One end of the hydraulic cylinder 10 is installed with a hydraulic oil main pipe 12, and the two ends of the inner front and rear surfaces of the peanut screening box 3 are installed with four The telescopic sleeve 13, the telescopic sleeve 13 and the hydraulic oil main pipe 12 are connected by a hydraulic branch pipe 14, a telescopic piston 15 is movably installed in the telescopic sleeve 13, a telescopic column 16 is installed on the telescopic piston 15, and the telescopic column 16 is connected with the telescopic sleeve The cylinder 13 is movably connected, and a filter sieve plate 17 is arranged between the corresponding two telescopic columns 16. The filter sieve plate 17 and the telescopic column 16 are connected by a bearing 18. The filter sieve plate 17 is in a downwardly inclined state. The size of 17 is more than half of the length of the peanut screening box 3. The filtering screen plates 17 are distributed in the peanut screening box 3 crosswise. The filtering screen plates 17 are distributed in the peanut screening box 3 in a stepped manner. The work of the rotating motor 7 drives the two telescopic The staggered expansion and contraction of the piston 15 causes the filter screen plate 17 to start reciprocating motion to screen peanuts, and the screening effect of peanuts is improved by designing multi-layer screening.

The invention of the present application lies in the structural design of the adjusting screen plate device. With reference to FIG. 1 , the adjusting screen plate device is provided with a fixed straight rod 20 through an electric telescopic rod 19 , and a plurality of horizontal rods 22 are installed on the fixed support rod 20 . A tension spring 23 is installed at the lower end of the 22, and the lower end of the tension spring 23 is fixedly connected with the filter screen plate 17. The height of the cross bar 22 is adjusted through the electric telescopic rod 19, and the angle of the filter screen plate 17 is adjusted, thereby adjusting the screening efficiency of peanuts. At the same time, through the design of the tension spring 23, when there are too many peanuts on the filter sieve plate 17, the expansion and contraction of the tension spring 23 can accelerate the sliding of the peanuts, thereby facilitating the screening of peanuts.

The invention of the present application lies in the structural design of the impurity recovery device. With reference to the accompanying drawings 1, 4 and 2, the impurity recovery device includes a number of impurity recovery ports 24 on both side surfaces of the peanut screening box 3. The impurity recovery ports 24 is located below the filter sieve plate 17, the impurity recovery port 24 and the filter sieve plate 17 are connected by a square telescopic hose 25, a recovery pipe 26 is installed under both sides of the peanut screening box 3, and a suction pipe 26 is provided under the outer surface of the recovery pipe 26.

The working principle of the device: when it is necessary to screen peanuts, the staff controls the electric telescopic rod 19 to move up and down, the electric telescopic rod 19 drives the fixed support rod 20 to start to move through the lift, and the fixed support rod 20 moves to drive the horizontal rod 22 to start to move. Moving, the cross bar 22 drives the filter screen plate 17 to start to adjust the angle through the tension spring 23, thereby adjusting the speed of peanut screening by adjusting the inclination angle of the filter screen plate 17;

After the adjustment of the filter screen plate 17 is completed, the rotary motor 7 is controlled to start to work at this time. The rotary motor 7 drives the flange rotating disk 8 to start to rotate through rotation, and the flange rotating disk 8 drives the adjustment connecting rod 9 to start to move through the flange. The rod 9 starts to drive the two moving pistons 11 to start to move in the hydraulic cylinder 10 through the action of the flange rotating disk 8. When one of the moving pistons 11 moves out, the other moving piston 11 moves inward, so as to perform alternating reciprocating operation. , and the movement of the moving piston 11 drives the hydraulic oil to move, and through the action of the hydraulic oil, the telescopic piston 15 in the telescopic sleeve 13 begins to reciprocate, and the telescopic piston 15 drives the telescopic column 16 to start reciprocating motion, thereby driving the telescopic column 16 to reciprocate. The filter sieve plate 17 performs reciprocating motion, and the filter sieve plate 17 performs the screening of peanuts through the reciprocating shaking;

At the same time, the air suction pump 29 is controlled to start working, the air suction pump 29 starts to inhale through the holes on the filter screen, and the dander, dust and shriveled peanuts generated during peanut screening enter the square telescopic hose 25 through the holes, and then enter the Accumulation is carried out in the recovery pipe 26, and the fine filter screen is used to prevent dander, dust and dried peanuts from entering the air extraction pipe 27. When the impurities in the recovery pipe 26 are accumulated to a certain extent, the sealing cover 30 is opened to remove the dust. impurities are discharged;

When the peanuts enter into the peanut screening box 3 through the square cone peanut inlet 4, they fall onto the filter screen 17 and pass through the reciprocating motion of the filter screen 17, so that the peanuts are screened, and the peanuts are filtered by their own gravity and The inclination of the screen 17 begins to slowly slide down to the next filter screen 17, so as to screen again. After several screenings, the peanuts are collected through the conical funnel 5, and then discharged through the peanut outlet pipe 6. outside world;

In this device, through the action of the tension spring 23, it can effectively ensure that the peanuts can slide smoothly, and prevent the peanuts from accumulating too much on the filter sieve plate 17, resulting in insufficient screening. After the peanuts are piled up too much, the inclination angle of the filter sieve plate 17 is increased by pulling the tension spring 23 away, so that the peanuts slide down quickly, so as to screen.

The above technical solutions only represent the preferred technical solutions of the technical solutions of the present invention, and some changes that those skilled in the art may make to some parts of them all reflect the principles of the present invention and fall within the protection scope of the present invention.
