Specific embodiment
To further illustrate the technical scheme of the present invention below with reference to the accompanying drawings and specific embodiments.
As shown in figures 1-4, the present embodiment provides a kind of distributing device, which includes feed bin 1, rotary shaft 2, driving dress
Set, tripper 3 and feed arm 4, the top of feed bin 1 are equipped with opening 11, material is added in feed bin 1 by opening 11, feed bin 1
Bottom plate 13 is equipped with discharge port 12；Rotary shaft 2 is arranged in discharge port 12；Driving device is for driving rotary shaft 2 to rotate；Sub-material
Device 3 covers at discharge port 12 and can cover discharge port 12, and gap 5 is equipped between tripper 3 and bottom plate 13, tripper 3
Bottom is equipped with groove 31, and groove 31 is horizontally extending；Feed arm 4 is located in gap 5, and feed arm 4 includes first end and the
Two ends, first end are fixed in rotary shaft 2, second end adjacent to feed bin 1 inner wall, feed arm 4 be used for by material from second end to
First end scrapes.
It is understood that when in use, be added to the material in feed bin 1 and be located between 1 inner wall of tripper 3 and feed bin,
The bottom that discharge port 12 is covered by tripper 3, prevents material from being fallen by discharge port 12, while 4 feed bin 1 of arm will be fed,
Feed arm 4 can scrape the material being in contact with it when rotating from the inner wall of feed bin 1 to the direction of discharge port 12, and material can be with
It is flowed out from discharge port 12, ensure that 1 bottom of feed bin will not be accumulated far from the material at discharge port 12, and ensure that the equal of discharging
Even property, by being fed 4 continuous rotation of arm, material is successively reduced in feed bin 1, can guarantee the continuity and stability of discharging,
To ensure the made representativeness for taking sample.
If there are the irregular material of partial shape, such as elongated material in material, length is greater than the ruler in gap 5
It is very little, when the elongated material material is erected in feed bin 1, gap 5 can not be forced through by scraper, and then can not be into
Enter into discharge port 12, the present embodiment is by being arranged groove 31 in the bottom of tripper 3, when scraper pushes the elongated material to pass through
When groove 31, if the length of the elongated material is less than the groove depth of groove 31, it will in into groove 31 and enter discharge port
In 12, it is further ensured that the made representativeness for taking sample.
Optionally, tripper 3 in cone, and its bore bottom one end with respect to cone one end close to discharge port 12.Tool
Body, the aperture of discharge port 12 is less than the diameter of 3 conical lower portion one end of tripper in the present embodiment, so that tripper 3 can incite somebody to action
Discharge port 12 covers, and be located at the gravity of material right above discharge port 12 on tripper 3, make discharge port 12 there are
Enough spaces guarantee that material falls, while sharing the pressure of a part of material by tripper 3, can also reduce material to feed
The pressure of arm 4, and the resistance when feed rotation of arm 4, guarantee the feed smooth rotation of arm 4.
The angle of repose of material is α, and the side wall of tripper 3 and the angle of horizontal plane are the α of 1.0 α~2.0.Angle of repose is also known as stopped
Only angle refers to that material is able to maintain the maximum angle of natural stability state, the i.e. angle on the unilateral opposite ground of material heap when stacking,
Heap adds this bulk cargo after this angle is formed, then up, will slide down naturally, keeps this angle, and material heap can only increase, together
Shi Jia great floor space.Make the side wall of tripper 3 and the angle α of 1.0 α~2.0 of horizontal plane, material accumulation or attachment can be prevented
On the surface of tripper 3.
The nominal particle size of material is d, and nominal particle size is also referred to as used as nominal maximum particle size, is referred to accumulative with oversize (material)
Quality percentage is closest but is not more than the 5% corresponding screen size of sieve.Between 3 lower edge of tripper and discharge port 12
Horizontal distance is L1,1.5d≤L1≤2.5d, preferred L1=2.2d, vertical between 3 lower edge of tripper and discharge port 12
Distance is L2,1.0d≤L2≤1.5d, preferred L2=1.1d.In view of the angle of repose of material, by making L1 be about L2's
Twice, feed arm 4 can be effectively prevented when not rotating, material is fallen in discharge port 12 from gap 5.
Optionally, tripper 3 is shell, and bottom is equipped with opening 11, and groove 31 runs through the both ends of 3 side wall of tripper, from
And material is by that can push free movement by feed arm 4 after groove 31.In the present embodiment, the width of rebate of groove 31 is L3,
1.5d≤L3≤2.0d, the depth capacity of groove 31 are L4,1.5d≤L4≤2.0d.The longitudinal section of groove 31 is arc-shaped.When
So, the present embodiment for groove 31 concrete shape without limitation.
It is understood that the quantity of groove 31 may be set to be multiple, and multiple grooves 31 are along the axis of tripper 3
Line is angularly arranged.
It is fed arm 4 in the shape of a spiral, cross section is helically linear, so that being fed arm 4 can be by position during scraping
In 1 bottom of feed bin and far from the material at discharge port 12 to being pushed at discharge port 12；It is fed one end and the bottom plate of 4 bottom of arm
13 upper surface fitting can prevent from being located at so that being fed arm 4 can scrape the material for being located at 1 bottom of feed bin to discharge port 12
Material accumulation at 1 bottom of feed bin and separate discharge port 12.It is fed arm 4 for each revolution, will will be located at the one of 1 bottom of feed bin
Layer material is scraped to discharge port 12 and is flowed out, and can also be loosened the material scraper for being located at 4 top of feed arm, especially when material contains
When water rate is higher, it can prevent material from leading to the uniformity for influencing to discharge because squeezing compacting.Continuous with feed arm 4 turns
It is dynamic, it is ensured that material continuously, uniformly, is steadily flowed out from discharge port 12.
Optionally, the height of feed arm 4 is in the trend that becomes smaller from first end to second end, to be fed the height of 4 second end of arm
