Abstract

The invention relates to the primary processing of bast cultivars, can be used for cracking hemp trusts before drying and allows for improved serviceability and productivity by mechanizing the cracking of stalks of trusts. Formed on the feeding conveyor 1, the layer of trusts moves towards the toothed disks 5, which capture the stems and accompany them in the area of the wedge stop 7. The stalks on the tip of the stop 7 are subjected to a progressively increasing bending effect, resulting in cracking of the stems. Broken stems are not retained by the tips when entering the drying chamber. 2 3.p. f-ly, 2 ill.

Description

The invention relates to the primary processing of bast crops and can be used to crack hemp trusts before drying. $

The purpose of the invention is to improve serviceability and productivity by mechanizing breaking stems trusts.

[Hi FIG. 1 shows a diagram of a pre-folded device, side view; on! FIG. 2 - the same front view.

A device for preparing hemp trusts for machining comprises a means for forming a layer 15 of sheaves from sheaves (not shown), a feeding conveyor 1 of the drying chamber 2 and a means for breaking the trusts, including the shaft 4 mounted above the feeding conveyor 1 on a shaft 20 connected to the drive 3 the sides of the vertices are gear discs 5 with rollers 6.

| Toothed disks 5 are located on the outside of the truncated rollers 6: cones adjacent 25 with smaller bases one to another (under the rollers 6 there is a wedge stop 7, spring-loaded 8. The stop 7 in the direction of movement of the stems has an increasing 3θ height To ensure a gradual increase in the efforts of breaking the stems, it is mounted on the frame by means of a hinge 9 located on the input side of the layer to prevent it from sticking in. The frame of the supply conveyor 1 has a slot 10 for passage of the stop 7 .

The device operates as follows. . 4U

Formed on the feed conveyor 1 slot. trusts moves towards the toothed disks 6, which capture the stems and accompany them in the stop zone 6. The stems on the dd point of the stop 6 are subjected to a gradually increasing bending effect, as a result of which the stems break.

After the release of the stems from zone 6 pa upo- their movement in the chamber drying py ^r 2 is carried out by the feed pins of the conveyor 1. Nadlomannye stebyi at the entrance to the drying chamber is not delayed tops so retained trusts layer perpendicularity to the direction of motion of the conveyor 1, whereby loading technology is not violated and the opportunity arises to use existing drying chambers for hemp trusts without increasing their overall dimensions.

Claims (3)

Claim 1. A device for preparing hemp trusts for machining, containing sequentially installed schwa skeleton means for forming a layer of trust, from sheaves and a horizontal feed conveyor of the drying chamber, characterized in that, in order to improve serviceability and productivity by breaking mechanization 'stems trusts, it additionally has a means for breaking the trusts, placed in the area of the feed conveyor of the drying chamber from the top of the layer and including installed above the pit yuschim on conveyor rollers associated with drive shaft in a frusto-conical lower ..... the bases adjoining one another and rigidly connected to them, toothed disks located on the side of the large roller bases, mounted on the shaft, and a spring-loaded wedge stop located under the rollers along the line of their abutment, while the frame of the supply conveyor has a slot for passage of the stop. 2. The device according to claim 1, with the fact that in the direction of movement of the layer, the emphasis has an increasing height. 3. The device according to paragraphs. 1 and 2 ,. The difference is that the emphasis is mounted on the frame by means of a hinge located on the input side of the layer.
