Description

Technical Field

[0001] This utility model relates to the field of sweeper technology, and in particular to a belt sweeper. Background Technology

[0002] Belt cleaners are used to scrape off material adhering to the return conveyor belt. Patent application number 201520982351.7 discloses a belt cleaner comprising blades and a blade holder. Telescopic rods are located at both ends of the blade holder, and a tensioner arm and a tensioner support are sequentially fixed to the telescopic rods along the axial direction. The tensioner support is connected to an axially rotating clamping mechanism, the clamping end of which is engaged with the long arm of the tensioner arm. The cleaner adjusts the blade rotation angle by adjusting the direction of the pull rod, causing the clamping mechanism to push the tensioner arm to a certain position. The lateral distance of the blades is adjusted through a clever structural cooperation between the tensioner arm and the flange sleeve. However, when replacing blades due to wear, the spring and tension nut need to be removed so that the tensioner arm can rotate significantly, thereby rotating the blade holder. This facilitates the disassembly and installation of the bolts and nuts used to fix the blades to the blade holder, which is rather cumbersome. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a belt sweeper in response to the above-mentioned technical deficiencies.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a belt cleaner, including a rotating shaft, a scraper detachably connected to the rotating shaft, mounting seats rotatably connected to both ends of the rotating shaft, the upper end of a swing arm also connected to the end of the rotating shaft, one end of a screw rotatably connected to the mounting seat, a push ring provided at the end of the swing arm away from the rotating shaft, the screw passing through a through hole on the push ring and then through a spring and connected to a tension nut, an open washer provided between the spring and the push ring, the width of the notch on the open washer being greater than the diameter of the screw and less than the inner diameter of the spring, and the diameter of the through hole being greater than the diameter of the spring.

[0005] To further optimize this technical solution, a protrusion is provided on the side of the push ring near the opening gasket, and a groove is provided on the opening gasket to accommodate the protrusion.

[0006] To further optimize this technical solution, a large collar is provided at the upper end of the swing arm, and multiple through holes are provided on the large collar. Multiple threaded holes are provided on the rotating shaft, and bolts are connected to the threaded holes after passing through the through holes.

[0007] To further optimize this technical solution, a pin is provided at the lower part of the mounting base, and a small collar is provided at one end of the screw, with the small collar rotatably connected to the pin.

[0008] Compared with the prior art, the present invention has the following advantages: a push ring is provided at one end of the swing arm, and an open gasket is located between the spring and the push ring. By removing the open gasket, the spring can be inserted into the through hole on the push ring. The scraper and the rotating shaft can be rotated at a certain angle without removing the spring, which makes it convenient to replace the scraper. Attached Figure Description

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0014] Detailed implementation method: combined with Figure 1-3 As shown, a belt cleaner includes a rotating shaft 3, on which a scraper 2 is detachably connected. Mounting seats 1 are rotatably connected to both ends of the rotating shaft 3, and the mounting seats 1 are used to fix it to a belt conveyor. The upper end of a swing arm 6 is also connected to the end of the rotating shaft 3. Rotation of the swing arm 6 can drive the rotating shaft 3 and the scraper 2 to rotate. One end of a screw 4 is rotatably connected to the mounting seat 1. A push ring 62 is provided at the end of the swing arm 6 away from the rotating shaft 3. The screw 4 passes through a through hole 621 on the push ring 62 and then through a spring 5 to connect with a tension nut. An open washer 7 is provided between the spring 5 and the push ring 62. When the spring 5 is compressed to a certain extent, the open washer 7 is tightly pressed against the push ring 62. The width of the notch 71 on the open washer 7 is greater than the diameter of the screw 4 and smaller than the inner diameter of the spring 5. The diameter of the through hole 621 is several millimeters larger than the diameter of the spring 5, and the open washer 7 cannot pass through the through hole 621.

[0015] Furthermore, the push ring 62 is provided with a protrusion 622 on the side near the opening gasket 7, and the opening gasket 7 is provided with a groove 72 for accommodating the protrusion 622. The length and width of the groove 72 are both greater than the length and width of the protrusion 622, respectively. When the spring 5 is in a compressed state, the opening gasket 7 will not fall off the push ring 62.

[0016] Specifically, the upper end of the swing arm 6 is provided with a large collar 61, the large collar 61 is provided with multiple through holes, the rotating shaft 3 is provided with multiple threaded holes, and the bolt passes through the through holes and connects with the threaded holes.

[0017] Specifically, a pin is provided at the lower part of the mounting base 1, and a small collar is provided at one end of the screw 4, which is rotatably connected to the pin.

[0018] When replacing scraper 2, first loosen the tension nut so that spring 5 is not compressed (at this time, the tension nut is still on screw 4). Then remove the open washer 7, and then insert spring 5 into the through hole 621. After that, you can... Figure 1 The upper side of the scraper 2 is rotated to the left at a certain angle (during this process, the swing arm 6 and the screw 4 will rotate as well). At this time, the operator can be positioned on the left side of the belt conveyor to replace the scraper 2, which is more convenient.
