Description

Technical Field

[0001] This utility model belongs to the field of anchor drilling machines, and specifically relates to a spiral anchor drilling machine with self-cleaning function. Background Technology

[0002] A auger anchor drill is a specialized piece of equipment used in foundation and underground engineering construction. It is primarily used for drilling and installing ground anchors, anchor bolts, and other support structures. Through the rotation of an auger bit, it effectively drills holes in soil or rock and implants anchoring material into the holes to enhance the soil's bearing capacity and stability.

[0003] Currently, after drilling, the drill bit of the rotary anchor drill carries the soil generated during drilling. It is lifted out of the hole and then thrown out by rotation. However, this centrifugal throwing method cannot completely remove the soil adhering to the surface of the auger drill bit. After long-term use, the soil will become thicker and thicker, which will affect the observation of the workers during drilling. Therefore, manual cleaning is required for reuse. Utility Model Content

[0004] To address the above deficiencies, this utility model provides a spiral anchor drilling machine with a self-cleaning function, including an anchor drilling rig, a support frame installed on the head of the anchor drilling rig, and a drill bit assembly installed on the head of the anchor drilling rig. The drill bit assembly includes an adjusting arm, a drive mechanism, a rotating shaft, a drill rod, and a drill bit. A stabilizing seat is installed on the positioning beam at the support frame, and a cleaning chamber is installed at the bottom of the stabilizing seat. The cleaning chamber is penetrated by the drill rod, and an external threaded tube is fixedly sleeved on the outer surface of the drill rod.

[0005] The cleaning chamber is fixed to a top seat and a base by bolts at its upper and lower ends, respectively. The top seat is equipped with brush bristles that rotate with the rise and fall of the drill rod, and the base is equipped with a spiral scraper that matches the shape of the drill bit.

[0006] Furthermore, a bearing is embedded inside the top seat, and a nut for connecting with the threaded end of the external threaded pipe is fixed to the inner ring of the bearing. The bottom end of the bearing is connected to a fixing plate through several inclined connecting rods, and the middle of the fixing plate is provided with a central hole for the external threaded pipe to pass through. The bottom of the fixing plate is fixed with bristles for cleaning dust from the surface of the drill bit.

[0007] Furthermore, the bristles are made of nylon.

[0008] Furthermore, the outer wall of the cleaning chamber is provided with several discharge holes arranged in a spiral pattern.

[0009] Compared with the prior art, the present invention has the following advantages:

[0010] Compared to the traditional method of centrifugal swinging, this method first cleans the soil attached to the drill bit using the bottom-fitted spiral scraper 15, scraping away the soil adhering to and stuck in the inclined groove, and then brushing away the residue with bristles. This ensures the cleanliness of the drill bit and prevents personnel from being unable to observe the drill bit due to excessive soil accumulation during use. Attached Figure Description

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Example

[0017] like Figures 1 to 3 As shown, this embodiment provides a spiral anchor drilling machine with self-cleaning function, including an anchor drilling rig 1, a support frame 2 installed on the head of the anchor drilling rig 1, and a drill bit assembly installed on the head of the anchor drilling rig 1. The drill bit assembly includes an adjusting arm, a drive mechanism, a rotating shaft, a drill rod, and a drill bit 3, all of which are existing spiral anchor drilling machine structures, and will not be described in detail. The drive mechanism (diesel engine, motor, etc.) drives the drill bit 3 connected to the drill rod to work through the rotating shaft. The positioning beam at the support frame 2 is inclined and has a vertically set stabilizing seat installed. The bottom of the stabilizing seat has a cleaning chamber 5 installed. The cleaning chamber 5 is penetrated by the drill rod, and the outer surface of the drill rod is fixedly fitted with an external threaded tube 4. At the same time, the outer wall of the cleaning chamber 5 has several spirally distributed discharge holes 13. Correspondingly, the inner wall of the base 14 also has corresponding holes corresponding to the discharge holes 13. The significance of the discharge holes 13 is that when the soil is brushed by the brush bristles 12, it can be discharged from here, reducing the amount of soil adhering to the inner wall of the cleaning chamber 5.

[0018] The top and bottom ends of the cleaning chamber 5 are respectively fixed with a top seat 6 and a base 14 by bolts. The top seat 6 is equipped with brush bristles 12 that rotate with the drill rod. The base 14 is equipped with a spiral scraper 15 that matches the shape of the drill bit 3, so that the spiral drill bit 3 can pass through. That is, the arc surface of the drill bit 3 is in contact with the arc surface of the spiral scraper 15. As the drill bit 3 rotates (moves up and down), the soil (soil produced by drilling) that is filled between each spiral is scraped and cleaned.

[0019] In detail, the top seat 6 is internally embedded with a bearing 7. The inner ring of the bearing 7 is fixed with a nut 8 that is threaded to the end of the external threaded tube 4. The bottom end of the bearing 7 is connected to a fixing plate 10 through several inclined connecting rods 9. The fixing plate 10 has a central hole 11 for the external threaded tube 4 to pass through. The bottom of the fixing plate 10 is fixed with bristles 12 for cleaning dust from the surface of the drill bit 3. The bristles 12 are made of nylon or steel brush, depending on the need. It is sufficient to have a certain degree of durability and cleaning power. When the external threaded tube 4 rotates normally, that is, when the adjusting arm moves up, it drives the drill bit 3, which has stopped working, to move up. The transmission between the lead screw (i.e., the external threaded tube 4) and the lead screw nut (i.e., the nut 8) is simulated to drive the meshing nut 8 to rotate. The connecting rods 9 drive the fixing plate 10 to rotate, thereby realizing the rotation of the bristles 12 and completing the cleaning of the drill bit 3.

[0020] It should be noted that the structure described in this utility model can be implemented in many different forms and is not limited to the embodiments described. Any equivalent transformations made by those skilled in the art based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, such as the loading and unloading of other items, are included within the protection scope of this utility model.
