Description

Technical Field

[0001] The invention relates to the technical field of tillers, in particular to a multifunctional tiller for mountainous and hilly areas. Background Art

[0002] A tiller is an agricultural machine used for ploughing land. Its main functions include loosening the soil, breaking up clods, weeding, and improving soil structure to prepare for planting crops. There are many types and functions of tillers, depending on the terrain and agricultural needs. For example, rotary tillers are suitable for shallow tillage of general soil, while plow tillers can go deep into the soil and are suitable for large areas of farmland. Shovel tillers are used for shallow loosening and gardening operations. Mountain and hill tillers have strong climbing and anti-skid systems to adapt to complex terrain, while crawler tillers are suitable for soft or slippery terrain and provide higher stability. Tiller design features include high-strength blades to cope with soils of different hardness, and the power system is usually diesel or electric.

[0003] The surface of mountainous and hilly areas is often formed by the weathering of rocks. During the weathering process, a large amount of gravel and small stones are produced. These particles are mixed in the soil, making the soil structure relatively compact and hard. The power system of the tiller is usually suitable for flat land and general soil, with low torque and power. When encountering mountainous lumpy soil layers, the density of the soil increases, and the power system is difficult to provide enough power to loosen and break the hard soil.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the present invention provides a multifunctional mountain and hill tiller, which has the following beneficial effects:

[0018] 1. The multifunctional mountain and hill tiller uses a loosening mechanism. The main shaft drives the transmission shaft to rotate, and the transmission shaft drives the cam to rotate. When the cam rotates, it contacts the bottom semicircular block. Under the action of spring 1, the square free block, the connecting column, the support and the cam can move up and down reciprocatingly. The support drives the sliding long block and the bottom loosening column to move up and down reciprocatingly, so that the bottom loosening column reciprocates and knocks the bottom land, breaking and loosening the hard soil blocks, reducing the density of the soil, creating a softer soil structure for subsequent farming, and improving the tilling effect and working efficiency. It solves the problem that the power system of the tiller is difficult to effectively loosen and break the agglomerated soil layer of mountain and hills.

[0019] 2. This multifunctional mountain and hilly tiller utilizes the tilling mechanism setting. The driving mechanism is turned on to drive the main shaft to rotate. The main shaft drives the blades to rotate. The blades are arranged in an array on the surface of the main shaft. The soil can be effectively crushed and loosened. The setting of the protective cover can prevent the broken soil from splashing upwards, ensuring safe operation and keeping the working environment clean.

[0020] 3. This multifunctional mountain and hilly tiller uses a loosening mechanism. The cam part rotates while driving the side semicircular block. Under the action of spring 2, the support part and the side semicircular block move back and forth horizontally. The support part drives the sliding long block and the bottom loosening column to move back and forth horizontally. Combined with the vertical knocking mentioned above, this combination of horizontal movement and vertical knocking can provide a more comprehensive soil crushing effect. Vertical knocking helps to directly break up the lumps in the soil layer, while the horizontal reciprocating movement can ensure that the loosening column evenly crushes the soil at different angles and positions, making the soil layer looser, further improving the turning effect, adapting to the complex terrain of the lumped soil layer, and improving work efficiency.

[0021] 4. The multifunctional mountain and hill tiller is set up by a reciprocating mechanism. The cam part rotates while driving the J-block. At the same time, the J-block moves back and forth longitudinally under the action of spring three. The longitudinal reciprocating movement of the J-block drives the main gear to rotate forward and backward repeatedly. The main gear drives the connecting racks 2 and the sliding strip blocks on both sides to move back and forth relative to each other horizontally. The sliding strip blocks drive the bottom loosening column to move back and forth relative to each other horizontally. The horizontal reciprocating relative movement of the bottom loosening column destroys the soil blocks adhered to the bottom loosening column, further ensuring the comprehensive crushing and loosening of the soil during the tilling process, avoiding the soil in local areas from being unprocessed, improving the tilling effect and efficiency, and reducing the unevenness of soil crushing, so as to adapt to complex soil conditions.

[0022] 5. This multifunctional mountain and hill tiller is set up with a reciprocating mechanism. When the sliding strip drives the gear and the sliding strip to move back and forth, the gear rotates back and forth under the action of the side rack, and the side rack drives the bottom loosening column to rotate. The role of rotation is that rotation can better destroy the lumps of soil. When knocking, the role of rotation enables the bottom loosening column to contact the soil at different angles and directions, increasing the cutting and crushing effect of the soil layer, mainly because the rotation can enable the bottom loosening column to generate multi-directional force when it contacts the soil. This multi-directional movement helps the loosening column enter the soil layer more comprehensively, and can cut and crush along different paths and angles, avoiding processing the soil only by force in a single direction. Especially when facing lumpy soil layers, self-rotation can enhance the penetration and crushing force on hard soil clods, thereby loosening the soil layer more effectively, improving the air permeability and softness of the soil, and promoting the smooth progress of subsequent tillage. Especially for hard lumpy soil layers, the conical bottom design also helps to penetrate deeper into the soil through self-rotation, enhance the crushing force, make the soil looser more evenly, improve the overall soil turning effect, and effectively cope with the challenges of lumpy soil.

[0036] The loosening mechanism 3 includes a support frame 31, which is fixedly connected to the bottom of the machine body 1. A transmission shaft 32 is rotatably connected to the inner wall of the support frame 31.

Under the action of the spring 1 34, the square free block 35, the connecting column 38, the support member 39 and the cam member 310 can move up and down reciprocatingly. The support member 39 drives the sliding long block 45 and the bottom loosening column 48 to move up and down reciprocatingly, so that the bottom loosening column 48 reciprocates the bottom soil to break and loosen the hard soil. When the cam member 310 rotates, it drives the side semicircular block 312. Under the action of the spring 2 37, the support member 39 and the side semicircular block 312 move back and forth horizontally. The support member 39 drives the sliding long block 45 and the bottom loosening column 48 to move back and forth horizontally. Combined with the vertical knocking mentioned above, this combination of horizontal movement and vertical knocking can provide a more comprehensive soil crushing effect.

[0037] The reciprocating mechanism 4 includes a J-shaped block 41, the outer wall of the J-shaped block 41 is fixedly connected to one end of a spring three 43, the other end of the spring three 43 is fixedly connected to the outer wall of the support member 39, the outer wall of the J-shaped block 41 is provided with a connecting rack one 42, the inner wall of the support member 39 is rotatably connected to a main gear 44, the bottom of the support member 39 is slidably connected to a sliding strip block 45, the surface of the sliding strip block 45 is provided with a connecting rack two 46, the inner wall of the sliding strip block 45 is rotatably connected to a self gear 47, and the self gear 47 is rotatably connected to the self gear 47.

[0038] To sum up, the multifunctional mountain and hill tiller, when the driving mechanism 22 is turned on, drives the main shaft 23 to rotate, and the main shaft 23 drives the blades 24 to rotate. The blades 24 are arranged in an array on the surface of the main shaft 23, which can effectively crush and loosen the soil. The setting of the protective cover 21 can prevent the broken soil from splashing upward, thereby ensuring safe operation and keeping the working environment clean.

[0039] The main shaft 23 drives the transmission shaft 32 to rotate, and the transmission shaft 32 drives the cam member 310 to rotate. When the cam member 310 rotates, it contacts the bottom semicircular block 311. Under the action of the spring 1 34, the square free block 35, the connecting column 38, the support member 39 and the cam member 310 can move up and down reciprocatingly. The support member 39 drives the sliding long block 45 and the bottom loosening column 48 to move up and down reciprocatingly, so that the bottom loosening column 48 strikes the bottom land reciprocatingly, breaking and loosening the hard soil blocks, reducing the density of the soil, creating a softer soil structure for subsequent tillage, and improving the tillage effect and work efficiency. It solves the problem that the power system of the tiller is difficult to effectively loosen and break the soil layers of mountainous hills.

[0040] The cam member 310 rotates while driving the side semicircular block 312. Under the action of the spring 2 37, the support member 39 and the side semicircular block 312 move back and forth horizontally. The support member 39 drives the sliding strip block 45 and the bottom loosening column 48 to move back and forth horizontally. Combined with the vertical knocking mentioned above, this combination of horizontal movement and vertical knocking can provide a more comprehensive soil crushing effect. Vertical knocking helps to directly break up the lumps in the soil layer, while the horizontal reciprocating movement can ensure that the loosening column evenly crushes the soil at different angles and positions, making the soil layer looser, further improving the soil turning effect, adapting to the complex terrain of the lumped soil layer, and improving work efficiency.

[0041] The cam member 310 rotates while driving the J-block 41. At the same time, the J-block 41 moves back and forth longitudinally under the action of the spring three 43. The longitudinal reciprocating movement of the J-block 41 drives the main gear 44 to rotate forward and backward repeatedly. The main gear 44 drives the connecting racks 2 46 and the sliding strips 45 on both sides to move back and forth relative to each other. The sliding strips 45 drive the bottom loosening column 48 to move back and forth relative to each other. The bottom loosening column 48 moves back and forth relative to each other, so that the soil blocks adhered to the bottom loosening column 48 are destroyed, further ensuring the comprehensive crushing and loosening of the soil during the tilling process, avoiding the soil in local areas from being unprocessed, improving the tilling effect and efficiency, and reducing the unevenness of soil crushing to adapt to complex soil conditions.

[0042] At the same time, when the sliding strip 45 drives the self-gear 47 to move back and forth with the sliding strip 45, the self-gear 47 reciprocates under the action of the side rack 49, and the side rack 49 drives the bottom loosening column 48 to rotate. The role of rotation is that rotation can better destroy the agglomeration of soil. When knocking, the role of rotation enables the bottom loosening column 48 to contact the soil at different angles and directions, increasing the cutting and crushing effect on the soil layer, mainly because the rotation can enable the bottom loosening column to generate multi-directional forces when contacting the soil. This multi-directional movement helps the loosening column to enter the soil layer more comprehensively, and can be cut and crushed along different paths and angles, avoiding processing the soil only by a single-direction force. Especially when facing lumpy soil layers, self-rotation can enhance the penetration and crushing force on hard soil clods, thereby loosening the soil layer more effectively, improving the air permeability and softness of the soil, and promoting the smooth progress of subsequent tillage. Especially for hard lumpy soil layers, the conical bottom design also helps to penetrate deeper into the soil through self-rotation, enhance the crushing force, make the soil looser more evenly, improve the overall soil turning effect, and effectively cope with the challenges of lumpy soil.

[0043] The device can not only turn the soil, but also break up soil lumps before turning the soil, which is convenient for use in mountainous and hilly areas.
