Abstract
Description
Technical Field
[0001] This utility model relates to the field of bulk material conveying technology, and in particular to a bulk material conveying funnel. Background Technology
[0002] Bulk cargo comes in many forms, including coal, ore, bulk grain, bulk cement, and bulk fertilizer. When using a hopper to transport bulk materials, some of these materials have high moisture content, which increases their viscosity and leads to increased flow resistance. This results in excessive friction between the bulk materials and the hopper wall, causing arching and severe blockage inside the hopper.
[0003] To prevent bulk materials from bridging, a vibratory motor is installed on the side wall of the hopper. The vibratory motor drives the hopper wall to vibrate and break the bridging. However, this generates a lot of noise, and the vibration force has a certain impact on the hopper, which may crack the hopper wall and reduce the service life of the hopper.
[0004] Therefore, it is necessary to provide a new bulk material conveying funnel to solve the above problems. Utility Model Content
[0005] The technical problem solved by this utility model is to provide a bulk material conveying hopper that can quickly break up arches and extend the service life of the hopper.
[0006] To solve the above-mentioned technical problems, the bulk material conveying hopper provided by this utility model includes: a hopper, with multiple connecting rods installed at the bottom of the hopper, a fixing ring installed at the top of the connecting rods, an installation box set inside the fixing ring, and a vibration motor installed inside the installation box; a fixing rod is rotatably connected to the top of the installation box, and a conical baffle is installed at the top of the fixing rod, with multiple diversion plates inclined on the surface of the baffle.
[0007] Preferably, a support rod is installed at the bottom of the funnel, and the top of the hollow support rod is fixedly connected to the mounting box.
[0008] Preferably, the funnel is fixedly connected to a connector on its side wall, and the inside of the connector is fixedly connected to a second elastic rubber pad, which is fitted onto the side wall of the support rod.
[0009] Preferably, the side wall of the mounting box is fixedly connected to a first rubber pad in the shape of an annulus, and the first rubber pad is installed inside the fixing ring.
[0010] Preferably, the top surface of the mounting box has an arc-shaped structure, and the mounting box is located in the center inside the funnel.
[0011] Preferably, multiple fixing rings are installed obliquely on the side wall of the fixing rod, and the thickness of the fixing rings gradually decreases from the middle to the edge.
[0012] Compared with related technologies, the bulk material conveying hopper provided by this utility model has the following beneficial effects: This utility model provides a bulk material conveying hopper. When the bulk material moves downwards inside the hopper, it contacts a baffle. The baffle improves the flow pattern of the bulk material inside the hopper, reducing the pressure on the hopper outlet. The conical baffle forms an annular space at its lower part, further reducing the pressure on the bulk material. After contacting the baffle, the bulk material moves along a guide plate, being divided into several streams. This reduces the friction and shear force between the bulk materials, decreasing the probability of arching. Furthermore, the vibrating motor drives the mounting box to vibrate continuously at the hopper outlet, thereby causing the bulk material at the outlet to vibrate continuously, further reducing... The friction and shear forces between small pieces of material allow them to pass quickly through the funnel. The mounting box also causes the material to vibrate without directly vibrating the funnel, thus extending its service life. During the vibration of the mounting box, the fixing rod and the baffle vibrate continuously, increasing the vibration range of the material and accelerating its sliding efficiency on the surfaces of the baffle and the guide plate. As the material moves along the inclined surface of the guide plate, it exerts a thrust on the guide plate and the baffle, causing the baffle and the fixing rod to rotate clockwise, agitating the material inside the funnel and further reducing the friction between the materials, thus preventing them from bridging.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0016] Please see Figures 1 to 4 , Figure 1 A schematic diagram of a preferred embodiment of the bulk material conveying funnel provided by this utility model; Figure 2for Figure 1 The diagram shows an enlarged view of the structure at point A. Figure 3 for Figure 1 The diagram shows an enlarged view of the structure at point B. Figure 4 for Figure 1 The diagram shows a top view of the baffle structure. A bulk material conveying funnel includes a funnel 1. The top surface of the mounting box 3 has an arc-shaped structure. To facilitate the dislodgement of bulk material from the surface of the mounting box 3, the mounting box 3 is located centrally inside the funnel 1. A vibration motor 10 is installed inside the mounting box 3. A fixed rod 5 is rotatably connected to the top of the mounting box 3. A conical baffle 6 is installed at the top of the fixed rod 5. Multiple guide plates 7 are inclinedly arranged on the surface of the baffle 6. When the bulk material moves downward inside the funnel 1, it contacts the baffle 6. The baffle 6 improves the flow pattern of the bulk material inside the funnel 1, reduces the pressure of the bulk material at the outlet of the funnel 1, and the conical baffle 6 forms an annular space at the bottom, further reducing the pressure of the bulk material moving downward. After contacting the baffle 6, the bulk material moves along the guide plates 7, and is divided into... The flow of material reduces friction and shear force between the loose materials, decreasing the likelihood of arching. Furthermore, the vibrating motor 10 drives the mounting box 3 to vibrate continuously at the outlet of the funnel 1, thereby causing the loose material at the outlet of the funnel 1 to vibrate continuously, further reducing friction and shear force between the loose materials and allowing them to pass through the funnel 1 quickly. During the vibration of the mounting box 3, the fixed rod 5 and the baffle 6 also vibrate continuously, increasing the vibration range of the loose material and accelerating the sliding efficiency of the loose material on the surfaces of the baffle 6 and the guide plate 7. As the loose material moves along the inclined surface of the guide plate 7, it exerts a pushing force on the guide plate 7 and the baffle 6, causing the baffle 6 and the fixed rod 5 to rotate clockwise, agitating the loose material inside the funnel 1 and further reducing friction between the loose materials, thus preventing arching.
[0017] The side wall of the mounting box 3 is fixedly connected to a first annular rubber pad 9, which is installed inside the fixing ring 8. Multiple connecting rods 4 are installed at the bottom of the funnel 1, and the fixing ring 8 is installed at the top of the connecting rods 4. The mounting box 3 is set inside the fixing ring 8. When the vibration motor 10 drives the mounting box 3 to vibrate, the first elastic rubber pad 9 is installed between the mounting box 3 and the fixing ring 8. The first rubber pad 9 reduces the restraint on the mounting box 3 and increases the vibration amplitude of the mounting box 3, making it easier for the mounting box 3 to drive the bulk material to vibrate.
[0018] A support rod 2 is installed at the bottom of the funnel 1. The top of the hollow support rod 2 is fixedly connected to the mounting box 3 to provide support for the mounting box 3. A connector 13 is fixedly connected to the side wall of the funnel 1. An elastic second rubber pad 12 is fixedly connected inside the connector 13. The second rubber pad 12 is fitted onto the side wall of the support rod 2. The second rubber pad 12 is installed between the support rod 2 and the connector 13. The second rubber pad 12 provides shock absorption to prevent the support rod 2 from causing the funnel 1 to vibrate violently. The second rubber pad 12 also reduces the constraint of the support rod 2 inside the connector 13, making it easier for the mounting box 3 to cause the support rod 2 to vibrate.
[0019] Multiple fixing rings 8 are installed obliquely on the side wall of the fixing rod 5. During the vibration of the fixing rod 5, the fixing rings 8 vibrate. The fixing rings 8 contact the bulk material, causing the bulk material to vibrate, which facilitates the downward movement of the bulk material. The thickness of the fixing rings 8 gradually decreases from the middle to the edge, increasing the vibration amplitude at the edge of the fixing rings 8 and increasing the vibration amplitude of the bulk material around the fixing rings 8. This facilitates the bulk material to slide over the side wall of the fixing rings 8. When the bulk material slides over the side wall of the obliquely set fixing rings 8, the bulk material generates a thrust on the surface of the fixing rings 8, pushing the fixing rings 8 and the fixing rod 5 to rotate clockwise. This facilitates the rotation and agitation of the bulk material inside the funnel 1 by the fixing rod 5 and the baffle 6, allowing the bulk material to be discharged quickly through the funnel 1.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
