Description

Technical Field

[0001] The utility model relates to a suspended ground film hole opening device for a rice film covering and transplanting machine, belonging to the technical field of ground film hole opening devices. Background Art

[0002] In recent years, rice mulching has gained widespread acceptance in the agricultural sector, boasting advantages such as water conservation, soil moisture conservation, weed control, fertilizer savings, and yield increases. The combined use of biodegradable mulch films and mulch transplanters has significantly benefited the healthy development of green organic agriculture. However, rice mulch transplanters, as a key production tool, have been hindered by technical difficulties in field operation, hindering their mass production and widespread adoption. The mulch film perforation mechanism in these transplanters is crucial, directly impacting the transplanting and survival rates of seedlings, and ultimately, the actual rice yield.

[0003] Currently, there are roughly the following types of mulch hole-piercing devices in the industry: one is to use seedling needles to punch holes in the mulch while transplanting; the second is to install a hole-piercing knife on the transplanter's planting arm push rod; the third is to weld (install) the hole-piercing knife on the transplanter's seedling needle; and the fourth is to weld the hole-piercing device to the floating mounting frame, using the extended shaft of the planting unit as the power source, and driving the paddle to drill holes through a connecting rod mechanism. These hole-piercing devices all have some problems to varying degrees: the first method performs hole-piercing and transplanting at the same time, which can cause inaccurate hole alignment and easily break the seedlings; the second method causes mud to get stuck between the seedling needle and the seedling sorter, and the hole-piercing knife can easily pull out the newly planted seedlings when the transplanting arm is raised; the third method causes the hole-piercing blade to be too close to the push rod, causing mud to get stuck, making it impossible for the push rod to complete the planting operation, and the hole-piercing knife can damage the seedlings when the seedling needle removes them; the fourth method uses welding, which is complex and requires professional installation. It is also difficult to dismantle, which not only damages the transplanter structure but also makes it impossible to restore the transplanter to its original state. If installed on user-owned transplanters, it is difficult to promote on a large scale. The above methods directly affect the transplanting rate of rice film-mulched transplanting and the operating efficiency of the transplanter. Summary of the Invention

[0004] The purpose of the utility model is to solve the problems existing in the above-mentioned prior art and further provide a hanging ground film hole opening device for a rice film mulching and transplanting machine.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] A suspended ground film hole opening device for a rice mulching transplanter comprises: a riding high-speed rice transplanter, a planting part, a planting part square beam, a planting arm transverse transmission shaft and a suspended ground film hole opening mechanism; the suspended ground film hole opening mechanism is mounted on the planting part square beam at the lower end of the planting part of the riding high-speed rice transplanter, and the planting arm transverse transmission shaft provides power to the suspended ground film hole opening mechanism, the suspended ground film hole opening mechanism comprises a left hanger, a square card, a rotating shaft, a right hanger, a hole opening knife mounting plate, a hole opening knife, a split positioning block, a cam, a connecting rod and a connecting rod ear plate; the suspended ground film hole opening mechanism The left hanger and the right hanger of the mechanism are respectively installed on the left and right sides below the square beam of the planting part, and the left hanger and the right hanger are fixed to the square beam of the planting part by square clips; the rotating shaft passes through the inner holes of the round tubes on the left hanger and the right hanger and can rotate in the inner holes of the round tubes, and a hole-punching knife mounting plate and a connecting rod ear plate are welded on the rotating shaft, and the hole-punching knife mounting plate is fixed with a bolt group. One end of the connecting rod is hinged on the connecting rod ear plate, and the other end of the connecting rod is connected to a cam, which is installed on the transverse transmission shaft of the planting arm, and the split positioning block is installed on the rotating shaft for transverse positioning of the rotating shaft.

[0007] Beneficial effects of the utility model:

[0008] The utility model features a hanging mulch film hole-punching device with accurate positioning, precise cam installation angle, appropriate adjustment of the connecting rod length, and appropriate selection of the hole-punching knife shape and length. This device can accurately perform synchronous hole-punching for rice transplanting, ensuring that the seedlings are accurately inserted into the holes in the mulch film cut by the hole-punching device. This effectively improves the transplanting rate of rice mulch film transplanting, with the transplanting rate even exceeding relevant national standards. The above solution can solve the problems of seedlings being clamped by needles and the roots of some seedlings being planted on the mulch film, avoiding the phenomenon of seedlings being broken or scratched, which often occurs during rice mulch film transplanting operations. This significantly improves the survival rate of seedlings and effectively reduces the rate of seedling replacement in the later stages of transplanting, reducing the replacement rate from the previous 30% to less than 5%.

[0009] Due to its structural characteristics, the suspended mulch film hole-opening device can adapt to the high-speed transplanting state in the field, significantly improving the operating efficiency and transplanting quality of the mulch film transplanter. The operating efficiency can reach 3-4 acres per hour, clearing the key technical obstacles for the mass production and wide application of mulch film transplanting machinery, and laying a solid foundation for degradable mulch film manufacturers to open up the domestic market and accelerate the development of green agriculture.

[0010] The utility model is not limited to the application of opening holes in the film for transplanting rice in rice film covering operations, but can also be widely used as a corresponding device for film covering planting of various types of crops such as vegetables, fruits, wheat, corn, soybeans, flowers, etc., and has high practical value.
