Description

Technical Field

[0001] The utility model belongs to the field of greenhouse film testing equipment, and in particular relates to a greenhouse film drip performance simulation tester. Background Art

[0002] my country's agricultural plastic film production ranks first in the world, with more than 700,000 tons of greenhouse film used annually, which plays an important role in the growth, yield and income of crops. Agricultural greenhouse film needs to be tested for drip performance, which requires a drip tester. The drip tester is an instrument for testing the high-temperature drip effect of greenhouse film. The shape and modeling of the instrument are single, and it cannot simulate the various greenhouse film usage environments in actual use, resulting in deviations in the experimental results and affecting the accuracy of the results.

[0003] The top of the existing drip performance tester is generally a fixed-angle inclined surface or a plane with a heavy hammer falling on it. The inclined surface or the plane can only simply simulate the commonly used angles or shapes of greenhouses, and cannot restore the various greenhouse shapes during the actual use of the greenhouse film. This is also the reason for the deviation of the experimental results. Utility Model Content

The use of the device can solve the shortcomings of the above-mentioned prior art and achieve the effect of restoring various greenhouse shapes in the actual use process of the greenhouse, such as cold greenhouse, double-film greenhouse, etc., which is closer to the actual situation and can more accurately test the drip performance of the greenhouse film.

[0006] Preferably, the bottom frame includes a bottom transverse frame arranged across the film pressing block; the bottom frame also includes a bottom longitudinal frame arranged vertically across the film pressing block; a bottom female connector is arranged upward at the contact point between the bottom frame and the film pressing block.

[0007] Preferably, the middle frame includes a middle transverse frame and a middle longitudinal frame; middle connecting rods are provided at the places where both ends of the middle transverse frame and the middle longitudinal frame contact with the bottom frame.

[0008] Preferably, the top frame includes a top transverse frame and a top longitudinal frame; top plug-in rods are provided at the places where both ends of the top transverse frame and the top longitudinal frame contact with the middle frame.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. The multi-layer skeleton is used to simulate the real use scenario of the greenhouse film, with high simulation performance and diversified test conditions, which can more accurately measure the dripping effect of the greenhouse film in a variety of different use environments;

[0011] 2. The tester itself has a simple structure and is easy to assemble and disassemble, which is convenient for expanding production and promoting its use on a large scale;
