Abstract

This invention relates to the woodworking industry. The purpose of the invention is to increase productivity when cutting wood waste and to improve its loading into the receiving device. The disastrous machine consists of a drum 1, a mine-type receiving device 2, a frame 6, a fixed wall 3 or a moving wall 4 driven by a hydraulic cylinder 5. Waste falling onto the rotating drum 1 with knives 12 is distributed in the receiving device 2 open area of the drum 1. The cutting of waste is carried out simultaneously in two zones: in the main relatively fixed wall 3 with the counter knife 7, and additional relative to the movable wall 4 with the counter fender 8 and the pusher 9. Moving the wall 4 with the hydraulic cylinder 5 is performed Press and feed wood on the knife. The resulting chips through the bottom of the window of the drum 1 enters the augers 10 and 11, which it is transported along the technological flow to the capacity of the transport device. 1 il.

The invention relates to the woodworking industry, in particular to equipment for the processing of wood waste into chips.

The purpose of the invention is to increase the productivity when cutting wood waste and to improve its loading into the receiving device.

The drawing shows the chipper machine, general view.

The chipper consists of a drum 1, a receiving device 2, a fixed counter-pediment wall 3, and a movable counter-vent wall 4 with a drive in the form of a hydraulic cylinder 5, which has a restrictive pressure valve. Receiving device 2 of mine type is mounted on frame 6. On frame 6, fixed wall with counter knife 7 and movable wall 4 with adjustable counter knife 8 and pusher 9 are installed. Fixed screw 10 is installed inside drum 1 and screw 11 is mounted under drum multi-cutter knives 12.

Chipping machine works as follows.

Wood waste, in the form of a bundle, is loaded by a hydraulic manipulator into a receiving device 2 with an open hydraulic cylinder 5 of the counter knife crank 4. Waste falling onto the rotating drum 1 with knives 12 is distributed in the receiving device 2 over the entire open area of the drum 1. When the fallen wood waste is not parallel with respect to the axis of the drum 1, they are compressed by the movable wall 12 and straightened. Felling of manuf.

relative to the fixed wall 3 with the counter-knot 7 and additional relative to the movable wall 4 with the counter-knot 8. With the help of the pusher 9, the operator can distribute the amount of waste in the zones during the cutting process. By moving the movable wall 4 of the hydrocyte with the lindrom 5, the wood is pressed and, accordingly, the wood is fed to the knife. The clamp is adjusted by the pressure of the hydraulic valve in the discharge line of the hydraulic cylinder 5.

The resulting chips are under foot. The windows of the drum 1 are fed into the screws 10 and 11, by which it is transported along the process stream to the vehicle tank.

Non-hardened waste in the additional zone can be transferred to the main zone for the notching at the time of opening the movable counter-breeding wall for the next loading.

Claims (1)

Invention Formula A chipper, containing a drum, a receiving device, a frame, a fixed wall with an anvil, and augers, is designed so that, in order to increase productivity when cutting wood waste and improve their loading into the receiving device, a movable wall is installed on the frame inside the receiving device a drive having a curvilinear surface, with a pusher with an adjustable counter knife fixed on the edge of the latter, and the drive is in the form of a hydraulic cylinder.
