[0028] The destoner is an important processing equipment used in the grain processing and milling industry. Its function is to remove stones and other debris from rice. Generally, the rice is rolled over a sieve plate to screen out stones and other debris in the rice.

[0029] In the related art, the existing stone removal machine adds materials at the upper end of the screen plate when adding materials, but the added rice is generally in a pile shape, so it cannot be evenly distributed on the surface of the screen plate when sliding downward, resulting in low screening efficiency.

[0030] In order to solve the problems in the related art to a certain extent, an embodiment of the present application provides a rice stone removing machine, which makes the rice between the two partitions roll downward evenly from the lateral range of the filter screen plate.

[0031] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0032] Combination Figure 1-Figure 5The embodiment of the present application provides a rice stone removing machine, including a filtering screen plate 1, the bottom surface and the right end of the filtering screen plate 1 are fixedly connected with a collecting box 2, the left end of the filtering screen plate 1 is higher than the right end thereof, and the front sides of the two collecting boxes 2 are both open. After the rice is added from the top of the filtering screen plate 1, the rice can roll downward on the filtering screen plate 1, and the internal materials can be taken out from the opening structures of the two collecting boxes 2 respectively. The left end of the filtering screen plate 1 is fixedly connected with a vertical plate 3, and two transmission wheels 7 are arranged on the left side of the vertical plate 3. The two transmission wheels 7 are driven by a conveyor belt 6. The front end of the transmission wheel 7 located at the top is fixedly sleeved with a friction wheel 19, and a friction plate 21 is arranged below the friction wheel 19. The bottom surface of the friction plate 21 is fixedly connected with a pushing telescopic rod 20, and the lower end of the pushing telescopic rod 20 is fixedly connected to the front side of the vertical frame 15. The pushing telescopic rod 20 pushes the friction plate 21 to apply thrust to the friction wheel 19, thereby increasing the resistance encountered by the friction wheel 19 when rotating, thereby increasing the resistance encountered by the driving wheel 7 and the conveyor belt 6 when rotating.

[0033] In some embodiments, the front end of the vertical plate 3 is fixedly connected to the side plate 18, a lower hopper 4 is arranged in front of the side plate 18, a cylinder 5 is fixedly inserted on the back of the lower hopper 4, and the side plate 18 is fixedly sleeved on the rear end of the cylinder 5. A plurality of partitions 8 are fixedly installed on the outer ring surface of the conveyor belt 6. The partitions 8 are arranged vertically to the outer ring surface of the conveyor belt 6. A plurality of partitions 8 are equidistantly distributed on the outer surface of the conveyor belt 6. A movable plate 10 is arranged between every two adjacent partitions 8, and the movable plate 10 is slidably inserted into the inside of the adjacent partitions 8.

[0034] In some embodiments, a soft end plate 13 is fixedly sleeved on the outer surface of the vertical conveyor belt 6, and the soft end plate 13 is located behind a plurality of partitions 8. A push spring 12 is fixedly connected to the back of the movable plate 10, and the push spring 12 has a tendency to push the movable plate 10 to move forward. A round rod 11 is arranged on the inner side of the push spring 12, and the front end of the round rod 11 is fixedly connected to the back of the movable plate 10. A round hole 14 is provided on the front of the soft end plate 13 and behind each round rod 11. As the amount of rice charged in front of the movable plate 10 increases, the movable plate 10 gradually compresses the push spring 12, and gradually passes the round rod 11 from the round hole 14 to the back of the soft end plate 13.

[0035] In some embodiments, a sealing plate 22 is provided on the side of the movable plate 10 away from the conveyor belt 6, and the rear end of the sealing plate 22 is elastically rotatably connected to the soft end plate 13. The elastically connected sealing plate 22 has a tendency to move away from the conveyor belt 6. When the sealing plate 22 contacts the vertical plate 3, the sealing plate 22 can block the outer side between the two partitions 8 to prevent leakage of rice between them. After the sealing plate 22 is separated from the vertical plate 3, the sealing plate 22 elastically connected to the soft end plate 13 rotates away from the conveyor belt 6. When the partition 8 rotates to the right side of the conveyor belt 6, the left end of the partition 8 is higher than the right end, which facilitates the rice between the two partitions 8 to slide onto the top of the filter screen plate 1. The left side of the lower hopper 4 is fixedly connected to the vertical frame 15, and the two transmission wheels 7 are rotatably connected to the upper and lower ends of the vertical frame 15 respectively.

[0036] In some embodiments, a power structure 9 is fixedly connected to the back of the vertical frame 15, and the power structure 9 includes a reciprocating power telescopic rod 901, a horizontal plate 902 and a one-way plate 903. The left end of the one-way plate 903 is elastically rotatably connected to the right upper end of the horizontal plate 902, the lower end of the reciprocating power telescopic rod 901 is fixedly connected to the upper surface of the horizontal plate 902, and the upper end of the reciprocating power telescopic rod 901 is fixedly connected to the back of the vertical frame 15. The reciprocating power telescopic rod 901 drives the one-way plate 903 to move reciprocatingly up and down through the horizontal plate 902. The right end of the one-way plate 903 elastically connected to the horizontal plate 902 has a tendency to rotate downward. When the one-way plate 903 contacts the round rod 11 during downward movement, the one-way plate 903 is dislocated from the round rod 11 by rotating upward relative to the horizontal plate 902. When the one-way plate 903 moves upward and contacts the round rod 11, it can push the round rod 11 to move upward, drive the conveyor belt 6 to rotate, and make the two adjacent partitions 8 located below the cylinder 5 connected to the cylinder 5.

[0037] In some embodiments, a spiral feed plate 17 is rotatably inserted inside the cylinder 5, and the front end of the spiral feed plate 17 rotates and passes through the front inner wall of the lower hopper 4. The front of the lower hopper 4 is fixedly connected to the motor 16, and the front end of the spiral feed plate 17 is fixedly connected to the output end of the motor 16. The bottom surface of the vertical plate 3 is fixedly connected to the outer plate 23, and multiple partitions 8 are all located on the inner side of the outer plate 23. When the spiral feed plate 17 rotates, the rice in the lower hopper 4 can be pushed through the cylinder 5 into between the two corresponding partitions 8 behind the cylinder 5.

[0038] When in use, the rice to be screened is put into the lower hopper 4, the motor 16 drives the spiral feeding plate 17 to rotate, and the reciprocating power telescopic rod 901 drives the one-way plate 903 to move up and down reciprocatingly through the cross plate 902. When the spiral feeding plate 17 rotates, the rice in the lower hopper 4 is pushed into the space between the two corresponding partitions 8 behind the cylinder 5. As the amount of rice between the two partitions 8 increases, the movable plate 10 at the rear is gradually pushed to compress the push spring 12. When the round rod 11 extends from the round hole 14 to the rear of the soft end plate 13, the one-way plate 903 moves upward and When the round rod 11 contacts, it can push the round rod 11 to move upward for a certain distance, drive the conveyor belt 6 to rotate, and at the same time make the space between the two partitions 8 located below move to be connected with the cylinder 5, so that the rice can be filled in front of the new movable plate 10, ensuring that the conveyor belt 6 rotates again after the two partitions 8 are filled, and the partition 8 filled with rice moves to the top of the filter screen plate 1, so that the rice between the two partitions 8 rolls down evenly from the lateral range of the filter screen plate 1, and the filter screen plate 1 separates the stones and debris from the rice, and falls into the two collection boxes 2 respectively.

[0039] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application.

Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples described in this specification.

[0040] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
