Description

Technical Field

[0001] This invention relates to the field of mixing drill bits, and more particularly to a mixing pile drill bit for aeolian sand geology with a lubrication structure. Background Technology

[0002] When constructing buildings on foundations, piles need to be driven into the foundation. Cement mixing piles are a commonly used device for soft soil treatment in foundation engineering construction. Cement is used as the main solidifying agent. The cement is sprayed into the soil and thoroughly mixed using mixing piles, causing a series of physical and chemical reactions between the cement and the soil. The soft soil hardens to provide the strength of the foundation. However, the soil structure inside the foundation is diverse. When rock layers appear in the soil structure, the hardness and frictional resistance of the soil make it difficult for ordinary drill bits to drill effectively, resulting in low efficiency.

[0003] In the existing technology, during the use of mixing drill bits, due to certain geological specialties, the soil is hard, making it difficult for the mixing drill bit to penetrate. After prolonged use, the inside of the mixing drill bit also needs to be cleaned, otherwise impurities may accumulate inside the drill bit, affecting its use and resulting in low work efficiency. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of difficulty in drilling into hard soil and difficulty in cleaning the inside of the device when using mixing drill bits in the prior art. The invention proposes a mixing pile drill bit for aeolian sand geology with a lubricating structure. The cleaning mechanism and the squeezing mechanism are designed so that when the operator wants to clean the inside of the device, the squeezing device is added inside the device. When the operator operates the drive mechanism to drive the cleaning mechanism, the squeezing block is moved downward and pushes outward when it touches the top rod, squeezing out the cleaning sponge and water in the first mounting frame, thereby achieving the effect of wetting the soil and improving work efficiency.

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

[0006] A drilling bit for aeolian sand mixing piles with a lubricating structure includes a housing and a mixing drill bit. The housing has an installation groove and a connecting groove. A water outlet mechanism is provided in the connecting groove. A placement frame is fixedly installed inside the housing. A driving mechanism is provided in the installation groove, with its end extending into the placement frame. Sliding grooves are provided on opposite sidewalls of the placement frame, and a top-opening mechanism is provided on each of the two sliding grooves. The housing contains two first installation frames and two second installation frames. A cleaning mechanism is provided in each of the two first installation frames, with the cleaning ends of both cleaning mechanisms abutting against the inner sidewall of the housing. A squeezing mechanism is provided in each of the two second installation frames, with the ends of both cleaning mechanisms extending into the opposite second installation frames and fixedly connected to the sidewall of the squeezing mechanism.

[0007] Preferably, the water outlet mechanism includes a water outlet pipe fixedly installed in the connecting groove, and a water injection plate is fixedly connected to the side wall of the water outlet pipe, with multiple water injection ports opened on the water injection plate.

[0008] Preferably, the drive mechanism includes a motor fixedly installed at the top of the mounting groove, the output shaft of the motor extending into the placement frame and fixedly connected to a threaded rod, a mounting plate being threadedly connected to the threaded rod, the mounting plate being slidably connected to the slide groove, and the mounting plate being fixedly connected to the side wall of the second mounting frame.

[0009] Preferably, the opening mechanism includes a mounting rod fixedly installed in the slide groove, the end of which extends into the housing and is fixedly connected to a top rod.

[0010] Preferably, the cleaning mechanism includes a connecting rod slidably connected within a first mounting frame, one end of which is fixedly connected to a squeezing plate, and a cleaning sponge is fixedly connected to the side wall of the first mounting frame, the cleaning sponge abutting against the inner side wall of the housing.

[0011] Preferably, the extrusion mechanism includes an extrusion block slidably connected within the second mounting frame, the other end of the connecting rod extending into the second mounting frame and fixedly connected to the side wall of the extrusion block, a spring fixedly connected between the side wall of the extrusion block away from the connecting rod and the inner side wall of the second mounting frame, and a communication opening provided at the bottom of the second mounting frame.

[0012] Compared with the prior art, the beneficial effects of this invention are as follows:

[0013] 1. By setting up a cleaning mechanism, the cleaning mechanism can be automatically driven to clean hard-to-clean areas inside the device when the staff operates the drive mechanism.

[0014] 2. By setting up the squeezing mechanism, the operator can drive the squeezing block downward while operating the drive mechanism to drive the cleaning mechanism, so that it touches the top rod and pushes it outward, squeezing out the cleaning sponge and the water in the first mounting frame, and at the same time achieving the effect of wetting the soil.

[0015] In summary, the present invention has a reasonable structural design. By setting up a cleaning mechanism and a squeezing mechanism, it can automatically drive the cleaning mechanism to clean hard-to-clean areas inside the device when the operator operates the drive mechanism. At the same time, the squeezing device allows the operator to move the squeezing block downwards while operating the drive mechanism to drive the cleaning mechanism, so that it touches the top rod and pushes it outwards, squeezing out the water from the cleaning sponge and achieving the effect of wetting the soil.

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Reference Figure 1-3 A drilling bit for aeolian sand mixing piles with a lubricating structure includes a housing 1 and a mixing drill bit 2. The housing 1 has an installation groove 3 and a connecting groove 17. The connecting groove 17 has a water outlet mechanism. The water outlet mechanism includes a water outlet pipe 18 fixedly installed in the connecting groove 17. A water injection plate 19 is fixedly connected to the side wall of the water outlet pipe 18. The water injection plate 19 has multiple water injection ports.

[0022] A placement frame 7 is fixedly installed inside the housing 1. A drive mechanism is provided in the mounting groove 3. The end of the drive mechanism extends into the placement frame 7. The drive mechanism includes a motor 4 fixedly installed at the top of the mounting groove 3. The end of the output shaft of the motor 4 extends into the placement frame 7 and is fixedly connected to a threaded rod 5. A mounting plate 6 is threadedly connected to the threaded rod 5. The mounting plate 6 is slidably connected to the slide groove. The mounting plate 6 is fixedly connected to the side wall of the second mounting frame 8. Through the setting of the drive mechanism, the squeezing mechanism fixedly connected to the drive mechanism and the cleaning mechanism fixedly connected by the connecting rod 11 can be driven to move downward.

[0023] The opposite side walls of the placement frame 7 are provided with sliding grooves, and the upper part of the two sliding grooves is provided with a top opening mechanism. The top opening mechanism includes a mounting rod 15 fixedly installed in the sliding groove. The end of the mounting rod 15 extends into the housing 1 and is fixedly connected to a top rod 16. With the setting of the top opening mechanism, when the first mounting frame 12 and the second mounting frame 8 are moved to a certain position, the squeezing block 9 in the second mounting frame 8 is squeezed, and the water in the cleaning sponge 13 is squeezed out through the connecting rod 11.

[0024] The housing 1 is provided with two first mounting frames 12 and a second mounting frame 8. Each of the two first mounting frames 12 is provided with a cleaning mechanism. The cleaning ends of the two cleaning mechanisms abut against the inner sidewall of the housing 1. The cleaning mechanism includes a connecting rod 11 slidably connected in the first mounting frame 12. One end of the connecting rod 11 is fixedly connected to a squeezing plate 14. A cleaning sponge 13 is fixedly connected to the sidewall of the first mounting frame 12. The cleaning sponge 13 abuts against the inner sidewall of the housing 1. By setting up the cleaning mechanism, the cleaning mechanism can be automatically driven to clean the hard-to-clean areas inside the device when the operator operates the drive mechanism.

[0025] Each of the two second mounting frames 8 is equipped with a squeezing mechanism. The ends of the two cleaning mechanisms extend into the opposite second mounting frames 8 and are fixedly connected to the side wall of the squeezing mechanism. The squeezing mechanism includes a squeezing block 9 slidably connected in the second mounting frame 8. The other end of the connecting rod 11 extends into the second mounting frame 8 and is fixedly connected to the side wall of the squeezing block 9. A spring 10 is fixedly connected between the side wall of the squeezing block 9 away from the connecting rod 11 and the inner side wall of the second mounting frame 8. A communication port is opened at the bottom of the second mounting frame 8.

[0026] The functional principle of this invention can be explained through the following operational methods:

[0027] In this invention, when workers need to moisten hard soil, they fill the first mounting frame 12 with water through the main water pipe. The water in the first mounting frame 12 permeates into the cleaning sponge 13. At this time, the workers start the motor 4. The start of the motor 4 drives the threaded rod 5 to rotate. The threaded rod 5 drives the mounting plate 6, which is slidably connected to the slide groove, to move downward. The mounting plate 6 drives the second mounting frame 8, connected by the connecting rod 11, to move the first mounting frame 12 downward together, thereby driving the cleaning sponge 13 to clean the inner wall of the housing 1. When the first mounting frame 12 and the second mounting frame 8 move downward together, the cleaning sponge 13 cleans the inner wall of the housing 1. When the displacement reaches a certain position, the squeezing block 9 in the second mounting frame 8 is squeezed outward by the top rod 16. The displacement of the squeezing block 9 drives the connecting rod 11 to move outward, and the connecting rod 11 drives the squeezing plate 14 to move outward. The squeezing plate 14 squeezes the cleaning sponge 13, squeezing out the water in the cleaning sponge 13, which enters the water outlet pipe 18 through the water injection plate 19 and flows into the soil that needs to be moistened. After moistening is completed, the operator controls the threaded rod 5 to reset. The squeezing block 9 is also reset by the tension of the spring 10 after leaving the squeezing of the top rod 16. When moistening is needed, the threaded rod 5 can be started to repeat the above operation.

[0028] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
