Description

Technical Field

[0001] This utility model relates to the field of shelling machines, specifically to a high-efficiency shelling machine. Background Technology

[0002] Cottonseed hulling machines are important equipment used for hulling cottonseed and other materials. Their performance directly affects the efficiency and quality of cottonseed hulling and they occupy a key position in the cottonseed processing industry.

[0003] Existing hulling machines cannot effectively screen cottonseeds of different sizes, resulting in poor hulling accuracy. Furthermore, the gap between the crushing rollers is difficult to adjust flexibly according to the actual size of the cottonseeds, easily causing them to be crushed. The unreasonable structural design of the crushing rollers leads to frequent rigid collisions between materials and components, resulting in more broken cottonseed kernels and affecting their integrity. Changing the driven roller is cumbersome, making it difficult to quickly replace the appropriate crushing roller for different material types, thus limiting the applicability of the hulling machine. Therefore, those skilled in the art have provided a high-efficiency hulling machine to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned shortcomings and provide a high-efficiency hulling machine. This solves the problems of existing technologies, which cannot effectively screen cottonseeds of different sizes to be hulled, resulting in poor hulling accuracy, inconvenient adjustment of the gap between the crushing rollers, easy damage to cottonseeds, and loss of integrity. Furthermore, it is difficult to quickly replace the appropriate crushing rollers according to different types of materials.

[0005] The objective of this utility model is achieved through the following means:

[0006] A high-efficiency shelling machine includes a housing with a feed inlet at the top. A sieve plate is obliquely inserted into the feed inlet. A feeder is located below the sieve plate, and a magnetic separation unit is located below the feeder. A drive roller is located below the magnetic separation unit. One end of the drive roller, located outside the housing, is connected to a drive unit connecting assembly. A driven roller is located on one side of the drive roller. A limit frame is installed on the outer wall of the housing, and a buckle is located inside the limit frame. A connecting plate is located on one side of the buckle. A first screw is rotatably engaged with the connecting plate facing the buckle, and a second screw is rotatably engaged with the connecting plate on the other side of the connecting plate. A screw hole is provided on the side of the buckle facing the connecting plate.

[0007] Furthermore, a discharge port is provided on one side of the feed inlet, and the sieve plate is slidably inserted into the inner wall of the feed inlet. The sieve plate can be replaced according to the size of the cottonseeds to be hulled, so that qualified products fall downwards and unqualified products are discharged from the discharge port on one side of the feed inlet.

[0008] Furthermore, movable holes are provided on the front and rear walls of the housing. The two ends of the driven roller are slidably inserted into the movable holes, and one end of the driven roller is inserted into the buckle. After disconnecting the connection between the first screw and the buckle, the buckle can be removed, thereby completing the replacement of the driven roller. A crushing roller suitable for the material can be replaced according to the type of material.

[0009] Furthermore, the first screw is threadedly connected to the screw hole on one side of the buckle, and the second screw is threadedly sleeved to the side wall of the limiting frame. When the first screw is connected to the buckle, rotating the second screw can move the driven roller inserted in the buckle, thereby adjusting the gap between the driven roller and the driving roller. When crushing cottonseed material, the gap between the crushing rollers can be adjusted according to the specifications of the cottonseed to avoid crushing the cottonseed.

[0010] Furthermore, a discharge port is provided on the bottom side of the shell.

[0011] The beneficial effects of this invention are as follows: the screen plate inside the feed inlet at the top of the shell is replaceable, allowing for screening based on the size of the cottonseeds to be shelled, thus improving shelling accuracy; qualified products are evenly distributed by the feeder, avoiding uneven material distribution; when the material passes through the magnetic separation unit, iron impurities are adsorbed, preventing iron damage to the crushing rollers and extending their service life; by rotating the first and second screws, the gap between the driven roller and the driving roller can be adjusted, allowing for adjustment of the crushing roller gap according to the cottonseed specifications, preventing cottonseed damage and improving the integrity of the cottonseed kernels; after disconnecting the first screw from the buckle connection, the buckle can be removed, facilitating the replacement of the driven roller, and allowing for the replacement of suitable crushing rollers according to the type of material, thus improving the applicability of the shelling machine.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0017] In this embodiment, refer to Figures 1-3 The high-efficiency cottonseed shelling machine includes a housing 1, with a feed inlet 2 at the top of the housing 1. A sieve plate 3 is obliquely inserted into the feed inlet 2, and a discharge outlet 201 is located on one side of the feed inlet 2. The sieve plate 3 is slidably inserted into the inner wall of the feed inlet 2. The sieve plate 3 can be replaced according to the size of the cottonseeds to be shelled, so that qualified products fall downwards, and unqualified products are discharged from the discharge outlet 201 on the side of the feed inlet 2. A feeder 4 is arranged below the sieve plate 3, and a magnetic separation unit 5 is arranged below the feeder 4. A main feeder is arranged below the magnetic separation unit 5. The active roller 6 is connected to a drive unit connection assembly 7 at one end outside the housing 1. A driven roller 8 is provided on one side of the active roller 6. A limit frame 9 is installed on the outer wall of the housing 1. A buckle 10 is provided inside the limit frame 9. A connecting plate 12 is provided on one side of the buckle 10. The first screw 13 is rotatably engaged with the side of the connecting plate 12 facing the buckle 10. The second screw 14 is rotatably engaged with the other side of the connecting plate 12. A screw hole 11 is opened on the side of the buckle 10 facing the connecting plate 12. A discharge port is opened on the bottom side of the housing 1.

[0018] Movable holes 15 are provided on the front and rear walls of the housing 1. The two ends of the driven roller 8 are slidably inserted into the movable holes 15, and one end of the driven roller 8 is inserted into the buckle 10. After disconnecting the connection between the first screw 13 and the buckle 10, the buckle 10 can be removed, thereby completing the replacement of the driven roller 8. The crushing roller suitable for the material can be replaced according to the type of material. The first screw 13 is threadedly connected to the screw hole 11 on one side of the buckle 10, and the second screw 14 is threadedly sleeved to the side wall of the limit frame 9. When the first screw 13 is connected to the buckle 10, rotating the second screw 14 can move the driven roller 8 inserted in the buckle 10, thereby adjusting the gap between the driven roller 8 and the driving roller 6. When crushing cottonseed material, the gap between the crushing rollers can be adjusted according to the specifications of the cottonseed to avoid crushing the cottonseed.

[0019] The working principle of this device is as follows: A feed inlet 2 is provided on the upper part of the shell 1. A sieve plate 3 is inserted obliquely inside the feed inlet 2. The sieve plate 3 can be replaced according to the size of the cottonseeds to be shelled, so that qualified products fall downwards and unqualified products are discharged from the discharge outlet 201 on one side of the feed inlet 2.

[0020] As the qualified product falls downwards, it is evenly distributed when passing through the feeder 4 to avoid uneven material distribution. Then, as the material falls, it passes through the magnetic separation unit 5. When passing through the magnetic separation unit 5, the iron impurities in the material are adsorbed, which can prevent the iron impurities in the material from damaging the crushing roller below. Finally, the material falls between the active roller 6 and the driven roller 8 for crushing and peeling.

[0021] Furthermore, a drive unit connection assembly 7 is connected to one end of the drive roller 6 inside the housing 1, which can be driven by an external drive device. Movable holes 15 are provided on the side walls at both ends of the driven roller 8. A limit frame 9 is installed on the front side of the housing 1. A buckle 10 is provided inside the limit frame 9. A connecting plate 12 is provided on one side of the buckle 10. A first screw 13 is rotatably connected to the side of the connecting plate 12 facing the buckle 10. The first screw 13 is threadedly connected to the screw hole 11 on one side of the buckle 10. A second screw is rotatably engaged at the end of the connecting plate 12 away from the buckle 10. The screw 14 and the second screw 14 are threadedly connected to one side wall of the limiting frame 9. After the first screw 13 is connected to the buckle 10, rotating the second screw 14 can move the driven roller 8 inserted in the buckle 10, thereby adjusting the gap between the driven roller 8 and the driving roller 6. When crushing cottonseed, the gap between the crushing rollers can be adjusted according to the specifications of the cottonseed to avoid crushing the cottonseed. Furthermore, the driving roller 6 and the driven roller 8 are covered with a material that reduces the diameter of the yarn path and is wear-resistant, which can reduce the breakage of cottonseed kernels caused by rigid collisions between materials and components.

[0022] Furthermore, after disconnecting the connection between the first screw 13 and the buckle 10, the buckle 10 can be removed, thereby completing the replacement of the driven roller 8. A crushing roller suitable for the material can be replaced according to the type of material.

[0023] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
