Description

Technical Field

[0001] This invention relates to the field of tillage machinery technology, specifically to an integrated fertilizing, tilling, and rotary tillage machine. Background Technology

[0002] In modern agricultural planting systems, the foundation for high and stable crop yields lies in building a deep topsoil layer and a fertile soil environment to promote root development. Before sowing, base fertilizer needs to be applied, followed by deep plowing to increase the thickness of the topsoil layer. Especially under conditions of straw return to the field, plowing can deeply bury the straw, preventing it from accumulating on the soil surface. Finally, rotary tillage breaks up the soil. Deep plowing buries the surface straw deep into the soil, which not only prevents straw from affecting soil temperature rise and sowing quality but also promotes the decomposition of straw into organic matter. Combined with deep application of base fertilizer, it effectively guides crop roots downwards, enhancing drought resistance and lodging resistance. Finally, rotary tillage creates a fine and level seedbed environment for seed germination.

[0003] However, most existing traditional farming methods employ single-task machinery to perform the above procedures in stages. Farmers need to first use a fertilizer spreader to apply base fertilizer, then use a high-horsepower tractor to pull a moldboard plow for deep plowing, and finally use a rotary tiller for shallow tillage. This "segmented" operation process is cumbersome, resulting in multiple trips of machinery into the field. This not only greatly increases fuel consumption and labor costs and reduces operational efficiency, but also easily leads to soil compaction and damages soil structure due to repeated compaction. In addition, because the time span of each stage is large, it is difficult to ensure the synchronization of deep application of base fertilizer and deep burial of straw, often resulting in problems such as low fertilizer utilization and substandard quality of straw return to the field. Summary of the Invention

The plurality of fertilizer boxes are spaced apart at the bottom of the fertilizer storage box and communicate with the cavity. The plurality of fertilizer boxes are connected in series with an adjusting shaft rotatably mounted on the first frame. Two guide plates are obliquely mounted on the first frame. One side of each guide plate extends below the plurality of fertilizer boxes, and the other side of each guide plate extends downward to the front end of the two flip-cutting parts.

[0010] In some embodiments, the soil-breaking mechanism includes a second frame, a coupling member, a second linkage member, and a soil-turning member; the second frame is connected to the first frame via the coupling member, the soil-turning member is rotatably mounted on the second frame, the second linkage member is mounted on the second frame and is drivenly connected to the first linkage member, and the second linkage member is also drivenly connected to the soil-turning member; the first linkage member drives the soil-turning member to rotate through the second linkage member, so as to realize that the soil-turning member breaks up the tilled soil.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0018] To address the technical problems of cumbersome traditional tillage procedures and low efficiency due to multiple field visits in existing technologies, this invention provides an integrated fertilization, tillage, and rotary tillage machine. By completing the processes of applying base fertilizer, tilling the soil, burying straw deeply, and rotary tillage to break up the soil in one go, it significantly reduces the number of times the machine needs to enter the field. This not only saves fuel and time but also avoids soil compaction caused by multiple compactions, improving work efficiency and fertilizer utilization, and promoting crop root development and yield increase.

[0019] Please see Figures 1-8 , Figures 1-8 According to one embodiment of the present invention, a rotary tiller integrating fertilization and tillage includes a rotary tillage mechanism 1 and a soil breaking mechanism 2. The rotary tillage mechanism 1 includes a first frame 11, a first linkage 12, two turning and cutting parts 13, and a fertilizer applicator 14. The two turning and cutting parts 13 are rotatably mounted on the first frame 11 and are arranged at an angle. The distance between the front ends of the two turning and cutting parts 13 is smaller than the distance between their rear ends. The first linkage 12 is mounted on the first frame 11 and is connected to the two turning and cutting parts 13 by transmission. The first linkage 12 is configured to be driven to rotate by an external drive, driving the two turning and cutting parts 13 to rotate synchronously to till the ground. The fertilizer applicator 14 is mounted on the first frame 11 and is configured to spread fertilizer on the area to be tilled. The soil breaking mechanism 2 is mounted on the rear side of the first frame 11 and is connected to the first linkage 12 by transmission. The soil breaking mechanism 2 is used to break up the soil after it has been tilled by the two turning and cutting parts 13.

[0020] In actual use, the tillage fertilizer is connected to the tractor and is driven by the drive source inside the tractor to the first linkage 12. When the tractor pulls the tillage fertilizer, the fertilizing component 14 spreads fertilizer to the area to be tilled. The two turning and cutting components 13 rotate synchronously, which can easily cut the straw and stubble left on the surface of the previous season's crop and bury them deep into the tillage layer (usually the burial depth is about 25-30cm). The lateral component forces generated by the two turning and cutting components 13 under the action of soil resistance can cancel each other out, realizing the self-balance of the lateral force of the machine body. The high-speed stirring of the soil crushing mechanism 2 at the rear can deeply and evenly mix the turned soil, the straw residue on the surface and the fertilizer.

[0021] Specifically, the two cutting components 13 are arranged at an angle, and the lateral forces generated by the two cutting components 13 under the action of soil resistance can cancel each other out, realizing the self-balance of the lateral forces on the machine body. This effectively overcomes the side slippage and deviation phenomenon that is easy to occur when operating a traditional disc plow, greatly reduces traction resistance, and improves the stability of the machine body in straight-line travel. When the two cutting components rotate, they can easily cut the straw and stubble left on the surface of the previous season's crop. The soil crushing mechanism at the rear can deeply and evenly mix the turned soil, straw residues on the surface, and fertilizer through high-speed stirring. This allows the straw to decompose better and be converted into organic matter, and also allows the fertilizer to be evenly distributed in the tillage layer, avoiding burning of seedlings.

[0022] It should be noted that, in one embodiment, the turning and cutting component 13 includes a rotating shaft 131 and a plurality of disc plows 132; the rotating shaft 131 is rotatably mounted on the first frame 11 and is connected to the first linkage component 12 in a transmission manner, wherein the central axes of the two rotating shafts 131 are arranged in a figure-eight shape, and the plurality of disc plows 132 are installed at intervals on the rotating shaft 131, and the concave surface of each disc plow 132 faces the longitudinal centerline of the first frame 11.

[0023] Specifically, when the rotating shaft 131 rotates, it drives multiple disc plows 132 to rotate synchronously. The multiple disc plows 132 can remove the straw and stubble left on the surface by the previous season's crops and bury them deep into the cultivated layer. The lateral component force generated by the multiple disc plows 132 on the two rotating shafts 131 when rotating is canceled out in the longitudinal centerline area of ​​the first frame 11.

[0024] Furthermore, based on the above scheme, two external discs 15 are rotatably mounted on the first frame 11 and located at the front end of the two cutting pieces 13. The two external discs 15 are arranged in a figure-eight shape, and the concave surfaces of the two external discs 15 face the opposite sides of the first frame 11 respectively.

[0025] Understandably, the concave surfaces of the multiple disc plows 132 of the two turning pieces 13 all face the longitudinal centerline of the first frame 11. When the disc plows 132 rotate, they will gather the soil towards the center, resulting in a hard ridge of soil that has not been turned over at the very front of the tillage and fertilization machine. By using two external discs 15 that are rotatably mounted on the first frame 11, this hard ridge in the middle can be cut in advance and turned outward, thus perfectly filling the gap left by the rear disc and ensuring that there are no dead corners within the entire working width.

[0026] Furthermore, based on the above scheme, multiple scraper blades 16 are installed at intervals on the first frame 11, and each scraper blade 16 slides against the concave surface of each disc plow 132. It is understood that when the disc plow 132 is rolling and cutting the soil, the soil is very easy to adhere to the concave surface. By generating relative movement with the disc plow 132, the scraper blades 16 can scrape off the clay, weeds and other materials adhering to the concave surface in time, effectively solving the problem of soil adhesion and preventing the disc plow from becoming blocked. In addition, the scraper 16 can not only scrape the soil, but also enhance the breaking effect of the soil clods, assisting the disc plow 132 to better turn over the cut soil clods, making the cultivated land more level.

[0027] Based on the above scheme, in one embodiment, the fertilizer applicator 14 includes a fertilizer storage box 141 and a plurality of fertilizer boxes 142. The fertilizer storage box 141 is installed on the top of the first frame 11 and has a cavity for containing fertilizer. The plurality of fertilizer boxes 142 are spaced apart at the bottom of the fertilizer storage box 141 and communicate with the cavity. The plurality of fertilizer boxes 142 are connected in series with an adjusting shaft 111 rotatably mounted on the first frame 11. Two guide plates 112 are obliquely installed on the first frame 11. One side of each guide plate 112 extends to the bottom of the plurality of fertilizer boxes 142, and the other side of each guide plate 112 extends downward to the front end of each of the two double-flipping cutters 13.

[0028] It should be noted that the fertilizer box 142 is not limited to a specific structure. The fertilizer box 142 is a commonly used fertilizer box in the prior art; specifically, such as the universal fertilizer box with wide and narrow widths described in the prior art patent document CN208987301U; during use, the amount of fertilizer discharged by the fertilizer box 142 can be adjusted by rotating the adjusting shaft 111.

[0029] Under the action of the two guide plates 112, the discharged fertilizer can be guided to fall in front of the two turning pieces 13. In addition, there is at least one fertilizer box 142 corresponding to the two external discs 15, and the fertilizer discharged from the fertilizer box 142 can fall into the area tilled by the two external discs 15.

[0030] In one embodiment, the soil-breaking mechanism 2 includes a second frame 21, a coupling member 22, a second linkage member 23, and a soil-turning member 24. The second frame 21 is connected to the first frame 11 via the coupling member 22. The soil-turning member 24 is rotatably mounted on the second frame 21. The second linkage member 23 is mounted on the second frame 21 and is drivenly connected to the first linkage member 12. The second linkage member 23 is also drivenly connected to the soil-turning member 24. The first linkage member 12 drives the soil-turning member 24 to rotate through the second linkage member 23, so as to realize that the soil-turning member 24 breaks up the soil after tillage.

[0031] It should be noted that the coupling member 22 does not have a specific structure. In one embodiment, the coupling member 22 includes at least two connecting rods 221 and two hydraulic cylinders 222. The opposite ends of the two connecting rods 221 are respectively hinged to the first frame 11 and the second frame 21. The fixed ends of the two hydraulic cylinders 222 are hinged to the first frame 11, and the output ends of the two hydraulic cylinders 222 are hinged to the second frame 21. The two hydraulic cylinders 222 are respectively located above the two connecting rods 221.

[0032] In addition, based on the above scheme, the coupling component 22 also includes a reinforcing rod 223. The two ends of the reinforcing rod are respectively hinged to the first frame 11 and the second frame 21, and the reinforcing rod is located between the two connecting rods 221. It can be understood that when the tractor passes over uneven ground, the hydraulic cylinder can adjust the position of the second frame 21 in real time according to the ground undulation. When encountering a high place, the hydraulic cylinder retracts and the second frame 21 rises relatively; when encountering a low place, the hydraulic cylinder extends and the second frame 21 falls relatively, thereby achieving "ground-hugging contouring".

[0033] In one embodiment, the soil turning component 24 includes a mounting shaft 241 and a plurality of soil-breaking blades 242; The mounting shaft 241 is rotatably mounted on the second frame 21 and is connected to the second linkage 23 for transmission. Multiple soil-crushing blades 242 are spaced apart along the circumference of the mounting shaft 241. It can be understood that when the mounting shaft 241 drives the multiple soil-crushing blades 242 to rotate synchronously, the multiple soil-crushing blades 242 can break through this hard bottom layer, increase the porosity of the soil, improve the aeration and permeability of the soil, and at the same time, thoroughly chop up the residual weed roots and crop stubble in the soil, effectively reducing weed regeneration.

[0034] Furthermore, based on the above scheme, the material blocking component 25 is connected to the second frame 21, and the material blocking component 25 covers one side of the soil turning component 24; wherein, the material blocking component 25 includes a baffle 251 and at least one buffer part 252; one side of the baffle 251 is hinged to the second frame 21, and at least one buffer part 252 is connected between the second frame 21 and the baffle 251.

[0035] It should be noted that the buffer part 252 is not limited to a specific structure. Specifically, the buffer part 252 includes a first mounting base 2521, a second mounting base 2522, a first spring 2523, a second spring 2524, and a guide rod 2525. The first mounting base 2521 is hinged to the second frame 21, the second mounting base 2522 is fixed on the baffle 251, one end of the guide rod 2525 is hinged to the second mounting base 2522, and the guide rod 2525 passes through the sleeve 2520 rotatably mounted on the first mounting base 2521. A first limiting ring block and a second limiting ring block are respectively installed at opposite ends of the guide rod 2525. The first spring 2523 and the second spring 2524 are both sleeved on the guide rod 2525, and the first spring 2523 abuts between the first limiting ring block and the sleeve 2520, and the second spring 2524 abuts between the second limiting ring block and the sleeve 2520.

[0036] Understandably, when the soil turning component 24 rotates under the action of the baffle 251, the soil can be repeatedly broken up between the baffle 251 and the soil turning component 24, resulting in very fine soil.

[0037] It should be noted that, in one embodiment, the first linkage 12 includes a first base 121, a first bevel gear 122, a second bevel gear 123, a first shaft 124, two first universal joint assemblies 125, and two first transmission components 126; the first base 121 is mounted on the first frame 11, the first bevel gear 122 and the first shaft 124 are rotatably mounted on the first base 121, the second bevel gear 123 is mounted on the first shaft 124 and meshes with the first bevel gear 122, the two first transmission components 126 are respectively mounted on opposite sides of the first frame 11 and are respectively connected to the two cutting parts 13, one end of the two first universal joint assemblies 125 is respectively connected to the opposite ends of the first shaft 124, and the other end of the two first universal joint assemblies 125 is respectively connected to the two first transmission components 126.

[0038] The first transmission component 126 includes a first driving gear 1261, a first driven gear 1262, and at least one first transmission gear 1263. The first driving gear 1261 is rotatably mounted on the first frame 11, the first driven gear 1262 is mounted on the end of the rotating shaft 131, and at least one first transmission gear 1263 is rotatably mounted on the first frame 11 and located between the first driving gear 1261 and the first driven gear 1262. The first transmission gear 1263 meshes with the first driving gear 1261 and the first driven gear 1262. The rotating shaft of the first driving gear 1261 is connected to the other end of the first universal joint assembly 125.

[0039] In addition, the first linkage 12 also includes a third bevel gear 127 and a second universal joint assembly 128. The third bevel gear 127 is mounted on the first base 121 and meshes with the second bevel gear 123. One end of the second universal joint assembly 128 is connected to the shaft of the third bevel gear 127 for transmission. The second linkage 23 includes a second base 231, a second shaft 232, a fourth bevel gear 233, a fifth bevel gear 234, and two second transmission components 235. The second base 231 is mounted on the second frame. On the second frame 21, the fourth bevel gear 233 and the second shaft 232 are rotatably mounted on the second base 231. The fifth bevel gear 234 is mounted on the second shaft 232 and meshes with the fourth bevel gear 233. The second transmission component 235 is mounted on opposite sides of the second frame 21. The second transmission component 235 is configured to provide a transmission connection between one end of the second shaft 232 and one end of the mounting shaft 241. The other end of the second universal joint assembly 128 is transmission connected to the rotating shaft of the fourth bevel gear 233.

[0040] Specifically, the second transmission component 235 includes a second driving gear 2351, a second driven gear 2352, and at least one second transmission gear 2353. The second driving gear 2351 is mounted on one end of the second shaft 232, the second driven gear 2352 is fixed on one end of the mounting shaft 241, and at least one second transmission gear 2353 is rotatably mounted on the second frame 21 and located between the second driving gear 2351 and the second driven gear 2352, and the second transmission gear 2353 meshes with the second driving gear 2351 and the second driven gear 2352.

[0041] It should be noted that two first covers are installed on the first frame 11, and two first transmission components 126 are respectively housed in the two first covers. Two second covers are installed on the second frame 21, and two second transmission components 235 are respectively housed in the two second covers.
