Multiple-ridge peanut combine harvester

Abstract

The invention discloses a multiple-ridge peanut combine harvester. The multiple-ridge peanut combine harvester comprises a power device, a machine body, a harvesting table and a fruit collecting box, wherein the harvesting table and the fruit collecting box are installed on the machine body. The harvesting table and the fruit collecting box are installed on the front side and the back side of the machine body respectively, and a grain lifter and a soil shoveling device are connected to the front end of the harvesting table of the machine body; the harvesting table comprises a harvesting table frame, three or above slant peanut channels arranged upwards are arranged in the harvesting table frame side by side, chain-type elevating chains are arranged in all the peanut channels, and each chain-type elevating chain comprises two conveying chains engaged each other; a flapping soil shaking device is arranged in the middle of the harvesting table frame, a fruit picking assembly is connected to the lower side of the back portion of the hing table frame, and comprises a plurality of fruit picking rollers arranged side by side, and a slant vibrating screen arranged downwards is arranged below the fruit picking assembly. According to the multiple-ridge peanut combine harvester, a mechanical continuously-variable transmission is adopted, and is matched with static hydraulic driving, continuously-variable transmission is achieved, the variable speed mode is mellow, and the variable speed accuracy is high; meanwhile, the wheel type is matched, the walking speed can be increased, the fruit picking speed is in direct proportion to the walking speed of a vehicle accordingly, the fruit picking efficiency is improved, and the fruit completing rate is not influenced; the fruit completing rate mainly incarnates the completing degree of a fruit.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a peanut harvester. Background technique [0002] The backwardness of peanut harvesting methods in China at this stage has brought about various problems, which are generally manifested in the following three aspects: [0003] First, manual harvesting is labor-intensive and inefficient. For a long time, the harvesting of peanuts has been done manually, especially in recent years with the transfer of rural surplus labor, this contradiction has become more prominent. [0004] Second, the production cost is high. The current peanut harvesting is done by hand, animal power or simple machinery. The whole harvesting process is not completed at one time. It has to go through more than two processes. The main problem of the method is that there are many leakages of seedlings and fruits, and the missing seedlings and fruits are buried in the ground, which requires secondary recove...

Problems solved by technology

[0004] Second, the production cost is high

The current peanut harvesting is done by hand, animal power or simple machinery. The whole harvesting process is not completed at one time. It has to go through more than two processes. The main problem of the method is that there are many leaks of seedlings and fruits, and the lost seedlings and fruits are buried in the ground, which requires secondary recovery, which is not only labor-intensive, but also has high production costs.

[0005] Third, the delay in farming

[0008] 1. The peanut harvester of the prior art can only harvest a single ridge at a time

[0009] 2. At present, it is generally crawler-type walking, which is easy to compact the land after harvesting, which is not conducive to later sowing

[0011] 4. The traditional cab is open, and the driver is exposed to wind and sun for a long time

[0012] 5. After the traditional peanuts are harvested, they are collected manually in the field, or they are packed at the exit behind the machine, which is very laborious.

[0013] 6. Traditionally, belt-type mechanical transmission is used, which is prone to belt breakage, belt slippage, etc.

[0015] In addition, currently existing transmissions are generally matched with crawler type, and directly use the existing chassis structure and transmission structure without additional design. The fruit rate, limit the maximum travel speed of the crawler, but the efficiency of fruit picking will be reduced

In actual operation, when existing machines of the same type need to move backwards, the harvesting chain will reverse with the action of the wheels or crawlers, which will damage the seedling harvest, or the harvesting chain is faulty, and the chain must be reversed, and the wheels or crawlers must be reversed. Will destroy the topsoil of cultivated land
