Abstract

A roller tractor synchronous hoisting pressed-into-soil hydraulic system comprises a hydraulic oil tank, an oil suction pipe, a lifting oil pump, a high-pressure oil pipe, a multiway valve, a right lifting oil cylinder, a left lifting oil cylinder, an upper connecting oil pipe, a lower connecting oil pipe and an oil cylinder stop valve. The hydraulic oil tank is connected with the lifting oil pump through the oil suction pipe on the right side of a tractor chassis. The lifting oil pump is connected with the multiway valve through the high-pressure oil pipe on the upper side of the tractor chassis. The multiway valve is arranged on the right lifting oil cylinder on the right side of the tractor chassis. The left lifting oil cylinder is arranged on the left side of the tractor chassis. A rodless cavity of the right lifting oil cylinder and a rodless cavity of the left lifting oil cylinder are connected through the upper connecting oil pipe. A rod cavity of the right lifting oil cylinder and a rod cavity of the left lifting oil cylinder are connected through the lower connecting oil cylinder. The oil cylinder stop valve is arranged in the right lifting oil cylinder. The roller tractor synchronous hoisting pressed-into-soil hydraulic system is simple in structure and convenient to mount, the using demands of synchronous hoisting and dropping of a tractor can be met, impact on the tractor in working is reduced, and the system reliability is effectively improved.

Description

Wheeled tractor promotes synchronously and suppresses the hydraulic system of burying
Technical field
The utility model belongs to the tractor field, relates to the lifting synchronously of a kind of wheeled tractor and suppresses the hydraulic system of burying.
Background technique
At present, in the large-scale wheeled tractor series that China produces, it suppresses the elevator system of burying, and has adopted two auxiliary cylinders, plays the effect of lifting and decline farm implements.Yet when the decline state, because two auxiliary cylinders can't realize fully synchronously, cause in the elevator system lifter housing to pull damage easily.In order to guarantee that two auxiliary cylinders can descend synchronously, need improve hydraulic system and auxiliary cylinder, thereby protection lifter housing is not damaged.
The model utility content
The purpose of this utility model is to provide a kind of reliable in structure, wheeled tractor easy to maintenance to promote synchronously and suppress the hydraulic system of burying, and promotes the usage requirement of suppressing the hydraulic system of burying synchronously to satisfy large power wheel tractor.
The technical solution of the utility model is: wheeled tractor promotes synchronously and suppresses the hydraulic system of burying, and comprising: hydraulic oil container, fuel sucking pipe, lifting oil pump, high-pressure oil pipe, multi-way valve, right lift cylinder, left lift cylinder, on connect oil pipe, connect oil pipe, oil cylinder stop valve down; On the right side of tractor chassis, hydraulic oil container is connected with the lifting oil pump by fuel sucking pipe; At the upside of tractor chassis, promote oil pump and be connected with multi-way valve by high-pressure oil pipe; On the right side of tractor chassis, multi-way valve is installed on the right lift cylinder; Left side lift cylinder is arranged in the left side of tractor chassis; Connect by last connection oil pipe between right lift cylinder rodless cavity and the left lift cylinder rodless cavity; Connect by connecting oil pipe down between right lift cylinder rod chamber and the left lift cylinder rod chamber; The oil cylinder stop valve is contained in the right lift cylinder.
The utility model can be reached following beneficial effect: this system architecture is simple, and is easy for installation, can satisfy the usage requirement that tractor promotes and descends synchronously, reduced the impact to tractor in the work, and system reliability effectively improves.
Description of drawings
Fig. 1 promotes the structural representation of suppressing the hydraulic system of burying synchronously for the utility model wheeled tractor;
Fig. 2 suppress for the utility model wheeled tractor promotes synchronously the hydraulic system of burying fundamental diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.Shown in Fig. 1, wheeled tractor promotes synchronously and suppresses the hydraulic system of burying, and comprising: hydraulic oil container 1, fuel sucking pipe 2, promote oil pump 3, high-pressure oil pipe 4, multi-way valve 5, right lift cylinder 6, left lift cylinder 7, on connect oil pipe 8, connect oil pipe 9, oil cylinder stop valve 10 down; Hydraulic oil container 1 is installed in the right side of tractor chassis by support, promotes oil pump 3 by the right side of pump shaft at tractor chassis; Both connect by fuel sucking pipe 2; Multi-way valve 5 is placed in the upside of tractor chassis; Promote between oil pump 3 and the multi-way valve 5 and be connected by high-pressure oil pipe 4; Right lift cylinder 6 is arranged in the right side of tractor chassis; Left side lift cylinder 7 is arranged in the left side of tractor chassis; Connect by last connection oil pipe 8 between right lift cylinder 6 rodless cavities and left lift cylinder 7 rodless cavities; Connect by connecting oil pipe 9 down between right lift cylinder 6 rod chambers and left lift cylinder 7 rod chambers; Oil cylinder stop valve 10 is contained in the right lift cylinder 6.
Its working procedure is as follows: when handling multi-way valve 5 to the lifting position, promote oil pump 3 and pass through fuel sucking pipe 2 from hydraulic oil container 1 oil suction, enter multi-way valve 5 by high-pressure oil pipe 4, multi-way valve 5 is fuel-displaced then towards right lift cylinder 6, enter by right lift cylinder 6 hydraulic fluid ports, through behind the right lift cylinder 6 rodless cavity inner cylinder stop valves 10, enter right lift cylinder 6 rodless cavities and enter left lift cylinder 7 rodless cavities by last connection oil pipe 8, make system improving; When handling multi-way valve 5 to the decline position, promote oil pump 3 and pass through fuel sucking pipe 2 from hydraulic oil container 1 oil suction, enter multi-way valve 5 by high-pressure oil pipe 4, multi-way valve 5 is fuel-displaced then towards right lift cylinder 6, simultaneously by between right lift cylinder 6 rod chambers and left lift cylinder 7 rod chambers by under connect oil pipe 9 and enter left lift cylinder 7 rod chambers, system is descended; Wait for when right lift cylinder 6 drops to certain position, right lift cylinder 6 inner cylinder stop valves 10 limited closing, two side cylinders are no longer action all.
Native system is simple in structure, and is easy for installation, can satisfy the usage requirement that tractor promotes and descends synchronously, reduced the impact to tractor in the work, improved the tractor reliability effectively.
