Technical Field

[0001] This application belongs to the field of grader technology, specifically relating to a blade assembly and a grader. Background Technology

[0002] In construction machinery, graders are commonly used for leveling, shaping, and smoothing ground. The grader's blade is the core component for achieving this leveling operation. The blade works in conjunction with the grader's movement to remove or collect materials such as sand and gravel, thereby achieving a level surface.

[0003] In related technologies, fixed baffles are installed at both ends of the shovel to prevent material collected by the shovel from overflowing from both ends. However, fixed baffles have poor flexibility. Furthermore, when the shovel needs to be cleaned, the obstruction by the baffles makes cleaning inconvenient. Utility Model Content

[0005] Therefore, the first aspect of this application provides a shovel assembly.

[0006] The second aspect of this application provides a grader.

[0007] In view of the above, according to a first aspect of the embodiments of this application, a shovel assembly is provided, comprising: a shovel body; a baffle movably disposed at the end of the shovel body; and a drive assembly disposed on the shovel body, including an angle adjustment shaft connected to the baffle; wherein the drive assembly is used to drive the baffle to rotate relative to the shovel body to block or open the end of the shovel body.

[0008] In one possible implementation, the drive assembly includes: a drive member disposed on the blade body; a first gear disposed on the drive end of the drive member; a second gear meshing with the first gear; and an angle adjustment shaft movably disposed on the blade body, one end of the angle adjustment shaft being connected to the second gear.

[0009] In one possible implementation, the drive assembly further includes: a linkage frame detachably connected to the baffle, wherein one end of the linkage frame away from the baffle is connected to the angle adjustment shaft.

[0010] In one possible implementation, the diameter of the second gear is larger than the diameter of the first gear.

[0011] In one possible implementation, the drive unit, the first gear, and the second gear are respectively located above the blade body.

[0012] In one possible implementation, the blade assembly further includes: a mounting plate disposed at the end of the blade body, including a mating groove, and the drive assembly disposed on the mounting plate; the baffle includes a mating edge corresponding to the mating groove; wherein, when the mating edge extends into the mating groove, the baffle blocks the end of the blade body.

[0013] In one possible implementation, the mounting plate includes: a mating portion connected to the end of the blade body, including the mating groove; and a mounting portion disposed at least above the mating portion, wherein the drive assembly is mounted on the mounting portion.

[0014] In one possible implementation, the blade body includes a first soil-facing surface; the baffle includes a second soil-facing surface, which is flush with the first soil-facing surface.

[0015] In one possible implementation, two baffles are provided, each movably disposed at one end of the blade body, and the two baffles are connected to the two drive components in a one-to-one correspondence.

[0016] According to a second aspect of the embodiments of this application, a grader is provided, including the blade assembly as described above.

[0017] The blade assembly and grader provided in this application can achieve at least the following technical effects:

[0018] In this application, the blade body can be used to collect materials. A baffle is movably disposed at the end of the blade body, meaning the baffle can move relative to the blade body to block or open the end of the blade body, improving the baffle's flexibility. The angle adjustment shaft of the drive assembly is connected to the baffle. Rotation of the angle adjustment shaft of the drive assembly drives the baffle to rotate relative to the blade body, realizing active control of the opening and closing of the baffle relative to the blade body, and enabling precise control of the baffle's opening and closing angle, improving the reliability of the baffle's opening and closing operation.

[0019] When the blade assembly is used on a grader, the baffle blocks the end of the blade body during material collection to prevent sand and gravel from spilling from both sides, thus improving work efficiency. When the blade body and / or baffle need cleaning, the baffle leaves the end of the blade body open for easy cleaning and greater flexibility in use.

[0038] Combination Figures 1 to 6 As shown, according to a first aspect of the embodiments of this application, a shovel assembly 100 is provided, including a shovel body 101, a baffle 102, and a drive assembly 103. The baffle 102 is movably disposed at the end of the shovel body 101. The drive assembly 103 is disposed on the shovel body 101, and the drive assembly 103 includes an angle adjustment shaft 104, which is connected to the baffle 102. The drive assembly 103 is used to drive the baffle 102 to rotate relative to the shovel body 101 to block or open the end of the shovel body 101.

[0039] In this embodiment, the blade body 101 can be used to collect materials. The specific structure of the blade body 101 is not limited, and it can be applied to a grader to collect materials.

[0040] In this embodiment, the baffle 102 is movably disposed at the end of the blade body 101. That is, the baffle 102 can move relative to the blade body 101 to block or open the end of the blade body 101, thereby improving the flexibility of the baffle 102. The shape of the baffle 102 is not limited and can be adapted to the shape of the end of the blade body 101 to block the end of the blade body 101.

[0041] In this embodiment, the angle adjustment shaft 104 of the drive component 103 is connected to the baffle 102. The rotation of the angle adjustment shaft 104 of the drive component 103 drives the baffle 102 to rotate relative to the blade body 101, thereby realizing active control of the opening and closing of the baffle 102 relative to the blade body 101 and accurately controlling the opening and closing angle of the baffle 102, thus improving the reliability of the opening and closing operation of the baffle 102.

[0042] When the blade assembly 100 is used on a grader, while the blade assembly 100 is collecting materials, the baffle 102 blocks the end of the blade body 101 to prevent materials such as sand and gravel from overflowing from both sides of the blade body 101, thus improving work efficiency. When the blade body 101 and / or the baffle 102 need to be cleaned, the baffle 102 leaves the end of the blade body 101 open for easy cleaning and more flexible use.

[0043] Combination Figures 1 to 6 As shown, in some embodiments, the drive assembly 103 includes a drive member 105, a first gear 106, a second gear 107, and an angle adjustment shaft 104. The drive member 105 is disposed on the blade body 101. The first gear 106 is disposed on the drive end of the drive member 105. The second gear 107 meshes with the first gear 106. The angle adjustment shaft 104 is movably disposed on the blade body 101, and one end of the angle adjustment shaft 104 is connected to the second gear 107.

[0044] In this embodiment, the driving component 105 is disposed on the blade body 101. Specifically, the driving component 105 can be disposed on the blade body 101 through a support structure. For example, the blade body 101 is connected to the mounting plate 109, the driving component 105 is fixedly mounted on the mounting plate 109, and the driving component 105 is located above the blade body 101.

[0045] In this embodiment, the first gear 106 is disposed at the driving end of the driving member 105. The driving member 105 rotates when it operates, causing the driving end of the driving member 105 to rotate, which in turn drives the first gear 106 to rotate. The second gear 107 meshes with the first gear 106, causing the first gear 106 to rotate and thus driving the second gear 107 to rotate. An angle adjustment shaft 104 is movably disposed on the blade body 101, with one end connected to the second gear 107, so that the rotation of the second gear 107 causes the angle adjustment shaft 104 to rotate relative to the blade body 101. The angle adjustment shaft 104 is fixedly connected to a baffle 102, so that the baffle 102 rotates relative to the blade body 101 via the angle adjustment shaft 104, thereby blocking or opening the end of the blade body 101. Angle adjustment shaft 104 is movably mounted on blade body 101. Specifically, the end of blade body 101 can be connected to mounting plate 109, and angle adjustment shaft 104 is movably mounted on mounting plate 109 so that angle adjustment shaft 104 is movably mounted on blade body 101.

[0046] In this embodiment, the specific type of the driving component 105 is not limited; for example, it can be a stepper motor. The driving end of the driving component 105 can be connected to the first gear 106 via the transmission shaft 117. The first gear 106, the second gear 107, and the angle adjustment shaft 104 constitute a gear transmission mechanism. The stepper motor drives the gear transmission mechanism to rotate the baffle 102 relative to the blade body 101, thereby realizing the active opening and closing of the baffle 102.

[0047] Combination Figures 1 to 6 As shown, in some embodiments, the drive assembly 103 further includes a linkage frame 108. The linkage frame 108 is detachably connected to the baffle 102, and one end of the linkage frame 108 away from the baffle 102 is connected to the angle adjustment shaft 104.

[0048] In this embodiment, the linkage frame 108 and the baffle 102 are detachably connected. For example, the linkage frame 108 and the baffle 102 can be detachably connected by reinforcing bolts, which facilitates disassembly and maintenance. The end of the linkage frame 108 away from the baffle 102 is connected to the angle adjustment shaft 104. Specifically, the end of the linkage frame 108 away from the baffle 102 is fixedly connected to the angle adjustment shaft 104, so that the rotation of the angle adjustment shaft 104 drives the linkage frame 108 to rotate, thereby driving the baffle 102 to rotate relative to the blade body 101.

[0049] In this embodiment, a multi-stage transmission system is formed by the first gear 106, the second gear 107, the linkage frame 108, and the angle adjustment shaft 104, and stepless adjustment is achieved in conjunction with the drive component 105. This allows the opening range of the baffle 102 relative to the blade body 101 to be adjustable to adapt to different working conditions, improve the applicability of the blade assembly 100, and thus enhance the adaptability of the grader.

[0050] In one possible implementation, the linkage 108 is L-shaped. One end of the linkage 108 is detachably connected to the baffle 102. The other end of the linkage 108 is fixedly connected to the angle adjustment shaft 104.

[0051] Combination Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, the diameter of the second gear 107 is larger than the diameter of the first gear 106.

[0052] In this embodiment, the diameter of the second gear 107 is larger than the diameter of the first gear 106. The first gear 106 is disposed at the driving end of the driving member 105. The second gear 107 meshes with the first gear 106. That is, the large-diameter second gear 107 is driven to rotate by the small-diameter first gear 106, thereby achieving speed reduction and torque increase, and improving the stability of the baffle 102 during the opening and closing process.

[0053] Combination Figure 1 As shown, in some embodiments, the drive unit 105, the first gear 106, and the second gear 107 are respectively located above the blade body 101.

[0054] In this embodiment, the drive component 105, the first gear 106, and the second gear 107 are integrated and installed on the top of the blade body 101 to minimize the interference of ground debris on the operation of the drive component 103 and improve work efficiency.

[0055] Combination Figure 1 and Figure 4 As shown, in some embodiments, the blade assembly 100 further includes a mounting plate 109. The mounting plate 109 is disposed at the end of the blade body 101 and includes a mating groove 110. A drive assembly 103 is disposed on the mounting plate 109. A baffle 102 includes a mating edge 111 corresponding to the mating groove 110. When the mating edge 111 extends into the mating groove 110, the baffle 102 blocks the end of the blade body 101.

[0056] In this embodiment, the mounting plate 109 is disposed at the end of the blade body 101. The drive assembly 103 and the baffle 102 are mounted on the mounting plate 109 to achieve a configuration on the blade body 101, thereby improving the structural integration. For example, combined with... Figure 1As shown, mounting plates 109 are connected to both the left and right ends of the blade body 101. Each mounting plate 109 is equipped with a drive assembly 103 and a baffle 102 to control the sealing and opening of the left and right ends of the blade body 101.

[0057] In this embodiment, the mounting plate 109 includes a fitting groove 110, and the baffle 102 includes a fitting edge 111 corresponding to the fitting groove 110. That is, the fitting edge 111 is in a position corresponding to the fitting groove 110, and the shape of the fitting edge 111 is adapted to the fitting groove 110.

[0058] In a specific application example, when the mating edge 111 extends into the mating groove 110, the baffle 102 blocks the end of the blade body 101. That is, the mating edge 111 extends into the mating groove 110, and the side of the baffle 102 is in contact with the end face of the blade body 101 to block the side of the blade body 101, improve the sealing effect, and prevent construction materials from leaking out from the side of the blade body 101 as much as possible, thereby improving work efficiency.

[0059] In another specific application example, when it is necessary to clean the blade body 101, the drive component 105 operates to rotate the drive end of the drive component 105. The drive end drives the first gear 106 to rotate, the first gear 106 drives the second gear 107 to rotate, and then drives the angle adjustment shaft 104 to rotate, so as to drive the linkage frame 108 to rotate a certain angle, so that the mating edge 111 of the baffle 102 moves out of the mating groove 110, and the baffle 102 opens the end of the blade body 101, so that the end of the blade body 101 is unobstructed, that is, the blade body 101 is fully exposed, which facilitates cleaning of the blade body 101, improves cleaning efficiency and convenience, and makes the operation flexible and reliable.

[0060] Combination Figures 1 to 4 As shown, in some embodiments, the mounting plate 109 includes a mating portion 112 and a mounting portion 113. The mating portion 112 is connected to the end of the blade body 101, and the mating portion 112 includes a mating groove 110. The mounting portion 113 is disposed at least above the mating portion 112. The drive assembly 103 is mounted on the mounting portion 113.

[0061] In this embodiment, the engaging portion 112 is connected to the end of the blade body 101. The shape of the engaging portion 112 is not limited, but it is adapted to the shape of the end of the blade body 101 so that the engaging portion 112 can be smoothly connected to the end of the blade body 101 and the baffle 102 can smoothly seal the end of the blade body 101. The engaging portion 112 includes an engaging groove 110, which engages with the engaging edge 111 of the baffle 102.

[0062] In this embodiment, combined with Figure 1As shown, the mounting portion 113 is at least disposed above the mating portion 112. Specifically, the mounting portion 113 can be connected to the top of the mating portion 112, or it can be connected to both the top and side of the mating portion 112. Because the mounting portion 113 is at least disposed above the mating portion 112, the upper end of the mounting plate 109 extends above the blade body 101, that is, the top of the mounting plate 109 is higher than the top of the blade body 101. The drive assembly 103 is mounted on the mounting portion 113, thereby enabling the installation of the drive assembly 103, and ensuring that at least a portion of the drive assembly 103 is located above the blade body 101.

[0063] Combination Figure 4 As shown, in one possible implementation, the mounting portion 113 of the mounting plate 109 is provided with a mounting opening 114. An angle adjustment shaft 104 is disposed on the mounting plate 109 and passes through the mounting opening 114. One end of the angle adjustment shaft 104 extends to the outside of the mounting plate 109 and is fixedly connected to the second gear 107. A linkage frame 108 is at least partially disposed within the mounting opening 114, and one end of the linkage frame 108 is fixedly connected to the angle adjustment shaft 104. The mounting opening 114 provides space for the swinging of the linkage frame 108. The driving member 105 and the first gear 106 can be respectively disposed on opposite sides of the mounting plate 109. The driving end of the driving member 105 is fixedly connected to the transmission shaft 117, which passes through the mounting plate 109 and is fixedly connected to the first gear 106, thereby engaging the first gear 106 with the second gear 107.

[0064] Combination Figure 1 As shown, in one possible implementation, the lower end of the mounting plate 109 is flush with the lower end of the blade body 101, which facilitates the grader to perform leveling operations on the ground.

[0065] Combination Figure 1 As shown, in some embodiments, the blade body 101 includes a first soil-facing surface 115. The baffle 102 includes a second soil-facing surface 116, which is flush with the first soil-facing surface 115.

[0066] In this embodiment, the first soil-facing surface 115 can be the foremost surface of the blade body 101 when it directly contacts the material. The second soil-facing surface 116 can be the foremost surface of the baffle 102 when it contacts the material. By making the second soil-facing surface 116 flush with the first soil-facing surface 115, the left and right ends of the blade body 101 are fitted with the baffle 102 to form a roughly closed end structure, thereby improving the efficiency of the blade assembly 100 in ground leveling operations. When cleaning is required, it is actively opened. Since the opening and closing of the baffle 102 is actively controlled by the drive assembly 103, the effectiveness of active opening operations is improved, and operating costs are reduced.

[0067] Combination Figure 1 and Figure 6As shown, in some embodiments, there are two baffles 102, which are movably disposed at both ends of the blade body 101, and the two baffles 102 are connected to the two drive components 103 in a one-to-one correspondence.

[0068] In this embodiment, two baffles 102 are movably disposed at the left and right ends of the blade body 101, respectively, and the two baffles 102 are connected to two drive components 103 in a one-to-one correspondence. That is, each drive component 103 is connected to the corresponding baffle 102 to drive the corresponding baffle 102 to rotate to block or open both ends of the blade body 101. By connecting the two baffles 102 to the two drive components 103 in a one-to-one correspondence, the rotation of each baffle 102 can be driven independently, thus improving the applicability.

[0069] Combination Figures 1 to 6 As shown, according to a second aspect of the embodiments of this application, a grader is provided, including the blade assembly 100 as described above.

[0070] In this embodiment, the grader includes the blade assembly 100 as described above, which can minimize the spillage of materials such as sand and gravel from both sides of the blade body 101 during material collection, thereby improving work efficiency. When cleaning is required, the baffle 102 opens the end of the blade body 101 for easy cleaning and more flexible use. Other technical effects of the blade assembly 100 are described in the foregoing embodiments of this application and will not be repeated here.

[0071] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application. The above are merely preferred embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the protection scope of this application.
