Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0027] Embodiment one:

[0028] Please refer to Figures 1 to 4 As shown in the figure, a kind of silt cleaning device of farmland water conservancy gate, comprising:

[0029] Mounting frame 1;

[0030] The mounting frame 1 is provided with two, the opposite upper parts of the two mounting frames 1 are commonly provided with an adjusting mechanism 2, the inner walls of the two sides of the two mounting frames 1 are commonly provided with a limiting rod 3, and the outer surfaces of the two limiting rods 3 are provided with a dredging mechanism 4;

[0031] The adjusting mechanism 2 comprises an adjusting box 21, an adjusting frame 22, a reinforcing block 23 and an electric telescopic rod 24, the adjusting frame 22, the reinforcing block 23 and the electric telescopic rod 24 are provided with two, the two adjusting frames 22 are movably installed at the two ends of the adjusting box 21, the two reinforcing blocks 23 are installed on the opposite sides of the two adjusting frames 22, and the two reinforcing blocks 23 are installed on the outer surfaces of the two limiting rods 3, and the two electric telescopic rods 24 are installed on the outer sides of the bottom ends of the two adjusting frames 22.

[0032] It can be known that Figure 2 and Figure 3 The top end of the first bevel gear 26 is installed on the top inner wall of the adjusting box 21 through a bearing, the opposite sides of the adjusting box 21 are commonly provided with a positive and negative screw rod 27 through a bearing, and the outer surface of the positive and negative screw rod 27 is provided with a second bevel gear 28.

[0033] It can be known that, when the dredging device is used, first, the adjusting box 21 is installed on the gate, then, the dredging device is adjusted according to the actual width of the gate, the first bevel gear 26 is driven to rotate by starting the driver 25, at this time, the first bevel gear 26 and the second bevel gear 28 are meshed and transmitted, the positive and negative screw rod 27 is driven to rotate, and then the two adjusting frames 22 installed thereon move outward, at the same time, the two electric telescopic rods 24 also drive the two dredging mechanisms 4 to expand outward, and the two reinforcing blocks 23 respectively push the two mounting frames 1 to move outward, when the width is adjusted to be appropriate, the two mounting frames 1 are also fixedly installed on the gate, in this way, by adjusting the spacing between the two mounting frames 1, the dredging device can be suitable for gates of different widths, so that the dredging operation of the gates of different widths is facilitated, which not only expands the application range of the dredging device, but also improves the flexibility and working efficiency thereof in use.

[0034] Specifically, as shown in Figure 2 and Figure 3 The first bevel gear 26 is meshed with the second bevel gear 28, the positive and negative screw rod 27 is threadedly connected with the adjusting frame 22, and the electric telescopic rod 24 is provided in a multi-section telescopic structure.

[0035] As can be seen from the above, the rotation of the positive and negative screw rod 27 can be used to drive the movement of the adjusting frame 22, and the linear movement of the adjusting frame 22 can be controlled when the positive and negative screw rod 27 rotates, so as to adjust the overall width of the dredging device. The electric telescopic rod 24 provides variable length and telescopic ability, which can be stretched to different lengths as needed.

[0036] Embodiment two:

[0037] Referring to Figure 1 and Figure 4 As shown in the figure, the outer wall of the two dredging mechanisms 4 is provided with a fixed frame 5, the opposite side of the two fixed frames 5 is provided with an electric push rod 6, the output end of the two electric push rods 6 is provided with a moving block 7, and the top end of the two moving blocks 7 is provided with a mud suction pipe 8.

[0038] The dredging mechanism 4 comprises a moving plate 41, a limiting block 42, a guide hole 43, a limiting groove 44 and a dredging scraping strip 45. The limiting block 42 is installed on one side of the bottom end of the moving plate 41, the guide hole 43 is opened on the other side of the top end of the moving plate 41, and the guide hole 43 is in sliding connection with the limiting rod 3. The limiting groove 44 is opened in the middle of the top end of the moving plate 41, and the dredging scraping strip 45 is installed on the outer wall of the other side of the moving plate 41.

[0039] As can be seen from the above, in the process of adjusting the position of the adjusting frame 22 by the adjusting mechanism 2, the two electric telescopic rods 24 drive the two moving plates 41 to expand outward, at this time, the limiting block 42 on the moving plate 41 is in sliding connection with the corresponding limiting groove 44, which ensures the stable sliding and limiting of the two moving plates 41. In this way, the two moving plates 41 can move position along with the adjustment of the adjusting mechanism 2. When it is necessary to dredge the gate, the electric telescopic rod 24 is elongated to push the moving plate 41 to move downward, at the same time, the guide hole 43 slides on the limiting rod 3 to provide stable guiding and limiting effect, which ensures the smooth upward and downward movement of the moving plate 41. At this time, the dredging scraping strip 45 can effectively clean the sludge on the gate with different widths, preventing the sludge from corroding the gate. In addition, the telescopic movement of the moving plate 41 can also stir the sludge and water, which facilitates the extraction of the mixed sludge water through the mud suction pipe 8 to realize the dredging function. At the same time, the telescopic adjustment of the electric push rod 6 can adjust the position of the moving block 7, so that the moving block 7 drives the mud suction pipe 8 to move, thereby realizing the dredging of different positions of the gate.

[0041] From the above, the limiting block 42 of the convex structure can be embedded into the corresponding limiting groove 44 to provide positioning and limiting functions, the dredging scraper 45 of the triangular structure has sharp edges that can better scrape the silt on the gate, and when the width of the dredging scraper 45 matches the thickness of the wall of the mounting frame 1, it can be more closely attached to the gate, the I-shaped moving block 7 is in sliding connection with the fixed frame 5, and can play a limiting role to improve stability.

[0042] Application example:

[0043] The design is mainly applied to the gate dredging work of the river, irrigation channel and drainage system in the farmland water conservancy project, and the farmland irrigation and drainage system usually depends on the river and irrigation channel, but the waterway is easy to accumulate silt, thereby affecting the smooth water flow and irrigation efficiency, the silt accumulated on the gate not only reduces the working efficiency of the gate, but also may cause corrosion and damage to the gate structure; the design can adjust the width of the entire dredging device according to the actual width of the gate by setting the adjusting mechanism 2, and this design makes the dredging device adapt to gates of various widths, improves the universality and flexibility of the dredging device, and simultaneously, the silt on the gate of different widths can be conveniently cleaned by setting the dredging mechanism 4, so that the corrosion and damage of the silt to the gate structure are effectively prevented, and the service life of the gate is prolonged.
