Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery, and specifically relates to a crushing device with a crushing and anti-entanglement mechanism. Background Technology

[0002] The crushing device of a rotary tiller is a key component in agricultural machinery used to crush materials such as soil and straw. Its crushing blade is the main working part, so the durability of the crushing blade is the key to improving rotary tillage efficiency and reducing operating costs.

[0003] The existing crushing devices have gaps between the crushing blades. During rotary tillage, weeds can easily get tangled in the gaps and onto the blade shaft. Once weeds are tangled on the blade shaft, it is not conducive to the rotary tillage device. In addition, the gaps between the crushing blades cannot be tilled during rotary tillage, resulting in poor weed removal and soil tillage.

[0004] To address this, our company developed a crushing device with a crushing and anti-entanglement mechanism, which improves the rotary tillage efficiency of the crushing device. Utility Model Content

[0009] The beneficial effects of adopting the above-mentioned further technical solution are as follows: the cutting part is supported by the support part, so that the cutting part can quickly cut weeds or break the soil during the rotary tillage process; the uniform distribution of several crushing and anti-entanglement blades along the radial direction of the blade shaft can avoid the crushing and anti-entanglement blades from sinking, which is conducive to the efficient rotary tillage of the crushing device.

[0010] Furthermore, one end of the support and cutting parts is connected to the cutter shaft;

[0011] Preferably, the support part is in the shape of a straight plate or a bent plate, and the cutting part is a straight cutting edge;

[0012] Preferably, the bending direction of the support portion is radial bending along the cutter axis.

[0013] The beneficial effects of adopting the above-mentioned further technical solution are as follows: by connecting one end of the support part and the cutting part to the cutter shaft, one end of the crushing and anti-tangling blade is connected to the cutter shaft, and the other end of the crushing and anti-tangling blade breaks the soil or chops the grass first and then slowly enters the soil during the rotary tillage process; by making the support part straight or bent, and the cutting part straight cutting blade, the grass chopping working part can quickly enter the soil and cut weeds.

[0014] Furthermore, the end of the support and cutting parts away from the grass-chopping working part is provided with a fixed angle, which is less than 180°.

The crushing and anti-entanglement mechanism 2 is disposed between the gaps of adjacent crushing blade groups 1. By arranging a plurality of crushing blade groups 1 on the cutter shaft 3 and placing the crushing and anti-entanglement mechanism 2 between the crushing blade groups 1, weeds can be prevented from entangled on the cutter shaft 3 between the crushing blade groups 1. At the same time, the crushing and anti-entanglement mechanism 2 can cut the weeds in the gaps between the crushing blade groups 1 and perform rotary tillage on the soil in the gaps between the crushing blade groups 1.

[0046] The shredding and anti-tangling mechanism 2 includes a plurality of shredding and anti-tangling blades 21. Each shredding and anti-tangling blade 21 includes a grass-shredding working part 22, which includes a support part 221 and a cutting part 222. The support part 221 is connected to the cutting part 222. Preferably, the plurality of shredding and anti-tangling blades 21 of the shredding and anti-tangling mechanism 2 are evenly distributed radially along the blade shaft 3. The support part 221 supports the cutting part 222, enabling the cutting part 222 to quickly cut weeds or break up the soil during rotary tillage. The even distribution of the plurality of shredding and anti-tangling blades 21 radially along the blade shaft 3 can prevent the shredding and anti-tangling blades 21 from becoming uneven, which is beneficial for the shredding device to perform efficient rotary tillage.

[0047] One end of the support part 221 and the cutting part 222 is connected to the blade shaft 3; preferably, the support part 221 is a straight plate and the cutting part 222 is a straight cutting edge; more preferably, the bending direction of the support part 221 is radial along the blade shaft 3. By connecting one end of the support part 221 and the cutting part 222 to the blade shaft 3, one end of the shredding and anti-tangling blade 21 is connected to the blade shaft 3, and the other end of the shredding and anti-tangling blade 21 first breaks the soil or shreds grass and then slowly enters the soil during rotary tillage; by making the support part 221 a straight plate and the cutting part 222 a straight cutting edge, the grass-shredding working part 22 can quickly enter the soil and cut weeds;

[0048] The support portion 221 and the cutting portion 222 are provided with a fixed angle 223 at the end away from the grass-chopping working portion 22, and the fixed angle 223 is less than 180°.

By setting the connection of the anti-tangling crushing mechanism 2 perpendicular to the cutter shaft 3, the anti-tangling crushing mechanism 2 can more easily cut into the soil during rotary tillage, resulting in a more uniform crushing effect, reducing stress concentration, and improving the durability of the anti-tangling crushing mechanism 2. By staggering the anti-tangling crushing mechanism 2 along the axial direction of the cutter shaft 3, the rotary tillage range can be expanded, allowing it to cut into the soil from different angles, more efficiently crushing soil clods, making the time interval between blade cuts into the soil more uniform, which can offset the radial distribution of rotational centrifugal force, reduce the vibration of the cutter shaft 3, and the staggered anti-tangling crushing mechanism 2 can significantly improve the working quality, reliability, and environmental adaptability of the rotary tiller through mechanical balance and spatial coordination.

The buffer section 24 at the end of the cutting section 222 away from the blade shaft 3 provides a certain buffering force for the breaker anti-entanglement blade 21 to enter the soil. The guide section 25 between the buffer section 24 and the support section 221 guides the direction of the breaker anti-entanglement blade 21's entry into the soil, facilitating its rapid entry.

[0051] The shredder assembly 1 includes several shredder blades 11, each shredder blade 11 having a shredding section 111. The cutting section 222 of the anti-tangling shredder mechanism 2 faces the same direction as the shredding section 111 of the shredder blade 11. By ensuring that the cutting section 222 of the anti-tangling shredder 21 faces the same direction as the shredder blade 11, the anti-tangling shredder 21 and the shredder blade 11 can enter the soil or cut weeds in the same direction. During the rotary tillage of the soil by the shredder blades 11, the anti-tangling shredder 21 can shred and cut the soil or weeds in the space between the shredder blades 11, preventing weeds from tangling on the blade shaft 3, which is beneficial for rotary tillage of the gaps between the shredder assembly 1.

[0052] The shredder 11 is provided with grass shreds 112; the height of the anti-tangling shredder 21 does not exceed the edge of the grass shreds 112 away from the blade shaft 3. By ensuring that the height of the anti-tangling shredder 21 does not exceed the edge of the grass shreds 112 away from the blade shaft 3, the grass shreds 112 of the shredder 11 can first shred grass or break soil, and then the anti-tangling shredder 21 can shred grass or break soil, thus improving the shredding and anti-tangling effect of the anti-tangling shredder 21.
