Description

Technical Field

[0001] This invention relates to the field of belt conveyor technology, and more particularly to a belt conveyor for fertilizer production. Background Technology

[0002] Fertilizers are substances that provide one or more essential nutrients for plants, improve soil properties, and enhance soil fertility. They are one of the material bases of agricultural production and mainly include ammonium phosphate fertilizers, water-soluble fertilizers containing macronutrients, fertilizers containing micronutrients, bio-fertilizers, organic fertilizers, and multi-dimensional field energy concentrated organic fertilizers. In order to improve the continuity and efficiency of material transportation, belt conveyors are required in fertilizer production.

[0003] A search revealed an existing technology (publication number: CN215754872U) for a belt conveyor in fertilizer production. The technology describes a conveyor that "includes a conveyor support and a conveyor belt. The conveyor further includes: an adhesive material cleaning structure, installed on the conveyor support and in contact with the surface of the conveyor belt, for scraping off and collecting material adhering to the conveyor belt before it falls off; and a conveying structure, disposed on the conveyor support and connected to the adhesive material cleaning structure, for conveying the material collected by the adhesive material cleaning structure to the conveyor belt." This technical solution, by incorporating an adhesive material cleaning structure, conveniently scrapes off and collects material adhering to the conveyor belt before it falls off, thereby improving the practicality of the belt conveyor.

[0004] However, the existing technology only uses a scraper to clean the fertilizer raw materials adhering to the conveyor, which has a limited cleaning effect. Fertilizer adhering to the conveyor will increase the load on the conveyor and thus reduce the service life of the conveyor. Therefore, it is necessary to design a belt conveyor for fertilizer production. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that existing designs only use one scraper to clean fertilizer material adhering to the conveyor, which has limited cleaning effect. Fertilizer adhering to the conveyor increases the load on the conveyor, thereby reducing the service life of the conveyor.

[0009] Preferably, the insert is made of magnet, the roller is made of ferritic stainless steel, the magnetic groove is magnetically connected to the insert, and the sweeping head is made of PP plastic.

[0010] Preferably, a first tensioning rod is installed on each of the two outer walls of the belt conveyor body via a torsion spring shaft, and a tensioning wheel is installed at the other end of the first tensioning rod via a shaft. A second tensioning rod is installed on the outer wall of the first tensioning rod via a torsion spring shaft, and a tensioning roller is installed at the other end of the second tensioning rod via a shaft. The tensioning wheel presses against the top of the first synchronous belt, and the tensioning roller presses against the top of the second synchronous belt.

[0011] Preferably, a pair of brackets are provided at the bottom of the belt conveyor body, and the two ends of the brackets are respectively screwed to two columns of the belt conveyor body. A waste frame is clamped between the two brackets, and a water tank is clamped between the two brackets.

[0012] Preferably, a flow guide pump is screwed to the top of the water tank, and a corrugated telescopic pipe is inserted into the output end of the flow guide pump. A lifting frame is screwed to the other end of the bottom of the belt conveyor body, and a lifting plate is slidably installed inside the lifting frame. Several reinforcing rods are welded at equal intervals on one side of the outer wall of the lifting plate. A spray frame is provided on one side of the outer side of the lifting plate, and the spray frame is screwed and fixed to the reinforcing rods. The other end of the corrugated telescopic pipe is inserted and connected to the bottom of the spray frame. Several atomizing nozzles are provided at equal intervals on the top of the spray frame, and the atomizing nozzles are inclined.

[0013] Preferably, a screw is inserted into the center of the bottom of the lifting frame, and the top end of the screw is connected to the top of the inner wall of the lifting frame through a bearing. A handwheel is welded to the bottom end of the screw, and the screw is connected to the lifting plate through a thread.

[0014] Preferably, a second bracket is screwed to both sides of the top of the belt conveyor body, and a second motor is screwed to the second bracket.

[0016] Compared with the prior art, the present invention provides a belt conveyor for fertilizer production, which has the following beneficial effects:

[0017] 1. In this invention, during the operation of the belt conveyor body driven by the first motor, the first synchronous pulley rotates synchronously. The first synchronous belt drive can drive the cleaning roller to rotate. The fourth synchronous pulley, the third synchronous pulley, and the second synchronous belt can drive the transmission roller to rotate when the cleaning roller rotates, thereby driving the conveyor belt. When the conveyor belt is running, the scraper on its surface moves forward, while the bottom of the belt conveyor body moves backward. When the scraper contacts the bottom of the belt conveyor body, the relative force will improve the scraping effect. Furthermore, the spring telescopic rod can increase the fit between the scraper and the belt conveyor body, thus ensuring the scraping effect. After scraping, the broom head cleans up dust and other fine particles on the belt conveyor body. The broom head can be easily removed and replaced using a magnetic groove and plug-in method. This cleaning method has excellent cleaning effect and can effectively remove fertilizer attached to the belt conveyor body, thereby reducing the load on the conveyor and increasing the service life of the conveyor.

[0018] 2. The waste bin collects the fertilizer material scraped off by the scraper. A guide pump and corrugated telescopic pipe extract water from the tank and transport it to the spray frame, where it is sprayed from the atomizing nozzles. The impact force of the water flow helps to detach the material from the conveyor belt, reducing the difficulty of scraping. The position of the spray frame can be adjusted by turning the handwheel. When the spray frame is close to the bottom of the conveyor belt, the impact force of the water flow is enhanced, resulting in the best rinsing effect. A second motor drives a sector gear to swing back and forth. Under the action of the drive rod and tooth groove, the limit plate moves back and forth, thus pushing the fertilizer material towards the center of the conveyor belt during transport, preventing deviation and ensuring efficient delivery.

[0021] 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.

[0022] Example 1: Please see Figure 1-6A belt conveyor for fertilizer production includes a belt conveyor body 1. A first support 2 is welded to one outer wall of the belt conveyor body 1, and a first motor 3 is screwed onto the first support 2. The output end of the first motor 3 is fixedly connected to a roller of the belt conveyor body 1, and both ends of the roller are welded with first synchronous pulleys 4. A cleaning roller 5 is provided at the bottom of the belt conveyor body 1. First fixing frames 6 are screwed onto both sides of the bottom of the belt conveyor body 1, and both ends of the cleaning roller 5 are respectively inserted into the two first fixing frames 6. Both ends of the cleaning roller 5 are welded with second synchronous pulleys 7. The first synchronous pulleys 4 and the first synchronous pulleys 5 are connected to the first synchronous pulleys 6. A first synchronous belt 8 is fitted onto the two synchronous pulleys 7. Two pairs of second fixed frames 9 are screwed to the bottom of the belt conveyor body 1, and a transmission roller 10 is inserted between each pair of second fixed frames 9. A conveyor belt 11 is fitted onto the two transmission rollers 10. A third synchronous pulley 12 is welded to both ends of the cleaning roller 5. A fourth synchronous pulley 13 is welded to both ends of one transmission roller 10. A second synchronous belt 14 is fitted onto the third synchronous pulley 12 and the fourth synchronous pulley 13. Two rubber pads 15 are screwed onto the conveyor belt 11, and the two rubber pads 15 are arranged opposite each other. A pair of spring telescopic rods 1 are screwed onto the rubber pads 15. 6. A scraper 17 is screwed between the telescopic ends of the two spring telescopic rods 16. The first synchronous wheel 4 and the second synchronous wheel 7 are the same size, and the third synchronous wheel 12 and the fourth synchronous wheel 13 are the same size. The scraper 17 is made of stainless steel. The cleaning roller 5 is composed of a roller body 501, magnetic grooves 502, insert blocks 503, and a broom head 504. The two ends of the roller body 501 are respectively connected to two first fixed frames 6. Several magnetic grooves 502 are equally spaced on the outer wall of the roller body 501, and insert blocks 503 are inserted into the inside of the magnetic grooves 502. A broom head 504 is screwed onto the outer wall of the insert blocks 503. The insert blocks 503 are... Made of magnets, roller 501 is made of ferritic stainless steel, and magnetic groove 502 is magnetically connected to insert block 503. Sweeping head 504 is made of PP plastic. The outer walls of both sides of the belt conveyor body 1 are equipped with first tension rods 18 through torsion spring shafts, and the other end of the first tension rod 18 is equipped with a tension wheel 19 through a shaft. The outer wall of the first tension rod 18 is equipped with a second tension rod 20 through a torsion spring shaft, and the other end of the second tension rod 20 is equipped with a tension roller 21 through a shaft. The tension wheel 19 presses against the top of the first synchronous belt 8, and the tension roller 21 presses against the top of the second synchronous belt 14. During the operation of the belt conveyor body 1 driven by the first motor 3, the first synchronous pulley 4 rotates synchronously. The first synchronous belt 8 drives the cleaning roller 5 to rotate. The fourth synchronous pulley 13, the third synchronous pulley 12, and the second synchronous belt 14 drive the transmission roller 10 to rotate while the cleaning roller 5 rotates, thus driving the conveyor belt 11. When the conveyor belt 11 runs, the scraper 17 on its surface moves forward, while the bottom of the belt conveyor body 1 moves backward. When the scraper 17 contacts the bottom of the belt conveyor body 1, the relative force enhances its scraping effect. Furthermore, the spring extension rod 16 increases the scraper's... The fit between scraper 17 and the main body 1 of the belt conveyor is ensured to guarantee the scraping effect of scraper 17. After scraping, the sweeper head 504 cleans the dust and other fine particles on the main body 1 of the belt conveyor. The sweeper head 504 can be easily removed and replaced by magnetic insertion of magnetic groove 502 and insert block 503. Under the action of torsion spring shaft, the first tensioning rod 18 will rotate downward and press the first synchronous belt 8 with tensioning wheel 19, which can tighten the first synchronous belt 8 to achieve the tensioning effect. Under the action of torsion spring shaft, the second tensioning rod 20 will rotate downward and press the second synchronous belt 14 with tensioning roller 21, which can also achieve the tensioning effect, thereby ensuring the transmission effect of the first synchronous belt 8 and the second synchronous belt 14.

[0023] Example 2: Please see Figure 1-7The embodiment differs from Example 1 in that a pair of brackets 22 are provided at the bottom of the main body 1 of the belt conveyor, and the two ends of the brackets 22 are respectively screwed and fixed to the two columns of the main body 1 of the belt conveyor. A waste frame 23 is clamped between the two brackets 22, and a water tank 24 is clamped between the two brackets 22. A guide pump 25 is screwed to the top of the water tank 24, and a corrugated telescopic pipe 26 is inserted into the output end of the guide pump 25. A lifting frame 27 is screwed to the other end of the bottom of the main body 1 of the belt conveyor, and a lifting plate 28 is slidably installed inside the lifting frame 27. Several reinforcing rods 29 are welded at equal intervals on one side of the outer wall of the lifting plate 28. A spray frame 30 is provided on one side of the outer wall of the lifting plate 28, and the spray frame 30 is screwed and fixed to the reinforcing rods 29. The other end of the corrugated telescopic pipe 26 is inserted and connected to the bottom of the spray frame 30. Several atomizing nozzles 31 are provided at equal intervals on the top of the spray frame 30, and the atomizing nozzles 31 are inclined. A screw 32 is inserted into the center, and the top end of the screw 32 is connected to the top of the inner wall of the lifting frame 27 via a bearing. A handwheel 33 is welded to the bottom end of the screw 32. The screw 32 is threaded to the lifting plate 28. Second brackets 34 are screwed to both sides of the top of the belt conveyor body 1, and second motors 35 are screwed to the second brackets 34. A sector gear 36 is welded to the telescopic end of the second motor 35. Connecting frames are screwed to both outer walls of the belt conveyor body 1. 37, and a telescopic support rod 38 is screwed onto the connecting frame 37. A limit plate 39 is screwed onto the telescopic end of the telescopic support rod 38. A drive rod 40 is welded onto the outer wall of the limit plate 39. A toothed groove 41 is opened on one side of the drive rod 40. The teeth of the sector gear 36 mesh with the toothed groove 41. A controller 42 is screwed onto the outer wall of one side of the belt conveyor body 1. The bottom of the limit plate 39 is attached to the top of the belt conveyor body 1. One end of the limit plate 39 is bent outward. The waste box 23 collects the fertilizer material scraped off by the scraper 17. The water in the water tank 24 is pumped out by the guide pump 25 and the corrugated telescopic pipe 26 and transported to the spray frame 30, and then sprayed out by the atomizing nozzle 31. The impact force of the water flow can be used to make the material detach from the belt conveyor body 1, reducing the difficulty of scraping. The position of the spray frame 30 can be adjusted by turning the handwheel 33. When the spray frame 30 is close to the bottom of the belt conveyor body 1, the impact force generated by the water flow will be enhanced, and the rinsing effect will be the best. The second motor 35 drives the sector gear 36 to swing back and forth. Under the action of the drive rod 40 and the tooth groove 41, the limiting plate 39 can be moved back and forth, thereby pushing the fertilizer material towards the center of the belt conveyor body 1 during the conveying process, avoiding the fertilizer material from deviating during the conveying process and affecting the conveying effect. The telescopic support rod 38 is used to limit the movement trajectory of the limiting plate 39. The controller 42 is used to control the first motor 3, the guide pump 25 and the second motor 35.

[0024] In use, the first motor 3, spring telescopic rod 16, guide pump 25, second motor 35, and controller 42 used in this invention are all existing mature technologies, and therefore will not be described in detail below. By pouring fertilizer production raw materials onto the belt conveyor body 1, the controller 42 starts the first motor 3, which enables the belt conveyor body 1 to run and transport the fertilizer production raw materials. During the operation of the belt conveyor body 1 driven by the first motor 3, the first synchronous pulley 4 will rotate synchronously. The first synchronous belt 8 drives the cleaning roller 5 to rotate. The fourth synchronous pulley 13, the third synchronous pulley 12, and the second synchronous belt 14 drive the transmission roller 1 when the cleaning roller 5 rotates. The conveyor belt 11 rotates, driving its operation. The scraper 17 on the conveyor belt 11 scrapes away fertilizer material adhering to the conveyor body 1. As the conveyor belt 11 runs, the scraper 17 moves forward, while the bottom of the conveyor body 1 moves backward. When the scraper 17 contacts the bottom of the conveyor body 1, the relative force enhances its scraping effect. Furthermore, the spring telescopic rod 16 increases the contact between the scraper 17 and the conveyor body 1, ensuring effective scraping. The guide pump 25 and corrugated telescopic pipe 26 extract water from the water tank 24 and transport it to the spray frame 30. Then, the water is sprayed out by the atomizing nozzle 31. The impact force of the water flow can be used to detach the raw material from the belt conveyor body 1, reducing the difficulty of scraping. The position of the spray frame 30 can be adjusted by turning the handwheel 33. When the spray frame 30 is close to the bottom of the belt conveyor body 1, the impact force generated by the water flow will be enhanced, and the rinsing effect will be the best. After scraping, the sweeping head 504 cleans the dust and other fine particles on the belt conveyor body 1. The sweeping head 504 can be easily removed and replaced by using the magnetic suction groove 502 and the plug 503. The waste box 23 can collect the fertilizer raw material scraped off by the scraper 17. Under the action of the torsion spring shaft, the first tensioning rod 18 will rotate downward and press the tensioning wheel 19. A synchronous belt 8 can tighten the first synchronous belt 8 to achieve a tensioning effect. Under the action of the torsion spring shaft, the second tensioning rod 20 will rotate downward and press the second synchronous belt 14 with the tensioning roller 21, which can also achieve a tensioning effect, thereby ensuring the transmission effect of the first synchronous belt 8 and the second synchronous belt 14. The second motor 35 drives the sector gear 36 to swing back and forth. Under the action of the drive rod 40 and the tooth groove 41, it can drive the limiting plate 39 to move back and forth, thereby pushing the fertilizer raw material towards the center of the belt conveyor body 1 during the conveying process, avoiding the fertilizer raw material from deviating during the conveying process and affecting the conveying effect. The telescopic support rod 38 is used to limit the movement trajectory of the limiting plate 39.
