Abstract
Description
Technical Field
[0001] The utility model belongs to the field of scraper devices, in particular to a scraper chain anti-carrying device. Background Art
[0002] A scraper is a transport machine that is a continuous transport device that transports bulk materials in a closed rectangular cross-section housing with the help of a moving scraper chain. Since the scraper chain is completely buried in the material when transporting the material, it is called a scraper. The machine has a simple structure, is easy to install and maintain, and has flexible process layout.
[0003] In the prior art, scrapers are often used in the material transfer process. When the material is transported to the silo by the scraper, the material will fall from the outlet of the silo gate into the inlet of the silo. However, when the scraper is running, the particles on the chain cannot enter the designated silo, that is, some of the material particles attached to the chain are difficult to be brought into the silo in time. This part of the material is brought into other silos along with the chain, resulting in material cross-binding. Utility Model Content
[0004] The utility model provides a device for preventing a scraper chain from carrying materials, which is used to solve the technical problems raised in the above-mentioned background technology.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] The scraper chain anti-carrying device comprises a scraper, a chain is slidably installed inside the scraper, scrapers adapted to the inner wall of the scraper are arranged at intervals on the chain, a silo feed port is arranged at the lower end of the scraper, an adjustment mounting seat is arranged on the inner wall of the scraper at a position above the chain close to the silo feed port, and the adjustment mounting seat is connected with an air nozzle aligned with the chain and the silo feed port through an air pipe.
[0007] Compared with the prior art, the beneficial effects of the utility model are:
[0008] The utility model adjusts the settings of the mounting seat, the air pipe, the air nozzle and other structures so that the device can use the air nozzle to aim at the chain and blow off the material particles attached to it, effectively preventing this part of the material from being brought into other silos along with the chain, causing material to cross silos.
[0009] As a further improvement of the above solution, support bars with a downwardly concave middle portion are arranged at intervals on the top of the silo feed port.
[0010] The technical effect of the above improvement is: through the setting of the support strip, the scraper of the device will not scratch the edge of the top of the silo feed port during movement, avoiding affecting the normal operation of material transportation in the trough.
[0011] As a further improvement of the above solution, a gate plate is provided on one side of the silo feed port below the support bar.
[0012] The technical effect of the above improvement is that through the setting of the gate plate, the device can further facilitate the control of the opening and closing of the silo feed port to feed.
[0013] As a further improvement of the above solution, support guide wheels adapted to the bottom surface of the gate plate are arranged at intervals in the feed port of the silo.
[0014] The technical effect of the above improvement is: by setting the supporting guide wheel, the device can support and guide the sliding of the gate plate, making its sliding process smoother. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to enable those skilled in the art to better understand the technical solution, the utility model is described in detail below in conjunction with embodiments. The description in this section is only exemplary and explanatory and should not have any limiting effect on the protection scope of the utility model.
[0019] Embodiment 1:
[0020] like Figure 1-2 As shown, the specific scheme of this embodiment is: a scraper chain anti-carrying device comprises a scraper 1, a chain 2 is slidably installed in the scraper 1, and scrapers 3 adapted to the inner wall of the scraper 1 are arranged at intervals on the chain 2. As the chain 2 moves, the scrapers 3 are driven to slide in the material trough of the scraper 1 and transport materials. A silo feed port 5 is arranged at the lower end of the scraper 1, and the upper end of the silo feed port 5 is opened upward. An adjusting mounting seat 8 is arranged on the inner side wall of the scraper 1 at a position above the chain 2 close to the silo feed port 5. The adjusting mounting seat 8 is connected to an air nozzle 10 aimed at the chain 2 and the silo feed port 5 through an air pipe 9, and the blowing of the air nozzle 10 is controlled by the connected air valve. The adjusting mounting seat 8 can adjust the installation angle of the air pipe 9, that is, the position of the air nozzle 10.
[0021] Embodiment 2:
[0022] like Figure 1-2As shown, as a preferred embodiment of the above embodiment, support bars 4 with a downwardly concave middle portion are arranged at intervals at the top of the silo feed port 5. By providing the support bars 4, the scraper 3 of the device will not scratch the edge of the top of the silo feed port 5 during movement, thereby avoiding affecting the normal operation of material transportation in the trough. A gate plate 6 is provided below the support bar 4 on one side of the silo feed port 5. By providing the gate plate 6, the device can further facilitate the control of the switch feeding of the silo feed port 5. Support guide wheels 7 adapted to the bottom surface of the gate plate 6 are arranged at intervals in the silo feed port 5. By providing the support guide wheels 7, the device can support and guide the sliding of the gate plate 6, making its sliding process smoother.
[0023] The specific working principle of this utility model:
[0024] When the device is used, the scraper 1 is started and the air valve is opened, the air nozzle 10 starts to blow air, the chain 2 in the material trough of the scraper 1 starts to move and drives the scraper 3 to start feeding, when the scraper 3 passes the upper end of the silo feed port 5, the conveyed material particles will fall into the silo feed port 5, at this time, the material particles attached to the chain 2 will also be blown out by the air nozzle 10 at the upper end of the chain 2, and fall into the silo feed port 5 together. The utility model adjusts the settings of the mounting seat 8, the air pipe 9, the air nozzle 10 and other structures, so that the device can use the air nozzle 10 to aim at the chain 2, blow off the material particles attached thereto, and effectively prevent this part of the material from being brought into other silos along with the chain 2, resulting in material congestion.
