DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] Example 1

[0024] In one embodiment, Figure 1-Figure 3 As shown, a soybean meal screening machine for preventing discharge blockage comprises a bottom plate 100, four universal wheels 101 are arranged at the bottom of the bottom plate 100 to facilitate the movement of a screening box 103, a push handle 102 is arranged on one side of the bottom plate 100, a supporting mechanism for supporting the screening box 103 is arranged on the bottom plate 100, the supporting mechanism has a vibration reduction function, a feeding hopper 104 is arranged on the top of the screening box 103 to facilitate the feeding of soybean meal, a screening mechanism for grading and screening the soybean meal is arranged in the screening box 103, and a cleaning mechanism for cleaning the screening mechanism is arranged on the screening mechanism.

[0025] like Figure 1 and Figure 2 As shown, the support mechanism includes two support legs 201, and the support leg 201 is fixedly connected to one end of a shock absorber 202, and the other end of the shock absorber 202 is fixedly connected to the screening box 103. The shock absorber 202 plays a vibration reduction role and prolongs the service life of the support leg 201.

[0026] like Figure 2 and Figure 3 As shown, the screening mechanism includes a vibration motor 401, and the vibration motor 401 is fixedly arranged at the bottom of the screening box 103. The first screen plate 402 and the second screen plate 403 are fixedly arranged in the screening box 103. The first screen plate 402 and the second screen plate 403 divide the internal space of the screening box 103 into a first screening chamber, a second screening chamber and a third screening chamber from top to bottom, and the screening box 103 is provided with a discharge port 404 at the corresponding position of the first screening chamber, the second screening chamber and the third screening chamber. After screening by the first screen plate 402 and the second screen plate 403, soybean meal of different particle sizes stays in the first screening chamber, the second screening chamber and the third screening chamber respectively, and then is discharged through the discharge port 404.

[0027] The three discharge ports 404 are respectively connected to different soybean meal collecting mechanisms, and soybean meals with different particle sizes can be obtained after multi-stage screening.

[0028] The push handle 102 is provided with a plurality of stripes to increase friction, making it easier to push the screening box 103 to a suitable position.

[0029] like Figure 3As shown, the first sieve plate 402 and the second sieve plate 403 are tilted, and the inner bottom wall of the screening box 103 is tilted. The soybean meal rolls along the tilt angle of the first sieve plate 402 and the second sieve plate 403 to be discharged from the discharge port 404.

[0030] The first sieve plate 402 is provided with a first sieve hole, and the second sieve plate 403 is provided with a second sieve hole. The diameter of the first sieve hole is larger than the diameter of the second sieve hole, so as to facilitate grading and screening of soybean meal particles.

[0031] Example 2

[0032] The difference from Example 1 is that Figure 1-Figure 3 As shown, the cleaning mechanism includes a mounting plate 301, the mounting plate 301 is fixedly arranged on the bottom plate 100, a motor 302 is fixedly arranged on the mounting plate 301, the output end of the motor 302 is softly connected to one end of a rotating shaft 303, the other end of the rotating shaft 303 sequentially passes through the screening box 103, the second sieve plate 403 and the first sieve plate 402, the rotating shaft 303 is rotatably connected to the screening box 103, the second sieve plate 403 and the first sieve plate 402 respectively, and the rotating shaft 303 is rotatably connected to the first sieve plate 402, the second sieve plate 403 and the first sieve plate 402. Cleaning plates 304 are fixedly provided at the corresponding positions of the two sieve plates 403. The two cleaning plates 304 are slidably connected to the first sieve plate 402 and the second sieve plate 403 respectively. Starting the motor 302 can drive the rotating shaft 303 to rotate, and then drive the cleaning plates 304 to rotate. The bottom of the cleaning plates 304 can scoop up the soybean meal particles stuck on the first sieve plate 402 and the second sieve plate 403, and the scooped soybean meal will pass through the through holes opened on the cleaning plates 304 and fall back to the first sieve plate 402 or the second sieve plate 403 to continue screening.

[0033] Working principle: When in use, start the vibration motor 401, add soybean meal from the feed hopper 104 into the screening box 103, and soybean meal with large particles is blocked by the first screen plate 402 and cannot fall, and soybean meal with smaller particles passes through the first screening hole on the first screen plate 402 and falls on the second screen plate 403, and soybean meal with even smaller particles continues to pass through the second screening hole on the second screen plate 403 and falls into the third screening cavity, and the screened soybean meal is discharged from the corresponding discharge port 404. During the screening process, start the motor 302 to drive the rotating shaft 303 to rotate, so that the cleaning plate 304 cleans the first screen plate 402 and the second screen plate 403 to prevent the soybean meal from being blocked at the first screening hole and the second screening hole, thereby ensuring the screening efficiency.

[0034] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
