Description

Technical Field

[0001] The utility model relates to the technical field of drip irrigation pipe laying, in particular to a hanging drip irrigation pipe laying device. Background Art

[0002] Drip irrigation is a water-saving farmland irrigation technology. This technology mainly supplies pressurized water to the soil near the crop roots in small flow rates, evenly, and accurately through a pipeline system and emitters installed on the end-stage pipeline to meet the irrigation requirements for the normal growth of crops. In actual use, the drip irrigation pipe needs to be buried in the land at a certain depth. At present, the drip irrigation pipe laying device for laying the drip irrigation pipe into the land mainly includes a frame, as well as a reel, a soil cutting knife, and a soil covering device provided on the frame. When working: the drip irrigation pipe is pulled out from the drip irrigation pipe reel, guided by a guiding member and then enters the groove opened by the soil cutting knife, and the drip irrigation pipe is buried by the soil covering device. However, due to the different ground undulation heights, it is easy to cause inconsistent soil covering thickness, that is, inconsistent laying depth of the drip irrigation pipe. Moreover, when laying, the tension of the drip irrigation pipe cannot be understood in real time, and the drip irrigation pipe is easily broken, which affects the drip irrigation effect and increases the maintenance and replacement costs. The utility model patent with the authorization announcement number of CN215074442U discloses a drip irrigation pipe laying device, including a frame, and a reel installed on the frame for carrying the drip irrigation pipe. An installation pipe is provided on the frame, which has an input end facing the reel for the drip irrigation pipe to penetrate into, and an output end facing the ground for the drip irrigation pipe inside the pipe to penetrate out; a soil cutting knife and a soil covering device are provided at a position of the installation pipe close to the output end, and a first elastic member is provided between the installation pipe and the soil covering device, which effectively improves the problem of uneven soil covering of the drip irrigation pipe and can improve the consistency of the laying depth of the drip irrigation pipe. However, this device cannot measure the tension of the drip irrigation pipe during laying, and can only ensure the stability of the drip irrigation pipe laying by controlling the forward speed of the tractor by the tractor operator, which has relatively high requirements for the experience and technology of the tractor operator. Summary of the Invention

Specific implementation manner

[0017] The present utility model will be further described below in conjunction with the accompanying drawings:

[0018] As Figure 1 , Figure 2 and Figure 3 shown, a suspension type drip irrigation pipe laying device includes a suspension bracket 1 and a reel 2 arranged on the suspension bracket 1. The suspension bracket 1 is connected to a tractor. The main body of the suspension bracket 1 is L-shaped. A Y-shaped bracket is fixedly installed at the top of the suspension bracket 1. The reel 2 is rotatably installed on the Y-shaped bracket through a shaft. The drip irrigation pipe 3 is wound around the reel 2. When laying, the reel 2 rotates on the Y-shaped bracket under the pull of the drip irrigation pipe 3. In a preferred embodiment, a rotary damper is arranged on one side of the reel 2. The rotary damper is used to adjust the damping of the rotation of the reel 2, and the rotary damping of the reel 2 can be adjusted according to the forward speed of the tractor to ensure the smoothness of the laying of the drip irrigation pipe 3. Of course, the reel 2 can also be installed on the Y-shaped bracket through a damping shaft, which is convenient for damping adjustment.

[0019] The ditch opening component 4 is adjustably arranged at the bottom of the cantilever end of the suspension bracket 1. The ditch opening component 4 includes a connecting rod 40 connected to the suspension bracket 1 by bolts, a ditch opener 41 fixedly installed at the bottom of the connecting rod 40, and a diagonal brace 42 connected between the connecting rod 40 and the suspension bracket 1. The diagonal brace 42 improves the installation stability of the connecting rod 40. A plurality of mounting holes are vertically arranged on the connecting rod 40. During operation, the bolts are adjusted and installed in different mounting holes according to the ditch opening depth to achieve height adjustment. A third roller 43 is rotatably installed inside the ditch opener 41 through a pin shaft. The drip irrigation pipe 3 bypasses the outside of the third roller 43 and is laid in the ditch opened by the ditch opening component 4.

[0020] At the end of the ditch-opening component 4, a soil-covering component 5 is elastically arranged. The soil-covering component 5 includes a support shaft 50 rotatably installed on the ditch opener 41, a soil-covering member 51 fixedly arranged on the support shaft 50 by welding, and a spring 52 arranged between the soil-covering member 51 and the ditch opener 41. Under the action of the spring 52, the soil-covering member 51 can be adaptively adjusted along with the shape of the ground surface. When the ground surface undulates greatly, the soil-covering member 51 tilts upward, but under the pulling of the spring 52, the tilting height is limited, ensuring the uniformity of soil covering. An opening is arranged at the middle position of the end of the soil-covering member 51, and the width of the opening is greater than the diameter of the drip irrigation pipe 3. When there is less soil, it can preferentially ensure that the soil is covered directly above the drip irrigation pipe 3.

[0021] A tension detection component 6 is arranged on the ditch-opening component 4. One end of the drip irrigation pipe 3 passes through the tension detection component 6 and the ditch-opening component 4 and is laid in the ditch opened by the ditch-opening component 4, and the soil-covering component 5 covers the laid drip irrigation pipe 3 with soil. The tension detection component 6 includes a fixed seat 60 fixedly installed on the connecting rod 40, a first roller 61 rotatably installed on the fixed seat 60 through a rotating shaft, a pressure sensor 62 fixedly installed on the fixed seat 60 through a fastener, and a second roller 63 rotatably installed on the pressure sensor 62 through a bracket. The drip irrigation pipe 3 bypasses the first roller 61 and the second roller 62 in sequence and is then laid underground through the third roller 43. The pressure sensor 62 measures the laying tension of the drip irrigation pipe 3. When the forward speed of the tractor is fast and the rotating speed of the reel 2 is slow, the drip irrigation pipe 3 presses down on the second roller 62, causing the pressure measured by the pressure sensor 62 to increase, and it is intuitively reflected to the tractor operator through the controller and display arranged in the tractor cab; when the forward speed of the tractor is slow and the rotating speed of the reel 2 is fast, the force of the drip irrigation pipe 3 pressing down on the second roller 62 is small, causing the pressure measured by the pressure sensor 62 to be small, and the operator controls the vehicle speed according to the pressure value measured by the pressure sensor 62.

[0022] A restraint 7 is fixedly arranged on the suspension bracket 1 and / or the ditch-opening component 4 through fasteners, and the drip irrigation pipe 3 passes through the restraint 7, and the restraint 7 restricts the position of the drip irrigation pipe 3.

[0023] The above embodiments are only several descriptions of the concept and implementation of the present invention, and do not limit it. Under the concept of the present invention, the technical solutions without substantial transformation are still within the protection scope.
