Description

Technical Field

[0001] This utility model relates to the field of peanut processing technology, and in particular to an impurity removal device for peanut processing. Background Technology

[0002] Existing peanut processing methods rely heavily on manual screening or single screening equipment for impurity removal, which has significant limitations. Manual screening is inefficient, costly, and prone to causing impurities to remain due to fatigue. Traditional equipment, which only uses simple screening or wind power for impurity removal, is unable to separate light dust from small particles of sand and gravel, resulting in poor impurity removal. In addition, most of the equipment has a fixed structure, making filter cleaning inconvenient and prone to clogging, which affects continuous operation and brings certain adverse effects to users. In order to overcome the shortcomings of existing technologies, we propose an impurity removal device for peanut processing. Utility Model Content

[0003] The main objective of this invention is to provide an impurity removal device for peanut processing, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A peanut processing impurity removal device includes an impurity removal box and a feed hopper fixedly connected to the top of the impurity removal box. Multiple guide plates are fixedly connected inside the impurity removal box, and multiple fans are detachably embedded at the rear end of the impurity removal box. A fixed frame is fixedly connected to the rear end of the impurity removal box, and a first filter screen is detachably installed inside the fixed frame. A second filter screen is detachably embedded at the front end of the impurity removal box. A fixed box is also fixedly connected to the front end of the impurity removal box, and a filter element is inserted inside the fixed box. Discharge ports are fixedly connected to both sides of the impurity removal box, and a fixed plate is fixedly connected inside the impurity removal box. A servo motor is detachably connected to the front end of the impurity removal box. A rotating rod is detachably connected to the output shaft of the servo motor, and a cam is fixedly connected to the outer surface of the rotating rod. A rolling groove is opened on the outer peripheral surface of the cam, and a roller is rolled in the rolling groove. A mounting seat is provided above the roller, and a connecting shaft passes through the connection between the roller and the mounting seat. A fixing rod is fixedly connected to the upper end of the mounting seat, and a spring is sleeved on the outer surface of the fixing rod between the fixing plate and the mounting seat. A screening plate is fixedly connected to the upper end of the fixing rod.

[0005] Preferably, the plurality of guide plates are arranged alternately in an inclined manner, and the inclination directions of two adjacent guide plates are opposite.

[0006] Preferably, the mesh diameter of the second filter screen is smaller than the minimum diameter of the peanut particles, the second filter screen is connected to the internal space of the fixed box, and the filter element is tightly fitted to the inner wall of the fixed box.

[0007] Preferably, the surface of the screening plate is provided with multiple screening holes, and the diameter of the screening holes is smaller than the diameter of normal peanut particles. The two side edges of the screening plate correspond to the positions of the discharge port.

[0008] Preferably, the outer peripheral surface of the roller is in close contact with the inner wall of the rolling groove, the fixing rod passes through the fixing plate and is slidably connected to the fixing plate, and the two ends of the spring abut against the lower surface of the fixing plate and the upper surface of the mounting base, respectively.

[0009] Preferably, the servo motor is fixedly connected to the front end of the impurity removal box by bolts, and the end of the rotating rod away from the servo motor is rotatably connected to the rear side wall of the impurity removal box by a bearing. Multiple cams are evenly distributed along the length of the rotating rod.

[0010] Compared with the prior art, the present invention has the following beneficial effects: This peanut processing impurity removal device uses inclined, alternately distributed guide plates to guide peanuts in an S-shape, extending their contact time with the airflow. Combined with a fan, this creates a directional airflow that efficiently separates light impurities from the peanuts. The first filter screen filters out external impurities entering the fan, while the second filter screen works in conjunction with the filter element in the fixed box to prevent peanut particles from leaking out and to collect and filter light impurities, effectively improving impurity removal efficiency and reducing impurity residue. Furthermore, all filters and filter elements are removable for easy cleaning and maintenance.

[0011] This peanut processing impurity removal device uses a servo motor to drive a cam to rotate. Through the cooperation of the rolling groove and rollers, the screening plate vibrates at high frequency under the elastic action of the spring, which can quickly separate small particle impurities from peanuts. The diameter of the screening holes on the screening plate is smaller than that of normal peanut particles, ensuring that small impurities fall accurately. Qualified peanuts are discharged from the discharge port along the vibration direction, realizing graded screening. Attached Figure Description

Detailed Implementation

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] Example 1, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a peanut processing impurity removal device includes an impurity removal box 1, a feed hopper 2 welded and fixed to the top of the impurity removal box 1, multiple guide plates 3 arranged in an inclined alternating pattern with adjacent plates in opposite inclination directions, and welded and fixed to the inner wall of the impurity removal box 1, a blower 4 detachably embedded in a pre-set mounting hole at the rear end of the impurity removal box 1 by bolts, with the air outlet facing inward, a fixing frame 5 welded to the rear end of the impurity removal box 1 and located outside the blower 4, a first filter screen 6 detachably installed in the fixing frame 5 by bolts and covering the blower inlet, a second filter screen 7 detachably embedded in the corresponding opening at the front end of the impurity removal box 1 by bolts, with its edge tightly fitted to the inner wall of the box, its mesh diameter being smaller than the minimum diameter of peanut particles, and communicating with the internal space of the fixing box 8, the fixing box 8 welded to the front end of the impurity removal box 1, a filter element 9 inserted into the fixing box 8 and tightly fitted to the inner wall, a discharge port 10 welded and fixed to both sides of the impurity removal box 1, the position corresponding to the two sides of the screening plate 21, and the fixing plate 11 welded and fixed to the inner wall. The servo motor 12 is fixed inside the impurity removal box 1 and is detachably connected to the front end of the impurity removal box 1 by bolts. Its output shaft is detachably connected to the rotating rod 13. The end of the rotating rod 13 away from the servo motor 12 is rotatably connected to the rear side wall of the impurity removal box 1 by bearing. Multiple cams 14 are fixedly connected to the outer surface of the rotating rod 13 and are evenly distributed along its length. The outer circumferential surface of the cam 14 has a rolling groove 15. A roller 16 is rolled in the groove. A mounting seat 17 is provided above the roller 16. A connecting shaft 18 passes through the connection between the two. A fixing rod 19 is fixedly connected to the upper end of the mounting seat 17. The fixing rod 19 passes through the fixing plate 11 and is slidably connected to it. A spring 20 is sleeved on its outer surface between the fixing plate 11 and the mounting seat 17. The two ends of the spring 20 abut against the lower surface of the fixing plate 11 and the upper surface of the mounting seat 17, respectively. A screening plate 21 is fixedly connected to the upper end of the fixing rod 19. Multiple screening holes with a diameter smaller than normal peanut particles are opened on the surface of the screening plate 21.

[0016] It should be noted that this utility model is an impurity removal device for peanut processing. In use, peanuts are fed into the feed hopper 2. Under the action of the inclined, alternately distributed guide plates 3, the peanuts fall in an S-shape. Simultaneously, the blower 4 is activated. Light impurities are carried by the airflow through the second filter screen 7 into the fixed box 8 and filtered by the filter element 9. The first filter screen 6 prevents external impurities from entering. After the peanuts fall onto the screening plate 21, the servo motor 12 is activated. Its output shaft drives the rotating rod 13 and cam 14 to rotate. The rolling groove 15 of the cam 14 cooperates with the roller 16, causing the... The mounting base 17 drives the screening plate 21 to vibrate at high frequency under the action of the spring 20 through the fixing rod 19. Small particles of impurities fall through the screening holes of the screening plate 21, and qualified peanuts move to both sides under the action of vibration and are discharged from the discharge port 10, thus completing the impurity removal. For different peanut varieties, the corresponding specifications of the screening plate 21 and filter element 9 can be replaced. The vibration frequency of the screening plate 21 can be changed by adjusting the speed of the servo motor 12. When the first filter screen 6 and the second filter screen 7 are clogged, they can be directly disassembled for cleaning or replacement. Springs 20 with different elastic coefficients can also be selected according to the hardness of the peanuts.
