DETAILED DESCRIPTION

[0034] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.

[0036] like Figures 1 to 6 As shown, the embodiment of the present application provides a deep-sea polymetallic nodule rotary rake collection device, including a collection vehicle 1;

[0037] The ore rake mechanism includes a support arm 3 and a rotating rake installed on the support arm 3. There are two ore rake mechanisms, which are arranged in a V shape in front of the ore collecting vehicle 1. The rotating rake includes a fixed portion 5, a rotating portion 6 and a tooth rake 7. The fixed portion 5 is connected to the support arm 3, the rotating portion 6 is rotatably connected to the fixed portion 5, and the tooth rake 7 is fixed on the rotating portion 6;

[0038] A driving mechanism, the driving mechanism is connected between the ore collecting vehicle 1 and the support arm 3, and drives the support arm 3 to rotate relative to the ore collecting vehicle 1;

[0039] A suction pipe 4, one end of which is fixed on the tooth rake 7, and the other end of which extends to the ore collecting vehicle 1; the suction pipe 4 is used to suck away the plume;

[0040] The rolling collection mechanism 2 is tilted, and one end of the rolling collection mechanism 2 is connected to the collection port on the ore collecting vehicle 1, and the other end extends between the two ore rake mechanisms.

[0041] Specifically, in some embodiments of the present application, the ore collecting vehicle 1 is a crawler ore collecting vehicle 1, which has an ore collecting bin and a collecting port connected to the ore collecting bin, the collecting port is located at the front of the crawler ore collecting vehicle 1, and the rolling collecting mechanism 2 is a chain conveyor belt, one end of the chain conveyor belt is arranged at the collecting port, and the other end extends between two ore scraping mechanisms, which is used to transfer the ore strips collected by the ore scraping mechanisms to the ore collecting bin for collection.

[0042] The raking mechanism forms horizontal rotation through the rotation of the rotating part 6 and the tooth rake 7, reduces the raised sediment and avoids the formation of excessive plume flow, and through the rotation of multiple rotating rakes, the ore strips can be collected between the two raking mechanisms, and the two raking mechanisms are arranged in a V shape, and along the direction away from the ore collecting vehicle 1 (from back to front), the distance between the two raking mechanisms gradually increases, so that the tooth rakes 7 of the two raking mechanisms collect the ore strips to the position between the two raking mechanisms near the ore collecting port, thereby facilitating the collection of the rolling collection mechanism 2. The fixed part 5 of the rotating rake is connected to the support arm 3 through a hydraulic rod, and the height of each rotating rake is adjusted in real time by the extension and contraction of the hydraulic rod to adapt to the changes in the terrain and ensure the stability of the rotating rake.

[0043] Furthermore, in some embodiments of the present application, the support arm 3 is rotatably connected to the ore collecting vehicle 1, and a driving mechanism is provided between the support arm 3 and the ore collecting vehicle 1, and the driving mechanism drives the ore collecting vehicle 1 to rotate relative to the ore collecting vehicle 1 to adjust the angle between the two support arms 3. In the specific use process, the angle between the two support arms 3 can be adjusted according to the actual situation to adapt to different working environments.

[0044] Furthermore, in some embodiments of the present application, the support arm 3 includes multiple sections of connecting arms 301 that are hinged in sequence, and the multiple sections of connecting arms 301 can be folded. When working, the support arm 3 is opened, and the rotating rake rotates to collect polymetallic nodules, thereby expanding the operating range of the ore collecting vehicle 1, realizing large-scale collection of polymetallic nodules, and improving production capacity. When work is not required, the support arm 3 can be folded to reduce the size of the single unit and avoid damage during driving in the case of non-collection operations such as deployment and recovery.

[0045] Furthermore, in some embodiments of the present application, at least one rotating rake is provided on each connecting arm 301 to ensure that each connecting arm 301 can perform collection operations. By configuring the support arm 3 as a multi-section hinged connecting arm 301, not only can the tooth rake 7 be recovered, the extension length of the tooth rake 7 can be reduced, and walking in a non-operating state can be facilitated, but also the working length of the support arm 3 can be adjusted as needed. When the support arm 3 is fully opened, the horizontal extension length of the support arm 3 reaches the maximum, expanding the working width of a single collection device.

[0046] Further, in some embodiments of the present application, the fixed part 5 includes a fixed disk, which is in the shape of a disk, and a mounting groove is provided on the outer circumferential surface of the fixed disk along the circumferential direction, the rotating part 6 includes a rotating disk, which is in the shape of an annular disk, and the rotating disk is rotatably installed in the mounting groove, and the number of tooth rakes is multiple, and multiple tooth rakes 7 are arranged at intervals along the axial direction of the rotating disk. During the rotation process, the rotating disk drives the tooth rakes to rotate synchronously horizontally, thereby collecting nodules and reducing the disturbance of bottom sediments.

[0047] Furthermore, in some embodiments of the present application, a first motor 11 is provided on the fixed disk, and the first motor 11 is meshedly connected to the rotating disk through gears to drive the rotating disk to rotate.

[0048] Specifically, the first motor 11 is fixed on the fixed disk, and the output shaft of the first motor 11 is provided with a first gear 12, and the rotating disk is provided with a second gear, the second gear is meshed with the first gear, and the second gear is an annular rack 13. When the output shaft of the first motor 11 rotates, the rotating disk is driven to rotate synchronously through the meshing structure of the first gear 12 and the second gear.

[0049] The number of the first motors 11 can be multiple, and the multiple first motors 11 are arranged at intervals along the circumference of the rotating disk, and the multiple first motors 11 rotate synchronously.

[0050] Furthermore, in some embodiments of the present application, a rotor 14 is provided between the rotating disk and the fixed disk, and the rotor 14 is disposed on the upper surface or the lower surface of the rotating disk.

[0051] Exemplarily, in some embodiments of the present application, the first motor 11 is located above the rotating disk, the rotor 14 is located between the lower surface of the rotating disk and the lower side wall of the mounting groove, the number of the rotors 14 is multiple, and the multiple rotors 14 are arranged at intervals along the radial and circumferential directions of the rotating disk to enable the rotating disk to rotate smoothly. The rotor 14 can be set as a ball to reduce the friction between the rotating disk and the lower side wall of the mounting groove.

[0052] The rotation speed of the first motor 11 determines the rotation speed of the rotating disk and the tooth rake. Therefore, the rotation speed of the first motor 11 can be determined according to the conditions such as the driving speed of the ore collecting vehicle 1, the particle size of the nodule ore, the sediment disturbance characteristics, etc. The rotation speed of the rotating disk and the tooth rake can be adjusted by adjusting the rotation speed of the first motor 11 to make the nodule ore as evenly and continuously distributed in the middle zone of the two rake mechanisms as possible, thereby creating conditions for subsequent ore transportation.

[0053] Furthermore, in some embodiments of the present application, the tooth rake includes a fixed sleeve 73, a rotating sleeve 74, a fixed tooth rake rod 71 and a rotating tooth rake rod 72, the fixed sleeve 73 is fixed on the rotating disk along the radial direction of the rotating disk, the rotating sleeve 74 is rotatably arranged in the fixed sleeve 73, and the rotating sleeve 74 is coaxially arranged with the fixed sleeve 73; specifically, the outer diameter of the rotating sleeve 74 is smaller than the inner diameter of the fixed sleeve 73, and can rotate freely in the fixed sleeve 73.

[0054] The fixed sleeve 73 is provided with a fixed tooth rake rod 71 and an arc groove 731. The fixed tooth rake rod 71 is arranged below the fixed sleeve 73 in a direction perpendicular to the fixed sleeve 73, and the number of the fixed tooth rake rods 71 ​​is multiple, and the multiple fixed tooth rake rods 71 ​​are arranged at intervals along the axial direction of the fixed sleeve 73; the arc grooves 731 are arranged along the circumference of the fixed sleeve 73, and the number of the arc grooves 731 is multiple, and the multiple arc grooves 731 are arranged at intervals along the axial direction of the fixed sleeve 73, and the multiple arc grooves 731 are arranged alternately with the multiple fixed tooth rake rods 71. Specifically, the distance between any two fixed tooth rake rods 71 ​​is equal, and an arc groove 731 is arranged between any two fixed tooth rake rods 71. The spacing between two adjacent fixed tooth rake rods 71 ​​and the length of the fixed tooth rake rods 71 ​​are determined according to the particle size range and burial depth of the nodule ore in the mining area, so as to ensure that the collection rate is not less than 90%.

[0055] The rotating sleeve 74 is provided with a rotatable tooth rake rod 72 at a position corresponding to the arc groove 731, one end of the rotatable tooth rake rod 72 is connected to the rotating sleeve 74, and the other end passes through the fixed sleeve 73 from the arc groove 731. When the rotating sleeve 74 rotates, the rotatable tooth rake rod 72 can rotate in the arc groove 731, and the rotatable tooth rake rod 72 reciprocates between the locked state and the unlocked state. When the rotatable tooth rake rod 72 is in the locked state, the rotatable tooth rake rod 72 and the fixed tooth rake rod 71 are located on a straight line parallel to the axial direction of the fixed sleeve 73, and the rotatable tooth rake rod 72 and the fixed tooth rake rod 71 play the same role, and can push the semi-buried plate-shaped tuberculosis ore to the middle position of the two rake mechanisms to gather into ore strips. In the unlocked state, the rotatable tooth rake rod 72 can rotate along the arc groove, change the spacing between the rotatable tooth rake rod 72 and the fixed tooth rake rod 71, and release the tuberculosis ore stuck between the two.

[0056] By setting the rotatable tooth rake rod 72, the number and spacing of the working tooth rake rods can be adjusted. The number and spacing of the tooth rake rods involved in the work can be adjusted according to the particle size of the nodules in the mining area to prevent the nodule ore from being stuck. When the nodule ore in the mining area is stuck, the rotatable tooth rake rod 72 is controlled to rotate upward, thereby causing the rotatable tooth rake rod 72 to deviate from the working position, increasing the distance between the end of the rotatable tooth rake rod 72 and the end of the adjacent fixed tooth rake rod 71, and the stuck combined ore is released.

[0057] Furthermore, in some embodiments of the present application, a cavity 61 is provided inside the rotating disk, and a second motor 18 is installed in the cavity 61 . The second motor 18 is connected to the rotating sleeve 74 to drive the rotating sleeve 74 to rotate.

[0058] Specifically, the second motor 18 is fixed in the cavity 61 through the mounting bracket 62, and the output shaft of the second motor 18 passes through the cavity 61 and is fixedly connected to the rotating sleeve 74, so as to drive the rotating sleeve 74 to rotate. The rotating sleeve 74 is driven to rotate by the second motor 18, so as to control the rotation angle and position of the rotating sleeve 74, and the rotation of the rotating sleeve 74 is controlled by controlling the forward and reverse rotation of the second motor 18.

[0059] Furthermore, the rotatable tooth rake rod includes a sleeve housing 721, a third motor 75 and two replaceable tooth rake rods 722, the sleeve housing 721 is fixedly connected to the rotating sleeve 74 along an axial direction perpendicular to the rotating sleeve 74, one replaceable tooth rake rod 722 is located inside the sleeve housing 721, one end of the other replaceable tooth rake rod 722 is located inside the sleeve housing 721, and the other end extends out of the sleeve housing 721, wherein the replaceable tooth rake rod 722 extending out of the sleeve housing 721 is a working tooth rake rod. The rake rod, the replaceable tooth rake rod 722 located inside the sleeve shell 721 is a spare tooth rake rod, and the upper end of the spare tooth rake rod is connected to the push rod of the third motor 75. The push rod of the third motor 75 is arranged along the axial direction of the sleeve shell 721 and can make a linear motion along the axial direction of the sleeve shell 721. When the push rod of the third motor 75 is extended, the spare tooth rake rod can be pushed downward, and then the working tooth rake rod is pushed out, and the spare tooth rake rod moves to the position of the original working tooth rake rod to act as a new working tooth rake rod.

[0060] Specifically, the interior of the sleeve housing 721 is divided into a spare chamber 7211 and a clamping chamber 7222 located at the top by a partition, wherein a connecting port is provided on the partition, and the diameter of the connecting port is larger than the diameter of the replaceable tooth rake rod 722, and smaller than the inner diameter of the spare chamber 7211. The spare tooth rake rod is located in the spare chamber 7211, and the upper end of the working tooth rake rod is clamped in the clamping chamber 7222. The spare tooth rake rod has the same structure as the working tooth rake rod. Taking the working tooth rake rod as an example, a fixing groove is provided on the side wall of the upper end of the working tooth rake rod, and a clamping block 723 is provided in the fixing groove. One end of the clamping block 723 is connected to the fixing groove by a spring 724, and the other end extends out of the fixing groove. When subjected to external force, the clamping block 723 can be retracted into the fixing groove along the radial direction of the working tooth rake rod. When the external force disappears, the clamping block 723 extends outward under the action of the spring 724 to achieve reset. When the block 723 is not acted upon by external force, the end of the block 723 protrudes from the outer circumferential surface of the working tooth rake rod under the action of the spring 724, and the partition acts as a barrier to the block 723 to prevent the working tooth rake rod from moving upward when receiving external force.

[0061] The side surface of the clamping block 723 facing the lower end of the working tooth rake rod is an inclined surface, and the inner diameter of the lower part of the clamping cavity 7222 gradually decreases from top to bottom. In other words, the inner wall of the lower part of the clamping cavity 7222 is an inclined surface, and the inclined surface of the lower part of the clamping cavity 7222 has the same inclination angle as the inclined surface on the clamping block 723. When the working tooth rake rod is subjected to a downward force, the inner wall of the clamping cavity 7222 squeezes the clamping block 723, so that the clamping block 723 moves in the direction of retracting the installation groove, thereby enabling the clamping block 72 The clamping cavity 7222 is disengaged from the lower end of the clamping cavity 7222, thereby realizing the disassembly of the working tooth rake rod; at the same time, under the thrust of the push rod of the third motor 75, the spare tooth rake rod moves downward until the clamping block 723 on the spare tooth rake rod passes through the connecting port on the partition plate and enters the clamping cavity 7222, and the clamping block 723 on the spare tooth rake rod is clamped and fixed with the clamping cavity 7222, replacing the original working tooth rake rod, and automatically restoring the normal working state of the rotatable tooth rake, thereby reducing the failure rate.

[0062] In addition, by adjusting the length of the third motor 75, the length of the spare tooth rake rod extending out of the sleeve housing 721 can also be adjusted, thereby adjusting the working length of the spare tooth rake rod, which is suitable for disturbing nodule ores in mining areas of different depths.

[0063] Furthermore, in some embodiments of the present application, the rotary rake also includes a sled plate 15, a first electric push rod 17 and a second electric push rod 16, the upper end of the first electric push rod 17 is fixedly connected to the fixed disk via a fixed connection portion 172, the lower end of the first electric push rod 17 is rotatably connected to the sled plate 15, and both ends of the second electric push rod 16 are rotatably connected to the fixed disk and the sled plate 15 respectively, and a sled blade 151 is provided on the lower surface of the sled plate 15.

[0064] Specifically, the first electric push rod 17 is located behind the second electric push rod 16. The front and rear mentioned here are related to the traveling direction of the ore collecting vehicle 1. The ore collecting vehicle 1 travels from the back to the front, and the front end of the sled 15 tilts upward. The lower end of the first electric push rod 17 is rotatably connected to the rear end of the sled 15 through the first connector 171, the upper end of the second electric push rod 16 is rotatably connected to the fixed plate through the second connector 161, and the lower end of the second electric push rod 16 is rotatably connected to the front end of the sled through the third connector 162. The first motor push rod 17 and the second motor push rod 16 can adjust the height and front and rear tilt angle of the sled 15 to ensure that the sled 15 touches the bottom with a certain ground contact pressure ratio. The height and tilt angle of the sled 15 change with the change of the seabed terrain, ensuring the stability of the height above the ground. The sled blade 151 is set on the lower surface of the sled 15 to improve the stability of the sled 15 and prevent the rotary rake from tilting during the forward movement and rotation.

[0065] Furthermore, in some embodiments of the present application, a suction channel 10 is axially opened at the center of the fixed disk, and the suction channel 10 passes through the upper and lower surfaces of the fixed disk. The suction pipe 4 includes a main pipe and a branch pipe. The number of the branch pipes is equal to the number of rotating rakes and is arranged one by one. The branch pipe is connected and fixed to the upper end of the suction channel 10 through a flange structure 9, and the feather flow at the center of the rotating rake is sucked away, which can reduce the range of bottom sediment disturbance and avoid the impact pit caused by hydraulic jets.

[0066] Furthermore, in some embodiments of the present application, the rotary rake further includes a baffle 8, which is disposed in front of the moving direction of the tooth rake and connected to the fixed disk.

[0067] Specifically, the baffle 8 is arc-shaped and is located between the ends of two adjacent tooth rakes to prevent the nodule ore from moving to the outside of the rotating disk. By controlling the rotation direction of the rotating rake and using it in combination with the baffle 8, it is ensured that the nodule ore moves between the two rake mechanisms, further improving work efficiency.

[0068] Furthermore, in some embodiments of the present application, the fixed tooth rake rod 71 and the replaceable tooth rake rod 722 are made of a material with a certain rigidity, which can bend when encountering a hard area and penetrate when encountering a soft area, thereby reducing the risk of broken teeth. At the same time, a wear-resistant rubber layer is wrapped around the outside of the fixed tooth rake rod 71 and the replaceable tooth rake rod 722 to prevent the nodule ore from being broken.

[0069] Furthermore, in some embodiments of the present application, a plume diffusion prevention cover is installed above the rotary rake, and a sewage suction machine is arranged inside to quickly filter dirt from the disturbed bottom sediment and reduce the height of the plume.

[0070] Furthermore, nozzles are installed on both sides of the chain conveyor belt to wash the surface of the nodule ore on the chain conveyor belt, and the amount of sediment entering the ore collecting bin is reduced through the vibration screening device.
