[0002] In recent years, with the acceleration of China's agricultural modernization process, agricultural water-saving irrigation technology has been widely promoted. However, despite the significant advantages of water-saving irrigation technology in theory, it still faces many challenges in practical application.
[0003] China has vast arable land, and the terrain is complex and diverse, which makes the laying work of drip irrigation tape more complex and difficult. At present, there are few mechanical equipment for laying drip irrigation tape on the market, and the degree of mechanization is low, which leads to low work efficiency.
[0004] One of the core components of the drip irrigation system is the low-pressure pipeline, i.e. drip irrigation tape or drip irrigation pipe. Before carrying out drip irrigation work, it is necessary to lay the drip irrigation tape first. There are mainly two ways to lay the drip irrigation tape: surface laying and shallow burying. The traditional laying method usually relies on a laying machine tool driven by a tractor. The operator needs to manually hold the free end of the drip irrigation tape, wait for the machine to travel a certain distance and be pressed under the action of soil gravity, so as to smoothly carry out the laying work.
[0005] However, this traditional method has obvious shortcomings when replacing the drip irrigation tape turntable. Because the vehicle cannot stop in time, the staff need to pay attention to the number on the drip irrigation tape turntable at all times. Once the drip irrigation tape is about to run out, it needs to be replaced immediately. This process not only takes time and effort, but also needs to pass the drip irrigation tape through each device on the rack again, increasing the workload and time cost.
[0006] In addition, even if the situation that the drip irrigation tape is about to run out is observed, it also needs to be replaced in time. After replacement, a large amount of excess will be left on the drip irrigation tape, and the staff need to slowly start the vehicle to pull the excess. This process is also time-consuming and laborious, and is easy to cause waste and loss of drip irrigation tape.
[0007] In summary, the existing drip irrigation tape laying and replacement method has problems such as low efficiency, complicated operation and resource waste, and an efficient and convenient solution is urgently needed. UTILITY MODEL CONTENT

When designing, the horizontal height of the lower guide roller 18 is higher than the horizontal height of the upper end of the plow column 3. A guide groove corresponding to the width of the drip irrigation belt is arranged on the two guide rollers 18, so that the two guide rollers 18 can effectively guide the direction of the drip irrigation belt, and ensure that the drip irrigation belt can be accurately laid on the predetermined position. The two guide rollers 18 are arranged in parallel on the upper and lower sides, and cooperate with the guide groove, so as to enhance the stability of the guide roller 18 and effectively prevent the guide roller 18 from tilting or deviating during the guiding process. When manufacturing, the above-mentioned plow column 3 is arranged on the rack 1 behind the guide roller 18, and the column body of the plow column 3 is a hollow structure. The plow column 3 is fixed on the rack 1 in the vertical direction, and a furrowing piece is arranged on the front end side wall at the bottom of the plow column 3. A guide outlet for guiding the drip irrigation belt is arranged on the pipe body behind the furrowing piece. The double disc coverter 4 is installed on the plow column 3 above the guide outlet.

[0035] When using, the drip irrigation belt installed on the drip irrigation belt rotating wheel frame 2 passes through the guide block 20 of the locking mechanism 5, then passes through the deflection roller 7, and then passes through the uppermost positioning guide roller 8 and the corresponding buffer guide roller 13, and then passes through the second row of positioning guide rollers 8 and the corresponding buffer guide rollers 13, and then extends from the bottommost positioning guide roller 8 and passes out of the rack 1 through the guide roller 18 and extends along the plow column 3 to the lower side of the double disc coverter 4. In this way, when it is necessary to replace the drip irrigation belt, the pressure block 23 of the locking mechanism 5 is controlled to lock the drip irrigation belt on the guide block 20, and at the same time, the vehicle speed is slowed down. At this time, the drip irrigation belt is also slowly laid. Since the front belt body stops conveying, the weight of the drip irrigation belt laid in the rear will slowly reduce the belt body between the buffer device 9 and the plurality of positioning guide rollers 8 on the belt body buffer support 6, so as to ensure the continuous laying of the belt body. At this time, the worker can lock the newly replaced drip irrigation belt on one end of the remaining belt body through the buckle, and then open the air cylinder 22. The buffer device 9 will be reset, so that the laying work can continue. In this way, by arranging the locking mechanism 5 on the rack 1 and the buffer device 9 on the belt body buffer support 6, it is not necessary to stop the vehicle when replacing the drip irrigation belt rotating disc. The worker can prepare the new drip irrigation belt in advance, and quickly switch when the old belt is used up, which greatly improves the work efficiency.
[0036] The above embodiments are only used to illustrate the technical solutions of the present application, and are not limited thereto; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some or all of the technical features can be replaced by equivalent replacements; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
