Description

Technical Field

[0001] The invention relates to the technical field of rotary tillers, in particular to a detachable rotary tiller. Background Art

[0002] A rotary tiller is a tilling machine that is used in conjunction with a tractor to complete plowing and harrowing operations. It is widely used because of its strong soil crushing ability and flat surface after plowing. It can also chop up the root stubble buried below the surface, facilitating the operation of the seeder and providing a good seed bed for later sowing.

[0003] In rotary tillage, the soil is typically compacted directly without pretreatment. While existing detachable rotary tillers enable quick blade replacement through modular design, their functionality is still limited to a single tillage operation, requiring additional equipment to complete the loosening and compaction processes. Direct tillage without loosening the soil can easily lead to uneven soil particle fragmentation, affecting its air permeability and water retention, hindering crop growth. Untreated soil is also prone to soil erosion during rainfall or irrigation, further impacting soil quality and crop yields.

[0004] Therefore, it is urgent to improve the detachable rotary tiller to solve the above-mentioned problems. Summary of the Invention

[0018] Compared with the prior art, the present invention provides a detachable rotary tiller with the following beneficial effects:

[0019] 1. The present invention drives the connecting seat to move by the swing of the swing arm. The movable rod under the connecting seat slides in the limit plate. The movable rod drives the loosening rod to move up and down through the fixed plate and the cross bar, thereby achieving early crushing of the surface soil.

The multiple gravity blocks inside the roller provide stable pressure during the rotation process, and cooperate with the compaction action of the pressure blocks to make the compaction degree of the soil more uniform. Proper compaction can reduce large pores in the soil and prevent the rapid loss of water and nutrients. At the same time, it can ensure that the soil has a certain air permeability, improve the compactness and stability of the soil, and also improve the consistency and efficiency of the operation process.

[0021] 3. The present invention automatically controls the liquid suction and spraying actions of the spraying structure by utilizing the up and down movement of the movable rod, so that the pump housing, pump rod and nozzle evenly spray the treatment agent on the surface of the soil after plowing, thereby improving the penetration effect and utilization rate of the treatment agent, not only further optimizing the soil quality, but also being able to add fertilizers, pesticides or other soil improvers as needed to improve the fertility and disease resistance of the soil.

[0022] 4. The present invention synchronizes the loosening device and the compacting structure through a driving mechanism. The loosening device pre-loosens the soil before rotary tillage, destroys the hard crust and compacted layer on the soil surface, reduces the resistance during rotary tillage, and enables the rotary tiller to penetrate the soil more easily, plowing the soil more evenly and finely. At the same time, it also creates good conditions for the subsequent operation of the compacting structure, making the compacted soil more compact and flat, improving the overall quality of the soil, and providing a more suitable environment for crop growth.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figures 1 to 8 In this embodiment, a detachable rotary tiller includes a rotary tillage mechanism 1 that can be detachably connected to the outside of a tractor. The rotary tillage mechanism 1 consists of a frame 11, a side plate 12, a rotary tillage shaft 13 and a rotary tillage blade 14. A loosening device 2 for pre-loosening the soil before rotary tillage is provided on the outside of the side plate 12 and the frame 11. A compacting structure 3 for compacting the soil after plowing is provided on the outside of the frame 11. A driving mechanism 5 for linking the rotary tillage shaft 13, the loosening device 2 and the compacting structure 3 is provided on the outside of the side plate 12.

[0034] Among them, there are two side panels 12, and the two side panels 12 are fixedly connected to the outside of the frame 11 in a left-right symmetrical manner. The rotary tillage shaft 13 is rotatably connected to the inside of the two side panels 12. There are multiple rotary tillage blades 14, which are distributed on the outside of the rotary tillage shaft 13 at equal intervals. The top of the frame 11 is fixedly connected to a connecting frame 15, and the internal thread of the connecting frame 15 is connected to a connecting bolt 16 that can be connected to the tractor through the frame.

[0035] It should be noted that by adopting a detachable connection method, the rotary tillage mechanism 1 is connected to the tractor via the connecting bolts 16 on the connecting frame 15, making the installation and removal of the rotary tiller convenient and quick. When the rotary tiller is needed for operation, it can be quickly assembled and easily disassembled and stored after the operation is completed, saving time and labor costs. At the same time, the versatility of the device is improved, and it can be adapted to different models of tractors, thereby expanding the scope of use of the device.

[0036] See also Figures 1 to 3 In the present embodiment, the soil loosening device 2 comprises an articulated seat 21 fixedly connected to the top of the frame 11, a swing arm 22 hinged on the inside of the articulated seat 21, and a connecting seat 23 fixedly connected to the outside of the swing arm 22. The outside of the swing arm 22 is rotated and connected with a roller 29. The lower surface of the connecting seat 23 is provided with a mobile rod 25. The outside of the mobile rod 25 is fixedly connected with a fixed plate 26. The outside of the fixed plate 26 is fixedly connected with a cross bar 27. The bottom of the cross bar 27 is fixedly connected with a soil loosening rod 28. The inside of the connecting seat 23 is provided with an adjustment structure extending to its outside. Several soil loosening rods 28 are distributed at equal intervals at the bottom of the cross bar 27 in turn, which increases the contact area between the soil loosening rod 28 and the soil. It is possible to crush the soil on a larger scale simultaneously, thereby improving soil loosening efficiency. Moreover, the equal-interval distribution makes soil fragmentation more uniform, which is conducive to subsequent rotary tillage and crop growth, and provides a good soil environment for crop root systems.

[0037] The outside of the side plate 12 is fixedly connected to a limit plate 24 that is compatible with the moving rod 25. The moving rod 25 is slidably connected to the inside of the limit plate 24. There are a plurality of loosening rods 28, which are distributed at equal intervals at the bottom of the cross bar 27. A tension spring 210 is fixedly connected between the swing arm 22 and the frame 11. The tension spring 210 connects the swing arm 22 and the frame 11. During the swinging process of the swing arm 22, the tension spring 210 plays a role in buffering and resetting. When the swing arm 22 swings outward under the action of the eccentric weight 57, the tension spring 210 is stretched, storing elastic potential energy. When the eccentric weight 57 continues to rotate and the force acting on the swing arm 22 decreases, the elastic potential energy of the tension spring 210 is released, helping the swing arm 22 to quickly reset, making the swinging of the swing arm 22 more stable and continuous, and improving the working stability of the loosening rod 28.

[0038] Specifically, the adjustment structure includes an adjustment screw 211 that is rotatably connected to the inside of the connecting base 23 and a knob 212 that is fixedly connected to one end of the adjustment screw 211. The external thread of the adjustment screw 211 is connected to a moving block 213. The outside of the moving block 213 and the top of the moving rod 25 are hinged with a connecting rod 214, and the connecting rod 214 is distributed outside the connecting base 23 in an oblique shape. By rotating the adjustment screw 211 by rotating the knob 212, the moving block 213 is driven to slide in the connecting base 23, and then the moving rod 25 is driven up and down by the connecting rod 214, thereby conveniently adjusting the working depth of the loosening rod 28. The loosening depth can be flexibly adjusted according to different soil conditions and operating requirements, thereby improving the adaptability of the equipment. At the same time, the sliding connection between the back slider of the moving block 213 and the chute in the connecting base 23 ensures the stability and accuracy of the movement of the moving block 213.

[0039] It should be noted that the moving block 213 is slidably connected to the inside of the connecting seat 23 through the adjusting screw 211. The back of the moving block 213 is fixedly connected with a slider extending to the inside of the connecting seat 23. The inside of the connecting seat 23 is provided with a sliding groove adapted to the slider, and the slider and the sliding groove are slidably connected.

[0040] See also Figure 1 、 Figures 4 and 5 In this embodiment, the compaction structure 3 includes two mounting blocks 31 fixedly connected to the outside of the side plate 12 and rollers 32 rotatably connected to the inside of the two mounting blocks 31. A connecting ear 37 is fixedly connected to the inside of the roller 32, and a rotating shaft 38 is rotatably connected to the inside of the connecting ear 37. A weight block 39 is fixedly connected to the outside of the rotating shaft 38. A synchronization structure is provided on the outside of the roller 32. The synchronous rotation of the rollers 32 and the rotary tillage shaft 13 is achieved through a belt 36 transmission, ensuring close coordination between the compaction and rotary tillage operations. While the rotary tillage shaft 13 drives the rotary blade 14 to perform tillage, the rollers 32 can promptly compact the plowed soil, making the entire operation process consistent and efficient, improving work efficiency and quality, and reducing operation time and energy consumption.

[0041] Four pressure blocks 33 are fixedly connected to the outside of the roller 32. These four pressure blocks 33 are arranged in a ring-like pattern on the outside of the roller 32. A plurality of gravity blocks 39 are vertically positioned inside the roller 32. The four pressure blocks 33 are arranged in a ring-like pattern on the outside of the roller 32. As the roller 32 rotates, the gravity blocks 39 exert additional pressure on the roller 32 under the influence of centrifugal force, increasing the pressure exerted by the roller 32 on the soil and improving the compaction effect. Furthermore, the multiple gravity blocks 39 further enhance this pressure, making the soil more compacted and promoting the growth and fixation of crop roots.

[0042] Specifically, the synchronization structure includes a driven wheel 34 fixedly mounted on the outside of the roller 32 and a transmission wheel 35 fixedly mounted on the outside of the rotary tiller shaft 13. The external transmission of the transmission wheel 35 and the driven wheel 34 is connected by a belt 36, and the roller 32 and the rotary tiller shaft 13 rotate synchronously through the belt 36.

[0043] See also Figure 1 and Figure 6 In this embodiment, a spraying structure 4 for conveying the treatment agent is also provided on the outside of the side plate 12. The spraying structure 4 includes a pump casing 41 fixedly connected to the outside of the side plate 12 and a connecting block 46 fixedly connected to the top of the frame 11. A shunt pipe 47 is fixedly installed inside the connecting block 46. The bottom of the shunt pipe 47 is fixedly connected to a nozzle 48. The inside of the pump casing 41 is slidably connected to a pump rod 42 extending to the outside thereof. The top of the pump rod 42 is fixedly connected to an abutment block 43. A return spring 44 is fixedly connected between the abutment block 43 and the pump casing 41. The return spring 44 is surrounded and connected to the outside of the pump rod 42. One side of the pump casing 41 is fixedly connected to a liquid inlet pipe 45. The other side of the pump casing 41 is fixedly connected to a delivery pipe 49 between the shunt pipe 47. The abutment block 43 is located on the lower surface of the bottom end of the moving rod 25.

[0044] Among them, the delivery pipe 49 is connected to the external liquid storage tank. When the movable rod 25 moves upward, the abutment block 43 rises accordingly, and the return spring 44 pushes the pump rod 42 upward, forming a negative pressure inside the pump housing 41. The treatment agent is sucked into the pump housing 41 through the liquid inlet pipe 45, preparing for the next spraying. When the movable rod 25 moves downward, the abutment block 43 pushes the pump rod 42 downward, compressing the treatment agent in the pump housing 41. The treatment agent enters the diverter pipe 47 through the delivery pipe 49 and is ejected from the nozzle 48, evenly spraying it on the surface of the soil after plowing. This linkage method allows the spraying of the treatment agent to be closely coordinated with the loosening operation. The treatment agent is sprayed while the soil is loosened, which improves the use effect of the treatment agent and further improves the operation efficiency.

[0045] See also Figure 1 、 Figures 7 and 8In this embodiment, the drive mechanism 5 includes a dual-axis motor 51 disposed on the exterior of the side plate 12, a worm gear 52 fixedly mounted on the exterior of the rotary tiller shaft 13, and a mounting plate 55 fixedly connected to the exterior of the articulated seat 21. A worm 53, meshing with the worm gear 52, is fixedly connected to the output shaft at the bottom end of the dual-axis motor 51. A connecting shaft 56 extending therefrom is rotatably connected to the interior of the mounting plate 55. An eccentric weight 57 is fixedly mounted on the exterior of the connecting shaft 56, which is in rolling engagement with the exterior of the roller 29. The swing arm 22 and the connecting seat 23 are connected to the upper surface of the frame 11 via the eccentric weight 57, which reciprocates and swings. The dual-axis motor 51 drives the worm gear 52 and worm gear 53 to rotate the rotary tiller shaft 13, thereby rotating the rotary blade 14 and performing the rotary tilling operation. At the same time, the meshing transmission of the transmission gear 54 and the driven gear 58 drives the connecting shaft 56 and the eccentric block 57 to rotate, thereby driving the loosening device 2, the compacting structure 3 and the spraying structure 4 to work. The compact structure can reasonably distribute the power of a power source to multiple operating components, realizing the coordinated operation of rotary tillage, loosening, spraying treatment agent and compaction, thereby improving the overall working efficiency and power utilization of the equipment. A protective cover is detachably connected to the outside of the driving mechanism 5.

[0046] Among them, the end of the connecting shaft 56 away from the mounting plate 55 is fixedly connected to the driven gear 58, and the top output shaft of the dual-axis motor 51 is fixedly connected to the transmission gear 54 that meshes with the driven gear 58. The dual-axis motor 51 is fixedly installed on the outside of the side plate 12 through the motor base.

[0047] The working principle of the above embodiment is:

[0048] When in use, the frame 11 is detachably connected to the outside of the tractor through the connecting frame 15 and the connecting bolts 16 on the top. The dual-axis motor 51 in the driving mechanism 5 is started by the controller, and the output shaft at the top of the dual-axis motor 51 drives the transmission gear 54 to rotate. The transmission gear 54 drives the driven gear 58 engaged therewith to rotate, thereby driving the connecting shaft 56 to rotate. The eccentric block 57 on the connecting shaft 56 rotates accordingly, and the eccentric block 57 is rollingly connected to the roller 29, so that the swing arm 22 swings back and forth around the articulated seat 21.

[0049] The swing arm 22 swings to drive the connecting seat 23 to move, and the moving rod 25 under the connecting seat 23 slides in the limit plate 24. The moving rod 25 drives the loosening rod 28 to move up and down through the fixed plate 26 and the cross bar 27, thereby achieving early crushing of the surface soil. By turning the knob 212 to rotate the adjusting screw 211, the moving block 213 on the adjusting screw 211 slides along the connecting seat 23 under the cooperation of the slider and the slide groove. The moving block 213 drives the moving rod 25 to move up and down through the connecting rod 214, thereby changing the position of the loosening rod 28;

[0050] The output shaft at the bottom end of the dual-shaft motor 51 drives the worm 53 to rotate, and the worm 53 engages with the worm wheel 52 fixed on the rotary tiller shaft 13 to drive the rotary tiller shaft 13 to rotate, and the multiple rotary tillers 14 on the rotary tiller shaft 13 rotate accordingly to till the soil;

[0051] The synchronization structure links the compaction structure 3 with the rotary tillage mechanism 1. When the rotary tillage shaft 13 rotates, the transmission wheel 35 on it drives the driven wheel 34 on the roller 32 to rotate through the belt 36, thereby rotating the roller 32; the connecting ear 37 in the roller 32 rotates to connect the rotating shaft 38, and the weight block 39 is fixed on the rotating shaft 38. When the roller 32 rotates, the weight block 39 generates additional pressure on the roller 32 under the action of centrifugal force, and the multiple pressure blocks 33 outside the roller 32 compact the soil after plowing;

[0052] When the movable rod 25 moves downward, its bottom end abuts the abutment block 43, pushing the pump rod 42 to slide in the pump housing 41, compressing the treatment agent in the pump housing 41, and the treatment agent enters the diversion pipe 47 through the delivery pipe 49 and is then sprayed out from the nozzle 48, thereby realizing the delivery and spraying of the soil treatment agent. When the movable rod 25 moves upward, the return spring 44 pushes the abutment block 43 and the pump rod 42 to reset, and the liquid inlet pipe 45 sucks in the treatment agent to prepare for the next spraying.

[0053] The installation method, connection method or setting method disclosed in this embodiment are all common mechanical connection methods, and can be implemented as long as they can achieve their beneficial effects. In addition, the electrical components appearing in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Technicians in this field can control the electrical components through simple programming, and the existing disclosed power connection technology is also common knowledge in this field, so the specific structural composition and working principle will not be described in detail in this embodiment.
