The driving assembly 2 includes a horizontal plate 201 fixedly installed at the center position of the outer bottom surface on both sides of the screen 104. The ends of the two horizontal plates 201 are fixedly connected to the outer top surface of the screen 2 105. A U-shaped frame 202 is provided on the right outer wall of the screening box 101. The two ends of the U-shaped frame 202 extend to the interior of the screening box 101 and are fixedly connected to the two horizontal plates 201. The U-shaped frame 202 is away from An ear plate 203 is fixedly installed at the center position of the outer wall of one side of the screening box 101, and a connecting plate 204 is rotatably installed on the inner side of the ear plate 203. A driving motor 205 is fixedly installed on the right outer wall of the screening box 101. The output end of the driving motor 205 is fixedly connected to a rotating shaft 206. An eccentric wheel 207 is fixedly installed on the outer peripheral surface of the rotating shaft 206. The outer wall of the eccentric wheel 207 is rotatably connected to the connecting plate 204 through a connecting rod. The left and right outer walls of the screening box 101 correspond to the screen mesh respectively. A through-type horizontal opening 106 and a horizontal opening 2 107 are provided at screen 104 and screen 2 105. Screen 104 and screen 2 105 are arranged in an inclined manner, and the inclined ends of screen 104 and screen 2 105 extend to the inner sides of horizontal opening 106 and horizontal opening 2 107 respectively. At the same time, the inclined top ends of screen 104 and screen 2 105 extend to the left and right outer walls of the screening box 101 respectively. The diameter of the sieve holes on screen 104 is larger than the diameter of the sieve holes on screen 2 105. The driving motor 205 is started to drive the rotating shaft 206 to rotate, thereby driving the eccentric wheel 207 to drive the U-shaped frame 202 to slide back and forth on the screening box 101 under the action of the connecting rod and the connecting plate 204, and then the cross plate 201 drives the screen 104 and the screen 2 105 to move back and forth synchronously, and then the pepper to be screened is transported to the inside of the screening box 101 along the feed cover 102 and falls on the outer surface of the screen 104, and then moves between the screen 104 and the screen 2. Under the reciprocating vibration of the screen 105, impurities such as leaves and pepper stems are filtered and discharged along the horizontal opening 106. The smaller-sized peppercorns will pass through the screen 104 and fall onto the outer surface of the screen 105 to be screened again. The peppercorns of different sizes after screening are then discharged along the horizontal opening 107 and the discharge cover 103 respectively, thereby realizing the dual screening process of impurities and peppercorns of different sizes, which is conducive to the subsequent classification and collection of peppercorns by size.

[0025] A transverse groove 3 is formed at the center of the inner walls on both sides of the screening box 101. Slide rods 301 are mounted on both inner sidewalls of the two transverse grooves 3. Slide blocks 302 are slidably sleeved on the outer circumferential surfaces of the two slide bars 301. Opposite sides of the two slide blocks 302 extend outside the transverse groove 3 and are fixedly connected to the two transverse plates 201. Return springs 303 are fixedly connected to the outer sidewalls of the two slide blocks 302 and located outside the slide rods 301. When screen 104 and screen 2 105 move back and forth, the slide blocks 302 are driven by the transverse plates 201 to slide on the slide rods 301 inside the transverse groove 3. The return springs 303 allow screen 104 and screen 2 105 to move back and forth stably inside the screening box 101, thereby ensuring the stability of the pepper screening process.

[0026] The working principle of the present invention is as follows: when in use, the drive motor 205 is first started to drive the rotating shaft 206 to rotate, thereby driving the eccentric wheel 207 to drive the U-shaped frame 202 to slide on the screening box 101 under the action of the connecting rod and the connecting plate 204, and then the cross plate 201 drives the screen 104 and the screen 2 105 to move back and forth synchronously.

[0027] At the same time, when screen 104 and screen 2 105 move back and forth, the horizontal plate 201 drives the slider 302 to slide on the slide rod 301 inside the horizontal groove 3, and with the assistance of the return spring 303, it is ensured that screen 104 and screen 2 105 move back and forth stably inside the screening box 101.

[0028] At the same time, the Sichuan peppercorns to be screened are transported along the feed cover 102 to the interior of the screening box 101 and fall onto the outer surface of screen 104. Then, under the reciprocating vibration of screen 104 and screen 2 105, impurities such as leaves and Sichuan peppercorns are intercepted and filtered and discharged along the horizontal opening 106. The smaller Sichuan peppercorns will pass through screen 104 and fall onto the outer surface of screen 2 105. Since the filter hole diameters of screen 104 and screen 2 105 are different, the Sichuan peppercorns can be screened again.

[0029] Finally, the different-sized peppercorns that have been screened are discharged along the second horizontal opening 107 and the discharge cover 103, thereby achieving a double screening process of impurities and peppercorns of different sizes, which is conducive to the subsequent classification and collection of peppercorns by size.

[0030] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention.
