Description

Technical Field

[0001] The utility model relates to the technical field of agricultural film covering machines, in particular to a film surface edge pressing mechanism of an agricultural film covering machine. Background Art

[0002] Agricultural mulching machine is a mechanical equipment used for mulching with film, which aims to increase ground temperature and protect crop growth. This machine lays and seals plastic film on the bed surface or the ground. It is mainly used for mulching cultivation of crops such as vegetables, peanuts, cotton, tobacco, fruits and so on. Mulching with film can not only increase ground temperature, conserve water, soil and fertilizer, but also kill weeds, prevent diseases and insects, prevent drought and waterlogging, inhibit salt and protect seedlings, improve near-ground light and heat conditions, and make products more hygienic and clean. For newly unearthed seedlings, the film has the function of protecting roots and promoting growth. During the use of the agricultural mulching machine, the moving agricultural mulching machine will automatically cover the plastic film on the ground. After the plastic film is laid, the pressing rollers on both sides of the agricultural mulching machine will press over the plastic film, so that the edge of the plastic film fits with the ground. Then the crushed soil will cover the edge of the plastic film, thereby pressing the plastic film on the ground to complete the mulching operation.

[0003] Traditionally, when plastic film is spread on the ground, as the agricultural mulching machine moves, some gas will be pressed at the bottom of the plastic film and cannot be discharged in time. After the plastic film is pressed by the crushed soil, part of the gas will still remain at the bottom of the plastic film, causing the plastic film to bulge and not fit the ground. The air cannot be discharged in time, which will easily affect the growth of crops in the future. In windy weather, the bulging plastic film is more likely to be blown away by the wind, affecting the fit of the plastic film.

[0004] Therefore, it is necessary to provide a new film edge pressing mechanism for an agricultural film covering machine to solve the above technical problems. Utility Model Content

[0005] The purpose of the utility model is to provide a film edge pressing mechanism for an agricultural film laminating machine, which is easy to operate, can timely extract the air at the bottom of the plastic film, and reduce the phenomenon of bulging after the plastic film is pressed.

Rotational connection, a vertical plate 9 is fixedly installed on the top of the horizontal plate 3, an air pump 10 is fixedly installed on the right side of the vertical plate 9, a connecting pipe 11 is fixedly installed on the air inlet of the air pump 10, a mounting pipe 12 is provided on the top of the horizontal plate 3, the bottom end of the connecting pipe 11 is fixedly connected to the mounting pipe 12 and remains connected, both ends of the mounting pipe 12 are threaded with protective sleeves, multiple air holes are provided on the two protective sleeves, and the two protective covers can prevent soil from entering the mounting pipe 12, and two pressing rollers 13 are fixedly installed on the bottom of the horizontal plate 3.

[0023] In order to clean the two pressing rollers 13 and scrape off the broken soil adhering to the pressing rollers 13, and prevent the two pressing rollers 13 from slipping when rotating, in this method, a fixing plate 14 is fixedly installed on the top of the transverse plate 3 by two bolts, and two rectangular blocks 15 are fixedly installed on the bottom of the fixing plate 14. The same threaded rod 16 is rotatably installed between the two rectangular blocks 15, and a handle is fixedly installed at one end of the threaded rod 16. A sliding block 17 is threadedly installed on the threaded rod 16, and a strip plate 18 is fixedly installed on the bottom of the sliding block 17. Two scrapers 19 are fixedly installed on one side of the strip plate 18. The positions of the two scrapers 19 are respectively adapted to the two pressing rollers 13 to ensure that the two scrapers 19 can scrape off the mud on the two pressing rollers 13.

[0024] In order to prevent the installation of the vertical plate 9 from affecting the installation pipe 12 , in this method, a through hole is opened at the bottom of the vertical plate 9 , the through hole is adapted to the installation pipe 12 , and a discharge pipe is fixedly installed on the air outlet of the vacuum pump 10 .

[0025] In order to ensure the stability of the installation of the installation tube 12 , in this embodiment, two U-shaped clamps are fixedly installed on the top of the transverse plate 3 , and the two U-shaped clamps are fixedly connected to the installation tube 12 .

[0026] In order to reserve sufficient space for movement and installation for the two connecting blocks 2, in this method, two rectangular grooves are opened on one side of the transverse plate 3, and a docking round rod 1 is fixedly installed on the inner wall of the two rectangular grooves. The two docking round rods 1 are respectively rotatably connected to the two connecting blocks 2.

[0027] In order to limit the movement tendency of the rectangular block 15 and the range of its movement, in this embodiment, two docking round rods 2 are fixedly installed between the two rectangular blocks 15, and the two docking round rods 2 are both slidably connected to the sliding block 17.

[0028] The working principle of the film edge pressing mechanism of the agricultural film laminating machine provided by the utility model is as follows:

[0029] In this method, the connecting plate 1 can be fixedly connected to the body of the agricultural mulching machine. In the initial state, the output rods of the two push rods 6 are in a retracted state. When the agricultural mulching machine starts to operate, the two push rods 6 are started first, and the output rods of the two push rods 6 will be output outward at the same time. Through the cooperation of the two adapter blocks 2 7 and the two connecting blocks 3 8, the transverse plate 3 is driven to rotate on the two connecting blocks 1 2. The side of the transverse plate 3 close to the fixed plate 14 will gradually rotate downward until the fixed plate 14 is distributed in a horizontal linear manner. At this time, the two pressing rollers 13 are in contact with the ground, and then the two push rods 6 are automatically closed.

[0030] The position of the connecting plate 1 is the forward direction of the agricultural mulching machine. When traveling in this direction, the two ends of the mounting tube 12 will be located in front of the forward direction of the two pressing rollers 13, so that the plastic film will be covered on the ground and will pass over the two ends of the mounting tube 12. Then the vacuum pump 10 will be started, and the vacuum pump 10 will suck in the air under the plastic film through the two ends of the mounting tube 12. The air then flows through the connecting tube 11 and the vacuum pump 10, and is finally discharged to the outside through the exhaust pipe. With the vacuum pump 10 continuously discharging the air, the air under the plastic film will be greatly reduced, so that when the plastic film is subsequently covered on the ground, it will not be easy to bulge due to excessive air.

[0031] During the process of the agricultural mulching machine driving the equipment to move, if there is a lot of dirt stuck on the two pressing rollers 13, it needs to be cleaned in time. During operation, first stop the drive of the agricultural mulching machine, and then rotate the threaded rod 16. During the rotation of the threaded rod 16, the sliding block 17 will gradually move in the direction of the pressing roller 13 due to the restriction of the two docking round rods 2. The sliding block 17 drives the two scrapers 19 through the strip plate 18 until the two scrapers 19 contact the two pressing rollers 13, and then push the equipment to move. The dirt on the two pressing rollers 13 will be scraped off by the two scrapers 19, thereby achieving the cleaning effect.

[0032] Compared with the related art, the film edge pressing mechanism of the agricultural film covering machine provided by the present invention has the following beneficial effects:

[0033] In the present invention, a mounting tube 12 is provided on one side of the two pressing rollers 13, and the two ends of the mounting tube 12 are respectively located in front of the forward direction of the two pressing rollers 13. Then, the vacuum pump 10 is started, and the vacuum pump 10 can suck in the air at the bottom of the plastic film through the mounting tube 12 and discharge it outward, thereby preventing air from gathering at the bottom of the plastic film when the plastic film is covered, avoiding bulging after the plastic film is covered, and allowing the plastic film to better fit the ground. Subsequently, the position of the two scrapers 19 can be adjusted by manually rotating the threaded rod 16, so that the two scrapers 19 are fitted with the two pressing rollers 13, and the two scrapers 19 can be used to scrape off the soil on the two pressing rollers 13, thereby completing the cleaning of the scrapers 19.
