AI Technical Summary
During the excavation of clay by existing bulldozers, the bucket is easily stuck by clay, resulting in a decrease in the efficiency of bulldozing. The existing technology uses wire rope to cut clay, but the clay is strongly clay, resulting in the clay still stuck after cutting and cannot be effectively cleaned.
A civil engineering foundation pit excavation equipment is designed, using two sets of driving parts and wire ropes to cooperate. Through the reciprocating motor and slider transmission, the wire rope is driven to move on the soil surface of the bucket, and vibrating parts are set on the bucket to utilize vibration force. Make the clay effectively detach during cutting.
Effectively cutting the clay on the bucket improves the operating efficiency of the bulldozer, ensures the cleanliness of the inner wall of the bucket, and avoids the need for manual cleaning.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of civil engineering equipment, in particular to a foundation pit excavation device for civil engineering. Background Art
[0002] A bulldozer is an engineering vehicle with a large metal bulldozer blade installed in the front. When in use, the bulldozer blade is lowered to shovel and push mud, sand and stones forward. The position and angle of the bulldozer blade can be adjusted. The bulldozer can complete the work of digging, transporting and unloading soil alone. It has the characteristics of flexible operation, convenient rotation, small required working surface and fast driving speed. It is mainly suitable for shallow excavation and short transportation of Class I to Class III soil, such as site cleaning or leveling, excavation of shallow foundation pits and backfilling, and construction of low-height roadbeds. However, since the bulldozer bucket is easily stuck to the surface by clay during operation, affecting the bulldozing efficiency of the bulldozer bucket, in this case, only manual help can be used to clean the clay for the bulldozer bucket, which seriously affects the operation of the bulldozer.
[0003] In the published Chinese patent application, publication number: CN213625763U, patent name: A bulldozer bucket, although, by using a steel wire rope to move and cut the clay, the setting of the support column enables the steel wire rope fixing head to push the steel wire rope to remain attached to the inner wall of the bucket, maintaining the effect of cleaning the inner wall of the bucket. Since the existing technology uses a steel wire rope to cut the clay, the steel wire rope has a small cut and the clay is highly sticky, so after the steel wire rope cuts the clay, the clay continues to adhere to the bucket after passing over the steel wire rope, resulting in the steel wire rope being unable to effectively cut the clay on the bucket.

[0029] See also Figure 1 to Figure 2 The utility model provides a technical solution: a foundation pit excavation equipment for civil engineering, including a bulldozer body 1, a bucket 2 is installed on the driving arm end of the bulldozer body 1 through a bayonet 4, and a mud removal assembly is arranged on the bucket 2, and the mud removal assembly includes two groups of driving parts and a steel wire rope 5, the two groups of driving parts are slidably arranged on both sides of the bucket 2, the two groups of driving parts are respectively fixedly connected to the two ends of the steel wire rope 5, and the two groups of driving parts synchronously pull the steel wire rope 5 to move on the shoveling surface of the bucket 2. The driving part includes a reciprocating motor 11 and a slider 7, the reciprocating motor 11 is transmission-connected to the slider 7, and the slider 7 is slidably connected to the bucket 2. The end of the slider 7 close to the shoveling surface of the bucket 2 is fixedly connected to the steel wire rope 5. A vibrating part is arranged on the bucket 2.
[0030] Among them, the steel wire rope 5 is synchronously driven by two sets of driving parts to move on the shoveling surface of the bucket 2, and the moving steel wire rope 5 cuts the clay on the shoveling surface of the bucket 2. The vibrating part is used to provide a vibration source for the bucket 2, so that when the bucket 2 uses the steel wire rope 5 to cut the clay, a vibration force is applied to the clay, so that the clay is effectively separated from the bucket 2 under the conditions of cutting and vibration, thereby achieving the purpose of effectively cutting off the clay on the bucket 2.
[0031] The vibrating member includes a first vibrating member, which is mounted on a side wall of the bucket 2 near the bayonet 4. The first vibrating member is a vibration motor 3. The vibration motor 3 is used to generate vibration and enable the bucket 2 to vibrate as a whole.
[0032] The reciprocating motor 11 is used to drive the slider 7 to slide. During the sliding of the slider 7, the wire rope 5 is pulled to move on the shoveling surface of the bucket 2. During the displacement of the wire rope 5 on the shoveling surface of the bucket 2, the clay on the soil production surface of the bucket 2 can be effectively cut off.
