Description

Technical Field

[0001] The utility model relates to the technical field of mining chutes, in particular to a funnel assembly for a chute. Background Art

[0002] A chute is a trough usually on the ground that transports materials from high to low. It is mainly used in small open-pit mines. In large and medium-sized open-pit mines, chutes are often used in conjunction with chutes. A funnel is usually set at the bottom or outlet of the chute to receive materials that slide down from the chute. The funnel is usually connected to a conveyor belt, pipeline or other conveying equipment. Through the transition effect of the funnel, the material can smoothly enter the subsequent equipment for processing or transportation, thereby improving the continuity and stability of the entire system.

[0003] The existing funnel with a blockage detection function (such as publication number CN205346156U) has a movable door hinged on the side wall of the funnel, and a limit switch is set in the vicinity of the movable door. The limit switch is connected in series with the belt conveyor control circuit. When the funnel is blocked, the material pushes the movable door open and is discharged outward. When the movable door is pushed open, the limit switch is triggered, causing the belt conveyor to automatically stop for maintenance, thereby solving the blockage problem of the funnel.

[0004] However, the existing funnel with a blockage detection function is easily affected by the properties of the material. When encountering sticky materials, the material discharge speed is slow, and the material is very likely to accumulate in the funnel rather than get blocked. At this time, the movable door will still be pushed open and trigger the limit switch, thereby causing the belt conveyor to stop by mistake, seriously affecting work efficiency. In addition, the movable door is hinged at the top. When the funnel is pushed open by the accumulated (non-blocked) sticky material, the material will be discharged outward, which is very likely to cause material loss and pollution. Utility Model Content

[0005] In order to solve the technical problem in the above background technology that the existing funnel with a blockage detection function is easily affected by the properties of the material, causing the belt conveyor to stop accidentally and causing material loss and pollution, the utility model provides a funnel assembly for a chute.

[0006] The technical solution of this utility model is as follows:

[0007] The utility model provides a funnel assembly for a chute, comprising a funnel arranged between the chute and the belt conveyor, the funnel comprising a funnel body, a material leakage port being opened on the side wall of the funnel body, a movable door hinged at the bottom being provided at the material leakage port, the upper part of the movable door being connected to the funnel body by a tension spring, a vibrator being fixedly provided on the outer wall of the funnel, a detection mechanism being provided on one side of the funnel, the detection mechanism comprising a first laser sensor and a second laser sensor, the first laser sensor being located above the second laser sensor, the first laser sensor being connected to a control circuit of the vibrator, and the second laser sensor being connected to a control circuit of the belt conveyor, when the sticky material is in an accumulated state, the sticky material will push the movable door to open outward, the upper part of the movable door will move outward, the movable door will support the material and trigger the first laser sensor, the vibrator will work, and under the vibration and knocking action of the vibrator, the flow and discharge speed of the sticky material will be accelerated, the accumulation of the sticky material will be reduced, and the loss and pollution of the material will be avoided.

[0008] Preferably, a flange is fixedly provided on the peripheral side of the movable door, and the flange extends toward the interior of the funnel body to improve the supporting capacity of the movable door for materials.

[0009] Preferably, a material leakage port is provided on at least one side wall of the funnel body, so that the anti-blocking ability of the funnel body can be adjusted according to actual needs.

[0010] Preferably, the lower portion of the movable door is hinged to the side wall of the funnel body through a hinge, so that the upper portion of the movable door opens outward, making it easier to use the movable door to support the material.

[0011] Preferably, the vibrator is fixedly arranged on the outside of the side wall without the leakage port, which facilitates the installation and use of the vibrator.

[0012] Preferably, the shape and size of the movable door match the material leakage opening, and the movable door can be used to block the material leakage opening to avoid leakage of materials during normal operation.

[0013] It can be seen from the above technical solutions that the advantages of the present invention are:

[0014] 1. The material will push the movable door to open outward, and the upper part of the movable door will move outward, and trigger the laser sensors at different positions according to the opening and closing angle. The laser sensors at different positions will control the start and stop of the vibrator and the belt conveyor accordingly. When sticky materials accumulate, the vibrating action of the vibrator can accelerate the flow and discharge speed of the sticky materials, avoiding the accidental shutdown of the belt conveyor and affecting the work efficiency. When the sticky materials accumulate too much or the funnel is blocked, the belt conveyor can be stopped for easy maintenance. It can adapt to different working conditions and has strong overall adaptability.

[0015] 2. The lower part of the movable door is hinged, which can play a supporting role and effectively reduce the amount of material leakage. The movable door is fixed with a flange on the side, which extends toward the inside of the funnel body, effectively improving the supporting capacity of the movable door for the material.

[0021] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in the specific embodiments. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this patent.

[0022] In a typical embodiment of the present invention, Figure 1-Figure 2 As shown, a funnel assembly for a chute is proposed, comprising: a funnel and a detection mechanism arranged between the chute and the belt conveyor. The funnel plays a collecting and transition role, and the detection mechanism is located on one side of the funnel and is used to detect the opening angle of the movable door 2.

[0023] like Figure 2 As shown, the funnel includes a funnel body 1, a movable door 2, a tension spring 3 and a vibrator 7, wherein the funnel body 1 is a variable diameter structure, and both ends of the funnel body 1 are open, and a leakage port 8 is provided on the side wall of the funnel body 1. When the material is blocked in the funnel body 1, it will be discharged outward through the leakage port 8.

[0024] It is understandable that the funnel body 1 can have a material leakage opening 8 on one side wall, or can have material leakage openings 8 on multiple side walls, and the specific number of openings is not limited here.

[0025] The movable door 2 is hinged on the side wall of the funnel body 1 where a material leakage port 8 is provided, and the shape and size of the movable door 2 match the material leakage port 8. Specifically, the lower part of the movable door 2 is hinged to the side wall of the funnel body 1 through a hinge 9, and the upper part of the movable door 2 is connected to the inner wall of the funnel body 1 through a tension spring 3, so that when the material is discharged outward through the material leakage port 8, the movable door 2 will be pushed open. When the movable door 2 is not pushed by the material, it will be reset under the action of the tension spring 3.

[0026] It is understandable that the funnel body 1 can be a frustum, a circular frustum or other structure, the leakage port 8 and the movable door 2 can be a rectangular, fan-shaped or other structure, and the specific structural form can be determined according to actual design requirements, and no excessive restrictions are made here.

[0027] Since the movable door 2 is a lower hinged structure, when the funnel is used to discharge viscous materials, and the viscous materials are in an accumulated (non-blocked) state due to their slow flow and discharge speed, the viscous materials will push the movable door 2 to open outwards. Supported by the movable door 2, the materials will not be discharged directly outwards, thereby avoiding material loss and pollution.

[0028] In order to improve the supporting capacity of the movable door 2 for materials in a non-blocked state, a flange can be fixedly provided on the peripheral side of the movable door 2 , and the flange extends toward the interior of the funnel body 1 .

[0029] A vibrator 7 is fixedly provided on the outside of the side wall of the funnel body 1 where the material leakage port 8 is not provided, so as to accelerate the discharge speed of the material in the funnel body 1 through the vibration of the vibrator 7 and avoid the accumulation of the material in the funnel body 1 due to slow flow and discharge speed.

[0030] The detection mechanism includes two laser sensors 5 , which are arranged one above the other and are fixedly mounted on a fixing frame 4 . The two laser sensors 5 are located on one side of the funnel to detect the opening angle of the movable door 2 .

[0031] Specifically, the two laser sensors 5 are the first laser sensor and the second laser sensor, respectively. The first laser sensor is located above the second laser sensor, the first laser sensor is connected in series with the control circuit of the vibrator 7, and the second laser sensor is connected in series with the control circuit of the belt conveyor, so that the operation control of the corresponding device can be realized according to the actual opening angle of the movable door 2.

[0032] The specific working principle is:

[0033] When conveying viscous materials, due to their own properties, the flow and discharge speed of viscous materials in the funnel body 1 are slow, and the viscous materials are very likely to accumulate rather than be blocked. When the viscous materials are in an accumulated state, after they accumulate to a certain height, the viscous materials will push the movable door 2 to open outward, and the upper part of the movable door 2 moves outward. At this time, the movable door 2 supports the materials and triggers the first laser sensor, and the vibrator 7 works. Under the vibration and beating action of the vibrator 7, the flow and discharge speed of the viscous materials are accelerated, and the accumulation of the viscous materials is reduced. The movable door 2 is pulled back to its original position by the tension spring 3, and the materials supported by the movable door 2 return to the funnel body 1, avoiding the loss and pollution of the materials. Among them, when the opening angle of the movable door 2 is reduced / reset, the movable door 2 will trigger the first laser sensor again, and the vibrator 7 stops working;

[0034] When too much sticky material accumulates in the funnel body 1 or the funnel is blocked, the material will push the movable door 2 to open outward at a large angle. The movable door 2 will trigger the first laser sensor and the second laser sensor in turn, turning on the vibrator 7 and stopping the belt conveyor to facilitate the maintenance of the funnel. When the movable door 2 is reset, the vibrator 7 stops working and the belt conveyor restarts.

[0035] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
