the pressing mechanism 5 includes an inclined clip 51 attached to the pressing guide 45, and one end of the inclined clip 51 away from the pressing guide 45 presses against the surface of the cover film and can push the cover film into the groove.
The invention can realize the pressing of the tail end of the cover film through the pressing guide frame 45 and the inclined clamp 51, so that the tail end of the cover film can still be in an open and tight state after being separated from the winding drum 2; then, when the cover film is discharged to the lowering surface, the overpressure pasting guide frame 45 is directly connected to push the side edge of the cover film to be clung to the field, meanwhile, a groove is cut on the field, and then the cover film discharged from the overpressure pasting guide frame 45 is pressed through the inclined clamp 51 to push the cover film to be clamped into the groove, so that the probability of looseness of the tail end of the cover film is reduced.
Compared with the prior art, the invention can reduce the probability that the large-size cover film loosens immediately after being separated from the winding drum 2, so that the cover film can be always clung to the field to cover and shield the seedlings in the field.
Further, in order to solve the problem that the cover film is bent to the center at two sides due to the larger tightening force at two ends, it is preferable that the clamping plate 31 comprises a clamping plate 311 connected with the traction frame 1, two shaping clamping columns 32 are respectively connected at two ends of the clamping plate 311, the clamping plate 311 is provided with a carrying plate 312 at one side close to the field, and the clamping plate 311 and the carrying plate 312 are arranged between the clamping plate 311 and the carrying plate 312 through cavities;

After the cover film is pulled out of the winding drum 2, the cover film is directly clamped between the clamping plate 311 and the pressure loading plate 312, meanwhile, two sides of the guide cover film are respectively clamped in a clamping frame 321 correspondingly, at the moment, the pressing ring sleeve 325 on the rotating sleeve 323 can press the side edges of the cover film, when the cover film is pulled normally, the center of the cover film slides between the clamping plate 311 and the pressure loading plate 312, the two sides of the cover film can pull the pressing ring sleeve 325 and the rotating sleeve 323 to rotate around the side wall of the connecting shaft 322, and once the side surface of the cover film is stressed (for example, the phenomenon 1 that the cover film is pulled by external force to incline, the phenomenon mainly occurs due to dislocation of the pulling device, the cover film which is fixed at the moment, the two sides of the cover film are not fixed are pulled to bend and fold, the phenomenon 2 that the tightening force of the cover film is too high, the two sides of the cover film are bent towards the center, at the moment, the side edges of the cover film can pull the pressing ring sleeve 325 and the rotating sleeve 323 slide along the side wall of the connecting shaft 322.
The sliding rotating sleeve 323 then presses against the restraining spring 324 so that the force applied to the rotating sleeve 323 by the cover film is removed, thus greatly reducing the problem of bending of both sides of the cover film.
Further, in order to solve the problem that the end of the cover film cannot be well controlled due to the fact that the existing knife is used for cutting the cover film, so that the cover film is easily separated from the film covering mechanism and is loosened, it is preferable that a pre-breaking bar 33 connected with a pressure loading plate 312 is arranged in the cavity, and a plurality of punching column knives 331 are arranged on the surface of the pre-breaking bar 33 at equal intervals;

In this embodiment, the pressing plate 311 and the pressure-bearing plate 312 may have rubber blocks, so that the cover film may not be tightly attached to the punching column knife 331 (i.e. the punching column knife 331 is hidden by the rubber blocks, and only the punching column knife 331 protrudes when the pressing plate 311 and the pressure-bearing plate 312 are close to each other), so as to avoid the punching column knife 331 from scraping the cover film.
In this embodiment, the mode of cutting the blade is converted into the mode of pulling the blade away after multi-point punching (the mode is similar to the mode of cutting a plurality of holes on the same straight line on the surface of paper in the prior art, so that the paper is more convenient to cut), and the separation time of the tail end of the cover film is controllable.
When it is desired to determine the end position of the currently pulled-out cover film, the clamping frames 321 clamping both sides of the cover film are directly driven by an external driving device (an optional electric push rod or a pneumatic seat 412 which is proposed below) to deflect towards the field at the same time, namely, deflect downwards at the same time (the clamping frames 321 are rotationally connected with the clamping plates 311) from the view of fig. 2, the specific structure of the clamping frames 321 is that, referring to fig. 3, when two clamping frames 321 deflect downwards at the same time, the clamping plates 311 push the ejector 326 to move towards the direction of the pressure-bearing plate 312, at the moment, the position of the pressure-bearing plate 312 is pushed up by the ejector 326 and gradually clings to the clamping plates 311, and when the ejector 326 is pushed, the end part slides along the sliding limiting groove 327.
The sliding limiting groove 327 may be formed by two parts with an L-shaped structure, and the end of the sliding limiting groove 327 is also provided with a blocking block, so that the ejector 326 can normally jack up the pressure-bearing plate 312, and the ejector 326 is not offset and misplacement at certain time, the specific connection manner of the ejector 326 and the clamping frame 321 as well as the sliding limiting groove 327 can refer to fig. 3, and the ejector 326 may also be provided as an elastic sheet, so that the ejector 326 can be normally bent and reset.
When the ejector 326 is tightly attached to the clamping plate 311, the punching column knife 331 presses the surface of the cover film to press the surface of the cover film out of the hole, and the clamping frame 321 also carries the cover film to tightly attach to the punching column knife 331 on the inclined strip 332 to complete the punching operation.
Further, in order to facilitate the cover film to be pulled apart rapidly at the punching position, it is preferable that the axis of the adjusting column 43 located at the center of the fixing strip 41 is provided with a gas guide channel 411, one side of the fixing strip 41 away from the traction frame 1 is provided with a pneumatic seat 412 (corresponding to an air extraction and inflation integrated machine and being operated by an external power supply) connected with the traction frame 1, one side of the pneumatic seat 412 is provided with a telescopic gas column 413 (corresponding to a pneumatic push rod) with a movable end connected with the clamping frame 321, the other side of the pneumatic seat 412 is provided with a communication column 414, and the communication column 414 is communicated with the gas guide channel 411;

In order to enable the cover film punching position to be pulled open more quickly, air is directly injected into the air guide channel 411 through the air seat 412 (at the moment, the air seat 412 can also inject air into the telescopic air column 413, or not, the specific operation is only to install an electric valve, the movable end can be extended to enable the clamping frame 321 to deflect after air is injected into the telescopic air column 413), then the pressure in the air guide channel 411 is increased so as to push the lifting column 415 to descend, then the descending lifting column 415 can be pressed to retract into the stop spring 416 to facilitate subsequent resetting, and meanwhile, the descending lifting column 415 can push the negative pressing bar 417 to move, so that the auxiliary pressing bar 418 is pressed between adjacent through holes and presses out the pressing mark (the descending time of the auxiliary pressing bar 418 can be observed through an infrared detection mechanism or directly through human eyes).

The arc groove 421 is provided to prevent the seedling from being crushed by the guide half cover 42 when the cover film is covered on the seedling, and the inclined pressing ring 422 is provided to prevent the cover film from moving widely, so that the cover film is lifted up due to a higher seedling, and the cover film is displaced, and if the inclined pressing ring 422 is not present, the phenomenon of bending and folding in the guide half cover 42 is very easy to occur (the central region of the cover film is relaxed due to a larger lifting amount of the seedling).
Further, in order to solve the problem that the sapling lifts up the cover film more so that the cover film is separated from the groove, it is preferable that the pressing guide frame 45 comprises an inclined clamping block 451 connected with the end of the adjusting column 43, a groove cutting strip 452 is arranged on one side surface of the inclined clamping block 451 away from the adjusting column 43, and a film storage groove 453 is formed in the position of the inner wall of the inclined clamping block 451 corresponding to the groove cutting strip 452;
