Abstract

A conical adjustable slit contracting divide device with a scraping sweep and a vibration device, which comprises a frame and a feed hopper, a file sample chute, a material abandoning cover and a decelerator which are arranged on a framework, wherein a conical inner tube is connected to an output shaft of the decelerator of which the pyramidal face can be sleeved by a outer tube, and two tube bodies are provided with at least two holes and file regulating device for regulating the relative position. The utility model is characterized in that a bur scraping sweep device is provided on the material abandoning cover and is fixed through a support stand. The utility model is capable of scraping the bur on the inner wall and the outer wall of the conical tube, to reduce the cross contamination between the sample, and avoids the defect that the sample produces essentiality divagation and the sampling accuracy can not meet demand. Besides, the bur in the contracting divide device can be quivered off by the vibration device to further reduce adherence chance, so the floating of the material is further smooth. The adjustable slit device of the utility model is capable of adjusting the relative position between the open holes of the conical inner tube and the outer tube, to adjust the contracting divide ratio.

Embodiment:

As shown in Figure 1, the utility model comprises support 1, frame 3 and abandons material cover 6, the described material cover 6 of abandoning is positioned at frame 3 centre positions, feeder hopper 11 is located at frame 3 upper positions, be connected by bolt and abandon on the material cover 6, divide into the elephant trunk 12 that keeps sample, this elephant trunk outlet is positioned at frame 3 bottoms, and the material after the division can flow out by this pipe.Speed reduction unit 8 also is fixed on by bolt and abandons on the material cover 6, and its output shaft is abandoned interior the taper inner core of material cover 69 and is fastenedly connected by key with being located at, and by its driven rotary, exports axle head and be provided with the stop packing ring, can prevent its slippage.Be sheathed with taper urceolus 10 in taper inner core 9 outsides, its conical surface barrel is located at feeder hopper 11 outlets and is kept sample between elephant trunk 12 inlets, all offers the corresponding homalographic oblong aperture in two or more positions on the two cylindrical shell conical surfaces; Described slit regulating device 13 comprises bearing seat 20, bearing 21, gear shaft 22, gear ring 23, bearing seat 20 is by being bolted to taper inner core 9 stub ends, bearing 21 is housed in it, gear shaft 22 places in the bearing 21, one end is provided with gear, can be meshed with the gear ring 23 that is fixed on taper urceolus 10 stub end outer walls, the other end is processed into square side's tenon, the cover upper ejector lever can make gear shaft 22 rotations, drives gear ring 23 simultaneously and rotates, and taper urceolus 10 also rotates thereupon, relative position between

taper urceolus

10 and 9 perforates of taper inner core is changed, with perforate slit on two cones that stagger, change the flow area of perforate on the cylindrical shell, thereby regulate its division ratio.When 10 rotations of taper inner core 9 and taper urceolus, can cut the streams of getting off from feeder hopper 11, the slit aligns upper feed hopper 11 and bottom when keeping sample elephant trunk 12, and the streams by the slit enters the elephant trunk 12 that keeps sample; Not to timing, never porose taper urceolus 10 outer walls of material flow to abandons material cover 6, discharges from the bottom.

The utility model is at the defective of present prior art, be provided with one on the material cover 6 and scrape and sweep bur device 7 abandoning, as shown in Figure 2, it comprises inside strake 14, outer scraper plate 18, lever arm 15 and bearing 17, wherein inside strake 14 is fitted with taper inner core 9 inwalls, lever arm 15 1 ends are hinged with it by bearing pin, and the other end is hinged by bearing pin and bearing 17, and bearing 17 is fixed on to be abandoned on the material cover 6.Outer scraper plate 18 is fitted with taper urceolus 9 outer walls, and another lever arm 15 1 ends are hinged with it by bearing pin, and these lever arm 15 other ends are with hinged by bearing pin and another bearing 17, and this bearing 17 is fixed on abandons material cover 6 another locations.For guaranteeing to fit tightly with taper inner core 9 inwalls and taper urceolus 9 outer walls on inside strake 14 and the outer scraper plate 18, at lever arm 15 with abandon material and be equipped with an extension spring 16 between covering 6.Because the outer wall of the inwall of taper inner core 9 and taper urceolus 10 has a small amount of bur of wet stock when rotated, sweep bur device 7 and scrape and sweep through scraping, can reach the purpose of removing bur, the reason bur does not cause sample to pollute mutually.
