Description

A kind of divider for dividing equally solid powder or granular substance

Technical field

It is a kind of for dividing equally the equal of solid powder or granular substance specifically the present invention relates to test equipment field Divide device.

Background technology

In chemistry experiment, teacher or assistant are needed often before doing experiment solid powder or granular Chemical substance is divided into several pieces, is then redistributed in different groups of storage bottle, to ensure that different experiments group being capable of almost phase With material condition under tested, so as to be carried out to test data or phenomenon effectively record and observe, if every group of experiment Substantially, this may obtain the larger test data of deviation ratio to deal gap, or not observe the reacting phenomenon that should be observed Deng.Some single factor experiments also may require that in addition to Testing factors other factorses should be the same terms, therefore be also required to distribute The base stock of identical deal.

In general, some teaching tests can give different groups of preparations enough experimental raws, allow experimenter voluntarily to weigh suitable The test raw material of amount, but this arrangement can be different because of the qualification of operator, cause to weigh inaccurate or pollution experiment Raw material；It is manually to weigh and distribute identical deal to prepare before some experiments, but this method wastes time and energy, influence work effect Rate, and be also easy to pollute experimental raw.

The content of the invention

Wasted time and energy for solid powder or graininess chemical substance process is manually divided equally present in prior art, also held The problem of artificial contamination is easily caused to raw material, the invention provides a kind of for dividing equally dividing equally for solid powder or granular substance Device, the divider is easy to operate, allocative efficiency is high and error is smaller, disclosure satisfy that the distribution requirement of most of teaching experiments.

To realize above-mentioned technical purpose, the technical solution adopted by the present invention is as follows：

A kind of divider for dividing equally solid powder or granular substance, including the box body with cavity, in the middle part of box body Vibrating bar grizzly net, the vibrating bar grizzly net divides the cavity into feeding material chamber and sub-material room two parts, and being provided with the feeding material chamber to hold Receive the material-storing box of solid powder or granular substance, the bottom of the material-storing box has a small opening for being capable of folding, and material-storing box bottom with A certain distance is left between vibrating bar grizzly net, the reception box of some grade capacity that can be extracted out, institute are provided with the sub-material room Four angles for stating vibrating bar grizzly net are provided with elastic device, and the side of vibrating bar grizzly net is provided with vibrating motor.

Using the invention of above-mentioned technical proposal, its operation principle is as follows：Foot is weighed according to every group of deal and group number first The experimental raw of amount, is poured into feeding material chamber, and after after floating experimental raw, Vibration on Start-up motor opens small opening, now feeding The experimental raw of room falls into vibrating bar grizzly on the net, and in the presence of vibrating motor, elastic device, vibrating bar grizzly Netcom shakes up and down excessively It is dynamic enable to experimental raw to sieve after enter successively in sub-material room it is some wait capacity to receive in box, when the experiment of feeding material chamber is former After material all falls, small opening just can be closed, after after all experimentss raw material uniformly sieving, just can close vibrating motor, taken out and receive , thus substantially be assigned to experimental raw in the reception box of the capacity such as some by box.

A certain distance is wherein left between material-storing box bottom and vibrating bar grizzly net and is to provide for enough space guarantees Vibrating bar grizzly net up-down vibration, and for prevent material-storing box bottom too near with vibrating bar grizzly net, when vibrating bar grizzly net shakes When dynamic, easily part Experiment raw material is shaken in feeding material chamber from small opening.

Furthermore, if vibrating bar grizzly net only sets vibrating motor, this can cause vibrating bar grizzly net rigidly to vibrate, and be easily damaged Divider parts, reduce its service life, and elastic device can provide certain cushioning effect just, protect divider structure, Corresponding lifting service life.

Further limit, the sub-material room is provided with sliding bottom, sliding bottom both sides are provided with rail plate, it is described some etc. The reception box of capacity is placed on sliding bottom.So can directly by the reception box of sliding bottom and its capacity such as some directly from Extracted out in sub-material room, the experimental raw distributed in box is received to take.

Further limit, it is described reception box outlet port upper end be extended with scraper plate straight down, the scraper plate with receive box upper table Face flushes and scraper plate is perpendicular to the reception box direction of motion.Above-mentioned restriction is to prevent the experimental raw for receiving box upper surface from piling up Cause to receive that the distribution of box deal is uneven, when the reception box of sliding bottom and its accommodating capacity such as some is extracted, scraper plate is just The soil for receiving box surface can be struck off well so that deal distribution of the experimental raw in each reception box is more uniformly distributed.

Further limit, the vibrating bar grizzly net includes the square fixed mount of the filter screen of matching cavity and fixed filter screen, institute Elastic device, vibrating motor is stated to be arranged on fixed mount.After vibrating motor is installed together with fixed mount, vibrating motor can Fixed mount is driven to vibrate together, because filter screen is fixed in fixed mount, it is ensured that effective vibration of filter screen, similarly, elasticity dress Put the cushioning effect that can also ensure vibrating bar grizzly net in the case of fixed mount is indeformable.

Further limit, stating elastic device includes locating dowel and vibrating spring, and the locating dowel lower end is fixed on branch cavity Bottom, leaves vibration gap between upper end and fixed mount, be enclosed within locating dowel outside the vibrating spring, wherein vibrating spring lower end It is also secured on cavity inner wall, upper end is connected with fixed mount.Locating dowel can prevent vibrating spring from existing in being built in vibrating spring Produced during up-down vibration it is larger be axially displaced from, locating dowel upper end and principal oscillation sieve between leave vibration gap, can keep away Exempt from locating dowel and hinder fixed mount buffer falling.

Present invention design is ingenious, the common experimental raw material such as solid powder or graininess effectively can be divided into several pieces, As long as so test operation is correct, should just obtain the little experimental data of difference, observe similar experimental phenomena, should divide equally Device is easy to operate, and sample distribution error is small, and respectively efficiency high, can fully meet the basic demand of teaching test.
