Soil divider of ditching machine

Abstract

An earth divider for the ditch digger which is installed to front end of a walking tractor is arranged above the cutting wheel of ditch digger, and has V-shaped earth dividing plate and supporting rod whose top end is connected to said earth dividing plate via hinge-locking mechanism on which a regulator is set up.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and relates to a soil divider for a trencher. Background technique [0002] The top of the cutter head of the existing front-mounted trencher is generally provided with a soil divider, including a soil divider and a support column. The specific structure is a V-shaped soil divider, with two or four support columns and the ditcher machine frame fixing (if the frame is provided with a structure for directly fixing the soil dividing plate, it can also be considered that the structure is a special case of "support column", and the soil dividing plate mentioned in this special case is also referred to in the present invention Soil divider), its main function is sufficient: when the soil milled by the cutter head is projected upwards and collides with it, it will be refracted and distributed to both sides of the ditch, and at the same time prevent the soil clods from being thrown backwards to the o...

AI Technical Summary

Problems solved by technology

Since the distance between the cutter head and the soil divider will affect the throwing distance of the thrown soil clods, the traditional concept is that: the lower edge line of the soil divider in the soil divider must be concentric or approximately concentric with the outer ring of the cutter head. arc, otherwise the purpose of uniform soil distribution cannot be achieved

Therefore, the lower edge lines of the soil divider plates of all soil dividers are designed to be arc-shaped; and because of the arc-shaped design of the lower edge line, two plates are generally used to connect them during manufacture, and it is not easy to use a whole plate

The structure of the connection of two plates, or the arc-shaped structure of the lower edge line respectively cause the following disadvantages: 1. The uniformity of throwing soil and the distance of coverage cannot meet the agronomic requirements

The soil quality of the farmland is very complex, and the moisture content varies greatly even between adjacent fields due to the difference in height. Therefore, the non-adjustable fixed elevation angle, height and the same V-shaped angle of the prior art soil divider cannot adapt to different soil properties. and agronomic requirements

5. Security is not good enough

During the operation of the trencher, the lower part of the cutterhead rotates forward and the upper part backwards (in the direction shown by the arrow in the figure) at high speed, and the soil is milled into pieces by the blade, which moves with the blade under the action of friction and inertia of the blade. It is projected outwards under the action, in which most of the soil clods in front of the vertical line of the center of the cutter head are forward and upward, and only a small amount of soil clods behind the vertical line of the center of the cutter head are backward. Although the proportion is small, from the perspective of safety, even It is not allowed to throw a piece of soil at the operator
