Abstract
Description
Technical Field
[0001] The utility model relates to a film punching mechanism for a rice film mulching transplanter which can be quickly disassembled and assembled, and belongs to the technical field of film punching mechanisms for rice film mulching transplanters. Background Technique
[0002] The rice film mulching transplanting cultivation method has the advantages of water saving, moisture preservation, temperature increase, fertilizer reduction, weed suppression, quality improvement and yield increase. And the transplanting quality of the rice film mulching transplanter is the key factor affecting the actual yield of rice. At present, in the rice film mulching operation on the market, there are mainly three forms of film opening knives: one is to directly use the seedling needle to punch holes in the film while transplanting seedlings; the second is to install a hole opening knife on the push rod of the transplanting arm of the transplanter; the third is to weld (install) a hole opening knife on the seedling needle of the transplanting arm of the transplanter. The above three hole opening mechanisms have the following problems: the hole opening knife damages the seedlings; the hole opening position is not accurate enough; it is easy to clamp the seedlings between the hole opening knife and the seedling needle. Due to these deficiencies, the seedling missing rate is relatively high during the transplanting process, and the survival rate of the seedlings is reduced, which is not conducive to the popularization of the rice film mulching planting method. Summary of the Invention
[0003] The purpose of the utility model is to solve the problems existing in the above-mentioned prior art, and further provide a film punching mechanism for a rice film mulching transplanter which can be quickly disassembled and assembled.
[0004] The purpose of the utility model is realized by the following technical solutions:
[0005] A film punching mechanism for a rice film mulching transplanter which can be quickly disassembled and assembled includes a floating boat adjusting frame, an extending end of a transplanting part transmission shaft and a transplanting part of a high-speed transplanter. It also includes a tool rest, a hole opening knife, a bolt pair, an upper clamping plate, a connecting rod one, a cam, a rotating shaft sleeve, a lower clamping plate, a tool rest rotating shaft and a connecting rod two. The floating boat adjusting frame is arranged at the lower part of the transplanting part of the high-speed transplanter. The extending end of the transplanting part transmission shaft is arranged on the transplanting part of the high-speed transplanter. The cam is installed at the end of the extending end of the transplanting part transmission shaft. The upper clamping plate is arranged at the upper part of the floating boat adjusting frame. The lower clamping plate is arranged at the lower part of the floating boat adjusting frame. The upper clamping plate and the lower clamping plate are fixedly connected by the bolt pair. The rotating shaft sleeve is fixedly connected with the lower clamping plate. The tool rest rotating shaft is rotatably connected with the rotating shaft sleeve. One end of the tool rest is fixedly connected with the tool rest rotating shaft. The other end of the tool rest is fixed with a hole opening knife. One end of the connecting rod two is fixedly connected with the tool rest rotating shaft. The other end of the connecting rod two is hinged with one end of the connecting rod one. The other end of the connecting rod one is hinged with the cam.
[0006] Advantages of the utility model:
[0007] The hole-opening mechanism of the present utility model realizes rapid disassembly and rapid installation. Its cam has an accurate fixed position, and the shape and length of the hole-opening knife are appropriately selected, which can accurately cut through the plastic film before the seedlings are inserted into the soil, ensure the effective insertion of the roots of the seedlings into the soil, and at the same time avoid the situation of seedling clamping by the seedling needles and the insertion of the roots of some seedlings on the plastic film. It effectively solves the major problems such as seedling clamping, seedling scratching, seedling breaking, and inaccurate hole opening that occur during the process of rice film-covering transplanting, greatly reduces the seedling supplement rate after transplanting (less than 5%), can significantly improve the film-covering transplanting efficiency and transplanting quality, ensure that the seedling survival rate reaches more than 95%, and thus enables the transplanting rate of rice film-covering transplanting to meet the national standards, making the popularization and application more convenient, and helping the rice film-covering cultivation method to achieve the goal of increasing production and income by more than 15%.
[0008] The present utility model is not limited to the application of hole-opening and transplanting on the film in rice film-covering operations, but can also be widely applied to the corresponding devices for film-covering cultivation of various crops such as vegetables, fruits, wheat, corn, soybeans, and flowers, ensuring the quality of film-covering transplanting.
