The water weeds can enter the filter bucket structure after being cut, and the arc-shaped grille structure formed by the transverse bars 2 and the longitudinal bars 3 can quickly filter out water. On the one hand, it reduces the resistance to water weed cleaning, and on the other hand, it avoids disturbing the water weeds, thereby improving the water weed cleaning effect of the farmland water channel.

[0020] In this embodiment, in order to realize the lateral telescopic adjustment of the transverse adjustable bar 22, transverse sliding holes 211 are arranged inside the two ends of the transverse fixed bar 21, and the transverse adjustable bar 22 is slidably connected in the transverse sliding holes 211 in a fixed manner. Specifically, the positioning of the transverse adjustable bar 22 can be fixed by a set screw or a connecting screw arranged on the transverse fixed bar 21.

When the length of the connecting rod increases, the two groups of moving knife groups 42 move away from each other, and the overlapping area decreases, thereby increasing the cutting amplitude of the bottom surface of the filter bucket structure inlet. When the length of the connecting rod decreases, the two groups of moving knife groups 42 move closer to each other, and the overlapping area increases, thereby realizing the dynamic adjustment of the cutting amplitude of the bottom surface water grass cutting knife mechanism 4. Specifically, the first plug rod 442, the second plug rod 444 and the sleeve rod 443, one end of the first plug rod 442 is connected to the crank 441, and the other end is plugged into the sleeve hole at one end of the sleeve rod 443 in a fixed manner, and one end of the second plug rod 444 is connected to the moving knife group 42, and the other end is plugged into the sleeve hole at the other end of the sleeve rod 443 in a fixed manner.

The lower side of the fixed knife groove 432 of the fixed knife 431 is fixedly connected to the cutting knife frame 41, and the upper side is suspended, thereby ensuring that the fixed knife 431 maintains a certain elasticity when cooperating with the movable knife 421 for cutting. The movable knife 421 is a triangular structure, and grooves 422 are provided on the cutting edges inclined on both sides, thereby improving the cutting efficiency, and the cut aquatic plants will naturally enter the filter bucket structure.

[0024] In this embodiment, see Figure 8-Figure 10The hydraulic motor assembly 8 includes a hydraulic motor 81, a quick-locking bolt 82, and a base 83 that can be connected to different attachments. The base 83 is a universal base. The base 83 is provided with a mounting side plate 831. The mounting side plate 831 is provided with a side plate connecting hole 8311 connected to the motor mounting hole 811 of the hydraulic motor 81. The center of the mounting side plate 831 is provided with a motor output shaft extension hole 8312. The output shaft of the hydraulic motor 81 extends from the motor output shaft extension hole 8312 and is connected to the gears, couplings, cams and other transmissions on the attachment. The quick locking bolt 82 includes a handle nut 821, a locking plate 822, a locking plate driving rod 823, and a bolt rod 824 that can be inserted into the motor mounting hole 811 and the side plate connecting hole 8311. The handle nut 821 is threadedly connected to the outer wall of one end of the bolt rod 824, the locking plate driving rod 823 is slidably connected to the inner hole 8241 of the bolt rod 824, and the locking plate 822 is hinged to the side wall hole 8242 at the other end of the bolt rod 824 and is driven to rotate in and out of the side wall hole 8242 by the locking plate driving rod 823. Thus, it plays a limiting role, and then cooperates with the handle nut 821 to lock, and the hydraulic motor 81 is installed and fixed on the mounting side plate 831. When the bolt rod 824 of the present invention is inserted into the motor mounting hole 811 and the side plate connecting hole 8311, the locking plate 822 rotates inward. After being inserted into the motor mounting hole 811 and the side plate connecting hole 8311, the locking plate 822 rotates outward, driving the handle nut 821 to rotate, thereby reducing the distance between the handle nut 821 and the locking plate 822, and then the hydraulic motor 81 is firmly installed on the mounting side plate 831. The entire process only requires manual tightening, which is fast and efficient. At the same time, it also avoids the problem of hydraulic oil leakage caused by disassembling the hydraulic pipeline, avoids the waste of hydraulic oil and pollution of farmland water channels. Further, by disassembling the hydraulic motor 81, the hydraulic motor 81 can be used universally on different accessories.

[0025] In this embodiment, see Fig.10 In order to facilitate pressing the locking plate driving rod 823, the quick locking bolt 82 also includes a bolt handle 825 connected to one end of the bolt rod 824. The bolt handle 825 includes an index finger hook plate 8251 and a middle finger hook plate 8252 arranged on both sides to cooperate with the index finger and the middle finger respectively. The index finger hook plate 8251 and the middle finger hook plate 8252 are C-shaped structures, which are ergonomic and convenient for pressing the locking plate driving rod 823 downward to immerse the locking plate 822 into the side wall hole 8242.

[0026] In this embodiment, the locking plate 822 includes a locking paddle 8221 and a locking wing 8222 which are vertically integrated. The locking paddle 8221 and the locking wing 8222 are L-shaped as a whole. The locking wing 8222 is hinged to the side wall hole 8242. The other end of the locking plate driving rod 823 is provided with a convex ring 8231 for driving the locking paddle 8221 to reciprocate. When the convex ring 8231 moves downward, the locking wing 8222 is driven to swing inward, and then into the side wall hole 8242, so that the bolt rod 824 can be inserted into the motor mounting hole 811 and the side plate connecting hole 8311. When the convex ring 8231 moves upward, the locking wing 8222 is driven to swing outward, and then outside the side wall hole 8242, so that there is space for the locking wing 8222 and the handle nut 821 to limit the travel.

[0027] In this embodiment, in order to make the locking wing 8222 automatically pop outward, the quick locking bolt 82 further includes a locking spring 826 disposed in the inner hole 8241 of the bolt rod 824. One end of the locking spring 826 abuts against the bottom of the inner hole 8241, and the other end abuts against the convex ring 8231 to keep the end of the locking wing 8222 protruding from the side wall hole 8242. The locking wing 8222 can then be clamped against the outer edge of the pressure motor mounting hole 811, playing a role of connection and limiting. During operation, the locking plate driving rod 823 is pressed downward to drive the locking paddle 8221, the locking spring 826 contracts, and the locking wing 8222 rotates counterclockwise to enter the side wall hole 8242, so that the bolt rod 824 can be inserted into the motor mounting hole 811 and the side plate connecting hole 8311. After insertion and positioning, the bolt handle 825 is released, and the convex ring 8231 moves upward under the drive of the locking spring 826, and the locking wing 8222 rotates clockwise to extend out of the side wall hole 8242 to form a limiting step structure. At this time, the handle nut 821 can be rotated to lock.

[0028] In this embodiment, in order to make the handle nut 821 a labor-saving structure and facilitate manual locking of the hydraulic motor 81, the handle nut 821 includes a nut body 8211 and a plurality of rotating rods 8212 arranged axially along the nut body 8211, one end of each rotating rod 8212 is fixedly connected to the nut body 8211, and the other end extends radially outward along the nut body 8211, forming a scattered shape structure, similar to a sailing steering wheel.

[0029] In this embodiment, a slide rail slider assembly 84 and a bottom plate 85 mounted on the slide rail slider assembly 84 are also installed on the base 83. The hydraulic motor 81 is installed on the bottom plate 85. The sliding direction of the bottom plate 85 is parallel to the axis of the motor output shaft extension hole 8312. Therefore, the hydraulic motor 81 can be pre-installed outside the motor output shaft extension hole 8312 to avoid the high difficulty and low efficiency of manual centering. After pre-installation, it can be pushed toward the motor output shaft extension hole 8312 to reach the pre-positioned position. In this embodiment, a positioning plate 832 is provided on one side of the mounting side plate 831. A plurality of bottom plate positioning assemblies 86 are installed on the positioning plate 832. The bottom plate positioning assemblies 86 include a positioning rod 861 that is slidably connected to the positioning plate hole 8321 of the positioning plate 832. The positioning rod 861 matches the bottom plate hole 851 on the bottom plate 85. Therefore, the hydraulic motor 81 is pre-positioned, which is convenient for the subsequent fast locking bolt 82 to be locked.

[0030] In this embodiment, in order to improve the efficiency of pre-positioning, the bottom plate positioning assembly 86 further includes a lever 862 and a return spring 863. The lever 862 is connected to the bottom of the positioning rod 861. One end of the return spring 863 is connected to the positioning plate 832, and the other end is connected to the lever 862. Thus, the positioning rod 861 can realize the function of automatic reset. When working, the lever 862 is pulled downward, and the positioning rod 861 withdraws from the bottom plate hole 851. At this time, the bottom plate 85 can be withdrawn. After the lever 862 is released, the positioning rod 861 is reset upward under the action of the spring.

[0031] In this embodiment, in order to improve the efficiency of pre-installing the hydraulic motor 81 outside the motor output shaft extension hole 8312, a longitudinal fixing block 87 is also included. The longitudinal fixing block 87 is installed on the bottom plate 85, and a plug-in cavity matching the shape of the hydraulic motor 81 is provided on the longitudinal fixing block 87. When the hydraulic motor 81 is inserted into the plug-in cavity, the output shaft of the hydraulic motor 81 can be aligned with the motor output shaft extension hole 8312.
