RU100620U1 - DEVICE FOR SAMPLING FROM SPECIFIED DEPTHS - Google Patents

Abstract

 A device for sampling from predetermined depths, including a rod with a sampler, made in the form of a glass with slots for sampling soil, at the end of which a drill bit is made, made in the form of a drill, and a rod rotation mechanism made in the form of a hypoid gear mounted on the rod small wheels and with a handle for rotating a large wheel, characterized in that the device is additionally equipped with a housing, on the basis of which the latches are installed, which hold the position during drilling, on the housing there is an adjuster g sampling troughs provided with slots with a set division value.

Description

The utility model relates to drilling equipment, in particular to a device for sampling soil and can be used in the production of works on taking soil from natural soil on crops.

Known soil drills containing a rod with a sampler, a rod rotation mechanism and a shock head (see ed. Certificate of the USSR No. 387243, MKI G01N 1/04, published on 08.27.1995)

The closest in technical essence is a soil drill containing a rod with a sampler, a rod rotation mechanism and a shock head. The drill is equipped with a nut mounted on the rod with a handle for extracting the drill, and the rod is made in the form of a lead screw with a rectangular double-thread (see patent for utility model RF No. 2042938 according to MKI G01N 1/04, published on 08.27.1995).

A disadvantage of the known soil drill is that it has large dimensions and is difficult to operate.

The objective of the utility model is to stabilize the position of the drill and simplify the operation of determining the depth of sampling and reduce the size of the sampler.

A device for sampling soil from predetermined depths, including a rod with a sampler, made in the form of a glass with slots for sampling soil, at the end of which a drill bit is fixed, made in the form of a drill and a rod rotation mechanism made in the form of a hypoid gear mounted on the rod small wheels and with a handle for rotating the large wheel, and the device is additionally equipped with a housing, on the basis of which there are latches that hold the position when drilling, a depth adjuster from sample boron grooves with set division price.

This task is achieved by the fact that the device is additionally equipped with a housing, on the basis of which there are mounted clamps that hold the position while drilling, on the housing there is a sampling depth gauge equipped with grooves with a set division value.

Figure 1 shows a device for sampling, side view.

Where 1 is the base, in the guide holes of which a rod 2 is inserted, interacting with the rotation mechanism 3 in the form of a hypoid gear with two small wheels 4 and a large wheel 5 connected to the handle 6. At the lower end of the rod 2, a sampler 7 is fixed. The sampler 7 is made in the form cups 8 with slots for sampling soil 9, at the end of which a drill bit 10 is fixed. A support arm 11 is fixed on the upper end of the base 1. Holes 12 are made in the stem 2 for fixing small wheels with 4 pins 13. Pins 15 are fixed on the platform 14, alive position during drilling, and the depth of sampling dial 16 provided with grooves with a division value for soil sampling at a predetermined depth.

A device for sampling soil works as follows, the lower end of the rod 2 with the sampler 7 is pressed to the surface of the investigated soil, holding the soil drill in the vertical direction with the support handle 11, rotate the handle 6, which transmits rotation through the rotation mechanism 3 in the form of a hypoid gear with two small wheels 4 and a large wheel 5, on the rod 2 with a sampler 7.

On the platform 14, pins 15 are fixed that hold the position during drilling, as well as a sampling depth gauge 16, equipped with grooves with a division price for sampling soil from a given depth. The vertical movement of the drill 6 is carried out by pressing the support handle 11 and the drill bit 10 of the sampler 7, while drilling the soil, deepens the rod 2 of the soil drill into the soil to the required depth of the positions for taking soil samples, which make the glass 8 through the slots for sampling soil 9. Then the soil the drill is raised with a soil sample.

The required depth of the position for sampling the soil is regulated by moving the rod 2, fixing it in small wheels 4 with the help of pins 13, inserting them into the holes 12.

The proposed technical solution made it possible to simplify the operation of the device by 2 times, due to the simplification of the design and the reduction of its dimensions.
