[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model discloses a peanut processing screening machine, including a base 1, with a screening plate 2 at the upper end of the base 1. The screening plate 2 includes a rectangular frame 3 horizontally slidably disposed at the upper end of the base 1 and a mesh screen plate 4 disposed at the bottom of the rectangular frame 3. The base 1 is provided with a driving mechanism 5 for driving the rectangular frame 3 to reciprocate in the horizontal direction. In use, peanuts are poured into the screening plate 2, and the driving mechanism 5 drives the screening plate 2 to reciprocate at the upper end of the base 1, thus screening out the peanut kernels. The above is the prior art. The principle can be referred to the Chinese utility model patent for a peanut screening machine with authorization announcement number CN 220406292 U, which will not be elaborated here.

[0022] In view of the above-mentioned technology, after each screening, the peanuts on the surface of the screening plate 2 are not easy to remove. Therefore, the main innovation of this utility model is as follows, based on the existing technology:

[0023] A discharge port 6 for discharging whole peanuts is provided through the bottom of the rectangular frame 3 at the end away from the drive mechanism 5. A discharge baffle 7 is vertically and movably installed at the discharge port 6. The rectangular frame 3 is provided with a first drive mechanism 8 for driving the discharge baffle 7 to move downward and open the discharge port 6. A mesh screen plate 4 is movably disposed at the bottom of the rectangular frame 3, and the end of the mesh screen plate 4 near the discharge port 6 is rotatably connected to the bottom of the rectangular frame 3. The rectangular frame 3 is provided with a second drive mechanism 9 for driving the mesh screen plate 4 to rotate.

[0024] With the above structure, when the peanut screening is completed, the discharge baffle 7 can be driven to move upward by the first drive mechanism 8, so that the discharge port 6 at one end of the screening plate 2 can be opened. Then, the mesh screen plate 4 can be driven to rotate by the second drive mechanism 9, so that the peanuts in the screening plate 2 can be poured out from the discharge port 6.

[0025] In one embodiment of this application, the first drive mechanism 8 includes a telescopic cylinder fixed between the rectangular frame 3 and the discharge baffle 7.

[0026] In one embodiment of this application, the second drive mechanism 9 includes a motor fixed on the rectangular frame 3, and the output shaft of the motor is connected to the rotating shaft of the mesh screen plate 4.

[0027] In order to guide the movement of the screening plate 2, guide grooves 10 are provided on both sides of the upper end of the base 1, and guide wheels 11 are installed on both sides of the lower end of the rectangular frame 3. The guide wheels 11 are rolled in the guide grooves 10.

[0028] To facilitate the collection of the screened peanut kernels, the upper end of the base 1 is provided with an inclined discharge chute 15 at the bottom of the screening plate 2. A receiving box 12 for receiving peanut kernels is placed on the surface of the base 1. When the screening plate 2 moves back and forth, it drives the peanuts to move on the surface of the screening plate 2. During the movement of the screening plate 2, the peanut kernels fall into the inclined discharge chute 15 through the mesh of the mesh screen plate 4, and then roll down through the inclined discharge chute 15 and enter the receiving box 12.

[0029] To facilitate the collection of peanuts remaining on the surface of the screening plate 2 after screening, a feeding chute 13 is fixed at the bottom of the discharge port 6 on the rectangular frame 3. The discharge port of the feeding chute 13 is located on one side of the rectangular frame 3. After opening the discharge baffle 7, the peanuts on the surface are poured out through the discharge port 6 by rotating the mesh screen plate 4. The peanuts poured out through the discharge port 6 fall into the feeding chute 13. The user can collect the peanuts discharged from the feeding chute 13 from one side of the base 1.

[0030] Understandably, during use, the peanuts to be screened can be poured onto the surface of the screening plate 2 for screening. During the screening process, the peanut kernels fall through the mesh screen plate 4 at the bottom of the screening plate 2 onto the surface of the inclined discharge chute 15, and then are discharged into the receiving box 12 through the inclined discharge chute 15. After screening for a period of time, qualified peanuts remain on the surface of the screening plate 2. The discharge baffle 7 is opened and the mesh screen plate 4 is rotated to pour out the peanuts. After pouring out the peanuts, the positions of the discharge baffle 7 and the mesh screen plate 4 are restored, and peanuts to be screened can be added to the surface of the screening plate 2 again. The whole process does not require stopping the machine, thus improving the screening efficiency.

[0031] The bottom of the base 1 is equipped with casters 14 to facilitate the movement of the screening machine.

[0032] In summary, this utility model proposes a screening machine for peanut processing. It provides an openable and closable discharge port 6 and a first drive mechanism 8 for driving the opening and closing of the screening plate 2 at one end of the existing screening machine. At the same time, it provides a rotatable mesh screen plate 4 and a second drive mechanism 9 for driving the rotation of the screen plate 2 at the bottom. This enables the rapid discharge of peanuts after screening without the need for frequent machine stops and manual operation, and significantly improves the screening efficiency.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art 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 appended claims and their equivalents.
