Abstract
Seeder cylinder inserted convex suction nozzle, including the roller shaft being arranged on seeder frame, mounting rotary drum on roller shaft, cylinder is equipped with suction nozzle, suction nozzle is shaped with sucker, it is characterised in that described suction nozzle includes the convex shape suction nozzle that nozzle head and suction nozzle seat are constituted, and is shaped with suction kind mouth in nozzle head, being shaped with taper wind inlet and circular inlet scoop in suction nozzle seat, taper sucker, circular inlet scoop and suction kind mouth connect the sucker constituting suction nozzle.This programme uses the design of taper sucker, the interior flow velocity of the suction nozzle of taper sucker design is 2 to 3 times of common suction nozzle, substantially increases the absorption property of suction nozzle, it is to avoid many phenomenons formed due to the irregular of abnormity seed, significantly lower replay rate, it is achieved abnormity seed high speed Precise sowing.
Description
Technical field
The present invention relates to seeder cylinder, particularly relate to the inserted convex suction nozzle of a kind of seeder cylinder, belong to agricultural mechanical field, be particularly well-suited to the absorption of the abnormity seeds such as Fructus Lycopersici esculenti, Fructus Capsici, Fructus Solani melongenae, Fructus Melo.
Background technology
Traditional seeder cylinder, is typically all and directly offers sucker on cylinder wall, and aperture is big, and suction is little, when absorption abnormity seed, hole or many phenomenons easily occurs.Therefore, applicant has developed a kind of entitled " the seeder cylinder of band suction nozzle ", the utility model patent of patent No. CN201220448550.6, be mainly characterized by having suction nozzle, described suction nozzle to exceed the outer wall of cylinder at described cylinder regulating the spleen and stomach, suction nozzle is shaped with suction hole.Its advantage be suction nozzle be a less projection, projection exceeds the outer wall of cylinder, after flat seed is by suction nozzle sorption, just attaching on the suction nozzle head of suction nozzle hole and suction nozzle bore edges, only seed is just held in the center of suction nozzle, if the deviation from center, area because being attached on suction nozzle is little, can automatically drop, so each suction hole only has a seed, avoid wasting seed, reach the purpose that a cave is a kind of.But have the drawback that: described sucker is straight through hole, at seeds such as absorption bigger abnormity seeds, such as Fructus Lycopersici esculenti, Fructus Capsici, Fructus Solani melongenae, Fructus Melo, under conditions of identical negative pressure, same cross-sectional area, in the suction nozzle of linear through hole, flow velocity is not enough, and suction is little, seed is difficult to hold, and causes hole to occur.
Summary of the invention
The invention aims to overcome the shortcoming of prior art, one is provided to use the design of taper sucker, the suction flow velocity around sucker is made to significantly improve, avoid many phenomenons formed due to the irregular of abnormity seed, significantly lower replay rate, it is achieved the seeder cylinder inserted convex suction nozzle of abnormity seed high speed Precise sowing.
The technical scheme of seeder cylinder of the present invention inserted convex suction nozzle is: include the roller shaft being arranged on seeder frame, mounting rotary drum on roller shaft, cylinder is equipped with suction nozzle, suction nozzle is shaped with sucker, it is characterized in that described suction nozzle includes the convex shape suction nozzle that nozzle head and suction nozzle seat are constituted, being shaped with in nozzle head and inhale kind of a mouth, be shaped with taper wind inlet and circular inlet scoop in suction nozzle seat, taper sucker, circular inlet scoop and suction kind mouth connect the sucker constituting suction nozzle.
The seeder cylinder inserted convex suction nozzle of the present invention, suction nozzle profile and sucker shape are improved design, efficiently solve a difficult problem for abnormity planting seed, in identical negative pressure, under conditions of same cross-sectional area, the interior flow velocity of the suction nozzle of taper sucker design is 2 to 3 times of common suction nozzle, substantially increase the absorption property of suction nozzle, so the seed that less aperture absorption is bigger can be used, both avoided and formed adsorb many xenities simultaneously due to the irregular of abnormity seed, reduce replay rate, seeding accuracy can be improved again due to the guarantee of suction, reduce hole rate.When removing unnecessary absorbed seed, the general mode using malleation to blow is processed, when the flat suction nozzle of tradition forms many absorption, owing to some flat seeds are tightly affixed with cylinder surface, airflow direction has the trend that seed presses to cylinder surface, and seed is difficult to be blown off, even and if convex suction nozzle has many adsorption phenomenas, the air-flow that malleation is blown is to blow to unnecessary seed below seed, makes seed be more easy to be blown off, and reduces replay rate.
The seeder cylinder inserted convex suction nozzle of the present invention, described nozzle head and suction nozzle seat are made into integration by copper material, are integrally machined conveniently, reduce assembly process, and copper material is antirust.The diameter of phi 1 of described circular inlet scoop is 35 times of the diameter of phi 2 inhaling kind of mouth, and suction is big, and flow velocity is fast, high adsorption capacity.

Detailed description of the invention
The present invention relates to a kind of seeder cylinder inserted convex suction nozzle, as shown in Fig. 1 Fig. 3, including the roller shaft 1 being arranged on seeder frame, mounting rotary drum 2 on roller shaft 1, cylinder 2 is equipped with suction nozzle, suction nozzle is shaped with sucker, wherein, described suction nozzle includes the convex shape suction nozzle 3 that nozzle head 31 and suction nozzle seat 32 are constituted, nozzle head 31 is shaped with suction kind mouth 33, being shaped with taper wind inlet 34 and circular inlet scoop 35 in suction nozzle seat 32, taper sucker 34, circular inlet scoop 35 and suction kind mouth 33 connect the sucker 4 constituting suction nozzle.This programme improves design to suction nozzle profile and sucker shape, efficiently solve a difficult problem for abnormity planting seed, under conditions of identical negative pressure, same cross-sectional area, the interior flow velocity of the suction nozzle of taper sucker design is 2 to 3 times of common suction nozzle, substantially increase the absorption property of suction nozzle, so the seed that less aperture absorption is bigger can be used, both avoided and formed adsorb many xenities simultaneously due to the irregular of abnormity seed, reduce replay rate, seeding accuracy can be improved due to the guarantee of suction again, reduce hole rate.When removing unnecessary absorbed seed, the general mode using malleation to blow is processed, when the flat suction nozzle of tradition forms many absorption, owing to some flat seeds are tightly affixed with cylinder surface, airflow direction has the trend that seed presses to cylinder surface, and seed is difficult to be blown off, even and if convex suction nozzle has many adsorption phenomenas, the air-flow that malleation is blown is to blow to unnecessary seed below seed, makes seed be more easy to be blown off, and reduces replay rate.Described nozzle head 31 and suction nozzle seat 32 are made into integration by copper material, are made into integration easy to process, reduce assembly process, and copper material is antirust.The diameter of phi 1 of described circular inlet scoop 35 is 35 times of the diameter of phi 2 inhaling kind of mouth 33, and suction is big, and flow velocity is fast, high adsorption capacity.
