Description

A new type of soil drill

technical field

The utility model relates to the technical field of earth-borrowing tool equipment, in particular, the utility model relates to the technical field of a novel earth-borrowing drill device.

Background technique

At present, the manual earth-borrowing drills mainly powered by human body basically belong to the smooth surface of straight inner and outer wedges in structure, and the cutting edges are flat cutting edge, inclined cutting edge and rotary cutting edge; the operation mode can be divided into direct pressure type and spiral type. And gravity hammer type three. Due to the limitation of manual force application, the combination of the above structures and operation methods is not enough to effectively overcome the resistance of the soil body, and there are still great difficulties in soil extraction.

Contents of the invention

The structure of the soil drill is simple, easy to use and strong in practicability .

The utility model solves its technical problem and realizes by taking the following technical solutions:

The utility model provides a novel earth-borrowing drill, which consists of a drill bit, a drill rod, a movable pedal, a pipe support and a handle. Among them, the drill bit has a cylindrical structure, and the cutting edge at the tip of the drill bit is a helically distributed sawtooth. The sawtooth belt has a certain radian in the shape of a plow, and the sawtooth forms a certain angle with the side of the cylinder. The entire knife edge is continuously distributed with 3 serrations at equal intervals along the circumferential surface; There is a slot on the side wall of the drill bit; a steel pipe that can slide and rotate on the drill pipe is welded at one end of the pedal; a pipe support that is the same as the pedal steel pipe and can slide independently is provided on the drill pipe. It can slide on the drill pipe or can be fixed on the drill pipe by tightening its butterfly screw according to the needs. There is a hole with a thread opening on the side of the pipe support and a nut with the same thread opening welded at the hole. There is a butterfly screw on the nut; the handle and the drill pipe are in a "T" shape.

In the utility model, the sawtooth belt of the new earth-borrowing drill has a certain radian and is in the shape of a plow. The depth is preferably 1.5cm-2cm, and the angle with the side of the cylinder is 60°. Sliding and rotating steel pipes.

In the utility model, the strip-shaped grooves sealed all around are arranged on the side wall of the drill bit for taking out the soil sample from the drill bit for convenience.

During the use of the new soil-absorbing drill provided by the utility model, hold the "T" handle and rotate the soil drill clockwise and downward forcefully, and at the same time step on the pedal downward forcefully, so that the tip of the drill bit can penetrate deeper into the soil more easily. In addition, according to the depth of the soil drill into the soil and the user's needs, the positions of the pipe support and the foot pedal can be adjusted arbitrarily so as to take soil.

The material used in the novel soil auger provided by the utility model is stainless steel, which ensures hardness and sharpness, and avoids corrosion, thereby reducing the frictional resistance when going deep into the soil layer, and avoiding the contamination of soil samples by rust.

Beneficial effects of the utility model: the new soil-absorbing drill provided by the utility model can make good use of the weight of the human body while combining hands and feet to exert force to the maximum; its plow-shaped sawtooth can better cut plant roots including woody roots. plant root system; its slidable foot pedal is convenient to step on and does not affect the depth of soil borrowing; the new soil borrowing drill provided by the utility model is simple in structure, small in size, light in weight, low in cost, simple in operation, and does not need auxiliary tools. It has the advantages of firmness, durability, long service life, guaranteed accuracy of soil extraction, strong practicability, and convenient portability.

Detailed ways

Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.

As shown in Figure 1-3, a kind of novel earth-borrowing drill comprises drill bit (6), drill rod (2), movable pedal (3), steel pipe, pipe holder (4) and handle (1) and forms. Among them, the drill bit (6) has a cylindrical structure, and the knife edge (8) at the tip of the drill bit (6) is a helically distributed sawtooth. 3 serrations are distributed at intervals. In addition, a slot (7) is provided on the side wall of the drill bit (6); one end of the movable pedal (3) is welded with a steel pipe that can slide and rotate on the drill pipe (2); The drill pipe (2) is equipped with a pipe support (4) which is the same as the pedal steel pipe and can slide independently. The side of the pipe support (4) has a hole with a thread opening and a same thread opening is welded at the eye. Nut, and wear a butterfly screw rod (5) on the nut; Handle and drilling rod (2) are " T " type structure.

In the utility model, the sawtooth belt of the novel soil-borrowing drill has a certain radian and is in the shape of a plow. A steel pipe that slides over the drill pipe (2).

In the utility model, the strip-shaped groove (7) sealed all around is arranged on the side wall of the drill bit for taking out the soil sample from the drill bit (6) for convenience.

During the use of the novel earth-absorbing drill provided by the utility model, hold the "T" handle (1) clockwise and forcefully rotate the soil drill downward, and at the same time, the movable pedal (3) exerts force downward, so that the drill bit ( 6) It is easier for the apex to go deep into the soil. In addition, according to the depth of the soil drill into the soil and the user's needs, the positions of the pipe holder (4) and the movable pedal (3) can be arbitrarily adjusted so as to take soil.

The material used in the novel soil auger provided by the utility model is stainless steel, which ensures hardness and sharpness, and avoids corrosion, thereby reducing the frictional resistance when going deep into the soil layer, and avoiding the contamination of soil samples by rust.

As mentioned above, the utility model can be better realized.
