Problems solved by technology

[0005] In view of the high requirements for the use of the existing organic fertilizer turning and throwing machine, it is impossible to realize the light and simplified compost utilization of agricultural and animal husbandry waste on the spot. When working on an uneven field, it is very easy to cause damage to the tool due to incomplete turning and throwing or the rotating knife shaft touching the ground. The purpose of this invention is to provide a hydraulic system of an organic fertilizer turning and throwing machine and an organic fertilizer turning and throwing machine, which can realize the height adjustment of the left and right walking devices of the turning and throwing machine, adapt to complex work sites, ensure the turning and throwing effect, and protect the knives not damaged

Abstract

The invention discloses a hydraulic control system of an organic fertilizer turner and the organic fertilizer turner, belongs to the technical field of agricultural machinery, and can realize independent adjustment of the height of a left and right walking device of the turner, adapt to complex working places, ensure the turning effect and protect a cutter from being damaged. The hydraulic controlsystem comprises a power unit, an execution unit, a first control unit and a second control unit, and the power unit is used for providing a hydraulic oil source and converting mechanical energy of apower output device into hydraulic energy; the execution unit comprises a walking hydraulic motor and a plurality of hydraulic oil cylinders; the first control unit comprises a proportional valve bank, the proportional valve bank divides hydraulic oil injected by the power unit into a plurality of oil ways, and the tail end of each oil way is communicated with a hydraulic oil cylinder or the walking hydraulic motor; the second control unit comprises an electromagnetic valve set, the electromagnetic valve set divides hydraulic oil input by the power unit into a plurality of oil ways, and the tail ends of the oil ways are all communicated with a hydraulic oil cylinder. The electromagnetic valve set further communicates with the hydraulic motor to assist in adjusting the rotating speed of the walking hydraulic motor.

Description

Technical field[0001]The invention belongs to the technical field of agricultural machinery, and specifically relates to a hydraulic control system of an organic fertilizer turning and throwing machine and an organic fertilizer turning and throwing machine.Background technique[0002]The statements here only provide background art related to the present invention, and do not necessarily constitute prior art.[0003]At present, the treatment of agricultural and animal husbandry wastes such as rural straw and manure needs to be solved urgently. At present, the most economical and environmentally friendly treatment method is to simplify the use of compost on the spot.[0004]The inventor understands that the existing turning and throwing machine is mainly suitable for hardened standard sites, and cannot realize the in-situ light and simplified compost utilization of agricultural and animal husbandry waste. Moreover, the initial investment is relatively high, which is not suitable for small-s...
