[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. In the absence of conflict, the embodiments and features in the embodiments of the utility model can be combined with each other. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] Embodiment 1

[0025] Figure 1 An embodiment of a chute structure of the utility model is shown, see Figure 1 In this embodiment, the chute structure includes: a supporting foundation 1, and a vertical shaft 2 and a transfer assembly 3 arranged on the supporting foundation 1.

[0026] Among them, see Figure 1 The transfer assembly 3 is provided with a chute 31 installed on the supporting foundation 1. One end of the chute 31 is connected to the inner bottom of the shaft 2, and the other end of the chute 31 extends to one side of the supporting foundation 1. The material at a high position is put into the top end of the shaft 2. The material falls into one end of the chute 31 under the action of gravity, so that the bottom surface of the chute 31 has a slope, and the material can be guided to the low position at the other end of the chute 31 by its own weight; a truss 32 is provided on one side of the top of the chute 31 adjacent to the shaft 2, and the truss 32 is provided on the other side of the chute 31. 2 is provided with a mounting hole 321. When the shaft 2 is blocked, one end of the baffle 33 extends into the chute 31 through the mounting hole 321 to partially block the end of the chute 31 adjacent to the shaft 2. The maintenance personnel enter the end of the chute 31 adjacent to the shaft 2. When the blocking object in the shaft 2 partially falls off or collapses on a large scale, the maintenance personnel can hide on the side of the baffle 33 away from the shaft 2 to avoid being hit or buried by the falling objects. When the maintenance process is completed, the baffle 33 is taken out to allow the chute 31 to move normally.

[0027] Further, see Figure 2The mounting hole 321 is a strip hole that matches the cross section of the baffle 33 along its movable direction. The radial direction of the mounting hole 321 is perpendicular to the radial direction of the slide groove 31. One radial end of the mounting hole 321 is adjacent to one of the side walls of the slide groove 31, and the other radial end of the mounting hole 321 has a preset distance from the other side wall of the slide groove 31, so that after the baffle 33 is installed, there is a right-angle structure blind angle area between the end face of the baffle 33 away from the shaft 2 and one of the side walls of the slide groove 31, which can further improve the life safety of maintenance personnel.

[0028] Optionally, the preset distance is greater than zero and does not exceed half of the width of the chute 31 , so as to ensure that after the baffle 33 is installed, there is still an area in the chute 31 for materials to pass through.

[0029] Further, see Figure 2 The area on the bottom surface of the slide groove 31 facing the mounting hole 321 and the side wall of the slide groove 31 adjacent to the mounting hole 321 are each provided with at least one group of latches 311. Each group of latches 311 has two latches, which are respectively located on both sides of the radial line of the mounting hole 321. Each group of latches 311 respectively clamps the bottom edge or one of the side edges of the baffle 33 to prevent the baffle 33 from swinging around the radial line of the mounting hole 321, thereby further improving the stability of the baffle 33 after being installed in the slide groove 31.

[0030] Furthermore, there is a preset angle between the top surface of the supporting foundation 1 and the horizontal plane, the bottom surface of the slide 31 is flush with the bottom surface of the shaft 2 and parallel to the top surface of the supporting foundation 1, so that the bottom surface of the slide 31 has a slope, and the end of the slide 31 adjacent to the shaft 2 is in a high position, and the end of the slide 31 away from the shaft 2 is in a low position.

[0031] Optionally, the value of the preset angle is [10°, 15°], and the value of the preset angle is determined according to the distance from the shaft 2 to the space on one side of the chute 31 away from the shaft 2. The longer the distance, the larger the value of the preset angle.

[0032] Optionally, the supporting foundation 1 is a concrete cast structure with a steel frame arranged inside, so that the supporting foundation 1 has sufficient supporting performance.

[0033] Optionally, a plurality of support rods are provided on the end surfaces of the two side plates of the slide groove 31 that are away from each other, and on the end surface of the bottom plate that is adjacent to the supporting base 1 , so as to improve the stability of the structure of the slide groove 31 .

[0034] In this embodiment, materials at a high position are put into the top end of the shaft 2, and the materials fall into the chute 31 adjacent to the end of the shaft 2 under the action of gravity. The chute 31 has a certain slope, and the materials roll or slide to the space of the chute 31 away from the side of the shaft 2 under the action of their own gravity, thereby completing the process of transporting the materials from a high position to a low position; when a blockage occurs inside the shaft 2, one end of the baffle 33 passes through the truss 32 and is inserted into the chute 31 to partially block the end of the chute 31 adjacent to the shaft 2, so that the inside of the chute 31 adjacent to the end of the shaft 2 has a dead angle for material impact, so that maintenance personnel can avoid being hit or buried by the blockage in the shaft 2 when it partially falls or completely collapses.

[0035] Embodiment 2

[0036] In order to control the output of the chute 31 away from the end of the shaft 2, based on the first embodiment, see Figure 3 The chute mechanism also includes a gate assembly 4, which is provided with a door plate 41, a connecting rod 42 and a hydraulic telescopic rod 43.

[0037] Among them, see Figure 3 The door panel 41 is suspended in the air and covers the end of the chute 31 away from the shaft 2. The top edge of the door panel 41 is connected to the side wall of the connecting rod 42. The two axial ends of the connecting rod 42 are respectively rotatably connected to the wall of the space on the side of the chute 31 away from the shaft 2. The door panel 41 is driven to rotate around the axis of the connecting rod 42 to change the opening of the chute 31 away from the shaft 2. In this way, the material output of the chute 31 away from the shaft 2 can be controlled.

[0038] Further, see Figure 3 The end surface of the door panel 41 away from the slide groove 31 is rotatably connected to one end of a hydraulic telescopic rod 43, and the other end of the hydraulic telescopic rod 43 extends in the direction of the slide groove 31 away from the shaft 2, and is rotatably connected to the wall of the space on one side of the slide groove 31 away from the shaft 2. Controlling the extension or contraction of the hydraulic telescopic rod 43 can drive the door panel 41 to rotate around the axis of the connecting rod 42.

[0039] Optionally, the axis of the connecting rod 42 is parallel to the bottom surface of the sliding groove 31 and perpendicular to the radial line of the sliding groove 31 , and the telescopic direction of the hydraulic telescopic rod 43 is perpendicular to the axis of the connecting rod 42 .

[0040] Optionally, when the hydraulic telescopic rod 43 is at its maximum extension range, the end face of the door panel 41 away from the hydraulic telescopic rod 43 completely covers the end of the slide 31 away from the shaft 2, and when the electric hydraulic telescopic rod 43 is at its minimum extension range, the opening of the slide 31 away from the end of the shaft 2 is the largest.

[0041] It should be noted that the present embodiment focuses on the working principle of the hydraulic telescopic rod 43.

The present embodiment and the accompanying drawings have given the installation position or area of ​​the hydraulic telescopic rod 43, and the specific structure of the hydraulic telescopic rod 43 will not be repeated.

[0042] In this embodiment, the hydraulic telescopic rod 43 is controlled to retract or extend, which can drive the door panel 41 to rotate clockwise or counterclockwise around the axis of the connecting rod 42 by a certain angle. In this way, the opening of the chute 31 away from the end of the shaft 2 can be changed, thereby controlling the material output efficiency of the chute 31 away from the end of the shaft 2.

[0044] In order to prevent the material from accumulating in the chute 31 and causing blockage, based on the first embodiment, see Figure 3 The chute structure also includes a vibration component 5, which is provided with a bracket 51 and a vibration motor 52.

[0045] Among them, see Figure 3 The bracket 51 is arranged at the top of the chute 31 and is located on the side of the truss 32 away from the shaft 2. The vibration motor 52 is arranged on the bracket 51. When the material stagnates or accumulates in the chute 31, the vibration motor 52 is controlled to work. The vibration from the vibration motor 52 will be transmitted to the bottom surface of the chute 31 through the bracket 51 and the side wall of the chute 31, thereby vibrating the material in the chute 31, so that the material stagnant or accumulated in the chute 31 continues to roll or slide, thereby avoiding the accumulation of materials inside the chute 31 and causing blockage.

[0046] It should be noted that the present embodiment focuses on the working principle of the vibration motor 52. The specific structure of the vibration motor 52 is not the focus of the present embodiment and is prior art. The present embodiment and the accompanying drawings have given the installation position or area of ​​the vibration motor 52, and the specific structure of the vibration motor 52 will not be repeated.

[0047] In this embodiment, the vibration motor 52 is controlled to do work, and the vibration generated by the vibration motor 52 is transmitted to the material stagnant or accumulated at the bottom of the chute 31 through the bracket 51 and the chute 31, and the material stopped or accumulated in the chute 31 is driven by the vibration to continue rolling or sliding to the space of the chute 31 away from one end of the shaft 2.
