Abstract
The invention discloses a feeding mechanism of a feeding type sieving machine. At present, a plurality of feeding rollers at the feeding section move continuously and uniformly, but since material at a feeding section is large in size and heavy in weight, the final speed of the feeding rollers cannot reach the speed of rollers at a sieving section, therefore, in order to drive material the friction between the material and the rollers at the sieving section is increased, which results in increasing the abrasion of the rollers at the sieving section, and shortening the service lives of the rollers. The feeding mechanism comprises a plurality of feeding rollers arranged side by side, and a power device for driving the feeding rollers to rotate; the feeding rollers are connected through a variable speed gear; the feeding rollers are enabled to accelerate step by step in the feeding direction; the speed of the feeding rollers close to a feeding end is low; after the material falls onto the feeding rollers, the material accelerates gradually with the feeding rollers to reduce the friction with the feeding rollers; and after the material accelerates, the speed of the material is approach to that of the rollers at the sieving section, the abrasion of the rollers at the sieving section is reduced, and the service life of the sieving machine is prolonged.

These characteristics of the present invention and advantage will be below the specific embodiment, accompanying drawing in detailed exposure.
[description of drawings]
The present invention is described further below in conjunction with accompanying drawing:
Fig. 1 is structural representation of the present invention.
[specific embodiment]
The invention provides a kind of feeder of feed formula sieving machine, comprise the some feed rollers that are arranged side by side and drive the engine installation that feed roller rotates, connect by variable-speed drive between the described feed roller, make described some feed rollers accelerate step by step along feeding direction.
Being in transmission connection between the feed roller of original feeder do not carried out velocity variations, the speed of each feed roller is identical, contrast original feeder, in the feeder of the present invention, the speed that material gets off from feed bin is zero acceleration step by step through feed roller, in the time of final material process feeder, its final velocity is close to the rotating speed of screening section roller; Feed roller accelerates step by step, the speed of first section feed roller is little, material accelerates step by step along feed roller, can significantly alleviate the friction of feed roller and material, thereby prolong the service life of feed roller, and feed roller is accelerated, the speed of material also increases, make material speed near the rotating speed of screening section roller, can reduce the wearing and tearing that material causes the screening section roller; Reduce equipment maintenance cost, increased service efficiency and the service life of whole equipment.
Be explained and illustrated below in conjunction with the accompanying drawing of the embodiment of the invention technical scheme to the embodiment of the invention, but following embodiment is the preferred embodiments of the present invention only, is not whole.Based on the embodiment in the embodiment, those skilled in the art belong to protection scope of the present invention at following other embodiment that obtains of the prerequisite of not making creative work.
With reference to figure 1, shown in the feeder of feed formula sieving machine, the some feed rollers that are arranged side by side on the frame 4 and the engine installation 3 that drives the feed roller rotation, connect by variable-speed drive between the feed roller, make feed roller accelerate step by step along feeding direction, near the speed minimum of feed end, near the speed maximum of discharge end.
Embodiment one:
With reference to figure 1, variable-speed drive comprises hinge wheel 21 and minor sprocket 22, described feed roller comprises the head feed roller 11 that is located at the feeder two ends, be located at least one stage casing feed roller 12 between two head feed rollers, near on the head feed roller of feed end big gear wheel 21 is set, near on the head feed roller of discharge end miniature gears 22 is set, be provided with hinge wheel 21 and minor sprocket 22 on the feed roller of stage casing, hinge wheel 22 on the feed roller of adjacent stage casing and minor sprocket 21 are replacing and are arranging, as figure, hinge wheel on the left end feed roller connects the miniature gears on the feed roller of adjacent right side, big gear wheel on the same feed roller connects the miniature gears of next feed roller then, so repeat, realize the transmission between each feed roller; Feed roller from the feed roller of feed end to discharge end all is that hinge wheel drives minor sprocket, forms the effect of accelerating step by step.
Embodiment two:
The chain driving fluid can change other type of drive into, for example belt wheel transmission, its structural principle is similar to the chain transmission, concrete structure is as follows: variable-speed drive comprises big belt wheel and small pulley, feed roller comprises the head feed roller that is located at two ends and is located at stage casing feed roller between the two head feed rollers, near on the head feed roller of feed end big belt wheel is set, near on the head feed roller of discharge end small pulley is set, big belt wheel and small pulley all are set on the feed roller of stage casing, big belt wheel and small pulley on the feed roller of adjacent stage casing are arranged alternately, connect big belt wheel and small pulley on the adjacent feed roller by belt, can realize that equally feed roller accelerates step by step along feed direction.
