Description

Technical Field

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

[0002] A subsoiler is a type of tillage machinery used in conjunction with a high-horsepower tractor. It is mainly used for mechanized tillage of deep soil between rows or in all directions, in order to carry out sowing. To expand its functions, some subsoilers will have accessory connecting structures installed on the frame, such as bolted brackets or welded supports, to carry auxiliary components such as fertilizer and pesticide spraying equipment, so as to achieve combined operations.

[0003] However, in existing technologies, the adjustment of deep tillage depth in conventional subsoilers often relies on hydraulic suspension systems or mechanical adjustments by operators. Hydraulic systems suffer from slow response speed and low adjustment accuracy, making it difficult to accurately control the depth in real time according to soil texture. Adjustment requires stopping the machine, which is inefficient. When the soil texture is uneven or the plot is undulating, traditional adjustment methods can easily lead to inconsistent deep tillage depths, affecting the quality of cultivation. Furthermore, the transmission mechanism lacks buffer protection when encountering resistance, causing wear or damage to components. Therefore, a subsoiler for agricultural planting and sowing is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a deep tillage machine for agricultural planting and sowing, which aims to improve the problem of inconsistent deep tillage depth caused by the adjustment method in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-4 This utility model provides an embodiment of a deep tillage machine for agricultural planting and sowing, comprising a frame 1, a mounting plate 3 fixedly connected to the top of the frame 1, and a lifting mechanism installed in the middle of the mounting plate 3, which enables precise depth control and adaptive adjustment of the deep tillage shovel 17. A mounting block 19 is mounted on the outer side of the frame 1 via a snap-fit ​​assembly, and a housing 4 is fixedly connected to the inner side of the mounting plate 3; the snap-fit ​​assembly facilitates the quick replacement of the atomizing nozzle 30.

[0035] The lifting mechanism includes a drive assembly, a fixing assembly, and a connecting assembly. The drive assembly includes a drive motor 6, which is fixedly connected to the outside of the outer casing 4. A worm gear 7 is fixedly connected to the output end of the drive motor 6. A connecting rod 11 is rotatably connected to the middle of the outer casing 4. A worm wheel 10 is fixedly connected to the outside of the connecting rod 11. The worm gear 7 and the worm wheel 10 mesh, ensuring stability during the lifting and lowering of the deep loosening shovel 17 through the transmission of the worm gear 7 and the worm wheel 10. A fixing block 15 is fixedly connected to the outside of the mounting plate 3, and a gear 9 is fixedly connected to the outside of the connecting rod 11. As the connecting rod 11 rotates within the outer casing 4, the gear 9 fixed to the connecting rod 11 rotates synchronously. A rack 8 is slidably connected to the inside of the outer casing 4, and the gear 9 meshes with the rack 8. The rotational motion of the gear 9 is converted into the linear reciprocating motion of the rack 8, pushing the rack 8 to move up and down vertically, providing direct power for the lifting and lowering of the deep loosening shovel 17.

[0036] The fixing assembly includes a protective shell 5, which is fixedly connected to the outside of the outer shell 4. The inner side of the protective shell 5 is fixedly connected to the outside of the drive motor 6. A fixing block 12 is fixedly connected to the bottom of the rack 8. The fixing block 12 is used to connect the connecting plate 13 and transmit the linear motion of the rack 8 to the deep loosening shovel 17 to ensure the synchronization of the lifting action.

[0037] The connecting assembly includes a connecting plate 13, which is fixedly connected to the outside of the fixing block 12 and connected to the rack 8 via the fixing block 12. The connecting plate 13 receives the lifting power of the rack 8 and also serves as the mounting carrier for the subsoil shovel 17, ensuring that the subsoil shovel 17 moves synchronously with the connecting plate 13. A telescopic rod 16 is fixedly connected to the bottom of the fixing block 15. The telescopic rod 16 provides support and guidance when the connecting plate 13 is raised or lowered, and also buffers the vibration of the subsoil shovel 17 during operation through its telescopic characteristics. A connecting block 14 is fixedly connected to the bottom of the telescopic rod 16 and is fixedly connected to the top of the connecting plate 13. The subsoil shovel 17 is installed in the middle of the connecting plate 13. The subsoil shovel 17 adjusts its soil penetration depth through a lifting mechanism to achieve deep loosening operations on soils of different textures, meeting the soil loosening requirements in agricultural planting.

[0038] Reference Figure 5 and Figure 6 The snap-fit ​​assembly includes mounting block 22, which is fixedly connected to the outside of frame 1. A housing 23 is fixedly connected to the middle of mounting block 22, and a pull rod 25 is slidably connected to the middle of housing 23. A spring 26 is sleeved on the outside of pull rod 25, and a retaining ring 27 is fixedly connected to the outside of pull rod 25. The snap-fit ​​assembly also includes a pull ring 24, which is fixedly connected to the end of pull rod 25. When it is necessary to replace the atomizing nozzle 30, first pull the pull ring 24 to move pull rod 25 outward, causing pull rod 25 to disengage from slot 21. Then, disengage slot 20 in mounting block 19 from the retaining strip 18, thus completing the replacement and removal of the atomizing nozzle 30.

[0039] Mounting block 19 has a slot 21 in the middle, and the pull rod 25 is engaged with slot 21. Mounting block 19 also has a slot 20 in the middle. A retaining strip 18 is fixedly connected to the outside of the frame 1, and the retaining strip 18 is engaged with slot 20. Align slot 20 with retaining strip 18 and push it in to complete the engagement.

[0040] Reference Figure 1 and Figure 2 A water tank 28 is fixedly connected to the top of frame 1. The water tank 28 is used to hold irrigation water, pesticides, or fertilizer solutions, providing a liquid medium for soil treatment during deep tillage or subsequent sowing. One end of a hose 29 is fixedly connected to the middle of the water tank 28, and the end of the hose 29 away from the water tank 28 is fixedly connected to the middle of mounting block 19. The hose 29 allows the liquid in the water tank 28 to be delivered to the atomizing nozzle 30. The atomizing nozzle 30 is fixedly connected to the bottom of mounting block 19. The atomizing nozzle 30 sprays liquid simultaneously during deep tillage, softening the soil. Multiple wheels 2 are fixedly connected to the bottom of frame 1.

[0041] Working principle: When the subsoiler is used for planting, the drive motor 6 is first started and rotated to drive the worm 7 to rotate. Due to the meshing of the worm 7 and the worm wheel 10, the high speed is converted into a low speed and a large torque. The worm wheel 10 is fixed on the connecting rod 11, which drives the connecting rod 11 to rotate synchronously. This causes the gear 9 and the rack 8 outside the connecting rod 11 to mesh. The rotation of the gear 9 pushes the rack 8 to make a vertical linear motion, which in turn drives the fixed block 12 and the connecting plate 13 to move up and down together, and synchronously drives the subsoil shovel 17 to rise and fall.

[0042] When installing the atomizing nozzle 30, align the slot 20 of the mounting block 19 with the retaining strip 18 of the frame 1, and push it in until the slot 20 and retaining strip 18 are fully engaged. Under the pushing force of the spring 26, the pull rod 25 is inserted into the slot 21 of the mounting block 19. The retaining ring 27 restricts the displacement of the pull rod 25, so that the mounting block 19 is tightly fixed to the frame 1. Pulling the pull ring 24 causes the pull rod 25 to compress the spring 26, so that the pull rod 25 is disengaged from the slot 21. When it is necessary to replace the atomizing nozzle 30 with a different specification, pull the pull ring 24 to move the pull rod 25 outward, so that the pull rod 25 is disengaged from the slot 21. Then lift the mounting block 19 upward to separate the slot 20 from the retaining strip 18, so that the mounting block 19 and the atomizing nozzle 30 can be removed.

[0043] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
