Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyors, in particular to a belt cleaner. Background Art

[0002] Belt conveyors have the advantages of large conveying capacity, simple structure, easy maintenance, and standardized components. They are used to convey loose materials or finished items and are widely used in various industries. In the garbage disposal industry, especially in the treatment of stale garbage, due to the complexity of the composition of the transported materials and the harsh working environment, some viscous fluid-like wet materials are often transported, which adhere to the belt. On the one hand, the load increases, causing motor power loss. On the other hand, sticky materials will harden after adhering to the drum for a long time, affecting the service life of the belt. At present, belt cleaners often use compression springs as the clamping mechanism, but this structure is adjusted through nuts, and the operation requires wrench space, which is more troublesome. In addition, it is impossible to quantify the actual pressure. Excessive pressure affects the life of the belt and increases the load on the motor. Too little pressure will not achieve the cleaning effect. Utility Model Content

[0048] like Figure 1-Figure 5 As shown, the utility model provides a belt cleaner, comprising:

[0049] A tension adjustment portion for generating a variety of different tensions;

[0050] A force transmission part connected to the tension adjustment part;

[0051] A scraper assembly connected to the force transmission part;

[0052] The tension generated by the tension adjustment part is transmitted to the scraper assembly through the force transmission part, so that the scraper assembly is pressed against the conveying belt 16 of the belt conveyor according to the tension.

[0053] In this embodiment, the tension generated by the tension adjusting part is transmitted to the scraper assembly through the force transmission part, so that the scraper assembly is pressed against the conveyor belt 16 of the belt conveyor according to the tension, and the conveyor belt 16 of the belt conveyor is cleaned by the scraper assembly; by adjusting the tension of the tension adjusting part, the pressing force between the scraper assembly and the conveyor belt 16 of the belt conveyor is adjusted, and the adjustment operation is simple and convenient; the tension adjusting part can realize the adjustment of a variety of different tensions, thereby ensuring the cleaning effect of the conveyor belt 16 without increasing the load on the motor.

[0054] like Figure 1 and Figure 3 As shown, in an optional embodiment of the utility model, the tension adjustment part includes:

[0055] A height-adjustable adjustment plate 4 is arranged outside the belt side plate 15;

[0056] A force transmission connecting rod 2, connected to the force transmission part;

[0057] The tension spring 3 has one end fixedly connected to the force transmission connecting rod 2 and the other end fixedly connected to the adjustment plate 4.

[0058] In this embodiment, when multiple different tension adjustments of the tension adjustment part are required, the stretching length of the tension spring 3 is adjusted by adjusting the height of the adjustment plate 4, thereby achieving the adjustment of multiple different tensions. Through the stretching length of the tension spring 3, based on Hooke's law, the size of the clamping force of the scraper assembly on the conveyor belt 16 can be judged to ensure that the clamping force is moderate. While ensuring the cleaning effect of the scraper assembly on the conveyor belt 16, it will not increase the load on the motor, which helps to extend the service life of the conveyor belt 16.

[0059] like Figure 1 and Figure 3 As shown, in an optional embodiment of the utility model, the tension adjustment part also includes:

[0060] Adjust the fixing plate 6 and fix it to the outer side of the belt side plate 15;

[0061] A fixing screw 12 is arranged on the outside of the adjusting fixing plate 6;

[0062] A plurality of quantitative adjustment holes 14 are arranged on the surface of the adjustment plate 4 . The quantitative adjustment holes 14 correspond to the fixing screw pins 12 , and the quantitative adjustment holes 14 are evenly distributed along the length direction of the adjustment plate 4 .

[0063] In this embodiment, the connection between the adjustment plate 4 and the adjustment fixing plate 6 is achieved through the fixing screw 12 and the quantitative adjustment hole 14; when adjusting the height of the adjustment plate 4, the fixing screw 12 is inserted into the quantitative adjustment hole 14 at different height positions to achieve the height of the adjustment plate 4, and the operation is simple and convenient.

[0064] like Figure 1 and Figure 3 As shown, in an optional embodiment of the present utility model, a limiting ring is provided at the end of the fixing screw 12 away from the adjusting fixing plate 6;

[0065] The quantitative adjustment hole 14 is in a gourd-shaped structure as a whole. The inner diameter of the small hole at the upper part of the quantitative adjustment hole 14 is smaller than the outer diameter of the limiting ring, and the inner diameter of the large hole at the lower part of the quantitative adjustment hole 14 is larger than the outer diameter of the limiting ring.

[0066] In this embodiment, the fixing screw 12 enters the quantitative adjustment hole 14 through the lower hole of the quantitative adjustment hole 14. Under the action of the tension spring 3, the fixing screw 12 enters the upper small hole of the quantitative adjustment hole 14. The limiting ring and the upper small hole of the quantitative adjustment hole 14 cooperate to limit the fixing screw 12, which can prevent the fixing screw 12 from detaching from the quantitative adjustment hole 14, thereby ensuring the stability of the adjustment plate 4.

[0067] like Figure 1As shown, in an optional embodiment of the utility model, the tension adjustment part also includes:

[0068] The adjusting handle 13 is connected to the upper part of the adjusting fixing plate 6 .

[0069] In this embodiment, the adjustment handle 13 is adjusted to facilitate pulling the adjustment plate 4 upwards to adjust the height of the adjustment plate 4 .

[0070] like Figure 1 As shown, in an optional embodiment of the utility model, the force transmission part includes:

[0071] A rotating fixed plate 1 connected to the belt side plate 15;

[0072] A flip rod 10 is rotatably connected between the two rotating fixed plates 1, and one end of the flip rod 10 is connected to the force transmission connecting rod 2;

[0073] A force transmission lever plate 11 is arranged on the outside of the flip rod 10, and the force transmission lever plate 11 is connected to the scraper assembly.

[0074] In this embodiment, under the pulling action of the tension spring 3, the force transmission connecting rod 2 drives the flip rod 10, and the flip rod 10 drives the force transmission lever plate 11, so that the force transmission lever plate 11 applies force to the scraper assembly, so that the scraper assembly presses the conveyor belt 16, and the conveyor belt 16 is cleaned by the scraper assembly.

[0075] like Figure 1 and Figure 2 As shown, in an optional embodiment of the utility model, the scraper assembly includes:

[0076] The scraper mounting plate 7, the bottom surface of the scraper mounting plate 7 is in contact with the force transmission lever plate 11;

[0078] The rubber scraper 9 is clamped and fixed between the scraper clamping plate 8 and the scraper mounting plate 7;

[0079] Two flip plates 5 are provided, and the two flip plates 5 are connected to the two ends of the scraper mounting plate 7. The flip plates 5 are rotatably connected to the belt side plates 15 through a rotating shaft.

[0080] In this embodiment, the force transmission lever plate 11 follows the flip rod 10 and applies force to the scraper mounting plate 7, so that the scraper mounting plate 7 rotates through the rotating shaft and the flip plate 5, so that the rubber scraper 9 presses the conveyor belt 16, and the conveyor belt 16 is cleaned by the rubber scraper 9;

[0081] The contact between the rubber scraper 9 and the conveyor belt 16 is achieved by rotating, so that a certain angle is formed between the rubber scraper 9 and the conveyor belt 16, which can improve the cleaning effect of the rubber scraper 9 on the conveyor belt 16;

[0082] The rubber scraper 9 is clamped and fixed by the scraper mounting plate 7 and the scraper clamping plate 8, so that the rubber scraper 9 can be easily disassembled, assembled and replaced, thereby ensuring the cleaning effect on the conveyor belt 16.

[0083] like Figure 4 As shown, in an optional embodiment of the present utility model, the contact portion between the force transmission lever plate 11 and the scraper mounting plate 7 is an arc-shaped structure;

[0084] The contact position between the force transmission lever plate 11 and the scraper mounting plate 7 is located in the middle of the scraper mounting plate 7 .

[0085] In this embodiment, the contact portion between the force transmission lever plate 11 and the scraper mounting plate 7 adopts an arc-shaped structure. When the force transmission lever plate 11 rotates with the flip rod 10 to support the scraper mounting plate 7 upward, the friction between the force transmission lever plate 11 and the scraper mounting plate 7 can be reduced, thereby ensuring the supporting effect of the force transmission lever plate 11 on the scraper mounting plate 7 while saving the adjustment force of the operator.

[0086] By making the force transmission lever plate 11 contact the middle part of the scraper mounting plate 7, the scraper mounting plate 7 can be evenly stressed, ensuring that the rubber scraper 9 is in accurate and full contact with the conveyor belt 16, thereby ensuring the cleaning effect of the conveyor belt 16.

[0087] like Figure 3 As shown, in an optional embodiment of the present invention, the force transmission connecting rod 2 and the force transmission lever plate 11 are arranged in parallel, and the extension direction of the force transmission connecting rod 2 and the force transmission lever plate 11 is the same.

[0088] In this embodiment, the above structure can be used to easily observe the position and angle of the force transmission lever plate 11, which is convenient for judgment and ensures that the rubber scraper 9 is in full and accurate contact with the conveyor belt 16.

[0089] like Figure 3 and Figure 5 As shown, in an optional embodiment of the present utility model, the ends of the force transmission connecting rod 2 and the adjustment plate 4 are both provided with through holes for fixed connection with the tension spring 3;

[0090] The two ends of the flip rod 10 respectively penetrate the mounting through holes 17 on the surfaces of the two rotating fixed plates 1, and the flip rod 10 rotates in cooperation with the mounting through holes 17;

[0091] A limit cavity 18 is provided through the surface of the rotating fixed plate 1 away from the force transmission connecting rod 2, and the limit cavity 18 is communicated with the installation through hole 17;

[0092] A limiting protrusion 19 is formed on the outer side of the flip rod 10 away from the force transmission connecting rod 2 , and the limiting protrusion 19 is located inside the limiting cavity 18 .

[0093] In this embodiment, the above structure is adopted to facilitate the disassembly, assembly and replacement of the tension spring 3, thereby ensuring the pulling effect of the tension spring 3 on the force transmission connecting rod 2;

[0094] When adjusting the clamping force or disassembling and replacing the tension spring 3, the flip rod 10 is limited by the cooperation of the limiting protrusion 19 and the limiting cavity 18, so that the force transmission lever plate 11 is limited under the scraper assembly to prevent the scraper assembly from rotating with the flip plate 5, thereby causing the force transmission lever plate 11 to be disengaged from the scraper assembly, thereby avoiding adjustment failure and damage accidents during operation.

[0095] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
