Detailed Implementation

[0030] 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.

[0031] Reference Figure 2 - Figure 4 This utility model provides an embodiment of a high-efficiency screening device for a peanut shelling machine, comprising a frame 1, a sheller 2 fixedly installed on the inner wall of the frame 1, and a vibrating screen 3 provided on the inner wall of the frame 1. Both the sheller 2 and the vibrating screen 3 are existing technologies and will not be described in detail here. A material leveling mechanism 4 is provided at the bottom of the sheller 2, and a quantitative mechanism 5 is provided on the material leveling mechanism 4. The material leveling mechanism 4 includes an inclined plate 41, which is fixedly installed at the bottom end of the sheller 2. The inclined plate 41 is located at the discharge port of the sheller 2. When the sheller 2 discharges the shelled peanuts, the peanut shells and kernels adhere to the surface of the inclined plate 41 and slide into the vibrating screen 3. A rotating shaft 42 is rotatably connected through the inner wall of the inclined plate 41. A hollow rod 43 is fixedly installed at one end of the rotating shaft 42, and a guide plate 44 is fixedly installed at the other end of the rotating shaft 42. A sliding rod 45 is slidably connected to the inner wall of the inclined plate 41. A positioning shaft 46 is fixedly installed at the bottom of the sliding rod 45. The reciprocating sliding of the sliding rod 45, in conjunction with the positioning shaft 46 and the hollow rod 43, can drive the rotating shaft 42 to reciprocate on the inner wall of the inclined plate 41. A slide rail 47 is fixedly installed on the right side of the sliding rod 45. A motor 48 is fixedly installed at the bottom of the shell-opening machine 2. A rotating rod 49 is fixedly installed at the output end of the motor 48. An L-rod 410 is fixedly installed on the outer wall of the rotating rod 49. When the motor 48 is started, the rotating rod 49 is driven to rotate. When the rotating rod 49 rotates, it will drive the L-rod 410 to make a circular motion around the rotating rod 49.

[0032] Reference Figure 2 - Figure 4 The outer wall of the positioning shaft 46 is attached to the inner wall of the first hollow rod 43. When the slide rod 45 slides back and forth, it will drive the positioning shaft 46 to move back and forth against the inner wall of the first hollow rod 43. The outer wall of the L rod 410 is attached to the inner wall of the slide rail 47. When the rotating rod 49 rotates, it will drive the L rod 410 to move up and down against the inner wall of the slide rail 47. The guide plate 44 is located at the top of the inclined plate 41. When the rotating shaft 42 rotates back and forth, it will drive the guide plate 44 to swing back and forth at the top of the inclined plate 41. The bottom of the guide plate 44 is attached to the upper surface of the inclined plate 41. The first hollow rod 43 is located at the bottom of the inclined plate 41. The first hollow rod 43 can drive the rotating shaft 42 to rotate back and forth against the inner wall of the inclined plate 41.

[0033] Reference Figure 2 - Figure 4 The quantitative mechanism 5 includes a bucket 51, which is hinged to the outer wall of the inclined plate 41. The bucket 51 is located on the side of the inclined plate 41 furthest from the sheller 2. When the sheller 2 discharges peanut shells, the peanut shells slide down the inclined plate 41 into the inside of the bucket 51. A second hollow rod 52 is fixedly installed on the top right side of the bucket 51. The second hollow rod 52 drives the bucket 51 to swing up and down, which can quantitatively discharge the peanut shells onto the vibrating screen 3 for screening, avoiding excessive discharge of peanut shells and resulting accumulation. The right side of the inclined plate 41... A slider 53 is slidably connected to the inner side wall. A bent rod 54 is fixedly installed on the top of the slider 53. The outer wall of the bent rod 54 is attached to the inner wall of the second hollow rod 52. The reciprocating sliding of the slider 53, in conjunction with the bent rod 54 and the second hollow rod 52, can drive the bucket 51 to reciprocate up and down on the outer wall of the inclined plate 41. A connecting rod 55 is hinged to the outer wall of the slider 53. The end of the connecting rod 55 away from the slider 53 is hinged to the outer wall of the sliding rod 45. The reciprocating sliding of the sliding rod 45, in conjunction with the connecting rod 55, can drive the slider 53 to reciprocate on the side wall of the inclined plate 41.

[0034] Working principle: During use, after the sheller 2 finishes shelling the peanuts, it discharges the peanut shells and kernels downwards. At the same time, the motor 48 is started, driving the rotating rod 49 to rotate. As the rotating rod 49 rotates, it causes the L-rod 410 to move up and down against the inner wall of the slide rail 47. Simultaneously, the L-rod 410 pushes and pulls the slide rail 47 back and forth, causing the slide rail 47 to drive the slide rod 45 to slide back and forth against the inner wall of the inclined plate 41. As the slide rod 45 slides back and forth, it causes the positioning shaft 46 to move back and forth against the inner wall of the first hollow rod 43. At the same time, the positioning shaft 46 will push and pull the first hollow rod 43 back and forth. At this time, the first hollow rod 43 will drive the rotating shaft 42 to rotate back and forth on the inner wall of the inclined plate 41. While the rotating shaft 42 rotates back and forth, it will drive the guide plate 44 to swing back and forth on the top of the inclined plate 41. During the back and forth swinging process, the guide plate 44 can guide the peanut kernels and peanut shells discharged from the sheller 2, so that the peanut shells can be evenly spread on the vibrating screen 3, thereby enabling the vibrating screen 3 to fully exert its screening performance and improve the screening efficiency of peanut shells.

[0035] As the sliding rod 45 slides back and forth on the inner wall of the inclined plate 41, it pushes and pulls the connecting rod 55 back and forth, causing the connecting rod 55 to push and pull the slider 53 back and forth. At this time, the slider 53 slides back and forth on the side wall of the inclined plate 41. While the slider 53 is sliding back and forth, it will drive the bent rod 54 to move back and forth against the inner wall of the second hollow rod 52. At the same time, the bent rod 54 will push and pull the second hollow rod 52 back and forth, causing the second hollow rod 52 to drive the bucket 51 to rotate up and down on the outer wall of the inclined plate 41. When the bucket 51 rotates upward, it can push the inclined plate 41 back and forth. The shovel 51 catches the falling peanut shells, preventing them from falling onto the vibrating screen 3. When the shovel 51 rotates downward to an inclined state, the peanut shells inside the shovel 51 will fall onto the vibrating screen 3 for screening. Therefore, the up-and-down reciprocating rotation of the shovel 51 can quantitatively discharge peanut shells onto the vibrating screen 3 for screening, allowing the vibrating screen 3 to screen the peanut shells evenly and thoroughly, avoiding excessive discharge of peanut shells and resulting in accumulation, thereby improving the screening effect of peanut shells.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
