The support frame 1 comprises two support rods 101 arranged on both sides of the temporary grain storage hopper 2, that is, the support rods 101 are located above the weighbridge and extend along the length direction of the grain transport vehicle, in this embodiment, the extension direction of the support rods 101 is the same as the arrangement direction of the two temporary grain storage hoppers 2. The two ends of the support rod 101 are connected by a connecting rod 104, so that the support rod 101 and the connecting rod 104 are enclosed to form a rectangular structure, the end of the support rod 101 is fixedly connected to the end of the corresponding connecting rod 104, and the connection method of the two is integrated connection, bolt connection or welding, in this embodiment, the connection method of the two is welding. A plurality of support legs 102 perpendicular to each support rod 101 are arranged below each support rod 101, and the support legs 102 are evenly spaced along the length of the corresponding support rod 101. The number of support legs 102 below each support rod 101 is 2-8. In this embodiment, three support legs 102 are arranged below each support rod 101, two of which are fixedly connected to the ends of the corresponding support rod 101, and the other support leg 102 is located at the center of the support rod 101; the top of the support leg 102 is fixedly connected to the support rod 101, and the connection between the two can be an integral connection, a bolt connection or welding. In this embodiment, the connection between the top of the support leg 102 and the support rod 101 is welding. The bottom end of the support leg 102 is provided with a universal wheel 103 to facilitate the movement of the support frame 1; the universal wheel 103 is provided with a locking plate for locking the universal wheel 103. When the mobile support frame 1 is located at the floor scale, the locking plate is rotated to lock the universal wheel 103 to prevent the support frame 1 from moving during operation.

[0022] In this embodiment, the support leg 102 is a retractable structure, and the extension and retraction process of the support leg 102 can drive the temporary grain storage hopper 2 to rise or fall, that is, the height of the temporary grain storage hopper 2 and the support rod 101 can be adjusted by adjusting the height of the support leg 102, so that the utility model can adapt to different types of grain transport vehicles.

[0023] like Figure 1As shown, the temporary grain storage hopper 2 is a funnel-shaped structure, and the large end of the temporary grain storage hopper 2 is fixedly connected to the support rod 101 , and the small end of the temporary grain storage hopper 2 is located below the support rod 101 . The bottom end of the temporary grain storage hopper 2 is provided with a grain outlet 201 for discharging grain to the grain transport vehicle. The cross-section of the grain outlet 201 is square, that is, the grain outlet 201 is a rectangular structure. The bottom end of the grain outlet 201 is rotatably provided with a valve 4 that can cut off or open the grain outlet 201. In this embodiment, the bottom end of the grain outlet 201 is an arc-shaped structure convex downward therefrom, and the valve 4 includes an arc-shaped plate for sealing the discharge end and connecting plates located on both sides of the discharge end. The connecting plates are fan-shaped structures, and the grain outlet 201 is rotatably connected to the connecting plates through a rotating shaft 401.

Both ends of the rotating shaft 401 are rotatably connected to the support frame 1 through connecting blocks 402, and the support frame 1 is provided with a driving motor for driving the rotating shaft 401 to rotate reciprocally. When the grain truck drives onto the weighing scale, if the weight of the grain loaded on the grain truck is lower than the target value, turn the valve 4 to allow the grain in the temporary storage hopper 2 to flow into the grain truck through the grain outlet 201 until the weight of the grain loaded on the grain truck reaches the target value; then, turn the valve 4 in the opposite direction to block the grain outlet 201.

[0024] In other embodiments of the utility model, an electric gate is used to replace the valve 4. When the grain outlet 201 of the temporary grain storage hopper needs to release grain, the motor on the gate is directly started, the gate is opened to release the grain, and the gate is closed when the grain truck reaches the target loading value.

[0025] A hose auger 5 is arranged on the edge of the temporary grain storage hopper 2, and one end of the hose auger 5 has a feeding head 502 that can be extended into the grain transport vehicle. The main body of the hose auger 5 is fixed on the edge of the temporary grain storage hopper 2, and the outlet of the discharge end 501 thereof is facing the temporary grain storage hopper. A driving unit for driving the feeding head 502 to move up and down is arranged on the support frame 1, and the driving unit includes a driving rod 601 and a driving cylinder 6. The bottom end of the driving rod 601 is fixedly connected to the feeding head 502, and the other end of the driving rod 601 is drivingly connected to the driving cylinder 6. Specifically, the driving rod 601 is coaxially fixedly connected with the piston of the driving cylinder 6, and the piston of the driving cylinder 6 drives the driving rod 601 to reciprocate up and down, thereby driving the feeding head 502 to reciprocate up and down. When the grain truck drives to the ground scale, if the weight of the grain loaded on the grain truck is higher than the target value, the feeding head 502 of the hose auger 5 is lowered and extended into the grain in the grain truck, and the grain in the grain truck is drawn into the temporary grain storage hopper 2, so that the weight of the grain in the grain truck can be accurately controlled, and the grain truck can be prevented from traveling back and forth in the grain warehouse, while saving time and reducing costs.

[0026] The above is a basic implementation method of the utility model, which can be further improved, optimized and limited on the basis of the above to obtain the following embodiments:

[0027] Example 2

[0028] This embodiment is an improved solution of a device for adding and subtracting loads of a grain transport vehicle out of a warehouse, which is made on the basis of the embodiment 1. Its main structure is the same as that of the embodiment 1, and the improvement lies in that a plurality of reinforcing rods are arranged between the two support rods 101 and are spaced apart along the extension direction thereof. The reinforcing rod is vertically connected to the support rods 101, one end of the reinforcing rod is connected to one of the support rods 101, and the other end of the reinforcing rod is connected to another support rod 101.

One end of the elastic rope 7 is fixedly connected to the support frame 1, and the other end of the elastic rope 7 is fixedly connected to the hose auger 5, so that the part of the hose auger 5 located below the support frame 1 is arc-shaped. Since the discharge end 501 needs to move up and down reciprocatingly, in order to avoid irregular bending of the hose auger 5 and damage to the hose auger 5, the part located below the support rod 101 is in a bent state. When the driving rod 601 drives the material taking head 502 to move downward, the hose auger 5 is straightened, and when the driving rod 601 drives the material taking head 502 to move upward, the hose auger 5 bends; the elastic rope 7 is fixed at the center position of the hose auger 5. When the driving rod 601 drives the material taking head 502 to move upward, the elastic rope 7 pulls the center part to move to the upper left, so that the hose auger 5 is arc-shaped.

[0031] If the elastic rope 7 is directly tied to the hose auger 5 , the hose auger 5 will be pulled to deform. Therefore, a mounting ring 701 is sleeved on the hose auger 5 . The mounting ring 701 is made of hard material, and the elastic rope 7 is fixedly connected to the mounting ring 701 .
