DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present utility model are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0025] like Figure 1-5 As shown, a bulk material loading device comprises a supporting frame 1, a climbing belt conveyor 2 and a weighing belt conveyor 3, wherein the frame of the climbing belt conveyor 2 is fixedly connected to the supporting frame 1. During installation, the supporting frame 1 can be set at a weighbridge, and the vehicle is driven to the weighbridge for loading.

[0026] The weighing belt conveyor 3 is located at the feeding side 4 of the climbing belt conveyor 2, and a discharge hopper 6 is provided on the supporting frame 1, and the discharge hopper 6 is located below the discharge side 5 of the climbing belt conveyor 2. The material is first transported to the feeding side 4 of the climbing belt conveyor 2 by the weighing belt conveyor 3, and then transported to the discharge side 5 by the climbing belt conveyor 2, and finally falls into the discharge hopper 6.

[0027] A liftable material distribution device 7 is provided on the supporting frame 1, and the material distribution device 7 is located below the discharge hopper 6. A control valve 8 and a telescopic discharge pipe 9 are provided at the bottom of the discharge hopper 6. The control valve 8 can be opened to discharge the material in the discharge hopper 6 to the material distribution device 7, and the material is loaded and distributed through the material distribution device 7.

[0028] When in use, the vehicle stops on the scale, then the climbing belt conveyor 2, the weighing belt conveyor 3 and the control valve 8 are turned on; according to the actual situation, the material distribution device 7 is lowered to an appropriate height to distribute the material. As the material is continuously discharged, the material distribution device 7 is raised according to the height of the material in the vehicle. In this way, it can be ensured that the material distribution device 7 maintains an appropriate distance from the bottom of the vehicle, reducing the phenomenon of material spillage and dust during the material distribution process.

[0029] Furthermore, the material distributing device 7 includes a lifting frame 10 and a belt conveyor 11; the frame of the belt conveyor 11 is connected to the lifting frame 10, and a lifting mechanism 12 is provided between the lifting frame 10 and the supporting frame 1, and the lifting frame 10 and the belt conveyor 11 are driven to move up and down by the lifting mechanism 12. The lifting mechanism 12 can be a screw lift or a telescopic cylinder; if a telescopic cylinder is used, at least two telescopic cylinders are provided, and the two ends of the telescopic cylinder are fixedly connected to the frames of the lifting frame 10 and the belt conveyor 11 respectively.

[0030] A driving mechanism is provided on the lifting frame 10, and the driving mechanism drives the belt conveyor 11 to move horizontally and drives the driving roller of the belt conveyor 11 to rotate, thereby driving the belt of the belt conveyor 11 to rotate to achieve material distribution.

[0031] The above-mentioned climbing belt conveyor 2, weighing belt and belt conveyor 11 are all common devices in the prior art, and are mainly composed of a driving roller, a driven roller and a frame. The driving roller and the driven roller are both rotatably connected to the frame, and the belt is wrapped between the driving roller and the driven roller. The climbing belt conveyor 2 and the driving roller in the weighing belt in this device are connected to a motor, that is, the motor drives each belt to rotate. The belt conveyor 11 in the material distribution device 7 is driven by a driving mechanism, and is driven by a motor, which is specifically implemented by the following structure:

[0032] The driving mechanism includes a driving cylinder 13, a driving gear 14 and a driving rack 15; the frame of the belt conveyor 11 is slidably connected to the lifting frame 10, the two ends of the driving cylinder 13 are respectively fixedly connected to the frame of the belt conveyor 11 and the lifting frame 10, the driving gear 14 is coaxially fixed to the active roller, and the driving rack 15 is fixedly connected to the lifting frame 10 and meshed with the driving gear 14. When the driving cylinder 13 is continuously extended and retracted, it can drive the frame of the belt conveyor 11 to move, so that the driving gear 14 and the driving rack 15 are meshed, and then the active roller in the belt conveyor 11 is driven to rotate, thereby realizing the rotation of the belt thereon to perform the material laying operation.

[0033] Furthermore, the lower end of the telescopic discharge pipe 9 is fixedly connected to the lifting frame 10, and the upper end of the telescopic discharge pipe 9 is fixedly connected to the control valve 8. The material flows into the telescopic discharge pipe 9 through the control valve 8. The telescopic discharge pipe 9 can be set with a common telescopic pipe structure, and of course, a bellows can also be used. When the lifting frame 10 moves up and down, the lower end of the telescopic discharge pipe 9 can be driven to move accordingly, so that the distance between the bottom of the telescopic discharge pipe 9 and the belt conveyor 11 is always kept fixed.

[0034] Furthermore, the weighing belt conveyor 3 is located above the feeding side 4 of the climbing belt conveyor 2; a plurality of partitions 16 are evenly distributed on the belt of the climbing belt conveyor 2, and the partitions 16 can contact the belt of the weighing belt conveyor 3; that is, the partitions 16 can scrape off the material attached to the belt of the weighing belt conveyor 3 and transport it out through the climbing belt conveyor 2.

[0035] Furthermore, in order to prevent the material discharged from the climbing belt conveyor 2 from being unevenly distributed in the discharge hopper 6, a discharge hopper 17 is provided between the discharge hopper 6 and the unloading side 5 of the climbing belt conveyor 2. The discharge hopper 17 is slidably connected to the supporting frame 1, and a reciprocating movement mechanism is provided between the discharge hopper 17 and the active roller of the climbing belt conveyor 2.

[0036] The material discharged by the climbing belt conveyor 2 first passes through the discharge hopper 17 and then falls into the discharge hopper 6; the discharge hopper 17 is driven to reciprocate horizontally by the reciprocating mechanism, so that the material can be more evenly distributed in the discharge hopper 6.

[0037] Furthermore, the reciprocating mechanism preferably adopts a crank-connecting rod mechanism, which includes a crank 18 and a connecting rod 19, one end of the crank 18 is fixedly connected to the driving roller of the climbing belt conveyor 2, and the two ends of the connecting rod 19 are respectively rotatably connected to the discharge hopper 17 and the other end of the crank 18. The crank 18 is driven to rotate by the rotation of the driving roller of the climbing belt conveyor 2, thereby realizing the reciprocating movement of the discharge hopper 17.

[0038] Only the preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments.
