[0001] The present invention relates to the technical field of ship unloading mechanical devices, and in particular to a pusher rake device and a ship unloader. Background Art

[0002] Ship unloaders are equipment used for loading and unloading bulk materials. Continuous ship unloaders have a long history of use at bulk cargo unloading terminals in ports. Bucket chain ship unloaders, in particular, have gained widespread adoption due to their environmentally friendly performance and ability to stably transport materials during unloading.

[0003] The hatch of the ship's hold is usually equipped with a coaming, but since the rigid chain bucket arm cannot extend under the hatch coaming of the bulk carrier, the material under the hatch coaming is difficult to unload, resulting in a large amount of cargo to be cleared when using the chain bucket ship unloader, seriously affecting the overall efficiency. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that materials under the hatch coaming are difficult to unload, thereby providing a pusher and rake device that can easily unload materials under the hatch coaming.

[0005] Another technical problem to be solved by the present invention is to overcome the defect in the prior art that materials below the hatch coaming are difficult to unload, thereby providing a ship unloader that can easily unload materials below the hatch coaming.

[0006] In order to solve the above technical problems, the present invention provides a push-rake device, which is suitable for being movably mounted on the reclaiming end of the reclaiming device; the push-rake device comprises:

[0007] A connecting rod, hingedly connected to the material taking device;

[0008] A pusher head is provided at the end of the connecting rod away from the material taking device;

[0009] The connecting rod has a retracted state at a first preset angle A to the vertical plane, and an extended state at a second preset angle B to the vertical plane, wherein A<B.

[0010] Optionally, the pusher head is hingedly connected to the connecting rod; in the retracted state, the angle between the plane where the pusher head is located and the connecting rod is C; in the expanded state, the angle between the plane where the pusher head is located and the connecting rod is D, wherein C<D.

[0011] Optionally, the rake pushing device further comprises: a rake pushing head oil cylinder, one end of which is fixed to the connecting rod and hingedly connected to the connecting rod, and the other end of which is hingedly connected to the rake pushing head, wherein the rake pushing head oil cylinder is suitable for driving the rake pushing head to rotate relative to the connecting rod.

[0012] Optionally, the push rake device also includes: a connecting rod cylinder, one end of which is fixed to the material picking device and hingedly connected to the material picking device, and the other end is hingedly connected to the connecting rod, and the connecting rod cylinder is suitable for driving the connecting rod to rotate relative to the material picking device.

[0013] Optionally, the value range of the first preset angle A is 0°≤A<45°.

[0014] Optionally, the value range of the second preset angle B is 45°≤B≤135°.

[0015] Optionally, the value of the second preset angle B is B=90°.

[0016] The ship unloader provided by the present invention comprises:

[0017] Reclaiming device;

[0018] And the push rake device as described above is arranged at the material taking end of the material taking device.

[0019] Optionally, a plurality of push-rake devices are arranged circumferentially around the material taking device.

[0020] Optionally, the push-rake device is respectively arranged on both sides of the reclaiming device along the width direction of the ship;

[0021] And / or, the push-rake device is respectively arranged on both sides of the material taking device along the length direction of the ship.

[0022] The technical solution of the present invention has the following advantages:

[0023] 1. The pusher-rake device provided by the present invention is movably mounted on the reclaiming end of the reclaiming device and has a retracted state at a first preset angle A to the vertical plane and an extended state at a second preset angle B to the vertical plane, wherein A<B; thus, in the retracted state, the pusher-rake device can be folded up to facilitate the reclaiming device to extend into the cabin while preventing interference with the normal operation of the reclaiming device; and in the extended state, the pusher-rake device can be spread out to facilitate the pusher-rake device to extend under the hatch coaming to scrape the material under the hatch coaming, thereby facilitating the reclaiming device to reclaim the material, thereby reducing the amount of tank cleaning required by the reclaiming device and improving the overall unloading efficiency.

[0024] 2. The pusher-rake device provided by the present invention hinges the pusher-rake head to the connecting rod, enabling the pusher-rake head to adjust its angle relative to the connecting rod. This facilitates the removal of materials from corners and allows for smaller areas of material removal, facilitating the collection of materials without requiring translational movement of the entire reclaiming device. Furthermore, if material adheres to the bulkhead, the pusher-rake head can be controlled to strike the material back and forth perpendicularly to the bulkhead, dislodging it. This provides greater flexibility in tank clearing and improves efficiency.

[0025] 3. The ship unloader provided by the present invention is provided with a pusher and rake device at the retrieving end of the retrieving device, so that the pusher and rake device can be put away in the retracted state, which makes it convenient for the retrieving device to extend into the interior of the cabin and prevents interference with the normal operation of the retrieving device; and in the unfolded state, the pusher and rake device is spread out, which makes it convenient for the pusher and rake device to extend under the hatch coaming to pick up the materials under the hatch coaming, making it convenient for the retrieving device to pick up the materials, thereby reducing the amount of cabin cleaning when using the retrieving device to clean the cabin and improving the overall efficiency of unloading.

[0038] 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.

[0039] Example 1

[0040] Combine Figures 1-4 As shown, the pusher and rake device provided in this embodiment is suitable for being movably mounted on the reclaiming end of the reclaiming device 100; the pusher and rake device 700 includes:

[0041] The connecting rod 703 is hingedly connected to the material taking device 100;

[0042] The pusher head 701 is provided at the end of the connecting rod 703 away from the material taking device 100;

[0043] The connecting rod 703 has a retracted state at a first preset angle A with the vertical plane, and an extended state at a second preset angle B with the vertical plane, wherein A<B.

[0044] Preferably, the push-and-rake device 700 is mounted on the reclaiming device 100 and is adapted to follow the reclaiming device 100 in performing lifting or translational movements. In the retracted state, the push-and-rake device 700 is placed against the housing of the reclaiming device 100, facilitating the reclaiming device 100 from extending into the cabin while preventing interference with the normal operation of the reclaiming device 100. In the deployed state, the projected coverage area of ​​the push-and-rake device 700 on the horizontal plane is larger than the projected coverage area of ​​the reclaiming device 100 on the horizontal plane, and the push-and-rake device 700 is mounted at the reclaiming end of the reclaiming device 100, thereby being able to conveniently extend under the hatch coaming and scrape the material under the hatch coaming to a place where the reclaiming device 100 can reach it, thereby facilitating the reclaiming device 100 to carry out material reclaiming.

[0045] The pusher and rake device provided in this embodiment is movably installed on the retrieving end of the retrieving device 100, and has a retracted state at a first preset angle A to the vertical plane, and an expanded state at a second preset angle B to the vertical plane, wherein A<B; thereby, in the retracted state, the pusher and rake device 700 can be folded up, making it convenient for the retrieving device 100 to extend into the interior of the cabin while preventing interference with the normal operation of the retrieving device 100; and in the expanded state, the pusher and rake device 700 can be spread out, making it convenient for the pusher and rake device 700 to extend under the hatch coaming to pick up the material under the hatch coaming, thereby facilitating the retrieving device 100 to pick up the material, thereby reducing the amount of cabin cleaning using the retrieving device 100 and improving the overall unloading efficiency.

[0046] Specifically, the pusher head 701 is hingedly connected to the connecting rod 703 .

[0047] The pusher and rake device provided in this embodiment, by hingedly connecting the pusher and rake head 701 to the connecting rod 703, can adjust the angle of the pusher and rake head 701 relative to the connecting rod 703. This allows the pusher and rake head 701 to easily pick up materials from corners. When the entire reclaiming device 100 does not need to perform translational motion, it can also pick up materials in a small area, making it easier to gather materials. Furthermore, when materials adhere to the bulkhead, the action of the two oil cylinders can be controlled to cause the pusher and rake head to strike the materials back and forth perpendicularly to the bulkhead, causing the materials to fall off the bulkhead. This provides a more flexible and efficient way to clear the tank.

[0048] Preferably, in the retracted state, the angle between the plane of the pusher head 701 and the connecting rod 703 is C; in the extended state, the angle between the plane of the pusher head 701 and the connecting rod 703 is D, where C < D. By making the angle of the pusher head 701 smaller when the connecting rod 703 is in the retracted state than when the connecting rod 703 is in the extended state, the vertical space occupied by the pusher head 701 is reduced, facilitating the overall lifting and lowering of the reclaiming device 100 and avoiding interference with the cabin coaming.

[0049] Specifically, the pushing rake device 700 also includes: a pushing rake head cylinder 702, one end of which is fixed on the connecting rod 703 and hingedly connected to the connecting rod 703, and the other end is hingedly connected to the pushing rake head 701. The pushing rake head cylinder 702 is suitable for driving the pushing rake head 701 to rotate relative to the connecting rod 703.

[0050] Preferably, the rake pushing head oil cylinder 702 can control the pitch angle of the rake pushing head 701 to achieve the pushing and raking of materials under different working conditions.

[0051] Specifically, the pushing rake device 700 also includes: a connecting rod cylinder 704, one end of which is fixed on the material picking device 100 and hingedly connected to the material picking device 100, and the other end is hingedly connected to the connecting rod 703. The connecting rod cylinder 704 is suitable for driving the connecting rod 703 to rotate relative to the material picking device 100.

[0052] The connecting rod oil cylinder 704 can control the pitch angle of the connecting rod 703, thereby controlling the position of the pusher head.

[0053] Preferably, a cover is provided on the outside of the material taking device 100, and the connecting rod is connected to the cover of the material taking device through a hinge point. One end of the connecting rod cylinder 704 is hinged to the cover of the material taking device, and the other end is hinged to the connecting rod.

[0054] Specifically, the value range of the first preset angle A is 0°≤A<45°.

[0055] Specifically, the value range of the second preset angle B is 45°≤B≤135°.

[0056] Specifically, the value of the second preset angle B is B=90°.

[0057] By controlling the first preset angle A and the second preset angle B, the connecting rod 703 can be switched between the retracted state and the extended state, thereby adjusting the projection coverage area of ​​the push-rake device 700 on the horizontal plane.

[0058] Example 2

[0059] Combine Figure 1 As shown, this embodiment provides a ship unloader, comprising:

[0060] Reclaiming device 100;

[0061] And the pushing and rake device 700 as described in the above embodiment 1 is arranged at the material retrieving end of the material retrieving device 100.

[0062] The ship unloader provided in this embodiment is provided with a pusher and rake device 700 at the retrieving end of the retrieving device 100, so that the pusher and rake device 700 can be folded up in the retracted state, making it convenient for the retrieving device 100 to extend into the interior of the cabin and preventing interference with the normal operation of the retrieving device 100; and in the unfolded state, the pusher and rake device 700 is spread out, making it convenient for the pusher and rake device 700 to extend under the hatch coaming to pick up the material under the hatch coaming, making it convenient for the retrieving device 100 to pick up the material, thereby reducing the amount of tank cleaning when using the retrieving device 100 to clean the cabin and improving the overall unloading efficiency.

[0063] Optionally, the ship unloader is arranged on the dock foundation 40, and the dock foundation 40 is provided with a track, and the ship unloader can move along the track to drive the frame body of the ship unloader to move along the track.

[0064] Optionally, the frame body 10 further includes a main beam 12 and a trolley 13 adapted to move horizontally relative to the main beam 12. The reclaiming device 100 is driven by the trolley 13, thereby moving horizontally along the main beam 12. The trolley 13 can move the reclaiming device 100 above the cabin 20 to unload the material 30 in the cabin 20. The reclaiming device 100 includes a hopper chain 110 for scooping material.

[0065] The following describes the specific operating process of the ship unloader provided by this embodiment in detail: When the reclaimer 100 needs to unload material from beneath the hatch coaming of a bulk cargo ship, but the reclaimer 100 cannot extend beneath the hatch coaming, the pusher and rake device 700 provided by this embodiment and the first embodiment can be used. First, the pusher and rake device 700 is retracted, placed against the cover of the reclaimer 100, facilitating the reclaimer 100's extension into the ship's hold while preventing interference with the normal operation of the reclaimer 100. Once the reclaimer 100 is extended into the ship's hold, the pusher and rake head cylinder 702 and the connecting rod cylinder 704 on the pusher and rake device 700 work in tandem. The connecting rod cylinder 704 adjusts the overall position and height of the pusher and rake device, controlling its extension beneath the hatch coaming. The pusher and rake head cylinder 702 adjusts the posture of the pusher and rake head to accommodate the material in different situations. This allows the pusher and rake device 700 to follow the movement of the reclaimer 100, effectively pushing and raking the material beneath the hatch coaming. Furthermore, when material adheres to the bulkhead, the two oil cylinders can be controlled to cause the pusher rake head to strike the material back and forth perpendicularly to the bulkhead, causing it to fall off. The pusher rake device 700 then rakes the material to the hatch, facilitating its retrieval by the chain bucket ship unloader. This significantly reduces the amount of cargo to be cleared and improves overall unloading efficiency.

[0066] Specifically, a plurality of push-rake devices 700 are circumferentially arranged around the material taking device 100 .

[0067] Preferably, each pusher and rake device can be controlled and operated independently. When it is necessary to clean the materials below the hatch coaming in a certain direction, the pusher and rake device in the corresponding direction is extended, and the other pusher and rake devices continue to be in a retracted state.

[0068] Specifically, the push-rake device 700 is respectively arranged on both sides of the reclaiming device 100 along the ship width direction;

[0069] And / or, the push-rake device 700 is respectively arranged on both sides of the material taking device 100 along the length direction of the ship.

[0070] It should be noted that, combined with Figure 1 As shown, the ship width direction refers to Figure 1 The left and right directions of the middle cabin 20, the length direction refers to Figure 1 In the direction perpendicular to the paper.

[0071] Preferably, a set of pushing and rake mechanisms is installed on each of the four surfaces of the cover shell of the material taking device.

[0072] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
