[0002] At present, after oil extraction in a grain and oil factory, a large amount of slag will be generated. The slag needs to be transported through pipelines and then through a discharge hopper to the carriage of a loading vehicle. Specifically, during the loading process, the loading vehicle needs to be driven under the discharge hopper first, and then the material is dropped into the carriage of the loading vehicle through the discharge hopper. After the current position is loaded, since the position of the discharge hopper is fixed, the loading vehicle needs to be moved to gradually load the rear position of the carriage. Finally, until the carriage is full of materials, a shielding cloth needs to be covered on the carriage to ensure the effect of temporary storage of materials.

[0024] See Figure 1, A discharging and loading device, comprising: a loading truck 100, a loading area, a first detector 300, a prompting module and a second detector. Among them, the loading truck 100 is provided with a carriage 110 for temporarily storing materials. A plurality of crossbars 111 are arranged at intervals on the upper end of the carriage 110. A waiting-to-be-loaded area is formed between two adjacent crossbars 111. The crossbars 111 are used for installing a shielding cloth; An unloading hopper 200 is fixedly arranged above the loading area. The unloading hopper 200 is provided with a switch member for turning on and off the material output. The switch member is electrically connected to a controller; The prompting module is arranged in front of the loading area. The prompting module is electrically connected to the controller; The first detector 300 is arranged on the side wall of the loading area. The first detector 300 is electrically connected to the controller. When the first detector 300 detects the crossbar 111 to form a first signal, the controller controls the switch member to open the unloading hopper 200, and the controller controls the prompting module to generate a reminder signal for prompting the loading truck 100 to stop; The second detector 400 is arranged above the loading area. The second detector 400 is electrically connected to the controller. When the second detector 400 detects that the materials in the carriage 110 reach a set height to form a second signal, the controller controls the switch member to close the unloading hopper 200, and the controller controls the prompting module to generate a reminder signal for prompting the loading truck 100 to drive.

[0025] For the discharging and loading device with the above structure, during use, the driver drives the loading truck 100 into the loading area. Then the first detector 300 detects the position of the crossbar 111 to form a first signal, and the controller controls the prompting module to generate a first reminder signal, thereby prompting the driver to stop the driving of the loading truck 100. At the same time, the lower end of the unloading hopper 200 faces the corresponding waiting-to-be-loaded area, and the controller controls the switch member to open the unloading hopper 200, so that the materials can be conveyed to the waiting-to-be-loaded area. Then the second detector 400 detects that the materials in the carriage 110 reach a set height to form a second signal, the controller controls the switch member to close the unloading hopper 200, and at the same time the controller controls the prompting module to generate a second reminder signal, thereby prompting the driver to continue driving the loading truck 100. Finally, repeat the above steps to fill the multiple waiting-to-be-loaded areas with materials in turn to complete the material loading, without adding additional personnel for reminding, thereby reducing the labor cost and being beneficial to improving the automation degree of loading. Among them, the existing crossbars 111 provided on the loading truck 100 are used to divide the filling area of the carriage 110, and the position of the crossbar 111 is detected by the first detector 300, so as to facilitate the materials to pile up in the corresponding loading area, which is beneficial to improving the loading efficiency.

[0026] See Figure 1, Further, the second detector 400 is a weight sensor. The weight sensor is connected to a material contact member 410, and the material contact member 410 is connected to a moving mechanism. The moving mechanism is configured to drive the material contact member 410 to move in the vertical direction. Specifically, when the loading vehicle 100 moves to the corresponding loading position, the material contact member 410 first moves to a set height, then the material is filled into the area to be loaded and gradually accumulates into a mountain. Finally, the material contact member 410 contacts the material, so that part of the gravity of the material contact member 410 is supported and offset by the material, thereby enabling the weight sensor to sense a change in weight. Furthermore, the weight sensor feeds back a signal to the controller, enabling the controller to control the switch member to close the discharge hopper 200, which is conducive to stopping the conveying of the material when it reaches the set height, thereby preventing the material from overflowing from the carriage 110. It is also conducive to the controller controlling the prompting module to generate a second reminder signal to prompt the driver to continue driving the loading vehicle 100.

[0027] See Figure 1 , Further, the moving mechanism includes a winding wheel 420. The winding wheel 420 is located above the carriage 110. A lifting rope 430 is wound around the winding wheel 420. One end of the lifting rope 430 is connected to the weight sensor. A connecting rope is provided between the weight sensor and the material contact member 410. The winding wheel 420 is drivingly connected to a first motor that drives it to rotate, and the first motor is electrically connected to the controller. Specifically, when the loading vehicle 100 moves to the corresponding loading position, the controller controls the first motor to rotate forward, so that the winding wheel 420 pays out the lifting rope 430, thereby causing the material contact member 410 to descend to the corresponding height. When the material reaches the set height, the controller controls the first motor to rotate in reverse, so that the winding wheel 420 winds up the lifting rope 430, thereby causing the material contact member 410 to rise to the initial position. Among them, the method of driving the winding wheel 420 by a motor is conducive to changing the lifting stroke of the material contact member 410 by controlling the number of turns of the winding wheel 420, thereby facilitating improving the movement accuracy of the material contact member 410. In some embodiments, the moving mechanism can also be replaced by a method of driving a screw by a motor. One end of the screw is connected to the weight sensor and the material contact member 410 in sequence through a rope, thereby driving the movement of the material contact member 410 through the screw.

[0028] See Figure 1 , Further, the material contact member 410 has a conical structure. The tip of the material contact member 410 can face downward toward the carriage 110, so as to facilitate the material contact member 410 to pierce into the material with the tip, which is conducive to the material better supporting part of the gravity of the material contact member 410, thereby facilitating the weight sensor to sense the weight change and facilitating the controller to make a quick response.

[0029] See Figure 1, Further, the prompting module includes indicating lights 500 in three colors: red, yellow, and green. Specifically, when the first detector 300 detects the position of the crossbar 111 to form a first signal, the controller controls the indicating light 500 to display red, thereby prompting the loading vehicle 100 to stop. When the second detector 400 detects that the materials in the carriage 110 reach the set height to form a second signal, the controller controls the indicating light 500 to display green, thereby prompting the loading vehicle 100 to continue driving. Among them, during the process of conveying the materials to the carriage 110, the controller controls the indicating light 500 to display yellow, so as to facilitate prompting the driver that the carriage 110 is in the loading stage. Through the changing colors of the indicating light 500, it is beneficial for the driver to make different operations according to the changing colors of the indicating light 500.

[0030] See Figure 1 , Further, the prompting module further includes a buzzer electrically connected to the controller. When the indicating light 500 shows red and the loading vehicle 100 is driving, the buzzer emits a sound, so as to facilitate reminding the driver to continue driving the loading vehicle 100 through the sound and red light. It can be understood that the controller can control the sounding time of the buzzer through the input program, so that the buzzer can automatically stop sounding after sounding for a certain time.

[0031] See Figure 1 , Further, the first detector 300 is a transmissive photoelectric switch. The transmissive photoelectric switch includes a transmitter and a receiver, and the transmitter and the receiver are respectively installed on two opposite side walls of the loading area. Specifically, the light emitted by the transmitter directly enters the receiver. When the crossbar 111 passes between the transmitter and the receiver, the light is blocked, so that the transmissive photoelectric switch generates a switching signal, with a fast response time, which is beneficial for the controller to control the prompting module to emit a sound.

[0032] Further, the controller is a PLC controller, and the PLC controller is electrically connected to a display screen, so as to display the output situation of the hopper 200 through the display screen.

[0033] Further, the switching member is a butterfly valve, and the butterfly valve is connected to a second motor, and the second motor is used to drive the butterfly plate of the butterfly valve to rotate. Specifically, the butterfly plate of the butterfly valve is disc-shaped, and the second motor drives the butterfly plate to rotate around its own axis, so as to achieve the function of opening, closing or adjusting the material output inside the hopper 200.

[0034] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0035] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
