Protection structure for agricultural ditcher chains

Abstract

The invention provides a protection structure for agricultural ditcher chains. The protection structure comprises the chains; a main bearing penetrates through the interior of the each chain, an innerbearing penetrates through the interior of the main bearing, buffer columns are distributed on the outer side of the inner bearing, limiting frames are distributed on one sides of the buffer columns,buffer frames are distributed on the other side of the inner bearing, fixing blocks are arranged on the two sides of the limiting frames, connecting frames are arranged on one sides of the limiting frames, clamping blocks are embedded in the inner side of each connecting frame, and a clamping groove is embedded in one side of each clamping block. The clamping blocks are arranged, so that when the chains are pulled due to impact on the outer side of a ditcher, the traction force between the chains can be increased through the clamping blocks; and the friction between the clamping blocks can be increased through the clamping grooves so that the stability between the chains can be improved, and the phenomenon that the chains are broken due to mismatching between low rotating speed and hightorque of the chains can be avoided.

Description

technical field [0001] The invention belongs to the technical field of agricultural ditching, and in particular relates to a ditching machine chain. Background technique [0002] Agricultural ditching usually uses ditching machines for ditching, and ditching machines are usually divided into three types, small excavators for excavation, small chains installed and dragged on large tractors, and disc type ditchers. When the ditching machine is ditching, due to the existence of certain rocks inside the soil, the ditching head is easily damaged when the ditching machine is ditching. Due to the high output speed of the ditching machine, the low speed of the chain is high. If the torque does not match, it is easy to cause the chain to break and the efficiency is low. [0003] For example, the patent application number CN201510411970.5 discloses a safety protection chain, including inner chain plates connected head to tail, outer chain plates, rollers and pin shafts, and the two s...

Problems solved by technology

[0007] In order to solve the above technical problems, the present invention provides a protective structure for agricultural ditching machine chains, to solve the problem that after the existing chain is installed inside the crawler belt, the ditching machine is used on agricultural land, so that when the ditching machine excavates the soil , there are certain stones inside the soil, and one side of the ditching machine is stuck with the stones, causing the chain to be pulled and the chain broken, which leads to the existing chain being easily broken due to pulling, and the existing chain is impacted on the outside , because the connection between the chains is usually connected by bearings, so that when the existing chain is hit by stones at the lower end, the chain is easily damaged
