Description

Sand cutter

Technical field

The utility model relates to a kind of sand cutter, belongs to sand cutter technical field.

Background technology

Sand cutter is machine sand material being broken into sand material, it by opening several groups of trepannings and hinged maracas head on row's circular bulkheads, hang down under axle rotates at dividing plate, the hammer hitting power that the rotation of maracas head rest bias is formed hits sand material, is beaten broken fines and crosses after net through diagrid and become sand material.

Utility model content

The utility model provides a kind of sand cutter, to be rolled thus obtains sand material, have production efficiency high by milling roller to sand material.

The technical scheme that the utility model adopts is:

A kind of sand cutter, funnel and the roller be arranged on below described funnel, described roller comprises two milling rollers, two described milling roller settings parallel to each other, the axis of two described milling rollers is positioned in same level, described milling roller is that fore-and-aft direction is arranged, line between the front end of two described milling rollers is perpendicular to the axis of described milling roller, two described milling rollers are disposed adjacent, rolling-compaction port is formed between two described milling rollers, described rolling-compaction port as described roller charging aperture and be connected with the discharging opening of described funnel, two described milling rollers are all downward turning to of described rolling-compaction port place.

Select as one, two described milling rollers rotate respectively by a driven by motor.

Further, described motor can be in transmission connection by reductor and described milling roller.

Select as one, the distance between two described milling rollers is adjustable.

Preferably, two described milling rollers form a milling roller group, the quantity of described milling roller group is multiple, multiple described milling roller group is setting up and down, and the axis of all described milling rollers is parallel to each other, the rolling-compaction port of the milling roller group of the upside in adjacent two described milling roller groups is greater than the rolling-compaction port of the described milling roller group of downside.

Further, the quantity of described milling roller group is 3.

The beneficial effects of the utility model:

The utility model is by the setting of two milling rollers, sand material enters between two milling rollers, due to the rotation of two milling rollers, make sand material by the rolling-compaction port between two milling rollers, and the size of rolling-compaction port less (being less than the size of sand material), thus sand material is rolled between two milling rollers, thus sand material is crushed, in terms of existing technologies, adopt the technological means of milling roller more simple, cost is also lower, and can ensure that in the process rolled each sand material is all rolled to, efficiency is higher.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Wherein: 1, funnel; 2, milling roller.

Detailed description of the invention

See Fig. 1, the utility model provides a kind of sand cutter, funnel 1 and the roller be arranged on below described funnel 1, described roller comprises two milling rollers 2, the setting parallel to each other of two described milling rollers 2, the axis of two described milling rollers 2 is positioned in same level, described milling roller 2 is arranged in fore-and-aft direction, line between the front end of two described milling rollers 2 is perpendicular to the axis of described milling roller 2, two described milling rollers 2 are disposed adjacent, rolling-compaction port (not marking in figure) is formed between two described milling rollers 2, described rolling-compaction port as described roller charging aperture and be connected with the discharging opening of described funnel 1, two described milling rollers 2 are all downward turning to of described rolling-compaction port place.

The course of work of the present utility model is: loaded by sand material in funnel 1, sand material flow in the rolling-compaction port between two milling rollers 2 from funnel 1, and two milling rollers 2 now rotate (preferred rotating speed is identical), because milling roller 2 is downward in the direction of motion at rolling-compaction port place, and then two milling rollers 2 form a downward snap-in force at rolling-compaction port place, the effect that sand material is subject to this snap-in force at rolling-compaction port place moves downward, and the gap between two milling rollers 2, thus sand material is pulverized.

Certain two described milling rollers 2 rotate respectively by a driven by motor, ensure the power driving milling roller 2 to rotate, and then guarantee that sandstone is pulverized.

In order to ensure rolling effect, also following improvement can be done.

Two described milling rollers 2 form a milling roller group, the quantity of described milling roller group is multiple, multiple described milling roller group is setting up and down, and the axis of all described milling rollers 2 is parallel to each other, the rolling-compaction port of the milling roller group of the upside in adjacent two described milling roller groups is greater than the rolling-compaction port of the described milling roller group of downside.

That is, many covers setting up and down roll group, sand material is first rolled by the uppermost group that rolls, sand material after rolling fall into below roll group, the group that rolls below continues to roll, until sand material is rolled by the group that rolls of bottom, like this, sand material rolls through multiple, thus ensures that sand material is pulverized completely.

In order to better roll sand material, the rolling-compaction port of the milling roller group of the upside in adjacent two described milling roller groups is greater than the rolling-compaction port of the described milling roller group of downside, by such setting, sand material can first be rolled by larger rolling-compaction port (corresponding rolls group), first sand material is rolled the sand material of the size being less than corresponding rolling-compaction port, by the sand material after rolling, drop to below roll in group, because the rolling-compaction port of below is more young than rolling above, so sand material continue roll less, in this way, until sand material rolls rolling of group by bottom.

Sand material is carried out classification roll, can alleviate and eachly roll the pressure that rolls of group to sand material, and then reduce the wearing and tearing to milling roller 2, extend service life of the present utility model.

The described quantity rolling group is preferably 3.

Other are arranged:

Described motor via reducer and described milling roller 2 are in transmission connection, and the distance between two described milling rollers 2 is adjustable.

It is emphasized that, because all sand materials all can be rolled by milling roller 2, and then the width (distances between two milling rollers 2) being all less than the minimum place of rolling-compaction port by the particle diameter of the sand material after rolling can be ensured, and the width of rolling-compaction port can artificial adjustment (being adjusted to the particle diameter of the sand material of needs), so all meet the standard of sand material from the particle diameter of rolling-compaction port sand material out, and without the need to carrying out the process of sieving.

For the description of the preceding paragraph, for multiple milling roller group, only need guarantee that the rolling-compaction port of the milling roller group of bottom meets corresponding standard.
