The specific embodiment
Describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is traditional Dump gate structural representation.As shown in Figure 1, feed bin 1 middle part that has discharge port 2 is provided with discharging door-hinge P, and Dump gate arc body 3 is connected with cylinder 5 one ends by auricle 4, and cylinder 5 other ends are fixed on the feed bin 1.It serves as the axle rotation with discharging door-hinge P (also claiming Dump gate pivot P) that cylinder 5 drives Dump gate arc body 3, thereby realizes the opening and closing of discharge port 2.
The design of tradition Dump gate, its Dump gate arc body 3 and discharge port arc plate 2 ' shape all to adopt with discharging door-hinge P be the camber line in the center of circle, promptly Dump gate pivot P and Dump gate arc body center of circle Q and discharge port arc plate 2 ' center of circle K overlap (as Fig. 1).Because Dump gate pivot P overlaps with the center of circle K of Dump gate arc body center of circle Q and discharge port arc plate, when Dump gate arc body 3 is opened, Dump gate arc body 3 is around the discharging door-hinge P rotation that overlaps, Dump gate arc body 3 need overcome the frictional force between material and the Dump gate arc body 3, in case have stone be embedded in Dump gate arc body 3 and discharge port arc plate 2 ' between, will strengthen frictional resistance, when driving force can't overcome friction, Dump gate arc body 3 will occur not opening or close incessantly phenomenon, can't discharging or metering off-gage phenomenon thereby cause.
For solving the Dump gate phenomenon of not opening, the first step of technical solutions of the utility model adopts the eccentric setting in the Dump gate pivot and the Dump gate arc body center of circle.Fig. 2 is the structural representation with the eccentric structure Dump gate of opening the door.As shown in Figure 2, Dump gate arc body center of circle Q is arranged on Dump gate pivot P left side, and offset distance is A, and promptly Dump gate arc body 3 is to be the center of circle, to be the camber line MN of radius with QM (or QN) with Dump gate arc body center of circle Q.Simultaneously, discharge port arc plate 2 ' shape meet Dump gate arc body, promptly be the center of circle, be the camber line of radius with QM (or QN) with Dump gate arc body center of circle Q.
When Dump gate arc body 3 was opened, Dump gate arc body 3 was around Dump gate pivot P rotation.Because of Dump gate arc body center of circle Q is arranged on Dump gate pivot P left side, so the radius of gyration PM of Dump gate arc body 3 is bigger than PN.The result that radius of gyration PM is bigger than PN makes Dump gate arc body 3 when opening, and is equivalent to both rotate, and a trend that moves downward is arranged again, on the Dump gate arc body 3 any point with respect to discharge port arc plate 2 ' between distance increasing.At this moment, even have the stone plug Dump gate arc body 3 and discharge port arc plate 2 ' between, because of discharge port and the increase of Dump gate relative gap, stone is in free state and can't produces extruding force, thereby the rotary resistance that 3 need of Dump gate arc body overcome Dump gate pivot P place gets final product, so Dump gate arc body 3 is easy to open.After Dump gate arc body 3 was opened fully, Dump gate arc body 3 left hand edges and discharge port arc plate 2 ' right edge were on same vertical line, and the two has vertical range B.
Obviously, though technique scheme has scientifically solved the Dump gate phenomenon of not opening, but still there is the Dump gate problem of not closing.By the eccentric technical scheme that is provided with of the above-mentioned Dump gate pivot and the Dump gate arc body center of circle, when Dump gate is closed, because of discharge port arc plate 2 ' and Dump gate arc body 3 between the gap more and more littler, in case stone squeeze Dump gate arc body 3 and discharge port arc plate 2 ' between, stone can be crowded more tight more, up to Dump gate is blocked, can't close the door.
For solving the Dump gate problem of not closing in the technique scheme, on the technique scheme basis, be under the eccentric prerequisite that is provided with in the Dump gate pivot and the Dump gate arc body center of circle, second step of technical solutions of the utility model is adopted the eccentric bidirectional eccentric technical scheme that is provided with of the Dump gate pivot and the discharge port arc plate center of circle.Fig. 3 is the structural representation with bidirectional eccentric Dump gate.As shown in Figure 3, the utility model bidirectional eccentric technical scheme is meant, discharge port arc plate center of circle K is arranged on Dump gate pivot P right side, offset distance is C, and be that radius forms new discharge port arc plate 2 with KN ", the promptly new discharge port arc plate 2 that forms " is to be the center of circle, to be the camber line M ' N of radius with KN with discharge port arc plate center of circle K.And Dump gate arc body 3 is still with Dump gate arc body center of circle Q and is the center of circle, is the camber line MN of radius with QM (or QN).
According to technique scheme, when Dump gate arc body 3 was closed, Dump gate arc body 3 was still around Dump gate pivot P rotation.Because of discharge port arc plate center of circle K is arranged on Dump gate pivot P right side, so PN is bigger than PM '.The result that PN is bigger than PM ' make Dump gate arc body 3 when closing on it each point " (camber line M ' distance N) is increasing, therefore the phenomenon that gets stuck can not occur, and Dump gate arc body 3 can be closed very easily with respect to discharge port arc plate 2.After Dump gate arc body 3 was closed fully, " left hand edge was on the same vertical line, and the two has vertical range D for Dump gate arc body 3 left hand edges and discharge port arc plate 2.Obviously, distance D is greater than distance B.
The two eccentric technical schemes that are provided with of the utility model are practicable through facts have proved.
Distance A between above-mentioned arc Dump gate arc body center of circle Q and the Dump gate pivot P is 0.02～0.25 of Dump gate arc body 3 respective radius, and the distance C between above-mentioned discharge port arc plate center of circle K and the Dump gate pivot P is discharge port arc plate 2 " 0.02～0.25 of respective radius.Obviously, the setting of above-mentioned distance A and distance C also will be considered the characteristic size of material.
By technique scheme, owing to have design gaps between Dump gate and the discharge port, for guaranteeing the precision metering of material, the edge of discharge port adopts elastomeric material (as rubber) to be sealed.
The above-mentioned Dump gate arc body center of circle Q that mentions is meant the pairing center of circle of (interior) surperficial camber line on the Dump gate arc body 3, promptly near discharge port arc plate 2 " the pairing center of circle of a side surface camber line; Discharge port arc plate center of circle K is meant discharge port arc plate 2, and " the following pairing center of circle of (outward) surperficial camber line is promptly near the pairing center of circle of Dump gate arc body 3 one side surface camber lines.
It below only is the specific embodiment of the present utility model; but in any form the utility model is not made restriction; should be understood that; for a person skilled in the art; according to design philosophy of the present utility model and essence; can also make a lot of distortion and improvement, but these all will fall into protection domain of the present utility model.
