Description

Technical Field

[0001] The utility model relates to the technical field of concrete, in particular to an automatic feeding and stirring mechanism for a concrete mixing station. Background Art

[0002] Concrete, abbreviated as concrete, is a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. The term concrete usually refers to cement as the cementitious material, sand and stone as aggregates; and water in a certain proportion, mixed and obtained by cement concrete, also known as ordinary concrete, which is widely used in civil engineering.

[0003] The existing automatic feeding and mixing mechanisms of concrete mixing plants all rely on a rotary auger for feeding. However, there may be large particles of sand and gravel in the concrete raw materials, or the workers may discharge too much material at one time. These situations will cause blockage in the feeding pipe and affect the rotation of the rotary auger, resulting in the inability to feed the concrete raw materials into the mixing barrel for mixing.

The internal sliding connection of the dustproof box is provided with a gear ring for driving the sealing plate to move back and forth, and the outer wall of the rotating rod is fixedly connected with a semicircular gear for engaging the gear ring.

[0009] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0010] In this application, the staff first turns on the motor, and then discharges the concrete raw materials into the feed hopper.

[0019] like Figure 1-3As shown, an automatic feeding and mixing mechanism of a concrete mixing station includes a mixing barrel 1, a stirring rod 2 for stirring concrete raw materials is installed inside the mixing barrel 1, a feeding pipe 3 for replenishing concrete raw materials into the mixing barrel 1 is connected to the top of the mixing barrel 1, a rotary auger 4 for pushing the concrete raw materials to move is rotatably connected inside the feeding pipe 3, a feeding hopper 5 for replenishing concrete raw materials into the feeding pipe 3 is installed on the rotary auger 4, a crushing component for crushing large particles of sand and gravel is installed in the feeding hopper 5, and a controlled discharge component is installed on the feeding hopper 5 to prevent the feeding pipe 3 from being blocked due to excessive discharge of material at one time.

[0020] Example 2:

[0021] The technical solution is basically the same as that of embodiment 1, except that Figure 2 As shown, the crushing assembly includes a crushing hammer 6 for crushing large particles of sand and gravel. The number of crushing hammers 6 is set to multiple and the multiple crushing hammers 6 are arranged in a ring and equidistantly in sequence. The inner wall of the feed hopper 5 is fixedly connected with a guide plate 7 for discharging sand and gravel to the crushing hammer 6. The guide plate 7 is arranged in an inclined shape and the high end of the guide plate 7 is connected to the top of the feed hopper 5. The number of the guide plates 7 is set to two and the two guide plates 7 are arranged in a mirror-symmetrical manner. A rotating rod 9 for driving the crushing hammer 6 to rotate is rotatably connected in the feed hopper 5. A filter plate 8 for filtering large particles of sand and gravel is fixedly installed on the inner wall of the feed hopper 5. Filter holes are opened on both sides of the top of the filter plate 8 and the middle part is a straight plate without holes. A motor 10 for driving the rotating rod 9 to rotate is installed at the bottom of the rotating rod 9. A dust box 11 is fixedly installed at the bottom of the filter plate 8 to prevent sand and gravel dust from contaminating the motor 10.
