The interior of the movable seat 5 is laterally connected with a double-acting screw 23, and the two sides of the exterior of the double-acting screw 23 are respectively threaded with threaded sleeves 24. The right side of the double-acting screw 23 passes through the interior of the right side of the movable seat 5 and is fixed with a handle 17. The interior of the front end of the movable seat 5 is provided with a movable groove 6. The top and bottom of the front ends of the two sets of mounting plates 7 are respectively provided with reserved holes 18. The front ends of the two sets of threaded sleeves 24 pass through the interior of the movable groove 6 and are fixedly connected to the rear ends of the two sets of mounting plates 7. The reserved holes 18 pass through the interior of the mounting plates 7. Three sets of reserved holes 18 are provided at equal intervals at the top and bottom of the front end of the mounting plates 7.
[0028] Specifically, as shown in Figures 1, 2, and 4, when the metering screen is installed at the front end of the frame 2, the bidirectional lead screw 23 can be driven to rotate by rotating the handle 17 on the right side of the movable seat 5. The rotation of the bidirectional lead screw 23 simultaneously drives the two sets of mounting plates 7 to move inward or outward on both sides of the front end of the movable seat 5 using two sets of threaded sleeves 24. By adjusting the installation distance between the two sets of mounting plates 7, the metering screen can be adapted to install metering screens of different widths, improving the adaptability of the telescopic frame. After adjusting the two sets of mounting plates 7 to the appropriate position, the reserved holes 18 inside the mounting plates 7 are used to assist in the installation of the metering screen.
[0029] The front end of the frame 2 is provided with an installation groove 3, and the four corners of the rear end of the installation groove 3 are provided with installation holes 4. The installation groove 3 is provided with a cover plate 9, and the four corners of the front end of the cover plate 9 are provided with installation bolts 10. The front ends of the frame 2 are provided with inner grooves 11 on both sides, and an inner frame 12 is fixed inside the inner groove 11. Several scrapers 13 are fixed inside the inner frame 12 on both sides. The middle position of the front end of the cover plate 9 is provided with an inner groove 20, and an inner frame 21 is fixed inside the inner groove 20. Several scrapers 22 are fixed inside the inner frame 21 on both sides. The front end of the sliding sleeve 28 penetrates the interior of the inner frame 12, and the front end of the threaded sleeve 19 can penetrate the interior of the inner frame 21.
[0030] The rear end of the mounting bolt 10 passes through the interior of the cover plate 9 and is threaded into the mounting hole 4. Several scraper brushes 13 are distributed at equal intervals on both sides of the interior of the inner frame 12, and several scraper brushes 22 are distributed at equal intervals on both sides of the interior of the inner frame 21.
[0031] Specifically, as shown in Figures 1-5, a cover plate 9 is installed inside the front end of the frame 2. The cover plate 9 can be used to cover and seal the inside of the frame 2. The sliding sleeve 28 and the threaded sleeve 19 can move up and down in the inner frame 12 and the inner frame 21 respectively, which facilitates dust prevention inside the telescopic frame.
[0032] A side cover 25 is provided at the rear end of the frame 2, and a fixing bolt 27 is provided at the four corners on both sides of the side cover 25. Four sets of side holes 26 are opened inside both sides of the frame 2. The fixing bolt 27 passes through the inside of the side cover 25 and is rotatably connected in the side hole 26.
[0033] Specifically, as shown in Figures 1 and 4, a side cover 25 is installed and fixed on the outside of the telescopic frame, which can be used to provide auxiliary outer cover anti-collision protection for the outside of the frame 2.
[0034] Mounting feet 1 are fixed to the bottom ends of both sides of the frame 2. A reducer 14 is fixed to the top of the frame 2, and a servo motor 15 is installed on the right side of the reducer 14. The output shaft of the servo motor 15 is fixedly connected to the input shaft of the reducer 14. The output shaft of the reducer 14 is fixedly connected to the top end of the one-way lead screw 16. The front end of the threaded sleeve 19 is fixedly connected to the middle position of the rear end of the movable seat 5. Two sets of sliding sleeves 28 are fixedly connected to the two sides of the rear end of the movable seat 5 respectively.
[0035] Working Principle: When using this invention, the metering screen is installed at the front end of the frame 2. The bidirectional lead screw 23 is driven to rotate by turning the handle 17 on the right side of the movable seat 5. Simultaneously, the rotation of the bidirectional lead screw 23, using two sets of threaded sleeves 24, drives two sets of mounting plates 7 to move inwards or outwards on both sides of the front end of the movable seat 5. By adjusting the installation distance between the two sets of mounting plates 7, it can accommodate metering screens of different widths. After adjusting the two sets of mounting plates 7 to the appropriate position, the pre-drilled holes 18 inside the mounting plates 7 assist in the installation of the metering screen. When the metering screen is installed at the front end of the frame 2, the servo motor 15 is started and the reducer 14 drives the one-way screw 16 to rotate. Simultaneously, the screw 16 rotates, and the threaded sleeve 19 drives the movable seat 5 and the metering screen installed at the front end to move vertically. A cover plate 9 is installed inside the front end of the frame 2 to provide auxiliary dust protection and sealing. The sliding sleeve 28 and the threaded sleeve 19 can move vertically within the inner frame 12 and inner frame 21, respectively. Furthermore, a side cover 25 is installed and fixed on the outside of the telescopic frame to provide auxiliary external impact protection for the frame 2.
