Cleaning equipment, attachments and machinery

Abstract

This invention relates to the field of work machinery, providing a cleaning device, attachment, and work machinery. The cleaning device includes: a movable base movably connected to the attachment; a striking member slidably engaged with the movable base and configured to slide towards or away from the attachment to strike it; and an actuating assembly connected to the striking member, configured to cause the striking member to slide along the movable base. When the movable base moves relative to the attachment, it drives the striking member to move relative to the attachment, thereby changing the striking position of the striking member on the attachment. This allows the striking member to strike and vibrate the attachment at different positions, resulting in a larger striking range and thus promoting the removal of more adhesive material from the attachment, improving the cleaning effect.

Description

Technical Field

[0001] This invention relates to the field of work machinery technology, and in particular to a cleaning device, attachments and work machinery. Background Technology

[0002] Construction machinery includes, but is not limited to, excavators and loaders, which typically perform various tasks using attachments such as buckets and bulldozer blades. However, when construction machinery encounters loose and damp materials such as soil, mud, sand, or coal during operation, the materials can easily stick to the attachments, forming adhesive residues that affect work efficiency.

[0003] To remove adhesive residue from attachments, related technologies provide a cleaning device including a motor, an impact head, and a return spring. The impact head is movably mounted, and the return spring drives the impact head to move closer to the attachment. The motor drives the impact head to retract via a push plate mounted on the motor shaft. When the push plate disengages from the impact head, the return spring drives the impact head to reset and impact the attachment, causing the attachment to vibrate. The adhesive residue on the attachment breaks off due to the vibration.

[0004] Although the cleaning devices in the aforementioned related technologies can remove the adhesive from the attachments to a certain extent, the fixed and singular tapping point of the cleaning device results in poor cleaning effect and low cleaning efficiency. Summary of the Invention

[0005] This invention provides a cleaning device, attachment, and working machinery to solve or improve the shortcomings of cleaning devices in related technologies, which have a fixed single tapping point, resulting in poor cleaning effect on adhesives, and to achieve the purpose of improving the cleaning effect of the cleaning device.

[0006] This invention provides a cleaning device for cleaning attachments, comprising:

[0007] A movable base for movably connecting to the attachment;

[0008] A striking element that slides with the movable base and is configured to slide in a direction toward or away from the attachment to strike the attachment;

[0009] An actuation component is connected to the striking element and is configured to allow the striking element to slide along the movable seat.

[0010] According to a cleaning device provided by the present invention, the actuation assembly includes an actuating member for connection with the attachment, the actuating member having a guide structure, and the striking member slidingly engaging with the guide structure;

[0011] Along the movable direction of the movable seat, the guide path of the guide structure is configured as a curve or broken line that undulates in the direction of approaching or away from the attachment, and the guide path of the guide structure has at least two low points.

[0012] According to a cleaning device provided by the present invention, the actuation assembly further includes a connecting rod, the connecting rod being connected to the striking member, and the striking member being slidably engaged with the guide structure via the connecting rod.

[0013] According to a cleaning device provided by the present invention, the connecting rod is rotatably connected to the striking member.

[0014] According to a cleaning device provided by the present invention, the number of movable seats is set to at least two, and each movable seat is provided with a corresponding striking element;

[0015] The striking element between two adjacent movable seats is connected so that the connected striking elements can move synchronously, or the two adjacent movable seats are connected so that the two adjacent movable seats can move synchronously.

[0016] According to a cleaning device provided by the present invention, the movable seat is provided with at least two of the aforementioned striking elements, and each of the striking elements on the movable seat is slidably engaged with the guide structure;

[0017] Accordingly, the striking element between two adjacent movable seats is connected, including:

[0018] At least one pair of the striking elements are connected between two adjacent movable seats.

[0019] A cleaning device according to the present invention further includes an elastic element and a guide element for connecting with the attachment;

[0020] The movable seat is slidably engaged with the guide member and can move along the guide member between a first position and a second position. The elastic member is connected to the movable seat and is configured to drive the movable seat to the first position or the second position.

[0021] According to a cleaning device provided by the present invention, a driving device is further included, which is connected to the movable base and is used to drive the movable base to move.

[0022] The present invention also provides an attachment, wherein the attachment is equipped with the cleaning device described above.

[0023] The present invention also provides a working machine, including the cleaning device as described above or the attachment as described above.

[0024] The cleaning device provided by the present invention allows the striking member to slide in a sliding engagement with the movable seat, and allows the striking member to slide in a direction close to or away from the attachment. When the actuating component causes the striking member to slide along the movable seat, the striking member can strike the attachment, causing the attachment to vibrate, thereby causing the adhesive to fall off.

[0025] By movably connecting the movable base to the attachment and slidingly engaging the striking element with the movable base, the movable base can drive the striking element to move relative to the attachment when it moves relative to the attachment. This changes the striking position of the striking element on the attachment, allowing it to strike and vibrate the attachment at different positions. The striking range of the striking element is larger, which in turn promotes the removal of more adhesive on the attachment, improving the cleaning effect of the attachment.

[0026] In addition, cleaning devices in related technologies fix the tapping point of the attachment to a single location, meaning that the same spot is tapped every time, which can easily damage the attachment after repeated tapping. The cleaning device provided by this invention, however, moves the movable base relative to the attachment, allowing the tapping component to tap the attachment at more locations. Therefore, compared to cleaning devices in related technologies, under the same number of taps, the cleaning device provided by this invention can reduce the number of taps received at a single location, thereby reducing the probability of damage from repeated tapping and increasing the service life of the attachment.

[0027] The attachments and working machinery provided by the present invention, since they include the cleaning device provided by the present invention, also include all the advantages of the cleaning device described above. Attached Figure Description

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0038] The cleaning device provided in the related technology drives the impact head to retract through a push plate set on the motor shaft. When the push plate is separated from the impact head, the return spring drives the impact head to reset and impact the attachment, causing the attachment to vibrate. The adhesive on the attachment is broken and falls off after being vibrated. Although it can remove the adhesive on the attachment to a certain extent, the impact point of this cleaning device is fixed and single, resulting in poor cleaning effect and low cleaning efficiency.

[0039] In order to solve or improve the shortcomings of cleaning devices in related technologies, which have a fixed single tapping point and thus poor cleaning effect on adhesives, and to achieve the purpose of improving the cleaning effect of the cleaning device, this invention provides a cleaning device, attachments and working machinery.

[0040] The following is combined with Figures 1 to 6 The cleaning apparatus provided in the embodiments of the present invention is described.

[0041] Specifically, the cleaning device is used to clean attachment 1, that is, the cleaning device is installed on attachment 1. Optionally, attachment 1 includes, but is not limited to, a bulldozer blade and a bucket.

[0042] The cleaning device includes a movable base 2, a striking element 3, and an actuating component 4.

[0043] The movable base 2 is movably connected to the attachment 1. Specifically, the movable base 2 is configured to move on the surface of the attachment 1 to be struck. Optionally, for a bucket, the surface to be struck is either the sides or the back of the bucket. For a bulldozer blade, the surface to be struck is the back of the bulldozer blade. Optionally, the movable base 2 and the attachment 1 are slidably engaged, allowing the movable base 2 to slide on the surface of the attachment 1.

[0044] The striking element 3 is slidably engaged with the movable base 2, and the striking element 3 is configured to slide in a direction approaching or moving away from the attachment 1 to strike the attachment 1. Specifically, the striking element 3 is configured to slide in a direction approaching or moving away from the surface to be struck of the attachment 1 to strike the surface to be struck of the attachment 1. Optionally, the striking element 3 can be a striking block, and the striking element 3 can be a columnar structure, a block structure, or a rod structure.

[0045] The actuating component 4 is connected to the striking element 3, and the actuating component 4 is configured to enable the striking element 3 to slide along the movable seat 2.

[0046] The cleaning device provided in this embodiment of the invention allows the striking member 3 to slide in a sliding engagement with the movable seat 2, and allows the striking member 3 to slide in a direction close to or away from the attachment 1. When the actuating component 4 causes the striking member 3 to slide along the movable seat 2, the striking member 3 can strike the attachment 1, causing the attachment 1 to vibrate, thereby causing the adhesive to fall off.

[0047] By movably connecting the movable seat 2 to the attachment 1 and slidingly engaging the striking element 3 with the movable seat 2, the movable seat 2 can drive the striking element 3 to move relative to the surface to be struck when it moves on the surface to be struck, thereby changing the striking position of the striking element 3 on the surface to be struck. This allows the striking element 3 to strike and vibrate the attachment 1 at different positions, resulting in a larger striking range. This, in turn, can cause more adhesive to fall off the attachment 1, improving the cleaning effect on the attachment 1.

[0048] In addition, the cleaning devices in related technologies have a fixed tapping point on the attachment 1, meaning that the same position is tapped every time it is cleaned, which can easily lead to damage to the attachment 1 after repeated tapping. However, the cleaning device provided in this embodiment of the invention moves the movable seat 2 relative to the attachment 1, allowing the tapping member 3 to tap the attachment 1 at more locations. Therefore, compared to the cleaning devices in related technologies, under the same number of taps, the cleaning device provided in this embodiment of the invention can reduce the number of taps received at a single tapping location, thereby reducing the probability of the attachment 1 being damaged by repeated tapping and increasing the service life of the attachment 1.

[0049] refer to Figure 3 As shown, in some embodiments provided by the present invention, the movable base 2 is provided with a guide hole for the striking element 3 to extend into, and the striking block slides in cooperation with the guide hole.

[0050] In this embodiment, the striking element 3 slides with the guide hole on the movable base 2, making the connection structure between the movable base 2 and the striking element 3 simple and easy to manufacture.

[0051] refer to Figure 3 As shown, in some embodiments provided by the present invention, the guide hole is configured as a through hole, and the striking member 3 is configured to pass through the through hole and directly abut against the attachment 1.

[0052] In this embodiment, by setting the guide hole as a through hole, the striking member 3 can directly contact and impact the attachment 1, thereby generating a stronger striking vibration on the attachment 1, so as to improve the cleaning effect on the attachment 1.

[0053] To protect attachment 1, in some embodiments of the present invention, the striking element 3 is made of a material with a hardness lower than that of attachment 1. For example, attachment 1 is typically made of steel, while the striking element 3 can be made of copper, aluminum, or engineering plastic. Thus, because the hardness of the striking element 3 is lower than that of attachment 1, more damage occurs on the striking element 3, thereby reducing the probability of attachment 1 being damaged.

[0054] Of course, to save on the cost of the striking part 3, it is not limited to making the entire striking part 3 a softer material. For example, a detachable impact head 301 can be provided at the end of the striking part 3 that contacts the attachment 1, and the hardness of the material of the impact head 301 is less than that of the material of the attachment 1. For example, the material of the impact head 301 can be copper, aluminum, or engineering plastic.

[0055] Optionally, the impact head 301 can be detachably connected by a threaded fastener connection, so that the impact head 301 can be replaced if it is damaged.

[0056] Of course, the impact head 301 is not limited to the rigid structures such as metal or engineering plastics mentioned above. For example, in some embodiments provided by the present invention, the impact head 301 is set as a flexible pad. The hardness of the flexible pad is less than that of the attachment 1. The flexible pad can form a buffering and shock-absorbing effect between the striking member 3 and the attachment 1, reducing the problem of the attachment 1 being damaged by the impact of the striking member 3 for a long time.

[0057] Alternatively, the flexible pad may be a plush pad, a felt pad, or a rubber pad.

[0058] Alternatively, the flexible pad can be detachably connected by adhesive or threaded fasteners.

[0059] In some embodiments provided by the present invention, the guide hole is set as a blind hole, that is, the end of the guide hole near the attachment 1 is closed.

[0060] In this embodiment, as the striking member 3 moves along the movable seat 2, it strikes the bottom of the guide hole, generating vibration. The vibration is transmitted to the attachment 1 through the movable seat 2, thereby causing the attachment 1 to vibrate and causing the adhesive to fall off.

[0061] With this configuration, the striking element 3 strikes the movable seat 2, and the movable seat 2 transmits the vibration to the attachment 1. This reduces the impact of the striking element 3 on the attachment 1, thereby reducing the problem of the attachment 1 being damaged by repeated strikes.

[0062] Furthermore, in order to improve the effect of the movable seat 2 transmitting vibration to the attachment 1, the movable seat 2 is in contact with the surface of the attachment 1 to be struck.

[0063] In some embodiments provided by the present invention, the cleaning device further includes a drive device 7.

[0064] The drive unit 7 is connected to the movable base 2 and is used to drive the movable base 2 to move.

[0065] In this embodiment, the moving seat 2 is driven by the driving device 7, eliminating the need for manual operation of the moving seat 2, thereby improving the automation level of the cleaning device and reducing the intensity of manual labor.

[0066] Optionally, the drive device 7 includes a rotation drive assembly 701, a connector 702, and a drive rod 703. The rotation drive assembly 701 is connected to the attachment 1, i.e., the rotation drive assembly 701 is mounted on the attachment 1. The connector 702 is connected to the output shaft of the rotation drive assembly 701 and rotates with the output shaft of the rotation drive assembly 701. One end of the drive rod 703 is rotatably connected to the connector 702, and the connection point between the drive rod 703 and the connector 702 is offset from the rotation center of the connector 702. The other end of the drive rod 703 is rotatably connected to the movable seat 2. For example, both ends of the drive rod 703 are hinged to the connector 702 and the movable seat 2, respectively.

[0067] In this embodiment, the connector 702, the drive rod 703, and the movable seat 2 form a crank-slider mechanism. When the rotation drive assembly 701 rotates, the movable seat 2 is driven to reciprocate through the connector 702 and the drive rod 703.

[0068] Optionally, the rotation drive assembly 701 includes a hydraulic motor. This configuration allows the hydraulic motor to be powered by the hydraulic system of the working machinery, eliminating the need for a separate drive unit and thus simplifying the structure of the cleaning device.

[0069] Of course, the rotation drive assembly 701 is not limited to including a hydraulic motor; for example, the rotation drive assembly 701 may also include an electric motor. For example, in the case of electric work machinery, the electric motor can obtain electrical energy from the power battery of the electric work machinery.

[0070] Of course, the drive device 7 is not limited to the form of the rotation drive assembly 701 described above. For example, in other embodiments provided by the present invention, the drive device 7 is mounted on the attachment 1, and the drive device 7 includes a cylinder, a hydraulic cylinder, a rack and pinion drive mechanism, or a screw and nut drive mechanism. For example, one end of the cylinder or hydraulic cylinder is connected to the attachment 1, and the other end is connected to the movable seat 2. For example, the rack and pinion drive mechanism is mounted on the attachment 1 and connected to the movable seat 2 through a gear pair to drive the movable seat 2 to move. For example, the screw and nut drive mechanism is mounted on the attachment 1 and connected to the movable seat 2 through a screw pair to drive the movable seat 2 to move.

[0071] In some embodiments of the present invention, the actuation component 4 includes a cylinder or a hydraulic cylinder, with one end of the cylinder or hydraulic cylinder connected to the movable seat 2 and the other end connected to the striking element 3. The reciprocating extension and retraction of the cylinder or hydraulic cylinder drives the striking element 3 to slide along the movable seat 2.

[0072] Of course, the actuation component 4 is not limited to the aforementioned cylinder or hydraulic cylinder. For example, in other embodiments provided by the present invention, the actuation component 4 includes a rack and pinion drive mechanism or a lead screw and nut drive mechanism, which is disposed on the movable seat 2 and connected to the striking block. The reciprocating motion of the rack and pinion drive mechanism or the lead screw and nut drive mechanism drives the striking block to slide along the movable seat 2.

[0073] Of course, the actuation component 4 is not limited to the gear and rack drive mechanism or the lead screw and nut drive mechanism described above. For example, refer to Figure 3 and Figure 5 As shown, in other embodiments provided by the present invention, the actuation assembly 4 includes an actuating member 401 connected to the attachment 1. The actuating member 401 is provided with a guide structure 402, and the striking member 3 is slidably engaged with the guide structure 402.

[0074] Along the movable direction of the movable seat 2, the guide path of the guide structure 402 is set as a curve or a broken line, and the curve or the broken line oscillates in the direction of approaching or moving away from the attachment 1. (Reference) Figure 3 As shown, the guide path of the guide structure 402 has at least two low points a. Here, low point a refers to a low point or valley point generated when the guide path oscillates towards the attachment 1. Figure 3 For example, the movable direction of the movable seat 2 is the vertical direction in the figure. Correspondingly, the guide path of the guide structure 402 is set as a curve or broken line extending along the vertical direction.

[0075] In this embodiment, during the movement of the movable seat 2, the striking member 3 moves with the movable seat 2. Since the striking member 3 slides with the guide structure 402, the striking member 3 oscillates along the guide path of the guide structure 402. When the striking member 3 oscillates along the guide path to the low point a, the striking member 3 can strike the attachment 1 to make the attachment 1 vibrate.

[0076] With this configuration, by moving the movable base 2, the striking element 3 can strike the attachment 1 under the guidance of the guide structure 402, thus eliminating the need for a separate power drive unit for the striking element 3. This simplifies the structure of the cleaning device and reduces its cost. For example, the power provided by the drive device 7 can both move the movable base 2 to change the striking position of the striking element 3 and move the striking element 3 along the guide structure 402 to strike the attachment 1.

[0077] In addition, by making the guide path include at least two low points a, the moving seat 2 can strike the attachment 1 at least twice in a single trip during its movement, thereby improving the cleaning effect on the attachment 1.

[0078] Optionally, the guide path of the guide structure 402 can be set as a sine curve or a sine broken line.

[0079] In some embodiments provided by the present invention, the actuation assembly 4 further includes a connecting rod 403. The connecting rod 403 is connected to the striking member 3, and the striking member 3 is slidably engaged with the guide structure 402 via the connecting rod 403. Optionally, the guide structure 402 is configured as a guide groove, one end of the connecting rod 403 is connected to the striking member 3, and the other end of the connecting rod 403 extends into the guide groove and is slidably engaged with the guide groove.

[0080] In this embodiment, the striking element 3 is slidably engaged with the guide structure 402 of the actuator 401 via a connecting rod 403. The connecting rod 403 can form a transition between the striking element 3 and the actuator 401, thereby allowing for more flexible positioning of the actuator 401. For example, Figure 5 As shown, the actuator 401 is disposed on one side of the movable seat 2, that is, the actuator 401 and the movable seat 2 are arranged in parallel.

[0081] Optionally, the connecting rod 403 is rotatably connected to the striking member 3. For example, the striking member 3 is provided with a mounting hole, and the connecting rod 403 extends into the mounting hole and rotatably engages with the mounting hole.

[0082] With this configuration, when the connecting rod 403 slides along the guide structure 402, the connecting rod 403 can rotate, thereby reducing the sliding friction between the connecting rod 403 and the guide structure 402, thus reducing the wear between the connecting rod 403 and the guide structure 402 and improving the service life of the cleaning device.

[0083] In some embodiments provided by the present invention, the number of movable seats 2 is set to at least two, and each movable seat 2 is provided with a corresponding striking element 3.

[0084] In this embodiment, by providing at least two movable seats 2, the tapping position of the cleaning device on the attachment 1 can be increased, thereby making the tapping range of the cleaning device on the attachment 1 wider, and thus improving the cleaning effect and cleaning efficiency of the cleaning device on the attachment 1.

[0085] refer to Figure 1 As shown, in some embodiments provided by the present invention, the striking element 3 between two adjacent movable seats 2 is connected so that the connected striking element 3 can move synchronously.

[0086] In this embodiment, by connecting the striking element 3 between two adjacent movable seats 2, when any one movable seat 2 moves, the movable seat 2 can drive the adjacent movable seats 2 to move through the striking element 3. Thus, by driving one movable seat 2, all movable seats 2 can move synchronously, increasing the striking range of the cleaning device without increasing the number of driving devices 7, simplifying the structure of the cleaning device and reducing its cost.

[0087] like Figure 1 and Figure 4 As shown, optionally, with the striking element 3 between two adjacent movable seats 2 connected, for a cleaning device that uses an actuator 401 to drive the striking element 3, the striking element 3 between adjacent movable seats 2 can be connected by a connecting rod 403. That is, the striking element 3 between two adjacent movable seats 2 is connected to the connecting rod 403, and the connecting rod 403 is slidably engaged with the guide structure 402.

[0088] In some embodiments provided by the present invention, the movable seat 2 is provided with at least two striking elements 3, and each striking element 3 on the movable seat 2 is slidably engaged with the guide structure 402.

[0089] Accordingly, the striking element 3 between two adjacent movable seats 2 is connected, including:

[0090] At least one pair of striking elements 3 are connected between two adjacent movable seats 2.

[0091] In this embodiment, during the movement of each movable seat 2, at least two striking elements 3 oscillate along the guide path of the guide structure 402. When the striking element 3 oscillates along the guide path to a low point, the striking element 3 can strike the attachment 1 to make the attachment 1 vibrate.

[0092] By increasing the number of striking parts 3 on the movable seat 2, the number of times the cleaning device strikes the attachment 1 when the movable seat 2 moves a unit length can be increased. This allows the cleaning device to strike the attachment 1 more times while keeping the moving path length of the movable seat 2 constant, thereby improving the cleaning effect and efficiency of the attachment 1.

[0093] Specifically, the striking parts 3 between two adjacent movable seats 2 are connected one-to-one by corresponding connecting rods 403.

[0094] Of course, the striking element 3 between two adjacent movable seats 2 is not limited to a one-to-one correspondence; for example, as... Figure 4 As shown, each movable seat 2 is equipped with a corresponding actuator 401. A pair of striking elements 3 between two adjacent movable seats 2 are connected by a connecting rod 403, while the remaining striking elements 3 between two adjacent movable seats 2 are slidably engaged with the corresponding actuator 401 via the corresponding connecting rod 403. This arrangement reduces the number of long connecting rods 403, lowers the weight of the cleaning device, and simplifies the structure of the cleaning device.

[0095] Of course, it is not limited to connecting the striking element 3 between two adjacent movable seats 2. For example, in other embodiments provided by the present invention, two adjacent movable seats 2 are connected so that the two adjacent movable seats 2 can move synchronously.

[0096] In this embodiment, by connecting two adjacent movable seats 2, when any one movable seat 2 moves, the movable seat 2 can drive the adjacent movable seats 2 to move. Thus, by driving one movable seat 2, all movable seats 2 can move synchronously, increasing the tapping range of the cleaning device. Furthermore, it eliminates the need to increase the number of driving devices 7, thereby simplifying the structure of the cleaning device and reducing its cost.

[0097] Specifically, assuming two adjacent movable seats 2 are connected, for a cleaning device that uses an actuator 401 to drive the striking element 3, each movable seat 2 is provided with a corresponding actuator 401, and the striking element 3 on each movable seat 2 is slidably engaged with the corresponding actuator 401. For example, the striking element 3 on each movable seat 2 is slidably engaged with the corresponding actuator 401 via a connecting rod 403. Furthermore, each movable seat is provided with at least two striking elements 3.

[0098] In some embodiments provided by the present invention, the cleaning device further includes an elastic element 5 and a guide element 6 connected to the attachment 1.

[0099] The movable seat 2 is slidably engaged with the guide member 6 and can move along the guide member 6 between a first position and a second position. The elastic member 5 is connected to the movable seat 2 and is configured to drive the movable seat 2 to the first position or the second position.

[0100] In this embodiment, after the attachment 1 is cleaned by the cleaning device, the elastic element 5 drives the movable seat 2 to move to the first position or the second position, which can reduce the problem of the movable seat 2 moving during the movement of the attachment 1, causing the striking element 3 to collide with the attachment 1 and produce abnormal noise or damage.

[0101] Optionally, the guide member 6 is configured as a guide rod, with both ends of the guide rod connected to the attachment 1 via supports 8. The movable seat 2 is provided with a guide seat 201, which slides with the guide rod. Optionally, two guide seats 201 are provided, each sliding with one of the two guide rods.

[0102] Optionally, the elastic element 5 is configured as a spring, which is fitted around the outer periphery of the guide rod, with one end of the spring connected to the support 8 and the other end connected to the guide seat 201. The spring can drive the guide seat 201 to abut against another support 8.

[0103] This invention also provides an attachment 1.

[0104] Specifically, accessory 1 is equipped with the cleaning device described above.

[0105] It should be noted that accessory 1 is equipped with a cleaning device, and thus possesses all the advantages of the cleaning device mentioned above, which will not be elaborated here.

[0106] refer to Figures 4-6 As shown, optionally, the attachment 1 is a bulldozer blade, which includes a blade body 103, a first support 101, and a second support 102. There are two first supports 101, which are arranged side by side on the back of the blade body 103, and the second support 102 is connected between the two first supports 101.

[0107] The movable base 2 is movably disposed on the back of the shovel body 103. For example, the movable base 2 is slidably connected to the back of the shovel body 103 via the guide member 6. The actuator 401 is mounted on the back of the shovel body 103. The rotation drive assembly 701 is disposed on the second bracket 102.

[0108] Furthermore, the guide 6 and the actuator 401 are detachably connected to the shovel body 103, and the rotation drive assembly 701 is detachably connected to the second bracket 102, so that the cleaning device can be detachably connected to the attachment 1.

[0109] Of course, attachment 1 can also be set as the bucket of an excavator or a loader, with the cleaning device set on the side wall or back of the bucket.
