Problems solved by technology

Due to this structure, the soil-turning device is arranged inside the frame of the fixed frame, and the two hydraulic cylinders are respectively arranged on the front and rear sides of the fixed frame, which makes it difficult to disassemble and install the soil-turning device and its accessories, and it is difficult to replace and maintain it. It also increases the structural complexity and manufacturing cost to a certain extent

Embodiment approach

[0021] As the first embodiment of the cantilever vertical lifting system of the present invention, the frame 2 is provided with an upper plate-shaped structure 22 and a lower plate-shaped structure 21, and two guide rods 3 pass through the guide part 61 and the guide sleeve. 6 sliding connection, one end is fixedly connected with the lower plate structure 21, and the other end is fixedly connected with the upper plate structure 22. The guide rod 3 includes a bolt head 31, a threaded portion 33, and a nut 32. The guide rod passes through the through hole provided on the upper plate structure 22, the guide hole portion 61 of the guide sleeve 6, and the lower plate structure 21. The through hole, and then the nut 32 is screwed on the threaded part 33 to realize the fast connection between the guide rod 3 and the frame 2. There are two guide sleeves, and each guide sleeve 6 is provided with a connecting portion 62 and a guide hole portion 61 matched with the guide rod, and one end...

Abstract

The invention discloses a cantilever vertical lifting system. The cantilever vertical lifting system comprises a rack, a guide sleeve, a hydraulic cylinder and a working component. The working component comprises a spiral bit and a transmission case. The rack is provided with a plurality of vertical guide rods located on the same plane. The guide sleeve comprises a connecting part, a guide hole part and a connecting base. The guide hole part is provided with guide holes matched with the guide rods. The guide rods penetrate through the guide holes of the guide sleeve and are connected with the guide sleeve. The guide sleeve is fixedly connected with the transmission case of the working component. One end of the hydraulic cylinder is hinged to a hinging base at the lower portion of the rack through a hinge, and the other end of the hydraulic cylinder is fixedly connected with the connecting base of the guide sleeve through a connecting structure. According to the cantilever vertical lifting system, disassembly convenience, assembly convenience and maintenance convenience are achieved, and structure miniaturization is achieved as well. In addition, the cantilever vertical lifting system is simple in structure and high in stability and has good structural stability and operational safety.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a cantilever vertical lifting system suspended by a tractor. Background technique [0002] In the Chinese utility model patent whose authorized announcement number is CN201878501U, a kind of greenhouse deep-turning machine is disclosed, which includes a traveling device and a soil-turning device arranged at its rear end. The movable frame on the fixed frame, the lifting device controlling the up and down movement of the movable frame, the transmission device and the tensioning device are composed. The upper end is open, and the movable frame is provided with a sleeve slidingly connected with the column. The drill rod driving mechanism body of the movable frame includes a horizontal transmission shaft and a vertical drill rod shaft meshed with bevel gears, and the drill rod shafts are arranged in pairs. At the lower part of the transverse drive shaft, a drill pipe is connect...
