the above working process, the conical surface at the left end of the unloading area provides support for the feed in the blade interval, so that the feed falls into the feeding area obliquely to the right. The feed has the kinetic energy of moving to the right, which is consistent with the air delivery direction in the feeding area, and the air can take away the feed more easily and evenly, thus making the feeding more uniform and avoiding the problem of easy accumulation and blockage of the feed. In addition, when the blades have the same length, the inclined edge of the blade can increase the contact area with the unloading area, thereby improving the effect of air pressure isolation between the upper and lower parts of the unloading device.
本方案的投料机,通过对箱体内腔体的设计,形成进料区、卸料区和送料区三大区域。箱体上集鼓风机与星型卸料阀为一体,形成一种小型化的投料机。改造现有设备时,只需将饲料仓与进料区连接,无需其他配置,即可通过送料管完成各类颗粒饲料投料,达到集成度高、使用灵活、投料均匀的效果。此外,根据饲料投喂的具体要求,送料管的末端可以再进一步外接不同类型的喷嘴,实现不同的投料效果。The feeding machine of this scheme, through the design of the cavity in the box, forms three major areas: the feeding area, the unloading area and the feeding area. The blower and the star discharge valve are integrated on the box body to form a miniaturized feeding machine. When transforming existing equipment, it is only necessary to connect the feed bin to the feeding area without other configurations, and all kinds of pellet feed can be fed through the feeding pipe to achieve the effects of high integration, flexible use, and uniform feeding. In addition, according to the specific requirements of feed feeding, the end of the feeding pipe can be further connected with different types of nozzles to achieve different feeding effects.
优选地,所述送料区和卸料区的轴线方向相同,送料区位于所述卸料区的正下方,所述送料区和卸料区相通的开口为第二开口。若送料区与卸料区的轴线成90°相交设置时,为了保证叶片间隔中的饲料要全部落入送料区,送料区的直径需要大于等于星型叶轮的叶片长度,或者增加类似漏斗的结构。设备整体尺寸将大幅度增大,体型笨重。同时,送料区空间变大,导致风压将迅速下降,难以充分吹走送料区中的饲料。轴线方向相同的限定,只需保证第二开口的长度比星型叶轮的叶片长度长,叶片间隔中的全部饲料就能轻松通过入送料区。送料区的直径可以根据风压进一步确定。此外,从进风口进入的空气沿星型叶轮的轴向运动,不会被叶片过多地阻挡,从而形成扰流,影响气力输送,同时也不会增加星型叶轮的回转阻力。最后,由于叶片间隔中的饲料是靠重力落入送料区的,相比于侧下方的布置,正下方的限定能进一步保证叶片间隔中的饲料全部落入,避免了饲料残留在叶片间隔中又再次回到上方,同时使送料区的管道内能容纳更多的饲料。Preferably, the axis directions of the feeding area and the discharging area are the same, the feeding area is located directly below the discharging area, and the opening connecting the feeding area and the discharging area is the second opening. If the axes of the feed area and the discharge area intersect at 90°, in order to ensure that all the feed in the blade interval falls into the feed area, the diameter of the feed area must be greater than or equal to the blade length of the star-shaped impeller, or a funnel-like structure should be added . The overall size of the equipment will be greatly increased, and the body will be bulky. At the same time, the space in the feeding area becomes larger, causing the wind pressure to drop rapidly, making it difficult to fully blow away the feed in the feeding area. As long as the axial direction is the same, it is only necessary to ensure that the length of the second opening is longer than the blade length of the star-shaped impeller, and all the feed in the blade interval can easily pass into the feeding area. The diameter of the feeding area can be further determined according to the wind pressure. In addition, the air entering from the air inlet moves along the axial direction of the star-shaped impeller, and will not be blocked too much by the blades, thereby forming turbulent flow and affecting the pneumatic delivery, and at the same time, it will not increase the rotational resistance of the star-shaped impeller. Finally, since the feed in the leaf interval falls into the feeding area by gravity, compared with the arrangement at the bottom of the side, the limitation directly below can further ensure that all the feed in the leaf interval falls into it, avoiding the feed remaining in the leaf interval and Go back to the top again, while allowing more feed to be accommodated in the pipes in the feed area.
进一步,第二开口的长度方向两端分别与所述水平边两端对齐;第二开口的宽度等于1个所述叶片间隔对应的宽度。第二开口的长度应大于等于星型叶轮的水平边长度,但过长则又会影响卸料区气压隔断的效果,因此第二开口的长度方向两端恰好与所述水平边两端对齐。宽度的限定,可以保证每次只落入1个叶片间隔的饲料,避免了饲料堆积在送料区。Further, the two ends of the second opening in the length direction are respectively aligned with the two ends of the horizontal side; the width of the second opening is equal to the width corresponding to one blade interval. The length of the second opening should be greater than or equal to the length of the horizontal side of the star-shaped impeller, but if it is too long, it will affect the effect of air pressure isolation in the discharge area. Therefore, the two ends of the second opening in the length direction are just aligned with the two ends of the horizontal side. The limited width can ensure that the feed only falls into one leaf interval each time, avoiding the accumulation of feed in the feeding area.
进一步,所述第二开口向右下方向延伸形成连接通道,连接通道连通所述送料区和卸料区。连接通道上下开口,左右侧面倾斜。倾斜的左侧面与卸料区的左端的圆锥面效果类似,让落入的饲料具有向右运动的动能。更进一步,左侧面的倾斜角度和所述倾斜边的倾斜角度相同,侧面相当于卸料区的左端的圆锥面的延伸。此外,第二开口的右端还可以进一步优化为圆弧形,连接通道的右侧面为曲面。倾斜的圆弧曲面可以为让右下运动的饲料从卸料区平滑过渡到送料区。Further, the second opening extends downward to the right to form a connecting channel, and the connecting channel communicates with the feeding area and the discharging area. The connecting channel is opened up and down, and the left and right sides are inclined. The inclined left side has a similar effect to the conical surface at the left end of the unloading area, giving the falling feed the kinetic energy to move to the right. Furthermore, the inclination angle of the left side is the same as that of the inclined side, and the side is equivalent to the extension of the conical surface at the left end of the discharge area. In addition, the right end of the second opening can be further optimized into a circular arc shape, and the right side of the connecting channel is a curved surface. The inclined arc surface can make the feed moving down the right transition smoothly from the unloading area to the feeding area.
优选地,所述转轴上设置有圆锥部和连接部;圆锥部的侧面与所述叶片的右侧倾斜边连接,连接部内嵌于圆锥部的顶角。叶片均匀地沿转轴的圆周分布,叶片具有左右两侧倾斜边,星型叶轮的横截面呈星型。圆锥部一方面对增加了转轴与叶片的连接面积,进而增加叶片的连接强度。另一方面,圆锥部的表面、卸料区左端的圆锥面和叶片配合,形成一个向右倾斜的通道,进一步避免了饲料容易堆积在叶片间隔中的问题。连接部用于与卸料电机的输出轴连接,卸料电机的输出轴有圆型、方型、花键型等多种型式,连接部进行匹配设计。连接部位于圆锥部的顶角,卸料电机的输出轴可以伸入星型叶轮的内部进行连接,进一步缩短了卸料装置的轴向尺寸。Preferably, the rotating shaft is provided with a conical part and a connecting part; the side surface of the conical part is connected to the right inclined side of the blade, and the connecting part is embedded in the apex of the conical part. The blades are evenly distributed along the circumference of the rotating shaft, the blades have left and right inclined sides, and the cross section of the star-shaped impeller is star-shaped. On the one hand, the conical portion increases the connection area between the rotating shaft and the blade, thereby increasing the connection strength of the blade. On the other hand, the surface of the conical part, the conical surface at the left end of the discharge area cooperates with the vanes to form a channel inclined to the right, which further avoids the problem that feed is easy to accumulate in the space between the vanes. The connecting part is used to connect with the output shaft of the unloading motor. The output shaft of the unloading motor has various types such as round, square, spline, etc., and the connecting part is designed to match. The connecting part is located at the top corner of the conical part, and the output shaft of the unloading motor can extend into the interior of the star-shaped impeller for connection, further shortening the axial dimension of the unloading device.
本方案中,连接通道的左侧面和卸料区的左端的圆锥面平滑衔接,连接通道的右侧面和星型叶轮的圆锥面平滑衔接,连接通道刚好覆盖星型叶轮的叶片的水平边。此时,连接通道的左右侧面、卸料区的左端的圆锥面和星型叶轮的圆锥面将形成一个光滑、无缝衔接的向右倾斜的通道表面,星型叶轮的叶片间隔中的饲料将轻松、无阻挡地向右落入送料区。In this scheme, the conical surface on the left side of the connecting channel and the left end of the discharge area is smoothly connected, the right side of the connecting channel is smoothly connected with the conical surface of the star-shaped impeller, and the connecting channel just covers the horizontal edge of the blade of the star-shaped impeller . At this time, the left and right sides of the connecting channel, the conical surface at the left end of the discharge area and the conical surface of the star-shaped impeller will form a smooth and seamless channel surface inclined to the right, and the feed in the blade interval of the star-shaped impeller will be Drop right into the feed area easily and unobstructed.
进一步,所述转轴上还包括有支撑部和圆环部。支撑部位于转轴的最左端,叶片的左侧倾斜边的左侧。圆环部位于转轴的最右端,圆锥部的右侧。卸料区的中心位置有轴承座,轴承座可为滑动或滚动轴承座。支撑部与轴承座配合连接,对星型叶轮的左端形成左侧支撑。星型叶轮的右端通过连接部与卸料电机的输出轴的连接形成右侧支撑。星型叶轮在卸料区中,两端被支撑,自由旋转。圆环部通过圆锥部的底边向转轴的右侧延伸形成。圆环部对星型叶轮整体进行再一次加固,提高星型叶轮整体的结构强度。此外,圆环部的圆环表面与卸料区的内表面相互配合,提高卸料区的气压隔断效果。进一步,为了简化卸料区的结构,星型叶轮旋转形成的圆轨迹、圆锥部的底边、圆环部和卸料区的直径均相等。Further, the rotating shaft also includes a support portion and a ring portion. The supporting part is located at the leftmost end of the rotating shaft, on the left side of the left inclined side of the blade. The ring part is located at the rightmost end of the rotating shaft and the right side of the cone part. There is a bearing seat in the center of the unloading area, which can be a sliding or rolling bearing seat. The support part is matched with the bearing seat to form a left support for the left end of the star-shaped impeller. The right end of the star-shaped impeller is connected to the output shaft of the unloading motor through the connecting part to form a right side support. The star-shaped impeller is supported at both ends in the discharge area and rotates freely. The ring portion is formed by extending the bottom edge of the cone portion to the right side of the rotating shaft. The ring portion reinforces the star-shaped impeller as a whole to improve the structural strength of the star-shaped impeller as a whole. In addition, the ring surface of the ring portion cooperates with the inner surface of the unloading area to improve the air pressure isolation effect of the unloading area. Further, in order to simplify the structure of the discharge area, the diameters of the circular trajectory formed by the rotation of the star-shaped impeller, the bottom edge of the cone, the ring portion and the discharge area are all equal.

Feed falls into the space between the blades of the star-shaped impeller, and the contact between the left inclined edge of the blade and the left end of the discharge area will generate a force to the right, causing the star-shaped impeller to slide to the right, resulting in poor air pressure partition effect. The elastic member is located inside the connecting part, the left side is against the inside of the rotating shaft, and the right side is against the output shaft of the unloading motor. The axial position of the star-shaped impeller is fixed by the pre-tightening force generated by the elastic member to prevent it from sliding to the right.

When a piece of metal passes the sensor, the sensor outputs a signal. The number of rotations of the star impeller is calculated by statistical signal.

Including the rotating shaft 30 and the blades 22 , the angular area between two adjacent blades 22 is the blade interval 23 . The box body 10 is provided with a feed area 11, a discharge area 12 and a feed area 13 which are connected to each other in order from top to bottom; Horizontally arranged columnar shape; one end of the feed area 13 is the air inlet 14, and the other end is the discharge port 15; the star impeller 20 is installed in the discharge area 12; the blade 22 has a horizontal edge 24 and an inclined edge 25, and the inclined edge 25 is far away from the rotating shaft One end of 30 is inclined to the right side; unloading motor 50 is connected with one end of star impeller 20 and is installed on the end cover 40;
本实施例的星型叶轮传动方面,取消了联轴器等零部件,将卸料电机50直接固定在箱体10的端盖40上,卸料电机50的输出轴51和星型叶轮20的一端连接,投料机的轴向尺寸大幅度缩短,实现了小型化。进一步,卸料电机50由电机52和减速机53组成,减速机的输入轴和输出轴同轴,一端与电机52的输出轴连接,另一端与星型叶轮20连接。In terms of star impeller transmission in this embodiment, parts such as couplings are canceled, and the discharge motor 50 is directly fixed on the end cover 40 of the box body 10. The output shaft 51 of the discharge motor 50 and the star impeller 20 Connected at one end, the axial dimension of the feeder is greatly shortened, realizing miniaturization. Further, the unloading motor 50 is composed of a motor 52 and a reducer 53 , the input shaft and output shaft of the reducer are coaxial, one end is connected with the output shaft of the motor 52 , and the other end is connected with the star impeller 20 .
本实施例中,饲料从进料区11的上方进入,从送料区13的出料口15离开。倾斜边25向右倾斜,则左端为进风口14,右端为出料口15。进风口14和出料口15一般使用圆形,送料区13具有进风口14和出料口15,为了简化结构,统一设置为圆柱状的管道。星型叶轮20的回转轨迹大体为圆柱状,卸料区12包裹星型叶轮20也大体为圆柱状。星型叶轮20左端的倾斜边25的回转轨迹为圆锥形,卸料区12的左端也为圆锥形。箱体10的右侧开孔,星型叶轮20从右侧装入卸料区12。端盖40位于箱体10的右侧,端盖的安装面有用于与卸料电机50连接的法兰,安装面中心留有卸料电机50通过的开孔。箱体10外形方正,每条棱边都加粗进行强度加强。In this embodiment, the feed enters from above the feeding area 11 and leaves from the outlet 15 of the feeding area 13 . The inclined side 25 is inclined to the right, then the left end is the air inlet 14, and the right end is the discharge opening 15. The air inlet 14 and the material outlet 15 are generally circular. The feeding area 13 has the air inlet 14 and the material outlet 15. In order to simplify the structure, they are uniformly arranged as cylindrical pipes. The rotation trajectory of the star impeller 20 is generally cylindrical, and the discharge area 12 wrapped around the star impeller 20 is also generally cylindrical. The rotary track of the inclined edge 25 at the left end of the star impeller 20 is conical, and the left end of the discharge area 12 is also conical. The right side of the casing 10 has a hole, and the star impeller 20 is loaded into the discharge area 12 from the right side. The end cover 40 is positioned at the right side of the casing 10, and the mounting surface of the end cover has a flange for connecting with the unloading motor 50, and an opening through which the unloading motor 50 passes is left in the center of the mounting surface. The box body 10 has a square shape, and each edge is thickened for strength strengthening.
卸料区12左端的圆锥形面为叶片间隔23中的饲料提供了支撑,使饲料倾斜向右落入送料区13。饲料具有向右运动的动能,与送料区13中的空气输送方向一致,空气更容易、更均匀地带走饲料,从而使投料更加均匀和避免了饲料容易堆积堵塞的问题。此外,在叶片具有相同长度的情况下,叶片22具有的倾斜边25能增大与卸料区12的接触面积,进而提升卸料装置上、下部气压隔断的效果。The conical surface at the left end of the discharge area 12 provides support for the feed in the blade space 23, so that the feed falls into the feed area 13 obliquely to the right. The feed has the kinetic energy of moving to the right, which is consistent with the air delivery direction in the feeding area 13, and the air can take away the feed more easily and more evenly, thereby making feeding more uniform and avoiding the problem that the feed is easy to accumulate and block. In addition, when the blades have the same length, the inclined edge 25 of the blade 22 can increase the contact area with the discharge area 12, thereby improving the effect of air pressure isolation between the upper and lower parts of the discharge device.
本实施例的投料机,通过对箱体10内腔体的设计,形成进料区11、卸料区12和送料区13三大区域。箱体10上集鼓风机60与星型卸料阀为一体,形成一种小型化的投料机。改造现有设备时,只需将饲料仓与进料区11连接,无需其他配置,即可通过送料管80完成各类颗粒饲料投料,达到集成度高、使用灵活、投料均匀的效果。The feeding machine of this embodiment, through the design of the inner cavity of the box body 10 , forms three major areas: the feeding area 11 , the unloading area 12 and the feeding area 13 . The blower 60 and the star discharge valve are integrated on the box body 10 to form a miniaturized feeding machine. When transforming existing equipment, it is only necessary to connect the feed bin to the feeding area 11 without other configurations, and various pellet feeds can be fed through the feeding pipe 80 to achieve the effects of high integration, flexible use, and uniform feeding.
优选地,所述送料区13和卸料区12的轴线方向相同,送料区13位于所述卸料区12的正下方,所述送料区13和卸料区12相通的开口为第二开口18。轴线方向相同的限定,只需保证第二开口18的长度比星型叶轮20的叶片22长度长,叶片间隔23中的全部饲料就能轻松通过入送料区13。送料区13的直径可以根据风压进一步确定。此外,从进风口14进入的空气沿星型叶轮20的轴向运动,不会被叶片22过多地阻挡,从而形成扰流,影响气力输送,同时也不会增加星型叶轮20的回转阻力。最后,由于叶片间隔23中的饲料是靠重力落入送料区13的,相比于侧下方的布置,正下方的限定能进一步保证叶片间隔中的饲料全部落入,避免了饲料残留在叶片间隔23中又再次回到上方,同时使送料区13的管道内能容纳更多的饲料。Preferably, the axial directions of the feeding area 13 and the discharging area 12 are the same, the feeding area 13 is located directly below the discharging area 12, and the opening that the feeding area 13 communicates with the discharging area 12 is the second opening 18 . As long as the axial direction is the same, it is only necessary to ensure that the length of the second opening 18 is longer than the length of the blades 22 of the star-shaped impeller 20 , so that all the feed in the blade interval 23 can easily pass into the feeding area 13 . The diameter of the feeding zone 13 can be further determined according to the wind pressure. In addition, the air entering from the air inlet 14 moves along the axial direction of the star-shaped impeller 20, and will not be blocked too much by the blades 22, thereby forming turbulent flow and affecting the pneumatic conveying, and at the same time, the rotation resistance of the star-shaped impeller 20 will not be increased. . Finally, since the feed in the blade interval 23 falls into the feeding area 13 by gravity, compared with the arrangement under the side, the limitation directly below can further ensure that all the feed in the blade interval falls in, avoiding the feed remaining in the blade interval 23 and get back to the top again, while making it possible to accommodate more feed in the pipeline of the feeding area 13.
进一步,第二开口18的长度方向两端分别与所述水平边24两端对齐;第二开口18的宽度等于1个所述叶片间隔23对应的宽度。第二开口18的长度应大于等于星型叶轮20的水平边24长度,但过长则又会影响卸料区12气压隔断的效果,因此第二开口18的长度方向两端恰好与所述水平边24两端对齐。宽度的限定,可以保证每次只落入1个叶片间隔23的饲料,避免了饲料堆积在送料区13。Further, the two ends of the second opening 18 in the length direction are respectively aligned with the two ends of the horizontal side 24 ; the width of the second opening 18 is equal to the width corresponding to one blade interval 23 . The length of the second opening 18 should be greater than or equal to the length of the horizontal side 24 of the star impeller 20, but if it is too long, it will affect the effect of the air pressure partition of the discharge area 12, so the two ends of the second opening 18 in the length direction are just in line with the horizontal Edges 24 are justified. The limitation of the width can ensure that the feed that only falls into one blade interval 23 at a time avoids the accumulation of feed in the feeding area 13 .
进一步,所述第二开口18向右下方向延伸形成连接通道16,连接通道16连通所述送料区13和卸料区12。连接通道16上下开口,左右侧面倾斜。倾斜的左侧面与卸料区12的左端的圆锥面效果类似,让落入的饲料具有向右运动的动能。更进一步,左侧面的倾斜角度和所述倾斜边25的倾斜角度相同,侧面相当于卸料区12的左端的圆锥面的延伸。此外,第二开口18的右端进一步优化为圆弧形,连接通道16的右侧面为曲面。倾斜的圆弧曲面可以为让右下运动的饲料从卸料区12平滑过渡到送料区13。Further, the second opening 18 extends downward to the right to form a connecting channel 16 , and the connecting channel 16 communicates with the feeding area 13 and the discharging area 12 . The connecting channel 16 is opened up and down, and the left and right sides are inclined. The effect of the inclined left side is similar to that of the conical surface at the left end of the unloading area 12, allowing the falling feed to have the kinetic energy of moving to the right. Furthermore, the inclination angle of the left side is the same as that of the inclined side 25 , and the side is equivalent to the extension of the conical surface at the left end of the discharge area 12 . In addition, the right end of the second opening 18 is further optimized to be arc-shaped, and the right side of the connecting channel 16 is a curved surface. The inclined arc surface can be used to make the right-down moving feed smoothly transition from the unloading area 12 to the feeding area 13 .
如图2、5所示,优选地,所述转轴30上设置有圆锥部32和连接部33;圆锥部32的侧面与所述叶片22的右侧倾斜边25连接,连接部33内嵌于圆锥部32的顶角。转轴30为空心转轴。叶片22均匀地沿转轴30的圆周分布,叶片22具有左右两侧倾斜边25,星型叶轮20的横截面呈星型。星型叶轮20的叶片数量为9片,叶片22的形状为平行四边形,叶片22的倾斜角度为30°-60°。圆锥部32一方面对增加了转轴30与叶片22的连接面积,进而增加叶片22的连接强度。另一方面,圆锥部32的表面、卸料区12左端的圆锥面和叶片22配合,形成一个向右倾斜的通道,进一步避免了饲料容易堆积在叶片间隔23中的问题。连接部33位于圆锥部32的顶角,卸料电机50的输出轴51可以伸入星型叶轮20的内部进行连接,进一步缩短了卸料装置的轴向尺寸。As shown in Figures 2 and 5, preferably, the rotating shaft 30 is provided with a conical portion 32 and a connecting portion 33; the side of the conical portion 32 is connected to the right inclined side 25 of the blade 22, and the connecting portion 33 is embedded in The apex angle of the conical portion 32 . The rotating shaft 30 is a hollow rotating shaft. The blades 22 are evenly distributed along the circumference of the rotating shaft 30 , the blades 22 have left and right inclined sides 25 , and the cross section of the star impeller 20 is star-shaped.
