Description

Technical Field

[0001] This invention relates to the field of greenhouse planting equipment technology, specifically a soil loosening device for greenhouse planting. Background Technology

[0002] During greenhouse cultivation, soil is prone to compaction after repeated planting. Compacted soil is like a hardened block, with its original loose structure destroyed and soil particles tightly compressed together, making the gaps between soil particles extremely small. As a result, air cannot easily enter the soil, plant root cells are restricted from respiration, and thus crop growth is affected.

[0003] However, most existing soil loosening devices for greenhouse cultivation have fixed structures, making it difficult to flexibly adjust the loosening depth and range according to different soil conditions and planting needs. For example, when faced with severely compacted clay soil, fixed soil loosening plows are unable to effectively break up deep compacted layers, resulting in poor aeration of the deep compacted layers and affecting the subsequent normal growth of plants. Therefore, it is necessary to design a soil loosening device for greenhouse cultivation to solve the above problems.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0006] The technical solution adopted by this application to solve its technical problem is: a soil loosening device for greenhouse planting, including a crossbeam and a connecting frame, the connecting frame being installed on the crossbeam, and also including a plurality of first connecting plates and a plurality of adjusting boxes, each of the plurality of adjusting boxes having a second connecting plate fixed thereon, the second connecting plates being installed on the crossbeam at intervals with the first connecting plates by bolts, an intermediate plate sliding inside the adjusting box, a connecting plate being fixed at the lower end of the intermediate plate, and the lower end of the connecting plate extending to the lower part of the adjusting box and having a bucket-shaped soil loosening plow fixed thereon;

[0007] A bracket is fixed to one side of the adjustment box, and electric push rods are installed at both ends of the bracket. A top plate is installed at the output end of the electric push rod, and connecting rods are installed at both ends of the top plate. The lower end of the connecting rod extends into the adjustment box and connects to the intermediate plate.

[0008] Furthermore, the adjustment box is provided with a limiting groove, and the intermediate plate slides within the limiting groove.

[0009] Furthermore, guide rods are installed at both ends of the bracket, and the top plate is sleeved on the body of the guide rod and can move axially along the guide rod.

[0010] Furthermore, a horizontal plate slides on the upper end of each of the connecting plates, and the two ends of the adjusting box are provided with limiting holes, and the horizontal plate can move axially along the limiting holes;

[0011] Multiple adapter frames are installed on the other side of the horizontal plate, and each adapter frame is equipped with a vertical plate. Multiple vertical sliding holes are spaced apart on the horizontal beam. The vertical plate passes through the vertical sliding holes and can move axially along the vertical sliding holes.

[0012] Furthermore, the upper end of the connecting plate is provided with a transverse sliding hole adapted to the horizontal plate, and a first snap-fit ​​arc groove is provided in the transverse sliding hole. A plurality of first snap-fit ​​arc strips are fixed on the horizontal plate, and the first snap-fit ​​arc strips are inserted into the first snap-fit ​​arc grooves.

[0024] 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.

[0025] Please see Figure 1-6 This invention provides a technical solution: a soil loosening device for greenhouse planting, including a crossbeam 1, a connecting frame 2, a first connecting plate 3, and an adjusting box 4. The connecting frame 2 is a U-shaped steel structure, which is vertically installed on the central top surface of the crossbeam 1 by high-strength bolts. The bolt holes adopt a countersunk design to ensure that the installation surface is flat. The top of the connecting frame 2 is provided with a standard agricultural machinery interface, which can be quickly connected to external power equipment such as tractors. The interface adopts an anti-loosening buckle design to ensure a stable connection during operation. The adjusting box 4 is a metal box, and a second connecting plate 23 is welded to its top. Both the second connecting plate 23 and the first connecting plate 3 have bolt holes, and the two are fixed to the beam of the crossbeam 1 by galvanized bolts and anti-loosening washers.

[0026] The regulating box 4 has a limiting groove 5 inside, and a middle plate 7 slides in the limiting groove 5. The middle plate 7 is made of stainless steel. The lower end of the middle plate 7 is fixed with a connecting plate 8 by double-sided full welding. The vertical movement of the connecting plate 8 is synchronously transmitted to the bucket-shaped loosening plow 9 at the lower end through a rigid connection. Due to the guiding effect of the limiting groove 5 on the middle plate 7, the verticality error between the lifting trajectory of the bucket-shaped loosening plow 9 and the horizontal plane is ≤0.3°, ensuring precise control of the soil penetration depth. The bucket-shaped loosening plow 9 is made of spring steel forging. Its bucket-shaped structure can penetrate deep into the soil, breaking up large clumps of compacted soil into small pieces, thereby improving the aeration and permeability of deep soil.

[0027] A bracket 10 is welded to the side of the adjusting box 4. Electric push rods 11, model JLX-KT100, are bolted to both ends of the bracket 10. The two electric push rods 11 achieve a displacement accuracy of ±0.5mm through a synchronous controller to ensure that the soil penetration depth of multiple bucket-shaped loosening plows 9 is consistent. A top plate 12 is bolted to the output end of the electric push rod 11. The top plate 12 is a rectangular steel plate with connecting rods 13 welded to both ends. The connecting rods 13 are round steel structures, with their lower ends penetrating the interior of the adjusting box 4 and welded to the middle plate 7. Guide rods 14 are also welded to both ends of the bracket 10. The top plate 12 has through holes that match the guide rods 14 and is fitted onto the rod body of the guide rods 14. It can move axially along the guide rods 14 to ensure the stability of the movement of the top plate 12.

[0028] A transverse sliding hole 24 is provided at the upper end of the connecting plate 8, and a first locking arc groove 16 is provided inside the transverse sliding hole 24. A horizontal plate 15 slides on the connecting plate 8. The horizontal plate 15 is a long rectangular plate and slides within the transverse sliding hole 24. A first locking arc strip 17 is welded and fixed to its body. The first locking arc strip 17 and the first locking arc groove 16 are in clearance fit. When the horizontal plate 15 is assembled on the connecting plate 8, the first locking arc strip 17 is embedded into the first locking arc groove 16 to form a lock, which is used to withstand the transverse thrust generated by the equipment during the loosening process. The adjusting box 4 is provided with a limiting hole 6 for the horizontal plate 15 to move up and down, so that the horizontal plate 15 is not restricted by the adjusting box 4 during the up and down movement. An adapter frame 18 is bolted to the outside of the horizontal plate 15. The bolted connection facilitates the disassembly of the adapter frame 18. A detachable vertical plate 19 is installed inside the adapter frame 18 by bolts.

[0029] The vertical plate 19 is a rectangular steel plate with a vertical sliding hole 25 through the horizontal beam 1 at the top. A second locking arc groove 20 is provided in the vertical sliding hole 25, which forms a convex-concave fit with the second locking arc strip 21 welded and fixed on the vertical plate 19. When the vertical plate 19 moves up and down, the second locking arc strip 21 slides along the vertical sliding hole 25, thereby improving the stability of the vertical plate 19 during the up and down sliding process. An arc-shaped loosening plow 22 is welded and fixed at the lower end of the vertical plate 19. The arc-shaped loosening plow 22 is made of manganese steel and has an arc-shaped cutting edge on the surface in contact with the soil. It can turn over small clods of soil and further loosen and flatten the deep soil broken by the bucket-shaped loosening plow 9, reducing soil surface compaction and adapting to the loosening needs of different soils.

[0030] Working principle: When it is necessary to increase the soil loosening depth of the bucket-shaped loosening plow 9, the electric push rod 11 is connected to an external power source and started by the corresponding control button. The electric push rod 11 serves as a power source, and its output end begins to retract, driving the top plate 12, which is welded and fixed to it, to move downward along the guide rod 14. At this time, the guide rod 14 plays a stabilizing guiding role, so that the top plate 12 is not easy to deviate or shake during the movement. The movement of the top plate 12 is transmitted through the connecting rods 13 at both ends. The upper end of the connecting rod 13 is fixed to the top plate 12, and the lower end passes through the adjustment box 4 and is fixed to the middle plate 7. As the top plate 12 moves downward, the connecting rod 13 drives the middle plate 7 to slide downward in the limiting groove 5 inside the adjustment box 4. The limiting groove 5 limits the movement trajectory of the middle plate 7, so that it can only move in the vertical direction.

[0031] The lower end of the intermediate plate 7 is fixedly connected to the connecting plate 8. Therefore, the vertical movement of the intermediate plate 7 will be transmitted to the bucket-shaped loosening plow 9 through the connecting plate 8, so that the bucket-shaped loosening plow 9 will descend synchronously with the intermediate plate 7. This vertical movement of the bucket-shaped loosening plow 9 directly changes the depth of its contact with the soil, thereby realizing the adjustment of the loosening depth.

[0032] During the process of increasing the soil loosening depth of the bucket-shaped loosening plow 9, the connecting plate 8 also simultaneously drives the horizontal plate 15 to move downwards. At this time, as the horizontal plate 15 moves downwards, it drives the vertical plate 19 downwards through the adapter frame 18. The vertical plate 19 passes through the vertical sliding hole 25 on the crossbeam 1 and slides downwards along the vertical sliding hole 25, thereby increasing the soil loosening depth of the arc-shaped loosening plow 22 at its lower end. This simplifies the operation process of adjusting the height of the arc-shaped loosening plow 22, and, in conjunction with the bucket-shaped loosening plow 9, forms a two-stage soil loosening process, effectively improving the soil loosening efficiency.

[0033] Among them, after the bucket-shaped loosening plow 9 descends, its bucket-shaped structure can penetrate deep into the soil, breaking up large clumps of compacted soil into smaller pieces, thereby improving the aeration and permeability of the deep soil. At the same time, the arc-shaped loosening plow 22, which descends synchronously with the vertical plate 19, can turn over the small clumps of soil with its arc-shaped blade, further loosening and flattening the deep soil broken up by the bucket-shaped loosening plow 9, reducing soil surface compaction, and adapting to the loosening needs of different soils.

[0034] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
