Weeding machine

Abstract

Weeding operation machine, the weeding head is connected with the chassis frame through the connection assembly; the connection assembly includes a welding frame, a lifting rod, a working head mounting plate and a hydraulic motor, two lifting rods are arranged side by side at the rear end of the welding frame, and the rear end of the lifting rod The joint bearing is hinged with the chassis frame, and the front end of the lifting rod is in the shape of a ball head, which is snapped into the welding frame, so that the welding frame can swing downward relative to the front end of the lifting rod, and the swing angle is less than 100°. The weeding operation head is installed There is a jacking hydraulic cylinder between the two working head mounting plates, between the welding frame and the front end of the chassis frame, and the two ends of the jacking hydraulic cylinder are respectively hinged on the front end of the chassis frame and the welding frame through joint bearings. The lifting hydraulic cylinder extends to lift up the welding frame, drives the lifting rod to swing upwards, and the weeding operation head is raised; the weeding operation machine of the present invention improves the fit between the weeding operation head and the grass surface, and performs meticulous treatment on the grass, improving the weeding efficiency. higher.

Description

technical field [0001] The invention relates to the field of weeding mechanical equipment, in particular to a weeding machine. Background technique [0002] The crawler weeder is a relatively common agricultural machine tool, which is used for high-speed weeding on relatively flat and large-area grasslands, and lays broken grass along the walking route while weeding, as arable land fertilizer. The front end of the crawler weeder is equipped with a weeding operation head, and the weeding knife in the weeding operation head rotates at high speed while the weeder is walking to mow the grass. Generally speaking, on the relatively flat grassland, there will be small undulating ground such as sloping, bulging and shallow pits, which cannot be completely flat. The weeding head at the front end of the weeding machine may have contact with the ground surface during the advancement process. Detachment or weeding knife will dig the surface soil layer, and the operator can change the w...

Problems solved by technology

Generally speaking, on the relatively flat grassland, there will be small undulating ground such as sloping, bulging and shallow pits, which cannot be completely flat. The weeding head at the front end of the weeding machine may have contact with the ground surface during the advancement process. Detachment or weeding knife to dig the surface soil layer, and the operator can change the working height of the weeding head to realize the fit between the weeding head and the ground surface, which is difficult to do on small undulating ground

Therefore, it may happen that the weeding operation head cannot always keep close to the surface during the operation. After the weeder passes by, the weeding may not be exhausted on the sloped and bulging ground, or the ground may be planed due to excessive weeding. Due to the situation, it is impossible to carry out detailed treatment on the grass
