Description

A convenient device for collecting undisturbed soil

technical field

The invention relates to a soil collecting device, in particular to a device for conveniently collecting undisturbed soil.

Background technique

In soil environmental testing, how to collect undisturbed soil samples quickly, conveniently and completely has always puzzled scientific researchers. At present, most of the manual soil fetchers commonly used are in the form of intubation, that is, the drill bit is inserted into the soil sampling from top to bottom through pressure. However, due to the special physical properties of the soil, and during the soil collection process, the soil is often accompanied by gravel. , grass roots and other substances, it is difficult for the cutter of the traditional manual soil fetcher to cut down continuously, and it is necessary to find a new position before cutting and sampling the soil, which is time-consuming and laborious. In addition, the intubation structure is unreasonable, and it is difficult to intubate during the collection process. After the soil sample is collected, it is easy to squeeze and deform the soil column in the tube due to the different soil texture. The height of the soil column after removal is often smaller than the actual height. Destroyed, sometimes the soil will fall off, and the soil sample cannot be taken out completely. Therefore, be badly in need of developing a kind of device of rapid vertical collection soil undisturbed soil.

A convenient device for collecting undisturbed soil, which consists of a handle rod, a drill body, a connecting valve, a cutting drill bit and a bulldozing body, the handle rod is arranged horizontally, the drill body is vertically arranged below the handle rod, and the handle rod and the drill body Fixed connection, the lower end pipe of the drill body is provided with an internal thread, and the bulldozing body is arranged under the drill body. The internal thread is threadedly connected with the screw rod, and the cutting bit is sequentially composed of a joint pipe, a drilling pipe and a serrated blade from top to bottom, and the cutting bit is connected with the bulldozing body through a connecting valve.

Further, the handle rod is a solid cylinder.

Further, the drill body is a hollow cylinder, an air outlet is provided above the hollow cylinder of the drill body, and a scale is provided vertically on the outer surface of the drill body.

Further, the support body is provided with a bulldozing body connection hole, and the joint pipe is provided with a drill bit connection hole.

Further, the joint pipe, the drill pipe and the serrated edge of the cutting drill bit are integrally made, and the serrated edge is arranged in a serrated shape along the bottom edge of the drill pipe.

Further, the screw rod, the support body and the bulldozing disc of the bulldozing body are integrally made.

The present invention has the beneficial effect compared with prior art:

1. The bottom of the cutting bit of the present invention is provided with a jagged cutting edge, and the soil inside and outside the cutting bit is peeled off by rotating the handle rod, which can avoid the problems of broken soil pillars and extrusion deformation during the collection process.

2. In the process of collecting soil samples, the present invention can keep the surface soil intact, and at the same time, the soil section with gravel and plant roots can also be sampled quickly and completely, saving time and effort, and improving work efficiency.

3. Press down on the handle bar to push the soil sample out of the bulldozer, which is convenient for the complete removal of the soil sample and sampling of different layers of soil.

detailed description

Specific Embodiment 1: This embodiment is described in conjunction with FIGS. 1 to 7. This embodiment includes a handle rod 1, a drill body 3, a connecting valve 4, a cutting drill bit 5, and a bulldozing body 6. The handle rod 1 is horizontally arranged, and the drill body 3 It is vertically arranged under the handle rod 1, and the handle rod 1 is fixedly connected with the drill body 3. The lower end tube of the drill body 3 is provided with an internal thread, and the bulldozing body 6 is arranged under the drill body 3. The screw rod 9, the support body 14 and the bulldozing disk 8 are in turn, the drill body 3 is threadedly connected with the screw rod 9 through an internal thread, and the cutting drill bit 5 is sequentially composed of a joint pipe 11, a drill pipe 12 and a serrated blade 13 from top to bottom, cutting The drill bit 5 is connected with the bulldozing body 6 through the connection valve 4 . The handle bar 1 is a solid cylinder, and the handle bar 1 is made of high manganese steel rod. The drill body 3 is a hollow cylinder, an exhaust port 2 is arranged above the hollow cylinder of the drill body 3, and a scale is arranged vertically on the outer surface of the drill body 3 . The drill body 3 has a length of 50 cm, an inner diameter of 5 cm, and a wall thickness of 0.5 cm.
