Technical Field

[0001] The utility model relates to the technical field of lower hoppers, in particular to a folding sensor device for lower hoppers. Background Art

[0002] Pressure sensor is the most commonly used sensor in industrial practice. It is a device or apparatus that can sense pressure signals and convert pressure signals into usable output electrical signals according to certain rules. It is widely used in various industrial automatic control environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automatic control, aerospace, military industry, petrochemical, oil wells, electric power, ships, machine tools, pipelines and many other industries.

[0003] Most of the existing material hoppers are fixed pipe structures, which may be blocked during material discharge. Material blockage will reduce the loading speed. The fixed structure needs to stop the material delivery when it is blocked. At this time, the material hopper needs to be manually unblocked, which is difficult to operate. At this time, a pressure sensor can be used to detect whether the material discharge pipe is in an unobstructed state.

[0004] Therefore, we propose a folding sensor device for the lower hopper to solve the above problems. Utility Model Content

[0005] The utility model provides a folding sensor device for a lower hopper, which solves the problem mentioned in the above background technology that most of the existing lower hoppers are fixed pipeline structures, which may be blocked when unloading materials.

[0012] The utility model has the following beneficial effects:

[0013] 1. Pour the material to be transported into the hopper body. When unloading, the connecting pipe assembly may be blocked.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] See also Figure 1-Figure 3 A folding sensor device for a lower hopper comprises a lower hopper body 1 and supporting legs 2 fixedly mounted on the four sides of the lower end of the lower hopper body 1, a connecting pipe assembly 3 is installed at the lower end of the lower hopper body 1, the connecting pipe assembly 3 comprises connecting plates 31 fixedly mounted on both sides of the lower end of the lower hopper body 1, movable plates 32 are movably mounted on both sides of the connecting plate 31, an electric push rod 33 is fixedly mounted between the connecting plate 31 and the movable plate 32, an air bag 34 is fixedly mounted on the movable plate 32, a pressure sensor 35 is installed in the air bag 34, and an anti-blocking assembly 5 is installed between the two connecting plates 31.

[0023] When the device is used for unloading, the material to be transported is poured into the lower hopper body 1 from the upper opening of the unloading hopper body 1. When unloading, the connecting pipe assembly 3 may be blocked due to the material unloading being too fast. At this time, the material piles up and squeezes the airbags 34 on the side walls of the movable plates 32 on both sides. When the airbags 34 are squeezed, they are deformed and contact the pressure sensors 35 in the airbags 34. The pressure sensors 35 are squeezed at this time and transmit the signals to the outside for display. At this time, the electric push rods 33 can be started. The electric push rods 33 are started to push the movable plates 32 on both sides outward. At this time, the area formed between the connecting plate 31 and the movable plate 32 is increased, and the blocked material can fall downward from the connecting plate 31 and the movable plate 32. The folding sensor device of the unloading hopper can expand the area of ​​the unloading port when the unloading hopper is blocked, which is more convenient for the material to be discharged. The unloading speed can also be adjusted by adjusting the distance of the movable plates 32.

[0024] Example 2

[0025] See also Figure 2-Figure 4 The anti-blocking component 5 includes a motor 51 fixedly installed in one of the supporting legs 2, and a rotating rod 52 is fixedly installed at the output end of the motor 51. With the cooperation between the supporting leg 2, the motor 51 and the rotating rod 52, the motor 51 is fixedly installed on the supporting leg 2.

[0026] A plurality of fixed rods 53 are equidistantly fixedly mounted on the rotating rod 52, and a plurality of stirring rods 54 are fixedly mounted on the side walls of the fixed rods 53. With the cooperation between the rotating rod 52, the fixed rods 53 and the stirring rods 54, the rotation of the stirring rods 54 can drive the movement of the material and stir the material.

[0027] A telescopic baffle 4 is fixedly mounted on the lower ends of the connecting plate 31 and the movable plate 32 , and the telescopic baffle 4 can reduce dust.

[0028] A display light 21 is fixedly installed on the side wall of one of the supporting legs 2, and a control switch 22 is fixedly installed on the lower end of the display light 21. With the cooperation between the supporting leg 2, the display light 21 and the control switch 22, the display light 21 can intuitively display whether the inside of the connecting pipe assembly 3 is in a flow state.

[0029] The display light 21 is electrically connected to the pressure sensor 35 , and the control switch 22 is electrically connected to the electric push rod 33 and the motor 51 , respectively. When the pressure sensor 35 is squeezed, the display light 21 lights up.

[0030] When the material is conveyed, the material is poured in through the upper opening of the lower hopper body 1. When the connection pipe assembly 3 is blocked during material conveying, a large amount of material is accumulated between the connecting plate 31 and the movable plate 32. When the material is accumulated, the pressure sensors 35 in the air bags 34 on both sides are squeezed. At this time, the pressure sensor 35 transmits a signal to the display light 21 on the side wall of the supporting leg 2. At this time, the display light 21 lights up. When the display light 21 corresponding to the pressure sensor 35 lights up, the electric push rod 33 and the motor 51 can be started by the control switch 22. The electric push rod 33 is started to make the connecting plate 31 and the movable plate 3 2 becomes larger, and the material is easy to move downward. When the motor 51 is started, the output end drives the rotating rod 52 to rotate. When the rotating rod 52 rotates, it drives the fixed rod 53 and the stirring rod 54 fixed to its side wall to rotate, so as to stir the material, making it easier for the material to move downward. When the movable plate 32 moves, the telescopic baffle 4 is stretched at the same time, which can reduce the outflow of dust. When the device is in use, the state inside the connecting pipe component 3 can be displayed through the display light 21 and the control switch 22. The control switch 22 can quickly make the material of the connecting pipe component 3 flow when it is blocked, which is convenient for the unloading of the hopper body 1. The operation is simple and the display is more intuitive.
