DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0021] Embodiment one

[0022] Please refer to Figure 1 and Figure 2 The present application provides a technical solution: the processing of silage forage grass is through the rotation of the cutter disc of the grass cutter driven by the motor or the internal combustion engine, so that the grass cutter contacts and cuts the forage grass in the process of high-speed rotation. After the forage grass is sent into the cutting area, it is sheared and extruded by the grass cutter and is cut into the required length. A grass cutter for silage forage grass includes a cutter body adapter block 100. One side of the cutter body adapter block 100 is provided with a grass cutter body 200. The cutter body adapter block 100 and the two sides of the grass cutter body 200 are symmetrically provided with fixed grooves 201. The fixed grooves 201 are provided with assembly fixing plates 204. The fixed grooves 201 are also provided with assembly fixing bolts 205. One side of the surface of the cutter body adapter block 100 is provided with an integrated rectangular embedded protruding block 203. The other side of the surface of the cutter body adapter block 100 is provided with a rectangular embedded clamping groove 202. When the grass cutter in the application is used to cut and process silage forage grass, after the cutter body adapter block 100 and the grass cutter body 200 are installed, the installation groove provided on the cutter body adapter block 100 is installed on the equipment, and then the grass is cut by rotating the equipment.

[0023] Specifically, the cutter body adapter block 100 and the grass cutting cutter body 200 are fixed symmetrically by assembling the fixing piece 204 and the fixing bolt 205 into the fixing groove 201, which ensures stable installation and improves the convenience of disassembly. The grass cutting cutter body 200 is provided with a corresponding rectangular embedded protrusion 203 and a rectangular embedded slot 202 on the cutter body adapter block 100, which better ensures the stability of the grass cutting cutter body 200 and prevents the grass cutting cutter body 200 from shaking during the cutting process. When installing the cutter body adapter block 100 and the grass cutting cutter body 200, or when replacing the grass cutting cutter body 200 after a period of use, the new grass cutting cutter body 200 is taken out, and the grass cutting cutter body 200 is provided with a rectangular embedded protrusion 203 and a rectangular embedded slot 202, which are correspondingly embedded with the rectangular embedded protrusion 203 and the rectangular embedded slot 202 on the cutter body adapter block 100. After stable installation, the assembling fixing piece 204 is inserted into the fixing groove 201 at both ends, and the assembling fixing bolt 205 is used for fixing. Through this fixing method, the assembly can be completed. When the grass cutting cutter body 200 has a gap or is damaged, only the grass cutting cutter body 200 needs to be replaced, without the need to replace the entire grass cutting cutter, saving cost and reducing waste of raw materials, thereby better serving the grass cutting use.

[0024] Example two

[0025] Please refer to Figure 1 、 Figure 2 and Figure 3 , the utility model provides a technical scheme: a silage grass cutting cutter, two U-shaped installation grooves are symmetrically arranged on the top of the cutter body adapter block 100, positioning cavities 301 are arranged at the two ends of the top of the cutter body adapter block 100, spring seats 302 are installed in the positioning cavities 301, reset springs 303 are arranged on the inner side of the spring seats 302, and auxiliary installation positioning rods 300 are arranged at one end of the reset springs 303 in the spring seats 302. In the process of fixing and installing the grass cutting cutter, in order to facilitate the positioning of the cutter body adapter block 100, when the installation grooves on the cutter body adapter block 100 are aligned with the installation bolts, the auxiliary installation positioning rods 300 on one side of the installation grooves can be inserted into the positioning rod insertion grooves 304 for limiting, so as to prevent the grass cutting cutter from falling during installation and affecting the installation efficiency. A section of the auxiliary installation positioning rod 300 is limited in the spring seat 302 and provides a reset force through the reset spring 303, so as to better limit and provide auxiliary function during installation, further improve the practicability of the device, and better install and fix.

[0026] Specifically, the auxiliary installation positioning rod 300 extends through the spring seat 302 and the positioning cavity 301 to the installation slot, facilitating the extension and retraction of the auxiliary installation positioning rod 300 in the limiting process. One side surface of the installation slot is provided with a corresponding positioning rod plug-in slot 304. When the cutter body matching block 100 is installed, the auxiliary installation positioning rod 300 is inserted into the positioning rod plug-in slot 304 for limiting auxiliary installation, better ensuring the convenience and stability during installation.

[0027] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
