Description

Technical Field

[0001] The present application relates to the technical field of the discharging supporting structure in the production and use of concrete, and in particular to a quantitative discharging structure of a concrete mixing plant. Background Art

[0002] Concrete is an indispensable building material in the existing production and construction fields. Generally, it is directly quantitatively mixed by a concrete mixing plant and then transported to the use site by a pump truck. However, in some small-scale and short-distance use scenarios, as well as in the case of some mobile mixing plants used around the construction site, different-volume transportation tools existing on the construction site, such as small cars and trucks, are used for temporary transfer. Due to the limitations of the use scenario, sometimes it is necessary to supply materials to multiple use locations, and the volume of concrete transported each time cannot be too large. Since the existing concrete mixing plant has low accuracy in controlling the discharge, mainly by opening the switch for a certain period of time to control the discharge, this makes the volume of concrete transported by the transportation device uneven. Especially in some use scenarios for making precast components, it will affect normal production. Therefore, it is necessary to improve the existing discharging structure of the concrete pump station and propose a quantitative discharging structure to solve these problems. Summary of the Invention

Detailed Embodiments

[0020] The following further describes the present application in detail with reference to the drawings.

[0021] In order to more clearly understand the technical solutions shown in the embodiments of the present application, first, the working principle of the quantitative discharge of the existing concrete mixing plant is introduced.

[0022] In the existing concrete metering discharge, the timed discharge method is mostly used. Although this method can roughly ensure that the discharged volume tends to be consistent, the accuracy is poor. When the silo is full and when the silo carries less concrete, the discharge speeds are different, and the deviation is large. There is also a pressure-type discharge method that uses weight as a control signal. However, components such as sensors in this structure are more likely to be damaged during actual use, and the manufacturing cost is higher. In actual production, it is still mainly manually controlled, which makes the metering discharge unable to meet the needs of some scenarios with higher accuracy requirements. Therefore, it is necessary to improve the existing metering discharge equipment to solve these problems.

[0023] Please refer to Figures 1 to 3 , which is a metering discharge structure of a concrete mixing plant disclosed in an embodiment of the present application, including: a connecting bottom plate 1, side rails 2, connecting blocks 3, electric push rods 4, a blanking frame 5, an adjusting plate 6, a connecting seat 7, an adjusting screw 8, a closing baffle 9, a guiding plate 10, and support legs 11. One end of the connecting bottom plate 1 is bent downward. The side rails 2 are respectively fixedly connected to both sides of the connecting bottom plate 1. The connecting blocks 3 are fixedly connected to the upper surface of the connecting bottom plate 1 on the side away from the bend. The connecting end of the electric push rod 4 is fixedly connected to the connecting block 3. The blanking frame 5 has a rectangular appearance, and the upper and lower ends of the blanking frame 5 are open. The blanking frame 5 is slidably connected to the upper surface of the connecting bottom plate 1, and both sides of the blanking frame 5 are slidably connected to the inner surfaces of the side rails 2. The telescopic end of the electric push rod 4 is fixedly connected to one end of the blanking frame 5. The adjusting plate 6 is fitted and connected inside the blanking frame 5, and the lower end of the adjusting plate 6 is on the same plane as the lower surface of the blanking frame 5. The connecting seat 7 is fixedly connected to the surface of the adjusting plate 6 on the side away from the electric push rod 4. One end of the adjusting screw 8 is rotatably connected to the connecting seat 7, and the other end of the adjusting screw 8 is threadedly connected to the middle position of the blanking frame 5. The closing baffle 9 is fixedly connected to the surface of the blanking frame 5 corresponding to the upper part of the electric push rod 4, and the upper surface of the closing baffle 9 is on the same plane as the upper surface of the blanking frame 5. The guiding plate 10 is fixedly connected to the surface of the bent position of the connecting bottom plate 1. The support legs 11 are fixedly connected to the lower surface of the connecting bottom plate 1 in a rectangular array.

[0024] Specifically, the provided connecting base plate 1 is used to provide a position for connection and support. The side bar 2 provided at its edge can block the blanking frame 5, enabling it to move along a straight line direction and maintaining the stability of the movement trajectory. The provided connecting block 3 can connect the electric push rod 4 to ensure the firmness of its support. Under the push of the electric push rod 4, the blanking frame 5 can move on the connecting base plate 1. When the lower end of the blanking frame 5 exceeds the downward bending part of the connecting base plate 1, the internally loaded concrete will flow out quickly along the bend. The provided adjusting plate 6 can change its position within the blanking frame 5 under the rotation of the adjusting screw 8, thereby changing the bearing space formed by the adjusting plate 6 and the end of the blanking frame 5, greatly increasing the volume range of materials that can be carried. In the actual use process, the size and height of the blanking frame 5 can be adapted according to the actual scenario to meet the material volume requirements of different application fields. The provided connecting seat 7 can support the adjusting plate 6, thereby dispersing the transmission and supporting force of the adjusting screw 8 and ensuring the strength of the adjusting plate 6. The upper end and both sides of the adjusting plate 6 are slidably connected to the upper end and the inner wall of the blanking frame 5 respectively, and at the same time, it can form a good blocking effect to prevent the concrete from leaking out from the side. The provided closing baffle 9 can, when discharging forward, close the end of the existing discharging pipeline to achieve a blocking effect, preventing the concrete from continuing to fall into the blanking frame 5 due to improper control, and after the discharging is completed, it can open the space above the blanking frame 5 relative to the discharging pipeline, enabling the remaining materials to fall into the blanking frame 5, realizing the continuous and quantitative discharging without interruption. The provided guiding plate 10 can guide the concrete reaching the downward bending position of the connecting base plate 1 to a certain position in the bearing and transferring container, improving the convenience of the use scenario. The provided support legs 11 can firmly support the connecting base plate 1 to a certain height to meet different use requirements.

[0025] Please refer to Figure 2 , as another specific implementation provided by the application, it further includes a strengthening seat 12.

The adjusting rod 13 is fixedly connected to the end of the adjusting screw 8, and the adjusting rod 13 is perpendicular to the axial direction of the adjusting screw 8.

[0028] Specifically, the setting of the adjusting rod 13 can improve the convenience of rotating the adjusting screw 8, meeting the requirements of the usage scenario. In actual use, a rotating handle or a rotating wheel can also be used as an alternative.

The connecting sleeve 14 is fixedly connected to the surface of the end of the blanking frame 5, and the adjusting screw 8 is threadedly connected to the middle of the connecting sleeve 14.

[0030] Specifically, the setting of the connecting sleeve 14 can support the adjusting screw 8, ensuring the firmness of the threaded connection position with the blanking frame 5 during its rotation. At the same time, it helps to improve the supporting ability and enhance the stability.

[0031] Please refer to Figure 1 , as another specific implementation provided by the application, it further includes scale lines 15. The scale lines 15 are equally spaced on the surfaces on both sides of the blanking frame 5.

[0032] Specifically, the setting of the scale lines 15 can more intuitively observe the adjustment position of the adjusting plate 6, improving the convenience during use.

[0033] Please refer to Figure 1 , as another specific implementation provided by the application, it further includes a control switch 16. The control switch 16 is arranged on one side of the connecting base plate 1. The input end of the control switch 16 is electrically connected to the output end of an external power supply, and the output end of the control switch 16 is electrically connected to the input end of the electric push rod 4.

[0034] Specifically, the setting of the control switch 16 can control the electric push rod 4 to achieve its movement state or speed. A single-chip microcomputer can also be used as an alternative.

The lower end of the discharge pipe 18 corresponds to the blanking frame 5, and the on-off valve 19 is arranged at the upper end of the discharge pipe 18.

[0036] Specifically, during use, the mixing station body 17 is located at the upper end position of the connecting base plate 1. The discharge pipe 18 thereon extends towards the upper end of the blanking frame 5, and the discharge pipe 18 is in contact with the upper surface of the blanking frame 5, enabling the closing baffle 9 to close its lower end during discharging.
