Description

Technical Field

[0001] This utility model relates to the field of drip irrigation technology, specifically a drip irrigation spacing calibrator for vegetable greenhouses. Background Technology

[0002] Vegetable drip irrigation is a water-saving technology that uses low-pressure pipes and drippers to precisely irrigate the roots of vegetables in a drip-by-drip manner. Its core components include a water tank, valves, water pipes, and drippers. It is often used in conjunction with mulch film and is suitable for arid regions, greenhouses, orchards, and other similar settings, achieving a water utilization rate of up to 95%. This technology allows for simultaneous fertilization, but dripper clogging must be prevented.

[0003] In the current drip irrigation process in vegetable greenhouses, the drip irrigation points are calibrated and positioned using a measuring tape. However, the measuring tape is inefficient, and each time a reading is taken, calculated, and marked, which is cumbersome, time-consuming, and labor-intensive. Based on the shortcomings of existing technology, this utility model designs a drip irrigation spacing calibrator for vegetable greenhouses. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a drip irrigation spacing calibrator for vegetable greenhouses, which has the advantages of rapid adjustment and improved calibration efficiency.

[0005] This utility model provides the following technical solution: a vegetable greenhouse drip irrigation spacing calibrator, including a first metal ruler and a second metal ruler, and a positioning structure fixed to the ends of the first metal ruler and the second metal ruler. The top of the first metal ruler is provided with a first scale, and the top of the second metal ruler is provided with a second scale. The two positioning structures include a fixing block, a side block fixedly installed on one side of the outer surface of the two fixing blocks, a fixing post fixedly installed on the top of the two side blocks, a second sliding groove opened on both sides of the outer surface of the two fixing posts, a positioning pin slidably installed inside the two fixing blocks, two rotating rods fixedly installed on both sides of the outer surface of the two positioning pins, a hinge rod hinged to the end of the two rotating rods, a slider fixedly installed on the lower inner side of the two hinge rods, the two sliders slidably connected to the second sliding groove, and a pressure rod fixedly installed on the upper inner side of the two hinge rods.

[0006] As a preferred embodiment of this utility model, the numbers on the first scale increase sequentially from the left, and the numbers on the second scale increase sequentially from the right to the left.

[0007] As a preferred embodiment of the present invention, the outer surface of the second metal ruler is provided with a first sliding groove on both sides, and a rotating shaft is fixedly installed inside the first metal ruler.

[0008] As a preferred embodiment of this utility model, a roller is rotatably mounted inside the rotating shaft, and the roller is slidably connected to the first sliding groove.

[0009] As a preferred embodiment of this utility model, a mounting bracket is fixedly installed on one side of the outer surface of the first metal ruler, and a threaded rod is installed on the internal thread of the mounting bracket.

[0010] As a preferred embodiment of this utility model, when the end of the threaded rod extends into the first metal ruler, it presses against the first sliding groove to fix it, and a throttle is fixedly installed at the end of the threaded rod.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This vegetable greenhouse drip irrigation spacing calibrator, through a first metal ruler, a second metal ruler, and a positioning structure, calibrates the drip irrigation spacing by pulling the second metal ruler out of the first metal ruler to the required distance and fixing it. The left end of the first metal ruler is then placed at the end of the ridge, and the right-side pressure rod is pressed down. Since the sliders on both sides are slidably connected to the second groove, pressing the pressure rod moves the positioning pin downwards, causing it to embed itself in the soil and anchor the device. The device is then rotated counterclockwise by 30 degrees, and the above actions are repeated to embed the left-side positioning pin in the soil. At this point, the pressure rod at the end of the second metal ruler is pulled upwards to remove the positioning pin from the soil. This process is repeated, and the drip irrigation opening can be confirmed based on the hole created by the positioning pin. This achieves rapid calibration and improved efficiency. Compared to traditional measuring tape positioning, the positioning is sufficiently accurate, ensuring consistent spacing and higher precision. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-5 A vegetable greenhouse drip irrigation spacing calibrator includes a first metal ruler 1 and a second metal ruler 2, as well as a positioning structure 3 fixed to the ends of the first metal ruler 1 and the second metal ruler 2. The top of the first metal ruler 1 is provided with a first scale 101, and the top of the second metal ruler 2 is provided with a second scale 21. The two positioning structures 3 include a fixing block 31, a side block 32 fixedly installed on one side of the outer surface of the two fixing blocks 31, a fixing post 33 fixedly installed on the top of the two side blocks 32, a second sliding groove 34 opened on both sides of the outer surface of the two fixing posts 33, a positioning pin 35 slidably installed inside the two fixing blocks 31, two rotating rods 36 fixedly installed on both sides of the outer surface of the two positioning pins 35, a hinge rod 37 hingedly installed at the end of the two rotating rods 36, a slider 38 fixedly installed on the lower inner side of the two hinge rods 37, the two sliders 38 slidably connected to the second sliding groove 34, and a pressure rod 39 fixedly installed on the upper inner side of the two hinge rods 37.

[0016] Example 1 Please see Figures 1-3 The numbers on the first scale 101 increase sequentially from left to right, and the numbers on the second scale 21 increase sequentially from right to left. A mounting bracket 104 is fixedly installed on one side of the outer surface of the first metal ruler 1, and a threaded rod 105 is threaded into the interior of the mounting bracket 104. When the end of the threaded rod 105 extends into the interior of the first metal ruler 1, it presses against the first sliding groove 22 to fix it in place. A throttle 106 is fixedly installed on the end of the threaded rod 105.

[0017] By sliding the second metal ruler 2 out from inside the first metal ruler 1, the drip irrigation interval is confirmed by adding the first scale 101 to the leaked second scale 21. After confirmation, the threaded rod 105 is rotated and moved inside the mounting bracket 104 by rotating the handle 106, so that it contacts the first slide groove 22 and fixes the second metal ruler 2 inside the first metal ruler 1.

[0018] Example 2 Please see Figures 1-3 The outer surface of the second metal ruler 2 has first grooves 22 on both sides, and a rotating shaft 102 is fixedly installed inside the first metal ruler 1. A roller 103 is rotatably installed inside the rotating shaft 102, and the roller 103 is slidably connected to the first groove 22.

[0019] The roller 103 is slidably connected to the first slide groove 22. When the second metal ruler 2 is pulled, the roller 103 rotates inside the first slide groove 22 as it moves with the second metal ruler 2, thereby improving the smoothness of the second metal ruler 2.

[0020] Working principle: When using a vegetable greenhouse drip irrigation spacing calibrator, firstly, the second metal ruler 2 slides out from inside the first metal ruler 1. When the second metal ruler 2 is pulled, the roller 103 rotates inside the first groove 22 as the second metal ruler 2 moves, improving the smoothness of the second metal ruler 2. The drip irrigation spacing is confirmed by adding the first scale 101 to the leaked second scale 21. After confirmation, the threaded rod 105 is rotated and moved inside the mounting bracket 104 by rotating the handle 106, so that it contacts the first groove 22 and fixes the second metal ruler 2 inside the first metal ruler 1. Then, place the left end of the first metal ruler 1 at the end of the ridge, and then press down the right pressure rod 39. Since the sliders 38 on both sides are slidably connected to the second sliding groove 34, pressing the pressure rod 39 can drive the positioning needle 35 to move downward, thereby making it penetrate into the soil and anchor the device. Then rotate the device counterclockwise 180° and repeat the above actions to penetrate the left positioning needle 35 into the soil. At this time, pull up the pressure rod 39 at the end of the second metal ruler 2 to pull the positioning needle 35 out of the soil. Rotate again and repeat the above operation. In this way, the drip irrigation opening can be confirmed according to the hole made by the positioning needle 35.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
