[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0022] like Figure 1 As shown, a device for uniformly discharging materials at the feed port of a steady flow bin comprises: a bin body 1, the bottom of the bin body 1 is arranged as a vertical section, and an expanding section is arranged above the vertical section.
[0023] like Figure 2 As shown, the bottom end of the vertical section is provided with a discharge port, and a chute 2 is provided on the inner wall. Both ends of the chute 2 extend outwardly through the warehouse body 1.
[0024] A sliding plate 3 is provided in the sliding groove 2 for sliding fit. Figure 2 and Figure 5 As shown, the sliding plate 3 has an outlet 4 in the middle, with connecting plates 5 at either end. The outlet 4 is the same width as the discharge port, but shorter. The sides of the sliding plate 3 fit within the inwardly recessed chute 2, sealing the discharge port and allowing materials to fall only through the outlet 4.
[0025] Both ends of the sliding plate 3 extend to the outside of the warehouse body 1. The two connecting plates 5 are located outside the warehouse body 1 and can serve as a limiting mechanism as well as a connecting mechanism.
[0026] like Figure 1 and Figure 3 As shown, a first housing 6 is connected to the first side of the silo 1. The first housing 6 covers the first end of the sliding plate 3 and the exterior of the first connecting plate 5. A screw 7 is rotatably mounted within the housing. The screw 7 is threadedly connected to the first connecting plate 5, and one end is in driving connection with a drive motor 8 located outside the first housing 6. The drive motor 8 drives the screw 7 to rotate, which in turn drives the connected connecting plate 5 and sliding plate 3 to slide, thereby enabling the outlet 4 to slide back and forth within the discharge port.
[0027] Meanwhile, a second housing 13 is provided on the second side of the housing 1. This second housing 13 covers the second end of the sliding plate 3 and the exterior of the second connecting plate 5 to provide isolation and protection. A sliding rod 14 is provided within the second housing 13. The sliding rod 14 slidably engages with the connecting plate 5 to improve the sliding stability of the sliding plate 3.
[0028] like Figure 2 and Figure 4As shown, a number of evenly arranged shafts 9 are provided in the vertical section. A number of blades 10 are provided on the shaft 9, and one end of the shaft 9 extends to the outside of the warehouse body 1, and a gear 11 is provided at the end. A rack 12 is provided on one side of the gear 11 to engage with it. The rack 12 is arranged horizontally and fixedly connected to the connecting plate 5. Specifically, the rack 12 is located outside the first box body 6 and the second box body 13, and is connected to the connecting plate 5 through a slot provided on the first box body 6 and the second box body 13. When the sliding plate 3 slides under the drive of the driving motor 8, it can drive the rack 12 to move back and forth. The rack 12 can drive each gear 11 to rotate, and then drive the shaft 9 and the blade 10 to rotate, thereby achieving the effect of moving the material.
[0029] Preferably, the outer cover of the rack 12 is provided with a third box 16 to play an isolation and protection role.
[0030] A tilting platform 15 is provided inside the vertical section of the silo 1. The tilting platform 15 is located on the first side inner wall of the silo 1 and the second side inner wall of the silo 1, and is provided above the chute 2, with the bottom surface close to the sliding plate 3. The tilting platform 15 causes the vertical section of the silo 1 to tilt inward and contract, so that the material is concentrated toward the center. The preferred specific embodiments of the present utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the present utility model without creative labor. Therefore, all technical solutions that can be obtained by technicians in this technical field through logical analysis, reasoning or limited experiments based on the concept of the present utility model on the basis of existing technology should be within the scope of protection determined by the claims.
