Description

Technical Field

[0001] The utility model belongs to the technical field of belt scales, in particular to an electronic belt scale. Background Art

[0002] An electronic belt scale is an automatic weighing device that continuously weighs bulk materials on a conveyor belt without the need to subdivide the mass or interrupt the movement of the conveyor belt. It is generally installed on a conveyor frame and is widely used in coal mining.

[0003] Coal has less adhesion when it is drier. Within a certain range, the adhesion of coal increases with the increase of moisture. When the coal is relatively wet, the coal dust in the raw coal is easy to adhere to the belt scale. If these adhered coal dust are not cleaned in time, it will affect the normal operation of the equipment and affect the measurement accuracy and service life of the equipment. In order to avoid errors, the coal dust adhered to the belt scale needs to be cleaned. Secondly, wet coal will leave water stains on the conveyor belt. If not handled in time, the conveyor belt will aggravate the subsequent damp adhesion of coal during use, affecting its use.

[0026] In order to enable those skilled in the art to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0027] As Figures 1 to 5 shown, the electronic belt scale in an embodiment of the present utility model includes a belt scale body 1, on which a driving shaft 101 and a conveyor belt 102 are respectively installed, and the conveyor belt 102 is rotatably connected to the driving shaft 101. A driving device 103 is fixedly connected to the belt scale body 1, and the output end of the driving device 103 is fixedly connected to one end of the driving shaft 101. Specifically, the driving device 103 is a driving motor, and by using the driving motor to provide power, the driving shaft 101 can be driven to rotate, and then the conveyor belt 102 above it can be operated to convey materials such as coal and minerals.

[0028] Among them, a weighing assembly 104 is fixedly connected to the belt scale body 1, so that the materials can be weighed and measured during the conveying process. A discharge hopper 105 is fixedly connected to the belt scale body 1, and the discharge hopper 105 is arranged at the output part of the conveyor belt 102 to facilitate the outward output of the materials.

[0029] As Figure 3 shown, in order to facilitate the cleaning of the conveyor belt 102, a first pulley 2 is fixedly connected to the drive shaft 101, a brush roller 3 is rotatably connected to the belt scale body 1, a second pulley 11 is fixedly connected to the brush roller 3, and the second pulley 11 is drivingly connected to the first pulley 2 through a first belt 18. By using its transmission cooperation, the brush roller 3 can be driven to rotate. While rotating, the bristles on the brush roller 3 can contact the conveyor belt 102, so as to sweep the coal dust adhering to the conveyor belt 102.

[0030] As Figure 1 、 Figure 2 and Figure 4 shown, in order to collect the swept coal dust, a receiving box 16 is placed on one side of the belt scale body 1, and an inclined plate 4 is fixedly connected to the belt scale body 1. The inclined plate 4 is located outside the brush roller 3 and above the receiving box 16. The provided inclined plate 4 can guide the swept coal dust, so that it can better enter the receiving box 16 for storage.

[0031] As Figure 4 shown, in order to facilitate the subsequent recycling of the collected coal dust, a grid plate 17 is fixedly connected inside the receiving box 16, and the collected coal dust is stored on the grid plate 17. A housing 13 is fixedly connected to the belt scale body 1, a driving device 103 is located inside the housing 13, a blower 14 is fixedly connected to the housing 13, a conveying pipe 15 is fixedly connected and communicated to the housing 13, and the other end of the conveying pipe 15 is fixedly connected and communicated to the receiving box 16. Specifically, when the driving device 103 is operating, a large amount of heat will be generated. The housing 13 can play a role in concentrating the heat. By using the cooperation of the blower 14 and the conveying pipe 15, an air flow can be generated to blow the heat to the lower part of the grid plate 17 inside the receiving box 16 to dry the collected wet coal dust. It should be noted that during the blowing process, the heat of the driving device 103 can be taken away to play a role in heat dissipation. Therefore, the driving device 103 can operate continuously and reliably.

[0032] As Figure 3 shown, a connecting shaft 5 is rotatably connected to the belt scale body 1, and a wiping roller 6 is movably installed on the connecting shaft 5. The wiping roller 6 can dry the water stains on the surface of the conveyor belt 102. Specifically, there are two connecting shafts 5, which are respectively fixed on the brackets on both sides of the belt scale body 1. Both ends of the wiping roller 6 have grooves, and it can be directly inserted into the connecting shaft 5 during installation, which is more convenient. And the wiping roller 6 is in continuous contact with the conveyor belt 102 during use. Driven by the conveyor belt 102, the wiping roller 6 can rotate to enhance its use effect.

[0033] As Figure 5As shown, two springs 10 are fixedly connected to the belt scale body 1. The other ends of the two springs 10 are commonly fixedly connected to a pressing plate 9, and the upper end surface of the pressing plate 9 is in contact with the wiping roller 6. A rotating shaft 7 is rotatably connected to the belt scale body 1. The rotating shaft 7 is located below the pressing plate 9, and multiple groups of cams 8 are fixedly connected to the rotating shaft 7. A third pulley 12 is fixedly connected to the rotating shaft 7, and the third pulley 12 is drivingly connected to a second pulley 11 through a second belt 19. By means of the driving cooperation of the second pulley 11, the second belt 19, and the third pulley 12, the rotating shaft 7 can be driven to rotate. By means of the cams 8 on the rotating shaft 7, during its rotation, it can contact the pressing plate 9 and push the pressing plate 9 upward to squeeze the wiping roller 6 to dehydrate it, so as to ensure that it has a good wiping effect during long-term use. By means of the provided springs 10, the pressing plate 9 can be driven to reset for continuous use.

[0034] During specific use, the driving device 103 is used to drive the equipment to operate. Coal materials can be conveyed on the conveyor belt 102. During the conveying process, the weighing assembly 104 can be used to weigh it. Subsequently, the rotating brush roller 3 can clean the conveyor belt 102. The coal dust cleaned out can fall into the material receiving box 16 for storage under the guiding action of the inclined plate 4. The wiping roller 6 can dry the water stains on the conveyor belt 102. When the cam 8 rotates, it can push the pressing plate 9 upward to squeeze the wiping roller 6 to dehydrate it, so as to ensure its good use state. The heat generated by the operation of the driving device 103 can be sent into the material receiving box 16 through the conveying pipeline 15 to dry the wet coal dust.

[0035] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
