Description

Technical Field

[0001] This utility model relates to the field of peanut screening machine technology, and in particular to peanut screening machine. Background Technology

[0002] A peanut screening machine is a mechanical device used in peanut processing to screen, clean, and sort peanuts. It can effectively screen out impurities, damaged particles, and non-standard peanuts, and separate peanuts of different specifications and qualities to ensure the quality and appearance of the final product.

[0003] Existing technologies, such as the utility model patent with publication number CN220406292U, disclose a peanut screening machine. This patent includes a frame; rollers mounted on both sides of the top of the frame; a screening plate rolling on the rollers; and a drive mechanism for driving the screening plate in reciprocating motion. The drive mechanism includes a first motor, a belt, a pulley, a crank, a connecting rod, and a shaft seat. The first motor is fixed to the frame, and a drive wheel is fixed to its main shaft. A rotating shaft is fixed through the center of the pulley and rotatably connected to the frame via the shaft seat. This utility model, by using a linkage mechanism in conjunction with a motor as the driving force for the screening plate, has a relatively simple equipment structure and good applicability. Furthermore, by using a reciprocating motion of the screening plate, the peanuts are less likely to be crushed, reducing the defective peanut rate.

[0004] In daily use, peanut sorting machines are mechanical devices used in peanut processing to screen, clean, and sort peanuts. When started, the machine vibrates the screen, pouring peanuts into a storage bin. The bin is designed to rise from low to high; under gravity, the peanuts flow into the screen surface, where the screen vibrates to separate them. Unqualified peanuts are discharged from the bottom through the screen holes, while qualified peanuts are discharged upwards. However, the relatively high height of the storage bin makes it difficult for workers to add peanuts, and the limited capacity necessitates frequent additions, increasing workload and fatigue. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing peanut screening machines, such as the high height of the storage bin, which makes it difficult for workers to add peanuts, and the limited storage capacity of the bin, which leads to frequent peanut additions, increasing the workload and fatigue of workers. The proposed peanut screening machine addresses these issues.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: It includes a peanut screening machine body, a storage compartment installed on the upper surface of the peanut screening machine body, a screen installed on the inner wall of the peanut screening machine body, an adjustment device on one side of the peanut screening machine body, the adjustment device including two fixed rods, the two fixed rods being fixedly connected to both ends of the side of the peanut screening machine body respectively, a common placement plate being fixedly connected to one end of the arc surface of the two fixed rods approaching each other, a cylinder being fixedly connected to one side of the placement plate, a push plate being fixedly connected to the output end of the cylinder, a conveying hole being opened on the bottom wall of the placement plate, a motor being fixedly connected to one end of the peanut screening machine body, and three adjustment plates being fixedly connected to the output end of the motor.

[0007] The aforementioned components achieve the following effects: The peanut screening machine body is a mechanical device used in peanut processing for screening, cleaning, and sorting peanuts. When the machine body is started, it vibrates the screen, pouring peanuts into the storage bin. The storage bin is designed from low to high; under the influence of gravity, the peanuts flow into the screen surface. The screen vibration then separates the peanuts. Unqualified peanuts are discharged from the bottom of the machine body through the screen holes, while qualified peanut fragments are discharged along the direction of the machine body. However, the storage bin is designed to be quite high, making it difficult for workers to add peanuts. Furthermore, the storage capacity is limited, requiring frequent additions, increasing workload and fatigue. An adjustment device can be used to add peanuts to the storage bin, improving convenience, reducing workload, and minimizing worker fatigue.

[0008] Preferably, a guide plate is fixedly connected to the side of the conveying hole near the motor, and the cross-section of the guide plate is circular.

[0009] The effect achieved by the above-mentioned components is that when peanuts are conveyed into the storage bin through the conveying hole, the guide plate installed on one side of the conveying hole can improve the accuracy of the peanuts falling and improve the stability of the peanuts falling into the storage bin.

[0010] Preferably, an auxiliary box, which is a plastic box, is slidably connected to one side of the two fixed rods.

[0011] The effect achieved by the above-mentioned components is that when peanuts are poured into the placement plate, the auxiliary box placed on the fixing rod can collect the peanuts that slip out, preventing the peanuts from falling from the placement plate to the ground.

[0012] Preferably, handles are fixedly connected to both sides of the auxiliary box.

[0013] The effect achieved by the above components is that when it is necessary to pick up the auxiliary box, the auxiliary box can be picked up by the handle installed on the auxiliary box, which can increase the speed of picking up the auxiliary box.

[0014] Preferably, an auxiliary device is provided on the side of the peanut screening machine body near the storage compartment. The auxiliary device includes two connecting rods, both of which are fixedly connected to the peanut screening machine body. A groove is formed at one end of the arc surface of each connecting rod. The same guide rod is fixedly connected to both sides of the inner wall of the groove. An adjusting rod is slidably connected to the arc surface of the guide rod. The arc surfaces of the two adjusting rods are rotatably connected to the same roller. Several protrusions are fixedly connected to the arc surface of the roller. The several protrusions are evenly distributed on the arc surface of the roller. The roller is slidably connected to the screen. A rotating rod is threaded through the inner wall of one of the connecting rods. The rotating rod is threadedly connected to the inner wall of one of the adjusting rods.

[0015] The effect achieved by the above-mentioned components is as follows: After the peanut screening machine body is used, a lot of peanut grains or impurities will be stuck in the screen holes. At this time, the auxiliary device can be used to clean the screen surface, thereby cleaning the screen holes, improving the flow of the screen, and improving the subsequent use effect of the screen.

[0016] Preferably, one end of the arc surface of one of the adjusting rods is fixedly connected to a rotating block, and the rotating block has a circular cross-section.

[0017] The effect achieved by the above components is that when the roller slides on the guide rod by the adjusting rod, the rotating block installed on the adjusting rod can increase the speed of rotating the adjusting rod and improve the stability of the roller's movement.

[0018] Preferably, the arc surface of the rotating block is provided with a plurality of auxiliary grooves, and the plurality of auxiliary grooves are evenly distributed on the arc surface of the rotating block.

[0019] The effect achieved by the above components is that when the adjusting rod is driven to move by the rotating block, the auxiliary groove on the rotating block can increase the friction on the surface of the rotating block, thereby improving the efficiency of driving the adjusting rod to move by the rotating block.

[0020] In summary, the beneficial effects of this utility model are as follows:

[0021] In this invention, by operating the adjustment device, peanuts can be added to the peanut screening machine. The adjustment device can improve the convenience of adding peanuts, reduce the fatigue of workers when adding peanuts, and reduce the difficulty of the workers' work.

[0022] In this invention, by operating the auxiliary device, after the screen in the peanut screening machine has been used, the screen holes of the screen can be rolled by the auxiliary device, thereby clearing the screen holes and improving the subsequent use effect of the screen and the screening effect of the peanut screening machine in screening peanuts.

[0028] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0029] Reference Figures 1-4 As shown, this utility model provides a technical solution: a peanut screening machine, including a peanut screening machine body 1, a storage bin 4 installed on the upper surface of the peanut screening machine body 1, a screen 5 installed on the inner wall of the peanut screening machine body 1, an adjustment device 2 provided on one side of the peanut screening machine body 1, and an auxiliary device 3 provided on the side of the peanut screening machine body 1 near the storage bin 4.

[0030] The specific settings and functions of its adjustment device 2 and auxiliary device 3 will be described in detail below.

[0031] Reference Figure 2 and Figure 3As shown in this embodiment: the adjusting device 2 includes two fixed rods 201, which are respectively fixedly connected to both ends of the side of the peanut screening machine body 1. A common placement plate 202 is fixedly connected to one end of the arc-shaped surface of the two fixed rods 201 that are close to each other. A cylinder 203 is fixedly connected to one side of the placement plate 202. A push plate 204 is fixedly connected to the output end of the cylinder 203. A conveying hole 206 is opened on the bottom wall of the placement plate 202. A motor 207 is fixedly connected to one end of the peanut screening machine body 1. Three adjusting plates 205 are fixedly connected to the output end of the motor 207. 1 is a type of mechanical equipment used in peanut processing for screening, cleaning, and sorting peanuts. Typically, when the peanut screening machine body 1 is started, it causes the screen 5 to vibrate, pouring peanuts into the storage bin 4. The storage bin 4 is designed from low to high; under the influence of gravity, the peanuts flow into the surface of the screen 5. The vibration of the screen 5 then screens the peanuts. Unqualified peanuts are discharged from the bottom of the peanut screening machine body 1 through the screen holes, while qualified peanut fragments are discharged along the direction of the peanut screening machine body 1. However, the storage bin 4 of this peanut screening machine body 1 is designed to be quite high, which increases the processing time. Adding peanuts to the storage bin 4 is difficult for workers due to its limited capacity, requiring frequent additions and increasing their workload and fatigue. Adjustment device 2 can be used to improve the ease of adding peanuts, reducing workload and fatigue. A guide plate 208 is fixedly connected to the side of the conveying hole 206 near the motor 207. The guide plate 208 has a circular cross-section. When peanuts are conveyed into the storage bin 4 through the conveying hole 206, the guide plate 208 on one side of the conveying hole 206 can improve the flow of peanuts. To improve the accuracy of the falling peanuts and enhance their stability when they fall into the storage compartment 4, an auxiliary box 209 is slidably connected to one side of each of the two fixed rods 201. The auxiliary box 209 is a plastic box. When the peanuts are poured into the placement plate 202, the auxiliary box 209 placed on the fixed rods 201 can collect any peanuts that slip out, preventing them from falling from the placement plate 202 to the ground. Handles 210 are fixedly connected to both sides of the auxiliary box 209. When it is necessary to retrieve the auxiliary box 209, it can be retrieved through the handles 210 installed on the auxiliary box 209, which can increase the speed of retrieving the auxiliary box 209.

[0032] Reference Figure 4As shown in this embodiment: the auxiliary device 3 includes two connecting rods 31, both of which are fixedly connected to the peanut screening machine body 1. A groove 32 is provided at one end of the arc surface of each connecting rod 31. A guide rod 33 is fixedly connected to both sides of the inner wall of the groove 32. An adjusting rod 34 is slidably connected to the arc surface of the guide rod 33. A roller 35 is rotatably connected to the arc surfaces of the two adjusting rods 34. Several protrusions 36 are fixedly connected to the arc surface of the roller 35, and these protrusions 36 are evenly distributed on the arc surface of the roller 35. The roller 35 is slidably connected to the screen 5. A rotating rod 37 is threaded through the inner wall of one of the connecting rods 31, and the rotating rod 37 is threadedly connected to the inner wall of one of the adjusting rods 34. After the peanut screening machine body 1 is used, a large number of peanut grains or impurities may be stuck in the screen holes of the screen 5. At this time, the auxiliary device 3 can be used to clean the surface of the screen 5. The auxiliary device 3 is used to clean the screen holes of the screen 5, thereby improving the flow rate of the screen holes and enhancing the subsequent performance of the screen 5. One end of the arc surface of the adjusting rod 34 is fixedly connected to a rotating block 38. The rotating block 38 has a circular cross-section. When the adjusting rod 34 drives the roller 35 to slide on the guide rod 33, the rotating block 38 installed on the adjusting rod 34 can increase the speed of the adjusting rod 34 and improve the stability of the roller 35. The arc surface of the rotating block 38 is provided with several auxiliary grooves 39, which are evenly distributed on the arc surface of the rotating block 38. When the adjusting rod 34 is driven by the rotating block 38, the auxiliary grooves 39 on the rotating block 38 can increase the friction of the rotating block 38 surface, thereby improving the efficiency of the adjusting rod 34 being driven by the rotating block 38.

[0033] Detailed Instructions for Use: Pour the peanuts into the placement plate 202. Then, start the cylinder 203. The movement of the cylinder 203 will cause the push plate 204 to slide within the placement plate 202, thus pushing the peanuts into the other side of the adjusting plate 205. At this time, start the motor 207. The movement of the motor 207 will drive the adjusting plate 205 to rotate through its output end. The movement of the adjusting plate 205 will cause the peanuts on the push plate 204 to rotate within the placement plate 202 until the peanuts flow into the storage chamber 4 through the conveying hole 206, thus completing the peanut addition task.

[0034] Rotate the rotating rod 37 on the adjusting rod 34 to remove the rotating rod 37 from the adjusting rod 34. At this time, the fixing effect on the adjusting rod 34 can be released, and the roller 35 can be driven to move on the guide rod 33 via the adjusting rod 34. The movement of the roller 35 will cause the protrusion 36 to contact the screen hole of the screen 5, thereby clearing the screen hole under the action of the protrusion 36.
