Description

Technical field [0001] The invention relates to the field of selenium sand melon film spreading devices, in particular to a height adjustable film spreading device for selenium sand melon film spreading machines. Background technique [0002] Selenium sand melon is a big watermelon that grows from cracks in the stone. The rock fragments, mainly Carboniferous, which have been weathered and washed by mountain torrents and deposited in the ravines, are pulled and laid on the limestone soil with a thickness of 10-15 cm, which can increase the ground temperature, store water, and preserve moisture. The sand and gravel contain trace elements such as zinc and selenium necessary for the human body, which provide unique natural conditions for the accumulation of large amounts of natural glucose, vitamins, amino acids and various trace elements. [0003] At present, the selenium sand melon needs to use a film spreading device in the process of planting, which is used to spread a layer of fi...

AI Technical Summary

Problems solved by technology

Known film laying machine is generally drawn by power locomotive, as the patent announcement number is: a kind of film laying machine disclosed by CN203167724U, but in the prior art, when selenium sandal melon is laying film, due to the reason of rock debris topography , the height of the film-laying device on the film-laying machine cannot be adjusted according to people's needs. Even if the height of some film-laying devices can be adjusted, it is not stable after adjustment, which is not conducive to people's normal use. For this reason, we provide a Height-adjustable film laying device for selenium sandmelon film laying machine
