Description

Laboratory soil screening device

Technical Field

The utility model belongs to the technical field of small-size sieving mechanism, concretely relates to laboratory sieve native device.

Background

When carrying out the experiment of indoor test soil correlation physicochemical property, the laboratory staff often need obtain the soil particle of different particle diameters, just can carry out the survey of corresponding experimental index.

At present, some common indoor soil screening devices in the market can only screen one sample at a time, and every time the sample is screened, the sample is taken out and changed and the sieve is fixed again, so that the time and the labor are consumed, a dust collecting device is not used for collecting falling dust, and the demand for different particle size soil samples can not be adjusted.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a laboratory soil screening device, this soil screening device easy operation once only can let a plurality of soil samples sieve simultaneously, screens different particle diameter soil samples simultaneously, can greatly improve soil screening efficiency.

The utility model discloses the technical scheme who adopts is, laboratory sieve native device, including sieve soil box, its characterized in that, sieve soil box inside is fixed with at least two sets ofly and is fixed in the detachable screen utensil of sieve soil box inside through the pole setting, and the screen utensil sets up two-layerly for a set of at least, still including the power part of control sieve soil box and the dust collecting device of setting in sieve soil box below.

The utility model is also characterized in that the dust collecting device is in the shape of a micro-horn, the outer side of the dust collecting device is provided with a bayonet, and a collector is arranged on the bayonet.

The power component comprises a vibration motor and a spring, the vibration motor is connected with the soil sieving box and is controlled by a switch arranged on the side surface of the soil sieving box, and the other end of the spring is connected with the bottom frame.

One end of the spring is connected with the bottom frame through the lower base, and the other end of the spring is connected with the soil sieving box through the upper base.

The beneficial effects of the utility model reside in that:

the soil screening device can ensure that a plurality of soil samples are screened at most at one time, is convenient to operate and does not need complex fixed procedures, and time is saved.

The utility model discloses soil screening device has set up dust collecting device, can collect the soil sample that drops carelessly in operation process, keeps the device clean and tidy nature.

The utility model discloses it is more convenient because put the sample to sieve native device, at sieve appearance in-process, can in time adjust according to the demand to different particle diameter soil samples.

In the figure, 1, a soil screening box; 2. erecting a rod; 3. a sifter, 4. A switch; 5. a dust collecting device; 6. a vibration motor; 7. a spring; 8. a lower base; 9. a chassis; 10. and (4) an upper base.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

The utility model discloses laboratory soil screening device's structure is as shown in figure 1, including the power part of screening soil box and control screening soil box vibration.

The inside sieve utensil that is fixed with of soil screening case, the sieve utensil sets up two-layerly as a set ofly at least.

The main operation principle of the device is as follows: the vibrating motor 6 is used as a vibration source of the whole machine, the vibrating motor 6 directly drives the soil sieving box 1 on the upper part to move in the horizontal direction through the starting switch 4, and the spring 7 on the bottom frame plays roles of buffering and supporting.

And then the soil screening box 1 drives the screening device 3 to vibrate under the action of the vibration motor 6, so that the soil particle size required by people is screened layer by layer to obtain the soil particle size required by people.

As shown in figure 2, the soil screening box 1 is uncovered and located at the upper part of the device, the interior of the soil screening box mainly comprises four vertical rods 2, a screening device 3 and a dust collecting device 5, and the exterior of the soil screening box is provided with a switch 4. Four uprights are welded at the bottom of the soil sieving box 1, and the dust collecting device 5 is positioned at one side below the box.

For the soil screening box 1, in the using process, the screening tools 3 with required particle sizes are only needed to be overlapped and placed in four corners controlled by the box body and the upright rods 2, and a matched cover is covered on the screening tool 3 at the uppermost part to prevent soil samples from spilling; after the soil sample is screened, directly taking out the screened soil sample from the upper surface, and simultaneously putting another group of soil samples needing to be screened.

As shown in fig. 2, the connection mode of the power component of the lower part is as follows: the upper base 8 direct connection of vibrating motor 6 and spring 7 top is in the lower part of sieve soil case 1, and the upper end of spring 7 is direct and upper base 8 fixed connection, and the lower extreme of spring 7 is direct and the lower base 10 fixed connection of downside, and lower base 10 is fixed on the chassis.

Two ends of a rotor shaft of the vibration motor 6 are respectively provided with a group of adjustable eccentric blocks, so that the vibration motor can do circular or elliptical vibration, and the purpose of screening is achieved.

The spring 7 should be selected to have a supporting function as well as a cushioning function.

Fig. 3 is a top view of the soil screening box, and it can be seen that the soil screening box 1 comprises four vertical rods 2 for controlling the movement of the screening device, the screening device is placed in four corners controlled by the vertical rods 2 and the box body, at least two layers of screen meshes with sequentially reduced apertures are arranged from top to bottom, and a dust collecting device 5 is arranged on one side below the soil screening box, and under the action of a vibrating motor 6, dust can slide into the dust collecting device 5.

The utility model discloses a design has solved the slow problem of sieve native efficiency, and the device once only can guarantee that a plurality of soil samples sieve simultaneously (depend on the quantity of sieve) to it is very convenient to put the sample of getting soil, has greatly improved sieve native efficiency.
