Description

Technical Field

[0001] This invention relates to the field of peanut harvesting technology, specifically to a self-propelled peanut harvesting device. Background Technology

[0002] A peanut harvester is a crop harvesting machine used for harvesting peanuts. It can complete the peanut harvesting work efficiently and with low loss, bringing significant economic benefits.

[0003] The agricultural peanut harvester disclosed in CN113179739A includes a machine body, a harvesting mechanism for collecting peanuts and peanut vines from the field and transferring them into the machine body, a picking mechanism that can reciprocate vertically while continuously rotating relative to itself to filter and remove peanuts and attached materials from the roots of the peanut vines, and a separation mechanism that includes a screening mechanism and a cleaning mechanism.

[0004] When the above-mentioned peanut vine separating harvester is in use, the peanut vines harvested from the land are directly fed into the machine body through the harvesting mechanism and the peanuts and soil are peeled off onto the filter plate by the picking mechanism. However, the peanut vines that have just been pulled out have too much soil on them. If they are directly peeled off onto the filter plate, the filter plate will be easily blocked, which will affect the separation of soil and peanuts. Summary of the Invention

[0005] The purpose of this invention is to provide a self-propelled peanut harvesting device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A self-propelled peanut harvesting device includes:

[0008] The vehicle body has a support frame installed on it, and the support frame is inclined.

[0009] The collection component includes a seedling shoveling mechanism disposed at the end of the support, a seedling pulling mechanism and a seedling-fruit separation mechanism disposed on the support, and a soil removal mechanism disposed on the seedling pulling mechanism;

[0010] The collection component includes a collection box mounted on the vehicle body and a filtering mechanism disposed within the collection box. The vehicle body drives the stalk-pulling mechanism to move, causing a downward-moving shovel mechanism to insert into the soil and shovel up the peanut stalks. The stalk-pulling mechanism clamps the peanut stalks, pulls them up, and moves them along the stalk-pulling mechanism. The soil-removing mechanism causes the stalk-pulling mechanism to shake, causing the peanut stalks to shake off the soil from their roots. When the peanut stalks move to the stalk-separation mechanism, the stalk-separation mechanism separates the peanuts from the stalks, causing the peanuts to fall into the filtering mechanism, further separating the peanuts from the soil. The filtering mechanism then sends the peanuts into the collection box.

[0011] Preferably, the bracket includes a rice-shoveling telescopic rod mounted on the vehicle body and a mounting frame mounted on the rice-shoveling telescopic rod, the mounting frame being inclined.

[0012] Preferably, the seedling shoveling mechanism includes a loosening shovel mounted on the mounting frame and a gathering guide rod mounted on the side wall of the mounting frame, wherein the end of the gathering guide rod is horizontally positioned and spreads outward.

[0013] Preferably, the seedling pulling mechanism includes a rotating roller mounted on the mounting frame, a conveyor belt sleeved on the rotating roller, seedling pulling teeth mounted on the conveyor belt, a seedling pulling mounting plate mounted on the mounting frame, and a seedling pulling motor mounted on the seedling pulling mounting plate and connected to the rotating roller. The seedling pulling mechanism has two sets of corresponding seedling pulling teeth that mesh with each other.

[0014] Preferably, the shovel telescopic rod drives the mounting frame to move downward, so that the loosening shovel inserts into the ground when the vehicle moves, shoveling up the peanut vines. The retracting guide rod guides the peanut vines to the meshing point of the shovel-pulling teeth. The shovel-pulling motor drives the conveyor belt to rotate, so that the shovel-pulling teeth clamp the peanut vines, and the peanut vines move with the conveyor belt.

[0015] Preferably, the soil removal mechanism includes an inner moving rail disposed on the mounting frame and surrounded by the conveyor belt, an inner moving groove formed on the inner moving rail, a guide groove formed on the inner moving groove, a guide moving rod disposed in the guide groove, a guide moving ring and a guide moving wheel disposed on the guide moving rod, a support ring disposed in the guide groove and in contact with the guide moving ring, a limiting plate disposed on the guide moving rod, a limiting tube disposed on the limiting plate, a base disposed on the conveyor belt, and a support ring disposed on the inner moving rail. An outer moving rail, a swaying groove formed on the outer moving rail, an inclined slide rail set on the outer moving rail and at the swaying groove, an outer moving groove formed on the outer moving rail and the inclined slide rail, a swaying rod set on the base and passing through the outer moving groove and the limiting tube, a contact rod set on the swaying rod and extending one end of the limiting tube, a swaying block sleeved on the swaying rod, a swaying spring 1 set between the swaying block and the limiting tube, a swaying spring 2 set between the swaying block and the base, and an anti-wear wheel set on the swaying block.

[0016] Preferably, the conveyor belt drives the swaying rod to move, and the swaying block slides along the outer moving rail via the anti-wear wheel. When the swaying block moves to the swaying groove, the swaying block disengages from the outer moving rail, and the first and second swaying springs drive the swaying block to reciprocate along the swaying rod, impacting the contact rod and the base, thereby causing the conveyor belt to sway and shake off the soil on the peanut vines. When the swaying block moves to the inclined slide rail, it moves along the inclined slide rail and then moves back along the outer moving rail, allowing the first and second swaying springs to recharge.

[0017] Preferably, the seedling-fruit separation mechanism includes a fruit-dropping mounting plate mounted on the mounting frame, a fruit-dropping motor mounted on the fruit-dropping mounting plate, a fruit-dropping roller mounted on the fruit-dropping motor, and a fruit-dropping plate mounted on the fruit-dropping roller. The fruit-dropping plate rotates under the drive of the fruit-dropping motor to knock peanuts off the peanut seedlings.

[0018] Preferably, the collection box is equipped with a partition to divide the collection box into a peanut trough and a screening trough. The peanut trough is equipped with a feeding door, and the screening trough is equipped with a sewage discharge trough on its wall.

[0019] Preferably, the filtration mechanism includes a first screening telescopic rod and a second screening telescopic rod disposed in the screening trough, and a screening plate disposed on the first screening telescopic rod and the second screening telescopic rod and inclined thereon. The first screening telescopic rod and the second screening telescopic rod drive the screening plate to reciprocate and shake to further screen the peanuts.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] This invention, through the setting of a soil removal mechanism, allows the peanut vine pulling mechanism to shake off the soil when it moves to the shaking trough after pulling up the peanut vines, thereby reducing the amount of soil on the peanut vines and preventing excessive soil from clogging the filter plate. Through the setting of the filtration mechanism, the peanuts peeled off by the vine-fruit separation mechanism are further screened. Attached Figure Description
