(54) DEVICE FOR AUTOMATIC REMOVAL AND CUTTING WOOD CHIP

one

The invention relates to a device for crushing wood, intended for cutting long wood drain chips and can be used in the timber and woodworking industry.

A device chipbreaker planer, comprising a housing with a blade rotor and the loading window with the counter-knife 1.

It is also known a device for automatic removal and cutting of wood chips, consisting of a cylindrical body with loading and unloading windows and a knife rotor 2 installed inside it.

However, the described device for feeding material requires additional feeding mechanisms, have an increased energy consumption and uneven length of the resulting chips.

The purpose of the invention is to improve the accuracy of cutting chips of a certain length and reduce energy consumption.

The goal is achieved by the fact that the inner surface of the case between the loading and unloading windows has an inclined protrusion with an anvil, and the distance between the beginning of the loading window and the protrusion is greater than the distance between adjacent rotor blades, and the anvil and inclined protrusion

5 LINES.

FIG. 1 shows a device, a longitudinal section; in fig. 2 - the location of the anvil on the inner surface of the housing; in fig. 3 shows section A-A in FIG. one.

10 The device consists of a cylindrical body 1, in which a counter-tool 2 is mounted along a helical line and on bearings 3 is a knife rotor 4 with knives 5 and a pulley 6. The case has a loading window 7, the lower part of which is made in the form of a ramp 8,

15 covers 9 for bearings 3. Before the counter-blade, an inclined protrusion 10 is made. In the upper part of the housing, there is a discharge opening 11 for removing the material being cut, which is connected to the exhauster installation.

20 The device operates as follows. The chips are fed to the ramp 8 directly from the cutting member (not shown), for or in front of which the device is installed, is caught by the blades 5 of the blade rotor 4 and is pulled into the housing. where it is cut into segments of a certain length, depending on the distance between adjacent knives 5. The cut chips fall into the unloading window 11 and are removed from it by means of an exhauster installation. The shaking of chips into the body is due to the fact that the distance between the beginning of the loading window and the protrusion is greater than the distance between adjacent rotor blades. The application of the proposed device contributes to improving the accuracy of cutting chips of a certain length and reducing energy consumption during automatic removal and cutting of wood chips. Apparatus of the Invention A device for automatic removal and cutting of wood chips, consisting of a cylindrical body with loading and unloading windows and a knife rotor installed inside it, characterized in that, in order to improve the accuracy of cutting chips of a certain length and reduce energy consumption, the internal surface of the body between the loading and the narrow windows have an inclined protrusion with the counter-knife, and the distance between the beginning of the loading window and the protrusion is greater than the distance between adjacent ro knives torus, and anvil and inclined protrusion are located along a helical line.
