Description

Technical Field

[0001] This utility model belongs to the field of hopper technology, specifically relating to a dust suppression unloading hopper. Background Technology

[0002] The hopper is an auxiliary device in the conveying system that connects the crane and the belt conveyor. When grain is unloaded from the grain silo, a large amount of dust is usually generated. Excessive dust can cause certain hazards and is detrimental to the physical and mental health of the workers. At the same time, some dust collection devices may accidentally suck up grain when collecting dust.

[0003] For example, Chinese utility model patent CN223032486U discloses a dust suppression hopper for soybean meal delivery in a bulk soybean meal storage facility, including a mounting plate with connection holes at each of the four corners. In this utility model, a connecting shell is fixed to the bottom of a spiral tube. By starting a speed-regulating motor, the spiral tube and the connecting shell move up and down. The moving connecting shell helps to limit the bottom of the hopper, thus facilitating control of the soybean meal discharge speed. The movement of the connecting shell also moves the circular shell, causing multiple moving rods and elastic pads to move. The downward movement of these rods and pads allows for adjustment of the size of the discharge port at the bottom of the hopper, thus facilitating adjustment of the soybean meal discharge volume and speed. Furthermore, the multiple moving rods and elastic pads concentrate the soybean meal, preventing it from dispersing during its descent and reducing the likelihood of dust carried within it escaping.

[0004] The existing dust suppression hopper is driven by a motor, which allows the size of the discharge hopper to be adjusted, thereby controlling the material discharge speed and achieving the purpose of dust suppression during material unloading. However, since the drive component is located inside the discharge hopper and the material particles are small, when a large amount of material enters the discharge hopper and continues to operate for a long time, it will affect the normal operation of the drive component.

The bottom of the adjusting assembly is connected to the top of the adjusting cone, and the top is fixedly connected to the pipe for controlling the discharge rate of the discharge hopper.

[0008] As a further technical solution, the anti-blocking component is a connecting plate, which is integrally formed from two plates welded at the top and arranged at an angle.

[0009] As a further technical solution, the adjusting assembly also includes a vertical rod and a rotating shaft. The rotating shaft is located behind the vertical rod, and both ends of the rotating shaft extend to the outside of the discharge hopper.

[0010] As a further technical solution, the output structure includes a rotating shaft, a worm gear is installed at the bottom of the rotating shaft, and a worm wheel is sleeved at one end of the rotating shaft, wherein the worm wheel and the worm gear mesh.

[0011] As a further technical solution, a bearing seat is installed at the connection between the rotating shaft and the discharge hopper, and two bearings are sleeved on the rotating shaft, with the bearings installed inside the bearing seat.

[0012] As a further technical solution, a mounting block is installed at the top of the adjusting cone, and the mounting block is bolted to the rack.

[0013] As a further technical solution, a triangular reinforcing rib is installed at one end of the vertical rod, and the bottom end of the triangular reinforcing rib is connected to the connecting plate. A rear cover is installed at the other end of the vertical rod, and the rear cover is connected to the vertical rod. The gear is set in the rear cover, and the top of the rear cover is triangular, with its bottom end connected to the connecting plate.

[0014] As a further technical solution, a protective cover is installed at the bottom of the output structure.

[0017] The beneficial effects of this utility model are:

[0018] An adjusting cone is installed inside the discharge hopper, allowing material to fall through the gap between the adjusting cone and the inner wall of the discharge hopper. This cone can trap dust from the mixed material and drop it in a columnar shape, improving the dust suppression effect during material fall. An adjusting component is installed on the adjusting cone, allowing it to rise or fall within the discharge hopper, thereby changing the gap between the adjusting cone and the inner wall of the discharge hopper. When the flow rate of material in the pipeline is low, the adjusting cone moves downward, causing the material in the discharge hopper to accumulate in the area above the adjusting cone, so that it can trap dust and drop in a columnar shape when falling through the gap. In addition, the adjusting component includes an anti-clogging component to prevent material from accumulating in the discharge hopper for a long time and causing blockage. A worm gear transmission structure is used as the drive for the adjusting component, accurately controlling the up and down movement of the adjusting cone. A rear cover is installed at the gear meshing point, allowing material to fall through the upper surface of the rear cover without causing blockage, thus not affecting the gear and rack meshing transmission and ensuring reliable transmission.

[0030] like Figure 1 As shown, this utility model provides a dust suppression unloading hopper, including a discharge hopper 1, a pipe 2 connected to the discharge hopper 1, and a cavity 102 formed inside the discharge hopper 1. Material falls into the cavity 102 of the discharge hopper 1 through the pipe 2. An adjusting cone 302 is installed inside the cavity 102, wherein the adjusting cone 302 is located inside the cavity 102, and there is a gap between the outer ring of the adjusting cone 302 and the cavity 102, so that the material falls through the gap. The adjusting cone 302 is provided with a maximum diameter section 305. The diameter above the maximum diameter section 305 increases from top to bottom, while the diameter below the maximum diameter section 305 decreases from top to bottom. The diameter at the top of the adjusting cone 302 is smaller than the diameter at its bottom. This facilitates changing the gap between the adjusting cone 302 and the cavity 102 while also facilitating the falling of materials. Furthermore, the adjusting cone 302 ensures that the falling materials are columnar, which helps to contain dust within the falling material and prevents dust from spreading during the falling process, thus improving the dust suppression effect during material unloading.

[0031] The pipe 2 is welded with an upper mounting plate 201 at the bottom and the discharge hopper 1 is welded with a lower mounting plate 101 at the top. The upper mounting plate 201 and the lower mounting plate 101 are provided with multiple mounting holes at corresponding positions for bolt connection of the upper mounting plate 201 and the lower mounting plate 101, so as to facilitate the installation and disassembly of the pipe 1 and the discharge hopper 1.

[0032] like Figure 9 As shown, an inspection window 103 is also hinged to the discharge hopper 1. One end of the inspection window 103 is hinged to the discharge hopper 1, and the other end can rotate around the hinged end. Opening the inspection window 103 allows for cleaning of the inside of the discharge hopper 1, which is convenient to operate.

[0033] Example 1

[0034] like Figure 2 As shown, an anti-blocking component is also installed inside the cavity 102. This component is located above the adjusting cone 302. By installing the anti-blocking component, it is possible to prevent material from accumulating inside the cavity 102 when it falls into it. Specifically, the anti-blocking component is a connecting plate 306. Both ends of the connecting plate 306 are connected to the inner wall of the discharge hopper 1. The connecting plate 306 is integrally formed from two plates welded at the top and arranged at an angle. Figure 2 As shown, the connecting plate 306 is installed in a triangular shape so that when the material falls, it falls along the upper surface of the connecting plate 306 and does not accumulate in the upper middle area of ​​the cavity 102.

[0035] Example 2

[0036] Based on the above embodiment one, in order to further control the discharge volume of hopper 1, such as Figure 2 As shown, an adjustment component 3 is installed on the connecting plate 306. The bottom of the adjustment component 3 is connected to the top of the adjustment cone 302, and the top is fixedly connected to the pipe 2. The adjustment component 3 controls the adjustment cone 302 to move up and down in the cavity 102. The size of the gap between the adjustment cone 302 and the cavity 102 is changed by the change in the position of the adjustment cone 302.

[0037] Specifically, the adjustment component 3 also includes a vertical rod 309, wherein, as Figure 3 and Figure 4 As shown, the top end of the vertical rod 309 extends into the pipe 2, and its bottom end is fixed to the inner wall of the connecting plate 306, as... Figure 2 As shown, a rack 304 is slidably connected inside the vertical rod 309. The bottom end of the rack 304 is connected to the adjusting cone 302. Further, an mounting block 303 is installed at the top of the adjusting cone 302. The mounting block 303 and the rack 304 are bolted together to facilitate the installation and disassembly of the adjusting cone 302. Through the bolted connection between the mounting block 303 and the rack 304, the adjusting cone 302 moves up and down together with the rack 304. A rotating shaft 310 is also rotatably installed on the discharge hopper 1. The rotating shaft 310 is located behind the vertical rod 309, and both ends of the rotating shaft 310 extend to the outside of the discharge hopper 1. A gear 311 is sleeved on the rotating shaft 310. One end of the rack 304 meshes with the gear 311. The rotation of the gear 311 drives the rack 304 to move up and down linearly inside the vertical rod 309. An opening channel is opened on one side of the vertical rod 309 to facilitate the movement of the rack 304, thereby driving the adjusting cone 302 to move up and down.

[0038] Specifically, the movement of the adjusting cone 302 is determined by the material flow rate in the pipe 2. When the material in the pipe 2 is low, the gear 311 rotates, driving the rack 304 to move downward. At this time, the gap between the adjusting cone 302 and the cavity 102 becomes smaller, thus increasing the area between the upper part of the adjusting cone 302 and the cavity 102. This facilitates the concentration of the material from the pipe 2 into the area between the upper part of the adjusting cone 302 and the cavity 102. When the amount of accumulated material increases, it can form a stable cylindrical drop as it flows out through the smaller gap between the adjusting cone 302 and the cavity 102, better enveloping the dust and improving the dust suppression effect. Conversely, when the flow rate in the pipe 2 is high, the adjusting cone 302 can be moved upward so that when unloading, the material can envelop the dust and drop in a cylindrical shape.

[0039] Furthermore, a triangular reinforcing rib 307 is installed at one end of the vertical rod 309, and the bottom end of the triangular reinforcing rib 307 is connected to the connecting plate 306. A rear cover 308 is installed at the other end of the vertical rod 309, and the rear cover 308 is connected to the vertical rod 309. The gear 311 is set in the rear cover 308. The stability of the connection between the vertical rod 309 and the connecting plate 306 is ensured by the triangular reinforcing rib 307 and the rear cover 308. Furthermore, the top of the rear cover 308 is triangular, and its bottom end is connected to the connecting plate 306. Its function is the same as that of the connecting plate 306, which is to prevent material from accumulating in the cavity 102, so that the material can fall through the upper surface of the rear cover without causing blockage, that is, without affecting the meshing transmission of the gear and rack, ensuring the reliability of the transmission.

[0040] Example 3

[0041] Based on the above embodiment two, in order to facilitate the rotation of gear 311, such as Figures 2-7 As shown, one end of the rotating shaft 310 is connected to an output structure, which is located on one side of the discharge hopper 1. The output structure includes a rotating shaft 301, a worm gear 316 is installed at the bottom of the rotating shaft 301, and a worm wheel 312 is sleeved at one end of the rotating shaft 310. The worm wheel 312 and the worm gear 316 mesh. By rotating the rotating shaft 301, the bottom of the rotating shaft 301 meshes with the worm wheel 312 for transmission. That is, the worm wheel 312 rotates and transmits power to the rotating shaft 310, thereby causing the gear 311 to rotate.

[0042] Furthermore, in order to ensure the stability of the connection between the rotating shaft 310 and the discharge hopper 1, a bearing seat 315 is installed at the connection between the rotating shaft 310 and the discharge hopper 1, and two bearings 314 are sleeved on the rotating shaft 310, with the bearings 314 installed inside the bearing seat 315.

[0043] Furthermore, a protective cover 313 is installed at the bottom of the output structure to protect the connection between the rotating shaft 301 and the rotating shaft 310. In addition, it provides support for the rotating shaft 301. Specifically, for example... Figure 2 and Figure 8 As shown, the protective cover 313 includes an upper cylinder 3131, the bottom of a rotating shaft 301 is located inside the upper cylinder 3131 and the two are rotatably connected, a lower cylinder 3132 passes through the bottom of the upper cylinder 3131, and there is an opening at the connection between the upper cylinder 3131 and the lower cylinder 3132 to facilitate the meshing of the threaded section of the rotating shaft 301 and the worm gear 312. A bushing 3133 is installed at the open end of the lower cylinder 3132, and the rotating shaft 310 extends through the bushing 3133 to the lower cylinder. Inside the cylinder 3132, and with the worm gear 312 located inside the lower cylinder 3132, the rotating shaft 310, the bushing 3133, and the lower cylinder 3132 are all rotatably connected. An L-shaped connecting plate 3134 is installed on one side of the bottom of the lower cylinder 3132. A bottom plate 3135 is symmetrically installed at the bottom end of the L-shaped connecting plate 3134. One end of the bottom plate 3135 is connected to the outer wall of the discharge hopper 1. The bottom plate 3135 provides support for the rotating shaft 301, ensuring the stability of the rotating shaft 301.
