Description

Technical Field

[0001] The utility model belongs to the technical field of plate chain conveyors, in particular to a plate chain conveyor. Background Art

[0002] Conveyors are a crucial piece of equipment in automated production lines. They are the most important equipment for transporting and loading and unloading bulk materials. Chain and plate conveyors are the most common type of conveyor.

[0003] For example, the Chinese patent with announcement number CN217995761 U discloses a chain conveyor, which relates to the field of conveyor technology, including a box body and a base, one side of the box body is fixedly connected to a second motor, the output end of the second motor is fixedly connected to a first rotating shaft, one end of the first rotating shaft is fixedly connected to a first pulley, the internal rotation of the box body is connected to a second rotating shaft, one end of the second rotating shaft is fixedly connected to a second pulley, and the second pulley is connected to the first pulley through a belt transmission. The beneficial effect of the utility model is: the second motor is set up, which can drive the first pulley to rotate, and the second rotating shaft can be driven to rotate under the transmission action of the belt, and then the meshing connection between the first bevel gear and the second bevel gear makes the third rotating shaft and the cleaning brush at one end rotate to clean the dirt on the surface of the chain plate body, thereby improving the functionality of the device and reducing the labor of the staff.

[0004] The above patent has the following problems:

[0005] This patent has some shortcomings when in use. For example, the device generates some dust when cleaning the dirt on the surface of the chain plate body. The device is not convenient for collecting the dust, which causes the dust to float in the work area and workers to inhale the dust while working, affecting their health. At the same time, when the chain plate body is conveying materials, the materials are prone to deviation, which can cause the materials to fall from the chain plate body to the outside and easily cause damage to the materials. In view of this, we propose a plate chain conveyor. Utility Model Content

[0006] The purpose of the present utility model is to provide a plate chain conveyor to solve the problems raised in the above background technology.

[0007] In view of this, the utility model provides a plate chain conveyor, comprising:

[0008] A U-shaped frame, wherein a U-shaped plate is symmetrically fixedly installed on the top of the U-shaped frame, a plurality of rollers are rotatably installed in the U-shaped plate, two sprockets 1 and two sprockets 2 are rotatably installed on both sides of the inner wall of the U-shaped frame, a connecting rod 1 and a connecting rod 2 are fixedly installed between the two sprockets 1 and the two sprockets 2 respectively, a chain 1 is installed for transmission between one of the sprockets 1 and one of the sprockets 2, a chain 2 is installed for transmission between the other sprocket 1 and the other sprocket 2, and a plurality of chain plate bodies are fixedly installed between the chain 1 and the chain 2;

[0009] The dust box is fixedly installed in the U-shaped frame and is located below the chain plate body. A U-shaped tube is fixedly installed on one side of the U-shaped frame. Both ends of the U-shaped tube pass through one side of the U-shaped frame and one side of the dust box and are fixedly installed with fixed tubes. A cleaning rod is rotatably installed in the dust box and between the two fixed tubes. A plurality of air inlet pipes are fixedly installed on the top of the fixed tube. An exhaust fan is fixedly installed on one side of the U-shaped tube. A fixed box is fixedly installed on the air outlet end of the exhaust fan. A dust filter is plugged into the fixed box. A collection box is plugged into the dust box and located below the cleaning rod.

[0010] A drive assembly is located on the U-shaped frame and is used to drive one of the sprockets to rotate and the cleaning rod to rotate.

[0011] In this technical solution, a driving assembly is set up to drive one of the sprockets to rotate, and then one of the sprockets will drive the connecting rod to rotate, and the connecting rod will drive the other sprocket to rotate, and one of the sprockets will drive the chain to transmit, thereby driving one of the sprockets to rotate. At the same time, the rotation of the other sprocket will drive the chain to transmit, so that the other sprocket will also rotate, and the connecting rod between the two sprockets will rotate. At this time, several chain plate bodies will be displaced, and then the driving assembly will also drive the cleaning rod to rotate. During the rotation of the cleaning rod, the cleaning rod will clean several chain plate bodies, thereby sweeping the dirt attached to the chain plate bodies to the dustproof The dust on the chain plate body will also be swept down in the box. The exhaust fan will be started. The dust-laden air generated by the cleaning rod when cleaning the chain plate body will enter the corresponding fixed pipes through several air inlet pipes. Then, the dust-laden air in the two fixed pipes will enter the U-shaped pipe. The dust in the U-shaped pipe will be transported to the fixed box by the exhaust fan. Then, the dust-laden air will pass through the dust filter. Under the action of the dust filter, the dust in the air can be filtered, so that the dust in the air stays on the dust filter. Then, the clean air will be discharged from the bottom of the fixed box. At the same time, some dirt and dust will be in the dust box and fall into the collection box. Clean water is placed in the collection box to absorb the dust.

[0012] When several chain plates are conveying materials, the rollers in the two U-shaped plates can act as a barrier to the materials. When the materials come into contact with the rollers, the materials will drive the rollers to rotate in the corresponding U-shaped plates, which will not affect the normal displacement of the materials and can prevent the materials from being offset and falling to the outside.

[0013] In the above technical solution, further, the driving component includes:

[0014] A motor, the motor being fixedly mounted on one side of the U-shaped frame, the output end of the motor passing through one side of the U-shaped frame and being coaxially connected to one of the sprockets;

[0016] In this technical solution, the motor is started so that the output shaft of the motor drives one of the sprockets to rotate, and then one of the sprockets will drive the connecting rod to rotate, and the connecting rod will drive the other sprocket to rotate, and one of the sprockets will drive the chain to transmit, thereby driving one of the sprockets to rotate. At the same time, the rotation of the other sprocket will drive the chain to transmit, so that the other sprocket will also rotate, and the connecting rod between the two sprockets will rotate. At this time, several chain plate bodies will be displaced, and then the other sprocket will also drive one of the transmission wheels to rotate, and one of the transmission wheels will drive the belt transmission, and the belt will drive the other transmission wheel to rotate, and then the other transmission wheel will drive the cleaning rod to rotate.

[0017] In the above technical solution, further, the output shaft of the motor is rotatably connected to one side of the U-shaped frame, and one end of the other transmission wheel is rotatably connected to the other side of the dustproof box.

[0018] In this technical solution, it is ensured that the output shaft of the motor can rotate normally; and it is ensured that one end of the transmission wheel can rotate normally.

[0019] In the above technical solution, further, the cleaning rod is in contact with the bottom of the chain plate body, and the air intake pipe is connected to the fixed pipe.

[0020] In this technical solution, it is ensured that the cleaning rod can clean the dust on the chain plate body; it is ensured that the floating air containing dust can enter the corresponding fixed pipe through the plurality of air inlet pipes.

[0021] In the above technical solution, further, the air inlet end of the exhaust fan is connected to the U-shaped tube, the air outlet end of the exhaust fan is connected to the fixed box, and the dust filter is located below the air outlet end of the exhaust fan.

[0024] In this technical solution, some dirt and dust will be in the dustproof box and fall into the collection box. Clean water is placed in the collection box to absorb the dust.

[0025] In the above technical solution, further, the fixed tube is connected to the U-shaped tube.

[0026] In this technical solution, it is ensured that the air with dust in the fixed tube can enter the U-shaped tube. The beneficial effects of this utility model are:

[0027] 1. The plate chain conveyor can play the role of enclosing materials through the U-shaped plates and rollers. When the material contacts several rollers, the material will drive the rollers to rotate in the corresponding U-shaped plates, which will not affect the normal displacement of the material.
