In order to make those skilled in the art more fully understand the present invention program, with reference to the accompanying drawing and it is embodied
The present invention is described in further detail for mode.
Please refer to figs. 1 to 4, and wherein Fig. 1 is the front view of mechanical sampling device provided by the embodiment of the present invention, Fig. 2
For the top view of mechanical sampling device in Fig. 1, Fig. 3 is the structural schematic diagram of probe tube in Fig. 1, and Fig. 4 is provided by the present embodiment
Mixing part structural schematic diagram.
In the first specific embodiment, mechanical sampling device includes that rack 6 crucible 5 is arranged and upside are set
There are opening, downside to be equipped with the barrel 1 to hold sample powder of through-hole, barrel 1 is connected with the driving section being set in rack 6,
By the drive of driving section to realize the movement of barrel 1 in the vertical direction relative to rack 6, it is equipped with and earthenware in the lower section of barrel 1
The probe tube 2 that crucible 5 is connected, when driving section drives barrel 1 to move down with respect to rack 6, probe tube 2 is from the downside of barrel 1
Through-hole enters in barrel 1, the extraction to the sample powder in barrel 1 is realized by probe tube 2, and via 2 sample of probe tube
Powder is fallen into crucible 5.
It should be noted that in the present embodiment, such as crucible 5 is intended only as containing the single thing of instrument in laboratory
Example does not represent the present embodiment and is only capable of this kind of function of containing instrument and realize the mechanical sampling device by crucible 5, for it
His those skilled in the art can be by easily replacing and obtaining the component and mode of same beneficial effect, with should belong to this reality
Apply the declared range of example.This is also only only belonged to likewise, pouring into for sample powder from above in the upside of barrel 1 setting opening
The a kind of of embodiment illustrates example, for barrel 1 other positions or use other modes to realize the loading of sample powder,
With the declared range that should belong to the present embodiment.
In the present embodiment, driving section specifically includes rotating electric machine 7, screw rod 8, guide rail 9 and guide post 10, rotating electric machine 7
It is set up directly in rack 6, in the top of rotating electric machine 7, screw rod 8 is arranged along the vertical direction and its bottom is socketed in rotating electric machine
7 output end, guide post 10 are located in rack 6, and the axis of guide post 10 is located among the axis of rotating electric machine 7 and barrel 1, is leading

The upside of body is equipped with the probe tube suction nozzle in cone, the tip institute of probe tube suction nozzle when sampling in tube body insertion barrel 1
The horizontal cross-section for the sample powder being located at is to sample section, and probe tube 2 is by probe tube suction nozzle to the tip of probe tube suction nozzle
The sample powder in the sampling section being located at is sampled.In view of sample powder has the granularity of 0.2mm, probe tube is inhaled
The requirement for enabling to sample powder to enter should be met to extract the diameter minimum of the sampling hole of sample powder in head, as tool
Body ought to be changed using the probe tube suction nozzle of which kind of size according to the sampling requirement in laboratory, but should belong to the present embodiment together
Declared range.
In another specific embodiment, mechanical sampling device provided by the present embodiment further includes being set to rack 6
On tripod 3, tripod 3 be located at the lower section of feeding cylinder 1 and be equipped with for sample tube body inlay card hole slot, tripod 3
The arch that downside is equipped with to place crucible 5 supports, and the central axes of barrel 1, probe tube 2 and crucible 5 are on same straight line, arch
Shape support is detachably connected to realize the taking-up after the loading and completion sampling when crucible 5 is in sampling with tripod 3.Except this with
Outside, further include the vibrator 4 being located on the side wall of tripod 3, and before being sampled, top be sticked in opening for barrel 1
The blender 12 of the stirring to the sample powder in barrel 1 is realized at mouthful and by the epitaxial raised of lower part.It should be noted that
Blender 12, which can be, to carry out carrying out Stirring to the outer edge bulge control of its underpart by the way of electronic, is also possible to adopt
The manually extension axis shared by the outer edge bulge setting to lower part, is realized by way of manual rotation's extension axis
Stirring of the blender 12 to the sample powder in barrel 1, but which kind of mode no matter is used, should belong to this implementation together illustrates model
It encloses.
In the present embodiment, sample powder imports the dress of mechanical sampling provided by the present embodiment from the container that script loads
In the barrel 1 set, the top of blender 12 is sticked in the opening of barrel 1 and by electric or hand mode, to barrel 1
In sample powder carry out the stirrings of different rotation rates, different rotary mode and different rotary direction, in complete paired samples
It after the uniform stirring of powder, takes out blender 12 and opens rotating electric machine 7, rotating electric machine 7 drives the screw rod 8 being attached thereto around certainly
The rotation of body rotary shaft, be socketed on guide post 10 to be only capable of the guide rail 9 to move up and down relative to guide post 10 along vertical axis by
For first end and screw rod 8 in horizontal direction by the mating connection of male and female screw thread, guide rail 9 converts the rotary power on screw rod 8 to
Along the straight line power of the vertical axis of guide post 10, drive the connected barrel 1 of second end opposite in the drive lower guideway 9 of straight line power
Rack 6 moves straight down, when barrel 1 moves downward so that the fitting into barrel 1 from the through-hole of 1 bottom of barrel of probe tube 2
When height, rotating electric machine 7 stops outside output power, opens vibrator 4 and drives tripod 3 and dress by vibrator 4
It is vibrated with the probe tube 2 of tripod 3, sample powder is got enter into probe tube 2, is entered in probe tube 2 under gravity
Sample powder fall into crucible 5, extraction and collection of the crucible 5 for sample powder are completed, in the extraction for completing sample powder
Afterwards, it closes vibrator 4 and controls rotating electric machine 7 and export opposite rotational power outward, under the drive of the rotary power, screw rod
8 are further driven to guide rail 9 moves upwards on vertical axis along guide post 10, and barrel 1 is able to move to the direction far from probe tube 2
And final probe tube 2 is extracted from the through-hole of 1 downside of barrel, when needing to carry out the sampling and chemical examination of other indexs, in repetition
It states step and re-starts sampling.
For superior technique effect, run through in the lower part of arch support and be equipped with air valve 11, after sampling and by earthenware
Crucible 5 is opened the air pressure switch of air valve 11, is purged by air valve 11 to probe tube 2 after taking out in arch support
And cleaning, record of the specific set-up mode during refer to the prior art for air valve 11 for air valve 11, herein no longer
It repeats one by one.
It should be noted that barrel 1 is to be detachably connected, and the crucible 5 being placed in arch support can also basis with guide rail 9
It needs to be removed or placed into, in the lab in view of the requirement of convenience and different size, generally requires to adopt one or many
Using the barrel 1 and crucible 5 to quantity more than one in sample, although only giving a barrel 1 and one in the present embodiment
The explanation of crucible 5, but for being taken out original barrel 1 and/or crucible 5 and being packed into new barrel 1 and/or crucible 5, even if
Barrel 1 and/or crucible 5 have converted shape and/or specification, with the declared range that should belong to the present embodiment.
It should be noted that in the present specification, such as first and second etc relational terms are used merely to one
Entity is distinguished with other several entities, and without necessarily requiring or implying between these entities, there are any this actual
Relationship or sequence.
