Abstract

A sampling machine for powdery and granular dry materials composes a machine bracket (1), an electromotor (2), a gearing (5), a tooth-like sampling wheel (3), a sample storage box (4), an upper cover board (8) and a lower cover board (9). The electromotor (2) drives the gearing (5) and then the gearing (5) drives the tooth-like sampling wheel (3) circumgyrate on the lower cover board (9), thereby scraping the material away. The utility model is capable of controlling the amount of sample. The sampling structure is stable and reliable. The utility model is long-lived, compact, relatively light, and fulfils uninterrupted sampling of the sampling machine for powdery and granular dry materials.

Description

Powdery and granule dry state material sampler

Technical field

The utility model belongs to sampler, especially the equipment constructing technology field of concrete duct conveying sampler of sealing, semitight pipeline, groove conveying dry state material.

Background technology

Existingly be used to seal, semitight pipeline, groove carry the sampler of dry state material all to adopt pipe inside spin formula structure.Pipe inside spin body is a cantilever structure, during sampling, by spirochetal promotion rotation, make the sampling material be fed into sample storing box along the hand of spiral, there is following defective in the frame mode of this spiral sampling: the first, and sampler can not be regulated rotating speed, and sampling amount can not get control, cause sample storing box often to be filled, cause electromotor overload and scaling loss; The second, spiral is got material pipe and is cantilever structure, when the alluvial of sampling material is in pipe, will cause body to be bent or to fracture; The 3rd, the sped structure type is wide, weight is big, can not satisfy uninterrupted sampling and microsampling.

Summary of the invention

The purpose of this utility model provides a kind of for the weak point that overcomes above-mentioned prior art existence just and can sampling amount be controlled, sampling structure is reliable and stable, long service life, type is little, weight is lighter relatively, can satisfy the powdery and the granule dry state material sampler of uninterrupted sampling.

The purpose of this utility model is achieved by the following technical solution.

The utility model includes frame, motor, gearing, tooth shape sampling wheel, sample storing box and upper cover plate, lower cover, it is by the motor drives gearing, by the gearing transmission tooth shape sampling wheel is rotated on lower cover again, form scraping of material got.

Motor is a varying-speed motor; Gearing is gear drive, and its transmission progression is 2～5 grades.

Whole transmission device is a gear, and self is sealing state.Tooth shape sampling wheel is the formula of lying low with lower cover, half is fed into sampling in the pipeline, the sampling material is by the rotation of tooth shape sampling wheel, its whole hem width of taking turns thickness forms sweeping of material scraped by lower cover and gets, and then is rotated second half place that drives pipeline internal tooth form sampling wheel and drops down onto in the sample storing box of below.What and time of sampling amount are finished (market purchasing part) by programmable.The consumable accessory of this sampler is a tooth shape sampling wheel only, selects suitable material for use, and can prolong greatly its serviceable life.Because tooth shape sampling wheel is through the varying-speed motor speed governing, again through the multistage transmission of gear, period state of its stability and sampling is all good, unlikelyly causes the sample storing box spill-over and damages parts.And the serial sampling of this function, sampling amount can be controlled in per minute 6～20 grams.

Further set forth the utility model below in conjunction with Figure of description and embodiment.

Embodiment

Frame 1 is a metal framework, and gearing 5 places in the frame, is the gear of a sealing, and gear stage is elected three grades as.The rotating shaft of tooth shape sampling wheel 3 is fixed on the frame 1, and tooth shape sampling wheel 3 is installed to be provided with and abutted against on the lower cover 9, and small gap is arranged between the two.Upper and lower cover plate 8,9 passes through screw 6,7 with frame 1 capping, and motor 2 is fixed on the fuselage, and sample storing box 4 is fixed on the chute 10 that is positioned at the fuselage below, and its box mouth is corresponding with half parts in the tooth shape sampling wheel 3.The lead 11 of motor 2 is connected with controller.During use, the opening that tooth shape sampling wheel 3 is aimed at delivery pipe, groove is sent to about half, just can be taken a sample.

Claims (3)

1, powdery and granule dry state material sampler, it is characterized in that, it includes frame (1), motor (2), gearing (5), tooth shape sampling wheel (3), sample storing box (4) and upper cover plate (8), lower cover (9), it drives gearing (5) by motor (2), make tooth shape sampling wheel (3) go up rotation by gearing (5) transmission again, form scraping of material got at lower cover (9).

2, sampler according to claim 1 is characterized in that, motor (2) is a varying-speed motor.

3, sampler according to claim 1 is characterized in that, gearing (5) is gear drive, and its transmission progression is 2～5 grades.
