[0025] Furthermore, the feeding mechanism includes a worm gear reducer 11 arranged on the lower frame 1, a handwheel 10 and a driving sprocket 4 connected to the worm gear reducer 11, an intermediate redirecting sprocket 18 arranged next to the driving sprocket 4, a lower redirecting sprocket 2 arranged at the bottom of the lower frame 1, and an upper redirecting sprocket 13 arranged on the upper part of the upper frame 9. The driving sprocket 4, the intermediate redirecting sprocket 18, the lower redirecting sprocket 2, and the upper redirecting sprocket 13 are connected by a chain 19.

[0026] During operation, the hand wheel 10 drives the driving sprocket 4 to rotate through the worm gear reducer 11, thereby driving the engine fixing seat 14 to slide up and down along the guide column 3 through the chain 19, and the effective stroke is 1 meter.

[0027] The drill bit 15 is equipped with various specifications of ∮60mm, ∮80mm, ∮100mm, ∮120mm, and the drilling depth can reach 1 meter. The drill head is equipped with a movable blade that can cut off the tree root drill blade holder to reduce damage to the root system. The drill bit can be easily disassembled and assembled on the engine to meet different aperture requirements. Preferably, the drill blade holder is a groove structure, and the groove structure and the drill head are movably connected to the movable blade through a pin.

[0028] Further, the lower frame 1 is connected to the upper frame 9, and the lower frame 1 is provided with a cone tip 6 to stabilize the equipment, and a scale 7 to judge the drilling depth.

[0030] The working principle of the semi-automatic ground punching device for forestry of the present invention is as follows:

[0031] The user selects a suitable drill bit according to the operation requirements and installs it on the engine, starts the engine, and drives the active sprocket to rotate and descend the drill bit by operating the hand wheel to perform drilling operations on the soil. During the drilling process, the movable blade can effectively cut off the roots of the trees encountered, reducing damage to the roots. After the operation is completed, the drill bit is lifted and replaced in the storage box, and the drilling machine is moved to the next operation point to continue the operation.

[0032] The operating steps of the semi-automatic ground punching device for forestry of the present invention are as follows:

[0033] Start the engine and move the equipment to the drilling position; shake the handwheel of the feed mechanism and adjust the drill bit to the center of the drilling; increase the engine throttle to rotate the drill bit and drill down to the required depth; reduce the engine throttle to idle speed and stop the drill bit from rotating; shake the handwheel of the feed mechanism in the opposite direction to lift the drill bit to the upper limit position to complete the drilling.

[0034] Soil improvement operations were carried out at a certain forestry base, and the semi-automatic ground drilling device of the present invention was used for drilling. First, select the appropriate drill bit specifications according to the on-site soil conditions and the distribution of trees. Then, start the engine and move the equipment to the predetermined drilling position. According to the operating method steps, shake the handwheel handle of the feed mechanism to adjust the drill bit position, and gradually increase the engine throttle to perform the drilling operation. During the drilling process, the drill bit smoothly penetrates the soil, and the movable blade effectively cuts off the roots of the trees encountered. After the drilling is completed, reduce the engine throttle and shake the handwheel handle of the feed mechanism in the opposite direction to raise the drill bit to the upper limit position. The entire drilling process is fast, accurate, and causes little damage to the root system. After a period of use, the soil permeability of the forestry base has been significantly improved, the growth rate of the trees has been accelerated, and the overall growth condition is good.

[0035] The semi-automatic ground drilling device for forestry of the present invention has the characteristics of efficient drilling, flexible drill bit replacement, easy mobility, easy maintenance, etc., which can significantly improve the efficiency and quality of soil drilling operations, and provide strong support for forestry soil improvement and nutrient bar placement. The specific advantages are as follows:

[0036] High efficiency: Semi-automatic operation mode greatly improves punching efficiency and reduces manual labor intensity.

[0037] Flexibility: Drill bits of various specifications are available to meet the drilling needs of different diameters and depths.

[0038] Protective: The movable blade design on the drill head effectively reduces damage to the tree roots.

[0039] Convenience: The design of the wheel device and drill bit storage box makes the equipment movement and drill bit replacement more convenient.

[0040] Accuracy: The frame scale design helps to accurately judge the drilling depth and improve the drilling quality.

[0041] Promote tree growth: Improving soil permeability by drilling is beneficial to the respiration and growth of tree roots, and improves the tree's resistance to stress and yield.
