Description

Technical Field

[0001] This disclosure relates to the technical field of bulldozing engineering, and more specifically, to a bulldozing apparatus. Background Technology

[0002] Complex and varied terrain and working conditions place stringent demands on the adaptability of bulldozers. Traditional bulldozer blades are mostly fixed, making it difficult to meet different operational needs and resulting in poor operational flexibility. To change different driving postures, bulldozers need to have a tilting function, capable of tilting the bulldozer backward, with the tilting mechanism being a key component. Currently, traditional tilting mechanisms consist of a tilting frame, lifting cylinder, tilting cylinder, and limit device, etc., with many hinge points, resulting in poor structural rigidity and stability, easily leading to component deformation under stress. Furthermore, when the bulldozer tilts onto the roof of the driving vehicle, the overall height of the driving vehicle is relatively large, affecting the driving vehicle's passability. Summary of the Invention

[0003] To address at least one of the technical problems in the prior art, embodiments of this disclosure provide a bulldozing device capable of maintaining the movement trajectory of two blades within a plane defined by the direction of travel and the width direction.

[0004] This disclosure provides a bulldozing device disposed at the front of a driving vehicle. The bulldozing device includes: a jacking frame; a first driving assembly disposed at the center of the front of the jacking frame; a linkage assembly configured to reciprocate linearly along the travel direction of the driving vehicle under the drive of the first driving assembly; two blades, one end of each blade rotatably connected to both sides of the linkage assembly in the width direction of the driving vehicle and extending in opposite directions along the width direction; and two sliding assemblies mounted on the front of the jacking frame and slidingly engaging with the back surfaces of the two blades, so that while the first driving assembly drives the linkage assembly to move along the travel direction and change the angle between the two blades, the movement trajectory of the two blades is maintained within a plane defined by the travel direction and the width direction.

[0005] According to some embodiments of this disclosure, the linkage component includes: a support connected to the output end of the first drive component, the support extending along both sides of the drive vehicle in the height direction to form a mounting portion; a pin penetrating through the two mounting portions and extending along the height direction, one end of the two blades being rotatably mounted on the pin.

[0006] According to some embodiments of the present disclosure, each of the above-mentioned blades has two spaced-apart mounting rings at one end, the two mounting rings are sleeved on the outside of the pin, and one of the mounting rings is located between the two mounting portions, and the other mounting ring is located on the outside of the two mounting portions.

[0007] According to some embodiments of this disclosure, the pusher frame includes: a support portion adapted to support the first drive assembly; and two support arms formed by the support portion extending away from and away from the two blades along the width direction on both sides, the front sides of the two support arms being adapted to support the two sliding assemblies respectively.

[0008] According to some embodiments of this disclosure, each of the aforementioned blades has a groove on its back side along the aforementioned width direction, and each of the aforementioned sliding components includes: a support frame, mounted on the front side of one of the aforementioned support arms; and a slider, rotatably mounted on the aforementioned support frame and slidingly engaged with the aforementioned groove, so that while the aforementioned first driving component drives the aforementioned support to reciprocate linearly along the aforementioned travel direction, the other end of the aforementioned blade is brought closer to or away from the aforementioned support arm by slidingly engaging with the aforementioned groove.

[0009] According to some embodiments of this disclosure, the aforementioned pusher frame further includes two connecting arms, each formed by extending from one end of the two aforementioned support arms away from the aforementioned support portion along the aforementioned travel direction.

[0010] According to some embodiments of this disclosure, the bulldozing device further includes: two rotating rods, the first ends of the two rotating rods being rotatably connected to the rear sides of the two connecting arms opposite to the front side along the travel direction, and the first ends of the two rotating rods being hinged to the two sides of the vehicle body of the driving vehicle in the width direction via the rear sides of the two connecting arms.

[0011] According to some embodiments of this disclosure, each of the aforementioned rotating rods includes: two side plates disposed facing each other along the aforementioned width direction at the second end of the rotating rod opposite to the aforementioned first end.

[0012] According to some embodiments of this disclosure, the bulldozing device further includes: two second drive components, respectively installed on both sides of the vehicle body in the width direction, and the output end of each of the second drive components is rotatably connected between the two side plates to drive the second end of the rotating rod to rotate around the first end.

[0013] According to some embodiments of this disclosure, the bulldozing device further includes: two third drive components, respectively installed on the front side of the two connecting arms, with the output end of each third drive component rotatably connected between the two side plates, so that while the second drive component drives the second end of the rotating rod to rotate, it drives the connecting arm to rotate around the first end of the rotating rod, so that the two blades switch between a working state located on the front side of the vehicle body and a standby state located above the vehicle body under the drive of the pusher frame.

[0014] According to an embodiment of the bulldozing device disclosed herein, the bulldozing device is disposed at the front of a driving vehicle. The bulldozing device includes a pusher frame, a first drive assembly, a linkage assembly, two blades, and two sliding assemblies. The first drive assembly drives the linkage assembly to reciprocate linearly along the travel direction, causing one end of each of the two blades to move forward or backward synchronously. By rotatably connecting one end of each of the two blades to the two sides of the linkage assembly located in the width direction of the driving vehicle, the two blades are allowed to rotate around the hinge point with the linkage assembly, keeping the movement trajectory of the two blades within a plane defined by the travel direction and the width direction. By mounting the two sliding assemblies at the front of the pusher frame and slidingly engaging with the back sides of the two blades respectively, the angle between the two blades and the overall posture can be changed by adjusting the fore-and-aft position of the linkage assembly along the travel direction. This allows the device to adapt to different bulldozing operation requirements under complex and varied terrain and working conditions, improving the operational flexibility of the bulldozing device.

[0062] Figure 1 This is a perspective view of a bulldozing apparatus according to an illustrative embodiment of the present disclosure.

[0063] A bulldozing device is provided according to an embodiment of this disclosure, the bulldozing device being disposed at the front side of a driving vehicle. For example... Figure 1 As shown, the bulldozing device includes a jacking frame 1, a first drive assembly 2, two blades 4, and two sliding assemblies 5. The first drive assembly 2 is located at the center of the front side of the jacking frame 1. The linkage assembly 3 is configured to move along the direction of travel of the driving vehicle (e.g., under the drive of the first drive assembly 2) Figure 1 The two blades 4 move in a reciprocating linear motion (as shown in the X direction). One end of each blade 4 is rotatably connected to the linkage assembly 3 in the width direction of the driving vehicle (e.g., in the X direction). Figure 1 On both sides of the Y direction shown, and extending in opposite directions along the width direction. Two sliding components 5 are mounted on the front side of the pusher frame 1 and slide in cooperation with the back of the two blades 4 respectively, so as to keep the movement trajectory of the two blades 4 within the plane defined by the travel direction and the width direction while the first drive component 2 drives the linkage component 3 to move along the travel direction and change the angle between the two blades 4.

[0064] In this implementation, the first drive assembly 2 drives the linkage assembly 3 to reciprocate linearly along the travel direction, causing one end of each of the two blades 4 to move forward or backward synchronously. By rotatably connecting one end of each of the two blades 4 to the two sides of the linkage assembly 3 located in the width direction of the driving vehicle, the two blades 4 are allowed to rotate around the hinge point with the linkage assembly 3, keeping the movement trajectory of the two blades 4 within the plane defined by the travel direction and the width direction. By installing two sliding assemblies 5 on the front side of the pusher frame 1 and slidingly engaging with the back of each of the two blades 4, the included angle and overall posture between the two blades 4 can be changed by adjusting the front and rear position of the linkage assembly 3 along the travel direction. For example, the angle between the two blades 4 can be adjusted within the range of 90° to 270° to adapt to the functional requirements of material collection, flat pushing, or spreading in different terrains and bulldozing operation modes, thereby improving the terrain adaptability and operational flexibility of the bulldozing device.

[0065] Figure 2 yes Figure 1 A magnified view of a portion of point A in the middle. Figure 3 This is a side view of a bulldozing apparatus according to an illustrative embodiment of the present disclosure. Figure 4 This is a partial perspective view of a linkage assembly according to an illustrative embodiment of the present disclosure, showing two mounting bases, supports, two mounting parts, and a baffle.

[0066] According to embodiments of this disclosure, such as Figure 2 , Figure 3 and Figure 4 As shown, the linkage component 3 includes a support 31 and a pin 32. The support 31 is connected to the output end of the first drive component 2, and the support 31 extends along the height direction of the driving vehicle (e.g., ...). Figure 1 Mounting portions 311 are formed on both sides of the Z-direction shown in the diagram, extending along the travel direction. The pin 32 is penetrated by the two mounting portions 311 and extends along the height direction, with one end of each of the two blades 4 rotatably mounted on the pin 32.

[0067] In some illustrative embodiments, the support 31 extends along the travel direction toward the side closer to the first drive component 2 to form two mounting seats 33, and the output end of the first drive component 2 is mounted between the two mounting seats 33, so that the support 31 can reciprocate linearly along the travel direction under the drive of the first drive component 2.

[0068] In this implementation, the linear driving force generated by the first drive assembly 2 is directly transmitted to the support 31 through two mounting bases 33 connected to the output end of the first drive assembly 2, thereby driving the entire linkage assembly 3 and the two blades 4 mounted thereon to move synchronously along the travel direction. Two mounting portions 311 extending along the travel direction provide support for the pin 32 at two points along the height direction, forming a stable cantilever support structure to withstand the load from the two blades 4 during bulldozing operations. The pin 32 extending along the height direction provides a common axis of rotation for the two blades 4, allowing them to rotate freely around this axis. Furthermore, the independent rotational freedom of each blade 4 around the pin 32, combined with the constraint of each sliding component 5 on the back of each blade 4, allows each blade 4 to both translate and change its tilt angle when the linkage assembly 3 reciprocates linearly along the travel direction under the drive of the first drive assembly 2. This alters the included angle and overall posture between the two blades 4, providing a necessary basis for adjusting the blade state to adapt to different bulldozing conditions.

[0069] Figure 5 This is a first-view perspective view of a shovel according to an illustrative embodiment of the present disclosure. Figure 6 This is a second-view perspective view of a shovel according to an illustrative embodiment of the present disclosure.

[0070] According to embodiments of this disclosure, such as Figure 5 and Figure 6 As shown, each blade 4 has two spaced-apart mounting rings 42 at one end, as... Figure 2 As shown, two mounting rings 42 are sleeved on the outside of the pin 32, with one mounting ring 42 located between the two mounting parts 311 and the other mounting ring 42 located on the outside of the two mounting parts 311.

[0071] like Figure 2 and Figure 4 As shown, the two mounting rings 42 of the blade 4 located on the left side of the pin 32 are both sleeved on the outside of the pin 32. One mounting ring 42 is sleeved on the lower end of the pin 32 and is located between the two mounting parts 311. The other mounting ring 42 is sleeved on the upper end of the pin 32 and is located above the two mounting parts 311.

[0072] Similarly, the two mounting rings 42 of the blade 4 located on the right side of the pin 32 are both fitted onto the outside of the pin 32. One mounting ring 42 is fitted onto the lower end of the pin 32 and is located between the two mounting parts 311. The other mounting ring 42 is fitted onto the upper end of the pin 32 and is located above the two mounting parts 311. Furthermore, the position of the blade 4 located on the left side of the pin 32 on the pin 32 is higher than the position of the blade 4 located on the right side of the pin 32 on the pin 32.

[0073] To allow the two blades 4 to rotate freely around the common axis of rotation of the pin 32, a fixing member located at the upper end of the pin 32 and a mounting portion 311 located on the upper side of the support 31 jointly restrict the upper mounting ring 42 of the left blade 4 and the upper mounting ring 42 of the right blade 4 from being fitted onto the upper end of the pin 32. A fixing member located in the middle of the pin 32 and a mounting portion 311 located on the lower side of the support 31 jointly restrict the lower mounting ring 42 of the left blade 4 and the lower mounting ring 42 of the right blade 4 from being fitted onto the lower end of the pin 32.

[0074] In this embodiment, two spaced-apart mounting rings 42 are fitted onto the outside of the pin 32, forming two independent support points along the axial direction of the pin 32 for one end of each blade 4. By placing one mounting ring 42 between the two mounting portions 311 and the other mounting ring 42 outside the two mounting portions 311, the pin 32 passes through both mounting portions 311 while simultaneously forming a rotational engagement with the blade 4 at the two mounting rings 42. This arrangement ensures that the rotation axis of the blade 4 is constrained axially by both mounting portions 311 and the two mounting rings 42, increasing the contact area and support span at the connection. This two-point support and axial positioning enhances the blade 4's resistance to lateral loads and torsional stiffness when rotating around the pin 32, reducing swaying or deflection of the blade 4 due to uneven force during bulldozing operations. Furthermore, it ensures that the movement trajectory of the blade 4 is stable and controllable when rotating around the pin 32 to adjust its angle.

[0075] Figure 7 This is a perspective view of a pusher frame according to an illustrative embodiment of the present disclosure.

[0076] According to embodiments of this disclosure, such as Figure 7 As shown, the pusher frame includes a support portion 11 and two support arms 12. The support portion 11 is adapted to support the first drive assembly 2. The two support arms 12 are formed by extending from both sides of the support portion 11 in the width direction away from and away from the two blades 4, and the front sides of the two support arms 12 are adapted to support the two sliding assemblies 5 respectively.

[0077] In this implementation, the support portion 11 provides an installation interface for the first drive assembly 2, ensuring that the driving force of the first drive assembly 2 is effectively transmitted to the linkage assembly 3 along the travel direction, avoiding additional torque caused by installation offset. Support arms 12, extending from both sides of the support portion 11 in the width direction away from and away from the two blades 4, form a roughly bow-shaped structure. The two support arms 12 provide cantilever support for the two sliding assemblies 5, thus forming a stable frame composed of the support portion 11, the two support arms 12, and the sliding assemblies 5 mounted on the two support arms 12. This frame effectively transmits the driving force applied by the first drive assembly 2 and the soil reaction force borne by the two blades 4 during bulldozing to the vehicle body. The rigid extension of the two support arms 12 ensures that the two sliding assemblies 5 have a fixed position in the width direction, providing a precise and stable guiding reference surface for the sliding engagement of the back of the two blades 4. This ensures that the movement trajectory of the two blades 4 during movement is always constrained within a plane defined by the travel direction and the width direction, enhancing the structural stability and movement controllability of the bulldozing device.

[0078] Figure 8 This is a perspective view of a slider according to an illustrative embodiment of the present disclosure.

[0079] According to embodiments of this disclosure, such as Figure 2 , Figure 5 and Figure 8 As shown, each blade 4 has a groove 41 on its back along the width direction. Each sliding assembly 5 includes a support frame 51 and a slider 52. The support frame 51 is mounted on the front side of a support arm 12. The slider 52 is rotatably mounted on the support frame 51 and slides in engagement with the groove 41, so that while the first drive assembly 2 drives the support 31 to reciprocate linearly along the travel direction, the other end of the blade 4 moves closer to or away from the support arm 12 by sliding in engagement with the groove 41.

[0080] In some illustrative embodiments, each slider 52 includes a sliding plate 521 and two mounting plates 522. The two mounting plates 522 are arranged at intervals along the height direction on the side of the sliding plate 521 facing the support arm 12, and are rotatably mounted to the support frame 51 via a pivot or bearing. The sliding plate 521, through sliding engagement with the groove 41, causes the other end of the blade 4 to move closer to or further away from the support arm 12 while the first drive assembly 2 drives the support 31 to reciprocate linearly along the travel direction.

[0081] In this embodiment, the two mounting plates 522 are rotatably mounted on the support frame 51, reducing stress concentration. The sliding plate 521 slides in conjunction with the groove 41, allowing the slider 52 to slide relative to the blade 4 in the width direction. When the first drive assembly 2 drives the linkage assembly 3 and one end of the two blades 4 to move in the travel direction, the rotational motion of each blade 4 around the pin 32 is converted into sliding of the groove 41 on the back of the blade 4 relative to the slider 52. This motion coupling causes the contact point between the back of the blade 4 and the slider 52 to move along the groove 41, thereby guiding the other end of each blade 4 not connected to the pin 32 to generate an arc trajectory motion around the axis of the pin 32. This allows the other end of each blade 4 to swing closer to or away from the corresponding support arm 12, thus changing the tilt angle of the blade 4.

[0082] Figure 9 This is a side view of a bulldozing apparatus according to another illustrative embodiment of the present disclosure. Figure 10 yes Figure 9 A magnified view of a section at point B in the middle.

[0083] In some illustrative embodiments, such as Figure 9 and Figure 10 As shown, when the first drive assembly 2 drives the support 31 away from the support part 11 along the travel direction, the other ends of the two blades 4 approach the two support arms 12 under the drive of the two sliders 52, so that the included angle formed by the two blades 4 is less than 180°, presenting as shown in the figure. Figure 9 The V-shaped shovel shown.

[0084] In some illustrative embodiments, such as Figure 4 and Figure 10 As shown, the mounting portion 311 located on the lower side of the support 31 extends along the height direction to form a baffle 34 with a generally fan-shaped curved surface, so as to fill the opening formed when one end of the two blades 4 rotates around the pin 32 when the two blades 4 present a V-shaped blade.

[0085] In this implementation, the curved surface of the baffle 34 can conform to the movement trajectory of the back of the two blades 4, thereby filling the triangular or wedge-shaped opening formed between the two blades 4 due to rotation and separation. Thus, in the bulldozing operation mode of the V-shaped blades 4, the two blades 4 can prevent material from leaking backward from the opening between the two blades 4 along the direction of travel, reducing material loss and improving the collection efficiency of the bulldozing operation.

[0086] Furthermore, the height of the fan-shaped curved surface of the baffle 34 is lower than the height of the raised lower edges of the two blades 4 near the ground, so that when the two blades 4 are in a V-shaped shoveling state to a straight shoveling state (the two blades 4 are on the same straight line, such as...) Figure 3During the transition process (as shown), the lower edges of the two blades 4 can smoothly pass over the top of the curved surface of the baffle 34 without mechanical interference when rotating, ensuring that the movement of the two blades 4 is unimpeded when switching between different working states, and maintaining the smoothness and functional integrity of the bulldozer device in adjusting the blade posture.

[0087] Figure 11 This is a side view of a bulldozing apparatus according to another illustrative embodiment of the present disclosure.

[0088] In some illustrative embodiments, such as Figure 11 As shown, when the first drive assembly 2 drives the support 31 to move closer to the support 11 along the travel direction, the other ends of the two blades 4 are moved away from the two support arms 12 by the two sliders 52, so that the included angle formed by the two blades 4 is greater than 180°, presenting the shape of... Figure 11 The inverted V-shaped shovel shown.

[0089] According to embodiments of this disclosure, such as Figure 7 As shown, the pusher frame 1 also includes two connecting arms 13. The two connecting arms 13 are formed by extending one end of the two support arms 12 away from the support portion 11 along the travel direction.

[0090] In this implementation, by extending two connecting arms 13 from the ends of the two support arms 12 away from the support portion 11 along the direction of travel, the connection length between the jacking frame 1 and the vehicle body of the driving vehicle is increased. This makes the overall center of gravity and force distribution of the bulldozing device closer to the front axle of the driving vehicle, optimizing the load transfer path. Furthermore, the two connecting arms 13 enhance the structural continuity of the jacking frame 1 in the direction of travel, improving the overall rigidity and stability of the bulldozing device when subjected to longitudinal impacts and lateral loads generated during bulldozing operations, ensuring that the two blades 4 maintain a good working posture under complex working conditions.

[0091] Figure 12 This is a side view of a bulldozing device located at the front of the body of a driving vehicle, according to an illustrative embodiment of the present disclosure.

[0092] According to embodiments of this disclosure, such as Figure 12 As shown, the bulldozing device also includes two rotating rods 6. The first ends of the two rotating rods 6 are rotatably connected to the rear sides of the two connecting arms 13 opposite to the front side along the direction of travel, and the first ends of the two rotating rods 6 are hinged to the two sides of the vehicle body 9 in the width direction of the driving vehicle through the rear sides of the two connecting arms 13.

[0093] In this embodiment, the first ends of the two rotating rods 6 are hinged to the rear sides of the two connecting arms 13 on both sides of the vehicle body 9 in the width direction, respectively, so that the pusher frame 1 and the vehicle body 9 form a rotatable connection. The first end of each rotating rod 6 and the rear side of each connecting arm 13 share a hinge position on one side of the vehicle body 9 in the width direction, which can improve the rigidity and stability of the connection and reduce the risk of deformation under stress. Through this hinged connection, the pusher frame 1 is allowed to pitch around the two hinge points on both sides of the vehicle body 9 in the width direction.

[0094] Figure 13 This is a perspective view of a rotating rod according to an illustrative embodiment of the present disclosure.

[0095] According to embodiments of this disclosure, such as Figure 13 As shown, each rotating rod 6 includes two side plates 61. The two side plates 61 are disposed facing each other along the width direction at the second end of the rotating rod 6 opposite to the first end.

[0096] Figure 14 This is a side view of a bulldozing device located above the body of a driving vehicle, according to an illustrative embodiment of the present disclosure. Figure 15 This is a partial side view of a bulldozing device located above the body of a driving vehicle according to an illustrative embodiment of the present disclosure.

[0097] According to embodiments of this disclosure, such as Figure 14 and Figure 15 As shown, the bulldozing device also includes two second drive assemblies 7. The two second drive assemblies 7 are respectively installed on both sides of the vehicle body 9 in the width direction, and the output end of each second drive assembly 7 is rotatably connected between the two side plates 61 to drive the second end of the rotating rod 6 to rotate around the first end.

[0098] In some illustrative embodiments, such as Figure 1 , Figure 13 , Figure 14 and Figure 15 As shown, each of the two side plates 61 has a first mounting hole 63 facing each other. The output end of each second drive component 7 is rotatably hinged between the two side plates 61 through the two first mounting holes 63 to drive the second end of the rotating rod 6 to rotate around the first end.

[0099] In this implementation, the linear reciprocating motion of the second drive assembly 7 is converted into the rotational motion of the second end of the rotating rod 6 about the first end by hinged to the output end of each second drive assembly 7 and the two first mounting holes 63 of the two side plates 61. When the output end of the second drive assembly 7 extends or retracts, a pushing or pulling force is applied to the second end of the rotating rod 6, driving the second end of the rotating rod 6 to rotate about the first end, thereby changing the angle between the rotating rod 6 and the second drive assembly 7, realizing the adjustment of the pitch angle of the jacking frame 1, and improving the terrain adaptability of the bulldozing device.

[0100] According to embodiments of this disclosure, such as Figure 1 , Figure 13 , Figure 14 and Figure 15 As shown, the bulldozing device also includes two third drive assemblies 8. The two third drive assemblies 8 are respectively installed on the front side of the two connecting arms 13. The output end of each third drive assembly 8 is rotatably connected between the two side plates 61, so that while the second drive assembly 7 drives the second end of the rotating rod 6 to rotate, it drives the connecting arm 13 to rotate around the first end of the rotating rod 6, so that the two blades 4 switch between a working state located on the front side of the vehicle body 9 and a standby state located above the vehicle body 9 under the drive of the pusher frame 1.

[0101] In some illustrative embodiments, two side plates 61 are respectively provided with facing second mounting holes 62, and the output end of each third drive component 8 is rotatably connected between the two side plates 61 through the two second mounting holes 62, so as to drive the connecting arm 13 to rotate around the first end of the rotating rod 6 while the second drive component 7 drives the second end of the rotating rod 6 to rotate.

[0102] In this embodiment, the output end of each third drive assembly 8 is hinged to the two second mounting holes 62 of the two side plates 61, so that when the third drive assembly 8 extends or retracts, it can apply a pushing or pulling force to the second end of the rotating rod 6. This force creates a torque on the rotating rod 6 with the first end of the rotating rod 6 as the fulcrum, thereby driving the connecting arm 13 to rotate upward or downward about the fulcrum. When the third drive assembly 8 extends, it pushes the second end of the rotating rod 6 to cause the connecting arm 13 to rotate downward, driving the two blades 4 to descend to the working state at the front of the vehicle body 9 (e.g., ...). Figure 12 As shown in the diagram, at this point, the two shovels 4 can perform bulldozing operations.

[0103] When the third drive assembly 8 retracts, pulling the second end of the rotating rod 6 causes the connecting arm 13 to rotate upward, raising the two blades 4 to a standby state above the vehicle body 9 (e.g., Figure 14(As shown). Through the cooperation of the second drive assembly 7 and the third drive assembly 8, the two blades 4 can be retracted to the top of the vehicle body 9 during long-distance travel (such as ground travel or water travel) before the driving vehicle reaches the bulldozing position, keeping them in standby mode to reduce travel resistance and protect the two blades 4. At the same time, after the driving vehicle reaches the bulldozing position, the two blades 4 can be driven to descend to the front of the vehicle body 9 to maintain working mode, realizing flexible switching between standby mode and working mode.

[0104] According to embodiments of this disclosure, such as Figure 1 , Figure 7 , Figure 14 and Figure 15 As shown, the top of the rear side of the two connecting arms 13 are provided with grooves 131, which accommodate the rotating rods 6 when the two scrapers 4 are in a standby state above the vehicle body 9 under the drive of the pusher frame 1, thereby reducing the overall height of the driving vehicle and improving the driving vehicle's passability.
