Abstract
The present invention relates to a kind of adjustable fixed than quantitative reduction device, including babinet, feed inlet and the first discharge port be connected with the feed inlet, the second discharge port, it is characterised in that：Further include middle control pendulum leaf and control device, feed inlet is divided into two by the middle control pendulum leaf, corresponds to first discharge port and the second discharge port respectively；The control device realizes that material guiding flows into the first discharge port or the second discharge port for control slew page rotation in controlling.The configuration of the present invention is simple, it is small, by controlling slew page in control in the dead time of a certain position, realize the fixed than quantitative division of material.
Description
Technical field
It is specific open a kind of adjustable fixed than quantitative reduction device the present invention relates to novel reduction device.
Background technology
In current combined sample making machine group or when sample preparation division, the reduction device used is common reduction device, such as
Spinning riffler, scraper reduction device, reciprocal reduction device etc.；Complicated, volume is big；And in various reduction devices, what majority used
It is manual regulative mode, division ratio is set by adjusting knob.Because using manually adjusting, adjustability difference and
Efficiency is low.
Invention content
The goal of the invention of the present invention is：It provides in order to solve the above problem a kind of simple in structure, small, automatically adjustable
Formula compares reduction device surely.
The technical solution adopted in the present invention is such：
It is a kind of adjustable fixed than quantitative reduction device, including babinet, feed inlet and the first discharging be connected with the feed inlet
Mouth, the second discharge port further include middle control pendulum leaf, control device and PLC, and feed inlet is divided into two by the middle control pendulum leaf, respectively
Corresponding first discharge port and the second discharge port；The control device realizes that material is oriented to for control slew page rotation in controlling
Flow into the first discharge port or the second discharge port；The PLC is for control device action and each part getting stuck described in programming Control
Time.
Further, the control device is one kind in cylinder, electric cylinders or hydraulic cylinder.
In conclusion due to the adoption of the above technical scheme, the beneficial effects of the invention are as follows：
The present invention is small, simple in structure, passes through the flexible and flexible dead time of PLC programming Controls wherein control device
Realize the rotation and its control in the dead time of some position of centering control slew page, that realizes material determine ratio, quantitative division,
And ratio can be adjusted arbitrarily.
Description of the drawings
Fig. 1 is the structural perspective of the present invention；
Fig. 2 is the structural side view of the present invention.
It is marked in figure：1, babinet；2, feed inlet；3, first charging aperture；4, second charging aperture；5, middle control slew page；6, it controls
Device.
Specific implementation mode
Invention is further described in detail with reference to the accompanying drawings and examples.
As shown in Figs. 1-2, a kind of adjustable fixed than quantitative reduction device, including babinet 1, feed inlet 2 and with the feed inlet 2
The first discharge port 3, the second discharge port 4 of conducting further include middle control pendulum leaf 5, control device 6 and PLC, and the middle control pendulum leaf 5 will
Feed inlet 2 is divided into two, and corresponds to first discharge port, 3 and second discharge port 4 respectively；
Stretching for the control device (can be cylinder, hydraulic cylinder, electric cylinders) is rotated for control slew page 5 in controlling, and is realized
Material guiding flows into the first discharge port 3 or the second discharge port 4；Rotary shaft is arranged in middle 5 both ends of control slew page, is erected at by rotary shaft
With on babinet 1, bearing is arranged with 1 junction of babinet in rotary shaft；One end of rotary shaft is extended, and (welding) integrated at this is set
Connecting rod is set, the function end of control device 6 is connect with connecting rod；The rotation of the flexible drive connecting rod of control device 6, in being further driven to
Control the rotation of slew page 5 (the rotation section of middle control slew page 5 forms fan-shaped, a such as Fig. 2).
The PLC is flexible for programming Control control device 6 and controls the stretching state dead time of control device 6 and retraction
The state dead time, (the flexible conversion of control device 6 was that material is flow into from first charging aperture 3 between second charging aperture 4 flows into
Conversion).
Operation principle：
Surely compare division：It is fixed than division to be realized by the time extended and retracted to control device 6, such as：Stretch out pause 2
Second, it retracts and pauses 1 second, then division ratio is：2：1.
Quantitative division：If supplied materials weight is m kilograms, need to take out n kilograms.
Set control device 6 one back and forth the working time as 3 seconds：Control device 6 stretches out the dead time for a；It retracts and pauses
Time is b.Then there are a+b=3, a/b=(m-n)/n that can calculate the value of a and b；Realize quantitative division.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement etc., should all be included in the protection scope of the present invention made by within refreshing and principle.
Claims (2)
