Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a self-propelled peanut picking and harvesting device. Background Technology

[0002] With the development of science and technology, people's lives have gradually improved, and various tools have emerged rapidly in daily life. Especially in agriculture, in the past, peanut harvesting was done manually in the fields. Gradually, peanut harvesting devices were successfully developed, which liberated farmers from heavy physical labor, made people's lives more convenient, and eliminated the need for manual labor to harvest peanuts.

[0003] During peanut harvesting, peanut excavators are first used to dig the peanuts out of the soil. The peanuts are then exposed to the ground and allowed to dry naturally for about five days to reduce moisture. Afterward, a peanut picking and harvesting device is used to pick up, pluck, sieve, and collect the dried peanuts. During the picking process, picking rollers collect the peanuts from the ground and convey them into the machine for further processing. However, due to uneven ground levels, the picking rollers cannot effectively contact the ground, resulting in some peanuts not being picked up. Additionally, when the peanuts are too scattered, the picking rollers' gripping ability decreases, causing some peanuts to be missed. Utility Model Content

[0004] To address the issues in the background technology where uneven land heights prevent the picking roller from effectively contacting the ground, resulting in some peanuts not being picked up and the picking roller's reduced gripping ability when peanuts are too scattered, leading to some peanuts being missed, this utility model proposes a self-propelled peanut picking and harvesting device.

[0005] The technical solution of this utility model is: a self-propelled peanut picking and harvesting device, including a picking platform, a picking roller extending in the left and right direction is rotatably provided inside the picking platform, a plurality of toothed rings are fixedly sleeved on the picking roller and spaced apart along its extension direction, a conveying roller is rotatably provided inside the picking platform, two auger conveyor belts are fixedly provided on the conveying roller, the two auger conveyor belts are symmetrically arranged, and a material conveying pipe is fixedly connected and communicated to the rear end of the picking platform, and a conveyor belt is provided inside the material conveying pipe;

[0006] The front bottom of the picking platform is fixed with multiple guide rods that extend forward and are spaced apart in the left and right direction. The picking roller is located above the rear end of the guide rods. The front end of the guide rods is inclined from top to bottom and from back to front, so as to guide the peanuts that are close to the ground to the bottom of the picking roller during the movement.

[0007] Preferably, the front of the guide rod is fixed with an arrow, which is a flat triangular pyramidal structure that gradually increases in cross-section from front to back.

[0008] Preferably, a rotating shaft is rotatably provided at the bottom front end of the pickup platform, and the rear ends of multiple guide rods are fixedly mounted on the rotating shaft. Both ends of the rotating shaft rotatably extend out of the pickup platform and are fixedly provided with a lever that is inclined from bottom to top and from front to back. Fixed columns are fixed on both sides of the pickup platform. A tension spring is provided between the lever and the fixed column on the same side. The tension spring can apply a downward force to the multiple guide rods through the lever and the rotating shaft so that the front end of the guide rod can always be in contact with the ground.

[0009] Preferably, a limiting rod is fixedly provided at the bottom front end of the pickup platform, and the limiting rod is located below the middle of the guide rod.

[0010] Preferably, the pickup roller is fixed with multiple sets of gripping rods spaced apart from left to right. Each set includes multiple gripping rods evenly distributed along the circumferential direction of the pickup roller. The gripping rods are offset from the toothed ring to the left and right, and the gripping rods are offset from the guide rods to the left and right.

[0011] Preferably, a rotating rod is rotatably provided inside the picking table. The rotating rod is located above the picking roller. Two ring plates are fixedly sleeved on the rotating rod and spaced apart from each other. Multiple material-pulling rods are fixedly arranged circumferentially between the two ring plates.

[0012] Advantages of this invention: This invention features multiple guide rods arranged at an angle from top to bottom and from back to front at the front of the picking platform. When the front ends of these guide rods are in contact with the ground, they guide peanuts at lower positions upwards, preventing peanuts located below the picking roller from being ineffectively picked up. This effectively solves the problems of uneven ground height and the picking roller not being able to stay close to the ground. At the same time, the multiple guide rods spaced apart on the left and right sides can guide scattered peanuts to the area below the picking roller, helping to guide the scattered peanuts into the picking roller and improving picking efficiency.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: A self-propelled peanut picking and harvesting device, such as Figure 1-3 As shown, the system includes a picking platform 1, which is a bucket-shaped structure with an opening at the front and top. A picking roller 2 extending in the left-right direction is rotatably mounted inside the picking platform 1. Multiple toothed rings 3, spaced apart along their extension direction, are fixedly fitted onto the picking roller 2. The picking roller 2 uses the toothed rings 3 to grab peanuts from the ground and transports them by rotation. A conveyor roller 4 is rotatably mounted inside the picking platform 1, and two auger conveyor belts 5 are fixedly mounted on the conveyor roller 4. The two auger conveyor belts 5 are symmetrically arranged. By driving the two symmetrically arranged auger conveyor belts 5, the conveyor roller 4 can concentrate the peanuts in the middle of the picking platform 1. A conveyor pipe 6 is fixedly connected to and communicates with the rear end of the picking platform 1. A conveyor belt is installed inside the conveyor pipe 6. The conveyor belt is used to transport the peanuts concentrated in the middle of the picking platform 1 to the rear for further processing. For those skilled in the art, the conveyor belt is a well-known technology and is not shown in the figure, so it will not be described in detail.

[0020] Multiple guide rods 7 extending forward and spaced apart in the left-right direction are fixedly provided at the bottom front end of the picking platform 1. The picking roller 2 is located above the rear end of the guide rods 7. The front ends of the guide rods 7 are inclined from top to bottom and from back to front. The front ends of the guide rods 7 are close to the ground, which can guide the peanut material at a lower position to move upward, avoiding the peanuts located below the picking roller 2 from not being effectively picked up. This effectively solves the problem of uneven ground height and the picking roller not being able to stick to the ground. At the same time, the multiple guide rods 7 spaced apart in the left and right directions can guide the scattered peanuts to the bottom of the picking roller 2, helping to guide the scattered peanuts into the picking roller and improving the picking efficiency. An arrow 8 is fixedly provided at the front of the guide rod 7. The arrow 8 is a flat triangular pyramid structure with a cross-section that gradually increases from front to back. The arrow 8 at the front end of the guide rod 7 can be inserted into the soil to reduce the resistance at the end of the guide rod 7, prevent the guide rod 7 from deforming, and thus improve the stability of the guide rod.

[0021] To ensure that the front end of the guide rod 7 remains in contact with the ground when traversing uneven terrain, a rotating shaft 9 is rotatably mounted at the bottom front of the pickup platform 1. The rear ends of multiple guide rods 7 are fixedly mounted on the rotating shaft 9. Both ends of the rotating shaft 9 rotatably extend out of the pickup platform 1 and are fixedly mounted with a lever 10 that is inclined from bottom to top and from front to back. Fixed posts 11 are fixed on both sides of the pickup platform 1. A tension spring 12 is provided between the lever 10 and the fixed post 11 on the same side. The tension spring 12 can apply a downward force to the multiple guide rods 7 through the lever 10 and the rotating shaft 9, so that the front end of the guide rod 7 can always remain in contact with the ground.

[0022] To prevent the guide rod 7 from tilting too much at the ground and affecting its normal use, a limiting rod 13 is fixedly installed at the bottom front end of the pickup platform 1. The limiting rod 13 is located below the middle of the guide rod 7. Under normal conditions, the tension spring 12 can apply a downward force to multiple guide rods 7 through the actuating rod 10 and the rotating shaft 9, so that the guide rod 7 presses against the limiting rod 13.

[0023] Multiple sets of gripping rods 14 are fixedly arranged on the picking roller 2 at left and right intervals. Each set includes multiple gripping rods 14 evenly distributed along the circumference of the picking roller 2. The gripping rods 14 are staggered with the toothed ring 3 and staggered with the guide rod 7. The gripping rods 14 can further improve the picking roller 2's ability to grip peanuts.

[0024] Inside the picking platform 1, there is a rotating rod 15, which is located above the picking roller 2. Two ring plates 16 are fixedly sleeved on the rotating rod 15, which are spaced apart from each other. Between the two ring plates 16, there are multiple material-pulling rods 17 that are spaced apart along their circumference. The material-pulling rods 17 can guide the peanuts located above the picking roller 2 to be conveyed, helping the material to smoothly enter the auger conveyor belt 5 and avoid accumulation or blockage.

[0025] Working principle: When picking up peanuts, the picking platform 1 is lowered to a certain height so that the arrow 8 at the front end of the guide rod 7 is close to the ground. Then, the picking platform 1 is driven to move. The peanuts are guided by the guide rod 7 to move upward to the bottom of the picking roller 2. During the rotation of the picking roller 2, the peanuts are flipped and conveyed to the conveying roller 4 by the toothed ring 3 and the gripping rod 14. The conveying roller 4 concentrates the peanuts at the front end of the conveying pipe 6 by the auger conveyor belt 5 and then conveys them to the rear for further processing.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
