Description

Full-automatic sampler

The utility model relates to a kind of sampling conveying equipment.

At present, domestic production cement producer uses hand sampling more when the analytical test sample, send the laboratory to carry out analytical test, and it is time-consuming not only to require great effort, and causes sample randomness poor, lacks representativeness, thereby makes production management and quality management all compare difficulty; And introducing equipment all is a Robot actions, and complex structure costs an arm and a leg.

The purpose of this utility model is to remedy the deficiencies in the prior art, provides a kind of and is convenient to make, price is lower, collection sample mixed, division, shoot and carry the full-automatic sampler into one, full process automatization.

The purpose of this utility model is achieved through the following technical measures:

A kind of full-automatic sampler is characterized in that it is made up of mixing chamber, measuring hoper, storage bin, bolt action and conveying mechanism.Mixing chamber and sampling head are communicated with, with bearing fixing the end of on, mixing chamber has on a bottom that has cushion and a trundle is pressed at the bottom of the mixing chamber, bottom has a seal closure outward, bottom is connected with motor by bearing with seal closure, motor is fixed on the seal closure outer side center, seal closure is hung on housing by hanging axis, can rotate along axle, bottom can be stirred mixing chamber and sampling head coaxial rotation by trundle under driven by motor, the seal closure outside also is connected with Vib. with electromagnet by pull bar, and the lower end is a measuring hoper, the both sides of measuring hoper are provided with waste outlet, mixing chamber, seal closure, the measuring hoper motor, electromagnet and Vib. are contained in the housing; Discharging opening exposes housing, discharging muzzle one flexible pipe stretches in the conduit, conduit passes the storage bin outer cover and stretches in the storage bin, conduit is fixed on the storage bin outer cover end face, the storage bin outer cover is fixed on the top board of bolt action, and the storage bin in the storage bin outer cover is hung on cone valve, and cone valve is fixed on outer cover end face center and passes storage bin, the storage bin outlet is pressed on the cone, and holddown spring and vibrator coil are arranged between storage bin end face and outer cover; Bolt action is between top board and base plate by three shore supports, comprise central shaft, rotating disk and magazine holder, central shaft is connected with the motor that drives dial rotation, screw mandrel is housed on the rotating disk, screw, screw mandrel and motor join, screw upper end and magazine holder are gone to the bottom and are fixed together, can promote the magazine holder along slide rail when screw mandrel rotates moves up and down, the magazine holder is a tubular bend pipe, the one end magazine of packing into, the other end with breathe the air port and be connected, can between charging door on the top board and delivery port, change with rotating disk, and can move up and down, magazine divides lid and box body, and lid is by moving valve, spring and support are formed, when the moving valve pressurized, then the caping periphery slit occurs so that pressure is removed in charging, and spring recovers moving valve is stopped up the slit again; Conveying mechanism comprises blower fan and supporting with it vacuum pressure valve, vacuum pressure valve has valve body, valve block and interlock axostylus axostyle, electromagnet is formed, four road thresholdings are arranged in the valve body, thresholding is divided into three equally spaced intervals to valve body, an air port is arranged on each interval wall, middle air port is for breathing the air port, join with the magazine holder, two other air port respectively with the advancing of blower fan, air outlet joins, and the valve body two ends respectively have an air port to communicate with atmosphere, in three intervals, respectively there is a valve block in two intervals, both sides, two valve blocks are with interval equidistant, and serial connection is fixed on the interlock axostylus axostyle, during the moving interlock of string axostylus axostyle, valve block compresses alternate twice thresholding respectively, interlock axostylus axostyle one end is driven by electromagnet, and the other end connects spring, valve block can be in interval move left and right.

Mixing chamber also can be designed to be interlocked by two bowl bodies and form, the bowl edge connects finger by three and passes, and by spring two bowl bodies is become an airtight bin, and the driven by motor bin rotates, electromagnet is inhaled one of moving two bowl bodies, and the bowl body is just opened so that blowing to the left or to the right along connecting finger.

Vacuum pressure valve also can be designed to be made up of valve body, valve block, screw mandrel, motor, is rotated by screw mandrel to cause valve block move left and right on screw mandrel, blocks respective threshold.In addition, vacuum pressure valve can replace with two typhoon machines.

Bolt action also can be designed to have screw mandrel, screw simultaneously on the central shaft by driven by motor, when central shaft rotates, the magazine holder promotes and descends, when dropping to lowest order, can forward the magazine holder under the delivery port to by charging door, or forward under the charging door by delivery port.

During work, the material that is taken out by sampling head evenly mixes material by the not stall of mixing chamber is moving in mixing chamber, and the sample interval is set in advance.When arriving the stipulated time, electromagnet is inhaled moving, affect seal closure when hanging axis rotates an angle by pull bar, bottom lower edge and mixing chamber leave a slit, and material flows into measuring hoper, unnecessary material is flowed out by waste outlet, affect seal closure that measuring hoper discharging mouth and conduit are subjected to displacement simultaneously, press off rubber hose, thereby sealed funnel discharging mouth, after material goes out only, the electromagnet outage, bottom and funnel discharging mouth all can arrive original position, and flexible pipe recovers, funnel discharging mouth and conduit are connected, at this moment, Vib. begins vibration, with the material storage bin of packing into, again the material in the storage bin is packed in the magazine, as the running sample of a round of visits; When material shoots box, the driven by motor central shaft rotates counterclockwise, with the magazine holder by forwarding under the delivery port below the charging door, screw mandrel is rotated by driven by motor, screw promotes the magazine holder upwards along slide rail, move on the storage bin pushing away and promote on the magazine in the magazine holder, make the cone valve cone that compresses the storage bin outlet leave outlet, the moving valve that the magazine of cone valve cone compressing simultaneously covers, caping exposes the space, vibrator coil begins vibration, material enters in the magazine by storage bin discharging opening and lid gap, motor reverses again, magazine moves down and can arrive original position, storage bin is pushed down cone valve again, moving valve on the lid is because spring recovers to block again the space, at this moment rotating disk clockwise rotates, magazine is gone back under the delivery port, the positive handle magazine of driven by motor screw mandrel upwards pushes delivery pipe, at this moment pipeline opening is blocked in magazine holder upper edge makes magazine holder and pipeline airtight, the breathing mouth of pipe of vacuum pressure valve is presented the wind state, open the blower fan air-supply then, magazine is delivered to the destination by delivery pipe, behind the taking-up material, magazine is put back to pipeline, at this moment breathing valve block moves to make and breathes the mouth of pipe and be the state of bleeding, magazine is sucked back the magazine holder, whole mixing, division, shoot, transportation finishes, and waits for next circulation.

The utility model collection sample mixed, division, shoot and carry to one, realized the robotization of overall process, and be convenient to make, cost is lower.
