Abstract

The innovation relates to a stationary mechanism which, with a reel rotating periodically without a shift mechanism, makes an outside-of-reel-placed support's (s) forward-backward move with relatively large impellent power in a practically limitless span, using the side-play of the drive chains (belts) and placing at least two stars (trundles), the respective drive and propulsive stars (trundles), vertical pivots slightly overlapping and leaning into each other - under an angle of 3-10 degrees depending upon the type of drive chains (belts), fig. 1 shows the proposed mechanism with one support axonometric functional layout. The innovation can be used in wood chip and sliver distribution devices from the warehouse to the processing room as well as in scientific labs and for other needs.<IMAGE>

Description

Description of the Invention Push-puller

The invention relates to a drive mechanism for smoothly dispensing wood chips and chips from storage by installing reciprocating rakes (stokers) under their piles.

There are known mechanisms for dispensing woodchips or chips from warehouses, such as:

1) Threaded or screw conveyors / 1 /

2) self-propelled bridge cranes or polyp 121,

(3) bucket or electric forklift trucks, bulldozers,

4) foreign hydraulically powered stokers / 3,4 /.

Threaded conveyors are not performing well because of difficulty in moving under piles, moving in a bucket and breaking. Bridge cranes with grabs or polyps work satisfactorily but do not use warehouse space due to bulky conditions. Their construction is expensive. Forklifts and bulldozers can only work outdoors. It is uneconomical to operate them 24 hours a day. Due to the wood dust, electric forklifts can only work outdoors. The operation of hydraulically operated forklifts is costly as the warehouse floor level should not differ by more than 0.1 cm, which makes construction more expensive. The unit does not have a power limiter.

This mechanism of the invention may have a warehouse floor

1-2 cm level difference and its operation is significantly cheaper.

The object of the invention is to provide the economy with a relatively inexpensive, economical, easy-to-make and operational reciprocating stationary chip or chip feeding mechanism from warehouses characterized by a relatively high propulsion power.

The proposed mechanism can operate both obliquely and vertically as well as various other needs with one or two calipers.

SUMMARY OF THE INVENTION: The present invention provides a slider-traction design consisting of a metal frame-mounted, periodically rotating roller having a series of spindles with star (or rollers) and drive chains (or drive belts) that pull at least one caliper outside the roller, and characterized in that the vertical axes of non-driven drive sprockets (or drive belts) are slightly interchanged with respect to the vertical axes of the drive sprockets (or rollers) and at an angle of 3-10 ° depending on the drive chains (or drive belt). The solution described in brackets is for low power trucks, such as a lab, etc. needs.

The operation of the proposed slider-traction unit is illustrated in the axiometric diagram (Fig. 1). The drive shaft (1) is fitted with an asterisk (2) and an independent rolling roller (3) with two shafts (4 and 5). The drive shaft is (4) and the drive shaft (5) is slightly inclined and movable, which have a sprocket (7 and 8) on the brackets outside the roller (3). The vertical axes of the asterisks (7 and 8) do not coincide and stand slightly alternately with each other, which is also allowed by normative documents.

Outside the roller (3), driven by the rollers and the plain bearing (17), a movable caliper (9) is grooved around the perimeter by an endless drive chain (10) surrounded by a sprocket (7 and 8) and forms an endless loop (Figs. 2 and 3). , using a sidewall of the drive chain (10).

Turning the shaft (1) drives the asterisk (2), the shaft (4) and the sprockets (7 and 8). The caliper (9) moves to the end of the phase, the roller (3) is released from the brake (11), rotates 180 ° (figs. 2 and 3) and the caliper (9) begins to retract.

The actuator of the sliding-towing structure consists of an electric motor, a high gearbox, sprockets and a drive chain which drives (Fig. 5) a shaft (1) supported on a metal frame by bearings. Asterisk (s) (Fig. 7) (2) mounted on the shaft (1) and an independent rolling roller (3), which (Fig. 4) is enclosed by welded angles, which in turn are supported by welded narrow sheet metal tracks. rollers (21) and belt brake (11), which must be sanded or rolled after welding. The force limiter fingers (22) are located on the shaft (1).

4 trusses (13) welded (Fig. 6) in a roller (3), consisting of angle irons with bearing housings and movable platform (s) (14) with axle (s) (15) and adjustable (-) (s) the coupling (s) (16). The bearings (20) have a shaft (s) (4) with an asterisk (6) on the bearings (fig. 7) and a star (s) (7) on the bracket (s) outside the roller (3). Free-standing star (s) (8) mounted on movable platform (14). The asterisk (7) and (8) have barrel-like teeth. The sprocket (8) is adjusted slightly alternately with the sprocket (7) with a vertical axis deviation of 3-10 ° depending on the type of drive chain. The sprockets (2) and (6) are connected to the drive chain (s).

A caliper (9) is mounted on the shaft (1) and has a sliding bearing (17) in the middle of the cut-out (Fig. 1). The rounded ends of the caliper (9) are a hot-wound U-shaped profile with a grooved narrow metal sheet. In order to increase the contact surface of the drive chain (10) which surrounds the caliper (9), small plates (18) are welded across (Fig. 8B) that fit into the side profile of the drive chain (10) or the corresponding sprocket teeth . The caliper (s) (9) is surrounded by an endless drive chain (figs. 1, 2, 3) which encircles the asterisks (7) and (8) and forms a loop. As a result, the rotor (7) and (8) turn the caliper (9) into alignment. Connect the drive chain (1)) with riveting and tighten with star (s) (8). The caliper (s) (9) is guided by a sliding bearing (17) and rollers, wherein (4) 4 rollers (19) (alternatively 8 rollers) are provided with welded conical discs for adjusting the direction of the drive chain (10) in the groove. (s). The whole structure is placed in a strong frame, which is fixed to the foundation with bolts.
