Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, and more specifically, to an agricultural soil loosening device suitable for mountainous areas. Background Technology

[0002] Soil improvement refers to a series of technical measures that utilize theories and techniques from multiple disciplines such as soil science, biology, and ecology to eliminate or prevent adverse factors that affect crop growth and cause soil degradation, improve soil properties, enhance soil fertility, and create favorable soil environmental conditions for crops. Loosening the soil is one such method of soil improvement. After being plowed, the soil has increased porosity, improved aeration, and allows water and air to penetrate the soil more effectively.

[0003] For example, a utility model patent with publication number CN220711978U discloses a plowing machine, including a shell assembly, a plowing assembly, and a crushing assembly. The plowing assembly is disposed on the inner wall of the shell assembly, and the crushing assembly is fixedly connected to the front end of the shell assembly.

The connecting shell has rotatably connected movable wheels on both the left and right ends and the front and rear sides. A controller is disposed on the rear side of the top of the connecting shell, and a handle is fixedly connected to the top of the rear end of the connecting shell. The plowing assembly includes a first motor, and a threaded rod is fixedly connected to the drive shaft of the first motor.

[0004] In the aforementioned patent, the inventor believes that when the soil loosening blades are used, the contact area with the soil is small and the cutting angle is not suitable, so the soil loosening efficiency needs to be improved. In addition, when the machine passes over the field ridges, there is a problem with poor crossing ability.

[0005] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide an agricultural soil loosening device suitable for mountainous areas, in order to achieve a more practical purpose. Summary of the Invention

[0006] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can address the low soil loosening efficiency and poor mobility of current agricultural soil loosening equipment.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an agricultural soil loosening device suitable for mountainous areas, comprising a frame, an axle at the rear of the frame, mountain wheels rotatably connected to both ends of the axle, a lifting assembly between the axle and the frame, a guide assembly between the axle and the frame, and a locking assembly on the lifting assembly;

[0026] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] See also Figures 1-5 This utility model provides an agricultural soil loosening device suitable for mountainous areas, including a frame 1, with an axle 2 at the rear of the frame 1, and mountain wheels 3 rotatably connected to both ends of the axle 2.

[0028] Axle 2 provides rotational support for mountain bike wheel 3, which can be used to support the frame 1 to move in mountainous fields.

[0029] In this embodiment: a lifting assembly is provided between the axle 2 and the frame 1. The lifting assembly includes a bracket 4, which is fixedly connected to the axle 2. A threaded rod 5 is rotatably connected to the inner side of the bracket 4. One end of the threaded rod 5 passes through the bracket 4 and is fixedly connected to a rotating frame 6. A threaded sleeve 7 is threadedly connected to the threaded rod 5 and is fixedly connected to the frame 1.

[0030] Both ends of the threaded rod 5 are rotatably connected to the bracket 4. By hand-cranking the rotating frame 6, the rotation of the rotating frame 6 can drive the threaded rod 5 to rotate. The threaded rod 5 is threadedly connected to the threaded sleeve 7 and can be moved by threaded feed. In this way, the threaded rod 5 can provide lifting capacity for the shaft 2 through the bracket 4. The threaded rod 5 can be raised up to 30 centimeters. In this way, the frame 1 and the mountain bike wheel 3 can be height adjusted to achieve the purpose of adjusting the height of the frame 1. The soil loosening equipment based on the frame 1 can be easily moved in the field and easily avoid moving obstacles. When it is necessary to use the soil loosening equipment on the frame 1 for operation, it can be lowered by controlling the lifting component.

[0031] In this embodiment, a guide assembly is also provided between the axle 2 and the frame 1. The guide assembly includes a guide rod 20, which is fixedly connected to the axle 2. A sleeve 21 is slidably connected to the guide rod 20, and the sleeve 21 is fixedly connected to the frame 1.

[0032] In this application, there are two sets of guide components. The threaded rod 5 is raised and lowered to pull the shaft rod 2. At this time, the guide rod 20 can slide inside the sleeve 21. The sleeve 21 limits the movement path of the guide rod 20, so that the shaft rod 2 can achieve stable raising and lowering in the vertical direction.

[0033] In this embodiment: a locking component is provided on the lifting assembly. The locking component includes a positioning disk 8, which is fixedly connected to the threaded rod 5. A positioning disk 9 is provided at the bottom of the positioning disk 8 and is fixedly connected to the top of the bracket 4. A fixing screw 10 is provided between the positioning disk 8 and the positioning disk 9. The positioning disk 8 is provided with multiple through holes for the fixing screw 10 to pass through, and the positioning disk 9 is provided with multiple fixing holes for the threaded connection of the fixing screw 10.

[0034] Since the rotation of the threaded rod 5 is achieved by hand-cranking the rotating frame 6, this drive setting can reduce drive costs and meet practicality. In order to prevent the threaded rod 5 from affecting the height of the frame 1 and the mountain bike wheel 3 due to unplanned rotation, a fixing screw 10 is used to pass through one of the holes on the positioning plate 8. One end of the fixing screw 10 can be threaded to one of the fixing holes on the positioning plate 9. When the positioning plate 8 and the positioning plate 9 are locked, the threaded rod 5 can be locked on the bracket 4. In this way, the entire lifting assembly will not move, so as to ensure high stability of the height drive. Similarly, when the lifting assembly needs to adjust the working height, the fixing screw 10 can be released first.

[0035] In this embodiment: A second axle 11 is fixedly connected to the inner side of the frame 1. A hub motor 12 is installed on the second axle 11. A brake 15 for braking the hub motor 12 is also installed on the second axle 11. A tail support 16 is fixedly connected to the rear of the frame 1. A dividing plate 161 is fixedly connected to the top of the tail support 16. A handlebar bracket 17 is rotatably connected to the dividing plate 161. A pull ring dividing pin 171 is provided between the handlebar bracket 17 and the dividing plate 161. A Hall handle 22 is provided at one end of the handlebar bracket 17. A handbrake 23 is provided at the other end of the handlebar bracket 17.

[0036] The tail support 16 allows the entire agricultural soil loosening device suitable for mountainous terrain to make contact with the ground. The brake 15 is a drum brake, which can be used in conjunction with a handbrake with a steel cable for braking control. Since the hub motor 12 is rotatably connected to the axle 11, the handbrake 23 position allows for convenient control of the hub motor 12's rotation and stop via the brake 15. By controlling the hub motor's speed or stopping it in an emergency through the brake, the loosening speed can be adjusted instantly in complex terrain, preventing slippage or overload.

[0037] The indexing plate 161 has a semi-circular structure. The handle 17 is rotatably connected to the indexing plate 161 via a pivot. The indexing plate 161 has multiple mounting holes for fixing the pull ring indexing pin 171. When the pull ring indexing pin 171 is released, the handle 17 can rotate at the connection point of the indexing plate 161. Then, the pull ring indexing pin 171 is threaded through the handle 17 and the indexing plate 161 in sequence to fix the handle 17, so as to adjust the tilt of the handle 17. In this way, the end of the handle 17 near the handbrake 23 or Hall handle 22 can be easily adjusted in height to accommodate operators of different heights.

[0038] The brake 15, hub motor 12, Hall handle 22 and handbrake 23 in this application are all existing mature structures, and their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0039] In this embodiment: a plurality of soil-breaking blades 13 are provided on the hub motor 12, and a mounting bracket 14 is bolted to the hub of the hub motor 12. The soil-breaking blades 13 are fixedly connected to the mounting bracket 14 and are inclined.

[0040] The mounting bracket 14 is bolted to the hub motor 12, which facilitates the assembly of the soil-breaking blade 13 on the hub motor 12. In this application, the cutting angle of the soil-breaking blade 13 is between 21 and 30 degrees, and its length is between 45 and 60 centimeters. When the hub motor 12 rotates and drives multiple soil-breaking blades 13 to extend into the soil, the soil-breaking blades 13 can increase the contact area with the soil and better extend into the soil, thus improving the soil-loosening effect and efficiency.

[0041] It is worth noting that, in order to facilitate the movement of the soil-breaking facility consisting of the hub motor 12 and the soil-breaking blade 13 in the field, the height of the vehicle frame 1 can be adjusted by using the lifting assembly.

[0042] In this embodiment, a plow blade 19 is provided at the bottom of the tail support 16.

[0043] The plow blade 19 can be bolted to the tail support 16. After the soil breaking blade 13 breaks the ground, the plow blade 19 can plow and turn the soil on the broken ground, forming a layered loosening effect with the soil breaking blade, and improving soil permeability.

[0044] In this embodiment, a battery 18 is provided on the top of the tail support 16. Its center of gravity is positioned at the rear to balance the soil loosening resistance at the front, and it is also convenient for charging or replacement.

[0045] The rear support 16 is equipped with a battery frame for limiting the storage battery 18. The battery frame can stably support the storage battery. Using existing wiring technology, the Hall handle 22 can be electrically connected to the hub motor 12 via the storage battery 18, which can conveniently provide drive power to the hub motor 12.
