REMOVABLE HOPPER OF DISTRIBUTOR OF BULK MATERIALS

The utility model relates to the content of the roadway in winter.

A common drawback of bunkers with bulk materials and in particular bunkers operating at low temperatures is the freezing of bulk materials on the walls of the bunker. This disadvantage is largely eliminated by installing vibrators on hoppers.

A known spreader of bulk materials (see USSR author's certificate J4o 1344847. M. cl. E 01 C 19/40), in which an unbalanced type vibrator is installed under the bottom of the hopper.

The disadvantage of this spreader is the need to install a powerful vibrator due to the huge mass of the hopper with bulk material, as well as the complexity of changing the amplitude of the oscillations when the mass of bulk materials changes as they are unloaded.

For uniform unloading of bulk materials, belt or scraper conveyors are installed in the bunkers, over which, to reduce the load, a gable (wedge) divider is installed, which, by reducing the load on the conveyor, significantly contributes to the freezing of bulk materials.

..ri

individual sections movable relative to each other, either fixed on a common longitudinal axis (see USSR author's certificate No. 783397), or suspended on chains attached to the hopper safety grill (see USSR author's certificate No. 1609914).

The drawback of such hoppers of bulk materials distributors, in which the movable sections of the gable dividers must vibrate under the action of the material mixed by the conveyor branch, is the structural complexity and possible termination of the oscillations of the gable sections with a decrease in the layer of bulk material, which will contribute to the freezing of bulk materials over the gaps of each longitudinal walls of the bunker and a gable divider.

The purpose of the proposed hopper of the distributor of bulk materials is to simplify the design, increase reliability, as well as compliance with the conditions of uniform spreading of materials,

In a removable hopper of a bulk material distributor installed in a car body, comprising an unbalanced vibrator, a scraper conveyor, a gable divider, a slide gate, a disk spreader, the goal is achieved in that the vibrator is mounted in the plane of longitudinal symmetry of the hopper on the rear transverse wall of the hopper, with which it is rigidly a continuous longitudinal gable divider is connected.

In FIG. 1 schematically shows a spreader of bulk materials.

In FIG. 2 shows a top view of the dispenser hopper.

In FIG. 3 shows a cross section of a hopper of a bulk material distributor.

The removable hopper of the distributor of bulk materials consists of a removable tank 2 installed in the body / car with longitudinal 3 and transverse front 4 and rear 5 sides, on the bottom 6 of which a scraper conveyor 7 is mounted, a. in its rear part, under the shutter-plate shutter 8, there is a discus thrower 9. Above the feed conveyor 7 on

. .:.-3

brackets (legs) 10, flat in the vertical plane, a continuous gable divider / 7 is fixed, rigidly connected to the front side 4, on the outside of which in the plane of symmetry of the tank 2 an unbalanced vibrator J2 is fixed. After installing in any way capacity 2 in the body / vehicle and connecting the vibrator / D drives of the scraper conveyor 7 and the disc thrower to the vehicle hydraulic system, the bulk material dispenser is ready for operation.

The material poured through the safety grill (not shown in the drawings) into the container is conveyed by the conveyor 7 to the disc thrower 9 and then is evenly scattered when the vehicle is moving onto the carriageway. The thickness of the material layer is controlled by a slide gate. The double-slope divider // serves as a support for bulk material and divides the tank 2 but horizontally into two zones. The pressure in the lower zone is determined only by the weight of the material under the divider P on the conveyor 7.

Thus, the conveyor / does not work under the rubble, its power consumption is reduced, and the reliability of the work is increased.

Since the front side (wall) 4 above the conveyor 7 is not connected to the bottom of the tank 2, it can be considered as a beam pinched at the ends (on the longitudinal J walls of the tank). Moreover, the amplitude of the vibration of the middle part of the front side 4 and the divider connected to it // under the action of even a weak vibrator is quite large in comparison with the amplitude of the vibration of the longitudinal walls 3.

The mobility of the divider // relative to the walls 3 of the tank 2 during operation of the vibrator 12 is more effective to prevent freezing (arching) of dry material than the coordinated vibration of the entire body of the tank 2 under the action of a powerful vibrator.

The use of the proposed removable hopper of bulk materials can improve the uniformity of the spreading of bulk material without prior separation.
