[0026] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0028] The present invention discloses a buried scraper conveyor, referring to Figure 1 and Figure 2 A scraper conveyor includes a housing 6, a conveying crawler 5 is arranged in the housing 6, and a driving chain 1 is arranged in the middle of the conveying crawler 5. A plurality of scrapers 2 are detachably mounted on the driving chain 1, and the scrapers 2 are driven by the driving chain 1 to move along the conveying crawler 5, thereby realizing the transportation of materials.

[0029] Specifically, refer to Figure 2 and Figure 3 The drive chain 1 includes a plurality of chain units 11, each of which includes a middle chain block 111 and side chain blocks 112 arranged on both sides of the middle chain block 111, and the side chain blocks 112 and the middle chain block 111 are connected by a pin. An embedded scraper 2 is installed on some of the chain units 11, and an installation groove 21 is provided in the middle of the embedded scraper 2. The middle chain block 111 is inserted into the installation groove 21 to achieve the connection between the embedded scraper 2 and the middle chain block 111. After the embedded scraper 2 is installed, the embedded scraper 2 extends from both sides of the middle chain block 111, that is, the conveyor of the present application only needs to be provided with one drive chain 1, which can reduce the space occupied by the drive chain 1.

[0030] Reference Figure 3In order to achieve a stable connection between the buried scraper 2 and the chain unit 11, a plurality of mounting posts 113 are fixed on the upper surface of the middle chain block 111, and a fixing plate 22 is provided on both sides of the buried scraper 2, and a through hole is provided on the fixing plate 22. When the middle chain block 111 is plugged into the mounting groove 21 on the buried scraper 2, there are mounting posts 113 on both sides of the buried scraper 2, and the plurality of mounting posts 113 pass through the plurality of through holes one by one, and the detachable connection between the buried scraper 2 and the chain unit 11 can be achieved through a nut.

[0031] Reference Figure 3 , each buried scraper 2 is also provided with multiple protective plates 3. In the embodiment of the present application, four protective plates 3 are provided on each buried scraper 2, and two protective plates 3 are respectively provided on each side surface of the buried scraper 2; when the buried scraper 2 is installed to the drive chain 1, the two protective plates 3 on each side of the buried scraper 2 are respectively located on both sides of the drive chain 1.

[0032] Further, see Figure 2 and Figure 3 The protective plates 3 arranged on the same side of the drive chain 1 on two adjacent buried scrapers 2 are in contact with each other, so that the drive chain 1 is surrounded by the protective plates 3, reducing the contact between the material and the drive chain 1, thereby reducing the occurrence of jamming of the drive chain 1.

[0033] In a preferred embodiment, reference Figure 3 The protective plate 3 and the buried scraper plate 2 are detachably connected. Specifically, a card slot 23 is provided at the connection between the buried scraper plate 2 and the protective plate 3. Card blocks 31 are provided on both sides of one end of the protective plate 3 close to the conveyor belt 5. The card block 31 and the protective plate 3 are integrally formed. When the protective plate 3 and the buried scraper plate 2 are connected, one end of the protective plate 3 and the card block 31 are both inserted into the card slot 23.

[0034] At the same time, refer to Figure 3 A threaded half hole 311 is formed through the block 31, and a threaded half groove 24 is formed on the side wall of the scraper plate 2 located on the side of the slot 23. When the protective plate 3 is plugged into the slot 23, the threaded half hole 311 and the threaded half groove 24 form a complete threaded circular hole. By threading the locking pin 4 in the threaded half hole 311 and the threaded half groove 24, the scraper plate 2 and the protective plate 3 can be detachably connected.

[0035] Reference Figure 1 Both ends of the shell 6 are provided with expansion chambers 61. When the protective plate 3 runs to the end of the conveyor belt 5 and moves to the bottom of the conveyor belt 5 as the drive chain 1 rotates, the expansion chamber 61 can provide a rotation space for the protective plate 3, thereby ensuring the normal operation of the conveyor.

[0036] In another embodiment, referring to Figure 2 and Figure 4, multiple flexible belts 51 are fixed on the conveyor crawler 5, and a long groove 32 is opened on the bottom wall of each protective plate 3 along the extension direction of the protective plate 3. Each flexible belt 51 is correspondingly inserted into a long groove 32, and the side wall of the long groove 32 is polished. The flexible belt 51 is made of a material with low friction, so that when the protective plate 3 moves along the flexible belt 51, the friction between the two is small. By setting the flexible belt 51 and the long groove 32, the gap between the protective plate 3 and the conveyor crawler 5 can be closed, the material and the drive chain 1 are better isolated, and the occurrence of jams is reduced.

[0037] Reference Figure 1 and Figure 2 Two feed ports 62 are provided on the shell 6, and the feed ports 62 are respectively provided on both sides of the drive chain 1, so that when the conveyor of the present application feeds through the feed ports 62, the materials can directly fall to both sides of the protective plate 3, reducing the contact between the materials and the drive chain 1.

[0038] The protective plate 3 of the conveyor of the present application can be detachably installed on the buried scraper 2. When transporting materials that are likely to cause the drive chain 1 to get stuck, the protective plate 3 can be installed on the buried scraper 2, and material can be fed from the feed ports 62 on both sides of the drive chain 1, with the feed amount not exceeding the height of the protective plate 3, thereby realizing the transportation of materials; when transporting materials that are not likely to get stuck in the drive chain 1, the protective plate 3 can be removed, thereby increasing the transportation capacity of the buried scraper 2 conveyor itself and improving the transportation efficiency.

[0039] In order to facilitate the installation and removal of the protection plate 3, the top plate of the shell 6 can be opened to facilitate the maintenance and repair of the internal structure of the shell 6.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
