Description

Technical Field

[0001] The utility model relates to the technical field of dry-mix mortar production, in particular to an anti-clogging raw material storage bin. Background Art

[0002] Storage silos are essential infrastructure in dry-mix mortar production workshops. However, the discharge ports of these silos often experience blockage. This is because dry-mix mortar raw materials are often a mixture of various particles, forming a dense accumulation near the discharge port, which hinders the normal flow of the material. Furthermore, in actual production environments, the raw materials absorb a certain amount of moisture, causing them to clump and stick to the silo walls and discharge port, affecting the normal operation of the silo.

[0003] Therefore, in order to solve the defect that the material discharge port of the storage bin is easily blocked during use, it is necessary to propose an anti-blocking raw material storage bin. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-clogging raw material storage bin, which generates vibration through a vibration motor so that the discharge hopper can slide back and forth on the guide rod, destroying the densely accumulated dry powder structure at the discharge port, promoting the smooth fall of the material, and also helping to break up the lumps and prevent them from clogging the discharge port, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A blockage-resistant raw material storage bin comprises a storage bin, the storage bin being supported by a bracket and having a lower hopper mounted at its bottom, a guide rod being provided between the lower hopper and the storage bin, the guide rod being fixedly connected to the storage bin via a first clamping plate, the guide rod being slidably connected to the lower hopper via a second clamping plate, a spring being sleeved on the guide rod, the top end of the spring being welded to a lower surface of the clamping plate, and the bottom end of the spring being welded to an upper surface of the second clamping plate;

[0007] A first clamping ring is welded on the bottom of the storage bin, a second clamping ring is welded on the top of the lower hopper, and a rubber sleeve is bonded between the first clamping ring and the second clamping ring.

[0008] Preferably, vibration motors are fixedly installed on the left and right ends of the lower hopper.

[0009] Preferably, a servo motor is fixedly mounted on the top of the bracket, and an output end of the servo motor is fixedly connected to a drive shaft, and the drive shaft runs through the entire storage bin and the lower hopper.

[0010] Preferably, stirring rods are symmetrically installed on one end of the driving shaft located in the lower hopper, and multiple groups of stirring rods are arranged up and down, and the length becomes shorter as the rods go down.

[0011] Preferably, stirring rods are symmetrically installed on one end of the driving shaft located in the storage bin, and multiple groups of stirring rods are arranged above and below, and the distances between adjacent stirring rods are kept equal.

[0012] Preferably, one end of the stirring rod close to the inner wall of the storage bin is connected to a scraper plate.

[0013] Preferably, a material guide plate is welded to the bottom of the storage bin, and the material guide plate is in a truncated cone shape, and the diameter of its discharge port is smaller than the diameter of the feed port of the lower hopper.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. This anti-clogging raw material storage bin provides a unique movable and buffering mechanism for the hopper through the structure consisting of a guide rod, a first and second pallet, a spring, and a rubber sleeve. When the vibration motor is working, the hopper will slide up and down along the guide rod, which can effectively destroy the dense accumulation structure formed by the mixing of dry mortar particles near the discharge port, thereby promoting the smooth fall of materials. For materials that have agglomerated due to moisture absorption, vibration can also play a role in breaking up, preventing agglomerates from clogging the discharge port, ensuring continuous and stable material discharge.

[0016] 2. This anti-clogging raw material storage silo can prevent the material from forming local accumulation near the discharge port through the stirring rod, disrupt the aggregation state of the particles, and improve the fluidity of the material. The stirring rod can fully stir the material in the storage silo to prevent the material from being compacted or agglomerated due to long-term static state. The scraper can promptly scrape off the material stuck to the silo wall due to moisture absorption. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] To solve the technical problem of how to avoid clogging of the feed port, please refer to Figure 1-Figure 2 , this embodiment provides the following technical solutions:

[0023] A blockage-proof raw material storage bin includes a storage bin 1, which is supported by a bracket 3 and has a lower hopper 2 installed at its bottom. A guide rod 4 is provided between the lower hopper 2 and the storage bin 1. The guide rod 4 is fixedly connected to the storage bin 1 through a clamping plate 11, and the guide rod 4 is slidingly connected to the lower hopper 2 through a clamping plate 21. A spring 5 is sleeved on the guide rod 4, and the top end of the spring 5 is welded to the lower surface of the clamping plate 11, and the bottom end of the spring 5 is welded to the upper surface of the clamping plate 21. Vibration motors 23 are fixedly installed on the left and right ends of the lower hopper 2.

[0024] Specifically, when the vibration motors 23 at the left and right ends of the lower hopper 2 are started, the vibration force generated by the vibration motors 23 acts on the lower hopper 2. Since the lower hopper 2 is slidably connected to the guide rod 4 through the second clamping plate 21, the lower hopper 2 can slide up and down along the guide rod 4 under the action of the vibration force.

[0025] In this process, the spring 5 sleeved on the guide rod 4 plays an important role. When the lower hopper 2 slides upward, the spring 5 is compressed. The spring 5 is elastically deformed and stores energy under the force. When the vibration force of the vibration motor 23 causes the lower hopper 2 to slide downward, the spring 5 releases the previously stored energy and pushes the lower hopper 2 downward, while also playing a buffering role in the downward sliding of the lower hopper 2.

[0026] This structural design, in which the vibration motor 23 provides power, the guide rod 4 limits the movement direction, and the spring 5 provides buffering and auxiliary reset functions, enables the lower hopper 2 to produce stable and regular up and down vibrations. This vibration helps to destroy the dense stacking structure of the material in the lower hopper 2, prevents the material from being blocked at the discharge port of the lower hopper 2, and thus ensures that the material can be discharged smoothly.

[0027] To solve the technical problem of how to prevent the raw material particles from agglomerating in the silo, please refer to Figure 4 , this embodiment provides the following technical solutions:

[0028] A servo motor 31 is fixedly installed on the top of the bracket 3, and the output end of the servo motor 31 is fixedly connected to the drive shaft 32. The drive shaft 32 runs through the entire storage bin 1 and the lower hopper 2. The end of the drive shaft 32 located in the lower hopper 2 is symmetrically installed with stirring rods 33. There are multiple groups of stirring rods 33 up and down, and the length becomes shorter as it goes down. The end of the drive shaft 32 located in the storage bin 1 is symmetrically installed with stirring rods 34. There are multiple groups of stirring rods 34 up and down, and the distance between adjacent stirring rods 34 remains equal. The end of the stirring rod 34 close to the inner wall of the storage bin 1 is connected to a scraper plate 35.

[0029] Specifically, the servo motor 31 drives the drive shaft 32 to rotate, thereby rotating the stirring rods 33 located in the lower hopper 2. The stirring rods 33 are provided in multiple groups above and below. The stirring rods 33 of this multi-layer structure can stir the raw materials at different heights in the lower hopper 2. In the production process of dry mortar, the raw material particles are easily agglomerated due to mutual squeezing and static accumulation during the discharge process. The rotation of the stirring rods 33 can disrupt the accumulation state of the raw material particles, so that the particles are constantly rearranged and combined, thereby avoiding the particles from being in close contact for a long time to form agglomerates.

[0030] In the storage bin 1, the driving shaft 32 drives the stirring rods 34 installed symmetrically on the left and right to rotate. There are multiple groups of stirring rods 34 up and down and the distance between adjacent stirring rods 34 is kept equal, which enables the stirring rods 34 to fully and evenly stir the raw materials at different heights in the storage bin 1. For the raw materials in the storage bin 1, long-term static storage may cause the particles to agglomerate due to moisture, mutual squeezing and other factors. The stirring action of the stirring rods 34 can make the raw material particles constantly turn over to prevent the formation of a stable agglomeration structure between the particles.

[0031] It should be noted that the design of the stirring rod 33 becoming shorter as it goes down can adapt to the shape of the lower hopper 2 more accurately; near the silo wall of the storage silo 1, the raw materials are easily sticky due to absorbing moisture or friction with the silo wall. As time goes by, these sticky raw materials will gradually clump together, and the scraper plate 35 scrapes off the raw materials on the silo wall as the stirring rod 34 rotates.

[0032] See also Figure 3 A clamping ring 12 is welded at the bottom of the storage bin 1, a clamping ring 22 is welded at the top of the lower hopper 2, and a rubber sleeve 6 is bonded between the clamping ring 12 and the clamping ring 22.

[0033] It should be noted that the rubber sleeve 6 plays a sealing role and can effectively fill the gap between the clamp ring 12 and the clamp ring 2 22 to prevent the material from leaking from the connection part during the flow from the storage bin 1 to the lower hopper 2. It also has a buffering effect. The storage bin 1 and the lower hopper 2 will produce relative displacement and impact under the action of vibration. The rubber sleeve 6 can provide space for displacement and absorb impact energy.

[0034] See also Figure 3 A guide plate 13 is welded to the bottom of the storage bin 1. The guide plate 13 is truncated cone-shaped, and the diameter of its discharge port is smaller than the diameter of the feed port of the lower hopper 2.

[0035] It should be noted that the guide plate 13 can guide the materials in the storage bin 1, and can gradually guide the scattered materials to the direction of its discharge port, making the flow of materials more orderly. It is like a funnel, concentrating the materials to prevent the materials from being scattered around at the bottom of the storage bin 1 and forming dead corner accumulation.

[0036] Working principle: When the anti-clogging raw material storage bin is in use, the vibration motor 23 is started, and the vibration force generated by the vibration motor 23 will act on the lower hopper 2. Since the lower hopper 2 is slidably connected to the guide rod 4 through the clamping plate 21, under the action of the vibration force, the lower hopper 2 can slide up and down along the guide rod 4. In this process, the spring 5 sleeved on the guide rod 4 plays an important role. When the lower hopper 2 slides upward, the spring 5 is compressed. The spring 5 is subjected to elastic deformation and stores energy. When the vibration force of the vibration motor 23 causes the lower hopper 2 to slide downward, the spring 5 releases the previously stored energy and pushes the lower hopper 2 to move downward. At the same time, it also plays a buffering role in the downward sliding of the lower hopper 2. This structural design in which the vibration motor 23 provides power, the guide rod 4 limits the direction of movement, and the spring 5 provides buffering and auxiliary reset functions enables the lower hopper 2 to generate stable and regular up and down vibrations. This vibration helps to destroy the dense stacking structure of the material in the lower hopper 2 and prevents the material from being blocked at the discharge port of the lower hopper 2, thereby ensuring that the material can be discharged smoothly.
