Description

Novel earth drill

Technical Field

The utility model relates to a device fetches earth, concretely relates to novel soil drill.

Background

Soil sampling has been an important task in the fields of modern agriculture, geology, water conservancy, environmental protection and the like. In order to determine the physicochemical property of a soil sample, the soil sample needs to be collected, and the current soil collection methods mainly comprise spade soil taking and soil drilling soil taking. The use of shovels to remove soil not only makes it difficult to obtain a complete soil layered structure, but also damages the soil. Use traditional soil to bore and borrow soil, though reduced the destruction to soil, nevertheless need follow supreme taking out in proper order down with the help of the soil body in the instrument with the drill bit, easily broken the completeness of soil sample to waste time and energy, the troublesome poeration.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem that the soil sample is difficult to be guaranteed when the soil is taken, and the operation is troublesome, thereby providing a novel soil drill.

When the two sampling cylinders of the novel soil drill are closed, the soil inlet end is a sharp knife edge with a double-pointed shape or a bevel oval shape or a saw-toothed shape, and the sampling cylinders can be inserted into soil conveniently. And the soil sample is taken out from the two sampling cylinders, and the soil sample can be taken out only by separating the two sampling cylinders. In addition, the surface of the sampling cylinder is provided with a ventilation opening, so that gas is conveniently discharged during soil taking, and the soil taking progress is accelerated. The buckle is arranged on the handle, so that the opening-closing type handle is prevented from being opened due to uneven stress in the soil taking process, and the stress of the soil taking rod in the soil taking process is relieved.

Detailed Description

The technical solution of the present invention will be clearly and completely described with reference to the accompanying drawings.

As shown in figure 1, the novel earth drill comprises two rotating parts 1 with the same structure, wherein each rotating part 1 comprises a handle 11, an earth taking rod 12 and a sampling cylinder 13, one end of the earth taking rod 12 is fixedly connected with the handle 11, and the other end of the earth taking rod 12 is fixedly connected with the sampling cylinder 13. The two rotating parts are connected in a hinged mode at the fixedly connected position of the soil sampling rod 12 and the sampling cylinder 13. The two handles 11 are driven into contact with each other or away from each other to effect the closing or opening of the two cartridges 13. The height of whole novel auger is 1m, but the utility model discloses not be restricted to 1 m's design.

As shown in fig. 3, the sampling cartridges 13 are semi-cylindrical structures, and when the two sampling cartridges 13 are closed, a cylindrical structure is formed. In order to improve the soil sampling efficiency, when the two sampling cylinders 13 are closed, the soil inlet end is a double-pointed sharp edge, and can also be designed into a beveled elliptical or serrated sharp edge. In order to further improve the soil sampling efficiency, the surface of the sampling cylinder 13 is provided with the ventilation ports 4, and the gas in the sampling cylinder 13 is discharged in the soil sampling process, so that the soil sampling speed is increased. When the two sampling cylinders 13 are closed, the two air holes 4 are spliced into a shape that the upper side and the lower side are semicircular, the middle part is rectangular, and the width of the rectangle is equal to the diameter of the semicircle. When the two sampling cylinders 13 are closed, the height is 20cm, the diameter is 4cm, the semi-circle diameter of the upper side and the lower side of the air vent 6 is 1.6cm, and the length of the middle rectangle is 10 cm.

As shown in fig. 2 and 4, in order to relieve the stress of the soil taking rod 12 in the soil taking process and avoid that the two handles 11 are opened due to uneven stress in the soil taking process, a buckle 2 is arranged on any one handle 11. The handle 11 is hollow cylinder, can lighten the weight of the whole soil drill, and is convenient to carry. The buckle 2 is in a semi-circular ring shape, and one end of the buckle 2 is hinged on any handle 11; when the two handles 11 contact each other, the buckle surrounds the contact position of the two handles 11, and the handles 11 are in clearance fit with the buckle. In addition, in order to facilitate the pulling out of the buckle 2, a ball-shaped handle 3 is provided on the buckle 2.

In order to more accurately take out a complete soil sample with a certain depth, sampling scales are arranged on the sampling cylinder 13 and the soil sampling rod 12.

The novel soil borrowing process is as follows:

when gathering the soil sample, the sample person contacts two handles 11 each other, and then realizes the closure of two sampling barrels 13, and rethread buckle 2 locks two handles 11, and the soil auger is T type form this moment. Rotating handle 11 makes the soil drill insert in soil, observes sampling cylinder 13 and the scale of pole 12 that fetches earth, reaches when the scale and predetermines the scale after, reverse rotation handle 11 extracts the soil drill from soil, pulls handle 3 on the buckle 2, keeps away from two handle 11 each other, and two sampling cylinders 13 also separate this moment, are X form, at this moment take out soil sample from two sampling cylinders 13.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
