Description

Technical Field

[0001] This utility model relates to the field of rotary tillage machine technology, and in particular to a deep tillage, rotary tillage and compaction combined tillage machine. Background Technology

[0002] Land preparation machines are core equipment used for soil cultivation in agricultural production. They are applied in the soil preparation stage before sowing. Their core function is to break up, loosen and improve farmland soil through mechanical action, creating a suitable soil environment for subsequent crop sowing, emergence and growth. In practical applications, land preparation machines can effectively break up the compacted layer formed by long-term cultivation of farmland, increase soil porosity, and improve soil aeration and water and fertilizer retention capacity. They are one of the key links in modern agricultural production to ensure high and stable crop yields. The deep tillage, rotary tillage, and compaction combined tillage machine is an integrated farming machine developed from traditional single-function tillage equipment. It integrates the three core tillage processes of deep tillage, rotary tillage, and compaction into a single machine body. It can complete the soil tillage process that originally required multiple machines and multiple trips in one field operation. The deep tillage function is achieved by the deep tillage shovel at the front of the machine, which can penetrate deep into the soil to break up the plow pan, open up the channels for the conduction of water and nutrients between the upper and lower soil layers, reduce the number of times the agricultural machine enters the field, reduce operating costs and soil compaction risks, and is an important piece of equipment in the current efficient agricultural tillage mode. Existing deep tillage, rotary tillage, and compaction combined land preparation machines avoid the problems of repeated soil compaction, low work efficiency, and high energy consumption caused by traditional multi-equipment, multi-stage operations through an integrated process of deep tillage, rotary tillage, and compaction. However, in actual operation, the distance between the deep tillage shovel and the rotary tillage roller of the existing equipment is fixed and lacks an adaptive adjustment mechanism. When there are significant differences in soil hardness in farmland, the deep tillage shovel cannot adjust its penetration depth in real time according to soil hardness, resulting in insufficient deep tillage depth in some areas, failing to effectively break up the plow pan, affecting soil fertility, and causing large clods of soil to appear in some areas, requiring secondary crushing, which increases operating costs.

Telescopic rods 205 are fixedly connected to the bottom of the two horizontal plates 204, allowing adjustment of the height of the sliding plate 206 to change the rotary tillage depth. Sliding plates 206 are fixedly connected to the bottom ends of the two telescopic rods 205, enabling... The rotating rod 207 and motor 209 are supported. The rotating rod 207 is rotatably connected to the adjacent side of the two sliding plates 206, which can drive the rotary cutter 208 to rotate. Multiple rotary cutters 208 are fixedly connected to the outer wall of the rotating rod 207, which can cut and break the soil. The motor 209 is fixedly connected to the right side of the right sliding plate 206, which can provide power for the rotation of the rotary cutter 208. The output end of the motor 209 passes through the sliding plate 206 and is fixedly connected to the right end of the rotating rod 207, realizing the transmission of power to the rotating rod 207. The moving component 210 is provided on the adjacent side of the two sliding plates 206, which can enhance the moving stability of the sliding plate 206. The bottom of the two telescopic rods 205 is provided with a guide component 211, which can guide the sliding plate 206 to move vertically. The moving component 210 includes multiple moving blocks 2101, which can cooperate with the moving slots 2102 to limit the offset of the sliding plate 206. One side of each of the multiple moving blocks 2101 is fixedly connected to the front and rear ends of the adjacent side of the sliding plate 206 to realize the connection between the moving blocks 2101 and the sliding plate 206. The front and rear ends of the two extension plates 202, which are far apart from each other, are provided with moving slots 2102 to provide a moving path for the moving blocks 2101.

Specifically, the mounting frame 1, as a core connecting component, can be fixed to power equipment such as tractors to enable the movement of the entire machine. Simultaneously, multiple deep-loosening shovels 4 fixed at its bottom can cut into the soil as the machine moves forward, breaking up the plow pan formed by long-term tillage, increasing soil porosity, and improving rainwater infiltration capacity, thus loosening the subsoil. In the rotary tillage mechanism 2 fixed to the rear of the mounting frame 1, a U-shaped frame 201 provides the mounting base for the rotary tillage component. Extended plates 202 fixed to the left and right sides of its bottom have sliding grooves 203, which cooperate with moving blocks 2101 fixed at the front and rear ends of the adjacent side of the sliding plate 206 to assist in the stable movement of the sliding plate 206.

The height of the sliding plate 206 can be adjusted by extending and retracting the telescopic rod 205, thereby changing the distance between the rotating rod 207 and the ground to adjust the rotary tillage depth. The guide rods 2111 fixed on the front and rear sides of the bottom of the horizontal plate 204 are inserted into the guide holes 2112 at the top of the sliding plate 206 to prevent the sliding plate 206 from shifting when moving and to ensure uniform rotary tillage depth. Multiple rotary blades 208 are fixed on the outer wall of the rotating rod 207 that is rotatably connected to the adjacent sides of the sliding plate 206. The output end of the motor 209 fixed on the right side of the sliding plate 206 passes through the sliding plate 206 and is connected to the rotating rod 207. Starting the motor 209 can drive the rotating rod 207 to rotate at high speed, so that the rotary blades 208 cut and crush the surface soil after being treated by the deep loosening shovel 4, thereby achieving the effect of refining the surface soil.

[0017] Reference Figure 1 and Figure 5 The compaction mechanism 3 includes a connecting frame 301, which serves as the basic frame for connecting various components. The front side of the connecting frame 301 is fixedly connected to the rear side of the U-shaped frame 201, achieving a stable connection between the compaction mechanism 3 and the rotary tillage mechanism 2. Mounting plates 302 are fixedly connected to both the left and right sides of the connecting frame 301, providing installation support for subsequent adjustment components. Grooves 303 are provided on adjacent sides of the two mounting plates 302, providing space for the sliding block 304 to move up and down. Sliding blocks 304 are slidably connected inside the two grooves 303, which can drive the compaction roller 305 to adjust its height to adapt to different soils. The compaction roller 305 is rotatably connected to adjacent sides of the two sliding blocks 304, which compacts and compacts the soil by rolling. A fixing component 306 is provided on one side of the mounting plate 302, which can lock the position of the sliding block 304 to keep the height of the compaction roller 305 stable. The fixing component 306 includes a fixing plate 3061, which can be inserted into a fixing slot 3062 to limit and fix the sliding block 304. The adjacent ends of the two fixing plates 3061 are respectively slidably connected to the opposite side of the corresponding sliding block 304 to ensure that the fixing plate 3061 can move flexibly. The opposite side of the two mounting plates 302 is provided with multiple fixing slots 3062, which can cooperate with the fixing plate 3061 to achieve multi-level height adjustment and fixation. The top of the fixing plate 3061 is provided with a limiting component 307 to prevent the fixing plate 3061 from accidentally loosening and falling off. The limiting component 307 includes a limiting plate 3071 that can be inserted into a limiting groove 3072 to perform secondary limiting on the fixed insert plate 3061. The bottoms of the two limiting plates 3071 are slidably connected to the tops of the corresponding fixed insert plates 3061, ensuring that the limiting plates 3071 can slide flexibly to achieve limiting or unlocking. The tops of the two fixed insert plates 3061 are provided with limiting grooves 3072 on the opposite sides to provide engagement space for the limiting plates 3071 to ensure the limiting effect. Specifically, the connecting frame 301, as a basic connecting component, is fixed to the rear side of the U-shaped frame 201 on its front side to ensure that the compaction operation is carried out synchronously with the whole machine. Grooves 303 are formed on adjacent sides of the mounting plates 302 fixed to the left and right sides of the connecting frame 301. Sliding blocks 304, slidably connected within the grooves 303, can move up and down along the grooves 303. The compaction rollers 305, rotatably connected to the adjacent sides of the sliding blocks 304, change height as the sliding blocks 304 move, adapting to different soil compaction requirements and enabling compaction operations on soils in different states. A fixing plate 306 is fixed in the fixing component 306 on one side of the mounting plate 302. 1. The adjacent end is slidably connected to the side away from the sliding block 304, pushing the fixed insert plate 3061 into the fixed groove 3062 on the side away from the mounting plate 302, which can fix the position of the sliding block 304, thereby locking the height of the pressing roller 305 and ensuring the stability of the pressing depth. In the limiting component 307 at the top of the fixed insert plate 3061, the bottom of the limiting plate 3071 is slidably connected to the top of the fixed insert plate 3061, and the sliding limiting plate 3071 is inserted into the limiting groove 3072 at the top of the fixed insert plate 3061, which can prevent the fixed insert plate 3061 from loosening and further ensure the stability of the working position of the pressing roller 305.

[0018] Reference Figure 3 and Figure 4 Multiple movable blocks 2101 are fixedly connected to sliders 5 on their front and rear sides, which can enhance the stability of the cooperation between the movable blocks 2101 and the sliding grooves 6. Multiple movable grooves 2102 are provided with sliding grooves 6 on their front and rear sides, which can provide a sliding trajectory for the sliders 5 to prevent deviation. Multiple guide rods 2111 are slidably connected to the inside of the guide holes 2112, which can guide the sliding plate 206 to move vertically and avoid tilting. The adjacent sides of the two sliding plates 206 are respectively attached to one side of the corresponding extension plate 202, which can limit the lateral displacement of the sliding plate 206 and ensure positional stability. Specifically, the sliders 5 fixed on the front and rear sides of multiple moving blocks 2101 slide in conjunction with the sliding grooves 6 opened on the front and rear sides inside the moving groove 2102, which can enhance the stability of the moving blocks 2101 during movement and prevent them from deviating. Multiple guide rods 2111 are slidably connected to the inside of the guide holes 2112, which can accurately guide the sliding plate 206 to move up and down and prevent tilting. The adjacent side of two sliding plates 206 is in contact with the corresponding side of the extension plate 202, which further restricts the lateral displacement of the sliding plate 206. These components work together to ensure that the sliding plate 206 drives the rotating rod 207 and the rotary blade 208 to adjust the position stably, ensuring uniform rotary tillage depth and improving the rotary tillage operation effect.

[0019] Working principle: When using this equipment, the mounting frame 1 moves forward, and the multiple deep tillage shovels 4 fixed at its bottom cut into the soil first, breaking the plow pan with their sharp structure. The front side of the U-shaped frame 201 of the rotary tillage mechanism 2 is fixed to the rear side of the mounting frame 1 and moves with the whole system. The motor 209 is started, and the output end drives the rotating rod 207 to rotate at high speed, causing the multiple rotary blades 208 fixed on the outer wall of the rotating rod 207 to cut and break the surface soil treated by the deep tillage shovels 4. If it is necessary to adjust the rotary tillage depth, it can be extended or retracted by the telescopic rod 205 at the bottom of the horizontal plate 204 fixed on the left and right sides of the U-shaped frame 201. The sliding plate 206 at the bottom of the rod 205 moves up and down. At this time, the moving block 2101 fixed at the front and rear ends on the adjacent side of the sliding plate 206 slides along the moving groove 2102 on the side away from the extension plate 202 fixed on the left and right sides of the bottom of the U-shaped frame 201. At the same time, the guide rod 2111 fixed at the front and rear sides of the bottom of the horizontal plate 204 is inserted into the guide hole 2112 at the top of the sliding plate 206 to ensure that the sliding plate 206 moves vertically without deviation and the rotary tillage depth is uniform. Finally, the compaction mechanism 3 on the rear side of the rotary tillage mechanism 2 moves with the whole machine to reduce surface porosity to retain moisture and make the soil particles tightly bound. Furthermore, the compaction mechanism 3 is fixed to the rear side of the U-shaped frame 201 of the rotary tillage mechanism 2 via the front side of the connecting frame 301. As the whole machine moves, the mounting plates 302 on the left and right sides of the connecting frame 301 have grooves 303 on adjacent sides. The sliding blocks 304 inside are rotatably connected to the compaction roller 305 on adjacent sides. By adjusting the position of the sliding blocks 304 in the grooves 303, the height of the compaction roller 305 can be changed to adapt to different soil compaction requirements. After adjustment, it is fixed by the fixing component 306. The fixing plate 3061 on one side of the mounting plate 302 is pushed toward the sliding block 304 so that it is inserted into the fixing groove 3062 on the opposite side of the mounting plate 302. The limiting plate 3071 at the top of the sliding fixing plate 3061 is slid so that it is locked into the limiting groove 3072 at the top of the fixing plate 3061 to prevent the fixing plate 3061 from loosening. Finally, the compaction roller 305 stably compacts the soil.
