[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1-3 A mixing and casting device for precast concrete slabs includes a mixing chamber 1, a mixer 2 mounted on the mixing chamber 1, a precast slab mold 4 mounted below the mixing chamber 1 and placed on a conveyor belt 5, and a material distribution mechanism 3 mounted on the top of the mixing chamber 1 for introducing multiple sets of raw materials into the mixing chamber 1. The material distribution mechanism 3 includes a hopper 31, a partition 32 mounted on the hopper 31, which divides the hopper 31 into multiple hoppers 33 for temporarily storing raw materials, and a discharge pipe 34 for discharging raw materials from the hoppers 33 at the bottom of the hoppers 31 below the hoppers 33. A baffle is inserted into the discharge pipe 34 to block the discharge pipe 34. The outer end of the baffle 35 is connected to a telescopic rod 36 for pushing the baffle 35 to move. The telescopic rod 36 is mounted on the bracket 37. The hopper 31 has a concave cylindrical structure and an umbrella-shaped structure at the bottom. The partition 32 is located inside the hopper 31. The number of discharge pipes 34 is equal to the number of silos 33. The bottom of the discharge pipes 34 is connected to the top of the mixing chamber 1 and is used to connect the silos 33 and the mixing chamber 1. The baffle 35 moves laterally and inserts into the discharge pipe 34. The telescopic rod 36 has a telescopic length greater than half the length of the baffle 35. The telescopic rod 36 can be an electric or hydraulic telescopic rod. The bottom end of the bracket 37 is fixedly connected to the outer wall of the mixing chamber 1.
[0022] The raw materials are sorted and placed into each group of hoppers 33. Then, the telescopic rod 36 is driven to pull the baffle 35 to move within the discharge pipe 34. As the baffle 35 moves outward, the distance between it and the discharge pipe 34 increases, and the raw materials in the corresponding hopper 33 enter the mixing chamber 1 through the discharge pipe 34. The mixer 2 is started to mix the raw materials in the mixing chamber 1, so that a single hopper 31 can temporarily store multiple groups of raw materials, and the order in which multiple groups of raw materials enter the mixing chamber 1 can be selected according to needs.
[0023] The bottom of the mixing chamber 1 is provided with a feeding mechanism 6, which is used to introduce the mixture in the mixing chamber 1 into the precast slab mold 4. The feeding mechanism 6 includes a feeding pipe 61 located at the bottom of the mixing chamber 1. A feeding pipe 62 is provided on the side wall of the feeding pipe 61 to connect the feeding pipe 61. The feeding pipe 61 has two sets symmetrically distributed at the bottom of the mixing chamber 1. Both the feeding pipe 61 and the feeding pipe 62 are provided with valve bodies. The feeding pipe 62 has a Y-shaped structure.
[0024] After the mixer 2 finishes mixing, the first discharge pipe 61 is opened, and the discharge pipe 61 introduces the mixture in the mixing chamber 1 into the precast slab mold 4. At the same time, the second discharge pipe 62 can be opened, or the first discharge pipe 61 can be closed and the second discharge pipe 62 can be opened alone, so that the mixture enters the precast slab mold 4 through the second discharge pipe 62. This allows material to be conveyed to multiple positions in the precast slab mold 4, improving the material conveying effect into the precast slab mold 4.
[0025] Working principle: This utility model classifies and places raw materials into each group of hoppers 33, then drives the telescopic rod 36 to pull the baffle 35 to move within the discharge pipe 34. As the baffle 35 moves outward, the distance between it and the discharge pipe 34 increases, allowing the raw materials in the corresponding hopper 33 to enter the mixing chamber 1 through the discharge pipe 34. The mixer 2 is then started to mix the raw materials in the mixing chamber 1, enabling a single hopper 31 to temporarily store multiple groups of raw materials. The order in which multiple groups of raw materials enter the mixing chamber 1 can be selected according to requirements. After the mixer 2 finishes mixing, the discharge pipe 1 61 is opened, allowing the mixture in the mixing chamber 1 to be fed into the precast slab mold 4. Simultaneously, the discharge pipe 2 62 can be opened, or the discharge pipe 1 61 can be closed while the discharge pipe 2 62 is opened alone, allowing the mixture to enter the precast slab mold 4 through the discharge pipe 2 62. This allows for material feeding to multiple locations within the precast slab mold 4, improving the material feeding efficiency.
[0026] The mixer 2, the precast slab mold 4, the conveyor belt 5, and the telescopic rod 36 are all existing technologies and will not be described in detail here.
[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
