Description

TECHNICAL FIELD

[0002] Material guide groove mainly refers to the device that material is guided to the center position of belt conveyor. In common parlance, when using belt conveyor to convey material, material is guided into belt, then material guide groove plays an important role, if there is no support of material guide groove when belt conveyor conveys material, material will flow from side, and it is easy to cause noise and environmental pollution. And the existence of material guide groove can effectively shield the loss of material side, thereby reducing noise and environmental pollution.

[0003] In prior art, the announcement number CN221915944U discloses a sealing material guide groove for belt conveyor, which comprises an upper baffle, a group of side baffles are fixedly connected to the bottom surface of the upper baffle, notches are formed in the bottom surfaces of the two side baffles, first rotating rods are rotatably connected inside the two notches, anti-overflow aprons are fixedly connected to the surfaces of the two first rotating rods, a plurality of recesses are arranged at the corners of the two anti-overflow aprons, and a plurality of rolling balls are rotatably connected inside the recesses. The utility model discloses a groove is formed in the bottom end of the side baffle, and a rotating rod is rotatably connected inside the groove. An anti-overflow apron is arranged on the surface of the rotating rod, and a plurality of rolling balls are arranged at the corners of the anti-overflow apron in contact with the conveyor belt. When the conveyor belt rolls, the rolling balls will rotate with the rolling of the conveyor belt, thereby avoiding the friction between the anti-overflow apron and the conveyor belt. At the same time, the utility model also avoids the overflow of the material from the conveyor belt during the unloading of the material.

[0004] However, the above prior art still has some deficiencies in use. First, the above prior art reduces the friction loss by arranging a plurality of rolling balls at the corners of the anti-overflow apron in contact with the conveyor belt. However, the arrangement of the rolling balls will cause a gap between the anti-overflow apron and the conveyor belt, so that the material can still overflow from the gap during the falling or transportation of the material. Second, the conveyor belt will vibrate or shake during the falling of the material through the feeding port onto the conveyor belt or the transportation of the material. The vibration or shaking will also cause a gap between the conveyor belt and the anti-overflow apron. However, the structure of the above prior art does not solve this problem, and the material can still overflow, so that the sealing effect is low. Therefore, further improvement is still needed.

Further, through the arrangement of the first rubber block 31, the spring 32 and the second rubber block 33, the swing of the first connecting rod 29 can be damped and buffered, and the vibration of the belt 10 is further buffered and reduced. (The rubber block has good softness and plasticity. When subjected to vibration, the rubber molecular chain will deform, and the vibration energy will be absorbed through the friction between molecules to reduce the amplitude and frequency of vibration, that is, the role of damper. In combination with the spring 32, the damping effect can be achieved.) In the normal state of the spring 32, the first connecting rod 29 is in a horizontal state and in contact with the bottom of the belt 10. The rubber roller 30 can also limit the deformation amount of the belt 10 that is pressed down, so as to prevent the deformation amount of the belt 10 that is pressed down from being too large, causing the first connecting rod 29 to swing too much and be damaged, and improving the service life of the device.
