Description
Technical Field
[0001] The utility model relates to the field of sand and gravel aggregate loading, in particular to an intelligent loading and metering silo. Background Art
[0002] After the production of sand and gravel aggregates, the traditional loading method is: the bulk materials in the finished material bin are transported to the belt conveyor scale on the loading platform through a belt conveyor. After being measured by the belt scale, the materials are unloaded onto the transport vehicle under the loading platform.
[0003] However, the traditional loading method has the following disadvantages:
[0004] 1. The belt scale has only one unloading point. In order to load the materials evenly into the transport box, the vehicle needs to be moved forward and backward during the loading process;
[0005] 2. During the loading process, moving vehicles often cause material spillage and vehicle collisions, threatening the safety of the production site;
[0006] 3. The loading time is greater than or equal to the running time of the belt conveyor for material transportation, and the belt conveyor cannot run before the car stops at the loading position, resulting in a waiting phenomenon, a long overall loading time and low work efficiency;
[0007] 4. Belt scale is a flow scale. The quality of the material is calculated by the size of the material flow on the belt. This measurement method has poor accuracy. Utility Model Content
[0008] The purpose of the utility model is to overcome the shortcomings of the prior art and to provide an intelligent loading and metering silo, which can evenly load materials onto the vehicle without the need for the vehicle to move during the loading process, and will not cause material spillage or vehicle collision incidents; there is no waste of loading time, which shortens the loading time and improves work efficiency; it is simple and reliable and improves metering accuracy.
[0009] The purpose of the utility model is achieved through the following technical solutions: an intelligent loading and metering silo, including a frame and a controller, a feeding belt conveyor is fixed on the frame, a silo body with a weighing sensor is installed on the frame below the feeding belt conveyor, the silo body is fed by the feeding belt conveyor, the weighing sensor monitors the material weight in the silo body in real time, and sends the material weight signal to the controller, a plurality of discharge ports are provided at the lower part of the silo body, and an electro-hydraulic gate valve controlled by the controller to open and close is installed on each discharge port for unloading to a transport vehicle; the controller also controls the feeding belt conveyor to open or close the feeding through a signal.
[0010] As a further technical solution, the silo body is arranged below the discharge port of the feeding belt conveyor.
[0011] As a further technical solution, a loading space is provided in the frame below the electro-hydraulic gate valve for parking the loading vehicle.
[0012] As a further technical solution, when the last loading vehicle leaves the loading space and the next loading vehicle has not yet entered the loading space, the controller starts the feeding belt conveyor until the silo body is filled with materials.
[0013] As a further technical solution, the full mass of the silo body after being filled with materials is constant, and the mass of the loaded materials on the loading vehicle = the full mass of the silo body after being filled with materials - the remaining mass of the silo body after loading measured by the weighing sensor.
[0014] As a further technical solution, it also includes a monitor, which is arranged between the bottom of the electro-hydraulic gate valve and the loading space. The monitor is used to monitor the opening and closing status of the electro-hydraulic gate valve in real time and send it to the controller; the monitor is also used to monitor the loading vehicle conditions in the loading space in real time and send it to the controller.
[0015] As a further technical solution, the number of the electro-hydraulic gate valves is five in each row, for a total of ten, and their opening and closing are independently controlled by a controller.
[0016] The beneficial effects of the utility model are:
[0017] 1. During the loading process, the vehicle can be evenly loaded with materials without moving, avoiding material spillage and vehicle collision caused by moving vehicles;
[0018] 2. The silo loading solution is that the belt will quickly fill the silo from the time the last vehicle is loaded to the time the next vehicle enters the site for loading. There is no waiting time for vehicles to enter the site, and there are multiple unloading ports under the silo for simultaneous unloading, which greatly shortens the loading time and improves work efficiency.
[0019] 3. The metering principle adopted is: loading material mass = full warehouse mass - remaining mass; it is simple, reliable and has high metering accuracy;
[0020] 4. Simplify the loading process, eliminate the belt scale, reduce production costs, and be more energy-saving, low-carbon and environmentally friendly;
[0021] 5. Multiple electro-hydraulic gate valves are used, which are independently opened and closed by the controller. During loading, the loading can be controlled to be uniform without moving the vehicle, thus improving the loading efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The utility model will be described in detail below with reference to the accompanying drawings:
[0027] Example: As attached Figures 1 to 3 As shown, an intelligent loading and metering silo includes a frame 1, a feeding belt conveyor 2, a silo body 3, a weighing sensor 4, an electro-hydraulic gate valve 5, a monitor 6, a controller 7, a discharge port 8 and a loading space 9.
[0028] Reference Figure 1 A feeding belt conveyor 2 is fixedly mounted on the frame 1, and a silo body 3 with a weighing sensor 4 is mounted on the frame 1 below the feeding belt conveyor 2. Preferably, the silo body 3 is arranged below the discharge port of the feeding belt conveyor 2, and the feeding is realized through the feeding belt conveyor 2. The weighing sensor 4 can monitor the weight of the material in the silo body 3 in real time, and send the material weight signal to the controller 7 (preferably, the controller 7 can be a PLC controller or other intelligent control equipment). The lower part of the silo body 3 is provided with five discharge ports 8 in each row, a total of ten discharge ports 8, and an electro-hydraulic gate valve 5 is correspondingly installed on each discharge port 8 for unloading to the transport vehicle, wherein each electro-hydraulic gate valve 5 can be independently controlled by the controller 7 to open and close, thereby ensuring uniform loading, without moving the vehicle, and improving the loading efficiency.
[0029] Furthermore, a loading space 9 is provided in the frame 1 below the electro-hydraulic gate valve 5 for parking the loading vehicle. When the last loading vehicle leaves the loading space 9 and the next loading vehicle has not yet entered the loading space 9, the controller 7 starts the feeding belt conveyor 2 through signal control until the silo body 3 is filled with materials. The full silo mass after the silo body 3 is filled with materials is constant, and the loading material mass of the loading vehicle = the full silo mass after the silo body 3 is filled with materials - the remaining mass of the silo body 3 after the loading vehicle is loaded as measured by the weighing sensor 4. The loading amount of the loading vehicle each time can be set according to the size of the vehicle model, and can be different each time.
[0030] Preferably, it also includes a monitor 6 (which can be a monitoring camera or other intelligent monitoring equipment), such as Figure 1As shown, the monitor 6 is arranged between the lower part of the electro-hydraulic gate valve 5 and the loading space 9, and the monitor 6 can monitor the opening and closing state of the electro-hydraulic gate valve 5 in real time and send it to the controller 7. In addition, the monitor 6 can also monitor the loading vehicle situation in the loading space 9 in real time and send it to the controller 7.
[0031] The working process of the utility model is as follows: the feeding belt conveyor 2 feeds the material to the silo body 3, and the weighing is carried out by the weighing sensor 4, and the data is transmitted to the controller 7. When the silo body 3 is full (i.e. the feeding reaches the set value), the controller 7 sends a stop feeding instruction to the feeding belt conveyor 2 (thereafter, during the loading process, the feeding belt conveyor 2 will no longer be opened until all the electro-hydraulic gate valves 5 at the bottom of the silo are closed before opening). When the transport vehicle stops at the specified position below the silo body 3 (i.e. the loading space 9), the monitor 6 sends a loading signal to the controller 7. After receiving the signal from the monitor 6, the controller 7 sends an instruction to open the electro-hydraulic gate valves 5 at the bottom of the silo (5 in each row, a total of 10, and each can be opened and closed separately), and opens the electro-hydraulic gate valves 5 at the bottom of the silo to start loading. After that, the monitor 6 monitors the material status in the car box in real time, and sends a signal to the controller 7. The controller 7 sends an instruction to any specified electro-hydraulic gate valve 5 at the bottom of the silo in real time to ensure that the material is loaded evenly. The weighing sensor 4 transmits data to the controller 7 in real time. When the vehicle reaches the set loading volume, the controller 7 issues a closing command to the electro-hydraulic gate valve 5 at the bottom of the silo. When all the electro-hydraulic gate valves 5 at the bottom of the silo are closed (one vehicle is loaded), the electro-hydraulic gate valves 5 at the bottom of the silo feedback a signal to the controller 7. After receiving the signal, the controller 7 issues an opening command to the feeding belt conveyor 2. The feeding belt conveyor 2 starts to feed the silo body 3 and fills the silo body 3 before the front vehicle leaves and the rear vehicle stops at the specified position (i.e., the loading space). A loading cycle ends.
[0032] It is understandable that, for those skilled in the art, any equivalent replacement or change to the technical solution and the concept of the utility model should fall within the protection scope of the claims attached to the utility model.
