Description

Technical Field

[0002] Currently, farms, docks, stations, and large grain depots transport granular materials, including grain, plastic, and other small particles, during loading and unloading, replenishing and unloading, unloading, turning over, and stacking. Most of these materials are handled manually. However, manual loading and unloading, including bagged transport, is time-consuming, labor-intensive, and requires high packaging costs for short distances, significantly increasing costs. Furthermore, the loading and unloading process generates significant dust, which, if released directly into the air, can pollute the environment and even threaten the health of workers. Utility Model Content

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Figure 1It is a structural schematic diagram of the mobile material conveying device of the present utility model. DETAILED DESCRIPTION

[0018] 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.

[0019] See also Figure 1 As shown, the present invention is a mobile material conveying device, comprising a mobile gantry 10, a first separation mechanism 20, a second separation mechanism 30 and a vacuum power mechanism 40 provided on the mobile gantry 10. In this embodiment, the vacuum power mechanism 40 is a Roots blower or a centrifugal blower.

[0020] The gantry 10 is a rectangular frame. Multiple slide rails are located beneath the gantry 10. Travel wheels 101 are located at the bottom of the gantry 10 and engage with the slide rails. A longitudinal drive mechanism 11 is connected to one side of the gantry 10 to drive the gantry 10 longitudinally. The longitudinal drive mechanism 11 can be driven by a motor, hydraulics, or a cylinder. In this embodiment, the longitudinal drive mechanism is driven by a cylinder.

[0021] The first separation mechanism 20 includes a material collection bin 21 and a first separator 22 located above the material collection bin 21. A telescopic material pipe 23 is connected to the side of the first separator 22. A material conveying line 26 is provided just below the material collection bin 21.

[0022] In this embodiment, the telescopic material tube 23 includes a hose section 235 located at the upper portion, a telescopic section 236 located at the middle portion, and a suction nozzle 237 located at the lower portion.

[0023] The movable gantry 10 is provided with a telescopic drive mechanism for driving the telescopic material tube 23 to extend and retract, and a transverse drive mechanism for driving the telescopic material tube to move transversely.

[0024] The telescopic drive mechanism includes a mobile bracket 231 and a telescopic cylinder 232 located at the telescopic section 236. A transverse slide rail (not shown) is provided at the top of the mobile gantry 10, and the mobile bracket 231 is slidably mounted on the transverse slide rail. The telescopic cylinder 232 is vertically fixed to the upper end of the mobile bracket 231. The telescopic cylinder 232 has a piston rod 2321 extending downward. The upper end of the telescopic section 236 is fixed to the top of the mobile bracket 231, and the lower end is connected to the end of the piston rod 2321. In this way, the telescopic cylinder 232 drives the piston rod 2321 to extend and retract, thereby driving the telescopic material tube 23 to extend and retract.

[0025] The transverse drive mechanism comprises a rack 233 and a motor 234, mounted transversely to the upper end of the mobile gantry 10. The motor 234 is fixed to the mobile support 231. A motor gear is mounted on the output end of the motor 234, meshing with the rack 233. As the motor 234 drives the motor gear, its rotational motion is transmitted to the rack 233 through meshing. Because the rack 233 is fixed to the mobile gantry 10, its movement is restricted, converting its motion into linear motion of the mobile support 231 on the transverse rails. The suction nozzle 237 also moves with the movement of the mobile support 231.

[0026] In this embodiment, the first separator 22 is an inertial separator.

[0027] The second separation mechanism 30 includes a second separator 31 and an impurity bin 32 located below the second separator 31 .

[0028] In this embodiment, the second separator 31 is a bag separator.

[0029] The first separator 22 , the second separator 31 and the vacuum power mechanism 40 are connected via a vacuum pipe 9 .

[0030] The system also includes a controller and an identification unit. In this embodiment, the identification unit is a camera 12. The camera 12 and all drive mechanisms are electrically connected to the controller. The identification unit measures the material height and position in real time, and controls all drive mechanisms in conjunction with the control unit. This allows the telescopic material tube's suction nozzle to be lowered and laterally moved accordingly, while also controlling the position of the mobile gantry to adjust its position, thereby achieving automatic material suction.

[0031] In addition, the truck passage formed at the bottom of the mobile door frame 10 is also provided with a vehicle arrival sensor 13. The arrival sensor 13 is connected with the controller wire. In the present embodiment, the arrival sensor 13 is a transverse grating arranged on both sides of the truck passage.

[0032] The above is a mobile material conveying device, and its specific working principle is as follows:

[0033] When a vehicle loaded with materials enters the truck lane below the mobile gantry 10, the arrival sensor 13 senses the vehicle 8 and transmits a signal to the controller. The controller controls the telescopic drive mechanism to lower the telescopic feed tube 23, allowing the suction nozzle of the telescopic feed tube 23 to enter the vehicle compartment. Subsequently, the vacuum mechanism 40 is activated, and the suction nozzle of the telescopic feed tube 23 begins to suck the material. During material conveying, the vacuum mechanism 40 generates negative pressure, which draws the material and a certain amount of air through the suction nozzle of the telescopic feed tube 23 and delivers it through the telescopic feed tube 23 to the first separation mechanism 20. The material is intercepted by the inertial separator, separated from the air mixture, and then falls through the first rotary discharge valve 27 at the bottom of the collection bin 21, entering the material conveyor line 26, and then being transported to the silo (not shown). The first rotary discharge valve 27 maintains negative pressure inside the inertial separator above while discharging the material. The air mixture then flows from the upper portion of the inertial separator through the vacuum pipe 9 and into the second separation mechanism 30. The impurities and dust in the air mixture will be separated by the bag separator and fall into the impurity bin 32 from the second rotary discharge valve 28 at the bottom of the bag separator, while the clean air is discharged into the atmosphere from the exhaust port of the vacuum power mechanism 40. The second rotary discharge valve 28 can maintain the negative pressure inside the bag separator above.

[0034] As the material is gradually sucked away, the controller uses the camera 12 to scan the interior of the carriage and transmit signals. After intelligently identifying the location of the remaining material, the controller controls the telescopic drive mechanism and the transverse drive mechanism to cooperate, driving the suction nozzle of the telescopic material tube 23 to move to another position and suck the material. As the material in that area is sucked away, the controller controls the longitudinal drive mechanism 11 to drive the movable gantry 10 to move, thereby sucking away all the material in other areas of the carriage.

[0035] In summary, the present invention sequentially connects an inertial separator, a bag separator, and a Roots blower through a single vacuum pipe, allowing the separation of the material from the air to directly remove dust from the air, thereby reducing impurities in the material and improving its quality. The controller is electrically connected to the camera and all drive mechanisms, using the camera to measure the material's height and position in real time. It also controls the control of all drive mechanisms, lowering and laterally moving the suction nozzle of the telescopic material pipe according to the material's height and position, while also controlling the position of the mobile gantry for adjustment. This enables automatic material suction, significantly improving suction efficiency and saving labor.

[0036] 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.
