Description

Technical Field

[0001] The invention relates to a mulch film drip irrigation belt fixing device for a seeder to turn around and start. Background Art

[0002] With the development of agricultural water-saving planting technology, especially in agricultural planting in the northern arid areas, the application of mulch film covering and drip irrigation planting technology has been very widespread. Mud film covering and the laying of drip irrigation tapes are a very important link in the application of mulch film drip irrigation planting technology.

[0003] In the current mulch film drip irrigation planting, mulch film covering and drip tape laying are almost completely mechanized, that is, mulch film covering, drip tape laying and sowing are performed in one operation by mechanical machines.

[0004] In the current mulch covering, drip irrigation tape laying and sowing operations, in the initial sowing and field turning stages of the seeder, especially the field turning stage, it is necessary to cut off the drip irrigation tape and mulch film on the seeder, then turn around, and start again. During the turning, the drip irrigation tape and mulch film head are currently lifted manually as the locomotive turns around. After the turn is completed, the drip irrigation tape and mulch film head ends are pressed and fixed, and then the locomotive starts and enters normal operation. This process not only consumes manpower and time, but also the quality of the completed operation cannot be guaranteed.

[0005] CN215380345U discloses a cotton sowing starting ground film tube belt fixing device, which is composed of a positioning pressure plate, a ground film reel and an adjustment buckle. Due to the design concept, the device cannot be well fixed to the ground in actual use. For example, when starting, personnel still need to press to ensure that the device is not lifted up by the seed drill. Secondly, during operation, in the case of multiple films, when winding the ground film, especially the ground film needs manual intervention for cutting, the operation is more troublesome.

[0006] Therefore, a method with less manual intervention is required, and only the ground film and drip irrigation belt are manually connected to the device. No manual intervention is required when the seeder starts. A ground film drip irrigation belt fixing device for seeder turning around and starting with good fixing effect came into being. Summary of the invention

[0007] The purpose of the present invention is to provide a mulch film and drip irrigation belt fixing device for a seeder turning around and starting, which requires less manual intervention during operation and only requires manual connection of the mulch film and the drip irrigation belt to the device. When the seeder starts, no manual intervention is required at all and the fixing effect is good.

[0008] The object of the present invention is achieved by the following structure: comprising a main frame (1-1), a reel sleeve (2-3) and a reel (2-1) are arranged on the main frame (1-1), the reel sleeve (2-3) is a circular tubular groove in the horizontal direction of the lower part of the main frame (1-1), the reel (2-1) is arranged in a columnar rod body in the reel sleeve (2-3) and can rotate in the reel sleeve (2-3), the reel (2-1) is provided with a reel driving mechanism, and the reel (2-1) is provided with a reel driving mechanism. A protruding spike (2-2) is provided, and a cutting device is provided in parallel with the reel (2-1), the cutting device comprising a knife holder rod (3-1), the knife holder rod (3-1) being arranged on a main frame (1-1) or a reel sleeve (2-3) via a slide rail mechanism (3-5) or a swing lever mechanism (3-6), a second return spring (3-3) being provided between the knife holder rod (3-1) and the main frame (1-1), and a cutting knife (3-2) being axially provided at the lower part of the knife holder rod (3-1).

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