Description

Technical Field

[0001] The utility model belongs to the technical field of garbage trucks, and specifically relates to an automatic weighing system for garbage trucks. Background Art

[0002] Garbage trucks are mainly used for municipal sanitation and transporting various garbage in factories and mines. They are especially suitable for transporting domestic garbage in communities, and can compress and crush the loaded garbage to increase its density and reduce its volume, greatly improving the efficiency of garbage collection and transportation. New garbage trucks have the characteristics of reliable quality, low failure rate, convenient maintenance, and low operating costs.

[0003] When garbage needs to be cleared, the current method is to fill the garbage truck box with garbage to improve the efficiency of garbage transportation. However, if the weight of the garbage pile is too large, the pressure on the garbage truck box will be too large. When the garbage truck box is under too much pressure and encounters a bumpy road section during transportation, it is more likely to cause damage to the garbage truck box, and there will also be a phenomenon of garbage falling out of the garbage truck box. In view of this, the utility model particularly provides an automatic weighing system for garbage trucks to solve the above problems. Summary of the Utility Model

[0004] To solve the technical problem that if the weight of the garbage pile is too large, the pressure on the garbage truck box will be too large, and when the garbage truck box is under too much pressure and encounters a bumpy road section during transportation, it is more likely to cause damage to the garbage truck box, the basic concept of the technical solution adopted by the utility model is:

[0005] The automatic weighing system for garbage trucks includes a garbage truck box. A load-bearing plate is slidably installed inside the garbage truck box. The middle outer wall of the bottom of the load-bearing plate is fixedly connected with an installation bracket. Symmetrically arranged guide plates are hingedly installed at the bottom of the installation bracket. Symmetrically arranged sliding brackets are slidably installed on the inner wall of the bottom of the garbage truck box. The bottom ends of the two guide plates are respectively hingedly installed on the two sliding brackets. A transverse movement plate is fixedly connected to one side of each of the two sliding brackets. The two transverse movement plates both extend to the outside of the garbage truck box. A first connecting frame is fixedly connected to one end of each of the two transverse movement plates located outside the garbage truck box. Guide rods are hingedly installed on the two first connecting frames. Lifting plates are slidably installed on both sides of the garbage truck box. A second connecting frame is fixedly connected to the end position of each of the two lifting plates. The top ends of the two guide rods are respectively hingedly installed on the two second connecting frames. Symmetrically arranged limiting plates are fixedly connected to the outer walls on both sides of the garbage truck box, and the two limiting plates are respectively located directly above the two lifting plates.

[0006] As a preferred embodiment of the utility model, symmetrically arranged rectangular movable openings are formed on both sides of the garbage truck box, and the two transverse movement plates are respectively in contact with the inner walls of the two rectangular movable openings.

[0007] As a preferred embodiment of the present utility model, lifting grooves which are symmetrically arranged are formed on both sides of the garbage box, and the two lifting plates are respectively slidably connected to the inner walls of the two lifting grooves.

[0008] As a preferred embodiment of the present utility model, guide columns which are symmetrically arranged are fixedly connected to the inner walls of both sides of the bottom of the garbage box.

[0009] As a preferred embodiment of the present utility model, through holes which are symmetrically arranged are formed on both sides of the load-bearing plate, and the guide columns are slidably connected to the inner walls of the through holes.

[0010] As a preferred embodiment of the present utility model, support springs which are symmetrically arranged are fixedly connected to the inner walls of both sides of the bottom of the garbage box. The top ends of the support springs are fixedly connected to the outer wall of the bottom of the load-bearing plate, and the support springs are sleeved on the guide columns.

[0011] As a preferred embodiment of the present utility model, the mounting bracket, the sliding bracket, the first connecting frame and the second connecting frame are all of a portal structure.

[0012] The present utility model has the following beneficial effects compared with the prior art:

[0013] In the present utility model, the load-bearing plate can support the loaded garbage. When the garbage is poured onto the load-bearing plate, the load-bearing plate is pressed downwards. The load-bearing plate drives the mounting bracket to move downwards. The mounting bracket cooperates with the two sliding brackets arranged to change the inclination angles of the two guide plates. When the inclination angles of the two guide plates change, the two sliding brackets can be driven to move in opposite directions, so that the two sliding brackets drive the two transverse moving plates to move in opposite directions. The two transverse moving plates drive the two first connecting frames to move in opposite directions. The two first connecting frames cooperate with the two second connecting frames arranged to change the inclination angles of the two guide rods. When the inclination angles of the two guide rods change, the two guide rods can drive the two lifting plates to move upwards until the two lifting plates contact the outer wall of the bottom of the two limiting plates. At this time, the load-bearing plate is in a stable and immovable state, indicating that the maximum load-bearing weight of the garbage box is reached. Thus, the effect of automatic weighing can be achieved, avoiding excessive pressure on the garbage box due to the excessive weight of the garbage, playing a protective role for the garbage box, and the height of the garbage box is high enough to prevent the garbage from falling out of the garbage box when encountering a bumpy road section during transportation.

The following embodiments are used to illustrate the utility model.

[0023] like Figures 1 to 5 Shown

[0024] Automatic weighing system for garbage truck, including a garbage truck box 1. The height of the garbage truck box 1 is high enough to prevent garbage from falling out of the garbage truck box 1 when encountering bumpy roads during transportation. A load-bearing plate 2 is slidably installed inside the garbage truck box 1. The load-bearing plate 2 can support the loaded garbage. A mounting bracket 8 is fixedly connected to the outer wall of the middle part of the bottom of the load-bearing plate 2. Symmetrically arranged guide plates 9 are hingedly installed at the bottom of the mounting bracket 8. Sliding brackets 10 are symmetrically and slidably installed on the inner wall of the bottom of the garbage truck box 1. The bottom ends of the two guide plates 9 are respectively hingedly installed on the two sliding brackets 10. A transverse movement plate 11 is fixedly connected to one side of each of the two sliding brackets 10. The two transverse movement plates 11 both extend to the outside of the garbage truck box 1. A first connecting frame 12 is fixedly connected to one end of each of the two transverse movement plates 11 located outside the garbage truck box 1. Guide rods 7 are hingedly installed on the two first connecting frames 12. Lifting plates 6 are slidably installed on both sides of the garbage truck box 1. A second connecting frame 13 is fixedly connected to the end position of each of the two lifting plates 6. The top ends of the two guide rods 7 are respectively hingedly installed on the two second connecting frames 13. Symmetrically arranged limit plates 5 are fixedly connected to the outer walls on both sides of the garbage truck box 1. The two limit plates 5 are respectively located directly above the two lifting plates 6. When garbage is poured onto the load-bearing plate 2, the load-bearing plate 2 is pressed downwards. The load-bearing plate 2 drives the mounting bracket 8 to move downwards. The mounting bracket 8 cooperates with the two sliding brackets 10 to change the inclination angle of the two guide plates 9. When the inclination angle of the two guide plates 9 changes, it can drive the two sliding brackets 10 to move in opposite directions, so that the two sliding brackets 10 drive the two transverse movement plates 11 to move in opposite directions. The two transverse movement plates 11 drive the two first connecting frames 12 to move in opposite directions. The two first connecting frames 12 cooperate with the two second connecting frames 13 to change the inclination angle of the two guide rods 7. When the inclination angle of the two guide rods 7 changes, the two guide rods 7 can drive the two lifting plates 6 to move upwards until the two lifting plates 6 come into contact with the outer walls of the bottoms of the two limit plates 5. At this time, the load-bearing plate 2 is in a stable and stationary state, indicating that the maximum load capacity of the garbage truck box 1 has been reached, thus achieving the effect of automatic weighing, avoiding excessive pressure on the garbage truck box 1 due to excessive weight of the garbage, and having a protective effect on the garbage truck box 1.

[0025] In the specific implementation manner, the mounting bracket 8, the sliding bracket 10, the first connecting frame 12 and the second connecting frame 13 are all of a portal structure. Rectangular movable openings are symmetrically arranged on both sides of the garbage truck box 1. The two transverse moving plates 11 are respectively in contact with the inner walls of the two rectangular movable openings. Lifting grooves are symmetrically arranged on both sides of the garbage truck box 1. The two lifting plates 6 are respectively slidably connected to the inner walls of the two lifting grooves. Symmetrically arranged guide columns 3 are fixedly connected to the inner walls of both sides of the bottom of the garbage truck box 1. Through holes are symmetrically arranged on both sides of the bearing plate 2, and the guide columns 3 are slidably connected to the inner walls of the through holes. Symmetrically arranged support springs 4 are fixedly connected to the inner walls of both sides of the bottom of the garbage truck box 1. The top ends of the support springs 4 are fixedly connected to the outer wall of the bottom of the bearing plate 2. The support springs 4 are sleeved on the guide columns 3. After the garbage truck arrives at the destination, the door of the garbage truck box 1 is opened to unload the garbage in the garbage truck box 1. After the unloading is completed, under the action of the guide columns 3 and the support springs 4, the bearing plate 2 can be reset to the initial state, realizing the reset function of the bearing plate 2.

[0026] The implementation principle of the automatic weighing system of the garbage truck in this embodiment is as follows:

[0027] During specific use, the bearing plate 2 provided can support the loaded garbage. When the garbage is poured onto the bearing plate 2, the bearing plate 2 is pressed downward. The bearing plate 2 drives the mounting bracket 8 to move downward. The mounting bracket 8 cooperates with the two sliding brackets 10 to change the inclination angles of the two guide plates 9. When the inclination angles of the two guide plates 9 change, it can drive the two sliding brackets 10 to move in opposite directions, so that the two sliding brackets 10 drive the two transverse moving plates 11 to move in opposite directions. The two transverse moving plates 11 drive the two first connecting frames 12 to move in opposite directions. The two first connecting frames 12 cooperate with the two second connecting frames 13 to change the inclination angles of the two guide rods 7. When the inclination angles of the two guide rods 7 change, the two guide rods 7 can drive the two lifting plates 6 to move upward until the two lifting plates 6 are in contact with the outer walls of the bottoms of the two limiting plates 5. At this time, the bearing plate 2 is in a stable and immovable state, indicating that the maximum load capacity of the garbage truck box 1 is reached, so that the effect of automatic weighing can be achieved, avoiding excessive pressure on the garbage truck box 1 due to excessive weight of the garbage, playing a protective role for the garbage truck box 1, and the height of the garbage truck box 1 is high enough to prevent the garbage from falling out of the garbage truck box 1 when encountering a bumpy road during transportation. After the garbage truck arrives at the destination, the door of the garbage truck box 1 is opened to unload the garbage in the garbage truck box 1. After the unloading is completed, under the action of the guide columns 3 and the support springs 4, the bearing plate 2 can be reset to the initial state, realizing the reset function of the bearing plate 2.
