A single-cylinder grabbing device applied to excavator operations in saltworks

Abstract

A single oil cylinder type material grabbing device applied to salt field excavator operation is characterized in that when a piston rod of an oil cylinder is in an upward-shrinking state, because the head end of the piston rod is braked through a transverse positioning shaft, a cylinder barrel of the oil cylinder can only move upwards; by means of the upward movement action of the cylinder barrel of the oil cylinder, the position of a bucket body oblique pull steel plate is lifted upwards through a main shaft sleeve in series connection with an auxiliary pin shaft; the bucket body oblique pull steel plate moves upwards to obliquely pull two shoulder plates in a material grabbing mechanism through a pin rod; and after the two shoulder plates bear force, two left and right bucket bodies in the material grabbing mechanism are controlled to achieve sector-shaped opening with a main pin shaft as the axis. The single oil cylinder type material grabbing device applied to salt field excavator operation has the beneficial effects of being novel in structure, light in weight, capable of greatly reducing the manufacturing cost and making the material grabbing or material releasing action more coordinated and high in operation efficiency.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and relates to a single oil cylinder grabbing device applied to excavator operations in salt fields. Background technique [0002] At present, the grab buckets used by excavators operating in salt fields generally adopt a double-cylinder structure. The grab buckets with this double-cylinder structure will have problems of heavy weight and high manufacturing cost during actual use. In addition, due to each The oil cylinder is only responsible for controlling the left half or the right half of the grab hopper body, so through double oil cylinders to control the left half or right half of the grab hopper body respectively, there will be synchronization of the opening / closing of the grab hopper body performance is poor, thereby affecting the work efficiency. Contents of the invention [0003] In order to solve the above problems, the present invention provides a single-cylinder type grabbing ...
