[0019] Figures 1-4 It is the best embodiment of the utility model, the following will be further explained in connection with the drawings Figure 1 ~ the Figure 4 The utility model will be further explained.

[0020] The utility model discloses a seedling cultivation drip irrigation device, including the main pipe 1, the main pipe 1 is fixedly installed with a plurality of branch pipes 2 in a row equidistance on the main pipe 1, the other end of every branch pipe 2 all is provided with the dripper 3, every dripper 3 all is provided with the filter assembly 4 of filtering the water that enters dripper 3 from branch pipe 2 and the protection assembly 5 of preventing the external dust and impurity from entering dripper 3, dripper 3 includes connecting shell 301, shell 302, outlet pipe 303 and water outlet 304, connecting shell 301 and shell 302 are formed storage cavity through thread connection, connecting shell 301 and the other end of branch pipe 2 are communicated and fixed, one end of outlet pipe 303 and shell 302 are communicated and fixed, the other end of outlet pipe 303 is sealed, and water outlet 304 is set up on outlet pipe 303, filter assembly 4 is set up in shell 302, and protection assembly 5 is set up in outlet pipe 303, and water outlet 304 is blocked.

[0021] In the embodiment, one end of the main pipe 1 is sealingly arranged, the other end of the main pipe 1 is externally connected with a water pump, the main pipe 1 and the branch pipes 2 are made of PE material, when installing, the staff places the main pipe 1 beside the seedlings, and places the drippers 3 close to the stems of the seedlings, at this time, the water pump externally connected pressurizes and delivers the water to the main pipe 1, so that the flow rate of the water is constant, and the water is delivered to each branch pipe 2 through the main pipe 1, and enters the storage cavity in the connecting shell and the shell 302 through thread connection, the water in the storage cavity is filtered by the filter assembly 4, the impurities in the water are filtered, the filtered water in the storage cavity enters the outlet pipe 303, in the initial state, the protection assembly 5 blocks the water outlet 304, when the water in the storage cavity enters the outlet pipe 303 and pushes the protection assembly 5, the protection assembly 5 moves along the inner wall of the outlet pipe 303 and elastically deforms, so that the outlet pipe 303 gradually does not block the water outlet 304, the water flows out through the water outlet 304, and drops on the surface of the soil above the roots of the seedlings, when the drip irrigation is completed, the water pump stops working, when the flow rate of the water cannot push the protection assembly 5, at this time, the protection assembly 5 rebounds, so that the protection assembly 5 assembly returns to the initial state and blocks the water outlet 304, thereby preventing the dust and impurities outside and the insects from entering the outlet pipe 303 through the water outlet 304, when the filter assembly 4 filters too many impurities in the water, thereby affecting the flow rate of the water, at this time, the staff unthreads the thread connection between the connecting shell 301 and the shell 302, so that the filter assembly 4 is exposed, thereby cleaning the impurities on the filter assembly 4, the outer part of the shell 302 is fixedly sleeved with a sealing ring, when the connecting shell 301 and the shell 302 are threadedly connected, the sealing ring seals the connection between the connecting shell 301 and the shell 302, thereby ensuring the sealing property of the connection.

[0022] Specifically, the filtering assembly 4 comprises a fixed block 401 and a filter screen 402, the fixed block 401 is fixedly installed on the inner wall of the shell 302, and the filter screen 402 is connected with the fixed block 401 through bolts, and the frame of the filter screen 402 abuts against the inner wall of the shell 302.

[0023] In the embodiment, when water enters the storage cavity through the branch pipe 2 and needs to enter the water outlet pipe 303, the water is filtered through the filter screen 402, so that impurities in the water are prevented from entering the water outlet pipe 303 and causing blockage of the water outlet pipe 303, when the impurities on the filter screen 402 are too much and affect the flow rate of water passing through the filter screen 402, a staff member disengages the threaded connection between the connecting shell 301 and the shell 302, so that the filter screen 402 is exposed, and then the impurities on the filter screen 402 are cleaned, or the threaded connection between the fixed block 401 and the filter screen 402 is disengaged, so that the filter screen 402 is replaced.

[0024] Specifically, the protection assembly 5 comprises a spring 501 and a sliding block 502, both the spring 501 and the sliding block 502 are arranged in the water outlet pipe 303, one end of the spring 501 is fixedly connected with the sealed end of the water outlet pipe 303, the sliding block 502 is fixedly connected with the other end of the spring 501, the sliding block 502 abuts against the inner wall of the water outlet pipe 303, and the sliding block 502 blocks the water outlet 304.

[0025] In the embodiment, when the water filtered through the filter screen 402 enters the water outlet pipe 303 from the storage cavity, the arc surface of the sliding block 502 blocks the water outlet 304 in the initial state, the water continuously enters the water outlet pipe 303 at a certain flow rate, when the water contacts the sliding block 502 and pushes the sliding block 502 to move along the inner wall of the water outlet pipe 303, the sliding block 502 moves and extrudes the spring 501, so that the sliding block 502 gradually moves away from the water outlet 304, the water outlet 304 gradually becomes larger, until the sliding block 502 does not block the water outlet 304, when the drip irrigation is completed and the water pump stops working, the flow rate of the water gradually decreases, when the force with which the water pushes the sliding block 502 is smaller than the elastic force of the spring 501, the spring 501 drives the sliding block 502 to rebound along the inner wall of the water outlet pipe 303, so that the sliding block 502 returns to the initial state, the sliding block 502 blocks the water outlet 304 to prevent, when the drip head 3 is not used, impurities, dust and insects outdoors from entering the drip head 3 through the water outlet 304 of the drip head 3, so that the drip head 3 is protected.

[0026] Specifically, each connecting shell 301 is fixedly installed with a support rod 6 inserted into the soil.

[0027] In the embodiment, the support rod 6 is inserted into the soil beside the seedling, so that the drip head 3 is prevented from directly contacting the soil.

[0028] Specifically, the main pipe 1 is provided with a U-shaped rod 7 for fixing the main pipe 1 to the soil.

[0029] In this embodiment, the main pipe 1 is fixed on the soil by the U-shaped rod 7 to prevent the main pipe 1 from being dislocated.
