Embodiment 1

[0056] Such as figure 1 Shown, the ditching device in this ditching machine comprises ditching disc 1, connecting beam 3, connecting column 4 and driving assembly, and it is connected on the common tractor.

[0057] The connecting column 4 is prism-shaped, and the connecting column 4 is vertically fixedly connected on the vehicle body of the tractor. The inner end of the connecting beam 3 has a cylindrical connecting tube 5, the connecting tube 5 is set on the connecting column 4, the connecting tube 5 can translate along the connecting column 4, there is a positioning structure between the connecting tube 5 and the connecting column 4, through the positioning The structure enables the connecting cylinder 5 and the connecting column 4 to be positioned relative to each other.

[0058] Such as figure 1 and figure 2 and image 3 As shown, the ditching disc 1 is connected to the outer end of the connecting beam 3 , the inside of the connecting beam 3 is a cavity, the driving ...

Embodiment 2

[0078] The structure and principle of this embodiment are basically the same as that of Embodiment 1, except that the positioning structure includes two positioning notches 4b recessed on the connecting column 4 along its axial direction and a wrench 18 hinged on the connecting cylinder 5, The middle part of the wrench 18 is hinged on the connecting cylinder 5 and there is a spring 19 between the wrench 18 and the connecting cylinder 5. Under the elastic force of the spring 19, the inner end of the wrench 18 can be embedded in any of the above-mentioned positioning notches 4b, and the outer end of the wrench 18 Stretch out the outside of connecting cylinder 5, see Figure 7 shown.

[0079]In this embodiment, the side of the connecting cylinder 5 has a connecting hole 5 b through it, and the middle part of the wrench 18 is hinged at the connecting hole 5 b of the connecting cylinder 5 .

[0080] The operator applies external force to pull the wrench 18, and the applied externa...

Abstract

The invention provides a ditching device in a ditching machine, and belongs to the technical field of machines, which can be used for solving the problem that the existing ditching machine is low in applicability. The ditching device in the ditching machine comprises a ditching disc, a connecting beam, a connecting column and a driving assembly, wherein the connecting beam is in a prismatic shape and is used for being fixedly connected to a body of the ditching machine, a barrel-shaped connecting cylinder is arranged in the inner end of the connecting beam, the connecting cylinder sheaths the connecting column and can translate along the connecting cylinder, a locating structure which can locate the connecting cylinder and the connecting column is arranged between the connecting cylinder and the connecting column, the ditching disc is connected to the outer end of the connecting beam, the driving assembly is arranged at the connecting beam and is connected with the ditching disc, the ditching disc is in a discoid shape, and a plurality of projecting ditching bent blades are formed in the edge of the ditching disc. The ditching device in the ditching machine is high in adaptability and stability.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a ditching machine, in particular to a ditching device in the ditching machine. Background technique [0002] The trenching machine is used for trenching operations such as underground pipelines for farmland water conservancy irrigation, tap water pipelines and underground cable laying. [0003] The existing ditching machine is additionally provided with a ditching device on the basis of a common tractor, thereby carrying out the operation of ditch opening during the driving process of the tractor. [0004] Chinese Patent Publication No. CN2186981Y provides "an agricultural ultra-deep rotary tillage ditcher involving deep root crop cultivation", which is pulled and powered by a tractor, equipped with a power transmission system, a suspension system and a disc ditch opener. There is an auxiliary gearbox in the power transmission system, which is used to maintain and reduce the r...
