DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Example

[0035] A drip irrigation filter device with good filtering effect, such as Figure 1 to Figure 2 As shown, it includes a shell 1, a stirring assembly, and a self-cleaning filtering mechanism; a water inlet 10 is provided on the top side of the shell 1, and a water outlet 4 is provided on the bottom side; the stirring assembly and the self-cleaning filtering mechanism are both arranged in the shell 1 and connected to each other; wherein the water outlet 4 is used to connect the drip irrigation device 3.

[0036] The stirring assembly includes a stirring shaft 11 and a stirring blade 8, and the self-cleaning filtering mechanism includes a reversing assembly 2, a driving rod 7, a cleaning rod 6 and a filter 5; the stirring shaft 11 and the filter 5 are respectively arranged on both sides of the housing 1 and are both arranged vertically, the stirring shaft 11 is rotatably connected to one side of the housing 1 close to the water inlet 10, and the filter 5 is located on the other side, the stirring blade 8 is connected to the stirring shaft 11, and one side of the stirring shaft 11 extends out of the housing 1 and is connected to the driving device; the stirring blade 8 is used to stir and assist in dissolving the water-soluble fertilizer, and at the same time, the water in the housing 1 continues to flow, so that the impurities in the water continue to move, which can effectively prevent the impurities from adhering to the inner surface of the housing 1 or adhering to the filter 5, and ensure the filtering effect of the filter 5. The driving device is used to drive the stirring shaft 11 to rotate.

[0037] The reversing assembly 2 is arranged between the stirring shaft 11 and the filter screen 5 and the reversing assembly 2 is connected to the stirring shaft 11, the driving rod 7 is connected to the reversing assembly 2 and is arranged horizontally, the cleaning rod 6 is connected to the end of the driving rod 7, and the cleaning rod 6 is provided with bristles, and the bristles are in contact with the filter screen 5; wherein the reversing assembly 2 is used to make the driving rod 7 and the stirring shaft 11 rotate synchronously, for example, the reversing assembly 2 can adopt a bevel gear structure, and the design of the bevel gear can make the vertical stirring shaft 11 drive the horizontal driving rod 7 to rotate.

[0038] Specifically, in actual use, water for drip irrigation is introduced into the housing 1 through the water inlet 10. The driving device is started, and the driving device drives the stirring shaft 11 to rotate, and the stirring shaft 11 drives the circumferential stirring blades 8 to rotate, and the stirring blades 8 stir the water in the housing 1 to accelerate the dissolution of the undissolved water-soluble fertilizer in the water. When the stirring shaft 11 rotates, the stirring shaft 11 drives the driving rod 7 to rotate through the reversing component 2, and the driving rod 7 drives the cleaning rod 6 to rotate. When the cleaning rod 6 rotates, it will clean the surface of the filter screen 5 through the brush on the surface, thereby preventing foreign particles from adhering to the filter screen 5. In addition, by vertically arranging the filter screen 5, the possibility of impurities adhering to the filter screen 5 can be effectively reduced. Since the relative mass of the undissolved water-soluble fertilizer and most of the impurities is greater than that of water, most of the impurities will settle to the bottom more easily in the housing 1. Therefore, the vertically arranged filter screen 5 can effectively prevent the settled impurities or undissolved water-soluble fertilizer from clogging the filter screen 5. Keeping the filter screen 5 transparent means ensuring the filtering effect. The vertically arranged filter screen 5 and the design of the self-cleaning filter mechanism can effectively prevent the filter screen 5 from being blocked, thereby ensuring the filtering effect, that is, making the filtered water cleaner and effectively preventing the drip irrigation pipe in the drip irrigation device 3 from being blocked.

[0039] In a preferred embodiment, if Figure 1 to Figure 2 As shown, a feeding port 15 is provided at the top of the housing 1 near the water inlet 10. The feeding port 15 is provided to facilitate the feeding of water-soluble fertilizers. The design of the feeding port 15 makes it unnecessary to prepare fertilizer water in advance. It is only necessary to pour water through the water inlet 10 while feeding water-soluble fertilizers through the feeding port 15, which can effectively improve work efficiency.

The design of the rotating shaft 14 can facilitate the installation of the reversing assembly 2.

[0042] In a preferred embodiment, if Figure 1 to Figure 2As shown, the housing 1 is provided with a mixing chamber 17, a first filter chamber 181, a transfer chamber 19 and a second filter chamber 182 which are interconnected from top to bottom;

The transfer chamber 19 is used to ensure that the water inlet positions of the first filter chamber 181 and the second filter chamber 181 are located on the same side, so as to facilitate the setting of the stirring shaft 11, so that one stirring shaft 11 can be connected to the first reversing component 201 and the second reversing component 202 at the same time.

[0046] The two sets of self-cleaning filtering mechanisms are provided to improve the filtering effect. Specifically, when in use, water enters the mixing chamber 17 from the water inlet 10, the water in the mixing chamber 17 flows into the first filter chamber 181, the first stirring blade 801 stirs the water in the first filter chamber 181 and accelerates the dissolution of the water-soluble fertilizer, and the brush on the first cleaning rod 601 cleans the first filter net 501.

The second stirring blade 802 continues to stir so that the tiny water-soluble fertilizer crystals in the water are fully dissolved. The brush on the second cleaning rod 602 cleans the second filter net 502. The water in the second filter chamber 182 is filtered by the filter net 5 and then flows out through the water outlet 4. The filtering effect can be effectively improved by filtering twice.
