Description

Technical Field

[0001] The invention belongs to the technical field of building construction, in particular to a convenient and efficient bulldozer for building construction. Background Art

[0002] In the field of construction, bulldozer operation is a basic and important link. With the acceleration of urbanization, a large number of construction projects have emerged around the world, from large-scale urban complexes, including the concentrated development of multifunctional buildings such as residential, commercial, and office, to infrastructure construction, such as the construction and expansion of highways, railways, airports, ports, etc. These projects all involve large-scale earthworks, that is, the leveling of the land and the movement of earth, and bulldozers are usually required in the work process.

[0003] Most of the existing construction bulldozers have fixed bulldozer blades. In large-scale bulldozer operations, due to the fixed width of the bulldozer blade, the area that can be covered by a single bulldozer is limited, resulting in multiple round trips to complete the task. A lot of time is spent on the round trip, which greatly reduces the bulldozer efficiency. At the same time, the bulldozer blade is usually only a solid plate. When encountering hard soil, it is often difficult for the bulldozer blade to effectively cut into the soil, and generally only has a simple bulldozer function, without a special structure for breaking hard blocks or rocks. When encountering soil containing small rocks or hard blocks, the bulldozer equipment cannot effectively deal with these obstacles, resulting in the inability to carry out the bulldozer operation smoothly. Therefore, a convenient and efficient construction bulldozer is proposed. Summary of the invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention facilitates the adjustment of the size of the bulldozing blade by arranging the coordination of structures such as the movable bulldozing blade and the fixed bulldozing blade. When a large area of ​​bulldozing is required, the first motor can be started to rotate the gear. The rotation of the gear will drive the two movable bulldozing blades to move away from each other through the two racks, so that the two movable bulldozing blades extend from the inside of the fixed bulldozing blade to the two sides of the fixed bulldozing blade, so that the movable bulldozing blades are unfolded, the single bulldozing amount is increased, the speed of land leveling is significantly accelerated, the overall construction efficiency is improved, and the number of round trips is reduced, so that the time required for the entire bulldozing operation is greatly shortened.

[0018] The present invention facilitates the crushing of hard soil by setting up the cooperation of structures such as the soil-breaking tooth plate and the cam. When encountering hard soil or obstacles such as rocks, the second motor is started to rotate the cam. When the protruding part on the cam rotates to a position abutting against the connecting frame, it will squeeze the connecting frame in the direction away from the cam, causing the connecting frame to slide in the groove in the direction away from the first motor, squeezing the spring and driving the soil-breaking tooth plate to move out of the groove, so that it cuts into the soil or crushes small pieces of rock, making it easier for the bulldozer to push the soil, thereby improving the adaptability of the bulldozer equipment to complex soil. When the cam continues to rotate, it will drive its protruding part to release the abutment with the connecting frame. At this time, the connecting frame will reset under the action of the spring elastic force, so that the hard soil is broken and vibrated reciprocatingly through the soil-breaking tooth plate, which can destroy the cohesive force between soil particles, making them loose and easier to be pushed by the bulldozer, thereby improving the overall efficiency of bulldozing.

The movable bulldozer plates 104 are provided with first sliding grooves 106 inside, and the sides of the two movable bulldozer plates 104 that are close to each other are provided with rotating grooves 107.

[0029] The two rotating grooves 107 are combined to form a circular groove, the gear 102 passes through the side of the movable bulldozer plate 104 close to the protrusion 105 and extends to the inside of the circular groove, the gear 102 is rotationally connected to the circular groove, the rack 103 is slidingly connected to the first slide groove 106, and the first slide groove 106 is communicated with the rotating groove 107.

[0032] The above scheme is adopted: by setting the coordination of structures such as the movable bulldozing plate 104 and the fixed bulldozing plate 201, it is convenient to adjust the size of the bulldozing plate. When a large area of ​​bulldozing is required, the first motor 101 can be started to rotate the gear 102.

At the same time, at the edge or corner of the site, the movable bulldozing plate 104 can be appropriately retracted or unfolded as needed, so that the bulldozing operation can better fit the site boundary, and when bulldozing in a narrow space, the movable bulldozing plate 104 can be put away to adapt to different site requirements and improve the adaptability of the device.

[0033] like Figures 1 to 4As shown, the earth-breaking mechanism 3 includes two second motors 301, and a cam 302 is rotatably connected to the second motor 301. The side of the cam 302 abuts against the connecting frame 303, and a plurality of earth-breaking tooth plates 304 are fixedly connected to the connecting frame 303. A plurality of springs 305 are fixedly connected to the side of the connecting frame 303 away from the cam 302. The plurality of earth-breaking tooth plates 304 are evenly distributed on the side of the connecting frame 303 away from the second motor 301, and the plurality of earth-breaking tooth plates 304 are all located between the plurality of springs 305. The material of the earth-breaking tooth plates 304 is a high-strength wear-resistant material.

[0034] The connecting frame 303 is slidably connected to the inner wall of the fixed bulldozer plate 201, the breaking tooth plate 304 is slidably connected to the groove 202, the side of the connecting frame 303 away from the second motor 301 is elastically connected to the inner wall of the groove 202 through the spring 305, a plurality of breaking tooth plates 304 respectively penetrate the breaking tooth plates 304 and extend to the side of the fixed bulldozer plate 201 away from the rotating frame 205, the second motor 301 is fixedly connected to the inner wall of the fixed bulldozer plate 201, and the cam 302 is rotatably connected to the inner wall of the fixed bulldozer plate 201.

[0035] The main mechanism 4 includes a bulldozer 401 , both sides of which are rotatably connected to two wheels 402 , on which tracks 403 are provided, and four hydraulic cylinders 207 are rotatably connected to the bulldozer 401 and the wheels 402 at one end away from the telescopic rod 206 .

[0036] The above scheme is adopted: by setting the cooperation of the structures such as the earth-breaking tooth plate 304 and the cam 302, it is convenient to break the hard soil. When encountering hard soil or obstacles such as rocks, the second motor 301 is started to rotate the cam 302. When the protruding part on the cam 302 rotates to a position against the connecting frame 303, it squeezes the connecting frame 303 in the direction away from the cam 302, so that the connecting frame 303 slides in the groove 202 in the direction away from the first motor 101, squeezing the spring 305 and driving the earth-breaking tooth plate 304 to move away from the first motor 101. The groove 202 is moved outward to cut into the soil or break small pieces of rock, making it easier for the bulldozer to push the soil, thereby improving the adaptability of the bulldozer to complex soils. When the cam 302 continues to rotate, its protruding part will be released from the contact with the connecting frame 303. At this time, the connecting frame 303 will be reset under the action of the elastic force of the spring 305, so that the hard soil can be broken and vibrated through the soil breaking tooth plate 304, which can destroy the cohesive force between the soil particles, making them loose and easier to be pushed by the bulldozer, thereby improving the overall efficiency of the bulldozer.

[0037] Working principle and use process of the present invention: Under normal working conditions, the staff can drive the bulldozer 401 to move to the construction site, and then use the hydraulic cylinder 207 to extend and retract the telescopic rod 206 to adjust the angle of the fixed bulldozer plate 201 so that it can adapt to the terrain. For example, in a site with a slope, the bulldozer can better fit the slope surface for bulldozing operations, thereby improving the efficiency and quality of bulldozing.

[0038] When bulldozing over a large area is required, the first motor 101 can be started to rotate the gear 102. The rotation of the gear 102 will drive the two movable bulldozing plates 104 to move away from each other through the two racks 103, so that the two movable bulldozing plates 104 extend from the inside of the fixed bulldozing plate 201 to the two sides of the fixed bulldozing plate 201. The movable bulldozing plates 104 can be deployed to increase the amount of bulldozing per time.

[0039] When encountering hard soil or obstacles such as rocks, the second motor 301 is started to rotate the cam 302. When the protruding part on the cam 302 rotates to a position abutting against the connecting frame 303, the connecting frame 303 will be squeezed in the direction away from the cam 302, causing the connecting frame 303 to slide in the groove 202 in the direction away from the first motor 101, squeezing the spring 305 and driving the breaking tooth plate 304 to move out from the groove 202, so that it cuts into the soil or breaks small pieces of rock, making it easier for the bulldozer to push the soil, thereby improving the adaptability of the bulldozer equipment to complex soil. When the cam 302 continues to rotate, its protruding part will be driven to release the contact with the connecting frame 303. At this time, the connecting frame 303 will be reset under the action of the elastic force of the spring 305, thereby reciprocating through the breaking tooth plate 304 to break the hard soil and apply vibration, destroying the cohesive force between the soil particles, making it loose and easier to be pushed by the bulldozer.
