Abstract

The invention relates to devices for sampling fibrous materials from vehicle bodies, riots and other cotton-cotton storage sites and can be used at logging points and cotton factories. The invention allows for more efficient sampling over the entire depth and to ensure a higher representativeness of the sample. The device contains two flexible belts, equipped with pegs, driving and driven drums. mounted on the ends of rectangular pipes, a drive mounted on the pipe, troughs covering the outer parts of the flexible tapes, fasteners for fastening the splines on the flexible tapes. When the device is in contact with a mass of fibrous material from the splitting material, turning on the axes in the fastening elements, they are set at an angle of 80-90 °. to the flexible ribbons, rotating towards each other, the fibrous material is captured and is fed upward through a pipe. As the fibrous material is sampled, a channel is formed in its mass through which the device, under its own weight and translational motion, is inserted into the mass of fibrous material. At a predetermined depth, the device is stopped and removed.

The invention relates to a device for sampling fibrous materials from the vehicle body, riots and other raw cotton storage facilities and can be used at cotton gates and cotton plants.

The purpose of the invention is to enable efficient sampling of representative samples of fibrous materials.

FIG. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - cone-shaped pegs and their fastening on the tape.

The device contains two flexible ribbons 1 and 2, provided with beaters 3, leading 4 and 5, and slave 6 and 7 drums fixed along the ends of a rectangular section pipe 8, in the cavity of which the one facing the other is missing. flexible tapes 1 and 2, the actuator 9, mounted on the pipe 8, chutes 10 and 11 are U-shaped, covering the outer parts of the flexible tapes 1 and 2 and mounted on the pipe 8, Tungsten 3 on the flexible tapes 1 and 2 are freely attached to the axis x 12 fasteners 13 mounted on flexible tapes 1 and 2 with screws 14.

The device works as follows.

The drive 9 of the leading drums 4 and 5 and the flexible belts 1 and 2 begin to rotate synchronously one after the other (the direction of rotation is shown by arrows). At the same time, JC turns on the drive 9 to the device in translational motion (drive translational motion is not specified). When the device is in contact with a mass of fibrous material; splittings 3, turning 12 axes: Fastening elements 13 are set at an angle of 80-90 ° to the flexible flap: there 1 and 2 and capture fibrous material, which is clamped between the | Flexible tapes 1 and 2 and. pipe 8 is fed up. In the upper part of the pipe 8, the fibrous material from the tips of the 3 flexible bands 1 and 2 is removed by a wiper and fed into a sampling unit (not indicated). As the fibrous material is sampled, a channel is formed in its mass, along which the device under the action of its own weight and incoming movement enters the mass of fibrous material. When reaching

five

At a predetermined depth, the insertion drive 9 is turned off, the translational movement is stopped and the device is removed. After the device is removed, the drive 9 is turned on again and the fibrous material remaining between the flexible tapes 1 and 2 is removed from the pegs 3 and sent to the sampler

0 (not specified). .

When the flexible belts 1 and 2 are rotated, the pegs 3, the passage, the highest point of the leading drums 4 and 5, are rotated on the axes 12 of the fastening elements 13,

5 freely hang along the flexible bands 1 and 2 when moving down and in such a strip they enter under grooves 10 and 11. When leaving U-shaped grooves 10 and 11 during the operation of the splitting 3, they come into contact with the fibrous material , rise, install ps in fasteners 13 at an angle of 80-90 to flexible tapes 1 and 2 and in this position rise. At the same time, the cross section of the channel that forms in the mass of fibrous material in the sampling process is larger than the cross section of the device, since the dripping rod is 10–30% longer than the distance

0 between flexible tapes and grooves, which facilitates the introduction of the device into the mass of fibrous material.

U-shaped troughs 10 and 11, covering 5 the outer parts of the flexible tapes 1. and 2, protect the ribbons and prevent the pegs 3 from catching the fibrous material from the upper layers as they move downwards. 0
