[0002] Peanut is an important economic crop in my country, with a large planting area. In recent years, the area of ​​mechanized harvesting operations has also been increasing. The structures of peanut harvesters are diverse. Among them, China Patent No. ZL202322028149.8 discloses a peanut harvester. In actual operation, there are the following problems: Since peanut harvesters are usually towed by tractors, if the tractor travels at a fast speed, the time for peanuts and soil blocks to pass through the soil crushing roller when they are transported from the rear end of the shovel to the conveyor chain ladder will also be very fast. The floating soil crushing roller arranged above the rear side of the shovel has a poor effect on crushing the soil blocks on the peanuts. If the tractor travels at a low speed, the harvesting time will be delayed. Therefore, it is urgent to further set a soil crushing mechanism on the peanut harvester. Utility Model Content

[0003] In order to solve the deficiencies in the prior art, the utility model provides a peanut harvester soil crushing and seedling-pulling integrated double roller device which can improve the soil crushing effect while ensuring the harvesting efficiency.

[0004] In order to solve the above technical problems, the utility model adopts the following technical scheme: a peanut harvester soil crushing and seedling removing integrated roller device comprises a frame, a fixed roller and a floating roller which are both arranged in the left and right directions are rotatably provided on the rear side of the frame, the floating roller is located above the rear of the fixed roller, the left and right ends of the fixed roller are respectively rotatably connected to the left and right sides of the frame, a rocker arm is rotatably provided on the left and right sides of the frame through a fixed shaft, the fixed shaft is located above the fixed roller, the two rockers are arranged in parallel, the left end of the central axis of the floating roller is rotatably connected to the rear end of the left rocker arm, the right end of the central axis of the floating roller is rotatably connected to the rear end of the right rocker arm, a baffle located on the left side of the fixed roller and the floating roller is provided on the left side of the frame, a baffle located on the right side of the fixed roller and the floating roller is provided on the right side of the frame, an arc hole for passing the central axis of the floating roller is opened on the baffle, the center of the arc hole is on the center line of the fixed shaft, a tension spring is connected to the rear end of the rocker arm, the tension spring is tilted with the front high and the rear low, the rear lower end of the tension spring is connected to the frame, a soil crushing gap adjustment component located below the rear side of the rocker arm is provided on the frame, and the upper end of the soil crushing gap adjustment component is crimped to the bottom of the rocker arm.

[0005] The soil crushing gap adjustment assembly includes a fixing nut, a locking nut and an adjusting screw. The fixing nut is fixedly connected to the frame, the adjusting screw is vertically arranged, the lower end of the adjusting screw is threadedly connected in the fixing nut, the locking nut is threadedly connected to the adjusting screw and is crimped with the upper end of the fixing nut, a rubber cap is installed on the outside of the rod head at the upper end of the adjusting screw, and the upper end surface of the rubber cap is crimped with the bottom of the rocker arm.

[0006] The outer circles of the left and right ends of the floating roller are both provided with spiral seedling-pulling blades.

[0007] L-shaped guide plates are provided on the frame below and behind the spiral seedling-pulling blades. The two guide plates on the left and right sides have the same structure and are symmetrically arranged. The rear side of the left guide plate gradually tilts backward from left to right, and the bottom of the left guide plate gradually tilts downward from left to right.

[0008] By adopting the above technical scheme, the utility model is installed at the rear of the peanut harvester with patent number ZL202322028149.8, specifically between the lower rear end of the conveyor chain ladder and the upper front part of the vine fruit laying and turning mechanism. The gap formed between the fixed roller and the floating roller is located directly below the rear end edge of the conveyor chain ladder. The fixed roller and the floating roller of the utility model are both transmission-connected to the rear side of the conveyor chain ladder.

[0009] The working process of the utility model is as follows: under the traction of the tractor, the peanut harvester scoops up the peanuts and conveys them backwards with a blade assembly, firstly crushes the soil through the soil crushing roller on the front side of the conveying chain ladder, and then conveys them backwards and upwards through the conveying chain ladder. A rake bar is arranged on the connecting rod of the conveying chain ladder, which can further crush the soil blocks. The vibrating shaft drives the vibrating wheel to rotate, and the vibrating wheel can drive the upper half of the chain of the conveying chain ladder to shake up and down, thereby shaking off the broken soil blocks. When the peanuts are about to pass through the rightmost end of the conveying chain ladder, the roots of the peanuts still carry a certain amount of soil blocks. The peanuts and the soil blocks first fall to the front half of the floating roller, and then slide forward to the gap between the floating roller and the fixed roller. The upper part of the fixed roller rotates backward, and the upper part of the floating roller rotates forward, driving the peanuts to move downward through the gap. When the soil blocks on the peanuts are large in size, When the gap width is greater than the gap width, the floating roller overcomes the pulling force of the tension spring, rotates and floats upward with the hinge point of the front end of the rocker arm and the frame as the center, so that the soil blocks are crushed for the second time and the crushed soil falls to the ground. When the peanut vines pass through the gap, under the action of the tension spring, the floating roller rotates downward with the hinge point of the front end of the rocker arm and the frame as the center. During the working process of the secondary suppression and soil crushing device, the floating roller floats up and down continuously to perform secondary soil crushing operations. After the secondary soil crushing, the peanut vines and fruits basically carry no soil blocks and slide to the front side of the vine and fruit laying and turning mechanism. The star disk of the vine and fruit laying and turning mechanism turns the peanut vines and fruits to a state where the fruit faces up and the vines face down. The laying strips are laying grates, which guide the turned peanut vines and fruits, and cooperate with the star disk to lay the vines and fruits on the ground in the middle of the rear side of the frame. As the entire peanut harvester continues to move forward, the peanut harvesting operation is completed.

[0010] The utility model crushes soil by the soil crushing roller once, crushes soil by the rake rod arranged on the connecting rod of the conveying chain ladder through vibration, and crushes soil by the floating roller twice, so that soil blocks on the peanut seedlings are basically cleaned and the subsequent manual labor is fully reduced.

[0011] The spiral seedling-pulling blades arranged on the outer circles of the left and right ends of the floating roller rotate with the floating roller, and transport the peanut seedlings and fruits falling from the left and right ends of the conveyor chain ladder to the middle, avoiding secondary crushing through the gap between the floating roller and the fixed roller and then falling vertically to the space between the left and right sides of the front part of the seedling-turning mechanism and the frame.

[0012] The rear side of the guide plate can prevent the peanuts falling from the left and right ends of the conveyor chain ladder from sliding back to the ground without secondary soil crushing. When the spiral blades move the peanuts to the middle during rotation, when they move to the bottom of the guide plate, the bottom of the guide plate guides the peanuts to the middle, preventing them from falling directly to the ground.

[0013] The soil crushing gap adjustment assembly is to loosen the locking nut first, then turn the adjusting screw to adjust the height of the upper end of the adjusting screw, adjust the height position of the rear end of the rocker arm, and adjust the minimum gap between the soil crushing roller and the fixed roller accordingly. After the adjustment is completed, tighten the locking nut to fix the adjusting screw. The rubber cap at the upper end of the adjusting screw reduces the impact force between the rocker arm and the adjusting screw when the floating roller floats up and down, and plays a role in shock absorption and noise reduction.

[0014] In summary, the utility model adds a secondary suppression and soil crushing device on the basis of the peanut harvester with patent number ZL202322028149.8, which basically completely crushes the soil blocks on the peanut vines and fruits and separates the fruits from the soil. During the harvesting operation, the machine can move at a high speed, ensuring the efficiency of the harvesting operation while improving the soil crushing effect and reducing the subsequent manual labor intensity.

A rubber cap 23 is installed on the outside of the rod head at the upper end of the adjusting screw 22, and the upper end surface of the rubber cap 23 is crimped with the bottom of the rocker arm 15.

[0021] The outer circles of the left and right ends of the floating roller 14 are both provided with spiral seedling-moving blades 24 .

[0022] An L-shaped guide plate 25 is provided on the frame 1 below and behind the spiral seedling-moving blade 24. The two guide plates 25 on the left and right sides have the same structure and are symmetrically arranged. The rear side of the left guide plate 25 gradually tilts backward from left to right, and the bottom of the left guide plate 25 gradually tilts downward from left to right.

[0023] The utility model is installed at the rear part of the peanut harvester with patent number ZL202322028149.8, specifically between the lower part of the rear end of the conveying chain ladder 5 and the upper part of the front part of the seedling and fruit laying and turning mechanism 6. The gap formed between the fixed roller 13 and the floating roller 14 is located just below the rear end edge of the conveying chain ladder 5. The fixed roller 13 and the floating roller 14 of the utility model are both transmission-connected to the rear side of the conveying chain ladder 5.

[0024] The working process of the utility model is as follows: under the traction of the tractor, the peanut harvester scoops up the peanuts and conveys them backwards, first passing through the soil crushing roller 4 on the front side of the conveying chain ladder 5 for the first time to suppress and crush the soil, and then conveying it backwards and upwards through the conveying chain ladder 5. A rake bar is arranged on the connecting rod of the conveying chain ladder 5, and the rake bar can further crush the soil blocks. The vibrating shaft 7 drives the vibrating wheel to rotate, and the vibrating wheel can drive the upper half of the chain of the conveying chain ladder 5 to shake up and down, thereby shaking off the broken soil blocks. When the peanuts are about to pass through the rightmost end of the conveying chain ladder 5, the roots of the peanuts still carry a certain amount of soil blocks. The peanuts and the soil blocks first fall to the front half of the floating roller 14, and then slide forward to the gap between the floating roller 14 and the fixed roller 13. The upper part of the fixed roller 13 rotates backward, and the upper part of the floating roller 14 rotates forward, driving the peanuts to move downward through the gap. When the size of the soil blocks on the peanuts is larger than the gap When the width is reached, the floating roller 14 overcomes the pulling force of the vibration shaft 7 of the tension spring 1, and rotates and floats upward with the hinge point of the front end of the rocker arm 15 and the frame 1 as the center, so that the soil blocks are crushed for the second time and the crushed soil falls to the ground. When the peanut vine passes through the gap, under the action of the vibration shaft 7 of the tension spring 1, the floating roller 14 rotates downward with the hinge point of the front end of the rocker arm 15 and the frame 1 as the center. During the working process of the secondary suppression and crushing device, the floating roller 14 floats up and down continuously to perform secondary soil crushing operations. After the secondary soil crushing, the peanut vines and fruits basically do not carry soil blocks and slide to the front side of the vine fruit laying and turning mechanism 6. The star disk of the vine fruit laying and turning mechanism 6 turns the peanut vines and fruits into a state with the fruit facing up and the vines facing down. The laying strips are laying grates, which guide the turned peanut vines and fruits, and cooperate with the star disk to lay the vines and fruits on the ground in the middle of the rear side of the frame 1. As the entire peanut harvester continues to move forward, the peanut harvesting operation is completed.

[0025] The utility model crushes soil by the soil crushing roller 4 once, crushes soil by the rake rod arranged on the connecting rod of the conveying chain ladder 5, and crushes soil by the floating roller 14 twice, so that the soil on the peanut seedlings is basically cleaned up, and the subsequent manual labor is fully reduced.

[0026] The spiral seedling-pulling blades 24 arranged on the outer circles of the left and right ends of the floating roller 14 rotate with the floating roller 14, and transport the peanut seedlings and fruits falling from the left and right ends of the conveyor chain ladder 5 to the middle, avoiding secondary crushing through the gap between the floating roller 14 and the fixed roller 13 and then falling vertically downward to the space between the left and right sides of the front part of the seedling-turning mechanism 6 for laying and turning the seedlings and fruits and the frame 1.

[0027] The rear side of the guide plate 25 can prevent the peanuts falling from the left and right ends of the conveyor chain ladder 5 from sliding backwards to the ground without secondary soil crushing. When the spiral seedling-pulling blades 24 pull the peanuts toward the middle during rotation, when they move to the bottom of the guide plate 25, the bottom of the guide plate 25 guides the peanuts toward the middle, preventing the peanuts from falling directly to the ground.

[0028] The soil crushing gap adjustment assembly 19 first loosens the locking nut 21, then turns the adjusting screw 22 to adjust the height of the upper end of the adjusting screw 22, and adjusts the height position of the rear end of the rocker arm 15, and the minimum gap between the soil crushing roller 4 and the fixed roller 13 is also adjusted accordingly. After the adjustment is completed, tighten the locking nut 21 to fix the adjusting screw 22. The rubber cap 23 at the upper end of the adjusting screw 22 reduces the impact force between the rocker arm 15 and the adjusting screw 22 when the floating roller 14 floats up and down, and plays a role in shock absorption and noise reduction.

[0029] The chain ladder 5 in the utility model is connected to the floating roller 14 and the fixed roller 13 by a chain transmission mechanism, which is a conventional technology, and the specific structure is not repeated.
