Description

 The invention relates to the field of processing of fibrous materials, for example wood, in particular to devices for the selective separation of fibers or their disclosure.

 A device for processing fibrous material [1], containing a housing with a rotor equipped with an unbalanced vibrator.

 The main disadvantage is that the material enters the working cavity of such a machine only due to gravity, since the smooth surface of the rotor does not contribute to its capture and transportation along the working cavity. Hence the low performance of the device.

 A device for processing fibrous material [2], which is accepted as the closest analogue, is also known, comprising a housing with a loading funnel, a working cavity located under the loading funnel and formed by a housing and a rotor located inside it, equipped with a drive in the form of an unbalanced vibrator, and a loading auger, mounted in housing bearings.

 A disadvantage of the known device is the placement of the auger in the working area, which makes it difficult to tighten the material from the receiving funnel into the working cavity, and also reduces the effect of transportation due to the swing of the auger and the separation of its surface from the material. Thus, even the presence of a screw does not allow to increase the productivity of the device to the right extent. In addition, when processing long-fiber material, the working cavity in the upper part often overlaps with long fibers, which prevents the material from passing through the working cavity of the device, resulting in a decrease in the productivity of the device.

 The problem solved by the invention is to create a device for processing fibrous materials with improved performance.

 The technical result, which consists in eliminating these drawbacks in the invention, comprising a housing with a loading funnel, a working cavity located under the loading funnel and formed by the housing and placed in it by a rotor equipped with a drive in the form of an unbalanced vibrator, and a loading auger mounted in the bearings of the housing is achieved due to the fact that the loading auger is located in the loading funnel, and a drive clutch is installed between the loading auger and the rotor.

 The invention additionally has a grinding chamber mounted in a feed hopper, knives attached to the bottom of the screw, and a grill mounted under the knives.

 The invention additionally has a grinding chamber mounted in a feed hopper, a grate attached to the bottom of the screw, and knives mounted under the grate.

 The device (see Fig. 1) includes a housing 1 with a loading funnel 2, a rotor 3 with an unbalanced vibrator 4, a loading auger 5 located in a loading funnel 2. A screw 5 is installed in the bearings 7 of the housing 1 between the loading auger 5 and the rotor 3 mounted drive clutch 6. The unbalanced vibrator 4 is connected by a transmission to the engine 8. Between the working surface of the rotor and the inner working surface of the housing, a working cavity 9 is formed.

 In FIG. 2 shows a device with an additional grinding chamber 10 made in a loading funnel equipped with knives 11 attached to the bottom of the screw 5 and a grill 12 mounted under the knives.

 In FIG. 3 shows a device with an additional grinding chamber 10 attached to the bottom of the screw of the grate 12 and knives 11 mounted under the grate.

 The device operates as follows.

 The motor 8 through the transmission rotates an unbalanced vibrator 4, as a result of which a centrifugal unbalance force is created, causing the rotor 3 of the device to make a gyration movement, while the rotor, as a result of rolling around the body through a layer of material, rotates around its axis in the direction opposite to the unbalance rotation. The rotation of the rotor 3 through the clutch 6 is transmitted to the screw 5, which moves the material from the feed funnel into the working cavity 9, where the material is subjected to selective separation of the fibers.

 The long-fiber material, carried away by the screw from the loading funnel, is subjected to preliminary processing (cutting with knives on the grate or under the grate in the additional grinding chamber 10) and is pressed through the holes in the grate into the working cavity 9, where it is also subjected to pressure by the rotor, as a result of which the fibers are selectively separated . Moreover, depending on the required length of the divided fibers, the knives in the grinding chamber can be installed above the grate (to obtain more shortened divided fibers) or under the grate (to obtain less shortened divided fibers).
