Technical Field
[0001] The utility model relates to the technical field of grass cutting tools, in particular to a tool for a grass cutting and dicing machine. Background Art
[0002] A dicer is a machine that processes whole materials into dices. A lawn mower, on the other hand, cuts grass. If the long stalks left behind by a lawn mower are too long, they are typically incinerated. This produces large amounts of smoke and dust, which seriously pollutes the air. The carbon dioxide emitted by combustion increases atmospheric CO2 levels, exacerbating the greenhouse effect. This runs counter to environmental requirements for reducing CO2 emissions. To avoid this, the grass stalks need to be cut and shortened. A dicer, on the other hand, breaks them into smaller pieces for easier use.
[0003] The publication (announcement) number is CN220108723U, which discloses a dual-purpose grass cutting and dicing machine, relating to the technical field of grass cutting machinery. The utility model includes a support mechanism, including a plurality of support rods and a connecting rod provided between two support rods; a cutting mechanism, which is provided on the support mechanism, including a drive assembly provided within the support mechanism and a cutting assembly provided at one end of the drive assembly, the drive assembly including a drive motor and a rotating shaft connected to the output end of the drive motor, and the cutting assembly including a cutting shaft and a plurality of dicing knives and a plurality of grass cutting knives provided outside the cutting shaft. The utility model is a dual-purpose grass cutting and dicing machine, in which the driving motor drives the rotating shaft to rotate, the driving wheel rotates accordingly, and the transmission belt installed thereon drives the driven wheel to rotate, providing power for the rotation of the cutting shaft, thereby ensuring that the dicing knives and the grass cutting knives can both rotate quickly, so that grass cutting and dicing can be performed together to form an integrated machine.
[0004] Although the above scheme can realize the cutting and dicing of grass stalks, the number of cutting and dicing tools is large, and it is difficult and laborious to disassemble and maintain them. In addition, the cutting method of the tools is limited. Therefore, we propose a tool for a grass cutting and dicing machine. Utility Model Content

[0007] The two ends of the guide rail are fixedly mounted on the support frame, and the two ends of the guide rail are fixedly mounted on the support frame, and the two ends of the guide rail are fixedly mounted on the support frame.
[0008] The tool component includes an arc-shaped plate, a mounting block, a fixing bolt and a double-edged blade plate. A arc-shaped plate is fixedly provided on the end face of each plug-in block, and the arc-shaped plate surrounds the outer circumference of the bearing cylinder. Every three mounting blocks form a group and are fixedly provided on the outer circumference of the arc-shaped plate at equal intervals. The fixing bolt is movably provided on the mounting block. The double-edged blade plate is sleeved on the fixing bolt and fixed by a nut. The double-edged blade plate is in an "L" shape and its corner part is inclined.

[0014] Compared with the prior art, the present invention provides a tool for a grass cutting and dicing machine, which has the following beneficial effects:
[0015] 1. In the present invention, by providing a positioning unit, when the arc plate is placed around the outer circumference of the carrying cylinder, a plurality of plug-in blocks can extend one by one into the interior of the carrying cylinder and reach between the two strip carriers through the plug-in notches. By holding the outside of the carrying cylinder and rotating the bidirectional screw rod forward and backward, two of the guide blocks threadedly connected to the bidirectional screw rod are subjected to force and move relative to each other, which can help the two strip carriers to adjust the spacing inside the carrying cylinder. The other three groups of guide blocks can slide and translate on the three guide rods respectively to cooperate with the strip carriers to mobilize and provide auxiliary support for them. After the two strip carriers are close to each other, all locking blocks can be tightly inserted into the locking grooves on the opposite side surfaces of the plug-in blocks. All tool components are synchronously locked on the carrying cylinder. The reverse operation can remove all tool components as a whole. The equipment is simple and labor-saving for the overall disassembly and maintenance of a large number of grass cutting and dicing tools.
