Description

Technical Field

[0001] This utility model relates to the field of transmission technology for medium-speed conveyors, and in particular to a rolling conveyor structure for medium-speed conveyors. Background Technology

[0002] Sugarcane bagasse is a major byproduct of the sugarcane sugar industry. It is the fibrous residue of sugarcane stalks after crushing and extracting juice. It is a type of agricultural solid waste and also a renewable resource. One ton of sugarcane bagasse is produced for every ton of sugar produced. Sugarcane bagasse has a relatively high total cellulose content, generally 50%–55%, slightly lower than wood but higher than rice straw; its hemicellulose content is 26%–30%, higher than coniferous trees (such as pine) and close to or exceeding broadleaf trees (such as birch); its lignin content is moderate, around 20%, lower than wood but higher than rice straw. Therefore, sugarcane bagasse fiber is relatively easy to cook; its ash content (bagasse ash) is higher than wood, around 4%, but lower than rice straw.

[0003] like Figure 4 As shown, in the production process, a medium-sized conveyor is usually used to collect and transport sugarcane bagasse. The existing medium-sized conveyor's transmission method usually involves the crossbeam directly resting on the nylon pad 16 for hard friction, which causes the nylon pad 16 to wear out quickly, requiring frequent shutdowns for replacement. Moreover, replacement is difficult, requiring the entire transmission mechanism to be disassembled for replacement, resulting in a large workload and high labor intensity for maintenance. It also wears down the crossbeam. If replacement is needed, it requires a lot of money and time, resulting in high maintenance costs. If it is not replaced in time after wear, the conveyor chain will become loose, the conveying effect will deteriorate, and thus affect production. Utility Model Content

[0004] The technical problem to be solved by this utility model is to address the above-mentioned shortcomings of the prior art by providing a rolling conveyor structure for a medium-sized conveyor, which can reduce the wear of the crossbeam and avoid the occurrence of failures while ensuring the smooth operation of the transmission mechanism.

The nylon roller is arranged on the slide rail. The inner wall of the medium-sized conveyor is provided with a protective device for covering the nylon roller.

[0006] As a further improvement, the protective device comprises a baffle, a rotating shaft and a limiting support for limiting the position of the baffle, the baffle is rotatably installed on the inner wall of the middle conveying machine through the rotating shaft, and the limiting support is installed on the cross beam below the baffle.

[0007] Further, the highest point of the limiting support is lower than the installation height of the rotating shaft.

[0008] Further, the cross beam is provided with magnets on both sides, and the baffle is adsorbed with the magnets after being turned over.

[0009] Further, a pin shaft is arranged outside the nylon roller, and a roller retaining ring is arranged on the pin shaft.

[0010] Further, the pin shaft comprises a mounting shaft and a supporting shaft, one end of the mounting shaft is connected with the cross beam, the other end of the mounting shaft is rotatably connected with the supporting shaft through a bearing, and a sealing end cover is arranged at the connection position of the mounting shaft and the supporting shaft.

[0011] Further, a lubricating channel is arranged on the supporting shaft, one end of the lubricating channel is communicated with the mounting hole of the bearing, and the other end is provided with an oil filling nozzle.
