Technical Field

[0001] The present invention relates to the technical field of air conditioners, and more particularly to an excavator air conditioner which is convenient for replacing an inner filter element. Background Art

[0002] An excavator is an earth-moving machine that uses a bucket to dig soil, coal, silt, or pre-loosened soil and rocks above or below the bearing surface, and loads them into transport vehicles or unloads them to stockpiles. It has become one of the most important construction machinery in engineering construction. The working environment of an excavator is relatively harsh, which is not conducive to operators working with windows open in the cab. Usually, air conditioners are installed in the excavator cab to increase the comfort of the operator.

[0024] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0025] The same parts are denoted by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the drawings, and the words "bottom" and "top", "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0026] As shown in the figure, an excavator air conditioner which is easy to replace the inner filter element includes an air conditioner main unit 1, an air outlet pipe 2 is arranged on one side, a connecting sleeve 3 is sleeved and fixedly connected on the air outlet pipe 2, a mounting sleeve 4 is arranged on the outer surface of the connecting sleeve 3, the mounting sleeve 4 includes a bottom rod 5, two side rods 6 and a top rod 7, the top rod 7 is provided with a slot 8 penetrating the upper and lower surfaces thereof along its length direction, a filter element 9 is inserted into the mounting sleeve 4 through the slot 8, sliding rods 10 are arranged on the four corners of the mounting sleeve 4 facing the connecting sleeve 3, sliding grooves 11 for sliding connection of the sliding rod 10 are arranged on the four outer corners of the connecting sleeve 3, and a driving component for driving the sliding rod 10 is also included. After installation, the mounting sleeve 4 provided with the filter element 9 is located in the air outlet of the air conditioner in the cab to further filter the discharged cold air.

[0027] When the excavator air conditioner is used for a long time and the filter element 9 needs to be replaced, the driving assembly drives the sliding rod 10 to move toward the air outlet, thereby driving the mounting sleeve 4 to move toward the outside of the air outlet and thus extending out of the cockpit air outlet, so that the driver can directly remove the filter element 9 from the mounting sleeve 4 and reinsert the new filter element 9 to improve the convenience of replacing the filter element 9.

[0028] The bottom rod 5 is provided with a guide groove 12 along its length direction, which passes through the surface of the bottom rod 5 facing the connecting sleeve 3. A guide block 13 is slidably connected in the guide groove 12. A horizontally arranged hinged rod 14 is hingedly connected to the surface of the guide block 13 facing the connecting sleeve 3. A groove 15 is provided at the bottom of the connecting sleeve 3, which passes through the bottom rod 5 facing the mounting sleeve 4. One end of the hinged rod 14 is hingedly connected to the bottom of the groove 15, and a driving member for driving the guide block 13 is also included. The driving member is specifically an electric push cylinder 16 arranged at one end of the guide groove 12, and the end of its telescopic rod is fixedly connected to the guide block 13.

[0029] The guide block 13 is pushed by the electric push cylinder 16 to slide along the guide groove 12, causing the hinged rod 14 to deflect, so that it pushes the installation sleeve 4 to move in the direction away from the connecting sleeve 3, and finally makes the installation sleeve 4 extend out of the air outlet of the air conditioner to allow the driver to replace the filter element 9. After replacing the filter element 9, the electric push cylinder 16 drives the guide block 13 to reset, and under the action of the hinged rod 14, drives the installation sleeve 4 to move toward the connecting sleeve 3 again, and finally fits the outer surface of the connecting sleeve 3.

[0030] A positioning strip 17 covering the top of the installation sleeve 4 is provided on the top of the outer side of the connecting sleeve 3 . When the installation sleeve 4 is attached to the outer surface of the connecting sleeve 3 , the positioning sleeve covers the top of the installation sleeve 4 to position the filter element 9 .

[0031] A lifting block 18 is provided at the bottom of the filter element 9, and a through groove 19 connected to the guide groove 12 is provided on the surface of the bottom rod 5. The lifting block 18 passes through the through groove 19 and is located in the guide groove 12. A first inclined surface 20 is provided at one end of the guide block 13 facing the lifting block 18, and a second inclined surface 21 is provided at one end of the lifting block 18 facing the guide block 13. The guide block 13 slides toward the lifting block 18, and under the action of the first inclined surface 20 and the second inclined surface 21, the lifting block 18 and the filter element 9 are driven to move upward.

[0032] After the mounting sleeve 4 and the connecting sleeve 3 are installed in place, the positioning strip 17 is placed on the top of the mounting sleeve 4, a certain distance is left between the first inclined surface 20 and the second inclined surface 21, the guide block 13 moves toward the lifting block 18, and after the first inclined surface 20 contacts the second inclined surface 21, the positioning strip 17 is completely separated from the mounting sleeve 4.

[0033] When the electric push cylinder 16 drives the guide block 13 to move, it drives the installation sleeve 4 to move away from the connecting sleeve 3 under the action of the hinged rod 14. When the positioning bar 17 is completely separated from the installation sleeve 4, the first inclined surface 20 abuts against the second inclined surface 21, and the electric push cylinder 16 continues to drive the guide rod to move. While the installation sleeve 4 continues to move away from the connecting sleeve 3, under the action of the first inclined surface and the second inclined surface 21, the filter element 9 is driven to rise and extend out of the slot 8, thereby facilitating the driver to directly take out the filter element 9 and replace it with a new filter element 9.

[0034] A rubber sealing ring 22 is provided along the circumference of the surface of the installation sleeve 4 facing the connection sleeve 3 to improve the sealing between the installation sleeve 4 and the connection sleeve 3 after installation, so as to ensure the air outlet effect of the air conditioner.

[0035] A limiting groove 23 for the guide block 13 to be slidably connected is provided at the bottom of the guide groove 12, and the top of the guide block 13 is slidably connected in the through groove 19 to ensure the stability of the guide block 13 during operation.
