Abstract

FIELD: agriculture.

SUBSTANCE: device for soil sampling comprises a cylindrical tube with a sharpened cutting edge, a three-rod fork, and handles. The device is provided with an intake cylindrical cup 1 with the sharpened cutting edge 2 in its lower part and adapted to extract a sample, comprising a pusher 8 located inside of the intake cup 1, rigidly connected by the fork of three rods 9, freely passing through openings 12 of the cup lid, to the flange 10 with a hub 11 over the cup at an angle 120° relative to each other, having the ability to move along the rod 5 of the device. And mounting on the soil surface and extracting from it is carried out by the handles 7 of the impact tip 6 fastened to the upper part of the rod 5 of the device. Filling the intake cup 1 with the sample and its removal is carried out by impacts on the tip 6 of the rod 5 and the flange 10 of the device to extract the sample, fixed on the lower edge of its hub 11 relative to notches of the dimensional scale 13 applied to the rod 5 of the device.

EFFECT: improving quality of soil sample of undisturbed structure and simplification of design.

Description

The invention relates to devices for sampling various soils and can be used for laboratory studies of their physico-mechanical properties.

A known sampler [1], including a glass with an external screw-blade winding, cutters on the lower end and a cover on the upper end, a core-receiving sleeve located in it, a cover of a core-receiving sleeve with a rod at the end and a petal sample cutter with elastic curved elements. The glass is made with through longitudinal grooves, and the sleeve is mounted movably with the possibility of longitudinal movement relative to the glass and is equipped with a compression ring mounted coaxially with it with a sharpened leading edge, while the elements of the petal cutter are rigidly fixed to the outer side of the glass and are located in its through longitudinal grooves, and their lateral cutting edges are made with direct sharpening in the direction of drilling the glass.

The disadvantage of this sampler is the design complexity.

A device for sampling sphagnum peat soils [2], including a cylindrical pipe with a sharpened end, cutting knives with handles and rotary handles. The body of the device is made of a thin-walled, smooth inside and externally cylindrical pipe with thickened lower and upper ends, the lower thickened end of the pipe has cutting teeth with different negative cutting angles, sharpened from the outer side around the perimeter, and holes for input from the outer side of the two cutting knives, having stiffeners along the entire length and bent at an angle of 45-60 ° wedge-shaped ends sharpened on both sides, and the upper thickened end of the pipe is equipped with recesses with locks. The device is equipped with a fixing three-rod plug.

The disadvantage of this device is the design complexity and obtaining a soil sample of a disturbed structure.

The purpose of the invention is to improve the quality of the soil sample undisturbed structure and simplify the design.

This goal is achieved in that the device for sampling the soil includes a cylindrical pipe with a sharp cutting edge, a three-rod fork, handles. The device is equipped with a cylindrical intake nozzle with a sharp cutting edge in its lower part and a sample extraction device containing an ejector located inside the intake nozzle, rigidly connected by a plug of three rods freely passing through the nozzle cover openings to the flange with a sleeve above the nozzle at an angle of 120 ° relative to each other, having the ability to move along the rod of the device, and installation on the surface of the soil and removal from it is carried out by means of shock tilt handles nick fixed in the upper part of the rod device, and filling the sample intake nozzle and its removal due to shocks produced by the tip of the rod and flange means for extracting the sample, fixed on the lower edge of its bushing with respect to scratches dimensional scale deposited on the rod of the device.

Figure 1 shows a General view of the device for sampling soil, figure 2 is a top view of figure 1.

A device for sampling soil contains: a sampling cup 1, equipped with a pointed cutting edge 2 and a groove 3 in its lower part, a cover 4 in the upper, rigidly connected to the shaft 5, equipped on the opposite side with an impact tip 6 with two handles 7. Device for sampling soil samples are equipped with a device for extracting them from the glass 1, containing a pusher 8 located inside the glass 1 with the possibility of moving up and down. The ejector 8 is rigidly connected by a fork of three rods 9 with a flange 10 above the intake cup 1 at an angle of 120 ° relative to each other. The flange 10, in turn, is rigidly connected to a sleeve 11 that moves freely along the rod 5. The cover 4 of the cup 1 has three holes 12 for passing the rods 9 therein and to move the pusher 8 attached to them without distortions inside the cup 1. Prior to sampling, the pusher 8, rigidly connected to the rods 9, the flange 10 and the sleeve 11, is in the glass 1 in the lower position and abuts against the groove 3. As the sample accumulates, the ejector 8 of the device for its extraction moves up inside the glass up to the stop in the roof Ku 4, and its content of the soil determine the position of the lower edge of the sleeve 11 relative to the scale 13 of the rod 5.

A device for sampling soil works as follows. The device with a sharp cutting edge 2 of the intake cup 1 by means of the handles 7 of the shock tip 6 is mounted vertically on the soil surface. Before starting work, the ejector 8 of the device for extracting soil samples from the glass 1 is in the glass 1 in the lower position and rests against the groove 3. Holding the device by the handle 7, at the same time make a blow with a sledge hammer on the tip 6 of the rod 5 and thus introduce the glass 1 to its entire height in the soil. During the introduction of the cup 1, the ejector 8 gradually moves upward from the groove 3 into the cover 4 of the cup 1 and simultaneously moves the flange 10 with the sleeve 11 along the rod 5 through the rods 9. The amount of filling the cup 1 with soil is determined by the position of the lower edge of the sleeve 11 relative to the measured scale 13 of the rod 5. After the sampling cup 1 is filled with a soil sample, the device for the handles 7 is removed from the soil. The device is placed over any container and hammer blows (sledgehammers) along the flange 10 move the device for extracting the soil sample down along the rod 5. In this case, the ejector 8 removes the soil sample from the glass 1 and rests against its groove 3. The device is ready for further operation . To select soil from a deeper horizon, the intake cup 1 of the device is installed in the formed well and all operations are repeated again.
