Description

Plunger type feeding device

Technical Field

The utility model belongs to mineral sample experimental facilities field, concretely relates to plunger type feeder.

Background

When testing mineral samples, need the high-frequency to use many samples, all be artifical when all carrying out the feed to the sample at present and go on, inefficiency.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a plunger type feeder can realize the automatic micro-feed of high accuracy.

The utility model adopts the technical proposal that:

the utility model provides a plunger type feeder, is the blanking head of cavity including inside, be located the feeding axle in the cavity, be located feeding overhead and can drive the linear motion mechanism of feeding axle periodic lift and can drive the vibrating motor of linear motion mechanism and feeding head vibration simultaneously, the feeding head bottom is equipped with the discharge gate, the epaxial stirring piece that is equipped with of feed, the discharge gate is stopped up to the feeding axle when the superordinate, the bottom stretches out the discharge gate and can take the material out when the next.

Furthermore, a quantitative groove is arranged on the side surface near the upper part of the bottom end of the feeding shaft.

Preferably, the quantitative groove is a V-shaped groove.

Furthermore, the bottom end of the feeding shaft is an enlarged head, the upper part of the enlarged head is conical, the lower part of the enlarged head plugs the discharge hole when the feeding shaft is in an upper position, and the upper part of the enlarged head extends out of the discharge hole to form an annular space when the feeding shaft is in a lower position.

Further, the stirring member includes a flat plate provided on the feeding shaft and an inclined plate connected to the flat plate and facing downward.

Furthermore, the feeding head comprises a silo cover and a silo with a conical bottom, and the silo cover is sleeved on the silo and connected with the silo through bolts.

Further, the transmission tail end of the linear motion mechanism is connected with the feeding shaft through a coupler.

Preferably, the linear motion mechanism is a reciprocating electromagnet.

The utility model has the advantages that:

stirring piece can go up and down along with the feed axle, plays the stirring material effect, prevents that the material from gathering and building the canopy and not the unloading, and vibrating motor's effect makes the material gather in discharge gate department, and linear motion mechanism drive gives the periodic lift of material axle, and the lift can both carry out a dosing each time to realize the automatic micro-feed of high accuracy.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

As shown in fig. 1 and 2, in the first and second embodiments, the plunger-type feeding device includes a feeding head with a cavity inside, a feeding shaft 5 located in the cavity, a linear motion mechanism 1 located above the feeding head and capable of driving the feeding shaft 5 to periodically lift, and a vibration motor (not shown in the figure) capable of driving the linear motion mechanism 1 and the feeding head to vibrate simultaneously, wherein a discharging port is provided at the bottom end of the feeding head, a stirring member 6 is provided on the feeding shaft 5, the feeding shaft 5 blocks the discharging port in an upper position, and the bottom end extends out of the discharging port in a lower position and can take out the material. Stirring 6 can go up and down along with feeding shaft 5, plays the stirring material effect, prevents that the material from gathering and building the canopy and not the unloading, and vibrating motor's effect makes the material gather in discharge gate department, and linear motion mechanism 1 drive feeding shaft 5 is periodic goes up and down, goes up and down each time and can both carry out a dosing to realize the automatic micro-feed of high accuracy.

As shown in FIG. 1, in the first embodiment, a dosing groove 7 is formed in the side surface near the upper portion of the bottom end of the feeding shaft 5, so that dosing is guaranteed during each lifting and dropping, and the dosing groove 7 is preferably a V-shaped groove and is convenient to machine.

As shown in fig. 2, in the second embodiment, the bottom end of the feeding shaft 5 is an enlarged head 8, the upper part of the enlarged head 8 is tapered, the lower part of the enlarged head 8 blocks the discharge hole when the feeding shaft 5 is at the upper position, and the upper part of the enlarged head 8 extends out of the discharge hole to form an annular space when the feeding shaft 5 is at the lower position. The falling flow rate is controlled by controlling the clearance of the annular space during each feeding, and the feeding amount is controlled by controlling the time for forming the annular space.

As shown in fig. 1 and 2, in the first and second embodiments, the stirring member 6 includes a flat plate provided on the feeding shaft 5 and an inclined plate connected to the flat plate and directed downward.

As shown in fig. 1 and 2, in the first embodiment and the second embodiment, the feeding head comprises a silo cover 2 and a silo 4 with a conical bottom, and the silo cover 2 is sleeved on the silo 4 and is connected with the silo 4 through bolts.

As shown in fig. 1 and 2, in the first and second embodiments, the transmission end of the linear motion mechanism 1 is connected with the feeding shaft through the coupling 3.

In the first and second embodiments, the linear motion mechanism 1 is preferably an electromagnet that reciprocates.

It will be understood that modifications and variations can be made by persons skilled in the art in light of the above teachings and all such modifications and variations are considered to be within the scope of the invention as defined by the following claims.
