DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0020] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 A structural diagram of a preferred embodiment of a concrete mixing device provided by the utility model Figure 1 ; Figure 2 A structural diagram of a preferred embodiment of a concrete mixing device provided by the utility model Figure 2 ; Figure 3 It is a schematic diagram of the structure of the first feeding hopper and the first transmission device in the utility model; Figure 4 It is a schematic diagram of the cross-sectional structure of the stirring device in the utility model; Figure 5 It is a structural schematic diagram of the batching device in the utility model.

[0021] A concrete mixing device comprises: a mixing box 1, support legs 2 and a motor 3, wherein the motor 3 penetrates the mixing box 1 and is fixedly connected with a mixing device 4, a first support seat 7 and a second support seat 10 are arranged on both sides of the mixing box 1, a first feed hopper 8 and a first transmission device 9 are fixedly connected to the first support seat 7, a second feed hopper 11 and a third feed hopper 12 are fixedly connected to the second support seat 10, a second transmission device 13 and a batching device 14 are arranged below the second support seat 10, and a feed port is opened at a location corresponding to the first transmission device 9 and the second transmission device 13 on the mixing box 1.

[0022] Stone is added to the first hopper 8, and silt and cement are added to the second hopper 11 and the third hopper 12 respectively. The discharging speed of the silt and cement is controlled by the batching device 14 to achieve the purpose of proportioning and mixing the raw materials.

[0023] The stirring device 4 includes a transmission shaft 41, which passes through the stirring box 1 and is fixedly connected to the motor 3. A stirring blade 42 is fixedly connected to the transmission shaft 41. An auger blade 43 is fixedly provided at one end of the transmission shaft 41 away from the stirring blade 42. A discharge port 5 is opened at a position corresponding to the stirring box 1 and the auger blade 43, and a discharge guide plate 6 is fixedly connected below the discharge port 5.

[0024] After all the raw materials are added into the mixing box 1, the motor 3 is started to drive the mixing blades 42 to rotate and mix the raw materials. After the mixing is completed, the concrete is driven by the auger blades 43 through the discharge port 5 and falls on the discharge guide plate 6, and then enters the next process.

[0025] The first transmission device 9 includes a fixed rod 91, which is fixedly connected to the lower surface of the first support seat 7. A mounting plate 92 is fixedly connected to the fixed rod 91. A first conveyor belt 93 and a material dividing rod 94 are arranged between the mounting plates 92. The material dividing rod 94 is located above the first conveyor belt 93. A first material guide plate 95 is arranged below the first conveyor belt 93.

[0026] The stones in the first feeding hopper 8 fall down and land on the first conveyor belt 93, and then enter the mixing box 1 through the first guide plate 95 and the corresponding feeding port on the mixing box 1; when the stones pass through the dividing rod 94, the accumulated stones are dispersed to prevent the problem of uneven mixing caused by the accumulation of raw materials.

[0027] The second transmission device 13 includes a base 131 . A second conveyor belt 132 is disposed on the upper portion of the base 131 . A second material guide plate 133 is disposed below the second conveyor belt 132 .

[0028] The silt and cement in the second hopper 11 and the third hopper 12 fall onto the second conveyor belt 132 and then move onto the second guide plate 133. Since the second guide plate 133 forms an inclination angle with the horizontal plane, the silt and cement fall into the stirring device 1 through the corresponding feed port.

[0029] The batching device 14 includes a fixed plate 141 , connecting rods 142 are fixedly provided on both sides of the fixed plate 141 , the ends of the connecting rods 142 are fixedly connected to electric telescopic rods 143 , and the ends of the electric telescopic rods 143 are provided with bosses 144 .

[0030] After adding sufficient amounts of silt and cement to the second and third hoppers 11, 12, the electric telescopic rod 143 is started. The bottom diameter of the boss 144 is equal to the outlet diameter at the bottom of the second and third hoppers 11, 12. After the electric telescopic rod 143 is started, the boss 144 is driven to move downward so that it no longer blocks the outlet. The discharge speed of the hopper is controlled according to the height of the boss, thereby achieving the purpose of proportioning the raw materials entering the mixing box 1.

[0031] The boss 144 is provided with bulk material protrusions 145 arranged in a circular array.

[0032] When the raw materials in the second hopper 11 and the third hopper 12 fall, they can disperse the accumulated raw materials when passing through the dispersing protrusions 145 provided on the boss 144, thereby avoiding the problem of uneven mixing of the raw materials due to poor dispersion uniformity of the raw materials.

[0033] The working principle of a concrete mixing device provided by the utility model is as follows:

[0034] Stones are added to the first feed hopper 8, and enter the mixing box 1 through the first conveyor belt 93, the first guide plate 95 and the corresponding feed port on the mixing box 1; when the stones pass through the dividing rod 94, the accumulated stones are dispersed to prevent the problem of uneven mixing caused by the accumulation of raw materials; after adding sufficient mud and cement to the second feed hopper 11 and the third feed hopper 12, the electric telescopic rod 143 is started, and the bottom diameter of the boss 144 is equal to the outlet diameter at the bottom of the second feed hopper 11 and the third feed hopper 12. After the electric telescopic rod 143 is started, the boss 144 is driven to move downward so that it no longer blocks the outlet. According to the height of the boss, the speed of the feed hopper discharging is controlled to achieve the purpose of proportioning the raw materials entering the mixing box 1; after all the raw materials are added to the mixing box 1, the motor 3 is started to drive the mixing blade 42 to rotate to mix and stir the raw materials. After the mixing is completed, the concrete is driven by the auger blade 43 through the discharge port 5 and falls on the discharge guide plate 6, and then enters the next process.

[0035] Compared with the related art, the concrete mixing device provided by the utility model has the following beneficial effects:

[0036] Stone is added to the first hopper, and the discharge amount of mud in the second hopper and cement in the third hopper can be controlled according to the set batching device, so as to achieve the purpose of proportioning and mixing the raw materials. There is no need to proportion the concrete raw materials through other devices and then stir them, which simplifies the process and reduces costs.

[0037] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
