Implement Lifting Systems for Farm Machinery

Abstract

The invention discloses a farm tool lifting system for a farming machine. The farm tool lifting system comprises an oil pump, an oil tank, a rotating arm, a connecting rod, a lift oil cylinder and a first three-position four-way electromagnetic reversing valve. One end of the rotating arm is installed on a farming machine body, and the other end of the rotating arm is connected with one end of the connecting rod. The other end of the connecting rod is connected with a farm tool frame, and the stretching end of the lift oil cylinder is connected to the middle of the rotating arm. A cylinder body part of the lift oil cylinder is installed on the farming machine body. The output end of the oil pump is communicated with an opening P of the first three-position four-way electromagnetic reversing valve, and an opening A of the first three-position four-way electromagnetic reversing valve is communicated with a retracting cavity of the lift oil cylinder. An opening B of the first three-position four-way electromagnetic reversing valve is communicated with an extending cavity of the lift oil cylinder, and an opening T of the first three-position four-way electromagnetic reversing valve is communicated with the oil tank. A hydraulic lifting mechanism composed of the rotating arm, the connecting rod and the lift oil cylinder is used for adjusting the working height of a farm tool, and the labor intensity of workers is relieved. Due to the first three-position four-way electromagnetic reversing valve, the hydraulic lifting mechanism is automatically controlled, operation of the workers is simplified, and the farm tool lifting system is suitable for the farming machine.

Description

technical field [0001] The invention relates to a lifting system for agricultural machinery, in particular to an agricultural tool lifting system for agricultural machinery. Background technique [0002] At present, with the rapid development of science and technology, agricultural machinery has been widely used in farmland operations, and more and more agricultural tools are equipped on agricultural machinery, such as plows, harrows and plows. However, since these agricultural implements are generally simply hinged to the rear of the farming machine, when the working height of the agricultural implement needs to be adjusted according to the foot depth of the field, the operating height of the agricultural implement is usually adjusted manually, which is very cumbersome and laborious to operate. low efficiency. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the above-mentioned background technology, and provide ...
