Description

Technical Field

[0001] The utility model relates to the field of bulk loaders, in particular to an automatic loading device for bulk loaders. Background Art

[0002] When discharging material from a bulk feeder, the driver first drives the truck under the opening of the telescopic feed tube. The operator then uses a remote control to lower the tube into the truck bed. The control gate then opens, and the barrel begins discharging material. During this process, the telescopic feed tube is raised according to the height of the pile, preventing material from accumulating at the opening of the tube and affecting smooth discharge. When the operator confirms that the material is flush with the upper edge of the bed, the control gate closes, prompting the driver to move the truck, and then continuing to discharge material to other areas of the bed. However, bulk feeder operations generate dust. This dust can become airborne and be inhaled by the operator. Long-term accumulation can cause respiratory diseases such as pneumoconiosis, seriously endangering the operator's health. Utility Model Content

[0003] The purpose of the utility model is to provide an automatic loading device with a simple structure and a high degree of automation, which can avoid direct contact of operators with dust and prevent harm to human health and safety.

[0004] The purpose of the utility model can be achieved through the following technical solutions:

[0005] An automatic loading device for a bulk material machine, the bulk material machine includes a frame, a barrel arranged on the frame, a rangefinder arranged on a bracket next to the barrel for measuring the height of the pile, and a controller; a gate for opening or closing the discharge port is provided in the discharge port at the bottom of the barrel; a gate drive device connected to the gate is fixed on the frame; a telescopic material pipe is connected to the discharge port; a telescopic drive device for driving the telescopic material pipe to be extended and retracted is provided on the frame; an automatic loading device is provided in a truck channel formed at the lower part of the frame; the automatic loading device includes an in-position sensor for detecting the position of the truck compartment, a height sensor for detecting the height of the truck compartment, and a control switch for controlling the activation of all sensors; the gate drive device, the telescopic drive device, the rangefinder and the automatic loading device are all electrically connected to the controller.

[0006] With this technical solution, when a truck enters the truck lane, a control switch is activated. When the sensor detects the truck compartment's position and height, it transmits a signal to the controller, which in turn controls the telescopic drive mechanism to lower the telescopic feed tube into the truck compartment, beginning unloading. A rangefinder measures the material pile height in real time, controlling the telescopic drive mechanism in conjunction with the telescopic drive mechanism. This allows the telescopic feed tube to be raised accordingly, preventing material accumulation at the tube opening, which could affect unloading. When the rangefinder measures the material accumulation reaching a preset height relative to the truck compartment, a signal is transmitted to the controller, which closes the gate and stops unloading.

[0007] In a specific implementation manner of the present utility model: the in-position sensor is a horizontal grating arranged on both sides of the truck channel, and the height measuring sensor is a vertical grating arranged on both sides of the truck channel.

[0008] In a specific implementation manner of the present utility model: the number of the transverse gratings is 3 pairs.

[0009] In a specific implementation manner of the present utility model: the truck channel is provided with a plurality of stop positions.

[0010] In a specific embodiment of the present invention, a voice prompt device is also installed on the frame, and the voice prompt device is connected to the controller via an electric wire. With the above technical solution, the driver is reminded by the voice prompt device that the shifting and loading are completed.

[0011] In a specific implementation manner of the present utility model: the rangefinder is an ultrasonic rangefinder or an infrared rangefinder.

[0012] In summary, the utility model has a simple structure and a high degree of automation, which can prevent operators from being directly exposed to dust and prevent harm to human health and safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] Figure 1 The utility model is a structural schematic diagram of an automatic loading device for a bulk material machine. DETAILED DESCRIPTION

[0015] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] See also Figure 1As shown, the utility model is an automatic loading device for a bulk material machine. The bulk material machine 10 includes a frame 11, a barrel 12 arranged on the frame 11, a rangefinder (not shown in the figure) arranged on the bracket 11 next to the barrel 12 for measuring the pile height, and an automatic loading device 13.

[0017] A discharge port 14 is provided at the bottom of the barrel 12. A gate 15 for opening or closing the discharge port is provided in the discharge port 14. A gate drive 16 for driving the gate 15 is installed on the frame. The gate drive 16 is driven by a cylinder.

[0018] A telescopic material tube 17 is connected to the discharge port 14. A telescopic drive device 19 is provided on the frame 11 to drive the telescopic material tube 17 to extend and retract. In this embodiment, the telescopic drive device is a winch. The winch's traction rope is connected to the telescopic material barrel. A motor drives the reel to rotate, winding the traction rope to achieve telescopic expansion and contraction of the telescopic material barrel. This telescopic drive device is prior art and is disclosed in Patent CN214494443U, so it will not be described in detail here.

[0019] In this embodiment, the rangefinder is an ultrasonic rangefinder or an infrared rangefinder.

[0020] A controller (not shown) is also mounted on the frame 11. The gate drive 16, the telescopic drive 19 and the rangefinder are all electrically connected to the controller.

[0021] The lower portion of the frame 11 forms a truck passageway. An automatic loading device 13 is installed within the truck passageway and includes an in-place sensor 9 for detecting the position of the truck compartment, a height sensor 8 for detecting the height of the truck compartment, and a control switch 18 for activating all sensors. This control switch 18 and all sensors are electrically connected to a controller.

[0022] In addition, a voice prompt device 20 is also installed on the frame. The voice prompt device 20 is connected to the controller through an electric wire.

[0023] In this embodiment, the position sensors 9 are transverse gratings arranged on both sides of the truck passage, and the height sensors are vertical gratings 8 arranged on both sides of the truck passage.

[0024] In this embodiment, the number of transverse gratings is set to three pairs. These three pairs of transverse gratings enable real-time detection of the position of the arriving truck compartment. The front pair of transverse gratings, the middle pair of gratings, and the rear pair of gratings respectively monitor the front, middle, and rear of the truck compartment. Thus, when the vehicle stops, if the compartment does not cover the front transverse gratings, the controller determines that the truck has not stopped properly and a voice message continues to be broadcast, reminding the truck driver to continue driving forward. The middle gratings act as a switch during the loading process. If the middle transverse gratings detect a data change, the controller will cause the bulk material conveyor to an emergency stop to prevent abnormal situations such as slipping. The rear pair of gratings is configured to determine the end of loading. When the rear pair of gratings detects a complete open circuit or a data change, loading is complete. The controller controls the gate to close, and the telescopic material tube 17 returns to its initial position. Simultaneously, a voice message announces the end of loading, reminding the truck driver to drive away.

[0025] In the present embodiment, three stop positions are provided on the truck channel. When the truck stops at the first stop position, the truck driver can just touch the control switch 18.

[0026] During operation, when the truck reaches the first stop position in the truck lane, the driver touches the control switch 18, and all light barriers are activated. When the light barriers detect the position and height of the car body, they transmit a signal to the controller. The controller controls the telescopic drive device to drive the telescopic material tube 17 down into the car body, and then controls the gate 15 to open and start discharging the material. The distance meter measures the height of the pile in real time and controls it in conjunction with the telescopic drive device. The height of the telescopic material tube 17 can be raised accordingly according to the height of the pile, thereby avoiding material accumulation at the tube mouth of the telescopic material tube 17, which affects the smooth discharge of the material and achieves dust-free discharge. When the distance meter measures that the height of the material has accumulated to the preset height of the measured truck body, it transmits a signal to the controller, which controls the gate 15 to close, stop discharging the material, and raise the tube mouth of the telescopic material tube to the highest point.

[0027] Afterwards, the voice prompt device 20 reminds the driver to move the truck 7 to the next stop position. After all the transverse gratings sense the truck and transmit the signal to the controller, the above steps are continued to discharge the material. When the rangefinder measures that the height of the pile is flush with the height of the carriage, it transmits the signal to the controller. The controller controls the gate 15 to close, stops discharging the material, and controls the voice prompt device 20 to emit a prompt sound. After hearing the voice prompt, the driver moves the truck 7 to the last stop position and continues the above steps. When the material in the carriage of the truck 7 is full, the voice prompt device 20 emits a prompt sound, and the driver drives the truck 7 away. During the process of the truck moving forward, a pair of transverse gratings on the rear side detect that the circuit is completely open or the data has changed. The controller controls all sensors to close, and the automatic loading operation ends.

[0028] In summary, the utility model has a simple structure and a high degree of automation, which can prevent operators from being directly exposed to dust and prevent harm to human health and safety.

[0029] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
