Description

Technical Field

[0001] The invention relates to the technical field of drip irrigation tape detection equipment, and in particular to a drip irrigation tape production sampling inspection device. Background Art

[0002] Drip irrigation tape is a tubular product made of plastic materials such as polyethylene (PE). It has a water outlet inside or on the side, which is used to drip liquids such as water, medicine, and fertilizer evenly and slowly into the soil near the roots of crops. This irrigation method has the advantages of saving water and fertilizer, reducing labor intensity, and increasing crop yield and quality. It has been widely used in modern agriculture. Therefore, the physical properties of the drip irrigation tape directly affect its irrigation effect and crop growth.

[0003] Physical property testing of drip irrigation tape is an important measure to ensure its stable quality and meet market demand. Through testing, quality problems in the production process can be discovered in time and corresponding improvement measures can be taken. The physical properties of drip irrigation tape, such as tensile strength, wear resistance, aging resistance, etc., directly affect its irrigation effect. High-quality drip irrigation tape can ensure uniform distribution of irrigation water and improve irrigation efficiency.

[0032] In an optional implementation manner of the embodiment of the present invention, as Fig.11 As shown, the bottom of the friction frame 28 is made of a rough frosted material.

[0033] Working principle: When the present invention is used, firstly, a portion of the drip irrigation tape to be sampled is cut off, and then the two ends of the cut drip irrigation tape are inserted between the lower clamping plate 14 and the upper clamping plate 15, and then the electric cylinder I18 is started to drive the extrusion block 17 to slide, and the inclined surface on the extrusion block 17 squeezes the upper clamping plate 15, so that the upper clamping plate 15 slides downward, thereby clamping the drip irrigation tape; The next step is to measure the tensile performance. The hydraulic cylinder Ⅰ5 is started to drive the slider Ⅰ4 to slide inward. The slider Ⅰ4 drives the slider Ⅱ7 to slide to both sides through the connecting rod Ⅰ6, so that the drip irrigation belt is stretched. When the drip irrigation belt breaks, it stops and records the data. This is the case of measuring uniform tension. Of course, the tensile performance under the condition of force offset can also be measured. Specifically, when the drip irrigation belt is clamped, the stepper motor Ⅰ11 is started to drive the worm 10 to rotate, thereby driving the transmission assembly 9 to rotate. The gears on the transmission assembly 9 drive the sliders Ⅲ8 on both sides to slide in different directions, thereby driving the lower clamping plate 14 to rotate through the connecting rod Ⅱ12, so that the clamped drip irrigation belt will be offset. When pulling again, the force point on the drip irrigation belt will change. The degree of change depends on the angle of offset. In this way, the tensile performance under the condition of force offset can be measured by stretching until the breaking position. The device can also measure the anti-friction performance of the drip irrigation belt. Similarly, after the drip irrigation belt is fixed between the lower clamping plate 14 and the upper clamping plate 15, the hydraulic cylinder II 24 is started to drive the upper bracket 20 to slide downward, so that the friction frame 28 contacts the drip irrigation belt, and the spring II 29 is compressed to generate a downward force. The size of the force can be adjusted by the electric cylinder II 26 to drive the gasket 27 to slide up and down, so that the compression of the spring changes, thereby changing the elastic force, so that the anti-friction performance under different forces can be measured. After preparation, the stepper motor II 22 is started to drive the screw rod 21 to rotate, thereby driving the slider IV 25 to reciprocate, so that the friction frame 28 rubs back and forth on the drip irrigation belt until the friction breaks, and the data is recorded. In addition to measuring conventional data, the measurement of the device can also measure data under different stress environments, which has stronger practical significance.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is defined by the appended claims and their equivalents.
