A guide plate 42 is slidably provided on the frame 1 through a lifting cylinder 40, and a feed port corresponding to the batching bin is provided on the guide plate 42.

[0028] Each of the batching bins is slidably provided with a adding bin 45, which is connected from top to bottom. The adding bin 45 is made of transparent material, and the front side of the adding bin 45 is also marked with scales. The two adding bins 45 are slidably connected to the batching plate 41 through a telescopic rod 46. An elastic member is provided on the telescopic rod 46. The elastic member resets and combines with the gravity of the adding bin 45 to drive the adding bin 45 to descend.

[0029] like Figure 5-6 As shown, a water adding assembly 5 is provided on the frame 1, and the water adding assembly 5 includes a water tank 52, which is symmetrically installed on the frame 1, and the water tank 52 is connected to the mixing barrel 3 through a water adding pipe 50. A box cover 53 is installed on the top of the water tank 52, and a liquid guide tube 51 is passed through the box cover 53. A plurality of small holes are opened on the upper end of the liquid guide tube 51, and the liquid guide tube 51 slides through the bottom of the water tank 52 and is connected to the water adding pipe 50. The front side wall of the water tank 52 is transparent and marked with scales. The two water tanks 52 are connected to a water inlet pipe 54 on the opposite side. An indicator plate 55 is sleeved on the liquid guide tube 51, and the indicator plate 55 is below the small holes and inside the water tank 52.

[0030] like Figure 7-8 As shown, a dispersing assembly 6 is connected to the bottom of the guide plate 42, and the dispersing assembly 6 includes a dispersing barrel 60, which is connected to the bottom of the guide plate 42 through the discharge port, and the dispersing barrel 60 passes through the top and bottom, and a stirring blade 61 is rotatably connected inside the dispersing barrel 60.

[0031] A transmission gear 62 is rotatably connected to one side of the outer wall of the beating barrel 60, and the transmission gear 62 is coaxial with the stirring blade 61. A connecting slider 64 is slidably connected to the front side of the guide plate 42, and a transmission rack 63 is connected to the bottom of the connecting slider 64, and the transmission rack 63 is meshed with the transmission gear 62. A connecting slide rod 65 is slidably connected to the front side of the guide plate 42 through a guide block 66. The right end of the connecting slide rod 65 is fixedly connected to the connecting slider 64, and a tension spring 67 is connected between the guide block 66 and the connecting slider 64. A protrusion 68 is slidably inserted on the top of the connecting slider 64, and a reset spring 69 is connected between the protrusion 68 and the connecting slider 64. A slope is provided on the top of the protrusion 68, and the protrusion 68 is in contact with the limit slider 47.

[0032] like Fig. 9 As shown, the bottom of the beating barrel 60 is connected to a dry mixing box 7, and the discharge port at the bottom of the dry mixing box 7 corresponds to the mixing barrel 3 in the vertical direction.

[0033] It also includes a material receiving assembly 8, which includes a material receiving box 81. The material receiving box 81 is connected to both sides of the dry mixing box 7 through a connecting frame 82. The material receiving box 81 is located below the support portion 401. A scraper 80 is symmetrically slidably provided on the guide plate 42, and the scraper 80 is pushed by the batching bin and / or the adding bin 45.

[0034] When mixing, the two required materials are respectively placed in the two feed hoppers 2, and the electric push rod 44 is used to control the sliding of the batching plate 41 to align one of the batching bins with one of the feed hoppers 2, and the material in the batching bin is observed through the scale while unloading. When the need is met, the batching plate 41 is controlled to slide to align the other batching bin with the other feed hopper 2. During the sliding process, the prepared material in the first batching bin will fall into the scattering barrel 60 from the discharge port of the guide plate 42, and at the same time, the limit slider 47 will contact and push the protrusion 68 to move to the right, thereby driving the rack to move to the right and driving the stirring blade 61 to rotate through the transmission gear 62. The stirring blade 61 scatters the falling material to prevent condensation. When the tension spring 67 is stretched to the limit, the limit slider 47 presses down and passes over the protrusion 68, and the tension spring 67 is reset; after the other batching bin is prepared, the electric push rod 44 moves in the opposite direction, contacts and pushes the protrusion 68 to move to the left, and the tension spring 67 is compressed. Similarly, the stirring blade 61 scatters the other falling material.

[0035] Before mixing, fill the water tank 52 with water. When all the materials pass through the dry mixing box 7 and fall into the mixing barrel 3, the mixing barrel 3 slides downward under the action of gravity, and the water adding pipe 50, the liquid guiding pipe 51 and the indicator plate 55 descend at the same time. The multiple small holes on the upper end of the liquid guiding pipe 51 enter the water tank 52. At this time, water flows into the mixing barrel 3 through the small holes. The amount of water added can be known through the scales on the indicator plate 55 and the water tank 52, and the water amount can be adjusted according to actual needs.

[0036] During batching, if the demand for a certain material exceeds the scale range of the batching bin, the guide plate 42 is controlled to descend by the lifting cylinder 40, and the batching plate 41 is blocked by the support part 401 and will not fall. The adding bin 45 slides downward under the action of its own gravity and the elastic part on the telescopic rod 46, thereby increasing the amount that can be batched for a single material.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
