A convenient leachate collection device for agricultural haystack accumulation

Abstract

The invention provides an easy-to-take leachate collecting device for agricultural straw pile stacking. The easy-to-take leachate collecting device comprises valves, leak plates and leak holes, wherein a liquid collecting bag with a drain valve at the bottom is placed on the inner side of a guide rod; the rear side of the guide rod is provided with a limiting block structure for limiting the placed liquid collecting bag. The device is of a circular structure with a circular cavity at the top, and a reasonable support structure is adopted, so that straw placed on a top cavity can form a space with the top cavity. Moreover, the top is provided with a comprehensive structure constructed by a supporting seat and a clamping table to support hard straw and form a higher space. A grid support composed of circular tubes can be built by wood to accommodate soft straw with a water leakage space still being left at the bottom. Moreover, a grid device is provided, so that the structure is firmer,and the problem of generation of harmful leachate due to rainwater leakage after long-time contact direct of original straw piles and the ground is solved.

Description

Technical field[0001]The invention belongs to the technical field of an agricultural haystack leachate collection device, and more specifically, relates to a convenient access type leachate collection device for agricultural haystack accumulation.Background technique[0002]During the process of stacking and landfilling, the compaction, fermentation and other biochemical degradation of garbage, and the seepage of precipitation and groundwater produce a high concentration of organic or inorganic liquid, which we call garbage leachate. It is also called leachate. After agricultural production, the agricultural straws laid by grain crops will be accumulated for a certain period of time, and will be fermented by rain soaked to form leachate. The leachate contains a variety of toxic and harmful inorganic and organic substances. Among them, as many as 99 kinds of organic pollutants have been tested by technology, and 22 kinds have been included in the key control list of China and the Natio...

AI Technical Summary

Problems solved by technology

[0004] Based on the above, the inventors found that the difference from the above-mentioned patent application occasions is that the existing crop straw haystacks are generally temporarily selected storage places. After the haystacks are stored, they are in direct contact with the ground. The extrusion of the formed haystack will make the bottom of the pile more tightly contact with the ground, and the rainwater falling from the top of the pile will be difficult to discharge from the bottom of the pile, resulting in fermentation. With the erosion of rainwater, the leachate formed at the bottom will flow outward. Spill, affect the surrounding environment, and even affect human health
