Description

The invention relates to the field of agriculture, namely, the grain processing industry, in particular to the control and measurement processes during storage of grain in a grain mound in warehouses of outdoor storage in terms of farms-producers of grain, for proper installation of flexible and semi-rigid sensors for various purposes (hereinafter - probe) in grain mounds to a depth of 6 meters.

Known collapsible device UM-TSH company "Contact-1" and the method of its immersion, intended for the introduction of thermal rod in the mound of the controlled product stored in the storage of floor storage. The device consists of a different number of sections made of steel pipes. The submersible section is provided with a tip with a pin for hooking the thermal suspension. In the upper section is mounted transverse handle. Intermediate sections are installed between the submerged and upper sections by means of interlocking connections, which makes it possible to quickly increase the length of the rod and, thus, change the depth of its immersion (UKT thermal test unit - 192 Operation manual. YUEL. 405226.007 RE 1).

However, for immersion of a known collapsible device, a manual method of immersion is required, namely: pressure on the handle of the upper section. This design and method of immersion does not allow to set the thermal rod to a depth of more than 1-2 meters by one person due to the high density of the grain mass at a depth, and the density increases with time as a result of caking of the grain. Under the influence of the pressure of the overlying layers of grain, individual grains come into very close contact with each other, especially in the lower layers and near-wall spaces. A grip arises between them, as a result of which the grain mass loses flowability, and it is extremely difficult to immerse a foreign object into a depth of more than 1-2 meters into it.

A device for the circulation of grain products, consisting mainly of a screw to ensure the circulation of the grain product and the drive device, causing the screw in motion. The specified device is implemented in such a way that it can be used indefinitely in time, and it does not require manual efforts to ensure the circulation of the grain product. To this end, the drive unit is connected to the support body in a fixed manner, the lower bearing surface of said support body is oriented at a predetermined angle relative to the axis of the screw. The support body has a surface size that allows it to withstand the load created by the screw during operation, and is provided with at least one blocking plate that is immersed in the grain product. (Patent number EP 1601451. Publ. 2006-12-13).

However, the known solution is not intended to control the physiological parameters of grain in the embankment, due to the lack of a probe design with sensors for various purposes, in addition to the complexity that does not allow the extension of the screw length and the hooking of the probe to the screw due to its constant rotation.

A remote control device for granaries is known, which serves to control humidity and air temperature, both inside and outside the grain embankment, which contains a data collector, an actuator that is fixedly placed in the granary, measuring device, controller, server (CN Patent 204374754. Pub . 2015-06-03).

This remote monitoring device uses digital technology to monitor granaries and allows you to carry out this process remotely, but, despite the fact that the well-known utility model is related to agriculture, it does not describe the design and installation method of the measuring device mentioned in it.

A known tool for indicating the temperature of culinary products, which contains a long cannula, equipped with a pointed end, a short tube with a slightly larger diameter than a long cannon, soldered to it and equipped with a supporting disc. Inside the needle there is a pin, at one end of which a button is mounted, and at the other end bends are made. In addition, the pin is equipped with an elastic spring. The part of the pin with bends is immersed in a low-melting substance located in the pointed part of the needle and having a melting point close to that which is to be controlled. When heated, the pointed end, to a certain temperature, the substance, turning into a liquid state, frees the pin, and under the action of the spring it extends (Patent number US 945978. Publ. 01.11.1910).

However, despite the presence of the pointed end of a cannula, the known device is not intended for use in agricultural conditions, due to the lack of a probe with measuring elements placed inside it or on its surface.

A device for monitoring the state of the stored bulk material is known, comprising a perforated housing with a lid in the upper part and with a funnel-shaped catcher in the lower part, which is equipped with sensing elements of temperature and relative humidity of air mounted in the housing, and an element of continuous counting of insects located in the area of the guide channel a funnel-shaped catcher communicated with an insect exit channel made of a material with repellent properties, with perforations in the building They are made obliquely upwards and with different diameters. In addition, the perforated part of the body is made of an attractant material (Patent No. 2038784 RU. Publ. 09.07.1995).

However, the known device is not intended for its use in obtaining information on the physiological parameters of the grain mass during its storage, due to the lack of a probe in the design, equipped with measuring sensors, and interconnected with the immersion rod. In addition, the direct task of the device is to obtain information about the physiological parameters of the grain mass, but the device is displayed as a single sensor and does not incorporate a probe in the form of an extended reinforced shell, inside and on the surface of which sensors for various purposes are placed.

A device for monitoring the temperature of grain in silos, containing a support head with a connector for connecting a measuring device and resistance thermometers, are electrically connected to each other and with the said connector, in which resistance thermometers, the frames of which are made of metal, for example brass, are placed in a heat-insulating protective pipe and attached to it, and the fasteners mentioned resistance thermometers are made of metal to ensure heat transfer from the grain to them (Patent number 2095768 RU. Pub. 1 0.11.1997).

However, the known device is not intended for its use in obtaining information on the physiological parameters of the grain mass in embankments, which follows from its name. In addition, the absence of a pointed end, the presence of a lining fixed with screws, and a supporting head, with elements placed inside, creates difficulties in introducing the device into the grain embankment.

There is a method of immersion of thin-walled steel shells with deepening into dense waterproof soil, including installation of thin-walled steel shells on the bottom of the water area, fixing vibrotechnical means on their free end by means of connecting elements and penetrating said shells into dense waterproof primer, in which vibro-technical means are made as free springless vibratory hammers, and connecting elements in the form of fork guides, the penetration of thin-walled steel shells is produced in vibro-impact low-frequency mode with rebound shock mass, while free springless vibratory hammers are suspended through rods with springs on a rigid traverse load for additional static load on dense waterproof soil and stable operation of free springless vibratory hammers (Patent No. 2549789 RU. Publ.27.04.2015) .

However, the known method is not intended for use in agriculture when the probe, equipped with sensors, is immersed in a grain mound, as it is focused on the use in construction activities using its inherent mechanisms. In addition, the objective of this method is the immersion of the structure with its subsequent stay in the environment of immersion without the possibility of subsequent extraction.

There is a method of vibration immersion into the soil of polymer sheet piping and pipes, including changing the attachment point of the vibromechanism along the axis of the submerged element, allowing to reduce the energy losses of the oscillation waves to overcome internal friction in the sheet pile material and pipes, in which the vibrator is permuted with calculating the logarithmic damping decrement of oscillations in the material of the immersed test element, obtained by analyzing vibrograms of free damped oscillations Nij and calculation on them rate decreasing amplitudes of vibrations on the boundary of each step permutation vibrator Falling velocity immersion element to a value of 0.1 m / min (Patent №2517150 RU. Publ. 05.27.2014).

However, the known method is not intended for use in agriculture when the probe, equipped with sensors, is immersed in a grain mound, as it is focused on the use in construction activities using its inherent mechanisms. In addition, the objective of this method is the immersion of the structure with its subsequent stay in the environment of immersion without the possibility of subsequent extraction.

Thermoplastic materials and temperature control devices are known that contain such thermoplastic materials in which a temperature control device is used, including a hollow cylinder, which is a monolithic molded body equipped with a lower end adapted to be inserted into a food product and can be provided with one or several clamps radially located near the lower end. In this case, the cylinder contains an annular flange located near its upper end. The flange may have different radial dimensions in order to be able to come into contact with the surface of the food element when the temperature control device is built into it. An indicator is placed in the cylinder hole, in the form of a plunger installed with the possibility of longitudinal movement inside the cylinder equipped with a spring and a thermoplastic material that has the ability to maintain the plunger in the retracted position, depending on the temperature mode (Patent No. US 7204199. Publ. 2007-04- 17).

However, the known control device is not intended for its use to control the physiological parameters of grain in grain mounds up to 6 meters due to its design: in particular, the impossibility of installing its elements in a flexible reinforced shell.
