Description

Technical Field

[0001] The utility model relates to the technical field of building material storage equipment, in particular to a machine-made sand feeding device. Background Art

[0002] Artificial sand refers to rock particles with a particle size of less than 4.75mm after mechanical crushing. It is mainly divided into granite sand, pebble sand, limestone sand, construction waste sand, etc. When the artificial sand is discharged from the storage bin, the sand and gravel in the discharge bin are agglomerated or the discharge port is blocked due to the excessive discharge speed.

[0003] For example, the patent publication number CN212530814U discloses a "material discharge structure of a machine-made sand batching bin", which includes a batching bin body, a discharge port is provided at the bottom of the batching bin body, and a plastic plate is attached to the inner wall of the batching bin body. This structure is conducive to material discharge. However, the machine-made sand will clump after a period of time, and can only be cleared by workers from the discharge port upward or from the discharge bin entrance downward with an iron rod, which is not only easy to cause blockage, but also easy to form agglomerates. If the material is directly discharged and mixed with mortar, the agglomerates will affect the subsequent mixing and the quality of the formed product. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a machine-made sand feeding device to solve the problems of easy blockage and the formation of agglomerates that affect subsequent mixing.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A machine-made sand feeding device comprises a feeding bin and a vibrating screen, wherein a supporting frame is fixedly installed on both sides of the feeding bin, a first spring is installed on the supporting frame, brackets are fixedly installed on both sides of the vibrating screen of the first spring, a mounting frame is fixedly installed on the bottom of the vibrating screen, a vibration motor is installed on the mounting frame, a vibration shaft is fixedly installed on the top of the vibrating screen, and a supporting claw is fixedly installed on the vibration shaft.

[0007] Preferably, the discharge port of the lower material bin is respectively installed with a first valve plate and a second valve plate, a first gear is fixedly installed on the side of the first valve plate, a second gear is installed on the side of the second valve plate, the first gear and the second gear are meshingly connected, the first gear and the second gear are both rotatably installed on the side of the lower material bin, and the first valve plate and the second valve plate are provided with openings at positions relative to the vibration axis.

[0008] Preferably, a cross bar is fixedly installed inside the lower silo, a sleeve is fixedly installed at the bottom of the cross bar, the vibration shaft moves in the sleeve, and a second spring is installed in the sleeve.

[0009] To sum up, the beneficial effects of the utility model are as follows: the machine-made sand feeding device provided by the utility model can drive the vibration shaft and the vibration screen to vibrate by utilizing the vibration motor. When the machine-made sand is in the feeding bin, the extrusion structure formed will be destroyed by the vibration of the vibration shaft and the support claws, thereby solving the problem that the machine-made sand is easily clogged by agglomeration; at the same time, the vibration of the vibration motor combined with the vibration screen can disperse the lumped machine-made sand materials, so that the machine-made sand materials after feeding are dispersed, solving the problem of affecting subsequent mixing.

[0016] like Figure 1 - Figure 3As shown, the utility model provides a machine-made sand feeding device, comprising a feeding bin 1 and a vibrating screen 2, a supporting frame 3 is fixedly installed on both sides of the feeding bin 1, a first spring 4 is installed on the supporting frame 3, brackets 5 are fixedly installed on both sides of the vibrating screen 2 of the first spring 4, a mounting frame 6 is fixedly installed on the bottom of the vibrating screen 2, a vibration motor 7 is installed on the mounting frame 6, a vibration shaft 8 is fixedly installed on the top of the vibrating screen 2, and a supporting claw 9 is fixedly installed on the vibration shaft 8.

[0017] The machine-made sand is stored in the discharge bin 1 for standby use. The vibration motor 7 can drive the vibration shaft 8 and the vibrating screen 2 to vibrate. When the machine-made sand is in the discharge bin 1, the extrusion structure formed will be destroyed by the vibration of the vibration shaft 8 and the supporting claws 9. The principle is similar to manually poking the material with an iron rod to destroy the extrusion structure, so that the machine-made sand accumulated for a long time can also be gradually discharged. The machine-made sand discharged from the discharge port falls on the vibrating screen 2. If the machine-made sand is stuck together, the vibration of the vibration motor 7 and the vibrating screen 2 can be used to vibrate the lumped machine-made sand materials, so that the machine-made sand materials after discharge are dispersed.

[0018] The discharge port of the lower silo 1 is respectively installed with a first valve plate 10 and a second valve plate 11, a first gear 12 is fixedly installed on the side of the first valve plate 10, and a second gear 13 is installed on the side of the second valve plate 11, the first gear 12 and the second gear 13 are meshingly connected, and the first gear 12 and the second gear 13 are both rotatably installed on the side of the lower silo 1, and the first valve plate 10 and the second valve plate 11 are provided with openings 14 relative to the position of the vibration shaft 8. The first valve plate 10 and the second valve plate 11 can act as valves, and the first gear 12 is driven to rotate by a manual lever or an electric means, so that the first valve plate 10 and the second valve plate 11 can be opened to the front and back of the lower silo 1 respectively, and the openings 14 are provided to leave space for the vibration shaft 8, and this opening method will not affect the use of the vibration screen 2.

[0019] A cross bar 15 is fixedly installed inside the lower bin 1, a sleeve 16 is fixedly installed at the bottom of the cross bar 15, the vibration shaft 8 moves in the sleeve 16, and a second spring 17 is installed in the sleeve 16. The cross bar 15 is provided to strengthen the support for the vibration shaft 8, and the second spring 17 is used for septum connection, so that the vibration shaft 8 can vibrate normally.

[0020] Working principle: When in use, the machine-made sand is stored in the discharge bin 1 for standby use. When discharge is required, the first valve plate 10 and the second valve plate 11 can be opened, and the vibration motor 7 can drive the vibration shaft 8 and the vibrating screen 2 to vibrate. When the machine-made sand is in the discharge bin 1, the extrusion structure formed will be destroyed by the vibration of the vibration shaft 8 and the supporting claw 9. The machine-made sand discharged from the discharge port falls on the vibrating screen 2. If the machine-made sand is stuck together, the vibration of the vibration motor 7 and the vibrating screen 2 can be used to vibrate the lumped machine-made sand materials, so that the machine-made sand materials after discharge are dispersed.
