Description

Soil drill for artificial soil sample collection

technical field

The utility model relates to the technical field of soil sampling tools, in particular to an artificial soil sample collecting soil drill.

Background technique

In the field of agricultural resource utilization, the study of deep soil is very important. Researchers need to use soil sampling tools to sample the soil in layers, and then detect and analyze the nutrients in each layer of soil. At present, soil samples are mostly collected by soil borrowing drills. When in use, the external helical bit of the soil borrowing drill is pressed into the soil by manpower rotating the handle of the soil drilling drill to sample the soil. After the sampling is completed, the soil borrowing is lifted by the handle. The soil sample is taken out from the drill bit by using the auxiliary tool used with the soil borrow drill, and the nutrients of the obtained soil sample are tested and analyzed.

Existing soil borrowing drills have the following problems:

(1) Since the inner wall of the traditional soil drill bit is smooth, it has a large resistance to the soil during use, and requires a lot of manpower. Therefore, these soil borrowing drills can only sample the soil with relatively soft soil texture. When sampling the soil with hard soil texture, there is a large resistance, and the drill bit is not easy to enter the soil and cannot reach the required depth, resulting in inaccurate research results. , The force between the drill bit and the drill pipe is uneven and easily damaged, which is not conducive to the collection of soil samples.

(2) The traditional soil drill adopts a direct-connection design. During the artificial soil extraction process, it needs to rotate clockwise and counterclockwise in turn, that is, the soil should be rotated according to the screw direction of the drill bit to extract soil. After one rotation, the entire soil must be removed. Turn the drill in the opposite direction for a few angles before continuing to extract soil. There is a lot of useless work in the sampling process, which not only wastes manpower, but also affects the efficiency of soil borrowing.

(3) The parts of the earth borrow drill are fixedly connected, which is not convenient to carry.

SUMMARY OF THE INVENTION

Aiming at the above-mentioned prior art, the technical problem to be solved by the present invention is to provide an artificial soil sample collecting soil drill that is more labor-saving, efficient, accurate, portable and suitable for manual soil sampling, so as to solve the time-consuming and laborious process of artificial soil sampling. , sampling inaccurate and inconvenient to carry.

In order to solve the above technical problems, the utility model provides an artificial soil sample collecting soil drill, which includes a drill handle, a one-way bearing type backstop is arranged on the lower side of the drill handle, and the one-way bearing type backstop is connected to the drill pipe through a joint. The upper end of the drill pipe is connected to the upper end of the drill pipe, and the lower end of the drill pipe is connected to the drill bit through a joint. The drill bit is a hollow cylindrical structure with an opening at the bottom. The helical direction of the helical cutter head is the same.

Preferably, both ends of the drill pipe are provided with clamping protrusions; the joint is a hollow cylindrical structure, the fixed connection end of the joint is fixedly connected to the one-way bearing type backstop or the drill bit, and the movable connection end of the joint A card interface is provided, and the two ends of the drill pipe can be inserted into the movable connection ends of the joint respectively, and the clamping protrusions are inserted into the card interface.

Preferably, the upper side of the outer ring of the one-way bearing type backstop is welded to the middle of the drill handle, and the lower side of the inner ring is welded to the fixed connection end of the joint.

Preferably, the card interface is a "U"-shaped port.

Preferably, the excavation opening is a bar-shaped opening with a width of 10 mm.

Preferably, a scale is provided on the drill pipe.

Preferably, both ends of the drill handle are provided with rubber holsters.

Preferably, the pitch of the internal thread is 8mm, and the thread depth is 1-3mm.

To sum up, the above soil drill for collecting artificial soil samples, first of all, the inner wall of the drill bit is provided with an internal thread, and the lower edge is provided with a spiral knife edge. The spiral direction of the internal thread and the spiral knife edge is consistent. It can provide a force that rotates along the thread direction of the drill bit for the soil inside the drill bit, which can effectively reduce the force required for artificial soil extraction compared with the traditional soil drill using the extrusion soil extraction method. Secondly, there is a one-way bearing type backstop between the drill handle and the drill pipe. Since the artificial soil drill generally adopts the reciprocating rotary soil extraction method, during the soil extraction work, the drill handle can rotate together with the soil drill to achieve soil extraction. When turning in the opposite direction, only the handle connected with the one-way bearing type backstop is turned, which can effectively reduce the number of times of reverse rotation of the soil drill during manual soil extraction, and achieve the effect of saving manpower and improving efficiency. Thirdly, the drill bit, the drill rod and the drill handle are detachably connected through the joint, which is convenient to carry.

This new type of soil drill for collecting soil samples and the dual effect of a one-way bearing type backstop and a drill bit with internal thread can greatly reduce the labor time and labor consumption of soil drills currently used in agricultural soil research. , the parts are detachably connected through joints, which is convenient to carry. It solves the problems of time-consuming and laborious, inaccurate sampling and inconvenience in the current manual soil sampling process, and has the advantages of labor-saving, efficient, accurate, portable and suitable for manual soil sampling.
