Description

Technical Field

[0001] This utility model relates to the field of port machinery technology, specifically a bidirectional vertical scraper elevator and ship unloader. Background Technology

[0002] Scraper unloaders are widely used in grain terminals due to their advantages such as high efficiency, energy saving, environmental protection, fully sealed conveying, and low cost. They are gradually replacing intermittent unloading equipment such as gantry cranes and grab unloaders, and have become the main unloading equipment in grain terminals at home and abroad.

[0003] As a core component of the vertical scraper unloader, the vertical scraper elevator is responsible for digging, lifting, and transferring materials from ships. A typical vertical scraper elevator mainly consists of a drive sprocket assembly, tensioning device, tail pulley assembly, chain scrapers, loaded troughs, and unloaded troughs. The chain of a conventional vertical scraper elevator can only run in one direction, and the rotation direction of the drive sprocket is fixed. Therefore, the loaded and unloaded troughs cannot be used interchangeably. The loaded trough transports materials and experiences rapid wear, while the unloaded trough only serves as a return channel for the chain scrapers. When the wear of the loaded trough reaches the point where it must be replaced or scrapped, the unloaded trough remains intact and cannot be utilized, resulting in waste. Furthermore, replacing the troughs of a vertical scraper elevator requires specialized manufacturers and large lifting equipment, making replacement difficult and costly. Therefore, extending the service life of the troughs has become an urgent problem to be solved. Summary of the Invention

[0004] To address the technical problem of short trough life in existing vertical buried scraper elevators, this application proposes a bidirectional vertical buried scraper elevator and ship unloader, thus solving the aforementioned technical problem.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] This utility model provides a bidirectional vertical scraper elevator, comprising: a machine body, the machine body being vertically arranged, and a sprocket scraper device disposed within the machine body; the sprocket scraper device comprising two sets of sprockets respectively disposed at both ends of the machine body and a chain mounted on the sprockets for cyclic rotation, wherein the two segments of the chain on both sides of the sprockets occupy the area within the machine body to form two working grooves, and the bottom of the two working grooves are provided with corresponding feed inlets on two opposite side walls of the machine body; simultaneously, the tooth profiles between adjacent chain teeth of the sprockets are formed along both sides of the circumferential direction of the sprockets to form meshing transmission surfaces that can drive the chain links to rotate, so that the chain can be driven in both forward and reverse rotation of the sprockets; and two sets of lifting baffle devices, both sets of lifting baffle devices being mounted on corresponding side walls of the machine body, each lifting baffle device including a lifting baffle capable of opening and closing the feed inlet.

[0007] Furthermore, one end of the chain link is expanded outward in the width direction to form a fork head that can be pushed by the meshing transmission surface, and the two ends of the fork head are respectively formed with a front meshing surface and a rear meshing surface that can be abutted by the meshing transmission surface.

[0008] Furthermore, the lifting baffle device also includes a vertically arranged electro-hydraulic actuator, which includes a cylinder and a push rod that can extend out of the cylinder. The cylinder is connected to the outer wall of the machine body and is located at the top of the feed inlet. The drive end of the push rod is connected to the lifting baffle.

[0009] Furthermore, a vertical guide rail is also provided on the outer wall of the machine body, the guide rail is arranged at the feed inlet, and the lifting baffle is limited and fitted on the guide rail.

[0010] Furthermore, each link of the chain is equipped with a scraper.

[0011] Furthermore, each tooth of the sprocket forms a vertical surface extending in the radial direction to form the meshing drive surface.

[0012] Furthermore, the chain teeth are provided with mating grooves that accommodate the chain link bodies, and the mating grooves are arranged on the outer peripheral surface of the chain teeth.

[0013] This utility model also provides a ship unloader, including the above-mentioned bidirectional vertical buried scraper elevator.

[0014] Based on the above technical solution, the technical effects that this utility model can achieve are as follows:

[0015] This utility model discloses a bidirectional vertical buried scraper elevator. The tooth profiles between adjacent chain teeth of the sprocket of the sprocket scraper device are formed on both sides of the sprocket circumferential direction, creating meshing transmission surfaces that can drive the chain links to rotate. This allows the sprocket to drive the chain in both forward and reverse directions. At the same time, both working troughs are equipped with independent, self-closing feed ports, allowing both working troughs to transport materials. Compared to the previous situation where only one working trough could transport materials, the machine body's troughs are fully utilized, doubling the overall service life of the troughs and greatly extending the trough replacement cycle of the vertical buried scraper elevator. In addition, in the event of material blockage, the fault can be eliminated by controlling the sprocket to reverse. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] like Figure 1-5As shown, this utility model provides a bidirectional vertical scraper elevator, including a machine body 1, a sprocket scraper device 2, and two sets of lifting baffle devices 3. The sprocket scraper device 2 is installed inside the machine body 1. The sprocket scraper device 2 includes two sets of sprockets 21 respectively disposed at both ends of the machine body 1 and chains 22 mounted on the sprockets 21 that can rotate cyclically. The two chain segments 22 on both sides of the sprockets 21 occupy the area inside the machine body 1 to form two working grooves 11. The bottom of the two working grooves 11 has corresponding inlets on the two opposite side walls of the machine body 1. The feed inlet 12, and at the same time, the tooth profiles between adjacent chain teeth 211 of the sprocket 21 are formed on both sides of the circumferential direction of the sprocket 21, forming meshing transmission surfaces 2111 that can drive the chain links 221 of the chain 22 to rotate. If each chain tooth 211 of the sprocket 21 forms a vertical surface extending in the radial direction to form a meshing transmission surface 2111, the chain 22 can be driven when the sprocket 21 rotates in both directions. The two sets of lifting baffle devices 3 are both mounted on the side wall of the corresponding machine body 1. The lifting baffle device 3 includes a lifting baffle 31 that can open and close the feed inlet 12.

[0027] In this utility model of a bidirectional vertical buried scraper elevator, the feed inlet 12 and the working trough 11 are both symmetrically designed, and the two working troughs 11 on both sides can be used interchangeably, thus doubling the overall service life of the trough. Both sides of the tooth profile of the sprocket 21 can be used as meshing transmission surfaces 2111, thus doubling the service life of the sprocket 21 and the chain 22. During the lifting and conveying of materials, the scraper 223 of the vertical buried scraper elevator often experiences jamming and material blockage due to impurities, fibers, metal parts, etc. in the materials. The bidirectional vertical buried scraper elevator provided by this utility model can eliminate the fault by reversing the sprocket 21 and running the chain 22 in reverse when a material blockage alarm occurs.

[0028] In one specific embodiment of this utility model, one end of the chain link 221 is expanded outward in the width direction to form a fork 222 that can be pushed by the meshing transmission surface 2111. The two ends of the fork 222 are respectively formed with a front meshing surface 2221 and a rear meshing surface 2222 that can be abutted by the meshing transmission surface 2111. When the sprocket 21 rotates forward and backward, the chain teeth 211 of the sprocket 21 can mesh with the fork 222 of the chain link 221, and power can be effectively transmitted in both directions. When the sprocket 21 rotates forward, the meshing transmission surface 2111 on the left side of the tooth profile meshes with the front meshing surface 2221 of the chain link 221, and when the sprocket 21 rotates forward, the meshing transmission surface 2111 on the right side of the tooth profile meshes with the rear meshing surface 2222 of the chain link 221.

[0029] In a specific embodiment of this utility model, the lifting baffle device 3 further includes a vertically arranged electro-hydraulic push rod 32. The electro-hydraulic push rod 32 includes a cylinder 321 and a push rod 322 that can extend out of the cylinder 321. The cylinder 321 is connected to the outer wall of the machine body 1 and is located at the top of the feed inlet 12. The driving end of the push rod 322 is connected to the lifting baffle 31. The lifting baffle 31 is raised and lowered by the electro-hydraulic push rod 32. In practical applications, the feeding direction and the running direction of the chain 22 can be selected as needed.

[0030] In one specific embodiment of this utility model, a vertical guide rail 13 is also provided on the outer wall of the machine body 1. The guide rail 13 is arranged at the feed inlet 12, and the lifting baffle 31 is limited and fitted on the guide rail 13.

[0031] In one specific embodiment of the present invention, each link 221 of the chain 22 is provided with a scraper 223.

[0032] In one specific embodiment of this utility model, the sprocket 21 at the top of the body 1 is the driving wheel, and the sprocket 21 at the bottom of the body 1 is the driven wheel. A tensioning device 4 is provided at the driven wheel.

[0033] In one specific embodiment of the present invention, a mating groove 2112 for receiving the body of a link 221 is formed on the chain tooth 211, and the mating groove 2112 is arranged on the outer peripheral surface of the chain tooth 211.

[0034] Another aspect of this utility model provides a ship unloader, including the aforementioned bidirectional vertical buried scraper elevator.
