Description
Technical Field
[0001] This invention relates to a scrubber rotation mounting structure and an excavator, belonging to the technical field of excavator scrubber mounting structure design. Background Technology
[0002] The windshield washer is an important component of the excavator's wiper system. Washers are typically installed behind the cab or inside the air filter compartment for the operator to periodically refill the windshield washer fluid. However, with the variety of excavators available today, their complex structures, compact spaces, and sometimes relatively tall bodies may not provide a suitable location for the washer. An inadequate design can cause inconvenience for the operator when refilling the washer fluid.
[0003] If installed inside the air filter chamber, it is usually mounted on a turntable at the bottom of the chamber. This area often houses electrical components such as batteries and wires, as well as the air filter itself. Adding windshield washer fluid is difficult due to the limited space, and leakage poses a safety hazard. Furthermore, the air filter chamber door must be opened to add the washer fluid. If installed externally, the washer's wiring and filler cap are made of plastic, which is susceptible to corrosion from prolonged exposure. Additionally, for tall excavators, the operator needs to climb onto the excavator and reach the top of the shed to add the washer fluid, which is time-consuming and laborious. Summary of the Invention
[0004] To address the shortcomings of existing technologies, the present invention aims to provide a washer rotation mounting structure and excavator, which solves the problem of inconvenience in adding windshield washer fluid in existing technologies.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A scrubber rotating mounting structure includes an air filter cover, an upper rotating handle, a locking nut, a rotating assembly, a scrubber, and a clamp;
[0007] The air filter cover is provided with a rotating hole, a first positioning hole and a second positioning hole, and the distances from the first positioning hole and the second positioning hole to the rotating hole are equal;
[0008] The upper rotating handle includes a limiting end, a handle, and an assembly end. The limiting end and the assembly end are respectively connected to both ends of the handle, and the assembly end is provided with an external thread.
[0009] The rotating assembly includes a connector, a rotating rod, and a mounting bracket. The connector has an internal thread, and the lower end of the connector is connected to the rotating rod. The mounting bracket is connected to the rotating rod and rotates with the rotating rod.
[0010] The assembly end is set in the rotating hole, and the lower end of the assembly end is connected to the connector by a lock nut. The washer is connected to the mounting bracket by a clamp.
[0011] When windshield washer fluid is not needed, the limiting end is located in the first positioning hole, and the washer is located inside the air filter cover at this position.
[0012] When windshield washer fluid needs to be added, the limiting end is located inside the second positioning hole, at which point the washer is located outside the air filter cover.
[0013] Furthermore, the rotating rod includes a bending rod, a lower rotating handle, and a connecting rod;
[0014] The connecting rod and the downward rotating handle are respectively connected to both ends of the bending rod. The connecting rod is fixed to the lower end of the connector, and the mounting bracket is fixed to the connecting rod.
[0015] Furthermore, the device also includes a limiting seat and a column, with the limiting seat fixed to the column;
[0016] The limiting seat includes an upper support plate, a lower support plate, and a back plate, with the upper and lower support plates connected in parallel at both ends of the back plate;
[0017] The upper support plate has an opening, and the connecting rod is set in the opening. The travel distance of the bending rod between the upper support plate and the lower support plate is L1, and the distance of the limiting end inserted into the first positioning hole or the second positioning hole is L2, where L1>L2.
[0018] When the rotating rod rotates to the point where the back of the mounting bracket contacts the column, the limiting end is coaxial with the first positioning hole.
[0019] When the rotating rod rotates to the point where the bending rod contacts the back plate, the limiting end is coaxial with the second positioning hole.
[0020] Furthermore, the mounting bracket includes a circular bend on its side, which is connected to the rotating rod.
[0021] Furthermore, the lower end of the mounting bracket is provided with a bending plate.
[0022] Furthermore, the mounting bracket is provided with threaded holes, and the clamp secures the washer in the threaded holes through a combination of bolts and washers.
[0023] Furthermore, the port of the limiting end is hemispherical.
[0024] Furthermore, the handle is semi-circular.
[0025] Furthermore, the bottom end of the connecting rod is provided with a through hole, a limiting pin is provided in the through hole, and a limiting washer is also provided in the connecting rod, with the limiting washer located between the limiting pin and the upper support plate.
[0026] An excavator comprising the washer rotation mounting structure of any of the preceding claims.
[0027] The beneficial effects achieved by this invention are as follows:
[0028] The washer's rotating installation structure designed in this invention allows the washer to be placed in the designated space when not in use, preventing it from being exposed to sunlight and rain, and from long-term corrosion and failure. When the customer needs to add windshield washer fluid, the washer can be placed outside the designated space through the rotating structure, providing ample operating space for the user to easily add the windshield washer fluid. After adding the fluid, the washer can be reset.
[0029] The structure also features a dual handle that moves synchronously, allowing for more options in the installation location of the washer. For example, it can be decided whether to install it inside or outside the air filter chamber. This way, users do not need to open the air filter chamber door or climb onto an excavator when adding windshield washer fluid, improving the structural layout efficiency for designers.

Detailed Implementation
[0034] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments and specific features in the embodiments are detailed descriptions of the technical solution of the present application, rather than limitations thereof. In the absence of conflict, the embodiments and technical features in the embodiments can be combined with each other.
[0035] Example 1
[0036] This embodiment discloses a rotating mounting structure for a washer, such as... Figure 1As shown, it includes an air filter cover 1, an upper rotating handle 2, a locking nut 3, a rotating assembly 4, a limit seat 5, a limit washer 6, a limit pin 7, a column 8, a washer 9, a clamp 10, and a bolt and washer assembly 11.
[0037] Figure 2 As shown, the air filter cover plate 1 is provided with a rotating hole 1-2, a first positioning hole 1-1, and a second positioning hole 1-3. The distances from the first positioning hole 1-1, the second positioning hole 1-3 to the rotating hole 1-2 are equal.
[0038] Figure 2 As shown, the upper rotating handle 2 includes a limiting end 2-1, a handle 2-2, and an assembly end 2-3. The limiting end 2-1 and the assembly end 2-3 are respectively connected to both ends of the handle 2-2, and the limiting end 2-1 and the assembly end 2-3 are arranged in the same direction. The port of the limiting end 2-1 is designed as a hemispherical shape to facilitate insertion into the first positioning hole 1-1 and the second positioning hole 1-3. The handle 2-2 is designed as a semi-circle to provide operating space for the operator to use. The assembly end 2-3 is designed with external threads to facilitate assembly with the connecting piece 4-1 of the rotating component 4.
[0039] Figure 2 As shown, the locking nut 3 is set on the external thread of the assembly end 2-3 and locked and fixed with the connector 4-1. It is used to lock the upper rotating handle 2 after it is assembled onto the rotating assembly 4, so as to prevent the upper rotating handle 2 from loosening from the connector 4-1 when the user rotates.
[0040] Figure 2 As shown, the rotating assembly 4 includes a connector 4-1, a rotating rod 4-2, and a mounting bracket 4-3. The connector 4-1 has an internal thread for mounting the upper rotating handle 2. The lower end of the connector 4-1 is connected to the rotating rod 4-2. The mounting bracket 4-3 has a circular bend 4-3.1 for welding with the rotating rod 4-2 to ensure the strength of the mounting bracket 4-3. The rotating rod 4-2 has a bend 4-2.2 for tangential contact with the lower support plate 5-2 and to support the rotating mounting structure 12; a lower rotating handle 4-2.3 for user operation; and a connecting rod 4-2.4 for fixing the mounting bracket 4-3. The connecting rod 4-2.4 and the lower rotating handle 4-2.3 are respectively connected to the two ends of the bend 4-2.2. The bottom end of the connecting rod 4-2.4 has a through hole 4-2.1 for assembling the limiting pin 7. Mounting bracket 4-3 includes mounting base 4-3.2 and bending plate 4-3.3. The bending plate 4-3.3 is connected to the bottom end of mounting base 4-3.2 and is used to support the washer 9. The mounting base 4-3.2 is provided with threaded holes for mounting clamp 10.
[0041] Figure 2As shown, the limiting seat 5 is welded to the column 8 (according to the actual layout, the limiting seat 5 can be welded to any fixing part). The limiting seat 5 includes an upper support plate 5-1, a lower support plate 5-2 and a back plate 5-3. The upper support plate 5-1 and the lower support plate 5-2 are connected in parallel at both ends of the back plate 5-3. The upper support plate 5-1 is provided with an opening and the lower support plate 5-2 are used to ensure the rotation of the rotating rod 4-2 and limit the vertical movement. In addition, the lower support plate 5-2 can also ensure the stability of the entire rotating structure after assembly.
[0042] The limiting pin 7 is located in the through hole 4-2.1, and the limiting pad 6 is located inside the connecting rod 4-2.4 and above the limiting pin 7. The limiting pin 7 is used to restrict the vertical downward movement of the limiting pad 6.
[0043] The distance that the rotating rod 4-2 moves upward is L1 (that is, the distance between the limiting pad 6 and the upper support plate 5-1).
[0044] The clamp 10 and the bolt washer assembly 11 work together to assemble the washer 9 onto the mounting bracket 4-3, with the lower end of the washer 9 abutting against the mounting bracket 4-3.
[0045] During installation, firstly, the rotating component 4 is assembled onto the limiting seat 5 through the through hole. Then, the limiting washer 6 and the limiting pin 7 are sequentially installed onto the rotating rod 4-2. Next, the upper rotating handle 2 is passed through the rotating hole 1-2, and the locking nut 3 is installed at a suitable position above the assembly end 2-3. Then, the upper rotating handle 2 is installed onto the connector 4-1 through the assembly end 2-3. Then, the locking nut 3 is tightened. Then, the upper rotating handle 2 is inserted into the first positioning hole 1-1 through the limiting end 2-1. Finally, the washer 9 is installed onto the mounting bracket 4-3 through the clamp 10 and the bolt washer assembly 11.
[0046] When not in use, the rotating mounting structure is in the following state: the back of the mounting bracket 4-3 is in contact with the column 8, and the limiting end 2-1 of the rotating handle 2 is inserted into the first positioning hole 1-1. At this time, the washer 9 is placed inside the air filter cover.
[0047] When users need to add windshield washer fluid, they can choose between turning the handle downwards (4-2.3) and turning the handle upwards (2). The following describes the different scenarios:
[0048] When the machine is low enough that windshield washer fluid can be added from the ground without needing to climb onto the excavator, the downward rotary handle 4-2.3 can be operated. The specific method is as follows: First, lift the downward rotary handle 4-2.3 upwards. When the handle is lifted a distance of L1, the vertical upward movement of the entire structure is restricted. Figure 1As shown, the distance L2 from the insertion of the limiting end 2-1 into the air filter cover 1 is less than the upward movement distance L1 of the rotating rod 4-2. This ensures that after the limiting end 2-1 of the upper rotating handle 2 is lifted from the first positioning hole 1-1, it does not interfere with the upper surface of the air filter cover 1 during rotation. Then, rotate the upper rotating handle 2 counterclockwise until the bending rod 4-2.2 contacts the back plate 5-3 of the limiting seat 5. At this time, the limiting end 2-1 is directly above the second positioning hole 1-3. Then, release the lower rotating handle 4-2.3, and the limiting end 2-1 is inserted into the second positioning hole 1-3. At this time, the washer is placed outside the air filter cover (e.g., Figure 3 As shown, users can easily add windshield washer fluid. After adding fluid, simply reverse the above steps to return the lower rotating handle 4-2.3 to its original position.
[0049] When the machine is too tall and requires climbing onto the excavator to add windshield washer fluid, the upper rotary handle 2 can be operated. The specific method is as follows: First, lift the limiting end 2-1 of the upper rotary handle 2 from the first positioning hole 1-1 and beyond the upper surface of the air filter cover 1. The distance L2 from which the limiting end 2-1 is inserted into the air filter cover 1 is less than the upward movement distance L1 of the rotary rod 4-2. This ensures that the limiting end 2-1 of the upper rotary handle 2 does not interfere with the upper surface of the air filter cover 1 during rotation after being lifted from the first positioning hole 1-1. Then, rotate the limiting end 2-1 of the upper rotary handle 2 above the second positioning hole 1-3 and insert it there. At this point, the washer is positioned outside the air filter cover (e.g., Figure 3 As shown, users can easily add windshield washer fluid. After adding the fluid, simply reverse the above steps to return the upper rotating handle 2 to its original position.
[0050] When selecting a design space, as mentioned above, designers only need to focus on designing the rotating hole 1-2, the first positioning hole 1-1, the second positioning hole 1-3, and the limiting seat 5 in appropriate locations. Other structures can be appropriately adjusted or borrowed from the structures provided in this article.
