Description

Technical Field

[0001] This utility model relates to the technical field of vertical grain conveying, and in particular to the technical field of a scraper chain for vertical grain conveying with short pitch. Background Technology

[0002] Vertical scraper bucket elevators are mainly used in ports and wharves for unloading bulk grain from ships. They continuously lift grain out of the ship's hold and unload it onto the boom or frame, then transport it to the main conveyor on the shore. The working principle is that the grain enters from the bottom feed inlet, is pushed upward along the trough by the moving scraper, and after reaching the top, the grain is discharged from the middle of the casing under the action of gravity.

[0003] The scraper plates of existing vertical scraper elevators are generally made of thick steel plates (thin steel plates are prone to deformation), but thick steel plates are heavy and not conducive to the overall weight reduction of the device. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a short-pitch scraper chain for vertically conveying grain, which can help to reduce the weight of the overall device and reduce the lifting load.

[0005] To achieve the above objectives, this utility model proposes a short-pitch vertical grain conveying scraper chain, including a conveying chain, several scrapers I and several scrapers II. The conveying chain is provided with scrapers I and scrapers II spaced apart along its direction of movement, with at least one scraper I spaced between every two scrapers II. The scraper I is provided with several hollow areas.

[0006] Preferably, at least three scraper blades I are spaced apart between every two scraper blades II.

[0007] Preferably, the conveyor chain is a short-pitch conveyor chain.

[0008] Preferably, the pitch of the conveyor chain is 80~100mm.

[0009] Preferably, scraper I and scraper II are provided with clearance grooves at one end facing the conveyor chain, and scraper I and scraper II are provided with fixing plates on both sides of the clearance grooves, and the fixing plates are fixedly connected to the corresponding outer chain plates of the conveyor chain.

[0010] Preferably, the hollow area includes a through hole, a mesh plate, and a blocking step. The lower end of the through hole is provided with a blocking step. The mesh plate is located inside the through hole and rests on the blocking step. The mesh plate is fixedly connected to the blocking step by bolts.

[0011] The beneficial effects of this utility model are as follows: By arranging scraper I and scraper II at intervals along the direction of movement on the conveyor chain, with at least one scraper I between every two scraper II, and by providing several hollow areas on scraper I, the weight of scraper I is reduced; compared with the prior art, this utility model can help to lighten the overall device and reduce the lifting load.

[0012] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

[0015] See Figure 1 , Figure 2 This utility model discloses a scraper chain for vertically conveying grain with a short pitch, comprising a conveyor chain 1, a plurality of scrapers I2 and a plurality of scrapers II3. The conveyor chain 1 is provided with scrapers I2 and scrapers II3 at intervals along its direction of movement, and at least one scraper I2 is spaced between every two scrapers II3. The scrapers I2 are provided with a plurality of hollow areas 4.

[0016] There must be at least three scraper blades I2 between every two scraper blades II3.

[0017] The conveyor chain 1 is a short-pitch conveyor chain. When the short-pitch conveyor chain meshes with the head pulley, the impact is smaller, the operation is smoother, and the transmission efficiency is higher.

[0018] The pitch of the conveyor chain 1 is 80~100mm.

[0019] Both scraper I2 and scraper II3 have clearance grooves 5 at one end facing the conveyor chain 1. Both scraper I2 and scraper II3 have fixing plates 6 on both sides of the clearance grooves 5. The fixing plates 6 are fixedly connected to the corresponding outer chain plates 7 of the conveyor chain 1.

[0020] The fixed plate 6 is integrally formed and fixedly connected with the corresponding outer chain plate 7, and the scraper I2 and scraper II3 are evenly fixedly connected with the corresponding scraper I2 and scraper II3 through a number of bolt pairs 8.

[0021] The hollow area 4 includes a through hole 41, a mesh plate 42, and a blocking step 43. The lower end of the through hole 41 is provided with a blocking step 43. The mesh plate 42 is located in the through hole 41 and rests on the blocking step 43. The mesh plate 42 is fixedly connected to the blocking step 43 by bolts 44. The appropriate mesh size of the mesh plate 42 can be selected for assembly according to the grain being transported, which effectively reduces the inventory of components.

[0022] The working process of this utility model: This utility model discloses a short-pitch vertical grain conveying scraper chain. During operation, scrapers I2 and II3 are spaced along the direction of movement on the conveying chain 1, with at least one scraper I2 between every two scrapers II3. The scraper I2 is provided with several hollow areas 4 to reduce its weight. Compared with the prior art, this can help to make the overall device lighter and reduce the lifting load.

[0023] For scraper elevators with the same conveying capacity, using a short-pitch scraper chain can appropriately increase the speed of the scraper chain, thereby increasing the conveying capacity of the scraper elevator.

[0024] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
