[0017] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] It will be understood that the terms "first," "second," etc. used herein may be used to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish a first element from another element.

[0019] like Figure 1 、 Figure 9 and Figure 10 As shown, in one embodiment, a device for laying mulch film for agricultural planting is provided, the device comprising: The planter 1 includes a frame 101 provided on the planter 1. Two connecting posts 102 for docking with a traction device are fixedly mounted on the surface of the frame 101. A fixed half-frame plate 103 is fixedly mounted on the surface of the frame 101. Soil gathering mechanism 2: includes four bending plates 201 mounted on the frame 101 for gathering soil, the surfaces of each of the two bending plates 201 are slidably connected to the compression blocks 202 for compressing the soil, and also includes two nailers 204 mounted on the fixed half-frame plate 103 for fixing the unwinding end of the ground film roll 203, and also includes a soil covering scraper 205 mounted on the frame 101 for scraping the soil, and a rotating roller for guiding the ground film roll 203 is rotatably mounted on the fixed half-frame plate 103, and the two nailers 204 are both connected to the output end of the external controller; Reciprocating mechanism 3: drives the bending plate 201 and the compression block 202 to compress the soil through the driving of the rotating mechanism 4; Unwinding mechanism 5: used to drive the ground film roll 203 to unwind; Film pulling mechanism 6: used to pull the ground film for positioning; Driving mechanism 7: used to drive the bending plate 201 and the compression block 202 close to the ground.

[0020] In actual application, when the land is sown and the ground film is laid, the device is connected to the traction device through the connecting column 102, and the traction device drives the frame 101 to move. When the sowing position is reached, the traction device stops moving. Figure 10 As shown, the driving mechanism 7 drives the bending plate 201 close to the land, and the traction device continues to move and turns the soil for sowing. When the head end of the local film roll 203 is close to the sowing position, as shown in FIG. Figure 9 As shown, the film roll 203 is pulled in the opposite direction of the movement of the traction device by the film pulling mechanism 6, and is unwound under the action of the unwinding mechanism 5. At this time, the vertical facing position of the nailer 204 is located at the same point of the land through relative movement. When it moves to the end of the film pulling mechanism 6, the film pulling mechanism 6 loosens the head end of the film roll 203, and feeds back a signal to the nailer 204 through the controller. The nailer 204 extends a fixing nail to fix the head end of the film roll 203 on the ground, thereby achieving the purpose of automatically positioning and fixing the head end of the film roll 203. As the traction device moves, the excess soil that has been sown is turned over, as shown in FIG. Figure 10As shown, through the contraction effect between the two bending plates 201, the soil is gathered into the trapezoidal space formed by the two bending plates 201 and the compression block 202, and the two bending plates 201 are driven to move toward each other by the action of the reciprocating mechanism 3. At the same time, the compression block 202 moves vertically downward under the action of the reciprocating mechanism 3, compressing the soil between the two bending plates 201 and the compression block 202 to achieve a compacting effect. On the one hand, the ground film is supported when it is laid, and on the other hand, the compacted soil will not be loose, so that a space is formed on both sides of the sowing soil. The trapezoidal raised path ensures the stability of the support for the ground film, thereby achieving the purpose of automatically supporting the ground film and preventing seeds from being sunburned by heat when in contact with the ground film after germination. After the soil is gathered, as the ground film is laid, the soil at the edge of the ground film is turned up by the soil covering scraper 205, and the turned up soil falls on the edge of the ground film, thereby achieving the purpose of automatically covering and fixing the edge of the ground film. After the ground film is laid, the ground film is cut off by an external shearing device, and the head end of the cut ground film roll 203 is clamped again by the film pulling mechanism 6 to facilitate the next film laying operation.

[0022] In practical application of the embodiment of the present invention, when the driving mechanism 7 completes the operation of bringing the bending plate 201 close to the ground, as shown in FIG. Figure 10 As shown, at this time, the rotating platform 306 is driven to rotate by the rotating mechanism 4. The rotation of the rotating platform 306 drives the vertical rod 305 to perform a reciprocating motion in the vertical direction through the cooperation of the annular wave block 307 and the vertical rod 305, thereby driving the compression block 202 to perform a reciprocating motion in the vertical direction, as shown in FIG. Figure 12As shown, the movement of the vertical rod 305 drives the two sliding rods 301 to move back and forth in opposite directions through the swing of the swing rod 304, and then drives the two bending plates 201 to move back and forth in opposite directions. At this time, the two bending plates 201 cooperate with the compression block 202 to continuously compress the soil between them, thereby achieving the purpose of compacting the soil and improving the stability of the ground film support.

Figure 5 and Figure 8 As shown, at this time, the rotating motor 404 starts to run. The operation of the rotating motor 404 drives the driven gear 402 to rotate through the transmission action of the gear, and then drives the rotating platform 306 to rotate through the bevel gear set 401. The operation of the reciprocating mechanism 3 compresses the soil through the two bending plates 201 and the compression block 202, thereby achieving the purpose of compacting the soil.

[0025] like Figure 4 and Figure 5 As shown, as another preferred embodiment of the present invention, the unwinding mechanism 5 includes an unwinding gear 501 rotatably mounted on the fixed half-frame plate 103 and cooperating with the linkage gear 405, and a telescopic rotating shaft 502 for fixing the ground film roll 203 is coaxially fixedly mounted on the surface of the unwinding gear 501, and the telescopic rotating shaft 502 passes through the fixed half-frame plate 103 and is rotatably connected to the fixed half-frame plate 103.

[0026] In practical application of the embodiment of the present invention, after the driving mechanism 7 completes the operation of the bending plate 201 approaching the ground, as shown in FIG. Figure 5 As shown, at this time, the operation of the driving mechanism 7 drives the linkage gear 405 to engage with the unwinding gear 501, and the operation of the rotating mechanism 4 drives the unwinding gear 501 to rotate, and then drives the ground film roll 203 to perform the unwinding operation through the telescopic rotating shaft 502, thereby achieving the purpose of automatic unwinding when laying the ground film.

[0028] When the embodiment of the present invention is actually used, when the driving mechanism 7 drives the bending plate 201 close to the ground, the driving mechanism 7 drives the active gear 403 to mesh with the moving rack 601, and drives the moving rack 601 to move in the opposite direction of the traction device through the operation of the rotating mechanism 4, and then drives the groove table 603 to move in the opposite direction of the traction device through the sliding block 602. The movement of the groove table 603 pulls the ground film roll 203 toward the position of the triangular touch plate 608 through the extrusion cylinder 606, and at the same time, the ground film roll 203 is unwound through the movement of the unwinding mechanism 5. As the groove table 603 drives the extrusion contact 607 to contact the triangular touch plate 608, the triangular touch plate 608 feeds back a signal to the controller, so that the nailer 204 nails and fixes the head end of the ground film roll 203, and at the same time, through the limiting effect of the triangular touch plate 608, as shown Figure 7 As shown, the two extrusion contacts 607 move in opposite directions, and then the two extrusion cylinders 606 are driven to move in opposite directions through the two groove sliders 604, thereby achieving the purpose of positioning and fixing the head end of the ground film roll 203.
