Four-blade type vegetable supporting device acting on vegetable leaves and stems

Abstract

The invention relates to a four-blade type vegetable supporting device acting on vegetable leaves and stems. A vegetable supporting main transmission shaft is perpendicular to the advancing directionof a harvester, three vegetable supporting secondary transmission shafts are arranged, the connection lines between the vegetable supporting main transmission shaft and the circle centers of the threevegetable supporting secondary transmission shafts form an inverted trapezoid, an included angle is formed between the lower bottom edge of the inverted trapezoid and a horizontal plane, and two parallel vegetable supporting transmission chains are arranged on the vegetable supporting main transmission shaft and the vegetable supporting secondary transmission shafts through transmission chain wheels and mounted on the two sides of a bracket. The vegetable supporting transmission chains are provided with rotating pipe brackets, a rotating pipe is arranged on each rotating pipe bracket, a four-blade type vegetable supporting combination is vertically connected to each rotating pipe, each sliding block is in rigid connection with the two ends of the corresponding rotating pipe, and a slidinggroove is formed below each rotating pipe bracket. When the device is used for supporting vegetables, the sliding blocks slide into the sliding grooves, the sharp edge of each four-blade type vegetable-supporting combination faces the roots of the vegetables. The device can support the vegetables in different directions and carry out orderly conveying.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to leafy vegetable harvesting machinery, and in particular to a four-blade vegetable-supporting device acting on vegetable leaves and stems. Background technique [0002] At present, some of the leafy vegetable harvesters reported in the field of domestic vegetable harvesting machinery use transmission chains for transportation, which causes vegetables to be easily broken by the vegetable support pole during transportation, and it is not easy to maintain the integrity of vegetables; some use flexible conveying devices. Vegetable support and transportation, such as the application number: 201821806852.X (a flexible vegetable picking device acting on vegetable leaves and stems), its defect is that it cannot hold vegetables in a direction parallel to the machine’s walking direction, and cannot fully hold them. If the vegetables are not held, there will be a phenomenon of missing d...
