Description

The invention relates to forestry and wood industries and can be used for sbrosku logs, boards, planks with a longitudinal conveyor to the accumulator ⁵ at their sorbitan tran sportation.

Known dumper piece goods, which includes the frame, T-shaped pusher and drive [1]. . θ

The disadvantage of this ejector zak- ^and becomes active in the fact that the non-parallel with respect to cargo ™ colliding beams possible destruction of the attachment of the pusher or pusher jamming due to the emergence dinamy- 15 iCal loads.

The closest to the invention to the technical essence and the achieved result is a dumper group-20 calls, comprising a housing, a slide on which the pusher of horizontal action with a pushing beam is pivotally fixed, and the drive [2].

The pusher of such a resetter is made in the form of a straight rod. The disadvantage of this device lies in the fact that when dropping loads, there are significant dynamic load forces, and when throwing lengthy ones; thirty

cargo you need to install two ejector.

The purpose of the invention is to reduce the dynamic loads and the alignment of the cargo when it is non-parallel with the rig position.

The goal is achieved by the fact that the pusher is made in the form of elastic plates parallel to each other with stops, which are located on the inner surfaces of the plates opposite each other, and the plates and hinges of their fastening are located in different vertical planes.

In FIG. 1 shows the proposed cargo dumper, top view; Fig 2 - the same, side view (in section); Fig 3 is a view along arrow A in Fig. 2.

The load release device includes a housing 1 with guide rods 2, on which a linkage 3 is installed. On the link 3, a pusher of horizontal action is fixed pivotally in the vertical and horizontal planes, which is made in the form of elastic plates parallel to each other or sets of plates: right 4 and left 5 with stops 6, located on the inner surfaces of the plates. Plates 4 and 5

the pusher and their hinges 7 and 8 are located in different vertical planes. At the end of the pusher is pivotally fixed pusher beam 9.

In the ejector body 1, a drive chain gear 10 is located that performs the function of a gearbox and includes -4 driving sprocket ON mounted on the shaft of electric motor 12, and driven sprocket 13, and traction chain transfer 14, bending around driving sprocket 15 and driven sprocket 16 Chain gears 10 and 14 are located in different planes. The driven sprocket 13 of the drive chain transmission 10 and the leading sprocket 15 of the traction drive 14 are fixed on the same shaft. The curtain is attached to the upper branch of the traction gear 14 with a protrusion 1 7. ΐ

For tensioning the chain gears 10 and 14, tensioning devices 18 I 19 are mounted, mounted on leaf springs in the form of springs 20, supported on stops 21. Springs 20 are preloaded with nuts 22 tension devices 18 and 19. In the initial position of the backstage 3, a latch 23 is installed , and at the end of the course of the scenes - shock absorbers 24 and 25. To turn on the electric motor 12. serves as the sensor 26.

The dumper works as follows.

Moving in the direction indicated by the arrow, the load 27 presses the lever of the sensor 26, which turns on the electric motor 12. In turn, the electric motor 12 rotates the driven sprocket using drive chain transmission 10, which informs the movement of the pull chain 14 with the link 3. In this case the plates 4 and 5, hinged on the link 3, carry out translational motion in the direction of discharge of the load 27 and push it with the beam '9 into the hopper.

At the end of the stroke, the rocker 3 acts on the track switch, which switches the electric motor 12 to reverse rotation and idling the scenes 3. At the end of the idling of the scenes 3, the track switch is also installed, which deactivates the electric motor 12. At the same time in the initial position, the link 3 is locked with a lock 2 3.

When pushing the load 27 in the direction of the arrow, the plunger deviates from the axis of the resetter by an angle β.

With a rolling load of 27, the pusher can simultaneously rotate upwards. With a non-parallel load, 27 is a collision beam 9, when the log lies at a distance of. from the front end and at a distance b from the rear end of the colliding beam, the impact is perceived by the rear end of the colliding beam; there is a bending moment. Since the hinges 7 and 8 and the plate 4 are located in different vertical planes, the compression of the plate 4 occurs. The latter bends slightly and absorbs. During the deflection of the plate 4, the stops 6 approach each other and the second plate 5 is put into operation in the elastic system, providing additional resistance to the total bending of the plates 4 and 5 and further deflection. pushes the beam 9 from the initial position. After the cargo (log) 27 rebounds from the rear end of the beam 9, plates 4 and 5 return the beam. 9 to the original position and then the log, which occupied the parallel position relative to the beam 9, collides into the drive.

Making the pusher from resilient plates with stops eliminates breakage in the mount of the colliding beam and the pusher itself, reduces dynamic loads and allows leveling the load with its non-parallel ™.
