SU42746A1 - Flax Cutter - Google Patents

Description

Apparatuses for combing flax heads are known using combing teeth located on an endless web. In the proposed device, a drum with teeth is applied, rotated in the direction opposite to the movement of the endless web, and used to clean the teeth of the latter from confusion.

The device in the form proposed by the author is an integral part of a combined machine for pulling and combing flax heads.

In FIG. 1 shows a general view of the combined maschina behind; FIG. 2 is the same side view with a partial cut; FIG. 3 is a sectional front view of the combing device; FIG. 4 - detail of the combing device.

From the individual topping sections of the machine, consisting of a pair of belts each, the worn flax enters a common horizontal conveyor 52, which is fed to an inclined conveyor 66, made in the form of an endless belt with teeth 68. With this conveyor the flax is sent to a clamp between endless ribbons 74 placed one above the other, which hold flax stems during combing of the heads and guide the combed flax to the hallway

device 75 (. The lower belt 74 is mounted on two pulleys 7J and 75, of which the pulley 7, when adjusting the tension of the belt 74, can be installed in one or another position by turning the screw rod 73. The upper belt also has a similar tension device in the form of a screw 79. For a tight flax clamp between the tapes, the rollers / are used, pressed against the upper tape by springs 80.

Pulling off the heads is performed using curved teeth 84 attached in rows to endless web 83. The latter is mounted on three rollers W4, 105 and 107 that are parallel to the direction of movement of the belts 74. Thus, the web 83 is driven in a direction perpendicular to the movement of the belts 74. In order to control the tension of the blade 83, the roller 10T can be moved in the guides J58 using a set screw 108. The stripping teeth 84 of each row are of different lengths and are set to different ones from each other. ug of the distance and, in the part of the web where the combing of the heads begins, the teeth have the shortest length and are located on. large distances from each other (Fig. 3). A drum 101 with teeth 102 is used to clean the teeth 84 from the tangle. This drum is forced to rotate in the direction opposite to the movement of the endless web 83. To prevent lateral movements of the web 83, guide arms 94 and 94a located on both sides serve to prevent lateral movement. canvases. On these arms there are ball bearings 95, along which the ends of the slats 99, which serve to secure the teeth 84 on the web 83, slide. The batted heads fall down and with the screw 109 are directed to the elevator, which are fed to the hopper 118, located at the top of the machine.

The subject matter of the invention.
