Description

Technical Field

[0001] This application relates to the field of foundation pit technology, and in particular to a foundation pit cleaning and leveling device. Background Technology

[0002] During the earthwork construction phase, if mechanical excavation is used, to prevent disturbance to the original soil structure, a minimum of 200-300mm of soil should be manually removed according to relevant specifications. Relying entirely on manual trench cleaning increases costs and cannot meet construction schedules, especially in areas with hard soil, where manual trench cleaning becomes even more difficult.

[0003] A search revealed a Chinese patent publication number CN216865316U, which discloses a pit cleaning and leveling device, comprising a bucket body. Multiple bucket teeth are equidistantly fixedly installed on the left bottom end of the bucket body. Protective connecting sleeves are detachably fixedly fitted onto the bucket teeth, and extended teeth are detachably fixedly fitted onto the protective connecting sleeves. An installation groove is provided at the lower end of the protective connecting sleeve, and an installation screw passes through the lower end of each extended tooth. An installation rod is fixedly installed at the upper end of the installation screw, and a top head is fixedly installed at the upper end of the installation rod. The bottom of the installation screw is detachably fixedly connected to the lower end of the extended tooth via a locking nut. Four protruding side blocks are symmetrically fixedly installed at both ends of the installation rod, and a stop plate is fitted abutted to the upper end of each protruding side block. An installation abutment is fixedly installed at the end of the stop plate away from the installation rod.

[0004] The pit cleaning and leveling device in the above patent has the following shortcomings: The above patent uses the cooperation between the mounting bolt and the mounting rod between the bucket teeth and the reinforcing teeth to make the connection and fixation. However, since the locking nut protrudes on the surface of the extended teeth, it is severely worn during use. Long-term wear can easily lead to the extended teeth being unable to be disassembled. Utility Model Content

[0005] To address the problem of severe wear on the locking nut of the extended teeth, which makes the extended teeth difficult to disassemble, this application provides a pit cleaning and leveling device.

[0006] This application provides a pit clearing and leveling device, including a bucket body. A plurality of bucket teeth are fixedly connected to one inner wall of the bucket body at equal intervals. An elongated tooth is sleeved on the outer wall of the bucket teeth. A groove is opened on one outer wall of the bucket teeth, and the same screw is rotatably connected to the inner walls of both sides of the groove. A nut is screwed to the outer wall of the screw. An opening is opened on both inner walls of the groove. A limit block is rotatably connected to the inner wall of both openings. A connecting plate is rotatably connected to the outer wall of the nut. One end of the two connecting plates is rotatably connected to the two limit blocks respectively. A rectangular groove is opened on one outer wall of the elongated tooth, and a limit groove is opened on the inner walls of both sides of the rectangular groove.

[0007] With the above structure, two adjustable limit blocks are set in the bucket teeth. The limit blocks make it easy to fix the extended teeth on the outer wall of the bucket teeth. The screw makes it easy to drive the nut to move, thus making it easy to directly drive the two limit blocks to rotate.

[0008] The specifications of the limiting groove match the specifications of the limiting block, and the specifications of the rectangular groove match the specifications of the bucket teeth.

[0009] With the above structure, the limiting block is inserted into the limiting groove, which facilitates the fixing of the extended teeth.

[0010] The inner wall of the rectangular groove is slidably connected to a sliding seat, and multiple springs are fixedly connected between the sliding seat and the inner wall of the rectangular groove.

[0011] With the above structure, the spring provides convenient auxiliary support for the sliding seat.

[0012] The inner wall of the bucket tooth has a cavity, and the two inner walls of the cavity are rotatably connected to the same worm gear.

[0013] The inner walls on both sides of the cavity are rotatably connected to the same worm gear, and the worm gear and the worm wheel mesh with each other.

[0014] With the above structure, the rotation of the worm gear directly drives the rotation of the worm wheel.

[0015] One end of the worm gear drive shaft is fixedly connected to the screw, and the worm gear and the screw rotate synchronously.

[0016] The bottom outer wall of the bucket tooth is provided with a circular groove, and the inner wall of the circular groove is rotatably connected to a rotating head, the bottom outer wall of the rotating head is provided with a ridge groove.

[0017] With the above structure, a hexagonal wrench can be inserted into the groove to facilitate manual rotation of the rotating head.

[0018] One end of the rotating head drive shaft is fixedly connected to the worm gear.

[0019] With the above structure, the rotating head can easily drive the worm gear to rotate.

[0020] In summary, the beneficial effects of this application are as follows: This application incorporates extended teeth on the bucket teeth, which facilitates leveling of the pit by the bucket body. Additionally, two adjustable limit blocks are installed on the bucket teeth. When these limit blocks rotate and insert into the limit grooves, the extended teeth are easily fixed to the bucket teeth. The two limit blocks are adjusted by a screw, improving the stability of the extended teeth. Furthermore, the rotating head is embedded in the bucket teeth, effectively reducing wear on the rotating head and facilitating quick assembly and disassembly of the extended teeth.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] Please see Figure 1-3 A pit clearing and leveling device includes a bucket body 1. Multiple equally spaced bucket teeth 2 are fixedly connected to the inner wall of one side of the bucket body 1. Extended teeth 3 are sleeved on the outer wall of the bucket teeth 2. A groove is opened on one side of the outer wall of the bucket teeth 2, and the same screw 10 is rotatably connected to the inner walls of both sides of the groove. A nut 9 is screwed to the outer wall of the screw 10. An opening 6 is opened on both sides of the inner wall of the groove. A limit block 7 is rotatably connected to the inner wall of both openings 6. A connecting plate 8 is rotatably connected to the outer wall of both nuts 9. One end of the two connecting plates 8 is rotatably connected to the two limit blocks 7 respectively. A rectangular groove is opened on one side of the outer wall of the extended teeth 3, and a limit groove 13 is opened on the inner walls of both sides of the rectangular groove.

[0025] In use, two adjustable limit blocks 7 are set in the bucket teeth 2. The limit blocks 7 make it easy to fix the extended teeth 3 on the outer wall of the bucket teeth 2. The screw 10 makes it easy to drive the nut 9 to move, thus making it easy to directly drive the two limit blocks 7 to rotate.

[0026] Reference Figure 2-4 The specifications of the limiting groove 13 match the specifications of the limiting block 7, and the specifications of the rectangular groove match the specifications of the bucket tooth 2. The limiting block 7 is inserted into the limiting groove 13, which facilitates the fixing of the extended tooth 3.

[0027] Reference Figure 4 A sliding seat 12 is slidably connected to the inner wall of the rectangular groove, and multiple springs 11 are fixedly connected between the sliding seat 12 and the inner wall of the rectangular groove. The springs 11 are designed to provide auxiliary support for the sliding seat 12.

[0028] Reference Figure 5The inner wall of the bucket tooth 2 has a cavity, and the two inner walls of the cavity are rotatably connected to the same worm gear 14.

[0029] Reference Figure 5 The inner walls on both sides of the cavity are rotatably connected to the same worm 15, and the worm 15 and the worm wheel 14 mesh with each other. When the worm 15 rotates, it directly drives the worm wheel 14 to rotate.

[0030] Reference Figure 5 One end of the worm gear 14 drive shaft is fixedly connected to the screw 10, and the worm gear 14 and the screw 10 rotate synchronously.

[0031] Reference Figure 3 The bottom outer wall of the bucket tooth 2 has a circular groove, and the inner wall of the circular groove is rotatably connected to the rotating head 4. The bottom outer wall of the rotating head 4 has a prismatic groove, and a hexagonal wrench is inserted into the prismatic groove to facilitate manual rotation of the rotating head 4.

[0032] Reference Figure 5 One end of the drive shaft of the rotating head 4 is fixedly connected to the worm gear 15, so that the rotating head 4 can easily drive the worm gear 15 to rotate when it rotates.

[0033] The implementation principle of this application is as follows: When it is necessary to install the extended tooth 3 onto the bucket tooth 2, first, the extended tooth 3 is sleeved on the outer wall of the bucket tooth 2. Then, the extended tooth 3 is pushed to make the bucket tooth 2 push the sliding seat 12 to compress the spring 11. Then, the hex wrench is inserted into the groove 5 on the rotating head 4. The wrench is rotated to drive the rotating head 4 to rotate, which in turn drives the worm 15 to rotate. When the worm 15 rotates, it directly drives the worm wheel 14 to rotate. When the worm wheel 14 rotates, it drives the screw 10 to rotate. When the screw 10 rotates, it directly drives the nut 9 to move. When the nut 9 moves towards the worm wheel 14, it directly pulls the limiting block 7 to rotate through the connecting plate 8. When the limiting block 7 rotates, one end of it is directly inserted into the limiting groove 13. The setting of the limiting block 7 makes it convenient to fix the extended tooth 3 onto the bucket tooth 2.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
