Abstract

The invention relates to the field of agricultural engineering, in particular, to devices for the dosing of crushed stalked pulp. The purpose of the invention is to reduce the energy intensity of the process, increase the uniformity and quality of the material dosing by leveling the upper layer of the supplied material in accordance with the rate of supply, eliminating spontaneous collapses and pressing the material. In the bunker 1, a feed 2 is installed, leveling 9 and stripping 4 conveyors. The angle of inclination of the leveling 9 and the stripping 4 conveyors is established depending on the angle of repose of the material and the method of its loading. 1 hp f-ly. 1 il.

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to devices for dosing of chopped stalked pulp.

The purpose of the invention is to reduce the energy intensity of the process, increase the uniformity and quality of the material dosing by leveling the upper layer of the supplied material in accordance with the rate of supply, eliminating spontaneous collapses and crushing the material.

The drawing shows the device, General view.

The device for metering the stalked mass contains a bunker 1, in the lower part of which at least two parallel conveyor belts 2 are installed. Each conveying conveyor 2 is separately driven through an anti-roll shaft 3. In the anterior part of the bunker 1, the stripping conveyor A is inclined on its common frame chain-slat type, which strips 5 strips a thin layer of material. The drive shaft 6 has the ability to move in the guides 7 relative to the drive shaft 8. This offset allows the use of a device for uniform dosing of different materials, each of which has its own angle of repose. The drive shaft 8 of the scrubbing conveyor is installed above and moved forward relative to the feed conveyors 2, which excludes pressing of the dosing material.

On the frame of the bunker 1 above the feeding conveyors 2 there is an inclined leveling conveyor 9 of a chain-slat type, which strips 10 extend the surface of the supplied material and can move along the guides 11 relative to its drive shaft 12. This allows adjusting the position of the leveling conveyor 9 in according to the average line of the roughness of the surface of the supplied material. The direction of movement of the conveyors is indicated by arrows.

The device works as follows.

JV angle of inclination and leveling conveyors. Depending on the amount of supply of the dosed material, the speed of the feeding conveyors 2 is set, and the speed of movement of the combing conveyor 4 also changes accordingly, since the drive of the feeding conveyors 2 and the combing conveyor 4 is driven from the shaft of the counterdrive 3.

Depending on the amount of material dispensed, hopper 1 is periodically filled during continuous unloading and serves to receive and accumulate material.

The discharged material into the hopper 1 by the feeding conveyors 2 is moved along the bottom to the leveling conveyor 9. With the slats 10 of this conveyor, the upper surface of the applied mass is leveled by removing the ridges and filling the material of the cavities removed from the ridges. Further, the material with a flattened surface is fed to the combing conveyor 4, which removes a certain layer from the entire thickness of the feed material with the slats 5. As a result, the material is fed in a uniform flow. In addition, if the material constitutes a mixture of a component (for example, grain, straw particles, spikelets, and chaff) with different physicomechanical properties, then as a result of the loading of the hopper 1 and the movement of the ma-. The rial feed conveyor 2 segregates it. As a result, the proportion of its components remains constant. Installing the stripping conveyor 4 at an angle of repose of the material eliminates its spontaneous collapses, and moving the lower part forward relative to the feeding conveyors 2 prevents the material from being pressed in during the dispensing process.

If the chain of one of the feeding conveyors 2 breaks, to release the hopper 1 from the main part of the material it is necessary to disconnect it from the counter-drive shaft (remove the chain), and the other feeding conveyor 2 to release the hopper 1 without using manual labor.

Claims (2)

1. Device for dosing feed stalked mass containing 1 The bunker, the bottom of which is made in the form of a feeding conveyor, and a stripping conveyor installed above the feeding conveyor, are somewhat different because, in order to reduce the energy intensity of the process, improve the uniformity and quality of dosing by leveling the upper layer of the supplied material in accordance with the feeding rate , excluding spontaneous collapses and compressing the material, it is equipped with a leveling conveyor, which is installed obliquely in the upper part of the bunker, the driving shaft 606 conveyor belt is placed in front of the feed conveyor, while aligning and wiping conveyors mounted on the frame of the bunker with the ability to move in the longitudinal-vertical plane relative to its drive shafts. 2. The device according to claim 1, about t l and so that, with the aim improvement of working conditions by emptying the bunker when one of the feeding conveyors breaks; at least two feeding conveyors with separate drive are installed in the bunker.
