Abstract

FIELD: physics, measurement.

SUBSTANCE: sampling probe includes intake tube with sharpened beveled cutting edge at lower part made in the form of sharp wedge, and with flange with facet for convenient tube extraction from a hole in hay tower. A bar of lesser diameter is attached to the intake tube by the flange. The Bar consists of two parts screwed into each other. Bar surface features measurement scale for defining probe depth in hay tower. Intake tube surface features lengthwise slot for sample removal. Sample is removed by a device including a bush with rigidly handle fixed in it and sharpened rod inserted though a hole.

EFFECT: reduced labour capacity of sampling.

Description

The invention relates to a device for sampling compacted materials and can be used for sampling silage, silage from piles, pits, trenches and other storages when assessing their quality.

A known sampler [1], containing a sampling pipe made with a thread at one end, a cutting edge screwed onto the thread, a flange mounted on the other end of the sampling pipe, a shock-absorbing working element between the flange and the cutting edge and mounted for movement along the pipe the hammer. The intake pipe is made with an internal diameter of at least 50 mm, the shock-absorbing working element is made in the form of a flange, the hammer is made with a longitudinal groove for ease of movement and installation on the pipe, and the cutting part of the crown is made in the form of two oval cutters and has an internal diameter smaller by 10 mm of the internal diameter of the intake pipe.

The disadvantage of this sampler is the complexity of the design and the complexity of sampling.

A known silo sampler comprising a sampling pipe with a pointed, beveled tip at one end thereof, a reinforcing tip and a glass at the other end, a transverse insert handle for removing the sampler from the mass, a ramrod for pushing the sample out of the pipe. The sampler is injected into the mass by hammering, striking a reinforcing tip with a sledgehammer, covered with a glass [2].

The drawback of the sampler is the complexity of sampling.

The purpose of the invention is to simplify the design and reduce the complexity of sampling.

This goal is achieved in that the probe for sampling contains a sampling pipe with a pointed beveled cutting edge, a device for extracting samples. The lower part of the probe intake pipe has the shape of a pointed wedge, the angle of which is at least 30 and not more than 60 ° relative to its axis, and a smaller diameter with a measuring scale is coaxially attached to the upper part by means of a chamfer flange, and a longitudinal groove is made on its lateral surface for sample extraction, which is carried out by a device containing a sleeve with a rigidly fixed handle and an opening for a pointed rod inserted directly into the groove.

Figure 1 shows a General view of the probe for sampling; figure 2 is a device for extracting samples from the intake pipe.

The sampling probe contains: an intake pipe 1 with a pointed beveled cutting edge 2 in the lower part, which has the shape of a pointed wedge, whose angle is at least 30 and not more than 60 ° relative to the axis of the probe pipe 1, and in the upper one, flange 3 with bevel 4 , necessary for the convenience of removing the pipe 1 from the well in a hay mass, through which the pipe 1 is coaxially attached to the rod 5 having a smaller diameter. For ease of operation, the rod 5 consists of two parts screwed into each other, the length of each of them is 1 m. On the surface of the rod 5, a graduated scale 6 is applied (risks every 10 cm) to determine the depth of the pipe 1 in the hay mass. A longitudinal groove 7 is made on the surface of the intake pipe 1 for sample extraction, which is carried out by a device containing a sleeve 8 with a rigidly fixed handle 9 and a pointed rod 10 inserted through an opening 11 located opposite the handle 9 of the sleeve 8 in the longitudinal groove 7 of the intake pipe 1 and performing function of the second handle and sample ejector.

Sampling of silage, silage is as follows. First, two components of the rod 5 are screwed into each other, each of which is 1 m long, which is necessary for sampling from trenches in accordance with GOST 27262-87 to a depth of 1.5-2 m. After that, the probe for sampling is taken into hands behind the rod 5 and sharply move downward perpendicular to the surface of the feed. In this case, the intake pipe 1 with its cutting edge 2, having the shape of a pointed wedge, the angle of which is not less than 30 and not more than 60 ° relative to the axis of the tube 1 of the probe, cuts into the feed. The cut-off part of the haylage enters the intake pipe 1. Due to the fact that the rod 5 attached to the intake pipe 1 has a smaller diameter, and the flange 3, by means of which this fastening is made, is chamfered 4, the probe is taken out of the silo formed without special efforts well trench. After that, the probe again thrusts into the feed. This continues until the intake pipe is completely filled. The probe is removed from the well and abut with a wedge of the intake pipe 1 in the container for sampling. The sample from the pipe 1 is removed using a device containing a sleeve 8 with a rigidly fixed handle 9 and a pointed rod 10. The sleeve 8 with a handle 9 is moved along the pipe 1 to its upper part. Through the hole 11, opposite the rigidly fixed handle 9, a pointed rod 10 is inserted into the longitudinal groove 7 of the intake pipe 1. When the handle 9 and the rod 10 are pressed sharply, the sleeve 8 moves downward along the pipe 1 and the sample is removed. After that, the sampling process from the deeper layer of haylage continues in the same sequence. The depth of the probe is determined according to a measuring scale 6 (risks applied every 10 cm on the surface of the rod 5).

The proposed design of the probe for sampling silage, silage is simple and provides easy penetration into the controlled mass, portioned (layer-by-layer) sampling to a depth of 1.5-2 m and reducing the complexity of the working process.
