[0032] A slideway 30 is provided on one side of the two sliding shovel plates 3 close to the fixed shovel plate 2, a driving groove 22 is provided in the middle of the fixed shovel plate 2, and sliding grooves 21 are provided on both sides of the driving groove 22 and are connected to the driving groove 22 and penetrate the left and right side walls of the fixed shovel plate 2. A driving mechanism is provided in the driving groove 22 to move the sliding shovel plates 3 away from or close to the fixed shovel plate 2;

[0033] The driving mechanism includes a screw rod 23 rotatably connected in a driving groove 22, a driving block 24 is threadedly connected to the screw rod 23, one end of a connecting rod 31 is hinged at both ends of the driving block 24, and the other end of the connecting rod 31 is hinged in a slideway 30 of the sliding shovel plate 3 on the same side.

[0034] Among them, the connecting rod 31 is located in the driving groove 22 and the slide 30 on the same side, and the length of the connecting rod 31 is less than the sum of the driving groove 22 on one side and the slide 30 on the same side, which is used to limit the moving range of the movable sliding shovel plate 3 and prevent the slide 30 from detaching from the fixed shovel plate 2.

[0035] The wall thickness of the sliding shovel plate 3 is greater than that of the fixed shovel plate 2 , wherein the fixed shovel plate 2 and the sliding shovel plate 3 can temporarily store sludge, wherein the front walls of the fixed shovel plate 2 and the sliding shovel plate 3 are both inclined.

[0036] Optionally, in the above technical solution, a through hole 25 for the screw rod 23 to pass through is opened at the rear end of the fixed shovel plate 2, and a knob 26 is fixedly connected to one end of the screw rod 23 passing through the through hole 25.

[0037] Optionally, in the above technical solution, a fixed plate 20 is fixedly installed in the middle of the fixed shovel plate 2, and a guide column 28 symmetrical about the central axis is fixedly installed on the fixed plate 20, and a side scraper 35 is fixedly installed at one end of the two sliding shovel plates 3 away from the fixed shovel plate 2.

[0038] Optionally, in the above technical solution, a guide sleeve 36 is fixedly installed on one side of the side scrapers 35 that are close to each other, and the two guide sleeves 36 are slidably connected to the guide pillars 28 respectively.

[0039] Optionally, in the above technical solution, a top wall of the guide sleeve 36 is provided with a plurality of upper positioning holes 33 penetrating along its displacement direction, and a guide column 28 is provided with a plurality of lower positioning holes 27 matched with the upper positioning holes 33 .

[0041] Working principle:

[0042] When in use, the mobile frame 1 is placed on the bottom surface at a position corresponding to the river channel or ditch, and adjusted according to the required width. First, the positioning column 34 is removed;

[0043] When the width needs to be increased, the knob 26 is rotated clockwise to drive the screw 23 to rotate, so that the driving block 24 moves forward along the screw 23, driving the inner ends of the two connecting rods 31 to move forward, and the outer ends of the two connecting rods 31 push the sliding shovel plate 3 on the same side to move away from the moving frame 1, and at the same time, the guide sleeve 36 slides outward along the guide column 28, so that the device is opened;

[0044] When the width needs to be reduced, the knob 26 is rotated counterclockwise to drive the screw rod 23 to rotate in the opposite direction, so that the driving block 24 moves backward along the screw rod 23, driving the inner ends of the two connecting rods 31 to move backward, and the outer ends of the two connecting rods 31 pull the sliding shovel plate 3 on the same side to move closer to the fixed shovel plate 2, and at the same time, the guide sleeve 36 slides inward along the guide column 28 to close the device;

[0045] After the adjustment is completed, the positioning column 34 is inserted into any corresponding set of upper positioning holes 33 and lower positioning holes 27, and then the cylinder 10 is started to drive the fixed shovel plate 2 and the sliding shovel plate 3 to move to the appropriate position to scrape the sludge.

[0046] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
