[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0036] Please see Figure 1-4 As shown, this embodiment is a screening device for grain processing, comprising:

[0037] Main components: The main components include a processing frame 11, a screening frame 12, and a feeding hopper 13;

[0038] The screening frame 12 is installed inside the processing frame 11, and the feeding bin 13 is fixedly connected to the top of the screening frame 12;

[0039] The main components also include a collection box 14;

[0040] The collection box 14 is slidably connected to the bottom of the screening frame 12;

[0041] The collection box 14 is used to provide space for collecting the screened grain, and the feeding bin 13 is used to provide space for discharging the grain;

[0042] All of the above parts are existing technologies;

[0043] Screening assembly: The screening assembly includes a mounting groove 21, a guide groove 22, and a motor 23;

[0044] The mounting groove 21 is formed on the inner side wall of the processing frame 11, the guide groove 22 is formed on the rear part of the inner wall of the processing frame 11, and the motor 23 is fixedly connected to the inside of the mounting groove 21.

[0045] The output shaft of motor 23 is fixedly connected to turntable 24 via a coupling. Mounting groove 21 is used to provide mounting space for motor 23, and guide groove 22 is used to provide sliding space for slider 28.

[0046] With the auxiliary cooperation between motor 23 and turntable 24, the turntable 24 can be rotated by starting motor 23;

[0047] Working principle: When staff are sorting grains;

[0048] First, after the staff pours the grain into the screening frame 12 through the feeding bin 13, they start the motor 23 to work, which causes the connecting end of the motor 23 to drive the turntable 24 to rotate, which in turn causes the connecting block 26 installed at the top to rotate.

[0049] Next, the connecting block 26 can drive the connecting rod 25, which is sleeved at one end, to rotate. The connecting rod 25 can drive the sleeve block 27, which is rotatably connected at one end, to slide. This allows the screening frame 12, which is fixedly connected to the sleeve block 27, to slide. The slider 28 installed at the rear of the screening frame 12 slides repeatedly inside the guide groove 22.

[0050] This step allows for rapid screening of grains and impurities.

[0051] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, also includes:

[0052] The auxiliary components include a fixing frame 31, a mounting plate 32, a pull handle 33, and a locking strip 34;

[0053] The fixed frame 31 is fixedly connected to the front end of the screening frame 12, the mounting plate 32 is slidably connected to the inside of the screening frame 12, the pull handle 33 is fixedly connected to the outside of the mounting plate 32, and the locking strip 34 is rotatably connected to the inside of the fixed frame 31.

[0054] The auxiliary components also include three sets of sieve plates 35;

[0055] Three sets of sieve plates 35 are fixedly connected at equal distances to the rear end of the mounting plate 32. The sieve plates 35 have an increasing filtration mesh size and a decreasing filtration aperture from top to bottom.

[0056] The fixed frame 31 provides space for the card strip 34 to rotate, and the pull handle 33 provides space for the card strip 34 to engage;

[0057] With the auxiliary cooperation between the fixed frame 31 and the mounting plate 32, the locking strip 34 and the pull handle 33 can be engaged and connected by flipping the locking strip 34 outward.

[0058] Working principle: When the staff cleans the device;

[0059] First, by flipping the locking strip 34 inside the fixed frame 31 inward, the staff can retract the locking strip 34 into the fixed frame 31 and release the limit formed between the pull handle 33 and the locking strip 34.

[0060] Next, by pulling out the mounting plate 32, the three sets of screen plates 35 installed at the rear end can be slid out from the inside of the screening frame 12.

[0061] This step helps staff clean the impurities screened out on the three sets of sieve plates 35.
