[0031] In the material taking system described in any of the above schemes, the material taking device is arranged on the main beam and is suitable for moving along the main beam.

[0032] The technical solution of the present invention has the following advantages:

[0033] 1. The present invention provides a material picking system, comprising: a material picking device, suitable for digging materials; a pushing and scraping tank cleaning device, which is arranged on the side of the material picking device along the movement direction of the material picking device, and the pushing and scraping tank cleaning device comprises: a rod body assembly, one end of which is rotatably connected to the side of the material picking device, and the other end is extended in a direction away from the material picking device; a pushing and scraping member is arranged on a side where the rod body assembly is extended, and the pushing and scraping member at least partially extends downward; a pushing and scraping lifting structure is arranged between the material picking device and the pushing and scraping tank cleaning device, and the fixed end of the pushing and scraping lifting structure is connected to the material picking device, and the movable end of the pushing and scraping lifting structure is rotatably connected to a side of the pushing and scraping tank cleaning device away from the material picking device, and the movable end of the pushing and scraping lifting structure is suitable for performing telescopic movement relative to the fixed end of the pushing and scraping lifting structure, thereby driving the pushing and scraping tank cleaning device to a first expanded state away from the material picking device, or a first retracted state retracted toward the material picking device.

[0034] The present invention provides a material taking system, wherein a rod assembly is used as an extension part to extend into some corner positions below the hatch coaming of a cargo ship, and a part of a push and scraper member extending downward is used to scrape out materials at some corner positions during the synchronous movement of the push and scraper tank cleaning device as a whole with the material taking device, and a push and scraper lifting structure is used to drive the push and scraper tank cleaning device to rotate to a suitable height position, so that during the synchronous movement of the push and scraper tank cleaning device as a whole with the material taking device, materials at different positions are scraped out to ensure the integrity of the unloaded materials. Thus, the defect that the material taking device in the prior art cannot extend into some corner positions below the hatch coaming of a cargo ship to unload materials, so that the materials cannot be completely cleaned.

[0035] 2. The present invention provides a material picking system, wherein the rod body assembly includes a plurality of parallel extending rods, one end of each extending rod is hinged to the side of the material picking device, and the other end of each extending rod is hinged to the pushing and scraping member.

[0036] Taking the case where there are two extension rods as an example, at this time, the partial structure between the two hinged positions on the side of the material-grabbing device, the two extension rods and the push-pull member together form a four-bar linkage. Under the transmission action of the four-bar linkage, when the four-bar linkage is in different forms, the push-pull member always maintains a posture parallel to the line connecting the two hinged positions on the side of the material-grabbing device at different positions, that is, the push-pull member is always extended downward, thereby improving the efficiency of material grabbing while adapting to different material stacking environments in some corners under the hatch coaming of the cargo ship.

[0037] 3. The present invention provides a material taking system, wherein the pushing and scraping members are multiple and are arranged in parallel along the extending direction of the extending rod.

[0038] A plurality of pushing and scraping members are arranged, and during the synchronous movement with the material-retrieving device, the plurality of pushing and scraping members simultaneously scrape the material, thereby further improving the efficiency of scraping the material.

[0039] 4. The present invention provides a material taking system, wherein the pushing and clearing device is arranged on both sides of the material taking device along the moving direction of the material taking device.

[0040] Since the hatch coamings of a cargo ship are generally located on both sides of the cargo ship and are at both ends of the movement direction of the material-retrieving device, when the material-retrieving device moves close to one side coaming, the pushing and shoveling cleaning device close to that side falls to the first deployed state under the action of the pushing and shoveling lifting structure, and extends into some corner positions under the coaming during further movement of the material-retrieving device to complete subsequent material unloading operations. Correspondingly, when the material-retrieving device moves close to the other side coaming, the pushing and shoveling cleaning device close to that side is operated in the same way, thereby completely unloading the materials in some corner positions under the coamings on both sides.

[0041] 5. The present invention provides a material retrieving system, wherein the push-pull lifting structure comprises: a push-pull lifting reel, connected to the material retrieving device, and the push-pull lifting reel is power-connected to a push-pull reel driving motor; a push-pull connecting rope, one end of which is wound around the push-pull lifting reel, and the other end is connected to a side of the push-pull cleaning device away from the material retrieving device.

[0042] The push-pick lifting reel is fixedly connected to the material picking device as the fixed end of the push-pick lifting structure. Under the driving action of the push-pick lifting reel driving motor on the push-pick lifting reel, the push-pick lifting reel rotates to wind the push-pick connecting rope around the outer wall of the push-pick lifting reel or release the push-pick connecting rope, so that the push-pick connecting rope is shortened or lengthened, thereby switching the push-pick cleaning device connected to the push-pick connecting rope between the first unfolded state and the first retracted state.

[0043] 6. The present invention provides a material picking system, further comprising: a tank cleaning device, arranged on the other side of the material picking device, the tank cleaning device being arranged adjacent to the pushing and shoveling tank cleaning device, and the tank cleaning device being suitable for gathering materials in a direction close to the material picking device; a first lifting structure, arranged between the material picking device and the tank cleaning device along the length direction of the material picking device, the fixed end of the first lifting structure being connected to the material picking device, the movable end of the first lifting structure being connected to the tank cleaning device, and the movable end of the first lifting structure being suitable for telescopic movement relative to the fixed end of the first lifting structure.

[0044] By arranging a first lifting structure between the material taking device and the tank cleaning device, and utilizing the telescopic effect of the first lifting structure to adjust the relative positions of the tank cleaning device and the material taking device, the tank cleaning device is able to be away from the bottom material taking position of the material taking device when it is not needed to work, and the height difference between the bottom position of the tank cleaning device and the bottom material taking position of the material taking device is increased, thereby preventing the tank cleaning device from contacting part of the material on the side of the material taking device and scattering the material when the material taking device is operating normally, thereby ensuring that the material taking device can take material normally.

[0045] 7. The present invention provides a material picking system, wherein the movable end of the first lifting structure is rotatably connected to a side of the tank cleaning device close to the material picking device; the material picking system also includes a second lifting structure, which is arranged between the material picking device and / or the first lifting structure and the tank cleaning device, the fixed end of the second lifting structure is connected to the material picking device and / or the fixed end of the first lifting structure, the movable end of the second lifting structure is rotatably connected to a side of the tank cleaning device away from the material picking device, and the movable end of the second lifting structure is suitable for performing telescopic movement relative to the fixed end of the second lifting structure, thereby driving the tank cleaning device to a second expanded state away from the material picking device, or a second retracted state retracted toward the material picking device.

[0046] The movable end of the first lifting structure is rotatably connected to a side of the tank cleaning device close to the material taking device. When the second lifting structure produces a telescopic effect, the tank cleaning device and the material taking device are adjusted to rotate around the rotating connection. When the tank cleaning device is in the viewing angle of the figure, the tank cleaning device rotates upward to switch from the second deployed state to the second retracted state.

[0047] 8. The present invention provides a material taking system, wherein the tank cleaning device is arranged on two opposite sides of the material taking device; and / or two tank cleaning devices are arranged side by side on one side of the material taking device.

[0048] The reclaiming device is provided with four side walls along the length direction, and the cleaning device is arranged on two opposite side walls of the reclaiming device to realize the collection operation of materials on the corresponding two sides of the reclaiming device, thereby improving the efficiency of material cleaning. Two cleaning devices are arranged side by side on one side wall of the reclaiming device, and they work simultaneously to realize the collection operation of materials, thereby improving the efficiency of material cleaning.

[0049] 9. The present invention provides a material taking system, wherein the tank cleaning device comprises: a mounting frame, one end of which is rotatably connected to the movable end of the first lifting structure, and the other end of which is rotatably connected to the movable end of the second lifting structure; a spiral blade, which is rotatably connected to the mounting frame, and after the spiral blade is rotated, it is suitable for gathering materials in the direction close to the material taking device; a tank cleaning drive motor, which is dynamically connected to the spiral blade; a support assembly, which is connected to the mounting frame, and the bottom height position of the support assembly is not lower than the bottom height position of the spiral blade, and the support assembly comprises a support wheel, which is suitable for rolling along the movement direction of the material taking device, and the support wheel is arranged along the movement direction of the material taking device.

[0050] The spiral blade pushes the material under the driving action of the cleaning drive motor, and the material moves along the extension direction of the spiral line of the spiral blade. Under the reasonable steering setting of the cleaning drive motor, the material is collected close to the material taking device, thereby realizing the cleaning operation. After the cleaning device is lowered, the support component forms a supporting effect on the top of the material or the bottom of the cabin. When the terrain is undulating, the support component is always close to the lower surface, driving the cleaning device to follow the terrain, so that the cleaning device can adapt to different cabin bottom environments and is also convenient for moving with the main material taking device. At the same time, the bottom height position of the support component is slightly lower than the bottom height position of the spiral blade, which maximizes the cleaning efficiency of the spiral blade while avoiding interference and damage to the cabin bottom wall during operation. After the cleaning device is lowered, by setting the support wheel, the support wheel rolls on the top of the material or the bottom of the cabin, improving the smoothness of the movement of the cleaning device. At the same time, in view of the different settings of the material taking device and the cabin cleaning device on different side walls of the material taking device, the support wheels are set along the movement direction of the material taking device, so that the support wheels are suitable for rolling along the movement direction of the material taking device, thereby facilitating the synchronous movement of the cabin cleaning device and the material taking device.

[0065] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0066] Example 1

[0067] This embodiment provides a material taking system, such as Figure 1-Figure 6 In the prior art, during the operation of the chain bucket ship unloader, due to the large main structure of the chain bucket, the material can only be dug directly below the hatch, and it is impossible to reach into some corners under the hatch coaming of the cargo ship to unload the material, so that the material cannot be completely cleaned, resulting in an additional cleaning process after unloading the ship using the chain bucket ship unloader, which requires a large amount of cleaning and is time-consuming and labor-intensive.

[0068] To this end, the material taking system provided in this embodiment is as follows: Figure 1-Figure 6 It includes: a material taking device 100, a pushing and scraping cabin cleaning device 206, a pushing and scraping lifting structure 209, etc.

[0069] The material taking device 100 is suitable for taking materials.

[0070] The pushing and clearing device 206 is arranged on the side of the material taking device 100 along the moving direction of the material taking device 100 .

[0071] Specifically, Figure 1 , Figure 2 As shown, the pushing and scraping cleaning device 206 is arranged along the moving direction of the material taking device 100. When the material taking device 100 moves laterally and takes materials by using the chain bucket, the pushing and scraping cleaning device 206 moves synchronously with the material taking device 100 and extends into some corner positions under the hatch coaming of the cargo ship to unload materials, thereby cleaning the materials in the corner positions during the synchronous movement.

[0072] The pushing and scraping cabin cleaning device 206 comprises a rod assembly and a pushing and scraping member 207 .

[0073] One end of the rod assembly is rotatably connected to the side of the material taking device 100 , and the other end is extended in a direction away from the material taking device 100 .

[0074] The push and pull member 207 is disposed on one side of the rod assembly extending therefrom, and at least a portion of the push and pull member 207 is extended downward.

[0075] Specifically, Figure 1 , Figure 2 As shown, the rod assembly extends into some corners below the hatch coaming of the cargo ship as an extension portion, and the downward extending portion of the pushing and scraping member 207 is utilized to scrape out materials in some corners during the synchronous movement of the pushing and scraping cleaning device 206 as a whole along with the material taking device 100, thereby achieving the purpose of unloading materials.

[0076] The pushing and scraping lifting structure 209 is arranged between the material picking device 100 and the pushing and scraping tank cleaning device 206. The fixed end of the pushing and scraping lifting structure 209 is connected to the material picking device 100, and the movable end of the pushing and scraping lifting structure 209 is rotatably connected to the side of the pushing and scraping tank cleaning device 206 away from the material picking device 100. The movable end of the pushing and scraping lifting structure 209 is suitable for telescopic movement relative to the fixed end of the pushing and scraping lifting structure 209, thereby driving the pushing and scraping tank cleaning device 206 to a first expanded state away from the material picking device 100, or a first retracted state retracted toward the material picking device 100.

[0077] Specifically, Figure 1 , Figure 2As shown, since the materials under the hatch coaming of the cargo ship are located at different heights, the push-pull lifting structure 209 is used to drive the push-pull cleaning device 206 to rotate to a suitable height position, so that when the push-pull cleaning device 206 moves synchronously with the material taking device 100 as a whole, the materials at different positions are pulled out to ensure the integrity of the unloaded materials. This overcomes the defect in the prior art that the material taking device 100 cannot extend into some corners under the hatch coaming of the cargo ship to unload materials, so that the materials cannot be completely cleaned.

[0078] Furthermore, the telescopic effect of the pushing and scraping lifting structure 209 is utilized to adjust the relative positions of the pushing and scraping cleaning device 206 and the material picking device 100, so that the pushing and scraping cleaning device 206 is away from the bottom material picking position of the material picking device 100 when it is not needed to work, and the height difference between the bottom position of the pushing and scraping cleaning device 206 and the bottom material picking position of the material picking device 100 is increased, thereby preventing the pushing and scraping cleaning device 206 from contacting part of the material on the side of the material picking device 100 and pushing the material away when the material picking device 100 is operating normally, thereby ensuring that the material picking device 100 can pick up materials normally.

[0079] Furthermore, the present embodiment does not limit the specific structural form of the push-pull lifting structure 209, as long as it can achieve the telescopic effect. The specific structural form of the push-pull lifting structure 209 can be a telescopic cylinder, a reel cable, etc.

[0080] On the basis of the above implementation manner, as a further limited implementation manner, Figure 1 , Figure 2 As shown, the rod assembly includes a plurality of parallel extending rods 208 , one end of the extending rods 208 is hinged to the side of the material taking device 100 , and the other end of the extending rods 208 is hinged to the pushing and scraping member 207 .

[0081] Specifically, taking the case where there are two extension rods 208 as an example, at this time, the partial structure between the two hinged positions on the side of the material picking device 100, the two extension rods 208 and the push-pull member 207 together constitute a four-bar linkage. Under the transmission action of the four-bar linkage, when the four-bar linkage is in different forms, the push-pull member 207 always maintains a posture parallel to the line connecting the two hinged positions on the side of the material picking device 100 at different positions, that is, the push-pull member 207 is always extended downward, thereby improving the efficiency of material picking while adapting to different material stacking environments in some corners under the hatch coaming of the cargo ship.

[0082] Furthermore, when multiple extension rods 208 are arranged in parallel, since the rods themselves occupy a certain volume, the multiple extension rods 208 need to be staggered in space along the height direction so that all the extension rods 208 can complete the retracting operation in parallel with each other.

[0083] On the basis of the above implementation manner, as a further limited implementation manner, Figure 1 , Figure 2 As shown, there are multiple pushing and pulling members 207 , which are arranged in parallel along the extension direction of the extension rod 208 .

[0084] Specifically, a plurality of pushing and scraping members 207 are provided, and during the synchronous movement of the material-grabbing device 100 , the plurality of pushing and scraping members 207 scrape materials at the same time, thereby further improving the efficiency of scraping materials.

[0085] On the basis of the above implementation manner, as a further limited implementation manner, Figure 1 , Figure 2 As shown, the pushing and clearing devices 206 are arranged on both sides of the material taking device 100 along the moving direction of the material taking device 100 .

[0086] Specifically, since the hatch coamings of a cargo ship are generally located on both sides of the cargo ship and are at both ends of the movement direction of the material-removing device 100, when the material-removing device 100 moves close to one side of the coaming, the pushing and scraping cleaning device 206 close to that side falls to the first deployed state under the action of the pushing and scraping lifting structure 209, and extends into some corner positions under the coaming during further movement of the material-removing device 100 to complete subsequent material unloading operations. Correspondingly, when the material-removing device 100 moves close to the other side of the coaming, the pushing and scraping cleaning device 206 close to that side is operated in the same way, thereby completely unloading the materials in some corner positions under the coamings on both sides.

[0087] On the basis of the above implementation manner, as a further limited implementation manner, Figure 1 , Figure 2 As shown, the push-pull lifting structure 209 includes: a push-pull lifting reel 2091 and a push-pull connecting rope 2092.

[0088] The push-pull lifting reel 2091 is connected to the material taking device 100, and the push-pull lifting reel 2091 is connected to the push-pull reel driving motor;

[0089] One end of the push-pull connecting rope 2092 is wound around the push-pull lifting reel 2091 , and the other end is connected to a side of the push-pull cleaning device 206 away from the material taking device 100 .

[0090] Specifically, the push-pull lifting reel 2091, as the fixed end of the push-pull lifting structure 209, is fixedly connected to the material picking device 100. Under the driving action of the push-pull lifting reel driving motor on the push-pull lifting reel 2091, the push-pull lifting reel 2091 rotates to wind the push-pull connecting rope 2092 around the outer wall of the push-pull lifting reel 2091 or release the push-pull connecting rope 2092, so that the push-pull connecting rope 2092 is shortened or lengthened, thereby switching the push-pull cabin cleaning device 206 connected to the push-pull connecting rope 2092 between the first unfolded state and the first retracted state.

[0091] On the basis of the above implementation manner, as a further limited implementation manner, Figure 1-Figure 6 As shown, the material taking system also includes: a tank cleaning device 200, a first lifting structure 210, etc.

[0092] The tank cleaning device 200 is arranged at the other side of the material taking device 100 . The tank cleaning device 200 is arranged adjacent to the pushing and scraping tank cleaning device 206 . The tank cleaning device 200 is suitable for gathering materials in a direction close to the material taking device 100 .

[0093] Specifically, Figure 1 , Figure 3 As shown, four side walls are formed on the material picking device 100 along the length direction, and the pushing and scraping cleaning device 206 is arranged along the movement direction of the material picking device 100, that is, the pushing and scraping cleaning device 206 is arranged on the side wall corresponding to the movement direction of the material picking device 100, and the cleaning device 200 is arranged adjacent to the pushing and scraping cleaning device 206, that is, they are arranged on the other two side walls of the material picking device 100. The cleaning device 200 is arranged perpendicular to the movement direction of the material picking device 100. During the movement of the material picking device 100, the cleaning device 200 gathers the materials in the direction close to the material picking device 100.

[0094] Furthermore, when the cleaning device 200 is in the second deployed state, that is, Figure 3 As shown, at this time, the collecting device provided on the cleaning device 200 will collect the materials within the downward mapping range thereof, and gather the materials at a position close to the retrieving chain bucket at the bottom of the retrieving device 100, so as to facilitate the retrieving chain bucket to complete the retrieving operation.

[0095] Furthermore, this embodiment does not limit the specific structural form of the tank cleaning device 200, as long as it can complete the material gathering operation. As one embodiment, the tank cleaning device 200 is provided with a scraper driven by a sprocket chain, and the scraper moves on the material to collect the material close to the material taking device 100, thereby completing the material gathering operation; as another embodiment, the tank cleaning device 200 is provided with a spiral blade driven by an external force, and the spiral blade moves on the material to collect the material close to the material taking device 100, thereby completing the material gathering operation.

[0096] The first lifting structure 210 is arranged between the material picking device 100 and the tank cleaning device 200 along the length direction of the material picking device 100. The fixed end of the first lifting structure 210 is connected to the material picking device 100, and the movable end of the first lifting structure 210 is connected to the tank cleaning device 200. The movable end of the first lifting structure 210 is suitable for telescopic movement relative to the fixed end of the first lifting structure 210.

[0097] Specifically, Figure 3 , Figure 6 As shown, by arranging a first lifting structure 210 between the material taking device 100 and the tank cleaning device 200, the telescopic effect of the first lifting structure 210 is used to adjust the relative positions of the tank cleaning device 200 and the material taking device 100, so that the tank cleaning device 200 is away from the bottom material taking position of the material taking device 100 when it is not needed to work, and the height difference between the bottom position of the tank cleaning device 200 and the bottom material taking position of the material taking device 100 is increased, so as to avoid the tank cleaning device 200 from contacting part of the materials on the side of the material taking device 100 and pushing the materials away when the material taking device 100 is operating normally, thereby ensuring that the material taking device 100 can take materials normally.

[0098] On the basis of the above implementation manner, as a further limited implementation manner, Figure 3 , Figure 6 As shown, the movable end of the first lifting structure 210 is rotatably connected to the side of the tank cleaning device 200 close to the material picking device 100; the material picking system also includes a second lifting structure 211, which is arranged between the material picking device 100 and / or the first lifting structure 210 and the tank cleaning device 200, the fixed end of the second lifting structure 211 is connected to the material picking device 100 and / or the fixed end of the first lifting structure 210, the movable end of the second lifting structure 211 is rotatably connected to the side of the tank cleaning device 200 away from the material picking device 100, and the movable end of the second lifting structure 211 is suitable for telescopic movement relative to the fixed end of the second lifting structure 211, thereby driving the tank cleaning device 200 to a second expanded state away from the material picking device 100, or a second retracted state retracted toward the material picking device 100.

[0099] Specifically, the movable end of the first lifting structure 210 is rotatably connected to the side of the cleaning device 200 close to the material taking device 100. When the second lifting structure 211 produces a telescopic effect, the cleaning device 200 and the material taking device 100 are adjusted to rotate around the rotation connection. Figure 3 From the perspective of the embodiment of the present invention, the cleaning device 200 rotates upward to switch from the second deployed state to the second retracted state.

[0100] Furthermore, since the fixed end of the first lifting structure 210 is fixedly connected to the material picking device 100, in the scheme for ensuring that the fixed end of the second lifting structure 211 is in a fixed state, the fixed end of the second lifting structure 211 can be connected to the material picking device 100, or the fixed end of the second lifting structure 211 can be connected to the fixed end of the first lifting structure 210, so as to ensure that the fixed end of the second lifting structure 211 is in a fixed state.

[0101] Furthermore, this embodiment does not limit the specific structural form of the first lifting structure 210 and the second lifting structure 211, as long as they can complete the telescopic effect. The specific structural form of the first lifting structure 210 and the second lifting structure 211 can be a telescopic cylinder, a reel cable, etc.

[0102] On the basis of the above implementation manner, as a further limited implementation manner, Figure 3 , Figure 5 , Figure 6 As shown, the tank cleaning device 200 is arranged on two opposite sides of the material taking device 100 .

[0103] Specifically, four side walls are formed on the material taking device 100 along the length direction, and the tank cleaning device 200 is arranged on two opposite side walls of the material taking device 100 to collect materials on the corresponding two sides of the material taking device 100, thereby improving the material cleaning efficiency.

[0104] On the basis of the above implementation manner, as a further limited implementation manner, Figure 3 As shown, two tank cleaning devices 200 are arranged side by side on one side of the material taking device 100 .

[0105] Specifically, two tank cleaning devices 200 are arranged side by side on a side wall of the material taking device 100, and work simultaneously to collect materials and improve the efficiency of material cleaning.

[0106] On the basis of the above implementation manner, as a further limited implementation manner, Figure 3 As shown, the first lifting structure 210 is a telescopic cylinder, the fixed end of the telescopic cylinder is hinged to the material taking device 100 through a fixed hinge point 212, and the movable end of the first lifting structure 210 is hinged to the side of the cleaning device 200 close to the material taking device 100 through a movable hinge point 213.

[0107] Specifically, Figure 3As shown, in an installation structure of a tank cleaning device 200, two fixed hinges 212 are arranged in the length direction of the material taking device 100, and the fixed end of the telescopic cylinder is hinged and fixed at two positions to ensure the stability of the fixed position of the fixed end of the telescopic cylinder; the movable end of the first lifting structure 210 is hinged to the side of the tank cleaning device 200 close to the material taking device 100 through the movable hinge 213, and the movable end of the first lifting structure 210 is rotatably connected to the side of the tank cleaning device 200 close to the material taking device 100 through the movable hinge 213, thereby ensuring the switching operation of the tank cleaning device 200 between the second deployed state and the second retracted state.

[0108] On the basis of the above implementation manner, as a further limited implementation manner, Figure 3 , Figure 6 As shown, the second lifting structure 211 includes: a lifting reel 2111, a cabin cleaning connecting rope 2112 and a driving motor.

[0109] The lifting reel 2111 is connected to the fixed end of the material taking device 100 and / or the first lifting structure 210, and the lifting reel 2111 is connected to the reel driving motor power.

[0110] One end of the tank cleaning connecting rope 2112 is wound around the lifting reel 2111 , and the other end is connected to a side of the tank cleaning device 200 away from the material taking device 100 .

[0111] Specifically, the lifting reel 2111, as the fixed end of the second lifting structure 211, is fixedly connected to the fixed end of the material picking device 100 or the first lifting structure 210. Under the driving action of the reel driving motor on the lifting reel 2111, the lifting reel 2111 rotates to wind the tank cleaning connecting rope 2112 around the outer wall of the lifting reel 2111 or releases the tank cleaning connecting rope 2112, so that the tank cleaning connecting rope 2112 is shortened or lengthened, thereby switching the tank cleaning device 200 connected to the tank cleaning connecting rope 2112 between the second unfolded state and the second retracted state.

[0112] On the basis of the above implementation manner, as a further limited implementation manner, Figure 3 As shown, the tank cleaning device 200 includes: a mounting frame 201, a spiral sheet 202, a tank cleaning drive motor 203, etc.

[0113] The mounting frame 201 has one end rotatably connected to the movable end of the first lifting structure 210 , and the other end rotatably connected to the movable end of the second lifting structure 211 .

[0114] The spiral blade 202 is rotatably connected to the mounting frame 201 . After the spiral blade 202 rotates, it is suitable for gathering the materials in the direction close to the material taking device 100 .

[0115] The cabin cleaning drive motor 203 is connected to the spiral blade 202 in power.

[0116] Specifically, the spiral blade 202 pushes the material under the driving action of the cleaning drive motor 203, and the material moves along the extension direction of the spiral line of the spiral blade 202. Under the reasonable steering setting of the cleaning drive motor 203, the material is collected close to the material taking device 100, thereby realizing the cleaning operation.

[0117] On the basis of the above implementation manner, as a further limited implementation manner, Figure 3 , Figure 5 As shown, the tank cleaning device 200 further includes a support assembly 204 connected to the mounting frame 201 , and the bottom height position of the support assembly 204 is not lower than the bottom height position of the spiral sheet 202 .

[0118] Specifically, after the cleaning device 200 is lowered, the support assembly 204 forms a supporting effect on the top of the material or the bottom of the cabin. When the terrain is undulating, the support assembly 204 is always close to the lower surface, driving the cleaning device 200 to follow the terrain, so that the cleaning device 200 can adapt to different cabin environments and is also convenient for moving with the main material taking device. At the same time, the bottom height position of the support assembly 204 is slightly lower than the bottom height position of the spiral blade 202, which maximizes the cleaning efficiency of the spiral blade 202 while preventing the spiral blade 202 from interfering with the cabin bottom wall plate during operation and causing damage.

[0119] On the basis of the above implementation manner, as a further limited implementation manner, Figure 3 , Figure 5 As shown, the support assembly 204 includes a support wheel 205 , and the support wheel 205 is arranged along the movement direction of the material taking device 100 .

[0120] Specifically, after the cleaning device is lowered, the support wheels 205 are arranged so that the support wheels 205 roll on the top of the material or the bottom of the cabin, thereby improving the smoothness of the movement of the cleaning device 200. At the same time, in view of the different arrangement modes of the reclaiming device 100 and the cleaning device 200 on different side walls of the reclaiming device 100, the support wheels 205 are arranged along the movement direction of the reclaiming device 100, so that the support wheels 205 are suitable for rolling along the movement direction of the reclaiming device 100, thereby facilitating the synchronous movement of the cleaning device 200 and the reclaiming device 100.

[0123] Specifically, Figure 7 As shown, the ship unloader 1 is arranged on the dock foundation 4, the cabin 2 loaded with materials 3 is located on one side of the dock foundation 4, and the material taking device 100 moves along the main beam 20 to dig the materials 3 using the chain bucket.

[0124] Furthermore, as the implementation carrier of the material reclaiming system, the ship unloader naturally has all the advantages of the material reclaiming system, which will not be elaborated here.

[0125] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
