Problems solved by technology

The existing sample weighing and sampling device generally adopts a manually operated sampling spoon. During the weighing process, vibration is generated by tapping the medicine spoon with a finger, and the amount and speed of the addition amount can be grasped by controlling the force of the finger tapping. Due to the small amount of sample required in the experiment and high requirements for weighing accuracy, it is difficult to control the force of the fingers, which often results in excessive addition, resulting in repeated weighing affecting the weighing speed and weighing accuracy.
On the other hand, since the existing sampling spoons are not of a sealed structure and do not have the function of mechanical automatic sampling and weighing, the sampling spoons containing the samples are prone to spilling when they are moved to the balance, which brings inconvenience to the experiment.

Embodiment 1

[0023] Such as figure 1 As shown, the device of the present invention includes a fixed plate 1, a guide mechanism 2 is fastened to one side end surface of the fixed plate 1, and a relatively sliding sampling spoon 3 and an auxiliary sampling cover 4 are arranged on the guide mechanism 2, and the auxiliary sampling cover 4 It is used to close the sampling spoon 3; a driving device 5 is provided on the other end surface of the fixed plate 1, and the driving device 5 is used to control the sliding of the sampling spoon 3 and / or the auxiliary sampling cover 4.

[0024] In order to shake off the sample stained on the outer wall of the sampling spoon 1 and to ensure that the samples in the sampling spoon 1 are dropped evenly and reliably, a vibrator 6 can be arranged on the sampling spoon 1 and / or the auxiliary sampling cover 4 .

[0025] Wherein, the guide mechanism 2 includes a slide rail 7 fastened to one side end surface of the fixed plate 1 and arranged horizontally, and the sa...

Embodiment 2

[0036] For the sake of brevity, in the description of this embodiment, the same technical features as those of Embodiment 1 will not be described, and only the differences between this embodiment and Embodiment 1 will be described:

[0037] Such as Figure 4 As shown, the guide mechanism 2 includes a horizontally arranged fixed block fastened on one side of the fixed plate 1, and a guide groove 15 penetrating the fixed plate 1, a sampling spoon 3 and / or an auxiliary sampling cover are provided on the fixed block. 4 is slidably inserted in the guide groove 15, and the sampling spoon 3 and / or the auxiliary sampling cover 4 moves along the length direction of the sampling spoon 3.

[0038] In order to adjust the opening and closing speed and stability between the sampling spoon 3 and the auxiliary sampling cover 4, the driving device 5 can be connected with one end of the sampling spoon 3 and / or the auxiliary sampling cover 4 through a rack and pinion mechanism. The rack is arra...

Abstract

The invention relates to a mechanical sampling spoon which comprises a fixing plate, wherein a guide mechanism is arranged on the fixing plate; a sampling spoon and an auxiliary sampling cover which can slide relative to each other are arranged on the guide mechanism, the auxiliary sampling cover is used for sealing the sampling spoon; a driving device is further arranged on the fixing plate and is used for controlling the sliding of the sampling spoon and/or the auxiliary sampling cover. The guide mechanism is arranged on the fixing plate, the sampling spoon and the auxiliary sampling cover are arranged on the guide mechanism, the driving device is further arranged on the fixing plate to drive the sampling spoon and/or the auxiliary sampling cover to move, so as to realize the opening and closing between the sampling spoon and the auxiliary sampling cover, therefore mechanical automatic weighing and sampling are realized, and the working intensity of an experimenter is reduced.

Description

technical field [0001] The invention relates to the field of experimental weighing equipment, in particular to a mechanical sampling spoon. Background technique [0002] In the field of coal sample experiment and pharmaceutical processing, it is necessary to weigh the sample before the experiment to obtain the quality data of the sample. The existing sample weighing and sampling device generally adopts a manually operated sampling spoon. During the weighing process, vibration is generated by tapping the medicine spoon with a finger, and the amount and speed of the addition amount can be grasped by controlling the force of the finger tapping. Due to the small amount of sample required in the experiment and high requirements for weighing accuracy, it is difficult to control the force of fingers, which often results in excessive addition, resulting in repeated weighing affecting the weighing speed and accuracy. On the other hand, because the existing sampling spoons are not se...
