Shearing device of garlic harvester

Abstract

The invention discloses a shearing device of a garlic harvester. The shearing device comprises a soil and garlic separation mechanism arranged on two symmetric side plates; the soil and garlic separation mechanism is provided with positioning mechanisms, stigma shearing mechanisms and stem shearing mechanisms; the soil and garlic separation mechanism comprises chain lifting units used for clampinggarlics to be conveyed; the soil and garlic separation mechanism is mounted on a tractor by the two symmetrically arranged side plates; the positioning mechanisms are used for carrying out positioning in a garlic lifting process; each stigma shearing mechanism comprises a guide frame and a blade arranged on the guide frame; and each stem shearing mechanism comprises two blades which are overlapped together, and the two overlapped blades are opposite in rotational direction. By utilizing a structure that one end of each chain lifting unit is fixed and the other end of the chain lifting unit issuspended, garlic clamping is more stable on one hand, and the change of the garlic size can be adapted by combination with the stigma shearing mechanisms on the other hand, so that the stigma shearing mechanisms can capture garlic stigmas more accurately.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a cutting device of a garlic harvester. Background technique [0002] When harvesting garlic, in order to ensure the integrity of garlic heads and garlic seedlings, it is necessary to carry out soil-breaking operations. The current garlic harvesting method is mainly to break the soil manually with a spatula and mechanical equipment. Manual soil breaking is used, and the labor intensity is relatively high; [0003] In addition, the harvesting of garlic is not a simple work of taking garlic out of the soil layer. It also involves a series of operations such as subsequent beard cutting and stem cutting, and finally obtains garlic heads. The existing basic principle is to use the clamping mechanism to The garlic stems are clamped and transported, and then transported to the collection place. It lacks the operation of cutting the beard and stems during the harvesting o...

[0003] In addition, the harvesting of garlic is not a simple work of taking garlic out of the soil layer. It also involves a series of operations such as subsequent beard cutting and stem cutting, and finally obtains garlic heads. The existing basic principle is to use the clamping mechanism to The garlic stems are clamped and transported, and then transported to the collection place. It lacks the operation of cutting the beard and stems during the garlic harvesting process. In addition, due to the special situation of garlic, that is, it has a larger garlic head, which is in the clamping process. During the process of holding and transporting, the requirements for the holding mechanism are relatively high. If the holding is not stable enough, the probability of dropping garlic will be very high, resulting in waste.
