Description

Technical Field

[0001] This utility model relates to a device for fixing the drip irrigation tape of mulch film for turning around and starting a seeder. Background Technology

[0002] With the development of water-saving agricultural planting technology, especially in agricultural planting in arid areas of the north, the application of mulch film covering and drip irrigation technology has become very widespread. The laying of mulch film covering and drip irrigation tape is a very important part of the application of mulch film drip irrigation technology.

[0003] In current drip irrigation planting, the mulch covering and drip irrigation tape laying are almost entirely mechanized operations, meaning that mulch covering, drip irrigation tape laying and sowing are all done in one go by machinery.

[0004] In current operations involving mulching, drip irrigation tape laying, and sowing, the initial sowing and turning-around stages of the seeder, especially the turning-around stage, require cutting the drip irrigation tape and mulch film on the seeder before turning around and starting again. Currently, the drip irrigation tape and mulch film ends are manually lifted and held in place as the machine turns around. After the turn, the ends of the drip irrigation tape and mulch film are pressed down and fixed before the machine starts to operate normally. This process is not only labor-intensive and time-consuming, but also cannot guarantee the quality of the completed work.

[0005] CN215380345U discloses a cotton sowing initiation mulch film tube fixing device, which consists of a positioning pressure plate, a mulch film roll, and an adjusting buckle. Due to the design concept, this device has two problems: first, it cannot achieve good fixation to the ground in actual use, such as the need for manual pressing at the start to ensure that the device is not lifted by the seeder; second, in the case of multiple films, the winding of the mulch film, especially the need for manual intervention to cut the mulch film, is quite troublesome.

[0006] Therefore, a device for fixing mulch film and drip irrigation tape to seeders with less manual intervention, requiring only manual connection of the mulch film and drip irrigation tape to the device, and requiring no manual intervention when the seeder starts, has emerged. Summary of the Invention

[0007] The purpose of this invention is to provide a mulch film and drip irrigation tape fixing device for seeders that requires less manual intervention during operation, only the manual connection of the mulch film and drip irrigation tape to the device is needed, and the seeder can start without any manual intervention, and has a good fixing effect when turning around and starting.

[0008] The purpose of this utility model is achieved through the following structure: It includes a main frame (1-1), on which a scroll sleeve (2-3) and a scroll (2-1) are provided. The scroll sleeve (2-3) is a horizontally oriented circular tubular groove at the lower part of the main frame (1-1). The scroll (2-1) is a cylindrical rod disposed within the scroll sleeve (2-3) and can rotate within the scroll sleeve (2-3). The scroll (2-1) is equipped with a scroll drive mechanism. The device has protruding nail teeth (2-2) and a cutting device is provided parallel to the scroll (2-1). The cutting device includes a blade holder rod (3-1). The blade holder rod (3-1) is set on the main frame (1-1) or the scroll sleeve (2-3) through a slide rail mechanism (3-5) or a swing rod mechanism (3-6). A second return spring (3-3) is provided between the blade holder rod (3-1) and the main frame (1-1). A cutting blade (3-2) is axially provided at the lower part of the blade holder rod (3-1).

[0009] Furthermore, a second foot pedal (3-4) is provided on the aforementioned tool holder rod (3-1).

[0010] Furthermore, the aforementioned reel drive mechanism includes a transmission mechanism composed of a passive part (2-4) and an active part (2-5). The transmission mechanism composed of the passive part (2-4) and the active part (2-5) can be one of a gear transmission mechanism, a chain transmission mechanism, a belt transmission mechanism, or a transmission cable. A first return spring (2-9) is provided corresponding to the transmission mechanism. One end of the first return spring (2-9) is connected to the main frame (1-1), and the other end is connected to the passive part (2-4) or the reel (2-1) of the transmission mechanism. A drive handle (2-6) is provided on the active part (2-5), and a first locking mechanism (2-7) and a second locking mechanism (2-8) are provided on the drive handle (2-6) or the transmission mechanism.

[0011] Furthermore, the first locking mechanism (2-7) is preferably a latching mechanism, and the second locking mechanism (2-8) is a ratchet and pawl mechanism.

[0012] Furthermore, the cutting blade (3-2) described above is preferably a serrated blade.

[0013] Compared with the existing technology, the advantages of this utility model are: the fixing of the drip irrigation tape and the mulch film can be achieved with less manual labor, and manual intervention can be eliminated when turning, turning around or starting, which greatly improves the efficiency of operation.
