Description

Technical Field

[0001] This utility model belongs to the field of construction engineering technology, and specifically relates to a soil collection and drying device for rotary drilling of pile foundations. Background Technology

[0002] During rotary drilling of foundation piles in building construction, to ensure smooth drilling, mud is typically injected into the pile hole simultaneously. This reduces drilling difficulty and prevents hole collapse and suspended drill cuttings. This results in the drilled soil having a high water content, exhibiting a silt-like or even fluid state. In current construction practices, the drilled soil is often unloaded directly onto the ground near the pile hole, temporarily stored, and then transported elsewhere, or used as backfill soil on-site. However, the high water content of the drilled soil makes it unsuitable for direct backfilling. Leakage during storage at the construction site or loading and transport can spread, negatively impacting the construction site and transport vehicles.

[0003] Currently, the existing solution to the problems of high moisture content and water seepage in rotary drilling soil is to set up a box next to the rotary drilling rig as a discharge bin to temporarily store the soil and prevent moisture from overflowing, while an excavator is placed nearby to assist in transporting the soil. Although this method can transport the soil in a timely manner and prevent moisture from seeping into the construction site, it still does not solve the problem of high moisture content in the soil itself, and the discharge bin cannot be quickly set up as the rotary drilling rig moves. Summary of the Invention

[0004] In order to overcome the defects of the existing technology, the purpose of this utility model is to provide a pile foundation rotary excavation soil collection and drying device that can quickly process rotary excavation soil and separate water and soil, so as to solve the problem of high water content and seepage of rotary excavation soil during construction.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pile foundation rotary excavation soil collection and drying device includes a self-propelled vehicle body 5, a discharge bin 1 installed at the rear of the self-propelled vehicle body 5, a drying device 3 and a water storage tank 4 installed on the self-propelled vehicle body 5, a conveying device 2 between the discharge bin 1 and the drying device 3, and the outlet of the drying device 3 is connected to the water storage tank 4.

[0007] The unloading bin 1 includes a housing 101, in which a screw feeder 102 is installed. The screw feeder 102 is powered by a drive motor 106. The drive motor 106 transmits power to the drive shaft 104 through a first chain drive 105. The drive shaft 104 transmits power to the screw feeder 102 through a second chain drive 107.

[0008] The conveying device 2 includes a conveyor belt 201, which is installed between the unloading bin 1 and the spin dryer 3 via a first support 202 and a second support 203 on the self-propelled vehicle body 5.

[0009] The spin-drying device 3 is powered by the second drive motor 303. A feeding bin 301 is installed on the top of the spin-drying device 3. A high-speed rotating distribution plate 305 is installed inside the outer shell 307 of the lower cavity of the feeding bin 301. A filter screen 306 is installed around the distribution plate 305. A rotating blade 302 is installed inside the filter screen 306. The discharge port 304 is located below the rotating blade 302. A discharge baffle 309 is installed below the discharge port 304. A water outlet 308 is installed on the outer shell 307 and is connected to the water storage tank 4.

[0010] The water storage tank 4 is equipped with a valve 401.

[0011] The unloading bin 1 is installed on the lifting base 108 at the rear of the self-propelled vehicle body 5.

[0012] The drive shaft 104 is installed in the dust cover 103 above the housing 101.

[0013] Compared with the prior art, the present invention has the following technical effects:

[0014] (1) This utility model addresses the problem that the soil from rotary excavation of pile foundations has a high water content and is not easy to backfill or transport directly. It adopts a drying treatment method to pre-treat the soil from rotary excavation of pile foundations, which facilitates transportation or backfilling.

[0015] (2) The unloading bin 1 of this utility model allows the rotary drilling rig to unload directly in the storage bin 1, effectively preventing the overflow of moisture from the accumulated rotary drilling soil.

[0016] (3) The unloading bin 1 of this utility model is equipped with a screw feeder 102, which, together with the conveying device 2, can quickly transport the rotary excavated soil to the drying equipment.

[0017] (4) The unloading bin 1 designed in this utility model is installed on the lifting base 108. When working, the lifting base is lowered to the ground to avoid the additional load affecting the vehicle body. When not working, the lifting base 108 is raised and the unloading bin is raised synchronously, which makes it convenient for the whole machine to move with the rotary drilling rig or be transferred to other working faces.

[0018] (5) The screw feeder 102 of this utility model is equipped with a dust cover, which can effectively prevent dust or rotary excavation soil at the construction site from interfering with the transmission device.

[0019] (6) The centrifugal drying device 3 of this utility model can quickly and effectively separate the moisture in the rotary excavated soil through centrifugal force, greatly reducing the moisture content of the rotary excavated soil and making the rotary excavated soil easier to process later.

[0020] (7) The unloading bin 1, conveying device 2 and drying device 3 of the rotary drilling soil collection of this utility model are all installed on the self-propelled vehicle body 5. The structure is reasonably arranged and the function is smooth. It can make the rotary drilling soil collection and drying equipment move with the rotary drilling rig. The equipment is easy to transfer and convenient to use.

[0021] In summary, this utility model has the ability to efficiently process rotary excavated soil and can quickly achieve soil-water separation, thereby effectively solving the problem of excessive moisture content in rotary excavated soil during construction, which leads to the spread of seepage.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] Reference Figure 1 A pile foundation rotary excavation soil collection and drying device includes a self-propelled vehicle body 5, a discharge bin 1 installed at the rear of the self-propelled vehicle body 5, a drying device 3 and a water storage tank 4 installed on the self-propelled vehicle body 5, a conveying device 2 between the discharge bin 1 and the drying device 3, and the outlet of the drying device 3 is connected to the water storage tank 4.

[0028] Reference Figure 2The unloading bin 1 is installed on a lifting base 108 at the rear of the self-propelled vehicle body 5. The lifting base 108 can raise or lower the unloading bin 1. Alternatively, the unloading bin 1 can be installed at the middle of the rear of the self-propelled vehicle body 5. When the rotary drilling soil collection and drying equipment for pile foundations is in operation, the lifting base 108 is lowered to the ground to avoid adding extra load to the equipment when the unloading bin 1 is suspended, thus preventing adverse effects on the overall equipment. When not in operation, the lifting base 108 is raised, allowing the unloading bin 1 to leave the ground and facilitating the transfer of the self-propelled vehicle body 5 to other locations. The unloading bin 1 includes a housing 101. During the rotary drilling of the pile foundation, the rotary drilling rig directly unloads the rotary drilling soil into the housing 101, preventing water seepage when the rotary drilling soil accumulates. A screw feeder 102 is installed in the housing 101 to transport the rotary drilling soil to the conveying device 2. The screw feeder 102 is powered by a drive motor 106. The drive motor 106 transmits power to the drive shaft 104 through a first chain drive 105. The drive shaft 104 transmits power to the screw feeder 102 through a second chain drive 107. The drive shaft 104 is installed in a dust cover 103 above the housing 101 to avoid dust and splashing during the unloading of rotary excavated soil.

[0029] Reference Figure 1 The conveying device 2 includes a conveyor belt 201, which can transport the rotary excavated soil conveyed by the screw feeder 102 to the drying device 3. The conveyor belt 201 is installed between the unloading bin 1 and the drying device 3 via a first support 202 and a second support 203 on the self-propelled vehicle body 5.

[0030] Reference Figure 3 The spin-drying device 3 is powered by a second drive motor 303. A feed hopper 301 is installed on the top of the spin-drying device 3. Rotary excavated soil, conveyed by the conveying device 2, falls into the feed hopper 301 and is introduced into the spin-drying device 3. A high-speed rotating distribution disc 305 is installed inside the outer shell 307 of the lower cavity of the feed hopper 301. Filter screens 306 are installed around the distribution disc 305. When the rotary excavated soil falls onto the high-speed rotating distribution disc 305, it is thrown onto the filter screens 306 by centrifugal force, thus filtering the moisture in the rotary excavated soil between the filter screens 306 and the outer shell 307 of the lower cavity. Rotating blades 302 are installed inside the filter screens 306, and an outlet 304 is located below the rotating blades 302. The spun-dryed soil is scraped off the filter screens 306 and conveyed to the outlet 304 for discharge. A discharge baffle 309 is provided below the discharge port 304, which can guide the spun-dry rotary excavated soil to one side of the self-propelled vehicle body 5 for transfer or on-site backfilling. A water outlet 308 is provided on the outer shell 307, which is connected to the water storage tank 4. The water outlet 308 guides the filtrate generated by spun-drying to the water storage tank 4.

[0031] The water storage tank 4 is equipped with a valve 401, which allows the filtrate to be discharged to a suitable location. The water storage tank 4 is installed on the self-propelled vehicle body 5 and can temporarily store the filtrate produced by spin-drying.

[0032] The working principle of this utility model is as follows: When not in operation, the lifting base 108 is raised, so that the unloading bin 1 is off the ground, making it convenient for the self-propelled vehicle body 5 to be transferred to a suitable position. When the rotary excavated soil is collected, the lifting base 108 is lowered to the ground, and the rotary excavated soil is transported into the unloading bin 1. The screw feeder 102 installed in the box 101 transports the rotary excavated soil to the conveying device 2. The conveying device 2 then feeds the dredged soil into the spin-drying device 3. The dredged soil conveyed by the conveying device 2 falls into the feed hopper 301 and is introduced into the spin-drying device 3. The dredged soil falls onto the high-speed rotating distribution plate 305 and is thrown onto the filter screen 306 by centrifugal force. Rotating blades 302 are provided on the inner side of the filter screen 306 to scrape the dredged soil off the filter screen 306 and convey it to the discharge port 304 for discharge. A discharge baffle 309 is provided below the discharge port 304 to guide the dredged soil to one side of the self-propelled vehicle body 5 for transfer or on-site backfilling. A water outlet 308 is provided on the outer shell 307 and is connected to the water storage tank 4 to guide the filtrate produced by spin-drying to the water storage tank 4. The water storage tank 4 is provided with a valve 401 to discharge the filtrate to a suitable place. The water storage tank 4 is installed on the self-propelled vehicle body 5 and can temporarily store the filtrate produced by spin-drying.

[0033] The unloading bin 1, conveying device 2, drying device 3, and water storage tank 4 are all mounted on the self-propelled vehicle body 5, with a reasonable layout and smooth operation. The self-propelled vehicle body 5 can follow the rotary drilling rig between different pile foundation locations, and can also move to the wastewater treatment location to unload the filtrate, solving the problems of fixed unloading bins being unable to move and internal moisture accumulation.
