Description

Technical Field

[0001] The invention belongs to the technical field of biofertilizer processing, and in particular relates to a special conveying device for biofertilizer. Background Art

[0002] Biofertilizer is a product containing specific living microorganisms. These microorganisms can produce biologically active substances during their growth and reproduction in the soil, improve plant nutrition, soil fertility, and plant stress resistance, thereby promoting plant growth and achieving the purpose of increasing production and improving the quality of agricultural products. In the production process of biofertilizer, various raw materials such as microbial agents, carriers, nutrients, etc. need to be fully mixed and stirred, and the mixed biofertilizer is granulated for easy packaging and use. In this process, the mixed materials need to be transported to the granulator for granulation through a conveying device.

[0003] However, the existing conveying devices often have the following technical problems in the process of conveying biofertilizer: When conveying different types of biofertilizers, the viscosity of the biofertilizers varies, and the conveying speed of the existing conveying device for the biofertilizers is often fixed. When the viscosity of the biofertilizers is relatively strong, the conveying speed cannot be reduced, and the conveying speed is easily too fast, resulting in accumulation or slipping of the biofertilizers, affecting the uniform conveying of the biofertilizers, affecting the subsequent processing effect of the biofertilizers, and reducing the product quality of the biofertilizers. When the viscosity of the biofertilizers is relatively weak, the relatively loose biofertilizers can be stably conveyed at a higher speed, but the conveying speed cannot be increased at this time, resulting in limited conveying efficiency of the biofertilizers, affecting the production efficiency of the biofertilizers; In the process of conveying bio-fertilizer, the bio-fertilizer is easy to accumulate on the conveyor belt. At the same time, the accumulation position is affected by many factors such as the condition of the conveyor belt itself, the characteristics of the bio-fertilizer and the external environment, and there is a large degree of randomness, which makes the existing conveying device unable to accurately level the accumulation position of the bio-fertilizer. As a result, the accumulation of bio-fertilizer leads to discontinuous supply of bio-fertilizer, which interrupts the feeding of the subsequent granulator, and causes the granulator to idle or start and stop frequently, which not only reduces the service life of the granulator, but also increases energy consumption and production costs.

The scraper is hinged to a roller at one end close to the annular track through a hinge seat, and the roller periodically contacts and rolls with the annular track and the arc-shaped trapezoidal protrusion.

[0013] Compared with the existing technology, the advantages of this biofertilizer special conveying device are: The present invention is provided with a speed regulating mechanism. During the conveying process, the biofertilizer is conveyed into the feeding channel. When the biofertilizer flows through the transmission roller, the biofertilizers with different viscosities can drive the rotation speeds of the transmission roller to be different. When the biofertilizer has strong viscosity, the adhesion between the biofertilizer and the transmission roller is strong, so that the transmission roller obtains a higher rotation speed. The PLC controller controls the power reduction of the first motor according to the faster changing frequency of the electromagnetic coil. When the viscosity of the biofertilizer is relatively strong, the biofertilizer is conveyed at a relatively slow conveying speed to avoid accumulation or slipping of the biofertilizer due to excessively fast conveying speed. When the viscosity of the biofertilizer is relatively weak, the adhesion between the biofertilizer and the transmission roller is weak. When the biofertilizer flows through, part of the energy is lost due to the sliding or rolling of the biofertilizer itself. The rotation speed of the transmission roller is relatively low. The PLC controller controls the power of the first motor to be increased. When the viscosity of the biofertilizer is relatively weak, the biofertilizer is conveyed at a faster conveying speed, so as to improve the conveying efficiency of the biofertilizer and effectively improve the production efficiency.

[0014] The present invention is provided with an anti-accumulation mechanism. During the conveying process, a plurality of laser distance measuring sensors respectively emit laser beams to the surface of the biofertilizer on the conveyor belt, and measure the time for the reflected light to return, so as to calculate the distance between the laser distance measuring sensor and the surface of the biofertilizer. When the biofertilizer is accumulated, the distance value of the position will be smaller than that of the normal area, so as to judge the accumulation position, and control the slider to move horizontally along the threaded rod to the accumulation position of the biofertilizer through the PLC controller, and squeeze the surrounding side of the accumulated biofertilizer flat through the electric control telescopic rod and the pressing plate, so as to accurately flatten the accumulation position of the biofertilizer, avoid the discontinuous supply of the biofertilizer by the conveyor device to the granulator, and prevent the granulator from idling and frequent start and stop, thereby improving the service life of the granulator and reducing energy consumption.

[0015] The present invention provides a blowing mechanism. During the conveying process, the rotation of the transmission roller shaft will also drive the rotating rod to rotate through the bevel gear set, and then drive the axial flow fan blade to rotate, so that the outside air continuously impacts the top of the conveyor belt through the blowing pipe, which has a blowing effect on the bio-fertilizer, so that a certain gap is maintained between the bio-fertilizer particles, and accumulation due to mutual squeezing and adhesion of the particles is avoided, thereby ensuring that the bio-fertilizer is evenly distributed on the conveyor belt and making the conveying process smoother.

[0016] The present invention arranges a rotating mechanism. During the transmission process, the transmission rod rotates synchronously, and the first rack is driven to extend periodically from the slide groove through the incomplete gear, and is reset periodically under the elastic force of the first spring, and further drives the second rack to perform reciprocating horizontal displacement, so that the transmission gear reciprocates and rotates in opposite directions, so that the exhaust pipe can swing back and forth, so that the air can blow the bio-fertilizer at different angles when discharged, and the uniformity of the bio-fertilizer in the transmission process is further improved.

[0017] The present invention provides a scraping mechanism. During the conveying process, the scraping rod rotates so that the scraper on the scraping rod periodically contacts the conveyor belt below, thereby cleaning the conveyor belt that is conveyed to the bottom and has not contacted with the bio-fertilizer, thereby preventing the bio-fertilizer from being adhered to the conveyor belt for a long time, which makes it difficult to clean the conveyor belt later.

[0018] The present invention provides a sliding mechanism. During the cleaning process, the scraping rod rotates, and since the roller periodically contacts and rolls with the annular track and the arc-shaped trapezoidal protrusion, the scraper can be driven to perform reciprocating horizontal displacement along the strip groove, so that the scraper can clean and scrape the surface of the conveyor belt along an oblique angle when in contact with the conveyor belt, so that the biofertilizer is more effectively separated from the conveyor belt, and the cleaning effect of the conveyor belt is improved.

DETAILED DESCRIPTION

[0021] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0022] Example: Refer to Figures 1 to 7 , a special conveying device for biofertilizer, comprising: The device body 1 has two conveying rollers 11 rotatably connected between the inner walls of both sides of the device body 1, a sprocket set is provided between the two conveying rollers 11, a conveying belt 12 is sleeved between the two conveying rollers 11, and a first motor 13 for driving the two conveying rollers 11 to rotate synchronously is provided on the outer wall of the device body 1; Specifically, in actual use, one of the two conveying rollers 11 can be driven to rotate by the first motor 13, and the other conveying roller 11 can be driven to rotate synchronously by the sprocket group, so that the conveyor belt 12 starts to convey the biofertilizer. The sprocket group here can adopt common sprockets and chains, so it will not be described in detail.

[0023] Specifically, one end of the device body 1 is fixedly connected with an inclined feeding plate, which is directly opposite to the feed inlet of the granulator, and can convey the biofertilizer to the granulator for granulation.

[0024] The speed regulating mechanism 2 is used for adaptively adjusting the conveying speed according to the viscosity of the bio-fertilizer. The speed regulating mechanism 2 comprises a detection box 21 fixedly connected to the top of the device body 1. The detection box 21 is provided with a feeding channel 22. The inner sealing and rotatable connection of the detection box 21 is a transmission roller 23. Half of the transmission roller 23 extends into the feeding channel 22. One end of the roller shaft of the transmission roller 23 extends outside the detection box 21 and is fixedly connected to a detection ring 24. The detection ring 24 is divided into a magnetic area 25 and a magnetic isolation area 26. An electromagnetic coil 27 is fixedly connected to the outer wall of the detection box 21 on one side close to the detection ring 24. A PLC controller 28 is fixedly connected to the outer wall of the device body 1. The PLC controller 28 controls the power of the first motor 13 according to the period of the electric field change of the electromagnetic coil 27. Specifically, a feeding hopper communicated with the feeding channel 22 is fixedly connected to the upper end of the detection box 21 .

[0025] Specifically, the detection box 21 is fixedly connected to the upper ends of the two side walls of the device body 1 through a first support rod.

[0026] Specifically, the PLC controller 28 is also called a programmable logic controller, which can automatically control electrical equipment according to programmed logic. Here, the power of the first motor 13 can be controlled according to the frequency of the electric field change of the electromagnetic coil 27.

[0027] In view of the problem that in the prior art, when different types of bio-fertilizers are conveyed, the viscosity of the bio-fertilizers varies, and the conveying speed of the existing conveying device for the bio-fertilizers is often fixed, and when the viscosity of the bio-fertilizers is relatively strong, the bio-fertilizers are prone to accumulation or slippage, and when the viscosity of the bio-fertilizers is relatively weak, the conveying efficiency of the bio-fertilizers is limited, the present invention provides a speed regulating mechanism 2, and during the conveying process, the bio-fertilizers are conveyed into the feeding channel 22. When the bio-fertilizers flow through the driving roller 23, the bio-fertilizers of different viscosities can drive the rotating speeds of the driving roller 23 to be different, thereby causing the following effects: When the biofertilizer is highly viscous, the adhesion between the biofertilizer and the transmission roller 23 is strong. When the biofertilizer flows, the biofertilizer can more effectively transfer its own kinetic energy to the transmission roller 23, so that the transmission roller 23 obtains a higher rotation speed, thereby driving the detection ring 24 to rotate at a relatively fast speed through the roller shaft of the transmission roller 23. Since the electric field of the electromagnetic coil 27 can be changed once by the magnetic area 25 on the detection ring 24 when it rotates one circle, the frequency of the electric field change of the electromagnetic coil 27 can be faster when the detection ring 24 rotates faster. The electromagnetic coil 27 can further feed back the faster change frequency to the PLC controller and control the power of the first motor 13 to reduce. When the biofertilizer is relatively viscous, the biofertilizer is transmitted at a relatively slow transmission speed to avoid the accumulation or slipping of the biofertilizer caused by excessive transmission speed. When the viscosity of the biofertilizer is weak, the adhesion between the biofertilizer and the transmission roller 23 is weak. When the biofertilizer flows through, part of the energy will be lost due to the sliding or rolling of the biofertilizer itself, and the energy transmitted to the transmission roller 23 is relatively small, so that the rotation speed of the transmission roller 23 is low, so that the roller shaft of the transmission roller 23 drives the detection ring 24 to rotate relatively slowly, and the electromagnetic coil 27 feeds back the slower changing frequency to the PLC controller 28, and controls the power of the first motor 13 to increase, so that when the viscosity of the biofertilizer is relatively weak, the biofertilizer is transmitted at a faster transmission speed, thereby improving the transmission efficiency of the biofertilizer and effectively improving the production efficiency; Through the above method, the conveying speed of the conveyor belt 12 for the bio-fertilizer can be adaptively adjusted according to the viscosity of the bio-fertilizer, thereby avoiding the accumulation or sliding of the bio-fertilizer and improving the conveying efficiency of the bio-fertilizer as much as possible, thereby improving the production efficiency of the bio-fertilizer.

[0028] The anti-accumulation mechanism 3 is used to detect the accumulation position of the bio-fertilizer during the bio-fertilizer transmission process and flatten it. The anti-accumulation mechanism 3 includes a U-shaped plate 31 fixedly connected to the upper end of the device body 1, a threaded rod 32 is rotatably connected between the inner walls on both sides of the U-shaped plate 31, a second motor 33 for driving the threaded rod 32 is fixedly connected to the outer wall of one side of the U-shaped plate 31, a slider 34 is threadedly connected to the threaded rod 32, the slider 34 is slidably connected to the lower wall of the U-shaped plate 31, the lower end of the slider 34 is fixedly connected to an electric control telescopic rod 35, the telescopic end of the electric control telescopic rod 35 is fixedly connected to a flat plate 36, the lower end of the U-shaped plate 31 is fixedly connected to a plurality of laser ranging sensors 37 distributed in a linear array, and the PLC controller 28 controls the position of the slider 34 on the threaded rod 32 according to the distance difference between the plurality of laser ranging sensors 37.

[0029] Specifically, the PLC controller 28 can also control the second motor 33 according to the data collected by the laser ranging sensor 37 to adjust the position of the slider 34 on the threaded rod 32 .

[0030] Specifically, when the laser ranging sensor 37 transmits the collected data to the PLC controller 28, the biofertilizer accumulation position can be determined, and different electrical signals are set according to different accumulation positions to control the second motor 33, thereby controlling the position of the slider 34 on the threaded rod 32, wherein the electrical signals at different accumulation positions of the biofertilizer correspond to different positions of the slider 34, and the position of the slider 34 is always opposite to the accumulation position of the biofertilizer.

[0031] Specifically, the distance between two adjacent laser distance measuring sensors 37 is 5 cm, which ensures accurate detection of the bio-fertilizer accumulation position.

[0032] In view of the problem that the accumulation position of biofertilizer cannot be accurately leveled in the prior art, and the accumulation of biofertilizer leads to discontinuous supply of biofertilizer, which causes interruption of feeding of subsequent granulators, the present invention sets an anti-accumulation mechanism 3. During the transmission process, multiple laser distance sensors 37 respectively emit laser beams to the surface of biofertilizer on the conveyor belt 12, and measure the time for the reflected light to return, so as to calculate the distance between the laser distance sensor 37 and the surface of biofertilizer, and transmit all the data collected by the laser distance sensor 37 to the PLC controller 28. When biofertilizer is accumulated, the distance value of the position will be less than Normal area, thereby judging the accumulation place, and controlling the second motor 33 to drive the threaded rod 32 to rotate through the PLC controller 28, so that the slider 34 can move horizontally along the threaded rod 32 to the accumulation place of the bio-fertilizer, and then the electric-controlled telescopic rod 35 drives the pressing plate 36 to move downward, and the accumulated bio-fertilizer is squeezed and flattened by the pressing plate 36, which can accurately flatten the accumulation position of the bio-fertilizer, avoid the discontinuous supply of bio-fertilizer by the conveying device to the granulator, prevent the granulator from idling and frequent start and stop, and improve the service life of the granulator, while reducing energy consumption.

[0033] The device body 1 is also provided with a blowing mechanism 4, which is used to blow the biofertilizer during the transmission process to prevent the biofertilizer from adhering to the conveyor belt 12. The blowing mechanism 4 includes a blowing pipe 41 fixedly connected to the top of the device body 1, and one end of the roller shaft of the transmission roller 23 away from the detection ring 24 extends to the inside of the blowing pipe 41. A mounting block 42 is fixedly connected to the inside of the blowing pipe 41, and a rotating rod 43 is rotatably connected to the mounting block 42. A bevel gear set 44 is provided between the rotating rod 43 and the roller shaft of the transmission roller 23, and an axial flow fan blade 45 is fixedly connected to the rotating rod 43. The lower end of the blowing pipe 41 is sealed and rotatably connected to an exhaust pipe 46.

[0034] Specifically, the blowing pipe 41 is fixedly connected to the upper ends of the two side walls of the device body 1 through the second support rod.

[0035] It is worth mentioning that, in the present invention, by setting the blowing mechanism 4, during the conveying process, the rotation of the roller shaft of the transmission roller 23 will also drive the rotating rod 43 to rotate through the bevel gear set 44, and then drive the axial flow fan blade 45 to rotate, so that the outside air continuously impacts the top of the conveyor belt 12 through the blowing pipe 41, which has a blowing effect on the bio-fertilizer, so that a certain gap is maintained between the bio-fertilizer particles, and the accumulation due to mutual squeezing and adhesion of the particles is avoided, so as to ensure that the bio-fertilizer is evenly distributed on the conveyor belt, and the conveying process is smoother.

[0036] A rotating mechanism 5 is also provided below the blowing pipe 41 for continuously adjusting the blowing angle during the conveying process. The rotating mechanism 5 includes a transmission gear 51 fixedly connected to the side wall of the exhaust pipe 46. A transmission rod 52 is rotatably connected to one side wall of the device body 1. An incomplete gear 53 is fixedly connected to the end of the transmission rod 52 close to the transmission rod 52. A baffle 54 is fixedly connected to the position of the device body 1 between the two side walls, and the baffle 54 is sealingly and slidably connected to the conveyor belt 12. A slide groove 55 is provided on the side wall of the baffle 54. A first rack 56 is slidably connected to the slide groove 55 in the horizontal direction. A first spring is provided between the first rack 56 and the inner wall of the slide groove 55. The incomplete gear 53 periodically meshes with the first rack 56. A second rack 57 is fixedly connected to the end of the first rack 56 close to the transmission gear 51. The second rack 57 meshes with the transmission gear 51. A first synchronization component is provided between the transmission rod 52 and the roller shaft of one of the conveying rollers 11.

[0037] Specifically, the roller shaft of one of the conveying rollers 11 extends outside the device body 1 , and the first synchronization component includes a first synchronization wheel 58 fixedly connected to the transmission rod 52 and the roller shaft of one of the conveying rollers 11 , and a first synchronization belt 59 is sleeved between the two first synchronization wheels 58 .

[0038] It should be noted that, in the present invention, by setting the rotating mechanism 5, during the conveying process, one of the conveying rollers 11 can drive the transmission rod 52 to rotate synchronously through the first synchronization component, and further drive the first rack 56 to periodically extend from the slide groove 55 through the incomplete gear 53, and periodically reset under the elastic force of the first spring, so that the first rack 56 performs reciprocating horizontal displacement, further drives the second rack 57 to perform reciprocating horizontal displacement, so that the transmission gear 51 reciprocates and rotates in opposite directions, so that the exhaust pipe 46 can swing back and forth, so that the air can blow the biofertilizer at different angles when it is discharged, and further improve the uniformity of the biofertilizer during transmission.

[0039] A scraping mechanism 6 is provided at a position below the conveyor belt 12 in the device body 1, which is used to continuously clean the conveyor belt 12 transmitted to the bottom. The scraping mechanism 6 includes a scraping rod 61 that is rotatably connected to a side wall of the device body 1, and a scraper 62 is provided on the scraping rod 61. A second synchronization component is provided between the scraping rod 61 and the roller shaft of one of the conveying rollers 11.

[0040] Specifically, the second synchronous assembly includes a second synchronous wheel 63 fixedly connected to the scraping rod 61 and the roller shaft of one of the conveying rollers 11 , and a second synchronous belt 64 is sleeved between the two second synchronous wheels 63 .

[0041] Specifically, the conveyor belt 12 is made of rubber material with high elasticity, flexibility and good tensile properties, so that the conveyor belt 12 can be squeezed by the scraper 62 when in contact with the scraper 62 and deformed to a certain extent, and return to its original shape when not squeezed by the scraper 62, thereby preventing the scraper 62 from deforming the conveyor belt 12 during the scraping process of the conveyor belt 12. At the same time, the conveyor belt 12 always fits the conveying roller 11 to ensure the transmission efficiency of the bio-fertilizer.

[0042] Specifically, a storage frame is provided inside the device body 1 for storing the scraped bio-fertilizer.

[0043] Taking into account that biofertilizer is easy to adhere to the conveyor belt 12 during the transmission process, the present invention is provided with a scraping mechanism 6. During the transmission process, one of the conveying rollers 11 can also drive the scraping rod 61 to rotate through the second synchronous component, so that the scraper 62 on the scraping rod 61 periodically contacts the conveyor belt 12 below, and has a cleaning effect on the conveyor belt 12 that is transmitted to the bottom and not in contact with the biofertilizer, thereby preventing the biofertilizer from adhering to the conveyor belt 12 for a long time, resulting in difficulty in subsequent cleaning of the conveyor belt 12, and at the same time preventing different types or batches of biofertilizers from being mixed with the biofertilizer being transmitted during the transmission process, causing cross contamination, resulting in unstable product composition and performance, and affecting the use effect of the biofertilizer.

[0044] The device body 1 is also provided with a sliding mechanism 7 at a position below the conveyor belt 12, which is used to horizontally displace the scraper 62 along the scraping rod 61 during operation to improve the cleaning effect of the conveyor belt 12. The sliding mechanism 7 includes a strip groove 71 opened on the rod body of the scraper rod 61, and the scraper 62 is slidably connected to the inner wall of the strip groove 71, and the length of the strip groove 71 is greater than the length of the scraper 62. A stop block 72 is fixedly connected to one side of the scraper rod 61, and a second spring 73 is provided between the scraper 62 and the stop block 72. An annular track 74 is fixedly connected to the inner wall of one side of the device body 1, and an arc-shaped trapezoidal protrusion 75 is fixedly connected to the annular track 74. The end of the scraper 62 close to the annular track 74 is hinged with a roller 76 through a hinge seat, and the roller 76 periodically contacts and rolls with the annular track 74 and the arc-shaped trapezoidal protrusion 75.

[0045] In addition, the present invention provides a sliding mechanism 7. During the cleaning process, the scraping rod 61 rotates, and since the roller 76 periodically contacts and rolls with the annular track 74 and the arc-shaped trapezoidal protrusion 75, when the scraper 62 contacts the conveyor belt 12, the scraper 62 can be driven to perform reciprocating horizontal displacement along the strip groove 71, so that when the scraper 62 contacts the conveyor belt 12, the surface of the conveyor belt 12 can be cleaned and scraped along an oblique angle. The action of the scraper 62 can be decomposed into two components along the length direction of the conveyor belt 12 and along the width direction of the conveyor belt 12. Through the action of the components in the two directions, the adhesion of the biofertilizer can be dispersed and overcome from different angles. The component in the length direction can apply a pulling force in the direction of movement of the biofertilizer, and the component in the width direction can apply a lateral force perpendicular to the direction of movement of the biofertilizer, so that the biofertilizer can be more effectively separated from the conveyor belt 12, thereby improving the cleaning effect of the conveyor belt 12.

[0046] The present invention can be explained by the following operation mode: The biofertilizer is transported into the feeding channel 22, and falls on the conveyor belt 12. One of the two conveyor rollers 11 is driven to rotate by the first motor 13, and the other conveyor roller 11 is driven to rotate synchronously by the sprocket group. The biofertilizer is transported to the granulator through the conveyor belt 12 for granulation; When the biofertilizer flows through the transmission roller 23, biofertilizers with different viscosities can drive the transmission roller 23 to rotate at different speeds. When the biofertilizer has strong viscosity, the adhesion between the biofertilizer and the transmission roller 23 is strong, the transmission roller 23 obtains a higher rotation speed, and the detection ring 24 rotates faster, so that the frequency of the electric field change of the electromagnetic coil 27 is faster. The power of the first motor 13 is controlled to be reduced through the PLC controller. When the viscosity of the biofertilizer is relatively strong, the biofertilizer is transmitted at a relatively slow transmission speed. When the viscosity of the biofertilizer is relatively weak, the adhesion between the biofertilizer and the transmission roller 23 is weak. When the biofertilizer flows through, part of the energy will be lost due to the sliding or rolling of the biofertilizer itself, and the energy transmitted to the transmission roller 23 is relatively small, so that the rotation speed of the transmission roller 23 is low. The PLC controller 28 controls the power of the first motor 13 to increase, and when the viscosity of the biofertilizer is relatively weak, the biofertilizer is transmitted at a faster transmission speed. During the conveying process, a plurality of laser distance measuring sensors 37 respectively emit laser beams to the surface of the biofertilizer on the conveyor belt 12, and measure the time for the reflected light to return, thereby calculating the distance between the laser distance measuring sensor 37 and the surface of the biofertilizer, and transmitting all the data collected by the laser distance measuring sensors 37 to the PLC controller 28. When the biofertilizer is piled up, the distance value at this position will be smaller than the normal area, so as to judge the accumulation place, and the slider 34 is moved horizontally along the threaded rod 32 to the accumulation place of the biofertilizer through the PLC controller 28, and then the pressing plate 36 is driven to move downward by the electric control telescopic rod 35, and the accumulated biofertilizer is squeezed and flattened by the pressing plate 36. The rotation of the roller shaft of the transmission roller 23 will also drive the rotating rod 43 to rotate through the bevel gear set 44, and then drive the axial flow fan blades 45 to rotate, so that the outside air continuously impacts the top of the conveyor belt 12 through the blowing pipe 41, which has a blowing effect on the biofertilizer; During the rotation of one of the conveying rollers 11, the transmission rod 52 is driven to rotate synchronously through the first synchronization component, and the first rack 56 is further driven to extend periodically from the slide slot 55 through the incomplete gear 53, and is periodically reset under the elastic force of the first spring, driving the second rack 57 to perform reciprocating horizontal displacement, and the exhaust pipe 46 is swung back and forth under the action of the transmission gear 51, so as to blow the biofertilizer at different angles; During the rotation of one of the conveying rollers 11, the second synchronous component can also drive the scraping rod 61 to rotate, so that the scraper 62 on the scraping rod 61 periodically contacts the conveyor belt 12 below, thereby cleaning the conveyor belt 12 that is conveyed to the bottom and not in contact with the biofertilizer; During the rotation of the scraping rod 61, the roller 76 periodically rolls in contact with the annular track 74 and the arc-shaped trapezoidal protrusion 75, driving the scraper 62 to perform reciprocating horizontal displacement along the strip groove 71, so that when the scraper 62 contacts the conveyor belt 12, it can clean and scrape the surface of the conveyor belt 12 along an oblique angle. The force of the scraper 62 can be decomposed into two components along the length direction of the conveyor belt 12 and along the width direction of the conveyor belt 12, so that the biofertilizer can be separated from the conveyor belt 12 more effectively.
