A concrete batching machine for concrete production comprises:

[0032] Rack 1, weighing hopper structure 3, material conveying structure 4, protection assembly 5 and filtering assembly 6, the inside left and right sides of rack 1 are fixedly connected with storage hoppers 2, weighing hopper structure 3 is located inside rack 1 below two storage hoppers 2, material conveying structure 4 is installed inside rack 1 below weighing hopper structure 3;

[0033] Filtering assembly 6 comprises rotating shaft 16, rotating shaft 16 is rotatably connected with the side wall surface of two storage hoppers 2, the top of rotating shaft 16 is fixedly connected with rotating baffle 15, the side wall surface of rotating baffle 15 is fixedly connected with filter screen 14, filter screen 14 is located inside storage hopper 2, the inner wall of storage hopper 2 below filter screen 14 is fixedly connected with limiting strip 19, the end of rotating shaft 16 is fixedly connected with large pulley 17, the side wall surface of one side storage hopper 2 is fixedly connected with control motor, the output end of control motor is fixedly connected with small pulley 18, and small pulley 18 and large pulley 17 are connected with a belt;

[0034] The protective component 5 includes a double-ended screw 7, which is rotatably connected to two storage hoppers 2. Movable parts 11 are threadedly connected to both sides of the surface of the double-ended screw 7. Protective cover plates 9 are fixedly connected to the surface of the movable parts 11. The protective cover plates 9 are located on the upper side of the storage hoppers 2. A drive motor 10 is provided on one side of the double-ended screw 7. The output end of the drive motor 10 is fixedly connected to one end of the double-ended screw 7.

[0035] like Figures 1-4 As shown, a positioning rod 8 is fixedly connected between the two storage hoppers 2 located on the upper side of the double-headed screw 7. The movable part 11 is slidably connected to the positioning rod 8. Side plates are fixedly connected to both ends of the positioning rod 8. The drive motor 10 is fixedly connected to one side plate.

[0036] Currently, many concrete batching machines are installed directly in outdoor open-air sites, where workers use excavators to dump various materials into different storage hoppers 2. However, the top of the hopper lacks protection and is directly exposed to the external environment. In rainy weather, water accumulates inside the hopper, and the materials get wet, which can easily hinder the normal discharge of materials from the subsequent storage hopper 2. In this device, when faced with rainy weather, the user can start the drive motor 10 to rotate the double-headed screw 7, so that the two moving parts 11 can move the protective cover 9 in a relatively close direction, thereby covering the top of the two sets of storage hoppers 2 and preventing external rainwater from wetting the materials inside. The structural design is reasonable.

[0037] like Figures 1-4 As shown, a rotating component 1 is rotatably connected to the outer wall surface of both storage hoppers 2. A first arc-shaped door 12 is fixedly connected to the bottom of the rotating component 1. The first arc-shaped door 12 matches the bottom of the storage hopper 2. A first telescopic cylinder 13 is hinged between the first arc-shaped door 12 and the side wall of the storage hopper 2.

[0038] When it is necessary to pour the material in the storage hopper 2 into the weighing hopper 20 below it, the first telescopic cylinder 13 is activated to move the first arc-shaped door 12 to one side.

[0039] like Figures 1-4 As shown, the weighing hopper structure 3 includes a weighing hopper 20. The weighing hopper 20 is located inside the frame 1, and the left and right side walls of the weighing hopper 20 are symmetrically fixed with first fixing ropes. The top of the first fixing rope is fixedly connected with a pressure sensor 28, and the top of the pressure sensor 28 is fixedly connected to the frame 1 through a second fixing rope.

[0040] The frame 1 suspends the pressure sensor 28 and the weighing hopper 20 by the first fixed rope. When the material in the storage hopper 2 enters the weighing hopper 20, the pressure sensor 28 will sense the change in value, thereby monitoring in real time whether the amount of added material meets the requirements.

[0041] likeFigures 1-4 As shown, the left and right side walls of the weighing hopper 20 are fixedly connected with limiting members 21, the limiting members 21 are slidably connected with limiting columns 22 inside, and the limiting columns 22 are vertically arranged and fixedly connected with the rack 1.

[0042] The limiting columns 22 and the limiting members 21 can limit the weighing hopper 20, and the pressure sensor 28 can monitor the weight of the materials in the weighing hopper 20.

[0043] As shown in the figure, Figures 1-4 The side wall surface of the weighing hopper 20 is rotatably connected with a rotating member two, the bottom of the rotating member two is fixedly connected with a second arc-shaped door 26, the second arc-shaped door 26 is matched with the bottom of the weighing hopper 20, and the second arc-shaped door 26 is hingedly connected with a second telescopic cylinder 27 between one side wall of the weighing hopper 20.

[0044] When the materials in the weighing hopper 20 are added, the second telescopic cylinder 27 is started to move the second arc-shaped door 26 to one side, so that the materials in the inside can smoothly fall into the lower material conveying structure 4.

[0045] As shown in the figure, Figures 1-4 The material conveying structure 4 comprises a fixed frame 24, the fixed frame 24 is fixedly connected with the surface of the rack 1, both ends of the fixed frame 24 are rotatably connected with rotating rollers 25, a conveying belt 23 is connected between the two rotating rollers 25, the rotating rollers 25 are provided with kinetic energy by an external motor, and the conveying belt 23 is located below the second arc-shaped door 26.

[0046] The conveying belt 23 is used to connect the area where the next step of the concrete production is located, so that the completed concrete materials can be smoothly transferred, and the design is reasonable.

[0048] First step: Now many concrete batching machines are directly installed in outdoor open sites, and workers use excavators to pour various materials into different storage hoppers 2, but the top of the material bin lacks protection and is directly exposed to the external environment. When it rains, water accumulates in the material bin, and the materials are wet, which can easily hinder the normal discharge of the later storage hopper 2. When the device is in a rainy environment, the user can start the driving motor 10 to drive the double-headed screw rod 7 to rotate, so that the two movable parts 11 can move the protective cover plate 9 towards the relatively close direction, thereby covering the top of the two groups of storage hoppers 2, avoiding the external rain from wetting the materials inside, and the structure design is reasonable.

[0049] The second step: at present, many concrete batching opportunities install filter screen 14 in storage hopper 2, so as to avoid that larger impurities enter the inside, but various impurities on the structure filter screen 14 cannot be cleaned quickly, and usually need manual operation, which is more troublesome, and in the device, when the impurities on the filter screen 14 in the storage hopper 2 are more, the control motor on one side is started to drive the small pulley 18 to rotate, and the kinetic energy is transmitted to the rotating shaft 16 by the cooperation of the belt and the large pulley 17, and the rotating shaft 16 is forced to rotate to drive the two groups of filter screens 14 to be turned outward, so that the impurities on the surface are poured to the outside, and the structure design can realize effective cleaning of the filter screen 14, and manual operation is not needed, which is more convenient and fast.

[0050] It should be noted that the device structure and the drawings of the utility model mainly describe the principle of the utility model, and the setting of the power mechanism, the power supply system and the control system of the device is not completely described in the technical principle of the design, and under the premise that the above-mentioned principle of the utility model is understood by the person skilled in the art, the specific of the power mechanism, the power supply system and the control system can be clearly known, and the control mode of the application file is automatically controlled by the controller, and the control circuit of the controller can be realized by simple programming of the person skilled in the art;
