Description

Technical Field

[0001] The utility model relates to the technical field of rice cultivation, in particular to a film covering device for rice seed cultivation. Background Art

[0002] In recent years, climate droughts have occurred frequently. In areas with reduced precipitation and water shortage, the application of rice film covering cultivation technology has achieved water-saving cultivation and fully tapped its production potential, which has promoted the development of water-saving agriculture and can effectively improve the social, economic and ecological benefits of arid areas. The rice film covering cultivation technology changes the natural state into a protected state and the flooded state into a moist state. It has significant effects such as saving water, fertilizer, seeds and labor, and shows huge comprehensive benefits of warming and early development, drought resistance and water saving, soil improvement and fertilizer conservation, oxygen isolation and weeding, labor and cost saving, disease and pest reduction, and increased production and efficiency.

[0003] Chinese patent CN212487628U proposes a film covering device for rice cultivation. The patent adjusts the width of the entire pressure roller surface by rotating and adjusting the curved pressure rollers at both ends of the straight pressure roller to move them away or closer, thereby meeting the needs of seedling beds of different widths. It is convenient and quick. At the same time, the curved pressure rollers fit the edge shape of the seedling bed better, making the film covering tighter.

[0004] However, this technical solution cannot adjust the height of the laminating roller when releasing the film. Once the driving wheel sinks deep into the soil due to the softness of the soil, the laminating roller will also touch the ground, resulting in failure to laminarize. Utility Model Content

[0005] The purpose of the present invention is to provide a film covering device for rice seed cultivation to solve the problems raised in the above background technology.

[0006] In view of the above problems, the technical solution proposed by the present invention is:

[0007] The cam is provided with a plurality of rollers, and the rollers are connected to the rollers by a plurality of rollers, and the rollers are connected to the rollers by a plurality of rollers.

[0008] As an optimal technical solution of the present invention, the threaded rod is driven to rotate by the driving member, so that the slider can move up or down, so that the reel and the covering shaft can move up and down synchronously, and can stop at any position within the adjustment distance. When the directional wheel sinks deeper due to the soft soil, the covering shaft can be adjusted to a suitable position in the above manner to ensure that it will not rub against the seedling bed. When holding the handle to push the device, the free end of the film is pulled out and ensure that the film is in contact with the covering shaft, and the free end of the film is fixed to the starting end of the seedling bed covering. When the device moves, the film can cover the seedling bed.

[0009] Specifically, the device can be used as an unpowered trolley, or a power drive component such as a gasoline engine can be added. The gasoline engine can be used to drive the device forward, and humans only need to steer the trolley, thereby reducing the workload on the staff.

[0010] As an optimal technical solution of the present invention, the driving member includes a worm wheel installed on the bottom surface of the threaded rod and a worm rotatably installed in the fixed block. The worm and the worm wheel are engaged and connected. A knob is provided on the outside of the fixed block, and the knob is connected to one end of the worm.

[0011] As an optimal technical solution of the present invention, a pair of limit frames are installed on the top of the fixed base, a limit rod is installed inside the limit frame, and a pair of limit blocks are installed on the outside of the connecting frame, and the limit blocks slide on the outside of the limit rod.

[0012] As a preferred technical solution of the present invention, the threaded rod is rotated by rotating the knob and cooperating with the worm gear and the worm, and the stability of the movement of the connecting frame is ensured by the limiting rod and the limiting block.

[0013] Specifically, the knob can be controlled manually or by an electric drive component such as a motor.

[0014] As a preferred technical solution of the present invention, the internal rotation connection of the slot has a limit axis.

[0015] As a preferred technical solution of the present invention, a limiting shaft is used to support the film passing through the slot so that the film does not come into contact with the slot, thereby ensuring that the film is not damaged.

[0016] As an optimal technical solution of the present invention, it also includes a soil covering mechanism, which includes a storage box installed on the top of the fixed base, and the storage box is located between the connecting frame and the handle. Dry soil is stored inside the storage box. The bottom of the storage box is connected to a pair of square tubes, and the top of the fixed base is provided with a pair of through holes, and the square tubes are located in the through holes.

[0017] As an optimal technical solution of the present invention, a pair of square tubes are rotatably connected with a connecting shaft, and the two ends of the connecting shaft are connected to the rotating shaft. A pair of soil retaining parts are installed on the outside of the connecting shaft, and the pair of soil retaining parts are respectively located in the pair of square tubes.

[0018] As a preferred technical solution of the present invention, the retaining member includes four groups of retaining plates of equal size, and the free ends of the retaining plates are arc-shaped, and the free ends of the retaining plates are in contact with the inner wall of the square tube.

[0019] As a preferred technical solution of the present invention, when the device moves, the directional wheel will drive the connecting shaft to rotate together, so that the soil retaining member rotates in the square tube, so that the dry soil falls out of the square tube in a fixed quantity and distance, and falls to both sides of the top of the film, thereby pressing the film and reducing the amount of dry soil used.

[0020] Compared with the prior art, the beneficial effect of the present invention is that the film covering device for rice seed cultivation drives the threaded rod to rotate through a driving member, so that the threaded rod can infinitely adjust the height of the reel and the film covering shaft, ensuring that the film covering shaft will not contact the seedling bed, so that the device can cover seedling beds with different softness.
