Description

Technical Field

[0001] This invention relates to the field of agricultural machinery, and more specifically, to a root-breaking device for tilling agricultural machinery. Background Technology

[0002] With the improvement of agricultural mechanization, returning crop straw to the field has become an important measure to improve soil fertility, improve soil structure, and reduce environmental pollution. However, traditional methods of returning straw to the field, such as direct crushing and broadcasting or shallow plowing, have some technical problems. Evenly broadcasting crushed straw may result in excessively thick local straw accumulation, affecting the accuracy of subsequent sowing operations and the germination rate.

[0003] When crushing straw and roots, the fragments are often scattered haphazardly across the cultivated area, failing to achieve precise straw return to the field and ineffectively addressing the issues of soil covering and aeration after straw return. This results in exposed straw, which is easily blown away by the wind or has low decomposition efficiency. To address this, we propose a root-breaking device for agricultural machinery used in tillage. Summary of the Invention

[0004] This invention provides a root-breaking device for agricultural machinery used in tillage, which solves the technical problems in related technologies that fail to achieve precise straw return to the field, and also fail to effectively solve the problems of soil covering and aeration after straw return to the field, resulting in exposed straw, easy wind blowing or low decomposition efficiency.

[0005] This invention provides a root-breaking device for agricultural machinery tilling, comprising: a root-breaking machine, wherein a straw partitioning mechanism is provided behind the tilling area of ​​the rotary tiller blade of the root-breaking machine for conveying crushed straw and straw roots into the gaps of the tillage cage;

[0006] The straw zoning mechanism includes a zoning frame, multiple conveyor belts, a slag collection box, and a soil covering component. The slag collection box is fixed above the soil turning area of ​​the root breaker's rotary tiller blade, and its slag discharge direction corresponds to the zoning frame. Multiple conveyor belts are installed inside the zoning frame, and the movement directions of each conveyor belt converge at the gap of the tillage cage.

[0007] The soil covering assembly includes a slag discharge frame and a bulldozer plate; the slag discharge frame is fixed to the material discharge area of ​​the partitioned cross frame, and the bulldozer plate is installed below it, with the bulldozer plate inclined towards the direction of travel of the root breaker;

[0008] During operation, the rotary tiller's blades rotate at high speed to crush soil, straw, and straw roots. The crushed material is carried away and falls into the slag collection box, then conveyed by the conveyor belt to the slag discharge frame and into the gaps of the tillage cage. Simultaneously, the bulldozer blades scoop up the crushed soil to cover the straw and straw roots, forming a straw-soil composite covering layer.

[0009] Furthermore, a guide plate 1 and a guide plate 2 are fixedly installed on the inner side of the slag discharge frame. The guide plate 1 is inclined in the opposite direction to the movement of the root breaking machine, and the guide plate 2 is inclined in the same direction as the movement of the root breaking machine. The guide plate 1 and the guide plate 2 do not contact each other, and the straw and straw roots falling into the slag discharge frame are discharged from the gap between the guide plate 1 and the guide plate 2.

[0010] Furthermore, a guide arm is fixedly installed at the center of the lower wall of the slag frame, and a lifting arm is installed at the bottom of the guide arm. The lifting arm and the guide arm form a telescopic structure. A soil-pressing column is rotatably installed on the inner side of the bottom of the lifting arm. Several perforated columns are arrayed on the outer wall of the soil-pressing column, and the top of the perforated column is an inclined surface. The perforated column is a quadrangular prism.

[0011] Furthermore, a height adjustment block is provided on the rear side of the guide arm and is fixedly connected to the slag discharge frame. A vertical lifting arm is slidably provided on the inner side of the height adjustment block. The bottom of the vertical lifting arm is fixedly connected to the bulldozer plate. An adjustment bolt is provided at the top center of the height adjustment block. The adjustment bolt passes through the slag discharge frame and the vertical lifting arm from top to bottom and is rotatably connected to the vertical lifting arm. The adjustment bolt is threadedly connected to the slag discharge frame and the vertical lifting arm.

[0012] Furthermore, the bulldozer blade has a soil covering opening inside. The bottom of the bulldozer blade is inserted into the freshly broken soil, causing the broken soil to move up the bulldozer blade and finally spray out from the soil covering opening onto the straw and straw roots.

[0013] Furthermore, a soil-pressing roller is rotatably installed at the end of the partitioned crossbeam that is far from the crushing zone of the root-breaking machine. The soil-pressing roller is parallel to the partitioned crossbeam and is in contact with the ground at a height lower than that of the partitioned crossbeam.

[0014] Furthermore, each conveyor belt has drive rollers at both ends, and a transmission box is fixedly installed on the side of the partition crossbeam away from the slag receiving box. The tops of several drive rollers pass through the partition crossbeam and are located in the transmission box, and drive wheels are fixedly installed on the tops of the drive rollers.

[0015] Furthermore, a drive motor is installed above both ends of the partitioned crossbeam, and a transmission belt is installed on the pulley of the drive motor. The end of the transmission belt away from the drive motor passes through the transmission box and connects to the drive wheel of the drive roller.

[0016] Furthermore, the inside of the slag receiving box is equipped with a straw pushing roller, on which several sets of slag-removing arms are arrayed, and the slag-removing arms are semi-circular. A transmission chain is connected to the center of the straw pushing roller, and the other end of the transmission chain is connected to the rotating shaft of the rotary tiller blade of the root breaker.

[0017] Furthermore, a slag outlet is provided on the side of the slag receiving box near the partition crossbeam, and several soil shaking arms are rotatably installed on the bottom wall of the slag outlet, with the other end of the soil shaking arms resting on the conveyor belt.

[0018] The beneficial effects of this invention are as follows:

[0019] This invention achieves the directionality and precision of straw return to the field by setting a straw partitioning mechanism behind the soil turning area of ​​the rotary tiller blade and having a slag collection box collect the slag, and then accurately transporting the straw and straw roots to the gaps in the tillage cage via a conveyor belt. This avoids disorderly scattering and accumulation of straw, which is beneficial to subsequent sowing operations and crop growth.

[0020] The bulldozer blade in the soil covering component is set at an angle and can simultaneously scoop up broken soil to cover the straw and straw roots, forming a straw-soil composite covering layer, which effectively solves the problem of exposed straw, prevents the straw from being blown away by the wind or washed away by rain, and provides a good environment for straw decomposition.

[0021] By setting soil-pressing columns and perforated columns in the soil covering component, air pores can be pierced on the surface of the soil covering layer, increasing the contact area between the soil and air, accelerating the aerobic decomposition of straw, and improving the decomposition efficiency of straw returning to the field.

[0030] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0031] like Figures 1-7 As shown, a root-breaking device for tilling agricultural machinery includes: a root-breaking machine 11, and a straw partitioning mechanism 2 is provided behind the tilling area of ​​the rotary tiller blade of the root-breaking machine 11 for conveying crushed straw and straw roots into the gaps of the tillage cage.

[0032] The straw partitioning mechanism 2 includes a partitioning crossbeam 21, multiple conveyor belts 23, a slag collection box 27, and a soil covering component; the slag collection box 27 is fixed above the soil turning area of ​​the rotary tiller blade of the root breaker 11, and its slag discharge direction corresponds to the partitioning crossbeam 21; multiple conveyor belts 23 are provided inside the partitioning crossbeam 21, and the movement directions of each conveyor belt 23 converge at the gap of the tillage cage.

[0033] The soil covering assembly includes a slag discharge frame 31 and a bulldozer plate 39; the slag discharge frame 31 is fixed to the material discharge area of ​​the partitioned cross frame 21, and the bulldozer plate 39 is provided below it, with the bulldozer plate 39 inclined towards the direction of travel of the root breaking machine 11.

[0034] During operation, the rotary tiller 11 rotates at high speed to crush soil, straw and straw roots. The crushed material is carried away and falls into the slag collection box 27. It is then conveyed by the conveyor belt 23 to the slag frame 31 and falls into the gap of the tillage cage. Simultaneously, the bulldozer 39 scoops up the crushed soil to cover the straw and straw roots, forming a straw-soil composite covering layer.

[0035] Inside the slag frame 31, there are two guide plates: a first guide plate 32 and a second guide plate 34. The first guide plate 32 is inclined in the opposite direction to the movement of the root breaking machine 11, and the second guide plate 34 is inclined in the same direction as the movement of the root breaking machine 11. The first guide plate 32 and the second guide plate 34 do not contact each other. The straw and straw roots that fall into the slag frame 31 are discharged from the gap between the first guide plate 32 and the second guide plate 34.

[0036] A guide arm 37 is fixedly installed at the center of the lower wall of the slag frame 31. A lifting arm 35 is installed at the bottom of the guide arm 37. The lifting arm 35 and the guide arm 37 form a telescopic structure. A soil-pressing column 33 is rotatably installed on the inner side of the bottom of the lifting arm 35. Several perforated columns 36 are arrayed on the outer wall of the soil-pressing column 33. The top of the perforated column 36 is an inclined surface and the perforated column 36 is a quadrangular prism.

[0037] The rear side of the guide arm 37 is provided with an adjustment block 38 that is fixedly connected to the slag frame 31. The inner side of the adjustment block 38 is provided with a vertical lifting arm 302. The bottom of the vertical lifting arm 302 is fixedly connected to the bulldozer plate 39. The top center of the adjustment block 38 is provided with an adjustment bolt 301. The adjustment bolt 301 passes through the slag frame 31 and the vertical lifting arm 302 from top to bottom and is rotatably connected to the vertical lifting arm 302. The adjustment bolt 301 is threadedly connected to the slag frame 31 and the vertical lifting arm 302.

[0038] The bulldozer blade 39 has a soil covering opening 303 inside. The bottom of the bulldozer blade 39 is inserted into the freshly broken soil, causing the broken soil to move upward along the bulldozer blade 39 and finally spray out from the soil covering opening 303 onto the straw and straw roots.

[0039] A soil pressing roller 12 is rotatably installed at the end of the partitioned cross frame 21 that is away from the crushing zone of the root breaking machine 11. The soil pressing roller 12 is parallel to the partitioned cross frame 21 and is lower than the height of the partitioned cross frame 21 and in contact with the ground.

[0040] Each conveyor belt 23 has a drive roller 24 at both ends inside. A transmission box 22 is fixedly installed on the side of the partition cross frame 21 away from the slag receiving box 27. The top ends of several drive rollers 24 pass through the partition cross frame 21 and are located in the transmission box 22. A drive wheel is fixedly installed on the top end of the drive rollers 24.

[0041] A drive motor 26 is installed above both ends of the partition crossbeam 21. A transmission belt 25 is installed on the pulley of the drive motor 26. The end of the transmission belt 25 away from the drive motor 26 passes through the transmission box 22 and connects to the drive wheel of the drive roller 24.

[0042] The slag receiving box 27 has a rotating pusher roller 29 inside, and several sets of slag-removing arms 201 are arrayed on the pusher roller 29. The slag-removing arms 201 are semi-circular. The center of the pusher roller 29 is connected to a transmission chain 202, and the other end of the transmission chain 202 is connected to the rotating shaft of the rotary tiller blade of the root breaker 11.

[0043] The slag receiving box 27 has a slag outlet 203 on the side near the partition cross frame 21. Several soil shaking arms 28 are rotatably installed on the bottom wall of the slag outlet 203, and the other end of the soil shaking arms 28 rests on the conveyor belt 23.

[0044] When in use, first attach the root breaker 11 to the back of the tractor. The tractor drives the rotary blades of the root breaker 11 to rotate at high speed to break the soil, straw and straw roots. Under the high speed rotation of the rotary blades, the straw and straw roots mixed with some soil will be thrown onto the slag collection box 27.

[0045] While the rotary tiller blades of the root breaker 11 are rotating at high speed, the pusher roller 29 is driven to rotate at high speed through the transmission chain 202. Several sets of scraper arms 201 rotate at high speed accordingly. When the scraper arms 201 are rotating, they will scrape back the soil, straw and straw roots that are thrown by the rotary tiller blades. Then, after being pushed by the scraper arms 201, the soil, straw and straw roots slide from the slag outlet 203 to several soil shaking arms 28. The broken soil will pass through the gaps of the soil shaking arms 28 and fall to the ground, while the straw and straw roots will slide onto the conveyor belt 23.

[0046] While the root breaking machine 11 is running, the two drive motors 26 drive their respective conveyor belts 23 to rotate, transporting the straw and straw roots on the conveyor belts 23 to the slag box 31. The slag box 31 is located in the gap of grain planting. After the straw and straw roots fall from the slag box 31, it can be ensured that the grain planting is not affected.

[0047] After the straw and straw roots fall into the slag box 31, they slide down the first slag guide plate 32 and the second slag guide plate 34 until they fall to the ground. As the root breaking machine 11 moves forward, the lifting arm 35 inserts into the soil. As the lifting arm 35 moves forward, it scoops up the soil fragments on the surface of the soil. The fragments pour out from the soil covering port 303 along the lifting arm 35. At this time, a large amount of the scooped-up fragments will cover the straw and straw roots that have just fallen, preventing the straw and straw roots from being exposed.

[0048] After the straw and straw roots are covered with soil, the soil pressing column 33 will rotate as the root breaking machine 11 moves forward through contact with the ground, so that several piercing columns 36 will pierce into the soil covering the straw and straw roots, forming air holes, which can accelerate the natural decomposition of the straw and straw roots. The telescopic structure of the lifting arm 35 and the guide arm 37 can be adjusted according to the terrain.

[0049] Finally, the rolling of the compaction roller 12 can compact the soil covering the straw and straw roots to a certain extent, preventing the loss of broken soil.

[0050] The soil-shaking arm 28 rests on the conveyor belt 23. As the conveyor belt 23 rotates, the soil-shaking arm 28 shakes, accelerating the falling of the broken soil and the sliding of the straw and straw roots.

[0051] Straw partitioning mechanism 2 and slag collection box 27: Located behind the rotary tiller's tillage area, it can effectively collect the debris, straw, straw roots and some soil carried by the rotary tiller, and transport them to the planting gaps via conveyor belt 23. This achieves precise partitioning and efficient collection of straw returning to the field, and avoids straw accumulation affecting sowing operations.

[0052] Design of the slag discharge frame 31 and the slag guide plate: The slag guide plate 1 32 and the slag guide plate 2 34 are designed to be inclined in opposite directions and do not contact each other, forming an effective flow guide gap. This ensures that the straw and straw roots can fall smoothly and centrally into the gap of the cultivation cage, preventing blockage and dispersion, and improving the positioning accuracy of straw return to the field.

[0053] Covering component and pressing column 33: The bulldozer plate 39 is inclined and can be inserted into the freshly broken soil. It can automatically scoop up the broken soil and cover the freshly fallen straw through the covering opening 303, forming a straw-soil composite covering layer, which not only avoids the straw being exposed, but also promotes subsequent decomposition. The pressing column 33 and the perforated column 36 on it can pierce the air holes on the covering surface, accelerate the aerobic decomposition of straw, and improve the returning effect to the field.

[0054] The perforated columns 36 on the outer wall array of the soil-pressing columns 33 adopt a quadrangular prism shape with an inclined top surface design. When rotating, they can both penetrate the soil to form air holes to accelerate straw decomposition and reduce soil resistance.

[0055] The design of the bulldozer blade 39 inserting into the freshly broken soil, combined with the spray structure of the covering port 303, forms a continuous action of "shoveling soil-lifting-covering", ensuring that the straw and straw roots are completely covered by the soil.

[0056] Height adjustment structure: The height of the bulldozer blade 39 off the ground can be precisely adjusted by rotating the control bolt 301 to adapt to different tillage depths and ground undulations, ensuring the stability and uniformity of the soil covering operation.

[0057] Power and transmission design: The straw-pushing roller 29 is linked to the rotary tiller shaft via a transmission chain 202, allowing it to rotate synchronously without additional power, saving energy and ensuring timely collection of straw fragments. The conveyor belt 23 is driven by the drive motor 26 through the transmission belt 25 and the drive roller 24, ensuring efficient and reliable power transmission.

[0058] Soil separation design: The soil shaking arm 28 set on the bottom wall of the slag outlet 203 rests on the conveyor belt 23. Its shaking action can effectively separate and screen out the broken soil, so that the straw and straw roots are sent away by the conveyor belt 23, reducing the ineffective transportation of soil, improving the transportation efficiency and the centralized processing capacity of straw.

[0059] Compactor roller 12: At the end of the operation, it lightly compacts the covered soil to prevent the cover soil from being blown away by the wind or washed away by rainwater, ensuring the stability of the cover layer and facilitating moisture retention and straw decomposition.

[0060] Attaching and starting: Attach the root breaker 11 to the back of the tractor, start the tractor, and drive the rotary tiller 11 to rotate at high speed to crush the soil, surface straw and straw roots.

[0061] Cruss collection and primary screening: The crushed material carried by the rotary tiller falls into the crushed material receiving box 27. The drive chain 202 drives the straw pushing roller 29 to rotate, and the crushed material scraping arm 201 on it scrapes the crushed material to the crushed material outlet 203. The soil falls back to the ground through the gap of the shaking soil shaking arm 28, while the straw and straw roots slide onto the conveyor belt 23.

[0062] Straw conveying and directional feeding: The drive motor 26 drives the conveyor belt 23 to operate through the transmission belt 25, conveying the straw and straw roots backward to the slag box 31; the slag is guided by the first slag guide plate 32 and the second slag guide plate 34, and falls precisely into the gap of the tillage cage.

[0063] Automatic soil covering and perforation: The bulldozer blade 39 is inserted into the broken soil in front, and as the machine moves forward, it shovels up the broken soil and pours it through the soil covering port 303 to cover the straw and straw roots that have just fallen; the soil pressing column 33 rolls behind it, and the perforating column 36 on it pierces the air holes in the soil covering surface.

[0064] Final compaction and leveling: The compaction roller 12 rolls and compacts the covered area to ensure that the straw-soil cover layer is flat and stable, thus completing the entire root breaking, straw return to the field and soil covering operation.

[0065] The embodiments of the present invention have been described above, but the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of the present embodiments, all of which are within the protection scope of the present embodiments.
