Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0023] The integrated water and fertilizer machine is a modern agricultural device that combines irrigation and fertilization. By precisely controlling the supply of water and nutrients, it achieves the goals of water and fertilizer conservation, increased yield and efficiency. The equipment uses sensors to monitor parameters such as soil moisture and EC value in real time, and automatically adjusts the fertilizer concentration and delivers it evenly to the root zone based on the crop's growth needs. Compared with traditional irrigation methods, this technology can save 30%-50% of water and 40%-60% of fertilizer, while reducing labor costs and improving crop quality. It is widely used in greenhouses, orchards, and field planting, and is particularly effective in arid regions and large-scale agricultural production. The main function of the small integrated water and fertilizer machine is to mix fertilizers from different types of fertilizer tanks in a certain proportion and discharge them into the main pipe, which then transports them to the irrigation area. During this process, the inventors discovered that the water used to dissolve fertilizers in the fertilizer tanks, usually river water or well water, contains certain impurities, and the fertilizers themselves also carry some impurities. It is best to remove these impurities before they enter the main unit to prevent damage to the main unit and pipelines and to extend their service life.

[0024] First embodiment:

[0025] like Figure 1-3 As shown, the filtration device for the water and fertilizer integrated machine provided by this utility model includes: a connecting pipe (20) and a telescopic pipe 10 threaded on the connecting pipe 20. The connecting pipe 20 is used to be installed on the pipeline connecting the fertilizer tank and the main unit. The telescopic pipe 10 can move left and right on the connecting pipe 20 by means of the thread on its inner wall. A filter 30 is detachably provided inside the connecting pipe 20. The filter 30 is used to filter impurities in the water.

[0026] Specifically, the telescopic tube 10 is cylindrical with openings at both ends, and the inner wall of the tube at the openings has threads, such as... Figure 3 As shown, its structure is symmetrical from left to right;

[0027] The connecting pipe 20 is also a cylindrical structure with openings at both ends. The outer wall of the connecting pipe 20 has the same inner diameter as the telescopic pipe 10. One end is fixed to the end of the water pipe by heat fusion or interference fit. The outer wall of the other end is screwed into the telescopic pipe 10 through a thread that matches the inner wall of the telescopic pipe 10. The connecting pipes 20 at both ends of the telescopic pipe 10 are configured in this way. Figure 3 Based on the shown state, assuming the water flow direction is from left to right, a baffle 21 is fixedly installed at the pipe opening of a connecting pipe 20 on the right side. The function of the baffle 21 is to block the filter 30 installed on its left side.

[0028] The filter 30 is a device for filtering impurities in water. It consists of two parts: a first ring 31 that is circular and a filter screen 32 with its opening edge tied to the first ring 31. The filter screen 32 is made of cotton cloth and has small holes on its surface. The outer diameter of the first ring 31 is slightly smaller than the inner diameter of the connecting pipe 20. Therefore, the filter 30 can be placed inside the connecting pipe 20 and its position is blocked and restricted by the baffle 21 on its inner wall.

[0029] like Figure 2 As shown, when the telescopic tube 10 rotates and moves to the left, the telescopic tube 10 gradually separates from the connecting tube 20 on its right side and eventually disconnects, thus exposing the filter 30 located inside the connecting tube 20 on the right side. At this time, the staff can remove the filter 30, clean the impurities inside it, and then reinstall it.

[0030] The filter 30 installed in the connecting pipe 20 can effectively remove impurities from the water, and the filter 30 can be removed from the connecting pipe 20 for easy cleaning and replacement.

[0031] Second embodiment:

[0032] like Figure 3 As shown, an inner tube 12 is fixed at both ends of the outer tube 11. The end of the inner tube 12 near the opening of the outer tube 11 is close to the end of the outer tube 11, and its outer diameter is smaller than the inner diameter of the outer tube 11. The end of the inner tube 12 inside the outer tube 11 has a thicker wall, and its outer diameter is the same as the inner diameter of the outer tube 11 and is bonded and fixed to the inner wall of the outer tube 11. This forms a gap between the outer tube 11 and the inner tube 12. This gap is the jacking area 13 for the connecting tube 20 to enter. At the same time, the wall of the inner tube 12 enters the connecting tube 20 and the end of the inner tube 12 contacts and applies pressure to the first retaining ring 31 located inside the connecting tube 20.

[0033] The inner tube 12 is used to fix the filter 30 and prevent it from moving under the push of water flow. In addition, the inner tube 12 increases the contact area between the expansion tube 10 and the wall of the connecting tube 20, and the connection between the two is more airtight.

[0034] Third embodiment:

[0035] This embodiment is another way to increase the pressure between the baffle 21 and the first baffle ring 31 to ensure that the filter 30 is stably installed inside the connecting pipe 20. Magnetic strips are pasted on the surfaces of the baffle 21 and the first baffle ring 31, and the magnetic strips are all magnetic and attract each other.

[0036] Fourth embodiment:

[0037] like Figure 2A second retaining ring 14 is fixed to the outer wall of the connecting pipe 20. The second retaining ring 14 can contact the end of the outer pipe 11. The second retaining ring 14 prevents the telescopic pipe 10 from moving further on the right side of the connecting pipe 20. When the right end face of the telescopic pipe 10 contacts the second retaining ring 14, the inner pipe 12 contacts the first retaining ring 31 on the filter 30 simultaneously.

[0038] By setting the second retaining ring 14, the position of the telescopic tube 10 on the connecting tube 20 is constrained on the one hand, and the contact area between the connecting tube 20 and the telescopic tube 10 is increased on the other hand, resulting in a better sealing effect.

[0039] In use, first weld the left end connecting pipe 20 of the device to the disconnected water pipe, then install the right end connecting pipe 20 on another water pipe, and rotate the telescopic pipe 10 to move it to the left. Figure 3 Status transition Figure 2 Install the filter 30 inside the connecting pipe 20 on the right side. Finally, rotate the telescopic pipe 10 in the opposite direction so that its end contacts and presses against the second retaining ring 14 on the connecting pipe 20 on the right side. When it is necessary to clean the impurities inside the filter 30, remove the filter 30 in the above manner.

[0040] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
