Description

Technical Field

[0001] This utility model relates to the field of rice grading and screening technology, specifically to a rice grading and screening device. Background Technology

[0002] Rice, also known as paddy rice or rice paddy, is an edible grain, an annual herbaceous plant that thrives in warm and humid conditions. In southern China, it is commonly called "rice" or "grain." The hulled grain is rice. Cooked rice is called rice (in northern China) or white rice (in southern China). Rice is one of my country's main food crops, with a long history of cultivation and a large planting area. Besides being a staple food, rice can also be used as a raw material for brewing alcohol and making maltose. Half of the world's population consumes it.

[0003] The quality grade of rice is not very uniform. Some grains are plump and large, while others are relatively small. When packaging rice, it is necessary to grade and screen it. Existing screening devices use vibrating machines to assist in screening. However, during the process, it is easy for the feeding speed to exceed the screening speed, causing the rice to pile up on the screen surface. As a result, the screen surface cannot be fully utilized, thus reducing the screening efficiency. Utility Model Content

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0032] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0033] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a rice grading and screening device.

[0034] Example 1:

[0035] Combination Figure 1-8As shown, the present invention provides a rice grading and screening device, including a material holding mechanism 100, a primary screening mechanism 200 and a secondary screening mechanism 300. The material holding mechanism 100 includes a primary box 110 and a secondary box 120 sleeved on the bottom of the primary box 110.

[0036] The primary screening mechanism 200 includes a filter part 210 embedded at the top of the primary box 110, a sorting part 220 rotatably attached to the top of the filter part 210, a cross 230 installed inside the primary box 110, and a motor 240 connected between the sorting part 220 and the cross 230.

[0037] The secondary screening mechanism 300 includes a filter part 310 connected to the top of the primary box 110 and a guide sleeve 320 sleeved on the top of the primary box 110. Both ends of the sorting part 220 are in contact with the inner wall of the filter part 310.

[0038] Furthermore, the first-stage box 110 has a discharge port on the front side, and the bottom of the cross 230 is flush with the top of the discharge port, thus providing a discharge port for easy removal of small rice grains from the first-stage box 110.

[0039] Furthermore, the filter unit 210 is composed of a solid disc 211 and a filter screen disc 212. The solid disc 211 is sleeved on the outside of the filter screen disc 212. The output shaft of the motor 240 rotates through the center of the solid disc 211. The structural design of the filter unit 210 prevents small rice grains from falling onto the motor 240, thus reducing the failure rate of the motor 240.

[0040] Furthermore, the sorting section 220 consists of a material distribution channel 221 and two filter screen base plates 222. The two filter screen base plates 222 are respectively close to both ends of the material distribution channel 221. The filter screen base plates 222 are embedded in the bottom of the material distribution channel 221. The mesh diameter of the filter screen base plate 222 is equal to the mesh diameter of the filter screen disk 212. The structural design of the sorting section 220 ensures that rice can only pass through the screen downwards at the position of the filter screen disk 212, effectively preventing the rice from contacting the motor 240 and further reducing the failure rate of the motor 240.

[0041] Furthermore, the second filtration section 310 is composed of a filter screen arc plate 311 and a solid arc plate 312. The solid arc plate 312 is integrally formed on the front side of the filter screen arc plate 311. The filter screen arc plate 311 is located on the top of the guide sleeve 320, and the solid arc plate 312 is located on the top of the discharge port. The structural design of the second filtration section 310 can prevent rice from falling out of the secondary box 120.

[0042] Example 2:

[0043] Combination Figure 1, 2 and Figure 7 As shown, based on Embodiment 1, the sorting section 220 is provided with a baffle assembly 400. The baffle assembly 400 includes two arc plates 410 connected to the outer wall of the sorting section 220 and a pressure cover 420 detachably connected between the two arc plates 410. The bottom of the pressure cover 420 fits against the top of the sorting section 220. The baffle assembly 400 can limit the rice in the distributing channel 221 so that the rice will not spill out from the top of the distributing channel 221 when it rotates with the distributing channel 221.

[0044] Example 3:

[0045] Combination Figure 1-2 As shown in the above embodiment, the top of the filter section 310 is provided with a feeding assembly 500. The feeding assembly 500 includes a horizontal plate 510 that rotatably passes through the top of the pressure cap 420 and a feeding pipe 520 that connects the filter section 310 and the horizontal plate 510. The arrangement of the horizontal plate 510 and the feeding pipe 520 allows rice to be stably injected into the feeding channel 221.

[0046] The working principle and usage process of this utility model are as follows: After rice is injected into the distribution channel 221 through the conveying pipe 520, the output shaft of the control motor 240 is rotated clockwise and counterclockwise. Under the action of centrifugal force, small rice grains in the distribution channel 221 pass through the filter screen bottom plate 222 and the filter screen disc 212, and are then collected by the primary box 110; while large rice grains pass through the filter screen arc plate 311 and fall into the secondary box 120 under the guidance of the guide sleeve 320, realizing the grading and classification collection of grains.

[0047] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
