Abstract

The utility model relates to a ditching disc with adjustable ditching width, which is composed of vertical ditching knives, a knife sleeve, a disc, horizontal ditching knives, connecting rods, bolts, nuts and a disc drive shaft. The longitudinal ditching blade is axially installed on the cutter holder, the cutter holder is threadedly connected with the disc through the bolt at one end, and the cutter holder is welded with the bolt through the connecting rod, and the bolt is fixed in the arc groove by the nut. When working, the drive shaft of the disk drives the disk to rotate in the opposite direction to open the ditch, the tool holder is reversely stressed, the nut at one end of the cutter holder is locked, and the cutter holder shares part of the force through the connecting rod. Replace the vertical blade to adjust the width of the ditch, adjust the cutting angle of the blade to change the stress situation. The installation of the longitudinal ditching knife increases the width of the disc type ditching of the walking tractor, conforms to reality, has a simple structure, brings convenience to agriculture, and is suitable for market demand.

Description

A ditching disc with adjustable ditching width

technical field

The utility model designs a ditching device for a walking tractor, in particular to a ditching disc whose ditching width can be adjusted by replacing a vertical ditching blade.

Background technique

At present, the hand-held disc trencher drives the disc drive shaft through gear or chain transmission, and the disc drive shaft drives the two discs to rotate. During the ditching process, the soil between the two discs depends on the scraper behind Scrape the soil to both sides, the distance between the two discs should not be too large, so the ditching width of the walk-behind disc ditching machine is limited, and there is a great technical requirement for the ditching width, an urgent need for a ditching The ditching disc with adjustable width can solve the problem of ditching width.

Utility model content

In order to solve the above problems, the utility model provides a ditching disc with adjustable ditching width. The disc increases the width of the disc-type ditching of the walking tractor, conforms to reality, has a simple structure, brings convenience to agriculture, and is suitable for market demand.

In order to achieve the above purpose, the utility model adopts the following technical solutions: a ditching disc with adjustable ditching width, which is characterized in that: a vertical ditching knife, a knife sleeve, a disc, a horizontal ditching knife, a connecting Composed of rods, bolts, nuts, and disc drive shafts, the longitudinal ditching blade is axially installed on the tool holder, the tool holder is threaded with the disc through a bolt at one end, the tool holder is welded to the bolt through the connecting rod, and the bolt passes through The nut is fixed in the arc groove.

In the above technical solution, when working, the drive shaft of the disk drives the disk to reversely rotate to open the ditch, the cutter holder is under reverse force, the nut at one end of the cutter holder is locked, and the cutter holder shares part of the force through the connecting rod. When not working, replace the vertical blade to adjust the width of the ditch, adjust the cutting angle of the blade to change the stress situation.

detailed description

Below in conjunction with accompanying drawing, the utility model is described further:

In the figure, it is mainly driven by vertical ditching knife (1), knife holder (2), disc (6), horizontal ditching knife (4), connecting rod (8), nut (5) and disc. Shaft (7) composition. The longitudinal ditching cutter (1) is axially installed on the cutter holder (2), and the cutter holder (2) is fixed with the disc nut (5) by the bolt at one end, and the cutter holder (2) is fixed by the connecting rod (8 ) are welded together with the bolt, and the bolt is fixed in the arc groove (3) by the nut (8). When working, the disk drive shaft (7) drives the disk to reversely rotate to open the ditch, the knife sleeve (2) is reversely stressed, the nut (5) at one end of the knife sleeve is locked, and the knife sleeve (2) shares a part of it through the connecting rod (8) force. When not working, replace the vertical ditching knife (1) to adjust the ditching width, and adjust the cutting angle of the blade to change the stress situation. The utility model conforms to reality, has a simple structure, brings convenience to agriculture, and is suitable for market demand.

This embodiment is only an illustration of the concept and realization of the utility model, and does not limit it. Under the concept of the utility model, technical solutions without substantial transformation are still within the scope of protection.
