Description

Technical Field

[0001] This utility model relates to the field of earthwork construction technology, specifically to a bulldozer shovel leveling device. Background Technology

[0002] Earthwork engineering is one of the major engineering projects in building construction. It is a general term for the excavation, transportation, filling, compaction, disposal, drainage, and earthwork support of soil. For example, when building a building, the soil for the foundation needs to be excavated first, which is earthwork excavation. In some road construction, the excavated soil is transported to the place where it needs to be raised, which involves earthwork transportation and filling.

[0003] In earthwork construction, the use of large machinery is extremely important. At the beginning of construction, it can level the site, smooth out uneven ground, and create favorable conditions for subsequent construction. It can also transport materials such as soil and gravel over short distances. On small construction sites, it can push the excavated soil to a designated location for stockpiling. However, during construction, when encountering uneven ground levels, bulldozers can currently only level the soil by adjusting the machine's position. This not only requires multiple adjustments to the machine's position but also demands a certain level of skill from the operator. Multiple adjustments also waste diesel fuel to some extent, resulting in significant economic losses. Furthermore, when there are specific requirements for the site leveling elevation, specialized surveyors are needed to measure the bulldozer elevation in real time.

[0004] Therefore, this utility model provides a bulldozer shovel leveling device to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a bulldozer shovel leveling device, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A bulldozer shovel horizontal adjustment device includes a body, a track rotatably connected to the bottom end of the body, a connecting plate fixedly connected to the end of the body, and an adjustment component provided on one side of the connecting plate;

In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0025] Reference Figures 1-6 This utility model provides two technical solutions:

[0026] Example 1:

[0027] A bulldozer shovel horizontal adjustment device includes a body 1, a track 101 rotatably connected to the bottom end of the body 1, a connecting plate 102 fixedly connected to the end of the body 1, and an adjustment component 2 provided on one side of the connecting plate 102.

[0028] The adjustment assembly 2 includes a pressure distribution box 201 fixedly connected to the outer wall of the machine body 1. A hydraulic main cylinder 202 is fixedly connected to the end of the connecting plate 102. A ball head 203 is fixedly connected to the end of the hydraulic main cylinder 202. An end plate 204 is rotatably sleeved on the outer wall of the ball head 203. A balance shaft 205 is fixedly connected inside the end plate 204. Rotating balls 206 are fixedly connected to both ends of the balance shaft 205. A support rod 207 is rotatably sleeved on the outer wall of the rotating balls 206. A lifting cylinder 208 is fixedly connected to the outer wall of the connecting plate 102. A damping ring 209 is fixedly connected to the output end of the lifting cylinder 208 and is fixedly sleeved on the outer wall of the support rod 207. A reinforcing rib 210 is fixedly connected to the outer wall of the support rod 207. A bucket 211 is fixedly connected to the inner wall of the reinforcing rib 210.

[0029] The end of the support rod 207 is fixedly connected to a balancing hydraulic rod 212. The input end of the balancing hydraulic rod 212 is fixedly sleeved with a hydraulic branch pipe 213, and the hydraulic branch pipe 213 is connected to the pressure distribution box 201. The end of the pressure distribution box 201 is fixedly sleeved with a fixing ring 214 on the outer wall of the hydraulic branch pipe 213.

[0030] Specifically, the tracks 101 below the body 1 allow for a wider range of bulldozer applications. The connecting plate 102 at the end of the body 1 strengthens the connection with the pressure distribution box 201, preventing swaying during bulldozing. The adjustment assembly 2 allows for leveling of the bucket 211 via external hydraulic pipes through the bulldozer's hydraulic system, facilitating easier pushing of the soil pile by the operator. The lifting cylinder 208 is adjusted via external hydraulic pipes, which in turn adjusts the support rod 207. Since the end of the support rod 207 is connected to the balance shaft 205 via a rotating ball 206, the connection between the balance shaft 205 and the end plate 204 is not affected. The bucket 211 is adjusted by the reinforcing ribs 210 on the outer wall of the support rod 207. Since a hydraulic master cylinder 202 is installed and its end is connected to the end plate 204 via a ball head 203, the end plate 204 will also rotate via the ball head 203 when the bucket 211 is adjusted, thus not affecting the operation of the hydraulic master cylinder 202. The hydraulic master cylinder 202 can easily push the bucket 211 to move longitudinally, making it easier to shovel the soil. When adjusting the horizontal height of the bucket 211, hydraulic oil flows from the hydraulic branch pipe 213 to the balance hydraulic rod 212 through the pressure distribution box 201. The balance rod inside the rod provides internal hydraulic lifting compensation for the support rod 207, which can greatly improve the accuracy of the horizontal adjustment.

[0031] Example 2:

[0032] Based on Example 1:

[0033] A hydraulic push rod 3 is fixedly connected to the end of the pressure distribution box 201. A fixing rod 301 is fixedly connected to the output end of the hydraulic push rod 3, and the fixing rod 301 is fixedly connected to the outer wall of the bucket 211.

[0034] A shock-absorbing box 302 is fixedly connected to the outer wall of the end plate 204. Multiple shock-absorbing springs 303 are fixedly connected to the inner wall of the shock-absorbing box 302. A shock-absorbing block 304 is fixedly connected to the end of the shock-absorbing spring 303, and the end of the shock-absorbing block 304 is fixedly connected to the bucket 211.

[0035] A prism 103 for calibrating the balance of the bucket 211 is fixedly connected to the top of the bucket 211, and a balancer 104 is fixedly connected to the outer wall of the prism 103.

[0036] A support frame 105 is fixedly connected to the top of the connecting plate 102. A rubber washer 106 is fixedly connected inside the support frame 105, and the rubber washer 106 is wrapped around the outer wall of the hydraulic push rod 3.

[0037] Specifically, the hydraulic push rod 3 at the end of the pressure distribution box 201 can be adjusted to change the position of the fixed rod 301 and the bucket 211, thereby adjusting the angle of the bucket 211 for better cutting of the soil. The shock absorption box 302 on the outer wall of the end plate 204 facilitates longitudinal shock absorption of the bucket 211 during bulldozing. Multiple shock absorption springs 303 prevent hard friction between the bucket 211 and the end plate 204 during operation, thus avoiding wear on the bulldozer. Excessive wear and tear can affect the service life of the machine. By using the support frame 105 on the connecting plate 102, the hydraulic push rod 3 can be supported and limited. The prism 103 on the side wall of the bucket 211 can be used to adjust the verticality of the bucket 211 with the operator's measuring instruments during relatively precise operation. The balancer 104 on the outer wall of the prism 103 can facilitate the operator to quickly adjust the horizontal state of the bucket 211, which is conducive to improving the construction efficiency of the bulldozer.
