Description

Technical Field

[0001] The invention relates to the technical field of agricultural greenhouses, and in particular to a precision irrigation device for an agricultural grape planting greenhouse. Background Art

[0002] As living standards continue to improve, agricultural production has also been further promoted. In today's agricultural production, greenhouses are one of the indispensable equipment, so that crops can grow off-season. In grape planting greenhouses, grapes can grow off-season, which further increases farmers' income. Irrigation is one of the indispensable links in the process of planting grapes in greenhouses. In the current grape irrigation process, the traditional direct irrigation is changed to pipe laying irrigation, so that pipe laying can be used to achieve drip irrigation of grapes and drip irrigation can also be used to save water.

[0003] Although the existing precision irrigation devices for agricultural grape planting greenhouses can adjust the height and angle of the nozzles at will, after the grape seedlings take root and sprout, in order to save water while ensuring that the seedlings can grow rapidly, the adjustment distance of the nozzles is limited, which can easily lead to uneven soil moisture distribution, excessive moisture in some local areas, and other areas may be too dry, which is not conducive to the maintenance of soil biodiversity, and can cause soil compaction, weaken plant root cell respiration, affect energy supply, and then affect nutrient absorption, thereby affecting the normal growth of grape plants.

[0044] By adopting the above technical solution:

[0045] When in use, when water flows inside the drip irrigation pipe 6, the water in the drip irrigation pipe 6 is driven by gravity and the potential energy generated by the flow to drive the drip irrigation pipe 6 to move up and down, so that the drip irrigation pipe 6 drives the pipe collar 504 to move up and down, and the pipe collar 504 drives the pull rod 509 to move up and down through the connecting block 511, and the pull rod 509 drives the transmission rod 507 to move up and down through the fixing block 510, and the transmission rod 507 is limited by the lifting block 513, so that the transmission rod 507 drives the positioning ball 507 through the lifting block 513. 22 moves up and down, so that the positioning ball 522 drives the slide plate 514 to move along the slide groove of the limit frame 502, and at the same time, the transmission rod 507 rotates around the axis of the positioning ball 522, so that the transmission rod 507 drives the plug 508 to make an arc movement, and the plug 508 drives the flip frame 523 to make an arc movement, and the flip frame 523 drives the mounting plate 525 to make an arc movement, and the mounting plate 525 drives the digging rod 516 to make an arc movement, so as to break the compacted soil and dig the soil at the same time.

[0047] Secondly, refer to Figure 3 , Figure 5 , Figure 6 , Figure 7 , Fig. 9 , Fig.10 and Fig.11 As shown, a liftable locking rod 524 is provided on the top of the flip frame 523, a third spring 506 is provided between the locking rod 524 and the flip frame 523, and a plurality of locking grooves matched with the locking rod 524 are provided on the outer wall of the plug 508.

[0052] By adopting the above technical solution:

[0053] When in use, by rotating the top plate 519, the top plate 519 is matched with the threaded hole, so that the top plate 519 moves up and down along the outer wall of the threaded rod 520, so that the top plate 519 drives the limiting collar 518 to move up and down through the support rod 521, and the limiting collar 518 drives the positioning tube 503 to move up and down, and the positioning tube 503 drives the dustproof frame 505 to move up and down through the buffer rod 515, and the dustproof frame 505 drives the pull rod 509 to move up and down through the fixing block 510, and the pull rod 509 drives the pipe collar 504 to move up and down through the connecting block 511, and the pipe collar 504 drives the drip irrigation pipe 6 to move up and down, so as to facilitate the adjustment of the height of the drip irrigation pipe 6 and prevent the drip irrigation pipe 6 from contacting with moist soil for a long time, which can not only prevent the soil from clogging the nozzle of the drip irrigation pipe 6, but also improve the service life of the drip irrigation pipe 6.

[0055] By adopting the above technical solution:

[0056] When in use, the two second buffer blocks 9 naturally droop and contact the ground due to the gravity on the opposite sides, and the second buffer blocks 9 are protected by the protective cover to prevent the second buffer blocks 9 from being corroded by moist soil, thereby increasing the service life of the second buffer blocks 9. The shaking of the drip irrigation pipe 6 during drip irrigation can also be buffered to prevent the drip irrigation pipe 6 from being damaged due to excessive buffering force, thereby extending the maintenance time interval and reducing the maintenance cost.

[0057] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
