Abstract

The invention discloses an automatic counting and weighing apparatus, integrated design of counting and weighing enables a user to feel the apparatus to be convenient and practical. Disclosed is the especially design of a sample disc: 1. a knife edge design with adjustable width before entering a discharge hole ensures a large sample to fall back to the sample disc and not to fall into a discharging gap, and enables the sample to be distinguished effectively before entering a counting photoelectric channel; 2. an especial slope surface design of the sample disc enables the sample to singly fall into the photoelectric channel for counting granule by granule in order before the sample enters the counting photoelectric channel, hence counting accuracy is ensured from the structure; 3. the photoelectric channel for adjusting susceptibility which is especially designed enables certain dust and undersize granules or broken samples to be not counted, so that counting is more accurate. The automatic counting and weighing apparatus is automatic, accurate and reliable in counting, weight of the sample for counting is also can be obtained after counting, so the automatic counting and weighing apparatus is convenient and practical. The automatic counting and weighing apparatus has wide practical value on the aspects of seed analysis and crop scientific research.

Description

A kind of full-automatic counting and weighing device

Technical field

The present invention relates to a kind of robot scaler of crop seeds sample, be specially a kind of can Auto-counting and weighing device.

Background technology

The counting of various crop seeds and mass of 1000 kernel metering are a loaded down with trivial details job being engaged in crops scientific research and producers, and existing all kinds of several instrument products have following deficiency at present:

1, do not possess the rejecting of granule and broken sample, counting makes the mistake;

2, the material loading passage of existing product is wider, and the material mixing for bulky grain sample and granule sample cannot be distinguished, and maybe will cause the sample of size particles all to count; Maybe, by occurring two and two parallel falling of above sample, cause few counting;

3, existing product does not have the function of weighing of every thousand corn weight;

4, existing product need to be selected different sample disc to the sample counting of different sizes, for operating personnel

Very inconvenient, and increased the cost of product.

Summary of the invention

(1) technical matters that will solve:

1, the sample of counting is carried out to automatic Weighing;

2, in to the course of conveying of sample by specially designed spirality slope, can make sample before entering the photoelectricity passage of counting, form a ground and enter successively photoelectricity passage, avoid two or more to fall the phenomenon that causes miscount simultaneously.

3, by being equipped with the adjustment of sensitivity of the photoelectricity passage of adjustable susceptibility, can reject the counting of dust granule and imperfect particle and fragment etc.

(2) technical scheme adopting:

The problems referred to above of the present invention are implemented by the following technical programs:

1, a high-precision adjustable automatic particle counter, it comprises to the Vib. of offering sample rising power source (3), is fixed on the sample disc (1) on Vib..

2, the upper device of described sample disc (1) has the adjustable edge of a knife that can adjust feeding track width, guarantees that the discharging track width in sample disc can regulate between 1mm-12mm.

3, in described sample disc (1), designed the skewed slot of special pearl, make sample materials at curved surface the last period that arrives discharging breach, by interior low outer high drop, design, and the curved surface Track desigh sharply declining along periphery circular direction can make material just form one before entering counting photoelectricity track to connect a ground and fall successively, guarantee the accuracy of counting.

4, it is upper that described Vib. (3) is fixed on four elastics (4) of elastomeric material, can make can not to have influence on the normal work of the other parts of instrument in vibrator works.

5, described LOAD CELLS parts are installed in bottom and are equipped with on the base plate of cushion (5) of rubber bodies, the effectively impact of separating vibration device on LOAD CELLS.

6, described Vib. (3) periphery is to be furnished with metal porous cover (2), and the electromagnetic wave producing while effectively intercepting vibrator works disturbs the signal of control module,

(3) the invention has the beneficial effects as follows and be:

Product monnolithic case is attractive in appearance, generous, simple in structure clear.

1, can make the just energy synchronization gain of the original very loaded down with trivial details counting work of various kinds crop seeds and the very first time of the weight of every thousand samples after Auto-counting completes;

2, can make original sample not of uniform size distinguish before being counted;

3, can make the conductively-closed when entering counting photoelectricity passage of some incomplete broken samples and dust granule, improve the counting accuracy of authentic sample.

Embodiment

Embodiment 1: sample disc is fixed on a Vib., sample materials requirement to be counted is placed in sample disc, sample disc is designed with special spiral slope, slope at discharging angle front end has carried out special design, the inner periphery of skewed slot and the difference of height of excircle have been strengthened especially, so that material sample can be close to the excircle side of the spiral slope of sample disc when arriving this face, material can one adjacent one be arranged in order towards discharging breach, at the specially designed slope of sample disc, designed the edge of a knife of adjustable spiral face width degree the last period, for effectively adjusting the width of material outlet face, make material can two or more material be mingled in large granular materials wherein and run simultaneously and enter the photoelectricity passage of counting.For dust and broken too small sample materials are not counted, by reducing the susceptibility of photoelectric counting, avoid this type of phenomenon to occur.LOAD CELLS has been designed in the below of pulp-collecting box, can make sample materials after being counted, at once obtain the actual weight of counted sample materials.Counting and the integrated design of weighing are a kind of new thinkings of patent of the present invention.
