Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 2, for the utility model discloses a powder feed arrangement of concrete mixing plant, including hopper body 1, hopper body 1's lateral wall upper end intercommunication has feed inlet 11, and there is discharge gate 12 bottom hopper body 1, and discharge gate 12 is opened by control mechanism 8 control, and hopper body 1 gathers together to discharge gate 12 for cylindric and bottom, refers to fig. 4, has pivoted commentaries on classics storehouse 2 in hopper body 1.

Referring to fig. 3, the control mechanism 8 includes an arc-shaped baffle 81, the arc-shaped edges on both sides of the baffle 81 extend out of connecting plates 85, the connecting plates 85 are located on both sides of the hopper body 1, the top of the connecting plates 85 fixedly extends out of the supporting rod 82, the outer side wall of the hopper body 1 is rotatably connected with a pair of connecting shafts 83 which are symmetrical about the axis of the hopper body 1, and the end portions of the supporting rods 82 are fixed with the connecting shafts 83. A hydraulic cylinder 84 is arranged on the outer side wall of the hopper body 1 above the straight line edge of the baffle 81, one end of the hydraulic cylinder 84 is hinged to the hopper body 1, and the output end of the hydraulic cylinder is rotatably connected to the straight line edge of the baffle 81.

When the discharge port 12 is opened for discharging, the output end of the hydraulic cylinder 84 retracts, the baffle plate 81 and the support rod 82 are pulled to rotate by taking the connecting shaft 83 as the axis, so that the discharge port 12 is exposed, and the powder slides out of the hopper body 11; when the discharge port 12 is closed, the output end of the hydraulic cylinder 84 is extended to push the shutter 81 to rotate, covering the discharge port 12.

Referring to fig. 4, the rotary bin 2 is closely attached to the inner wall of the hopper body 1, has the same shape as the hopper body 1, and includes an inlet 21 and an outlet 22. The topside of rotary bin 2 is less than feed inlet 11 to the lateral wall of rotary bin 2 is smooth with the inside wall contact surface of hopper body 1, makes rotary bin 2 when hopper body 1 internal rotation, and is more smooth and easy. The inner wall of the hopper body 1 is provided with a groove 13 which is sunken in the inner wall, the rotary bin 2 is clamped in the groove 13 (refer to fig. 5), and the top surface of the rotary bin 2 is a slope which inclines towards the center of the rotary bin 2, so that powder added from the feed inlet 11 is easy to slide into the rotary bin 2 when the rotary bin 2 rotates, and the possibility that the powder enters from a gap between the rotary bin 2 and the side wall of the hopper body 1 is reduced.

The top of the rotary bin 2 is fixed with a plurality of connecting rods 3, and the connecting rods 3 extend to the center of the top of the hopper body 1. The top surface of hopper body 1 is fixed with motor 4, and the output of motor 4 is connected with axis of rotation 5, and axis of rotation 5 runs through the top surface of hopper body 1 and stretches into inside the hopper body 1. The end of the rotating shaft 5 is fixed to the connecting rod 3. So that when the motor 4 is started, the rotating shaft 5 drives the connecting rod 3 and the rotary bin 2 to rotate.

Referring to fig. 4 and 6, a plurality of guide plates 6 are fixed on the inner side wall of the rotary bin 2, the guide plates 6 extend from the inlet 21 of the rotary bin 2 to the outlet 22 of the rotary bin, and the guide plates 6 gather towards the center of the rotary bin 2, so that one side of each guide plate 6, which is far away from the rotary bin 2, is close to the central axis of the rotary bin 2, one side of each guide plate 6, which is close to the axis of the hopper body 1, extends to the upper part of the discharge port 12, the guide plates 6 are inclined, and the inclined direction of each guide plate and the axis direction of the rotary bin. Therefore, the diversion plate 6 divides the rotary bin 2 into a plurality of compartments, so that the powder is divided into a plurality of small parts, and the large block accumulation is avoided.

The powder is added into the rotary bin 2 from the feed inlet 11, namely the powder is added into the rotary bin 2 from the edge of the rotary bin 2, when the rotary bin 2 rotates, the powder flows into the space between two adjacent guide plates 6, and along with the rotation of the rotary bin 2, the powder slides out from the outlet 22 along the side wall of the rotary bin 2. Therefore, the powder enters the rotary bin 2 in batches, the possibility of blockage is reduced, and the inclined guide plate 6 prevents the powder from being smashed into the rotary bin 2 vertically to be stacked and compacted, so that the inclined guide plate 6 enables the powder to be stacked slowly and the stacked powder is loose.

If the discharge port 12 is closed, the feed port 11 is filled with a large amount of powder, and the powder starts to be accumulated upward from the discharge port 12. If need the ejection of compact, open discharge gate 12, a part of powder is discharged from discharge gate 12, motor 4 drives rotary bin 2 and slowly rotates, the edge that guide plate 6 is close to discharge gate 12 at this moment promotes the powder that piles up above discharge gate 12, exert the driving force to accumulational powder, make the powder that lies in discharge gate 12 top in rotary bin 2 dredge, after the powder that lies in piling up above discharge gate 12 in rotary bin 2 discharges from discharge gate 12, the powder between guide plate 6 receives gravity and slides down along the inner wall of rotary bin 2, slide to the export 22 of rotary bin 2, and discharge from discharge gate 12. The powder accumulated in the discharge port 12 is movably dredged, and the powder in the storage bin body 1 can easily slide out of the discharge port 12.

A screen 7 is arranged in a feed inlet 11 connected with the hopper body 1, and when powder is fed into the hopper body 1 from the feed inlet 11 at a high speed, the powder firstly passes through the screen 7. When powder with a certain speed passes through the screen 7, the powder directly impacts the screen 7, so that the agglomerated powder is scattered, and the scattered powder enters the hopper body 1 and is not easy to agglomerate and accumulate again.

The implementation principle of the embodiment is as follows: the powder is added into the hopper body 1 from the feed inlet 11 at a high speed, and the agglomerated powder is scattered through the screening of the screen 7, and the powder slides into the hopper body 1 along the slope-shaped top surface of the rotary bin 2. The motor 4 drives the rotary bin 2 to rotate, and the powder enters between two adjacent guide plates 6 and is introduced into the discharge hole 12 along the rotating guide plates 6. When the discharge port 12 is opened at this time, the powder is discharged directly from the discharge port 12. When the discharge port 12 is closed, the feeding port 11 is continuously fed, and powder in the rotary bin 2 is accumulated.

During discharging, the hydraulic cylinder 84 is started, the output end of the hydraulic cylinder 84 retracts, the baffle 81 is pulled to rotate along the axis of the connecting shaft 83, the discharge port 12 is exposed, the rotary bin 2 rotates, and the guide plate 6 pushes powder accumulated in the center of the rotary bin 2 to dredge and break up the powder. The powder in the middle of the rotary bin 2 above the discharge port 12 is firstly discharged out of the hopper body 1 from the discharge port 12, and then the powder between the guide plates 6 slides out of the discharge port 12 along the side wall of the rotary bin 2.

After the discharging is finished, the output end of the hydraulic cylinder 84 extends out to push the baffle 81 to rotate along the axis of the connecting shaft 83 to block the discharging port 12, and the discharging is stopped.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
