Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of shotcreting machine, concretely relates to an intelligent weighing and feeding system of shotcreting machine. BACKGROUND

[0002] In mine construction, shotcreting operation not only concerns the safety and stability of engineering support, but also directly affects the construction efficiency and cost control. The traditional shotcreting operation mode, i.e. manual batching, mixing, feeding and handheld spray gun operation, has many drawbacks. First, manual operation has high labor intensity and low operation efficiency, which is difficult to meet the demand of modern mine construction for rapidness and efficiency. Second, since manual operation cannot guarantee the uniformity of each batching and mixing, it leads to unstable shotcreting quality and high rebound rate, which not only wastes materials, but also increases the workload of subsequent cleaning and repair. In addition, long-term operation in a dusty environment makes workers prone to pneumoconiosis and other occupational diseases, which poses a serious threat to the health of the construction team.

[0003] In order to solve these problems, the development trend of mine mechanization, automation and intelligence is increasingly obvious. In recent years, some shotcreting machines with high automation have appeared on the market, which have improved the construction efficiency and reduced the labor intensity of workers to some extent. However, these shotcreting machines still have some deficiencies in slurry conveying and weighing.

[0004] In terms of slurry conveying, although some shotcreting machines have realized automatic feeding, they lack flexible adjustment mechanism and cannot adjust the conveying speed of slurry according to actual needs. This leads to unstable flow of slurry during shotcreting, affecting the uniformity and quality of shotcreting. In addition, the feeding system of some shotcreting machines is complex in structure, high in maintenance cost and prone to failure, which affects the normal construction.

[0005] In terms of weighing, although some shotcreting machines are equipped with weighing systems, the weighing precision and stability need to be improved. At the same time, the communication between these weighing systems and the control center is not smooth, which cannot realize real-time data transmission and automatic adjustment of water supply volume and other functions. This means that manual intervention is still needed to ensure the accuracy of the ratio during construction, which not only reduces the work efficiency, but also increases the risk of human error.

[0006] In summary, the existing problems in slurry conveying and weighing of shotcreting machines need to be solved. Therefore, the development of an intelligent weighing and feeding system that can automatically weigh, feed and work with the automatic water supply system of the shotcreting machine is of great significance for improving the efficiency and quality of mine shotcreting operation, reducing construction cost and protecting workers' health. The utility model is proposed based on this demand, aiming to solve the existing problems of shotcreting machines through technological innovation and promote the development of mine construction towards more intelligent and automated direction.

[0034] I. System Composition and Installation

[0035] 1. The weighing hopper 1 is fixed to the weighing hopper support frame 3 by a high-precision weighing sensor 2 to ensure accurate measurement of the weight of the slurry.

[0036] 2. The bottom valve 5 of the weighing hopper is fixed to the bottom of the weighing hopper 1, and its opening and closing are controlled by the weighing hopper valve control motor 4 to achieve precise discharge of slurry.

[0037] 3. The feeding machine consists of a bottom mounting plate 8, an upper cover plate 10, a top mounting plate 11, and a U-shaped outer shell 18, forming a complete feeding machine housing. The feed inlet 7 is connected to the upper cover plate 10 of the feeding machine and is fixed by the feeding machine support frame 6.

[0038] 4. Both the weighing hopper support frame 3 and the feeding machine support frame 6 are fixed on the moving base 9. The bottom of the moving base 9 is equipped with casters to facilitate the movement and positioning of the entire system.

[0039] II. Working Principle and Operating Procedure

[0040] 1. Preparation stage:

[0041] The slurry is poured into the weighing hopper 1, and the weighing sensor 2 measures the weight of the slurry in real time and transmits the data to the control center.

[0042] Based on construction requirements and slurry characteristics, the mixing parameters and procedures are preset in the control center.

[0043] 2. Material feeding stage:

[0044] Start the screw shaft motor 13 of the feeder, and drive the screw shaft 12 of the feeder to rotate through the universal joint 14 of the feeder.

[0045] Driven by the screw shaft, the slurry enters the feed port 7 from the weighing hopper 1 through the bottom valve 5 of the weighing hopper, and then is conveyed upward along the screw shaft 12 of the feeder to the discharge port 16.

[0046] The conveying speed of the slurry can be controlled by adjusting the rotation speed of the screw shaft motor 13 of the feeder to meet the needs of different construction conditions.

[0047] 3. Weighing and water supply coordination stage:

[0048] During the slurry conveying process, the weighing sensor 2 continuously monitors the weight change of the slurry in the weighing hopper 1 and transmits the data to the control center.

[0049] When the slurry weight reaches the preset value, the control center automatically closes valve 5 at the bottom of the weighing hopper to stop further slurry delivery.

[0050] Meanwhile, the control center automatically adjusts the water supply of the automatic water supply system of the shotcrete machine according to the preset mixing parameters and the received slurry weight information to ensure accurate mixing ratio of slurry and water.

[0051] 4. End Phase:

[0052] After the slurry delivery is complete, turn off the screw shaft motor 13 of the feeder and disconnect the power. Clean the weighing hopper 1 and the inside of the feeder of any residual slurry to keep the system clean and hygienic.

[0053] As needed, the entire system can be moved to the next work location for the next round of operations.

[0054] III. Precautions and Maintenance

[0055] 1. During use, the accuracy and sensitivity of the weighing sensor 2 should be checked regularly to ensure the accuracy of its measurement data.

[0056] 2. Regularly lubricate and maintain the screw shaft 12 and universal joint 14 of the feeder to reduce wear and failure rate.
