The present invention relates to a vinyl sheet covering device which has vinyl sheet covering units and covers a ridge of a field with a vinyl sheet while being towed by a towing vehicle. The vinyl sheet covering units (200, 300, 400, 500) comprises: a vinyl sheet holding unit (10) which has one end portion, fixated to a main frame (100) or a sub-frame (110), and the other end portion, extended on a rear side of the main frame (100) or the sub-frame (110) and holds a vinyl sheet roll; soil discharge units (20A, 20B) which are installed to be symmetrical to each other on the main frame (100) or the sub-frame (110); elastic supports (30A, 30B) which is installed on the main frame (100) or the sub-frame (110) and is installed on a rear side of the vinyl sheet holding unit (10); pressing units (40A, 40B) which are installed to be symmetrical to each other on the elastic supports (30A, 30B) and press the vinyl sheet unwound from the vinyl sheet roll; and soil covering units (50A, 50B) which are located on a rear side of the pressing units (40A, 40B), supply soil to an upper side of the vinyl sheet, pressed by the pressing units (40A, 40B), and covers the vinyl sheet. The soil covering units (50A, 50B) comprise a soil covering wheel (55) and a soil covering blade (57) installed on the inside of the soil covering wheel (55) and rotated by a hydraulic motor (58). The vinyl sheet covering device has significantly increased soil discharging performance and thus can more tightly fixate the vinyl sheet on a ridge of a field.COPYRIGHT KIPO 2017본 발명은 견인 차량에 의해 견인되면서 비닐피복부가 구비되어 밭두둑에 비닐을 피복하는 비닐피복기에 관한 것으로, 비닐피복부(200, 300, 400, 500)는 각각, 일단은 메인프레임(100) 또는 보조프레임(110)에 고정되고, 타단은 메인프레임(100) 또는 보조프레임(110)의 후방 쪽으로 연장되면서 비닐롤이 거치되는 비닐거치대(10)와; 메인프레임(100) 또는 보조프레임(110)에 서로 대칭을 이루면서 설치되는 배토부(20A, 20B)와; 메인프레임(100) 또는 보조프레임(110)에 설치되면서 비닐거치대(10)의 후방 쪽에 설치되는 탄성지지대(30A, 30B)와; 탄성지지대(30A, 30B)에 각각 서로 대칭을 이루도록 설치되어 비닐롤에서 풀린 비닐을 누르는 압지부(40A, 40B)와; 압지부(40A, 40B)의 후방 쪽에 위치하여 압지부(40A, 40B)에 의해 눌러진
