Abstract

The utility model discloses a star hobbing sieving machine, which comprises a machine base, a machine box and a power device. The utility model is characterized in that the bottom part of the machine box is provided with shafts with same distance, and the shafts are provided with rack units which are axially distributed with same distance. The rack units are at least provided with three racks which are distributed uniformly. The rack units which are arranged on the neighboring shafts are staggered mutually. The power device which is arranged at the outer side of the machine box is connected with one shaft. Chain drive mechanisms or gear drive mechanisms are arranged among the shafts which are arranged at the outer side of the machine box. The upper part of one end of the machine box is provided with a material feeding hole, and both ends of the lower part of the machine box are respectively provided with lump material discharge hole and a material discharge hole. The utility model has the advantages that lump materials and sundries can be removed and the efficiency is high, and also has advantages that the sieving machine is suitable for sieving wet fine materials, and the sieving efficiency is high.

Description

Star gear hobbing screening machine

(1) technical field: the utility model relates to a kind of screening plant, is particularly suitable for the star gear hobbing screening machine of bulk material screening.

(2) background technology: bulk cargo in the industries such as electric power, mine, cement, coal, metallurgy carry and screening in, need remove foreign material such as the bulk materials in the bulk cargo and iron wire, big gun line, batten, braids.At present the foreign material in the bulk cargo are removed and also do not had proprietary equipment, and the equipment of bulk materials in the removal bulk cargo, a kind of swing type screening machine is arranged, and it is to utilize the broach that is fixed on the swinging axle to form the screening grid, and being in tilted layout by compass screen surface is removed the bulk materials downslide.This equipment has following shortcoming, and bulk materials relies on the angle downslide of tilting to get rid of, and does not have the power of removal, and it is low to remove efficient; Contain moisture when big at bulk cargo, powder material can be bonded on the broach surface, the screening grid is diminished, even stop up, and screening efficiency is low; This equipment volume and weight are huge, are difficult to be arranged in the induction system; Can not remove foreign material, the material of band foreign material enters in the follow-up equipment (as coal breaker), and its working condition is worsened, and shortens service life etc.

(3) summary of the invention: the utility model technical issues that need to address are that a kind of bulk materials of can removing of design can be removed the high star gear hobbing screening machine of foreign material and screening efficiency again.The technical solution of the utility model is, star gear hobbing screening machine, comprise support, cabinet and power set, it is characterized in that: the cabinet bottom is along laterally being provided with equidistant axle, the axle two ends are rotatably assorted in the side plate hole of cabinet, be provided with transmission mechanism between each, at least be evenly equipped with three tooth bar groups on the cross section of each, this tooth bar group equidistantly distributes vertically on each axle, tooth bar group on the adjacent shaft is axially staggering mutually, and the length of tooth bar is less than or equal to the cylinder distance of adjacent two between centers, and the top of cabinet one end is provided with charging aperture, the bottom of the other end is provided with out piece material mouth, is provided with discharging opening in the bottom relative with axle.Transmission device between each is, respectively is provided with identical sprocket wheel on the axle outside cabinet side board, is two sprocket wheels on each outside two end axles wherein, is connected with chain respectively on the sprocket wheel relative with its both sides of two sprocket wheels on axle.Transmission device between each can also be each gear that is provided with the identical number of teeth, is provided with the gears engaged of the identical idler gear of the number of teeth and its both sides between each gear.The utility model is owing to be distributed with the tooth bar of interlaced arrangement on the axle that is parallel to each other in cabinet, each is with identical rotating speed and turn to rotation, bulk materials on the tooth bar and foreign material move on to discharging opening from charging aperture and are excluded under the stirring of tooth bar, tooth bar is disposed mutually incessantly and is bonded at its lip-deep powder, thereby this screening machine compared with the prior art, not only have the function of removing bulk materials, also have the function of removing foreign material, and have the high advantage of screening efficiency.

(4) description of drawings: Fig. 1 is a front view of the present utility model, and Fig. 2 is the left side view of Fig. 1, and Fig. 3 is the vertical view of Fig. 1.3. 4. tooth bars of 1. supports, 2. cabinets, 5. sub-material bars, 6. power set, 7. sprocket wheels, 8. chains among the figure.

(5) specific embodiment: the utility model includes support 1 and can be installed in the induction system or on the basis of fastening, cabinet 2 is connected on the support, bearing on the six roots of sensation axle 3 is along in the bearing block that laterally is installed in equidistantly in the cabinet bottom side plate, the plane of structure of each is provided with 4 groups of mutual vertical tooth racks, this tooth bar group is distributed on six axles vertically equidistantly, and the tooth bar on the adjacent shaft is axially staggering mutually.Shaft extension outside cabinet be located at cabinet outside power set 6 be connected, outer each of cabinet is provided with sprocket wheel 7, wherein except that two end axles has only a sprocket wheel, be equipped with two sprocket wheels on all the other axles, chain connected mode between sprocket wheel is that relative sprocket wheel is provided with chain on the left-hand axis that is adjacent of a sprocket wheel on, relative sprocket wheel is provided with chain on the right-hand axis that another sprocket wheel on this is adjacent, sprocket wheel on each is all identical, thereby six axles with identical turn to synchronization change with, turn to the tooth bar that should make cabinet inside top by after change forward.As sieve aperture, thereby the tooth bar group depends on the granule size of requirement material to this screening machine in axial spacing by the gap between the tooth bar.Can the length of tooth bar relate to owing to keep the hole of compass screen surface constant during folding between the tooth bar, and the tooth bar number of tooth bar group is big, and the length of tooth bar can reduce, but tooth bar length is preferably distance between the cylinder that is slightly less than adjacent diaxon, and it is best that it gets rid of bulk materials effect.The another kind of mode of the transmission mechanism of each between centers is, establishes a gear that the number of teeth is identical on each fully, is provided with the identical idler gear of a number of teeth between each gear and is meshed with the gear of its both sides.

The utility model compared with the prior art, has tooth bar and stirs bulk noncombustibility owing to adopted the rotation rack structure Material and the high advantage of foreign material effect, the while tooth bar of each axle arranges alternately, can be with being glued on the rack surface Thin wet stock is disposed, thereby has the high advantage of screening efficiency, and himself is in light weight, and power consumption is few, Be convenient to arrange in induction system.
