Description

The invention relates to machines for collecting pits on cuttings. It is an improvement of the invention of author. St. No. 950242 and can be used in the forest industry.

The purpose of the invention is to increase productivity.

FIG. 1 shows the proposed machine, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 is a section BB in FIG. 2; in fig. 4 shows a section B-B in FIG. 3

The machine for collecting, cleaning from the ground and transporting of the lower ones includes a self-propelled chassis 1, on which is mounted a hydraulic crane torus 2 with a grip 3. The gearbox 4 is attached to the frame of the self-propelled chassis and the disk rotor 5 is attached to the frame of the self-propelled HiaccH 1 6, which has sliding doors 8 in the lower part of the window 7 and in the rear part. The disk rotor 5 is made of separate adjoining elements in the form of circular sectors 9. The central part of the sectors is connected by the hinge 10 and the rotor axis 11. Rollers 12 are reinforced on the periphery of the sectors. The housing base 13 is provided with protrusions 14 in the form of two-slope slides, with which rollers 12 interact. Projections 14 are freely mixed in a direction, 15 of them fixed on base 13 and equipped with an adjustment device in the form of a screw 16 and nuts 17. The nut 17 rotates freely in the housing of the casing 6 and is limited from axial non-retaining by the ring 18. On the working part of the rotor a flexible coating 19 is fixed, ocnanieHHoe by the teeth 20.

The machine works as follows.

During the movement of the machine through the stubbed punching, stumps are collected by gripper 3 and turning hydraulic manipulator 2 into casing 6. Unclamping grip 3, the stump is dropped onto rotor 5 placed inside casing 6. Folds 8 of casing are closed and form a closed contour. Before the stumps are reset, the rotor 5 is set to rotation by turning on the gearbox 4. During rotation, the circular sectors 9 rest on the rollers 12, which do not move along the base 13 of the casing 6 and meet with the steps 14. The rollers 12 raise and lower on the ledges 14, raise and lower sectors 9, since their hoists are connected with the help of hinges 10 with the axis 11 of the rotor. The protrusions 14 are installed c1K) bod11o in the guides 15 fixed on the base 13. and are equipped with an adjusting device in the form of a screw 16 and a nut 17. Spin the nut 17, cause the projections 14 to move in 11a1file 151, making the lift height change

sectors. Moving the nut 17 along the screw 16 is prevented by the ring 18. The flexible covering 19, equipped with the teeth 20, forms projections in those places where there are 14 projections and takes the lower position in the remaining places. The magnitude of the protrusions on the flexible coating depends on the installation position of the protrusions 14 and can be both the same around the whole circumference and vary either in a certain sequence or in

 random order. Thus, sectors 9 of the rotor create oscillations, the frequency of which depends on the frequency of rotation of the rotor and on the number of projections 14, the amplitude of vibration displacements and the law of oscillations depends on the location of the projections 14. The blunt stump under the action of centrifugal force hits the casing 6. On the rotor chaotic movement of the circumference and experiencing vibro-impacts either constant or variable, depending on the arrangement of the projections 14. During impacts, there is an intense separation of the soil, regardless of its type, since and any ledge is created for this lot is most bligopri spot vibratory amplitude and frequency of oscillation. If there are several snake stumps in the casing with a frequency and a.vibration displacement varying within one revolution of the rotor, this contributes to their greater mixing. Sun group stumps

0 is processed until complete purification. For unloading, the shutters 8 open and stumps fall out through the opening, and the shutters close. The process is repeated. Crushed soil under the action of centrifugal force and vibration moves

5, over the flexible covering 19 and through the windows, is scattered around the grubbing. The flexible coating 19 prevents spillage of soil from entering the space between sectors 9.

The device allows the use of vibration, variable in magnitude even within one revolution of the rotor. The use of such vibration allows to intensify the process of cleaning stumps covered with different types of soil, and makes it possible to treat simultaneously a mixture of stumps with sandy and loamy soil. The duration of the cleaning process in the proposed device is reduced, since

Q processed stumps experience vibrations of greater intensity and are much more frayed. All this makes it possible to increase the productivity of the machine for collecting, cleaning the soil and transporting the machines.
