Description

(54) BUNKER DEVICE

one

The invention relates to devices for transporting and dispensing concrete and mortar mixes and can be used in all industries.

A bunker device is known, comprising a chute housing and a bolt, consisting of two sectors hinged on the walls of the chute, levers, one ends of which are connected to sector hinges, and in others grooves and pins are formed to interact with the slots of the levers 1.

However, the known bunker device is unreliable in operation due to the lack of synchronism in the operation of its sectors.

The aim of the invention is to increase the reliability of the device in operation by ensuring the synchronous operation of its sectors.

The goal is achieved by the fact that a bunker device comprising a chute body and a gate consisting of two sectors hinged on the chute walls, levers, one ends of which are connected to sector hinges, and others are formed with grooves and pins for interacting with lever grooves, equipped with guides fixed to the wall of the chute and located in them with the possibility

movement of the bar, while the pins are mounted on the last.

In addition, the device is equipped with rollers, mounted on the ends of the strap.

FIG. I shows the bunker device (shutter closed); in fig. 2 - shutter in the open position; in fig. 3 - driven lever at the beginning of the opening of the shutter; in fig. 4 - driving lever; in fig. 5 shows an embodiment of a rod with rollers;

10 in FIG. 6 - rollers in guides.

The bunker device consists of a body 1 with racks 2 and a chute 3 fixed to the body 1. Between the racks 2 are mounted on hinges 4 two sectors 5

15 shutter.

The single-arm drive 7 and the follower 8 levers are rigidly fixed to the wasps 6 of the hinges 4, at the ends of which there are identical grooves 9. In the vertical plane 20 between the hinges 4 are installed in the guides 10 of the bar II. The guides 10 are rigidly fixed to the walls of the chute 3.

Pins 12 fixed inside identical grooves 9 are rigidly fixed to the rods. A hinge 13 is fixed to the hinges 4 of the leading sector 5. Alternatively, the rods can be made with rollers 14. The diameter of the rollers d is less than the distance t between the guides. In the case of stationary implementation of the bunker device, the handle 13 is connected to the rods by means of a hydraulic or pneumatic cylinder. The bunker works as follows. Turning the handle in arrow A, the driving levers 7, rigidly mounted on the driving sector 6 of the driving sector, also rotate around the hinges 4 and lift them 12. Since the pins 12 are fixed on the slats 11 installed in the vertical guides 10, they move in a vertical plane. Climbing up, the pins 12 carry the driven levers 8. The pins 12 move in the slots 9 of the leading 7 and the driven 8 levers. The forces FI of the driven arms and the FS of the driving arms are equal and always directed at the same angles with respect to the arms. Consequently, the torques MI and Mg, under the influence of which

(And the sectors rotate are independently equal to the sector angles. Synchronism in the sectors ensures high shutter reliability. Claims Bunker device comprising a chute body and a gate consisting of two sectors hinged on the chutes sectors, levers, one ends of which are connected with sectors hinges, and in others grooves and pins are formed to interact with the grooves of the levers, characterized in that, in order to increase reliability in operation by ensuring synchronous operation of the gate sectors, it is equipped with replennymi heat to the wall of the guide and is located therein with "POSSIBILITY moving strip, the pins are fixed to the latter, 2. The apparatus of claim. 1, characterized 2. A device according to claim 1, characterized in that it is provided with rollers mounted on the ends of the bar.
