Machine for laying salt-resisting mulching film under plough layer of coastal saline-alkali land and use method of machine

Abstract

The invention relates to a machine for laying salt-resisting mulching film under a plough layer of coastal saline-alkali land and a use method of the machine. The machine comprises a rack, a film laying device is arranged below the rack and comprises a soil digging inclined surface, the two sides of the top edges of the soil digging inclined surface are fixed to the rack through columns separately, a film laying bottom plate extends backwards at the bottom edge of the soil digging inclined surface in the horizontal direction, and the top edges of the soil digging inclined surface are rotatablyconnected with a film laying shielding plate capable of covering the rear edge of the film laying bottom plate; supporting plates defining the soil digging inclined surface, the film laying bottom plate and the film laying shielding plate into a film laying cavity extend upwards at the two sides of the film laying bottom plate respectively, a film mounting roller, a film pressing roller and a film spreading roller are rotatably connected to the portion, between the supporting plates, in the film laying cavity from front to back in sequence, the film pressing roller is driven by a driving device electrically connected with a controller, and the two ends of the film pressing roller are in transmission connection with the two ends of the film spreading roller through belts respectively. Themachine achieves the integrated operation of soil loosening, sol breaking, film laying and flat raking, the film laying depth and the inclined angle can be adjusted according to actual planning requirements, and the machine is easy to popularize.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a machine for laying salt-resistant plastic film under a plow layer in coastal saline-alkali soil and a method for using the same. Background technique [0002] my country's coastal saline-alkali land has a large area, serious salinization, and wide distribution. It is an important reserve land resource. The improvement and development of coastal saline-alkali land has important practical significance and practical value for solving the contradiction between man and land in my country and promoting regional economic development. [0003] The 201610656187.X invention patent application discloses a saline-alkali soil partition film-laying machine and its use method. The 201620866499.9 utility model patent application discloses a saline-alkali soil partition film-laying machine. The devices described in the above two patents include two film-laying machines. The group...

[0003] The 201610656187.X invention patent application discloses a saline-alkali soil partition film-laying machine and its use method. The 201620866499.9 utility model patent application discloses a saline-alkali soil partition film-laying machine. The devices described in the above two patents include two film-laying machines. The group, which separates the soil, is divided into three layers. The upper layer is the improved planting layer, the middle layer is the interlayer, and the lower layer is the isolated layer. The depth of filming is determined according to the planned planting crops; Yes, the saline-alkali soil layer is complex, hardened, and the resistance is extremely high. It is impossible to guarantee the normal cutting of the soil layer, and the scope of application is small; its depth is manually disassembled and adjusted through the adjustment hole, and automatic adjustment of the depth and inclination angle cannot be realized; the film is output by the counter roller The film laying group cannot ensure that the film can be flattened and laid normally when outputting the film; in the operation steps, an excavator must be used to dig trenches at the head of the ground to enter the soil, and the integration of deep loosening and crushing of soil and film laying and raking cannot be automatically completed
