Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0029] Please refer to Figs. 1-4, the present application provides a technical solution: a steering device of a hydraulic drive machine plough, comprising a steering wheel 1, further comprising an adjusting mechanism 5, a silt prevention mechanism 6 and a protection mechanism 7, the bottom middle of the steering wheel 1 is fixedly connected with a steering frame 2, the inside lower side of the steering frame 2 is provided with a mobile front wheel 3, and the outer side of the mobile front wheel 3 is fixedly connected with a fixed paddle 4.

[0033] When the machine plough encounters wheel slip, the front wheel of the machine plough cannot effectively control the direction at this time, and the rear drive wheel rotates at high speed, it is judged that the machine plough front wheel cannot effectively grip the soil due to the relatively thin mud, which causes the vehicle to be unable to walk, at this time, the electric telescopic rod one 503 is controlled to work, when the electric telescopic rod one 503 works, the lifting frame 504 is pushed, so that the moving dial plate 505 on the lifting frame 504 is exposed from the rectangular groove on the outer side of the moving front wheel 3, at the same time, when the lifting frame 504 rises, the outer expansion frame 507 is moved by the spring 506, when the outer expansion frame 507 moves, the outer expansion plate 508 moves outward on the outer side of the moving front wheel 3, which increases the overall profile of the outer side of the moving front wheel 3, so that the force when the moving front wheel 3 contacts the soil is greater, which is convenient for the moving front wheel 3 to directly rise from the relatively shallow mud, so that the front wheel of the machine plough can be directly pulled out of the mud, and the machine plough can work normally.

[0034] Please refer to FIG.5-7, the present application provides technical scheme: anti-mud mechanism 6 includes moving groove 601, electric telescopic rod two 602, moving guide frame 603, adjusting plate 604, drive frame 605, outer expansion arc plate 606 and positioning frame 607, moving groove 601 is fixedly connected to the middle of the front of the outer expansion plate 508, electric telescopic rod two 602 is fixedly connected to the middle of the bottom of the moving groove 601, moving guide frame 603 is fixedly connected to the top of the electric telescopic rod two 602, adjusting plate 604 is rotationally connected to the front of the moving guide frame 603, drive frame 605 is rotationally connected to the side away from the moving guide frame 603 of the adjusting plate 604, outer expansion arc plate 606 is fixedly connected to the top of the drive frame 605, and positioning frame 607 is fixedly connected to the top of the front of the outer expansion plate 508.

[0036] The hard rubber tread 704 is arranged in the fixed clamping groove and fixedly connected to the inner wall of the mobile front wheel 3, so that the hard rubber tread 704 can be fixed.

[0037] According to the technical scheme, the rear side of the outer expansion arc plate 606 is rotationally connected to the middle part of the positioning frame 607, the top of the electric telescopic rod two 602 penetrates through the bottom of the moving groove 601 and extends into the moving groove 601 and is fixedly connected to the bottom of the moving guide frame 603, and the outer side of the moving guide frame 603 is slidingly connected to the inner wall of the moving groove 601, so that the moving guide frame 603 can slide in the moving groove 601.

[0038] According to the technical scheme, the outer expansion arc plate 606 is an arc plate, and the outer side of the outer expansion arc plate 606 is provided with a friction strip, so that the friction force when the outer expansion arc plate 606 contacts the mud can be increased.

[0039] When the silt is thick and the front wheel of the boat is sunk in the silt and cannot normally walk, on the basis of expanding the outer profile of the mobile front wheel 3, the electric telescopic rod two 602 is controlled to work, the electric telescopic rod two 602 pushes the moving guide frame 603, the moving guide frame 603 extrudes the adjusting plate 604 when being pushed, the adjusting plate 604 pushes the driving frame 605, at this time, the outer expansion arc plate 606 rotates in the positioning frame 607, the outer expansion arc plate 606 is flush with the edge of the outer expansion plate 508, the contact area of the whole mobile front wheel 3 with the silt is increased, at the same time, the friction strip on the outer side of the outer expansion arc plate 606 contacts the silt, further providing the grip force, so that the silt can be directly extruded, and the boat can normally move and work.

[0040] When the soil in the paddy field is relatively dry, the fixed paddle 4 outside the moving front wheel 3 and the moving paddle 505 are prone to be stuck with stones and hard soil, causing the boat to be unable to move normally. At this time, the electric telescopic rod one 503 is controlled to work, so that the electric telescopic rod one 503 drives the lifting frame 504 and the moving paddle 505 to move downward, so that the moving paddle 505 is stored in the moving front wheel 3. At this time, the moving paddle 505 is flush with the rectangular groove outside the moving front wheel 3, and the lifting frame 504 extrudes the air bag 701. When the air bag 701 is extruded, the air in the air bag 701 is introduced into the shunt pipe 703 through the connecting pipe frame 702, so that the air in the shunt pipe 703 is filled into the hard rubber tread 704, so that the hard rubber tread 704 is exposed from the fixed clamping groove. At this time, the moving paddle 505 is stored in the moving front wheel 3, which increases the distance between the fixed paddle 4 outside the moving front wheel 3 and the fixed paddle 4, so that the stones and hard soil can directly fall off. At the same time, the hard rubber tread 704 is exposed from the outside of the moving front wheel 3. When the hard rubber tread 704 outside the moving front wheel 3 contacts the protruding ground, the friction between the moving front wheel 3 and the ground can be increased, so that the boat can move out of the hard soil and avoid being stuck. The boat can adapt to various paddy fields and improve the work efficiency.
