Abstract

The present invention discloses a color-sorting combined rice milling machine, comprising a housing and a base fixedly connected to the housing. A feed hopper for feeding is integrally formed on the housing. A rice milling chamber is provided within the housing, through which brown rice can enter the rice milling chamber. The housing is rotatably connected to a rice roller shaft, and a rotating motor is mounted on the exterior of the housing. One end of the rice roller shaft is fixedly connected to the output end of the rotating motor. The rice roller shaft has a spiral portion that, when rotated, can propel the brown rice in the rice milling chamber forward. Two rice cutters are fixedly connected to the outer wall of the rice roller shaft. In the present invention, when the rice cutter rotates, the slide first contacts the arc surface of the arc block, gradually moving away from the fixed shaft. Then, at the moment of separation from the arc surface, it rapidly impacts and strikes the fixed shaft under the action of elastic force. Simultaneously, the second plate body also strikes the first plate body, generating vibrations that are transmitted to the rice cutter, which shakes off debris attached to the rice cutter through the vibration.

Description

Technical Field

[0001] The present invention relates to the technical field of rice processing equipment, in particular to a color sorting combined rice milling machine. Background Art

[0002] The rice mill is a key equipment in the field of rice processing. In the rice milling equipment, brown rice is milled into white rice. The brown rice enters the rice mill from the feed inlet and enters the rice milling chamber composed of rice milling rollers and sieve plates along the axial direction under the action of the spiral propeller. The brown rice grains are milled and peeled by the rice milling roller ribs and sieve plates. The milled rice grains flow out from the discharge bearing seat, thus completing the rice milling process.

[0003] The publication number is CN210022236U, and the name is "A rice roller for a rice mill and a rice milling machine". The invention discloses a rice roller shaft and a rice milling end. The rice roller shaft is provided with a rice milling end on the right side of the rice roller shaft, and a rice milling assembly is provided on the rice milling end. The rice milling assembly includes a rice knife mounting groove and a rice knife. The rice knife mounting groove is provided on the rice milling end, and a rice knife is installed on the rice knife mounting groove. However, the inventor found that during use, the brown rice is fully ground and scraped between the rice roller shafts to remove the surface and form fine powdery debris. The rice knife rotates with the rice roller shaft and contacts the inner wall of the rice milling chamber. After a long period of scraping, a large amount of debris will adhere to the contact part of the rice knife and the rice milling chamber. At the same time, the brown rice will also contain some moisture. The moisture combines with the attached debris to form a sticky substance and firmly accumulates at the contact part of the rice knife and the rice milling chamber. The formation of the sticky substance on the rice knife hinders the subsequent continuous advancement of the brown rice. Summary of the Invention

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] Reference Attachment Figure 1 -Attached Figure 7 A color sorting combined rice milling machine includes a casing 1 and a base 2 fixedly connected to the casing 1. A feed hopper 3 for feeding is integrally formed on the casing 1. A rice milling chamber 4 is provided in the casing 1. Brown rice can enter the rice milling chamber 4 through the feed hopper 3. The casing 1 is rotatably connected to a rice roller 5. A rotating motor 6 is installed outside the casing 1. One end of the rice roller 5 is fixedly connected to the output end of the rotating motor 6. The rice roller 5 has a spiral portion 38, which can push the brown rice entering the rice milling chamber 4 forward when rotating. Two rice knives 7 are fixedly connected to the outer wall of the rice roller 5. The rice knives 7 are in contact with the inner wall of the rice milling chamber 4.

[0035] The rice roller 5 has a rice milling part 8, which has a circular groove 9. The rice knife 7 is fixedly connected to the rice milling part 8 of the rice roller 5. The rice knife 7 passes through the rice roller 5 and extends into the circular groove 9. A striking component is provided in the rice knife 7. As the rice roller 5 rotates, the rice knife 7 is periodically struck to vibrate, thereby shaking off the debris attached to the rice knife 7 through the vibration.

[0036] A relatively fixed fixed shaft 10 is coaxially arranged in the circular groove 9. One side of the rice cutter 7 extending into the circular groove 9 extends to the outer wall of the fixed shaft 10 and contacts therewith. The outer wall of the fixed shaft 10 is fixedly connected with two symmetrically arranged arc blocks 11. The arc blocks 11 have a curved arc surface and a vertical straight surface. An elastic force is applied to the striking component to make it close to the outer wall of the fixed shaft 10. The rice cutter 7 also provides a through groove 14 for allowing the arc blocks 11 to pass through. When the rice cutter 7 rotates, the striking component first contacts the arc surface of the arc block 11 and gradually moves away from the fixed shaft 10. Later, at the moment of leaving the arc surface, it quickly impacts and hits the fixed shaft 10 under the action of the elastic force. The generated vibration is transmitted to the rice cutter 7, and the debris attached to the rice cutter 7 is shaken off by the vibration.

[0037] The striking component includes a chute 12 provided in the rice cutter 7, one end of the chute 12 corresponds to the outer wall of the fixed shaft 10, and two symmetrically arranged first plates 13 are fixedly connected in the chute 12. A slide plate 15 is also slidably connected in the chute 12, and the two sides of the slide plate 15 are fixedly connected to the second plate 16.

At the same time, the second plate 16 also hits the first plate 13, and the generated vibration is transmitted to the rice cutter 7, and the debris attached to the rice cutter 7 is shaken off by the vibration;

[0038] The elastic component includes a hollow airbag 18 made of rubber material. A first return spring 19 is provided in the airbag 18 so that the airbag 18 can recover its shape after being compressed.

The first disc 21 is fixedly connected to one end of the fixed shaft 10 coaxially. A sealing ring 23 is fixedly connected coaxially on the side of the first disc 21 facing the fixed shaft 10. The sealing ring 23 is made of rubber and is engaged between the rice roller shaft 5 and the casing 1 to prevent the brown rice in the rice milling chamber 4 from moving forward.

[0040] A hollow cylinder 24 is disposed between the first disc 21 and the second disc 22. A round rod 25 is slidably connected to the cylinder 24. A second return spring 26 is disposed within the cylinder 24. The ends of the second return spring 26 are connected to the inner wall of the cylinder 24 and the round rod 25, respectively. A discharge port 39 is defined in the housing 1. The discharge port 39 is disposed corresponding to the outer edge of the first disc 21. When the first disc 21 is moved by the forward movement of the brown rice, the ground and polished rice is discharged from the discharge port 39.

[0041] A plurality of air holes 27 are provided on the rice roller shaft 5. When the air bag 18 is compressed, the gas in the air bag 18 is discharged from the air hole 20 and then discharged from the air hole 27, thereby blowing the gas toward the direction where the rice cutter 7 is likely to adhere to debris. The wind force is used to blow away the debris and prevent the debris from adhering to the rice cutter 7.

[0042] A through opening 28 is provided on the casing 1, and the through opening 28 corresponds to the area between the first disc 21 and the second disc 22. A first circular hole 29 is provided in the center of the first disc 21, and the first circular hole 29 passes through the first disc 21. A second circular hole 30 is also provided in the center of the first disc 21, and the second circular hole 30 is connected to the first circular hole 29.

Under the elastic action of the second compression spring 34, the blocking block 33 blocks one end of the second circular hole 30. The fixed shaft 10 is a hollow structure and is provided with a plurality of small holes 35;

[0043] A collecting pool 36 is fixedly connected to the bottom of the casing 1 , and the opening of the collecting pool 36 corresponds to the discharge port 39 , so that the milled rice grains are collected in the collecting pool 36 , and the collecting pool 36 is provided with a door 37 that can be opened and closed.

[0044] Working principle:

[0045] Start the rotating motor 6, and the rice roller shaft 5 and the rice cutter 7 rotate synchronously;

[0046] The brown rice enters from the feed hopper 3 and is pushed forward by the spiral part of the rice roller 5, so that the brown rice continues to move forward in the rice milling chamber 4;

[0047] The brown rice is milled and peeled by the rice milling rollers, and the milled rice grains are pushed by the first disc 21 to open the discharge port 39 and are discharged;

[0048] The rice roller 5 and the rice cutter 7 rotate synchronously. The slide plate 15 first contacts the arc surface of the arc block 11 and gradually moves away from the fixed shaft 10. Then, at the moment of leaving the arc surface, it quickly impacts the fixed shaft 10 under the action of elastic force and hits the fixed shaft 10. At the same time, the second plate 16 also hits the first plate 13, and the generated vibration is transmitted to the rice cutter 7, which shakes off the debris attached to the rice cutter 7 through vibration.

[0049] When the slide plate 15 moves in the slide groove 12, the air bag 18 can be squeezed and deformed and then restored under the action of the first return spring 19 therein. When the air bag 18 is squeezed, the gas in the air bag 18 is discharged from the air hole 20 and can be discharged from the air hole 27 to blow away the debris through the action of wind.

[0050] The squeezed airbag 18 recovers under the elastic action of the first return spring 19. The airbag 18 absorbs gas to generate negative pressure, and the blocking block 33 squeezes the second return spring 26, allowing external gas to enter from the through port 28 and the first circular hole 29 and fill the gas originally lost by the airbag 18.

[0051] It should be noted that the white rice in the collection pool 36 enters the color sorting process. Through the vibration of the vibrator device, the selected material slides down the channel, accelerates to fall into the observation area in the sorting chamber, and passes through the sensor and the background plate. Under the action of the light source, according to the intensity and color change of the light, the system generates an output signal to drive the solenoid valve to blow out the different-colored particles into the waste material chamber of the receiving hopper, while the good selected materials continue to fall into the finished product chamber of the receiving hopper, thereby achieving the purpose of screening. This is the existing technology.

[0052] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
