Description

Technical Field

[0001] The invention belongs to the technical field related to material unloading, and specifically discloses a balanced material unloading device for a hopper used in an agricultural product production line. Background Art

[0002] Agricultural products refer to primary products derived from planting, forestry, animal husbandry and fishery, that is, plants, animals, microorganisms and their products obtained in agricultural activities, such as rice, sorghum, peanuts, corn, wheat, soybeans and local specialties of various regions.

[0003] Most existing agricultural product production lines use hoppers with internal conical surfaces to guide material discharge, and the diameter of the feed opening is small. When storing agricultural products containing moisture (such as wheat and rice), the materials tend to aggregate and stick together due to their own moisture, forming agglomerates or arch structures. As a result, only the center of the material falls quickly during discharge, while the edge material is retained. Frequent manual intervention is required to clear the feed opening, resulting in uneven material discharge. The existing Chinese patent publication number CN118850791A discloses a balanced feeding device for a rice processing production line using a hopper, comprising a base, two support plates symmetrically fixed on the base, side plates fixed on both support plates, two rollers rotatably arranged between the two side plates, the two rollers rotatably arranged at the two ends of the two side plates via shafts, and conveyor belts sleeved on the two rollers, a drying chamber fixed on the two side plates, the conveyor belts slidingly passing through the drying chamber, openings corresponding to the conveyor belts are provided on both side walls of the drying chamber, a motor is fixed on one side plate, one end of the shaft rotates through the side plate and is fixedly connected to the output end of the motor, and a back plate is also fixed on the base. The present invention can evenly lay the rice on the conveyor belt, and deliver the rice to the drying chamber for drying via the conveyor belt, thereby greatly improving the rice drying effect; The application proposed installing a drying chamber above a conveyor belt to dry rice containing moisture, achieving the goal of reducing moisture. However, numerous problems arose during actual use. However, the dryer only briefly blasted the surface of the material, preventing the hot air from penetrating deeply into the interior. Consequently, moisture was not completely evaporated, and the material remained lumpy in the hopper due to moisture. This did not fundamentally address the unloading problem. Furthermore, the traditional hopper relied on manual adjustment of the unloading speed and could not dynamically adjust to material characteristics (such as moisture content and particle size), resulting in poor adaptability. Therefore, improvements were needed. Summary of the Invention

DETAILED DESCRIPTION

[0018] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] like Figures 1-9 The illustrated embodiment of a balanced feeding device for a hopper of an agricultural product production line comprises a frame 1 and a conveyor 8. A hopper 2 is mounted above the interior of the frame 1. A material leveling bin 14 is connected to and installed below the interior of the hopper 2. A blocking mechanism is provided on one side of the interior of the material leveling bin 14. The conveyor 8 is mounted inside the frame 1 and below the material leveling bin 14. A bracket 3 is mounted on the upper edge of the hopper 2. A heat conduction diversion mechanism is provided in the middle of the bracket 3. Vibrating material distribution mechanisms are provided on both sides of the interior of the hopper 2 and near the bottom. A temperature sensor 36 is installed at the front end of the interior of the hopper 2. Baffles 9 are provided on both sides of the outer wall of the conveyor 8. The baffles 9 can prevent material from spilling and ensure that the conveyor 8 is relatively fully loaded. The heat conduction diversion mechanism is used to evenly disperse the hot air inside the hopper 2 and guide the air to penetrate around the agricultural products from which the air is discharged, thereby accelerating the loss of moisture from the agricultural products.

[0021] The sealing mechanism includes a sealing plate 16 that is slidably inserted into one side of the inner side of the material mixing bin 14. A connecting plate 35 is fixedly provided on the upper edge of one side of the sealing plate 16. A hydraulic cylinder 13 is provided on one side of the connecting plate 35. The outside of the hydraulic cylinder 13 is mounted on one side of the inner side of the frame 1 through a fixed plate 12. When unloading is required, the hydraulic cylinder 13 contracts and drives the sealing plate 16 to move to one end, exposing the unloading port of the material mixing bin 14. When unloading stops, the hydraulic cylinder 13 extends and pushes the sealing plate 16 to completely close the material mixing bin 14.

[0022] The heat conduction diversion mechanism includes a cylinder 4 vertically inserted in the middle of the bracket 3, a connecting pipe 26 is fixedly provided inside the cylinder 4, and a nozzle 28 is installed on the outside of the connecting pipe 26 at equal distances in the vertical direction, and the air outlet of the nozzle 28 is set to one side and downward, and a card shell 19 is set on the outside of the nozzle 28. One end of the card shell 19 extends out of the outside of the cylinder 4, and a flow port is opened inside the card shell 19. The upper end of the connecting pipe 26 is connected to the air supply pipe 5, and the end of the air supply pipe 5 away from the connecting pipe 26 is connected to the dryer 6. The dryer 6 is fixed to the outer wall of the hopper 2 by a base 7 provided on the outside. A wave guide 20 is provided on the outside of the cylinder 4 and below the card shell 19, and a wave slide cavity is opened inside the wave guide 20; The connecting pipe 26 vertically passes through the center of the hopper 2, and the nozzles 28 are evenly distributed vertically on the connecting pipe 26 to cover different material layer depths. The outlet direction of the nozzle 28 is set at a 45-degree angle to the horizontal to cover the interior of the hopper 2. When the dryer 6 is started, the hot air is transported to the interior of the connecting pipe 26 through the air supply pipe 5. Finally, the hot air is evenly sprayed on the interior of the wave guide 20 by multiple nozzles 28. The hot air hits the wave slide cavity to form turbulence, expands the hot air diffusion area, and improves the hot air utilization rate; The housing 19 can protect the nozzle 28 and guide the air flow to spray in a directional manner.

[0023] The vibrating material distributing mechanism includes a screw rod 17 rotatably arranged on one side of the interior of the hopper 2 and located below. The external thread of the screw rod 17 is connected to a slide rod 31. A rolling member is arranged inside one end of the slide rod 31. The rolling member includes a guide wheel 32. The guide wheel 32 is rotatably mounted on one end of the interior of the slide rod 31. A clamping seat 25 is provided on the inner wall of the hopper 2. A rotating shaft 27 is inserted into the two sets of clamping seats 25. A support rod 15 is rotatably sleeved on the outer side of the rotating shaft 27. The bottom end of the slide rod 31 is slidably fitted with the inner wall of the hopper 2. A rotating drum 29 is rotatably arranged on the upper part of one side of the slide rod 31. A material-diverting member is arranged on the outer side of the rotating drum 29. The material-diverting member includes a plurality of rubber columns 30 provided on the outer surface of the rotating drum 29, and a convex ball 34 is provided at one end of the plurality of rubber columns 30. Rolling sleeves 33 are provided on both sides of the outer side of the rotating drum 29 away from the rubber columns 30. The rolling sleeves 33 are in rolling contact with the inner wall of the hopper 2. Both ends of the screw rod 17 extend to the outside of the hopper 2. A fixing frame 11 and a clamping frame 37 are respectively provided at the position of the screw rod 17 on the outer wall of the hopper 2. Both ends of the screw rod 17 extend to the inside of the fixing frame 11 and the clamping frame 37. A motor 10 is fixedly installed on the outside of the fixing frame 11, and the output shaft of the motor 10 is connected to one end of the screw rod 17. A diverter frame 18 is fixedly provided on one side of the support rod 15. Separators 21 are installed on the outer surface of the diverter frame 18 at equal intervals in the horizontal direction. Dividing slices 23 are provided at equal intervals in the horizontal direction at the lower end of the diverter frame 18. A bottom rod 22 is provided at the bottom end of the plurality of dividing slices 23. V-shaped guide seats 24 are provided at equal intervals in the horizontal direction at the rear end of the outer wall of the bottom rod 22. The guide wheel 32 is in rolling contact with the guide seat 24. When the motor 10 drives the screw rod 17 to rotate, the slide rod 31 moves laterally along the outside of the screw rod 17, and the guide wheel 32 at the end of the slide rod 31 rolls along the outer surface of the V-shaped guide seat 24, forcing the support rod 15 to swing around the rotating shaft 27. The diverter rack 18 swings synchronously with the support rod 15, and the separator 21 can shuttle longitudinally among the wheat. When the wheat is discharged, the disturbance is accelerated, causing the wheat to slide more quickly onto the inner wall of the hopper 2; When the drum 29 moves with the slide bar 31, the rubber column 30 and the convex ball 34 can flexibly remove the wheat adhering to the inner wall of the hopper 2, while the roller sleeve 33 can reduce the friction. It should be noted that when the dividing slices 23 and the dividing slices 21 of the device swing in conjunction with the diverter rack 18, the material inside the hopper 2 is in a discharge state, and during the wheat storage process, the dividing slices 23 and the dividing slices 21 occupy a small area, so they will not affect the storage space inside the hopper 2.

[0024] Since the outer surface of the wheat is relatively smooth, during the feeding process, the resistance will not affect the motor 10 driving the screw rod 17 to rotate and drive the slide rod 31 to move inside the hopper 2.

[0025] Working Principle: When in use, agricultural products such as wheat are added from the top of the hopper 2 and accumulated inside the hopper 2. At this time, the dryer 6 is started, and hot air is delivered to the connecting pipe 26 through the air supply pipe 5. The hot air is sprayed obliquely downward through the nozzle 28, penetrates the material layer, and hits the wave guide 20. The wave sliding cavity set inside the wave guide 20 can interrupt the hot air flow, forcing the hot air to flow through the gaps between the materials, accelerating water evaporation and expanding the heat conduction area. When material is to be unloaded, the motor 10 drives the screw 17 to rotate, the slide bar 31 moves laterally along the inner wall of the hopper 2, the guide wheel 32 rolls on the outer surface of the V-shaped guide seat 24, driving the diverter frame 18 to swing, and the separator 21 is inserted into the material layer to break the adhesion of the material, while the equally spaced dividing slices 23 disturb the material near the bottom of the hopper 2, urging it to fall and improving the uniformity of the unloading. When the slide bar 31 moves, it also drives the rotating drum 29 to rotate, and the rubber column 30 and the convex ball 34 continuously push away the material adhering to the inner wall of the hopper 2 to prevent bridging and blockage. At the same time, the hydraulic cylinder 13 drives the sealing plate 16 to one end to leave the discharge port inside the material mixing bin 14, allowing the material to fall from the inside of the material mixing bin 14 onto the conveyor 8, and the conveyor 8 transports the material to the next process.

[0026] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the invention as claimed.
