[0011] Preferably, there are two conveying components, which are respectively arranged on both sides of the storage box, and the two conveying components are symmetrically distributed with respect to the storage box.

[0012] Preferably, there are three soil covering mechanisms, which are arranged on the vehicle frame at equal intervals. One soil covering mechanism is arranged on each side of the vehicle frame, and the other soil covering mechanism is arranged in the middle of one end of the vehicle frame. The plowshares on the soil covering mechanisms arranged on both sides of the vehicle frame respectively correspond to the two conveying components one by one.

[0013] Preferably, the blanking component includes a first slide rail fixedly connected to the storage box. Two blanking hoppers are slidably connected to the first slide rail.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figures 1-9 , the present invention provides a technical solution:

[0032] A plastic film covering device for planting daylilies, comprising a vehicle frame 1. A fixed frame 2 is fixedly connected to the lower end of the vehicle frame 1. A rotating roller 6 and a flattening roller 7 are provided on the fixed frame 2. A winding roller 5 is provided on the vehicle frame 1. A soil covering mechanism and a film pressing mechanism that cooperate with each other are provided on the vehicle frame 1. The soil covering mechanism includes a sleeve 9 fixedly connected to the vehicle frame 1. The sleeve 9 is in spline connection with a slide rod 10. A snap ring 11 is fixedly connected to the middle part of the slide rod 10. A spring 13 is sleeved on the slide rod 10. The two ends of the spring 13 are respectively fixedly connected to the upper end face of the snap ring 11 and the lower end face of the sleeve 9. A plowshare 12 is fixedly connected to the lower end of the slide rod 10. The film pressing mechanism includes a conveying component, a storage box 19 and a blanking component that cooperate with the plowshare 12. The storage box 19 is fixedly connected to the fixed frame 2. The conveying component is used to convey the soil turned up by the plowshare 12 into the storage box 19. The blanking component is used to release the soil in the storage box 19 onto the plastic film. Preferably, the spring 13 should be made of a material with a relatively large Young's modulus to prevent the plowshare 12 from being unable to penetrate into the soil. At the same time, two flattening rollers 7 are provided to facilitate leveling the land of two side-by-side ridges. The winding roller 5 can be correspondingly set to two, or when winding the plastic film, two rolls of plastic film can be wound, or only one roll of plastic film can be wound. A corresponding cutting tool is provided in the middle part of the vehicle frame 1, and all can achieve the film covering operation for two side-by-side distributed ridges at one time.

[0033] Specifically, as Figure 1 , Figure 4 and Figure 5 shown, the conveying component includes a support frame 14 fixedly connected to the fixed frame 2. A conveyor belt 15 is provided on the support frame 14. Baffle plates 16 are fixedly connected to the support frame 14 on both sides of the conveyor belt 15. A receiving plate 17 and a conveying channel 18 are respectively fixedly connected to both ends of the baffle plate 16. The support frame 14 and the conveyor belt 15 are both inclined. The receiving plate 17 is fixedly connected to the lower end of the baffle plate 16. The conveying channel 18 is fixedly connected to the upper end of the baffle plate 16. The baffle plate 16 is communicated with one side of the storage box 19 through the conveying channel 18. Two conveying components are provided, and the two conveying components are respectively arranged on both sides of the storage box 19 and are symmetrically distributed with respect to the storage box 19. Preferably, the inclination angle of the conveyor belt 15 should not be too large, and it should be ensured that the soil can be normally conveyed and the soil will not roll down along the conveyor belt 15 due to gravity. At the same time, the conveying channel 18 should also be inclined so that the soil entering the conveying channel 18 can freely slide into the storage box 19.

[0034] Specifically, as Figure 1 and Figure 9As shown in the figure, there are three soil covering mechanisms, which are arranged at equal intervals on the frame 1. One soil covering mechanism is provided on each side of the frame 1, and the other soil covering mechanism is arranged in the middle part at one end of the frame 1. The plowshares 12 on the soil covering mechanisms arranged on both sides of the frame 1 respectively correspond to the two conveying components one by one. Preferably, the plowshares 12 are symmetrically arranged with respect to the sliding rod 10, that is, the soil turned up on both sides of the plowshares 12 should be approximately the same. Through the arrangement of the three plowshares 12, the middle plowshare 12 is located between two side-by-side ridges, and the plastic films on both sides of it are covered with soil. The soil turned up by the plowshares 12 on both sides is divided into two parts, the inner soil covers the plastic films on the outer sides of the two side-by-side ridges, and the outer soil enters the storage box 19 through the conveying component.

[0035] Specifically, as Figure 5 , Figure 6 , Figure 7 and Figure 8 shown, the blanking component includes a first slide rail 21 fixedly connected to the storage box 19. Two blanking hoppers 22 are slidably connected to the first slide rail 21. Two blanking channels 20 are opened at the lower end of the storage box 19. The two blanking channels 20 respectively correspond to the two blanking hoppers 22 one by one. A blanking port 23 is opened at the lower end of the blanking hopper 22. A second slide rail 26 is fixedly connected to one side of the storage box 19. A sliding sleeve 27 is slidably connected to the second slide rail 26. A vertical rod 28 is slidably connected inside the sliding sleeve 27. A cross bar 29 is fixedly connected to the lower end of the vertical rod 28. Support rods 30 are respectively fixedly connected to both ends of the cross bar 29. Limiting rods 31 are respectively arranged at the upper and lower ends on one side of the support rod 30. A third slide rail 25 is fixedly connected to each of the two blanking hoppers 22 through a connecting arm 24. The two third slide rails 25 respectively correspond to the two support rods 30 one by one. The third slide rail 25 is slidably connected to the two limiting rods 31 on the corresponding support rod 30. A support platform 32 is fixedly connected to the storage box 19. A driving motor 33 is provided on the support platform 32. The output end of the driving motor 33 is fixedly connected to a connecting rod 34. The end of the connecting rod 34 far from the driving motor 33 is rotatably connected to the middle part of the vertical rod 28. The two third slide rails 25 and the two support rods 30 are both inclined, and the two third slide rails 25 are symmetrically arranged with respect to the vertical rod 28. The inclination angle of the support rod 30 is the same as the inclination angle of the corresponding third slide rail 25. Preferably, the inner walls of the storage box 19 and the two blanking hoppers 22 should be inclined, so that the soil can freely slide to the blanking channel 20 due to gravity when it is inside the storage box 19. At the same time, the soil entering the blanking hopper 22 through the blanking channel 20 can freely slide to the blanking port 23 due to gravity, avoiding the accumulation of soil inside the storage box 19 and the blanking hoppers 22. The setting of the blanking component enables the vertical rod 28 to continuously swing back and forth in both the horizontal and vertical directions, and when swinging in the horizontal and vertical directions, it can drive the two blanking hoppers 22 to move, avoiding the pause of the blanking hoppers 22 during the plastic film covering process, so as to prevent excessive soil from falling in a certain area and ensuring the uniformity of the soil pressing belt.

[0036] Specifically, as Figure 1 , Figure 2 and Figure 3 shown, the fixing frame 2 is provided with moving wheels 4 and side pressure wheels 8 that cooperate with the plowshare 12. A traction frame 3 is fixedly connected to one side of the vehicle frame 1 away from the soil covering mechanism. Preferably, the moving wheels 4 are provided with anti-slip protrusions to avoid difficulty in moving in areas with relatively soft soil. At the same time, the side pressure wheels 8 should be arranged in cooperation with the plowshare 12, preferably four. When covering the plastic film on two side-by-side ridges, the two sides of the plastic film on the two ridges can be simultaneously pressed tightly by the four side pressure wheels 8, facilitating subsequent soil covering operations.

[0037] In summary, for the plastic film covering device for daylily planting provided in this embodiment, when in use, first wind the plastic film on the winding roller 5, unfold the plastic film so that it bypasses the roller 6 and extends to the land outside the plowshare 12. Fix one end of the plastic film by covering it with soil. Connect the traction mechanism through the traction frame 3 to drive the overall movement of the plastic film covering device. Level the land to be covered with the plastic film through the flattening roller 7. As the plastic film covering device moves as a whole, the plastic film gradually unfolds and covers. Press the two sides of the plastic film through the side pressure wheels 8. At the same time, the plowshare 12 is embedded in the soil to turn up the soil on both sides of the plastic film. The plowshare 12 in the middle part of the vehicle frame 1 covers the plastic film on both sides. The soil turned up on the side of the plowshare 12 on both sides of the vehicle frame 1 close to the side pressure wheels 8 covers the outside of the plastic film. Meanwhile, the soil turned up on the side of the plowshare 12 on both sides of the vehicle frame 1 close to the receiving plate 17 is pushed onto the receiving plate 17 and gradually accumulates, and finally enters the storage box 19 through the conveyor belt 15 and the conveying channel 18. The soil in the storage box 19 enters the hopper 22 through the feeding channel 20 and falls to the plastic film through the feeding port 23 to form a soil pressing belt. Drive the connecting rod 34 to rotate through the driving motor 33, thereby driving the vertical rod 28 to swing. Due to the limitation of the sliding sleeve 27 and the second slide rail 26, the vertical rod 28 makes a reciprocating swing in the vertical direction and the horizontal direction and always remains vertical during the movement process, thereby driving the cross bar 29 and the two support rods 30 to move synchronously with the vertical rod 28. The relative movement between the limiting rod 31 and the third slide rail 25 causes the two hoppers 22 to reciprocate on the first slide rail 21. Cooperating with the overall movement of the plastic film covering device, the soil falling on the plastic film forms an S-shaped soil pressing belt.

[0038] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
