[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] In order to solve the problem of how to effectively clean up the technology, such as Figure 1-4 As shown, the following preferred technical solutions are provided:

[0021] A bulldozer device for an excavator includes a bulldozer 1, wherein the front end surface of the bulldozer 1 is provided with a curved scraper 7, a first screw rod 3 is provided on one side of the upper end of the curved scraper 7, a first motor 4 is provided at one end of the first screw rod 3, a U-shaped scraper 10 is sleeved on the outer side of the curved scraper 7, a second screw rod 9 is passed through the middle of the U-shaped scraper 10, a second motor 8 is provided at the upper end of the second screw rod 9, telescopic scrapers 11 are symmetrically provided inside the two ends of the U-shaped scraper 10, a spring 13 is provided at the inner end of the telescopic scraper 11, and a ball 15 is rotatably provided inside the outer end of the telescopic scraper 11.

[0022] Specifically, when the bulldozer 1 is working, if the front end surface is attached with thick soil, the first motor 4 is started, the first motor 4 drives the first screw 3 to rotate, and drives the arc scraper 7 to move back and forth horizontally to remove the soil attached to the front end surface of the bulldozer 1. After the soil is cleaned, the first motor 4 is turned off. If thick soil is also attached to both sides of the arc scraper 7, the second motor 8 is started, the second motor 8 drives the second screw 9 to rotate, and drives the U-shaped scraper 10 to move back and forth vertically to remove the soil on both sides of the arc scraper 7. The U-shaped scraper 10 is a curved structure, and the spring 13 pushes the ball 15 at the front end of the telescopic scraper 11 to contact the curved surface of the front end of the bulldozer 1. Therefore, when the U-shaped scraper 10 is raised or lowered, the spring 13 reciprocates in compression and extension, always driving the ball 15 to contact the curved surface of the front end of the bulldozer 1, so that the length of the telescopic scraper 11 continuously changes to adapt to the width changes of the two sides of the curved scraper 7. This ensures that the U-shaped scraper 10 and the telescopic scraper 11 can effectively remove the soil on both sides of the curved scraper 7. Here, the ball 15 can reduce the resistance encountered when the U-shaped scraper 10 is raised or lowered. The purpose of this design is to effectively remove the soil on the front end of the bulldozer 1 and on both sides of the curved scraper 7, with simple operation and good results.

[0023] Further, such as Figure 1 and Figure 2 As shown, the following preferred technical solutions are provided:

[0024] A rectangular groove 2 is provided on the upper end surface of the bulldozer 1, and the first motor 4 is fixedly mounted on the inner wall of the rectangular groove 2 and the output end is fixedly connected to the end of the first screw rod 3. The outer side of the first screw rod 3 away from the first motor 4 is rotatably connected to the side wall of the rectangular groove 2 through a bearing, and a slider 5 is slidably connected to the inner surface of the rectangular groove 2. The first screw rod 3 is threadedly connected to the middle part of the slider 5, and the slider 5 and the arc scraper 7 are fastened together by a U-shaped plate 6. The rear end of the arc scraper 7 is in contact with the front end surface of the bulldozer 1. The purpose of this design is that the first motor 4 drives the first screw rod 3 to rotate, thereby driving the arc scraper 7 to move horizontally back and forth linearly.

[0025] Further, such as Figure 1-4 As shown, the following preferred technical solutions are provided:

[0026] The inner side of the U-shaped scraper 10 is slidingly connected to the outer side of the arc-shaped scraper 7. The second motor 8 is fixedly installed on the upper side of the front end of the arc-shaped scraper 7 and the output end is fixedly connected to the upper end of the second screw rod 9. The second screw rod 9 is threadedly connected to the middle part of the U-shaped scraper 10. The purpose of this design is that the second motor 8 drives the second screw rod 9 to rotate, driving the U-shaped scraper 10 to perform vertical lifting and lowering movements.

[0027] Further, such as Figure 4 As shown, the following preferred technical solutions are provided:

[0028] Slide grooves 12 are symmetrically opened inside the two ends of the U-shaped scraper 10. The outer side of the telescopic scraper 11 is slidably connected to the inner surface of the slide groove 12, and the spring 13 is fastened between the inner end of the telescopic scraper 11 and the inner wall of the slide groove 12. The purpose of this design is to ensure that the telescopic scraper 11 can be retracted under the action of the spring 13.

[0029] Further, such as Figure 4 As shown, the following preferred technical solutions are provided:

[0030] A spherical groove 14 is provided inside the outer end of the telescopic scraper 11, and a ball 15 is connected to the spherical groove 14 for rolling. The purpose of this design is to ensure that the ball 15 can roll and reduce the resistance encountered by the U-shaped scraper 10 when it is lifted or lowered.

[0031] Further, such as Figure 1-4 As shown, the following preferred technical solutions are provided:

[0032] The ball 15 is always in rolling contact with the front end surface of the bulldozer blade 1. The purpose of this design is to ensure a reasonable structure so that the soil on both sides of the arc scraper 7 can be effectively removed.

[0033] In summary: when the bulldozer 1 is working, if the front end surface is attached with thick soil, the first motor 4 is started, the first motor 4 drives the first screw 3 to rotate, and drives the arc scraper 7 to move horizontally in a reciprocating linear motion to remove the soil attached to the front end surface of the bulldozer 1. After the soil is cleaned, the first motor 4 is turned off. If thick soil is also attached to both sides of the arc scraper 7, the second motor 8 is started, the second motor 8 drives the second screw 9 to rotate, and drives the U-shaped scraper 10 to move vertically in a reciprocating linear motion to remove the soil on both sides of the arc scraper 7. The U-shaped scraper 10 is a curved structure, and the spring 13 pushes the ball 15 at the front end of the telescopic scraper 11 to contact the curved surface of the front end of the bulldozer 1. Therefore, when the U-shaped scraper 10 is raised or lowered, the spring 13 reciprocates in compression and extension, always driving the ball 15 to contact the curved surface of the front end of the bulldozer 1, so that the length of the telescopic scraper 11 continuously changes to adapt to the width changes of the two sides of the curved scraper 7. This ensures that the U-shaped scraper 10 and the telescopic scraper 11 can effectively remove the soil on both sides of the curved scraper 7. Here, the ball 15 can reduce the resistance encountered when the U-shaped scraper 10 is raised or lowered. The purpose of this design is to effectively remove the soil on the front end of the bulldozer 1 and on both sides of the curved scraper 7, with simple operation and good results.
