Description
Technical Field
The invention belongs to the field of film laminating machines, and particularly relates to a film laminating machine for planting lotus seedpod.
Background
At present, the plastic film mulching is one of key technologies widely applied in the field of cultivation in China, achieves the effects of early maturing, yield increasing and quality improving of crops in the growth period through the effects of supplementing accumulated soil temperature, improving soil moisture content change and the like, and generates serious white pollution while generating a white revolution. The Polyethylene (PE) plastic film belongs to a high molecular compound and is extremely difficult to degrade, and the degradation period of the PE plastic film is as long as 200-300 years. The broken residual films used in successive years are accumulated on a soil plough layer year by year, pollute the soil environment, cause the quality reduction of cultivated land, influence the crop yield and quality, and finally cause the unsustainable agricultural production.
Therefore, in order to continuously ensure the soil warming and soil moisture preservation effects caused by plastic film coverage, the replacement of the existing common PE film by the biodegradable mulching film is a future development trend. At present, biodegradable mulching films are all laid through a film laying machine, the related research make internal disorder or usurp of the film laying machine is quite mature, but the structure is similar approximately, and other operation processes are completed while the biodegradable mulching films are assembled with different agricultural machines for laying the films. However, from the test situation of the biodegradable mulching film, the existing film laying machine for laying the biodegradable film has great influence on the degradation speed of the biodegradable film, so that the biodegradable film is torn too early, and the expected coverage effect cannot be achieved. The existing film spreading machine mainly depends on pulling force to pull down a film belt from a film roll and spread the film belt in the field, and when the film roll is cut, the film layers on the two sides of the film roll are bonded, so that the film is pulled down from the film roll, and when the film is in contact with a bonding point on the film, the film can be subjected to larger pulling force, and tensile stress is generated inside the film.
The reason that the internal tensile stress of the film paved by the existing film paving machine is large mainly lies in that: when the mulching film is uncovered, the mulching film is always in a stretching state, and a large tensile stress exists in the mulching film. Particularly, the biological film is used for crops such as lotus flower white which need to be coated with a film in a short period, and the biological film is required to be degraded quickly, so that the thickness of the used biological film is less than 0.005 mm. Therefore, the development of equipment with small tension applied to the biodegradable mulching film during mulching becomes an urgent need for the current mulching operation of lotus white planting mulching film.
Disclosure of Invention
The invention aims to provide a film laminating machine for planting lotus seeds, which aims to solve the problems that a film is in a stretching state when the film is uncovered and a large tensile stress exists inside the film.
In order to achieve the purpose, the basic scheme of the invention provides a film laminating machine for planting lotus seedpod, which comprises a film uncovering and fertilizing device and a mulching film fixing device, wherein the film uncovering and fertilizing device comprises a rack, a travelling wheel, a film uncovering cam for uncovering a mulching film, a film feeding roller, a liquid outlet hole and a liquid storage box, the travelling wheel is rotatably connected to the rack, the film uncovering cam is fixed at the rotating center of the travelling wheel, the film feeding roller is rotatably connected to the rack, the liquid outlet holes are uniformly distributed at the large-diameter end of the film uncovering cam, the liquid storage box is fixed on the rack, the liquid storage box is positioned above the cam, and the bottom of the; the mulching film fixing device comprises a power cylinder, a piston rod, a vertically downward retracting clamping cylinder, a retracting clamping block, a retracting clamping hole for closing the clamping rod, a vertical fixing rod and two clamping rods, wherein the power cylinder is fixed on the frame, the film uncovering cam can abut against the piston rod of the power cylinder when rotating, the retracting clamping cylinder is fixed on the frame, a rodless cavity of the retracting clamping cylinder is communicated with a rodless cavity of the power cylinder, the retracting clamping block is fixed on the piston rod of the retracting clamping cylinder, the retracting clamping hole is located on the retracting clamping block, the top of the fixing rod is fixed on the frame, the fixing rod is located in the retracting clamping hole, and the two clamping rods are hinged to the bottom of the fixing rod.
The principle of the basic scheme is as follows: place this device on bar soil, promote this device. The travelling wheel starts to rotate, and the travelling wheel drives the film uncovering cam to rotate when rotating. Liquid fertilizer in the liquid storage tank above the film uncovering cam flows into the film uncovering cam under the action of gravity, and when the film uncovering cam rotates, the fertilizer flows out of the liquid outlet hole in the film uncovering cam and is attached to the surface of the cam. When the cam is connected with the mulching film, the fertilizer attached to the film uncovering cam has a certain friction reducing effect, and when the mulching film is excessively pulled by the film uncovering cam, the mulching film and the film uncovering cam can slide relatively, so that the mulching film is prevented from being pulled and cracked in the film uncovering process, and meanwhile, the mulching film is prevented from being always in a pulling-up state in the film uncovering process, and a large tensile stress is caused in the mulching film. When the mulching film is uncovered, the fertilizer is attached to the mulching film by the film uncovering cam, and the fertilizing work before the mulching film is simultaneously finished in the film covering process. And because the fertilizer is smeared when in contact, the fertilizer on the surface of the mulching film is evenly smeared, even the fertilizer is evenly applied.
In addition, when the film uncovering cam rotates, the piston rod of the power cylinder is pushed to move. Because the rodless cavity of the clamping cylinder is communicated with the rodless cavity of the power cylinder, when the piston rod of the power cylinder moves, the piston rod of the clamping cylinder extends out, and the clamping block is pushed downwards. And in the process that the clamping blocks move downwards, the two clamping rods swing inwards. In the process that the two clamping blocks swing inwards, the two sides of the mulching film are clamped into the two sides of the strip-shaped soil, and the mulching film is fixed.
The beneficial effect of this basic scheme lies in: 1. the device can generate relative sliding between the film uncovering cam and the mulching film in the film uncovering process, so that the mulching film is prevented from being broken due to overlarge tension in the film uncovering process, meanwhile, the phenomenon that large tensile stress exists in the mulching film is avoided, the fertilization work before the film is covered is completed in the film uncovering process, and the labor cost of independent fertilization is saved. Secondly, in the process of uncovering the mulching film, the action of fixing the mulching film is also finished, and the labor cost of independently fixing the mulching film is further saved.
2. The device has simple structure and low manufacturing cost.
The first optimization scheme is as follows: the power cylinder is characterized by further comprising a return spring, wherein one end of the return spring is fixed on the power cylinder, and the other end of the return spring is fixed on a piston of the power cylinder. The arrangement of the return spring enables the clamping blocks to ascend.
And the second optimization scheme is as follows: the clamping device further comprises an opening spring, and two ends of the opening spring are respectively fixed on the two clamping rods. The opening and closing of the two clamping rods are realized by the cooperation of the opening and clamping spring and the return spring.
And the optimization scheme is three: the bottom surface of the liquid storage tank and the rotation center of the film uncovering cam are positioned on the same horizontal plane. The liquid storage tank is in same horizontal plane with taking off the membrane cam, makes liquid fertilizer follow and goes out liquid hole slow outflow to make smearing that fertilizer can be even on the plastic film, avoid the too much fertilizer of adhesion on the plastic film, cause the waste.
And the optimization scheme is four: the bottom of the clamping rod is rotatably connected with a film clamping disc. The arrangement of the film clamping disc is convenient for moving and clamping the mulching film into the strip-shaped soil.
