DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1 - 4 , the present utility model provides a technical solution: a scraper device for a shallow - trough separator, including

[0025] a scraper assembly 100, the scraper assembly 100 includes a mounting plate 101 and an arc scraper 102 disposed on the surface of the mounting plate 101;

[0026] The scraper assembly 100 further includes mounting posts 103 fixedly provided on both side surfaces of the mounting plate 101, and both ends of the two mounting posts 103 away from the mounting plate 101 are fixedly connected to the surfaces of two chains on the shallow - trough separator, so that the scraper assembly 100 can move along with the chains.

[0027] The surface of the arc-shaped scraper 102 is evenly provided with a number of first through holes 104 facilitating the passage of fluid, and the surface of the mounting plate 101 is provided with two groups of symmetrical second through holes 105 facilitating the passage of fluid, which will not cause fluid blockage.

[0028] The connecting component 200 is used for quickly connecting the arc-shaped scraper 102 and the mounting plate 101. The connecting component 200 includes plug-in blocks 201 fixed at two ends of the arc-shaped scraper 102, and plug-in slots 202 opened on the surface of the mounting plate 101 and adapted to the plug-in blocks 201. The connecting component 200 further includes a rectangular cavity 203 opened inside the mounting plate 101, and two symmetrical fixing blocks 204 fixed on the inner wall of the rectangular cavity 203. A bidirectional threaded column 205 penetrating through the two fixing blocks 204 is rotatably arranged on the surfaces of the two fixing blocks 204. And two symmetrical rectangular positioning columns 206 are slidably arranged on the inner wall of the rectangular cavity 203. Column-shaped threaded grooves 207 respectively threadedly connected to the outer surfaces of both ends of the bidirectional threaded column 205 are opened at the ends of the two rectangular positioning columns 206. Rectangular holes for the rectangular positioning columns 206 to slide are opened on both inner walls of the rectangular cavity 203 and extend into the plug-in slots 202. Positioning holes 208 and positioning grooves 209 adapted to the rectangular positioning columns 206 are respectively opened on the surface of the plug-in block 201 and the inner wall of the plug-in slot 202.

[0029] A limiting slider 2015 is fixed on the lower surface of the rectangular positioning column 206, and a limiting sliding groove 2016 for the limiting slider 2015 to slide is opened on the inner bottom wall of the rectangular cavity 203.

[0030] A limiting slide bar 2017 is fixed on the inner wall of the limiting sliding groove 2016, and a sliding hole slidably connected to the outer surface of the limiting slide bar 2017 is opened on the surface of the limiting slider 2015.

[0031] The settings of the limiting slider 2015, the limiting slide bar 2017 and the limiting sliding groove 2016 effectively ensure the stability of the rectangular positioning column 206 during the moving process and can control the moving range of the rectangular positioning column 206.

[0032] A rotating block 2010 for rotating the bidirectional threaded column 205 is arranged on the surface of the mounting plate 101.

[0033] A rotating groove 2011 is opened on the surface of the mounting plate 101, and a rotating shaft 2012 extending into the rectangular cavity 203 is rotatably arranged on the inner wall of the rotating groove 2011.

[0034] The rotating block 2010 is rotatably connected to the inner wall of the rotating groove 2011, and a hexagonal operation groove 2013 for facilitating the rotation of an external hexagonal wrench is formed on the surface of the rotating block 2010. Conical gears 2014 that mesh with each other are fixedly provided on the other end of the rotating shaft 2012 and the surface of the bidirectional threaded column 205.

[0035] Among them, for this shallow groove separator scraper device, by providing the connection assembly 200, when the arc-shaped scraper 102 is damaged and needs to be replaced during the actual use of the scraper assembly 100, the rotating block 2010 can be rotated to achieve the purpose of quickly disassembling and installing the damaged arc-shaped scraper 102, thereby effectively solving the defect in the prior art that the scraping plate cannot be quickly replaced.

[0036] During operation, when the arc-shaped scraper 102 is damaged and needs to be replaced during the actual use of the scraper assembly 100, the rotating block 2010 can be rotated by an external internal hexagonal wrench. The rotation of the rotating block 2010 drives the rotation of the rotating shaft 2012. The rotation of the rotating shaft 2012 drives the rotation of the bidirectional threaded column 205 under the action of the two conical gears 2014. The rotation of the bidirectional threaded column 205 drives the two rectangular positioning columns 206 to move towards the middle simultaneously under the action of the cylindrical threaded groove 207, so that the rectangular positioning columns 206 are separated from the positioning groove 209 and the positioning hole 208 respectively. Then, the arc-shaped scraper 102 can be pulled out upwards to achieve the quick disassembly of the arc-shaped scraper 102. At the same time, when installing a new arc-shaped scraper 102, the insertion block 201 on the arc-shaped scraper 102 can be inserted into the insertion slot 202 on the mounting plate 101, and the rotating block 2010 can be rotated in the reverse direction using a hexagonal wrench, thereby driving the two rectangular positioning columns 206 to move towards both sides simultaneously, so that the rectangular positioning columns 206 respectively pass through the positioning holes 208 on the insertion block 201 and are inserted into the positioning grooves 209 on the insertion slot 202 to achieve the quick installation of the arc-shaped scraper 102, and further enabling the device to achieve the purpose of quickly disassembling and installing the damaged arc-shaped scraper 102, thereby effectively solving the defect in the prior art that the scraping plate cannot be quickly replaced.

[0037] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
