Abstract

The utility model discloses an instant dispersity sample release device and aims to solve the problem of discharge uniformity. The instant dispersity sample release device comprises a sample cartridge, a hinge, a torsional spring, a rotary shaft, a discharge door, a damping corner, a rotary arm, a proximity switch, and a motor. The sample cartridge is fixed on the hinge. The hinge is provided with the rotary shaft. The discharge door is disposed at the lower end of the sample cartridge and can rotate around the rotary shaft. The torsional spring is fixed between the hinge and the discharge door, so that the discharge door tends to open under the action of the torsional spring. The rotary arm is disposed at the lower end of the discharge door and driven by the motor. Shift forks of the rotary arm are abutted to the discharge door. The proximity switch is used for controlling operation of the motor. In order to solve the problem that motor load is large due to small force of arm when the shift forks of the rotary arm contact with the discharge door, one of the two shift forks of the rotary arm is higher than the other. The instant dispersity sample release device has the advantages that automatic control guarantees discharge uniformity and the function of instant release of dispersity samples is realized.

Description

A kind of degree of dispersion sample abrupt release device

Technical field

The utility model relates to instrument field, is a kind of sample releasing device specifically.

Background technology

The fast development of modern science and technology, require the precision of some measuring instruments more and more higher, especially some degree of dispersion measuring instruments adopt manual feeding manner in the past, cause the conformability that detects data relatively poor, its reason is, bigger related of speed, the angle existence of the data of measuring during with charging, and M/C can't guarantee the conformability of each feeding manner.

The utility model content

For solving the problems of the technologies described above, the purpose of this utility model provides a kind ofly has automatic release sample, and the higher degree of dispersion sample abrupt release device of conformability, and concrete scheme is as follows:

A kind of degree of dispersion sample abrupt release device, comprise sample box, hinge, torsion spring, rotating shaft, down bin gate, damping angle, pivoted arm, near switch, motor; Described sample box is fixed on the hinge, and described hinge arranges rotating shaft, and the lower end of sample box is following bin gate, and described bin gate is rotatable around described rotating shaft down, and torsion spring is fixed between hinge and following bin gate, feasible under bin gate be subjected to the effect of torsion spring that the trend of unlatching is arranged; Blanking student end is pivoted arm, and described pivoted arm is by motor-driven, the shift fork of described pivoted arm and following bin gate butt; The described running that is used for the control motor near switch.

When just having contacted with following bin gate for solving the pivoted arm shift fork, the arm of force is less, cause the bigger problem of motor load, the shift fork of described pivoted arm is two, the height of one of them is lower than the height of another one, at first contacted with following bin gate by highly less shift fork, then highly bigger shift fork will descend again bin gate further with sample box lower end butt.

For protecting down bin gate, described blanking student side arranges the damping angle.

The utility model has the advantages that: control automatically, guaranteed the conformability of blanking, realized the function of degree of dispersion sample abrupt release.

Principle of the present utility model is: following bin gate is subjected to the effect of torsion spring that the trend of unlatching is arranged, pivoted arm rotation front shift fork, namely highly less shift fork contacts with following bin gate earlier and makes down the bin gate angle of closing, back shift fork then, and namely highly bigger shift fork will descend bin gate to cut out fully.Pivoted arm stops operating when touching near switch, and this moment is when descending the bin gate closure just.Sample is added in the sample box, and the rotation of starter motor pivoted arm makes the back shift fork leave blanking and descends bin gate moment unlatching behind the door again, and sample falls, and has guaranteed the conformability of each blanking, realizes accurate test function.

Description of drawings

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

Fig. 2 is shift fork and the scheme drawing that cooperates of following bin gate.

The specific embodiment

Specify the utility model below in conjunction with accompanying drawing, as shown in Figure 1, the utility model comprise sample box 1, hinge 2, torsion spring 3, rotating shaft 4, down bin gate 5, damping angle 6, pivoted arm 7, near switch 8, motor 9; Described sample box 1 is fixed on the hinge 2, described hinge 2 arranges rotating shaft 4, and the lower end of sample box 2 is following bin gate 5, and described bin gate 5 down is rotatable around described rotating shaft 4, torsion spring 3 is fixed on 5 of hinge 2 and following bin gates, makes that bin gate 5 is subjected to the effect of torsion spring 3 that the trend of unlatching is arranged down; Following bin gate 5 lower ends are pivoted arm 7, and described pivoted arm 7 is driven by motor 9, the shift fork of described pivoted arm 7 and following bin gate 5 butts; The described running that is used for control motor 9 near switch 8.

When just having contacted with following bin gate for solving the pivoted arm shift fork, the arm of force is less, causes the bigger problem of motor load, and the shift fork of described pivoted arm is two, is respectively first shift fork 71 and second shift fork 72, and the height h1 of described first shift fork 71 is higher than the height h2 of second shift fork 72.Namely at first be that the second highly less shift fork 72 contacts with following bin gate 5, first shift fork 71 contacts with following bin gate 5 subsequently.
