Description

Technical Field

[0001] This invention relates to the field of fertilizer processing technology, specifically to a feeding buffer device for a fertilizer production line. Background Technology

[0002] The feeding device is a key component in a fertilizer production line, used to accurately input various raw materials into the production equipment. Depending on the production process, different feeding methods can be used, such as screw feeding or vibrating feeding, to ensure the stability and accuracy of material conveying and improve overall production efficiency.

[0003] Chinese Patent Publication No. CN116675029A discloses a dust-free feeding device for solid fertilizer, applied in the field of solid fertilizer feeding technology. This invention, by setting up a dust removal component, can remove dust generated by solid fertilizer entering the feeding cylinder. The exhaust fan creates a negative pressure state inside the absorption box, causing the dust to enter the absorption box and be intercepted by a screen. Simultaneously, under the action of a pushing component, the screen vibrates, shaking off the dust adhering to it and discharging it from the absorption box, thus completing the dust removal work and preventing dust from spreading into the environment. By setting up an intermittent feeding component, the solid fertilizer entering the feeding cylinder can be fed intermittently, avoiding the possibility of pipe blockage when the feeding amount is too large, ensuring the normal operation of solid fertilizer feeding.

[0004] However, the current feeding device has the following problems: when the feeding device is used to mix fertilizer, the material is fed directly, so the fertilizer is fed in at a relatively fast speed. The rapid feeding will cause fertilizer to accumulate, which will affect the mixing and processing of the equipment. Therefore, we propose a feeding buffer device for fertilizer production line. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a feeding buffer device for fertilizer production lines, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a feeding buffer device for a fertilizer production line, comprising a frame, a material tank being fixed through and fixed to the top of the frame, a spiral feeding assembly being fixed to the bottom of the material tank, a negative pressure dust collector being fixed to the top of the material tank, a feeding assembly being provided on the side of the material tank, the feeding assembly comprising a housing, the housing being fixed to the inlet of the material tank, a cutting blade assembly being provided in the middle of the housing, a conveyor belt assembly being provided below the inner wall of the housing, a cover plate being hinged to the side of the housing away from the material tank, a buffer assembly being provided inside the material tank, the buffer assembly comprising a filter cylinder and a drive motor, the filter cylinder being laterally rotatably installed inside the material tank, and the filter cylinder being... A belt ring is fixed to the top of the tank, and a pulley is fixed to the output end of the drive motor. The pulley and belt ring are connected by a belt drive. The drive motor drives the pulley to rotate, which in turn drives the belt ring to rotate. The belt ring drives the filter cylinder to rotate, thus causing the filter cylinder to rotate and feed fertilizer into the tank. Then, the screw feeding assembly is activated, which feeds the fertilizer into the production equipment, thus realizing the fertilizer feeding operation. Several actuating plates are evenly and equidistantly fixed on the inner wall of the filter cylinder. The actuating plates are inclined in a decreasing direction towards the belt ring. At the same time, the filter cylinder drives the actuating plates to rotate, and the actuating plates can continuously actuate the fertilizer bag during the rotation.

[0007] According to the above technical solution, a bag removal device is provided at the material tank. The bag removal device includes a circular shell fixed on the side of the material tank away from the feeding component, and two L-shaped frames horizontally fixed on the inner wall of the material tank. The circular shell penetrates the material tank and the filter cylinder, and a discharge port is opened at the bottom of the side of the circular shell away from the material tank. A drive roller is rotatably installed on the inner wall of the circular shell. The drive roller is driven by a motor. A driven roller one and a driven roller two are rotatably installed between the two L-shaped frames from top to bottom. A sliding groove is opened on the side of each L-shaped frame near the filter cylinder. A slider is slidably installed inside the sliding groove of each L-shaped frame. A spring is provided between the two sliders and the inner wall of the sliding groove of the L-shaped frame. An I-shaped... The roller is connected to the drive roller, driven roller one, and driven roller two by a transmission belt. The bottom of the transmission belt passes over the top of the I-shaped roller. Several oblique spurs are evenly and equidistantly fixed on the outside of the transmission belt. A through-slot plate is fixed at the bottom of the discharge port of the round shell. Several through slots for the oblique spurs to pass through are opened on the top of the through-slot plate. The operator drives the drive roller to rotate by a motor. Under the coordinated action of the drive roller and driven roller one and driven roller two, the drive roller and driven roller one and driven roller two will drive the transmission belt to rotate. The transmission belt drives the oblique spurs to rotate. When the oblique spurs touch the fertilizer bag during rotation, the oblique spurs will hook the fertilizer bag. The fertilizer bag will move with the oblique spurs until the oblique spurs pull the fertilizer bag to the through-slot plate.

[0008] According to the above technical solution, several fixing plates are evenly fixed on the middle circumference of the I-shaped roller. The I-shaped roller drives the fixing plates to rotate. During the rotation, the fixing plates will actively move the fertilizer bag hooked by the inclined barb towards the inclined barb.

[0009] According to the above technical solution, the bag removal device further includes an elliptical groove plate, two elastic telescopic rods, and two trapezoidal plates. The elliptical groove plate is fixed to the outer wall of the drive roller's shaft. An elliptical groove is formed on the outer wall of the elliptical groove plate. The two elastic telescopic rods are slidably installed on both sides of the through groove plate. A connecting plate is fixed between the telescopic ends of the two elastic telescopic rods on the side away from the material tank. A sliding column is fixed to the outer wall of one side of the elastic telescopic rod. The sliding column is slidably installed inside the elliptical groove of the elliptical groove plate. A number of spikes are evenly and equidistantly fixed on the side of the connecting plate near the through groove plate, and the spikes pass through a number of through grooves of the through groove plate. The two trapezoidal plates are respectively fixed on the two sides of the channel plate away from the material tank. The top of the trapezoidal plate is set with an inclined surface. The inclined surface of the trapezoidal plate is located on the movement trajectory of the connecting plate. There is a five-centimeter gap between the trapezoidal plate and the connecting plate. Each time the inclined plate moves the fertilizer bag to the position of the channel plate, the spikes will insert into the fertilizer bag. Each time the spikes move downward, they will pull the fertilizer bag downward. At the same time, when the connecting plate moves downward and reaches the position of the trapezoidal plate, the trapezoidal plate will push the connecting plate to move away from the channel plate. The connecting plate drives the extension end of the elastic telescopic rod to stretch, and the connecting plate moves along with the spikes.

[0010] According to the above technical solution, an anti-stacking device is provided at the L-shaped frame. The anti-stacking device includes two turntables and two track plates. The two turntables are respectively fixed on both sides of the shaft of the driven roller. A fixed column is fixed at the eccentric position on the side of the two turntables that are far apart from each other. The two track plates are respectively fixed on the side of the two L-shaped frames that are far apart from each other. A U-shaped plate is slidably installed on the side of the two track plates that are far apart from each other. The fixed column is slidably installed inside the U-shaped plate. An L-shaped rod is fixed at the bottom of the two U-shaped plates. A semi-circular plate is fixed between the bottoms of the two L-shaped rods. When the driven roller rotates, it will drive the turntable to rotate. The turntable will drive the fixed column to rotate. The fixed column will slide along the inside of the U-shaped plate and push the U-shaped plate to move back and forth along the outer wall of the track plate. The U-shaped plate drives the semi-circular plate to move back and forth through the L-shaped rod. The semi-circular plate pushes the fertilizer bag piled up on one side of the filter cylinder toward the inclined bar plate.

[0011] According to the above technical solution, the anti-overcrowding device further includes two vertical rods and two arc-shaped plates. The two vertical rods are respectively fixed to the tops of two sliders, and a push column is fixed between the tops of the two vertical rods. The two arc-shaped plates are respectively fixed to the tops of two U-shaped plates. Several semi-arc blocks are evenly and equidistantly fixed to the top of the arc-shaped plates. The push column is located on the movement trajectory of the semi-arc blocks of the arc-shaped plates. During the reciprocating movement of the U-shaped plates, the U-shaped plates drive the arc-shaped plates to move accordingly. The semi-arc blocks of the arc-shaped plates push the bottom of the push column, causing the push column to move upward. The push column drives the I-shaped roller to move upward through the slider. When the semi-arc blocks of the arc-shaped plates no longer push the bottom of the push column, the slider is reset by the corresponding spring. The slider drives the I-shaped roller to reset and move downward. This process repeats, thereby causing the I-shaped roller to push the transmission belt to sway up and down.

[0012] This invention provides a feeding buffer device for a fertilizer production line. It has the following beneficial effects:

[0013] (1) By setting up a buffer component, the rotation design of the filter cylinder can buffer the speed during the fertilizer feeding process, which can effectively prevent the fertilizer from clogging during the feeding process, ensure that the fertilizer can smoothly enter the screw feeding component, improve the continuity and reliability of feeding, and at the same time, the rotation of the filter cylinder can prevent the fertilizer from clumping in the tank due to static conditions, maintain the fluidity of the fertilizer. Meanwhile, the filter cylinder drives the actuating plate to rotate, and the actuating plate can continuously actuate the fertilizer bag during the rotation process, so that all the fertilizer in the fertilizer bag can fall out of the fertilizer bag. Furthermore, the inclined surface of the actuating plate will continuously actuate the fertilizer bag towards the filter cylinder away from the feed inlet of the tank during the rotation process, thereby preventing the fertilizer bag in the filter cylinder from affecting the feeding of the next bag of fertilizer.

[0014] (2) The present invention, through the setting of the bag removal device, enables the driving roller, driven roller one, driven roller two, and transmission belt to drive the inclined barb to hook the fertilizer bag. The fertilizer bag will move with the inclined barb until the inclined barb pulls the fertilizer bag to the through groove plate. The through groove plate will intercept the fertilizer bag hooked by the inclined barb at the through groove plate, thereby preventing the inclined barb from bringing the fertilizer bag back into the filter cylinder. At this time, the fertilizer bag can be discharged from the discharge port of the round shell, thereby achieving the purpose of discharging the fertilizer bag inside the filter cylinder, thereby reducing the impact of the fertilizer bag on the discharge of the filter cylinder. At the same time, the driving roller, elliptical groove plate, sliding column, elastic telescopic rod, through groove plate, and connecting plate work together to drive the spikes to pull the fertilizer bag downward, thereby facilitating the separation of the fertilizer bag from the inclined barb. At the same time, the connecting plate, trapezoidal plate, connecting plate, and elastic telescopic rod work together to drive the spikes to move downward a certain distance and then separate from the fertilizer bag, thereby ensuring that the fertilizer bag can effectively fall at the discharge port of the round shell.

[0015] (3) By setting up an anti-stamping device, the driven roller and turntable rotate, and the turntable, fixed column, U-shaped plate, track plate and L-shaped rod cooperate to make the reciprocating motion of the semi-circular plate accurately push the fertilizer bag to the hooking area of ​​the inclined bar plate, ensuring that the fertilizer bag can accurately enter the effective contact range of the inclined bar plate and reduce the failure to hook due to position deviation; at the same time, the U-shaped plate, arc block plate, push column, slider and I-shaped roller cooperate to push the transmission belt to shake up and down, and the transmission belt drives the fertilizer bag hooked by the inclined bar plate to shake through the inclined bar plate, and the fertilizer bag will shake off the fertilizer adhering to it, thereby reducing the amount of fertilizer loss during the process of the fertilizer bag hooked by the inclined bar plate being removed from the filter cylinder.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] Please see Figure 1 - Figure 10One embodiment of the present invention is as follows: a feeding buffer device for a fertilizer production line, comprising a frame 1, a material tank 2 through and fixed to the top of the frame 1, a spiral feeding assembly 3 fixed to the bottom of the material tank 2, a negative pressure dust collector 4 fixed to the top of the material tank 2, a feeding assembly 5 provided on the side of the material tank 2, the feeding assembly 5 including a housing 51, the housing 51 fixed at the inlet of the material tank 2, a cutting blade assembly 52 provided in the middle of the housing 51, a conveyor belt assembly 53 provided below the inner wall of the housing 51, a cover plate 54 hinged to the side of the housing 51 away from the material tank 2, a buffer assembly 6 provided inside the material tank 2, the buffer assembly 6 including a filter cylinder 61 and a drive motor 64, the filter cylinder 61 being laterally rotatably installed inside the material tank 2, a belt ring 62 fixed to the outside of the filter cylinder 61, the drive motor 64 being fixed to the top of the material tank 2, and a pulley 63 fixed to the output end of the drive motor 64. The pulley 63 and belt ring 62 are connected by belt drive. The above structure allows the rotation of the filter cylinder 61 to buffer the speed during fertilizer dispensing, effectively preventing fertilizer blockage and ensuring that the fertilizer can smoothly enter the screw feeding assembly 3, improving the continuity and reliability of feeding. At the same time, the rotation of the filter cylinder 61 can prevent fertilizer from clumping in the tank 2 due to static conditions, maintaining the fluidity of the fertilizer. Several actuating plates 65 are evenly and equidistantly fixed on the inner wall of the filter cylinder 61. The actuating plates 65 are inclined in a decreasing direction towards the belt ring 62. With the above structure, the inclined surface of the actuating plates 65 continuously pushes the fertilizer bag away from the feed inlet of the tank 2 during rotation, thereby preventing the fertilizer bag in the filter cylinder 61 from affecting the dispensing of the next bag of fertilizer.

[0029] A bag removal device 7 is installed at the material tank 2. The bag removal device 7 includes a circular shell 71 fixed on the side of the material tank 2 away from the feeding component 5, and two L-shaped frames 77 horizontally fixed on the inner wall of the material tank 2. The circular shell 71 penetrates the material tank 2 and the filter screen cylinder 61, and a discharge port is opened at the bottom of the side of the circular shell 71 away from the material tank 2. A drive roller 72 is rotatably installed on the inner wall of the circular shell 71. The drive roller 72 is driven by a motor. A driven roller 1 73 and a driven roller 2 74 are rotatably installed between the two L-shaped frames 77 from top to bottom. A sliding groove is opened on the side of the two L-shaped frames 77 near the filter screen cylinder 61. A slider 781 is slidably installed inside the sliding groove of the two L-shaped frames 77. A spring is provided between the two sliders 781 and the inner wall of the sliding groove of the L-shaped frame 77. An I-shaped roller 78 is rotatably installed between the two sliders 781. A transmission belt 75 is connected between the drive roller 72, the driven roller 1 73, and the driven roller 2 74. The bottom of the transmission belt 75 passes over the top of the I-shaped roller 78. Several oblique spurs 76 are evenly and equidistantly fixed on the outside of the transmission belt 75. A through-slot plate 79 is fixed at the bottom of the discharge port of the circular shell 71. Several through slots for the oblique spurs 76 to pass through are opened on the top of the through-slot plate 79. With the above structure, when the oblique spurs 76 touch the fertilizer bag during rotation, the oblique spurs 76 will hook the fertilizer bag. The fertilizer bag will move with the oblique spurs 76 until the oblique spurs 76 pulls the fertilizer bag to the through-slot plate 79. The through-slot plate 79 will intercept the fertilizer bag hooked by the oblique spurs 76 at the through-slot plate 79, thereby preventing the oblique spurs 76 from bringing the fertilizer bag back into the filter cylinder 61. At this time, the fertilizer bag can be discharged from the discharge port of the circular shell 71, thereby achieving the purpose of discharging the fertilizer bag inside the filter cylinder 61 and reducing the impact of the fertilizer bag on the discharge of the filter cylinder 61.

[0030] Several fixing plates 782 are evenly fixed around the middle circumference of the I-shaped roller 78. Through the above structure, the I-shaped roller 78 drives the fixing plates 782 to actively move the fertilizer bag hooked by the inclined bar 76 towards the inclined bar 76 during rotation. This helps to enhance the contact force between the fertilizer bag and the inclined bar 76, ensuring that the fertilizer bag can be firmly hooked and preventing the fertilizer bag from slipping or falling off during movement.

[0031] The bag removal device 7 also includes an elliptical groove plate 710, two elastic telescopic rods 711, and two trapezoidal plates 714. The elliptical groove plate 710 is fixed to the outer wall of the shaft of the drive roller 72. An elliptical groove is formed on the outer wall of the elliptical groove plate 710. The two elastic telescopic rods 711 are slidably installed on both sides of the through groove plate 79. A connecting plate 712 is fixed between the telescopic ends of the two elastic telescopic rods 711 away from the material tank 2. A sliding column 715 is fixed to the outer wall of one elastic telescopic rod 711. The sliding column 715 is slidably installed inside the elliptical groove of the elliptical groove plate 710. A number of spikes 713 are evenly and equidistantly fixed on the side of the connecting plate 712 near the through groove plate 79, and the number of spikes 713 respectively pass through the through groove plate 79. A through-slot is formed, and two trapezoidal plates 714 are fixed on the two sides of the through-slot plate 79 away from the material tank 2. The top of the trapezoidal plate 714 is set with an inclined surface. The inclined surface of the trapezoidal plate 714 is located on the movement trajectory of the connecting plate 712. A five-centimeter gap is left between the trapezoidal plate 714 and the connecting plate 712. Each time the inclined bar 76 moves the fertilizer bag to the position of the through-slot plate 79, the above structure will cause the spikes 713 to pull the fertilizer bag downward, thereby facilitating the separation of the fertilizer bag from the inclined bar 76. At the same time, the above structure will cause the connecting plate 712 to move downward with the spikes 713 for a certain distance before separating from the fertilizer bag, thereby ensuring that the fertilizer bag can effectively fall at the discharge port of the round shell 71.

[0032] In use, open the cover 54 and drop the bagged fertilizer onto the conveyor belt assembly 53. Start the conveyor belt assembly 53, which first transports the bagged fertilizer to the cutting blade assembly 52, where it cuts the fertilizer bag. Then, the conveyor belt assembly 53 transports the fertilizer into the filter cylinder 61. The drive motor 64 drives the pulley 63 to rotate, which in turn drives the belt ring 62 to rotate. The belt ring 62 then drives the filter cylinder 61 to rotate, thus causing the filter cylinder 61 to rotate and feed the fertilizer into the material tank 2. After that, start the screw feeding assembly 3, which feeds the fertilizer into the production equipment, thus realizing the fertilizer feeding operation. The rotating design of the filter cylinder 61 can buffer the fertilizer feeding. The speed during the feeding process can effectively prevent fertilizer blockage and ensure that the fertilizer can smoothly enter the screw feeding component 3, improving the continuity and reliability of feeding. At the same time, the rotation of the filter cylinder 61 can prevent fertilizer from clumping in the tank 2 due to static conditions, maintaining the fluidity of the fertilizer. Meanwhile, the filter cylinder 61 drives the agitator plate 65 to rotate. During the rotation, the agitator plate 65 can continuously agitate the fertilizer bag, so that all the fertilizer in the fertilizer bag can fall out of the fertilizer bag. Furthermore, the inclined surface of the agitator plate 65 will continuously agitate the fertilizer bag towards the filter cylinder 61 away from the feed inlet of the tank 2 during the rotation, thereby preventing the fertilizer bag in the filter cylinder 61 from affecting the feeding of the next bag of fertilizer.

[0033] The operator drives the drive roller 72 to rotate via a motor. Under the coordinated action of the drive roller 72, driven roller 1 73, and driven roller 2 74, the drive roller 72, driven roller 1 73, and driven roller 2 74 drive the transmission belt 75 to rotate. The transmission belt 75 drives the inclined spiking plate 76 to rotate. When the inclined spiking plate 76 touches the fertilizer bag during its rotation, the inclined spiking plate 76 hooks the fertilizer bag, and the fertilizer bag moves with the inclined spiking plate 76 until the inclined spiking plate 76 displaces the fertilizer. When the bag is pulled to the channel plate 79, the channel plate 79 will intercept the fertilizer bag hooked by the inclined bar 76 at the channel plate 79, thereby preventing the inclined bar 76 from bringing the fertilizer bag back into the filter cylinder 61. At this time, the fertilizer bag can be discharged from the discharge port of the round shell 71, thereby achieving the purpose of discharging the fertilizer bag inside the filter cylinder 61, thus reducing the impact of the fertilizer bag on the discharge of the filter cylinder 61, while the inclined bar 76 will pass through the channel plate 79.

[0034] It should be noted that the hollow design of the I-shaped roller 78 prevents it from interfering with the operation of the inclined spur plate 76. Furthermore, during the rotation of the transmission belt 75, the transmission belt 75 also drives the I-shaped roller 78 to rotate, which in turn drives the fixing plate 782 to rotate. During this rotation, the fixing plate 782 actively pulls the fertilizer bag hooked by the inclined spur plate 76 towards the inclined spur plate 76, thereby enhancing the contact strength between the fertilizer bag and the inclined spur plate 76 and ensuring that the fertilizer bag is firmly hooked, preventing it from slipping or falling off during movement. The two sliders 781 are mainly used to support the I-shaped roller 78.

[0035] During the rotation of the drive roller 72, the drive roller 72 drives the elliptical groove plate 710 to rotate. As the elliptical groove plate 710 rotates, its elliptical groove pushes the sliding column 715, causing the elastic telescopic rod 711 on one side to move reciprocally up and down along the outer wall of the through-groove plate 79. With the cooperation of the elastic telescopic rods 711 on both sides, the elastic telescopic rods 711 on both sides drive the connecting plate 712 and the spikes 713 to move reciprocally up and down. Each time the inclined spike plate 76 moves the fertilizer bag to the position of the through-groove plate 79, the spikes 713 insert into the fertilizer bag. Each time the spike 713 moves downward, it pulls the fertilizer bag downward, facilitating the separation of the fertilizer bag from the inclined spike plate 76. Simultaneously, when the connecting plate 712 moves downward and reaches the position of the trapezoidal plate 714, the trapezoidal plate 714 pushes the connecting plate 712 away from the through-slot plate 79. The connecting plate 712 causes the telescopic end of the elastic telescopic rod 711 to stretch, and the connecting plate 712 moves along with the spike 713, thereby separating the spike 713 from the fertilizer bag and ensuring that the fertilizer bag can effectively fall at the discharge port of the round shell 71.

[0036] Please see Figure 1 - Figure 10Based on the above embodiments, in another embodiment of the present invention, an anti-crushing device 8 is provided at the L-shaped frame 77. The anti-crushing device 8 includes two turntables 81 and two track plates 84. The two turntables 81 are respectively fixed on both sides of the rotating shaft of the driven roller 73. A fixing column 82 is fixed at the eccentric position on the side of the two turntables 81 that is far apart from each other. The two track plates 84 are respectively fixed on the side of the two L-shaped frames 77 that is far apart from each other. A U-shaped plate 83 is slidably installed on the side of the two track plates 84 that is far apart from each other. The fixing column 82 is slidably installed inside the U-shaped plate 83. Both U-shaped plates 83 have L-shaped rods 85 fixed to their bottoms, and a semi-circular plate 86 is fixed between the bottoms of the two L-shaped rods 85. With the above structure, the U-shaped plates 83 drive the semi-circular plate 86 to move back and forth through the L-shaped rods 85. The semi-circular plate 86 pushes the fertilizer bag piled up on one side of the filter cylinder 61 toward the inclined barb plate 76. Thus, the reciprocating motion of the semi-circular plate 86 can accurately push the fertilizer bag to the hooking area of ​​the inclined barb plate 76, ensuring that the fertilizer bag can accurately enter the effective contact range of the inclined barb plate 76 and reduce hooking failures caused by positional deviations.

[0037] The anti-overcrowding device 8 also includes two vertical rods 87 and two arc-shaped plates 89. The two vertical rods 87 are respectively fixed to the top of the two sliders 781. A push column 88 is fixed between the tops of the two vertical rods 87. The two arc-shaped plates 89 are respectively fixed to the tops of the two U-shaped plates 83. Several semi-arc blocks are evenly and equidistantly fixed to the top of the arc-shaped plates 89. The push column 88 is located on the movement trajectory of the semi-arc blocks of the arc-shaped plates 89. Through the above structure, the semi-arc blocks of the arc-shaped plates 89 push the push column 88 to drive the sliders 781 to shake up and down. The sliders 781 drive the transmission belt 75 to shake up and down through the I-shaped roller 78. The transmission belt 75 drives the fertilizer bag hooked by the inclined bar 76 to shake through the inclined bar 76. The fertilizer bag will shake off the fertilizer adhering to it, thereby reducing the amount of fertilizer loss during the process of the fertilizer bag hooked by the inclined bar 76 being removed from the filter cylinder 61.

[0038] In use, the driven roller 73 rotates, driving the turntable 81 to rotate. The turntable 81 drives the fixed column 82 to rotate, and the fixed column 82 slides along the inside of the loop plate 83. The fixed column 82 pushes the loop plate 83 to move back and forth along the outer wall of the track plate 84. The loop plate 83 drives the semicircular plate 86 to move back and forth via the L-shaped rod 85. The semicircular plate 86 pushes the fertilizer bags piled up on one side of the filter cylinder 61 toward the inclined bar 76, so that the reciprocating motion of the semicircular plate 86 can accurately push the fertilizer bags to the hooking area of ​​the inclined bar 76, ensuring that the fertilizer bags can accurately enter the effective contact range of the inclined bar 76 and reduce hooking failures caused by positional deviations. At the same time, the loop plate 83 moves back and forth. During the movement, the U-shaped plate 83 drives the arc block plate 89 to move. The semi-arc block of the arc block plate 89 pushes the bottom of the push column 88, causing the push column 88 to move upward. The push column 88 drives the I-shaped roller 78 to move upward through the slider 781. When the semi-arc block of the arc block plate 89 no longer pushes the bottom of the push column 88, the slider 781 will be reset by the corresponding spring. The slider 781 drives the I-shaped roller 78 to reset and move downward. This process repeats, causing the I-shaped roller 78 to push the transmission belt 75 to shake up and down. The transmission belt 75 drives the fertilizer bag hooked by the inclined bar 76 to shake through the inclined bar 76. The fertilizer bag will shake off the fertilizer adhering to it, thereby reducing the amount of fertilizer loss during the process of the fertilizer bag hooked by the inclined bar 76 being removed from the filter cylinder 61.
