Description

Technical Field

[0001] This utility model belongs to the technical field of belt conveyor cleaners, and specifically relates to a cleaner with independently adjustable blades and springs. Background Technology

[0002] In the current belt conveyor industry, most systems employ sweepers to clean the conveyor belts, removing residual material and maintaining normal belt operation. Since the sweeper's blades need to contact the conveyor belt during cleaning, the degree of contact between the blades and the belt is crucial; a higher degree of contact results in better cleaning. However, existing conveyor belts have diverse surface shapes, including uneven surfaces. This new belt conveyor blade-adjustable spring-loaded sweeper addresses this issue, allowing for better contact between the blades and the conveyor belt surface, thereby improving cleaning efficiency. Utility Model Content

The pin 19 passes through the connecting hole at the bottom of the adjusting plate 27 and the connecting hole on the blade assembly base plate 28, and is fixed by the pin 20.

[0009] Furthermore, a dirt baffle 26 is fixed to the blade fixing plate 21 by a third fixing bolt 22. The dirt baffle 26 is fixed to the blade fixing plate 21 by two third fixing bolts 22. The two third fixing bolts 22 pass through the blade fixing plate 21 from front to back and are fixed by a fourth washer 23, a fourth spring washer 24, and a second locking nut 25.

[0010] Furthermore, the blade assembly 4 is mounted on the main bracket 2 by a first fixing bolt 6, which passes through the blade assembly base plate 28 and the main bracket 3, and is then fixed by a first washer 7, a first spring washer 8, and a first nut 9.

[0011] Furthermore, the blade 10 is mounted on the top of the blade fixing plate 21 by an internal hex bolt 11, and then fixed by a second washer 12, a second spring washer 13, and a first lock nut 14.

[0012] Furthermore, each blade fixing plate 21 is equipped with two second fixing bolts 15, which pass through the corresponding round holes at the blade fixing plate 21 and the adjusting plate 27 from front to back, and are then fixed using a third washer 16, a third spring washer 17, and a second nut 18.

[0013] Furthermore, the bottom of the blade assembly base plate 28 is provided with two round holes, and the blade assembly base plate 28 is equipped with two first fixing bolts 6. The two first fixing bolts 6 pass through the corresponding round holes of the blade assembly base plate 28 and the main bracket 2 from top to bottom, and are fixed to the main bracket 2 by the first washer 7, the first spring washer 8, and the first nut 9.

[0014] Furthermore, the tensioner 1 includes a sleeve 34 and a connecting plate 35. One end of the auxiliary bracket 3 is inserted into the main bracket 2.

[0017] Furthermore, the connecting plate 35 is connected to the lower end of the sweeper mounting bracket 41 via four sets of bolt assemblies 40.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In this invention, the blades on the cleaner adhere better to the surface of the conveyor belt, thereby improving the cleaning effect. Specifically, in this invention, each blade is mounted on a blade assembly. Because there is an adjusting spring in the middle of the blade assembly, the blade assembly is elastic, so each blade has vertical tension, which allows it to adhere to the conveyor belt even when the conveyor belt is running and jumping, thus improving the cleaning effect.

[0020] 2. The blade in this utility model is made of all-metal material, which greatly improves the temperature resistance and wear resistance of the device, and is better able to adapt to the friction loss and high temperature generated when the belt of the belt conveyor is running and the cleaner is working, thus greatly improving the service life of the blade.

[0021] 3. The blade assembly in this utility model has a baffle plate, which prevents the garbage and impurities generated during operation from entering the blade assembly, thereby improving its service life.

[0022] 4. This utility model has a simple structure and is easy to install and maintain. Its blade assembly is composed of multiple parts. When a part is damaged, it can be directly replaced simply by removing the damaged part, without the need for overall disassembly, which greatly increases the convenience of on-site maintenance.

The connecting plate 35 is connected to the lower end of the sweeper mounting frame 41 via four sets of bolt assemblies 40.

[0040] In the process of using this utility model, the tensioner 1 needs to be connected to the belt conveyor bracket 42 through the cleaner mounting bracket 41. Each main bracket 2 is equipped with a secondary bracket 3 and a tensioner 1 at both ends. The tensioner 1 includes a sleeve 34. One end of the secondary bracket 3 is inserted into the main bracket 2. The locking bolt 5 passes through the second fixing nut 39 and the bottom of the main bracket 2 and abuts against the bottom of the secondary bracket 3. The other end of the secondary bracket 3 is inserted into the tensioner 1 and passes through the sleeve 34. The fourth fixing bolt 37 passes through the sleeve 34 and abuts against the outer wall of the secondary bracket 3. The fourth fixing bolt 37 is also fitted with a first fixing nut 36. The fourth fixing bolt 37 passes through the first fixing nut 36 and the outer wall of the sleeve 34 in sequence, and abuts against the upper surface of the auxiliary bracket 3.

The connecting plate 35 is connected to the lower end of the sweeper mounting frame 41 through four sets of bolt assembly 40.

[0041] The specific method for adjusting the blade position of the blade assembly in this utility model is as follows: When adjusting the blade up and down of each individual blade assembly 4, the adjustment is made by the third locking nut 33. After adjusting to the appropriate position, that is, after the blade 10 is in contact with the concave and convex surfaces of the conveyor belt 38, the fifth washer 31, the fifth spring washer 32, and the third locking nut 33 are tightened together to prevent each individual blade assembly 4 from loosening.

[0042] When this utility model is used, the belt conveyor with the conveyor belt 38 is fixed on the belt conveyor bracket 42. The fixed connection relationship between the conveyor belt 38, the belt conveyor and the belt conveyor bracket 41 is the prior art.

[0043] This utility model is a cleaner used on the return belt of a belt conveyor near the head pulley. It is suitable for various belt conveyors, such as those used in coal mines, power plants, ports, cement plants, and grain depots. In this utility model, the number of cleaning channels of the cleaner body can be increased during installation according to the cleaning requirements. Specifically, the cleaner body is positioned at the head pulley of the conveyor belt 38 for cleaning.

[0044] In this invention, the blades on the cleaner adhere better to the surface of the conveyor belt, thereby improving the cleaning effect. Specifically, in this invention, each blade is mounted on a blade assembly. Because there is an adjusting spring in the middle of the blade assembly, the blade assembly is elastic, so each blade has vertical tension, which allows it to adhere to the conveyor belt even when the conveyor belt is running and bouncing, thus improving the cleaning effect.

[0045] The blade in this invention is made of all-metal material, which greatly improves the temperature resistance and wear resistance of the device, and is better able to adapt to the frictional loss and high temperature generated when the belt of the conveyor belt is running and the cleaner is working, thus greatly improving the service life of the blade.

[0046] The blade assembly of this invention includes a baffle plate, which prevents debris and impurities generated during operation from entering the blade assembly, thereby improving its service life.

[0047] This invention features a simple structure and is easy to install and maintain. Its blade assembly is composed of multiple parts; if a part is damaged, it can be directly replaced simply by removing the damaged part, eliminating the need for complete disassembly and greatly increasing the convenience of on-site repair and maintenance.

[0048] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
