Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.

It should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" are intended to be construed broadly, as if they were connected either fixedly or removably, or as integrally formed structures. To those of ordinary skill in the art, the specific meaning of such terms in this patent may be understood as appropriate.

The invention also provides a preferred embodiment

As shown in fig. 1 and 2, the medicine metering device designed by the present invention includes a medicine barrel 1, a metering mechanism 2, a lower medicine barrel 3 and a reset mechanism 4.

Referring to fig. 1, 2, 3 and 4, a medicine storage cavity is provided in the medicine barrel 1 for storing preventive medicine or other fluid dispersing particles; the inner wall of the medicine barrel 1 can be provided with scale marks, and when dangerous fire medicine is contained in the rice, the stored medicine amount can be reasonably controlled according to the scale marks. The metering mechanism 2 comprises a metering plate 21, a medicine quantity fine adjustment plate 22 and an adjusting piece 23; the metering plate 21 is arranged at the bottom of the medicament barrel 1, and a metering groove 21a which is communicated with the medicament storage cavity and extends to one side of the metering plate 21 is formed in the plate surface; the drug quantity fine adjustment plate 22 is slidably disposed in the measuring tank 21 a. The adjusting member 23 is connected to the dose fine adjustment plate 22, and is used for driving the dose fine adjustment plate 22 to move so as to adjust the size of the metering slot 21a, thereby adjusting the weighing range of the medicament, and the controllability is higher, for example, controlling the medicament to be weighed to 100 mg to 105 mg. The lower barrel 3 is disposed right below the measuring groove 21a, and the lower barrel 3 has a tapered structure with a downward discharge port, so that the medicine can be conveniently discharged. Reset mechanism 4 links to each other with regulating part 23 for drive regulating part 23 and so that make quantity fine-tuning board 22 reset, drive regulating part 23 through reset mechanism 4 after the measurement finishes and reset, thereby interrupt the transport of liquid medicine, whole measurement process has avoided medicament and human direct contact, the corresponding promotion of security.

In the present embodiment, as shown in fig. 5 and 6, the return mechanism 4 includes a return lever 41, a return seat 42, and a return spring 43; the reset rod 41 is slidably inserted into the reset seat 42, and the reset spring 43 is disposed in the reset seat 42 and connected to the reset rod 41. Because the medicament metering in-process, the clearance of jam metering plate 21 and dose fine-tuning board 22 may appear in the large granule medicament, in case when operating personnel adjusts dose fine-tuning board 22 in hard too violently and extrude the easy condition that the burning appears of medicament, support release link 41 and reset seat 42 through adopting reset spring 43, guarantee the condition that dose fine-tuning board 22 pulling in-process can not appear steeply, dose fine-tuning board 22 removes more steadily, avoid because of drawing the too big risk that causes the accident of power of medicine by force. In order to further limit the adjustment range of the drug quantity fine adjustment plate 22, a step guide groove matched with the reset rod 41 is arranged in the reset seat 42; the one end that the release link 41 is located in the reset seat 42 still is provided with stopper 411, and the maximum length of movement that the release link 41 removed along the reset seat 42 is restricted through the stopper 411 that sets up, avoids the situation that fine adjustment plate 22 of the dose was excessively pulled.

In this embodiment, as shown in fig. 3 and 4, the adjusting member 23 includes a fine adjustment screw 231 and an adjusting plate 232, the adjusting plate 232 is connected to the fine adjustment plate 22 of the dosage through the fine adjustment screw 231, and the fine adjustment screw 231 is used to fine adjust the position of the fine adjustment plate 22 of the dosage, so as to effectively adjust the adjustable range of the metering slot 21a reasonably for the medicaments of different specifications.

In this embodiment, the medicament barrel 1 is of a stainless steel or super-hard aluminum alloy structure, thereby avoiding accidents caused by static electricity generated in the medicament metering process. The drug quantity fine adjustment plate 22 is made of tin bronze, so that the drug quantity fine adjustment plate 22 is ensured to have higher wear resistance. In addition, a plurality of electrostatic discharge mouths are still reserved to 1 outside of medicament bucket, and every electrostatic discharge mouth all is connected with electrically conductive bracelet, and in the measurement process, the electrically conductive bracelet of user's accessible releases static in advance, avoids causing the gunpowder burning because of static.

The working process of the invention is as follows:

firstly, operating personnel need wear the electrically conductive bracelet and get rid of static to the inside wall to medicament bucket 1 cleans, then according to the specification of required measurement medicament toward medicament bucket 1 internal filling appropriate dose's medicament, accomplish the preliminary preparation work of medicament measurement promptly.

Then, during the metering process, the user adjusts the fine adjustment screw 231 in advance to adjust the fine adjustment plate 22 to a proper position. Then pulling regulating plate 232 and driving the fine adjustment board of amount of medicine 22 and slide along adjusting the measuring groove 21a for adjust measuring groove 21a and be opened gradually, the medicament follows medicament bucket 1 and follows the dropping of adjusting measuring groove 21a to feed cylinder 3 and derive, after weighing the medicament of a certain dosage, the operator can loosen regulating plate 232, under reset spring 43's drive, drives fine adjustment board of amount of medicine 22 playback, can accomplish a measurement work.

Finally, the continuous metering operation of the medicament can be realized by repeating the procedures, and the efficiency is higher.

It should be noted that the medicine metering device provided by the present invention can be used not only as a metering mechanism alone, but also as a metering mechanism of an automatic medicine drawer or an automatic weighing system, so as to realize automatic weighing.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
