DETAILED DESCRIPTION

[0039] Reference Figure 1 , an intelligent dust removal, weighing and warehousing equipment for wheat after drying, includes a protective cover 7 fixedly installed on a conveying cylinder 4, a fixed bracket 1 is fixedly installed on the end of the conveying cylinder 4 away from the protective cover 7, and a feeding bucket 2 is fixedly installed on the fixed bracket 1, the feeding bucket 2 is communicated with the conveying cylinder 4, the fixed bracket 1 is a table body with a hole in the middle, which is used to support the left side of the conveying cylinder 4 and fix the feeding bucket 2, and the end of the conveying cylinder 4 away from the fixed bracket 1 is fixedly connected with a discharge hopper 5, the feeding bucket 2 is used to feed the dried wheat into the conveying cylinder 4, and the discharge hopper 5 is used to discharge the fed wheat from the other end of the conveying cylinder 4.

[0040] A fixed leg 3 is fixedly installed at the bottom of the protective cover 7, and the conveying cylinder 4 is inclined upward from the fixed bracket 1 to the protective cover 7. Since general granaries have a certain height, or the wheat will have a certain height after being piled up in the granary, the inclined setting of the conveying cylinder 4 can transport the wheat from a low place to a high place, which is more conducive to its unloading and storage in the granary. A weighing platform 6 is installed on the input bucket 2. The weighing platform 6 is an existing table for automatic weighing, and a leakage groove is arranged on it. When transporting wheat, the staff puts the bagged wheat on the weighing platform 6, and then the wheat can be automatically weighed before entering the warehouse. After the weighing is completed, the bag is opened and the wheat is poured into the input bucket 2 for transportation.

[0041] Reference Figure 1-Figure 13, an intelligent dust removal, weighing and warehousing equipment for wheat after drying, also includes a lifting and conveying part, which is used to lift and convey the wheat. The lifting and conveying part includes a motor 8 fixedly mounted on a protective cover 7, and the output end of the motor 8 is fixedly connected to a driving rod 9, and the part of the driving rod 9 located in the conveying cylinder 4 is fixedly installed with an auger 10. When the motor 8 is working, the driving rod 9 can drive the auger 10 to rotate in the conveying cylinder 4, so that the rotation of the auger 10 can be used to lift the wheat from the input bucket 2 to the discharge bucket 5 and discharge it, thereby completing the lifting and conveying of the wheat.

[0042] The anti-blocking part is used to prevent the wheat from being blocked in the conveying cylinder 4 during the conveying process. The anti-blocking part includes a pressure chamber 11 and an anti-blocking chamber 13 respectively opened at both ends of the conveying cylinder 4. The pressure chamber 11 is located at one end of the conveying cylinder 4 close to the motor 8. The end of the driving rod 9 located in the pressure chamber 11 is fixedly installed with a fan blade 12. When the fan blade 12 is working, the pressure chamber 11 generates negative pressure at one end close to the motor 8 and positive pressure at the other end. The anti-blocking chamber 13 is fixedly installed with a filter plate 18 at one end close to the pressure chamber 11. The driving rod 9 is hollow, and the end of the driving rod 9 away from the motor 8 is connected to the anti-blocking chamber 13. The end of the driving rod 9 close to the motor 8 is sealed. The part of the driving rod 9 located in the conveying cylinder 4 is evenly provided with a plurality of air injection holes 19. An air delivery component is installed between the end of the pressure chamber 11 close to the anti-blocking chamber 13 and the anti-blocking chamber 13. The air delivery component is composed of an air inlet pipe 14, an air outlet pipe 15, two connection boxes 16 and two connecting pipes 17.

[0043] The air inlet pipe 14 is fixedly connected to the left side of the anti-blocking chamber 13, and the air outlet pipe 15 is fixedly connected to the end of the pressure chamber 11 away from the motor 8. The two connecting boxes 16 are fixedly connected to the air inlet pipe 14 and the air outlet pipe 15 respectively, and the two connecting pipes 17 are connected between the two connecting boxes 16. When the driving rod 9 is working, the fan blades 12 are driven to rotate. At this time, a positive pressure is generated at the end of the pressure chamber 11 away from the motor 8, and the gas is discharged through the air outlet pipe 15, and enters the anti-blocking chamber 13 from the air inlet pipe 14 through the connecting box 16 and the connecting pipe 17. The gas entering the anti-blocking chamber 13 passes through the filter plate 18 to blow the wheat that falls from the input bucket 2 into the conveying cylinder 4 to prevent the wheat from accumulating and clogging under the input bucket 2. At the same time, some gas enters the hollow driving rod 9 and is ejected outward from a plurality of air jet holes 19, so that the wheat can be blown during the spiral conveying of wheat. The air flow change is used to make the dust escape from the wheat faster, which is convenient for the subsequent collection and treatment of the dust, and the dust removal rate can be effectively improved.

[0044] The dust suction part is used to remove dust from the wheat during the transportation process. The dust suction part includes a dust suction cover 20 fixedly installed on the side wall of the conveying cylinder 4. Two connecting pipes 23 are fixedly connected to the side wall of the dust suction cover 20. The connecting pipes 23 are connected to the dust suction cover 20 through a straight pipe, and an exhaust pipe 22 is fixedly connected between the two connecting pipes 23 and the end of the pressure chamber 11 close to the motor 8. A plurality of dust suction holes 21 communicating with the dust suction cover 20 are provided on the side wall of the conveying cylinder 4. Filters are fixedly installed on the ends of the straight pipes and the dust suction holes 21 close to the dust suction cover 20. When the driving rod 9 rotates, negative pressure is generated at the end of the pressure chamber 11 close to the motor 8. At this time, negative pressure can be generated in the two connecting pipes 23 through the two exhaust pipes 22, and then negative pressure is generated in the dust suction cover 20. The dust that escapes from the wheat is collected into the dust suction cover 20 by the dust suction holes 21, so as to separate the wheat from the dust.

[0045] A dust scraping assembly and a dust exhaust assembly matched with the dust scraping assembly are installed on the dust suction sleeve 20. The dust scraping assembly is used to scrape the dust sucked into the dust suction sleeve 20 and discharge it through the dust exhaust assembly. The dust scraping assembly consists of a swivel 24, two scrapers 25 and two protruding plates 37. The swivel 24 is sealed and rotatably connected to the end of the dust suction sleeve 20 close to the protective cover 7. The two scrapers 25 are fixedly installed at the end of the swivel 24 away from the protective cover 7, and the two scrapers 25 are both in contact with the inner wall of the dust suction sleeve 20. The two protruding plates 37 are respectively fixedly installed at the ends of the two scrapers 25 away from the conveying cylinder 4. When the swivel 24 rotates, the dust sucked into the dust suction sleeve 20 can be scraped by the two scrapers 25, and the filter screen at the straight pipe and the dust suction hole 21 can also be scraped and cleaned.

[0046] The dust exhaust assembly consists of a dust exhaust port 26, an arcuate groove 27, an arcuate plate 28 and a dust collecting box 29. The dust exhaust port 26 is provided on the dust collection sleeve 20, and the arcuate groove 27 is provided on the side wall of the dust exhaust port 26. The arcuate plate 28 is sealingly and slidably installed in the arcuate groove 27, and the size of the arcuate plate 28 is larger than the size of the dust exhaust port 26. A plurality of springs are installed between the arcuate plate 28 and the arcuate groove 27. One end of the arcuate plate 28 close to the protruding plate 37 is a magnet, and the protruding plate 37 is made of magnetic material. The dust collecting box 29 is fixedly installed on the side wall of the dust collection sleeve 20, and the dust collecting box 29 corresponds to the position of the dust exhaust port 26. When the scraper 25 rotates in the dust collection sleeve 20 so that the protruding plate 37 corresponds to the position of the arcuate plate 28, the continued rotation of the scraper 25 will be magnetically moved between the protruding plate 37 and the arcuate plate 28. When the scraper 25 continues to rotate and the protruding plate 37 is separated from the arc plate 28, the elastic force of the spring will cause the arc plate 28 to automatically reset and realize the re-closing and sealing of the dust outlet 26.

[0047] A plurality of dust suction holes 21 are symmetrically arranged on the conveying cylinder 4 in an upper and lower manner. A baffle plate matching the corresponding plurality of dust suction holes 21 is fixedly installed on one side of the protruding plate 37 close to the conveying cylinder 4. Through this design, the baffle plate can be used to block the dust suction holes 21 when the dust sucked into the dust suction sleeve 20 is discharged. At this time, no additional gas flow will be generated in the dust suction sleeve 20, thereby preventing the dust therein from falling through the dust discharge port 26 better. At the same time, the negative pressure at the dust suction hole 21 disappears. At this time, the rotation of the auger 10 will also cause the dust suction hole 21 to be swept and cleaned near the conveying cylinder 4, thereby further improving the dredging effect of the dust suction hole 21 and avoiding blockage at the dust suction hole 21.

[0048] A discharge groove is provided at one end of the dust box 29 away from the protective cover 7, and a sealing plate is sealed on the discharge groove. After a certain batch of wheat is transported, the sealing plate can be removed and the dust in the dust box 29 can be discharged. The dust is weighed to obtain the dust content of the wheat, which is convenient for data statistics.

[0049] A driving assembly that cooperates with the dust scraping assembly is installed on the driving rod 9. The driving assembly is used to make the dust collection part intermittent during the conveying process. The driving assembly consists of a fixed gear ring 30, a rotating rod 31, a fixed gear 32, a connecting shaft 33, a connecting gear 34, a belt transmission structure 35 and an incomplete gear 36. The fixed gear ring 30 is fixedly installed on the side wall of the rotating ring 24 outside the dust collection sleeve 20, the rotating rod 31 is rotatably connected to the protective cover 7, the fixed gear 32 is fixedly installed on the rotating rod 31, and the fixed gear 32 is meshed with the fixed gear ring 30, the connecting shaft 33 is rotatably installed on the conveying cylinder 4, and the belt transmission structure 35 is installed on the connecting shaft 33. Between the connecting shaft 33 and the rotating rod 31, the connecting gear 34 is fixedly mounted on the connecting shaft 33, and the incomplete gear 36 is fixedly mounted on the driving rod 9, and the incomplete gear 36 is meshed with the connecting gear 34. When the driving rod 9 rotates, the meshing effect of the incomplete gear 36 and the connecting gear 34 will drive the connecting shaft 33 to rotate intermittently, and then the rotating rod 31 will rotate at the same time under the action of the belt transmission structure 35. At this time, the meshing of the fixed gear 32 and the fixed gear ring 30 will cause the rotating ring 24 to rotate, so that the scraper 25 rotates in the dust collection sleeve 20 to achieve dust scraping and dust discharge processing, without the need to set up an additional power component.

[0050] The transmission ratio of the incomplete gear 36 to the connecting gear 34 is 1:2, the transmission ratio of the fixed gear 32 to the fixed gear ring 30 is 1:4, and the belt transmission structure 35 is composed of a pulley 1, a pulley 2 and a belt. The pulley 1 is fixedly mounted on the connecting shaft 33, the pulley 2 is fixedly mounted on the rotating rod 31, and the belt is mounted between the pulley 1 and the pulley 2. The transmission ratio of the pulley 1 to the pulley 2 is 2:1. The design advantage of the transmission ratio here is that when the driving rod 9 rotates one circle, the connecting shaft 33 can be driven to rotate. 180°, the design of the belt transmission structure 35 enables the rotating rod 31 to rotate 360°, and then the rotating ring 24 is rotated 90° under the cooperation of the fixed gear 32 and the fixed gear ring 30. Since the two scrapers 25 on the rotating ring 24 are symmetrically arranged, when the driving rod 9 rotates one circle, the scraper 25 rotates 90° in the dust suction sleeve 20. Then, it can be achieved that the scraper 25 will stop for a certain period of time every time it rotates 90° in the dust suction sleeve 20. Through this design, the dust suction effect and automatic dust removal effect can be improved.

[0051] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
