Description

Technical Field

[0001] This utility model relates to the field of peanut harvesting technology, and in particular to a peanut harvester. Background Technology

[0002] The peanut cleaning system is a mechanical system that uses wind power to separate peanuts from their vines. It is a type of fluid-powered machinery widely used in harvesting grains and other cereals.

[0003] like Figure 13 As shown in the diagram, the arrows represent the flow direction and trajectory of the material. In the domestic market, peanut cleaning systems mainly rely on a second cleaning fan 14 to deliver air, in conjunction with a third seedling collecting fan 15, to clean the peanuts on the sieve surface and at the tail end of the sieve 16. The third seedling collecting fan 15, besides assisting in cleaning, also collects a large amount of material from the seedling chopper 17 using suction and blows it into the seedling box. The third seedling collecting fan 15 serves both as an auxiliary cleaner and as a seedling conveyor. Because the seedling flow and the cleaning air path overlap during operation, they interfere with each other, making actual adjustment difficult. Furthermore, the third seedling collecting fan 15 experiences severe wear and tear and a reduced lifespan due to its direct contact with a large amount of material during operation. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a peanut harvester to address the shortcomings of the existing technology.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A peanut harvester includes: a frame, the frame being provided with a slitting unit and a cleaning unit, and further includes: a cleaning and conveying mechanism, the cleaning and conveying mechanism including a first conveying channel and a first seedling collecting fan provided in the first conveying channel, the inlet of the first conveying channel being connected to the cleaning unit; and a seedling conveying mechanism, the seedling conveying mechanism including a housing arranged in a left-right direction, the housing forming a second conveying channel, the housing being provided with an inlet connected to the slitting unit, and the housing being used to separate the first conveying channel and the second conveying channel.

[0006] The beneficial effects of adopting this utility model's technical solution are as follows: The shell separates the first conveying channel and the second conveying channel, preventing the main material from the drum from entering the cleaning system. This allows the first seedling collector blower's speed to be halved to meet the peanut cleaning needs. Eliminating the influence of material flow from the drum's discharge port and other factors on the cleaning system allows for individual adjustments to the cleaning system during peanut harvesting, making it more targeted. It reduces the amount of material passing through the first seedling collector blower, and under the same airflow conditions, the blower's speed can be reduced to half its original value, significantly improving its service life. The reduced airflow of the first seedling collector blower, coupled with the fact that speed adjustments only involve changes in the airflow, makes the adjustments more targeted and results in cleaner cleaning.

[0007] Furthermore, the housing is located on the lower inner side of the first conveying channel.

[0008] The beneficial effects of adopting the above-mentioned further technical solution are: it facilitates the separation of the first conveying channel and the second conveying channel through the shell, so that the main material from the drum does not enter the cleaning system, and the speed of the first seedling blower can be halved to meet the needs of peanut cleaning.

[0009] Furthermore, the housing is at least partially disposed between the left and right walls of the first conveying channel.

[0010] The beneficial effects of adopting the above-mentioned further technical solutions are: compact structure and reduced space occupancy.

[0011] Furthermore, the housing is provided with an arc-shaped shell with an axial feed inlet and a guide plate fixed between the feed inlet of the arc-shaped shell and the discharge port of the separating unit. The feed inlet of the arc-shaped shell is connected to the discharge port of the separating unit. The arc-shaped shell and the guide plate are used to separate the auger device from the cleaning unit and the first conveying channel.

[0012] The beneficial effects of adopting the above-mentioned further technical solution are: the arc-shaped shell and the guide plate separate the auger device from the cleaning unit and the first conveying channel. In the first conveying channel, the arc-shaped shell also serves as a guide for airflow, ensuring smooth air circulation.

[0013] Furthermore, the arc-shaped shell is provided with a plurality of reinforcing plates extending circumferentially, and the reinforcing plates are spaced apart along the axial direction.

[0014] The beneficial effect of adopting the above-mentioned further technical solution is to improve the load strength of the arc-shaped shell.

[0015] Furthermore, the arc-shaped shell is formed by three concentric arc-shaped plates that are sequentially fixed and connected.

[0016] The beneficial effects of adopting the above-mentioned further technical solutions are: it facilitates the installation and maintenance of the arc-shaped shell, and facilitates the installation and maintenance of the internal components of the arc-shaped shell.

[0017] Furthermore, the housing is equipped with an auger, and the discharge port of the housing is located at the outer end of the housing.

[0018] The beneficial effect of adopting the above-mentioned further technical solution is that a large amount of peanut vines from the drum are transported to the discharge port of the shell by the auger.

[0019] Furthermore, the housing is provided with an auger, a shredding device and a throwing mechanism arranged coaxially in sequence, and the discharge port of the throwing mechanism is the discharge port of the housing.

[0020] The beneficial effects of adopting the above-mentioned further technical solution are as follows: A large quantity of peanut vines from the drum is conveyed to the throwing mechanism via an auger device. During this process, a chopping device chops the vines, and finally, the throwing mechanism throws the vines through a second conveying channel to the vine storage device. By replacing the vine-collecting fan's function with the throwing mechanism, the overall durability of the machine is improved, and the failure rate of the vine-collecting mechanism is reduced. By exporting the material from the drum for throwing and collecting the vines, the first vine-collecting fan only participates in cleaning, reducing wear and extending its service life.

[0021] Furthermore, the housing is provided with an auger device and a shredder device arranged coaxially in sequence.

[0022] The beneficial effects of adopting the above-mentioned further technical solution are as follows: a large number of peanut vines from the drum are conveyed to the chopping device by the auger device, the chopping device chops the vines, and finally the peanut vines are thrown to the vine storage device by the second vine collecting fan set in the second conveying channel, or the vines are directly conveyed to the field to realize automatic return to the field.

[0023] Furthermore, both the first conveying channel and the second conveying channel are connected to a seedling storage device.

[0024] The beneficial effect of adopting the above-mentioned further technical solution is that it facilitates the collection of short straws, peanut leaves and other debris.
