[0034] The present application is further described in detail below in conjunction with the accompanying drawings.

[0035] The embodiment of the present application discloses an environmentally friendly concrete automatic vending system.

[0036] Example 1: Combination Figure 1 and Figure 3 As shown, it includes a plurality of storage bins 1 for storing different raw materials. Sand, aggregate, cement powder and other materials are stored in different storage bins 1. An upper sealed cabin 2 and a lower sealed cabin 3 are fixedly connected to the upper and lower parts of the storage bin 1 respectively. A loading mechanism 4 for feeding materials into the storage bin 1 is arranged on one side of the storage bin 1. A discharge pipe 5 located in the lower sealed cabin 3 is arranged at the bottom of the storage bin 1. An electromagnetic valve for controlling on and off is arranged on the discharge pipe 5. A batching mechanism 6 for proportioning and stirring the raw materials output by the discharge pipe 5 is also arranged in the lower sealed cabin 3.

[0037] Combination Figure 1 and Figure 2As shown, the loading mechanism 4 includes a discharge hopper 7, which is arranged on the ground. A cover plate is hinged on the discharge hopper 7. The cover plate usually covers the opening of the discharge hopper 7. When unloading is required, the cover plate is opened, and a spray pipe is fixed on the inner wall of the cover plate. A water pump and a solenoid valve are connected to the spray pipe. A spray head is connected to the end of the spray pipe. When unloading, large dust will be generated. At this time, the spray can be turned on as needed to reduce the dust. A ramp is arranged on one side of the discharge hopper 7. When the transport vehicle is unloading, The transport vehicle drives onto the ramp platform to unload, so that both large and small vehicles can unload smoothly; an elevator 8 is provided on the other side of the unloading hopper 7 relative to the ramp platform, and the elevator 8 is connected to the unloading hopper 7. The elevator 8 can be a screw conveyor or a pneumatic conveyor, etc. The bottom surface of the unloading hopper 7 is inclined so that the material and mortar in the hopper are gathered at the elevator 8, and the material is lifted when the elevator 8 is working. The storage bin 1 is set on the ground and is located on the side of the elevator 8 away from the unloading hopper 7.

[0038] Since there are multiple storage bins 1, when feeding materials into each storage bin 1 through the same elevator 8, it is necessary to separate the materials according to the types of raw materials so that the materials lifted by the elevator 8 can be smoothly input into the corresponding storage bin 1. Therefore, a material separation component 9 is provided for material separation.

[0039] The discharge end of the elevator 8 penetrates into the upper sealed cabin 2, and the material distribution component 9 is arranged in the upper sealed cabin 2. The material distribution component 9 includes a layer of conveyor belt 10 located below the discharge port of the elevator 8, and two layers of conveyor belts 11 for receiving materials are arranged below both ends of the first layer of conveyor belt 10. The conveyor belt is provided with multiple layers and the lower conveyor belt is located below both ends of the upper conveyor belt 10. In this embodiment, the conveyor belt is provided with three layers, and the raw material inlet of each storage bin 1 is located below each end of the lowest conveyor belt.

[0040] like Figure 3 As shown, the batching mechanism 6 includes a weighing hopper 14 arranged below the discharge pipe 5 for weighing the material, and a transmission component 15 is arranged below each weighing hopper 14. The raw materials discharged from the discharge pipe 5 first fall into the weighing hopper 14 for weighing, and the weighed raw materials are then discharged and fall onto the transmission component 15. A small mixer 16 for stirring the raw materials is arranged below the discharge end of the transmission component 15, and a water inlet pipe is arranged above the inlet of the small mixer 16, and a solenoid valve is also arranged on the water inlet pipe to control the water inlet; after each discharge pipe 5 stops discharging materials, the transmission component 15 keeps conveying to ensure that no raw materials remain on the transmission component 15, and the small mixer 16 starts working at the same time when the discharge pipe 5 starts discharging materials. It is selected whether to supply water to the small mixer 16 through the water inlet pipe according to whether the customer needs dry mixing materials or wet mixing materials, and the mixing materials are output as needed after the mixing is completed.

[0041] The transmission component 15 in this embodiment is a conveyor belt 19, which is located below each weighing bucket 14, one end of the conveyor belt 19 is located above the inlet of the small mixer 16, and a discharge chute 20 is provided below the other end. The discharge chute 20 passes through the lower sealed cabin 3, and the raw materials in the storage bin 1 are discharged from the discharge pipe 5 into the weighing bucket 14. After being weighed by the weighing bucket 14, the raw materials are arranged and fall onto the conveyor belt 19. According to needs, the working conveyor belt 19 transports the raw materials thereon to above the inlet of the small mixer 16, and the raw materials fall into the small mixer 16 for mixing, or directly transports the raw materials thereon to the discharge chute 20 for output.

[0042] A storage hopper 17 is provided below the discharge port of the small mixer 16, and a delivery pipe 18 (not shown in the figure) is sealed and connected to the lower outlet of the storage hopper 17, and a solenoid valve is also provided on the delivery pipe 18, and the delivery pipe 18 passes through the lower sealed cabin 3; the mixing material discharged from the small mixer 16 first falls into the storage hopper 17, and the opening of the storage hopper 17 is relatively large to prevent the material from falling outside the storage hopper 17. The mixing material is stored in the storage hopper 17, so that the small mixer 16 can be emptied for the next part of mixing, and the mixing material in the storage hopper 17 is output through the delivery pipe 18, so that the mixing material is output stably.

[0043] Since cement powder is a powder material, it is easy to be blown away by the wind if it is directly output, and dust is also relatively large. Therefore, a bagging mechanism 25 for packaging the cement powder is also provided in the lower sealed cabin 3. The cement powder is bagged and then sold retail. An output channel 34 fixed in the lower sealed cabin 3 is provided below the bagging mechanism 25. The output channel 34 passes through the lower sealed cabin. After the cement powder is packaged into bags by the bagging mechanism 25, it falls into the output channel 34 for output.

[0044] Combination Figure 3 and Figure 4As shown, a horizontal slide rail 26 is fixedly provided in the lower sealed cabin 3, and a weighing bucket 14 for weighing cement powder is slidably connected to the horizontal slide rail 26 and can move horizontally. The bagging mechanism 25 includes winding rollers 27 symmetrically arranged on both sides below the weighing bucket 14 after translation, and a material strip for making packaging bags is wound on the winding rollers 27. Two pairs of rubber rollers are arranged below the middle of the two winding rollers 27. The rubber rollers can also be other rollers. The rubber rollers are driven by a motor, and the two pairs of rubber rollers clamp the two side edges of the two material strips respectively, so that the two side edges of the two material strips are kept together and drive the two material strips to be transmitted downward. An edge compounding device 28 is arranged directly below the two pairs of rubber rollers to compound the edges of the two material strips together. This edge compounding device 28 can The sewing machine can also be a heat press, etc. After being processed by the edge compounding device 28, the two side edges of the two material strips are fixed together, and the material strips are transmitted vertically downward; a composite cutting component 29 is arranged below the edge compounding device 28, and the composite cutting component 29 includes two layers of upper and lower horizontal compounding devices 30 and a shearing device 31. The horizontal compounding device 30 can be a sewing machine or a heat press, etc. The two layers of horizontal compounding devices 30 cut the material strips, and the shearing device 31 can be a mechanism such as scissors and a cutter. The shearing device 31 cuts the material strips at the position between the two layers of horizontal devices, so that the upper end opening of the material bag below the composite cutting component 29 is closed, and the lower end opening of the material bag above the composite cutting component 29 is closed, thereby achieving bag sealing.

[0045] The two material strips are first made into bags with upper openings by the cooperation of the edge compounding equipment 28 and the compound cutting assembly 29. At this time, the cement powder in the weighing bucket 14 is discharged into the bag from the upper opening of the bag. After a certain amount of cement powder is discharged into the bag, the compound cutting assembly 29 seals the upper opening of the bag and the lower opening of the next bag, and cuts off the bag filled with cement powder. The bag filled with cement powder is supported on the conveying mechanism. After the bag is cut off, it is directly poured onto the conveying mechanism and sent away for output.

[0046] Since the cement powder in the weighing hopper 14 is not easy to be poured directly into the bag with an opening at the upper end, a guide hopper 32 is fixedly provided between the weighing hopper 14 and the bagging mechanism 25. The guide hopper 32 is located directly below the weighing hopper 14 after translation. After the cement powder is weighed in the weighing hopper 14, the cement powder is directly discharged into the guide hopper 32. The lower end opening of the guide hopper 32 is sealed and connected with a vertical guide pipe 33. The guide pipe 33 slightly supports two material belts between two pairs of rubber rollers and extends downward to a position below the edge composite device 28 and above the composite cut-off assembly 29, so that the water-cement powder is directly input into the formed bag for bagging, thereby preventing too much cement powder from being unable to enter the bag when it is discharged directly from the weighing hopper 14.

[0047] like Figure 1As shown, since the sand and gravel themselves carry mortar, mortar will also be produced when water is sprayed to reduce dust, in order to prevent the mortar from polluting the surrounding environment, a mortar recycling mechanism 35 is provided to recycle the mortar.

[0048] The mortar recycling mechanism 35 includes a drain outlet 36 arranged on the bottom side wall of the elevator 8. The water in the discharge hopper 7 and the elevator 8 will gather at the bottom of the elevator 8 and be discharged from the drain outlet 36. In order for the material to be discharged from the drain outlet 36, a filtering device 37 (not shown in the figure) is also provided at the drain outlet 36 to block the material. A first drain pipe 38 is connected to the drain outlet 36. A water storage space 42 is provided under the ground surface. The first drain pipe 38 is connected to the water storage space 42, so the first drain pipe 38 can transport the mortar at the bottom of the elevator 8 to the water storage space 42 for storage.

[0049] A drainage hole 39 (not shown in the figure) is provided on the side wall of the discharge pipe 5 of some storage bins 1. For example, a storage bin 1 for storing sand and a storage bin 1 for storing sand and gravel aggregates are also fixedly provided with a filter screen 40 (not shown in the figure) at the drainage hole 39. The filter screen 40 blocks the material, and a second drainage pipe 41 is connected to the drainage hole 39. The second drainage pipe 41 is also connected to the water storage space 42. The mortar on the material in the storage bin 1 gradually gathers in the discharge pipe 5 and then is input from the drainage hole 39 through the second drainage pipe 41 into the water storage space 42 for storage.

[0050] The filtering device 37 includes a fixed filter screen 43 (not shown in the figure) fixedly connected to the side wall of the elevator 8. The fixed filter screen 43 completely blocks the drain port 36, and the mortar flows into the first drain pipe 38 from the mesh of the fixed filter screen 43. A lifting plate 44 (not shown in the figure) is also slidably connected to the outer side of the fixed filter screen 43. The lifting plate 44 is controlled by a power motor 45 (not shown in the figure). When the lifting plate 44 is lowered, it completely blocks the drain port 36, thereby preventing the powder from being discharged from the drain port 36. When the mortar needs to be discharged, the power motor 45 is controlled to lift the lifting plate 44. The machine 45 then controls the lifting plate 44 to rise to open the drain port 36. Two slide rails are arranged on the outer wall of the elevator 8. The two slide rails respectively press the two sides of the lifting plate 44 so that the lifting plate 44 can only slide along the outer wall of the elevator 8. The power motor 45 is fixed on the outer wall of the elevator 8. A gear is arranged on the rotating shaft of the power motor 45. A groove is arranged on the side surface of the lifting plate 44 facing away from the elevator 8. The bottom of the groove is arranged with teeth and meshes with the gear, so that the lifting plate 44 can be controlled to move up and down when the power motor 45 is working.

[0051] The spray pipe on the cover plate is connected to the water storage space 42 , and the water storage space 42 is connected to a water supply pipe, and a float valve is connected to the water supply pipe, so that the water level in the water storage space 42 is maintained at a certain level.

[0052] The upper surface of the water storage space 42 is arranged in a funnel shape, and a water inlet channel is arranged at the bottom of the funnel shape to connect to the water storage space 42. A filter is fixed in the water inlet channel to block impurities, and a coarse sand layer, a fine sand layer and a soil layer are laid from bottom to top above the water storage space 42. Rainwater is filtered and gathered through the soil layer, the fine sand layer and the coarse sand layer and flows into the water storage space 42, so that the water in the water storage space 42 can be replenished to reduce water consumption.

[0053] Example 2: Figure 5 As shown, the difference between this embodiment and embodiment 1 is that the material distribution component 9 includes a feed pipe 12 rotatably connected to the discharge end of the elevator 8, and the feed pipe 12 is transmission-connected with a control motor 13 for controlling its rotation. As needed, the control motor 13 controls the feed pipe 12 to rotate to align with the inlets of different storage bins 1, so that the material transmitted by the feed pipe 12 can fall into the corresponding storage bin 1.

[0054] Example 3: Figure 6 As shown, the difference between this embodiment and embodiment 1 is that the transmission component 15 in this embodiment includes a fixed frame 21 fixed below the storage bin 1, the fixed frame 21 is fixedly connected in the lower sealed cabin 3, and a material receiving pipe 22 with a vertical rotation axis and a servo motor 23 driving the material receiving pipe 22 to rotate are rotatably connected to the fixed frame 21, the rotation axis of the material receiving pipe 22 is vertical, the material receiving pipe 22 includes a straight pipe section and an inclined pipe section, the straight pipe section is located directly above the feed port of the small mixer 16 and is rotatably connected to the fixed frame 21, and one end of the inclined pipe section is connected to the upper end of the straight pipe section, and the other end is inclined upward, and a plurality of material receiving hoppers 24 are connected to the inclined pipe section at intervals, and the material receiving hoppers 24 are trumpet-shaped.

[0055] When the receiving pipe 22 is driven by the servo motor 23 to rotate, each receiving hopper 24 moves and passes directly below the discharge port of each weighing hopper 14. When the receiving hopper 24 is located directly below the weighing hopper 14, the discharge pipe 5 discharges the raw materials into the weighing hopper 14 for weighing. The weighed raw materials are discharged and fall into the receiving hopper 24. The raw materials are guided by the receiving hopper 24 and input into the receiving pipe 22, and then transported through the receiving pipe 22 to fall into the small mixer 16 for mixing.

[0056] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed. However, as long as it is within the scope of the claims of the present application, it shall be protected by the patent law.
