Description

Technical Field

[0001] This utility model relates to the field of rice production technology, specifically a color sorter for rice production. Background Technology

[0002] Rice is a finished product made from paddy through processes such as cleaning, hulling, milling, and finishing. Rice color sorters are machines that automatically sort out discolored particles in rice based on the differences in the optical properties of rice using photoelectric technology, thereby improving rice quality and removing impurities. Under the action of a light source, the system generates an output signal based on the intensity and color change of the light, which drives the solenoid valve to blow out discolored particles into the waste chamber of the receiving hopper, thus performing color sorting and impurity removal on the rice.

[0003] According to Chinese Utility Model Application No. 202222464099.3, a color sorting and impurity removal device for processing high-quality rice is proposed. The utility model describes that "the device is equipped with a feeding mechanism, which drives the transmission rod and cam to rotate through the drive motor, and pushes the limit block to move up and down reciprocally to feed the material intermittently, so that the material is fed in batches to avoid the accumulation of material, and to evenly disperse the material, so as to accurately sort out the inferior rice in the material, thereby improving the sorting efficiency of the material."

[0004] In this color sorting and impurity removal equipment for high-quality rice processing, when the feeding troughs on both sides of the limiting block detach from the inner wall of the feeding box, the rice in the feeding box enters the feeding trough and falls onto the flat feeding plate for conveying. The flat feeding plate then conveys the material to the color sorter body for color sorting and impurity removal. However, the rice poured into the feeding box may accumulate, resulting in a situation where some areas are high and others are low, affecting the uniformity of rice feeding and reducing the sorting efficiency of the color sorter. Therefore, a color sorter for rice production is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a color sorter for rice production, which has advantages such as uniform feeding. It solves the problem that rice poured into the feeding box may accumulate, resulting in localized high-rice-periphery imbalances, affecting the uniformity of rice feeding and reducing the sorting efficiency of the color sorter.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a color sorter for rice production, comprising a color sorter body, a feeding bin on the color sorter body, a feeding hole on the side wall of the feeding bin, a blocking mechanism for blocking the feeding hole on the feeding bin, a driving mechanism on the feeding bin, and a leveling mechanism on the driving mechanism.

[0007] The driving mechanism includes a driving chamber, which is fixedly connected to the outer wall of the feeding chamber. A motor is fixedly installed on the outer wall of the driving chamber. The output end of the motor passes through the driving chamber and is fixedly installed with a first threaded rod. A first threaded sleeve is installed on the outer thread of the first threaded rod. A driving rod that passes through and extends into the feeding chamber is fixedly installed on the outer side of the first threaded sleeve. The flattening mechanism is disposed on the driving rod.

[0008] Furthermore, the shielding mechanism includes a first horizontal plate, which is fixedly connected to the outer wall of the feeding hopper. An electric push rod is fixedly installed on the top of the first horizontal plate. The output end of the electric push rod passes through the first horizontal plate and is fixedly installed with an L-shaped plate. A shielding plate is fixedly installed at the bottom of the L-shaped plate.

[0009] Furthermore, the leveling mechanism includes a second horizontal plate, which is fixedly connected to the outside of the drive rod. A second threaded sleeve is fixedly installed at the bottom of the second horizontal plate, and a second threaded rod is installed inside the threaded sleeve. The top of the second threaded rod passes through the second horizontal plate and is fixedly installed with a handwheel. A movable plate is rotatably installed at the bottom of the second threaded rod via a bearing, and a leveling plate is fixedly installed at the bottom of the movable plate.

[0010] Furthermore, a first slider extending into the interior of the feeding bin is fixedly installed on the outside of the L-shaped plate, and a first groove matching the first slider is opened inside the feeding bin.

[0011] Furthermore, the inside of the feeding bin is provided with a through hole, which is matched with the drive rod.

[0012] Furthermore, a second slider extending into the interior of the feeding bin is fixedly installed on the outside of the second horizontal plate, and a second groove matching the second slider is provided inside the feeding bin.

[0013] Furthermore, a limiting rod is fixedly installed on the top of the movable plate, extending through and above the second horizontal plate, and a limiting plate is fixedly installed on the top of the limiting rod.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] This color sorter for rice production consists of a color sorter body, a feeding hopper, a blocking mechanism, a drive mechanism, and a leveling mechanism. First, the blocking mechanism blocks the feeding hole of the feeding hopper. Then, rice is poured into the inside of the feeding hopper. Next, the drive mechanism drives the leveling mechanism to level the rice. Finally, the blocking mechanism removes the blockage from the feeding hole of the feeding hopper, allowing the rice to slide through the feeding hole into the inside of the color sorter body. Because the rice inside the feeding hopper is leveled, the occurrence of local highs and lows around the edges is reduced, improving the uniformity of rice feeding and increasing the sorting efficiency of the color sorter body.

[0024] Please see Figure 1-6 This embodiment of a color sorter for rice production includes a color sorter body 1, a feeding bin 2 on the color sorter body 1, the feeding bin 2 being fixedly connected to the top of the color sorter body 1 by four vertical rods, five feeding holes being opened on the side wall of the feeding bin 2, the five feeding holes being evenly and equidistantly distributed, the color sorter body 1 including five slides, the color sorter body 1 being prior art, the internal structure, connection method and working principle of the color sorter body 1 being disclosed, and therefore not described in detail, the five feeding holes being located directly above the five slides, the feeding bin 2 being provided with a blocking mechanism 3 for blocking the feeding holes, the feeding bin 2 also being provided with a driving mechanism 4, the driving mechanism 4 being provided with a leveling mechanism 5.

[0025] Specifically, the blocking mechanism 3 is first used to block the discharge hole of the discharge bin 2, then the rice is poured into the interior of the discharge bin 2, and then the driving mechanism 4 is used to drive the leveling mechanism 5 to level the rice. Finally, the blocking mechanism 3 is used to remove the blockage from the discharge hole of the discharge bin 2, and the rice slides through the discharge hole into the interior of the color sorter body 1. Because the rice inside the discharge bin 2 is leveled, the occurrence of local high and low areas is reduced, the uniformity of rice discharge is improved, and the sorting efficiency of the color sorter body 1 is improved.

[0026] In this embodiment, the shielding mechanism 3 includes a first horizontal plate 31, which is fixedly connected to the outer wall of the feeding bin 2. An electric push rod 32 is fixedly installed on the top of the first horizontal plate 31.

Five shielding plates 34 are fixedly installed on the bottom of the L-shaped plate 33. The five shielding plates 34 are respectively located directly above the five feeding holes.

[0027] Specifically, by activating the electric push rod 32, when the electric push rod 32 moves the L-shaped plate 33 and the five blocking plates 34 downward, the five blocking plates 34 block the five discharge holes respectively. When the electric push rod 32 moves the L-shaped plate 33 and the five blocking plates 34 upward, the five blocking plates 34 unblock the five discharge holes respectively.

[0028] In this embodiment, the drive mechanism 4 includes a drive chamber 41, which is fixedly connected to the outer wall of the feeding chamber 2. A motor 42 is fixedly installed on the outer wall of the drive chamber 41. The output end of the motor 42 passes through the drive chamber 41 and is fixedly installed with a first threaded rod 43. A first threaded sleeve 44 is installed on the external thread of the first threaded rod 43. A drive rod 45 that passes through and extends into the feeding chamber 2 is fixedly installed on the outside of the first threaded sleeve 44. A through hole is opened inside the feeding chamber 2, and the through hole matches the drive rod 45.

[0029] Specifically, by turning on the motor 42, the motor 42 drives the first threaded rod 43 to rotate, and the first threaded rod 43 drives the first threaded sleeve 44 and the drive rod 45 to move linearly.

[0030] In this embodiment, the leveling mechanism 5 includes a second horizontal plate 51, which is fixedly connected to the outside of the drive rod 45. A second slider extending into the material feeding hopper 2 is fixedly installed on the outside of the second horizontal plate 51. A second groove matching the second slider is opened inside the material feeding hopper 2. A second threaded sleeve 52 is fixedly installed at the bottom of the second horizontal plate 51. A second threaded rod 53 is threaded inside the second threaded sleeve 52. A handwheel 54 is fixedly installed at the top of the second threaded rod 53 through the second horizontal plate 51.

A limiting plate is fixedly installed at the top of the limiting rod. A leveling plate 56 is fixedly installed at the bottom of the movable plate 55. The bottom of the leveling plate 56 is arc-shaped.

[0031] Specifically, by turning the handwheel 54, the handwheel 54 drives the second threaded rod 53 to rotate, and the second threaded rod 53 drives the moving plate 55 and the spreading plate 56 to move up and down.

[0032] The working principle of the above embodiments is as follows:

[0033] First, the operator activates the electric push rod 32, which moves the L-shaped plate 33 and five baffle plates 34 downwards. The five baffle plates 34 then block the five feeding holes. Rice is then poured into the feeding hopper 2. Next, the operator turns the handwheel 54, which rotates the second threaded rod 53. The second threaded rod 53 moves the moving plate 55 and the spreading plate 56 downwards. The spreading plate 56 is moved to the appropriate position according to the amount of rice. Then, the operator starts the motor 42, which rotates the first threaded rod 43. 43 drives the first threaded sleeve 44, drive rod 45 and spreading plate 56 to move linearly. Spreading plate 56 spreads the rice. Finally, electric push rod 32 is activated. Electric push rod 32 drives L-shaped plate 33 and five baffle plates 34 to move upward. The five baffle plates 34 release the obstruction of the five feeding holes respectively. The rice slides through the feeding holes into the interior of the color sorter body 1. Because the rice inside the feeding bin 2 is spread out, the occurrence of local high and low around the perimeter is reduced, the uniformity of rice feeding is improved, and the sorting efficiency of color sorter body 1 is improved.
