Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to a layered, low-disturbance deep tillage device adapted to soil hardness. Background Technology

[0002] The main function of deep tillage in agriculture is to loosen the soil, improve soil structure, enhance soil water retention capacity and crop lodging resistance, improve fertilizer utilization, and promote crop growth. Deep tillage is mostly carried out using deep tillage machines, which play a crucial role in deeply turning the soil and breaking up the plow pan, making them an important agricultural implement for conservation tillage. Referring to Chinese patent publication number "CN220693643U" entitled "A Staggered Deep Tillage Device and Deep Tillage Machine," this patent points out that existing deep tillage machines have a fixed arrangement of multiple deep tillage shovels, i.e., the shovel bodies are welded to the machine frame, resulting in a fixed spacing between the shovels in the X and Y axes. This makes it impossible to change the spacing between the shovels under different usage scenarios, leading to suboptimal shovel arrangement, fuel waste, and significant machine wear. However, the above equipment still suffers from problems such as a limited deep tillage range and cumbersome deep tillage height adjustment. To address these issues, we propose a layered, low-disturbance deep tillage device that adapts to soil hardness. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a layered, low-disturbance deep tillage device that adapts to soil hardness, thus solving the problems mentioned in the background section.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a layered, low-disturbance deep tillage device adapted to soil hardness, comprising a connecting arm, a positioning plate fixedly installed at the end of the connecting arm for mounting the connecting arm to a traction device, a deep tillage main shovel rotatably connected to the end of the connecting arm away from the positioning plate, a connecting frame fixedly installed at the end of the connecting arm, and a support spring fixedly installed between the connecting frame and the end of the deep tillage main shovel, and a rotating shaft rotatably connected between the deep tillage main shovel and the connecting arm, so that when the deep tillage main shovel comes into contact with hard rocks during the deep tillage process, it can be subjected to force and rotate along the rotating shaft to stretch the support spring;

[0005] The end of the deep tillage main shovel is fixedly equipped with an arc-shaped shovel blade. Both sides of the arc-shaped shovel blade are fixedly equipped with a limiting shaft. Multiple extension shovel blades are slidably connected to the outer side of the limiting shaft. Multiple positioning posts are fixedly installed on the outer side of the deep tillage main shovel. The interior of each of the multiple extension shovel blades is provided with a through hole that matches the positioning post. The positioning post is used to lock the corresponding extension shovel blade.

[0006] Preferably, the outer sides of the plurality of arc-shaped shovel blades are all provided with inclined surfaces.

[0007] Preferably, an arc-shaped arm is fixedly installed on the outer middle part of the deep loosening main shovel.

[0008] Preferably, both sides of the arc-shaped shovel are rotatably connected to a flipping baffle, and the flipping baffle is installed on the outside of the rotating shaft.

[0009] Preferably, a rear support rod is rotatably connected to both ends of the connecting arm, and a bulldozing shaft is rotatably connected between the ends of the two rear support rods. Multiple outer bushings are rotatably connected to the outer side of the bulldozing shaft, and multiple bulldozing rollers are fixedly installed on the outer side of the outer bushings. The multiple bulldozing rollers are used to flatten the deep-loosened soil surface as the outer bushings and the bulldozing shaft rotate.

[0010] Preferably, the rear support rod is internally rotatably connected to a positioning screw, which is used to assemble the rear support rod to the end of the connecting arm.

[0011] Preferably, a spring body is sleeved on the outer side of the rear support rod to apply pressure to the rear support rod and the bulldozer shaft.

[0012] Preferably, an assembly bushing is fixedly installed at the end of the connecting arm, a limit frame is rotatably connected inside the assembly bushing, a concave push frame is slidably installed inside the limit frame, and a transmission component is provided between the concave push frame and the deep loosening main shovel. When the deep loosening main shovel comes into contact with the hard rock during the deep loosening process and rotates along the rotating shaft, the transmission component can drive the concave push frame to move down and insert into the soil, turning over the hard rock.

[0013] Preferably, the transmission assembly includes a winding shaft and a wire traction rope. An arc-shaped protective frame is fixedly installed at the top of the deep loosening main shovel. The wire traction rope passes around the outside of the winding shaft. One end of the wire traction rope is fixedly connected to the top of the concave push frame. The other end of the wire traction rope passes through the arc-shaped protective frame and is fixedly connected to the end of the deep loosening main shovel. The wire traction rope is slidably connected to the arc-shaped protective frame.

[0014] Preferably, a return spring is connected between the assembly bushing and the concave push bracket, and a return torsion spring is connected between the assembly bushing and the limiting bracket.

[0015] This invention provides a layered, low-disturbance deep tillage device adapted to soil hardness. Compared with existing technologies, it has the following advantages:

[0016] (1) This layered low-disturbance deep tillage device adaptable to soil hardness, through the cooperation of the deep tillage main shovel and the extension shovel, the deep tillage main shovel can increase the deep tillage range through multiple extension shovels connected to the outside during the deep tillage process. When it is necessary to deep tillage the soil at different depths, the height position of the extension shovel can be adjusted by rotating the extension shovel and letting it slide along the limiting shaft to the corresponding positioning column, thereby realizing layered deep tillage. This ensures the deep tillage effect while improving the ease of use and the deep tillage range of the equipment, and makes it easier to break the plow pan.

[0017] (2) The layered low-disturbance deep loosening device adapted to soil hardness, through the setting of the concave push frame, when the connecting arm runs with the traction equipment, the end of the concave push frame is located above the ground. When the deep loosening main shovel comes into contact with hard rocks during the deep loosening process and is subjected to force and rotates, it can drive the concave push frame to slide down inside the limit frame through the steel wire traction rope, so that the concave push frame inserts into the ground and digs out the hard rocks as the traction equipment continues to run, effectively improving the use effect of the equipment.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-8 The present invention provides two technical solutions, specifically including the following embodiments:

[0029] Example 1: In this embodiment of the invention, a layered low-disturbance deep tillage device adapted to soil hardness includes a connecting arm 1. A positioning plate 2 is fixedly installed at the end of the connecting arm 1 for installing the connecting arm 1 to a traction device. A deep tillage main shovel 3 is rotatably connected to the end of the connecting arm 1 away from the positioning plate 2. A connecting frame 4 is fixedly installed at the end of the connecting arm 1, and a support spring 5 is fixedly installed between the connecting frame 4 and the end of the deep tillage main shovel 3. A rotating shaft 302 is rotatably connected between the deep tillage main shovel 3 and the connecting arm 1, so that when the deep tillage main shovel 3 comes into contact with hard rocks during the deep tillage process, it can be subjected to force and rotate along the rotating shaft 302 to stretch the support spring 5.

[0030] In this embodiment of the invention, the traction device is an existing agricultural equipment. When assembling the connecting arm 1, the number of deep tillage devices and the assembly spacing can be selected according to the area of ​​the cultivated land, which will not be elaborated here.

[0031] In this embodiment of the invention, during operation, as the traction device drives the connecting arm 1 to perform deep loosening of the land, the end of the deep loosening main shovel 3 can be inserted into the ground to loosen the soil. When the deep loosening main shovel 3 comes into contact with hard rocks during the loosening process, it can be rotated along the rotating shaft 302 under force, stretching the support spring 5 until the deep loosening main shovel 3 passes over the hard rocks and then resets through the support spring 5, thus avoiding damage to the deep loosening main shovel 3 and improving the protection of the equipment.

[0032] In this embodiment of the invention, specifically, an arc-shaped shovel 6 is fixedly installed at the end of the deep tillage main shovel 3, and a limiting shaft 601 is fixedly installed on both sides of the arc-shaped shovel 6. Multiple extension shovels 7 are slidably connected to the outer side of the limiting shaft 601. Multiple positioning posts 8 are fixedly installed on the outer side of the deep tillage main shovel 3. The interior of each of the multiple extension shovels 7 is provided with through holes that are compatible with the positioning posts 8. The positioning posts 8 are used to lock the corresponding extension shovels 7.

[0033] In this embodiment of the invention, specifically, during the deep loosening process, the main shovel 3 can increase the deep loosening range through multiple extended shovel blades 7 connected to the outside. When deep loosening is required for soils at different depths, the extended shovel blades 7 can be rotated to disengage from the positioning post 8 along the limiting shaft 601. At this time, the extended shovel blades 7 can slide along the limiting shaft 601 until they reach a preset position, at which point the corresponding positioning post 8 is inserted into the through hole inside the extended shovel blade 7, thus completing the positioning of the extended shovel blades 7. In this way, it is easy to adjust the installation position of the extended shovel blades 7, thereby achieving layered deep loosening and improving the equipment's performance.

[0034] In this embodiment of the invention, the positioning of the extended blade 7 is achieved by the positioning column 8. When the equipment is running, as the extended blade 7 comes into contact with the soil, it can apply pressure to the deep loosening main shovel 3 and the rotating shaft 302. At this time, the positioning column 8 provides support, which can ensure the assembly stability of the extended blade 7 and facilitate the adjustment of the assembly position of the extended blade 7.

[0035] In this embodiment of the invention, specifically, the outer sides of the multiple arc-shaped shovel blades 6 are all opened as inclined surfaces, and an arc-shaped arm 301 is fixedly installed on the middle of the outer side of the deep loosening main shovel 3, which can ensure the deep loosening effect while reducing disturbance to the soil.

[0036] In this embodiment of the invention, specifically, both sides of the arc-shaped shovel 6 are rotatably connected with a flipping baffle 9, and the installation position of the flipping baffle 9 is located on the outside of the rotating shaft 302;

[0037] In this embodiment of the invention, specifically, when the baffle 9 is flipped, as the deep loosening main shovel 3 comes into contact with the soil, it can be tightly pressed against the outside of the positioning post 8 and the limiting shaft 601, preventing soil from entering between the extended shovel blade 7 and the limiting shaft 601, which would make subsequent cleaning difficult.

[0038] Example 2: Based on Example 1, a layered low-disturbance deep tillage device adapted to soil hardness includes a connecting arm 1. A positioning plate 2 is fixedly installed at the end of the connecting arm 1 for installing the connecting arm 1 to a traction device. A deep tillage main shovel 3 is rotatably connected to the end of the connecting arm 1 away from the positioning plate 2. A connecting frame 4 is fixedly installed at the end of the connecting arm 1, and a support spring 5 is fixedly installed between the connecting frame 4 and the end of the deep tillage main shovel 3. A rotating shaft 302 is rotatably connected between the deep tillage main shovel 3 and the connecting arm 1, so that when the deep tillage main shovel 3 comes into contact with hard rocks during the deep tillage process, it can be subjected to force and rotate along the rotating shaft 302 to stretch the support spring 5.

[0039] The traction equipment is existing agricultural equipment. When assembling the connecting arm 1, the number of deep tillage devices and the assembly spacing can be selected according to the area of ​​the cultivated land, which will not be elaborated here.

[0040] In this embodiment of the invention, during operation, as the traction device drives the connecting arm 1 to perform deep loosening of the land, the end of the deep loosening main shovel 3 can be inserted into the ground to loosen the soil. When the deep loosening main shovel 3 comes into contact with hard rocks during the loosening process, it can be rotated along the rotating shaft 302 under force, stretching the support spring 5 until the deep loosening main shovel 3 passes over the hard rocks and then resets through the support spring 5, thus avoiding damage to the deep loosening main shovel 3 and improving the protection of the equipment.

[0041] An arc-shaped shovel 6 is fixedly installed at the end of the deep tillage main shovel 3. A limiting shaft 601 is fixedly installed on both sides of the arc-shaped shovel 6, and multiple extension shovels 7 are slidably connected to the outer side of the limiting shaft 601. Multiple positioning pins 8 are fixedly installed on the outer side of the deep tillage main shovel 3. The interior of each extension shovel 7 is provided with through holes that are compatible with the positioning pins 8. The positioning pins 8 are used to lock the corresponding extension shovels 7.

[0042] During the deep tillage process, the main shovel 3, through multiple extended shovel blades 7 connected to the outside, can increase the range of deep tillage. When deep tillage is required for soil at different depths, the extended shovel blades 7 can be rotated to disengage from the positioning pins 8 along the limiting shaft 601. At this time, the extended shovel blades 7 can slide along the limiting shaft 601 until they reach the preset position, at which point the corresponding positioning pins 8 are inserted into the through holes inside the extended shovel blades 7, thus completing the positioning of the extended shovel blades 7. In this way, it is easy to adjust the installation position of the extended shovel blades 7, thereby achieving layered deep tillage and improving the use effect of the equipment.

[0043] In this embodiment of the invention, the positioning of the extended blade 7 is achieved by the positioning column 8. When the equipment is running, as the extended blade 7 comes into contact with the soil, it can apply pressure to the deep loosening main shovel 3 and the rotating shaft 302. At this time, the positioning column 8 provides support, which can ensure the assembly stability of the extended blade 7 and facilitate the adjustment of the assembly position of the extended blade 7.

[0044] The outer sides of multiple arc-shaped shovel blades 6 are all inclined surfaces, and an arc-shaped arm 301 is fixedly installed on the middle of the outer side of the deep loosening main shovel 3, which can ensure the deep loosening effect while reducing disturbance to the soil.

[0045] In this embodiment of the invention, specifically, both sides of the arc-shaped shovel 6 are rotatably connected with a flipping baffle 9, and the installation position of the flipping baffle 9 is located on the outside of the rotating shaft 302;

[0046] When the baffle 9 is flipped, it can be tightly pressed against the outside of the positioning post 8 and the limiting shaft 601 when the deep loosening main shovel 3 comes into contact with the soil, preventing soil from entering between the extended shovel 7 and the limiting shaft 601 and making subsequent cleaning difficult.

[0047] Both ends of the connecting arm 1 are rotatably connected to the rear support rods 10. The ends of the two rear support rods 10 are rotatably connected to the bulldozing shaft 13. Multiple outer bushings 131 are rotatably connected to the outer side of the bulldozing shaft 13, and multiple bulldozing rollers 132 are fixedly installed on the outer side of the outer bushings 131. The multiple bulldozing rollers 132 are used to flatten the deep-loosened soil surface as the outer bushings 131 and the bulldozing shaft 13 rotate.

[0048] In this embodiment of the invention, specifically, a positioning screw 11 is rotatably connected inside the rear support rod 10, and the positioning screw 11 is used to assemble the rear support rod 10 to the end of the connecting arm 1;

[0049] In this embodiment of the invention, specifically, a spring body 12 is sleeved on the outer side of the rear support rod 10 to apply pressure to the rear support rod 10 and the bulldozer shaft 13;

[0050] With the cooperation of the rear support rod 10 and the bulldozing axle 13, when the traction equipment drives the connecting arm 1 to run, the multiple bulldozing axles 13 installed on the outside of the bulldozing axle 13 can contact the ground and roll along the ground to achieve the leveling of the land and further improve the use effect of the equipment.

[0051] An assembly bushing 18 is fixedly installed at the end of the connecting arm 1. A limit frame 14 is rotatably connected inside the assembly bushing 18. A concave push frame 15 is slidably installed inside the limit frame 14. A transmission component is provided between the concave push frame 15 and the deep loosening main shovel 3. When the deep loosening main shovel 3 comes into contact with hard rocks during the deep loosening process and rotates along the rotating shaft 302, the transmission component can drive the concave push frame 15 to move down and insert into the soil to turn over the hard rocks.

[0052] In this embodiment of the invention, specifically, the transmission assembly includes a winding shaft 17 and a wire traction rope 171. An arc-shaped protective frame 16 is fixedly installed at the top of the deep loosening main shovel 3. The wire traction rope 171 passes around the outside of the winding shaft 17. One end of the wire traction rope 171 is fixedly connected to the top of the concave push frame 15, and the other end of the wire traction rope 171 passes into the inside of the arc-shaped protective frame 16 and is fixedly connected to the end of the deep loosening main shovel 3. The wire traction rope 171 is slidably connected to the arc-shaped protective frame 16.

[0053] In this embodiment of the invention, specifically, a return spring 181 is connected between the assembly bushing 18 and the concave push bracket 15, and a return torsion spring 182 is connected between the assembly bushing 18 and the limiting bracket 14.

[0054] In this embodiment of the invention, specifically, the reset spring 181 is used to drive the concave pusher 15 to reset, and the reset torsion spring 182 is used to drive the limit frame 14 to reset.

[0055] In this embodiment of the invention, when the connecting arm 1 is running with the traction equipment, the end of the concave push frame 15 is located above the ground. When the deep loosening main shovel 3 comes into contact with the hard rock during the deep loosening process and is subjected to force to rotate, the concave push frame 15 can be driven to slide down inside the limit frame 14 through the steel wire traction rope 171, so that the concave push frame 15 is inserted into the ground, and with the continuous operation of the traction equipment, the hard rock is dug out, which effectively improves the use effect of the equipment.

[0056] In this embodiment of the invention, specifically, in order to ensure the digging effect of the concave pusher 15 on hard rocks, the end shape of the concave pusher 15 can be set to arc shape, which will not be elaborated here;

[0057] In this embodiment of the invention, when the concave pusher 15 cannot be pushed after contacting the hard rock, it can drive the limiter 14 to rotate inside the assembly bushing 18 until it passes the hard rock and is reset by the reset torsion spring 182, thus ensuring continuous operation of the equipment while avoiding damage to the equipment.

[0058] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
