Description

Technical Field

[0001] This invention relates to the field of peanut material cleaning technology, and in particular to a peanut side soil removal device. Background Technology

[0002] In hilly and mountainous areas, peanuts are grown in heavy clay soil. After harvest, the peanut pods contain a large number of adjacent soil clumps. Since the size of the soil clumps is close to that of the peanut pods, it makes cleaning and grading the peanut pods after harvesting extremely difficult. In the existing technology, the main way to remove adjacent soil or adjacent stones from grain is to use an inclined vibrating screen. For example, patent CN 206168805 U has an inclined destone screen plate with serrations. When the destone screen plate vibrates, the serrations push the destone screen plate upward, while the grain moves downward along the destone screen plate, so that the grain and adjacent stones are discharged from both sides of the destone screen plate, thus achieving the destone removal function. Patents CN209124383U and CN2832333Y also use similar solutions. The above solutions have the following defects: (1) This destone removal device is mainly suitable for destone removal of small grain particles, and its effect on removing adjacent soil impurities from peanuts is poor. (2) It is mainly suitable for destone operations. For peanuts, the soil clods are easily crushed by the saw teeth and fall into the peanuts, resulting in small soil clods mixed in with the peanuts. Further cleaning is required to remove the small soil clods, which increases the number of processes and reduces efficiency. (3) It can only be used for destone operations and cannot process other impurities at the same time. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, the present invention provides a peanut soil removal device with simple structure, high efficiency and good separation effect.

[0004] Technical solution: To achieve the above objectives, the peanut soil removal device of the present invention includes a separation cylinder in the shape of a cylinder body and an air suction mechanism connected to the separation cylinder body. The air suction mechanism has an airflow outlet. A suction pipe is connected to the side wall of the separation cylinder body, and a discharge port is provided at the bottom of the separation cylinder body. A release mechanism is installed at the discharge port.

[0005] Furthermore, the release mechanism includes a plate, which is rotatably connected to the discharge port via a rotating shaft. A counterweight is mounted on the rotating shaft, offset relative to the rotation axis of the plate, causing the plate to rotate relative to the discharge port to seal it. After a sufficiently heavy load of peanut pods accumulates on the plate, the material can force the plate open for unloading. Specifically, the rotating shaft includes a hinged rod and a mounting rod for mounting the counterweight. The two rods are arranged in an L-shape, with the mounting rod and the plate located on opposite sides of the hinged rod. The counterweight can be adjusted relative to the mounting rod to regulate the release force of the release mechanism.

[0006] In operation, the release mechanism keeps the discharge port normally closed. The mixture containing peanut pods, soil, and light impurities moves under the suction pipe opening through the vibrating screen or conveying mechanism. The operation of the air suction mechanism creates negative pressure inside the separation cylinder, thereby generating suction at the suction pipe opening. This air suction draws the peanut pods and light impurities away from the material, allowing them to enter the separation cylinder, leaving only the soil to continue moving with the vibrating screen or conveying mechanism. Among the peanut pods and light impurities inside the separation cylinder, the light impurities, due to their light weight, are further drawn into the air suction mechanism and discharged from its airflow outlet. The peanut pods, due to their greater weight, fall to the bottom of the separation cylinder and accumulate above the plate. When the accumulated peanut pods on the plate are sufficient to rotate the counterweight, the peanut pods push the plate open, allowing some of the peanut pods to be unloaded. The plate, which is normally closed, allows the separation cylinder to generate sufficient negative pressure when the air suction mechanism is running, so that the inlet of the suction pipe can generate sufficient suction force, thereby reducing energy consumption.

[0007] Furthermore, the air suction mechanism is located at the top of the separation cylinder, and includes a centrifugal fan and a motor that drives the centrifugal fan. During use, the speed of the motor is adjusted so that the suction force generated at the inlet of the suction pipe can suck up the peanut pods and light impurities in the mixture and leave the soil behind. The upper side of the separation cylinder has an inner cylinder connected to the centrifugal fan. The lower part of the inner cylinder is open. The suction pipe is connected to the upper side wall of the separation cylinder, and the lower end of the inner cylinder is lower than the upper section of the suction pipe. In addition, the upper section of the suction pipe is offset from the central axis of the separation cylinder.

[0008] After peanut pods and light impurities enter the separation cylinder, the peanut pods, being heavier, are thrown off by centrifugal force. The inner cylinder separates the peanut pods from the outside, preventing them from entering the centrifugal fan. The light impurities are drawn upwards from the bottom of the inner cylinder by the centrifugal fan and discharged through the inner cylinder and the centrifugal fan, thus achieving effective separation of peanut pods and light impurities.

[0009] Furthermore, the lower end of the suction pipe has a square section, and the upper end has a circular section, with a transition section connecting the circular section and the square section. The opening of the square section is elongated, allowing it to pick up peanut pods and light impurities over a relatively wide area. After passing through the transition section, the picked-up material is gathered and enters the circular section, thus preventing the material entering the separation cylinder from becoming overly dispersed and affecting the separation effect.

[0010] Furthermore, the square tube segment has an adjustable tube segment below it, which is capable of telescoping relative to it. An adjusting screw is installed on the adjustable tube segment, and the lower end of the square tube segment has a slotted hole in which the adjusting screw slides. A locking nut is also included to lock the relative position of the square tube segment and the adjustable tube segment. The cross-sectional shape of the adjustable tube segment is a long rectangular shape consistent with the cross-sectional shape of the square tube segment.

[0011] Correspondingly, the aforementioned mixture is thrown forward by the screen body that swings along an arc trajectory, so that the mixture can be intermittently thrown up and passed through the lower end of the adjustable tube section. By adjusting the position of the lower end of the adjustable tube section, the position of the lower end of the adjustable tube section can be adapted to the highest position where the material can be thrown. This not only does not obstruct the movement of the mixture, but also picks up the peanut pods and light impurities in time. Moreover, the material thrown into the air is more easily picked up by the lower end of the adjustable tube section.

[0012] Furthermore, the lower end of the separating cylinder has a lower cone that gathers peanut pods to the discharge port.

[0013] Beneficial effects: The peanut soil removal device of the present invention has the following beneficial effects:

[0014] (1) It can separate peanut pods, light impurities and soil in a mixture in one go. It has a simple structure, low cost and good separation effect, and can obtain clean peanut pods in one go.

[0015] (2) By using the method of sucking away peanut pods and leaving soil behind, the problem of traditional stone removal screen plate functional unit being unsuitable for mud removal can be effectively solved. Furthermore, after sucking away peanut pods, the problem of removing light impurities can be solved at the same time. Attached Figure Description

Detailed Implementation

[0021] The invention will now be further described with reference to the accompanying drawings.

[0022] like Figures 1-2 The peanut soil removal device shown includes a cylindrical separation cylinder 1 and an air suction mechanism 2 connected to the separation cylinder 1. The air suction mechanism 2 has an airflow outlet 21. A suction pipe 3 is connected to the side wall of the separation cylinder 1, and a discharge port 4 is located at the bottom of the separation cylinder 1. The discharge port 4 is a shell that runs vertically through the body, and a release mechanism 5 is installed at the discharge port 4. The lower end of the separation cylinder 1 has a lower cone 12 that gathers peanut pods to the discharge port 4.

[0023] The release mechanism 5 includes a plate 51, which is rotatably connected to the discharge port 4 via a rotating shaft 52. A counterweight 53 is mounted on the rotating shaft 52, and the counterweight 53 is offset relative to the rotation axis of the plate 51, causing the plate 51 to rotate relative to the discharge port 4 to block it. After a sufficiently heavy amount of peanut pods accumulates on top of the plate 51, the peanut pods can push the plate 51 open for unloading. Specifically, the rotating shaft 52 includes a hinged rod and a mounting rod 5b for mounting the counterweight 53. The two rods are arranged in an L-shape, with the mounting rod and the plate 51 located on opposite sides of the hinged rod 5a. The counterweight 53 can be adjusted relative to the mounting rod 5b to adjust the release force of the release mechanism 5.

[0024] In use, the release mechanism 5 keeps the discharge port 4 in a normally closed state. The mixture containing peanut pods, soil, and light impurities moves under the influence of a vibrating screen or conveying mechanism, passing below the opening of the suction pipe 3. The operation of the air suction mechanism 2 creates a negative pressure inside the separation cylinder 1, thereby generating suction at the opening of the suction pipe 3. The air suction removes the peanut pods and light impurities from the material, allowing them to enter the separation cylinder 1, leaving only the soil to continue moving with the vibrating screen or conveying mechanism. Among the peanut pods and light impurities entering the separation cylinder 1, the light impurities, due to their light weight, are sucked into the air suction mechanism 2 and discharged from the airflow outlet 21 of the air suction mechanism 2. The peanut pods, due to their large weight, fall to the bottom of the separation cylinder 1 and accumulate above the plate 51. When the accumulated peanut pods on the plate 51 are sufficient to rotate the counterweight 53, the peanut pods push the plate 51 open, achieving partial unloading of the peanut pods. The plate 51, which is in a normally closed state, allows the separation cylinder 1 to generate sufficient negative pressure when the air suction mechanism 2 is running, so that the inlet of the suction pipe 3 can generate sufficient suction force, thereby reducing energy consumption.

[0025] It is evident that the above-mentioned side soil removal device can achieve the separation of peanut pods, light impurities, and side soil in a mixture in one operation. It has a simple structure, low cost, and good separation effect.

[0026] Preferably, the air suction mechanism 2 is located at the top of the separation cylinder 1, and includes a centrifugal fan 22 and a motor 23 that drives the centrifugal fan 22. During use, the speed of the motor 23 is adjusted so that the suction force generated at the opening of the suction pipe 3 can suck up the peanut pods and light impurities in the mixture, leaving behind the soil. Figure 3 As shown, the upper side of the separation cylinder 1 has an inner cylinder 11 connected to the centrifugal fan 22. The lower end of the inner cylinder 11 is open and its four walls are airtight. The suction pipe 3 is connected to the inlet located on the upper side of the side wall of the separation cylinder 1. The lower end of the inner cylinder 11 is lower than the inlet. In addition, the upper pipe section of the suction pipe 3 connected to the inlet is offset from the central axis of the separation cylinder 1, so that the direction of material entering the separation cylinder 1 is offset from the central axis of the separation cylinder 1.

[0027] After peanut pods and light impurities enter the separation cylinder 1, the peanut pods, being heavier, are thrown off by centrifugal force. The inner cylinder 11 separates the peanut pods from the outside, preventing them from entering the centrifugal fan 22. The light impurities are drawn upward from the lower end of the inner cylinder 11 by the centrifugal fan 22 and discharged through the inner cylinder 11 and the centrifugal fan 22, thus achieving effective separation of peanut pods and light impurities.

[0028] The lower end of the suction pipe 3 has a square pipe section 31, and the upper end has a circular pipe section 32. A transition pipe section 33 connects the circular pipe section 32 and the square pipe section 31. The opening of the square pipe section 31 is elongated, which allows it to suck up peanut pods and light impurities over a relatively wide area. After passing through the transition pipe section 33, the sucked-up material is gathered and enters the circular pipe section 32. This prevents the material entering the separation cylinder 1 from being overly dispersed and affecting the separation effect.

[0029] Below the square tube section 31 is an adjustable tube section 34 that can be extended or retracted relative to it. An adjusting screw 35 is mounted on the adjustable tube section 34. Figure 4 As shown, the lower end of the square tube segment 31 has a strip-shaped hole 31a in which the adjusting screw 35 slides, and also includes a locking nut 36 for locking the relative position of the square tube segment 31 and the adjustable tube segment 34. The cross-sectional shape of the adjustable tube segment 34 is a long rectangular shape that is consistent with the cross-sectional shape of the square tube segment 31.

[0030] Correspondingly, the aforementioned mixture is thrown forward by the screen body 6, which swings along the arc trajectory a, so that the mixture can be intermittently thrown up through the lower end of the adjustable tube section 34. By adjusting the position of the lower end of the adjustable tube section 34, the position of the lower end of the adjustable tube section 34 can be adapted to the highest position where the material can be thrown. This not only does not obstruct the movement of the mixture, but also picks up the peanut pods and light impurities in time. Moreover, the material thrown into the air is more easily picked up by the lower end of the adjustable tube section 34.

[0031] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
