Abstract

The invention relates to a horizontal lifting device of a furrow opener of a walking-type sowing machine, and belongs to walking-type sowing machines for agricultural machinery. According to the horizontal lifting device, a parallel four-connecting-rod device, a lifting device, a hydraulic device and a seed discharging transmission device are all installed on a rack assembly; a lifting square frame of the parallel four-connecting-rod device is connected with a lifting rod of the lifting device through lifting clamping lugs; a driving lifting arm of the lifting device is connected with an oil cylinder of the hydraulic device through a driving lifting arm pin shaft; an oil pump of the hydraulic device is connected with a walking-type tractor clutch wheel through a walking wheel; a seed discharging device of the seed discharging transmission device is installed on the lifting square frame; the rack assembly is connected between a hanging frame of a walking-type tractor and a tail wheel; the furrow opener is located at the lower portion of the middle of the rack assembly and installed on the lifting square frame of the parallel four-connecting-rod device. The horizontal lifting devicehas the advantages that by utilizing power of the walking-type tractor, the furrow opener always rises or falls stably and reliably in the horizontal direction; the device is high in automation degreeand stable and reliable in working performance, and the depth adjustment and lifting of the furrow opener are convenient and quick.

Description

technical field [0001] The invention relates to a walk-behind seeder, belonging to agricultural machinery, in particular to a horizontal lifting device of a trench opener of the walk-behind seeder. Background technique [0002] At present, the connection method of the opener of the planter matched with the walking tractor is that the opener is rigidly connected to the planting frame and is hinged with the adjustment rod. During the operation of the opener, the opener is adjusted relative to the planter by adjusting the rod. The height of the frame or the ground wheel can adjust the depth of the trench and the lifting function. The current structure cannot solve the problem of changing the ditching height of the opener relative to the seeding rack or the ground wheel, and the inconsistency of the sowing depth of the opened ditch, which affects the high and stable yield of crops. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a horizont...
