Description

Technical Field

[0001] The invention relates to the technical field of flue-cured tobacco planting tools, and in particular to a film-breaking, film-pressing and plant-enclosing device. Background Art

[0002] The promotion of well-cellar transplanting technology has gradually become the mainstream technology for flue-cured tobacco transplanting. The two most important links in the well-cellar transplanting technology are film breaking and soiling. At present, film breaking and soiling require different tools respectively. This leads to repeated operations in the actual application process, delaying the growth of tobacco seedlings and increasing the labor cost of tobacco leaf production.

[0003] Therefore, there is an urgent need for an integrated device for breaking the film and adding soil to tobacco seedlings, which can solve the problem that different tools are needed to be used for breaking the film and adding soil to tobacco seedlings, resulting in low operating efficiency and excessively high labor costs.

[0004] In the patent document with the announcement number CN214676858U, an integrated device for breaking the film and cultivating the soil of tobacco seedlings is disclosed, which is characterized by comprising a first connecting rod and a second connecting rod arranged crosswise, the middle part of the first connecting rod and the middle part of the second connecting rod are hingedly arranged, the lower end of the first connecting rod is connected to a first film-breaking cylinder, the lower end of the second connecting rod is connected to a second film-breaking cylinder, and the first film-breaking cylinder and the second film-breaking cylinder are combined to form a cylindrical structure.

[0005] The functions of this device are limited to breaking the film and adding soil. After breaking the film and adding soil, the soil will be pushed around the tobacco seedlings and there will be a certain gap between the broken film on both sides and the soil. At this time, wind may cause further tearing of the film, reducing the thermal insulation effect of the film. There is no film pressing function, and it is necessary to manually fill the gap between the soil and the film or press the film on both sides with soil.

[0006] In summary, the applicant has proposed a membrane-breaking, membrane-pressing and plant-enclosing device. Summary of the invention

[0007] Aiming at the problem that the existing film breaking and filling device in the prior art has no film pressing function and cannot prevent wind from blowing in from the film opening and causing the ground film to tear, a film breaking and pressing film surrounding device that solves the above problem is proposed.

[0008] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows:

[0009] The cam-shaped member is connected to the bottom surface of the cam-shaped member, and the cam-shaped member is connected to the bottom surface of the cam-shaped member by the spring, and the cam-shaped member is connected to the bottom surface of the cam-shaped member by the spring.

[0010] By setting a first soil-pushing piece and a second soil-pushing piece, the first soil-pushing piece and the second soil-pushing piece are connected through a pull rope and the top of the first connecting rod and the second connecting rod. When we open the first connecting rod and the second connecting rod to the width we need, the soil-pushing piece and the film-breaking cylinder on the same side are close together. At this time, we insert the film-breaking cylinder into the ground, and then we retract the first connecting rod and the second connecting rod to surround the tobacco plant. The film-breaking cylinder surrounds the tobacco plant with the soil in the film-breaking cylinder. At this time, the distance between the top of the connecting rod and the middle part of the soil-pushing piece on the same side will become longer, while the length of the pull rope remains unchanged, which will drive the soil-pushing piece to flip outward and upward around the hinged position. The upward flipping of the soil-pushing piece will drive the soil outside the soil-pushing piece to flip outward, filling the gap between the soil and the ground film or turning the soil onto the ground film to press the ground film, effectively preventing the wind from blowing into the ground film from the film mouth to further tear the ground film, resulting in reduced thermal insulation effect inside the ground film.

[0011] It is further defined that a return torsion spring is passed through the hinge shaft of the first soil-expelling piece and the second soil-expelling piece, one end of the return torsion spring is located on the outer side surface of the first soil-expelling piece and the second soil-expelling piece, and the other end is located on the surface of the first connecting rod and the second connecting rod. When there is no external force, the angles of the two end ends of the return torsion spring are the same as the angles of the first connecting rod and the first film-breaking cylinder, and the same applies to the other side. Arranging the return torsion spring at the hinge position of the soil-expelling piece can enable the soil-expelling piece to be tightly attached to the film-breaking cylinder on the same side due to the action of the return torsion spring when the first connecting rod and the second connecting rod are opened, thereby reducing the resistance when we insert it into the soil at this time, making it easier and more convenient to use.

[0012] It is further defined that a bottom pull ring is provided at the middle position of the outer surface of the first soil-moving piece and the second soil-moving piece, a top pull ring is provided at the top of the first connecting rod and the second connecting rod, and the two ends of the pull rope on one side are respectively connected to the bottom pull ring and the top pull ring on the same side; by setting the bottom pull ring and the top pull ring, the connection of the pull rope can be more convenient and the connection is simpler.

[0013] It is further defined that the bottom of the first membrane-breaking cylinder and the bottom of the second membrane-breaking cylinder are both provided with membrane-breaking teeth; and providing the membrane-breaking teeth at the bottom of the membrane-breaking cylinder can achieve a better membrane-breaking effect.

[0014] It is further defined that handles are laterally provided on the tops of the first connecting rod and the second connecting rod; providing the handles can make it more convenient and labor-saving for us to use.

[0015] Compared with the prior art, the beneficial effect of the present invention is that by arranging the soil-moving pieces, the soil on both sides is pushed to press the film while we are breaking the film to surround the plants, which can effectively prevent the wind from blowing in from the film opening and tearing the film, thereby reducing the thermal insulation effect of the film. The present invention has a simple structure and is easy to manufacture. BRIEF DESCRIPTION OF THE DRAWINGS
