Description

Technical Field

[0001] This utility model relates to the field of agricultural mulching machine technology, specifically to a mulching mechanism for an agricultural mulching machine. Background Technology

[0002] Agricultural mulching machines are mechanical devices used for mulching crops with plastic film. The aim is to increase soil temperature and protect crop growth. These machines lay and seal plastic film on raised beds or the ground, primarily for mulching cultivation of vegetables, peanuts, cotton, tobacco, melons, and other crops. Mulching not only increases soil temperature, retains water, soil, and fertilizer, but also controls weeds, prevents pests and diseases, resists drought and flooding, suppresses salinity, protects seedlings, improves near-surface light and heat conditions, and makes crops more hygienic and clean. For newly emerged seedlings, the mulch film helps protect roots and promotes growth.

[0003] When plastic film is laid on the ground, some gas is trapped at the bottom. After the film is pressed down by the soil, the gas remains at the bottom, causing the film to bulge and fail to adhere to the ground. This can affect the growth of subsequent crops. Plastic film that does not adhere well to the ground is also easily blown away in windy weather. To address this, we propose a film-laying mechanism for an agricultural film-laying machine. Utility Model Content

[0006] Preferably, the inner groove is provided with multiple compression springs. One end of the compression spring is fixedly connected to the inner wall of the inner groove, and the other end of the compression spring is fixedly connected to one side of the sliding rod. Through the cooperation of the compression spring, the connecting block, and the sliding rod, when the arc-shaped block rotates and presses the film onto the ground, the pressure pushes the arc-shaped block, the sliding block, and the sliding rod to slide into the inner groove, compressing the compression spring. This expels the air under the film through the pressing force. When the arc-shaped block rotates to another direction, the compression spring rebounds, thereby pushing the sliding rod, the sliding block, and the arc-shaped block to reset.

[0007] Preferably, a crossbar is fixedly connected between the two rotating rods, and two corresponding connecting rods are fixedly connected to the outer side of the crossbar. A first connecting shaft is fixedly connected between the two connecting rods, and a guide roller is rotatably connected to the outer side of the first connecting shaft. The guide roller can guide the film, thereby facilitating the pressing of the film onto the ground.

[0008] Preferably, the mounting frame has two corresponding rotating seats rotatably connected inside via a rotating shaft. The mounting frame has an insertion groove inside, and the rotating seats have a first retaining groove inside. A central shaft is inserted into the first retaining groove, and an unwinding roller is sleeved on the outside of the central shaft. Two corresponding limiting rods are fixedly connected inside both the unwinding roller and the rotating seats. The central shaft has two corresponding limiting grooves inside, and the limiting rods are inserted into the limiting grooves. An insertion block is inserted into the insertion groove, and a film is provided on the outside of the unwinding roller. Through the mutual cooperation of the insertion groove, the first retaining groove, the central shaft, the limiting groove, the insertion block, and the limiting rods, it is convenient to replace the unwinding roller and the film.

[0009] Preferably, an electromechanical box is fixedly installed inside the mounting bracket, and a second servo motor is fixedly installed inside the electromechanical box. The output end of the second servo motor is fixedly connected to one of the rotating seats through a coupling.

[0010] Preferably, a driven gear is fixedly connected to the outer side of the first drive shaft, and a second drive shaft is rotatably connected to the inside of the mounting bracket via bearings. A driving gear is fixedly connected to the outer side of the second drive shaft. The driven gear and the driving gear mesh with each other. An electromechanical box is installed inside the mounting bracket, and a first servo motor is fixedly installed inside the electromechanical box. The output end of the first servo motor is fixedly connected to the second drive shaft via a coupling.

[0011] Preferably, an electromechanical box is provided on the outer side of one of the rotating rods, and a drive motor is fixedly installed inside the electromechanical box. The output end of the drive motor is fixedly connected to the first rotating shaft through a coupling.

[0012] This utility model provides a film covering mechanism for an agricultural film covering machine, which has the following beneficial effects: 1. The mulching mechanism of this agricultural mulching machine is driven by a motor to rotate the first rotating shaft, which in turn drives the pressure roller, inner ring sleeve, connecting block, sliding rod, sliding block, and arc block to rotate. When the arc block rotates and presses the film onto the ground, the pressure pushes the arc block, sliding block, and sliding rod to slide into the inner groove, compressing the compression spring. This pressure force expels the air under the film. When the arc block rotates to another direction, the compression spring rebounds, pushing the sliding rod, sliding block, and arc block back to their original positions. This reduces the amount of gas trapped under the film, improves the adhesion between the film and the ground, and enhances the practicality of the mulching mechanism of the agricultural mulching machine.

[0013] 2. The film covering mechanism of this agricultural film covering machine is driven by a first servo motor to rotate the second transmission shaft, the drive gear and the driven gear, and the first transmission shaft. This drives two rotating rods to rotate, allowing the positions of the crossbar, connecting rod, first connecting shaft, guide roller, first rotating shaft, pressure roller, inner ring sleeve, connecting block and arc block to be adjusted according to usage requirements. This facilitates the guidance of the film and makes it easier to press the film onto the ground, thus improving the practicality of the film covering mechanism of the agricultural film covering machine.

One end of the compression spring 19 is fixedly connected to the inner wall of the internal groove 17, and the other end of the compression spring 19 is fixedly connected to one side of the sliding rod 18. Through the cooperation of the compression spring 19, the connecting block 16, and the sliding rod 18, when the arc block 21 rotates to press the film 12 onto the ground, the pressure pushes the arc block 21, the sliding block 20, and the sliding rod 18 to slide into the internal groove 17, compressing the compression spring 19. This allows the air under the film 12 to be expelled through the pressing force. When the arc block 21 rotates to another direction, the compression spring 19 rebounds, thereby pushing the sliding rod 18, the sliding block 20, and the arc block 21 to reset. A crossbar 8 is fixedly connected between the two rotating rods 7. Two corresponding connecting rods 9 are fixedly connected to the outside of the crossbar 8. A first connecting shaft 10 is fixedly connected between the two connecting rods 9. A guide roller 11 is rotatably connected to the outside of the first connecting shaft 10. The guide roller 11 can guide the film 12, thereby facilitating the pressing of the film 12 onto the ground. The mounting frame 1 has two corresponding rotating seats 24 rotatably connected inside by a rotating shaft. The mounting frame 1 has an insertion groove 23 inside, and the rotating seat 24 has a first slot 25 inside. A central shaft 26 is inserted into the first slot 25. An unwinding roller 30 is sleeved on the outside of the central shaft 26. The unwinding roller 30 and the rotating seat 24 are both fixedly connected to two corresponding limiting rods 29. The central shaft 26 has two corresponding limiting grooves 27 inside, and the limiting rods 29 are inserted into the limiting grooves 27. An insertion block 28 is inserted into the insertion groove 23. A film 12 is provided on the outside of the unwinding roller 30. Through the mutual cooperation of the insertion groove 23, the first slot 25, the central shaft 26, the limiting groove 27, the insertion block 28 and the limiting rods 29, it is convenient to replace the unwinding roller 30 and the film 12. The mounting bracket 1 has a fixed electromechanical box inside, and the electromechanical box has a fixed second servo motor 31 inside.

An electromechanical box is installed on the outside of one of the rotating rods 7. A drive motor 22 is fixedly installed inside the electromechanical box. The output end of the drive motor 22 is fixedly connected to the first rotating shaft 13 through a coupling.

[0018] In summary, the mulching mechanism of this agricultural mulching machine is used as follows: The operator installs and fixes the mounting frame 1 onto the mulching machine, then powers on each mechanism. The first servo motor 6 is then started via an external control device, driving the second transmission shaft 4, the drive gear 5, the first transmission shaft 2, and the driven gear 3 to rotate. This causes the two rotating rods 7 to rotate. The rotating rods 7 are then lifted, and the insertion block 28 is disassembled. The central shaft 26 is then removed from the first slot 25 and the insertion slot 23. The unwinding roller 30 is then lifted between the two rotating seats 24. The central shaft 26 is then inserted through the first slot 25 and the unwinding roller 30 to fix it in place. The insertion block 28 is then inserted into the insertion slot 23 and secured with bolts. The film 12 on the outside of the unwinding roller 30 is then pulled out and fixed to the ground. Finally, the controller starts the first servo motor 6, driving the second transmission shaft 4, the drive gear 5, the driven gear 3, and the first transmission shaft 2 to operate. The two rotating rods 7 are driven to rotate, thereby adjusting the angles of the guide roller 11, the first rotating shaft 13, the pressure roller 14, the inner ring sleeve 15, the connecting block 16, and the arc block 21. Then, the film is moved by the film coating machine. At the same time, the second servo motor 31 is started to drive the rotating seat 24 to rotate, thereby driving the central shaft 26 and the unwinding roller 30 to rotate, thus extending the film 12. The guide roller 11 can guide the film 12. Then, the drive motor 22 drives the first rotating shaft 13 to rotate. When the arc block 21 rotates and presses the film 12 onto the ground, the pressure pushes the arc block 21, the sliding block 20, and the sliding rod 18 to slide into the inner groove 17, causing the compression spring 19 to be compressed. Thus, the air under the film 12 is discharged through the pressing force. When the arc block 21 rotates to other directions, the compression spring 19 rebounds, thereby pushing the sliding rod 18, the sliding block 20, and the arc block 21 to return to their original positions. At the same time, the two pressure rollers 14 can press the two sides of the film 12 onto the ground.
