Heat-preservation overwintering mulch applicator for northern vine crops

Abstract

The invention belongs to the technical field of agricultural machinery and discloses a heat-preservation overwintering mulch applicator for northern vine crops. The mulch applicator comprises a transverse girder and two operation machines, and the two operation machines longitudinally and symmetrically sleeve two ends of the transverse girder. Two sleeves are abreast fixed to the middle of the transverse girder, a left telescopic arm is inserted in the front sleeve, a right telescopic arm is inserted in the rear sleeve, a left hydraulic cylinder is hinged between the front sleeve and the lefttelescopic arm, and a right hydraulic cylinder is hinged between the rear sleeve and the right telescopic arm. Each operation machine is formed by connection of a ground square frame with a longitudinal supporting frame and a film roll support connected to the top of the longitudinal supporting frame. By the sleeves for connection of parts and by adoption of the hydraulic cylinders, vertical and bilateral lifting and telescoping can be realized; aiming at characteristics of the vine crops, vine smoothers are arranged, a pair of film pressing rollers are arranged below the rear of each ground square frame, and a rolled film on each film roll support penetrates a gap between the corresponding film pressing rollers. By the mulch applicator, mulching efficiency and mulch film immobility are greatly improved, labor intensity and production cost are reduced, and the mulch applicator is especially suitable for large-scale mechanical operation.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a thermal insulation and overwintering film covering machine for northern vine crops. Background technique [0002] The winter climate in the north is cold, and the heating period in some areas is as long as 4-5 months. Under such cold climate conditions, some vines need to be covered with plastic film during the wintering period to ensure that they will not be frostbitten and survive the winter safely. When covering plastic film, the most traditional way is to cover the film manually, and then manually press the soil on the plastic film to fix the plastic film. Equipment replaces manpower, which increases convenience and improves efficiency. However, the existing mulching machines still have some defects, especially when vine crops are overwintered and covered with film in the north, due to the growth characteristics of the crops, their branches meander up and do...

AI Technical Summary

Problems solved by technology

However, the existing mulching machines still have some defects, especially when vine crops are overwintered and covered with film in the north, due to the growth characteristics of the crops, their branches meander up and down, left and right, and their fixation is relatively weak when covering them with mulch. Low, before passing through the peritoneum of the laminating machine, it needs to be straightened out manually, which is time-consuming and laborious, and the degree of automation is low
