The invention relates to controlling the properties of textiles and can be used in the cotton gin industry.

A device for determining the grade of raw cotton, mainly in the vehicle body, is known, comprising a pipe with a cone-shaped lug, having perforations around the circumference, a loading plate, a medium loosely mounted on the pipe, creating an environment that acts on cotton raw and is installed at the inlet of the pipe, and measuring unit. In this case, the means for creating a raw cotton effecting on cotton is made in the form of an air blower and an associated air duct with an integrated diaphragm l,

A disadvantage of the known device is the low accuracy of the measurements, due to the low sensitivity of the device to the change in variety.

The purpose of the invention is to improve the measurement accuracy.

The goal is achieved by the fact that in a device containing a pipe with a cone-shaped tip with perforations around the circumference, a loading plate, freely mounted on the pipe, means for creating impacts on raw cotton installed at the pipe inlet, and a measuring unit, means for creating On raw cotton, the medium is made in the form of a series-connected generator of electrical oscillations and a converter of electrical oscillations into sound. perforation, wherein the tube is provided with a sound insulating plate and the transducer acoustic vibrations into electrical established between planes arrangement of perforations and converter sound vibrations into electrical connected to the measuring unit.

The drawing shows a diagram of a device for determining the grade of raw cotton.

The device contains a generator of 1 electrical oscillations connected to a transducer 2 electrical oscillations in sound, mounted on the inlet of a pipe 3 with a cone-shaped tip, a loading plate 4, freely mounted on the pipe 3, perforations 5 and b, made around the circumference of the pipe 3, soundproofing plate 7 and a sound vibration to electric converter 8 installed between the perforation planes 5 and 6, a measuring unit 9 connected to a sound vibration converter 8 in electric.

The device works as follows.

The tube 3 is introduced into the raw cotton in the vehicle body, and the raw cotton is compacted by the loading plate 4. The electrical oscillations excited by the generator 1 are converted by the transducer 2 into sound vibrations that are directed into the tube 3. Then the sound vibrations bending around the soundproofing plate 7, exit the perforation holes 5 and act on raw cotton. The sound vibrations transmitted through the raw cotton are transmitted through the perforations 6 to the transducer 8, where they are converted into electrical oscillations. The electric signal from the converter 8 enters the measurement unit 9, in which, depending on the signal size, the grade of cotton is determined.

The economic effect of using the proposed device is determined by the accuracy of the measurement of the raw cotton variety.
