The bucket is usually composed of a bottom plate, side plate, lug plate, side plate, bucket lug plate, bucket lug sleeve, bucket teeth, and tooth seat. Its structural strength and durability directly affect the excavator's operating efficiency and lifespan.

[0003] Chinese utility model application No. 201920936882.0 discloses an excavator bucket for excavating trapezoidal drainage ditches, including a bucket body. Scraping devices are detachably installed on both sides of the bucket body. The scraping devices consist of a triangular scraper and a transverse scraper. The triangular scraper is a right-angled triangle structure, with one right-angled side fixed to the side wall of the bucket body and the hypotenuse of the triangular scraper pointing downwards. The transverse scraper is fixed to the top of the triangular scraper on the side away from the bucket body. However, in actual use, due to different functions of the drainage ditch, the slope of the side wall varies. This device can only scrape the side wall at the same angle and cannot adjust the angle as needed, resulting in low practicality. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5This utility model provides a technical solution: a telescopic bucket for trenching equipment, including a bucket body 1. Two fixing blocks 4 are connected to both sides of the bucket body 1, and each fixing block 4 has an insertion groove 6. An insertion block 3 is inserted into the insertion groove 6, and the two insertion blocks 3 are connected to the same adjusting device 8 on one side. The adjusting device 8 includes a support box 802. A side plate 801 is rotatably connected to one side of the inner wall of the support box 802. A movable groove 807 is opened at the top of the side plate 801. Second rotating grooves 806 are opened on both sides of the inner wall of the movable groove 807, and second rotating rods 808 are rotatably connected within the second rotating grooves 806. The two second rotating rods 808 are connected to the same second support block 805. The top of the support box 802... A connecting groove 809 is provided, and a first rotating groove 810 is provided on both sides of the inner wall of the connecting groove 809. A first rotating rod 811 is rotatably connected in the first rotating groove 810, and the two first rotating rods 811 are connected to the same first support block 804. A nut is embedded in the first support block 804, and a second threaded rod 812 is threadedly connected to the nut. A nut 803 is connected to the top of the second threaded rod 812. One side of the support box 802 is connected to one side of the plug-in block 3, and the bottom of the second threaded rod 812 is rotatably connected to the top of the second support block 805. A through hole is provided on one side of the inner wall of the plug-in groove 6, and a bolt 5 is inserted into the through hole. Another nut is embedded in one side of the plug-in block 3, and the other nut is threadedly connected to one end of the bolt 5.

[0029] In a specific implementation, by setting an adjustment device 8, the nut 803 is rotated using a wrench, causing the nut 803 to drive the second threaded rod 812 to rotate. Then, through the nut inside the first support block 804, the second threaded rod 812 moves downward through the thread inside the nut. Furthermore, the first support block 804 and the second support block 805 rotate around the first rotating rod 811 and the second rotating rod 808 respectively, causing the bottom of the second threaded rod 812 to drive the side plate 801 to rotate around the bottom through the second support block 805. This allows for angle adjustment of the side plate 801, thereby satisfying the requirements of different ditch sidewall scraping angles. When used horizontally, and within the applicable range of the device, by setting a retaining inclined surface on one side of the movable groove 807, the second threaded rod 812 is prevented from contacting the inner wall of the movable groove 807 when rotating, thus avoiding affecting the movement of the second threaded rod 812. By rotating the bolt 5, the bolt 5 is disengaged from the nut in the plug block 3, and then the support box 802 is moved upward to remove the support box 802, thus avoiding the support box 802 from affecting the digging efficiency of the bucket body 1. Moreover, the plug groove 6 is connected vertically, so that after soil enters the plug groove 6, the plug groove 6 can be cleared from top to bottom to prevent the plug groove 6 from being blocked by soil and affecting its use.

[0030] A leveling device 7 is connected to the bottom of the bucket body 1. The leveling device 7 includes a support plate 702. The top of the support plate 702 has an installation groove 701. A scraper 708 is slidably connected in the installation groove 701. A through groove 707 is opened in the scraper 708. A threaded sleeve 706 is embedded in the through groove 707. A first threaded rod 705 is threadedly connected to the inner wall of the threaded sleeve 706. One end of the first threaded rod 705 is connected to a knob 703. The top of the support plate 702 is connected to the bottom of the bucket body 1, and the installation groove 701... A bearing is embedded on one side of the wall, and the inner wall of the bearing is rotatably connected to the outer wall of the knob 703. Two support grooves are opened in the scraper 708, and a support rod 704 is slidably connected in the support groove. One end of the support rod 704 is connected to one side of the inner wall of the mounting groove 701. Two limiting grooves are opened in the inner wall of the support groove, and a limiting block 709 is slidably connected in the limiting groove. One side of the limiting block 709 is connected to the outer wall of the support rod 704. A connector 2 is connected to the top of the bucket body 1, and the connector 2 is connected to the telescopic arm of the excavator through a pin.

[0031] In a specific implementation, a leveling device 7 is provided. By rotating a knob 703, the knob 703 drives the first threaded rod 705 to rotate. The first threaded rod 705 drives the scraper 708 to move to one side through a threaded sleeve 706, so that the scraper 708 moves to one side of the bucket body 1 and moves out to the shovel teeth, thereby leveling the bottom of the ditch. This avoids digging pits that would affect the flatness of the ditch bottom when using the bucket body 1 for leveling. A support rod 704 is provided to limit and support the scraper 708, preventing the scraper 708 from shifting left or right during use and affecting the leveling effect. The connecting piece 2 can be installed and connected to the telescopic arm through a pin, so that the bucket body 1 can move back and forth to meet the needs of digging ditches of different depths. This telescopic arm technology is existing technology and does not need to be described in detail.

[0032] Working principle: During use, when the bucket body 1 is leveling the bottom of the ditch, the knob 703 is rotated, causing the first threaded rod 705 to rotate. The first threaded rod 705 moves the threaded sleeve 706, which in turn moves the scraper 708. One side of the scraper 708 moves to the side of the shovel teeth, leveling the bottom of the ditch and preventing unevenness from affecting subsequent processes. When leveling the sidewalls of the ditch, the nut 803 is rotated, causing the second threaded rod 812 to rotate. This causes the second threaded rod 812 to move to one side through the nut in the first support block 804. This causes the second threaded rod 812 to move to one side through the second threaded rod 805. The second support block 805 then rotates the side plate 801 around the bottom through the second rotating rod 808, allowing the side plate 801 to form different leveling angles to meet the leveling requirements of ditch sidewalls with different slopes, thus improving the practicality of the device.
