Abstract

The invention discloses an agricultural film mulching device. The agricultural film mulching device comprises a supporting pipe, convex columns are arranged on the inner walls of the two ends of the supporting pipe, and circular grooves are formed in the outer walls of one ends of the convex columns; connecting columns are fixedly connected to the outer walls of one sides of the convex columns, and circular grooves are formed in the outer walls of one sides of the connecting columns; rotating balls are clamped to the inner walls of the circular grooves, a supporting frame is arranged on the outer walls of one sides of the rotating balls, and a connecting pipe is clamped to the middle section of the supporting frame; the two ends of the supporting frame are rotationally connected to the inner walls of the convex columns through bearings, tightening sleeves are in threaded connection with the outer walls of the connecting columns, and second limiting blocks are arranged on the outer walls of one sides of the tightening sleeves; and the outer walls of the two ends of the supporting pipe are fixedly connected with first limiting blocks. When the agricultural film mulching device is used, a worker can hold the supporting frame with one hand, in the process of moving the whole device, the mulching film rotates with the supporting pipe as the center and is unfolded, at the moment, theworker can cover the edge of the mulching film with the other hand, and therefore laying of the mulching film can be completed by one person.
