Description

Technical Field

[0001] The utility model belongs to the technical field of excavating and crushing soil, and in particular relates to a combined yam excavating and vibrating soil crushing device capable of realizing vibrating soil crushing. Background Art

[0002] The yam excavation and vibration crushing device is a mechanical device used during yam harvesting to break up the soil and separate the yams from the soil through vibration. It combines mechanical, hydraulic, and vibration technologies to improve yam harvesting efficiency, reduce labor intensity, and minimize yam damage during the harvesting process. The yam excavation and vibration crushing device not only quickly breaks up the soil and separates the yams from the soil, thereby improving yam harvesting efficiency and reducing the burden of manual excavation and soil separation, but also handles the yams more gently, reducing damage and breakage during the harvesting process. The yam excavation and vibration crushing device is primarily used in the mechanized harvesting process of yam cultivation.

[0003] During operation, the existing yam excavation and vibration crushing device mainly relies on a vibrating shovel to directly act on the middle soil mound containing the yam to achieve excavation. However, the excavated yams are often accompanied by a large amount of soil, which increases the burden of subsequent cleaning work. Secondly, the device fails to fully consider the effective support on both sides of the middle soil mound during the excavation process, resulting in the soil mound easily collapsing in the ditch during excavation, which in turn causes the yams to break. This not only damages the integrity of the yams, but also seriously affects their final harvest quality. In summary, while improving the excavation efficiency, the existing yam excavation and vibration crushing device fails to effectively solve the problem of yam damage caused by excessive soil on the yams and soil mound collapse, and thus has certain deficiencies in practicality and operating results.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Example 1:

[0029] See also Figure 1-4 The utility model provides a combined yam excavation and vibration soil crushing device capable of achieving vibration soil crushing, comprising:

[0030] Installation frame 1 and positioning frame 2;

[0031] Two crushing plates 3 are rotatably connected to both sides of the bottom end of the positioning frame 2, and the bottom ends of the two crushing plates 3 are provided with a same vibrating shovel 4;

[0032] The driving shaft 5 is rotatably connected to one side of the interior of the mounting frame 1. A limiting shaft 6 is rotatably provided in the mounting frame 1 at one end of the driving shaft 5. A positioning shaft 7 is rotatably connected to one side of the positioning frame 2.

[0033] The threaded rod 8 is rotatably connected to the bottom end of the mounting frame 1 . The external threads on both sides of the threaded rod 8 are arranged in opposite directions. Adjustment sleeves 9 are provided on both sides of the threaded rod 8 .

[0034] Specifically, such as Figure 1 As shown, both crushing plates 3 are arranged in a mesh structure, with multiple crushing teeth 10 provided on opposite sides of each crushing plate 3. These crushing teeth 10 are mounted on the two crushing plates 3 in a staggered, equidistant, and symmetrical arrangement. In one embodiment, the multiple crushing teeth 10 can be of varying lengths. Specifically, when designing the vibrating shovel 4, the use of multiple, parallel vibrating teeth can improve its efficiency and processing capacity. The arc-shaped vibrating teeth facilitate better contact with the surface of the material being processed, thereby more effectively transmitting the vibration force. The arc-shaped vibrating teeth can penetrate deeply into the material, promoting its loosening and movement, which is particularly advantageous when processing sticky or wet materials.

[0035] In one embodiment, the vibrating shovel 4 and the plurality of crushing teeth 10 can be designed with different lengths based on actual needs. This design allows the vibrating shovel to be more flexible and effective in handling materials of varying depths or hardness. For example, longer crushing teeth can penetrate deeper into harder or deeper layers of material, while shorter crushing teeth can handle surface or looser materials.

[0036] Furthermore, the staggered, equidistant, and symmetrical arrangement ensures uniform distribution of the crushing teeth 10 across the crushing plate 3, which helps achieve more uniform vibration force transmission and wider coverage. This arrangement also reduces interference between the teeth, thereby improving the overall performance and durability of the crushing plate. This design, with the crushing plates 3 on both sides, prevents soil from collapsing in the trench during excavation, potentially damaging the yams. The multiple crushing teeth 10 on opposite sides of the two crushing plates 3 assist in crushing the soil, improving the crushing efficiency and enabling a more thorough separation of the yams from the soil.

[0037] Specifically, such as Figure 1 As shown, both ends of the positioning shaft 7 pass through both sides of the positioning frame 2 respectively, and are both provided with eccentric wheels 11. One side of the two eccentric wheels 11 is rotatably connected to a vibration rod 12, and the other ends of the two vibration rods 12 are rotatably connected to both sides of the vibration shovel 4. When the positioning shaft 7 drives the two eccentric wheels 11 to rotate, it can drive the vibration shovel 4 to work through the two vibration rods 12 to break the middle soil and separate the soil and yam. In one embodiment, the vibration shovel 4 may include a plurality of parallel arranged vibration teeth, and the vibration teeth are arc-shaped to enhance its vibration effect during operation. The arc-shaped vibration teeth can better fit the surface of the processed material, thereby providing more effective vibration force transmission. This design helps to improve the working efficiency of the vibration shovel, especially when processing sticky or wet materials, the arc-shaped vibration teeth can penetrate the material more deeply, promoting the loosening and movement of the material.

[0038] In addition, the parallel arrangement of the vibrating teeth ensures a uniform distribution of the vibration force, which can reduce excessive wear on individual vibrating teeth and extend the service life of the vibrating shovel. In actual applications, this design of the vibrating shovel 4 can adapt to a variety of different working environments and material properties, and can provide a stable and efficient vibration loosening effect in various occasions. The design of the arc-shaped vibrating teeth also takes into account the convenience of maintenance and replacement. Since the vibrating teeth are arranged in parallel, they can be quickly disassembled and installed when worn vibrating teeth need to be replaced, reducing maintenance time and costs. In general, this design not only improves the working performance of the vibrating shovel, but also takes into account the convenience and economy in actual operation.

[0039] Specifically, such as Figure 1 、 Figure 2 and Figure 4As shown, sprockets are provided on the outside of the drive shaft 5, the limiting shaft 6, and the positioning shaft 7. The multiple sprockets are provided with a common transmission chain 13. Through the transmission chain 13, the drive shaft 5 can drive the limiting shaft 6 and the positioning shaft 7 to rotate synchronously. A drive motor 14 is provided on one side of the mounting frame 1. The drive motor 14 is conventional and will not be described in detail here. One end of the drive shaft 5 passes through one side of the mounting frame 1 and is arranged on the output end of the drive motor 14. In one embodiment, the transmission chain can be implemented by a roller chain transmission. Specifically, it can be composed of inner chain plates, outer chain plates, pins, sleeves, and rollers. Roller chains can provide good wear resistance and are suitable for a variety of industrial applications, including power transmission and material transportation. During design, the chain pitch, the number of teeth on the sprocket, and the material can be adjusted to adapt to different load and speed requirements. In another embodiment, it can be implemented by a toothed chain transmission. Specifically, the transmission can be achieved by engaging chain plates with specific tooth shapes with the sprockets. Compared to roller chains, toothed chains offer improved motion smoothness, lower noise, and higher permissible chain speeds, making them suitable for applications requiring high speeds or high precision. In another embodiment, a multi-row chain transmission can be employed. Specifically, when a single chain cannot meet the load requirements, the use of multiple rows of chains in parallel can be considered. Multiple rows of chains can significantly increase the load-bearing capacity of the transmission. Those skilled in the art may also employ any other suitable method to achieve transmission, and this invention is not intended to limit this.

[0040] Specifically, such as Figure 1 、 Figure 2 、 Figure 4 As shown, two mounting openings are provided on one side of the mounting frame 1, and corresponding adjustment plates 15 are provided in the two mounting openings. The two ends of the limit shaft 6 are respectively rotatably connected to one side of the two adjustment plates 15. The bottom ends of the two adjustment plates 15 are provided with limit springs 16, and the bottom ends of the two limit springs 16 are respectively arranged at the bottom ends of the two mounting openings. The two adjustment plates 15 that can slide in the mounting openings can move the position of the limit shaft 6. The limit springs 16 at the bottom ends of the two adjustment plates 15 can adjust the position of the limit shaft 6, thereby adjusting the tension of the transmission chain 13, so that when the positioning shaft 7 is at different positions, the driving shaft 5 can drive the positioning shaft 7 to rotate.

[0041] Specifically, such as Figure 2 As shown, a servo motor 17 is provided on one side of the mounting frame 1. The servo motor 17 is a prior art and will not be described in detail here. One end of the threaded rod 8 passes through the mounting frame 1 and is provided on the output end of the servo motor 17. The output end of the servo motor 17 can drive the threaded rod 8 to rotate.

[0042] See Figure 1-4When using the yam excavation vibration crushing device to excavate yam, it is first necessary to start the drive motor 14. The output end of the drive motor 14 will drive the drive shaft 5 to rotate. The drive shaft 5 will drive the limit shaft 6 and the positioning shaft 7 to rotate synchronously through the transmission chain 13. The positioning shaft 7 will drive the eccentric wheels 11 at both ends to rotate. The two eccentric wheels 11 will drive the bottom vibration shovel 4 to swing through the two vibration rods 12 to excavate the yam. During the excavation process, the soil crushing plates 3 on both sides can prevent the soil from collapsing in the ditch and causing damage to the yam. The multiple soil crushing teeth 10 on one side of the soil crushing plate 3 can assist in crushing the soil, so that the yam is completely separated from the soil, making the yam excavation vibration crushing device more practical.

[0043] Example 2:

[0044] See also Figure 1-4 The utility model provides a combined yam excavation and vibration soil crushing device capable of achieving vibration soil crushing, comprising:

[0050] Through its design, by rotating the threaded rod 8, the adjustment sleeves 9 on both sides can be driven to move in relative directions, and when the rotation stops, the position of the adjustment sleeve 9 can be locked. In conjunction with the two linkage plates 18, the position of the positioning frame 2 can be adjusted. The positioning frame 2 can adjust the position of the vibrating shovel 4 and the two crushing plates 3, so that it can dig yams at different depths.

[0051] Specifically, such as Figure 2 and Figure 3As shown, a limit rod 19 is provided at the bottom end of the mounting frame 1, and the two adjustment sleeves 9 are penetrated by a limit hole adapted to the limit rod 19. The limit rod 19 passes through the two limit holes and is slidably connected to the side wall of the limit hole.
