DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely explain the technical solutions in the embodiments of the utility model. It should be noted that the embodiments and features in the embodiments of the utility model can be combined with each other without conflict, and the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0024] See also Figure 1-4 The present embodiment is described as a seedling pressing and film covering device suitable for the furrow sowing technology of winter wheat in cold regions, which comprises a plurality of seedling pressing and film covering machine units 2 connected side by side, wherein the seedling pressing and film covering machine units 2 comprise a seedling pressing wheel 3, a frame 4, a ground film reel 5 and a ground film pressing wheel 6, wherein the seedling pressing wheel 3 is rotatably arranged at the front end of the frame 4, the ground film reel 5 is rotatably arranged at the lower middle part of the frame 4, and the ground film pressing wheel 6 is rotatably arranged at the lower tail end of the frame 4. In the present embodiment, by arranging a plurality of seedling pressing and film covering machine units 2 connected side by side, film covering of furrow sowing of wheat is achieved, and the device can achieve film covering operations of different ridge distances by changing the distance between two seedling pressing and film covering machine units 2, and can improve the film covering operation efficiency by adapting a corresponding number of seedling pressing and film covering machine units 2 according to the power size of the power part.

[0025] In this embodiment, a pressure roller is arranged below the mulch film reel 5, and the pressure roller is rotatably connected to the bottom of the first connecting frame. The pressure roller 5 is used to horizontally guide the mulch film 9 of the mulch film reel 5 to cover the wheat seedlings to achieve film covering.

[0026] In this embodiment, the power part can be a traction tractor, and human power or animal husbandry power can also be used as the power part in mountainous areas.

[0027] In this embodiment, the central axes of the seedling pressing wheel 3, the mulch reel 5 and the mulch pressing wheel 6 are on the same straight line.

[0028] In this embodiment, the bottom of the middle part of the frame 4 is connected to a first connecting frame, the ground film reel 5 is rotatably arranged in the middle part of the first connecting frame, the bottom of the tail end of the frame 4 is connected to a second connecting frame, and the ground film pressing wheel 6 is rotatably arranged at the bottom of the second connecting frame.

[0029] The second connecting frames on both sides of the ground film pressing wheel 6 described in this embodiment are rotatably connected with connecting arms 10, one end of the connecting arm 10 is rotatably connected to the second connecting frame, and the other end is connected to a film pressing sheet 7, which is used for film pressing and is made of a stainless steel pressing sheet and is connected to the rotatable connecting arm 10 to achieve an angle adjustment function. When film pressing is not needed, the connecting arm 10 can be parallel to the ground to facilitate the walking of the unit. When pressing the film, adjusting the angle of the connecting arm 10 can control the depth of the film pressing of the film pressing sheet 7.

[0030] In this embodiment, a connecting ring 11 is provided in the mulch pressing wheel 6, and a plurality of steel needles 12 are evenly spaced along the circumferential direction on the outer side of the connecting ring 11. Through holes matching the steel needles 12 are spaced along the circumferential direction on the outer surface of the mulch pressing wheel 6. One end of the steel needle 12 is rotatably connected to the connecting ring 11, and the other end is telescopically matched with the through hole. When the connecting ring 11 rotates counterclockwise, one end of the steel needle 12 shrinks into the mulch pressing wheel 6 through the through hole, and when the connecting ring 11 rotates clockwise, one end of the steel needle 12 extends out of the mulch pressing wheel 6 through the through hole. By providing a connecting ring and a telescopic steel needle 12 in the mulch pressing wheel 6, the mulch 9 can be punctured and punched while the mulch is being covered and pressed. There is no need to purchase mulch 9 with special holes, which saves costs. Piercing the mulch 9 helps air flow, and collects snow water at the root zone of winter wheat after the snow melts in spring, thereby ensuring a large amount of water demand during the greening period of winter wheat.

[0031] A knob is provided on one side surface of the ground film pressing wheel 6 in this embodiment, and the knob drives the rotation of the connecting ring 11. The connection method and driving method of the knob and the connecting ring 11 in this embodiment are both existing technologies and are not described here.

[0032] In this embodiment, the frames 4 of two adjacent seedling pressing and film covering machine units 2 are connected via a unit connecting device 8 .

[0033] In this embodiment, a power part connecting device 1 is provided at one end of the frame 4 of the seedling pressing and film covering machine monomer 2 located in the middle position. When the number of the seedling pressing and film covering machine monomers 2 is an even number, the power part connecting device 1 can be connected to the monomer connecting device 8 between the two seedling pressing and film covering machine monomers 2 located in the middle position. When the number of the seedling pressing and film covering machine monomers 2 is an odd number, the power part connecting device 1 can be connected to the frame 4 of the seedling pressing and film covering machine monomer 2 located in the middle position.

[0034] The seedling pressing wheel 3 described in this embodiment can press down the winter wheat seedlings with a plant height of about 10-15 cm, and then the ground film 9 on the ground film reel 5 can be covered on the flattened wheat seedlings under the guidance of the pressing roller 5. When the ground film pressing wheel 6 presses the ground film 9 on the wheat seedlings, the steel needles 12 extended from the ground film pressing wheel 6 puncture and punch holes in the ground film 9, and the film pressing sheets 7 on both sides of the ground film pressing wheel 6 press the ground film 9 into the ground.

[0035] In this embodiment, when the seedlings are not pressed evenly or the film pressing depth is insufficient, a counterweight can be appropriately added to the counterweight area 13 of the frame 4.

[0036] The embodiments of the utility model disclosed above are only used to help explain the utility model. The embodiments do not describe all the details in detail, nor do they limit the utility model to the specific implementation methods described. According to the content of this specification, many modifications and changes can be made. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the utility model, so that technicians in the relevant technical field can well understand and use the utility model.
