Description

Technical Field

[0001] The invention relates to the technical field of deep tillage and soil topdressing, and in particular to deep tillage and soil topdressing equipment for agricultural tillage. Background Art

[0002] A subsoiler is a tillage machine used in conjunction with a high-horsepower tractor. It is mainly used for mechanized tillage between rows or in all directions for deep soil tillage. It has the functions of breaking the plow bottom layer, restoring the soil tillage layer structure, improving the soil's ability to store water and retain moisture, eliminating some weeds, reducing pests and diseases, leveling the surface, and improving the standard of agricultural mechanization operations. Using a subsoiler is conducive to improving the soil tillage layer structure, breaking the plow bottom layer, improving the soil's ability to store water and retain moisture, and promoting food growth. Subsoil fertilization is currently mainly used for no-till sowing and fertilization of corn, and can also be used for sowing and fertilization of row crops such as cotton and soybeans. Subsoil fertilization achieves three uses in one ditch (the subsoil ditch is also a fertilizer ditch and a seed bed ditch), and multiple effects are superimposed. Fertilizer is applied to the root-dense area for easy absorption. No-till sowing has the characteristics of deep tillage effect.

[0039] The second embodiment is based on the first embodiment. Figure 6 to Figure 7 As shown, the plowshare 33 includes a plowshare frame 331, which is slidably mounted in the inner cavity of the lifting sleeve 32, and an adjustment hole 335 is provided on the surface of the plowshare frame 331, and a plow cutter is fixedly mounted at the bottom of the plowshare frame 331;

[0040] The plow consists of three parts: a main plow 333, a top plow 332 and an auxiliary plow 334. The auxiliary plow 334 is installed at the bottom of the main plow 333, and the top plow 332 is installed on the top of the main plow 333. The top of the top plow 332 is fixedly connected to the bottom end of the plow head frame 331.

[0041] The buffer member 34 includes a buffer bracket 341 and a buffer fixing block 342, one end of the buffer bracket 341 is fixedly installed in the middle of the cross bar, a slide groove 345 is opened on the surface of the buffer bracket 341, the buffer fixing block 342 is fixedly installed on the end of the buffer bracket 341 away from the plowshare bracket 31, a buffer spring 343 is fixedly installed on the surface of the buffer fixing block 342, the end of the buffer spring 343 away from the buffer fixing block 342 is fixedly connected to the second slider 344, the second slider 344 is slidably installed in the inside of the slide groove 345, the end of the rotating rod 35 away from the lifting sleeve 32 is slidably installed in the inside of the slide groove 345 through the sliding shaft, and the end of the rotating rod 35 away from the lifting sleeve 32 is pressed and adapted with the second slider 344, the setting of the buffer member 34 enables the plowshare to buffer when encountering hard stones and other debris to prevent it from being stuck by stones.

[0042] The third embodiment is based on the first and second embodiments. Figure 8 As shown, the topdressing device 4 includes a motor 41 and a barrel 43, the motor 41 is fixedly installed at the bottom of the fertilizer rack 22, and the motor is arranged just above the fertilizer rake 26, a pulling disc 42 is rotatably installed inside the barrel 43, the output end of the motor 41 passes through the barrel 43 and extends into the inside, the output end of the motor 41 is fixedly connected to the axis of the pulling disc 42, a feeding pipe 44 is fixedly installed at the bottom of the barrel 43, a discharge port 45 is fixedly installed at the bottom of the feeding pipe 44, a pulling hole 46 is opened on the surface of the pulling disc 42, through the cooperation of the pulling disc 42 and the barrel 43, the solid granular fertilizer can be evenly dropped into the fertilizer groove through the pulling hole 46.

[0043] When in use, the staff first assembles the frame, and connects the traction frame 23 of the deep loosening and topdressing device to a high-horsepower tractor through a traction pin. The two traction frames 23 are symmetrically connected to the tractor, so that the tractor is evenly stressed during traction and the wear of the traction pin is reduced. The device is pulled forward by the tractor. When moving forward, the three guide wheels 12 guide the forward direction of the device to prevent the forward direction from being offset, and the surface of the guide wheel 12 is grooved to prevent the guide wheel 12 from being pressed by stones and other debris and causing bumps. The deep loosening device 2 and the plowshare assembly deeply loosen and level the soil. A hole is opened on the surface of the lifting sleeve 32, which can be matched with the adjustment hole 335. The length of the plowshare 33 can be adjusted by matching different holes, so that the soil at different depths can be loosened. The main plowshare 3 33 is inclined, so it can penetrate the soil more easily. After the main plowshare 333 destroys the surface of the soil, it penetrates deep into the soil and crushes the agglomerated soil by cooperating with the auxiliary plowshare 334 and the top plowshare 332. The auxiliary plowshare 334 is also inclined, and has the effect of turning the deep soil upwards during the forward movement. The two sides of the top plowshare 332 are also designed in the same way. In the forward movement, the soil is not only destroyed, but also the bottom soil is turned to the surface. When the plowshare 33 encounters a harder object that cannot be destroyed, such as a stone, during the forward movement, the buffer member is provided, and the collision causes the rotating rod 35 to compress the buffer spring 343, and the rotating rod 35 slides in the slide groove 345. At the same time, the rotating rod 35 drives the plowshare 33 to retract, and the plowshare 33 is lifted up to avoid the stone, so as to prevent the plowshare 33 from being stuck by the stone.

[0044] The auxiliary wheel 24 is arranged in an inward-facing position. When the deep loosening and fertilizing device is pulled forward, the auxiliary wheel body 241 supports the device to prevent it from tipping over. The auxiliary wheel body 241 rotates counterclockwise. When the auxiliary wheel body 241 rotates, the shifting block 243 can be inserted into the soil to further loosen the loosened soil near the furrow. On the other hand, the loosened soil and the internal stones in the furrow can be removed to expand the furrow and evenly spread the soil beside it, which is convenient for the subsequent application of fertilizer.

[0045] Solid particles of fertilizer are prevented from being inside the barrel 43. The output end of the motor 41 drives the pulling plate 42 to rotate. While the pulling plate 42 is rotating, the solid particles of fertilizer are transported out through the pulling hole 46 through the cooperation between the pulling plate 42 and the inside of the barrel 43. The pulling holes 46 are evenly arranged on the surface of the pulling plate 42, so that the solid fertilizer can be discharged evenly. The solid fertilizer is discharged through the feeding pipe 44 and the discharge port 45, and the solid fertilizer can fall evenly in the excavated groove. Then the fertilizer rake 26 flattens and backfills the soil, and by setting the rake claw spring 264, the support rod 261 is buffered during the forward movement of the rake claw 262 to prevent the rake claw 262 from being stuck by stones, etc. After the fertilizer rake 26 preliminarily flattens and backfills the soil beside the furrow, the compacting wheel further compacts the soil after deep loosening and topdressing to make the loosened land smooth.

[0046] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
