Description

Technical Field

[0001] This utility model belongs to the technical field of grain physical separation equipment, specifically relating to a grain pest separation device. Background Technology

[0002] After harvest, grains are easily affected by pests during storage, which can negatively impact their quality. Specifically, when grains are eaten by pests, more broken grains are produced, reducing the germination rate of seeds. In addition, the silk produced by pests can cause grains to clump together, and insect excrement, dead insects, and foul-smelling liquids secreted by some pests can contaminate the grains, even producing toxins or causing them to heat up and mold. Therefore, it is necessary to carry out pest control operations on harvested grains. Pest control after harvesting grains can also reduce storage losses, maintain quality, prevent secondary pollution, and improve economic efficiency. It is an indispensable part of grain storage and distribution.

[0003] Currently, methods for controlling stored grain pests include mechanical and chemical methods. Mechanical methods include winnowing, windmilling, and sieves, but these methods have low efficiency and incomplete pest control. Chemical methods use insecticides, but insecticides are toxic to humans and animals, and long-term use inevitably poses safety concerns. Therefore, there is an urgent need to research a safe and efficient method for controlling grain pests. Utility Model Content

Therefore, they should not be construed as limitations on this application.

[0038] The features and performance of this application will be further described in detail below with reference to the embodiments.

[0039] A grain pest separation device, such as Figure 1-6 As shown, it includes: a feed inlet 100, a discharge device 200, a material conveying device 300, a roller 400, and a collection device 500.

[0040] Specifically, the feed inlet 100 is funnel-shaped, wider at the top and narrower at the bottom, with both the top and bottom being hollow. The feeding device 200 includes a feeding box 201, the top of which is connected to the feed inlet 100; a first drive shaft 202 is arranged horizontally in the feeding box 201, and first spiral blades 203 in opposite directions are arranged on the first drive shaft 202 from the center to both ends; seven holes 204 are equidistantly arranged horizontally at the bottom of the feeding box 201, these seven holes 204 are located directly below the first drive shaft 202; a conveying pipe 205 is connected below each hole 204; one end of the first drive shaft 202 is fixedly connected to the output end of the first motor 600; a rotatably connected partition 206 is provided at the connection between each conveying pipe 205 and the corresponding hole 204. The feed inlet 100 is located above the feeding box 201 and is connected to the grain conveyor.

[0041] The material conveying device 300 includes seven material conveying boxes 301. The top of each material conveying box 301 is connected to a conveying pipe 205. Each material conveying box 301 has an opening on its side, which is connected to a roller 400. A second drive shaft 302 is arranged in the material conveying box 301 in a transverse direction. A second spiral blade 303 is arranged on the second drive shaft.

[0042] There are seven rollers 400, arranged in two stacked layers, with three rollers 400 on the upper layer and four rollers 400 on the lower layer. The rollers 400 on the upper layer are staggered with those on the lower layer. Each roller 400 includes a roller wall 402 with mesh openings and a third drive shaft 401 axially arranged inside the roller wall. The third drive shaft 401 is fixedly connected to and rotates synchronously with the second drive shaft 302. The other end of the third drive shaft 401 is fixedly connected to the output end of the second motor 700. The roller wall 402... The roller wall 402 is fixedly connected to the third drive shaft 401 via a bracket 403. The roller wall 402 is a perforated metal mesh with holes of 1.8 mm in diameter. A baffle 404 is axially arranged on the inner side of the roller wall 402. The baffles 404 are spaced apart and evenly distributed on the roller wall 402. The height of the baffle 404 does not exceed 1 / 4 of the diameter of the roller 400. Small holes of 10 mm in diameter are provided on the baffles 404. All seven rollers 400 are placed at an angle, and the angle between the rollers and the ground is adjustable; in this embodiment, the angle is 6°. The collecting device 500 is located below the rollers 400.

[0043] Specific working principle: When grain enters the feeding box 201 of the feeding device 200 from the feed inlet 100, the first motor 600 drives the first drive shaft 202 to rotate. Since the first drive shaft 202 has first spiral blades 203 in opposite directions on its left and right sides, the grain in the feeding box 201 will be moved to both ends of the first drive shaft 202 by the first spiral blades 203 and fall into the seven holes 204 at the bottom of the feeding box 201. The partition 206, which is rotatably connected to the connection between the hole 204 and the inner part of the conveying pipe 205, can be manually set to adjust the rotation angle to adjust the opening size of the conveying pipe 205 so that the grain can fall evenly into the seven conveying pipes 205.

[0044] Grains enter the material conveying box 301 of the material conveying device 300 through the conveying pipe 205. The second motor 700 starts and drives the third drive shaft 401 and the second drive shaft 302 to rotate simultaneously. The rotation of the second drive shaft 302 can push the grains into the drum 400 by the second spiral blade 303.

[0045] The rotation of the third drive shaft 401 also drives the drum wall 402 to rotate via the bracket 403, thus causing the drum 400 to rotate. The grain will roll inside the drum 400 and be lifted by the baffle 404, accelerating the separation from the pests. The pests will fall from the small holes on the drum wall 402 into the collection device 500. Once the collection device 500 has collected enough pests, it can be disassembled and removed. Since each drum 400 is at a certain angle to the ground and is tilted downwards, the grain after pest removal will automatically flow out from the other end of the drum under the action of gravity, and can be collected in a container or enter the next grain processing step.

[0046] In summary, this utility model provides a grain pest separation device. Through the reasonable arrangement of the inlet, feeding device, material conveying device, and roller, it has a compact structure, is easy to arrange and install, can effectively screen out pests from grains, has high efficiency, and can process large quantities of grains.

[0047] The above embodiments are only used to illustrate the design concept and features of this utility model, and their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. The protection scope of this utility model is not limited to the above embodiments. Therefore, all equivalent changes, optimizations or modifications made based on the principles and design ideas disclosed in this utility model are within the protection scope of this utility model.
