[0028] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Figures 1 to 5 An embodiment of the overturning unloading device for inflammable and explosive materials of the present invention is shown. The overturning unloading device for inflammable and explosive materials of this embodiment comprises a frame 1, an overturning bracket 2 arranged on the frame 1 and a silo 3 arranged below the overturning bracket 2. The overturning bracket 2 is provided with a guide member 21, a positioning assembly 5 for fixing a material carrier 4 on the guide member 21 and a discharge hopper 6 for docking with the material carrier 4. The guide member 21 is arranged in a water tank 22. The water tank 22 is provided with a drain port 23 and a water injection port (not shown, for example, the water injection port 23 and the drain port can be arranged at both ends of the water tank 22). A collecting member 7 is arranged below the drain port 23, and a discharge valve 61 is arranged at the outlet of the discharge hopper 6. Among them, the guide member 21 can be, for example, a guide rail or a guide groove, etc., the material carrier 4 can be, for example, a medicine basket, etc., the collecting member 7 can be, for example, a collection tray, a collection hopper, etc.; the discharge valve 61 preferably adopts a pinch valve.

[0030] The present invention discloses a flipping unloading device for flammable and explosive materials. When working, the material carrier 4 moves along the guide member 21 on the flipping bracket 2 until it is accurately docked with the upper discharge hopper 6. After the material carrier 4 is in place, the positioning component 5 fixes the material carrier 4 on the guide member 21 to prevent the material carrier 4 from moving during subsequent flipping. Then the flipping bracket 2 flips downward until the outlet of the discharge hopper 6 docks with the silo 3 below. At this time, the discharge valve 61 opens, and the material in the material carrier 4 enters the silo 3 through the discharge hopper 6. The structure is simple, the degree of automation is high, the reliability is good, and it is conducive to reducing labor intensity and improving efficiency. For details, see Figure 5 The guide member 21 is arranged in the water tank 22. The water in the water tank 22 can clean the dust attached to the guide member 21 and keep the guide member 21 moist, thereby preventing the material carrier 4 from squeezing the dust and reducing the friction between the material carrier 4 and the guide member 21, thereby greatly reducing the risk of explosion. When the flip bracket 2 flips, the water in the water tank 22 can be discharged through the drain port 23 and collected by the collecting member 7 below; when it is necessary to flip and unload again, after the flip bracket 2 is reset, water can be refilled into the water tank 22 through the water injection port, and then the next material carrier 4 moves into place along the guide member 21.

[0031] See Figure for details Figure 1 and Figure 2In this embodiment, the positioning assembly 5 includes a positioning seat 51 arranged on the flip bracket 2, a positioning cylinder 52 arranged on the positioning seat 51, and a positioning block 53 connected to the piston rod of the positioning cylinder 52, and at least one positioning slot 54 is provided on the positioning block 53. After the material carrier 4 is in place, the positioning rod of the positioning cylinder 52 extends, so that the positioning slot 54 on the positioning block 53 clamps the roller 41 on the material carrier 4, thereby effectively limiting the movement of the material carrier 4 along the guide member 21, and the structure is simple and reliable. Preferably, the specific number of the positioning slots 54 is consistent with the number of rollers 41 on the material carrier 4, and each roller 41 is clamped one by one. Compared with the motor, the positioning cylinder 52 is more suitable for energetic materials, which is helpful to avoid explosion.

[0032] As a preferred embodiment, a guiding structure is provided between the positioning seat 51 and the positioning block 53 (not shown in the figure, for example, it may be a guide shaft provided on the positioning block 53 and a guide sleeve provided on the positioning seat 51, or a guide rail and a slider, etc.), which can provide a guiding effect for the movement of the positioning block 53 to prevent displacement.

[0033] As a preferred embodiment, the positioning cylinder 52 is arranged in the vertical direction, which can effectively utilize the space in the height direction of the flip bracket 2 and reduce the volume of the flip bracket 2. Of course, in other embodiments, the positioning cylinder 52 can also be arranged horizontally, which can also clamp the roller 41, but it will cause the width direction of the flip bracket 2 to increase.

[0034] See Figure 2 In this embodiment, a hydraulic motor 11 is provided on one side of the frame 1, and the hydraulic motor 11 is connected to the flip bracket 2 through a driving shaft 12. A driven shaft 13 is provided on the other side of the frame 1 opposite to the frame 1, and the driven shaft 13 is connected to the flip bracket 2. The driving shaft 12 and the driven shaft 13 can realize the stable installation of the flip bracket 2 on the frame 1. The hydraulic motor 11 can drive the flip bracket 2 to rotate forward and reverse through the driving shaft 12. Compared with the motor, the hydraulic motor 11 is more suitable for energetic materials and is conducive to avoiding explosion.

[0035] Furthermore, in this embodiment, an inflatable sealing ring (not shown in the figure) is provided at the joint between the discharge hopper 6 and the material carrier 4. After the material carrier 4 reaches below the discharge hopper 6, the inflatable sealing ring is inflated and expanded, thereby effectively sealing the gap between the material carrier 4 and the discharge hopper 6, ensuring sealing and preventing material leakage.

[0036] See Figure 4 In this embodiment, the silo 3 is provided with a feed pipe 31, and the feed pipe 31 is provided with an inverted cone-shaped docking piece 32 for docking with the outlet of the discharge hopper 6. The inverted cone-shaped docking piece 32 is convenient for docking with the outlet of the discharge hopper 6, so that the material in the discharge hopper 6 can smoothly enter the feed pipe 31, and the structure is simple and effective.

[0037] Furthermore, in this embodiment, the feed pipe 31 is a retractable pipe and is equipped with a lifting drive cylinder 33, and the docking piece 32 is a flexible docking piece. After the material carrier 4 and the discharge hopper 6 are turned over, the lifting drive cylinder 33 drives the feed pipe 31 to rise, so that the docking piece 32 is tightly docked with the outlet of the discharge hopper 6, which is beneficial to prevent material leakage. The use of a flexible docking piece is beneficial to improving the sealing performance on the one hand, and on the other hand, it is beneficial to prevent rigid collisions that cause damage to the discharge hopper 6 and the docking piece 32. The feed pipe 31 can be an elastic pipe or a corrugated pipe to avoid hindering the lifting and lowering movement of the docking piece 32. Compared with a motor, the lifting drive cylinder 33 is more suitable for energetic materials and is beneficial to avoiding explosions.

[0038] Furthermore, in this embodiment, a conical guide 34 is provided below the entrance of the silo 3, and a plurality of drop holes 35 are provided on the guide 34. After the material passes through the entrance of the silo 3, it can be guided to the surroundings by the guide 34, and a part of the material can continue to fall through the drop holes 35, which is conducive to evenly distributing the material in the silo 3, and at the same time can slow down the descending speed of the material, thereby reducing the friction and collision between the materials, which is conducive to reducing the risk of combustion and explosion for energetic materials.

[0039] Furthermore, in this embodiment, a screen 36 capable of conducting static electricity is provided in the silo 3, and the guide member 34 is provided on the screen 36. The screen 36 is used to reduce the falling speed of the material, thereby reducing the friction and collision between the materials, and on the other hand, it can also conduct static electricity generated by friction between the materials to avoid static electricity accumulation, and for energetic materials, the risk of combustion and explosion can be further reduced.
