[0030] Example 1

[0031] The weighing mechanism for the production of ready-mixed concrete is provided with a weighing structure, which can directly add the concrete ingredients into the weighing box 3 for weighing, making the operation faster. Specifically:

[0032] A feed hopper 2 is provided on the upper surface of the shell 1, and also includes a weighing box 3. The weighing box 3 is located inside the shell 1, and the weighing box 3 is connected to a weighing structure. The weighing structure can add ingredients into the weighing box 3 through the feed hopper 2 so that the weight sensor 9 weighs the ingredients. The weighing structure includes a motor 5. The motor 5 is installed on the upper surface of the weighing box 3. The upper surface of the weighing box 3 is provided with an opening, which corresponds to the lower end of the feed hopper 2. A tooth plate 6 is provided through the inner wall of the opening of the weighing box 3, and a tooth block is provided on the front surface of the tooth plate 6. The tooth block on the front surface of the tooth plate 6 is engaged with a gear 7. The coaxial ends of the gear 7 are connected to the motor 5. A slide groove is provided on the side surface of the inner wall of the weighing box 3, and the slide groove is slidably connected with a slider 10. A bottom plate 8 is installed between the two sliders 10. A weight sensor 9 is installed on the upper surface of the bottom plate 8. Two tooth plates 6 are symmetrically provided.

[0033] When the batching weighing mechanism for ready-mixed concrete production is used, Figure 1 As shown, first, the two motors 5 are turned on, so that the motor 5 drives the gear 7 to rotate. Since the gear 7 is engaged with the tooth block provided on the front surface of the tooth plate 6, the gear 7 rotates to move the tooth plate 6. At this time, the two tooth plates 6 move in opposite directions, so that the opening provided on the upper surface of the weighing box 3 is opened, and then the ingredients to be weighed are poured into the feed hopper 2 on the upper surface of the shell 1, and then the ingredients enter the interior of the weighing box 3 through the opening provided on the upper surface of the weighing box 3, and then the ingredients will be accumulated on the upper surface of the bottom plate 8. Since a weight sensor 9 is provided on the upper surface of the bottom plate 8, the poured ingredients can be weighed. At the same time, as shown in FIG. Figure 3 As shown, a window is provided on the front surface of the housing 1, which can be used to observe the weighing situation. When the weight reaches the requirement, the filling is stopped, and then the motor 5 is turned on, so that the motor 5 drives the gear 7 to rotate, and the tooth plate 6 moves to close the opening on the upper surface of the weighing box 3.

[0034] Example 2

[0035] The batching weighing mechanism for ready-mixed concrete production is provided with a rotating discharging structure, which can enable the weighing box 3 to quickly discharge the batching block through the rotating shaft 4, and then weigh the next batching, thereby improving the batching efficiency. Specifically:

[0036] The weighing box 3 is also connected to a rotary discharging structure, which enables the weighing box 3 to rotate through the rotating shaft 4 to turn the opening downward to cooperate with the bottom plate 8 to vibrate and discharge the ingredients. The rotary discharging structure includes a rotating shaft 4, which is fixedly mounted on the side surface of the weighing box 3, and the other end of the weighing box 3 is rotatably mounted on the inner wall side surface of the shell 1, one of the rotating shafts 4 is connected to a motor 2 12, and the motor 2 12 is mounted on the side surface of the shell 1, the lower surface of the slider 10 is installed with a spring 11, and the lower surface of the inner wall of the shell 1 is slidably mounted with a receiving frame 1 3. A handle 14 is provided on the front surface of the material receiving frame 13. The rotary discharging structure includes a rotating shaft 4, which is fixedly mounted on the side surface of the weighing box 3, and the other end of the weighing box 3 is rotatably mounted on the side surface of the inner wall of the shell 1. One of the rotating shafts 4 is connected to a second motor 12, and the second motor 12 is mounted on the side surface of the shell 1. A spring 11 is installed on the lower surface of the slider 10. The material receiving frame 13 is slidably mounted on the lower surface of the inner wall of the shell 1. The front surface of the material receiving frame 13 is provided with a handle 14, and the upper surface of the material receiving frame 13 is set to an open state;

[0037] After the weighing inside the weighing box 3 is completed, the motor 2 12 on the side surface of the shell 1 will be turned on, so that the motor 2 12 drives the shaft 4 to rotate, and then the shaft 4 will drive the weighing box 3 to rotate as a whole, until the upper surface of the weighing box 3 rotates to the bottom and corresponds to the upper surface opening of the material receiving frame 13, and then the motor 1 5 is turned on to make the tooth plate 6 move to open the opening, and the ingredients inside the weighing box 3 will be discharged into the material receiving frame 13. At the same time, the bottom plate 8 inside the weighing box 3 slides downward in the slide groove on the inner side surface of the weighing box 3 through the connected slider 10. Since the slider 10 is connected with a spring Spring 11, so the bottom plate 8 will generate a certain shock force, making the discharge of ingredients cleaner, and the inclined structure inner wall at the opening of the weighing box 3 can also make the ingredients discharged quickly. Further, after the ingredients are discharged, the motor 2 12 will rotate the rotating shaft 4, so that the weighing box 3 rotates back to the initial state, and then the next ingredient is weighed. Finally, when all the ingredients have completed the proportioning weighing and are discharged into the receiving frame 13, the receiving frame 13 is pulled out through the handle 14 on the front surface of the receiving frame 13, which is convenient for the lower concrete mixing work and improves the proportioning efficiency.

[0038] Working principle: When using the ingredient weighing mechanism for ready-mixed concrete production, the concrete ingredients can be quickly mixed through the weighing structure, and the ingredients can be quickly discharged for the next weighing through the rotating discharging structure, which improves work efficiency and increases overall practicality.
