DETAILED DESCRIPTION
[0015] The utility model is further described below in combination with specific embodiments, and the purpose is only to better understand the content of the utility model, therefore, the example does not limit the protection scope of the utility model.
[0016] As Figure 1 , Figure 2As shown, this embodiment provides a belt sweeper, including two side support frames 1. One side of each side support frame 1 has a connecting seat 2, and the other side has a guide post 4. The two side support frames 1 are respectively fixed to the unloading arms 3 on the left and right sides of the belt conveyor via the connecting seats 2. The two side support frames 1 are detachably connected to the unloading arms 3, thereby allowing adjustment of the relative position between the belt sweeper and the belt conveyor according to usage requirements. The guide post 4 is vertically arranged, and an adjusting nut 5 is threaded onto the guide post 4. A support spring 6 is provided on the adjusting nut 5, and a connecting sleeve 7 is provided on the support spring 6. The connecting sleeve 7 is connected to... The support springs 6 are all sleeved on the guide post 4; by rotating the adjusting nut 5, the height of the two connecting sleeves 7 can be adjusted to adapt to belts of different heights; a first clamping plate 8 is connected between the two connecting sleeves 7, and a second clamping plate 10 is bolted to the front side of the first clamping plate 8. The first clamping plate 8 and the second clamping plate 10 hold the coal scraper 9; by setting the support springs 6, the coal scraper 9 can be closely attached to the belt, making full use of the reset and buffering functions of the support springs 6, so that the coal scraper 9 is closely attached to the belt and the gap between the scraper 9 and the belt can be automatically and quickly changed, thereby better filtering the coal powder adhering to the belt.
[0017] like Figure 1 , Figure 2 The connecting seat 2 includes an upper connecting plate and a lower connecting plate. The distance between the upper connecting plate and the lower connecting plate 202 is adapted to the thickness of the unloading arm 3. The upper connecting plate and the lower connecting plate are snapped onto the unloading arm 3 and fixed to the unloading arm 3 by connecting bolts and connecting nuts.
[0018] The side support frame 1 has a top plate 101 at the upper end and a bottom plate 102 at the lower end. The guide column 4 passes through the top plate 101 and the bottom plate 102 and is fixed to the top plate 101 and the bottom plate 102 by mounting nuts.
[0019] In this embodiment, the scraper plate 9 is made from a discarded conveyor belt; it is low in cost, has a certain degree of elasticity and hardness, avoiding rigid friction between the scraper plate 9 and the conveyor belt and preventing belt scratches. When it is necessary to adapt to conveyor belts of different widths, the width of the scraper plate 9 inside the first clamping plate 8 and the second clamping plate 10 can be changed.
[0020] This utility model has a simple structure, strong applicability, and is economical and durable.
