Abstract
Description
Technical Field
[0001] This utility model relates to the field of grain storage equipment, and in particular to a quantitative feeding device for grain discharge. Background Technology
[0002] Currently, the loading volume of grain onto trucks is often difficult to control accurately. It's typically estimated based on the initial loading, and then weighed precisely at the point of departure, making further loading or unloading inconvenient. This leads to several problems: underloading wastes space and increases transportation costs, while overloading can result in overloading and compromises transportation safety. Accurately controlling the loading volume requires repeated loading / unloading and weighing, which is inefficient. Furthermore, grain loading often involves multiple conveying and unloading machines working together, such as unloaders, buffer hoppers, horizontal conveyors, and inclined loading conveyors. These machines are usually operated and controlled independently, lacking unified scheduling. Stopping equipment mid-process or at the point of departure requires manual shutdown of each machine, which is cumbersome and poses safety hazards. It also increases the risk of grain scattering or remaining on the conveyor equipment, ultimately affecting the final weight of the loaded grain. Utility Model Content
[0003] To overcome the shortcomings of existing grain feeding devices, such as difficulty in controlling the loading amount and equipment start-up and shutdown when grain is being loaded out of the warehouse, the technical problem to be solved by this utility model is to provide a quantitative feeding device for grain leaving the warehouse that can conveniently control the start-up and shutdown of the equipment and the amount of grain loaded.
[0004] The technical solution adopted by this utility model to solve its technical problem is:
[0005] The grain feeding device includes a weighing conveyor and a controller for controlling the operation of the weighing conveyor. It also includes a power control box electrically connected to the controller. The power control box is equipped with a socket for supplying power to other supporting conveying equipment. The controller is configured to: accumulate the amount of grain conveyed in real time during the grain conveying process, and when the amount of grain conveyed reaches a set threshold, disconnect the circuit of each operating device sequentially from front to back along the conveying path at intervals through the power control box.
[0006] Furthermore, the power control box is divided into a front power control box and a rear power control box, which are respectively located at the front and rear ends of the weighing conveyor. The front power control box is used to connect and control the working equipment located in front of the weighing conveyor, and the rear power control box is used to connect and control the working equipment located behind the weighing conveyor.
[0007] Furthermore, the power control box is equipped with a corresponding knob and indicator light for each socket.
[0008] Furthermore, the controller is equipped with a control panel that can input information and display the grain delivery volume and equipment operating status.
[0009] Furthermore, the controller is also configured to determine whether the equipment is faulty based on the current and voltage status of each socket, and to shut down the working equipment located before and after the faulty equipment via the power control box.
[0010] Furthermore, it also includes a buffer hopper, which is equipped with a material level sensor and a slide valve at the material discharge port of the buffer hopper. Both the material level sensor and the slide valve are electrically connected to a controller. The controller is configured to open the slide valve when the grain in the buffer hopper is higher than the material level sensor, and otherwise close the slide valve.
[0011] The beneficial effects of this utility model are as follows: a weighing conveyor is used as an intermediate device for grain unloading operations, and a power control box is provided to connect and control other supporting operating equipment. During the loading process, the weighing conveyor can record the total amount of grain conveyed in real time, thereby realizing the control of the loading amount. In addition, when the unloading operation is completed, the power control box can automatically shut down each operating device in sequence from the front (grain unloading end) to the back (loading and spreading end) according to the set interval time, thereby avoiding grain residue on the equipment, improving the efficiency of grain unloading and loading and the precise control of the loading amount, while also preventing grain residue on the operating equipment.

[0014] The present invention will be further described below with reference to the accompanying drawings.
[0015] It should be noted that if this utility model contains directional indicators such as up, down, left, right, front, and back, these are used to describe the relative positional relationships between components and are not specific references to the absolute positions of related components or the positional relationships between components. They are only used to explain the relative positional relationships and movement of components in a specific posture. If the specific posture changes, the directional indicator will also change accordingly. If this utility model contains terms related to quantity, such as "many," "multiple," or "several," these specifically refer to two or more.
[0016] like Figure 1As shown, the present invention provides a quantitative feeding device for grain unloading, comprising a weighing conveyor 1 and a controller 2 for controlling the operation of the weighing conveyor 1, and a power control box 3 electrically connected to the controller 2. The power control box 3 is equipped with a socket 33 for supplying power to other supporting equipment. The controller 2 is configured to: record the cumulative grain conveying volume in real time during the grain unloading operation, and when the conveying volume reaches a set threshold, sequentially disconnect the circuits of each operating device at intervals according to the conveying path from the front (grain unloading end) to the back (loading and spreading end). The weighing conveyor 1 is a belt scale, an existing product, which can be selected according to the actual required length and conveying volume. The working principle of the belt scale is to measure the weight and speed of the material through a weighing sensor and a speed sensor, thereby calculating the instantaneous flow rate and cumulative weight of the material. Therefore, using the weighing conveyor 1 as an intermediate device in the grain unloading operation can achieve precise control of the grain loading volume. The power control box 3 mainly supplies power to other equipment, and the socket 33 is a standard part; the plugs of other operating equipment use matching plugs. The hardware and software programs used in the power control box 3 to control the on / off state of each socket 33 circuit are all existing technologies. This application only makes conventional modifications based on the required functions, and will not be described in detail here.
[0017] The usage process of this utility model is as follows: First, select appropriate operating equipment based on the distance from the grain depot door to the vehicle. This generally includes a grain unloader at the front for feeding, a conventional conveyor to deliver the grain outside the depot, and an inclined loading conveyor at the rear for loading the grain onto the vehicle. The weighing conveyor 1 can be positioned between the conventional conveyor and the inclined loading conveyor. Then, connect the weighing conveyor 1 to the main power supply, and connect the power plugs of the other operating equipment to the socket 33 on the power control box 3 of the weighing conveyor 1. Next, set a conveying capacity threshold based on the vehicle's load capacity and the estimated total accumulation of grain on each operating device during normal transport. The value should be the vehicle's load capacity minus the total amount of grain piled up. This threshold is entered into controller 2, and a stop interval time is set. This interval time can be set separately based on the time it takes for the grain to pass through each operating device, or a uniform time can be set. Finally, controller 2 starts the operation of each operating device to carry out the grain unloading and loading operation. The weighing conveyor 1 accumulates the conveyed amount in real time and sends it to controller 2. When controller 2 determines that the workload has reached the set threshold, it first controls the grain unloader to stop working. After a set time interval, the regular conveyor is shut down. This process is repeated, shutting down weighing conveyor 1, tilting loading conveyor, etc., sequentially from front to back along the conveying path. In addition, during the grain conveying process, the grain unloader may need to be changed and stopped midway. In this case, the operator can manually operate controller 2 to pause the conveying. Controller 2 will also shut down each operating device sequentially according to the above process, but weighing conveyor 1 will not be shut down. Controller 2 records the amount of grain that has been conveyed, and then restarts the machine to measure the grain again.
[0018] Using this utility model as an intermediate device for grain loading and unloading operations, the weighing conveyor 1 can record the total amount of grain conveyed in real time during the loading process, thereby controlling the loading amount. When the loading operation is completed, the power control box 3 can automatically shut down each conveying device in sequence from front to back according to the set interval time, thereby avoiding grain residue on the equipment and improving the efficiency of grain loading and unloading and the precise control of the loading amount.
[0019] To facilitate the connection of various working devices and avoid the cross-laying of power lines, this utility model divides the power control box 3 into a front power control box 31 and a rear power control box 32, which are respectively set at the front and rear ends of the weighing conveyor 1. The front power control box 31 is used to connect and control the working devices located in front of the weighing conveyor 1, and the rear power control box 32 is used to connect and control the working devices located behind the weighing conveyor 1.
[0020] When connecting the power cords of other conveying equipment to the power control box 3, to facilitate determining whether the circuit is connected, a corresponding knob and indicator light can be installed on the power control box 3 for each socket 33. The knob is used to manually connect the power cord to the power control box 3, and the indicator light indicates whether the circuit is connected by turning on and off. During equipment operation, the indicator light can also change colors to indicate different operating states. For example, it is green during normal operation, and when the conveying equipment malfunctions, it may cause changes in current or voltage in the circuit. In this case, the corresponding indicator light can turn red to indicate the situation, allowing staff to take timely action.
[0021] To make the grain conveying process more intelligent and visualized, the preferred embodiment of this utility model is that the controller 2 is equipped with a control screen 21 that can input information and display the grain conveying volume and equipment operating status. During grain conveying, staff can observe the information displayed on the control screen 21 at any time to understand the conveying status and perform corresponding operations such as starting, pausing, or stopping the machine. The controller 2 is also configured to determine whether the equipment has malfunctioned based on the current and voltage status of each socket 33 and display the information on the control screen 21. At the same time, the conveying equipment located before the malfunctioning equipment can be shut down through the power control box 3, thereby preventing grain overflow or further expansion of the fault area. In addition, a continuous power supply mode can be set through the control screen 21. In this mode, the sockets 33 of the power control box 3 are continuously powered, and other equipment will not be automatically shut down even if equipment malfunctions, facilitating equipment maintenance.
[0022] During the grain unloading process, the movement of the unloader and the raising and lowering of the unloader head can cause fluctuations in the grain flow. Since the weighing conveyor 1 accumulates the grain conveying volume primarily by measuring the weight and speed of the material, ensuring a stable flow rate of grain into the weighing conveyor 1 is crucial for precise control of the grain conveying volume. To address this, a preferred embodiment of this invention is a separate buffer hopper 4 at the feed end of the weighing conveyor 1. The buffer hopper 4 contains a level sensor 41, and a gate valve 42 is located at the discharge port of the buffer hopper 4. Both the level sensor 41 and the gate valve 42 are electrically connected to a controller 2. The controller 2 is configured to open the gate valve 42 when the grain in the buffer hopper 4 is higher than the level sensor 41, and close the gate valve 42 otherwise. This ensures that the grain in the buffer hopper 4 only flows out after accumulating to a certain height, guaranteeing the stability of the grain flow rate and reducing weighing errors caused by frequent flow rate changes.
