DETAILED DESCRIPTION

[0027] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0028] like Figure 1 As shown, a hole-forming and lime-filling integrated machine for lime pile construction includes a crawler chassis 1, a lime hopper 2, a discharge port 3, a suspension 4, a hole-forming pile pipe 5 and a vertical hydraulic cylinder 6.

[0029] like Figure 1 As shown, the crawler chassis 1 is used for walking on the ground, and a cab 11 is provided at the front end for controlling the crawler chassis 1 to travel stably on the ground. The lime hopper 2 is provided on the crawler chassis 1 and is located behind the cab 11 for containing lime.

[0030] like Figure 1 , Figure 2 As shown, the discharge port 3 is arranged at the lower end of the lime hopper 2, and extends to the front of the crawler chassis 1 after passing under the cab 11. The opening end of the discharge port 3 faces downward, and is provided with an ash discharge nozzle 31, and an electromagnetic valve 32 is arranged inside the ash discharge nozzle 31.

[0031] like Figure 1 , Figure 3As shown, the suspension 4 is horizontally arranged at the front end of the crawler chassis 1, and the suspension 4 includes a support frame 41, a slide 42 and a horizontal hydraulic cylinder 43. The support frame 41 is arranged in front of the crawler chassis 1, the slide 42 is horizontally slidably connected to the support frame 41, and the horizontal hydraulic cylinder 43 is used to control the horizontal sliding of the slide 42.

[0032] like Figure 1 , Figure 3 As shown, the drilling pile pipe 5 is vertically slidably connected to the slide 42 and is used for drilling holes on the ground. The vertical hydraulic cylinder 6 is arranged on the slide 42 and is used to control the vertical sliding of the drilling pile pipe 5 for stable drilling on the ground.

[0033] like Figure 1 , Figure 3 As shown, both ends of the slide 42 are provided with end plates 44 distributed on the front and rear sides of the support frame 41, and a limit rod 45 is horizontally provided between the end plates 44 and penetrates the support frame 41. A scale 46 is provided on the limit rod 45, and a bolt 47 for contacting the inner wall of the support frame 41 is threadedly connected to the limit rod 45, and a row of screw holes 48 corresponding to the scale 46 and for the bolts 47 to be screwed in are provided on the limit rod 45.

[0034] When lime piles need to be constructed, the electromagnetic valve 32 in the ash discharge nozzle 31 is closed first, and then lime is added to the lime hopper 2, and the lime is automatically slid to the position of the discharge port 3. Then, according to the requirements of the drawing and the value of the scale 46, the bolts 47 are tightened in the corresponding screw holes 48, and the horizontal hydraulic cylinder 43 is used to control the sliding seat 42 to slide forward and backward, so that the bolts 47 are against the inner wall of the support frame 41, thereby adjusting the distance between the bored pile pipe 5 and the ash discharge nozzle 31, so that when drilling a new hole, the ash discharge nozzle 31 is located at the rear of the drilled hole.

[0035] Then, the vertical hydraulic cylinder 6 is controlled to drive the bored pile pipe 5 downward to make the bored pile pipe 5 cone into the soil, and then the vertical hydraulic cylinder 6 is controlled to drive the bored pile pipe 5 upward to return to the initial position, thereby completing the drilling operation.

[0036] Then the crawler chassis 1 is controlled to move forward a certain distance, which is the distance between the lime piles. At this time, the ash discharge nozzle 31 is aligned with the pile hole position that has been drilled on the ground, and then the solenoid valve 32 in the ash discharge nozzle 31 is opened to inject lime into the pile hole. After it is filled, the solenoid valve 32 is closed to complete the ash filling operation.

[0037] Then repeat the above steps again to complete the drilling of the pile hole of the next lime pile and the filling of lime, thereby completing the construction of rows of lime piles.

[0038] Therefore, by setting up a construction machinery that integrates hole drilling and mortar filling, continuous drilling and mortar filling of lime piles can be achieved, making the construction process more continuous and improving construction efficiency. At the same time, it can ensure the stable vertical movement of the bored pile pipe 5 and the quality of the hole drilling, and is used to achieve efficient, high-quality, and fully mechanized construction of large quantities of lime piles in rows, which greatly improves construction efficiency and reduces labor costs.

[0039] At the same time, by providing a bored pile pipe 5 with adjustable front and rear distances, the distance between the bored pile pipe 5 and the ash discharge nozzle 31 can be quickly adjusted, thereby achieving rapid and stable construction of lime piles with different distances, ensuring construction quality, and improving construction efficiency.

[0040] like Figure 1 , Figure 2 As shown, a cloth sleeve 33 is provided at the lower end of the ash discharge nozzle 31 , a counterweight ring 34 is provided at the lower end of the cloth sleeve 33 , and a driving member 35 for controlling the vertical movement of the counterweight ring 34 is provided on the ash discharge nozzle 31 .

[0041] like Figure 1 , Figure 2 As shown, the driving member 35 includes a driving frame 36 and an electric cylinder 37 . The driving frame 36 is distributed on both sides of the counterweight ring 34 and is vertically slidably connected to the outer wall of the ash discharge nozzle 31 . The electric cylinder 37 is used to control the vertical sliding of the driving frame 36 .

[0042] When lime needs to be injected into the pile hole, the electric cylinder 37 is used to control the driving frame 36 to move downward, and the driving frame 36 drives the counterweight ring 34 to move synchronously, and the cloth sleeve 33 is automatically unfolded. At this time, the cloth sleeve 33 surrounds the pile hole. Therefore, during the lime injection process, the lime is prevented from being blown away by the wind and diffused, thereby ensuring stable lime filling and reducing lime waste.

[0043] like Figure 1 , Figure 2 As shown, a pair of tie rods 7 are provided on the lower end surface of the front end of the suspension 4, and the pair of tie rods 7 are distributed on both sides of the bored pile pipe 5. A guide ring 71 for the bored pile pipe 5 to pass through is provided between the lower ends of the pair of tie rods 7, and a cleaning ring 72 that contacts the outer wall of the bored pile pipe 5 is provided at the lower end of the guide ring 71.

[0044] Therefore, by providing the guide ring 71 with a cleaning function, the stable vertical movement of the bored pile pipe 5 can be ensured when the bored pile pipe 5 slides vertically to ensure the construction quality, and the self-cleaning of the bored pile pipe 5 can be achieved to ensure the cleanliness of the bored pile pipe 5.

[0045] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
