Description

Technical Field

[0001] The utility model relates to the technical field of earth-drilling machines, in particular to an earth-drilling machine with a protective structure. Background Art

[0002] Forestry planting refers to the activity of planting trees in a specific area in an organized manner to achieve economic, environmental or social goals. In agricultural planting, corresponding drilling machines are required. The drilling machines can quickly drill holes under the surface and complete the planting tasks quickly. The drilling machines are usually composed of a drill bit, a drill rod and a drill. The drill bit is pushed underground by rotation, pushing or impact to achieve the purpose of drilling.

[0003] The earth-drilling machines currently on the market generally perform drilling operations by rotating drill bits and drill rods when in use. The drill rods of existing earth-drilling machines are directly exposed to the outside, and when encountering stones during the drilling operation, the gravel generated will splash around, which is easy to cause harm to the surrounding workers. Therefore, we propose a earth-drilling machine with a protective structure. Utility Model Content

[0004] The utility model aims to provide an earth-boring machine with a protective structure to solve the problems in the current market raised by the above-mentioned background technology.

[0008] Preferably, the outer sleeve of the guide rod is provided with a first spring, and the two ends of the first spring are respectively connected to the movable groove and the movable block, the two sides of the edge of the connecting sleeve are connected to a mounting seat, and a fastening bolt passes through the outer side of the mounting seat.

[0009] Preferably, a mounting cavity is provided in the middle of the bottom end of the auger rod, and limiting grooves are provided on both sides of the auger rod close to the mounting cavity, and a mounting block inserted into the mounting cavity is connected to the surface of the drill bit.

[0010] Preferably, a docking cavity is provided inside the mounting block, and a limit seat is inserted inside the docking cavity.

[0012] Preferably, a limiting rod passes through one side below the blocking block, a second spring is sleeved on the outer side of the limiting rod, and two ends of the second spring are respectively connected to the blocking block and the auger rod.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: the earth drill with a protective structure can prevent stone fragments from splashing outward during drilling operations by installing a protective cover and a connecting sleeve on the outer side of the spiral drill rod, and the protective cover can be telescopically moved up and down, so that the earth drill has a protective structure, and the two limit seats are driven to move synchronously through the mounting block and the limit groove for plugging through the mutual cooperation of the knob and the connecting rod, so that the earth drill can be easily and quickly limited to assemble the drill bit.

[0014] 1. The earth-drilling machine with a protective structure first sets the connecting sleeve and the protective cover on the outside of the auger rod, and passes through the mounting seat and the mounting plate through the fastening bolt for locking and installation. When the earth-drilling operation is performed, the protective cover on the outside of the auger rod gradually contacts the ground, and as the auger rod moves downward continuously, the protective cover squeezed by the ground moves upward along the outside of the connecting sleeve until the auger rod is taken out upward after the drilling operation is completed. At this time, the protective cover can be automatically reset downward to the initial position by the elastic force of the first spring. By installing the protective cover and the connecting sleeve on the outside of the auger rod, and the protective cover can be telescopically moved up and down, it can prevent the broken stones from splashing outward during the drilling operation, so that the earth-drilling machine has a protective structure;

[0015] 2. The earth-drilling machine with a protective structure first pushes the blocking block downward to the limit position, and then the mounting block connected above the drill bit is docked and inserted into the interior of the mounting cavity, so that the limit seat is correspondingly inserted into the interior of the docking cavity. At this time, the staff drives the connected connecting rod to rotate synchronously by turning the knob. With the rotation of the connecting rod, the two limit seats can be synchronously moved to both sides until the limit seat penetrates the mounting block and docks in the interior of the limit groove. After the installation is completed, the pushed blocking block is loosened and automatically reset to block the outside of the knob. The two limit seats are driven to move synchronously through the mounting block and the limit groove for insertion through the mutual cooperation of the knob and the connecting rod, so that the earth-drilling machine is convenient for quickly limiting the assembly of the drill bit.
