Description

Technical Field

[0001] This utility model belongs to the field of storage warehouse technology, specifically relating to a sand and gravel aggregate storage warehouse. Background Technology

[0002] Stone aggregate is a general term for materials such as sand, pebbles (gravel), crushed stone, boulders, and aggregates used in water conservancy projects. During concrete processing, aggregate bins are needed to store sand and gravel. These sand and gravel aggregate storage bins are devices used for storing and transporting sand and gravel aggregates, widely used in construction sites, road and bridge construction, and other fields. They effectively improve work efficiency, reduce manpower input, and ensure the quality and safety of aggregates.

[0003] Existing aggregate storage silos have fixed discharge port sizes. When aggregates flow towards the discharge port under gravity within the silo, uneven particle shape and size, along with friction and cohesion, easily lead to aggregate buildup above the discharge port, forming bridging. This bridging severely hinders normal aggregate flow, causing sluggish aggregate descent, reducing discharge efficiency, potentially causing equipment malfunctions, and increasing the risk of production interruptions. Therefore, a new type of aggregate storage silo is needed to address this problem. Utility Model Content

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes an agitator installed inside the collection funnel. When the agitator motor is activated, it drives the agitator shaft to rotate. As the agitator shaft rotates, it agitates the sand and gravel aggregate, thereby ensuring that the sand and gravel aggregate can fall and be discharged stably. This effectively avoids the accumulation phenomenon that easily occurs in the area above the discharge port due to the uneven shape and size of the aggregate particles, as well as the friction and cohesion between materials, which can lead to bridging and other issues.

[0017] This invention utilizes a combination of air guide components and air distribution components located on the outer side of the storage chamber. A rotating motor drives the air guide wheel to rotate, drawing external airflow into the hot air chamber. Simultaneously, a pneumatic heating rod heats the airflow passing through it, causing the hot air to enter the connecting pipe through the guide pipe and be ejected into the storage chamber through the nozzles on the connecting pipe. This process assists in drying the sand and gravel aggregate inside the storage chamber, effectively removing moisture from the sand and gravel and minimizing excess moisture residue that could lead to water-cement ratio imbalances during subsequent use.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This specific embodiment is a sand and gravel aggregate storage bin, such as... Figure 1 , Figure 2 and Figure 3 As shown, the sand and gravel aggregate storage bin includes a storage bin body 1 and a base frame 4 fixed to the bottom of the storage bin body 1. A top plate 2 is installed at the top of the storage bin body 1. Support rods 3 are fixed between the storage bin body 1 and the top plate 2. Four support rods 3 are symmetrically arranged. The top plate 2 can effectively block rainwater and other water. A storage cavity is opened inside the storage bin body 1. A funnel-shaped collection funnel 5 is set at the bottom of the storage bin body 1. A discharge seat 6 is protruding at the bottom of the collection funnel 5. A discharge port is vertically opened through the discharge seat 6. A baffle plate 7 is inserted and installed at the discharge seat 6.

[0026] The collection funnel 5 has a discharge port at its bottom, and an agitation component 8 is installed at the discharge port. The agitation component 8 includes a cross-shaped mounting frame 9 fixed inside the collection funnel 5. A mounting box 10 is fixed at the center of the top of the mounting frame 9. An agitation motor 11 is installed inside the mounting box 10 at the top of the mounting frame 9. An agitation shaft 12 is fixed at the front end of the shaft of the agitation motor 11. The agitation shaft 12 is spiral in shape.

[0027] By starting the stirring component 8 installed inside the collection funnel 5, the stirring motor 11 is activated. The stirring motor 11 drives the stirring shaft 12 to rotate as a whole. When the stirring shaft 12 rotates, it drives the sand and gravel aggregate to stir, thereby ensuring that the sand and gravel aggregate can fall and be discharged stably. This can effectively avoid the phenomenon of accumulation in the area above the discharge port due to the uneven shape and size of the aggregate particles and the friction and cohesion between materials, which can lead to bridging and other situations.

[0028] Reference Figure 1 , Figure 2 and Figure 4As shown, an air guide assembly 13 is installed on the side of the storage chamber body 1. A hot air chamber is symmetrically formed near the outer edge of the storage cavity of the storage chamber body 1. An air distribution assembly 17 is installed inside the hot air chamber. The air guide assembly 13 and the air distribution assembly 17 are connected and cooperate with each other. A baffle net 20 is fixed at the outer edge of the hot air chamber. Several connecting pipes 18 are installed at equal intervals inside the hot air chamber. Adjacent connecting pipes 18 are connected through a conduit 19. The conduit 19 is connected to the air guide assembly 13. The air guide assembly 13 includes an installation... An air guide box 14 is located on the side of the storage compartment body 1. An air guide wheel 15 is rotatably installed inside the air guide box 14. A rotating motor that drives the air guide wheel 15 to rotate is installed on one side of the air guide box 14. An air inlet is opened on one side of the air guide box 14 corresponding to the side of the air guide wheel 15. A guide pipe 141 is protruding on the other side of the air guide box 14. The guide pipe 141 is connected to the connecting pipe 18. A heating chamber is opened inside the air guide box 14. Several heating rods 16 are installed in the heating chamber.

[0029] Through the cooperation of the air guide assembly 13 and the air distribution assembly 17 set on the outer side of the storage chamber body 1, the rotating motor drives the air guide wheel 15 to rotate as a whole. When the air guide wheel 15 rotates, it drives the external airflow into the hot air cavity. At the same time, the pneumatic rod heating rod 16 heats the airflow passing through it, so that the hot air enters the connecting pipe 18 through the guide pipe 141 and is sprayed into the storage chamber body 1 through the nozzle on the connecting pipe 18. This provides auxiliary hot air drying treatment for the sand and gravel aggregate inside the storage chamber body 1, effectively removing moisture between the sand and gravel inside the storage chamber body 1, and minimizing excess moisture residue in the storage cavity inside the storage chamber body 1, which could cause water-cement ratio imbalance during subsequent use.

[0030] A support frame 21 is installed inside the aforementioned storage cavity. The support frame 21 has a cross-shaped frame structure. The support frame 21 can effectively support the entire storage chamber body 1 during operation.

[0031] Working principle:

[0032] During operation, the sand and gravel aggregate is poured into the storage cavity inside the storage bin body 1. The rotating motor is started, which drives the guide wheel 15 to rotate. When the guide wheel 15 rotates, it draws external airflow into the hot air cavity. At the same time, the pneumatic heating rod 16 heats the airflow passing through it, so that the hot air enters the connecting pipe 18 through the guide pipe 141 and is sprayed into the storage bin body 1 through the nozzle on the connecting pipe 18, thereby providing auxiliary hot air drying treatment for the sand and gravel aggregate inside the storage bin body 1.

[0033] Remove the baffle plate 7. After the baffle plate 7 is removed, the sand and gravel aggregate falls and is discharged through the discharge port and the outlet. During the discharge, start the stirring motor 11. The stirring motor 11 drives the stirring shaft 12 to rotate as a whole. When the stirring shaft 12 rotates, it drives the sand and gravel aggregate to stir, thereby ensuring that the sand and gravel aggregate can fall and be discharged stably.

[0034] All technical features in this embodiment can be freely combined according to actual needs.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
