Description

Technical Field

[0001] This utility model relates to the field of deep tillage machine technology, and in particular to a deep tillage machine for agricultural planting and sowing. Background Technology

[0002] In modern agricultural production, soil cultivation and improvement are crucial for ensuring high and stable crop yields. Prolonged shallow tillage can lead to the formation of a hard, compacted plow pan, which severely hinders root development, water penetration, and nutrient absorption. Subsoilers, as important agricultural machinery, primarily function to loosen the soil, break up the plow pan, improve its physical structure, increase its water retention and permeability, and create a favorable environment for crop roots. Therefore, high-performance subsoilers play a vital role in agricultural production.

[0003] Existing subsoilers typically consist of a suspension system for connecting to a tractor, a frame to support the working components, and a subsoil shovel for loosening the soil. The frame is often designed as a modular structure composed of multiple brackets to accommodate different working widths or for ease of transport and storage. During assembly, these brackets are generally connected and secured using bolts and nuts. Operators need to align the connecting holes of the different brackets, insert the bolts, and use wrenches or other specialized tools to tighten the nuts, thus achieving a rigid connection of the entire frame.

[0004] However, the existing technology of using bolts to fix and connect brackets has significant shortcomings in practical applications. First, this connection process requires tools such as wrenches, and tightening the bolts one by one when assembling multiple brackets is cumbersome, time-consuming, and labor-intensive. Second, in field operations, tools or loose parts such as bolts and nuts are easily lost, causing inconvenience for rapid on-site assembly and debugging. Therefore, this connection method not only reduces the preparation efficiency of the subsoiler before operation but also affects the overall ease of use of the equipment, and urgently needs improvement. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a deep tillage machine for agricultural planting and sowing, which aims to improve the problem that traditional brackets need to be connected and assembled with bolts and tools, which is inconvenient.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a deep tillage machine for agricultural planting and sowing, including a seeder, a deep tillage machine fixedly connected to one side of the seeder, a bracket fixedly connected to one side of the deep tillage machine, and a connecting component provided inside the bracket; The connecting assembly includes a connecting pin, which is slidably connected inside the bracket. A limiting rod is fixedly connected inside the connecting pin. A symmetrically arranged locking block is slidably connected to the outer wall of the limiting rod.

A disassembly assembly is provided inside the connecting pin.

[0007] As a further description of the above technical solution: The disassembly assembly includes a connecting rod that is slidably connected inside a connecting pin. One end of the connecting rod is fixedly connected to a disassembly ring, which is slidably connected to the outer wall of the connecting pin. A reset assembly is provided on one side of the connecting rod.

[0008] As a further description of the above technical solution: The reset assembly includes a connecting block, one side of which is fixedly connected to one side of a connecting rod. A second limiting rod is slidably connected inside the connecting block. One end of the second limiting rod is fixedly connected inside a connecting pin. A second spring is sleeved on the outer wall of the second limiting rod. One end of the second spring is fixedly connected to one side of the connecting block, and the other end of the second spring is fixedly connected inside the connecting pin.

[0009] As a further description of the above technical solution: A deep loosening shovel is fixedly connected to the bottom of the bracket, and an adjustment block is fixedly connected to one side of the deep loosening shovel.

[0010] As a further description of the above technical solution: The adjusting block has a threaded hole inside, and an adjusting plate is provided on the top of the adjusting block.

[0011] As a further description of the above technical solution: The adjusting plate has an adjusting groove inside, and fastening bolts are installed inside the adjusting plate.

[0012] As a further description of the above technical solution: The fastening bolt is threaded into the threaded hole, and a wing-shaped deep loosening shovel is fixedly connected to one side of the adjusting plate.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the connecting pin is first inserted directly into the bracket, and then the locking block inside the bracket unfolds to lock onto the outer wall of the bracket, preventing the connecting pin from coming off the bracket. The locking block is supported by the tension of the first spring, so that the locking block will not retract into the connecting pin at will, thus achieving the effect of facilitating the connection and assembly of the bracket. This solves the problem that traditional brackets need to be connected and assembled with bolts and tools, which is inconvenient, and improves the convenience of the deep tillage machine.

[0014] 2. In this utility model, after loosening the fastening bolts, the position of the adjusting plate on the adjusting block is adjusted. The adjusting plate is adjusted through the adjusting groove. After it is in place, the fastening bolts are tightened again to fix it. This achieves the effect of easy adjustment of the deep tillage shovel, solves the problem that the length of the deep tillage shovel in traditional deep tillage machines is relatively fixed and cannot be adjusted according to different seeds and soils, and improves the practicality of the deep tillage machine.

The connecting assembly includes a connecting pin 4 as the connecting body. The connecting pin 4 is movably connected to the inside of the bracket 3 through a sliding fit, facilitating insertion and removal. A limiting rod 5, which provides a sliding track for the locking block 6, is fixedly connected inside the connecting pin 4. The outer wall of the limiting rod 5 is slidably connected to symmetrically arranged locking blocks 6, which are used to lock onto the outer wall of adjacent brackets 3. A first spring 7, which provides outward expansion elasticity to the locking block 6, is sleeved on the outer wall of the limiting rod 5. The two ends of the first spring 7 are fixedly connected to the two locking blocks 6 respectively to maintain the default unfolded state of the locking blocks 6. A disassembly assembly is provided inside the connecting pin 4 to control the retraction of the locking blocks 6 to unlock them. The disassembly assembly includes a connecting rod 9 for transmitting tension. The connecting rod 9 is slidably connected inside the connecting pin 4, with one end of the connecting rod 9... A disassembly ring 10 is fixedly connected to facilitate user operation by pulling. The disassembly ring 10 is slidably connected to the outer wall of the connecting pin 4. A reset component is provided on one side of the connecting rod 9 to automatically reset the disassembly assembly. The reset component includes a connecting block 12 as a force transmission and guiding component. One side of the connecting block 12 is fixedly connected to one side of the connecting rod 9. A limiting rod 8 is slidably connected inside the connecting block 12 to provide sliding guidance for the connecting block 12. One end of the limiting rod 8 is fixedly connected to the inside of the connecting pin 4. A second spring 11 is sleeved on the outer wall of the limiting rod 8 to push the connecting block 12 to reset after the pulling force disappears. One end of the second spring 11 is fixedly connected to one side of the connecting block 12, and the other end of the second spring 11 is fixedly connected to the inside of the connecting pin 4, thereby ensuring that the disassembly assembly can automatically return to the initial position after operation.

[0019] Reference Figure 4 and Figure 5 The bracket 3 has a deep loosening shovel 13 fixedly connected to its bottom, which provides a stable mounting base for the wing-shaped deep loosening shovel 19 and its adjustment mechanism. An adjusting block 14 is fixedly connected to one side of the deep loosening shovel 13, serving as a fixed base for the adjustment mechanism and providing a fixing point for the fastening bolt 16. The adjusting block 14 has a threaded hole 15 inside, providing a threaded fit for the fastening bolt 16 to generate locking force. An adjusting plate 17 is provided on the top of the adjusting block 14, serving as a direct carrier for the wing-shaped deep loosening shovel 19 and adjusting the deep loosening effect by changing its position. The adjusting plate 17 has an adjusting groove 18 inside, providing a moving channel for the fastening bolt 16, thereby achieving position adjustment of the adjusting plate 17. The adjusting plate 17 has a fastening bolt 16 inside, which acts as a locking element to fix the adjusting plate 17 in the desired position. The fastening bolt 16 is threaded into the threaded hole 15, and its function is to reliably fix the adjusting plate 17 onto the adjusting block 14 by tightening. A wing-shaped deep loosening shovel 19 is fixedly connected to one side of the adjusting plate 17, and its function is to serve as the final working component to directly loosen the soil.

[0020] Working principle: When using this agricultural deep tillage machine for planting, when first assembling the bracket 3, simply insert the connecting pin 4 directly into the bracket 3. Then, the locking block 6 inside the bracket 3 unfolds and locks onto the outer wall of the bracket 3, preventing the connecting pin 4 from coming off the bracket 3. The locking block 6 is supported by the tension of the first spring 7, so that the locking block 6 will not retract into the connecting pin 4 at will. When disassembly is required, simply pull one end of the connecting rod 9 out of the connecting pin 4, so that the connecting rod 9 drives the locking block 6 to retract into the connecting pin 4 through the disassembly ring 10, thereby pulling the connecting pin 4 out of the bracket 3. After releasing the connecting rod 9, the disassembly ring 10 is reset by the tension of the second spring 11, thereby releasing the locking block 6, achieving the effect of facilitating the connection and assembly of the bracket 3. When it is necessary to adjust the depth of the wing-shaped deep tillage shovel 19 inserted into the soil, first loosen the fastening bolt 16 and then adjust the position of the adjusting plate 17 on the adjusting block 14. The adjusting plate 17 is adjusted through the adjusting groove 18. After it is in place, tighten the fastening bolt 16 again to fix it, thereby fixing the wing-shaped deep tillage shovel 19. This achieves the effect of facilitating the adjustment of the deep tillage shovel. Subsequently, the deep tillage machine 2 can plow the land and simultaneously sow seeds through the seeder 1, achieving the effect of facilitating the adjustment of the deep tillage shovel.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
