Digging mechanism of potato harvester

Abstract

The invention discloses a harvester mechanism, and particularly relates to a digging mechanism of a potato harvester. The digging mechanism of the potato harvester comprises a digging shovel and a screening hopper; the two ends of a shovel head of the digging shovel are each connected with a transmission part through a transmission arm, wherein a positioning connecting piece used for fixation is arranged between each transmission arm and a clamp plate; each positioning connecting piece comprises a positioning sleeve and a positioning lock, wherein the positioning sleeve comprises a positioning head and a positioning cylinder which are integrated, transverse grooves are formed in the positioning head, an axial hole communicated with the transverse grooves is formed in the positioning cylinder, positioning notches are formed in the lower portion of the positioning cylinder, the positioning lock comprises two vertical supporting legs and a transverse rod, the transverse rod is inserted into one transverse groove, the lower ends of the vertical supporting legs are provided with bent parts fixedly clamped into the positioning notches, and the transmission arms and the clamp plates are clamped between the positioning heads and the bent parts. The technical defect that transmission arms in the prior art are prone to falling from transmission parts is overcome, and the digging mechanism of the potato harvester can prevent the transmission arms from falling from the transmission parts.

Description

technical field [0001] The invention relates to a harvester mechanism, in particular to a digging mechanism for a potato harvester. Background technique [0002] Potatoes are the main crop species in our country, especially in mountainous and hilly areas. Potatoes are both agricultural crops and economic crops, and are the main source of income for growers in the Midwest. However, with the expansion of the planting area, the harvest of potatoes has become a big problem. Manual harvesting requires a large amount of labor, high labor intensity, and long harvest time. Second, the labor cost continues to rise, which also seriously restricts the income of growers. Therefore, many machines for harvesting have occurred on the market, which mainly scatter the dug potatoes on the ground, and then need manual picking. But there are still some problems in the current potato harvesting machinery, especially the potato digging mechanism: [0003] 1. The structure is relatively complex...

AI Technical Summary

Problems solved by technology

[0003] 1. The structure is relatively complex and easy to damage potatoes;

[0004] 2. The separation rate of potatoes and soil is low, and the scattered area of ​​potatoes is large

[0007] Bolts are used to connect the transmission arm to the transmission part, but the bolts are easily affected by mechanical vibration and loosen the connection parts. If they are used for a long time, the transmission arm is easy to fall off from the transmission part.
