Peanut harvester and weed-throwing and dust-settling mechanism thereof

Abstract

The invention discloses a peanut harvester and a weed-throwing and dust-settling mechanism thereof. The peanut harvester comprises a picking platform, a bridge, a peanut picking mechanism, a choppingmechanism and a weed-throwing and dust-settling mechanism which are sequentially arranged from front to back along the direction of a vehicle body; a cleaning mechanism is arranged below the peanut picking mechanism; peanuts with stems are collected by the picking platform and then are conveyed to the peanut picking mechanism through the bridge; coarse stalks flow to the chopping mechanism to be chopped to form stalk residues; the weed-throwing and dust-settling mechanism comprises a weed-throwing fan and a weed box assembly provided with an air outlet; the weed-throwing fan is arranged at theintersection of the cleaning mechanism, the chopping mechanism and the weed box assembly, so that fine stalks of the cleaning mechanism sequentially pass through the inlet of the weed-throwing fan, afan impeller of the weed-throwing fan and the outlet of the weed-throwing fan to be thrown towards the weed box assembly, and stalk slag flows towards the outlet of the weed-throwing fan to be throwntowards the weed box assembly. The energy consumption of the weed-throwing fan is reduced, and the low-power weed-throwing fan is lower in manufacturing cost and easy to realize; and the air outlet speed is small, the dust amount is reduced, and the pollution of raised dust to a human body and the environment is relieved.

Description

technical field [0001] The invention relates to the technical field of peanut harvesting, in particular to a peanut harvester and a grass-throwing and dust-reducing mechanism thereof. Background technique [0002] With the continuous improvement of production economy, agricultural mechanization is the development trend of modern agriculture. Peanut is a common economic crop, but the harvesting steps are complicated and the labor cost is high, so the peanut picking and harvesting machine came into being. [0003] At present, during the harvesting operation of the peanut picking and harvesting machine, the stalk residue after being chopped by the chopping mechanism and the thin stalks falling together with the peanuts must pass through the inlet of the weed blower and the fan impeller of the weed blower in turn. And the outlet of the grass-throwing fan is thrown to the grass box, the gas contains a large amount of impurities, and the impeller of the fan is worn, which reduces...

Peanut is a common economic crop, but the harvesting steps are complicated and the labor cost is high, so the peanut picking and harvesting machine came into being

[0003] At present, during the harvesting operation of the peanut picking and harvesting machine, the stalk residue after being chopped by the chopping mechanism and the thin stalks falling together with the peanuts must pass through the inlet of the weed blower and the fan impeller of the weed blower in turn. And the outlet of the grass-throwing fan is thrown to the grass box, the gas contains a large amount of impurities, and the impeller of the fan is worn, which reduces the service life of the grass-throwing fan and increases the maintenance cost of the peanut picking and harvesting machine; And because all the debris needs to be lifted by the fan impeller, the exhaust air volume of the weed blower needs to be large to ensure that the waste is collected in the grass box. The outlet wind speed of the weed blower of the existing peanut picking harvester is generally 42-45m / s, resulting in high energy consumption of the grass throwing fan, wasting energy; due to the high wind speed of the outlet of the grass throwing fan, a large amount of dust is discharged from the air outlet of the grass box, and the direction of the air outlet of the general peanut harvester is upward or To both sides, due to the large air volume and dust, it pollutes the environment and produces a lot of dust, which is not conducive to human health and environmental protection.
