Description

Technical Field

[0001] This utility model relates to the field of bottom cleaning drill bit improvement technology, specifically, a quick-opening and closing door-type bottom cleaning drill. Background Technology

[0002] In fields such as building construction, transportation infrastructure construction, and water conservancy projects, pile foundation construction is a crucial step in ensuring structural stability. Rotary drilling rigs, with their advantages of high drilling efficiency, strong adaptability, and environmentally friendly operation, have become core equipment in pile foundation drilling. Rotary drilling rigs break up rock and soil through the rotating cutting action of the drill bucket, loading the broken material into the bucket and lifting it to the ground, thus achieving drilling operations. However, in the actual drilling process, due to the gap between the bottom of the drill bucket and the bottom of the hole, and the fact that some fine granular soil is produced after the rock and soil are broken, this soil is difficult to completely capture and remove from the hole, resulting in a certain thickness of sediment layer remaining at the bottom of the hole.

[0003] Therefore, a bottom cleaning drill is needed to remove the remaining sediment layer at the bottom of the hole. However, existing bottom cleaning drills, due to the need to collect sediment during the cleaning process, have a difficult-to-quickly open and close mechanism for the collection port. If it remains open, the sediment collection efficiency is affected; if it is closed, the bottom sediment cannot be collected. Utility Model Content

[0004] The purpose of this invention is to provide a quick-opening and closing door-type bottom cleaning drill, so that the bottom slag collection port can be opened quickly during bottom cleaning and can be closed quickly when slag needs to be lifted.

[0005] To achieve the above objectives, the present invention employs the following technical means: A quick-opening and closing door-type bottom cleaning drill, comprising: A cylindrical body with an open bottom surface and a circular door panel hinged thereto. The door panel has symmetrical feed inlets arranged around its axis, and the top surface of the body is constructed with a mounting plate. The rotating mechanism includes a positioning tube that passes through the door panel and is rotatably connected to the door panel. A drive shaft is rotatably installed inside the positioning tube. Both ends of the drive shaft extend out of the positioning tube. A scraper is installed at the bottom end of the drive shaft. A connecting ring is sleeved on the top end of the drive shaft. The connecting ring is coaxially located above the positioning tube. The connecting ring and the drive shaft are positioned and connected by a pin. A positioning groove is provided around the top end of the connecting ring along its axis. A magnet ring is coaxially installed on the top end of the positioning tube. The top surface of the magnet ring is magnetically attached to the bottom surface of the connecting ring. A baffle is installed around the bottom side of the positioning tube along its axis. The number and position of the baffles match the feed inlet. A limit block is installed on the bottom surface of the door panel. The limit block is located close to the feed inlet. A fastening mechanism is provided on the side opposite to the hinge portion of the door panel, and is used to position the door panel.

[0006] Preferably, the fastening mechanism includes a drive mechanism disposed on the mounting plate, the drive end of the drive mechanism extending into the cylinder and fastening with the top surface of the door panel.

[0007] Furthermore, the driving mechanism includes a telescopic rod mounted on the mounting plate. The bottom end of the telescopic rod extends into the cylinder and is hinged to a hook mechanism. The hook end of the hook mechanism moves along an arc-shaped path. A buckle plate is provided on the top surface of the door panel along the movement path of the hook end, and the hook end is fastened to the buckle plate.

[0008] Furthermore, the scraper is constructed with an inclined guide plate. When the bottom end of the inclined surface of the guide plate faces the material, the feed inlet is in an open state. When the bottom end of the inclined surface of the baffle moves away from the material, the baffle blocks the feed inlet.

[0009] Furthermore, a connecting mechanism is coaxially mounted on the top surface of the mounting plate. The connecting mechanism is used to connect with the rotating part of the drilling rig. The rotating end of the drilling rig passes through the mounting plate and engages with the positioning groove.

[0010] Furthermore, the connecting mechanism includes a perforated mounting bracket installed on the top surface of the mounting plate, the mounting bracket having a clearance channel for the rotating end of the drilling rig to pass through.

[0011] This utility model has the following beneficial effects during use: When hole cleaning is required, the cylinder is inserted into the hole. When the scraper at the bottom of the drive shaft contacts the bottom surface of the hole, the rotating part of the drill is activated, causing the drill to drive the drive shaft to rotate. As the drive shaft rotates, the scraper at the bottom of the drive shaft is in scraping mode. At this time, the connecting ring rotates synchronously. Using the magnetic attraction of the magnetic ring, the connecting ring drives the positioning tube to rotate. When the positioning tube rotates, it can move the baffle, thus keeping the feed inlet open. As the baffle rotates, when the baffle abuts against the limit block, the baffle can no longer rotate, causing the magnetically attached connecting ring and magnetic ring to move relative to each other, thus ensuring that the feed inlet is always in the most open state. After cleaning is completed, the drive shaft is rotated in the opposite direction. Similarly, under the action of the magnetic ring, the connecting ring drives the positioning tube to rotate again, causing the baffle to abut against the other side of the limit block, thus completing the sealing of the feed inlet by the baffle. In this way, by simply controlling the rotation of the drive shaft, the feed inlet can be opened or closed during the material cleaning process using the scraper, which greatly saves preparation time in the cleaning process and improves cleaning efficiency and effect.

[0025] Please refer to Figures 1 to 6As shown, a quick-opening and closing door-type bottom cleaning drill includes: A cylindrical body 1 has an open bottom surface and a circular door panel 2 hinged to it. A feed inlet 3 is symmetrically arranged around the door panel 2 along its axis. A mounting plate 4 is constructed on the top surface of the cylindrical body 1. The rotating mechanism includes a positioning tube 5 that passes through the door panel 2 and is rotatably connected to the door panel 2. A drive shaft 6 is rotatably installed inside the positioning tube 5. Both ends of the drive shaft 6 extend out of the positioning tube 5. A scraper 7 is installed at the bottom end of the drive shaft 6. A connecting ring 8 is sleeved on the top end of the drive shaft 6. The connecting ring 8 is coaxially located above the positioning tube 5. The connecting ring 8 and the drive shaft 6 are positioned and connected by a pin 9. A positioning groove 10 is provided around the top end of the connecting ring 8 along its axis. A magnet ring 11 is coaxially installed on the top end of the positioning tube 5. The top surface of the magnet ring 11 is magnetically attached to the bottom surface of the connecting ring 8. A baffle 12 is installed around the bottom side of the positioning tube 5 along its axis. The number and position of the baffle 12 match the feed inlet 3. A limit block 13 is installed on the bottom surface of the door panel 2. The limit block 13 is located close to the feed inlet 3. A fastening mechanism is provided on the side opposite to the hinge portion of the door panel 2, and is used to position the door panel 2.

[0026] Thus, when hole cleaning is required, the cylinder 1 is inserted into the hole. When the scraper 7 located at the bottom of the drive shaft 6 contacts the bottom surface of the hole, the rotating part of the drill is activated, causing the drill to drive the drive shaft 6 to rotate. When the drive shaft 6 rotates, the scraper 7 at the bottom of the drive shaft 6 is in the scraping state. At this time, the connecting ring 8 rotates synchronously. Using the magnetic attraction of the magnet ring 11, the connecting ring 8 drives the positioning tube 5 to rotate. When the positioning tube 5 rotates, the positioning tube 5 can drive the state of the baffle 12, thereby keeping the feed inlet 3 in the open state. As the baffle 12 rotates, when the baffle 12 abuts against the limit block 13, the baffle 12 can no longer rotate, causing the magnetically attached connecting ring 8 and magnet ring 11 to move relative to each other, thereby ensuring that the feed inlet 3 is always in the maximum open state. After the material is cleaned, the drive shaft 6 rotates in the opposite direction. Similarly, under the action of the magnet ring 11, the connecting ring 8 drives the positioning tube 5 to rotate, causing the baffle 12 to abut against the other side of the limiting block 13, thus sealing the feed inlet 3 with the baffle 12. In this way, by simply controlling the rotation of the drive shaft 6, the feed inlet 3 can be opened or closed during the material cleaning process using the scraper 7, significantly saving preparation time during the cleaning process and improving cleaning efficiency and effectiveness.

[0027] Specifically, the fastening mechanism includes a drive mechanism disposed on the mounting plate 4, the drive end of the drive mechanism extending into the cylinder 1 and fastening with the top surface of the door panel 2.

[0028] Furthermore, the drive mechanism includes a telescopic rod 14 mounted on the mounting plate 4. The bottom end of the telescopic rod 14 extends into the cylinder 1 and is hinged to a hook mechanism 15. The hook end of the hook mechanism 15 moves along an arc-shaped path. A buckle plate 16 is provided on the top surface of the door panel 2 along the movement path of the hook end. The hook end is fastened to the buckle plate 16.

[0029] Further description: the scraper 7 is constructed with an inclined guide plate 17. When the bottom end of the inclined surface of the guide plate 17 faces the material, the feed inlet 3 is in an open state. When the bottom end of the inclined surface of the baffle moves away from the material, the baffle 12 blocks the feed inlet 3.

[0030] Furthermore, a connecting mechanism is coaxially mounted on the top surface of the mounting plate 4. The connecting mechanism is used to connect with the rotating part of the drilling rig. The rotating end of the drilling rig passes through the mounting plate 4 and engages with the positioning groove 10.

[0031] Meanwhile, the connecting mechanism includes a hollow mounting bracket 18 installed on the top surface of the mounting plate 4, and the mounting bracket is constructed with a clearance channel for the rotating end of the drilling rig to pass through.
