The pin is inserted into the through hole and the through hole.

[0007] Furthermore, there are multiple through holes, and each through hole is distributed at intervals along the height direction of the resistance tillage blade.

[0008] Furthermore, the width of the second opening is greater than the width of the resistance tillage blade.

[0009] Furthermore, the connector includes two side plates arranged in parallel and an abutment portion for connecting the two side plates, the abutment portion being integrally formed with the two side plates.

[0010] Furthermore, the cross-section of the side plate is L-shaped.

[0011] The beneficial effects of this utility model are as follows: Compared with the prior art, the resistance tillage device of this utility model can be connected to external agricultural machinery by setting a tillage connecting plate; the resistance tillage blade can be installed on the tillage connecting plate by setting a connecting member; the connecting member has an abutment part and a first opening for the tillage connecting plate to be inserted, so that the resistance tillage blade can be clamped by the tillage connecting plate and the abutment part, thereby realizing the control of the tillage depth and speed of crops; by setting an avoidance notch on the connecting member and rotating the resistance tillage blade on the connecting member through a pin, when the agricultural machinery moves backward, the resistance tillage blade will rotate along the pin after being subjected to force, so that the resistance tillage blade will leave the ground, effectively preventing the danger of side tipping or back tipping when the agricultural machinery moves backward.

[0023] like Figures 1 to 4 As shown, this embodiment proposes a resistance tillage device, including a tillage connecting plate 1, a resistance tillage blade 2, and a connector 3. The tillage connecting plate 1 is connected to agricultural machinery. The connector 3 is used to install the resistance tillage blade 2 on the tillage connecting plate 1. In addition, the resistance tillage blade 2 is rotatably mounted on the connector 3 via a pin 4. The connector 3 is provided with an abutment portion 32, which can be used to abut the resistance tillage blade 2 when the agricultural machinery moves forward. The connector 3 has a first opening 31, which allows the tillage connecting plate 1 to be inserted to cooperate with the abutment portion 32 to clamp the resistance tillage blade 2. In addition, the connector 3 also has an avoidance notch 33, which can be used to provide avoidance space for the rotation of the resistance tillage blade 2 when the agricultural machinery moves backward. In this way, by setting the blade connecting plate 1, it can be connected to external agricultural machinery; by setting the connecting piece 3, the resistance blade 2 can be installed on the blade connecting plate 1; the connecting piece 3 has an abutment part 32 and a first opening 31 for the blade connecting plate 1 to be inserted, so that the blade connecting plate 1 and the abutment part 32 can cooperate to clamp the resistance blade 2, thereby controlling the tillage depth and tillage speed of the crops; by setting an avoidance notch 33 on the connecting piece 3, and rotatably installing the resistance blade 2 on the connecting piece 3 via the pin 4, when the agricultural machinery moves backward, the resistance blade 2 will rotate along the pin 4 after being subjected to force, so that the resistance blade 2 will leave the ground, effectively preventing the danger of the agricultural machinery easily tipping over or overturning when moving backward.

[0024] Preferably, please refer to Figure 1 As shown, the blade connecting plate 1 is perpendicular to the resistance blade 2. Thus, when the resistance blade 2 is in operation, one side of the resistance blade 2 abuts against the contact part 32, and the other side of the resistance blade 32 abuts against the blade connecting plate 1, thereby clamping the resistance blade 2 and meeting operational requirements.

[0025] Preferably, please refer to the following: Figure 1 and Figure 3 As shown, the blade connecting plate 1 is positioned above the abutment portion 32. This arrangement serves two purposes: firstly, it allows for the clamping of the resistance blade 2; secondly, it facilitates the rotation of the resistance blade 2 when the agricultural machinery is reversing, preventing the machinery from tipping over.

[0026] Further, please refer to Figure 3As shown, the connector 3 also has a second opening 34, which allows the resistance tiller 2 to be inserted. This makes the entire resistance tiller device more compact and reduces space occupation. Furthermore, the resistance tiller 2 has a through hole 21, and the two side walls of the second opening 34 have through holes 36, into which the pin 4 can be inserted. This allows the connector 3 and the resistance tiller 2 to be rotatably connected via the pin 4.

[0027] Furthermore, there are multiple through holes 21, which are spaced apart along the height direction of the resistance tillage blade 2. By setting multiple through holes 21, the installation position of the resistance tillage blade 2 can be adjusted according to different tillage depth requirements, allowing for operations at different depths and meeting various user needs.

[0028] Preferably, the width of the second opening 34 is greater than the width of the resistance tillage blade 2, which facilitates the insertion of the resistance tillage blade 2 and also facilitates the rotation of the resistance tillage blade 2.

[0029] Further, please refer to Figure 4 As shown, the connector 3 includes two parallel side plates 35 connected by an abutment portion 32. Specifically, the abutment portion 32 is integrally formed with the two side plates 35. In this way, the two side plates 35 clamp the resistance blade 2 and the blade connecting plate 1; and the integral formation of the abutment portion 32 with the two side plates 35 improves the overall bonding force of the connector 3, reduces subsequent machining, and lowers processing costs.

[0030] Preferably, the side plate 35 has an L-shaped cross-section. Of course, in this embodiment, the cross-section of the side plate 35 may also have other shapes depending on the actual situation and specific needs, and is not limited to one shape here.

[0031] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
