Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a combined no-till deep tillage machine for grassland. Background Technology

[0002] No-till deep tillage combined with land preparation is an important piece of equipment in modern grassland maintenance and improvement. Its core function is to complete the deep loosening of compacted soil and the leveling and compaction of the surface in a single pass. Deep tillage can break up the plow pan and improve soil permeability, while the subsequent compaction is crucial for restoring surface flatness, compacting loose soil, and promoting close contact between the grass roots and the soil.

[0003] In existing land preparation equipment, the compaction devices typically use metal rollers or compaction wheels with fixed weight and shape. This design provides a constant compaction effect on the ground. However, in actual grassland operations, soil conditions vary greatly; for example, soil moisture, density, and the degree of looseness after deep loosening all differ significantly.

[0004] For moist or heavy clay soils, a greater compaction force is required to achieve the desired compaction effect; however, for dry and loose soils, excessive compaction force may lead to excessive soil compaction, which is detrimental to pasture growth. Existing fixed compaction devices cannot adjust their compaction capacity according to these changing working conditions, resulting in poor operational adaptability and difficulty in achieving optimal land preparation quality under all conditions, thus affecting pasture recovery and growth.

[0005] Therefore, this utility model proposes a grassland no-till deep tillage combined land preparation machine to overcome the shortcomings of the existing technology. Utility Model Content

[0006] In view of the problems in the existing grassland no-till deep tillage combined tillage machine, the compaction effect of the compaction device is fixed and cannot be adjusted according to changes in soil moisture and type, resulting in poor operational adaptability and unstable tillage quality. The present invention aims to provide a grassland no-till deep tillage combined tillage machine with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a combined no-till deep tillage machine for grassland, comprising: a tractor, a passive connector connected to the tractor, an active connector inserted into the passive connector, a bracket fixed to the active connector, and deep tillage teeth installed on the bracket; and a compaction assembly disposed on the bracket.

[0008] The structure of the pressure ballast assembly includes a rotating rod, an airbag fixedly connected to the rotating rod, and a rubber outer layer sleeved on the outside of the airbag. The airbag is a hollow, inflatable structure and is provided with an inflation port for connecting to an external air source.

[0009] Furthermore, the compaction assembly is rotatably connected to the bottom of the support via its rotating rod, and its overall position is located behind the deep loosening teeth along the forward direction of the land leveling machine.

[0010] Preferably, the active contact block has an internal mounting groove. The active contact block also includes a push block slidably connected inside the mounting groove, a spring piece that provides a reset spring force to the push block, a paddle connected to the push block, and a limiting rod connected to the push block. The limiting rod is pluggably engaged with the passive contact block. By operating the paddle, the push block and the limiting rod are driven to move, thereby realizing the rapid locking or separation of the active contact block and the passive contact block.

[0011] Preferably, the outer rubber layer has a through hole for the inflation port to pass through. This structural design allows the inflation port to pass through the outer rubber layer and be exposed to the outside, which facilitates inflation and deflation operations without affecting the complete wrapping and protection of the airbag by the outer rubber layer.

[0012] Preferably, the passive connector has a plug hole adapted to the limiting rod, and the end of the limiting rod is inserted into the plug hole, forming a stable hole-rod plug-in locking structure, which improves the reliability of the connection and the positioning accuracy.

[0013] Preferably, the spring is a prestressed elastic sheet, one end of which is fixed to the inner wall of the mounting groove, and the other end is connected to the push block. It can automatically push the push block to reset after the paddle is released, thereby realizing the automation of locking.

[0014] Preferably, the sliding direction of the push block is perpendicular to the axial direction of the limiting rod. This orthogonal motion conversion design allows the pressing force applied to the paddle to be efficiently converted into a horizontal pulling action of the limiting rod, making the operation labor-saving and the transmission direct.

[0015] This utility model has the following beneficial effects: 1. In this utility model, by setting an inflatable and deflated airbag and utilizing the rubber outer layer of the airbag to contact the ground, the problem of fixed structure and inability to flexibly adjust the compaction effect according to soil conditions in the prior art of compaction devices is solved. This achieves the technical effect of being able to easily adjust the pressure on the ground, thereby realizing the best compaction and leveling of different soils, and improving the quality and adaptability of the operation.

[0016] 2. In this utility model, by setting a quick locking and unlocking mechanism composed of a spring, a push block, a paddle, and a limit rod, the problem of the existing technology where the working parts are usually connected by bolts, and the disassembly and installation process is cumbersome, time-consuming and labor-intensive is solved. It achieves the technical effect of quickly disassembling and assembling working parts such as deep loosening teeth without tools, greatly simplifying the maintenance and replacement process, significantly improving work efficiency and reducing labor intensity.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] Example: Please refer to Figures 1 to 3 This utility model provides a combined no-till deep tillage machine for grassland, which aims to solve the problems of difficult adjustment of compaction effect and cumbersome replacement of working parts of existing grassland tillage machines.

[0021] like Figure 1As shown, the grassland no-till deep tillage combined tillage machine includes a tractor 1, which provides forward power and traction for the whole machine; a passive connecting block 2 is located at the rear of the tractor 1, serving as a connecting component to receive the work implements behind it; the front end of the active connecting block 3 is inserted into the interior of the passive connecting block 2, enabling quick docking between the work implements and the traction part; a bracket 9 is fixedly connected to the rear of the active connecting block 3, which is used to install and support the deep tillage work components; and deep tillage teeth 10 are fixedly connected to the bottom of the bracket 9, which are used to insert into the soil for deep tillage operations.

[0022] like Figure 2 As shown, to enable quick assembly and disassembly of the active contact block 3 and the passive contact block 2, the active contact block 3 has an internal mounting groove 4; the push block 6 is slidably connected inside the mounting groove 4; the spring piece 5 is disposed inside the mounting groove 4, one end of the spring piece 5 is fixedly connected to one side inside the mounting groove 4, and the other side of the spring piece 5 is fixedly connected to the push block 6, the spring piece 5 is used to provide a reset spring force for the push block 6; the top of the push block 6 is fixedly connected to a paddle 7, the paddle 7 is exposed outside the mounting groove 4 for easy pressing operation, and is used for manual operation of the push block 6 sliding; one side of the push block 6 is fixedly connected to a limit rod 8, the limit rod 8 is pluggably inserted into the interior of the passive contact block 2, and is used to lock or unlock the active contact block 3 and the passive contact block 2.

[0023] Specifically, when disassembly is required, pressing the lever 7 causes the push block 6 to slide within the mounting groove 4 and compress the spring 5. The sliding of the push block 6 causes the limiting rod 8 on its side to disengage from the inside of the passive connecting block 2. At this time, the active connecting block 3 and the passive connecting block 2 are unlocked, and the active connecting block 3 can be pulled out. During installation, the active connecting block 3 is inserted into the passive connecting block 2, and the spring 5 rebounds to push the push block 6 to reset, thereby causing the limiting rod 8 to automatically insert into the inside of the passive connecting block 2 to achieve locking.

[0024] To solve the above-mentioned technical problems, the grassland no-till deep tillage combined tillage machine also includes a compaction assembly consisting of a rotating rod 13, an air bag 12 and a rubber outer layer 11, and the compaction assembly forms a specific structural fit and connection relationship with the aforementioned support 9.

[0025] Please refer to the following carefully. Figure 1 and Figure 3 The tamping assembly includes a rotating rod 13, which is rotatably connected to the bottom of the support 9. Its function is to serve as the rotation axis of the tamping assembly, allowing the tamping assembly to rotate with the terrain. An airbag 12 is fixedly connected to the middle of the rotating rod 13. The airbag 12 has a hollow structure and is used to adjust its outer diameter by changing the volume of the internal gas. A rubber outer layer 11 is sleeved on the outside of the airbag 12. The rubber outer layer 11 has wear-resistant properties and is used to directly contact the ground and protect the internal airbag 12.

[0026] To adjust the pressure effect, an inflation port 14 is provided on one side of the airbag 12. The inflation port 14 is used to connect to an external inflation or deflation device. By inflating or deflating gas into the airbag 12, the degree of expansion of the airbag 12 is changed, thereby changing the overall diameter of the rubber outer layer 11, and thus adjusting the contact area and pressure between the pressure assembly and the ground.

[0027] In a preferred embodiment, the outer rubber layer 11 has a through hole through which the inflation port (14) passes. The design of the through hole allows the inflation port 14 to pass through the outer rubber layer 11 and be exposed to the outside, which facilitates inflation and deflation operations, while not affecting the overall wrapping and protection of the airbag 12 by the outer rubber layer 11.

[0028] The compaction assembly is positioned behind the subsoil teeth 10 along the forward direction of the tillage machine. This layout ensures that after the subsoil teeth 10 complete the subsoiling operation, the compaction assembly can immediately compact and level the loose soil, forming a continuous operation process.

[0029] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, to make the connection between the limiting rod 8 and the passive connecting block 2 more secure and reliable, please refer to... Figure 2 The passive contact block 2 has a plug hole that matches the limiting rod 8. The end of the limiting rod 8 is plugged into the passive contact block 2 through the plug hole. This hole-rod matching structure provides precise positioning and effective locking.

[0030] As another preferred embodiment, in order to make the operation of the paddle 7 more convenient, the paddle 7 is exposed outside the mounting groove 4 for easy pressing operation. The operator can press the paddle 7 directly without using tools, so as to achieve quick assembly and disassembly.

[0031] As a further preferred embodiment, in order to enable the spring plate 5 to stably push the push block 6 to achieve automatic locking, the spring plate 5 is an elastic sheet. In its natural state, it applies a pushing force to the push block 6 to keep the limiting rod 8 and the passive connecting block 2 in an inserted state. When the active connecting block 3 is inserted into the passive connecting block 2, the guide end of the limiting rod 8 will first compress the spring plate 5. After passing the insertion hole, the rebound force of the spring plate 5 will push the push block 6 and the limiting rod 8 to automatically lock into the insertion hole.

[0032] As a specific limitation on the installation structure of the spring piece 5, one end of the spring piece 5 is fixed to the inner side wall of the mounting groove 4, and the other end is fixed to the side wall of the push block 6. This connection method ensures the effective transmission of elastic force.

[0033] As a limitation on the movement of the push block 6, the sliding direction of the push block 6 is perpendicular to the axial direction of the limiting rod 8. This orthogonal motion design allows the vertical force of pressing the paddle 7 to be efficiently converted into the horizontal unlocking movement of the limiting rod 8.

[0034] Working principle: When deep tillage is carried out, the tractor 1 moves forward and drives the entire machine to move through the connection between the passive connecting block 2 and the active connecting block 3; the deep tillage teeth 10 at the bottom of the support 9 are inserted into the soil to carry out deep tillage of the grassland; the compaction assembly located behind the deep tillage teeth 10 rolls accordingly, and the rubber outer layer 11 on it compacts and flattens the soil that has been deep tilled.

[0035] When the tamping effect needs to be adjusted, the operator can inflate or deflate the airbag 12 through the inflation port 14. Inflating the airbag 12 causes it to expand, increasing the diameter of its outer rubber layer 11, which reduces the contact area between the tamping assembly and the ground, thus increasing the pressure per unit area and achieving strong tamping. Deflating the airbag 12 causes it to contract, reducing the diameter of the outer rubber layer 11, increasing the contact area with the ground, and decreasing the pressure per unit area, thus achieving mild tamping. In this way, the problem of the fixed effect of traditional tamping devices is solved.

[0036] When it is necessary to replace the deep loosening tooth 10 or disassemble the tool, the operator presses the lever 7 exposed outside the mounting groove 4; the lever 7 drives the push block 6 to slide in the mounting groove 4 and compresses the spring 5; the sliding of the push block 6 causes the limit rod 8 fixed on its side to disengage from the insertion hole of the passive connector 2, thereby releasing the locking state between the active connector 3 and the passive connector 2; at this time, the active connector 3, together with the bracket 9 and the deep loosening tooth 10 behind it, can be pulled out from the passive connector 2 to complete the disassembly; during installation, simply align the active connector 3 and insert it into the passive connector 2, the guide end of the limit rod 8 will first compress the spring 5, when the active connector 3 is inserted into place, the elastic force of the spring 5 will automatically push the push block 6 and the limit rod 8 to reset, so that the limit rod 8 is locked into the insertion hole, realizing quick automatic locking, which solves the problem of cumbersome disassembly and assembly of traditional bolt connections.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
