Description

The invention relates to well-known machines for milling flax by means of longitudinally grooved {x) drums with a gradually decreasing pitch of flute, which are used for coupling with grooved rollers covering a part of the circumference of each drum. The adjustment of the pressing force of the drum and rollers is carried out by means of spring-loaded bearings in which the drums are mounted. In the proposed machine, a series of drums, together with the rollers covering them, are placed at intervals for free passage of fires and impurities that are released as a result of the gradual advancement of flax stems through the machine.

The schematic drawing shows a side view of a flax milling machine:

On the sides of the frame 1, which serves as the base of the machine, vertical posts 2 are installed with longitudinal bars 3 and 4 embedded in them. Middle bars 3 are used to install bearings for corrugated rollers 5 placed three between each pair of posts 2 and at some intervals from each other for the passage of impurities from the paste. On the upper bars 4, bearings 8 are installed for corrugated drums b, coupled to the rollers 5. To adjust the pressing

the drums b and rollers 5 are designed springs 9 mounted on the upper parts of the bearings 8, having the possibility of vertical movement along the guide bolts in the lower part of the bearings. Flabby organs; the machines formed by the rollers and drums are installed in series with the same teeth or grooves and are arranged in decreasing order of the last step as the stems pass through the machine. The machine receives movement from a manual drive, consisting of two levers P, 11, pivotally attached to the frame and during its movement up and down, telling the drum to rotate b with the flywheels 7.7 by means of earrings and cranks 10.10, mounted on the drum axis. The transmission of rotation to the entire system takes place with the help of chain gears connecting the sprockets 12 mounted on the axis of the drums 6 on both sides of the latter. Flax is put into the machine from site 14, and flax washed and cleaned by machine is removed from the scoop 15.

The subject of the patent.

1. A flax milling machine using several series of longitudinally grooved drums with constantly decreasing flute bar, each of which drums on the lower part of the periphery is covered by three rollers that engage the longitudinal grooves with a drum fitted with bearings that allow the drums to change to the rollers by springs, characterized by the fact that the series of drums 12 (Fig. 1) are installed with intertals, in order to free fall

down the impurities that separate from the stems as they pass through the machine.

2. With the machine described in paragraph 1, the use of a manual drive consisting of two levers 11, 11, ends of which are pivotally fixed to the frame, are connected by means of earrings with cranks 10.10 of the axis of the drum of one of the systems, which systems are connected to each other chain drive.
