Abstract

The invention discloses a chain type ditching machine, which comprises a gearbox. The casing of the gearbox is rotatably connected with a support frame. The end of the support frame close to the gearbox is rotated with a drive wheel, and the end of the support frame far away from the gearbox is rotated with a drive wheel. The driven wheel and the driving wheel are connected to the driven wheel through the transmission chain, the two adjacent links of the transmission chain are fixed with trenching knives, the middle part of the support frame is fixed with a sleeve, and the inner hole of the sleeve is slidingly connected with an adjustable Rod, the end of the adjustment rod away from the sleeve rotates with a roller, which is in contact with the transmission chain; a spring is also arranged in the sleeve, one end of the spring is in contact with the adjustment rod, and the other end of the spring is fixed. The chain trencher of the present invention can automatically adjust the tightness of the transmission chain when digging trenches, thereby improving the working efficiency of the chain trencher and prolonging the service life of the chain trencher.

Description

technical field [0001] The invention relates to the technical field of trenching and grooving devices, in particular to a chain trencher. Background technique [0002] Trench digging machine is a device for digging trenches, which can be used in construction projects to dig narrow and deep underground trenches to bury underground drainage pipes, or to bury cables and pipes in railways, post and telecommunications, urban construction and other departments. It can also be used in orchards, vegetable gardens and other farmland environments for digging fertilization, drainage and irrigation. [0003] At present, most of the trenchers on the market are chain trenchers. A trencher knife is installed on the chain link of the transmission chain of the chain trencher, and the power system drives the transmission chain to run to dig trenches. This chain trencher has high trenching efficiency, simple structure and reliable use, but it is difficult to control the tightness of the trans...
