[0023] The following is combined with Figure 1 -Attached Figure 4 This application is described in further detail.

[0024] The present application embodiment discloses a hopper hydraulic support automatic weighing system.

[0025] Reference Figure 1A traction rod 4 is hinged at the bottom of the frame 1, and the frame 1 is towed by the traction rod 4, so that the frame 1 can be moved to a specified position.

[0026] Reference Figure 2 A pressure bearing plate 12 is installed on each outrigger oil cylinder 11, and a pressure detection module 121 is connected to the pressure bearing plate 12. The pressure detection module 121 includes a pressure sensor. The pressure detection modules 121 on each pressure bearing plate 12 are electrically connected to a control system, and the control system is electrically connected to each outrigger oil cylinder 11. When in use, the frame 1 is lifted to a certain height as a whole by each outrigger oil cylinder 11, so that each universal wheel 31 is not subjected to force, and the supporting force of each outrigger oil cylinder 11 is obtained through the pressure detection module 121 on each pressure bearing plate 12, and data analysis and processing are performed through the control system to automatically adjust the supporting force of each outrigger oil cylinder 11 to ensure that the supporting force of each outrigger oil cylinder 11 is relatively stable, thereby improving the accuracy of weighing.

[0027] Reference Figure 1 and Figure 3 A discharge port 21 is provided at the bottom of the funnel body 2, and the discharge port 21 is connected to a discharge bag 22, and the discharge bag 22 is connected to a discharge cylinder 23, and the discharge cylinder 23 is fixedly arranged on the frame 1; a sealing mechanism for closing the discharge port 21 is provided on the funnel body 2, and the sealing mechanism includes a gate 24 and a servo cylinder 25. A mounting port 26 connected to the discharge port 21 is provided on the side wall of the funnel body 2, and the gate 24 is slidably arranged in the mounting port 26. The servo cylinder 25 is fixedly arranged on the frame 1, and the piston rod of the servo cylinder 25 is fixedly connected to the gate 24, and the control system is electrically connected to the servo cylinder 25.

[0028] The weight information is detected by the pressure detection modules 121 on each pressure bearing plate 12, and the control system performs data analysis and processing to monitor the total weight of the entire frame 1, the funnel body 2 and the material in real time. When the loading vehicle completes the material loading, the control system controls the servo cylinder 25 to move, and the gate 24 closes the discharge port 21 of the funnel body 2. At this time, the material loading amount of the loading vehicle can be obtained according to the change of the weight information fed back by each pressure detection module 121, which solves the problem of the traditional weighing method being complicated and having many conversion links, and greatly improves the weighing efficiency of the material.

[0029] Reference Figure 3 A plurality of transmission wheels 27 are rotatably arranged in the installation opening 26 and at the bottom of the gate 24. The transmission wheels 27 are rollingly connected to the gate 24. The gate 24 is supported by the transmission wheels 27 to reduce the friction resistance of the gate 24 during the opening and closing process, thereby improving the operating efficiency and service life of the sealing mechanism.

[0030] Reference Figure 1A material level meter 28 is installed in the funnel body 2. The material level meter 28 is electrically connected to the control system. The control system is electrically connected to an alarm device 13. The alarm device 13 includes an audible and visual alarm, a light alarm or a broadcasting speaker. When the material level meter 28 detects that the material in the funnel body 2 is lower than a certain amount, it feeds back data to the control system, and then controls the alarm device 13 to sound an alarm through the control system, so that the staff can replenish the material in time.

[0031] Reference Figure 1 and Figure 4 , a plurality of balancing wheels 14 are rotatably arranged on the top of the frame 1, and these balancing wheels 14 are grouped in pairs, and the two balancing wheels 14 in the same group are arranged on both sides of the funnel body 2, and a lifting rope 15 is wound around the two balancing wheels 14 in the same group, and both ends of the lifting rope 15 are fixedly connected to the funnel body 2, and are used to lift the funnel body 2 on the frame 1, and a tube 16 is fixedly arranged between the two balancing wheels 14 in the same group, and the lifting rope 15 is passed through the tube 16; during the material loading process, if the material in the funnel body 2 is offset, the center of gravity of the funnel body 2 will also change accordingly. At this time, through the mutual cooperation of the balancing wheels 14 and the lifting rope 15, the position of the funnel body 2 will be automatically fine-tuned according to the change of the center of gravity of the funnel body 2. This design ensures that the supporting force of each leg cylinder 11 on the frame 1 is always stable, so that the weighing data of the material shows a stable change trend during the outflow process, and the weighing accuracy is further improved.

[0032] Reference Figure 4 A plurality of connecting rod barrels 17 are fixedly arranged on the frame 1, and each connecting rod barrel 17 is distributed along the circumference of the funnel body 2, and the length direction of the connecting rod barrel 17 is vertical, and a damping block 18 is slidably arranged in each connecting rod barrel 17 along the vertical direction, and a damping spring 19 is also arranged in each connecting rod barrel 17, and the top of the damping spring 19 is fixedly arranged in the connecting rod barrel 17, and the bottom end of the damping spring 19 is fixedly connected to the damping block 18, and a safety rope 181 is fixedly connected to each damping block, and the safety rope 181 is fixedly connected to the funnel body 2, and under normal circumstances, the safety rope 181 is in a relaxed state. If the lifting rope 15 breaks, the safety rope 181 is stressed, and the funnel body 2 is hoisted to improve the construction safety; and when the safety rope 181 is stressed, the damping spring 19 first provides a certain tensioning force to the funnel body 2, thereby avoiding the safety rope 181 from being subjected to excessive impact force when it is just stressed, resulting in the safety rope 181 breaking, and further improving the construction safety.

[0033] The implementation principle of the hopper hydraulic support automatic weighing system of the embodiment of the present application is as follows: when in use, the frame 1 is lifted to a certain height as a whole by the outrigger oil cylinders 11, so that the universal wheels 31 are not subjected to force, and the material weight information is obtained by the pressure detection modules 121 on the pressure bearing plates 12, and the data is analyzed and processed by the control system to monitor the total weight of the entire frame 1, the hopper body 2 and the material in real time. When the loading vehicle completes the material loading, the servo cylinder 25 is controlled by the control system to move, and the discharge port 21 of the hopper body 2 is closed by the gate 24. According to the changes in weight information fed back by each pressure detection module 121, the material loading capacity of the loader can be obtained, which solves the problem of complex traditional weighing methods and many conversion links, and greatly improves the weighing efficiency of materials; and according to the weight information fed back by the pressure detection modules 121 on each pressure bearing plate 12, the supporting force of each hydraulic cylinder is automatically adjusted to ensure that the supporting force of each leg cylinder 11 is relatively stable, thereby improving the accuracy of weighing; further, the automatic weighing system of the present application can also accurately control the opening and closing of the sealing mechanism according to the discharge requirements, thereby improving practicality.
