A motor, a drive gear, a transmission gear and an output gear are installed above the bucket, and the motor drives the left auger and the right auger to rotate and crush the silt.
[0006] Furthermore, a sealing ring and a gearbox are also installed on the back of the bucket to protect the internal gears and bearings from corrosion.
[0007] Furthermore, one end of the right auger is provided with a right end cap, a right bearing cap, and a bearing for supporting the right auger.
[0008] Furthermore, the back of the bucket is also provided with an output shaft. The motor drives the drive gear, transmission gear and output gear to transmit to the output shaft. The output shaft drives the left cutter and the right cutter to rotate and crush the silt.
[0009] The beneficial effects of this utility model are:
[0010] The bucket of this utility model can collect silt and crush it by rotating the left and right cutters, which improves the processing efficiency and reduces pollution. In addition, the design of the left and right end covers and bearing covers provides support for the cutters, reduces wear on the device, and extends the device's lifespan.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figures 1-2 As shown, Figures 1-2 The diagram schematically illustrates a silt removal and collection device according to the present invention.
[0016] A silt cleaning and collection device includes a bucket 9, characterized in that a left cutter 8 and a right cutter 7 are symmetrically installed on the bucket 9, and a left end cover 1, a left bearing cover 2 and a bearing 15 are provided at one end of the left cutter 8 for supporting the left cutter 8. A motor 4, a drive gear 10, a transmission gear 11 and an output gear 13 are installed above the bucket 9, and the motor 4 drives the left cutter 8 and the right cutter 7 to rotate and crush the silt.
[0017] Among them, the bucket 9 acts as the "frame" of the entire device, playing a supporting role in the entire device.
[0018] This also includes waterproof components inside the device, which, together with the left bearing cover 2 and the bearing 15, effectively support the left auger 8 and protect the bearing from corrosion.
[0019] The left cutter 8 and the right cutter 7 operate in opposite directions, rotating and crushing up the silt to improve work efficiency.
[0020] Furthermore, a sealing ring 14 and a gearbox 3 are also installed on the back of the bucket 9 to protect the internal gears and bearings from corrosion.
[0021] The sealing ring 14 and the gearbox 3 form a sealed space to ensure that the gears and bearings are not corroded.
[0022] Furthermore, one end of the right auger 7 is provided with a right end cover 6, a right bearing cover 5, and a bearing for supporting the right auger 7.
[0023] The right auger 7 and related components have the same function as the left auger 8 and related components, only differing in their operating direction, and will not be described in detail here.
[0024] Furthermore, the back of the bucket 9 is also equipped with an output shaft 12. The motor 4 drives the drive gear 10, transmission gear 11 and output gear 13 to transmit to the output shaft 12. The output shaft 12 drives the left cutter 8 and the right cutter 7 to rotate and crush the silt.
[0025] The beneficial effects of this utility model are:
[0026] The bucket of this utility model can collect silt and crush it by rotating the left and right cutters, which improves the processing efficiency and reduces pollution. In addition, the design of the left and right end covers and bearing covers provides support for the cutters, reduces wear on the device, and extends the device's lifespan.
[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
