Description
Technical field
The utility model relates to a kind of engineering mechanical device, especially relates to a kind of bulldozer.
Background technology
Bulldozer is one of modal equipment in engineering construction, and it is mainly used in earthwork, as mound, fill and lead up, in the operation such as cubic metre of earth transfer, the bulldozer equipment that is absolutely necessary.Existing bulldozer generally all is made of car body and bulldozing device, and bulldozing device comprises a dozer, and dozer is the integral type structure, for the different operating condition that adapts to, and the lifting that it generally can be suitable, and can carry out the adjustment at certain elevation angle.But in dozing, what have need to push away earth forward, and what have need to push earth open to both sides, and the needs that also have will be pushed a side to by earth.Need for these diversified operations, existing bulldozer uses sometimes trouble very, one side particularly need earth to both sides or when pushing away, need to repeatedly advancing, retreat, turning and just can complete by bulldozer.Therefore, all very wastes of its operating time and energy.The Chinese patent that is CN102330440 as publication number discloses a kind of bulldozer universal shovel mechanism, the segmental support that comprises universal shovel, connects with universal sliding tackle, with universal shovel and the segmental support angling cylinder that connects of ball and the lift cylinder hinged with the frame of segmental support and bulldozer respectively respectively, also comprise respectively connecing with segmental support and universal sliding tackle, and the adjustable adjusting strut of axial length.The bulldozer universal shovel mechanism that the utility model provides, the extension elongation of the cylinder rod by controlling lift cylinder, can realize the shovel blade mechanism lifting action, the extension elongation of the cylinder rod by controlling angling cylinder, can realize shovel blade mechanism revolution action, can guarantee that therefore universal shovel completes lifting and gyration.The utility model is regulated the extension elongation of strut by adjusting, the penetrating angle of universal shovel is regulated, and can adjust the dozer penetrating angle according to different operating modes thereby be convenient to the driver.This patent is attempted the flexibility by the angle of penetration that improves dozer, improves bulldozer to the adaptive capacity of different operating modes.But it does not still break away from the soil-shifting function of single angle.
Summary of the invention
The utility model is mainly that the existing soil-shifting angle of solution prior art is single, push away and operation during to a thruster mud bothers very much dividing to both sides, energy consumption is than the high-technology problem, provide a kind of and can simply carry out forward, to both sides, change to the mode of operation of a thruster soil, and all very convenient under various soil-shifting forms, efficient is high, the multi-functional bulldozer at the bottom of energy consumption.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of multi-functional bulldozer, comprise car body, shovel frame and dozer, it is characterized in that described dozer is made of left shovel body and right shovel body, left and right shovel body is hinged with a rotating shaft of being located at its rear side respectively, this rotating shaft is connected with the shovel frame, left and right shovel body is rotationally connected with left push rod, right push rod respectively, and left and right push rod is rotationally connected with described shovel frame respectively.Elongate or shorten by left and right push rod, angle that can the left and right shovel body of conversion, thus make left and right shovel body consist of horizontal " one " font or V-type, also can be so that left and right shovel body tilts to the same side.The angle of above-mentioned these left and right shovel bodies changes can be made respectively it reach forward to bulldoze, divide to both sides soil or to the effect of a thruster soil, and adjusts very conveniently, has reached energy-conservation, efficient purpose.
As preferably, the hinged place of described left shovel body and right shovel body or left shovel body or right shovel body and rotating shaft is provided with pressure sensor, and this pressure sensor is connected with a controller.According to this technical scheme, can be respectively equipped with pressure sensor on left shovel body and right shovel body, also can be provided with pressure sensor on left shovel body or right shovel body.Can set a force value to controller, when the pressure of pressure sensor acquisition reaches this force value, illustrate that dozer is stressed excessive, at this moment, the outer end of controlling left shovel body and right shovel body by controller is to angle of post deflection, and left and right shovel body forms wedge angle V font forward, and can reduce the resistance that bulldozer advances this moment, after certain hour, left and right shovel body returns to initial position.
As preferably, front side between described left and right shovel body is provided with a soil-shifting backplate, this soil-shifting backplate is made of left plate body and right panel body, the angle that has one 60-120 ° between left and right plate body, and wedge angle one side forward, soil-shifting backplate rear side is provided with connecting rod, and the gap that this connecting rod passes between left and right shovel body is connected with described rotating shaft.
The utility model also provides following using method, and it comprises following process:
1, when needs are bulldozed forward, controller is controlled left and right push rod, so that left and right shovel body everywhere on same straight line, is pushed ahead;
2, the pressure that obtains when the pressure pressure difference transmitter reaches or during greater than setting value, controller is namely controlled left and right push rod and shunk, so that left and right shovel body consists of the angle of 90 °-120 °, thereby reduces the resistance that dozer advances;
3, advance one with the angle of 90 °-120 ° at left and right shovel body adjust the period after, controller extends left and right push rod again, so that left and right shovel body returns on same straight line;
4, in the time need to bulldozing to the both sides of car body, controller is controlled the left and right push rod, so that left and right shovel body consists of the angle of 45 °-90 °, pushes ahead;
5, when need to be to the left side of car body or the right when bulldozing, controller be controlled the left and right push rod so that left and right shovel body tilts to same direction, and with the angle of-90 ° at 45 ° of car body direction of advance structure.
The beneficial effect that brings of the present utility model is, solved the existing soil-shifting angle of prior art single, push away and operation during to a thruster mud bothers very much dividing to both sides, energy consumption is than the high-technology problem, realized a kind ofly can simply carrying out forward, to both sides, change to the mode of operation of a thruster soil, and all very convenient under various soil-shifting forms, efficient is high, the multi-functional bulldozer at the bottom of energy consumption.
