[0002] In the production process of slope protection bricks, accurate weighing and feeding of raw materials is a key step in ensuring the quality of slope protection bricks.

[0003] Currently, many manufacturers rely on manual weighing and feeding during the material feeding process. This method is not only labor-intensive and inefficient, but also prone to inconsistent quality due to the instability of manual operation. Although some manufacturers have adopted automated feeding equipment, these devices suffer from complex structures, high maintenance costs, and low weighing accuracy, failing to meet the demand for efficient and precise feeding in the production of slope protection bricks. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: providing an automatic weighing and feeding mechanism for slope protection bricks, including a storage bin, a feeding device, a weighing platform, a weighing sensor and a control system; The lower surface of the storage silo is provided with a discharge pipe, and the discharge pipe is equipped with an electromagnetic flow valve.

The control system is installed inside the controller.

[0005] Through the above technical solutions, the electromagnetic flow valve achieves precise control of the discharge flow rate, avoiding raw material overflow or blockage. The initial raw material outflow speed can be controlled by the opening and closing of the electromagnetic flow valve. The combination of screw conveyor and variable frequency motor can adjust the conveying speed according to needs to adapt to different production rhythms. The weighing sensor monitors the weight data in real time and feeds it back to the controller to achieve closed-loop control, improving weighing accuracy. The modular design of the storage silo, conveyor, and weighing platform facilitates integrated installation and use, and is easy to disassemble, maintain, and replace after damage.

[0006] The present invention is further configured such that a raw material inlet pipe is provided on the upper surface of the storage bin, a stirring motor is fixedly connected to the upper surface of the storage bin, and a stirring device is fixedly connected to the output end of the stirring motor.

When the storage bin is connected to the screw conveyor body, the annular baffle can prevent the screw conveyor body from being misaligned, which would lead to misalignment between the discharge pipe and the feed pipe.

[0013] The present invention is further configured such that the side surface of the discharge pipe contacts the annular stop block, and the upper end of the feed pipe contacts the discharge pipe.

The stirring motor 3, electromagnetic flow valve 6, screw conveyor body 9, frequency converter motor and weighing sensor 20 are all electrically connected to the control system. This is known to those skilled in the art.

[0023] By setting up a storage bin 1, a feeding device, a weighing platform, and a control system, the automatic weighing and feeding of raw materials for slope protection brick production is realized, replacing the traditional manual operation method, greatly reducing labor intensity and improving production efficiency. The screw conveyor body 9 is adopted, and the feeding speed of the screw conveyor body 9 can be adjusted by the control system to accurately control the feeding speed and realize quantitative feeding, ensuring the accuracy and consistency of each feeding, and effectively improving the quality of slope protection bricks. The weighing platform is equipped with a weighing sensor 20 and a tray 19, which can accurately weigh the raw material in real time and transmit the data to the control system, realizing real-time monitoring and feedback of weighing data.

[0024] The lower surface of the storage bin 1 is provided with a discharge pipe 5, and the discharge pipe 5 is provided with an electromagnetic flow valve 6. By controlling the opening of the electromagnetic flow valve 6, the initial raw material feeding speed is controlled. The feeding device includes a screw conveyor body 9 and a variable frequency motor. The variable frequency motor is fixedly connected to one end of the screw conveyor body 9, and the drive shaft of the screw conveyor body 9 is fixedly connected to the output end of the variable frequency motor.

[0025] The side surface of the discharge pipe 5 is symmetrically fixedly connected with a first mounting plate 51, the other end of the screw conveyor body 9 is fixedly connected with a discharge pipe 17, the screw conveyor body 9 is provided with a feed pipe 14, the side surface of the feed pipe 14 is fixedly connected with an annular stop block 15, the side surface of the annular stop block 15 is symmetrically fixedly connected with a second mounting plate 16, and the first mounting plate 51 and the second mounting plate 16 are fixedly connected by bolts.

[0026] The second mounting plate 16 of the annular stop 15 is bolted to the first mounting plate 51 to ensure that the discharge pipe 5 and the feed pipe 14 are connected to prevent material leakage. When the storage bin 1 is connected to the screw conveyor body 9, the annular stop 15 can prevent the screw conveyor body 9 from being misaligned, which would cause the discharge pipe 5 and the feed pipe 14 to be misaligned.

[0027] The side surface of the discharge pipe 5 contacts the annular stop block 15, the upper end of the feed pipe 14 contacts the discharge pipe 5, the side surface of the support column 7 is fixedly connected to the connecting block 8, the side surface of the connecting block 8 is provided with a T-slot 81, the side surface of the screw conveyor body 9 is fixedly connected to the T-block 12, the side surface of the T-block 12 is movably connected to the T-slot 81, one end of the T-block 12 is fixedly connected to the limiting plate 13, the T-block 12, the T-slot 81 and the limiting plate 13 cooperate to position the installation of the screw conveyor body 9, the side surface of the limiting plate 13 contacts the connecting block 8, the side surface of the screw conveyor body 9 is symmetrically provided with a crossbeam 10, the lower surface of the crossbeam 10 is provided with a universal wheel 11, the screw conveyor body 9 can move when the universal wheel 11 is in place, and the universal wheel 11 is provided with a self-locking device.

A support column 7 is fixedly connected to the lower surface of the storage bin 1, and a controller 21 is fixedly connected to the side surface of the support column 7.

[0029] The working principle of this utility model is as follows: In actual use, the raw materials for producing slope protection bricks are first put into the storage bin 1 through the raw material inlet pipe 2. The stirring motor 3 is started to make the stirring device 4 rotate, thereby stirring the raw materials to avoid uneven mixing. By adjusting the opening of the electromagnetic flow valve 6 of the discharge pipe 5 of the storage bin 1, a suitable initial discharge flow rate is set according to the production requirements. Then, the operator inputs the required raw material weight setting value into the control system of the controller 21, and starts the screw conveyor body 9 through the control system. The raw materials flowing out of the storage bin 1 enter the screw conveyor body 9, and the screw conveyor body 9 transports the raw materials in the storage bin 1 to the tray 19 of the weighing platform 18.

[0030] During the feeding process, the weighing sensor 20 detects the weight of the raw material on the tray 19 in real time and transmits the data to the control system. When the weighing data is close to the set value, the control system reduces the feeding speed of the screw conveyor body 9. When the weighing sensor 20 detects that the weight of the raw material has reached the set value, the control system immediately controls the screw conveyor body 9 to stop feeding, thus completing one weighing and feeding process.
