Technical Field
[0001] This invention relates to the field of ground drilling technology, specifically to an improved excavator bucket structure for realizing mechanized ground drilling. Background Technology
[0002] During line construction, many scenarios require the installation of a large number of ground drills (ground anchors). Relying solely on manual installation requires a large workforce and takes a long time. Furthermore, workers who are constantly turning around are prone to symptoms such as dizziness and nausea. If the terrain is unfavorable or the weather is bad, the installation becomes even more difficult.
[0003] To address the problems encountered during the installation of ground anchors, domestic research has focused on various aspects. For example, patent publication CN109356520B discloses a drilling device for a mobile ground anchor, comprising: a power source, a hydraulic control device, a power head connecting arm, and a power head connected in sequence; the power head is connected to the ground anchor; the hydraulic control device is used to drive the power head to output torque based on the energy provided by the power source, thus drilling the ground anchor into the ground. This invention can be widely applied in the installation of rigid pole ground anchors, directly improving the safety and reliability of construction operations. It enables hydraulically driven drilling of ground anchors, avoiding manual screwing, and facilitates convenient and quick on-site transport and relocation, solving the current construction difficulties of ground anchors in overhead line construction.
[0004] However, the aforementioned ground anchor drilling device still has significant limitations in application and is difficult to adapt to diverse construction scenarios: First, the device relies on an independent power source and hydraulic control system, resulting in a large overall equipment size and fixed structure. In large-scale construction areas such as open plains and hills, a lot of manpower is still required, which cannot effectively improve the efficiency of ground drilling. Second, the device cannot be disassembled as a whole, and the working radius of its power head connecting arm is fixed. In narrow construction areas such as dense forest areas, building gaps, and the bottom of power poles, the entire device is difficult to enter and cannot complete the ground drilling operation. It can only revert to manual operation mode. Therefore, an improved excavator bucket structure for realizing mechanized ground drilling is proposed. Summary of the Invention

[0021] Please see Figure 1-6An improved excavator bucket structure for realizing mechanized burial of earth drills includes an excavator rocker arm connecting assembly 1, an earth drill fixing mechanism 4 and a drive connecting assembly 6. A rotary cylinder 2 is movably installed at the bottom of the rocker arm connecting assembly 1. Three excavator hydraulic system connecting pipes 3 are fixedly installed on the outside of the rotary cylinder 2. An earth drill rod 5 is movably installed inside the earth drill fixing mechanism 4. The drilling rig fixing mechanism 4 includes a fixing plate 401, a connector 402, a cross connector rod 403, an equipment mounting plate 404, a threaded fixing rod 405, a threaded fixing seat 406, a drilling rig clamp 407, a limit rod 408, a limit nut 409, a drive motor 410, a handle 411, and an equipment box 412. The bottom output end of the rotary cylinder 2 is fixedly mounted with the fixing plate 401. The bottom of the fixing plate 401 is fixedly mounted with the connector 402. The cross connector rod 403 is inserted into the connector 402. The bottom of the cross connector rod 403 is movably mounted with the equipment mounting plate 404. The fixed plate 401 has two threaded fixing rods 405 rotatably connected inside. The bottom of the equipment mounting plate 404 has two threaded fixing seats 406 fixedly installed. The bottom of the cross-shaped plug rod 403 has a ground drill clamp 407 fixedly installed. The ground drill clamp 407 has a limit plug rod 408 movably installed inside. The limit plug rod 408 has a limit nut 409 threadedly connected to its exterior. The left side of the equipment mounting plate 404 has a drive motor 410 fixedly installed. The drive motor 410 has a handle 411 installed on its exterior. The bottom of the equipment mounting plate 404 has an equipment box 412 fixedly installed.
[0022] The drive connection assembly 6 includes a drive box 601, a drive wheel 602, a drive belt 603, a cross-shaped insertion groove 604, an extension hole 605, and a cross-shaped insertion shaft 606. Two drive wheels 602 are rotatably connected inside the drive box 601. The two drive wheels 602 are connected by a drive belt 603. The bottom of each of the two drive wheels 602 is provided with a cross-shaped insertion groove 604. The top and bottom of the drive box 601 are provided with two extension holes 605. The output end of the drive motor 410 is fixedly mounted with a cross-shaped insertion shaft 606. Example 1:
[0023] This embodiment is applicable to large-scale underground drilling operations in open construction areas such as plains and hills. It relies on the power of the excavator itself to achieve mechanized construction. The specific operation process and structural principles are as follows: I. Structural Pre-assembly First, insert the top of the drill rod 5 into the U-shaped groove of the drill clamp 407 in the drill fixing mechanism 4, so that the drill rod 5 fits tightly with the semi-circular limiting groove at the bottom of the equipment mounting plate 404; then, insert the end of the limiting rod 408 through the left groove wall of the drill clamp 407, the through hole reserved at the top of the drill rod 5, and the right groove wall of the drill clamp 407 in sequence; finally, tighten the limiting nut 409 and the exposed end of the limiting rod 408 to complete the fixing of the drill rod 5. During this process, the anti-slip rubber pad on the inner wall of the drill clamp 407 can increase the contact friction and prevent the drill rod 5 from slipping when rotating. The cross-shaped connector 403 on the top of the equipment mounting plate 404 is precisely aligned with the connector 402 at the bottom of the fixing plate 401, so that the top of the cross-shaped connector 403 fits tightly against the inner wall of the connector 402. Then, the threaded fixing rod 405 inside the fixing plate 401 is turned with a hexagonal drive tool so that its bottom end passes through the fixing plate 401 and is screwed into the threaded fixing seat 406 at the bottom of the equipment mounting plate 404, thus completing the detachable fastening connection between the fixing plate 401 and the equipment mounting plate 404. The overall structure is connected to the excavator rocker arm by the excavator rocker arm connection assembly 1. At the same time, the three excavator hydraulic system connection pipes 3 on the outside of the rotary cylinder 2 are connected to the excavator hydraulic circuit, so that the rotary cylinder 2 can obtain hydraulic power from the excavator body.
[0024] II. Mechanized Burying Operations The operator manipulates the excavator boom to adjust the spatial position of the overall structure, aligning the bottom end of the drill rod 5 with the burial point; the operator starts the excavator's hydraulic system, and hydraulic oil is input into the rotary cylinder 2 through the excavator's hydraulic system connecting pipe 3, driving the fixed plate 401 at the bottom output end of the rotary cylinder 2 to drive the entire drill fixing mechanism 4 and the drill rod 5 to rotate synchronously; at the same time, the operator slowly presses down the excavator boom, causing the drill rod 5 to rotate into the ground at a uniform speed, completing the mechanized burial. Example 2:
[0025] This embodiment is suitable for drilling operations in narrow construction areas such as densely wooded areas, building gaps, and the base of power poles. It relies on the detachable structure and self-powered capability to achieve portable construction. The specific operation process and structural principles are as follows: I. Structural Decomposition and Reorganization First, unscrew the threaded fixing rod 405, release the fastening connection between the fixing plate 401 and the equipment mounting plate 404, and disassemble the entire ground drill fixing mechanism 4 from the rotating cylinder 2; then, put the drive box 601 in the drive connection assembly 6 onto the top of the cross-shaped plug rod 403 and the cross-shaped plug shaft 606 of the drive motor 410, so that the extension holes 605 at the top and bottom of the drive box 601 are aligned with the fixing seat 406, and at the same time ensure that the two plug holes at the bottom of the drive box 601 are adapted to be connected to the top of the cross-shaped plug rod 403 and the cross-shaped plug shaft 606 respectively, and the cross-shaped plug grooves 604 at the bottom of the two transmission wheels 602 are respectively engaged with the top of the cross-shaped plug rod 403 and the cross-shaped plug shaft 606. It was confirmed that the battery inside the equipment box 412 had sufficient power, the charging interface on its side wall had been pre-charged, and the power cable of the drive motor 410 had passed through the equipment mounting plate 404 and was electrically connected to the control circuit board inside the equipment box 412.
[0026] II. Portable Burial Operation The construction worker holds the handle 411 on the outside of the drive motor 410. The anti-slip foam cover on the outside of the handle 411 can improve the grip comfort. The bottom end of the drill rod 5 is aligned with the burial point in the narrow area. The drive motor 410 is started. The cross-shaped plug shaft 606 at its output end drives the bottom transmission wheel 602 to rotate. After being transmitted by the transmission belt 603, it synchronously drives the other side transmission wheel 602 and the cross-shaped plug rod 403 to rotate, thereby driving the drill rod 5 in the drill clamp 407 to screw into the ground and complete the burial of the drill in the narrow area. During this process, the rubber shock-absorbing pad at the connection between the equipment box 412 and the equipment mounting plate 404 can reduce the vibration of the drive motor 410 during operation.
[0027] In summary, this improved excavator bucket structure for mechanized burial of earth drills connects to the excavator via the excavator boom connecting assembly 1, and connects the rotating cylinder 2 to the excavator hydraulic system via the excavator hydraulic system connecting pipe 3 to obtain power. It eliminates the need for an independent power source and hydraulic control system. Furthermore, the fixing plate 401 and the equipment mounting plate 404 are securely connected by the threaded fixing rod 405 and the threaded fixing seat 406. Taking advantage of the excavator's wide operating range, the earth drill rod 5 in the earth drill clamp 407 is efficiently driven into the ground in open areas, significantly reducing manpower input and improving burial efficiency, thus solving the problem of low efficiency in open areas of traditional devices.
[0028] Furthermore, the improved excavator bucket structure used for mechanized burial drilling can, when entering a narrow area, unscrew the threaded fixing rod 405 to separate the burial drilling fixing mechanism 4 from the rotating cylinder 2. After assembling the drive connection assembly 6, the battery in the equipment box 412 supplies power to the drive motor 410, which rotates the cross-connecting rod 403 via the cross-connecting shaft 606, the transmission wheel 602, and the transmission belt 603. Construction personnel can then hold the handle 411 to complete the burial, avoiding the need to revert to the original manual operation. This solves the problem that traditional devices cannot enter narrow areas and addresses the issue of poor adaptability of existing mechanized ground anchor drilling devices, which cannot meet the needs of both open and narrow area operations.
