The shape of the picking rod is set to be wavy, and limit blocks are provided at both ends of the picking rod. The inner side of the turntable is fixedly connected to a card block, and the limit block is embedded in the card block. Screw holes are provided on the side of the picking rod. In the above application documents, when personnel manually reach into the device to put peanuts for processing, the device inside the device has a certain traction force on the peanut root bundle during the process of separating the peanuts from the peanut root bundle, which not only has high labor intensity, but also has certain safety hazards. At the same time, the device has certain deficiencies in screening peanuts and soil, and the overall effect needs to be improved. Summary of the invention

[0004] In order to solve the problem of personnel safety in the prior art, the present invention proposes a light, low-resistance and high-effect stem separation device, which can drive peanuts to be processed in the equipment through automatic clamping and movement, so as to reduce labor intensity and reduce safety hazards.

[0005] A light, simple, low-resistance and high-effect stem separation device comprises a main frame, a motor is arranged on the side of the main frame, a turntable 1 and a turntable 2 are rotatably connected inside the main frame, and a breaking rod is fixedly connected to the opposite surfaces of the turntable 1 and the turntable 2;

[0006] A propulsion device is provided at the top of the breaking rod, and the propulsion device includes a positioning plate, one end of the positioning plate is fixedly connected to the inner wall of the main frame, and the other end of the top surface of the positioning plate is fixedly connected to the limiting plate, and gear 1 is provided at both the front and rear ends of the limiting plate, and the gear 1 and the surface of the limiting plate are connected to pulley 1 in a transmission manner, and the outer surface of the pulley 1 is fixedly connected to connecting plate 1, and the surface of the connecting plate 1 is connected to an arc-shaped notch wheel 1 in a transmission manner, and the rear end of the arc-shaped notch wheel 1 is provided with gear 2, and the surface of the gear 2 is connected to pulley 2 in a transmission manner, and the outer surface of the pulley 2 is fixedly connected to connecting plate 2, and the surface of the connecting plate 2 is connected to arc-shaped notch wheel 2 in a transmission manner.

[0007] Furthermore, an extrusion device is provided on the surface of the arc-shaped slot wheel 2, and the extrusion device includes a positioning block, one end of the positioning block is fixedly connected to the surface of the arc-shaped slot wheel 2, and the other end of the positioning block is provided with a pressing plate, and a soft capsule 1 is fixedly connected to the central surface of the side of the pressing plate away from the positioning block, the surface of the soft capsule 1 is fitted with the surface of the arc-shaped slot wheel 1, and soft capsule 2 is provided at both ends of the soft capsule 1.

[0008] Furthermore, a screening device is provided inside the main frame, and the screening device includes a screening plate, the rear end of the screening plate is hinged to the rear end inner wall of the main frame, the front end surface of the screening plate penetrates the inner wall of the discharge trough, and an airbag 2 is provided at the bottom of the screening plate, the rear end of the airbag 2 is fixedly connected to the rear end inner wall of the main frame, and a baffle is provided on the top of the screening plate, and the surface of the baffle is fixedly connected to the surface of turntable 1.

[0009] Furthermore, a discharge trough is provided on the front end surface of the main frame, and a mud receiving box is provided on the bottom side of the main frame, so that the screened peanuts can fall out of the main frame smoothly. The position of the discharge trough is on the front end surface of the main frame, which facilitates the collection and movement of the screened materials and improves the efficiency of the entire screening system.

[0010] Furthermore, the top of the gear one is rotatably connected to a support rod, and the end of the support rod away from the gear one is fixedly connected to the surface of the limit plate. The fixed connection of the support rod makes it less likely for the top of the gear one to shake or shift during operation, thereby improving the stability of the entire system. By fixing the support rod to the surface of the limit plate, the movement range of the gear one can be limited, ensuring that it only moves on a designed trajectory, thereby avoiding unnecessary failures and damages.

[0011] Furthermore, the soft capsule one and the soft capsule two are interconnected, and a card block is fixedly connected to the surface of the soft capsule two. Through the mutual penetration between the soft capsule one and the soft capsule two, fluid transfer between the two can be achieved, and the card block helps provide additional support and stability for the peanuts.

[0012] Furthermore, a square groove is provided on one side surface of the pressure plate close to the positioning block, and a hinge rod is hinged on the inner wall of the square groove, and the surface of the hinge rod is hinged to the surface of the positioning block. Airbags are fixedly connected to both side surfaces of the square groove, and the surface of the airbag fits the surface of the positioning block. A mechanical positioning is provided through the structure of the positioning block and the square groove to ensure that the pressure plate is in a specific position. The existence of the hinge rod may allow a certain degree of angular transmission, thereby realizing the adjustment of the pressure plate. Airbags are fixedly connected on both sides of the square groove to adjust the position of the pressure plate or apply pressure to it by the expansion or contraction of gas. The airbags are fixedly connected on both sides to provide uniform adjustment of the pressure plate.

[0013] Furthermore, a square plate is provided at the bottom of the baffle, and the surface of the square plate is fixedly connected to the side of the screening plate, thereby enhancing the stability and structural strength of the baffle and ensuring that the baffle will not be deformed or unstable during use. The setting of the square plate can enhance the structural stability of the baffle and, to a certain extent, enhance the stability of the connection between the baffle and the screening plate.

[0014] Furthermore, the baffle is overall in the shape of an anchor, and the baffle and square plate are both made of stainless steel. Stainless steel has excellent corrosion resistance, and the baffle and square plate can maintain a smooth surface and are not easy to rust. Stainless steel has good strength and hardness and can withstand a certain amount of force and pressure. Therefore, the baffle and square plate can provide reliable support and protection and extend their service life.

[0015] The difference from the prior art is that the beneficial effects of this application are:

[0016] (1) The light, simple, low-resistance, high-effect stem separation device drives a pulley and an arc-shaped notch wheel 2 to rotate inside a main frame through a second gear, and simultaneously moves in an arc synchronously with the arc-shaped notch wheel 1, driving the peanut root bundle to swing left and right inside the main frame, and then uses a beating rod inside the device to hit the peanuts on the peanut root bundle, thereby achieving the effect of separating the peanuts from the peanut root bundle.

[0017] (2) The light, simple, low-resistance and high-efficiency stem separation device makes the soft capsule 1 on the surface of the pressing plate contact with the peanut root bundle and squeeze it on the arc-shaped groove wheel 1, and the gas inside the soft capsule 2 flows into the soft capsule 2 on both sides to make it bulge, wrapping the peanut root bundle, and then uses the block on the surface to position and clamp the peanut root bundle, so as to achieve the effect of helping the peanuts to move stably when moving.

[0018] (3) The light, low-resistance, high-efficiency stem separation device drives the baffle to knock on the square plate on the side of the screening plate through the rotation of the turntable 1, causing the screening plate to sag and squeezing the airbag 2 at the bottom. When the baffle loses the knock on the screening plate, the bulging of the airbag 2 is used to reset the screening plate, helping the screening plate to vibrate up and down inside the main frame, thereby achieving the effect of helping to classify peanuts and soil.

[0041] A propulsion device 500 is provided on the top of the scattering rod 800, and the propulsion device 500 includes a positioning plate 505, one end of the positioning plate 505 is fixedly connected to the inner wall of the main frame 100, and a discharging trough 1000 is provided on the front end surface of the main frame 100, so that the peanuts after screening can fall out of the main frame 100 smoothly, and a mud receiving box 300 is provided on the bottom side of the main frame 100 to collect the separated mud, and the position of the discharging trough 1000 is on the front end surface of the main frame 100, which is convenient for collecting and moving the screened materials and improving the efficiency of the entire screening. The top surface of the other end of the positioning plate 505 is fixedly connected to the limiting plate 506, and the front and rear ends of the limiting plate 506 are both provided with a gear 507, and the top of the gear 507 is rotatably connected to a support rod 508, and the end of the support rod 508 away from the gear 507 is fixedly connected to the surface of the limiting plate 506 , the fixed connection of the support rod 508 makes it difficult for the top of the gear 1 507 to shake or deviate during operation, thereby improving the stability of the entire system; the support rod 508 is fixedly connected to the surface of the limit plate 506, so that the movement range of the gear 1 507 can be limited to ensure that it only moves on the designed trajectory, avoiding unnecessary failures and damages; the surface transmission connection of the gear 1 507 and the limit plate 506 is connected with a pulley 1 511; the outer surface of the pulley 1 511 is fixedly connected with a connecting plate 1 509; the surface transmission connection of the connecting plate 1 509 is connected with an arc-shaped notched wheel 1 510; the rear end of the arc-shaped notched wheel 1 510 is provided with a gear 2 501; the surface transmission connection of the gear 2 501 is connected with a pulley 2 502; the outer surface of the pulley 2 502 is fixedly connected with a connecting plate 2 503; the surface transmission connection of the connecting plate 2 503 is connected with an arc-shaped notched wheel 2 504.

[0042] When in use, the personnel first controls the starting motor 200 to work, driving the turntable 2 400 and the turntable 1 900 inside the main frame 100 to rotate synchronously. Here, it is explained that the turntable 2 400 and the turntable 1 900 are used to drive the breaking rod 800 to work, and at the same time, the top of the main frame 100 drives the gear 2 501 to rotate inside the main frame 100 through the starting block, and after the rotation, it drives the synchronous rotation of the surface pulley 2 502 and the arc-shaped notch wheel 2 504. Here, it is explained that the pulley 2 502 drives the arc-shaped notch wheel 2 504 through the connecting plate 2 503, and at the same time, the arc-shaped notch wheel 1 510 is used on one side to cooperate, so that the peanut root bundle can be placed on the arc-shaped notch wheel 1 510 and then the arc-shaped notch wheel 2 504 is rotated. The peanut root bundle is driven to move along the arc-shaped notched wheel 1 510 by extrusion. During the movement of the peanut root bundle, the peanuts on the peanut root bundle are knocked down to the inside of the main frame 100 by the rotation of the scattering rod 800. When it moves to the rear end of the arc-shaped notched wheel 1 510, the arc-shaped notched wheel 2 504 loses the extrusion on the peanut root bundle, and the peanut root bundle will automatically break away from the arc-shaped notched wheel 1 510. It is explained here that the movement distance of the arc-shaped notched wheel 2 504 is shorter than that of the arc-shaped notched wheel 1 510, so as to facilitate the automatic falling off of the peanuts after the processing is completed. At the same time, the arc-shaped equipment of the arc-shaped notched wheel 1 510 and the arc-shaped notched wheel 2 504 can achieve the effect of shaking the peanuts left and right when they move inside the main frame 100 to enhance the scattering effect.

[0043] At the same time, in order to stably clamp the peanuts, please refer to Figure 1-Figure 8As shown in the figure, the surface of the arc-shaped notch wheel 504 is provided with an extrusion device 600, and the extrusion device 600 includes a positioning block 601, one end of the positioning block 601 is fixedly connected to the surface of the arc-shaped notch wheel 504, and the other end of the positioning block 601 is provided with a pressing plate 608, and the central surface of the pressing plate 608 away from the positioning block 601 is fixedly connected with a soft capsule 1 602, and the soft capsule 1 602 and the soft capsule 2 604 are interconnected, and the surface of the soft capsule 2 604 is fixedly connected with a clamping block 603, and the fluid transfer between the soft capsule 1 602 and the soft capsule 2 604 can be achieved through the mutual penetration between the soft capsule 1 602 and the soft capsule 2 604, and the clamping block 603 helps to provide additional support and stability for the peanuts, and the surface of the soft capsule 1 602 is in contact with the surface of the arc-shaped notch wheel 510, and the pressing plate 608 is close to the positioning block 601. A square groove 606 is provided on one side surface, and a hinge rod 605 is hinged on the inner wall of the square groove 606. The surface of the hinge rod 605 is hinged on the surface of the positioning block 601. Airbags 1 607 are fixedly connected to the two side surfaces of the square groove 606. The surface of airbags 1 607 fits the surface of the positioning block 601. The structure of the positioning block 601 and the square groove 606 provides mechanical positioning to ensure that the pressure plate 608 is in a specific position. The existence of the hinge rod 605 may allow a certain degree of angular transmission, thereby realizing the adjustment of the pressure plate 608. Airbags 1 607 are fixedly connected on both sides of the square groove 606. The position of the pressure plate 608 is adjusted or pressure is applied to it by the expansion or contraction of the gas. The airbags are fixedly connected on both sides, which may provide uniform adjustment of the pressure plate 608. Soft capsules 2 604 are provided at both ends of soft capsule 1 602.

[0044] During use, after the personnel put the peanut root bundle on the surface of the arc-shaped notch 1 510, the peanut root bundle is squeezed by the pressing plate 608 on the surface of the arc-shaped notch 2 504. Here, the positioning block 601 is fixed on the surface of the arc-shaped notch wheel 2 504, and the soft capsule 1 602 on the surface of the pressing plate 608 is in contact with the peanut root bundle and squeezed. At the same time, the gas inside the soft capsule 1 602 flows into the soft capsule 2 604 on both sides to make it bulge, and the peanut root bundle is clamped by the clamping block 603 on its surface to help the peanut move stably during the movement. Here, the pressing plate 608 and the positioning block 601 are connected by a hinge rod 605 to help the peanuts to be slightly adjusted in angle when in contact with the peanuts to adapt to the different angles of the peanut root bundle. At the same time, the air bag 1 607 is used on both sides of the hinge rod 605 to clamp the two sides of the positioning block 601, so as to help the positioning block 601 to reset after the peanut root bundle is squeezed.

[0045] Also, to separate the peanuts from the soil, please refer to Figure 1-Figure 8As shown in the figure, a screening device 700 is arranged inside the main frame 100, and the screening device 700 includes a screening plate 704, the rear end of the screening plate 704 is hinged to the rear end inner wall of the main frame 100, the front end surface of the screening plate 704 penetrates the inner wall of the discharge trough 1000, and the bottom of the screening plate 704 is provided with an air bag 2 706, and the rear end of the air bag 2 706 is fixedly connected to the rear end inner wall of the main frame 100, and the top of the screening plate 704 is provided with a baffle 701, and the bottom of the baffle 701 is provided with a square plate 705, and the surface of the square plate 705 is fixedly connected to the side of the screening plate 704, which can enhance the stability and structural strength of the baffle 701 and ensure that the baffle 701 is in use. No deformation or instability will occur. The setting of the square plate 705 can enhance the structural stability of the baffle 701 and to a certain extent enhance the connection stability between the baffle 701 and the screening plate 704. The baffle 701 is in the shape of an anchor as a whole. The baffle 701 and the square plate 705 are both made of stainless steel. The stainless steel material has excellent corrosion resistance. The baffle 701 and the square plate 705 can maintain a smooth surface and are not easy to rust. The stainless steel material has good strength and hardness and can withstand a certain amount of force and pressure. Therefore, the baffle 701 and the square plate 705 can provide reliable support and protection and extend their service life. The surface of the baffle 701 is fixedly connected to the surface of the turntable 900.

[0046] When in use, when peanuts and soil fall onto the screening plate 704 of the main frame 100, the rotation of the turntable 1 900 drives the baffle plate 701 to rotate synchronously. When the baffle plate 701 rotates, its bottom squeezes and collides with the square plate 705 on the side of the screening plate 704, and the screening plate 704 is pressed downward with the rear end hinge on the inner wall of the main frame 100 as the center. At the same time, when the turntable 1 900 rotates one circle to drive the baffle plate 701 to separate from the square plate 705, the air bag 2 706 at the bottom of the screening plate 704 rebounds to restore it to its original position. It is explained here that when the screening plate 704 moves downward, its bottom squeezes the air bag 2 706. After the screening plate 704 loses its downward force, the air bag 2 706 rebounds to screen and vibrate the peanuts and soil on the surface of the screening plate 704. The screened soil enters the mud receiving box 300 at the bottom for collection, and the peanuts fall out through the discharge trough 1000 at the front end of the main frame 100.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
