IN) About

The invention relates to equipment for grinding by technology chips made of wooden containers unsuitable for further use. The purpose of the invention is to simplify the design, reduce energy consumption and overall dimensions by increasing the specific function of the measuring body of the machine.

The drawing shows a drum chipper machine, a longitudinal section.

The drum chipper for chopping wood waste includes a housing 1 with an inlet opening 2 in the upper part and a discharge opening 3 in its upper part. Inside the housing 1 on the drive shaft there is a drum 4 with chopping elements in the form of knives 5 ( incisors, beat, bullets, etc.). On the housing 1, the opposite of the blade drum 4 is fixedly fixed to the counter-knife 6, installed with a gap a equal to 0.5-1.0 mm, relative to the knives 5. In the place of abutment of the loading neck 2 to the housing 1 an additional counter-knife 7 fixed with a gap A, equal to 150-200 mm (A a), with respect to skin 5, with the wall 8 of the housing 1 between the counter-knife 6 and the additional counter-arm 7 being convex, forming the chamber .9 for the pre-ground material,

The drum chipper for shredding waste works as follows,

Wood waste, which is mainly unsuitable for further use, is subject to pulverizing through the loading neck 2. is fed inside the body 1 to the rotary drum 4, which interacts with the knives 59 attached to it and is pulled in the gap A between the blades 5 and the additional: anvil knife 7, forming the pre-grinding chamber 9. Gap. The magnitude is comparable to the elements of the structure of the ground stumps, the latter are easily crushed in the pre-grinding chamber 9 into smaller elements that do not have a regular spatial structure. Elements of pre-collection, waste wood are released into the chamber

9 of the pre-ground material formed by the convex wall 8 of the housing 1. The volume of the pre-grinding chamber 9 is selected from the condition of filling it with pre-crushing elements of wooden boxes without forming jams and free flow of these elements from the pre-grinding chamber 9 to mounted with a small gap and the counter-knife 6 and the knives 5 rotating drum 4. Forming as a result of grinding chips through the discharge opening 3 removed TC from the housing 1.

Preliminary crushing of trees into smaller elements with violation of the regular spatial structure of the crushed material increases the intensity and improves the uniformity of the supply of the crushed material to the cutting area, eliminating the slipping of the boxes before their grinding. This increases the intensity of the processing of wood containers on process chips with simultaneous smoothing of peak loads on the drive of the shredder, which increases the productivity of the process.

Combining the elements of preliminary and final grinding of wood waste in one unit increases its specific functioning, simplifies the design of the shredder, reduces its energy consumption, and reduces the size.

Invention Formula A drum chipper for shredding wood waste, including a housing with an adjacent feed neck and a discharge opening, mounted inside the housing a drum mounted on the drive shaft with grinding elements and oppositely fixed chopping have been with so that with. in order to simplify the design, reduce energy consumption and size by increasing the specific functioning of the grinding bodies of the machine, it is equipped with an additional counter-knife fixed in place of the loading neck to the body, while the gap between the grinding elements of the drum and additional 31437230. The main anvil is made of a large material formed by the wall of the body above the gap between the anvil and the grinding table between the main and additional drum components, and the chambers, which are cut out, for the pre-crushed and grinding elements of the drum.
