DETAILED DESCRIPTION

[0015] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0016] Combined with Figure 1 To Attachment Figure 5 A discharging scraper that is easy to replace includes a chain 1. The chain 1 is provided with two and parallel to each other. The chain 1 is composed of a plurality of elliptical steel rings. A plurality of fixed plates 2 are evenly installed between the two chains 1. Both sides of the fixed plate 2 are welded to the elliptical steel rings in the horizontal direction of the chain 1. Two fixed blocks 3 are welded on the left and right ends of the fixed plate 2. First square chutes 8 are respectively opened on the opposite sides of the two fixed blocks 3. A scraper 4 is installed between the two fixed blocks 3. Second square chutes 5 are opened at the lower ends of the front and rear sides of the scraper 4. A first groove 6 is symmetrically opened at the lower end of the left side of the scraper 4. The first groove 6 is communicated with the second square chute 5. A fixing device 7 is installed in the first groove 6 and the second square chute 5.

[0017] The fixing device 7 includes a square fixing cylinder 9, which is fixedly installed in the first groove 6 at one end close to the second square slide groove 5. The square fixing cylinder 9 is communicated with the second square slide groove 5. A fixing rod 10 slides in the square fixing cylinder 9 and the second square slide groove 5. A limiting block 11 is installed at one end of the fixing rod 10 located in the first groove 6. A spring 12 is sleeved on the outside of the square fixing cylinder 9 and the fixing rod 10. One end of the spring 12 is fixedly installed on the first groove 6 at one end of the square 76 fixing cylinder 9. The other end of the spring 12 is fixedly installed on the limiting block 11. The fixing rod 10 slides in the first square slide groove 8 and the second square slide groove 5.

[0018] Specifically, when installing the scraper 4, use both hands to pull the limit blocks 11 respectively, and the limit blocks 11 drive the fixing rod 10 to slide in the second square slot 5 and the square fixing tube 9, so that the fixing rod 10 is retracted into the second square slot 5, and the spring 12 is in a stretched state, and then the two sides of the scraper 4 are aligned with the first square slot 8 on the fixing block 3, and then the limit blocks 11 are released. Under the elastic force of the spring 12, the spring 12 pulls the limit blocks 11 to move the fixing rod 10 from the second square slot 5 to the first square slot 8, thereby fixing the scraper 4. When replacing the scraper 4, you only need to pull the limit blocks 11 by hand to retract the fixing rod 10 into the second square slot 5 to replace the scraper 4, which is convenient and quick.

[0019] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
