[0021] Beneficial effects: The present invention adds the above-mentioned chute guiding device to the ship unloader and uses it in conjunction with a liftable beam support assembly, so that the chute guiding device can adjust the opening position of the feed port assembly as the height of the beam support assembly changes, and at the same time close other positions of the feed port assembly, thereby reducing dust during material transportation, reducing pollution to the environment, and achieving the purpose of environmental protection.

[0022] In an optional embodiment, the beam support assembly includes a first beam and a second beam arranged on both sides of the sleeve support; the first beam is provided with a driving mechanism, and the second beam is provided with the first conveying mechanism and the chute material guiding device.

[0023] Beneficial effects: The present invention drives the sleeve bracket to slide up and down on the tower bracket through the driving mechanism arranged on the first crossbeam, so that the discharge end of the first conveying mechanism can move up and down along the height direction of the tower bracket, thereby changing the position of the discharge end of the first conveying mechanism on the chute guiding device to realize the guiding function of the chute guiding device at different heights.

[0024] In an optional embodiment, a pair of oppositely arranged first pulleys are provided on the end surface of the sleeve bracket facing the first crossbeam; a pair of oppositely arranged second pulleys are provided on the end surface of the sleeve bracket facing the second crossbeam; a pair of oppositely arranged third pulleys are provided on the side of the upper end surface of the tower bracket close to the first pulley, and a pair of oppositely arranged fourth pulleys are provided on the side close to the second pulley; the driving mechanism is connected to one of the first pulleys, one of the third pulleys, one of the fourth pulleys and one of the second pulleys in sequence through a steel wire rope, and then connected to another second pulley, another fourth pulley, another third pulley and another first pulley, and finally connected back to the driving mechanism.

[0025] Beneficial effects: The present invention connects the pulleys on the tower support and the sleeve support through a steel wire rope, which can effectively transmit the power of the driving mechanism to each pulley, thereby driving the sleeve support to move back and forth on the tower support.

[0040] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0041] Aiming at the problem that the existing chute device has poor sealing performance during the up and down movement of the beam of the ship unloader, the present invention provides a chute material guiding device and a ship unloader.

[0042] The following combination Figures 1 to 3 , describing embodiments of the present invention.

[0043] According to an embodiment of the present invention, on the one hand, Figure 1 As shown, a chute material guiding device is provided, comprising: a chute body 1, a feed port assembly 2 and a feed conduit 3.

[0044] Specifically, a material guide channel 101 is provided inside the chute body 1; the feed port assembly 2 is arranged on the side wall of the chute body 1 and is connected to the material guide channel 101, including a first end face 201 and a second end face 202 arranged opposite to each other along the height direction of the chute body 1, and a plurality of elastic baffle assemblies overlapping in sequence are provided between the first end face 201 and the second end face 202; the plurality of elastic baffle assemblies can close the feed port assembly 2, and the elastic baffle assembly includes a pair of elastic baffles arranged opposite to each other on the first end face 201 and the second end face 202 and overlapping each other; the feed conduit 3 is movably arranged between the pair of elastic baffles, and the feed port assembly 2 is opened so that the feed conduit 3 is connected to the material guide channel 101.

[0045] The embodiment of the present invention utilizes the retractable characteristics of the elastic baffle assembly to adjust the relative position of the feed conduit 3 between the first end face 201 and the second end face 202 according to the requirements under different working conditions, thereby realizing partial opening and closing of the feed port assembly 2.

[0046] It is understandable that when it is necessary to connect a certain position of the feed port assembly 2 with the material guide channel 101, it is only necessary to move the feed conduit 3 to that position, and the elastic baffles that are in contact with the feed conduit 3 and located on both sides of the feed conduit 3 will move toward the first end face 201 or the second end face 202 connected thereto, respectively. Furthermore, the force between the feed conduit 3 and the elastic baffles can also fix the feed conduit 3, which helps to avoid shaking or misalignment of the feed conduit 3 during the material conveying process, thereby ensuring smooth transportation of the material. When it is necessary to disconnect the connection between a certain position of the feed port assembly 2 and the material guide channel 101, it is only necessary to move the feed conduit 3 away from that position. By utilizing the shrinkable characteristics of the elastic baffle assembly, the compressed elastic baffle will gradually return to its original state, thereby reclosing the connection channel between the feed port assembly 2 and the material guide channel 101.

[0047] It should be noted that in this embodiment, the upper end of the chute body 1 is also equipped with an end cap for sealing the material guide channel 101 to reduce dust during material transportation. The lower end of the chute body 1 is provided with an opening connected to the material guide channel 101. This opening guides the material in the material guide channel 101 and is connected to the subsequent conveying mechanism.

[0048] According to one embodiment of the present invention, the lower surface of the upper elastic baffle assembly is sequentially overlapped with the upper surface of the lower elastic baffle assembly. In this embodiment, by sequentially overlapping the lower surface of the upper elastic baffle assembly with the upper surface of the lower elastic baffle assembly, the feed conduit 3 is facilitated to move up and down between the first end face 201 and the second end face 202, thereby smoothly squeezing the elastic baffles on both sides of the feed conduit 3, opening the feed port assembly 2, and connecting the feed conduit 3 with the material guide channel 101.

[0049] It is understandable that the upper surface of the elastic baffle assembly located above can also be overlapped with the lower surface of the elastic baffle assembly located below in turn.

[0050] According to one embodiment of the present invention, Figure 1As shown, the elastic baffle includes an elastic member 203 and a curved plate 204. One end of the elastic member 203 is disposed on the first end surface 201 or the second end surface 202, and the other end is connected to the curved plate 204. The end of the curved plate 204 facing away from the elastic member 203 is a curved end surface, that is, the curved end surface of the curved plate 204 contacts the outer wall of the feed conduit 3. In this embodiment, the elastic baffle, by using the curved plate 204, can facilitate smoother movement of the feed conduit 3 between the first end surface 201 and the second end surface 202, preventing the feed conduit 3 from becoming stuck and unable to compress the elastic baffle. It should be noted that in this embodiment, the elastic member 203 may be a spring.

[0051] According to an embodiment of the present invention, on the other hand, Figure 2 and Figure 3 As shown, a ship unloader is also provided, comprising: a tower support 4, a sleeve support 5, a beam support assembly 6, a driving mechanism 7, a material taking mechanism 8 and a first conveying mechanism 9.

[0052] Specifically, the tower bracket 4 is installed on the ground; the sleeve bracket 5 is sleeved on the tower bracket 4 and is slidably connected to the tower bracket 4; the beam bracket assembly 6 is arranged on the sleeve bracket 5 and extends in a direction away from the sleeve bracket 5; the driving mechanism 7 is arranged on the beam bracket assembly 6, and is arranged to drive the sleeve bracket 5 to slide on the tower bracket 4; the feeding mechanism 8 includes a feeding port and a discharging port, the feeding port of the feeding mechanism 8 digs materials from the cabin, and the discharging port of the feeding mechanism 8 is arranged on the beam bracket assembly 6; the first conveying mechanism 9 is arranged on the beam bracket assembly 6, including a feeding end and a discharging end, the feeding end of the first conveying mechanism 9 is connected to the discharging port of the feeding mechanism 8, and the discharging end of the first conveying mechanism 9 is connected to the feeding conduit 3 in the above-mentioned chute guiding device.

[0053] This embodiment adds the above-mentioned chute guiding device to the ship unloader and uses it in conjunction with the liftable beam support assembly 6, so that the chute guiding device can adjust the opening position of the feed port assembly 2 according to the height change of the position of the beam support assembly 6, and at the same time realize the closure of other positions of the feed port assembly 2, thereby reducing dust during material transportation, reducing pollution to the environment, and achieving the purpose of environmental protection.

[0054] In one example, the tower support 4's columns are equipped with sliding tracks extending along the tower support 4's height, and the sleeve support 5 is equipped with rollers adapted to slide on the sliding tracks. In this embodiment, the tower support 4 is shaped like a rectangular parallelepiped, with the aforementioned sliding tracks provided on each of the tower support 4's columns, which are arranged opposite each other. The sleeve support 5 is also shaped like a rectangular parallelepiped, with through-holes formed within the sleeve support 5 for the tower support 4 to pass through, and rollers adapted to slide on the sliding tracks are provided within the sleeve support 5. It is understood that the height of the sleeve support 5 needs to be less than that of the tower support 4.

[0055] In addition, the ship unloader of the embodiment of the present invention also has all the advantages of the above-mentioned chute material guiding device, which will not be described in detail here.

[0056] According to one embodiment of the present invention, Figure 2 Shown and Figure 3 As shown, the crossbeam support assembly 6 includes a first crossbeam 601 and a second crossbeam 602, which are arranged on opposite sides of the sleeve support 5. A drive mechanism 7 is provided on the end of the first crossbeam 601 away from the sleeve support 5, and a first conveying mechanism 9 is provided on the second crossbeam 602. The chute guide device is arranged on the second crossbeam 602 through the discharge end of the first conveying mechanism 9, with a gap between the second crossbeam 602 and the second crossbeam 602 to prevent the second crossbeam 602 from colliding with the chute guide device during the movement of the sleeve support 5, thereby affecting the normal operation of the ship unloader. It can be understood that in this embodiment, the drive mechanism 7 provided on the first crossbeam 601 drives the sleeve support 5 to slide up and down on the tower support 4, thereby enabling the discharge end of the first conveying mechanism 9 to move up and down along the height direction of the tower support 4, thereby changing the position of the discharge end of the first conveying mechanism 9 on the chute guide device, thereby realizing the material guiding function of the chute guide device at different heights.

[0057] According to one embodiment of the present invention, Figure 2 As shown, a pair of first pulleys 501 are provided on the end surface of the sleeve support 5 facing the first crossbeam 601; a pair of second pulleys 502 are provided on the end surface of the sleeve support 5 facing the second crossbeam 602; a pair of third pulleys 401 are provided on the upper end surface of the tower support 4 on the side near the first pulley 501, and a pair of fourth pulleys 402 are provided on the side near the second pulley 502; the driving mechanism 7 is connected to one of the first pulleys 501, one of the third pulleys 401, one of the fourth pulleys 402, and one of the second pulleys 502 in sequence through a steel wire rope, and then connected to another second pulley 502, another fourth pulley 402, another third pulley 401, and another first pulley 501, and finally connected back to the driving mechanism 7. In this embodiment, the pulleys on the tower support 4 and the sleeve support 5 are connected by steel wire ropes, which can effectively transmit the power of the driving mechanism 7 to each pulley, thereby driving the sleeve support 5 to move back and forth on the tower support 4.

[0058] It should be noted that the driving mechanism 7 can be one or two drums. Taking the wire rope connection relationship of the two drums as an example, the two drums are arranged at the end of the first beam 601 away from the sleeve support 5, and one of the drums is connected to one of the first pulleys 501, one of the third pulleys 401, one of the fourth pulleys 402 and one of the second pulleys 502 in sequence through the wire rope, and then connected to another second pulley 502, another fourth pulley 402, another third pulley 401 and another first pulley 501, and finally connected back to the other drum. It is understandable that when the two drums are winding up the wire rope at the same time, the sleeve support 5 will drive the beam support assembly to rise in the height direction of the tower support 4; when the two drums are releasing the wire rope at the same time, the sleeve support 5 will drive the beam support assembly to descend in the height direction of the tower support 4.

[0059] According to one embodiment of the present invention, Figure 3 As shown, the first conveying mechanism 9 includes a scraper 901 and a belt conveyor 902. One end of the scraper 901 is located below the discharge port of the reclaiming mechanism 8, and the other end of the scraper 901 is located above the belt conveyor 902. The conveying direction of the scraper 901 is arranged perpendicular to the extension direction of the belt conveyor 902. In this embodiment, the provision of the scraper effectively connects the discharge port of the reclaiming mechanism and the belt conveyor, ensuring continuous material transportation.

[0060] According to one embodiment of the present invention, Figure 2 As shown, the ship unloader further includes a material buffer pool 10. One end of the material buffer pool 10 is connected to a material guide channel 101 of the chute body 1, which is arranged along the height of the tower support 4. The other end of the material buffer pool 10 is inclined toward the ground. As can be understood, in this embodiment, because the chute body 1 is arranged along the height of the tower support 4, the material within the chute body 1 has a relatively high falling velocity. Therefore, the inclined material buffer pool 10 can slow the velocity of the material within the material guide channel 101, reducing the impact of the material on subsequent equipment and improving the continuity of material transportation.

[0061] According to one embodiment of the present invention, Figure 2As shown, a second conveying mechanism 11 is provided at one end of the material buffer tank 10 away from the chute body 1. In this embodiment, the second conveying mechanism 11 includes a corrugated sidewall belt conveyor 1101, a hopper head 1102, and a terminal belt conveyor 1103. The corrugated sidewall belt conveyor 1101 is connected to the chute body 1 at one end and to the hopper head 1102 at the other end. The material guide port of the hopper head 1102 is connected to the terminal belt conveyor 1103. It should be noted that the corrugated sidewall belt conveyor 1101 differs from a conventional conveyor belt in that the conveyor belt direction of the corrugated sidewall belt conveyor 1101 can be adjusted based on the position of the hopper head 1102 and the terminal belt conveyor, thereby transporting material from the material buffer tank 10 to a designated location at the terminal, ensuring continuous material transportation and preventing material accumulation. Furthermore, the hopper head 1102 can be provided with multiple guide ports to accommodate more terminal belt conveyors 1103, thereby improving material transportation efficiency.

[0062] According to one embodiment of the present invention, Figure 2 As shown, the ship unloader further includes a reclaiming mechanism trolley 12 and a slewing mechanism mounted on the reclaiming mechanism trolley 12. The reclaiming mechanism trolley 12 is mounted on the crossbeam support assembly 6 and is adapted to move along the length of the crossbeam support assembly 6. The slewing mechanism is sleeved around the circumference of the reclaiming mechanism 8 and adapted to drive the reclaiming mechanism 8 to rotate. In this embodiment, the reclaiming mechanism 8 is mounted on the crossbeam support assembly 6 via the reclaiming mechanism trolley 12, allowing the reclaiming mechanism 8 to move along with the reclaiming mechanism trolley 12 in the direction of the extension of the crossbeam support assembly 6, thereby increasing the working range of the reclaiming mechanism 8 to adapt to the requirements of different working conditions. In addition, by providing the slewing mechanism on the reclaiming mechanism 8, the reclaiming mechanism 8 can be rotated horizontally relative to the reclaiming mechanism trolley, so that the reclaiming opening of the reclaiming mechanism 8 can always face the material to be reclaimed, thereby improving the filling rate of the reclaiming opening of the reclaiming mechanism 8 during the reclaiming process and the overall operating efficiency of the chain bucket ship unloader.

[0063] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention. Such modifications and variations are all within the scope defined by the appended claims.
