[0002] Buildings refer to material products piled up with heavy material materials and are one of the important material and cultural forms of human beings. Among them, ramming equipment is a construction machinery used for ramming ground operations.

[0003] For current ramming equipment, such as a highly practical ramming equipment for electric power construction disclosed in the Chinese patent publication number "CN210658308U", which rams the ground by pulling a striking block with a towing rope. However, after ramming the land for a long time, soil blocks and dust will adhere to the bottom surface, and the rammer head cannot be cleaned and maintained, and manual cleaning needs to be carried out separately, which is very inconvenient to use. Accordingly, this application proposes an efficient foundation pit ramming equipment for construction. Summary of the Utility Model

Chute grooves are opened on both sides of the fixed block. A cleaning mechanism for automatically and reciprocally cleaning the bottom surface of the equipment is arranged inside the chute grooves. The cleaning mechanism includes a reciprocating lead screw rotatably connected between the inner walls of one chute groove, and a slide bar fixedly connected between the inner walls of the other chute groove. Sliding blocks are slidably connected to the outer sides of the reciprocating lead screw and the slide bar. The sliding blocks are in threaded connection with the reciprocating lead screw. Fixed columns are fixedly connected to the outer sides of both sliding blocks. Rotating arms are rotatably connected to the outer sides of both fixed columns. Torsion springs are fixedly connected between both rotating arms and both fixed columns. A cleaning scraper is fixedly connected to the common bottom of both rotating arms. A pull rod is slidably connected inside one rotating arm close to the reciprocating lead screw. A plug pin is fixedly connected to one end of the pull rod close to the sliding block. A first spring is fixedly connected between the plug pin and the inner wall of the rotating arm. A plug pin hole is opened on the side of the sliding block close to the plug pin.

[0007] Preferably, a limiting mechanism for limiting the lifted cleaning scraper is arranged inside the fixed block close to the cleaning scraper. The limiting mechanism includes three guide rods fixedly connected inside the fixed block. A stop block is slidably connected to the common top of the three guide rods. Three second springs are fixedly connected between the stop block and the inner wall of the fixed block.

[0008] Preferably, a motor is fixedly connected to the top of the fixed block close to the reciprocating lead screw, and the driving end of the motor is interconnected with the reciprocating lead screw through a synchronous belt.

[0009] Preferably, a rammer is fixedly connected to the bottom of the fixed block, an accumulator is fixedly connected to the top of the outer frame, a hydraulic rod is fixedly connected inside the outer frame and at the bottom of the accumulator, and the bottom of the hydraulic rod is fixedly connected to a hammer body slidably connected to the outer frame.

[0011] Preferably, one end of the torsion spring is fixedly connected to the fixed column, and the other end of the torsion spring is fixedly connected to the inner wall of the rotating arm.

[0012] The utility model has the following beneficial effects:

[0013] 1. By arranging a cleaning mechanism, the motor can drive the synchronous belt to drive the reciprocating lead screw to rotate. At this time, the slider slides back and forth along the reciprocating lead screw, and the slider drives the rotating arm and the cleaning scraper at the bottom of the rotating arm to slide synchronously and reciprocally. Finally, the cleaning scraper continuously and reciprocally cleans and maintains the bottom surface of the rammer.

[0014] 2. By arranging a limiting mechanism, when the cleaning scraper rotates and lifts, the cleaning scraper presses the inclined surface on the stop block. Thus, the stop block slides downward along the guide rod to compress the second spring. When the cleaning scraper rotates to the rear of the stop block, the stop block is no longer pressed, and the second spring rebounds to push the stop block back to its initial position to block and limit the cleaning scraper.

The cleaning mechanism includes a reciprocating lead screw 4 rotatably connected between the inner walls of one chute 3, a slide bar 5 is fixedly connected between the inner walls of the other chute 3, sliders 6 are slidably connected to the outer sides of the reciprocating lead screw 4 and the slide bar 5, the sliders 6 are threadedly connected to the reciprocating lead screw 4, fixed columns 7 are fixedly connected to the outer sides of the two sliders 6, rotating arms 8 are rotatably connected to the outer sides of the two fixed columns 7, torsion springs 9 are fixedly connected between the two rotating arms 8 and the two fixed columns 7, and a cleaning scraper 10 is fixedly connected to the bottom of the two rotating arms 8. It should be noted that by arranging the reciprocating lead screw 4 and the slider 6, the rotation of the reciprocating lead screw 4 can drive the slider 6 to slide back and forth, and the slider 6 can drive the rotating arm 8 and the cleaning scraper 10 at its bottom to reciprocatingly clean along the bottom surface of the rammer 20.

[0024] A pull rod 11 is slidably connected inside one side of a rotating arm 8 close to the reciprocating lead screw 4, a pin 12 is fixedly connected to one end of the pull rod 11 close to the slider 6, a first spring 13 is fixedly connected between the pin 12 and the inner wall of the rotating arm 8, and a pin hole 14 is opened on one side of the slider 6 close to the pin 12. It should be noted that by arranging the pin 12 and the pin hole 14, the rotating arm 8 can be fixedly limited by inserting the pin 12 into the pin hole 14.

[0025] Inside the fixed block 2 near one side of the cleaning scraper 10, a limiting mechanism is provided for limiting the lifted cleaning scraper 10. The limiting mechanism includes three guide rods 15 fixedly connected inside the fixed block 2. The tops of the three guide rods 15 are commonly connected with a sliding block 16 in a sliding manner. Between the sliding block 16 and the inner wall of the fixed block 2, three second springs 17 are fixedly connected. It should be noted that by setting the sliding block 16 and the second springs 17, a return thrust can be given to the sliding block 16 through the second springs 17 to block and limit the retracted cleaning scraper 10.

[0026] At the top of the fixed block 2 near the reciprocating lead screw 4, a motor 18 is fixedly connected. Between the driving end of the motor 18 and the reciprocating lead screw 4, they are interconnected through a synchronous belt 19. It should be noted that by setting the motor 18 and the synchronous belt 19, the motor 18 can drive the synchronous belt 19 to synchronously drive the reciprocating lead screw 4 to rotate.

[0027] At the bottom of the fixed block 2, a rammer 20 is fixedly connected. At the top of the outer frame 1, an accumulator 21 is fixedly connected.

At this time, the slider 6 slides back and forth along the reciprocating lead screw 4. The slider 6 drives the rotating arm 8 and the cleaning scraper 10 at the bottom of the rotating arm to slide reciprocally synchronously, and finally enables the cleaning scraper 10 to continuously reciprocally clean and maintain the bottom surface of the rammer 20.
