Description

Technical Field

[0001] The present application relates to the technical field of conveying devices, and in particular to a scraper conveyor. Background Art

[0002] A conveyor is a material handling machine that continuously transports materials along a certain route. It is also called a continuous conveyor. It can perform horizontal, inclined and vertical transportation. It is widely used due to its advantages such as large conveying capacity and long conveying distance.

[0003] At present, the lifting conveyors for lifting and conveying materials generally include high-angle conveyors and bucket elevators. Among them, the high-angle conveyor can be tilted and lifted horizontally and then output horizontally, but it occupies a large area and the tilt angle should not be too large. Too large a tilt angle will increase the material falling during the conveying process, causing the fallen materials to generate dust, pollute the air, and affect the surrounding environment and personnel health. At the same time, the falling of materials will also lead to lower conveying efficiency. Although the bucket elevator occupies a small area and uses a closed shell, it only has the ability to lift materials and has no horizontal lateral conveying ability. Therefore, when using it, it needs to be connected to other conveyors for horizontal transition conveying, which makes the cost high. Utility Model Content

[0048] See also Figures 1 to 3 A scraper conveyor provided in an embodiment of the present application includes: a closed shell 10 and a conveying component 20.

[0049] The sealed housing 10 includes: a lower horizontal section 11 , a vertical section 12 and an upper horizontal section 13 ; the upper end of the vertical section 12 is connected to the upper horizontal section 13 ; the lower end of the vertical section 12 is connected to the lower horizontal section 11 .

[0050] In this embodiment, the closed housing 10 can be used for transporting materials therein. In application, a feed port 104 and a discharge port 105 are provided on the closed housing 10. Except for the feed port 104 and the discharge port 105, other positions are in a closed state to prevent dust generated during material transmission or leakage of the material itself from polluting the environment.

[0051] In this embodiment, the vertical section 12 is vertically arranged, which can effectively reduce the size of the lateral space occupied by the entire sealed housing 10 .

[0052] It should be noted that the end of the lower horizontal section 11 away from the vertical section 12 and the end of the upper horizontal section 13 away from the vertical section 12 can be closed by the housing 106. In practical applications, the lower horizontal section 11 and / or the upper horizontal section 13 can be spliced ​​and assembled to a desired length, and then closed by the housing 106.

[0053] The conveying assembly 20 includes: a conveying chain 21 and a scraper 22; the conveying chain 21 is arranged in a closed housing 10; a scraper slot 101 arranged along the conveying direction of the conveying chain 21 is arranged in the closed housing 10; the scraper 22 is fixedly connected to the conveying chain 21 and slidably arranged in the scraper slot 101. It should be noted that the scraper 22 includes a plurality of scrapers, which are distributed at intervals on the conveying chain 21; and in this embodiment, the scraper 22 abuts against the slot edge of the scraper slot 101.

[0054] In this embodiment, the conveyor chain 21 can be driven in the sealed housing 10, and drive the scraper 22 to slide along the scraper groove 101 and pass through the lower horizontal section 11, the vertical section 12 and the upper horizontal section 13, so as to drive the material to be transported horizontally and vertically in the scraper groove 101. Among them, by providing the scraper 22 and the scraper groove 101, it is possible to effectively prevent the material from falling during the vertical transportation process, thereby achieving a smoother and more efficient transportation effect.

[0055] The processing technology of the scraper conveyor provided in this embodiment is simple, and only a few parts of the closed shell 10 need to be welded, and no other external conveying mechanism is required, so the manufacturing cost is low.

[0056] In such Figure 2 In the internal structure of the closed shell 10 shown, the closed shell 10 is only provided with a scraper groove 101 on one side of the inner wall. The scraper groove 101 can be set on the lower wall surface of the lower horizontal section 11 and the upper horizontal section 13. The scraper groove 101 in the vertical section 12 is connected with the scraper groove 101 in the lower horizontal section 11 and the upper horizontal section 13, which can meet the material transportation requirements.

[0057] In one embodiment, the inner wall of the closed shell 10 facing the conveying chain 21 is provided with a scraper groove 101, that is, the lower wall and the upper wall of the lower horizontal section 11 and the upper horizontal section 13 can be provided with a scraper groove 101. Similarly, the two wall surfaces facing the conveying chain 21 in the vertical section 12 are also provided with a scraper groove 101, so that the scraper 22 can slide in the scraper groove 101 during the conveying process, and also slide along the scraper groove 101 in the process of the scraper 22 passing through the discharge port 105 and returning to the feed port. On the one hand, the scraper groove 101 can always guide the scraper 22, and on the other hand, it can prevent part of the material adhering to the scraper 22 from moving to the left and right sides of the scraper 22 and contaminating the transmission components such as the conveying chain 21.

[0058] Correspondingly, in one embodiment, the scraper 22 can be configured to have an L-shaped or C-shaped structure in longitudinal section, so that the scraper 22 can better surround the material to push the material, and the scraper 22 can still surround the material in the process of passing through the discharge port 105 and returning to the feed port.

[0059] In one embodiment, the conveying assembly 20 further includes: a plurality of sprockets 23 ; the sprockets 23 are disposed in the sealed housing 10 ; and the conveying chain 21 is transmission-connected to the sprockets 23 .

[0060] Furthermore, the scraper conveyor further comprises a driving motor 30 ; the driving motor 30 is transmission-connected to at least one sprocket wheel 23 via a driving chain 31 , and is used for driving the conveying chain 21 to transport materials.

[0061] That is, in this embodiment, the scraper conveyor drives the conveying chain 21 to convey by driving the sprocket 23 to rotate through the driving motor 30 .

[0062] More specifically, the sprocket 23 connected to the driving chain 11 can be disposed above the discharge port 105 or behind the discharge port 105, which can reduce the possibility of the sprocket 23 being contaminated by the material.

[0063] For more specific examples, see Figures 1 to 8 The sealed housing 10 further includes: a lower bending section 14 and an upper bending section 15 ; the upper end of the vertical section 12 is connected to the upper horizontal section 13 through the upper bending section 15 ; the lower end of the vertical section 12 is connected to the lower horizontal section 11 through the lower bending section 14 .

[0064] In this embodiment, the upper bending section 15 and the lower bending section 14 are both provided with an opening in the vertical direction and an opening in the horizontal direction, so that the vertical section 12 can be connected to the lower horizontal section 11 or the upper horizontal section 13. In addition, the upper bending section 15 and the lower bending section 14 are also provided with a scraper groove 101 inside.

[0065] See also Figure 5 or Figure 8Among the multiple sprockets 23, there are a large sprocket 231 and a small sprocket 232; the large sprocket 231 and the small sprocket 232 are both arranged in the upper bending section 15 and the lower bending section 14, and, in the conveying chain 21 passing through the large sprocket 231 and the small sprocket 232, the small sprocket 232 is located inside the conveying chain 21, and the large sprocket 232 is located outside the conveying chain 21.

[0066] Specifically, the large sprocket 231 and the small sprocket 232 serve as turning guide wheels for the conveyor chain 21 . The large sprocket 231 presses the outer side of the conveyor chain 21 , and the small sprocket 232 presses the inner side of the conveyor chain 21 to enable the conveyor chain 21 to turn in the upper bending section 15 and the lower bending section 14 .

[0067] In the existing bucket elevator, the turning transition position between the bucket elevator and other horizontal conveying mechanisms is prone to jamming, blocking and other conveying problems. In this embodiment, through the scraper groove 101, the scraper 22 and the large sprocket 231 and the small sprocket 232, the material can be smoothly conveyed in the turning area in the closed shell 10, which can effectively improve the conveying efficiency and conveying effect.

[0068] Further, the lower bending position a of the lower bending section 14 is an arc transition structure. Figure 8 The lower bending position b of the upper bending section 15 can also be set as an arc transition structure. In addition, the lower bending position a of the lower bending section 14 and the lower bending position b of the upper bending section 15 are both provided with the above-mentioned scraper groove 101, so that the scraper 22 can better drive the material to pass through when passing by and reduce the situation of unsmooth conveying.

[0069] In one embodiment, Figure 2 As shown, rollers 24 are provided on both sides of the conveying chain 21 along the width direction; a bracket 102 is provided in the closed housing 10 ; and the rollers 24 can roll and abut against the bracket 102 .

[0070] The cooperation between the bracket 102 and the roller 24 can effectively improve the smoothness of the conveying process of the conveyor chain 21, and the bracket 102 can improve the support for the conveyor chain 21, thereby improving the carrying capacity and conveying effect of the conveyor chain 21.

[0071] Furthermore, a wear-resistant rubber layer 103 is provided on the bracket 102. The wear-resistant rubber layer 103 can extend into the upper bending section 15 and the lower bending section 14. The wear-resistant rubber layer 103 can increase the wear resistance of the conveyor chain 21 and improve its service life.

[0072] In one embodiment, a feed port 104 is disposed on the upper side wall of the lower horizontal section 11 ; a discharge port 105 is disposed on the lower side wall of the upper horizontal section 13 .

[0073] Specifically, the feed port 104 is disposed on the upper side wall of the lower horizontal section 11, which does not affect the installation of the housing 106 and facilitates the entry of materials into the lower horizontal section 11. The discharge port 105 is disposed on the lower side wall of the upper horizontal section 13 to facilitate material discharge.

[0074] In another embodiment, the scraper 22 can be fixedly connected to the conveyor chain 21 by bolts. The bolt fixing method can meet the installation rigidity strength requirements of the scraper 22 on the one hand, and can facilitate the replacement of the scraper 22 on the other hand.

[0075] In application, the bottom of the sealed housing 10 may be provided with feet 107 for supporting and elevating the sealed housing 10 .

[0076] When in use, the drive motor 30 is started, and the drive motor 30 drives the drive chain 31 to transmit so that the sprocket 23 connected to the drive chain 31 rotates counterclockwise, so that the scraper 22 on the upper layer of the conveying chain 21 moves toward the lower horizontal section 11, and the scraper 22 on the upper layer of the conveying chain 21 moves toward the upper horizontal section 13; the material is pushed by the scraper 22 in the scraper groove 101 in the lower horizontal section 11 toward the upper horizontal section 13; in the lower bending section 14, the conveying chain 21 is turned at a right angle of 90 degrees under the cooperation of the large sprocket 231 and the small sprocket 232, so that the scraper 22 makes an arc transition at the lower end bending position a of the lower bending section 14 Under the action, the material is smoothly scraped into the scraper groove 101 of the vertical section 12; the scraper 22 filled with materials turns from horizontal to vertical transportation, pushes the materials upward in the scraper groove 101 of the vertical section 12, and then transports the materials to the upper bending section 15. Since the lower end bending position b of the upper bending section 15 is designed as an eight-shaped arc transition structure, the transition connection between the scraper 22 and the upper bending section 15 is smoother; during the turning process of the scraper 22 in the upper bending section 15, it fits with the lower end bending position b to avoid material leakage; then the scraper 22 smoothly converts the material from vertical transportation to horizontal transportation, realizing continuous output.

[0077] The scraper conveyor provided in the embodiment of the present application has a large conveying capacity, can realize the continuous conveying of a large amount of materials and take into account both horizontal and vertical conveying capabilities. The equipment has a long service life and low manufacturing cost, and has the advantages of high conveying efficiency and good conveying effect.

[0078] The above are only preferred embodiments of the present application and are not intended to limit the present utility model. Although the present application has been described in detail with reference to the examples, those skilled in the art can still modify the technical solutions recorded in the aforementioned examples or make equivalent substitutions for some of the technical features therein.
