[0026] like Figure 1As shown, a river sludge collection device includes two sludge collection vehicles 1 that move along the river banks on both sides of the river, a support frame 4 that is detachably arranged between the two sludge collection vehicles 1, and a sludge suction mechanism arranged in the middle of the support frame 4. The sludge suction mechanism includes a collection bucket 15 that is horizontally rotatable and arranged on the support frame 4, a plurality of sludge suction components that are evenly arranged on the outer circumference of the collection bucket 15, and a drilling component that is arranged at the bottom end of the collection bucket 15. The top end of the collection bucket 15 is connected to the drilling drive motor 10 fixed on the support frame 4, and the collection bucket 15 is also connected to the sludge collection vehicle 1.

[0027] It should be noted that the sludge collection vehicle 1 in this embodiment is an unmanned vehicle. Since its structure and working principle are common knowledge in the art, they will not be described in detail here.

[0028] Specifically, the sludge suction assembly includes an arcuate suction pipe 23 tangentially connected to the collection barrel 15. A horizontally rotatable suction impeller is installed within the collection barrel 15, corresponding to the position of the arcuate suction pipe 23. The suction impeller is connected to the suction drive motor 14 fixed to the top outer wall of the collection barrel 15. The arcs of the multiple arcuate suction pipes 23 are curved in the same direction. The ends of the arcuate suction pipes 23 away from the collection barrel 15 are connected to trumpet-shaped suction ports 22, which are distributed along the same circumference.

[0029] The drilling assembly includes a tapered shaft 20 fixed to the bottom end of the collecting barrel 15 via a buffer component and a spiral drilling blade 18 fixed to the outer circumference of the tapered shaft 20; the bottom end of the tapered shaft 20 is set to a pointed head, and a rotating ball 19 is rotatably set on the pointed head. The setting of the rotating ball 19 facilitates walking along the riverbed.

[0030] The buffer component includes an outer cylinder 21 fixed to the bottom end of the collecting barrel 15 and an inner cylinder 17 vertically slidingly arranged at the bottom end of the outer cylinder 21. A buffer spring is arranged between the outer cylinder 21 and the inner cylinder 17. The bottom end of the inner cylinder 17 is fixedly connected to the top end of the tapered shaft 20. By arranging the buffer spring, the impact of the tapered shaft 20 on the river bottom and the tapered shaft 20 caused by the descent of the river bottom can be buffered, and at the same time, it is easy to adapt to the uneven terrain of the river bottom.

[0031] A hollow rotating shaft 11 is fixed to the top of the collecting bucket 15, and the top of the hollow rotating shaft 11 is fixedly connected to the center of the driven sprocket 7 via a lifting drive hydraulic cylinder 12. The collecting bucket 15 in this embodiment is also provided with a guide shaft 13 for vertical sliding. The top of the guide shaft 13 is fixedly connected to the driven sprocket 7. By setting the lifting drive hydraulic cylinder 12, it can adapt to different riverbed heights. The driven sprocket 7 is horizontally rotated and set at the top of the support frame 4, and the driven sprocket 7 is connected to the drilling drive motor 10 in turn via the drive chain 8 and the active sprocket 9; the top of the hollow rotating shaft 11 is also connected to the main pipe 6 via a sealed bearing, and the main pipe 6 is connected to the sludge collection vehicle 1 via a tee pipe and a branch pipe 2 in turn. A sewage suction pump 5 is provided on the branch pipe 2. In this embodiment, the branch pipe 2 is overlapped at the top of the support seat 3, and the support seat 3 is fixed on the support frame 4.

[0032] A two-position three-way valve is provided in the three-way pipe, the two-position three-way valve is connected to a controller, and the controller is connected to a timer, thereby realizing alternate injection of sludge into the two sludge collection vehicles 1 .

[0033] A plurality of centrifugal water outlet holes 16 are provided on the side wall of the collecting barrel 15 , so that when the collecting barrel 15 rotates, the excess water can be thrown out through the centrifugal water outlet holes 16 .

[0034] The above structure realizes the following working process: first, the sludge collection vehicle 1 is driven to the area to be cleaned, the lifting drive hydraulic cylinder 12 is opened, and the conical shaft 20 is observed until it is inserted into the silt and the rotating ball 19 reliably contacts the riverbed. The sewage suction pump 5, the drilling drive motor 10 and the suction drive motor 14 are turned on. The drilling drive motor 10 drives the driven sprocket 7 to rotate through the driving sprocket 9 and the driving chain 8 in turn, and then drives the collection bucket 15 and the conical shaft 20 to rotate through the hollow rotating shaft 11. During the rotation of the conical shaft 20, the auger is used to The blade 18 is used to cut the silt layer, and the solidified silt layer is fluffed. Then, under the action of the suction drive motor 14, the sludge is sucked into the collection barrel 15 through the trumpet-shaped suction port 22. Then, under the action of the sewage suction pump 5, the sludge in the collection barrel 15 is injected into the two sludge collection vehicles 1 in time periods through the hollow rotating shaft 11, the main pipe 6 and the branch pipe 2 until the cleaning is completed. The tapered shaft 20 is lifted by the lifting drive hydraulic cylinder 12, and then the whole is lifted away from the river bank. Finally, the sludge collection vehicle 1 is dismantled, and the internal sludge is poured out for unified treatment.

[0035] It should be noted that the above-mentioned electronic components are mature products on the market. This embodiment only needs to purchase them and connect them according to the instructions. No improvement is made to them, so their circuit connection structure and principles will not be described in detail here.

[0036] Therefore, the present invention adopts the river sludge collection device of the above structure, and can use the sludge collection vehicle to move along the river bank, and use the drilling component to dig sludge during the movement, and use the sludge suction component to suck the dug sludge into the collection bucket, after throwing out the excess water, collect it into the sludge collection vehicle through the hollow rotating shaft, thereby realizing efficient sludge collection operation.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the same. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solutions of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
