[0045] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0046] Embodiment 1

[0047] See also Figure 1-6 A foam concrete processing automatic batching and mixing equipment, including a main body component 1, the main body component 1 includes: a mixing box 11, the top of which is symmetrically provided with a feed port 12; a discharge port 13, which is connected to the right side wall of the mixing box 11; a water pipe 14, which is connected to the left side wall of the mixing box 11; a bracket 15, which is arranged on the top of the mixing box 11; a batching and mixing component 2 is arranged on the mixing box 11 and the bracket 15, and the batching and mixing component 2 includes: a hopper 21, which is arranged on both sides of the bracket 15, and the bottom of the hopper 21 has through holes on both sides; an electric push rod 22, one end of which is rotatably connected to the front side wall of the hopper 21 through a rack; a rotating shaft 211, which is symmetrically arranged at the front and rear of the hopper 21 Side wall; baffle plate 23, rotatably connected to the outside of the rotating shaft 1 211; rotating shaft 231, obliquely symmetrically arranged on the outer side wall of the baffle plate 23, the output shaft of the electric push rod 22 is rotatably connected to the rotating shaft 2 231 at the top; connecting rod 24, both ends of which are rotatably connected to the rotating shaft 2 231; gravity sensor 25, arranged on the inner bottom surface of the hopper 21, the gravity sensor 25 is electrically connected to the electric push rod 22; rotating rod 1 26, rotatably connected to the inside of the mixing box 11, the left end of the rotating rod 1 26 penetrates and extends to the left side wall of the mixing box 11; stirring blade 261, arranged on the outside of the rotating rod 1 26; motor 27, the output shaft of which is fixedly connected to the left end of the rotating rod 1 26. The inner bottom surface of the mixing box 11 is an inclined surface. The outer side of the rotating rod 1 26 is symmetrically provided with scrapers 262, and the scrapers 262 and the stirring blades 261 are in contact with the inner bottom surface of the mixing box 11.

[0048] Before use, the staff first pours the raw materials into the two hoppers 21 respectively, and then uses the batching and stirring component 2 to proportion and stir the raw materials: the raw materials fall into the bottom of the hopper 21, and the gravity sensor 25 that has been set in advance detects the weight of the raw materials. When the weight of the raw materials reaches the set value, the gravity sensor 25 sends a switch signal to the electric push rod 22, and the electric push rod 22 gradually shrinks from the extended state. The second shaft 231 at the output end of the electric push rod 22 drives the top of the baffle plate 23 to rotate along the first shaft 211 until the top of the baffle plate 23 gradually approaches the electric push rod 22. The baffle plates 23 are connected by connecting rods 24, and when the baffle plates 23 on one side connected to the output shaft of the electric push rod 22 rotate and tilt, the connecting rod 24 pushes the baffle plates 23 on the other side to rotate along the rotating shaft 1 211. At this time, the two baffle plates 23 are away from both sides of the hopper 21 at the same time, and the raw materials in the hopper 21 fall into the feed port 12 below through the through holes on both sides of the hopper 21 until the gravity sensor 25 is not subjected to the weight of the raw materials, and the gravity sensor 25 controls the electric push rod 22 to extend until the baffle plates 23 on both sides are rotated back to the bottom of the hopper 21, and the baffle plates 23 block the through holes on both sides of the hopper 21. The staff can set different critical values ​​of the gravity sensors 25 in the two hoppers 21 to control the batching of different raw materials. After the raw materials fall into the mixing box 11 through the feed port 12, the water source at the water pipe 14 is turned on, and the motor 27 is started. The motor 27 drives the rotating rod 26 to rotate, and the stirring blades 261 outside the rotating rod 26 fully stir and mix the raw materials and water. The mixed concrete is discharged from the mixing box 11 through the discharge port 13. The inclined surface of the bottom surface of the mixing box 11 speeds up the discharge of concrete from the discharge port 13 to prevent the concrete from accumulating at the bottom of the mixing box 11, which is inconvenient to clean. When the rotating rod 26 drives the stirring blades 261 to stir, the scraper 262 outside the rotating rod 26 scrapes the inner wall of the mixing box 11 to prevent the raw materials or concrete from adhering to the inner wall of the mixing box 11, which is inconvenient for the staff to clean later.

[0049] Embodiment 2

[0050] On the basis of the first embodiment, a function of crushing the foam concrete raw materials is added.

[0051] See also Figure 1-6The mixing box 11 is provided with a crushing assembly 3, which includes: a rotating rod 2 31, which is symmetrically and rotationally connected to the left side wall of the mixing box 11, and the rotating rod 2 31 penetrates and extends into the mixing box 11; a pulley group 1 32, on which two pulleys are respectively fixedly connected to the rotating rod 2 31 on the right and the rotating rod 1 26; a pulley group 2 33, on which two pulleys are respectively fixedly connected to the rotating rod 2 31 on the left and right; a crushing roller 34, which is fixedly connected to the right side of the rotating rod 2 31, and the crushing roller 34 is rotationally connected to the inner wall of the mixing box 11. The crushing assembly 3 also includes a scraper 35 provided on the inner wall of the mixing box 11, and the tooth shape of the scraper 35 is meshed with the tooth shape of the crushing roller 34. The scraper 35 is symmetrically provided at two locations, and the scraper 35 is designed to be inclined.

[0052] Since raw materials such as cement and gypsum in foam concrete are prone to agglomeration, it is not convenient to improve the quality of concrete if the agglomerated cement and gypsum are directly mixed without treatment, so the crushing assembly 3 is used to crush the raw materials: the raw materials enter the mixing box 11 through the feed port 12 and fall onto the crushing roller 34. Since the rotating rod 1 26 is connected to the rotating rod 2 31 on the right side through the pulley group 1 32, after the motor 27 is started, the rotating rod 1 26 and the rotating rod 2 31 rotate synchronously. The rotating rods 2 31 at the two locations are connected through the pulley group 2 33, so that the two rotating rods 2 31 drive the two crushing rollers 34 to rotate simultaneously, and the crushing roller 34 crushes the raw materials. The crushed raw materials continue to be stirred by the stirring blade 261. The scraper 35 is meshed with the crushing roller 34, so that the scraper 35 scrapes off the raw materials adhering to the crushing roller 34 when the crushing roller 34 rotates, so as to prevent the raw materials from adhering to the crushing roller 34 and affecting the normal use of the crushing roller 34. The scraper 35 is tilted to prevent the raw materials from being accumulated on the scraper 35 .
