DETAILED DESCRIPTION

[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0034] Reference Figure 1 and Figure 3, a concrete mixer with automatic weighing and mix ratio calculation provided by the utility model is now described. The concrete mixer with automatic weighing and mix ratio calculation comprises: a mixing tank 1, a weighing mechanism 2, a feeding mechanism 3 and a mixing mechanism 5. A feed port 11 and a discharge port 12 are provided on the mixing tank 1, wherein the feed port 11 is provided in the upper half of the side surface of one end of the mixing tank 1, and the discharge port 12 is provided in the lower half of the side surface of one end of the mixing tank 1. The weighing mechanism 2 is provided at the feed port 11, and the feeding structure is provided below the weighing mechanism 2 for pushing the weighing mechanism 2 so as to deliver the raw materials on the weighing mechanism 2 through the feed port 11 into the interior of the mixing tank 1. The mixing mechanism 5 is provided inside the mixing tank 1 for mixing various concrete raw materials in the mixing tank 1.

[0035] Reference Figure 2 The weighing mechanism 2 includes a base 21 hinged at one end on the side of the mixing tank 1, a weighing pump 22 installed on the base 21, and a weighing plate 23 installed on the weighing pump 22. The hinge axis of the base 21 is located below the feed port 11. When weighing the concrete raw materials, the base 21, the weighing pump 22 and the weighing plate 23 are in a horizontal state. When weighing the concrete raw materials, the raw materials are placed on the weighing plate 23, and the weighing pump 22 weighs the weight of the raw materials. After the raw materials are weighed, the feeding mechanism 3 pushes the base 21 to rotate, so that the raw materials on the weighing plate 23 are fed into the mixing tank 1 through the feed port 11.

[0036] Reference Figure 2 The feeding mechanism 3 includes a fixed plate 31 welded on the side of the mixing tank 1 and a telescopic component 32 mounted on the fixed plate 31. The telescopic component 32 can be a cylinder or a hydraulic cylinder. In this embodiment, a cylinder is used as an example for description. One end of the cylinder is hinged on the fixed plate 31 through a mounting seat, and the telescopic tube of the cylinder is hinged on the base 21 through a mounting seat 54.

[0037] A modified implementation of the above-mentioned characteristic telescopic component 32 is that the telescopic component 32 includes a driving motor and a telescopic sleeve. The driving motor is hinged on the fixed plate 31 through a mounting seat, the top of the telescopic sleeve is hinged on the bottom of the base 21, the telescopic sleeve is sleeved on the power output shaft of the driving motor, and the telescopic sleeve is threadedly matched with the power output shaft of the driving motor. When the driving motor is working, the power output shaft rotates, thereby driving the telescopic sleeve to extend or retract. The telescopic sleeve drives the weighing mechanism 2 to rotate during the movement.

[0038] After the concrete raw materials are weighed, the telescopic component 32 works and extends its length, pushing the base 21 to rotate, and the base 21 drives the weighing pump 22 and the weighing plate 23, so that the concrete raw materials on the weighing plate 23 are sent into the mixing tank 1 from the feed port 11.

[0039] Reference Figure 3The stirring mechanism 5 includes a stirring shaft 51 installed inside the stirring tank 1, a stirring rod 52 welded to the stirring shaft 51, an auger 55 welded to the stirring rod 52, a mounting base 54 arranged outside the stirring tank 1, and a motor 53 installed on the mounting base 54.

[0040] Mounting holes are provided on the sides of both ends of the stirring tank 1, and the stirring shaft 51 is inserted into the mounting holes, and one end thereof passes through the mounting holes. A bearing is provided between the stirring shaft 51 and the inner wall of the mounting hole. The power output shaft of the motor 53 is connected to the end of the stirring shaft 51 extending out of the stirring tank 1 through a coupling. The stirring rod 52 is arranged vertically with the stirring shaft 51, and the auger 55 is located at the end of the stirring rod 52 close to the inner wall of the stirring tank 1.

[0041] A switch door 6 is provided at the discharge port 12 of the mixing tank 1. Two horizontal slide rails 7 are installed on the outer side of the mixing tank 1, and the two slide rails 7 are respectively located at the upper and lower sides of the discharge port 12. Two sliders are installed on the switch door 6, and the two sliders are respectively matched with the two slide rails 7. The switch door 6 can slide in the horizontal direction under the cooperation of the sliders and the slide rails 7. During the process of preparing concrete, the switch door 6 is slid to close the feed port 11. After the concrete preparation and mixing are completed, the switch door 6 is slid to open the discharge port 12.

[0042] After the various raw materials of concrete are prepared, the motor 53 is started, the motor 53 drives the stirring shaft 51 to rotate, and the stirring rod 52 and the auger 55 stir the concrete. Since the auger 55 has the ability to transport materials, the auger 55 can make the concrete concentrate on one side of the mixing tank 1, which is not conducive to the uniform mixing of various materials of the concrete. Therefore, when stirring the concrete, the motor 53 is regularly controlled to reverse so that the concrete cannot be concentrated on one side of the mixing tank 1.

[0043] After the concrete mixing is completed, the switch door 6 is opened, the motor 53 is started, and the electricity drives the auger 55 to rotate in one direction through the mixing shaft 51, so that the auger 55 drives the concrete in the mixing tank 1 to flow out from the discharge port 12 when rotating.

[0044] The concrete mixer with automatic weighing and mix ratio calculation provided in this embodiment also includes a control module, which is in communication connection with a weighing pump 22. When the staff prepares the concrete, the weighing pump 22 can output the name of the raw material, and the weighing pump 22 sends the name and weight of the raw material to the control module after weighing the raw material. The control module receives and records the name and weight of the raw material called by the weighing pump 22, and calculates the mix ratio of the concrete according to the name and weight of the raw material called by the weighing pump 22.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
