Abstract
ABSTRACT OF THE DISCLOSURE
In the vibration conveyor apparatus the bent side walls of a feeding trough are resiliently connected to each other and to a vibrator above the bottom wall of the trough.
This provides for more intensive oscillations of the trough and intensifies the feeding of the material being conveyed, while the throughput capacity of the apparatus is improved as a result of an increased effective cross-sectional area of the trough and elimination of the expulsion of the material being fed from the trough.

Description
1~)3~7Z
ll`he present in~entioll relates ~o vibration cor,veyor ap~aratus, and in particular ~o the apparatus to he ~lse-3 for feeditl-J grallular ma~erials alon(J inclined channels. ~ore specifically, the invention relates to the feeding of granular rocks after the mininy alony inclined mining excavations, as well as to the feeding of any granular materials from an upper level to a lower level along special channels.
~ t present, it is well known to use a belt and scraper or a plate and pendulum conveyor for feeding rocks along inclined mining excavations. The disadvantage of the belt and scraper conveyors is their unreliable operation under the above-mentioned conditions due to a rapid wear of belts and troughs of the conveyors as well as due to the expulsion of traction chains from the troughs. The disadvantage of the plate and pendulum conveyors is a large labour requirement for their assembly and disassembly, as well as their large size, which makes them operable only in the excavations having a substitute cross-sectional area, normally of at least 5 m2.
It is also known to use a vibration conveyor apparatus comprising a vibration trough cambered downwardly in direction from the forward loading end towards the rearward discharge end. This trough is provided with means for anchoring it in a channel and is connected to a vibrator (cf. USSR Inventor's Certificate No. 275835). During the feeding, the material moves from the top down along a smoothly concave surface.
The main disadvantage of such apparatus is that they are useful on short lengths only, normally not exceeding 5 m due to the aforesaid concavity of the working surface of the trough.
Vibration conveyor apparatus are also known having a trough disposed axially along the flow path of the material being fed. Among such apparatus may be mentioned that which has the bottom portion of the trough of a convex shape with , C
~ .
lV~s7z thc conve~i,ty di.rected inwardly o~ the trough, probably to intensi~y the stirring i,n the trough. The camber of the bottom wall is controlled hy means of hydraulic jacks support the vibration trough on the bottom of the excavation (see German Federal,Republic patent No. 11~9~52). The common disadvantage of such apparatus is their unreliable operation due to a rapid failure of hydraulic jacks and resilient support members taking-up heavy loads of the frame weight. In addition, the apparatus having the trough bottom wall with the convexity directed inwardly of the trough are complicated in the manu-facture and maintenance due to the intricate shape of the troughs and employment of the system of hydraulic support jacks described above. All the aforesaid disadvantages impair the reliabi.lity of operation of such conveyor apparatus.
Vibration conveyor apparatus are also known comprlsing a vertically triangular frame supported on the bottom of a.n excavation by resilient members, and a base. A vibrator is mounted within the frame. A receiving trough and a feeding trough are sequentially arranged on the inclined side of the frame along the direction of flow of the material being fed (see German patent No. 711362). These apparatus are disadvan-tageous because of their large size and unreliable operation due to a rapid wear of the elastic members taking up heavy loads of the frame weight during the operation.
It is known to use for feeding materials in under-ground excavations scraper arrangements which are unreliable due to a rapid wear of ropes and unproductive when feeding materials along mining excavations of a considerable length. ' According to the present invention there is provided a vibration conveyor apparatus for conveying granular material along an inclined channel, comprising a resilient member bent to form a trough having a bottom portion and side portions, ', C
me;ll-,s for ilnchoriTl-l said resiLient member at least at one point to the inclined channel with the trough aligned with the desired material flowpath, and a vibrator coupled to said side portions for impartinc3 a vibrating motion to the trough including flexure as the side portions therein.
The vibrator may be directly coupled to the side portions of the trough or may be mounted on a resilient inter-mediate member interconnecting the side portions of the trough.
The inventioll will be further described with reference to the accompanying drawings, in which:
Figure 1 is a front elevation of a vibration conveyor apparatus for feeding granular materials along inclined channels according to requirement of the invention;
Figure 2 is a front elevation of the apparatus according to another requirement of the present invention;
Figure 3 is a front elevation of the apparatus according to the present invention of a further embodiment;
Figure 4 is a front elevation of the apparatus according to a further embodiment of the present invention and;
Figure 5 is a longitudinal section of the detail of cantilevering of the feeding trough of the apparatus of Figures 1 to 4.
Referring to Figures 1 to 5 the apparatus comprises a feeding trough 1 disposed axially along the flow path of the material to be fed. The trough 1 is anchored to the bottom of an excavation by an angle support 2 (Fig. 5) received in a recess 3 in the bottom 4 of the excavation. The trough 1 is fixed by the support 2 bearing under gravity against the wall of the recess 3 via a resilient member 5.
The trough is formed from a bent resilient member the side portions of which are connected to each other above ~i 1~9 ;Z
Lhe bottom wall of the trough alld t~ a vibr~tor 6 (~igs. 1 to~) . Th~ ~i(ie portions of th~ trouc~h may be directly intcr-connected, and the vibrator 6 may be mounted at the joint between the side portions of the trou~h. In accordance with another embodiment the sides of the trough may be resiliently interconnected by means oE an intermediate member, the vibrator 6 being mounted on the intermediate member. The inter-mediate member may be a plate 7 (Fig. 2). The intermediate member may also be a spring 8 (Fig. 4). The intermediate member comprising the plate 7 is movably connected to the side walls of the trough in the horizontally transverse direction with respect to the direction of feeding of the material. The spring 8 is fixedly connected to the side walls of the trough.
Alternatively, the sides of the trough may be interconnected by means of the vibrator 6 (Fig. 3).
The advantage of all the above-described embodiments of the apparatus resides in the fact that during the operation of the vibrator, various oscillation modes occur in the trough resulting from the bending and unbending of the side walls of the resilient member. Due to such a complete utilization of the resilient properties of the trough, the oscillations of the trough 1 are intensified and the feeding of a material is likewise intensified, while the throughput capacity of the apparatus is improved and the effective cross-sectional area of the trough is increased so that the material being fed is prevented from being expelled from the trough as a result of intensification of the oscillations of the trough 1.
The apparatus may be installed as a single piece of equipment, or a plurality of such apparatus may be installed depending on the feeding length required. The apparatus may be successfully used both in closed inclined channels, e.g.
in ùnderground excavations, and in open channels, e.g. on r7z trc-~st].cs. In al,l. cases the trou(lll may he anchorc(l as clcscr:ibed above or in ally other aL~propriate manncr. Whcre a pl~rality of apparatus are install.ed in a sequence the troughs are mounted in such a manner that they partially overlap each other at the joints between the apparatus as shown in Fig. 5.
~fter the vibrators are put in operati.on an intensive feeding of a material begins from one trough to another along the entire feeding length. ~'he material is fed over the entire cross-section of the trough.
