In the figure: 1. the device comprises a small hopper, a blowing nozzle 2, a bracket 3, a striker plate 4, a door opening cylinder 5, a support 6, a slit 7, a vibrator 8, a feeding hole 9, a tongue plate 10 and an air inlet connecting pipe 11.

Detailed Description

As shown in fig. 1-4, the anti-hardening, anti-arching and anti-wall-sticking storage device of the automatic weighing and feeding system comprises a small hopper 1 for precise feeding, a vibrator 8 fixed on the outer side wall of the small hopper 1, and a striker plate 4 arranged at the discharge opening at the bottom of the small hopper 1. The lower part of the small hopper 1 is provided with a pyramid-shaped outer wall, two thin slits 7 are symmetrically arranged on one side of the pyramid-shaped outer wall, the lower ends of the thin slits 7 extend to a discharge opening of the small hopper, and a tongue-shaped plate 10 with the upper end connected with a main body of the small hopper is formed between the two thin slits 7. The air inlet pipe 11 is fixed outside the air inlet hole, the blowing nozzle 2 is fixed at the tail end of the air inlet pipe 11, specifically, the blowing nozzle 2 is in threaded connection with the air inlet pipe 11, the air inlet pipe 11 is welded and fixed with the small hopper 1, and the blowing nozzle 2 is externally connected with an air pipe and used for being connected with an air source.

In this embodiment, referring to fig. 3, the tongue plate 10 is narrow at the top and wide at the bottom, and the width of the bottom is smaller than the width of the middle but larger than the width of the top. This design is advantageous for achieving different amplitudes of the tongue plate 10 and the small hopper 1. The lower part of support 6 is the fixed cylinder 5 that opens the door of little hopper side dorsad, striker plate 4 is located 3 upper surfaces of bracket and is connected fixedly with the jar pole of cylinder 5 that opens the door, be equipped with the mouth of dodging that corresponds little hopper discharge opening on the bracket 3, bracket 3 is responsible for 4 direction and supports for the striker plate. The blowing nozzle 2 is arranged in a perpendicular relationship with the tongue plate 10. The rear side surface of the upper part of the small hopper 1 is provided with a feeding hole 9 for receiving materials transmitted by a conveyor belt of an automatic weighing and feeding system. When in use, the small hopper 1 is fixed on the frame of the equipment.

During operation, the cylinder 5 that opens the door drives the motion of striker plate 4, make the discharge opening of little hopper 1 opened, 8 work production vibrations of vibrator simultaneously, the tongue board 10 of little hopper lower part is different with the amplitude of little hopper main part during vibration, tongue board 10 amplitude is greater than little hopper main part, and then tongue board 10 breaks up the material of little hopper 1 inside, blow 2 simultaneously and blow the fluffy of blowing to the material of little hopper 1 inside, the adhesion of material on 1 inner wall of little hopper has also been avoided simultaneously, also make the material from the easier dropping of little hopper, the cylinder 5 that opens the door when the material adds the target value drives 4 reverse motion of striker plate, make the discharge opening of little hopper 1 blocked, and then stop the blanking. In the working process, a small amount of materials overflow from the slit of the small hopper 1 due to vibration, but finally all the materials fall on the weighing device, and the metering and feeding are not influenced.

The embodiments of the present invention have been described in detail, but the description is only for the preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made within the scope of the present invention should be covered by the present patent.
