[0002] A hydraulic system refers to a system that uses oil as a working medium, utilizes the pressure energy of the oil, and drives the hydraulic actuators through control valves and other components. The hydraulic system consists of five parts, namely power elements, actuators, control elements, auxiliary elements, and hydraulic oil. Hydraulic equipment is the combination of these parts, and hydraulic oil is the most important part of hydraulic equipment.

[0003] After long-term use, the metal parts in the hydraulic system will wear against each other, causing a certain amount of metal chips or other impurities to be mixed in the hydraulic oil. If these impurities are not cleaned and filtered out in time, the wear between the parts will be aggravated, thereby shortening the service life of the parts. Utility Model Content

[0004] In order to overcome the above defects, the utility model provides a filtering device for hydraulic oil delivery, which solves the problem that after long-term use, the hydraulic oil will be mixed with a certain amount of metal chips or other impurities. If these impurities are not cleaned and filtered out in time, the wear between parts will be aggravated.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a filter device for conveying hydraulic oil, comprising a mounting frame, a lower tank body is mounted on the mounting frame, a first fixing block is connected to the lower tank body, end covers are connected to both sides of the lower tank body, a plurality of positioning strips are connected to the inner wall of the lower tank body, an upper tank body is rotatably connected to the lower tank body, a second fixing block is connected to the upper tank body, a liquid inlet pipe is connected to the end cover on one side of the lower tank body, a liquid outlet pipe is connected to the end cover on the other side of the lower tank body, and a mounting plate is connected to the end cover;

[0008] As a further solution of the utility model: an elastic plate is connected to the second clamping plate, a clamping block is connected to the elastic plate, and a clamping slot is provided on the first clamping plate.

[0009] As a further solution of the utility model: the first clamping plate and the second clamping plate are specifically arranged between two positioning strips, and a filter cotton plate is installed between the first clamping plate and the second clamping plate.

[0010] As a further solution of the utility model: the four elastic plates are symmetrical about the center of the second clamping plate, the clamping block is triangular in design and fits into the clamping groove, and the first fixing block and the second fixing block are both provided with threaded holes.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The hydraulic oil transmission filtering device is provided with a motor, a rotating rod, a stirring rod, a magnet, a first filter hole, a second filter hole and a filter cotton plate. The hydraulic oil enters from the liquid inlet pipe. At this time, the motor drives the rotating rod to rotate, so that the stirring rod can stir the hydraulic oil in the liquid inlet pipe area, so that the impurities or metal chips in the hydraulic oil can be evenly distributed to avoid the precipitation of impurities or metal chips. While stirring, the magnet will absorb the metal chips in the hydraulic oil. Then the hydraulic oil will pass through the first filter hole and the second filter hole, and the filter cotton plate between the first clamping plate and the second clamping plate will filter out the impurities in the hydraulic oil, thereby avoiding the metal chips and impurities from wearing metal parts and ensuring the service life of the parts.

[0014] 2. The filtering device for conveying hydraulic oil is provided with a fixed plate, a slide groove, a slide plate, a notch groove, an elastic plate, a block and a slot. The staff pushes the magnet to make the slide plate disengage from the slide groove, thereby removing the magnet from the fixed plate, making it convenient for the staff to clean and scrape off the metal chips, and avoiding excessive metal chips due to long-term use, which may lead to a decrease in the adsorption capacity of the magnet. The staff pushes the first clamping plate and the second clamping plate through the notch groove, so that the slot wall on the first clamping plate can squeeze the block through the triangular inclined surface of the block, causing the elastic plate to deform, thereby separating the first clamping plate and the second clamping plate, allowing the staff to replace the filter cotton plate, and avoiding a decrease in the filtering effect due to long-term use.
