Description

Technical Field

[0001] This utility model belongs to the field of river silt removal technology, specifically a river silt removal device for small watershed management. Background Technology

[0002] Small watersheds play a vital role in ecosystems, serving as fundamental components of larger watersheds. They are crucial for regional water resource conservation, soil and water conservation, and biodiversity protection. Within small watersheds, river channels are essential watercourses. However, over time, large amounts of silt accumulate in these channels. This silt not only reduces the river's flood control capacity but also affects water quality and damages the river's ecological environment. Therefore, river dredging is of paramount importance in small watershed management. During silt removal, it is common to encounter situations where large amounts of weeds and aquatic plants grow in the riverbed. Traditional dredging equipment often lacks specific mechanisms for dealing with weeds and aquatic plants. When the equipment is in operation, these weeds and aquatic plants easily become entangled in the components, hindering the normal operation of the dredging equipment and reducing dredging efficiency. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a river silt removal device for small watershed management, which solves the problem of weeds and aquatic plants entangled in the process of river silt removal, which hinders the normal operation of the silt removal device, causes frequent equipment failures, and reduces silt removal efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a river silt removal device for small watershed management, comprising a base plate, a support bracket fixedly installed above the base plate near its side, a support screw rotatably connected between the inner walls of the support bracket, the support screw being a vertical design, a connecting slider threadedly connected to the outer wall of the support screw, a control motor fixedly installed at the top of the support bracket, the output end of the control motor being connected to one end of the support screw, a fixed bracket fixedly connected to one side of the connecting slider, two rotating rods rotatably connected between the inner walls of the fixed bracket, two cutting blades fixedly installed on the outer walls of the two rotating rods respectively, the cutting blades being a spiral design, one end of the two rotating rods penetrating one side of the fixed bracket and fixedly connected to two linkage wheels respectively, the two linkage wheels being sleeved with belts, an output motor fixedly installed on the other side of the fixed bracket, the output end of the output motor being connected to one of the rotating rods.

[0005] As a further embodiment of this utility model: two limiting blocks are fixedly connected to both sides of the connecting slider, the limiting blocks are designed in the form of a T, and two limiting grooves are opened on both sides of the support bracket, with the two limiting blocks passing through the two limiting grooves respectively.

[0006] As a further embodiment of this utility model: two suction heads are symmetrically fixed on one side of the fixed bracket, the suction heads penetrate one side of the fixed bracket, the positions of the two suction heads correspond to the positions of the two cutting blades, and one end of each of the two suction heads is fixedly connected to two first connecting tubes.

[0007] As a further embodiment of this utility model: a suction pump is fixedly installed above the base plate, and the other ends of the two first connecting pipes are respectively connected to the two sides of the suction pump.

[0008] As a further embodiment of this utility model: a second connecting pipe is fixedly connected to one side of the suction pump, and a connecting bracket is fixedly installed above the base plate. The connecting bracket has an open design, and the second connecting pipe passes through one side of the connecting bracket.

[0009] As a further embodiment of this utility model: two connecting blocks are fixedly installed on the top of the connecting bracket, and the two connecting blocks are symmetrically distributed about the center of the connecting bracket.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This small watershed management river silt removal device, through the setting of a fixed support, rotating rods, cutting blades, linkage wheels, and belts, uses an output motor to drive one of the rotating rods to rotate during silt removal work. As the rotating rod rotates on the inner wall of the fixed support, its other end drives one of the linkage wheels to rotate. The two linkage wheels rotate synchronously under the action of the belt, so that the two rotating rods rotate synchronously. The two rotating rods drive the two cutting blades on their outer walls to rotate, cutting and shredding weeds or aquatic plants on the water surface. In this way, weeds and aquatic plants on the water surface can be effectively cut and shredded, avoiding damage to the device while improving silt removal efficiency.

[0012] 2. This small watershed management river silt removal device, through the setting of a support bracket, a support screw, a connecting slider, a control motor, and a fixed bracket, allows the control motor to drive the support screw to rotate between the inner walls of the support bracket during silt removal. The rotation of the support screw causes the connecting slider to move vertically within the support bracket, which in turn moves the fixed bracket vertically, thereby controlling the height of the two cutting blades. In this way, the height of the two cutting blades can be adjusted according to different water depths to achieve better cutting results and improve the practicality of the device.

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] like Figure 1-4 As shown, this utility model provides a technical solution: a river silt cleaning device for small watershed management, including a base plate 1, a suction pump 16 fixedly installed on the top of the base plate 1, the other ends of two first connecting pipes 15 respectively connected to both sides of the suction pump 16, a second connecting pipe 17 fixedly connected to one side of the suction pump 16, a connecting bracket 18 fixedly installed on the top of the base plate 1, the connecting bracket 18 is an open design, the second connecting pipe 17 passes through one side of the connecting bracket 18, and two connecting blocks 19 are fixedly installed on the top of the connecting bracket 18. The two connecting blocks 19 are symmetrically distributed about the center of the connecting bracket 18. Because of the connecting blocks 19, the device can be easily connected to other equipment or transportation tools through the connecting blocks 19, which facilitates movement and use in different work locations.

[0020] A support bracket 2 is fixedly installed on the upper part of the base plate 1 near its side. A support screw 3 is rotatably connected between the inner walls of the support bracket 2. The support screw 3 is designed vertically, and a connecting slider 4 is threadedly connected to the outer wall of the support screw 3. Through the cooperation between the support screw 3 and the connecting slider 4, the support screw 3 drives the connecting slider 4 to move in the vertical direction during rotation. This allows the position of the two cutting blades 8 to be adjusted through the fixed bracket 6, making it convenient to adjust the height of the cutting blades 8 according to the height of weeds or aquatic plants. Two limiting blocks 12 are fixedly connected to both sides of the connecting slider 4. The limiting blocks 12 are designed in T shape. Two limiting grooves 13 are opened on both sides of the support bracket 2. The two limiting blocks 12 pass through the two limiting grooves 13 respectively. Through the cooperation between the limiting blocks 12 and the limiting grooves 13, the connecting slider 4 drives the limiting blocks 12 on both sides to slide in the two limiting grooves 13 during sliding, ensuring the stability of the connecting slider 4 during movement, and thus ensuring the stability of the movement of the fixed bracket 6 and the cutting blades 8.

[0021] A control motor 5 is fixedly installed at the top of the support bracket 2. The output end of the control motor 5 is connected to one end of the support screw 3. A fixed bracket 6 is fixedly connected to one side of the connecting slider 4. Two rotating rods 7 are rotatably connected between the inner walls of the fixed bracket 6. Cutting blades 8 are fixedly installed on the outer walls of the two rotating rods 7 respectively. The cutting blades 8 are spiral-shaped. Because of the cutting blades 8, when dredging is carried out, the output motor 11 drives one of the rotating rods 7 to rotate. The rotating rod 7 drives the other rotating rod 7 to rotate through the linkage wheel 9 and the belt 10. The rotation of the two rotating rods 7 drives the cutting blades 8 on their outer walls to rotate. The cutting blades 8 are spiral-shaped, which can effectively cut and break up the silt and weeds in the river channel, thereby improving the cleaning efficiency.

[0022] One end of each of the two rotating rods 7 passes through one side of the fixed bracket 6 and is fixedly connected to two linkage wheels 9. The two linkage wheels 9 are fitted with belts 10. An output motor 11 is fixedly installed on the other side of the fixed bracket 6. The output end of the output motor 11 is connected to one of the rotating rods 7. Two suction heads 14 are symmetrically fixed on one side of the fixed bracket 6. The suction heads 14 pass through one side of the fixed bracket 6. The positions of the two suction heads 14 correspond to the positions of the two cutting blades 8. One end of each suction head 14 is fixedly connected to two first connecting pipes 15. Through the cooperation of the suction heads 14 and the suction pump 16, since the positions of the suction heads 14 correspond to the positions of the cutting blades 8, the suction heads 14 can timely suck up the silt and weeds after cutting and breaking them under the action of the suction pump 16. The silt and weeds are transported through the first connecting pipe 15 and the second connecting pipe 17, avoiding the situation where silt and weeds are missed during cleaning.

[0023] The working principle of this utility model is as follows: When using the device, the transport vehicle moves it to the river channel to be treated via the connecting block 19 above the connecting bracket 18. The control motor 5 drives the support screw 3 to rotate. During the rotation of the support screw 3, the connecting slider 4 drives the fixed bracket 6 to move in the vertical direction, thereby adjusting the height of the two cutting blades 8 so that the height of the two cutting blades 8 matches the height of the river channel. The output motor 11 drives one of the rotating rods 7 to rotate. During the rotation of the rotating rod 7, its other end drives the other rotating rod 7 to rotate through the cooperation of the linkage wheel 9 and the belt 10. The two rotating rods 7 drive the two cutting blades 8 to rotate between the inner walls of the fixed bracket 6, cutting and crushing the weeds or aquatic plants above the water surface. During the crushing process, the suction pump 16 transports the cut and crushed silt and weeds through the suction head 14 to the second connecting pipe 17 through the first connecting pipe 15. Then, the suction silt and weeds are collected through the output end of the second connecting pipe 17 for use in the device.
