[0027] Example 1: Please refer to Figures 1 to 6 :

[0028] The utility model proposes a belt regulating station protection device, comprising: a conveyor frame 1;

[0029] A conveyor belt 2 is installed on the outer side of the roller on the conveyor frame 1. The conveyor frame 1 is used to support the roller on the conveyor and fix the adjustment guide rail 3 and the maintenance ladder 5 below. The conveyor belt 2 is used to transport materials; two adjustment guide rails 3 are welded at the bottom of the conveyor frame 1. The adjustment guide rails 3 are used to fix the No. 1 baffle 4, and the adjustment guide rails 3 can also support the sliding of the material cleaning block 8, so the tensioning roller 9 can slide up and down for adjustment, so that the conveyor belt 2 can be pulled downward by the tensioning roller 9 to make it in a taut state, thereby avoiding the conveyor belt 2 from being loose and ensuring the normal transportation of materials; a No. 1 baffle 4 is welded on the left and right sides of the two adjustment guide rails 3, and the No. 1 baffle 4 is matched with the No. 2 baffle 6 The combination can shield the materials and dust remaining on the conveyor belt 2, so that these materials and dust can only fall in the cavity inside the No. 1 baffle 4 and the No. 2 baffle 6, and will not fall outward; two maintenance ladders 5 are welded on the front and rear sides of the bottom of the conveyor frame 1, and the maintenance ladder 5 is used to support the No. 2 baffle 6, and when the device needs to be repaired, the top can be climbed to the top through the maintenance ladder; a total of six No. 2 baffles 6 are slidably installed between the two maintenance ladders 5. When using the device, the No. 2 baffle 6 can be installed in the rectangular opening on the maintenance ladder 5. After installation, the No. 2 baffle 6 can be tightly attached to the No. 1 baffle 4, so that it can cooperate with the No. 1 baffle 4 to form a vertical rectangular cavity, so that the materials remaining on the conveyor belt 2 can be The materials and dust can only fall in the cavity inside the No. 1 baffle plate 4 and the No. 2 baffle plate 6, and will not fall outward; a lower protective baffle plate 7 is welded between the two adjusting guide rails 3. When the conveying belt 1 breaks, the tensioning roller 9 and the material cleaning block 8 will fall rapidly due to gravity. At this time, the lower protective baffle plate 7 can resist the tensioning roller 9 and the material cleaning block 8. At the same time, the thick rubber pad on the top of the lower protective baffle plate 7 can play a buffering role to prevent the tensioning roller 9 from falling outward and causing harm to nearby personnel; a material cleaning block 8 is also slidably installed between the two adjusting guide rails 3, and the material cleaning block 8 can counterweight the tensioning roller 9, thereby increasing the gravity on the tensioning roller 9, so that it can pass The tensioning roller 9 pulls the conveyor belt 2 downward to make it in a taut state, thereby preventing the conveyor belt 2 from becoming loose and ensuring normal transportation of materials. In addition, during the rotation of the conveyor belt 2, the materials and dust remaining on it will also fall on the top of the material cleaning block 8. At the same time, the blade-like structures on the top of the left and right sides of the material cleaning block 8 can also clean the surface of the conveyor belt 2. Because the top of the material cleaning block 8 is an inclined surface, the materials on the top of the material cleaning block 8 will slide forward and backward and fall downward; a tensioning roller 9 is rotatably installed at the bottom of the material cleaning block 8. When the tensioning roller 9 slides down, the conveyor belt 2 can be pulled downward to make it in a taut state, thereby preventing the conveyor belt 2 from becoming loose and ensuring normal transportation of materials.

[0030] In the present disclosure, Figure 1-Figure 3 As shown, three rectangular openings are provided on both sides of the maintenance ladder 5, and the vertical cross-sectional dimensions of the rectangular openings are equal to the vertical cross-sectional dimensions of the second baffle 6. When using the present device, the second baffle 6 can be installed in the rectangular openings on the maintenance ladder 5, and the second baffle 6 can be removed when it is necessary to clean the materials and dust fallen from the bottom of the device or to repair the device.

[0031] In the present disclosure, Figure 2-Figure 6 As shown, a vertical strip groove is provided on one side of the adjustment guide rail 3, and a rectangular block is provided on the front and rear sides of the material cleaning block 8, and the rectangular blocks on the front and rear sides of the material cleaning block 8 can slide up and down in the vertical strip grooves on one side of the two adjustment guide rails 3. The adjustment guide rail 3 can support the sliding of the material cleaning block 8, so the tensioning roller 9 can slide up and down for adjustment, so that the conveying belt 2 can be pulled downward by the tensioning roller 9 to make it in a taut state, thereby avoiding the loosening of the conveying belt 2 and ensuring the normal transportation of materials.

[0032] In the present disclosure, Figure 1 and Figure 4 As shown, after the No. 2 baffle plate 6 is installed, its front and rear ends will be respectively located in the rectangular openings on one side of the two maintenance ladders 5, and the front and rear ends of the No. 2 baffle plate 6 are also wrapped with a layer of rubber on the outside, and the outer wall of the No. 2 baffle plate 6 will be tightly attached to the outer wall of one side of the No. 1 baffle plate 4. When using the present device, the No. 2 baffle plate 6 can be installed in the rectangular opening on the maintenance ladder 5. After the No. 2 baffle plate 6 is installed, it can be tightly attached to the No. 1 baffle plate 4, so that it can cooperate with the No. 1 baffle plate 4 to form a vertical rectangular cavity, so that the residual materials and dust on the conveyor belt 2 can be shielded, and these materials and dust can only fall in the cavity inside the No. 1 baffle plate 4 and the No. 2 baffle plate 6, and will not fall outward. The rubber on the outside of the front and rear ends of the No. 2 baffle plate 6 can increase the friction and prevent them from falling off outward.

[0033] In the present disclosure, Figure 5 and Figure 6 As shown, a circular hole is provided below the rectangular blocks on the front and rear sides of the material cleaning block 8, and the rotating shafts at the front and rear ends of the tensioning roller 9 can rotate in the circular holes below the rectangular blocks on the front and rear sides of the material cleaning block 8, so that the conveyor belt 2 can rotate normally on the outside of the tensioning roller 9.

[0034] In the present disclosure, Figure 4 and Figure 5As shown, the material cleaning blocks 8 are solid metal wedge blocks. The left and right sides of the material cleaning blocks 8 are in contact with the outer wall of the conveyor belt 2, and the left and right tops of the material cleaning blocks 8 are both blade-like structures. The material cleaning blocks 8 can counterweight the tensioning roller 9, thereby increasing the gravity exerted on the tensioning roller 9. In this way, the conveyor belt 2 can be pulled downward by the tensioning roller 9 to be in a taut state, thereby avoiding the conveyor belt 2 from being loose and ensuring normal material transportation. In addition, during the rotation of the conveyor belt 2, the residual materials and dust on it will also fall on the top of the material cleaning block 8. At the same time, the blade-like structures on the left and right tops of the material cleaning block 8 can also clean the surface of the conveyor belt 2.

[0035] Embodiment 2, based on embodiment 1, as Figure 1-Figure 6 As shown, the lower protective baffle 7 is located below the vertical strip groove on one side of the adjusting guide rail 3, and a thick rubber pad is fixed on the top of the lower protective baffle 7, and the tensioning roller 9 can contact with the thick rubber pad on the top of the lower protective baffle 7 when it slides down. When the conveyor belt 1 breaks, the tensioning roller 9 and the material cleaning block 8 will fall rapidly due to gravity. At this time, the lower protective baffle 7 can resist the tensioning roller 9 and the material cleaning block 8. At the same time, the thick rubber pad on the top of the lower protective baffle 7 can play a buffering role to prevent the tensioning roller 9 from falling outward and causing harm to nearby personnel.

[0036] The working principle of this embodiment is as follows: during installation, the conveyor belt 2 is first installed on the outer side of the rotating roller on the conveyor frame 1 and the outer side of the tensioning roller 9. When using this device, the second baffle plate 6 can be installed in the rectangular opening on the maintenance ladder 5. After installation, the second baffle plate 6 can be tightly attached to the first baffle plate 4, so that it can cooperate with the first baffle plate 4 to form a vertical rectangular cavity. During the operation of the conveyor, the material cleaning block 8 can counterweight the tensioning roller 9, thereby increasing the gravity exerted on the tensioning roller 9, so that the conveyor belt 2 can be pulled downward by the tensioning roller 9 to make it in a taut state, thereby avoiding the conveyor belt 2 from being loose, ensuring the normal transportation of materials, and during the rotation of the conveyor belt 2, the residual materials and dust on it will also fall on the top of the material cleaning block 8, and at the same time, the left and right sides of the material cleaning block 8 The blade-like structure on the top can also clean the surface of the conveyor belt 2. Because the top of the material cleaning block 8 is an inclined surface, the material on the top of the material cleaning block 8 will slide forward and backward and fall downward. At this time, the No. 1 baffle 4 and the No. 2 baffle 6 can cooperate to block the residual material and dust on the conveyor belt 2, so that these materials and dust can only fall in the cavity inside the No. 1 baffle 4 and the No. 2 baffle 6, and will not float outward. Moreover, when the conveyor belt 1 breaks, the tensioning roller 9 and the material cleaning block 8 will fall rapidly due to gravity under the support of the adjustment guide rail 3. At this time, the lower protective baffle 7 can resist the tensioning roller 9 and the material cleaning block 8. At the same time, the thick rubber pad on the top of the lower protective baffle 7 can play a buffering role to prevent the tensioning roller 9 from falling outward and causing harm to nearby personnel.
