Description

Technical Field

[0001] This utility model relates to the technical field of tobacco planting equipment, specifically to a tobacco planting hole digging machine. Background Technology

[0002] In tobacco cultivation, planting holes need to be dug before transplanting. Traditional hole-digging mainly relies on manual labor using tools such as hoes and shovels, which is labor-intensive, inefficient, and results in holes of varying depths and spacing, affecting the quality of subsequent transplanting and the uniformity of tobacco growth.

[0003] Currently, while some general-purpose agricultural hole-digging equipment exists, most are designed for digging larger holes for fruit trees and forest trees. These devices are bulky, power-consuming, and unsuitable for the precise and efficient operation of digging small to medium-sized holes in tobacco fields. Furthermore, existing small-scale hole-digging equipment often lacks effective depth control mechanisms, making it difficult to ensure that the depth of each hole meets agronomic requirements. Additionally, the ease of operation and stability need improvement.

[0004] Therefore, there is an urgent need for a specialized hole-digging machine that is compact in structure, easy to operate, can accurately control the hole depth, and is particularly suitable for tobacco transplanting. Utility Model Content

[0005] This utility model provides a tobacco planting hole-digging machine, which is specifically designed for the agronomic requirements of tobacco planting and features a reasonable structure, convenient operation, controllable hole depth, and high work efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A tobacco planting hole-digging machine, comprising:

[0008] A frame, on which a power unit and two mirror-symmetrical rollers are provided, the power unit being used to drive the rollers to rotate, and a handrail is also provided on the frame;

[0009] A hole-digging mechanism includes a support base, a drive assembly, and at least one drill rod. The drill rod is rotatably mounted on the support base. The drive assembly is mounted on the support base and is used to drive the drill rod to rotate. A drill bit is fixedly connected to the lower end of the drill rod, and helical blades are provided on the drill rod.

[0010] A guiding depth limiting mechanism includes a rotary motor and a connecting frame. The connecting frame is movable up and down on the frame, and the rotary motor is mounted on the connecting frame. The support base is connected to the main shaft of the rotary motor.

[0011] Furthermore, the frame is provided with a first support and a second support. The first support is rotatably equipped with a first lead screw, and the second support is rotatably equipped with a second lead screw. The connecting seat is provided with two guide blocks, which are respectively fitted onto the first lead screw and the second lead screw. The ends of the first lead screw and the second lead screw are connected to a drive motor.

[0012] Furthermore, four drill rods are provided, including a first drill rod, a second drill rod, a third drill rod, and a fourth drill rod. The first and fourth drill rods are equipped with drive gears, and the second and third drill rods are equipped with driven gears. The drive gear of the first drill rod meshes with the driven gear of the second drill rod, and the drive gear of the fourth drill rod meshes with the driven gear of the third drill rod. The first drill rod is connected to a drive motor, and the second drill rod is connected to a drive motor.

[0013] Furthermore, the pitch of the helical blade gradually decreases from top to bottom.

[0014] Furthermore, the drill bit is a tapered drill bit with a tip angle of 30°-60°.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0016] In actual operation, the power unit drives the rollers to rotate, which in turn moves the frame to the location where the hole needs to be dug. Then, the connecting frame moves downward, which in turn moves the drill bit downward. At the same time, the drill rod rotates, thus realizing the hole-digging process. The rotary motor can drive the support base to rotate, thereby enabling hole digging in some special locations. The vertical movement of the connecting frame can control the depth of the hole digging. Attached Figure Description

Detailed Implementation

[0021] The present invention will now be described in detail with reference to the accompanying drawings.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0023] This embodiment provides a tobacco planting hole-digging machine, such as... Figures 1-2 As shown, it includes:

[0024] A frame 1 is provided with a power component and two mirror-symmetrical rollers 2. The power component is used to drive the rollers 2 to rotate. A handrail 3 is also provided on the frame.

[0025] A hole-digging mechanism includes a support base 4, a drive assembly, and at least one drill rod 5. The drill rod 5 is rotatably mounted on the support base 4. The drive assembly is mounted on the support base 4 and is used to drive the drill rod to rotate. A drill bit is fixedly connected to the lower end of the drill rod, and a helical blade 5 is provided on the drill rod.

[0026] The guide depth limiting mechanism includes a rotary motor 6 and a connecting frame 7. The connecting frame 7 is movable up and down on the frame 1. The rotary motor 6 is mounted on the connecting frame 7. The support base 4 is connected to the main shaft of the rotary motor 6.

[0027] In actual operation, the power unit drives the roller 2 to rotate, which in turn moves the frame 1 to the location where the hole needs to be dug. Then, the connecting frame 7 moves downward, which in turn moves the drill bit downward. At the same time, the drill rod rotates, thus realizing the hole-digging process. The rotary motor 6 can drive the support base 4 to rotate, enabling hole digging in specific locations. The vertical movement of the connecting frame 7 controls the depth of the hole. Compared with manual hole digging, this invention improves work efficiency and saves time and effort.

[0028] To further optimize the above embodiment, in order to enable the connecting frame 7 to move vertically on the frame, the frame 1 is provided with a first support 8 and a second support 9. The first support 8 is rotatably equipped with a first lead screw 10, and the second support 9 is rotatably equipped with a second lead screw 11. The connecting seat 4 is provided with two guide blocks 12, which are respectively fitted onto the first lead screw 10 and the second lead screw 11. The ends of the first lead screw 10 and the second lead screw 11 are connected to a drive motor. The drive motor drives the first lead screw 10 and the second lead screw 11 to rotate, thereby causing the guide blocks 12 to move along the axial direction of the lead screw, thus enabling the connecting frame 7 to move vertically.

[0029] In a further optimization of the above embodiment, four drill rods are provided, including a first drill rod 13, a second drill rod 14, a third drill rod 15, and a fourth drill rod 16. The first drill rod 13 and the fourth drill rod 16 are provided with drive gears 17, and the second drill rod 14 and the third drill rod 15 are provided with driven gears 18. The drive gear 17 of the first drill rod 13 is meshed with the driven gear 18 of the second drill rod 14, and the drive gear 17 of the fourth drill rod 16 is meshed with the driven gear 18 of the third drill rod 15.

[0030] In a further optimization of the above embodiment, the pitch of the helical blade 5 gradually decreases from top to bottom. This design facilitates the smooth upward transport and distribution of drilled soil around the pit, preventing soil accumulation at the bottom of the drill rod and ensuring continuous excavation operations.

[0031] In a further optimization of the above embodiment, the drill bit is a tapered drill bit with a tip angle of 30°-60°. This angle facilitates penetration into the soil and reduces resistance.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
