The following is an explanation of an embodiment of the present invention based on the overall structure of the present invention.

[0029] See also Figures 1 to 8 In an embodiment of the present invention, a filtering system for forestry irrigation includes a connecting water pipe 1 and a valve body 2, and the valve body 2 is installed on the outer wall of the connecting water pipe 1. The valve body 2 is a three-way structure, and the two side ports of the valve body 2 are respectively a water inlet and a water outlet. An L-shaped pipe rack 201 is sleeved in the water inlet, and the horizontal end of the L-shaped pipe rack 201 fits the inner wall of the water inlet of the valve body 2 and is connected to the water inlet end of the connecting water pipe 1, and the water outlet of the valve body 2 is connected to the water outlet end of the connecting water pipe 1; an annular countersunk hole is opened at the top of the valve body 2, and a valve cover 3 is inserted in the countersunk hole through a self-lubricating sealing ring, and a filter element is installed in the inner cavity of the valve cover 3, and the vertical end of the L-shaped pipe rack 201 extends to the top opening of the valve body 2 and docks with the filter element. The filter element is composed of a core frame 4 and a disc 5 for filtering (the disc is a filter membrane). The disc 5 is sleeved on the outer wall of the core frame 4. The valve cover 3 and the filter element are installed and removed through a moving mechanism 6. The disc 5 is flushed through a flushing mechanism 7.

[0030] The moving mechanism 6 includes a connecting block 601 and a base plate 603. The connecting block 601 is slidably connected to the inner wall of the valve cover 3. The bottom end of the connecting block 601 is fixedly connected to two connecting frames 602. The core frame 4 is slidably connected between the two connecting frames 602. The base plate 603 is arranged at the bottom end of the connecting water pipe 1. The top of the base plate 603 is fixedly connected to a mounting frame 604. A displacement groove 605 is provided on the outer wall of the mounting frame 604. A displacement seat 606 is slidably connected to the inner wall of the displacement groove 605. A motor 607 is installed on the outer wall of the mounting frame 604. The output end of the motor 607 is connected to a threaded rod 608 for driving the displacement seat 606 to move. A first electric push rod 609 is installed on the top of the displacement seat 606. The valve cover 3 is connected to the output end of the first electric push rod 609.

[0031] In this embodiment: when the device is performing water filtering operations, unfiltered raw water enters the horizontal end of the L-shaped pipe rack 201 from the water inlet end connected to the water pipe 1, and then enters the core rack 4 of the filter element through the vertical end of the L-shaped pipe rack 201. After being filtered by the multi-layer discs 5, the clean water passes through the filter element and enters the water outlet end connected to the water pipe 1 for use in irrigation and spraying operations, while impurities contained in the raw water are blocked in the discs 5 and the core rack 4.

[0032] When the laminated filter is disassembled, the first electric push rod 609 is started, and the first electric push rod 609 drives the valve cover 3 to move upward. At this time, the connecting block 601 slides on the inner wall of the valve cover 3 until it slides to the bottom end of the valve cover 3. The connecting block 601 moves upward synchronously with the valve cover 3, and the connecting block 601 pulls the core frame 4 to move synchronously (such as Figure 4As shown), when the filter element is separated from the valve body 2, the motor 607 can be started to drive the threaded rod 608 to rotate, and the threaded rod 608 rotates to drive the displacement seat 606 to move, and the displacement seat 606 moves to move the valve cover 3 and the filter element to the position of the flushing mechanism 7 for flushing operation.

[0033] After flushing is completed, the motor 607 drives the displacement seat 606 to move and reset, and the first electric push rod 609 drives the valve cover 3 to move downward. The valve cover 3 and the filter element are respectively in contact with the valve body 2 and the L-shaped pipe rack 201. At this time, the top of the inner wall of the valve cover 3 squeezes the connecting block 601, and the displacement of the connecting block 601 drives the connecting rack 602 to move. The connecting rack 602 moves and contacts with the disc 5, and the disc 5 is pressed (such as Figure 3 As shown), it is convenient to automatically disassemble and install the valve cover 3 and the filter element of the laminated filter.

[0034] Please refer to Figures 5 to 8 The flushing mechanism 7 includes a connecting seat 701, which is fixedly connected to one end of the mounting frame 604. A slide groove 702 is provided at the bottom end of the connecting seat 701. A movable frame 703 is slidably connected to the inner wall of the slide groove 702. A nozzle 704 is installed at one end of the bottom of the movable frame 703. A water inlet connecting pipe 705 is connected to the other end of the bottom of the movable frame 703. The water inlet connecting pipe 705 is connected to the nozzle 704. A second electric push rod 706 is installed at the top of the bottom of the movable frame 703. A push plate 707 is connected to the output end of the second electric push rod 706. Both sides of the bottom end of the push plate 707 are symmetrically rotatably connected with connecting rods 708 through a rotating axis. One end of the connecting rod 708 is rotatably connected to the middle part of a rotating rod 709. One end of the rotating rod 709 is rotatably connected to the movable frame 703. The flushing mechanism 7 also includes a tooth plate 710, which is slidably connected to the inside of the connecting seat 701 and is located on one side of the slide groove 702. The outer wall of the tooth plate 710 is fixedly connected to a push rod 711, one end of the push rod 711 extends to the inner cavity of the displacement groove 605, and the outer wall of the push rod 711 between the tooth plate 710 and the mounting frame 604 is connected to a first spring 712. The interior of the movable frame 703 is slidably connected to a block 713 extending from one side of the movable frame 703, and the block 71 A second spring 714 is connected between the movable frame 703 and the movable frame 703, a spur gear 715 extending from the other side of the movable frame 703 is rotatably connected inside the movable frame 703, an "L"-shaped displacement frame 716 is slidably connected inside the movable frame 703, a third spring 717 is connected between the displacement frame 716 and the movable frame 703, a vertical plate 718 that can move laterally is slidably connected to the outer wall of the displacement frame 716, and a fourth spring 719 is connected between the vertical plate 718 and the displacement frame 716.

[0035] In this embodiment: when the displacement seat 606 moves to one end of the displacement groove 605, it drives the filter element to move to one side of the nozzle 704 and the rotating rod 709. At this time, the displacement seat 606 is displaced and contacts with the top rod 711, pushing the top rod 711 to displace. The displacement of the top rod 711 drives the tooth plate 710 to displace and contact with the block 713, causing the first spring 712 to be stretched.

[0036] At this time, the water in the connecting water pipe 705 is sprayed out through the nozzle 704 to rinse the disc 5, and the second electric push rod 706 can be started to drive the push plate 707 to move. The displacement of the push plate 707 drives the rotating rod 709 to rotate through the connecting rod 708, so that the two rotating rods 709 perform tightening and opening actions; when the rotating rod 709 is tightened, the rotating rod 709 contacts the two discs 5, so that a gap is generated between the two discs 5, and the nozzle 704 performs a flushing operation between the two discs 5; thereafter, when the rotating rod 709 is opened, the push plate 707 moves toward the displacement frame 716, pushing the displacement frame 716 to move, causing the third spring 717 to be squeezed, and the displacement frame 716 moves with The movable vertical plate 718 contacts with the spur gear 715 and drives the spur gear 715 to rotate. The rotation of the spur gear 715 drives the movable frame 703 to move upward a short distance along the slide groove 702. At this time, the block 713 is engaged with the tooth plate 710 under the elastic force of the second spring 714 to prevent the movable frame 703 from moving downward; when the pushing plate 707 is separated from the displacement frame 716, the displacement frame 716 moves downward under the elastic force of the third spring 717. At this time, since the movable frame 703 cannot move downward, the spur gear 715 cannot rotate. The vertical plate 718 is attached to the spur gear 715 under the elastic force of the fourth spring 719 and moves downward at the same time. This is repeated many times, and the flushing operation is performed between each two discs 5 in turn.

[0037] When the flushing is completed, the displacement seat 606 is displaced and reset, and the displacement seat 606 is separated from the top rod 711. The tooth plate 710 is displaced and separated from the block 713 by the elastic force of the first spring 712, and the fixation of the movable frame 703 is cancelled. The movable frame 703 moves downward along the slide groove 702 under the action of gravity to perform the reset operation. This design facilitates the automatic distribution and flushing operation of the disc 5 on the filter element from bottom to top. It should be noted that one end of the water inlet connecting pipe 705 is connected to the water storage device, and a water pump is installed on the outer wall of the water inlet connecting pipe 705.
