Description

Technical Field

[0001] The utility model relates to the technical field of tobacco planting equipment, and in particular to a movable plastic film mulching device for tobacco planting. Background Technique

[0002] When transplanting tobacco seedlings, the seedlings are generally small and have weak resistance to the external environment. Therefore, in order to provide heat preservation, moisture preservation and soil moisture preservation for the tobacco seedlings during planting, plastic film mulching is usually required when transplanting tobacco. In the prior art, the method of laying plastic film on the tobacco ridges is usually manual or by using a simple film mulching machine. For manual laying, two people are required to carry a large roll of plastic film on both sides of the tobacco ridge and lay it while moving, which is time-consuming and laborious and greatly increases the labor cost. And for the existing simple film mulching machine, fine adjustment still needs to be carried out manually after the plastic film is laid to avoid uneven laying of the plastic film or loose covering of the ridge body, thus reducing the efficiency. At the same time, after the plastic film is laid, holes also need to be opened on the ridge surface to facilitate the transplanting of tobacco seedlings.

[0003] During the process of laying the plastic film, due to the thin and light plastic film, wrinkles are easily generated or it is easily blown over by the wind, making the plastic film laid on the ridge uneven, thus affecting the laying effect of the plastic film. In addition, the existing method of opening holes in the tobacco plastic film is relatively rough. Generally, farmers use hard objects such as hoes and branches to pierce the plastic film. This way of opening holes will cause the opening positions on the tobacco ridge to be asymmetric, affecting the planting spacing of tobacco, and the hole sizes are different, affecting the growth uniformity of tobacco seedlings, and even causing the plastic film to rupture.

[0023] See Figures 1 to 4 As shown, the present utility model provides a movable plastic film covering device for tobacco planting. The same as the prior art, it includes a frame-shaped rack, a rotating shaft 2, a support rod 15, a traveling wheel 3, a punching wheel 4, and a plastic film mounting rack 14. The frame-shaped rack includes a relatively arranged first end 11, a second end 12, and a third end 13 perpendicular to the first end 11 and the second end 12. One end of the plastic film mounting rack 14 is fixedly arranged at the middle position of the first end 11, and the other end of the plastic film mounting rack 14 is provided with a plastic film 7. The support rod 15 includes a fixed section 151 and a telescopic section 152. The telescopic section 152 is telescopically connected to the fixed section 151. The fixed section 151 is fixedly connected to the bottom surface of the first end 11. The other end of the telescopic section 152 is provided with a connecting pipe 153. A through hole is provided in the middle of the connecting pipe 153. After the rotating shaft 2 passes through the through hole, it is respectively connected to the traveling wheel 3 and the punching wheel 4, and the punching wheel 4 is arranged inside the first end 11, and the traveling wheel 3 is arranged outside the first end 11. At the bottom of the second end 12, the support rod 15, the traveling wheel 3, and the punching wheel 4 are symmetrically arranged with respect to the center axis of the first end 11 and the second end 12. Different from the prior art, it further includes:

[0024] A soil covering shovel 5, the soil covering shovel 5 is arranged at one end of a first telescopic support rod, and the other ends of the two first telescopic support rods are fixedly arranged at the bottoms of the first end 11 and the second end 12, and the two soil covering shovels 5 are symmetrically arranged;

[0025] The plastic film guiding device 6 is arranged between the soil covering shovel 5 and the plastic film mounting frame 14. The plastic film guiding device 6 includes a second telescopic rod, a third telescopic rod, a fixed platform 63, a telescopic plate 64, a roller 65 and a guiding plate 66. The guiding plate 66 is arranged inside the fixed platform 63. The two fixed platforms 63 are telescopically connected together through the telescopic plate 64. A third telescopic rod is fixedly arranged on the side surface of the fixed platform 63. The third telescopic rod can drive the fixed platform 63 to perform telescopic movement to adjust the relative positions of the two fixed platforms 63. The other end of the third telescopic rod is connected to the second telescopic rod. The guiding plate 66 is provided with guiding holes 661. The guiding holes 661 are divided into horizontal holes and inclined holes. The horizontal holes are flush with the plastic film 7, and the included angle between the inclined holes and the horizontal holes is between 140° and 160°.

[0026] The traveling wheels 3 and the punching wheels 4 arranged at the bottoms of the first end 11 and the second end 12 are coaxially arranged together through a rotating shaft 2. In addition, the punching wheel 4 is detachably connected to the rotating shaft 2 because the punching function needs to be adjusted in real time according to requirements to cope with the situation that some places need punching when covering the film, while some places do not need punching.

[0027] During the actual use process, the plastic film 7 is passed through the guiding holes 661, and the part passing through the guiding holes 661 is attached to the tobacco ridge. Then, after the machine is connected to the first end 11, the movable plastic film 7 covering device for tobacco planting is towed forward. When the device moves forward, the plastic film 7 can be kept flat under the action of the guiding holes 661, and the guiding holes 661 can guide the plastic film 7 to the ground to prevent wrinkles from appearing on the ground during the laying process. Then the soil covering shovel 5 can continuously shovel up the soil on the side of the tobacco ridge, and the shoveled soil can form an eight-shaped diversion channel, and finally flow to the edge of the plastic film 7 from the small opening end of the eight-shaped channel to press the plastic film 7. At this time, the plastic film 7 will roll under the action of the soil compaction force, so as to carry out the continuous laying process of the plastic film 7. When the ground nail wheel moves to the soil covered with the plastic film 7, the ground nail wheel can open the holes on the surface of the plastic film 7.

[0028] During the above laying process, in order to ensure that the movable plastic film 7 covering device for tobacco planting can move smoothly on the uneven ground, the support rod 15 is set to be telescopic. When it is necessary to adapt to plastic films 7 of different widths, by controlling the device to adjust the third telescopic rod, the distance between the two fixed platforms 63 can be adjusted, so as to cope with plastic films 7 of different widths. In addition, although the height of the tobacco ridges is unified according to the planting specifications of the tobacco industry, due to manual reasons, the heights of the tobacco ridges in different regions are different. In order to cope with tobacco ridges of different heights, the third telescopic rod can be adjusted in height under the control of the control device.

[0029] During the rolling process of the plastic film 7, when the included angle between the inclined hole and the horizontal hole is 150°, the plastic film 7 can be smoothly guided onto the tobacco ridge, thus avoiding the problem of the plastic film 7 being wrinkled.

[0030] As an optimization, in order to keep plastic films 7 of different sizes always in the middle position of the frame-type rack, through holes are provided on the plastic film mounting rack 14. A lead screw 8 passes through the middle of the through holes. The plastic film 7 is arranged on the lead screw 8. An adjusting knob 81 is arranged on the lead screw 8. Rotating the adjusting knob 81 makes the lead screw 8 rotate, so as to adjust the position of the plastic film 7 left and right.

[0031] As an optimization, a traction plate 131 is arranged on the surface of the first end 11. Through the traction plate 131, the connection between the movable plastic film 7 covering device for tobacco planting and an external power device can be realized more conveniently.

[0032] As an optimization, it further includes a land pressing device 9. The land pressing device 9 is arranged between the soil covering shovel 5 and the punching wheel 4; the land pressing device 9 includes a screw 91, a connecting rod 92, a pressing wheel 93 and a limiting frame. The pressing wheel 93 is arranged inside the limiting frame. One end of the connecting rod 92 is fixedly connected to the bottom of the frame-type rack 1. A threaded hole is provided at the other end of the connecting rod 92. The side surface of the limiting frame is connected to the connecting rod 92 through the screw 91.

[0033] That is to say, after the plastic film 7 is laid, the movable plastic film covering device for tobacco planting provided by the present invention can automatically compact the plastic film 7, reducing the need for manual compaction operation. Otherwise, it is very easy for the wind to blow the plastic film 7 over when it is windy.

[0034] For the sake of description, relative space terms such as "above...", "over...", "on the upper surface of...", "upper" etc. can be used here to describe the spatial position relationship between a device or feature shown in the figure and other devices or features. It should be understood that relative space terms are intended to include different orientations in use or operation in addition to the orientation of the device described in the figure. For example, if the device in the attached drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will be positioned as "below other devices or structures" or "under other devices or structures" afterwards. Thus, the exemplary term "above..." can include two orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding explanations are made for the relative space descriptions used here.

[0035] In addition, it should be noted that using words such as "first", "second" etc. to limit components is only for the convenience of differentiating the corresponding components. Without additional statements, the above words have no special meanings, so they cannot be understood as limiting the protection scope of the present utility model.

[0036] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
