Description

Technical Field

[0001] The utility model relates to the technical field of cement production equipment, in particular to a fixed-point feeding system for bulk trucks. Background Art

[0002] Cement is a powdered, hydraulic, inorganic binder. When mixed with water, it forms a slurry that hardens in air or water, firmly binding materials like sand and stone. Early lime-pozzolana mixtures are very similar to modern lime-pozzolana cement. Using it to bind crushed stone, concrete, after hardening, not only offers high strength but also resists erosion by fresh or salt water. It has long been a key binder used in civil engineering, water conservancy projects, and national defense projects.

[0003] During the bulk loading process, the cement powder in the storage tank needs to be guided through a bag tube and sent into a tank truck for loading. However, based on the driver's personal experience, it is difficult to align the feed port and discharge port of the tank truck. Others are needed to help direct the parking, which requires a large amount of manpower and reduces the feeding efficiency. Utility Model Content

[0020] In order to enable people skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0021] The core of this application is to provide a fixed-point feeding system for bulk trucks, which solves the problem that in the existing bulk cement process, the cement powder in the storage tank needs to be guided through a bag tube and sent into the tank truck for loading. However, based on the driver's personal experience, it is difficult to align the feed port and the discharge port of the tank truck, and other people are needed to help direct the parking, which requires a large manpower investment and reduces the feeding efficiency.

[0022] Figure 1 This is a structural diagram of a fixed-point feeding system for bulk vehicles provided by the utility model. Figure 2 This is a schematic diagram of the internal structure of a lower hopper provided by the utility model, see Figures 1 to 2 shown.

[0023] A fixed-point feeding system for bulk trucks includes a support platform 5, a tank truck 14, and a controller. A cement silo 1 is mounted on the support platform 5, supporting and securing the silo 1. An electromagnetic discharge valve is installed at the bottom of the silo, controlling the discharge of cement. The silo 1 is used to store cement powder and can utilize existing technology. A hopper 3 is connected to the bottom of the silo 1 via a cloth bag 2. The hopper 3 extends through the support platform 5. The cloth bag 2 is flexible, allowing the hopper 3 to be raised or lowered by the expansion mechanism, ensuring that the silo 1 and hopper 3 remain connected. A lifting mechanism 4 is connected to the hopper 3 and the silo 1, controlling the raising and lowering of the hopper 3. As the lifting mechanism 4 extends downward, it allows the hopper 3 to be inserted into the feed port 15 of the tank truck 14. After loading is complete, the lifting mechanism 4 is raised, allowing the hopper 3 to exit the feed port 15 of the tank truck 14. The cloth bag 2, the lower hopper 3 and the lifting device 4 are all prior arts and have been fully disclosed, so they will not be described in detail here.

[0024] The hopper 3 and the feeding port 15 of the tank truck 14 are aligned with each other, and the feeding port 15 of the tank truck 14 is aligned with each other, and the feeding port 15 of the tank truck 14 is aligned with each other, and the feeding port 15 of the tank truck 14 is aligned with each other, and the feeding port 15 of the tank truck 14 is aligned with each other, and the feeding port 15 of the tank truck 14 is aligned with each other.

[0025] In order to save resources, when there is no tank truck 14 under the support platform 5 for loading, electrical equipment such as the camera 8 and the display screen 9 are all in the off state. As a preferred embodiment, a first sensor 10 is provided on the rear support column 7. The first sensor 10, the camera 8 and the display screen 9 are all electrically connected to the controller. When a tank truck 14 enters the bottom of the support platform 5, the tank truck 14 first passes the rear support column 7. When the first sensor 10 captures the passing of the vehicle, it transmits the information to the controller, and the controller controls the camera 8 and the display screen 9 to start. It should be noted that the controller can use a PLC module, and the PLC module can realize the control of each component by interacting with the signals of the components electrically connected to it. The interaction between the signals of the PLC module is a prior art that can be easily thought of by those skilled in the art. It is not the focus of this application and is therefore not described in detail here.

[0026] In this embodiment, preferably, a second sensor 11 is provided on the side wall of the discharge hopper 3, and an alarm 12 is also fixedly provided on the front support column 6. The second sensor 11 and the alarm 12 are both electrically connected to the controller. When the second sensor 11 detects that the tank truck 14 is full of cement, the alarm 12 starts to alarm. The driver in the car can know the loading situation and stop discharging materials into the tank truck 14. The lifting device is lifted and the discharge hopper 3 will withdraw from the feed port 15 of the tank truck 14. The driver can drive the tank truck 14 away.

[0027] In order to better remind the driver, as a preferred embodiment, the alarm 12 is a warning light, which is arranged near the display screen 9 and can be seen by the driver after it lights up.

[0028] As a preferred embodiment, a lighting lamp 13 is also mounted on the rear support column 7 to illuminate the loading process, allowing the driver to more clearly see the positional relationship between the lower hopper 3 and the feed port 15. As a preferred embodiment, the lighting lamp 13 is electrically connected to the first sensor 10. When no tank truck 14 is being loaded, the lighting lamp 13 is turned off.

[0029] The present application provides a fixed-point feeding system for bulk trucks. The operating principle is as follows: when loading is actually required, the driver drives the tank truck 14 to the bottom of the support platform 5. The tank truck 14 first passes the rear support column 7. When the first sensor 10 captures the vehicle passing, it transmits the information to the controller, which controls the camera 8 and the display screen 9 to start. The camera 8 captures the position image of the tank truck 14 in real time and eventually displays the image on the display screen 9. The driver can know the relative position between the lower hopper 3 and the feed port 15 of the tank truck 14 by observing the display screen 9, and then quickly adjust the position of the tank truck so that the lower hopper 3 and the feed port 15 are aligned. The lifting device 4 controls the lower hopper 3 to be inserted into the feed port 15 of the tank truck 14. When the second sensor 11 detects that the tank truck 14 is full of cement, the alarm 12 starts to sound, the lifting device 4 is lifted, and the lower hopper 3 will withdraw from the feed port 15 of the tank truck 14.
