Technical Field

A switch component is provided at the bottom of the concrete quantitative proportioning device body, and a conveying component is installed at the bottom of the switch component. The quantitative proportioning component includes a feed inlet, a scale, a bottom baffle, a baffle rotating shaft, a baffle connecting rod, a baffle sliding switch, and a connecting rod groove. A scale is provided on the side of the feed inlet, and the bottom of the feed inlet is tightly fitted with the bottom baffle.

[0046] Working Principle: When mixing concrete, the operator pours five pieces of raw material into the mixing tank 2 through the feed hopper. Then, the operator starts the equipment via the control panel, activating the reverse servo motor 10 and the forward servo motor 16. The reverse servo motor 10 drives the reverse drive wheel 8 to rotate, which in turn drives the reverse driven wheel 7 via the reverse belt 9. The reverse driven wheel 7 drives the reverse shaft 11 to rotate counterclockwise, which in turn drives multiple scrapers 12. The scrapers 12 mix the concrete raw materials and clean the inner wall of the mixing tank 2 to prevent the raw materials from adhering to the inner wall. The forward servo motor 16 drives the forward drive wheel 14 to rotate, which in turn drives the forward driven wheel 13 via the forward belt 15. The forward driven wheel 13 drives the forward shaft 17 to rotate clockwise, which in turn drives the mixing shell 18 to rotate. Simultaneously, the mixing shell 18 rotates... The stirring servo motor 22 installed inside the mixing tank 8 starts, driving the active bevel gear 19 to rotate. The rotation of the active bevel gear 19 drives the two adjacent driven bevel gears 25 to rotate, and the rotation of the two driven bevel gears 25 drives the same driven bevel gear 25 to rotate. The rotation of the three driven bevel gears 25 of the active bevel gear 19 drives the corresponding stirring shaft 20 to rotate, and the rotation of multiple stirring shafts 20 drives the corresponding stirring blades 21 to rotate, thus stirring the concrete inside the mixing tank 2. This helps to improve the mixing effect of the raw materials. At the same time, the rotation of the mixing shell 18 drives the linkage shaft 23 to rotate, and the linkage shaft 23 drives the notched metal block 24 to rotate. When the notched metal block 24 rotates, the notch created allows the concrete to fall, preventing too much concrete from falling at the same time and causing blockage of the discharge port. After mixing is completed, the operator activates the electric control valve 3 through the control panel, allowing the concrete to fall into the collection bin 4 through the discharge port, completing the mixing.

[0047] The technological advancements achieved by this invention compared to existing technologies are: it can prevent concrete raw materials from adhering to the inner wall of the mixing tank 2, thereby affecting the mixing effect and the accuracy of the proportioning, increasing the practicality of the equipment; at the same time, it can better stir the concrete at the bottom of the mixing tank 2, making it more uniformly mixed.
