Technical Field

[0001] This utility model relates to the field of bulldozer technology, specifically to a bulldozing mechanism for a bulldozer. Background Technology

[0002] A bulldozer is an earthmoving machine capable of excavating, transporting, and dumping soil and rock, and it has a wide range of applications in open-pit mines. For example, it is used to construct spoil heaps, level truck spoil heaps, stockpile loose ore, level working platforms, and construct sites. It is used not only for auxiliary work but also for primary mining operations. A bulldozer scoops up soil with its bucket, moving it to a suitable location; therefore, a bulldozing mechanism is required.

[0003] When a bulldozer uses its bucket to push soil, large chunks of soil enter the bucket. When a large number of large chunks of soil accumulate, the spacing between them is relatively large, which cannot fully utilize the working space of the bucket, resulting in a decrease in the efficiency of the bucket's soil-moving function. Therefore, this does not meet the existing requirements. To address this, we have proposed a bulldozing mechanism for bulldozers. Utility Model Content

[0004] This utility model provides a bulldozing mechanism for a bulldozer, which can break up large clods of soil during the bulldozing process, making good use of the internal space of the bucket and improving the efficiency of bulldozing. It solves the problem mentioned in the background art that large clods of soil enter the bucket, and when a large number of large clods of soil are piled up, the spacing between the large clods is relatively large, which cannot fully utilize the working space of the bucket and leads to a decrease in the efficiency of the bucket.

[0005] This utility model provides the following technical solution: a bulldozing mechanism for a bulldozer, including a bulldozer and a bucket mounted on the bulldozer, wherein the bucket is provided with a crushing component for crushing large clods of soil inside the bucket;

[0006] The crushing assembly includes a rotating shaft rotatably mounted on the inner wall of the bucket cavity and several blades mounted on the rotating shaft.

[0008] As an optional embodiment of the bulldozing mechanism of the bulldozer described in this utility model, wherein: a snap-fit ​​assembly is provided on the rotating shaft;

[0009] The snap-fit ​​assembly includes a sliding groove formed on the rotating shaft and a mounting groove connected to the side wall of the sliding groove. A trapezoidal block is slidably disposed in the mounting groove, and a spring is fixedly connected between the trapezoidal block and the mounting groove. One end of the blade is slidably disposed in the sliding groove, and a snap-fit ​​groove is formed on the side wall of one end of the blade.

[0010] As an optional embodiment of the bulldozing mechanism of the bulldozer described in this utility model, wherein: the upper sidewall of the locking groove is set as an inclined surface, and the trapezoidal block is locked with the locking groove.

[0011] As an optional embodiment of the bulldozing mechanism of the bulldozer described in this utility model, a limiting groove is provided on the rotating shaft, the limiting groove is connected to the mounting groove, and a pulling column is fixedly installed at the upper end of the trapezoidal block, the pulling column being slidably disposed within the limiting groove.

[0013] This utility model has the following beneficial effects:

[0014] 1. During the process of bulldozing soil using the bucket, with the cooperation of the motor, rotating shaft and blades, large clods of soil in the bucket come into contact with the blades and are quickly broken into smaller soil particles. This achieves the effect of quickly breaking large clods of soil into smaller soil particles, making full use of the bucket's space and improving bulldozing efficiency.

[0015] 2. When the blade is damaged and needs to be replaced, with the cooperation of the sealing plate, mounting frame, magnetic block, pulling column, limiting groove, trapezoidal block and spring, the trapezoidal block is moved to the appropriate position and will disengage from the limiting groove on the blade. At this time, the blade can be separated from the rotating shaft, realizing the removal of the blade. When the blade needs to be installed, during the process of inserting the blade into the sliding groove, its end will squeeze the inclined surface of the trapezoidal block. The end of the blade will contact the bottom wall of the sliding groove. At this time, the trapezoidal block will be springed into the snap-fit ​​groove on the blade by the elastic force of the spring, thus completing the installation of the blade. This allows for quick installation and removal of the blade. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figure 1-2 A bulldozing mechanism for a bulldozer includes a bulldozer 1 and a bucket 2 mounted on the bulldozer 1. The bucket 2 is provided with a crushing component 3 for crushing large clods of soil inside the bucket 2.

[0025] The crushing component 3 includes a rotating shaft 32 rotatably mounted on the inner wall of the bucket 2 and several blades 33 mounted on the rotating shaft 32. The blades 33 are distributed alternately on the rotating shaft 32. This distribution pattern allows for better crushing of soil clods.

[0026] A support plate 4 is fixedly installed on the side wall of the bucket 2, and a motor 31 is fixedly installed on the support plate 4. The output end of the motor 31 is fixedly connected to the rotating shaft 32.

[0027] In this embodiment: First, when the bulldozer 1 uses the bucket 2 to push the soil, the motor 31 is turned on and put into operation. The motor 31 drives the rotating shaft 32 to rotate through the output end. The rotating shaft 32 drives several blades 33 to rotate. When the large clods of soil in the bucket 2 come into contact with the blades 33, the soil clods will be quickly broken into smaller soil particles. This achieves the effect of quickly breaking large clods of soil into smaller soil particles, making full use of the space of the bucket 2 and improving the bulldozing efficiency.

[0028] Example 2

[0029] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figures 3-5 A snap-fit ​​assembly 5 is provided on the rotating shaft 32;

[0030] The snap-fit ​​assembly 5 includes a sliding groove 52 formed on the rotating shaft 32 and a mounting groove 51 communicating with the side wall of the sliding groove 52. Figure 5 As can be seen, the bottom wall of the sliding groove 52 is lower than the bottom wall of the mounting groove 51, which facilitates the insertion of the trapezoidal block 53 into the snap-fit ​​groove 56. The mounting groove 51 is slidably provided with the trapezoidal block 53, and a spring 54 is fixedly connected between the trapezoidal block 53 and the mounting groove 51. The spring 54 allows the trapezoidal block 53 to be better inserted into the snap-fit ​​groove 56, making it difficult for the blade 33 to fall off. One end of the blade 33 is slidably provided in the sliding groove 52, and a snap-fit ​​groove 56 is provided on the side wall of one end of the blade 33.

[0031] The upper sidewall of the snap-fit ​​groove 56 is set with an inclined surface, and the trapezoidal block 53 is snapped into the snap-fit ​​groove 56. Through the cooperation of the two, the trapezoidal block 53 can be better snapped into the snap-fit ​​groove 56.

[0032] A limiting groove 55 is provided on the rotating shaft 32. The limiting groove 55 is connected to the mounting groove 51. A pulling column 57 is fixedly installed on the upper end of the trapezoidal block 53. The pulling column 57 is slidably arranged in the limiting groove 55.

[0033] A mounting frame 6 is fixedly installed on the rotating shaft 32. A magnetic block 8 is fixedly installed on the side wall of the mounting frame 6. A sealing plate 7 is hinged to the mounting frame 6. With the cooperation of the sealing plate 7 and the mounting frame 6, external soil is prevented from entering the limiting groove 55, which would affect the use of the pulling column 57 and the spring 54. The limiting groove 55 is located inside the mounting frame 6. The sealing plate 7 and the magnetic block 8 are magnetically attracted to each other. Figure 5 As can be seen, the horizontal position of the uppermost end of the magnetic block 8 is level with the upper horizontal position of the mounting frame 6, which facilitates the opening of the sealing plate 7. The sealing plate 7 can be limited by the setting of the magnetic block 8.

[0034] In this embodiment: when the blade 33 is damaged and needs to be replaced, first open the sealing plate 7 to separate the sealing plate 7 from the mounting frame 6 and the magnetic block 8. The operator can then pull the pulling column 57 to slide along the limiting groove 55 away from the sliding groove 52. At this time, the pulling column 57 drives the trapezoidal block 53 to slide. During the sliding process, the trapezoidal block 53 will compress the spring 54. When it is displaced to a suitable position, the trapezoidal block 53 will disengage from the limiting groove 55 on the blade 33. At this time, the blade 33 can be separated from the rotating shaft 32, thus realizing the disassembly of the blade 33.

[0035] When the blade 33 needs to be installed, during the process of inserting the blade 33 into the sliding groove 52, its end will press against the inclined surface of the trapezoidal block 53. During the pressing process, the trapezoidal block 53 will slide away from the blade 33. When the end of the blade 33 contacts the bottom wall of the sliding groove 52, the trapezoidal block 53 will be pushed into the snap-fit ​​groove 56 on the blade 33 by the elastic force of the spring 54, thus completing the installation of the blade 33.
