Description

Technical Field

[0001] The invention relates to the field of forklift anti-collision, and in particular to an anti-collision device for a port forklift. Background Art

[0002] Forklifts are equipment used for operations in narrow passages and limited spaces, and are mostly used in ports, railways, freight yards, warehouses and other places containing explosive mixtures.

[0003] When the forklift is used in the port, there will be support parts on the port ground for supporting the goods. After the goods are transferred, the remaining support parts will become obstacles if they are not handled in time. Especially when reversing, when there are obstacles at the rear, obstacles lower than the forklift chassis are easy to come under the forklift chassis. After the collision, the obstacles are easy to approach the wheels from the side, and the wheels will be lifted up during the rolling process, causing the center of gravity of the vehicle body to change, which can easily cause rollover and pose a safety hazard. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings in the prior art and to propose an anti-collision device for a port forklift.

[0005] To achieve the above purpose, a certain technical solution adopted by the present invention is: an anti-collision device for a port stacker, comprising a distance sensor, a camera unit and an anti-collision component, wherein the anti-collision component comprises

[0006] A first anti-collision body is arranged at the rear end of the body of the forklift;

[0007] a second anti-collision body, the second anti-collision body being arranged below the first anti-collision body, the second anti-collision body comprising a height adjustment unit and an anti-collision piece, the height of the anti-collision piece being adjusted by the height adjustment unit to adapt to the impact of an obstacle close to the ground;

[0008] A third anti-collision body is arranged at positions corresponding to the wheels on both sides of the tail of the stacker, and the third anti-collision body includes an anti-collision baffle and an angle adjustment unit. The anti-collision baffle is used to prevent the moving obstacle from entering the wheels of the stacker, and the angle adjustment unit is used to adjust the blocking angle of the anti-collision baffle;

[0009] The pushing unit is used to push and clear obstacles at the tail of the forklift;

[0010] In the process of the pushing unit pushing the obstacle, the obstacle moving to the wheels of the forklift is blocked and guided in a coordinated manner with the adjusted protection angle of the third anti-collision body, so that the moving obstacle avoids the wheels.

[0011] Specifically, when the forklift moves backward to adjust its position, if there is an obstacle behind it, the distance sensor will detect the relative distance of the obstacle in front of it, and combine the image information collected by the camera unit to detect the obstacle in time and observe the obstacle. The following scenarios may exist:

[0012] In the first scenario, when the obstacle is a car, pedestrian, wall or other obstacle that is higher than the chassis of the forklift like the car body, the distance sensor and the camera unit will identify it, and the operator will take timely measures through the information displayed on the display end to avoid collision. If the operation is not timely and a collision occurs, the first anti-collision body, the second anti-collision body and the third anti-collision body can all provide protection. The first anti-collision body and the second anti-collision body will provide pressure protection for the rear end of the forklift. The third anti-collision body is located at the position of the rear wheels of the forklift, and can protect against side collisions when the forklift reverses and turns, which is beneficial to avoid damage to the wheels. The entire protection system can provide adaptive protection for the scene when the forklift reverses, which is beneficial to improve the protection effect on the rear end of the forklift.

[0013] In the second scenario, when the obstacle is debris and its height is lower than the chassis of the forklift or close to the height of the chassis, the height adjustment unit is controlled to adjust the height of the anti-collision part and adjust the anti-collision part close to the ground to adapt to the height of the debris, and the pushing unit is controlled to push the debris to push the debris away from the rear end of the forklift to ensure that the forklift can reverse and adjust smoothly. There is no need for the operator to clean up the debris, but only need to push it away temporarily and then inform the site cleaning personnel to clean it up, which is conducive to reducing the impact on the progress of the stacking work.

[0014] In the third scenario, when the debris is being pushed away by the pushing unit, if the debris moves and avoids the pushing unit and moves closer to the side of the wheel due to the terrain and its own inertia, the anti-collision baffle of the third anti-collision body will adjust the protection angle through the angle adjustment unit during the pushing process. As shown in the figure, the first pushing member and the anti-collision baffle on one side of the forklift present a protective state. When the debris collides, on the one hand, it can provide support to prevent the debris from colliding with the wheel. On the other hand, it can be tilted to guide the debris to a position away from the wheel, further improving the protection effect on the rear end of the forklift.

[0015] As a preferred technical solution, the first anti-collision body specifically includes an anti-collision cover, and the anti-collision cover is fixedly installed at the rear end of the forklift body.

[0016] It should be understood that by setting the first anti-collision body as an anti-collision cover, on the one hand, it is beneficial to reduce the material consumption of the first anti-collision body, and on the other hand, it provides installation space for the anti-collision mechanism at the rear end of the forklift, reduces the occupancy of the rear end space of the forklift, avoids increasing the length of the entire vehicle body due to protection, and reduces the requirements for mobile space.

[0017] As a preferred technical solution, the anti-collision member specifically includes

[0018] An anti-collision beam, a support frame is fixedly installed on the top of the anti-collision beam, and the support frame is slidably installed on the rear end of the body of the forklift through a track, and the height difference with the bottom surface is adjusted by the height adjustment unit.

[0019] Specifically, by setting the anti-collision beam, when the debris is lower than or close to the height of the forklift chassis, the height of the anti-collision beam can be adjusted, and the bottom of the forklift can be shielded and protected by the anti-collision beam, which is helpful to prevent the debris from entering under the forklift chassis.

[0020] As a preferred technical solution, the anti-collision baffle also includes

[0021] A fixing seat, the fixing seat being fixedly mounted at a position near the end of the bottom of the anti-collision member;

[0022] Two sliding seats, the two sliding seats are slidably installed on the fixed seat and the ends are rotatably connected to the anti-collision baffle through connecting pieces, and the rotation angle of the sliding seat and the anti-collision baffle is limited by the ends of the sliding seat, and an elastic support piece is arranged between the sliding seat and the fixed seat.

[0023] Specifically, when colliding with moving debris, the anti-collision baffle plate and the entire sliding seat will squeeze the elastic support member, and the elastic support member will undergo elastic deformation to buffer the impact force, thereby buffering the impact force received by the anti-collision baffle plate and helping to reduce the damage caused by rigid collision.

[0024] As a preferred technical solution, the connecting piece includes

[0025] A first mounting cavity, the first mounting cavity is opened at the end of the sliding seat, a connecting shaft is fixedly connected in the first mounting cavity, a rotating member is rotatably connected to the surface of the connecting shaft, and the rotating member is fixedly connected to the anti-collision baffle;

[0026] An angle maintaining component, the angle maintaining component includes an arc groove, a limit block and a support spring, the arc groove is opened on the rotating part, the limit block is fixedly connected to the surface of the connecting shaft, and the limit block is connected to the inner wall of the arc groove through a support spring to realize elastic support for the connection state of the rotating part and the connecting shaft.

[0027] Specifically, when the anti-collision baffle is not adjusted in angle, the relative position of the limit block in the arc groove is maintained by the support of the support spring, thereby maintaining the anti-collision baffle in a stored state. While providing protection, it reduces the impact on the side space of the forklift. In this state, the non-protective surface of the anti-collision baffle can contact the end of the sliding seat to form a support, thereby reducing dependence on rotating parts.

[0028] As a preferred technical solution, the angle adjustment unit includes

[0029] A linkage block, the linkage block being fixedly connected to a side surface of the rotating member;

[0030] A push plate, the push plate is slidably inserted on the fixing seat and contacts the linkage block;

[0031] A pushing power member is used to push the pushing plate to push the linkage block during the process of adjusting the angle of the anti-collision baffle, thereby rotating the linkage block and the rotating member as a whole relative to the connecting shaft to achieve angle adjustment of the anti-collision baffle.

[0032] Specifically, when debris is detected to be lower than the chassis of the forklift, the power part is pushed to move the pushing plate, which will push the linkage block. The linkage block and the overall relative connecting shaft of the rotating part will rotate, and then the anti-collision baffle will be flipped synchronously to block the moving debris. The blocking angle can limit the moving direction of the debris, so that the debris will turn away from the wheel as it continues to move.

[0033] Further explanation, the pushing plate is slidably inserted into the sliding seat at the same time. After the pushing plate is pushed, the side of the pushing plate is fitted with the side of the linkage block to achieve limited support. When the anti-collision baffle encounters a collision, the linkage block will act on the side of the pushing plate without causing a reaction force on the pushing power part.

[0034] As a preferred technical solution, the pushing unit includes

[0035] a second mounting cavity, the second mounting cavity being opened at the bottom end of the anti-collision member;

[0036] Two first pushing members are symmetrically rotatably connected in the second installation cavity, and a first flip adjustment component is connected between the first pushing members and the inner wall of the second installation cavity.

[0037] Specifically, when it is detected that the debris at the rear end of the forklift is lower than or close to the height of the forklift chassis, the first flip adjustment component is used to adjust the first pushing member to flip, so as to move the debris at the rear end of the forklift, drive the debris to a position away from the rear end of the forklift, and drive the debris to the oblique rear on both sides of the forklift, which is conducive to moving the debris away from the forklift and providing favorable space for the next step of movement.

[0038] As a preferred technical solution, the pushing unit also includes

[0039] The second pushing member is rotatably connected to the surface of the first pushing member, and the pushing angle formed relative to the first pushing member is adjusted by a second flip adjustment component arranged in the second mounting cavity, so as to further push the debris on the ground to a direction away from the forklift body.

[0040] Specifically, the first flip adjustment component is a third electric cylinder, and two ends of the third electric cylinder are rotatably connected to the first pushing member and the inner wall of the second installation cavity respectively.

[0041] It should be understood that, by providing the third electric cylinder, the flipping state of the first pushing member can be adjusted, thereby providing power for the flipping of the first pushing member.

[0042] As a preferred technical solution, the second flip adjustment component includes

[0043] A pushing track, the pushing track is fixedly connected to a side of the second pushing member away from the pushing surface, the pushing track comprising a second inclined groove and a straight groove;

[0044] A sliding plate, the sliding plate being slidably connected to a side of the first pushing member away from the pushing surface, and a linkage column slidably arranged in the second inclined groove is fixedly connected to the surface of the sliding plate;

[0045] A pulling rod, one end of which is rotatably connected to the end of the sliding plate, and the other end of which is rotatably connected to the inner wall of the second mounting cavity.

[0046] It should be understood that when debris is caught below the chassis of the forklift or close to the chassis of the forklift, in the process of pushing the debris obliquely rearward by the first pushing member, the sliding plate will slide relative to the first pushing member under the limited pulling of the pulling rod, and the sliding plate will simultaneously drive the linkage column to move in the second inclined groove to push the second pushing member. The second pushing member will flip over and push the debris pushed by the first pushing member further obliquely rearward, thereby further adjusting the pushing angle. On the one hand, it is beneficial to push the debris away from the tail end of the forklift, and on the other hand, it prevents the first pushing member from further increasing its flipping angle and driving the debris to move toward the side direction of the forklift.

[0047] Compared with the prior art, the present invention has the following beneficial effects:

[0048] According to the present invention, the first anti-collision body and the second anti-collision body can provide pressure protection for the rear end of the forklift, and the third anti-collision body is located at the position of the rear wheels of the forklift, which can protect the side collision when the forklift is reversed and turned, which is beneficial to avoid damage to the wheels. The entire protection system can provide adaptive protection for the scene when the forklift is reversed, which is beneficial to improve the protection effect on the rear end of the forklift.

[0049] When the obstacle is debris and its height is lower than the chassis of the forklift or close to the height of the chassis, the height adjustment unit is controlled to adjust the height of the anti-collision part and adjust the anti-collision part close to the ground to adapt to the height of the debris, and the pushing unit is controlled to push the debris to push the debris away from the rear end of the forklift, ensuring that the forklift can be reversed and adjusted smoothly. The operator does not need to clean up the debris, but only needs to push it away temporarily and then inform the site cleaning personnel to clean it up, which is conducive to reducing the impact on the progress of the stacking work.

[0050] By providing a second pushing member, the debris pushed by the first pushing member is further pushed obliquely rearward, thereby achieving further adjustment of the pushing angle. On the one hand, it is beneficial to push the debris away from the rear end of the forklift, and on the other hand, it prevents the first pushing member from further increasing its flipping angle and driving the debris to move to the side direction of the forklift.

DETAILED DESCRIPTION

[0063] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0064] like Figures 1 to 11 The anti-collision device of a port stacker 6 shown in the figure comprises a distance sensor 1, a camera unit 2 and an anti-collision component, wherein the anti-collision component comprises

[0065] A first anti-collision body 3 is arranged at the rear end of the body of the stacker 6;

[0066] A second anti-collision body, which is arranged below the first anti-collision body 3, and includes a height adjustment unit and an anti-collision piece. The height of the anti-collision piece is adjusted by the height adjustment unit to adapt to the impact of an obstacle close to the ground;

[0067] The third anti-collision body is arranged at the positions corresponding to the wheels on both sides of the tail of the stacker 6. The third anti-collision body includes an anti-collision baffle 5 and an angle adjustment unit. The anti-collision baffle 5 is used to prevent the moving obstacles from entering the wheels of the stacker 6. The angle adjustment unit is used to adjust the blocking angle of the anti-collision baffle 5;

[0068] A pushing unit, used to push and clear obstacles at the tail of the forklift 6;

[0069] In the process of the pushing unit pushing the obstacle, the obstacle moving to the wheel of the stacker 6 is blocked and guided in the coordinated state of the protection angle of the third anti-collision body so as to avoid the wheel.

[0070] As an optional embodiment, there are multiple distance sensors 1, which can be specifically radar sensors, which are respectively installed on the nose of the forklift 6 and the outer surface of the first anti-collision body 3, to detect the distance between the nose and the tail of the forklift 6 and the obstacle respectively, and if they are close, the distance information is fed back in time.

[0071] As an optional embodiment, the camera unit 2 is specifically a camera, which is fixedly installed on the top of the first anti-collision body 3 and is used to monitor the distribution of obstacles at the rear end of the forklift 6 in real time and feedback the monitoring information in time.

[0072] Specifically, when the stacker 6 moves backward to adjust its position, if there is an obstacle behind, the distance sensor 1 will detect the relative distance of the obstacle in front, and in combination with the collection of image information by the camera unit 2, the obstacle will be discovered in time and observed. The following scenarios may occur:

[0073] In the first scenario, when the obstacle is a car, pedestrian, wall or other obstacle that is higher than the chassis of the stacker 6 such as the car body, the distance sensor 1 and the camera unit 2 will identify it, and the operator will take timely measures through the information displayed on the display end to avoid collision. If the operation is not timely and a collision occurs, the first anti-collision body 3, the second anti-collision body and the third anti-collision body can all provide protection. The first anti-collision body 3 and the second anti-collision body will provide pressure protection for the rear end of the stacker 6. The third anti-collision body is located at the position of the rear wheels of the stacker 6, and can protect the stacker 6 from side collisions when reversing and turning, which is beneficial to avoid damage to the wheels. The entire protection system can provide adaptive protection for the scene when the stacker 6 is reversing, which is beneficial to improve the protection effect of the rear end of the stacker 6.

[0074] In the second scenario, when the obstacle is debris and its height is lower than the chassis of the forklift 6 or close to the height of the chassis, the height adjustment unit is controlled to adjust the height of the anti-collision part and adjust the anti-collision part close to the ground to adapt to the height of the debris, and the pushing unit is controlled to push the debris to push the debris away from the rear end of the forklift 6 to ensure that the forklift 6 can be reversed and adjusted smoothly. There is no need for the operator to clean up the debris, but only need to push it away temporarily and then inform the site cleaning personnel to clean it up, which is conducive to reducing the impact on the progress of the stacking work.

[0075] In the third scenario, when the debris is pushed away by the pushing unit, if the debris moves and avoids the pushing unit and moves closer to the side of the wheel due to the terrain and its own inertia, the anti-collision baffle 5 of the third anti-collision body will adjust the protection angle of the anti-collision baffle 5 through the angle adjustment unit during the pushing process, such as Fig.11 As shown, the first pushing member 22 and the anti-collision baffle 5 on one side of the forklift 6 are in a protective state. When debris collides with the anti-collision baffle 5, the anti-collision baffle 5 can provide support on the one hand to prevent the debris from colliding with the wheels, and on the other hand, it can be tilted to guide the debris to a position away from the wheels, thereby further improving the protection effect on the rear end of the forklift 6.

[0076] As a further optimized embodiment, the first anti-collision body 3 specifically includes an anti-collision cover, and the anti-collision cover is fixedly installed at the rear end of the body of the stacker 6.

[0077] It should be understood that by setting the first anti-collision body 3 as an anti-collision cover, on the one hand, it is beneficial to reduce the material consumption of the first anti-collision body 3, and on the other hand, it provides installation space for the anti-collision mechanism at the rear end of the forklift 6, reduces the occupation of the rear end space of the forklift 6, avoids increasing the length of the entire vehicle body due to protection, and reduces the requirement for mobile space.

[0078] As a further optimized embodiment, the anti-collision member specifically includes

[0079] The anti-collision beam 4 has a support frame 7 fixedly mounted on the top thereof. The support frame 7 is slidably mounted on the rear end of the body of the stacker 6 through a track, and the height difference with the bottom surface is adjusted through a height adjustment unit.

[0080] As an optional embodiment, the height adjustment unit is specifically a first electric cylinder 30 , which is fixedly mounted on the top surface inside the anti-collision cover, and the bottom end of the first electric cylinder 30 is fixedly connected to the support frame 7 .

[0081] As an optional embodiment, the track is fixedly connected to the rear end of the body of the stacker 6, and the support frame 7 is slidably connected to the surface of the track.

[0082] Specifically, through the setting of the anti-collision beam 4, when the debris is lower than or close to the height of the chassis of the forklift 6, the height of the anti-collision beam 4 can be adjusted, and the bottom of the forklift 6 can be shielded and protected by the anti-collision beam 4, which is helpful to prevent the debris from entering under the chassis of the forklift 6.

[0083] As a further optimized embodiment, the anti-collision baffle 5 also includes

[0084] A fixing seat 8, the fixing seat 8 is fixedly installed at a position near the end of the bottom of the anti-collision member;

[0085] Two sliding seats 9 are slidably installed on the fixed seat 8 and the ends are rotatably connected to the anti-collision baffle 5 through connecting pieces, and the rotation angle of the sliding seat 9 and the anti-collision baffle 5 is limited by the ends of the sliding seat 9, and an elastic support member is arranged between the sliding seat 9 and the fixed seat 8.

[0086] As an optional embodiment, the elastic support member specifically includes a support rod 10, which is slidably inserted on the fixed seat 8, and the support rod 10 is telescopically inserted with the end of the sliding seat 9. The surface of the support rod 10 is sleeved with a first return spring 11, and the two ends of the first return spring 11 are fixedly connected to the sliding seat 9 and the fixed seat 8 respectively.

[0087] Specifically, when the anti-collision baffle 5 collides with the moving debris, the anti-collision baffle 5 and the sliding seat 9 as a whole will squeeze the elastic support component, and the elastic support component will undergo elastic deformation to buffer the impact force, thereby buffering the impact force received by the anti-collision baffle 5 and helping to reduce the damage caused by rigid collision.

[0088] As a further optimized embodiment, the connecting piece includes

[0089] A first installation cavity 12, which is opened at the end of the sliding seat 9, a connecting shaft 13 is fixedly connected in the first installation cavity 12, a rotating member 14 is rotatably connected to the surface of the connecting shaft 13, and the rotating member 14 is fixedly connected to the anti-collision baffle 5;

[0090] Angle maintaining assembly, the angle maintaining assembly includes an arc groove 15, a limit block 16 and a support spring 17. The arc groove 15 is opened on the rotating member 14, and the limit block 16 is fixedly connected to the surface of the connecting shaft 13. The limit block 16 is connected to the inner wall of the arc groove 15 through the support spring 17 to realize elastic support for the connection state of the rotating member 14 and the connecting shaft 13.

[0091] Specifically, when the anti-collision baffle 5 is not adjusted in angle, the relative position of the limit block 16 in the arc groove 15 is maintained by the support of the support spring 17, thereby maintaining the anti-collision baffle 5 as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Fig. 9 and Fig.10 The storage state can reduce the impact on the side space of the forklift 6 while providing protection, and in this state, the non-protective surface of the anti-collision baffle 5 can contact the end of the sliding seat 9 to form a support, reducing the dependence on the rotating member 14.

[0092] As a further optimized embodiment, the angle adjustment unit includes

[0093] A linkage block 18, the linkage block 18 is fixedly connected to the side of the rotating member 14;

[0094] A push plate 19, which is slidably inserted into the fixing seat 8 and contacts the linkage block 18;

[0095] The pushing power member is used to push the pushing plate 19 to push the linkage block 18 during the process of adjusting the angle of the anti-collision baffle 5, and then rotate the linkage block 18 and the rotating member 14 as a whole relative to the connecting shaft 13 to achieve the angle adjustment of the anti-collision baffle 5.

[0096] As an optional embodiment, Figure 4 and Fig.10 The driving power member specifically includes a second electric cylinder 20, the telescopic rod end of the second electric cylinder 20 is fixedly connected to the ends of the two driving plates 19 on the same side through a connecting plate. By setting the second electric cylinder 20, the movement of the driving plate 19 can be directly controlled, which is convenient and quick.

[0097] Specifically, when the debris is caught below the chassis of the stacker 6, the driving member moves the pushing plate 19, the pushing plate 19 will push the linkage block 18, the linkage block 18 and the rotating member 14 will rotate relative to the connecting shaft 13, and then synchronously drive the anti-collision baffle 5 to flip, forming a Fig.11 The state can be realized to block the moving debris, and the blocking angle of the anti-collision baffle 5 can limit the moving direction of the debris, so that the debris will turn away from the wheel during the continuous movement.

[0098] To further explain, the push plate 19 is slidably inserted into the sliding seat 9 at the same time. After the push plate 19 is pushed, the side of the push plate 19 is fitted with the side of the linkage block 18 to achieve limited support. When the anti-collision baffle 5 encounters a collision, the linkage block 18 will act on the side of the push plate 19 without causing a reaction force on the driving power part.

[0099] As a further optimized embodiment, the pushing unit includes

[0100] A second installation cavity 21, which is provided at the bottom end of the anti-collision member;

[0101] Two first pushers 22 are symmetrically rotatably connected in the second installation cavity 21 , and a first flip adjustment component is connected between the first pushers 22 and the inner wall of the second installation cavity 21 .

[0102] Specifically, when it is detected that the debris at the rear end of the forklift 6 is lower than or close to the height of the chassis of the forklift 6, the first pusher 22 is adjusted to flip through the first flip adjustment component to move the debris at the rear end of the forklift 6, drive the debris to a position away from the rear end of the forklift 6, and drive the debris to the oblique rear on both sides of the forklift 6, which is conducive to moving the debris away from the forklift 6 and providing a favorable space for the next step of movement.

[0103] As another optional embodiment, Figure 3 , Figure 8 and Fig. 9 As shown, the driving power member specifically includes a linkage frame 23 and a cam 26. The linkage frame 23 is slidably connected to the bottom surface of the anti-collision member, and is fixedly connected to the fixed seat 8 with a second return spring 24. Two first inclined grooves 25 are provided on the linkage frame 23, and a linkage rod 27 is slidably connected in the two first inclined grooves 25. A linkage plate 28 is fixedly connected to the surface of the linkage rod 27. The linkage plate 28 sequentially penetrates the linkage frame 23 and the anti-collision member and then extends to the second installation cavity 21. The cam 26 is fixedly connected to the rotating end of the first pushing member 22, and the convex surface of the cam 26 contacts the linkage plate 28.

[0104] It should be understood that during the flipping process of the first pusher 22, the first pusher 22 will drive the cam 26 to rotate, the distal end of the cam 26 will gradually push the linkage member, the linkage member will drive the linkage rod 27 to move in the first inclined slot 25, the linkage rod 27 and the first inclined slot 25 will cooperate to drive the linkage frame 23 towards the fixed seat 8, the linkage frame 23 will synchronously drive the push plate 19 to push and adjust the linkage block 18 until the angle of the anti-collision baffle 5 is adjusted;

[0105] It should be further explained that the advantage of the embodiment of the pushing power member relative to the setting of the second electric cylinder 20 is that there is no need to set up more power units, it can be achieved through linkage, and no electric control is required, it is adapted to the working state of the first pushing member 22, when the first pushing member 22 is stored, the anti-collision baffle 5 can be stored in time, and in the process of flipping and pushing the first pushing member 22, the anti-collision baffle 5 can be linked in time to be in a tilted protection state, and no separate control is required.

[0106] As a further optimized embodiment, Fig.11 As shown, the push unit also includes

[0107] The second pushing member 29 is rotatably connected to the surface of the first pushing member 22, and the pushing angle formed relative to the first pushing member 22 is adjusted by a second flip adjustment assembly arranged in the second mounting cavity 21, so as to further push the debris on the ground to a direction away from the body of the forklift 6.

[0108] As a further optimized embodiment, the first flip adjustment component is specifically a third electric cylinder 35 , and two ends of the third electric cylinder 35 are rotatably connected to the first pusher 22 and the inner wall of the second installation cavity 21 respectively.

[0109] It should be understood that, by providing the third electric cylinder 35 , the flipping state of the first pushing member 22 can be adjusted, thereby providing power for the flipping of the first pushing member 22 .

[0110] As a further optimized embodiment, the second flip adjustment component includes

[0111] A pushing track 31, which is fixedly connected to a side of the second pushing member 29 away from the pushing surface, and includes a second inclined groove 3101 and a straight groove 3102;

[0114] It should be understood that when the debris is caught below the chassis of the stacker 6 or close to the chassis of the stacker 6, in the process of pushing the debris obliquely to the rear by the first pusher 22, the sliding plate 32 will slide relative to the first pusher 22 under the limited pulling of the pulling rod 34, and the sliding plate 32 will simultaneously drive the linkage column 33 to move in the second inclined groove 3101, so as to push the second pusher 29. The second pusher 29 will flip over and push the debris pushed by the first pusher 22 further obliquely to the rear, thereby further adjusting the pushing angle. On the one hand, it is beneficial to push the debris away from the tail end of the stacker 6, and on the other hand, it prevents the first pusher 22 from further increasing its flipping angle and driving the debris to move to the side direction of the stacker 6.
