Description

Technical Field

[0001] This utility model relates to the field of konjac planting technology, specifically to a rotary tillage digging device for konjac planting. Background Technology

[0002] Konjac is a high-value-added economic crop widely used in the food, pharmaceutical, and industrial sectors. Digging holes is a crucial step in its cultivation, directly impacting tuber growth and yield. With the development of agricultural mechanization, specialized hole-digging equipment, such as small hole diggers, has become increasingly common.

[0003] Utility model patent with authorization announcement number CN202321984375.7 discloses an unmanned hole-digging planting machine for konjac cultivation. The unmanned hole-digging planting machine for konjac cultivation includes a planting vehicle body and automatic moving wheels. The top surface of the planting vehicle body is provided with a support sleeve. The support sleeve is provided with a load-bearing hydraulic cylinder. The movable end of the load-bearing hydraulic cylinder is connected to a U-shaped connecting frame. The bottom end of the U-shaped connecting frame is provided with a drill bit control seat. The bottom end of the drill bit control seat is connected to a hole-digging drill bit. The side of the planting vehicle body away from the hole-digging drill bit is provided with a soil-dispensing arc plate. The top side of the soil-dispensing arc plate is provided with a drive motor, and the output shaft of the drive motor is connected to the top of the soil-dispensing arc plate. The planting vehicle uses a hydraulic cylinder and a U-shaped connecting frame to connect a digging drill bit to the main body of the planting vehicle for bottom digging. When the side of the planting vehicle moves to the top of the digging position, the konjac seeds are planted. After planting, as the planting vehicle continues to move, the soil on the side of the digging hole is moved and filled by the soil-moving arc plate. This realizes an integrated structure of automatic digging, planting and burying of soil for konjac planting, which does not require manual operation and improves the efficiency of konjac digging and planting.

[0004] Although the unmanned hole-digging planter for konjac planting has the advantage of automatic hole digging, the device still has the following problems in actual use: the device is only equipped with a single hole-digging drill bit. Due to the limitations of a single drill bit, the number of holes dug per unit time is limited, which is difficult to meet the needs of large-scale planting, thus prolonging the overall operation time and affecting the efficiency of konjac planting. In view of this, we propose a rotary tillage hole-digging device for konjac planting. Utility Model Content

The hole-digging assembly 2 includes a mounting frame 20, and the hinge seat 15 is fixedly connected to the top of the mounting frame 20. 5 is fixedly connected to the top of the mounting bracket 20 by bolts. Two guide rods 28 are fixed near both sides of the top of the mounting bracket 20. The guide rods 28 pass through the horizontal seat 1 and are slidably connected to the horizontal seat 1. A bidirectional threaded screw 21 is rotatably installed in the bottom opening of the mounting bracket 20. Both ends of the bidirectional threaded screw 21 are threadedly connected to the connecting seat 23. The outer wall of the connecting seat 23 has a groove 230. A second motor 24 is installed in the groove 230. A rotating shaft 26 is coaxially keyed to the output shaft of the second motor 24. A auger 27 for digging holes is coaxially keyed to the bottom end of the rotating shaft 26.

[0032] In this embodiment, a guide rod 22 is also fixedly connected to the bottom opening of the mounting bracket 20 by bolts. The guide rod 22 passes through the connecting seat 23 and is slidably connected to the connecting seat 23. The guide rod 22 guides the horizontal movement of the connecting seat 23, ensuring the stability and smoothness of the horizontal movement of the connecting seat 23.

[0033] In this embodiment, a support frame 25 is fixed to the bottom of the connecting seat 23, and the rotating shaft 26 passes through the support frame 25 and is rotatably connected to the support frame 25. The support frame 25 is fixed to the bottom of the connecting seat 23, providing stable support for the rotating shaft 26 and ensuring the stability of the screw 27 when rotating at high speed.

[0034] In this embodiment, the bottom of the cross seat 1 is bolted to support legs 17 on both the front and rear sides. A tie rod 19 is fixed between two adjacent support legs 17. Two wheels 18 are rotatably mounted on the bottom of each support leg 17. The design of the support legs 17 and wheels 18 enhances the mobility and stability of the equipment, and the tie rod 19 further reinforces the support leg structure to prevent the equipment from tilting. The rotatable design of the wheels 18 facilitates flexible movement of the equipment in complex terrain, improving work efficiency.

[0035] In this embodiment, the crank 13 has a Z-shaped cross-section, and the end of the crank 13 is rotatably connected to the inner wall of the housing 11 via a bearing. The Z-shaped cross-section design of the crank 13 enhances its rigidity and facilitates the reciprocating motion of the guide rod 22, while the bearing ensures the stability of the crank 13 and extends the service life of the equipment.

[0036] In this embodiment, one end of the bidirectional threaded screw 21 passes through the outer wall of the mounting bracket 20, and a handwheel 210 is coaxially keyed to the end of the bidirectional threaded screw 21. The handwheel 210 facilitates the rotation of the bidirectional threaded screw 21, improving the convenience and efficiency of operation.

[0037] In this embodiment, a push handle 16 is fixed at the rear end of the horizontal base 1. The cross-sectional shape of the push handle 16 is U-shaped. The U-shaped cross-section design of the push handle 16 is ergonomic and facilitates user operation and movement of mobile devices.

[0038] In this embodiment, the mounting bracket 20 has a U-shaped cross-section and is made of stainless steel. The stainless steel material provides high strength and corrosion resistance, making it suitable for complex operating environments. Furthermore, the U-shaped cross-section design of the mounting bracket 20 enhances structural stability.

[0039] It should be added that in this embodiment, the crank 13 drives the connecting rod 14 to move, and the connecting rod 14 drives the mounting frame to move up and down reciprocally. This design allows the screw to perform a back-and-forth motion while rotating to dig the hole. This reciprocating motion causes the screw to continuously impact the soil during the digging process, further enhancing the soil breaking effect. This design is particularly suitable for treating compacted or stony soil, ensuring that the bottom of the hole is flat and of uniform depth, providing a better growing environment for konjac cultivation.

[0040] It is worth noting that the first motor 12 and the second motor 24 involved in this embodiment are existing conventional technologies, and will not be described in detail here.

[0041] Before use, the user first turns the handwheel 210, which drives the bidirectional threaded screw 21 to rotate. At this time, the connecting seats 23 on both sides move synchronously relative to each other. The connecting seats 23 synchronously drive the rotating shaft 26 and the screw 27 to move horizontally. When the two screws 27 move to the required distance, the user stops turning the handwheel 210.

[0042] In practical use, the user first connects the power supply to the second motor 24, and the second motor 24 starts working. The output shaft of the second motor 24 rotates, driving the rotating shaft 26 and the screw 27 to rotate. Then, the user connects the power supply to the first motor 12, and the first motor 12 starts working. The output shaft of the first motor 12 rotates, driving the crank 13 to rotate. The crank drives the connecting rod 14 to move, and the connecting rod 14 simultaneously drives the mounting frame 20 to move in the vertical direction. The mounting frame 20 then drives the rotating shaft 26 and the screw 27 to rise and fall. When the rotating screw 27 contacts the soil, the screw 27 can dig a deep pit.

[0043] Example 2

[0044] Please see Figure 6 As shown, this embodiment provides the following technical solution based on embodiment 1: a protective cover 110 is installed on the front end face of the housing 11 outside the first motor 12, and the bottom of the protective cover 110 is open.

[0045] Understandably, the protective cover 110 is installed on the outside of the first motor 12 to prevent dust and debris from entering and extend the motor's service life. Its bottom opening design facilitates heat dissipation, ensuring the stability and reliability of the motor during long-term operation.

[0046] Example 3

[0047] Please see Figure 7 As shown, this embodiment provides the following technical solution based on embodiment 1: A battery box 3 for installing batteries is fixedly connected to the top front side of the horizontal seat 1 by bolts. The battery box 3 is open at the top, and a cover plate 30 is fixedly connected to the top of the battery box 3 by bolts.

[0048] Understandably, the battery box 3 is fixed to the top of the cross seat 1 with bolts. It adopts a modular design, which facilitates quick installation and replacement of batteries. At the same time, the installed batteries can provide a continuous and stable power supply for the operation of the first motor 12 and the second motor 24.

[0049] In this embodiment, multiple heat dissipation slots 31 are provided on the upper part of both the front and rear walls of the battery box 3, and multiple wiring holes 32 are provided on the lower part of the front face of the battery box 3. The multiple heat dissipation slots 31 on the upper part of the front and rear walls of the battery box 3 effectively improve the heat dissipation efficiency of the battery by combining natural convection and forced air cooling, ensuring that the battery can maintain a stable operating temperature in high-temperature environments, extending the battery life, and reducing the safety hazards caused by overheating. The multiple wiring holes 32 facilitate the orderly arrangement of power cords and other cables.
