[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-3 This utility model provides a technical solution: a grain processing anti-clogging peeling machine, including a machine body 1, a feeding cylinder 2, and a hopper 4. The feeding cylinder 2 is installed in the middle of the top surface of the machine body 1, and the hopper 4 is fixed to the top of the feeding cylinder 2. The top and bottom of the feeding cylinder 2 are respectively provided with through holes 12. The inside of the feeding cylinder 2 is rotatably connected to a metering cylinder 8 through a bearing. The surface of the metering cylinder 8 is evenly provided with a plurality of metering grooves 9, which can be used for metered feeding. The surface of the metering cylinder 8 and between two adjacent metering grooves 9 are provided with a movable groove 10. A pusher block 11 is movably installed in the movable groove 10. After the pusher block 11 is pushed out, it can lift the material to avoid the problem of material jamming. The inner wall of the metering cylinder 8 is provided with an annular groove communicating with the movable groove 10. The inside of the hopper is rotatably installed with a lever 19. The surface of the lever 19 is fixedly installed with a lever plate 20. After the lever 19 rotates, it moves the material in the hopper 4 through the lever plate 20 to prevent arching and bridging.
[0022] In a further improvement, a synchronization plate 5 is installed at the front end of the feeding cylinder 2, and a motor 6 is fixedly connected to the outer wall of the synchronization plate 5. A transmission shaft 7 is connected to the power output end of the motor 6. The end of the transmission shaft 7 extends into the inside of the feeding cylinder 2 and is embedded and connected to the shaft end of the metering cylinder 8. The motor 6 drives the transmission shaft 7 to rotate, and the transmission shaft 7 drives the metering cylinder 8 to rotate.
[0023] Further improvements include a cover plate 15 installed at the rear end of the feeding cylinder 2, a fixing rod 16 connected to the middle of the side wall of the cover plate 15, an eccentric disk 13 installed on the surface of the fixing rod 16, the eccentric disk 13 extending into the annular groove, a fixing plate 3 installed at the rear end of the side wall of the feeding cylinder 2, and the fixing plate 3 and the cover plate 15 are fixedly connected by bolts. During the rotation of the metering cylinder 8, the eccentric disk 13 pushes the push block 11 to move.
[0024] Further improvements include a push groove 17 on the inner wall of the push block 11, which corresponds to the annular groove. Springs 18 are installed at both ends of the bottom of the push block 11, and the ends of the springs 18 are fixedly connected to the inside of the movable groove 10. After the push block 11 has been displaced, it is reset by the springs 18.
[0025] In a further improvement, both the lever 19 and the drive shaft 7 are equipped with synchronous pulleys 22 on their surfaces and inside the synchronous plate 5. The two synchronous pulleys 22 are connected by a synchronous chain 21. When the motor 6 rotates, the lever 19 is driven to rotate through the synchronous chain 21 and the synchronous belt.
[0026] Further improvements include a base plate 14 bolted to the inside of the metering tank 9, allowing for metering adjustment by replacing the base plate 14 with one of different thicknesses.
[0027] Working principle: Motor 6 drives transmission shaft 7 to rotate metering cylinder 8. When metering trough 9 rotates with cylinder body to the bottom through hole 12 of hopper 4, grain falls into metering trough 9. When metering trough 9 rotates to the bottom through hole 12 of feed cylinder 2, grain falls precisely into peeling mechanism of machine body 1 under gravity, realizing volumetric metering. When metering cylinder 8 rotates, its inner wall annular groove moves relative to fixed eccentric disk 13. When the protrusion of eccentric disk 13 is embedded in the push groove 17 of push block 11, it pushes push block 11 outward along movable groove 10, forcibly removing grain stuck at the lower end of cylinder. After eccentric disk 13 disengages, spring 18 pulls push block 11 to reset. When transmission shaft 7 rotates, it drives lever 19 to rotate through synchronous wheel 22 and synchronous chain 21. Lever plate 20 on lever 19 rotates continuously in hopper 4, breaking the "bridging" structure formed by static friction of grain, ensuring that grain flows evenly into metering trough 9. Remove the bottom plate 14 inside the metering trough 9 and replace it with a thicker / thinner bottom plate 14 to increase or decrease the effective volume of the metering trough 9 to adapt to the processing needs of grains with different particle sizes.
[0028] The components of this utility model are: 1. machine body; 2. feeding cylinder; 3. fixed plate; 4. hopper; 5. synchronization plate; 6. motor; 7. transmission shaft; 8. metering cylinder; 9. metering groove; 10. movable groove; 11. push block; 12. through hole; 13. eccentric disc; 14. base plate; 15. cover plate; 16. fixed rod; 17. push groove; 18. spring; 19. lever; 20. lever plate; 21. synchronization chain; 22. synchronization pulley. All components are general standard parts or parts known to those skilled in the art, and their structure and principles are readily understood by those skilled in the art. According to technical manuals or conventional experimental methods, the problem solved by this invention is that in existing grain processing dehulling machines, grain easily gets stuck at the feed inlet of the hopper 4 during the feeding process, and there is a lack of active unblocking structure, resulting in material accumulation and blockage even after long-term operation. This invention addresses this problem through the combination of the aforementioned components. Specifically, a pusher 11 located within the movable groove 10 on the surface of the metering cylinder 8 is linked to an eccentric disc 13. During the rotation of the metering cylinder 8, the pusher 11 is periodically pushed outward, forcibly breaking up the grain jam during feeding and eliminating the risk of blockage. The removable base plate 14 within the metering groove 9 is fixed with bolts, allowing for replacement of base plates of different thicknesses and flexible adjustment of the single-use metering volume. A spring 18 at the bottom of the pusher 11 provides a restoring force, ensuring that the pusher 11 retracts promptly after being pushed out by the eccentric disc 13. While the drive shaft 7 drives the metering cylinder 8 to rotate, it also drives the lever 19 to rotate through the synchronous wheel 22 and synchronous chain 21, causing the lever 20 to continuously agitate the grains in the hopper 4, preventing arching and bridging, thus achieving a dual protection of "rotational metering + active feeding". The above shows and describes the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and therefore all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
