Example
[0033] This embodiment provides, for example Figures 1-6 The agricultural mulching machine shown includes a U-shaped frame 1 with the opening facing backward and horizontally arranged. The frame 1 includes a transverse rod 11 and a longitudinal rod 12. The two ends of the transverse rod 11 are respectively fixedly connected to the front ends of the two longitudinal rods 12.
[0034] Between the two longitudinal bars 12, a first horizontal bar 13, a second horizontal bar 14, and a third horizontal bar 15 are arranged horizontally from front to back. The first horizontal bar 13, the second horizontal bar 14, and the third horizontal bar 15 are all fixedly erected on the longitudinal bars 12. The first horizontal bar 13, the second horizontal bar 14, and the third horizontal bar 15 are arranged parallel to each other with the transverse bars 11. A connecting seat 8 is installed in the middle of the front side of the transverse bar 11. At the fixed connection points between the first horizontal bar 13, the second horizontal bar 14, and the third horizontal bar 15 and the longitudinal bars 12, there are also fixing clamps. Through the fixing clamps, the connection between the first horizontal bar 13, the second horizontal bar 14, the third horizontal bar 15 and the longitudinal bars 12 can be made more stable, thereby improving the structural strength and stability of the frame 1.
[0035] The frame 1 is provided with a placement component 2 for placing mulch film. The placement component 2 includes two vertical support rods 21. The lower ends of the two support rods 21 are respectively fixed to the two ends of the second crossbar 14.

A shaft 23 is placed between the two retaining rings 22. Mulch film is wound on the shaft 23. The shaft 23 is connected to the mulch film component 3 through the mulch film.
[0036] The film covering assembly 3 includes two sets of vertical first uprights 31, which are located on the front and rear sides of the first horizontal bar 13 respectively. Each set of first uprights 31 has two, and the upper ends of the two first uprights 31 in each set are fixedly connected to the end and middle of the first horizontal bar 13 respectively. The lower ends of the first uprights 31 are fixedly connected to horizontal connecting plates 32. The lower sides of the two connecting plates 32 in each set are fixedly connected to horizontal first rotating rods 33. A first roller 34 is rotatably sleeved on the first rotating rod 33, and the film passes through the first roller 34 and connects to the first pressing assembly 4.
[0037] The first film pressing assembly 4 includes a horizontally arranged fixed plate 41 and two sets of vertical second uprights 42. The two sets of second uprights 42 are located on the left and right sides of the fixed plate 41, respectively. The fixed plate 41 is fixed to the middle of the lower surface of the third crossbar 15. Each set of second uprights 42 has two. The upper ends of the two second uprights 42 in each set are fixed to the ends of the adjacent third crossbar 15 and one side of the fixed plate 41, respectively. The lower ends of the second uprights 42 are rotatably connected to vertical pressure rollers 43 through shafts. The film passes through the pressure rollers 43 and is connected to the film cutting assembly 5.
[0038] The film cutting assembly 5 includes two vertically arranged arc-shaped cutters 51 and two horizontally arranged first support plates 52. The two cutters 51 are placed on the left and right sides of the rear of the third crossbar 15, with the concave surface of the cutters 51 facing forward and the cutting edge of the cutter 51 located at the lower end. The two first support plates 52 are fixed on the left and right sides between the second crossbar 14 and the third crossbar 15, respectively. A vertical first pillar 53 is fixedly connected to the connection between the second crossbar 14 and the first support plate 52. A first hydraulic cylinder 54 is provided at the upper end of the first pillar 53. The cylinder body of cylinder 54 is hinged to the upper end of the first support column 53. The output end of the first hydraulic cylinder 54 is hinged to a vertical first connecting rod 55. The lower end of the first connecting rod 55 is fixedly connected to the upper end of the cutter 51. Each first support plate 52 has a first hinge member 56 horizontally arranged on the left and right sides behind it. The front side of the first hinge member 56 is fixedly connected to the rear side of the third crossbar 15. The rear side of the first hinge member 56 is hinged to a second connecting rod 57. The other end of the second connecting rod 57 is hinged to a second hinge member 58. The second hinge member 58 is fixedly connected to the upper concave surface of the cutter 51.
[0039] Before use, first install the sleeve wrapped with mulch film on the shaft 23, and then connect the mulching machine to vehicles such as rice transplanters through the connecting seat 8 to prepare for use.
[0040] During use, as the mulching machine moves along with the rice transplanter, the mulch film is laid out in the rice planting area. First, the first roller 34 unfolds the mulch film in the paddy field and presses it underwater. Then, the pressure roller 43 presses both sides of the mulch film into the soil of the paddy field, fixing the mulch film in place and ensuring better contact with the paddy field. This avoids the problem of the mulch film floating due to water buoyancy when manually mulching in the paddy field, thus improving the mulch film's ability to inhibit weed growth and providing warmth and moisture retention, thereby increasing rice yield. After the mulch film is laid, the first hydraulic cylinder 54 is controlled to extend and retract to drive the first connecting rod 55, which in turn drives the cutter 51 to cut the laid mulch film, thus completing the mulch film laying. This solves the problem of traditional manual mulching planting, making it convenient for workers to use. It not only reduces the labor intensity of workers but also reduces labor costs and improves labor efficiency. The cooperation between the first hinge 56, the second connecting rod 57, and the second hinge 58 can assist and limit the movement of the cutter 51.
[0041] Furthermore, a second pressing assembly 6 is provided on the frame 1. The second pressing assembly 6 includes two horizontally arranged second support plates 61. The two second support plates 61 are fixed between the second crossbar 14 and the third crossbar 15, one on the left and one on the right respectively. A vertical second column 62 is fixedly connected to the connection between the second crossbar 14 and the second support plate 61. A second hydraulic cylinder 63 is provided at the upper end of the second column 62. The cylinder body of the second hydraulic cylinder 63 is hinged to the upper end of the second column 62. A connecting ring 64 is fixedly connected to the output end of the second hydraulic cylinder 63.
[0042] A third connecting rod 65 is hinged to the front end of the longitudinal rod 12 and the left and right sides of the front end of the fixed plate 41. The other end of the third connecting rod 65 is fixedly connected to a vertical third upright rod 66, and the rear ends of several third connecting rods 65 are all on the same horizontal line. A second rotating rod 67 is horizontally provided between the fixed plate 41 and the longitudinal rod 12. The two ends of the second rotating rod 67 are fixedly connected to the upper ends of the adjacent third upright rods 66. The connecting ring 64 is rotatably sleeved on the adjacent second rotating rod 67. A second roller 68 is horizontally provided directly below the second rotating rod 67. The two ends of the second roller 68 are fixedly connected to the lower ends of the adjacent third upright rods 66. The second roller 68 is located between the pressure roller 43 and the cutter 51.
[0043] With the second pressing film assembly 6 in place, when the middle pressure roller 43 of the first pressing film assembly 4 presses the edge of the mulch film, the second hydraulic cylinder 63 is controlled to extend and retract, causing the second hydraulic cylinder 63 to drive the second rotating rod 67 to rotate through the connecting ring 64. The second rotating rod 67 then drives the second roller 68 to rotate around the hinge point between the third upright rod 66 and the fixed plate 41 through the third upright rod 66. This allows the second roller 68 to press the middle part of the laid mulch film into the paddy field, making it better in contact with the paddy field. This further avoids the problem that the mulch film is easy to float up due to the buoyancy of the water when planting with mulch film by hand in the paddy field. This improves the effect of using the mulch film to inhibit the growth of weeds and to keep warm and moist, thereby increasing the yield of rice.
[0044] After the plastic film is cut, the second hydraulic cylinder 63 moves in the opposite direction as described above to bring up the second roller 68 to fit with the cutter 51, so that the end of the plastic film is clamped after it is cut. When the rice transplanter turns around to cover other areas of paddy fields with plastic film, it can continue to cover the fields, which can save manpower.
[0045] Furthermore, sleeves 7 are slidably fitted on the first upright 31, the support rod 21, and the second upright 42. The first upright 31, the support rod 21, and the second upright 42 are respectively connected to the sleeves 7 by bolts, and the first upright 31, the support rod 21, and the second upright 42 are respectively fixedly connected to the first crossbar 13, the second crossbar 14, and the third crossbar 15 through the sleeves 7.
[0046] The sleeve 7 allows for height adjustment of the first roller 34 at the lower end of the first upright 31, the retaining ring 22 at the upper end of the support rod 21, and the pressure roller 43 at the lower end of the second upright 42. This not only allows the first roller 34 and the pressure roller 43 to make better contact with the paddy field as needed, but also makes it easier to adjust and use the retaining ring 22 for placing the plastic film.
[0047] In summary, the agricultural mulching machine provided by this utility model not only solves the problem of traditional manual mulching planting, making it convenient for workers to use, reducing labor intensity and labor costs, but also improves labor efficiency. Furthermore, it avoids the problem of the mulch film easily floating due to water buoyancy when mulching is done manually in paddy fields, thereby enhancing the mulch film's ability to inhibit weed growth and providing warmth and moisture retention, thus increasing rice yield.
[0048] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
