Description

Technical Field

[0001] This utility model relates to the field of weighbridge replenishment technology, specifically to an automatic weighbridge replenishment device. Background Technology

[0002] Mineral products are transported by road, and two weighbridges are installed for weighing. This mode of transport dictates that we must precisely control the weight loaded on each vehicle. Overloading is not permitted on the road, while underloading increases transportation costs and reduces economic efficiency.

[0003] However, loading points in mines are highly dispersed, and the diverse loading equipment makes it impossible to accurately control the load weight during loading. Prior to this technology, a method was used where materials were weighed once, then returned to the original loading point for replenishment due to non-standard weighing.

[0004] This approach has the following problems:

[0005] 1. There is a high probability that the weighbridge will be used for weighing two or even three times, resulting in low utilization of the weighbridge.

[0006] 2. Weighbridges are frequently damaged due to vehicles reversing.

[0007] 3. The road before the weighbridge is not smooth, and congestion is often caused by vehicles reversing and going back to refill materials;

[0008] 4. Increased vehicle operating time, increased energy consumption, and increased labor costs for loading and unloading result in high transportation costs. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides an automatic weighbridge replenishment device. This device solves the problem that most mine loading points are very scattered and the loading equipment is diverse, making it impossible to accurately control the loading weight during loading. As a result, after a single weighing, if the weight is not up to standard, the vehicle needs to return to the original loading point for replenishment and weigh the material multiple times. This not only leads to low weighbridge utilization but also causes vehicle congestion at the weighbridge.

[0010] To achieve the above objectives, this utility model is implemented through the following technical solution: an automatic material replenishment device for a weighbridge includes a material distributing funnel, a support spring assembly and a limit switch assembly are provided at the bottom of the material distributing funnel, the limit switch assembly is provided on one side of the support spring assembly, floating material replenishment funnels are respectively provided on both sides below the material distributing funnel, the floating material replenishment funnels are fixedly connected to the support spring assembly, and an automatic door closing linkage mechanism is provided on one side of the floating material replenishment funnel.

[0011] Preferably, the material distribution funnel has discharge ports on both sides, and the discharge ports on both sides lead to their respective floating replenishment funnels.

[0012] Preferably, a movable door panel is movably installed on the outer side of the discharge port, and the movable door panel is connected to the floating side of the floating feeding funnel through an automatic door closing linkage mechanism.

[0013] Preferably, a conveyor belt is provided on one side of the material distribution funnel, and one end of the conveyor belt is located at the upper opening of the material distribution funnel.

[0014] Preferably, a storage bin is provided above the other end of the conveyor belt, and the material in the storage bin is conveyed to the distribution funnel by the conveyor belt.

[0015] Preferably, a support is provided below the material distributing funnel, the support spring assembly and the limit switch assembly are disposed on the support, the material distributing funnel is fixedly connected to the support, and the floating material replenishing funnel is slidably connected to the support.

[0016] Preferably, the floating feeding funnel is movably connected to the limit switch assembly.

[0017] Preferably, the lower opening of the floating feeding funnel is equipped with a feeding electric gate, which is used to control the opening and closing of the floating feeding funnel.

[0018] This utility model discloses an automatic material replenishment device for weighbridges, which has the following beneficial effects:

[0019] This automatic material replenishment device for the weighbridge is equipped with a material distribution funnel and a floating material replenishment funnel. The material in the distribution funnel enters the floating material replenishment funnels on both sides, causing the floating material replenishment funnels to move downwards. This, in turn, compresses the support spring assembly. Through the coordinated use of the limit switch assembly and the automatic door closing linkage mechanism, both floating material replenishment funnels are filled with material. When a vehicle needs to be replenished, the weighbridge operator opens the electric replenishment gate to allow the material to enter the cargo box. When the expected weight is reached, the electric replenishment gate is closed, completing the accurate loading. This avoids the problem of having to go back to the original loading point to reload after a non-standard weighing, which not only results in low weighbridge utilization but also easily causes vehicle congestion at the weighbridge.

[0029] Furthermore, a storage bin 1 is provided above the other end of the conveyor belt 2, and the material in the storage bin 1 is conveyed to the distribution funnel 3 by the conveyor belt 2.

[0030] Example 2

[0031] According to the appendix Figure 1-2 As shown, the device includes a material distribution funnel 3. The bottom of the material distribution funnel 3 is provided with a support spring assembly 4 and a limit switch assembly 6. The limit switch assembly 6 is located on one side of the support spring assembly 4. Floating material replenishing funnels 7 are respectively provided on both sides below the material distribution funnel 3. The floating material replenishing funnels 7 are fixedly connected to the support spring assembly 4. An automatic door closing linkage mechanism 5 is provided on one side of the floating material replenishing funnel 7.

[0032] Furthermore, discharge ports are provided on both sides of the material distribution funnel 3, and the discharge ports on both sides lead to their respective floating feeding funnels 7.

[0033] Furthermore, a movable door panel is movably installed on the outside of the discharge port, and the movable door panel is connected to the floating side of the floating feeding hopper 7 through the automatic door closing linkage mechanism 5.

[0034] Furthermore, a support is provided below the material distribution funnel 3, and the support spring assembly 4 and the limit switch assembly 6 are set on the support. The material distribution funnel 3 is fixedly connected to the support, and the floating material replenishment funnel 7 is slidably connected to the support.

[0035] Furthermore, the floating feed hopper 7 is movably connected to the limit switch group 6.

[0036] Furthermore, a feeding electric gate 8 is installed at the lower opening of the floating feeding hopper 7. The feeding electric gate 8 is used to control the opening and closing of the floating feeding hopper 7. The material in the distribution hopper 3 enters the floating feeding hoppers 7 on both sides, causing the floating feeding hoppers 7 to move downwards. This causes the support spring assembly 4 to be compressed. Through the cooperation of the limit switch assembly 6 and the automatic door closing linkage mechanism 5, both floating feeding hoppers 7 are filled with material. When the vehicle needs to be reloaded, the weighbridge operator opens the feeding electric gate 8 to allow the material to enter the cargo box. When the expected weight is reached, the feeding electric gate 8 is closed to complete the accurate loading. This avoids the problem of having to go back to the original loading point to reload after a non-standard weighing, which requires multiple weighings on the weighbridge. This not only results in low weighbridge utilization but also easily causes vehicle congestion at the weighbridge.

[0037] Working Principle: Materials are pre-transported to storage silo 1. After power is turned on, conveyor belt 2 automatically operates, conveying materials to distribution hopper 3 and two floating feed hoppers 7. As materials enter, support spring assembly 4 is compressed, causing the floating feed hoppers 7 to move downwards. At this time, the two floating feed hoppers 7 do not necessarily move downwards synchronously. When one of the floating feed hoppers 7 reaches the lower limit switch corresponding to limit switch assembly 6, the corresponding switch opens. Conveyor belt 2 does not stop material from continuing to enter the floating feed hopper 7; the floating feed hopper 7 continues to descend, driving the automatic door closing linkage mechanism 5 to flip, thereby closing the corresponding movable door plate on distribution hopper 3. Material no longer enters the corresponding floating feed hopper 7, but can only enter the other floating feed hopper 7 with a slower feeding speed. As the other floating feed hopper 7 descends, it triggers limit switch assembly 6, opening the corresponding lower limit switch, and conveyor belt 2 stops. At this point, both floating feed hoppers 7 are full of material.

[0038] When a vehicle is on the weighbridge, its cargo box is directly below the floating feeding hopper 7. When the vehicle needs to be refilled, the weighbridge operator opens the feeding electric gate 8 to allow the material to enter the cargo box. When the expected weight is reached, the feeding electric gate 8 is closed, completing the precise loading and direct invoicing and shipment from the mine.

[0039] As the vehicle continuously replenishes material, the material in the floating feeding hopper 7 decreases. Under the action of the support spring group 4, the floating feeding hopper 7 moves upward, driving the automatic door closing linkage mechanism 5 to flip upward, causing the corresponding movable door plate on the distributing hopper 3 to open. It continues to move upward, causing the lower limit switch of the corresponding limit switch group 6 to reset. At this time, the conveyor belt 2 cannot start. When the material in any floating feeding hopper 7 decreases to almost empty, the upper limit switch of the limit switch group 6 closes, and the conveyor belt 2 starts automatically, adding material to the floating feeding hopper 7 until both floating feeding hoppers 7 are full. Then the conveyor belt 2 stops, and so on in an automatic cycle.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
