Whole-hydraulic spraying seeding machine slurry pump whole-hydraulic driving system

Abstract

The invention discloses a whole-hydraulic spraying seeding machine slurry pump whole-hydraulic driving system. A diesel engine providing piston power, a variable closed type pump converting the pistonpower into hydraulic force, a closed type motor for converting the hydraulic force into a rotating force, and a centrifugal pump used for slurry supercharging are included. The whole-hydraulic spraying seeding machine slurry pump whole-hydraulic driving system has the beneficial effects that the device is in a whole-hydraulic driving manner, and generation of initial power is achieved through a hydraulic machine; the power is converted into the hydraulic force through the closed type pump, power transmission between machines is completed through the hydraulic force, converting from the pistonpower to the rotating shaft power is completed, a small number of machines are adopted by the system as a whole, the structural composition is simple, and energy transmission manners are few; if a fault happens, the fault removing and repairing time can also be greatly shortened; meanwhile, due to the design of a wrinkle hose of a feeding pipe, the feeding pipe has the angle adjusting capacity, angle adjusting can be performed according to the specific using condition on the premise that the feeding pipe is not disassembled, and therefore a feeding angle can be adjusted according to a specific using environment.

Description

technical field [0001] The invention relates to a drive system, in particular to a fully hydraulic drive system for a mud pump of a fully hydraulic sprayer, belonging to the technical field of sprayer power drive equipment. Background technique [0002] During the working process of the sprayer, the mud to be sprayed needs to be pressurized by the mud pump to perform a series of power transmission, and finally sprayed to the designated area through the nozzle. This process involves the transformation of many energy forms, and finally transforms into the power of mud spraying, which is completed through the driving system of the mud pump. [0003] There are certain shortcomings in the design of the existing fully hydraulic driving system of the sprayer mud pump. The specific performance is as follows: First, the driving of the common sprayer mud pump is to transmit energy through a variety of machine structures, and the overall structure is relatively complicated. , There ar...

[0003] There are certain shortcomings in the design of the existing fully hydraulic driving system of the sprayer mud pump. The specific performance is as follows: First, the driving of the common sprayer mud pump is to transmit energy through a variety of machine structures, and the overall structure is relatively complicated. , There are many supporting machines, and the power loss between various equipment is relatively large, and once a failure occurs, its troubleshooting is a very large project. Secondly, the feeding process of the general sprayer mud pump is fixed, and its pipeline cannot Adjust according to the specific use environment. The centrifugal pump that provides the main power of the mud is easy to enter the air and damage the impeller.
