Description

  The present invention relates to a scraping mechanism for removing a processed product having a small apparent specific gravity (hereinafter referred to as a light specific gravity product) from mixed processed products on an operating conveyor.

  In the waste processing industry, a processing operation is performed in which the processed materials mixed on the conveyor are separated into reused materials, incineration unnecessary materials, landfilled wastes, and the like.

  Conventionally, the separation of light specific gravity materials such as plastic, paper waste, wood waste, etc. from the mixed processed material on the conveyor is generally performed by using wind power in addition to human power.

  Since the separation by human power is limited in physical strength and energy, it was difficult to maintain a stable separation for a long time, and labor costs were also required.

  There is a limit to the effective removal of light specific gravity from the state in which sand and sand-like substances and light specific gravity are mixed, and there is a limit to the separation by wind power. There was also a tendency to worsen the surrounding work environment, such as winding up things with wind power and generating dust.

  When the mixed processed material is conveyed while being mechanically transshipped, it has been empirically recognized that the light specific gravity tends to intervene in an upper portion near the surface in the mixed processed material.

  In order to perform this separation process continuously and stably, instead of separating human power with limited physical strength and energy, the provision of an efficient mechanism for mechanical separation processing.

  Providing a mechanism that can enjoy the effect of improving the impact on the work environment compared to the impact on the work environment due to air separation.

  An infinite drive belt having a scraping rod that specifically scrapes and separates the light specific gravity in the mixed processed material conveyed on the conveying conveyor that continuously moves, and is provided in a state of crossing the upper portion of the conveying conveyor. A technical concept is provided in which the scraper is continuously brought into contact with the mixed processed product, and the light specific gravity is engaged with the scraper and excluded outside the conveyor.

  An infinite drive belt stretched by a drive roller, a driven roller, and an auxiliary roller that are pivotally supported by a frame, and a flexible scraper having a number of columns suitable for the width of the belt and an adjacent interval. A scraping mechanism consisting of a large number of tacks.

  In a scraping rod having an assembly seat, a flexible portion, and a collar, the flexible portion is positioned at a position in contact with the infinite drive belt, and the couple caused by the scraping rod by the light specific gravity object to be processed is infinite. A support point to be applied to the drive belt is configured, and an assembly seat is provided at an appropriate distance from the support point at a position capable of resisting the couple. In addition, the mounting seat is formed with an appropriate length in the orthogonal direction to resist the acting force in the orthogonal direction due to the displacement in the direction orthogonal to the driving direction of the scraping rod, and is assembled by a plurality of nail rods. A scraper that can be attached.

  By scraping the end of the washer that fastens the assembly seat with a plurality of nail rods and the scraping rod to be returned to the free state into contact with each other, the scraper is assembled to the infinite drive belt in an approximately vertical state. A scraping mechanism characterized by restoring and maintaining the posture position of the heel.

  For the purpose of eliminating the light specific gravity engaged with the scraper by the operation of the scraper, a comb-shaped exclusion rod having a plurality of grooves corresponding to the number of columns of the scraper and its position is provided. A scraping mechanism characterized in that the engagement between the tip of the groove and the scraping scrape in operation is started from a portion closer to the infinite drive belt, and the workpiece is scraped toward the tip of the scraping tack.

  The number of auxiliary rollers to be provided depends on the shape of the upper section of the conveyor and the crossing direction of the scraping mechanism, and in consideration of the situation in which light specific gravity in the mixed processed product on the conveyor is more efficiently removed, Adjust to adjust the tension of the infinite drive belt.

  An infinite drive belt that has many scraping rods that specifically scrape the light specific gravity in the mixed processed material on the conveyor that moves continuously is provided across the conveyor and mechanically processed. Can be separated and removed from the conveyor by engaging a light specific gravity with a scraper. Even light specific gravity objects that are intertwined with high specific gravity in the transported material can be scraped off with the action and action force of the scraping rod against the removal rod, allowing more efficient separation Exclusion is obtained.

  Compared to the removal of light specific gravity by human power, it is a mechanical type, so that stable removal can be achieved continuously for a long time.

  Since the light specific gravity moored to the scraping bar is largely scraped off by providing the comb-shaped exclusion bar, the light specific gravity can be efficiently removed out of the conveyor.

  In the separation method by wind force, fine earth and sand particles other than light specific gravity materials are rolled up together and dust is scattered in the leeward direction. Since it is only considered that dust is generated in the section related to the thickness of the scraper, it can be assumed that the generation of dust is small.

  The circumferential movement trajectory of the infinite driving belt driven by the driving roller and the driven roller can be changed by the auxiliary roller. By setting the position of the auxiliary roller according to the cross-sectional shape of the top surface of the conveyor and the crossing direction of the conveyor and scraper mechanism, it is possible to set the most advantageous and efficient movement path of the scraper.

  Examples of the present invention will be described below with reference to FIGS. 1 and 2.

  In FIG. 1, a driving roller 4 and a driven roller 5 are pivotally supported on the frame 3, and an infinite driving belt 7 is mounted and engaged with the outer diameter portion of the two rollers. .

  The driving roller 4 is operated at a rotational speed that matches the driving speed of the infinite driving belt 7 by a driving motor (not shown).

  Adjustment of the transition direction and tension of the infinite driving belt 7 is performed by adjusting the distance from the driving roller 4 by moving the both ends of the shaft of the driven roller 5 with an adjusting device (not shown).

  The frame 3 is provided with an appropriate number of auxiliary rollers 6 and their positions are determined by adjusting the interval and height. By adjusting the position of the auxiliary roller 6 in accordance with the cross-sectional shape of the upper surface of the conveyor 1 or the crossing direction of the conveyor 1 and the scraping mechanism, the most efficient movement trajectory of the scraper 8 is set.

  On the outer peripheral surface of an infinite driving belt 7 stretched by a driving roller 4, a driven roller 5, and an auxiliary roller 6 that are pivotally supported by the frame 3, a column suitable for the belt width and circumferential length. A number of flexible scraping rods 8 are provided at a number and an adjacent interval to constitute a scraping mechanism.

  A number of scraping rods 8 engaged with the light specific gravity object 2 provided on the moving infinite drive belt 7 are automatically engaged by being engaged with the grooves of the comb-shaped exclusion rod 10 fixed to the frame 3. Can be eliminated.

  The engagement starting point of the scissor rod 10 with the scraper rod 8 is a position that does not contact the attachment portion of the scraper rod 8 and is closer to the infinite drive belt 7, and has a light specific gravity engaged with the scraper rod 8. The object 2 is scraped off and completed at a position where it is automatically scraped toward the tip of the collar 13 of the collar 8. Accordingly, the exclusion rod 10 is formed in a cross-sectional shape that can be automatically excluded along with the movement of the scraping rod 8.

  The scraping bar 8 is formed by a mounting seat 11, a flexible part 12 and a hook part 13.

  The mounting seat 11 is formed to have an appropriate length in a direction perpendicular to the scraping direction in order to cope with the acting force of the scraping rod 8 swinging left and right with respect to the traveling direction, and infinitely driven by the plurality of nail rods 9. It is fixed to the belt 7.

  The flexible portion 12 is a torsion coil spring or the like, and the acting force due to the bending is set to an acting force capable of bending and escaping so that the flange portion 13 does not scrape the light specific gravity object 2 on the conveyor 2 more than necessary. .

  By positioning the flexible portion 12 at an appropriate distance from the mounting seat 11, the couple of light specific gravity 2 is engaged with the flange portion 13, and the couple generated in the scraper rod 8 is infinitely driven with the flexible portion 12. The nail rod 9 that is configured to receive at the contact portion with the belt 7 and that fixes the mounting seat 11 portion to the infinite drive belt 7 is only tensioned in the axial direction. As a result, the load force applied to the ridge 9 is simplified and reduced.

  By supporting and supporting a part of the scraping rod 8 which is going to return to the free state by the restoring action of the flexible portion 12 to one end portion of the washer 14 which fastens the assembly seat 11 portion by a plurality of nail rods 9, The posture position of the scraper 8 attached to the infinite drive belt 7 in an approximately vertical state can be restored and maintained in a normal state.

  Since the flexible portion 12 operates and bends even if a slight acting force is applied in the free state in the free state, the posture position of the scraper 8 and the scraper 8 to be assembled to the infinite drive belt 7 in an approximately vertical state. The shape of the washer 14 is set for the purpose of fixing the scraping rod 8 to the endless drive belt 7 by matching the state displaced to a position where an appropriate couple is generated.
