Technical Field
The utility model relates to an sanitation equips the field, especially relates to breaker's hydraulic system for road surface cleaning vehicle.
Background
The sanitation vehicle is a special sanitation vehicle which is generally refitted by a shaping type II chassis, garbage and dust are collected by utilizing the vacuum adsorption effect, and a leaf crushing device is used as a matching device of part of sanitation vehicles and needs to have the function of being additionally installed or detached at any time. The hydraulic system of numerous optional crushing devices in the current market achieves the effect of controlling the crushing motor by increasing a plurality of groups of electromagnetic valves, the cost of the whole hydraulic system is invisibly increased, and more importantly, the hydraulic system of the crushing device is more complicated to install or disassemble.
Disclosure of Invention
An object of the utility model is to provide a breaker's hydraulic system for road surface cleaning vehicle satisfies the installing additional of breaker or dismantle the requirement under the unchangeable prerequisite of hydraulic pressure valves quantity, has reduced the hydraulic system cost, has also increased the commonality of hydraulic system integrated package simultaneously.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the hydraulic system of the crushing device for the road cleaning vehicle comprises a crushing motor, a sweeping disc motor and a three-position Y-shaped reversing valve,
a port P of the three-position Y-shaped reversing valve is connected to an oil outlet of the oil pump, an oil inlet of the oil pump is connected to the oil tank, a port T of the three-position Y-shaped reversing valve is connected to the oil tank, a port A of the three-position Y-shaped reversing valve is connected to an oil inlet of the crushing motor, an oil outlet of the crushing motor is connected to an oil inlet of the sweeping disc motor through a first one-way valve, a forward flow end of the first one-way valve is connected with the oil outlet of the crushing motor, a port B of the three-position Y-shaped reversing valve is connected to an oil inlet of the sweeping disc motor through a second one-way valve, and a forward flow end of the second one-;
an oil outlet of the sweeping disc motor is connected to an oil tank;
and a T port of the three-position Y-shaped reversing valve is connected to an oil tank.
The first one-way valve and the second one-way valve are respectively a through one-way valve.
The crushing motor comprises a left crushing motor and a right crushing motor which are connected in sequence.
The sweeping disc motor comprises a left sweeping disc motor and a right sweeping disc motor which are sequentially connected.
The utility model adopts the above technique, following beneficial effect has: the utility model discloses can sweep under the prerequisite of set motor action, through a tribit Y type switching-over valve, reach the purpose of control breaker function simultaneously not influencing control. By means of the two one-way valves, the mutual influence between the sweeping disc motor and the crushing motor is avoided. No matter whether the crushing device is selected or not, the current hydraulic system integrated blocks, valve banks and the like applicable to the sanitation vehicle do not need to be changed, and the integrated blocks and the valve banks do not need to be additionally added.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments;
fig. 1 is a schematic view of the present invention.
Detailed Description
As shown in figure 1, the hydraulic system of the crushing device for the road cleaning vehicle of the utility model comprises a crushing motor, a sweeping disc motor and a three-position Y-shaped reversing valve 1,
a P port of the three-position Y-shaped reversing valve 1 is connected to an oil outlet of an oil pump 4, an oil inlet of the oil pump 4 is connected to an oil tank 5, a T port of the three-position Y-shaped reversing valve 1 is connected to the oil tank 5, an A port of the three-position Y-shaped reversing valve 1 is connected to an oil inlet of a crushing motor, an oil outlet of the crushing motor is connected to an oil inlet of a sweeping disc motor through a first one-way valve 3B, a forward flowing end of the first one-way valve 3B is connected with an oil outlet of the crushing motor, a B port of the three-position Y-shaped reversing valve 1 is connected to an oil inlet of the sweeping disc motor through a second one-way valve 3a, and a forward flowing end of the second one-way valve;
the oil outlet of the sweeping disc motor is connected to an oil tank 5;
and a T port of the three-position Y-shaped reversing valve 1 is connected to an oil tank 5.
The first check valve 3b and the second check valve 3a are straight check valves respectively.
The crushing motors comprise a left crushing motor 2a and a right crushing motor 2b connected in series.
The sweeping disk motor comprises a left sweeping disk motor 4a and a right sweeping disk motor 4b which are connected in sequence.
The utility model discloses a theory of operation: when the sanitation truck works but the crushing motor does not need to work, the right side of the three-position Y-shaped reversing valve 1 is electrified, pressure oil is led to the port B from the port P, the first one-way valve 3B blocks an oil path to drive the crushing motor, and a hydraulic system only controls the left sweeping disc motor 4a and the right sweeping disc motor 4B to operate; when the crushing motor needs to be started, the left side of the three-position Y-shaped reversing valve 1 is electrified, pressure oil is led to the port A from the port P to directly drive the left crushing motor 2a and the right crushing motor 2b to work, meanwhile, the second one-way valve 3a blocks the pressure oil return tank 5, and the pressure oil can continuously drive the left sweeping disc motor 4a and the right sweeping disc motor 4b to work.
When no crushing device system is selected, the port A of the three-position Y-shaped reversing valve 1 can be blocked, the three-position Y-shaped reversing valve 1 only controls the right side to be electrified or not electrified, and pressure oil is led to the port B from the port P, so that the purpose of only controlling the left sweeping disc motor 4a and the right sweeping disc motor 4B to operate is achieved.
The practice of the present invention has been described with reference to the accompanying drawings, but the invention is not limited to the embodiments described above, which are illustrative rather than limiting, and it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
