The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0019] An agricultural seedling raising and mulching device according to an embodiment of the present application is described below with reference to the drawings.

[0020] As shown in the drawings, Figures 1-5 The agricultural seedling raising and mulching device according to an embodiment of the present application can include a walking frame 1 and two sets of film pressing mechanisms 2.

[0021] The walking frame 1 is provided with two fixed rods 11 and guide rollers 12 arranged symmetrically and rotatably, and a plurality of wheel bodies 13 are installed on the walking frame 1, and a film roll is sleeved on the two fixed rods 11.

[0022] It should be noted that the two fixed rods 11 described in this embodiment are used to support the film roll, and the guide rollers 12 are used to flatten and guide the film during film release.

[0023] The two sets of film pressing mechanisms 2 are symmetrically arranged on the walking frame 1, and the film pressing mechanism 2 includes a supporting assembly 21, a pressing assembly 22, an extension rod 23, a flattening assembly 24 and a stacking assembly 25.

[0024] The supporting assembly 21 is connected with the walking frame 1, the pressing assembly 22 is rotatably connected with the supporting assembly 21, and the pressing assembly 22 abuts against the film, and the pressing assembly 22 is used to roll the edge of the film to place it inside the soil.

[0025] The extension rod 23 is connected with the supporting assembly 21, the flattening assembly 24 is installed on the extension rod 23, the flattening assembly 24 is connected with the pressing assembly 22, the flattening assembly 24 can slide on the surface of the film, and the flattening assembly 24 is used to apply an external force to the film in the direction of the film plane near the edge of the film.

[0026] The stacking assembly 25 is installed on the extension rod 23, the stacking assembly 25 abuts against one side of the film, the stacking assembly 25 is located between the pressing assembly 22 and the flattening assembly 24, and the stacking assembly 25 is used to apply an internal force to the film at the edge of the film to form a stacking effect of the film edge.

[0027] In the embodiment of the present application, the device can be provided with traction by manpower or external mechanical equipment to perform mulching operation on the target area.

[0028] Specifically, when the relevant operator uses the device to carry out the film mulching operation on the target area (for example, a garlic planting area), first, a film roll suitable for the width of the target area (which can be determined according to the actual situation) is selected, the film roll is placed on the two fixed rods 11, one end of the film is wound around the lower part of the guide roller 12, and the film is continuously pulled to the rear of the device, and the soil is used to fix one end of the film at a preset position of the target area.

[0029] According to the width data of the film roll and the target area, the distance between the two groups of film pressing mechanisms 2 is adjusted, so that the film pressing mechanisms 2 can roll the edges of the film into the soil.

[0030] With the help of manpower or external mechanical equipment to provide traction, the wheel body 13 supports the device to move at a constant speed on the outside of the target area during the movement, and the film roll is freely released on the walking frame 1 under the pulling action of one end of the film.

[0031] The film pressing mechanism 2 moves with the walking frame 1, the pressing assembly 22 can drive the flattening assembly 24 to rotate, and the flattening assembly 24 generates sliding friction with the film. At the same time, the stacking assembly 25, which is not far from the flattening assembly 24, applies a force to the edge of the film, so that the edge of the film can form a stacking effect, and the thickness of the edge of the film increases, so that the film is not easy to break when it is rolled by the pressing assembly 22. The pressing assembly 22 can roll the stacked film edge into the soil, and the increased thickness of the film increases the friction between the film and the soil, thereby avoiding the situation that the film adheres to the pressing assembly 22 and then separates from the soil, and further ensuring the efficiency and quality of the film mulching.

[0032] In an embodiment of the present application, as shown in Figure 2 the support assembly 21 includes a frame body 211, a first rod body 212, a rotating base 213, and a first locking member 214.

[0034] In an embodiment of the present application, as shown in Figure 3 the pressing assembly 22 includes a third rod body 221, a pressing wheel 222, and a second locking member 223.

[0035] Among them, the third rod body 221 is rotationally connected with the rotating base 213, the pressing wheel 222 is movably arranged on the third rod body 221, and the second locking member 223 is arranged between the pressing wheel 222 and the third rod body 221.

[0036] In an embodiment of the present application, as shown in Figure 2 The flattening assembly 24 comprises a second rod 241, a spiral roller 242 and a transmission component 243.

[0037] The second rod 241 is connected with the extension rod 23, the second rod 241 is connected with the spiral roller 242, the spiral roller 242 can slide on the surface of the film, and the transmission component 243 is arranged between the third rod 221 and the second rod 241.

[0038] It should be noted that the spiral roller 242 described in this embodiment comprises a roller and a spiral rubber strip, and the spiral rubber strip can exert force on the outer side of the film edge during rotation.

[0039] In an embodiment of the present application, as shown in Figure 2 The stacking assembly 25 comprises a support plate 251, a first roller 252 and a third locking component 253.

[0040] The support plate 251 is movably connected with the extension rod 23, the first roller 252 is rotatably connected with the support plate 251, the first roller 252 abuts against one side of the film, and the third locking component 253 is arranged between the support plate 251 and the extension rod 23.

[0041] It should be noted that the first locking component 214, the second locking component 223 and the third locking component 253 described in this embodiment can be fixed bolts or hand screws, the specific structure and working principle of which have been disclosed by the prior art, and therefore will not be described in detail here.

[0042] As a possible case, a locking component in the form of a fixed bolt or a hand screw is also arranged between the extension rod 23 and the first rod 212, for adjusting the angle and position of the extension rod 23, so that the flattening assembly 24 and the stacking assembly 25 are placed at the preset position of the film.

[0043] Specifically, during the adjustment of the distance between the two groups of film pressing mechanisms 2 by the relevant operating personnel according to the width data of the film roll and the target area, first, the pressing wheel 222 is moved on the third rod 221, and the second locking component 223 is used to lock between the pressing wheel 222 and the third rod 221, so that the pressing wheel 222 is placed above the edge of the stacked film.

[0044] Then, the frame 211 is pushed to slide on the walking frame 1, so that the pressing wheel 222 can be placed about 3-5 cm inside the soil when rotating.

[0045] The angle of the extension rod 23 and the position on the first rod 212 are adjusted, so that the spiral roller 242 in the flattening assembly 24 abuts against the film.

[0046] The relative position between the adjusting support plate 251 and the extension rod 23 is adjusted, and the third locking member 253 is used to fix the two, so that the first roller shaft 252 exerts force on the film to obtain a stacking effect.

[0047] During operation of the film pressing mechanism 2, the pressing assembly 22 walks on the ground, drives the second rod body 241 and the spiral roller shaft 242 in the flattening assembly 24 to rotate through the transmission member 243, the spiral roller shaft 242 produces sliding friction with the film, and then exerts force on the outer side of the film edge close to the film.

[0048] During film conveying, the first roller shaft 252 in the stacking assembly 25 can limit and exert force on the film edge, so that the film edge forms a stacking effect, and when the stacked film moves to the pressing assembly 22, the press wheel 222 rolls the film into the soil.

[0049] The thickness of the film edge after stacking increases, so that the film is not easy to break when rolled by the pressing assembly 22, and the thickened film increases the friction with the soil, thereby avoiding the situation that the film is adhered to the pressing assembly 22 and then separated from the soil, and thus ensuring the efficiency and quality of the film mulching.

[0050] In an embodiment of the present application, as shown in Figure 1 and Figure 4 , the fixed rod 11 is sleeved with a conical sleeve 111, the conical sleeve 111 abuts against one end of the film roll, and the fourth locking member 112 is arranged between the conical sleeve 111 and the fixed rod 11.

[0051] It can be understood that the film roll is fixed by the conical sleeve 111 during unwinding of the film roll, which can avoid the situation that the film roll jumps during unwinding, so that the film unwinding is stable.

[0052] In addition, by arranging the conical sleeve 111 and the fourth locking member 112 on the fixed rod 11, and arranging the adjustable structures of the supporting assembly 21, the pressing assembly 22, the extension rod 23, the flattening assembly 24 and the stacking assembly 25 in the embodiment of the present application, the device can be applied to film mulching operation in planting areas of various widths, thereby expanding the application range of the device.

[0053] In an embodiment of the present application, as shown in Figure 1 and Figure 5 , it further includes two groups of symmetrical soil covering mechanisms 3, and each soil covering mechanism 3 includes a first support rod 31, a soil turning disc 32, an angle locking member 33 and a displacement locking member 34.

[0054] The first supporting rod 31 is movably connected with the walking frame 1, the soil turning disc 32 is movably connected with the first supporting rod 31, the angle locking piece 33 is arranged between the first supporting rod 31 and the soil turning disc 32, and the displacement locking piece 34 is arranged between the first supporting rod 31 and the walking frame 1.

[0055] Specifically, the position between the first supporting rod 31 and the walking frame 1 and the angle of the soil turning disc 32 are fixed by the angle locking piece 33 and the displacement locking piece 34, so that the soil turning disc 32 can transfer part of the soil on the ridge to the position passed by the compression wheel 222, that is, the damaged area and the film separated from the soil can be covered by the part of the soil, thereby further optimizing the quality of the film covering of the device.

[0056] In an embodiment of the present application, as shown in Figure 1 and Figure 5 The pulling assembly 4 is arranged on the walking frame 1.

[0057] It can be understood that the pulling assembly 4 can conveniently provide the device with traction force by manpower or external machinery.

[0058] In summary, the agricultural seedling raising and film covering device of the embodiment of the present application arranges the stacking assembly between the pressing assembly and the flattening assembly, the stacking assembly applies force to the edge of the film, so that the edge of the film forms a multi-layer stacking effect, thereby increasing the thickness of the edge of the film, so that the film is not easy to be damaged when being rolled by the pressing assembly, and the thickened film increases the friction with the soil, thereby avoiding the situation that the film is separated from the soil after being adhered to the pressing assembly, and further ensuring the efficiency and quality of the film covering.
