[0002] In recent years, the area of corn planted by adopting the protective tillage technology is gradually increased in China, and the straw returning strip tillage technology is also continuously accepted by the majority of farmers, but the single straw returning technology and strip tillage technology still have defects, the machine needs to enter the ground twice, the corn straw returning speed is not satisfactory, the strip tillage machine has a large power consumption, and there is no fertilizer application device, so that the fertilizer application operation cannot be completed, the utility model adopts the front straw smashing, the straw is broken into filaments, which is beneficial to the straw rotting, even if the straw does not rot, the straw is punched into the soil, and the sowing is not affected, then the subsoiling and the soil shallow layer are broken by the disc harrow, so that the strip tillage operation is labor-saving and more smooth, the deep base fertilizer and the whole tillage layer mixed fertilizer are applied, the corn can obtain the fertilizer supply on the whole tillage layer, the corn is not lack of fertilizer, the straw is retained, the soil fertility is cultivated, the seedbed is flat, the agricultural requirement of the upper flat and the lower real is met, and the emergence rate is guaranteed. CONTENT OF THE UTILITY MODEL
[0003] The utility model aims at providing a strip tillage machine to solve the problems in the background technology.
[0004] In order to solve the above technical problems, the utility model provides the following technical scheme: a strip tillage machine, which comprises a straw pulverizer frame, a main gear box and a transmission shaft, a lower suspension frame, an upper suspension frame, a side box transmission shaft, a strip tillage depth adjustment hydraulic cylinder, a strip tillage depth sensor, a U-shaped clamp, a press roller support, a press roller drive hydraulic motor, a press roller, a strip tillage machine frame, a strip tillage machine drive hydraulic motor, a strip tillage machine cutter roll, a disc harrow frame, a front disc harrow, a side box bearing seat, a side box, a straw pulverizer flail cutter roll, a straw separating baffle, a straw pulverizer flail cutter roll height sensor, a straw pulverizer flail cutter roll height adjustment hydraulic cylinder, a strip tillage machine frame adjustment connecting rod, a disc harrow seat, a rear disc harrow, a subsoiler seat, a subsoiler, a fertilizer box, a disc harrow fertilizer pipe, a subsoiler fertilizer pipe, a curved flail, a straight flail, a strip tillage seven-character cutter, a straw pulverizer flail cutter roll bearing seat plate, a straw pulverizer upper cover plate, a straw pulverizer fixed cutter and a height adjustment hydraulic cylinder seat, characterized in that the straw pulverizer flail cutter roll is counterclockwise high-speed rotation, which sprays the straw into filaments to the front straw separating baffle, the straw in the filaments is separated to both sides of the machine by the inclined straw separating baffle, and a clean strip tillage belt is left.
[0005] Furthermore, the height of the straw crusher's blade roller is controlled by a straw crusher blade roller height sensor. The straw crusher blade roller height sensor detects the height of the implement off the ground and sends a height adjustment signal to the straw crusher blade roller height adjustment hydraulic cylinder at any time. The straw crusher blade roller height adjustment hydraulic cylinder actuates to adjust the height of the straw crusher blade roller so that it just maintains the set value of only chopping the straw on the ground without hitting the soil.
[0006] Furthermore, curved and straight blades are installed on the blade roller of the straw crusher, and fixed blades are welded to the upper cover plate of the straw crusher. The curved and straight blades and the fixed blades of the straw crusher form a straw kneading and crushing system. The maximum kneading and crushing working width is 800 mm. The kneading and crushing working width can be changed by symmetrically removing the curved and straight blades on both sides. The minimum kneading and crushing working width is set at 300 mm. That is to say, the kneading and crushing working width can be manually set between 300 mm and 800 mm.
[0007] Furthermore, a deep loosening shovel seat is installed behind the frame of the straw crusher. A deep loosening shovel is installed on the deep loosening shovel seat. The deep loosening operation of the deep loosening shovel breaks the plow pan, allowing water to flow through the soil and reducing the operating resistance of the following implements.

The two front disc harrows in row I are placed in an inward V-shape, and their distance L1 can be adjusted between 300 mm and 800 mm. The two rear disc harrows in row II are placed in an outward V-shape, and their distance L2 can also be adjusted between 300 mm and 800 mm. However, the disc harrows in rows I and II need to be staggered. For example, if the distance L1 of row I is 800 mm, then the distance L2 of row II is 300 mm. This leaves space to avoid soil accumulation. Since both rows of disc harrows are placed in an inward V-shape, they move more soil, which reduces resistance for subsequent strip tillage operations.
[0009] Furthermore, a fertilizer box is installed on the disc harrow frame, and a deep tillage shovel fertilizer pipe is installed at the bottom of the shovel handle. The fertilizer box and the deep tillage shovel fertilizer pipe form a base fertilizer application system, which applies base fertilizer at the same time during the deep tillage process.
[0010] Furthermore, a strip tiller frame is set behind the disc harrow frame, and a strip tiller cutter roller is installed under the strip tiller frame. The strip tiller cutter roller is driven by a strip tiller drive hydraulic motor, which reduces the complexity of mechanical transmission and increases the reliability of the implement.
[0011] Further, the strip tillage frame is provided with a strip tillage depth adjusting hydraulic cylinder and a strip tillage depth sensor, the strip tillage depth is controlled by the strip tillage depth sensor, the strip tillage depth sensor detects the working depth of the machine at any time, and sends a depth adjusting signal to the strip tillage depth adjusting hydraulic cylinder, the strip tillage depth adjusting hydraulic cylinder changes the up-down position of the strip tillage frame, so that the strip tillage working depth is kept at a set depth, and the strip tillage working depth is kept uniform.
[0012] Further, the strip tillage machine cutter roller is provided with strip tillage seven-character cutters, the maximum strip tillage working width of the strip tillage seven-character cutters is 800 mm, the strip tillage working width can be changed by symmetrically removing the strip tillage seven-character cutters on both sides, and the minimum strip tillage working width is set to 300 mm, that is, the strip tillage working width can be adjusted between 300 mm and 800 mm.
[0013] Further, the front disc harrow and the rear disc harrow are provided with disc harrow fertilizer pipes, the disc harrow fertilizer pipe and the fertilizer tank form a full tillage layer fertilization system, in the working process, the disc harrow fertilizer pipe is used for scattering chemical fertilizer in the trench cut by the disc harrow, and the chemical fertilizer scattered by the disc harrow fertilizer pipe is fully mixed with soil in the subsequent strip tillage operation, so that full tillage layer mixed fertilization is formed, and the full growth period of corn is supported.
[0014] Further, a roller support is arranged behind the strip tillage frame, a roller is arranged on the roller support, and the roller is driven by a roller driving hydraulic motor to roll and smooth the land after strip tillage, so that a smooth seedbed is formed and the next step of sowing is prepared.
