Film mulching machine for garlic sprouts

Abstract

The invention provides a film mulching machine for garlic sprouts. The film mulching machine comprises a connecting truss, ploughs, an induced draft fan, a heat preservation film roll, a supporting rod, a linkage frame, a right-angle actuator, baffles, a spline shaft, a hollow concave plate, an air inlet, and a flow guiding groove, a convex plate, a heating plate, auxiliary rollers, linkage rods,earthing wheels and flow guiding teeth. The lower side, from one side to the other side, of the connecting truss is sequentially and fixedly connected with the ploughs, the induced draft fan, the supporting rods, the linkage frame and the right-angle actuator. As the outer edge of an opening of an air inlet is curved, the height difference between the convex plate and the air inlet is 0.3 cm, theconvex plate is located inside the air inlet with respect to the flow guiding groove and the gap between the convex plate and the air inlet is small, when the induced draft fan acts, the pressure of the airflow at the air inlet increases, the airflow under a film is accelerated and the pressure intensity under the film is reduced, so that the film is pressed down by the higher pressure above the film for better contact with the ground to prevent inflation between the film and the ground.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a film covering machine for garlic sprouts. Background technique [0002] Garlic seedlings are young garlic seedlings that have grown to a certain period of time. It grows in the farmland. It has a spicy taste of garlic and is eaten with its tender garlic leaves and leaf sheaths. Garlic sprouts are rich in vitamin C, protein, carotene, thiamine, riboflavin and other nutrients. Its spicy taste mainly comes from the capsaicin it contains, which has the effect of eliminating food accumulation. In addition, eating garlic sprouts can also effectively prevent influenza, enteritis and other diseases caused by environmental pollution; [0003] Garlic seedlings need to be covered with a film when they are planted to achieve the purpose of heat preservation. [0004] Based on the above description, and in combination with the equipment in the prior art, it is found that the existing...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a film covering machine for garlic seedlings to solve the problem that the film covering work is generally done manually, which is time-consuming and laborious, and air will be generated under the film, resulting in low quality of film covering.
