Description

[0001] JOYSTICK-MOUNTED ROTARY SEATS OF CONSTRUCTION MACHINE WITH ANTI-DUST

[0002] INGRESS CONFIGURATION

[0003] TECHNICAL AREA

[0004] The invention relates generally to a configuration for preventing dust ingress in joystick-mounted rotary seats of construction machines.

[0005] The invention relates in particular to a configuration for preventing the ingress of dust into the opening for the installation in the cabin of the hoses and cables of the joysticks connected to the seat or seat bracket and controlling the construction machine, especially in construction machines with rotary seats.

[0006] KNOWN STATE OF THE ART

[0007] In construction machines, joysticks are used to control the construction machine by positioning them on the seat or on the cabin floor. The positioning of the joysticks on the seat is frequently preferred because it provides ergonomics for the operator to use the construction machine, especially when using the backhoe and loader functions. For this reason, especially the use of joysticks on the rotary seat is frequently preferred by construction machine manufacturers. Rotary seats used in construction machines have the ability to rotate min 180 degrees. In this way, the operator can easily use the loader functions in front of the machine and the backhoe functions behind the machine.

[0008] In rotary seats with joysticks, joystick hoses and electrical cables enter under the machine cabin and are connected to the joysticks through the seat bracket. The opening for the hoses and cables to enter the cabin causes dust to enter the cabin. In the current state of the art, rotary seats with joysticks use hydraulic rotary dispersing mechanisms to prevent dust ingress. Rotary dispersing mechanisms prevent dust ingress but are very costly.

[0009] Another existing technique is the use of rubber hose and electrical cable separators at the joystick to prevent dust ingress in rotary seats with joysticks. Rubber hose and electrical cable separators are less costly than rotary dispensing mechanisms, but the rotary nature of the seat prevents the movement of hoses and electrical cables. In addition, although the part cost of rubber hose and electrical cable separators is low, the assembly difficulty and assembly times are high.

[0010] In another existing technique, slits are cut in the rubber separators to prevent dust ingress in rotary seats with joysticks. However, although these slits allow the movement of the hoses, they cause installation difficulties and prevent dust entry to a limited extent.

[0011] A search of the state of the art led to the disclosure of application CN213228381U. The application discloses a miniature excavator of the crawler type comprising an excavator main part and an isolation cover. It is stated that the isolation cover plays the role of isolation and dust prevention for the electric telescopic column in the excavator. However, there is no mention of the rubber circular and rectangular assemblies with slots for hydraulic hoses and electrical cables for ease of installation.

[0012] As a result, configurations are being developed to prevent dust ingress, so new configurations are needed that will eliminate the disadvantages mentioned above and provide solutions to existing systems.

[0013] PURPOSE OF THE INVENTION

[0014] The present invention relates to an anti-dust ingress configuration which fulfills the above-mentioned requirements, eliminates all disadvantages and brings some additional advantages. The main purpose of the invention is to prevent the ingress of dust into the opening opened for the installation of the hoses and cables of the joysticks, which are connected on the seat or seat bracket and control the construction machine, into the cabin in construction machines with rotary seats.

[0015] One object of the invention is to provide easy, labor-free assembly of joysticks and to reduce assembly costs.

Therefore, the evaluation should be made by taking these figures and the detailed description into consideration.

[0043] DETAILED DESCRIPTION OF THE INVENTION

[0044] In this detailed description, the preferred configurations of the inventive anti-dust ingress configuration are described only for the purpose of a better understanding of the subject matter and without limitation.

[0045] The invention, a representative view of which is shown in Figure 1, is a dust entry preventing configuration positioned between the seat bracket (15) at the bottom of the seat assembly (11) and the cabin floor (12) of the construction machine in order to prevent dust entry into the opening where the hoses (15) and electrical connections of the joysticks (15) that provide the control of the construction machines with rotary seats are mounted inside the construction machine cabin.

[0046] The configuration shown in Figure 2 in cross-sectional view (A) comprises an annular anti-dust assembly (1) for attachment to the seat bracket (15) having a circular shape, comprising: • A rubber part (2) damping vibrations to the seat assembly (11),

[0047] • Brush bristles (4) on the rubber part (2), which wrap around the hoses (15) and electrical connections to the joysticks coming from under the cabin floor (12) and preventing dust and air from entering the mounting opening under the seat assembly (11), and a brush holder (3) holding the brush bristles (4) together,

[0048] • A mounting slot (5) for assembly and disassembly of hoses (15) and electrical connections without dismantling.

[0049] In an alternative configuration of the invention, the quadrangular assembly (6) can be used instead of the anti-dust assembly (1) as shown in Figure 3 for the quadrangular form seat bracket (15). As can be seen in the B-B section (B) shown in Figure 4, said quadrangular assembly (6) comprises the following:

[0050] • A quadrangular rubber piece (7) damping vibrations to the seat assembly (11),

[0051] • Quadrangular brush bristles (9) on the rubber part (7), which wrap around the hoses (15) and electrical connections from under the cabin floor (12) to the joysticks, preventing dust and air from entering the mounting opening under the seat assembly (11), and a quadrangular brush holder (8) holding the quadrangular brush bristles (9) together,

[0052] • A quadrangular mounting slot (10) for assembly and disassembly of hoses (15) and electrical connections without dismantling.

[0053] In alternative configurations of the invention, the density of the bristles (4) can be increased or decreased according to the size of the opening under the seat assembly (11). Thus, by using different brush lengths and thicknesses for different seat and / or cabin models, suitable solutions can be developed that do not require additional mold investment.

[0054] In the preferred configurations of the invention, plastic brush bristles (4) and rubber parts (2), which are used in various places, are combined by co-injection method. In addition to the co-injection production method, bolted or bolted connections with metal, wood, etc. materials can also be used.
