[0002] Post hole diggers are specialized machines used for quickly digging holes for afforestation and fertilization in mountainous, hilly, and gully areas. They liberate people from heavy manual labor and are widely used in afforestation, planting orchards, building fences, and fertilizing fruit trees in autumn. They are powerful, aesthetically pleasing, comfortable to operate, require low labor intensity, are suitable for various terrains, are highly efficient, and convenient for field operations. Post hole diggers are also increasingly widely used in landscaping construction.

[0003] The existing posthole diggers are mostly handheld, requiring manual operation to stabilize and press the machine during digging. This makes operation difficult and requires at least two people. Maintaining stability during digging consumes a lot of physical strength, significantly increasing the burden on workers and posing safety hazards. The reaction force generated during digging acts directly on the workers' hands, and improper operation can cause the machine to tilt or even slip out of their hands, resulting in loss of control. Furthermore, the existing posthole diggers, with their spiral blades, throw out mud and sand during the digging process, impacting the surrounding environment and hindering subsequent backfilling.

[0015] Reference Figure 1-3 A hole-digging machine for landscaping construction includes a drive unit 1 and a spiral blade 4. The drive unit 1 generally uses a gasoline engine and is equipped with a small fuel tank to store gasoline, or it uses an electric motor with a battery. An output shaft is located on the lower side of the drive unit 1, and the spiral blade 4 is fixedly connected to the output shaft. The output shaft drives the spiral blade 4 to rotate, completing the drilling and hole-digging work. The bottom of the spiral blade 4 is conical to improve drilling stability. A protective sleeve 2, adapted to the spiral blade 4, is located on the lower side of the drive unit 1 to collect and gather mud and sand, preventing mud and sand from flying out. The top of the protective sleeve 2 is detachably connected to the outer shell of the drive unit 1, and the inner wall of the protective sleeve 2 is adapted to the spiral blade 4. When the blade 4 rotates, the lower blade cuts the soil. The cut soil is thrown against the hole wall under the action of centrifugal force and rises along the spiral blade under the action of friction, entering the protective sleeve 2. The lower side of the protective sleeve 2 is provided with a quick-release sleeve 3, and the outer wall of the protective sleeve 2 is provided with a pin. The quick-release sleeve 3 has a groove that matches the pin. The pin slides in the groove. The groove is stepped. The pin and the groove cooperate to realize the quick disassembly and installation between the quick-release sleeve 3 and the protective sleeve 2. The quick-release sleeve 3 and the protective sleeve 2 also serve to protect the spiral blade 4. In the early stage of digging, the quick-release sleeve 3 plays a role in gathering mud and sand and protection. In the later stage of digging, when the pit is deeper, the protective sleeve 2 is used for protection and gathering of soil. A frame is provided on one side of the drive unit 1 to facilitate the movement of the equipment and protect the construction personnel from loss of control of the post hole digger, which could lead to a safety accident. The frame includes a base frame 6, a slide rail 7, and a limiting guide tube 8. The base frame 6 and the slide rail 7 are perpendicular to each other and are welded together. The lower ends of the slide rail 7 and the limiting guide tube 8 are fixedly connected to the base frame 6. There are two sets of slide rail 7 and limiting guide tube 8, which are parallel to each other. A connecting frame 9 is provided on the top of the slide rail 7 and the limiting guide tube 8. A push-pull handle 10 is provided on one side of the top of the limiting guide tube 8 for the operator to hold and control the movement of the post hole digger. A slider 11 is provided on the slide rail 7, and the slider 11 is slidably connected to the slide rail 7. A lifting handle 13 is provided on one side of the slider 11 for manual operation of the slider 11 to slide up and down. A mounting bracket supporting the drive unit 1 is provided on one side of the slider 11. The mounting bracket is U-shaped and fixedly installed on the lower side of the drive unit 1. A strip hole is opened on the limiting guide tube 8. A bolt 12 passing through the strip hole is provided on one side of the slider 11. The bolt 12 is slidably connected to the limiting guide tube 8. The bolt 12 and the slider 11 are threadedly connected to lock the limiting guide tube 8. A positioning device 81 is provided on the limiting guide tube 8. The positioning device 81 includes... The arc-shaped block and positioning bolt are tightened to clamp the limiting guide tube 8, thus fixing the positioning device 81 to the limiting guide tube 8. A spring is provided inside the limiting guide tube 8 between the bolt 12 and the positioning device 81. The two ends of the spring are connected to the bolt 12 and the positioning device 81 respectively to support the bolt 12 and raise the slider 11, thereby raising the drive unit 1 and making the operation more stable. When working, the construction personnel press down the lifting handle 13 to drive the slider 11 to slide, thereby pressing down the drive unit 1 and the spiral blade 4. The drive unit 1 simultaneously drives the spiral blade 4 to rotate to perform the digging work. The base frame 6 is located below the drive unit 1. The base frame 6 has a clearance hole in the middle that is compatible with the spiral blade 4, so that the spiral blade 4 can pass through. The base frame 6 has wheels on the side near the slide rail 7 for easy movement. The other side of the base frame 6 has positioning pins 5 to fix the frame when digging, so as to prevent the reverse force from causing the drive unit 1 to lose control when the spiral blade 4 is obstructed, and at the same time improve the reliability of digging.

[0016] In this embodiment, the construction worker marks the location where a pit needs to be dug, moves the pit digger, aligns the spiral blade 4 with the pit location, and inserts the positioning pin 5 into the soil to achieve positioning. According to the pit depth, the height of the positioning device 81 is adjusted, and then the drive unit 1 is turned on to drive the spiral blade 4 to rotate. During the initial pit digging, the quick-release sleeve 3 can be retained to prevent mud and sand from splashing. The operator slowly presses down the lifting handle 13, and the slider 11 overcomes the spring force and moves down, so that the spiral blade 4 contacts the soil and digs the soil. The mud and sand enter the protective sleeve 2 under the action of the spiral blade 4. After the pit is dug, the spiral blade 4 rotates slowly. At the same time, the operator releases the lifting handle 13. Under the action of the spring, the drive unit 1 and the spiral blade 4 move up and then move to one side. The drive unit 1 controls the spiral blade 4 to rotate in the opposite direction to pour out the mud and sand, which is convenient for subsequent filling or treatment.
