[0001] The present application relates to the technical field of vehicle cleaning, and in particular to a rear axle cleaning device. Background technology:

[0002] The cleanliness of the rear axle box of a bulldozer has always been one of the important issues affecting the quality of the entire bulldozer. After pollutants are mixed into the rear axle box, they can easily enter the hydraulic system, which in turn leads to an increase in the failure rate of the hydraulic system and affects the normal operation of the vehicle.

[0003] Therefore, the rear axle box needs to be cleaned regularly. The existing rear axle box cleaning device generally includes four parts: cleaning, filtering, oil return and circulation. Among them, the oil return part is generally a funnel held by a special person, so that the funnel is attached to the bottom of the rear axle to collect the oil flowing out of the hole at the bottom of the rear axle. However, this method requires two people to cooperate in the cleaning process of the rear axle box, which wastes labor and cannot work continuously for a long time, greatly reducing work efficiency. Utility model content:

[0004] In order to solve the above technical problems, the utility model provides a rear axle cleaning device, which solves the technical problem that the oil return part requires a dedicated person to operate, resulting in the cleaning process of the rear axle box requiring two people to cooperate, wasting labor, and unable to work continuously for a long time, greatly reducing work efficiency. In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] The rear axle cleaning device comprises a spray gun, a first hose, a power mechanism, a filter device, an oil tank, a filter bag, a second hose, and a connecting structure which are connected in sequence. One end of the water inlet of the spray gun is connected to the first hose, one end of the first hose is connected to one end of the power mechanism, the other end of the power structure is connected to the filter device, the filter device is connected to the oil tank, the oil tank is connected to the filter bag, a second hose is inserted into the filter bag, and the end of the second hose away from the filter bag is connected to the connecting structure. The connecting structure comprises:

[0006] A first suction cup, wherein the first suction cup is provided with an air nozzle protruding outward;

[0007] A second suction cup, the second suction cup is arranged inside the first suction cup, the bottom of the second suction cup is connected to the bottom of the first suction cup in a fixed structure, and a cavity capable of forming negative pressure is provided between the second suction cup and the first suction cup;

[0009] The conduit has an upper portion connected to the bottom of the second suction cup in a fixed structure, and a lower end surface of the conduit extends into the filter screen.

[0010] Furthermore, the upper end surface of the first suction cup is flush with the upper end surface of the second suction cup.

[0011] Furthermore, the first suction cup and the second suction cup are both made of rubber.

[0012] Furthermore, both the upper end surface of the first suction cup and the upper end surface of the second suction cup are horizontally provided with edges.

[0013] Furthermore, the conduit passes through the bottom of the second suction cup and extends to be flush with the upper end surface of the second suction cup.

[0014] The beneficial effects of the utility model are as follows: the cavity is made into a negative pressure zone by squeezing, so that the suction cup is adsorbed on the bottom of the rear axle to prevent the suction cup from falling off; the double-layer suction cup design can prevent pollutants such as oil from entering the cavity, thereby affecting the adsorption effect of the suction cup; in summary, the device only needs one person to operate during the cleaning process, saving labor, and can work continuously for a long time, greatly improving work efficiency.

[0019] In order to make the purpose, technical scheme and advantages of the implementation of the utility model clearer, the utility model will now be further described in detail with reference to the accompanying drawings and the following examples so that the public can better understand the implementation method of the utility model. The specific implementation scheme of the utility model is as follows:

[0020] The rear axle cleaning device includes a spray gun 8, a first hose 9, a power mechanism 10, a filter device 11, an oil tank 12, a filter bag 13, a second hose 14, and a connecting structure which are connected in sequence. One end of the water inlet of the spray gun 8 is connected to the first hose 9, one end of the first hose 9 is connected to one end of the power mechanism 10, the other end of the power structure 10 is connected to the filter device 11, the filter device 11 is connected to the oil tank 12, the oil tank 12 is connected to the filter bag 13, a second hose 14 extends into the filter bag 13, and the end of the second hose 14 away from the filter bag 13 is connected to the connecting structure.

[0021] Preferably, the connecting structure includes a first suction cup 1; a second suction cup 2 is arranged inside the first suction cup 1, and a double-layer suction cup design is adopted to prevent pollutants such as oil from affecting the adsorption effect of the suction cup; the bottom of the second suction cup 2 is connected to the bottom of the first suction cup 1 in a fixed structure manner, and a cavity 5 that can form a negative pressure is provided between the second suction cup 2 and the first suction cup 1, and the cavity 5 can be changed into a negative pressure state by extrusion, so that the suction cup is adsorbed on the bottom of the rear axle to prevent the suction cup from falling off; a conduit 4 is arranged at the bottom of the second suction cup 2, and the upper part of the conduit 4 is connected to the bottom of the second suction cup 2 in a fixed structure manner, and the lower end face of the conduit 4 extends into the filter; an outwardly protruding air nozzle 7 is opened on the first suction cup 1, and a one-way valve 3 is arranged in the air nozzle 7, and the one-way valve 3 is used to discharge the gas in the cavity 5 and ensure that no air will enter the cavity 5 under the negative pressure state to avoid affecting the negative pressure effect of the cavity 5.

[0022] Specifically, the upper end surface of the first suction cup 1 is flush with the upper end surface of the second suction cup 2, so as to prevent the cavity 5 from being connected to the outside through the space formed by the second suction cup 2 and the bottom of the rear axle during squeezing, and the outside gas from entering the cavity 5, thereby preventing the cavity 5 from reaching a negative pressure state.

[0023] It should be explained that the first suction cup 1 and the second suction cup 2 are both made of rubber material. Rubber material has good plasticity and can undergo plastic deformation under the action of external force and return to its initial state after the external force disappears. Therefore, no matter whether the cavity 5 is in a negative pressure state or a normal state, the first suction cup 1 and the second suction cup 2 can adapt normally, which not only ensures the adsorption effect, but also does not cause damage to the suction cup structure due to deformation, thereby ensuring the durability of the suction cup.

[0024] Preferably, the upper end surfaces of the first suction cup 1 and the second suction cup 2 are both horizontally provided with edges 6, and the edges 6 increase the contact area between the first suction cup 1 and the second suction cup 2 and the bottom of the rear axle, so that the suction cups can adsorb more stably.

[0025] Furthermore, the conduit 4 passes through the bottom of the second suction cup 2 and extends to be flush with the upper end surface of the second suction cup 2. When in use, the conduit 4 can be inserted into the oil outflow hole at the bottom of the rear axle to allow the oil to directly enter the conduit, thereby improving the oil collection efficiency.

[0026] The working principle and working process of the utility model are as follows:

[0027] When in use, align the conduit 4 with the oil outflow hole at the bottom of the rear axle, the upper end surfaces of the first suction cup 1 and the second suction cup 2 are in contact with the bottom of the rear axle, and the conduit 4 is pushed upward to insert into the oil outflow hole at the bottom of the rear axle. At the same time, the conduit 4 moves upward to apply an upward force to the first suction cup 1 and the second suction cup 2, which causes the first suction cup 1 and the second suction cup 2 to deform and squeeze the cavity 5, and discharge the air in the cavity 5 to the outside through the one-way valve 3. At this time, the cavity 5 forms a negative pressure state, and the suction cup is adsorbed to the bottom of the rear axle.

[0028] At the end of use, an iron sheet is inserted between the edge of the first suction cup and the bottom of the rear axle to open a gap so that air can enter the cavity 5. When the negative pressure state is removed, the suction cup can be removed.
