Problems solved by technology

If this kind of peanut harvester cannot harvest the peanuts before they are mature, the mature peanuts will fall, and the peanuts that fall into the soil cannot be collected
In addition, under the current environment where the burning of straw is prohibited, the peanut harvesters on the market can only harvest peanuts, and the peanut stalks that have been removed from the peanuts are only stacked in the field, which is inconvenient to clean and degrades slowly.

Embodiment 1

[0053] Such as Figure 1-2 As shown, a peanut harvesting device provided by the present invention includes a frame 1, and also includes an excavating assembly 2, a conveying mechanism 3, a separating assembly 4, a screening mechanism 5, and a peanut collecting mechanism arranged on the frame 1. 6 and power components; the digging assembly 2 is used to dig up peanut plants and soil together; the digging assembly 2 is connected to the input end of the screening mechanism 5; the separation assembly 4 is located on the upper side of the screening mechanism 5 , the separation assembly 4 is used to separate the peanut from the root of the peanut plant; the screening mechanism 5 at least includes a soil screening part 51 distributed along the conveying direction and a peanut and branch screening part 53; the conveying surface of the conveying mechanism 3 Set close to the top of the screening surface of the screening mechanism 5, the conveying mechanism 3 transports the peanuts separa...

Embodiment 2

[0055] Take the forward direction of the peanut harvesting device as the front, and the direction away from the forward direction as the rear.

[0056] Such as Figure 3-5 As shown, on the basis of Embodiment 1, the digging assembly 2 is located at the front of the peanut harvesting device, and the conveying mechanism 3 is located at the top of the screening section. The peanut digging assembly 2 includes a digging shovel 21, a pressing roller 22 located at the front of the contact point between the digging shovel 21 and the ground, and the pressing roller 22 is connected to the frame 1 through a support rod; the two ends of the support rod They are respectively connected to the rotating shaft of the pressure roller drum 22 and the frame 1 in rotation; between the support rod and the first fixed rod fixed on the frame 1, there is an elastic part for adjusting the roller that can be used to adjust the depth of the digging shovel 21 into the soil. The screening mechanism 5 incl...

Embodiment 3

[0060] Such as Figure 6 , 7As shown, on the basis of Example 2, the fruit-picking mechanism 42 includes a first fruit-picking cylinder 421 and a second fruit-picking cylinder 422; The curved tooth 42122 is bent towards the elastic part 42121 on one side; one end of the curved tooth 42122 is connected to the drum body 4211 in rotation, and the other end is bent in the opposite direction of the rotation of the drum body 4211; one end of the elastic part 42121 is fixed to the curved tooth 42122 The other end is fixedly connected to the roller body 4211; the roller body 4211 is also provided with a barrier 4214 for preventing the curved tooth 42122 from rotating to the side away from the elastic part 42121;

[0061] The curved tooth portion 4212 of the second fruit picking cylinder 422 has the same structure as the curved tooth portion 4212 of the first fruit picking cylinder 421; or, the curved tooth portion 4212 of the second fruit picking cylinder 422 is only a curved tooth p...

Abstract

The invention discloses a peanut harvesting device and relates to the technical field of agricultural machinery. The peanut harvesting device comprises a rack, a digging component, a conveying mechanism, a separation component, a screening mechanism, a peanut collection mechanism and a power component, wherein the digging component is used for digging up peanut plants and soil together; the digging component is connected with the input end of the screening mechanism; the separation component is arranged on the upper side of the screening mechanism; the separation component is used for separating peanuts from roots of the peanut plants; the screening mechanism at least comprises a soil screening part and a peanut and stem screening part which are distributed in a conveying direction; the conveying surface of the conveying mechanism is arranged close to the top of the screening surface of the screening mechanism; peanuts separated from the peanut and stem screening part are conveyed to the peanut collection mechanism by the conveying mechanism; the power component is used for providing power. The harvesting device disclosed by the invention is high in harvesting rate, high in integration rate and free of excessive operation of operators; a stem crushing device is additionally arranged behind the harvesting device, then stems can be crushed, labor can be saved, and diseases and insects can be reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a peanut harvesting device. Background technique [0002] Peanut is the main economic crop in my country. The annual planting area of ​​our country reaches more than 60 million mu, and the total output is more than 11 million tons. It is one of the countries with the largest peanut production in the world. For a long time, the planting, harvesting and processing of peanuts have been done manually, and it takes one-third of the entire production process to harvest. Most of the existing peanut harvesters first loosen the soil, hold the peanut rod after loosening the soil, guide the chain to clamp, and move to the fruit picker backwards, along with shaking, remove the soil, and pick the peanuts at the fruit picker. The picking rate of its peanuts is low, accompanied by a lot of fruit drop. If this type of peanut harvester cannot harvest the peanuts before they matur...
