Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The invention relates to the feeding of free-flowing materials in animal feed conveyor systems for feedlots, especially of the type with channel or closed tube conveyor elements. It relates to a device for.

The device is applicable, but not exclusively, to granular or powdered animal feed conveying systems of the type characterized by a conveyor rope from which conveyor elements spaced apart from each other project, said rope having a closed annular shape. It is controlled to move in a circuit in a tube or groove.

Feed is transferred from the container traversed by the tube and discharged into the feeding pan through spaced openings in said tube, each provided with a shutter or similar closure means.

Systems of the aforementioned type are well known to those skilled in the art and will not be described further here.

PROBLEM SOLVED BY THE INVENTION By properly supplying feed from a storage container to the inside of the pipes of a conveyor system, the technical problem is successfully solved.

First of all, feed should not be fed inside the tube if the amount of feed is too high or too low. This means, for example, that the feed supply is stopped due to a blockage in the tube, or that the feed is not fed sufficiently or evenly into the feeding pan (often caused by the phenomenon of "bridging" of feed inside the storage container). ).

In other words, the feeding device should be equipped with a conveyor system that always supplies a uniform amount of feed.

Another requirement of this type of equipment is the removal of foreign substances that are always present in the animal feed and which, if ingested, can harm the animals and also destroy the conveyor ropes and guides.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a means for overcoming the above-mentioned problems through a coaxial opening in the wall of the container, on the outside of the container coaxially with said auger and above the groove in which the flexible conveyor element moves. a hopper cam container with a rotating auger conveyor disposed at the bottom adapted to convey the contents of the container into a rotating drum-shaped screen located in a The ejection of material and also the ejection of foreign matter outside the groove is carried out by a feeding device whose rotational speed of said auger is synchronized with the forward speed of the flexible conveyor element.

If a rope with a radially projecting disk-shaped member is used as a conveyor element, rotation of the auger/screen structure will cause said disk supporting rope, e.g. This is done by attaching it to.

Of course, an independent motor may be provided for rotating the structure, but in this case the motor is preferably synchronized with the forward speed of the flexible conveyor element.

The rotating drum is cylindrical in shape and has internal helical ribs to expel foreign matter. However, the preferred form of the embodiment has a conical shape with the largest diameter near the forward end where the foreign matter is expelled.

The device according to the invention solves all the problems that arise when supplying the desired and correct amount of granular or powdered material with a conveyor system having flexible elements moving in a guide.

As a result of the synchronized movement of the auger and the flexible conveyor element, the discharge of material from the hopper container by the auger is commensurate with the amount of material conveyed by the conveyor element.

(So, if we first determine that the material throughput of the auger (which depends on the pitch of the auger flights) is less than, or at most the same as, the throughput of the flexible conveyor element, then self-adjustment takes place.

Problems of clogging of the guides along which the conveyor elements move do not occur and such elements are not subject to overloading. Furthermore, there is no risk of damage from foreign objects such as iron. This is because the sieving action of the rotating screen removes foreign matter from the useful material.

Embodiments of the device according to the invention will be explained in more detail with reference to the accompanying drawings, in which: FIG.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The apparatus according to the invention comprises a hopper vessel 10 in which an auger 1) is arranged near the bottom, the shaft 12 of which is rotatably mounted on one end of the wall 13 of the vessel 10. , through the opening 14 in the opposite wall 15, and the container l
It is supported near the other end by a support arm 16 fixed to the outside of the wall 15 of the O.

The part of the outer shaft 12 of the container 10 firmly supports a bushing 17, which is provided with an L-shaped annular section 19 which, by means of three rotating arms 18, fixes a drum-shaped screen 20.

In the example shown, the screen is cylindrical in shape, but it could also be conical with its largest diameter at the end of the wall 15 of the container 10.

The drum-shaped screen 20 has grooves 21 formed in the outer bottom hopper feature wall 22 and end walls 23,24 of the container 10.
placed higher. A flexible conveyor element 21 moves over the bottom of said groove 21 and in the case shown consists of a row 125 with discs 26 at regular intervals, these discs extending radially from the rope 25. It stands out. The boundary wall 23.24 is provided with an inlet guide 27 and an outlet guide 28 for the conveyor element 25.26, which guide has a closed ring shape and moves in the direction indicated by the arrow 29.

In the illustrated case, the rotating part of the device consisting of the shaft 12, the auger 1) and the drum-shaped screen 20 is rotated by the radial disc rope conveyor element itself. For this purpose, the annular section 19 is provided with a sprocket 30 with which the disc 26 of the rope 25 cooperates. In particular, as shown in FIG.
The roped discs 26 acting on the sides of the teeth 31 rotate the sprockets 30 and thus the aforementioned rotating parts of the device.

A baffle plate 32 is attached to the container 10 and partially covers the auger 12 in the area where the feed is discharged by the auger 12 towards the opening 14 in the wall 15.

The function of the baffle is to prevent feed from moving directly through the opening 14 in an uncontrolled manner.

The method of operating the device according to the invention has been described above.

The feed material stored in granular or powdered form in the vessel 10 is discharged by an auger through openings in the vessel wall 15 and then passes to a drum-shaped rotary screen 20 . The mesh size of the screen is selected so that the useful material passes through the screen.The material then falls into the external channel 21 and is conveyed by a flexible conveyor element 25,26.

Since the rotational speed of the auger 1) corresponds to the advancing speed of the conveyor element, the amount of material discharged by the auger is always balanced with the amount of material brought in by said conveyor element. If the front end of the screen is open, foreign matter in the useful material will not pass through the mesh of the screen and will
It is discharged from the front of the screen as shown in the figure. If desired, an externally angled conical screen can be used to facilitate the evacuation of foreign matter collected in a suitable manner.

In the illustrated embodiment, the drum-shaped screen 20 has two areas of the screen, A and D, with mesh sizes of different sizes.
and the first one near the wall 15 of the container 10.
Area A has a small mesh and a second area towards the free end of the drum-shaped screen has a large mesh.

In such a case, the bottom wall 22 of the groove 21 closer to the small mesh screen area A is provided with an opening that allows small particulate material falling through the small mesh screen area to be discharged into the container C. B, and the material of useful particle size is conveyed through the channel by a conveyor element and falls through a large mesh screen. In the case of materials with small particle sizes that are smaller than the norm and pose problems in use, such a solution is advantageous when attempting to remove such materials from the discharged material. This is particularly advantageous when pelletized or granular feeds are used or when the proportion of fine particles that are dispersed in the air in farms (in the water in fish farms) during handling poses serious problems. .

In addition, a spiral rib is provided inside the drum-shaped screen,
Foreign matter may be discharged from the screen more effectively.

The main advantages of the device according to the invention are, firstly, the automatic adjustment of the material to the amount of material required by the conveyor elements, and secondly, the uniformly granulated or crushed material. It may be applicable to different types of materials used and therefore manual adjustment may be possible for different types of materials used. A fundamental advantage is the ability to remove foreign objects in the material that could damage the equipment structure, especially flexible conveyor elements.

With reference to FIG. 4, another embodiment of the device according to the invention is designated 1) 0, which comprises a central container 1 adapted to store the material to be fed to the conveyor system. ) 1, and in the example shown, said conveyor system is of the type comprising ropes 1) 2 restraining a plurality of spaced discs, said ropes forming closed loops within tubes 1) 4. It is controlled to move according to the following conditions. As is well known to those skilled in the art, openings are provided along the pipes 1) 4 provided in particular in feedlots (for example poultry farms) for the orderly discharge of feed into the feeding pan.

The storage container 1)1 has an inclined wall 1)5 inside which conveys the feed close to the auger 1)6.

One end of the auger 1) 6 is supported by the wall 1) 7 of the container 1) 1 and the other end is supported by the opposite wall 1 of the container 1) 1
) 8 and is provided with a screen 1) 9 which sieves the material fed by the auger 1) 6.
