Description

Technical Field

[0001] This utility model relates to the field of anti-blocking device technology, specifically to an anti-blocking device for loosening material in a discharge funnel. Background Technology

[0002] In bulk cargo unloading operations at docks, unloading hoppers allow materials to be directly loaded into trucks for transfer. The hoppers can also store a certain amount of material, enabling essentially continuous material transfer operations. The principle is that the gantry crane uses a grab bucket to pick up materials from the ship and drop them into the unloading hopper. Once the truck is in position, the hopper gate is opened, and the material in the hopper falls directly into the truck. The truck is full and drives away, while the next truck enters and takes its place. For materials with high flowability, unloading hoppers are highly efficient, quickly completing unloading and material transfer operations.

[0003] However, for some materials with high viscosity or very fine particle size, such as copper concentrate powder, when the moisture content is high, the viscosity is very high and it will adhere to the hopper wall. For large unloading hoppers, because they store a lot of material, such as the unloading hopper for a 40t gantry crane, the storage capacity can usually reach 70-80 tons. The material at the bottom of the unloading hopper is affected by the gravity of the material above, and the material at the bottom is under great force. Since the copper concentrate powder has a very fine particle size, the material at the bottom will be compacted into blocks, thus blocking the unloading port and preventing the material from falling into the truck. Manual unblocking is required, which greatly increases the labor intensity and reduces the work efficiency.

[0004] Therefore, there is an urgent need for a material loosening and anti-clogging device for unloading funnels to solve the problem of unblocking unloading funnels. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a material loosening and anti-clogging device for a discharge funnel, thereby solving the problem of unblocking the discharge funnel.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A material loosening and anti-clogging device for a discharge hopper includes a vibrating motor, a vibrating plate, and a hinge frame. The vibrating plate includes a base plate, several serrated plates, and a drive column. The upper end of the base plate is swayably mounted on the inner wall of the discharge hopper via the hinge frame, and the lower end of the base plate hangs naturally from the inner wall of the discharge hopper. Several serrated plates are spaced apart on the side of the base plate away from the inner wall of the discharge hopper. A drive column is provided at the lower end of the side of the base plate near the inner wall of the discharge hopper. A drive hole is provided on the side wall of the discharge hopper corresponding to the drive column. The drive column extends out of the discharge hopper from the drive hole and is connected to the vibrating motor. The vibrating motor is used to drive the base plate to swing around the hinge frame, and the drive hole allows the drive column to move with the base plate.

[0008] To optimize the above technical solution, the specific measures also include:

[0009] Furthermore, the hinge frame includes a fixed support plate and a pin. The upper end of the side of the base plate near the inner wall of the unloading funnel is provided with a connecting lug. The side wall of the unloading funnel is provided with a mounting hole corresponding to the connecting lug. A fixed support plate is fixedly provided on the side of the mounting hole located on the outside of the unloading funnel. A pin is installed between two opposite fixed support plates. The connecting lug extends out of the unloading funnel from the mounting hole and is hinged to the pin. The mounting hole allows the connecting lug to move with the base plate. There is a gap between the upper end of the base plate and the inner wall of the unloading funnel, allowing the base plate to swing around the pin.

[0010] Furthermore, a rubber pad layer is provided at the upper end of the bottom plate, between the bottom plate and the inner wall of the unloading hopper.

[0011] Furthermore, the base plate can be vertically oscillatingly mounted on the pin via a connecting lug.

[0012] Furthermore, several of the serrated plates are respectively and vertically arranged at equal intervals on the base plate.

[0013] Furthermore, two connecting ears are symmetrically provided, and two sets of hinge frames are provided accordingly.

[0014] Furthermore, a rubber gasket is provided on the inner wall of the unloading funnel and on the outer side of the drive hole.

[0015] Furthermore, several of the serrated plates can be parallel to each other, and the serrations on adjacent serrated plates are respectively staggered and arranged on the base plate.

[0016] Furthermore, it also includes a fall protection safety rope, one end of which is fixed to the outer wall of the unloading hopper, and the other end is fixedly connected to the vibrating motor. The length of the rope between the fall protection safety rope and the vibrating motor is sufficient for the vibrating motor to move with the base plate.

[0017] Furthermore, the surface of the serrated plate is smooth.

[0018] The beneficial effects of this utility model are:

[0019] This invention, through the arrangement of a vibrating motor, a vibrating plate, and a hinged frame, allows the centrifugal force of the vibrating motor to drive the drive column, carrying the base plate, to swing around the hinged frame. This achieves vibrational impact of the base plate on the material. Simultaneously, the several rake-like or toothed serrated plates on the base plate facilitate the cutting of compacted materials through line contact during the base plate's movement, loosening the material more easily and thus solving the problem of unblocking the discharge hopper and completing the unloading process. This invention avoids the situation where simple surface contact between the base plate and the material can cause the vibrating plate to further compact the material during impact.

[0020] In this invention, the vibratory motor is installed on the outside of the unloading hopper via a drive column, which provides effective movement space for the vibratory motor, avoids occupying the internal space of the unloading hopper, and facilitates the disassembly, assembly, and maintenance of the vibratory motor. At the same time, the drive hole allows the drive column to move with the base plate, and its size and shape can be adjusted as needed to avoid interfering with the movement of the drive column with the base plate.

[0021] The fixed support plate and pin shaft set on the outside of the unloading hopper of this utility model can facilitate the disassembly and assembly of the bottom plate and other structures, and increase the convenience of disassembly, assembly and maintenance of the device; at the same time, the mounting hole allows the connecting lug to move with the bottom plate, and its size and shape can be adjusted as needed to avoid interference with the movement of the connecting lug with the bottom plate. In addition, there is a gap between the upper end of the bottom plate and the inner wall of the unloading hopper, which allows the bottom plate to swing around the pin shaft, so as to avoid the inner wall of the unloading hopper interfering with the swing of the bottom plate.

[0022] This invention, through the setting of the rubber pad layer, can provide a gap for the bottom plate to swing around the pin shaft, and can also increase the airtightness between the bottom plate and the unloading hopper, reducing material leakage. At the same time, it can reduce rigid impact between structures and extend the service life of the device.

[0023] This invention uses a fall-prevention safety rope as a backup protection measure to prevent the vibrating motor from falling and being damaged due to loose bolts. Attached Figure Description

[0031] The present invention will now be described in detail with reference to the accompanying drawings.

[0032] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 As shown in the figure, a material loosening and anti-clogging device for a discharge funnel according to an embodiment of the present invention includes a vibrating motor 1, a vibrating plate 2, and a hinge frame. The vibrating plate 2 includes a base plate, several serrated plates 21, and a drive column 22. The upper end of the base plate is swayably mounted on the inner wall of the discharge funnel 6 through the hinge frame, and the lower end of the base plate hangs naturally from the inner wall of the discharge funnel 6. Several serrated plates 21 are installed at intervals on the side of the base plate away from the inner wall of the discharge funnel 6. The lower end of the side of the base plate near the inner wall of the discharge funnel 6 is provided with a drive column 22. A drive hole is opened on the side wall of the discharge funnel 6 corresponding to the drive column 22. The drive column 22 extends out of the discharge funnel 6 from the drive hole and is connected to the vibrating motor 1 by bolts. The vibrating motor 1 is used to drive the base plate to swing around the hinge frame, and the drive hole allows the drive column 22 to move with the base plate.

[0033] This invention, through the arrangement of a vibrating motor 1, a vibrating plate 2, and a hinged frame, allows the vibrating motor 1 to drive the drive column 22, carrying the base plate, to swing around the hinged frame via centrifugal force, thereby achieving vibrational impact of the base plate on the material. Simultaneously, the several rake-like or toothed sawtooth plates 21 on the base plate can easily cut compacted materials through line contact during the base plate's movement, thus loosening the material and solving the problem of unblocking the unloading hopper, completing the unloading process. This invention avoids the situation where simple surface contact between the base plate and the material can cause the vibrating plate 2 to further compact the material during impact.

[0034] The vibratory motor 1 is installed on the outside of the unloading hopper 6 via the drive column 22, which provides effective movement space for the vibratory motor 1, avoids occupying the internal space of the unloading hopper 6, and facilitates the disassembly, assembly and maintenance of the vibratory motor 1. At the same time, the drive hole allows the drive column 22 to move with the base plate, and its size and shape can be adjusted as needed to avoid interfering with the movement of the drive column 22 with the base plate.

[0035] When in use, this utility model device can be set up in the unloading funnel 6 with arrays of devices that are staggered vertically or have different positions and directions as needed.

[0036] As attached Figure 5 As shown, in another specific embodiment based on the above, the hinge frame includes a fixed support plate 3 and a pin 4. The upper end of the side of the bottom plate near the inner wall of the unloading funnel 6 is provided with a connecting ear. The side wall of the unloading funnel 6 is provided with a mounting hole corresponding to the connecting ear. The fixed support plate 3 is welded and fixed to the side of the mounting hole located on the outside of the unloading funnel 6. The pin 4 is installed between the two opposite fixed support plates 3. The connecting ear extends out of the mounting hole from the unloading funnel 6 and is hinged to the pin 4. The mounting hole allows the connecting ear to move with the bottom plate. There is a gap between the upper end of the bottom plate and the inner wall of the unloading funnel 6, which allows the bottom plate to swing around the pin 4. Thus, the fixed support plate 3 and pin 4 located on the outside of the unloading hopper 6 can facilitate the disassembly and assembly of the bottom plate and other structures, increasing the convenience of disassembly, assembly and maintenance of the device; at the same time, the mounting hole allows the connecting lug to move with the bottom plate, and its size and shape can be adjusted as needed to avoid interference with the movement of the connecting lug with the bottom plate, and there is a gap between the upper end of the bottom plate and the inner wall of the unloading hopper 6, which allows the bottom plate to swing around the pin 4, so as to avoid the inner wall of the unloading hopper 6 interfering with the swing of the bottom plate.

[0037] As attached Figure 6 As shown, a rubber pad 8 is provided at the upper end of the base plate, between the base plate and the inner wall of the discharge hopper 6. The rubber pad 8 provides clearance for the base plate to swing around the pin 4, increases the airtightness between the base plate and the discharge hopper 6, reduces material leakage, and also reduces rigid impact between structures, extending the service life of the device.

[0038] The aforementioned base plate is vertically swaying and mounted on the pin 4 via connecting lugs. Several of the aforementioned serrated plates 21 are vertically arranged at equal intervals on the base plate. This allows for better material loosening by coordinating with the vertical swaying of the base plate.

[0039] The aforementioned connecting lugs are symmetrically arranged in two sets, and the hinge frames are correspondingly arranged in two sets. This increases the stability of the structure.

[0040] In another specific embodiment based on the above, a rubber gasket is provided on the inner wall of the unloading funnel 6, located outside the drive hole. In this way, the rubber gasket can both seal the drive hole to a certain extent and reduce rigid impacts between structures during movement, thus extending the service life of the device.

[0041] In another specific embodiment based on the above, several serrated plates 21 can be parallel to each other, and the serrations on adjacent serrated plates 21 are respectively staggered and welded onto the base plate.

[0042] In another specific embodiment based on the above, a fall-prevention safety rope 5 is also included. One end of the fall-prevention safety rope 5 is fixed to the outer wall of the unloading hopper 6, and the other end is fixedly connected to the vibrating motor 1. The rope length between the fall-prevention safety rope 5 and the vibrating motor 1 is sufficient for the vibrating motor 1 to move with the base plate. In this way, the fall-prevention safety rope 5 can be used as a backup protection measure to prevent the vibrating motor 1 from falling and being damaged due to loose bolts.

[0043] In another specific embodiment based on the above, the surface of the serrated plate 21 is smooth. In this solution, the serrated plate 21 can be made of 316 stainless steel. 316 stainless steel has high wear resistance, which can increase the service life of the device and reduce maintenance costs. At the same time, the high smoothness of stainless steel reduces the contact resistance when the vibrating plate hits the material, thus reducing the vibration of the funnel.

[0044] One specific embodiment of this utility model is as follows:

[0045] Taking the loading and unloading of copper concentrate powder as an example, before the gantry crane loads the unloading hopper 6, the hopper gate 7 is closed. Then, the gantry crane grabs the material and loads it into the unloading hopper 6. The truck then enters the discharge port below the unloading hopper 6 and positions itself. The hopper gate 7 opens, and the material in the unloading hopper 6 falls into the truck bed through the discharge port. However, due to the extremely small size of the copper concentrate powder particles and its moisture content, the material at the outlet of the unloading hopper 6 is compressed into lumps by the gravity of the material above, blocking the discharge port and preventing it from falling freely. At this point, the vibration motor 1 is started. The vibration motor 1 drives the vibration plate 2 to swing around the pin shaft 4, causing the serrated plate 21 on the vibration plate 2 to continuously strike and cut the lumps, breaking up the lumps at the outlet of the unloading hopper 6 so that they can fall freely into the truck bed, thus completing the loading and unloading operation.

[0046] In this design, the serrated plate 21 on the vibrating plate 2 ensures that the contact between the vibrating plate 2 and the material is no longer a simple surface contact, but a line contact. This allows the vibrating plate 2 to continuously strike and cut the blocky material during its oscillation, enabling the material to fall smoothly from the outlet of the discharge hopper 6. This device solves the problem of material blockage in the discharge hopper 6, thereby improving the operating efficiency of the discharge hopper 6.

[0047] It should be noted that the terms such as "upper", "lower", "left", "right", "front", and "back" used in this utility model are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0048] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should be considered within its protection scope.
