Description

Instruments for measuring round logs in cubic meters, equipped with sliding bodies coupled to the recording device, are known, as is the use of friction wheels in the recording instruments for imparting an appropriate rotation speed to the rev counter. In the proposed device for measuring roundwood in cubic meters, the sliding bodies are made in the form of a spring and are articulated by means of toothed racks with rotating 1c drums on which the ends of the cable carrying the block are fixed. This block is connected by a chain with gears under tension of the load in order to move the last gear racks with friction wheels to transfer the corresponding speed to the rev counter while rotating the friction wheels on the vertical and horizontal disks designed to rotate under the action of an electric motor interlocked with the engine scruffy wood

In FIG. 1 shows a vertical section of a part of the plant, with the proposed device installed in it; FIG. 2 is the same side view; FIG. 3 - the same, top view.

Asynchronous motor (not shown in the drawing) rotates the chain 27 forest trays

(194)

(Fig. 1) at a uniform speed and delivers the logs 28 from the water basin to the factory building. The speed of an asynchronous motor can vary only within small limits depending on the load. On the path of the hamper 27, there are bent springs / serving to measure the diameter of the walking log. The semicircular shape of the springs 7 is taken so that the log can smoothly part them and also smoothly reduce them. Springs /, flow through the passage of logs through them, move gear racks 2, turning gears 5 (Fig. 2). The latter are connected by a key with an axis 3. From the movement of the rails 2, the axis 3 rotates and rotates the drums 4. The flexible steel cable 6, thrown over the block 7, is connected to the drums 4 by the ends. When the drum 4 is turned, the cable 6 will unfold from it; load 22, through the gear system, will pull the cable b. If the log through the springs is not strictly centered, then one spring / will move more than the other, and different slack ends of the cable 6 will be obtained. To eliminate this undesirable phenomenon, block 7 is installed. From block 7 to load 22, through a chain sprocket 70, parasitic 27 and a 10 W chain gear (second degrees), again through gear 27 to load 22

protruding chain 20. With the passage of the log springs 7, a weak end of the cable 6 is obtained, which through block 7 and chain 20 allows the weight 22 to be lowered. If the logs come off the springs 1, then the cable 6 will be pulled up and thereby lift the load 22.

A small electric motor 18, through a reducer (not in the drawing), vrah, drives 168 (vertical). On the disk 16 b plane, touching its rubber shank, the wheel 13c can move along the axis 15 v; it is associated with an axis 15 in a key 14s laid along the entire axis. The wheel 13 is moved by a fork 12, its skins being in sliding contact with the driving disk 31 of the wheel 138. The fork 12 is connected to the rail 11, which can receive movement either up or down from the jaws of Y. The latter sits on the same axis 8 with gear Yua chain transmission. When lowering the load 22, the chain 20 rotates the chain gear 10; the latter transmits motion to gear 9, which by its rotation will lower or raise the rake 11 in. This rake moves the plug 12c, and this one, for the drive disk 31 of the wheel 13b, moves the wheel 13b from the center to the periphery of the disk 16c. The disk 16c rotates continuously from the electric motor 18. If the wheel 13c is in the center, it will not rotate - this corresponds to the springs collapsed. As soon as log 28 causes the springs 7 to disperse, the wheel 13c will move from the center of the disc 76s to the periphery, by an amount proportional to the diameter of the log. The speed of the wheel 13c will vary depending on its position on the disk 16c. In the center of the disk, its speed will be equal to O, and at the periphery it will have a maximum value. Consequently, a certain disk speed 13c will correspond to a certain diameter of the log, i.e. the speed will be directly proportional to the radius of the log. But since square dependence is necessary for determining the volume of a log, in addition to the vertical disk, a horizontal disk 7bg is also inserted, and the entire device of the vertical direction is repeated in the horizontal direction. Horizontal

the device differs from the vertical only in the absence of a 16g disk. Instead, the gear 23 is set, connected tightly with the axis of 75g.

The instrument will work in the following order. Lesotaska idling, there are no logs on it. When the induction motor turning the logging station is turned on, the electric motor 18 interlocked with it turns on. When the motor of the trailing motor is turned off, the electric motor 18 is also turned off; during the operation of the latter, the disk 16c rotates through the reducer. The rotation speed of this disc should be in the order of one or two revolutions per minute and strictly constant. Since there are no logs at logging, the springs 7 are one hundred tons reduced. All parts of the device stand with the exception of the electric motor 18, the gearbox and the disk 1b8. When the forest truck begins to haul logs, they pass through the springs 7, which measure the diameter of the walking log, and through the cable 6 slack, proportional to the diameter of the log, is transmitted to the rail 77b; the latter sets in motion the fork 728 and for the disk leash 31 of the wheel 13b moves the latter in proportion to the diameter of the log at the logging chamber, closer to the periphery of the disk. The wheel of 13th, rotating at a speed proportional to the diameter of the log, will rotate the axis 15c. At the end of the axis 15b there is a 7bg disk, equal in size to the 1b8 disk. Therefore, the disk 16b will have a speed proportional to the diameter of the walking log. The longer the log, the longer the instrument will be in operation. The time during which the log passes the springs 7 will be proportional to its length.

To get the speed proportional to the volume of the log, a device of the second degree is introduced.

When lowering the load 22 at the same time with the rail 77c, rising upwards by the same amount, the rail 77g (horizontal) will move to the right from the latter.

The chain and gear gears 9 and 10 of the first and second degrees are equal in diameter. The wheel 13g moves along the surface of the disk 76 at the same time as the wheel 13c, which moves along the surface of the disk 1b8. The wheel 13g will develop a speed proportional to the square of the radius of the log. With the same speed, the 75g axis will rotate gear 23; The latter is mechanically connected to gear 24, which rotates the axis 25 and actuates the counter 26. The indicated counter will show the size of the forest covered in a given period of time in cubic meters.

The subject matter of the invention.
