Description

Technical Field

[0001] The utility model relates to the technical field of scraper chains, in particular to a scraper member of a scraper chain. Background Technique

[0002] A scraper chain is a mechanical device for material transportation, which is widely used in industries such as mines, metallurgy, and construction. It consists of a chain and scrapers. Through the movement of the chain, the scrapers can transport materials from one end to the other. The chain is composed of multiple chain links, usually made of steel materials, with strength and wear resistance. The scrapers are fixed on the chain, and their shapes and sizes are designed according to the material characteristics, and they can effectively shovel and transport materials. With the progress of technology, the materials and designs of scraper chains are constantly improved, developing towards higher wear resistance and lower failure rates.

[0003] During the use of the scraper chain, it can not only act as a tool for material transmission, but also realize its own functions by shoveling and pushing materials. In the existing scraper chain, the scraper member is fixed during use and only serves one of the functions, resulting in greater limitations in the use of the scraper chain and greatly reducing the working performance of the tube plate chain.

[0004] Therefore, it is urgently necessary to provide a scraper member of a scraper chain to solve the above problems. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the above-mentioned disadvantages of the prior art and provide a scraper member of a scraper chain.

[0006] To solve the above technical problem, a technical solution adopted by the utility model is: to provide a scraper member of a scraper chain, including a pin shaft, both ends of the pin shaft are movably connected with chain links, and an adjusting mechanism is installed at one end of the pin shaft;

[0007] Two scraper mechanisms are installed on the outer wall of the adjusting mechanism, and a connecting mechanism is installed on the top of both scraper mechanisms.

[0008] The utility model is further arranged as: the adjusting mechanism includes a wide gear fixedly connected to the outer wall of the pin shaft, a threaded rod is rotatably connected to one side of one of the chain links, a narrow gear is fixedly connected to the outer wall of the threaded rod, a corner knob is fixedly connected to the other end of the threaded rod, fixed sleeves are fixedly connected to both ends of the pin shaft, and the narrow gear meshes with the wide gear.

[0009] Through the above technical solution, during use, multiple such pin shafts and chain links are spliced. An adjusting mechanism is installed on one of the chain links as the main driving part, and the others rotate following one of the chain links. After installation, the operator can use a wrench to rotate the angular knob. During the rotation, the threaded rod connected to the angular knob will embed into the chain link. Since the narrow gear meshes with the wide gear, at this time, the narrow gear will move as the threaded rod enters, so as to achieve limiting and prevent loosening after adjustment. Furthermore, the wide gear will rotate, so that the device obtains a total driving force, facilitating the subsequent steps.

[0010] The present utility model is further configured as: the scraper mechanism includes a scraper body fixedly connected to the outer wall of the fixed sleeve. Plate grooves are formed on both sides of the scraper body. Two first springs are fixedly connected inside each of the two plate grooves. The other ends of the multiple first springs are fixedly connected with auxiliary plates, and the outer walls of the auxiliary plates are respectively slidably connected to the corresponding plate grooves.

[0011] Through the above technical solution, after the wide gear rotates, it will drive the scraper body to rotate, enabling the vertically placed scraper body to change its direction. Therefore, the function of the scraper part can be correspondingly changed. It can change from scraping and conveying materials in the pipeline to transporting materials, and the horizontal end area becomes larger. At this time, with the rotation, the multiple first springs inside it are released and can extrude the auxiliary plates towards the outer wall until the auxiliary plates abut against another auxiliary plate, and this movement process terminates. When changing the direction, the auxiliary plates will form a certain extrusion force with the cargo transportation channel until they are compressed into the plate grooves. Furthermore, the scraper part can be improved, its function is gradually expanded, and its applicability is improved.

[0012] The present utility model is further configured as: the connecting mechanism includes a first fixing seat fixedly connected to the top of the scraper body. A metal strip is fixedly connected inside the first fixing seat. The other end of the metal strip is fixedly connected with a second fixing seat. Two first fixing rings are fixedly connected to the outer wall of the fixed sleeve. Two second springs are fixedly connected to the outer walls of the two first fixing rings. The other ends of the two second springs are fixedly connected with a second fixing ring. The second fixing seat is fixed to the lower surface of another scraper body. The metal strip penetrates through the bottom edge of the auxiliary plate, and the two second fixing rings are both fixed to the bottom of another scraper body.

[0013] Through the above technical solution, when the scraper part is in the vertical state, the movement state of the device at this time will straighten the second spring between the first fixing ring and the second fixing ring and release the maximum elastic potential energy. When switching from the horizontal to the vertical state, the metal strip between the first fixing seat and the second fixing seat will form a certain pulling force, causing another scraper body to form the same state. When restoring, due to the elastic potential energy of the spring, the scraper body obtains power and restores to the horizontal state.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. By designing a simple adjustment mechanism, a scraper mechanism, and a connection mechanism, the present utility model enables the scraper to be converted according to requirements during the use of the scraper chain. By manually rotating, the horizontal and vertical directions of the plate body can be adjusted, thus greatly improving the working performance of the scraper.

[0016] 2. By designing a simple scraper mechanism and a connection mechanism, the present utility model can replace the scraper in the use state by manual rotation, and can automatically reset when reset, increasing the automatic recovery effect of the scraper. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following describes in detail the preferred embodiments of the present utility model with reference to the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the present utility model more clearly defined.

[0024] Please refer to Figures 1 - 5, A scraper member of a scraper chain, including a pin shaft 1. Both ends of the pin shaft 1 are movably connected with link joints 2. One end of the pin shaft 1 is provided with an adjusting mechanism 3. The adjusting mechanism 3 includes a wide gear 301 fixedly connected to the outer wall of the pin shaft 1. One side of one of the link joints 2 is rotatably connected with a threaded rod 302. A narrow gear 303 is fixedly connected to the outer wall of the threaded rod 302. The other end of the threaded rod 302 is fixedly connected with an angular knob 304. Fixed sleeves 305 are fixedly connected to both ends of the pin shaft 1. The narrow gear 303 meshes with the wide gear 301. When in use, a plurality of pin shafts 1 and link joints 2 are spliced. An adjusting mechanism 3 is installed on one of the link joints 2 as the main driving part, and the others rotate following one of the link joints 2. After installation, the operator can use a wrench to rotate the angular knob 304. During the rotation, the threaded rod 302 connected to the angular knob 304 will embed into the link joint 2. Since the narrow gear 303 meshes with the wide gear 301, at this time, the narrow gear 303 will move along with the entry of the threaded rod 302, so as to achieve limit and avoid loosening after adjustment. Furthermore, the wide gear 301 will rotate, so that the device obtains a total driving force, which is convenient for the subsequent steps;

[0025] As Figure 3 shown, two scraper mechanisms 4 are installed on the outer wall of the adjusting mechanism 3. The scraper mechanism 4 includes a scraper body 401 fixedly connected to the outer wall of the fixed sleeve 305. Plate grooves 402 are opened on both sides of the scraper body 401. Two first springs 403 are fixedly connected inside each of the two plate grooves 402. The other ends of the plurality of first springs 403 are all fixedly connected with auxiliary plates 404. The outer walls of the auxiliary plates 404 are respectively slidably connected with the corresponding plate grooves 402. When the wide gear 301 rotates, it will drive the scraper body 401 to rotate, and the vertically placed scraper body 401 can change its direction. Therefore, the function of the scraper member can be correspondingly changed at this time. It can change from scraping and conveying materials in the pipeline to transporting materials, and the lateral end area becomes larger. At this time, with the rotation, the plurality of first springs 403 inside it are released and can squeeze the auxiliary plates 404 towards the outer wall until the auxiliary plates 404 abut against another auxiliary plate 404, and this movement process terminates. When the direction is replaced, the auxiliary plates 404 will form a certain extrusion force with the cargo transportation channel until they are compressed into the plate grooves 402. Furthermore, the scraper member can be improved, its function is gradually expanded, and its applicability is improved;

[0026] As Figure 5As shown, the tops of the two scraper mechanisms 4 are both installed with a connecting mechanism 5, which includes a first fixing seat 501 fixedly connected to the top of the scraper body 401, a metal strip 502 fixedly connected inside the first fixing seat 501, and a second fixing seat 503 fixedly connected at the other end of the metal strip 502, two first fixing rings 504 fixedly connected to the outer wall of the fixing sleeve 305, second springs 505 fixedly connected to the outer walls of the two first fixing rings 504, and second fixing rings 506 fixedly connected at the other ends of the two second springs 505, the second fixing seat 503 is fixed to the lower surface of the other scraper body 401, and the metal strip 502 is fixedly connected to the inner wall of the first fixing seat 501. The two second fixing rings 506 are fixed to the bottom of the other scraper body 401, which runs through the bottom edge of the auxiliary plate 404. When the scraper member is kept vertical, the movement state of the device will straighten the second spring 505 between the first fixing ring 504 and the second fixing ring 506 and release the maximum elastic potential energy. When switching from horizontal to vertical, the metal strip 502 between the first fixing seat 501 and the second fixing seat 503 will form a certain pulling force, so that the other scraper body 401 forms the same state. When restoring, due to the elastic potential energy of the spring, the scraper body 401 obtains power and restores the horizontal state.

[0027] When the utility model is in use, multiple pin shafts 1 and chain links 2 are spliced, and an adjustment mechanism 3 is installed on one of the chain links 2 as a main driving member, and the rest rotate with one of the chain links 2. After installation, the operator can use a wrench to rotate the angle knob 304. During the rotation process, the threaded rod 302 connected to the angle knob 304 will be embedded in the chain link 2. At this time, the narrow gear 303 will move with the entry of the threaded rod 302, thereby driving the scraper body 401 to rotate, allowing the scraper body 401 in a vertical state to change direction, and multiple first springs 403 inside it The scraper member 404 is released and can be pressed toward the outer wall until the scraper member 404 hits another scraper member 404, and this movement process is terminated. When the scraper member remains vertical, the movement state of the device will straighten the second spring 505 between the first fixed ring 504 and the second fixed ring 506 and release the maximum elastic potential energy. When switching from horizontal to vertical, the metal strip 502 between the first fixed seat 501 and the second fixed seat 503 will form a certain pulling force, so that the other scraper body 401 forms the same state. At this point, the scraper member switching process of the scraper chain is completed.
