Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to a sowing and film covering device for wheat planting. Background Art

[0002] As the global population continues to rise, the demand for food is growing like a snowball, which undoubtedly puts tremendous pressure on the agricultural production field, prompting it to move towards efficiency and refinement. Among various food crops, wheat, with its wide adaptability and basic status as a staple food, deservedly becomes one of the world's major food crops and plays a pivotal role in the global food supply system. When focusing on the current agricultural production practice, especially the specific links of wheat planting, it is not difficult to find that the traditional sowing and film covering methods are in many difficulties, so it is urgent to design a sowing and film covering device for wheat planting.

[0003] Traditional wheat sowing usually relies on manual sowing or simple sowing equipment. Manual sowing is extremely inefficient and consumes a lot of manpower. It is difficult to ensure uniform distribution of seeds, and uneven density is prone to occur, which directly affects the subsequent growth and development of wheat and leads to uneven yields. Although simple sowing equipment has improved sowing efficiency to a certain extent, it has a single function and cannot accurately control the sowing amount, often resulting in seed waste or partial seedling shortages. In terms of film covering, plastic film was mostly laid manually in the past. This method is not only labor-intensive, but also requires workers to bend over for a long time and is very easy to fatigue, which seriously restricts the progress of planting, especially when planting on a large scale, and cannot meet the requirements of farming time.

The soil is leveled by the screed plate to avoid wrinkles and damage after the film is laid, and the heat preservation, moisture retention and weed suppression functions are fully exerted to create a good soil environment for wheat growth. In addition, the film covering roller is closely connected with the irrigation system composed of the fixed frame, the second bucket, the drainage seat and the driving rod, so that sowing, fertilization, irrigation and film covering can be completed in one stop, shortening the planting cycle and meeting the requirements of farming time. It is particularly suitable for large-scale planting and speeding up the planting process. (3) In the sowing film covering device for wheat planting of the present invention, the auxiliary cutting device composed of the track plate, movable seat, top seat, hinged rod, movable frame and cutting wheel is convenient for timely trimming of the film during film covering, ensuring that the film is laid to an appropriate length, reducing material waste and optimizing the film covering effect. In addition, during film covering, the film is prone to deviation and skew due to its own characteristics, wind force, mechanical pulling, etc. The positioning seat and the correction plate can fix the edges of both sides of the film so that it can be laid according to the preset track, and can adjust the slight deviation of the film in real time to ensure that the film covers the ground evenly with a precise width. In this way, the film can fit the ground closely, give full play to the functions of heat preservation, moisture retention and weed suppression, prevent local soil environment abnormalities caused by film position deviation, and reduce the time and manpower consumed in re-laying and adjusting the film, thereby improving the quality and efficiency of film covering and creating good conditions for the early growth of wheat.

As the input shaft rotates, the meshing transmission of the worm and the worm wheel drives the internal threaded rod 172 to move up and down, thereby making the base 173, the fixing seat 174 and the leveling plate 175 rise and fall together. In the film covering process, the leveling plate 175 can adjust the height in real time according to the actual flatness of the land. The soil is leveled by the leveling plate 175 to avoid wrinkles and damage after the film is laid. In terms of the irrigation process, the No. 2 bucket 21 is used as a water storage container to store the water resources required for irrigation in advance. When sowing and film covering operations are performed simultaneously During the process, the driving rod 222 starts to rotate under the drive of the power system, and the sprocket at the left end thereof is linked with the sprocket at the left end of the second spiral feed column 162 through a chain. As the second spiral feed column 162 rotates, the driving rod 222 also rotates synchronously, thereby driving the three sets of water wheels installed thereon to rotate at high speed. At this time, the water in the second bucket 21 flows into the drainage seat 22 through the drainage pipe 223 under the action of gravity. Under the centrifugal force of the high-speed rotating water wheel, the water is evenly thrown to the irrigation pipe 221, and is accurately sprayed on the land that has just been sown and covered with film through the irrigation pipe 221, providing sufficient moisture for seed germination in time; As the device moves forward, the coating roller 1762 can closely contact and smoothly unfold the plastic film, evenly spread the film on the ground surface, and ensure the continuity and integrity of the coating. The positioning seat 1771 and the correction plate 1772 can fix the edges of the film on both sides so that it can be laid according to the preset track. The slight deviation of the film can be adjusted in real time to ensure that the film covers the ground evenly with precise width. The operator only needs to operate the hinged rod 243, and with the help of the elastic assistance of the coil spring, push the movable frame 244 down to make the cutting wheel 245 contact the film, so as to easily cut off the film and achieve precise trimming. After the coating is completed, as the device continues to move forward, the turning plate 23 can turn up the soil and accurately bury the edge of the film.
