Description
Technical Field
The invention belongs to the field of tobacco planting equipment, and particularly relates to a mulching film device convenient for ventilation and heat dissipation of tobacco plant roots.
Background
The mulching film mainly utilizes the plastic film with very thin thickness to cover the soil for crop growth, so that the soil can be subjected to heat preservation and fertilizer preservation, and in the prior art, the mulching film mulching cultivation belongs to a very mature crop cultivation technology, but with the large-scale use of the mulching film and the lower recovery rate of the mulching film, the mulching film pollution of a field is gradually aggravated. Especially, the ultra-thin mulching film is used, and the physical strength is insufficient due to the fact that the thickness of the ultra-thin mulching film is too small, so that phenomena such as cracking, ageing, weathering and the like are easy to occur in the growth process of crops, and the ultra-thin mulching film cannot be effectively recycled.
In the prior art, some technical concepts of hard mulching films are proposed, for example, patent documents with publication number of CN205546759U, CN207978541U, CN208783373U and the like, although a covering structure with large thickness and high hardness is provided to realize the repeated utilization of the structure so as to prevent pollution caused by weathering and crushing, the technical scheme is more similar to the miniaturization of a greenhouse structure, the practicality of covering soil as a mulching film is poor, meanwhile, the mulching film also needs to perform hole digging and seedling digging operations, such as strawberries, tobacco plants and the like, and for crops with long growth time and large volume of tobacco, the mulching film needs to be separated from ridge soil in the middle growth stage of the tobacco plants, namely, the mulching film is not needed, and the hard mulching film in the prior art cannot realize the functions.
Meanwhile, when the tobacco plants are transplanted in 4-5 months of the film covering period, the day and night temperature difference of the field is larger, the subfilm soil at the root of the tobacco plants is subjected to stronger illumination in daytime and is heated up rapidly, the temperature is up to more than 50 ℃, the mulching film needs to be torn in time for ventilation and heat dissipation so as to prevent the root of the tobacco plants from being injured, but the heat preservation effect of the mulching film is damaged directly, and tobacco farmers also need to realign and pave the torn mulching film in the evening and cover the torn mulching film with the soil so as to keep the heat preservation effect of the mulching film as much as possible to resist the low temperature at night. The whole operation is labor-consuming and time-consuming, and influences the growth of tobacco plants, so that the growth speed of the tobacco plants is easily reduced, and the development quality of leaves is easily reduced.

Preferably, the soil binding nails are upwards bent.
Preferably, the hard film belt is made of transparent plastic with the thickness of 1mm, and the support plate is made of black PVC material.
The application process of the invention is as follows:
firstly, selecting a corresponding number of support plates according to the length of a tobacco ridge, inserting and matching the assembly clamping strips of the support plates with the assembly clamping grooves of the adjacent support plates, sequentially operating to form support mechanisms, abutting the two support mechanisms against two sides of the tobacco ridge, and keeping the support plates of the two support mechanisms arranged in a pairwise corresponding mode. Finally, the soil binding rod at the bottom of the support plate is bound into the ground, so that the installation of the support mechanism is completed. Because the soil binding nail of the soil binding rod is bent upwards, the resistance of the soil binding rod penetrating into the ground is not overlarge, but the resistance of the soil binding rod during external pulling can be improved, and the connection stability of the support plate and the ground can be ensured. Meanwhile, the supporting mechanism can be firstly formed by mechanical ridging and then arranged, or the supporting mechanism can be firstly arranged and then the soil is filled between the two supporting mechanisms by using the machine to form the tobacco ridge. Because the standardization and refinement requirements of tobacco planting at present, the width and the interval of the tobacco ridges, and the depth, the diameter and the interval of the transplanted tobacco holes have specific parameter requirements, the setting of the supporting mechanism can be completely dependent.
After tobacco seedlings are transplanted into tobacco ridges, two ends of each mulch film unit are placed at the tops of the two corresponding support plates, then a sleeve at one end of each mulch film unit is matched with a draw hook on the corresponding support plate, meanwhile, the draw hook on the other support plate is pushed upwards against the elasticity of the second limiting spring, and then the mulch film unit is tensioned and the sleeve at the other end of each mulch film unit is matched with the draw hook of the corresponding support plate.

And each mulching film unit is matched with the corresponding assembly convex strips and the corresponding assembly grooves, so that a complete mulching film mechanism is formed and the gap between the two support mechanisms is well closed. Finally, after the two ends of the tobacco ridge are covered by the common mulching film in a matched manner, a complete mulching film structure capable of covering tobacco seedlings is formed. It should be noted that the film of the mulching film unit should be disposed at the position corresponding to the tobacco seedling, so that the punching and seedling picking and film uncovering operations of the film are realized after the tobacco seedling grows for a certain time.
When ventilation under the film is needed, the sleeve is rotated, and the first limit spring is in a compressed state at all times, so that the axial pushing acting force of the first limit spring on the sleeve and the pull cylinder enables the pull cylinder to be unable to rotate along with the rotation of the sleeve as much as possible, and meanwhile, the trend of rotation along with the rotation of the sleeve can be effectively prevented due to the fact that the length of the mulching film unit is fixed. In addition, the threads of the two threaded rods are opposite in rotation direction, so that the threaded rods drive the pull cylinders to axially move oppositely, and further drive the two hard film belts to move oppositely, so that gaps between two adjacent mulching film units at the exposed positions are exposed, and ventilation and heat dissipation are realized. When heat preservation is needed, the sleeve is reversely rotated, the mulching film unit is reset and closed, the temperature under the mulching film is kept, and the night low temperature is resisted.
