Description

Technical Field

[0001] This utility model relates to the field of material feeding technology, and in particular to a material feeding device for lime-soil compaction piles. Background Technology

[0002] Lime-soil compaction piles are an effective foundation treatment technology, primarily used to eliminate the collapsibility of collapsible soils and improve the bearing capacity of the foundation. The fill material for lime-soil compaction piles should be a mixture of lime and soil in an appropriate ratio. Before pile construction, holes need to be drilled in the soil foundation, and then the lime-soil mixture is compacted in layers. When constructing lime-soil compaction piles, it is necessary to determine the pile diameter, hammer weight and drop height, number of blows, and the amount of loose lime-soil in each layer within the borehole. Once the pile diameter, hammer weight and drop height, and number of blows are determined, the accuracy of the lime-soil mix ratio and the amount of loose lime-soil in each layer within the borehole become crucial factors affecting the effectiveness of the lime-soil compaction pile construction.

[0003] Currently, the backfilling of lime-soil compaction piles during pile formation is generally done by pushing the lime-soil in with a bulldozer. This method cannot accurately control the amount of loose fill in each layer; at the same time, the bulldozer may push soil and stones from the ground into the hole, affecting the lime-to-soil ratio. After pile formation, the lime-soil compaction pile's ability to eliminate soil collapsibility and improve the bearing capacity of the foundation will be affected.

[0004] Therefore, there is an urgent need to provide a material feeding device for lime-soil compaction piles, which, compared with existing technologies, controls the amount of loose lime-soil in layers and ensures accurate feeding into the borehole. Utility Model Content

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0022] like Figure 1 As shown, this utility model provides a material feeding device for compacted soil piles, including a frame 6, a hopper 2, wheels 1, a material blocking component, a weighing and feeding component, and a feeding component. The frame 6 includes a flat plate and a support component. The upper end of the flat plate is fixedly connected to the support component, and the upper end of the support component is provided with the hopper 2. Multiple wheels 1 are rotatably connected to the lower end of the flat plate. The lower end of the hopper 2 is provided with a discharge port, and the material blocking component is provided at the discharge port. The weighing and feeding component is provided on the upper wall of the flat plate, and the feeding component is provided at one end of the flat plate. The weighing and feeding component is positioned above the discharge port of the hopper 2 at one end and on the side of the other end.

[0023] like Figure 1 , Figure 2 As shown, the baffle assembly includes a baffle 21, a first rotating shaft 22, a hydraulic rod 23, and a first connecting shaft 24. The first rotating shaft 22 is fixedly connected to a set of opposite side walls of the hopper 2. The baffle 21 is connected to the first rotating shaft 22 and is rotatably connected to the hopper 2. When the baffle 21 is in a vertical position, it covers the discharge port. The hydraulic rod 23 is fixedly connected to the side wall of the baffle 21, and the first connecting shaft 24 is also fixedly connected to the side wall of the baffle 21. The output end of the hydraulic rod 23 is rotatably connected to the first connecting shaft 24. When the hydraulic rod 23 is fully extended, the baffle 21 is in a vertical position, covering the discharge port. When the hydraulic rod 23 retracts, it drives the baffle 21 to... Figure 2 Rotating counterclockwise as shown, the baffle 21 moves away from the discharge port, causing the ash and soil in the hopper 2 to fall onto the weighing and feeding assembly.

[0024] The weighing and feeding assembly includes a weighing conveyor belt 3 and a motor 31. The weighing conveyor belt is rotatably connected above the flat plate of the frame 6, and the motor 31 is located above the flat plate of the frame 6. The motor 31 provides power for the movement of the weighing conveyor belt. The weighing conveyor belt 3 achieves dynamic weighing through a built-in electronic scale or sensor. The structure of the weighing conveyor belt 3 is existing technology and will not be described in detail here. The weighing conveyor belt 3 is electrically connected to the control box 5 and transmits the obtained weighing signal to the control box 5. The layered loose filling amount of the lime-soil is set. When the weighing signal transmitted to the control box 5 reaches the layered loose filling amount of the lime-soil, the weighing conveyor belt 3 stops running. At this time, the baffle 21 closes and the discharge port stops discharging.

[0025] The feeding assembly includes a feeding hopper 4, a second rotating shaft 41, a direction control rod 42, and a second connecting shaft 43. Two second rotating shafts 41 are fixedly connected inside the flat plate of the frame 6, and the feeding hopper 4 is rotatably connected between the two second rotating shafts 41. The feeding hopper 4 has a feeding port at its lower end, which is located below the flat plate of the frame 6. The direction control rod 42 is rotatably connected to the lower part of the flat plate of the frame 6. The direction control rod 42 is a telescopic rod. The second connecting shaft 43 is fixedly connected to the side wall of the feeding hopper 4. One end of the direction control rod 42 is rotatably connected to the second connecting shaft 43. By adjusting the length of the direction control rod 42, the position of the feeding port at the lower end of the feeding hopper 4 can be adjusted so that the feeding port is aligned with the drill hole.

[0026] The flat section of the frame 6 is fixedly connected to the traction beam 7 at the end away from the feeding hopper 4. The traction beam 7 is used to connect the tractor vehicle.

[0027] The working principle of the lime-soil compaction pile feeding device provided by this utility model is as follows: The properly mixed lime-soil is loaded into the hopper 2 by a loader or other machinery; the traction beam 7 connects to the tractor, pulling the feeding device to the drilling position to be compacted; the direction control lever 42 at the feeding hopper 4 is adjusted so that the feeding port of the feeding hopper 4 is aligned with the drilling hole; the hydraulic rod 23 is retracted to open the baffle 21, and the weighing conveyor belt 3 starts running. The lime-soil falls from the hopper 2 onto the weighing conveyor belt 3, and then enters the feeding hopper 4 from the end of the weighing conveyor belt 3, accurately filling the drilling hole; the weighing conveyor belt 3 transmits the information of the amount of lime-soil conveyed to the control box 5. When the conveying amount reaches the layered loose filling amount of lime-soil, the weighing conveyor belt 3 stops running, and the baffle 21 closes, the hopper 2 stops discharging, completing one feeding operation; the above operation is repeated to feed multiple drilling holes; after the lime-soil in the hopper 2 is consumed, lime-soil is loaded into the hopper 2 again for the next cycle.

[0028] The feeding device of this invention can accurately measure the amount of material to be fed, allowing for precise addition of lime-soil into the boreholes, and it is highly mobile. By adjusting the direction of the feeding hopper 4, it ensures that the lime-soil is evenly filled into the boreholes without the introduction of other impurities, thus guaranteeing the quality of the backfill. The weighing conveyor belt 3 can precisely control the amount of loosely filled lime-soil in layers, further ensuring the effectiveness of the lime-soil compaction piles in treating collapsible soil foundations. The feeding device can move flexibly and quickly, and the large capacity of the hopper 2 can meet the needs of feeding multiple boreholes or feeding a single borehole multiple times, effectively improving the efficiency of pile formation.

[0029] This utility model relates to a material feeding device for compacted soil piles, which offers precise material feeding, accurate material quantity, high feeding efficiency, and flexible movement. It is suitable for eliminating the collapsibility of collapsible soils in dam foundations, roadbeds, and building foundations. The structure and components are simple.

[0030] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
