Abstract

The invention relates to the sampling of predominantly fibrous materials from the vehicle body, from the riots of the harvesting stations. The purpose of the invention is to increase the reliability of sampling a fibrous material, such as raw cotton, by keeping the ratio between various sulfur impurities unchanged and reducing the effect of the transportation process on the sample humidity. A device for sampling fibrous materials contains a working body connected to the drive engine and equipped with a cone nozzle with a bearing unit and a bearing on one side with a working body with sampling ports, turners in the form of spike rollers, in which one end is installed in a blind hole and at the other end the gear is fixed, and the length of the pegs from the base to the upper part increases. The device is equipped with a screw conveyor placed inside the transport pipe, blades located above the conveyor outlet, conveyor drive and blades, a casing hinged to the cylindrical body, the speed of rotation of the conveyor screw and blades are not equal, and the driven agitator gears interact with the pinion gear, rigidly fixed inside the cylindrical body. 2 Il.

Description

This invention relates to sampling, predominantly fibrous materials, such as raw cotton, cotton fiber, and others, from the body of vehicles, from riots of harvesting stations and cotton gin plants in the cotton industry.

The aim of the invention is to increase the reliability of sampling a fibrous material, such as raw cotton, by keeping the ratio between various trash substances unchanged and reducing the effect of the transport process on the humidity of the sample.

The device comprises a transport pipe 1, provided on one side with a nozzle 2 in the form of a cone, having windows 3, along the perimeter of the nozzle 2, the turners 4 are installed in the form of beater rolls connected via driven gears 5 to the driving gear 6 mounted on the inner surface

cylindrical housing 7, the lower ends of the digging rolls are installed in blind holes, and the top of the nozzle 2 is equipped with a taper screw 8. Inside the transport pipe 1 using a bearing unit with bearing 9 is placed a screw conveyor 10 driven by a drive 11, the transport pipe 1 is fixed inside cylindrical housing 7 using bearings 12 and bearings 13 and connected through gears 14 and 15 to the actuator 16. In the upper part of the housing 7 is hinged casing 17, covering the blades 18, which are placed above the exit of the screw conveyor 10 and Uniform drive housing 11. pomoshyo with an elastic sleeve 19 is connected with the container 20 for the sample of the fibrous material.

The operation of the device can be divided into two stages.

The first stage is the introduction of the device into the mass of fibrous material located either in the back of the vehicle or in the riots of receiving points. For this, the drive motor 16 is turned on, which drives the transport tube 1 in rotation. A screw 8 fixed on the cone nozzle 2E loosens the fibrous material and displaces it around the perimeter of the screw, the device begins to sink into the material under its own weight. At the same time gears 5 mounted on the axes of the agitator -4, interact with the driving gear 6E, which leads to rotation of the agitators 4 around their axes and at the same time around the vertical axis of the device. The rollers of the agitators 4 loosen the fibrous material, which through the windows 3 gets inside the conical nozzle 2. The device continues to penetrate into the material.

At the second stage, a sample is taken from the desired depth of the material. For this, the drive 11 is turned on and the screw conveyor 10 moves the loosened fibrous material to the outlet 1. At the same time, the blades 18, rotating in the space bounded by the casing 17, collect fibrous material and push it to the casing outlet opening, from which, under the influence of gravity

the elastic sleeve 19 enters the container 20. When the device deviates from the vertical (up to 90 °), orientation of the inlet of the casing 17 is necessary for free movement of the material. For this, the casing 17 is hinged on the cylindrical body 7. The orientation of the casing 17 to the desired position occurs independently under the action of its own weight and the weight of the elastic sleeve 19. In order for the fibrous material not to accumulate between the blades 18, their rotation speed is different from the rotation speed screw conveyor 10. Choosing these ratios, for example, in the range from 1: 2 to 2: 1 (excluding 1: 1), you can ensure stable operation of the conveyor 10.

The use of the invention will allow an objective assessment of the quality of fibrous materials, prevent artificial overestimation of the grade of fibrous materials, raw cotton in particular, due to a more accurate analysis of its moisture and contamination. The changed trajectory of the agitators compared with the known device improves the sampling productivity.
