Description

Technical Field

[0001] The utility model relates to the technical field of concrete batching, in particular to a concrete batching device. Background Technique

[0002] Concrete is an important building material widely used in civil engineering, abbreviated as "concrete", which refers to the general term of an engineering composite material in which an aggregate (such as sand and stone) is cemented into a whole by a cementitious material (such as cement). Ordinary concrete is mainly prepared by mixing cement, sand, stone and water in a certain proportion and stirring. In the process of preparing concrete, it is necessary to ensure that the amount of each material is appropriate. Therefore, a concrete batching device is needed. Using the batching device to quantify each material can replace the traditional manual measurement and ensure the accuracy and efficiency of the concrete ratio.

[0003] In the existing concrete batching device, multiple hoppers that can discharge materials quantitatively are used for batching. After batching, the sand, gravel and cement fall onto the conveying structure for conveying. However, when the existing concrete batching device is in use, a single conveying structure is used for the conveying work of materials. Due to the existence of stones, if a screw conveyor is used, the conveying effect cannot be guaranteed and jamming is likely to occur. If a conveyor belt is used for the conveying of all materials, dust will appear during the cement feeding process, which will affect the cleanliness of the batching environment. Moreover, in the existing concrete batching device, after the cement is put into the hopper, when the cement falls through the hopper, the cement will also generate dust due to the vibration of the device. The dust diffuses from above the hopper, which will still cause the batching environment to deteriorate and affect the health of the staff. Summary of the Utility Model

[0004] The utility model provides a concrete batching device, which solves the problem that dust generated during the cement feeding process in the related technology affects the batching environment.

Specific embodiments

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Such as Figures 1-6As shown in the figure, a concrete batching device includes a bracket 1, on which a first hopper 2 is provided. A conveying pipe 3 is installed on the bracket 1, and a second hopper 4 and a third hopper 5 are installed on the conveying pipe 3. A shielding structure 6 is provided on the third hopper 5. A conveying rack 7 is provided on the bracket 1, and one end of the conveying rack 7 is located below the first hopper 2. A spiral blade is provided inside the conveying pipe 3, and a motor connected to the spiral blade is provided at the end of the conveying pipe 3. A discharge port 8 is provided at the end of the conveying pipe 3. Flow regulating components 9 are provided on the first hopper 2, the second hopper 4, and the third hopper 5. The flow regulating component 9 includes a regulating plate, a support seat, and a cylinder. The cylinder is installed on the support seat, and the telescopic shaft of the cylinder is connected to the regulating plate. The three regulating plates are respectively connected to the first hopper 2, the second hopper 4, and the third hopper 5. The stones discharged from the first hopper 2 are transported through the conveying rack 7, and the sand and cement discharged from the second hopper 4 and the third hopper 5 are transported through the conveying pipe 3. The conveying pipe 3 can effectively prevent dust, avoiding the dust generated by the cement falling material from diffusing into the environment.

[0023] When using the concrete batching device, the device is stably placed through the bracket 1. Stones are put into the first hopper 2, sand and cement are respectively put into the second hopper 4 and the third hopper 5. The flow control of the discharging is carried out through the flow regulating component 9, so as to achieve the effect of quantitative proportioning. During the adjustment, the cylinder on the support seat is started, and the cylinder drives the regulating plate to move, thereby controlling the flow of the corresponding hopper. The stones discharged from the first hopper 2 fall onto the conveying rack 7 and are transported through the conveying rack 7, and finally discharged from the end of the conveying rack 7. The sand and cement discharged from the second hopper 4 and the third hopper 5 enter the conveying pipe 3. The motor at the end of the conveying pipe 3 is started to drive the spiral blade to rotate, thereby driving the sand and cement to move, and finally discharged from the discharge port 8. During this process, the conveying pipe 3 plays a role in blocking dust, avoiding the dust generated by the transportation of the cement falling material from diffusing into the environment. The shielding structure 6 on the third hopper 5 also plays a role in blocking dust, avoiding the dust generated by the vibration during the operation of the device from diffusing above the third hopper 5 due to the cement, further ensuring the cleanliness of the environment.

[0024] Through the above implementation solutions, the shielding structure 6 includes a shielding plate 601, a servo motor 602, a gear 603, a rack 604, and a cleaning assembly 608. The shielding plate 601 is installed on the third hopper 5. The gear 603 is installed on the servo motor 602, and the servo motor 602 is fixed on the bracket 1. The rack 604 is arranged on the shielding plate 601. The cleaning assembly 608 is installed on the shielding plate 601. The shielding structure 6 further includes a stop block 605, a first limiting assembly 606, a second limiting assembly 607, and a threaded hole 609. The gear 603 is meshed and connected with the rack 604. The stop block 605 is fixed on the bracket 1. The first limiting assembly 606 is installed on the shielding plate 601. The second limiting assembly 607 is fixed on the third hopper 5. The threaded hole 609 is opened on the shielding plate 601. The first limiting assembly 606 includes a rubber block 6061, a counterbore 6062, and a countersunk head bolt 6063. The counterbore 6062 is opened on the rubber block 6061. The countersunk head bolt 6063 is arranged in the counterbore 6062, and the end of the countersunk head bolt 6063 is connected to the shielding plate 601. The second limiting assembly 607 includes a fixing plate 6071, a groove 6072, a rubber pad 6073, and a fixing screw 6074. The groove 6072 is opened on the fixing plate 6071, and the fixing plate 6071 is fixed on the third hopper 5 through the fixing screw 6074. The rubber pad 6073 is arranged in the groove 6072. The cleaning assembly 608 includes a mounting block 6081, a brush 6082, and a connecting screw 6083. The brush 6082 is fixed on the mounting block 6081. The connecting screw 6083 passes through the mounting block 6081, and the end of the connecting screw 6083 is connected to the threaded hole 609. By adopting the shielding structure 6, when cement is put into the third hopper 5, it is in a yielding state. After the cement is put in, the structures in the shielding structure 6 operate, and the shielding plate 601 moves to cover the third hopper 5, which can play an effect of shielding dust during the feeding process, further avoiding the dispersion of cement dust into the environment and ensuring the environmental cleanliness. The first limiting assembly 606 and the second limiting assembly 607 play a role of limiting and buffering when the shielding plate 601 moves. The cleaning assembly 608 cleans the inner wall of the upper end of the third hopper 5, which can ensure the smooth movement of the shielding plate 601.

[0025] When installing the shielding structure 6, the shielding plate 601 is slidably installed at the upper end of the third hopper 5. Cleaning components 608 are arranged at both ends of the shielding plate 601. During the setting, the fixing of the mounting block 6081 is completed by the cooperation of the connecting screw 6083 and the threaded hole 609. The brush 6082 contacts the inner wall of the third hopper 5. Subsequently, the first limiting component 606 and the second limiting component 607 are installed respectively. A countersunk bolt 6063 is arranged in the countersunk hole 6062, and the rubber block 6061 is fixed to the shielding plate 601 through the countersunk bolt 6063. A rubber pad 6073 is arranged in the groove 6072, and the fixing plate 6071 is installed on the outer wall of the third hopper 5 by using the fixing screw 6074. Subsequently, the rack 604 and the servo motor 602 are installed. A gear 603 is arranged on the servo motor 602 to ensure that the gear 603 is meshed and connected with the rack 604, thereby completing the installation work of the entire shielding structure 6. When in use, in the initial state, the shielding plate 601 covers the third hopper 5. When it is necessary to put cement, the servo motor 602 is started. The servo motor 602 drives the gear 603 to rotate and applies a force to the rack 604, so that the shielding plate 601 moves on the third hopper 5 to make way. During this process, the first limiting component 606 contacts the stop block 605 for buffering and limiting. After the space above the third hopper 5 is vacated, the cement is put in. Then the servo motor 602 is started again to drive the shielding plate 601 to move. The shielding plate 601 moves in the reverse direction to cover the third hopper 5. During this process, after the shielding plate 601 contacts the rubber pad 6073, the rubber pad 6073 plays a buffering role, and at the same time the fixing plate 6071 blocks and limits to ensure that the shielding plate 601 accurately covers the third hopper 5. After the shielding plate 601 covers, at this time the cement is discharged through the third hopper 5. The whole device runs and generates vibration. Under the action of vibration, some dust is generated in the cement in the third hopper 5. The shielding plate 601 can effectively block the dust and ensure the environmental cleanliness. During the movement of the shielding plate 601, the brush 6082 in the cleaning component 608 contacts the inner wall of the third hopper 5 to play a cleaning role, avoiding the adhesion of cement dust on the inner wall of the third hopper 5 and affecting the sliding of the shielding plate 601. The structure is simple and the use effect is excellent.
