[0002] Chinese patent document CN217381129U discloses a hydraulic oil filter for engineering machinery, including a base. The base is equipped with a cleaning mechanism and a support mechanism. The support mechanism includes a concave plate, a insert rod, a base plate, an anti-slip pad, a connecting piece, a pin, and a hydraulic rod. The right side of the outer wall of the concave plate is fixedly connected to the left side of the base. The two ends of the insert rod are fixedly connected to the front and back of the inner wall of the concave plate, respectively. The bottom of the base plate is fixedly connected to the top of the anti-slip pad. A circular hole is opened on the right side of both the base plate and the anti-slip pad. The inner wall of the circular hole is movably fitted onto the outer wall of the insert rod. There are two connecting pieces on one side. By opening the electric push rod, its inner rod drives the connecting rod, the support arm, and the circular block to move left and right in sequence. At the same time, the roller brush contacts the front of the triangular body to wipe the oil, quickly cleaning the oil residue on the surface of the equipment, preventing the surface of the equipment from becoming sticky, and preventing bacterial growth.

[0003] However, the aforementioned oil filter removes all the dripping oil, resulting in low resource recycling rate and oil waste. Therefore, we propose a hydraulic oil filter for engineering machinery. Utility Model Content

[0004] The purpose of this utility model is to provide a hydraulic oil filter for engineering machinery, which can solve the problem of wasting the seepage oil in some existing oil filters.

[0016] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0017] Please see Figure 1-5 This utility model provides a technical solution: a hydraulic oil filter for engineering machinery, including a mounting plate 1, a filter body 13, a limiting mechanism 6, and an adjusting mechanism 5. A displacement plate 2 is attached to the top of the mounting plate 1, and two sets of placement cylinders 3 are fixedly installed on the top of the displacement plate 2. A collection cylinder 4 is attached to each of the two sets of placement cylinders 3. The mounting plate 1 is mounted on the filter body 13, and the limiting mechanism 6 is mounted on the placement cylinders 3. The limiting mechanism 6 is used to limit the position of the collection cylinder 4. A set of weight sensors 7 are fixedly installed on the inner bottom of each of the two sets of collection tubes 3. Each of the two sets of collection tubes 4 is mounted on the corresponding weight sensor 7. Two sets of positioning grooves 8 are opened on the inner wall of each of the two sets of collection tubes 3. Two sets of positioning blocks 9 are fixedly installed on the outer surface of each of the two sets of collection tubes 4. Each set of positioning blocks 9 is inserted into the corresponding positioning groove 8. At least two sets of mounting holes 10 are opened through the mounting plate 1. A buffer pad 11 is fixedly installed on the bottom of the mounting plate 1. An alarm 12 is fixedly installed on the top of the mounting plate 1. The adjustment mechanism 5 is set on the mounting plate 1. The adjustment mechanism 5 includes a strip groove 52, a lead screw 53 and a connecting block 54. The top of the mounting plate 1 has a strip groove 52. The lead screw 53 is rotatably installed between the inner walls of the two sides of the strip groove 52. The bottom of the displacement plate 2 is fixedly installed with a connecting block 54, which is threaded onto the lead screw 53.

[0018] The adjustment mechanism 5 also includes a servo motor 51. The servo motor 51 is fixedly installed on one outer surface of the mounting plate 1. The rotating shaft of the servo motor 51 is connected to the lead screw 53 for transmission. The connecting block 54 is in contact with the inner walls of the front and rear sides of the strip groove 52. Through the cooperation of the collecting cylinder 4 and the adjustment mechanism 5, the oil that has seeped and dripped from the oil filter body 13 can be collected. Two sets of collecting cylinders 4 are set up. When one set of collecting cylinders 4 is full of oil, the other set of empty collecting cylinders 4 can be automatically replaced. The full collecting cylinders 4 are processed to achieve continuous collection and prevent waste. This solves the problem that some existing oil filters remove all the dripping oil, resulting in low resource recycling rate and oil waste, and improves the practicality of the oil filter.

[0019] The limiting mechanism 6 includes a fixing block 61, a connecting rod 62, a limiting ring 63, a positioning rod 64, a pull handle 65, and a spring 66. A fixing block 61 is fixedly installed on the outer surface of each of the two sets of placement cylinders 3. A connecting rod 62 is rotatably installed on the top of each of the two sets of fixing blocks 61. A limiting ring 63 is fixedly installed at one end of each of the two sets of connecting rods 62. Both limiting rings 63 are in contact with the top of the corresponding collection cylinder 4. A positioning rod 64 is movably inserted through each of the two sets of connecting rods 62. A positioning hole is opened on the outer surface of each of the two sets of placement cylinders 3. One end of each positioning rod 64 is inserted into the corresponding positioning hole. A set of handles 65 is fixedly installed at the other end of each positioning rod 64. A set of springs 66 is sleeved on each of the two sets of positioning rods 64. One end of each set of springs 66 is fixedly connected to the corresponding handle 65, and the other end of each set of springs 66 is fixedly connected to the outer surface of the corresponding connecting rod 62. Through the limiting mechanism 6, the stability of the collection cylinder 4 placed in the placement cylinder 3 can be improved. At the same time, under the action of the positioning groove 8, the positioning block 9 and the buffer pad 11, the vibration of the mounting plate 1 during operation can be reduced, and the collection cylinder 4 can be prevented from being affected by vibration and causing wear. This ensures the effectiveness of the oil filter and is conducive to the promotion and use of the oil filter.

[0020] Working principle: The mounting plate 1 is installed on the main body 13 of the oil filter through the mounting hole 10, so that one set of collection cylinders 4 is directly opposite the position where the oil seeps into the main body 13 of the oil filter when it is working. When the main body 13 of the oil filter is working, the oil drips continuously into the corresponding collection cylinder 4. When the corresponding weight sensor 7 detects that a certain amount has been collected, it will control the servo motor 51 to start the drive screw 53 to rotate, which drives the connecting block 54 and the displacement plate 2 to move. This moves the collection cylinder 4 full of oil to one side, and the other set of empty collection cylinders 4 moves to the position where the oil drips to continue collecting oil. The alarm 12 will then sound an alarm to remind the staff to clean up the collected oil. That is, pull the corresponding handle 65 to drive the corresponding positioning rod 64 to disengage from the positioning hole on the corresponding placement cylinder 3. At this time, the corresponding connecting rod 62 can be rotated to release the limit ring 63 on the collection cylinder 4 full of oil. Then the collection cylinder 4 can be removed to recover the oil. This process is repeated.

[0021] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
