Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, and more specifically, to a conveying device. Background Technology

[0002] Scraper conveyors, as a traditional material handling device, work by using a chain to drive a series of scrapers fixed to it. The scrapers contact the material and propel it forward, achieving continuous material transport. Compared to other types of conveying equipment such as belt conveyors and screw conveyors, scraper conveyors demonstrate better applicability and reliability when handling bulk materials, high-moisture materials, and fragile materials. However, the design of traditional scraper conveyors has certain limitations, especially in the way the scrapers are fixed.

[0003] In existing scraper conveyors, scrapers are typically permanently connected to the chain directly via welding or bolting, forming a rigid conveying system. While this design ensures the stability of the scrapers during conveying, in practical applications, due to prolonged exposure to material friction and impact, the scrapers are prone to wear and damage. Once a scraper malfunctions, it not only affects the overall efficiency of the conveying system but also makes replacing the damaged scraper complex and time-consuming due to the fixed connection between the scraper and the chain. Sometimes, it even requires stopping the machine and disassembling the entire chain to complete the replacement, undoubtedly increasing equipment maintenance costs and downtime, and reducing the production line's operating rate.

[0028] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] See also Figures 1 to 5 As shown, this utility model provides a conveying device, which includes: a conveying pipe 10 having an installation cavity; a conveying mechanism including a drive unit, a first transmission chain 20 and a second transmission chain 30, both the first transmission chain 20 and the second transmission chain 30 being installed in the installation cavity, the first transmission chain 20 and the second transmission chain 30 being spaced apart along a first direction, the drive unit being able to drive the first transmission chain 20 and the second transmission chain 30 to rotate synchronously; and a plurality of scraper assemblies 40, the plurality of scraper assemblies 40 being arranged spaced apart along the circumference of the first transmission chain 20, for scraping... The plate assembly 40 includes a mounting base 41 and a scraper 42. One end of the mounting base 41 is fixedly connected to the first drive chain 20, and the other end of the mounting base 41 is fixedly connected to the second drive chain 30. The mounting base 41 is provided with a slot 411. The scraper 42 includes an insertion section 421 and a scraping section 422 connected to each other. The insertion section 421 is inserted into the slot 411 and is detachably connected to the mounting base 41 by bolts. The scraping section 422 is located outside the slot 411. When the insertion section 421 is inserted into the slot 411, the scraping section 422 and the mounting base 41 abut against each other at their respective ends.

[0030] In this embodiment, the drive unit drives the first transmission chain 20 and the second transmission chain 30 to rotate synchronously, so that the first transmission chain 20 and the second transmission chain 30 move at the same speed. The two ends of the mounting base 41 are fixedly connected to the first transmission chain 20 and the second transmission chain 30 respectively, ensuring that the scraper assembly 40 moves with the movement of the first transmission chain 20 and the second transmission chain 30. When the drive unit starts and drives the first transmission chain 20 and the second transmission chain 30 to rotate synchronously, it can drive multiple scraper assemblies 40 to move accordingly. At this time, the bottom of the scraper 42, which moves to the bottom of the mounting cavity, is in contact with the bottom wall of the mounting cavity, thereby pushing the material in the conveying pipe 10 forward. With the cyclical movement of the first transmission chain 20 and the second transmission chain 30, the scraper 42 can transport the material from one end of the conveying pipe 10 to the other end, realizing the material conveying function of the entire device.

[0031] The scraper assembly 40 includes a mounting base 41 and a scraper 42. The mounting base 41 and scraper 42 are separate structures, making the scraper 42 an independent and replaceable module. When the scraper 42 is worn or damaged, it is not necessary to replace the entire scraper assembly 40; only the scraper 42 needs to be replaced, greatly improving maintenance efficiency and reducing maintenance costs. The insertion section 421 can be inserted into the slot 411 of the mounting base 41 and is detachably connected to the mounting base 41 by bolts. This ensures the stability of the scraper assembly 40 and facilitates the replacement and maintenance of the scraper 42. This bolted connection method allows for the replacement of the scraper 42 without complex tools, which can be completed by operators in a short time, significantly improving the efficiency and convenience of maintenance work. When the insertion section 421 is placed in the slot 411, the scraping section 422 and the mounting base 41 abut against each other at their respective ends, ensuring close contact between the scraper 42 and the mounting base 41 during operation, forming a stable structure. This also facilitates positioning of the scraper 42 during installation and replacement, reducing the difficulty of replacing the scraper 42.

[0032] See also Figures 1 to 5 As shown, in one embodiment of the present invention, the insertion segment 421 is adapted to the slot 411. Along the thickness direction of the mounting base 41, the slot 411 has a first sidewall and a second sidewall that are arranged opposite to each other. The end of the first sidewall away from the second transmission chain 30 is provided with at least one first connecting hole 412, and the end of the second sidewall away from the second transmission chain 30 is provided with at least one second connecting hole 413. At least one first connecting hole 412 and at least one second connecting hole 413 are arranged in a one-to-one correspondence. The insertion segment 421 is provided with the same number of third connecting holes 4211 as the number of first connecting holes 412. When the insertion segment 421 is inserted into the slot 411, a third connecting hole 4211 is provided between the corresponding first connecting holes 412 and second connecting holes 413, and the centers of the corresponding first connecting holes 412, second connecting holes 413 and third connecting holes 4211 are collinear.

[0033] In this embodiment, the conveying device also includes bolts in the same number as the first connecting holes 412. The bolts are arranged one-to-one with the first connecting holes 412. When connecting the scraper 42 and the mounting base 41, the bolts are passed through the corresponding first connecting holes 412, second connecting holes 413 and third connecting holes 4211 and then locked by nuts, thereby realizing the connection between the scraper 42 and the mounting base 41.

[0034] The centers of the first connecting hole 412, the second connecting hole 413, and the third connecting hole 4211 are collinear, which allows the connection between the scraper 42 and the mounting base 41 to be quickly achieved by bolts. This not only accelerates the connection speed between the scraper 42 and the mounting base 41, but also makes it convenient and efficient to disassemble or replace the scraper 42, greatly shortening maintenance time and reducing economic losses caused by downtime.

[0035] See also Figures 1 to 5 As shown, in one embodiment of the present invention, the scraper 42 further includes a bending section 423. One end of the bending section 423 is connected to the end of the scraping section 422 away from the mounting base 41, and the other end of the bending section 423 extends away from the scraping section 422 along the thickness direction of the mounting base 41. The bending section 423 and the scraping section 422 are set at an angle, and the value of the angle α between the bending section 423 and the scraping section 422 is in the range of 100°≤α≤130°.

[0036] In this embodiment, the bend section 423 increases the contact area between the scraper 42 and the material, improving the material conveying efficiency. If the conveying pipe 10 has a bend, a traditional straight scraper may not be able to fully contact the pipe wall, causing material to accumulate at the corner. The bend section 423 can fit the bend of the conveying pipe 10, reducing material retention and accumulation in complex paths, and ensuring the continuity and stability of material conveying.

[0037] See also Figures 1 to 5 As shown, in one embodiment of the present invention, the conveying pipe 10 is Z-shaped and includes a first pipe section 11, an inclined pipe section 12, and a second pipe section 13 that are connected to each other. The first pipe section 11 and the second pipe section 13 are spaced apart in the horizontal direction and both extend in the horizontal direction. The first pipe section 11 and the second pipe section 13 are spaced apart in the vertical direction and are parallel to each other. One end of the inclined pipe section 12 is connected to the first pipe section 11, and the other end of the inclined pipe section 12 is connected to the second pipe section 13. The first transmission chain 20 and the second transmission chain 30 both extend from the first pipe section 11 through the inclined pipe section 12 to the second pipe section 13.

[0038] In this embodiment, the first drive chain 20 and the second drive chain 30 run through the entire conveying pipe 10, extending from the first pipe section 11 through the inclined pipe section 12 to the second pipe section 13. This ensures efficient material conveying. Through the cooperation of the conveying mechanism and the scraper assembly 40, materials can be conveyed from the second pipe section 13 through the inclined pipe section 12 back to the first pipe section 11. The conveying pipe 10 is Z-shaped, providing more layout options for the production line. It can achieve efficient material conveying within a limited space. This layout optimization helps reduce the floor space occupied by the production line and improves space utilization efficiency.

[0039] See also Figures 1 to 5 As shown, in one embodiment of the present invention, the length of the first pipe segment 11 is L1, the length of the second pipe segment 13 is L2, and the length of the inclined pipe segment 12 is L3. The length relationship of the three segments satisfies: L3 = (L1 + L2) / 2.

[0040] The above setup reduces energy consumption during the entire material transport process, reduces the floor space occupied by the transport equipment, and improves space utilization.

[0041] See also Figures 1 to 5 As shown, in one embodiment of the present invention, the conveying device further includes a support frame 50. The support frame 50 includes a support plate 51 and a support leg 52 disposed at the bottom of the support plate 51. The support plate 51 can support the end of the first pipe section 11 away from the second pipe section 13. The support plate 51 is provided with a through hole. The end of the first pipe section 11 away from the second pipe section 13 is provided with a discharge pipe 60, which passes through the through hole.

[0042] In this embodiment, the support frame 50 provides a stable support point for the first pipe segment 11 of the conveying pipe 10, helping to maintain the structural stability of the entire conveying device and preventing the first pipe segment 11 from sagging or deforming due to the weight of the conveyed material or dynamic loads. The through holes on the support plate 51 allow the discharge pipe 60 to pass directly through, simplifying the installation process of the conveying device and facilitating subsequent maintenance and repair. During maintenance, the through holes also make it easy to disassemble and replace the discharge pipe 60 without disassembling the entire support frame 50.

[0043] See also Figures 1 to 5 As shown, in one embodiment of the present invention, there are four support legs 52, which are respectively arranged at the four corners of the support plate 51 to support the support plate 51.

[0044] See also Figures 1 to 5As shown, in one embodiment of the present invention, the drive unit includes a drive motor, a drive shaft, a first driven shaft 70, and two second driven shafts. The drive shaft is installed inside the first pipe section 11 and located at the end of the first pipe section 11 away from the second pipe section 13.
