DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will further describe the present application in detail Figures 1-4 with reference to the accompanying drawings.

[0021] The present application embodiment discloses a fixed balanced spring cleaner for a belt conveyor, referring to Figures 1-4 , including a cleaning mechanism 1 and a mounting mechanism 2, the cleaning mechanism 1 is mounted on the mounting mechanism 2, the number of the mounting mechanisms 2 is set to two, the two mounting mechanisms 2 are symmetrically mounted on the middle frame of the belt conveyor, the mounting mechanism 2 includes symmetrically arranged mounting components, the mounting components include a suspension rod 21, a spring 22, an upper limit nut 23, an elastic force adjustment nut 24 and supports 25 symmetrically arranged at both ends of the suspension rod 21, the supports 25 are fixed on the middle frame of the belt conveyor, the suspension rod 21 is vertically fixed on the two supports 25, the suspension rod 21 is connected to the supports 25 by a nut locking, the elastic force adjustment nut 24 and the upper limit nut 23 are both threadedly screwed on the suspension rod 21, and are arranged between the two supports 25, the spring 22 is sleeved on the suspension rod 21, and is arranged between the upper limit nut 23 and the elastic force adjustment nut 24.

[0022] By providing the upper limit nut 23, the upper limit of the cleaning mechanism 1 of the sweeper can be adjusted to control the wear height of the scraper 12, thereby preventing the rigid material from damaging the conveyor belt after the scraper 12 is worn.

[0023] The position of the spring 22 is adjusted by the elastic force adjustment nut 24 to always keep the scraper 12 in close contact with the belt surface on the return journey to achieve a better cleaning effect.

[0024] The cleaning mechanism 1 includes a support frame 11, a scraper 12, a pressure plate 13 and a balancing fixed frame 14. The balancing fixed frame 14 includes a support sleeve 141 and a balancing bracket 142 symmetrically fixed on both sides of the support sleeve 141. A through hole is opened on the balancing bracket 142 at the position corresponding to the suspension rod 21, and the bottom end of the balancing bracket 142 is fixedly connected to the top end of the spring 22. The support frame 11 is fixedly connected in the support sleeve 141. A connecting plate 112 is welded and fixed on the support frame 11. The scraper 12 is fixed to the connecting plate 112 by bolts through the pressure plate 13.

[0025] Reference Figure 1 and Figure 3 A plurality of positioning screws 15 are threadedly connected to the support sleeve 141 , and the positioning screws 15 can abut against the support frame 11 . Angle correction holes 111 for correcting the angle are respectively provided at both ends of the support frame 11 .

[0026] When adjusting the angle of the scraper 12, insert an axial tool into the angle correction hole 111, and turn the tool to drive the support frame 11 to rotate, so that the angle of the scraper 12 can be adjusted.
