[0028] like Figure 1-8 As shown, a silt removal device for a municipal engineering ditch 1 includes a base 2, a collection box 4 fixedly connected to the upper end of the base 2, a moving mechanism 3 and a sludge pumping mechanism 5, the moving mechanism 3 being connected to the lower side of the base 2 and the sludge pumping mechanism 5 being connected to the front end of the collection box 4.

[0029] like Figure 3-5As shown, the moving mechanism 3 includes a first motor 301, a support frame 306, and rollers 311. The first motor 301 is fixed to the front end of the base 2. The first motor 301 drives two support frames 306 to slide towards each other at the lower end of the base 2. Several rollers 311 are rotatably connected to the lower end of the support frames 306. A first bevel gear 302 is fixed to the output end of the first motor 301. Second bevel gears 303, symmetrically arranged on both sides of the first bevel gear 302, are meshed with each other. A first screw 304 is fixed to the second bevel gear 303. The two first screws 304 have the same pitch and opposite directions of rotation. A first slider 307, threadedly connected to the first screw 304, is fixed to the upper end of the support frame 306. A toothed groove 201 is provided in the base 2. The first bevel gear 302 and the second bevel gear 303 are both rotatably disposed in the toothed groove 201. A first sliding groove 202, symmetrically distributed on both sides of the toothed groove 201, is provided at the lower end of the base 2. The first screw 304 rotates horizontally to connect... The first slider 307 is slidably engaged within the first slide groove 202. The lower end of the base 2 has a limiting groove 203 parallel to the first slide groove 202. Horizontally distributed limiting rods 305 are fixedly connected within the limiting groove 203. The upper end of the support frame 306 has a limiting block 308 slidably engaged within the limiting groove 203 and slidably connected to the limiting rods 305. The lower end of the support frame 306 has several mounting grooves 309. A connecting rod 310 is fixedly connected, and the roller 311 is rotatably mounted on the connecting rod 310. Driven by the first motor 301, the two support frames 306 slide towards each other at the lower end of the base 2, thereby adjusting the distance between the two support frames 306 to adapt to the ditch 1 of different widths. When the support frames 306 move towards each other, the stability of the movement of the support frames 306 towards each other is improved by the sliding of the first slider 307 in the first slide groove 202 and the sliding of the limiting block 308 on the limiting rod 305 in the limiting groove 203.

[0030] like Figure 6-8As shown, the sludge pumping mechanism 5 includes a second motor 501, a sludge pumping shell 503, and a spiral conveyor plate 510. The sludge pumping shell 503 has an inlet hopper 505 and an outlet hopper 507 fixedly connected to its inner side, arranged vertically and communicating with it. The second motor 501 is fixedly connected to the upper end of the collection box 4. The second motor 501 drives the sludge pumping shell 503 to vertically rise and fall at the front end of the collection box 4, causing the inlet hopper 505 to extend into the silt at the bottom of the ditch 1. A third motor 508 is fixedly connected to the upper end of the sludge pumping shell 503. The third motor 508 drives the spiral conveyor plate 510 to rotate vertically within the sludge pumping shell 503. A second sluice groove 401 is opened at the front end of the collection box 4. A second screw 502, vertically rotatably connected to the output end of the lower end of the second motor 501, is fixedly connected to the second screw 502 within the second sluice groove 401. A vertically sliding fit within the second sluice groove 401 and threadedly connected to the second screw 502 is fixedly connected to the inner side of the sludge pumping shell 503. The second slider 504 is fixed to the output end of the third motor 508, which is vertically rotatably connected to the mud-collecting shell 503. The spiral conveying plate 510 is fixed to the connecting shaft 509 and rotatably fits against the inner wall of the mud-collecting shell 503. The mud-inlet hopper 505 and the mud-outlet hopper 507 are both inclined. The lower end of the mud-inlet hopper 505 is provided with a sawtooth structure 506. The upper end of the collection box 4 is open. The mud-outlet hopper 507 extends to the upper side of the collection box 4. Driven by the second motor 501, the mud-collecting shell 503 is vertically raised and lowered at the front end of the collection box 4, so that the mud-inlet hopper 505 extends into the silt in the ditch 1. When the mud-collecting shell 503 moves horizontally with the moving mechanism 3, the silt enters the mud-collecting shell 503 from the mud-inlet hopper 505. When the spiral conveying plate 510 is driven to rotate by the third motor 508, the silt rises in the mud-collecting shell 503 and enters the collection box 4 from the mud-outlet hopper 507 for collection.

[0031] In use, this invention utilizes the output of a first motor 301 to drive a first bevel gear 302 to rotate, which in turn drives a symmetrical second bevel gear 303 to rotate. This, in turn, drives two first screws 304 with the same pitch but opposite directions to rotate, which in turn drives the first slider 307 to slide towards each other within the first groove 202. This, in turn, drives the support frame 306 to slide towards each other at the lower end of the base 2. Simultaneously, a limiting block 308 slides on a limiting rod 305 within the limiting groove 203 to improve the stability of the support frame 306's movement. The two support frames 306 slide towards each other to adjust their spacing to match the width of the ditch 1 requiring silt removal. The base 2 is then placed on the upper end of the ditch 1. The structure utilizes the output of the second motor 501 to drive the second screw 502 to rotate, which in turn drives the second slider 504 to slide within the second slide groove 401, thereby causing the mud-collecting shell 503 to descend vertically and the mud-feeding hopper 505 to extend into the silt at the bottom of the ditch 1. The moving mechanism 3 moves along the ditch 1, thereby driving the mud-feeding hopper 505 to move within the silt of the ditch 1, and then shovels the silt into the mud-collecting shell 503. The output of the third motor 508 drives the connecting shaft 509 to rotate, which in turn drives the screw conveyor plate 510 to rotate, thereby causing the silt to rise within the mud-collecting shell 503 and then be discharged from the mud-discharge hopper 507 into the collection box 4, thus cleaning the silt in the ditch 1.

[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
