Description

Technical Field

[0001] The utility model relates to the technical field of film covering machines, in particular to a convenient film covering device for potato planting. Background Art

[0002] Potatoes contain 8-29% starch and protein, minerals, vitamins and other nutrients. They are high-yielding and widely adaptable, and have gradually become important food, vegetables, feed and industrial raw materials for humans. Nowadays, large-scale potato planting is gradually tending to be mechanized. Potato sprout blocks are planted mechanically. In order to increase potato yields, film covering technology has been introduced into the potato planting process. After the potato sprout blocks are planted, the surface is covered with film to make full use of light and heat resources, which can increase the surface soil temperature by 3-5 degrees Celsius, promote the growth of potato sprouts, promote germination and early fruiting; at the same time, it can also reduce water evaporation, improve the physical and chemical form of the soil, and improve nutrient utilization.

[0003] In large-scale potato planting enterprises, film covering is carried out by using film covering machines, which mainly include film covering components and soil covering components. The ground film is embedded in the film covering components. As the film covering machine moves, the ground film is gradually pulled out, and then the soil on both sides is pressed onto the ground film through the soil covering components. Mechanized operation reduces labor costs and improves work efficiency. However, there are certain problems when using the current film covering machines: the soil covering components cannot be stored, and when they are left stationary or moved, the film covering machine needs to be lifted and moved to avoid the tip of the soil covering component from scraping the ground and being worn.

[0004] To this end, the utility model provides a convenient film covering device for potato planting, which can avoid the problem of soil covering components scraping the ground during the transfer process. Utility Model Content

The mounting frames 7 are provided with external threaded sleeves 12 coaxial with the through holes, and a nut 13 matching the external threaded sleeve 12 is provided at the outer end of the insertion rod 8. A film coating roller 18 is provided on the frame 1 at a position obliquely below the mounting frames 7 on the side facing the wheel 2.

[0030] The specific use process of this embodiment is as follows:

[0031] When covering the film: the limit hole on the extension rod 11 corresponds to the socket 9 just above, the screw 10 is inserted into the limit hole and the socket 9, and then the nut is screwed on, so that the support 4 is vertical, the furrow opener 5 and the covering plate 6 are both against the ground, the roll of the ground film is placed between the two mounting frames 7, and the insertion rods 8 are inserted one by one. The insertion rods 8 are inserted into the roll, and the nut 13 is screwed on the external threaded sleeve 12, so that the ground film is embedded in the frame 1, and the protruding end of the ground film is pulled out and bypassed by the film covering roller 18 and pressed on the surface, and the film covering roller 18 is pressed against the ground surface. The ground film is limited to prevent the wheel 2 from rolling over the raised part of the ground film and tearing it. The frame 1 moves forward, the reel rotates continuously, and the ground film is continuously pulled out and laid on the ground surface, so that the laying of the ground film is convenient and fast. While the frame 1 moves forward, the furrow opener 5 opens the furrow, and the two sides of the ground film fall into the furrow, and the covering plate 6 is in an inverted eight-shaped shape, which will move the loose soil and press it on the ground film, so as to realize the pressing and fixing of the ground film, simplify the steps, and open the furrow first and then cover the soil, so that the two sides of the ground film are deeper in the soil, the compaction is tighter, and the ground film is more firm.

[0032] During transfer: remove the screw 10, deflect the support 4, so that the limit hole on the extension rod 11 corresponds to one of the sockets 9 on both sides, and then put the screw 10 in and tighten the nut. At this time, the support 4 remains horizontal, the furrow opener 5 and the covering plate 6 are away from the ground, and will not scratch the ground as the frame 1 is transferred, causing wear.

[0033] In this embodiment, two protective plates (not shown in the drawings) are symmetrically provided on the front and rear sides of the frame 1. When the tips of the furrow opener 5 and the covering plate 6 are facing upward, the protective plates are located above the tips of the two to prevent others from being accidentally stabbed and improve transportation safety.

[0034] In this embodiment, the spacing between the two covering plates 6 is greater than the spacing between the two furrow openers 5 and greater than the width of the ground film, ensuring that the soil separated by the furrow openers 5 on the side of the ground film can be pushed to the side of the ground film, that is, ensuring the tightness of the pressure covering on the side of the ground film.

[0035] Embodiment 2, the nut 13 is rotatably connected to the insertion rod 8, and a mounting ring 14 is inserted into the insertion hole 9, and a clamping plate 17 is fixed to the opposite ends of the two mounting rings 14, and a rubber pad is provided on the opposite side of the two clamping plates 17, and a limiting ring 15 is provided on the inner wall of the mounting ring 14, and a convex ring 16 cooperating with the limiting ring 15 is provided on the outer wall of the insertion rod 8, and friction damping is provided between the outer wall of the mounting ring 14 and the through hole, and between the insertion rod 8 and the nut 13; the insertion rod 8 is inserted into the through hole, and the convex ring 16 presses against the limiting ring 15 and moves toward the axial direction of the frame 1, and the limiting ring 15 drives the mounting ring 14 to move, and the limiting ring 15 drives the clamping plate 17 to move, so that the two clamping plates 17 firmly hold the two ends of the ground film roll, and under the action of friction damping, the flexibility of the roll deflection is reduced, to prevent the roll from rotating suddenly and causing the ground film to stack, resulting in loose and uneven laying of the ground film.

[0036] In this embodiment, the tightening direction of the nut 13 on the external threaded sleeve 12 is the same as the direction in which the ground film is pulled out from the reel, so as to prevent the nut 13 from loosening and causing the insertion rod 8 to fall off.

[0037] Embodiment 3, the vehicle frame 1 includes two main beams 101, and a plurality of bridges 102 are arranged between the two main beams 101. The bridges 102 and the main beams 101 are fixed by welding. A traction saddle 104 is arranged on the front bridge 102 for connecting with the front of the vehicle. A bridge frame 103 is arranged at the center of the lower end surface of the two main beams 101, and the vehicle is rotatably mounted on the bridge frame 103. The structure is simple and the production is convenient.

[0038] In embodiment 4, two film covering rollers 18 are provided and are symmetrically mounted on the frame 1 along the wheels 2, one to prevent the wheels 2 from pressing on the raised area of ​​the ground film and breaking the ground film, and the other to prevent the ground film from remaining stable before being covered with soil.
