Description

Patent No. 19341 describes a crushing machine, in which the trimmed logs pass through an annular frame equipped with arms that are hinged to it with bark-cutting tools, springs pressed to the center of the frame, and the logs are fed into the frame with cross conveyor crossbars.

In before; instead of one annular cutter frame, two are applied with the machine modification of the machine, and the levers associated with them are provided with spring-loaded buffers installed in the common fixed ring frame at their free ends. For the direction of the rounds to be machined, a device consisting of a number of bars, each hingedly connected to these frames, is used for each cutting frame. For the purpose of feeding the rounds, in addition to the chain conveyor, feed rollers are used, the lower of which receives rotation from the toothed chain conveyor, and the upper one is pushing.

The feed of rounds to the chain conveyor is carried out by means of an inclined plane in the form of a table, the inclination of which can be changed, and fixed stops to hold the fed rounds into. proper position.

In FIG. 1 shows a horizontal section along the length of the machine frame; FIG. 2-part cutter holder; Fig longitudinal section of the machine; FIG. 4-section along the lines of VG in FIG. 3; FIG. 5 is a section along line E in FIG. 3; FIG. 6, 8- details.

A frame 4 is attached to the frame / machine frame (Fig. 1), adjacent to which is an inclined plane in the form of a hundred, aa 3, designed to feed a round nod onto a chain conveyor and that can change its inclination due to the hinged connection 5 (Fig. 4) and the presence of the sliding leg 6, hinged to the table 3 and held in that and another position by means of the movable curved bar 8. On the frame 4 there are several “fixed 9 stops”

to keep the round plate fed to the conveyor in the proper position.

In order to preserve the direction of round-off diving, stops / 7 (Fig. 3) are applied, fixed in the lateral slots 12 on the Gall 1.3 chain, moved by gear gears 14.

In addition to the chain conveyor, feed rollers 16 are used for feeding rounds, the lower of which receives rotation from the gear of the chain conveyor, and the upper one is pushing and moves up and down along the toothed rack 18, depending on the diameter of the round 9, mounted on the shaft 2G-. A block 27 is seated on the latter, through which the rope with the weight necessary for pressing the upper feed roller 16 passes from the tab 22 in the frame 7.

On the shaft 23 of the lower feed roller / 6, a gear 24 is attached, coupled with a gear 25 for driving the Gall chain around the wheels 14 and having the same skbrost with the speed of the feed rollers / d.

A gear 26 is mounted on the shaft 23 to actuate the material to be transported by the apparatus to be ignited; the gear 26 is rotated from the pulley 28. The latter is tightly fixed on the shaft 29 (Fig. 4) and has a pulley 30 with a free stroke.

Instead of one annular incisal frame in the proposed modification of the machine, two such frames 33 (Figs. 1, 3, 5 and 7) and the levers 44 associated with them, pivotally supporting cutters 31, 32. (Fig. 8) and fitted at free ends are used. spring buffers 46, 47, installed in a common fixed ring frame 48 (Fig. 6).

For the direction of machined rounds, on each cutting frame 33 there is a series of bars 38 connected to these frames by a hinge: on the one hand, by means of earrings 36, and on the other, by means of spring buffers 39, 41 (Fig. 3).

The levers (holders) 44 supporting the cutting cutters 31, 32 are at the end} {ears and are connected at one end with an eye 45 attached to the annular incisal frame 33, and the other with a spindle 46 with a spring 47 mounted on it. (Fig. 5). The indicated spring holders are placed in a common fixed annular frame 48, for adjusting the springs on. The upper part of the holders is placed the adjusting screw 49 with the lock nut 50.

The holder 44 has in the upper part of the slot for the cutter 57, 32-step 57 (Fig. 2), through which the locking screw 52 is passed, pressing the insert 53 and in which; in turn, the upper part of the tool rests. The cutter at the location of the fastening screw 54 is provided with a slot 55. The screw 54 presses the plate 56 with a recess for the screw head.

The incisors with the derla tors act automatically, irrespective of the curvature of the rounds. When moving the last incisors, they will remove the bark on the adjusted thickness, i.e. produce debarking or shavings.

The work of the proposed crushing machine proceeds as follows. The round bar is to be laid by the workers on an inclined table 5, from which he, by means of his own weight, moves automatically to the bottom of the table, into a tray under fixed stops P. From the table 3 yriopOM 77, he moves between the feed rollers 75 pushing him forward , whereby the cutters .57, 52 produce debarking or shavings of the material.

On exiting the rollers 75, the circle is advanced further by pressing the next round, and thus the work of debarking will proceed without interruption. At the end of the debarking round the ke goes into the directions of the tray (not shown on the bottom), from which the peeling rounds are sorted and cleaned into a stack.

When the machine is in operation, a large amount of bark or chips will be produced. So that it does not impede work, a worker is put in to remove the bark from the machine.

- In order for the bark, cut by the upper incisors, not to fall on the machine, they are made oblique; Thus, the chips go to the sides, and at the outlet openings of the holders 44 for it there are visors of such a shape, due to which the chips are finally thrown out of the machine.

(not shown). In addition, on the protective shields of the spring nests, you propose to build a cone-shaped casing made of sheet iron, so that the chips, which are not moved away from the machine by a slanted cutter and visor, will go to the side of the holder along the marked cone.

The subject matter of the invention.

1. Change of the crushing machine, described in patent number 19341, from | Owing to the fact that instead of a single annular incisal frame, two such frames 55 (Fig.) were used, and the supporting incisors J / 52 associated with them were provided with levers on the free ends of spring-loaded buffers 46,47 installed in a common fixed annular paivje 48 .

2. In the machine tool described in paragraph 1, a device for directing the machined rounds, which is used for each cutting frame of a row of 38 Russian (Fig. 2.3) connected to these frames is hinged: from one side-using earrings 55, and on the other, through spring buffers.

3. In the machine described in paragraph 1, the use for feeding rounds in addition to the Chain conveyor also includes feed rollers / j (Fig. 1, 2), the lower of which receives rotation from the toothed chain conveyor and the upper one is push.

4. With the use of the machine for feeding rounds to a chain conveyor of an inclined plane in the form of a table 5 (Fig. 1, 3), the inclination of which can be changed, and fixed stops 9 to keep the round table fed to the conveyor in the proper position
