In addition, in addition to indicating the orientation or positional relationship, the above-mentioned terms can also be used to indicate other meanings, for example, the term "upper" can also be used to indicate a certain dependent relationship or connection relationship in some cases. For those skilled in the art, the specific meaning of these terms in the present application can be understood according to the specific circumstances.

[0034] The present embodiment provides a transplanter mulcher, comprising a base plate for fixed connection with a frame. Specifically, the frame can be part of a planting portion of a transplanter, so that the transplanter mulcher rises or falls with the planting portion of the transplanter.

[0035] It is worth emphasizing that the number of the term "several" in the present embodiment is two or more, for example, 2, 3, 4, 5 or 6, etc.

[0036] As Figure 1 , 2As shown, the rice transplanter film applicator further comprises a film shaft 100, a support plate 200 and a plurality of film pressing assemblies 300. The film shaft 100 is rotatably connected to the base plate for mounting the film roll. Specifically, the film shaft 100 can be rotatably connected to the base plate through a bearing, which provides a certain tensioning force so that the film shaft 100 provides the film that is tensioned to a certain extent. The support plate 200 is fixedly installed to the base plate and extends along the axial direction of the film shaft 100, for providing support force for the film pressing assemblies 300. Specifically, the support plate 200 can be a long strip plate, or a half-barrel shape or a rectangular shape, etc.

[0037] As shown, Figure 2 each film pressing assembly 300 comprises a pressing plate 310, a film pressing shaft 320 and a plurality of film pressing rollers 330.

[0038] As shown, Figure 2 the plurality of film pressing assemblies 300 are arranged in sequence along the axial direction of the film shaft 100, one side edge of the pressing plate 310 is hingedly connected to the support plate 200, the side edge of the pressing plate 310 away from the support plate 200 is provided with a mounting hole, the film pressing shaft 320 is detachably inserted through the mounting hole, and the plurality of film pressing rollers 330 are sleeved to the film pressing shaft 320, and the film pressing rollers 330 can rotate relative to the film pressing shaft 320. Specifically, in one film pressing assembly 300, the total axial width of the plurality of film pressing rollers 330 is adapted to the length of the film pressing shaft 320. An elastic member 340 is arranged between the pressing plate 310 and the support plate 200, and the elastic member 340 applies pressure to the pressing plate 310, so that the film pressing rollers 330 are pressed downward.

[0039] Specifically, as shown, Figure 2 with the vertical direction as the reference, the axis height of the film pressing shaft 320 is lower than the axis height of the film shaft 100. The film shaft 100 can output the film to the bottom of the film pressing rollers 330, and the film pressing rollers 330 are used to paste the film to the field to prevent the film from not being pasted to the field.

[0040] In this way, since the film pressing shaft 320 is designed in a detachable form, the user can replace the length of the film shaft 100 according to the arrangement of the seedling needles of the rice transplanter, and adaptively install the number of rollers on the film shaft 100, and adjust the specifications or the pressure of the different film pressing assemblies 300 to meet various application requirements.

[0041] As a detailed scheme, as shown, Figure 1 , 2As shown, the scheme comprises four film pressing assemblies 300, each of which comprises a film pressing shaft 320. Among the four film pressing assemblies 300, the film shafts 100 in the two film pressing assemblies 300 near the two outer sides of the film presser are longer, and are provided with five film pressing rollers 330, while the film shafts 100 in the two film pressing assemblies 300 in the middle are shorter, and are provided with two film pressing rollers 330, so as to adapt to the seedling needles of the six-row rice transplanter. If the seedling needles of an eight-row rice transplanter are to be adapted, the shorter film shafts 100 in the two film pressing assemblies 300 in the middle can be removed and replaced with longer film shafts 100, and the number of rollers on the film shafts 100 can be increased, so as to adapt to the seedling needles of the eight-row rice transplanter.

[0042] In some special areas, the water and soil conditions are different, and the user can also replace the material or weight of the film pressing roller 330, so as to adjust the pressure of the film pressing assembly 300, and thus adapt to the planting environment in multiple areas.

[0043] Specifically, as shown in Figure 2 , the two ends of the film pressing shaft 320 are respectively provided with detachable limit members 350, the limit members 350 are located outside the film pressing roller 330, and at least part of the limit members 350 exceeds the inner hole of the film pressing roller 330. The limit member 350 can limit the axial movement of the film pressing roller 330. Optionally, the limit member 350 can be a snap ring or the like structure, which is sleeved on the film shaft 100, or a plug shaft or the like structure, which is inserted into the inner hole of the film shaft 100. More specifically, other components can be provided between the limit member 350 and the film pressing shaft 320, and the limit member 350 can also directly abut against the film pressing roller 330.

[0044] As a preferred scheme, as shown in Figure 2 , the limit member 350 is a bolt, and the limit member 350 is threadedly connected with the film pressing shaft 320. This design takes advantage of the larger head of the bolt to axially limit the film pressing roller 330, and at the same time, enables the entire film shaft 100 to be further quickly disassembled from the pressing plate 310.

[0045] Specifically, as shown in Figure 3 , the pressing plate 310 comprises an inner plate 311, and two parallel connecting rods 312 are arranged on the two sides of the inner plate 311. The ends of the two connecting rods 312 are respectively formed with mounting holes for the film pressing shaft 320 to pass through.

[0046] More specifically, as shown in Figure 3 , 4 , the two connecting rods 312 protrude relative to the inner plate 311, so that an avoiding space 313 is formed between the two connecting rods 312. The avoiding space 313 is provided with the film pressing roller 330, so as to make full use of the space and cooperate with the dense seedling needles, so as to prevent the local unevenness of the mulching film at the positions corresponding to the seedling needles when the seedling needles of the rice transplanter plant seedlings.

[0047] Preferably, as shown in the figure, the elastic member 340 is a torsion spring, which is structured to be matched with the pressing plate 310, so that the pressing plate 310 can deliver more balanced pressure to the film pressing roller 330, and the user can also replace the torsion spring of different specifications to adjust the pressure of the film pressing roller 330. Figure 4

[0048] As other solutions, the elastic member 340 can also be a compression spring or other structures, but it is equivalent to a compression spring, which is more complex to install, difficult to adapt to the muddy working environment of the rice transplanter, and makes the pressing plate 310 unbalanced in force, and the film pressing roller 330 is unstable when pressing the film.

[0049] In order to solve the problem that the two sides of the mulching film are easily blown up by the wind after the mulching film covers the ground, as a preferred solution, as shown in the figure, Figure 1 2 The two end portions of the film shaft 100 are respectively a first film pressing assembly 300 and a second film pressing assembly 300, and the first film pressing assembly 300 and the second film pressing assembly 300 each include a film pressing sheet 360, which is located at the outer side end of the film shaft 100 and is sleeved to the film shaft 100. The radial surface of one side of the film pressing sheet 360 is in close contact with the film pressing roller 330. Specifically, the film pressing sheet 360 can rotate relative to the film shaft 100. The axial width of the film pressing sheet 360 is smaller than the axial width of the film pressing roller 330, and the outer diameter of the film pressing sheet 360 is larger than the outer diameter of the film pressing roller 330. Therefore, the film pressing sheet 360 has a large outer diameter and a small thickness, and the film pressing sheet 360 is synchronously installed with the film pressing roller 330 to the film shaft 100, can be followed by the pressing plate 310 and the film pressing roller 330 to be synchronously pressed, has a small contact area with the mulching film, can press the side edges of the mulching film, and the film pressing sheet 360 has insufficient pressure, which causes the mulching film to be blown up.

[0050] Specifically, as shown in the figure, the film pressing sheet 360 is located between the limiting member 350 and the film pressing roller 330. Figure 2

[0051] As a preferred solution, as shown in the figure, the support plate 200 is semi-cylindrical, the film shaft 100 is located inside the support plate 200, and the pressing plate 310 is connected to the outer wall of the support plate 200. The support plate 200 can protect the film shaft 100 to a certain extent, and can effectively support the film pressing assembly 300. Figure 2 As a specific solution, the embodiment also provides a rice transplanter, which includes a planting part and the rice transplanter mulcher in the above-mentioned solution. The rice transplanter mulcher is installed on the planting part, and the planting part includes a seedling needle. The film pressing range of the film pressing roller 330 corresponds to the transplanter range of the seedling needle in the transverse direction. The rice transplanter mulcher can fully adapt to the seedling needle and make adaptive adjustment according to the use demand.
