Abstract
The utility model provides the dosing device of orthopaedic quantification and measurement. A stockhouse is arranged on a frame, and the discharge port of the lower part of the stockhouse is provided with a spiral gate mechanism. A handwheel is rotated, and racks on the gate can be moved along gear wheels to open and close the gate. The lower part of the stockhouse is provided with a computer belt balance whose sensor can automatically control the belt speed to keep the flow capacity a constant value and to improve the proportioning precision. The utility model is used for construction proportioning work such as roads, squares, etc.
Description
The utility model relates to a kind of aggregate measuring fixed amount batching set-up, be used for accurate quantification metering after, the usefulness of preparing burden belongs to the technical field of engineering machinery.
Aspect the construction on highway, urban road, airport and square, all use sub-surface stabilizing material plant mix equipment, its aggregate all adopts the volume metering mode, it is exactly the area of opening according to the feed bin door (Lift * door width), estimate its output (ton/hour) with the product of belt feeder belt speed, this metering method precision is very low, and error is bigger, influence construction quality unavoidably, and can not align at any time.
The purpose of this utility model is that a kind of aggregate measuring fixed amount batching set-up will be provided, and it can overcome above-mentioned deficiency.
The purpose of this utility model is to realize like this, the taper feed bin is contained in above the frame, discharging opening is arranged at the feed bin bottom, spiral gate mechanism is housed, the computer belt conveyer scale is housed below the feed bin, its load sensor and belt speed sensor interknit, and can control the flow that belt speed guarantees aggregate automatically is a constant, and trueness error is less than 10%.The proportioning and the construction quality of batching have been guaranteed.
Fig. 1 aggregate measuring fixed amount batching set-up
The B of Fig. 2 accompanying drawing 1 is to view
Spiral gate structural scheme of mechanism on Fig. 3 feed bin discharging opening
The side view of Fig. 4 gate mechanism
The A-A of Fig. 5 accompanying drawing 3 schemes to the part
Now in conjunction with the accompanying drawings the structure of aggregate measuring fixed amount batching set-up is described in detail: frame (3) is synthetic by channel-section steel and 8 diagonal brace angle steel soldering group of the channel-section steel of 4 settings and 4 lines, the channel-section steel bottom is welded with base anchor, can be fixed on above the basis with foot bolt, the feed bin of taper (1) is welded into steel plate, feed bin (1) is contained in above the frame, the major part of feed bin (1) is positioned at frame (2), feed bin (1) discharging opening below, spiral gate mechanism is housed, rotate its handwheel (7), so the gear shaft (8) that links to each other with handwheel (7) rotates thereupon, just can close or starting gate (11), the computer belt conveyer scale is equipped with in the lower end of feed bin (1), and its model is that BSM-II type (belongs to known technology, therefore will not describe in detail), the support of computer belt conveyer scale (6) is fixed on above the basis with foot bolt.
Fig. 2 be the B of accompanying drawing 1 to view, feed bin (1) is positioned in the middle of the frame (2), feed bin (1) discharging opening is equipped with spiral gate mechanism in the side of bottom, the computer belt conveyer scale is equipped with in feed bin (1) below.
Fig. 3 is a feed bin discharging opening spiral gate structural scheme of mechanism, handwheel (7) is connected with axle (8), be contained in the bearing bracket stand (13), bearing bracket stand (13) is with screw (14), nut (15), packing ring (16) is fixed on above the feed bin (1), 2 gears (9) and two tooth bars (10) engagement are arranged on the axle (8) of handwheel (7), tooth bar (10) is fixed on above the gate (11), the both sides of gate (11) are contained in the track (12), when rotating handwheel (7), axle (8) cog (9) also rotate thereupon, because the position of bearing bracket stand (13) is fixed, so tooth bar (10) can move up and down, thereby gate (11) is moved up and down along track (12), make gate play the effect of opening or closing discharging opening.Track (12) screw (17), nut (18) packing ring (19) is fixed on above the feed bin (1).
Fig. 4 is the side view of Fig. 3 gate mechanism, track (13) screw (14), nut (15), and packing ring (16) is fixed on above the gate (11).
Fig. 5 is that A-A schemes to the part in the accompanying drawing 3, on the axle (8) gear (9) is housed and is meshed with tooth bar (10).
After the gate (11) of feed bin (1) is opened, gate just maintains static, and by computer balance continuous and quantitative weighing automatically, connect each other according to the load sensor and the speed pickup that are contained on the computer belt conveyer scale support, the belt speed of control belt conveyer scale, when the material amount of discharging more after a little while, belt speed is speeded, more for a long time, belt speed is slowed down in the material amount, the flow that remains aggregate like this is a constant, make stability of flow accurate, the feed proportioning system of being made up of several these devices like this can be with the aggregate of various different sizes, according to the requirement of different proportionings, finish accurate batching.Can fully guarantee the measuring accuracy and the distributing precision of aggregate.
Compared with prior art, quantitative measuring burden apparatus for orthopaedics has following advantage:
1, adopt computerized belt conveyer scale, interrelated by its Control System of Microcomputer and the load sensor and the velocity sensor that are contained on the scale frame, can the automatic adjustment belt speed, make the aggregate flow keep constant.
2, the measuring accuracy error is less than 1%.
3, this scale working stability is easy and simple to handle, and production efficiency height, hourly output can reach 200 tons.
Claims (2)
1, a kind of aggregate measuring fixed amount batching set-up, it is characterized in that taper feed bin (1) is contained on the frame (2), major part is positioned at frame (2), feed bin (1) discharging opening is equipped with spiral gate mechanism, the computer belt conveyer scale is equipped with in feed bin (1) lower end, and the support of belt conveyer scale (6) is fixed on above the basis with foot bolt.
2, batching set-up according to claim 1, the handwheel (7) that it is characterized in that spiral gate mechanism is connected with one (8), be contained in the bearing bracket stand (13), 2 gears (9) and tooth bar (10) engagement that is fixed on the gate are arranged on the axle (8), track is equipped with in the gate both sides.
