[0059] A driving mechanism 7 is fixedly installed on the top of the frame 1, and the driving mechanism 7 includes a driving motor 701. The driving motor 701 is fixedly installed on the top of the frame 1. The output shaft of the driving motor 701 is fixedly connected with a screw rod 702. Both ends of the screw rod 702 are rotatably connected with screw rod brackets 703. The two screw rod brackets 703 are fixedly installed on the top of the frame 1. The surface of the screw rod 702 is threadedly connected with a moving block 704. The moving block 704 is fixedly connected with a push plate 705 through a cylinder.

[0060] The frame 1 is provided with a transverse groove adapted to the movement of the push plate 705 .

[0061] A plowing mechanism 8 is fixedly installed inside the frame 1, and the plowing mechanism 8 includes a fixed plate 801, a lifting block 803 is fixedly installed on one side of the fixed plate 801, two transverse grooves 808 are provided on the fixed plate 801, the lifting block 803 is slidably connected to the fixed plate 801 through a slide plate 802, five plowing plates 804 are penetrated through the lifting block 803, and extension shafts 805 are fixedly installed on both sides of the lifting block 803, and the surfaces of the two extension shafts 805 are fixedly connected to a fixing frame 807 through a spring 806, and the top of the fixing frame 807 is fixedly connected to the bottom of the frame 1.

[0062] An adsorption mechanism 9 is fixedly installed on one side of the lifting block 803, and the adsorption mechanism 9 includes a second fixing frame 901. The surfaces of the two second fixing frames 901 are fixedly connected to a third fixing frame 903 through a second spring 902. An adsorption connecting frame 904 is commonly fixedly installed on the bottom of the two third fixing frames 903. An extension shaft 2 905 is fixedly installed on both sides of the adsorption connecting frame 904. A pneumatic suction cup 906 is symmetrically fixedly installed on the bottom of the adsorption connecting frame 904.

[0063] A fixing frame four 15 is symmetrically fixedly installed at the bottom of the frame 1, and the surfaces of the two fixing frames four 15 are fixedly connected to the tensioning wheel 11 through the spring three 14, and the ground film 16 is pulled out from above the tensioning wheel 11.

[0064] The bottoms of the five plowshares 804 are all needle-tip shaped, and the surfaces of the five plowshares 804 near the bottoms are all fixedly mounted with barbs 17 .

[0065] In actual use, during row sowing, the sweet clover seeds slowly fall from the spiral of the non-working spiral column 13 for spreading;

[0066] The push plate 705 is adapted to be installed with the extension shaft 1 805, the extension shaft 2 905 and the tensioning wheel 11;

[0067] The three spreading tubes 204 do not contact the ground film 16 and the plowing mechanism 2 when rotating;

[0068] The bottom of the push plate 705 is arc-shaped on both sides and the bottom can contact the extension shaft 1 805 and the extension shaft 2 905 at the same time;

[0069] The spiral column 13 is fixed at the bottom center of the connecting pipe 203 and does not conflict with the positions of the three spreading pipes 204 .

[0070] The working principle of the film-covered planting equipment for dryland planting of sweet clover provided in this embodiment is as follows:

[0071] First, when row sowing is carried out, the work in Example 1 is carried out, and a tensioning wheel 11 is added to allow the ground film 16 to pass around the tensioning wheel 11 for covering, and the driving motor 701 is started to drive the screw 702 to rotate. The screw 702 drives the push plate 705 to move to the tensioning wheel 11 through the moving block 704, and the push plate 705 presses down the tensioning wheel 11, driving the ground film 16 to cover the ground for covering.

[0072] Then, when encountering mountainous, hilly and sloping farmlands, row sowing is inconvenient, so it is replaced by broadcast sowing. The plowing cylinder 301 is lifted to separate the plowshare 303 from the soil. At this time, the sowing motor 12 is started to drive the spiral column 13 to rotate, and the connecting pipe 203 is also driven to rotate through the spiral column 13, thereby achieving the purpose of driving the spreading pipe 204 to rotate for broadcasting when more seeds are needed for sowing.

[0073] Then, start the driving motor 701 to drive the push plate 705 to move. At this time, the push plate 705 disengages from the tensioning wheel 11, and the tensioning wheel 11 is reset by the spring three 14. When the push plate 705 moves to the extension shaft 805, the downward-pressed lifting block 803 slides inside the fixed plate 801 and automatically limits its position when it reaches the bottom. The plow harrow 804 fixed on the lifting block 803 enters the soil 2-3 cm. At the same time, the barb 17 will play a role in preliminarily fixing the ground film 16. Shallow raking is performed when the device moves to allow the seeds and soil to be fully mixed.

[0074] Then, the driving motor 701 drives the push plate 705 to move to the left and press down the extension shaft 2 905. At this time, the push plate 705 does not separate from the extension shaft 1 805. The extension shaft 2 905 that is pressed down can drive the pneumatic suction cup 906 to press down to the ground and then adsorb the ground film 16. Then, the driving motor 701 drives the push plate 705 to only separate from the extension shaft 2 905, and the spring 2 902 drives the reset pneumatic suction cup 906 to return to a higher position. At this time, the ground film 16 fixed by the pneumatic suction cup 906 is no longer covered during the sowing process, and the ground film 16 can be tensioned by the tensioning wheel 11. When the seeds are sown, it will not cause damage to the rear structure and waste seeds. The seeds in contact with the ground film 16 will fall on the ground according to the fixed position.

[0075] Finally, when sowing is still needed, the push plate 705 is driven by the driving motor 701 to continue to move to the left, first contacting the extension shaft 905, and the pneumatic suction cup 906 returns to the ground again. As the device continues to move forward, the ground film 16 is covered again, and the driving motor 701 drives the push plate 705 to disengage from the extension shaft 1 805 and the extension shaft 2 905, and the pneumatic suction cup 906 is reset, and the harrow 804 is reset by the spring 1 806 and no longer harrows the ground.

[0076] Finally, the driving motor 701 drives the push plate 705 to move to the tensioning wheel 11 again, and the push plate 705 presses down the tensioning wheel 11, and drives the ground film 16 to cover the ground for film covering again. At the same time, the plowing mechanism 3 works again, and the device returns to the row sowing state again.

[0077] Compared with the related art, the film-covered planting equipment for dryland planting of sweet clover provided in this embodiment has the following beneficial effects:

[0078] By setting a sowing motor 12 to drive the spiral column 13, the device can be changed to a state of sowing seeds. By setting a driving motor 701 to drive the push plate 705, the tension wheel 11 can be close to the ground for covering with film during row sowing. When changing to broadcast sowing, the tension wheel 11 can be lifted to drive the ground film 16 to rise. When the seeds are broadcast, it will not cause damage to the rear structure and waste seeds. At the same time, the push plate 705 controls the plow 804 to perform shallow raking and the pneumatic suction cup 906 to absorb the ground film 16. When switching to row sowing, the plowing mechanism 3 works again and automatically covers the film. The automatic switching between row sowing and broadcasting can carry out the sowing of sweet clover seeds under different terrain conditions, thereby achieving full coverage of the terrain and improving land use efficiency, solving the inconvenience of sowing when there is a slope that is not convenient for row sowing, and improving economic benefits.
