[0022] 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.

[0023] like Figure 1 As shown, a chaff cutter for a no-till planter includes a mounting plate 1 and a blade body 3. The mounting plate 1 is provided with a connector for connecting the cutter disc by plugging in. The blade body 3 is fixedly connected to the edge of the mounting plate 1 and is inclined toward a first side of the mounting plate 1. An extension 5 is integrally connected to the part of the blade body 3 away from the mounting plate 1. The extension 5 is inclined toward a second side of the mounting plate 1 or parallel to the mounting plate 1.

[0024] This utility model's chaff cutter is applicable to no-till planters, such as the 2BMQF-5 / 10 no-till planter produced by the applicant, Luoyang Xinle Machinery Equipment Co., Ltd. This model of no-till planter can be used for no-till fertilization sowing of various crops such as wheat, corn, soybeans, and sorghum. In the chaff cutter, the mounting plate 1 can be installed onto the cutter disc via a plug-in connector, making installation and disassembly easier. Because the cutter body 3 is inclined towards the first side of the mounting plate 1, after connection, the cutter body 3 will tilt to the side of the cutter disc, and the cutter body 3 is also inclined relative to the soil surface. Therefore, during the operation of the no-till planter, the cutter disc can drive the cutter body 3 to rotate, thereby using the cutter body 3 to chop and separate straw and roots in the seedling strip. At the same time, the cutter body 3 can also penetrate into the soil to achieve the functions of ditching and soil breaking. Furthermore, by connecting the extension 5 to the part of the blade 3 away from the mounting plate 1, and by making the extension 5 inclined relative to the blade 3 toward the second side of the mounting plate 1 or parallel to the mounting plate 1, the extension 5 is nearly perpendicular to the soil surface. During the rotation of the blade 3, the extension 5 can better penetrate into the soil and better perform the functions of trenching and soil breaking.

[0025] Three different connectors are provided below.

[0026] The first type of connector has the following structure: at least two through holes 6 are provided on the mounting plate 1, the connector includes at least two connecting posts 2 that pass through the through holes 6, and the connecting posts 2 extend to the second side of the mounting plate 1.

[0027] like Figures 1 to 3 As shown, the first type of connector is suitable for upgrading and modifying the disc guillotine cutting tool produced based on Chinese Patent Application No. 201430170052.4. By adding a connecting post 2 in the through hole 6, the mounting plate 1 and the cutter head can be connected by plugging in the connecting post 2. The connecting post 2 and the mounting plate 1 can be fixedly connected by welding.

[0028] Furthermore, a receiving groove 7 is provided on the first side of the mounting plate 1, and the receiving groove 7 is connected to all the through holes 6. All the connecting posts 2 are fixedly connected to a positioning plate 8, which is inserted into the receiving groove 7. Based on this structure, the connecting posts 2 can be welded to the positioning plate 8 first, then the positioning plate 8 can be placed into the receiving groove 7, and then the positioning plate 8 can be welded to the mounting plate 1 for fixation. The connecting posts 2 can also be welded to the mounting plate 1 for fixation, thus completing the installation of the connecting posts 2. Based on this structure, there are more welding connection points, and the stability of the connecting posts 2 is stronger.

[0029] The second type of connector has the following structure: the connector includes a connecting plate 9 that is fixedly connected to the mounting plate 1. The connecting plate 9 is located on the second side of the mounting plate 1 and is perpendicular to the mounting plate 1.

[0030] like Figure 4 As shown, the second type of connector is suitable for remanufacturing without the existing disc guillotine cutting tool. For ease of production, the connecting plate 9 and the mounting plate 1 are integrally connected via an arc-shaped transition portion 10. During production, the connecting plate 9 and the transition portion 10 are formed by heating and bending the mounting plate 1, without the need for additional welding, resulting in higher production efficiency.

[0031] like Figure 5 As shown, the third type of connector has the following structure: the connector includes a first bonding plate 11 that adheres to the second side of the mounting plate 1. Additionally, the connector includes two second bonding plates 13 that adhere to the first side of the mounting plate 1, and the second bonding plates 13 are fixedly connected to the first bonding plates 11 via connecting plates 12. In the production process, the first bonding plates 11, connecting plates 12, and second bonding plates 13 are first manufactured to form independent connectors. Then, the mounting plate 1 is inserted into the gap between the first bonding plates 11 and the second bonding plates 13, and then the first bonding plates 11, connecting plates 12, and second bonding plates 13 are welded and fixed to the mounting plate 1. For ease of production, the first bonding plates 11, connecting plates 12, and second bonding plates 13 are integrally connected.

[0032] It should also be noted that, based on the three types of connectors mentioned above, in order to achieve the insertion connection between the cutter head and the grooving blades, insertion holes need to be made on the cutter head. The shape of the insertion holes matches the shape of the connecting post 2, connecting plate 9, or first bonding plate 11 mentioned above. In addition, after all the grooving blades are inserted and connected to the cutter head, the mounting plate 1 can be pressed tightly onto the cutter head by a pressure cap. The pressure cap can be connected to the cutter head by bolts. Compared with the method of connecting each grooving blade by at least two bolts, using only bolts to connect the pressure cap and the cutter head can significantly reduce the number of bolts used.

[0033] Furthermore, among the three types of connectors mentioned above, the first type is suitable for upgrading and modifying existing disc guillotine cutting tools produced based on Chinese patent application number 201430170052.4. The second and third types are suitable for re-production. The second type of connector is easier to produce and has higher production efficiency, but the transition part 10 will occupy a certain space, making it impossible for the mounting plate 1 to fit tightly against the cutter head. It is necessary to weld additional pads onto the cutter head to fit and support the mounting plate 1. Compared with the second type of connector, the third type of connector has a more complex structure and production process, but the mounting plate 1 can fit against the cutter head without the need for additional pads. In actual implementation, the three types of connectors mentioned above can be flexibly selected according to the actual situation.

[0034] Furthermore, the blade 3 is trapezoidal in shape, with the larger end of the blade 3 integrally connected to the edge of the mounting plate 1, and the extension 5 integrally connected to the smaller end of the blade 3. Both sides of the blade 3 are provided with cutting edges 4 to facilitate better chopping and separating of straw and roots in the planting seedling strip.

[0035] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
