Technical Field

[0001] This utility model relates to the field of commercial concrete mixing technology, and in particular to a raw material weighing and feeding device for commercial concrete mixing plants. Background Technology

[0002] Commercial concrete, also known as concrete, is a general term for engineering composite materials in which aggregates are bound together by cementing materials. The term "concrete" usually refers to cement concrete, also known as ordinary concrete, which is made by mixing cement as a cementing material, sand and gravel as aggregates, and water (which may contain admixtures and additives) in a certain proportion. It is widely used in civil engineering.

[0003] Currently, when feeding materials into a commercial concrete batching plant, it is usually necessary to accurately weigh the raw materials before feeding them in order to produce commercial concrete of better quality. However, the traditional weighing method usually involves weighing the raw materials directly on a balance scale, and the weighed commercial concrete is generally fed in manually. This weighing method is generally time-consuming and labor-intensive, which not only affects the production efficiency of commercial concrete, but also has certain limitations in use and needs to be improved.

[0004] Therefore, this application proposes a raw material weighing and feeding device for commercial concrete mixing plants to solve the problems in the background art. Utility Model Content

[0005] The purpose of this utility model is to provide a raw material weighing and feeding device for a commercial concrete mixing plant, which can not only automatically weigh the raw materials, but also automatically feed the weighed raw materials into the commercial concrete mixing tank.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a raw material weighing and feeding device for a commercial concrete mixing plant, including a support frame and a control panel;

A horizontal plate is fixedly connected to the support frame, and a weighing scale is fixedly mounted on the horizontal plate. Each of the multiple weighing bins corresponds to the weighing scale. Two guide plates are fixedly mounted on the horizontal plate, located on both sides of the weighing scale. A control panel is fixedly mounted on the support frame, and the weighing scale is connected to the control panel. A motor is fixedly mounted on the support frame, and the output end of the motor is connected to one end of one of the two drive rollers. Through the coordinated design of the support frame, drive rollers, conveyor belt, weighing bins, weighing scale, motor, feed hopper, and control panel, not only can the effect of automatic weighing of raw materials be achieved, but also the automatic feeding of the weighed raw materials into the commercial concrete mixing tank can be realized.

[0009] A further feature of this invention is that a solenoid valve is installed on the feeding pipe, and the solenoid valve is connected to the control panel for regulating the opening and closing of the feeding pipe.

[0010] A further feature of this invention is that the height of both guide plates is adapted to the weighing scale to guide the multiple weighing barrels, facilitating the placement of the weighing barrels on the weighing scale. Multiple universal balls are movably installed on one side of the two guide plates to reduce friction.

[0011] A further feature of this invention is that each of the two drive rollers has a groove, and each of the two grooves corresponds to a plurality of weighing barrels, so that the plurality of weighing barrels can rotate with the conveyor belt.

[0012] A further feature of this invention is that a commercial concrete mixing tank is provided on one side of the support, the commercial concrete mixing tank is connected to the control panel and is used to mix and stir the raw materials, and a feed hopper is sealed to the top of the commercial concrete mixing tank. The feed hopper corresponds to multiple weighing barrels and is used to transport the raw materials into the commercial concrete mixing tank.

[0013] A further feature of this invention is that two limiting rings are fixedly fitted on each of the multiple weighing barrels and are respectively located on both sides of the conveyor belt, for limiting the multiple weighing barrels and preventing the multiple weighing barrels from detaching from the conveyor belt.

[0014] A further feature of this invention is that the conveyor belt has multiple mounting slots, and multiple weighing barrels are movably installed in the multiple mounting slots respectively. The multiple limiting rings are all larger than the multiple mounting slots to prevent the conveyor belt from affecting the weighing of the weighing barrels by the weighing scale.

Through the coordinated design of the support 1, drive rollers 2, conveyor belt 3, weighing barrels 4, weighing scale 6, motor 8, feed hopper 12 and control panel 10, not only can the effect of automatic weighing of raw materials be achieved, but also the automatic feeding of the weighed raw materials into the commercial concrete mixing tank 11 can be achieved.

[0026] See attached document Figure 1 A support plate 13 is fixedly installed on the bracket 1, and a feeding pipe is fixedly installed on the support plate 13. The feeding pipe corresponds to multiple weighing barrels 4 and is used to convey raw materials into the weighing barrels 4. A solenoid valve is installed on the feeding pipe and is connected to the control panel 10 to regulate the opening and closing of the feeding pipe.

[0027] See attached document Figure 1-3 The height of the two guide plates 7 is adapted to the weighing scale 6, and is used to guide the multiple weighing barrels 4, so that the weighing barrels 4 can be placed on the weighing scale 6. Multiple universal balls 9 are installed on one side of the two guide plates 7 to reduce friction.

[0028] See attached document Figure 4 Both drive rollers 2 have grooves, and each groove corresponds to a plurality of weighing barrels 4, so that the plurality of weighing barrels 4 can rotate with the conveyor belt 3.

[0029] See attached document Figure 2 A concrete mixing tank 11 is provided on one side of the support 1. A stirring rod is rotatably installed inside the concrete mixing tank 11. A drive motor is fixedly installed on the top of the concrete mixing tank 11. The output end of the drive motor is connected to one end of the stirring rod. The drive motor is connected to the control module 10. A discharge pipe is provided on one side of the concrete mixing tank 11. A valve is provided on the discharge pipe. The concrete mixing tank 11 is connected to the control panel 10 for mixing raw materials. A feed hopper 12 is sealed to the top of the concrete mixing tank 11. The feed hopper 12 corresponds to multiple weighing buckets 4 for conveying raw materials into the concrete mixing tank 11.

[0030] See attached document Figure 4Each of the multiple weighing barrels 4 is fixedly fitted with two limiting rings 14 located on both sides of the conveyor belt 3, which are used to limit the multiple weighing barrels 4 and prevent them from detaching from the conveyor belt 3. The conveyor belt 3 has multiple mounting slots, and the multiple weighing barrels 4 are movably installed in the multiple mounting slots. The multiple limiting rings 14 are larger than the multiple mounting slots to prevent the conveyor belt 3 from affecting the weighing of the weighing barrels 4 by the weighing scale 6. The multiple weighing barrels 4 are arranged equally on the conveyor belt 3.

[0031] Working principle: When in use, first connect the power supply and drive the solenoid valve, motor 8 and concrete mixing tank 11 through the preset program in the control panel 10;

[0032] First, by controlling the opening and closing of the solenoid valve on the feeding pipe, the raw materials can be fed into the corresponding weighing barrel 4. At the same time, the weighing scale 6 can weigh the raw materials in the weighing barrel 4 and transmit the data to the control panel 10 in real time. The control panel 10 analyzes and judges the data through a preset program. When the value reaches the preset value, the control panel 10 sends a command to the solenoid valve and closes the feeding pipe, thereby achieving the effect of weighing the raw materials.

[0033] Subsequently, through the intermittent drive of the motor 8 and the coordinated transmission between the two transmission rollers 2 and the conveyor belt 3, the conveyor belt 3 drives multiple weighing barrels 4 to rotate intermittently. During this process, the weighing barrels 4 will interact with one of the two guide plates 7, thereby enabling the weighing barrels 4 to be automatically placed on the weighing scale 6.

[0034] Subsequently, driven by the motor 8, the conveyor belt 3 can transport the weighed weighing bucket 4 to the feeding hopper 12, and the weighing bucket 4 can rotate a certain angle around the transmission roller 2, thereby pouring the raw material in the weighing bucket 4 into the feeding hopper 12, thus achieving the effect of automatic feeding.

[0035] The technological advancements of this invention compared to existing technologies are as follows: through the cooperation of various components, not only can the raw materials be automatically weighed, but the weighed raw materials can also be automatically put into the commercial concrete mixing tank 11, which greatly improves convenience and processing efficiency. Moreover, the structure is simple and the practicality is higher.
