Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of infiltration irrigation, in particular to a device for laying a pipe network for underground infiltration irrigation based on capillary effect and a construction method. BACKGROUND

[0002] Infiltration irrigation is a water-saving irrigation technique that directly delivers water to the crop root layer through an underground pipe system. The core of this technique is to use soil capillary action to achieve uniform water distribution. However, the existing irrigation pipe laying equipment is generally single-pipe type, which cannot accurately guide the multi-layer structure of capillary infiltration composite materials. In particular, in areas with undulating terrain or dense obstacles, the traditional drag chain structure can easily cause pipe shaking and deviation, uneven burial depth, and layer folding, which affects the uniformity of water output and the infiltration efficiency of the system.

[0003] Therefore, a deep-buried infiltration irrigation pipe laying machine is disclosed in Chinese Patent No. CN116497890A. The machine sets a breaking component in front of the trenching and pipe laying assembly to break and loosen the shallow soil layer, thereby reducing the resistance when the assembly moves and ensuring the accuracy and depth consistency of the pipe laying.

[0004] However, during pipe laying, if there are stones or other hard obstacles in the soil, the breaking component cannot break them. Not only will the breaking component be damaged, but the supporting rods and pipes will also be damaged when the pipe laying assembly collides with the obstacles. This not only damages the equipment, but also prevents the pipes from being laid for infiltration irrigation. SUMMARY

[0007] Preferably, the sensing mechanism comprises a buffer assembly and a first transmission assembly; the buffer assembly is arranged on the rack, and the driving end of the rotary driving assembly is in transmission connection with the main rod through the first transmission assembly; when the rotation of the main rod is blocked, the torque transmitted by the rotary driving assembly through the first transmission assembly compresses the buffer assembly.

[0008] Preferably, the buffer assembly comprises a limiting ring, a mounting cylinder, an extension rod and a first elastic member; the mounting cylinder is arranged on the rack, and the mounting cylinder is provided with a pressure sensor; the limiting ring is in transmission connection with the first transmission assembly; the extension rod is slidingly arranged in the mounting cylinder, and the extension rod is connected with the limiting ring; and the first elastic member is sleeved on the extension rod, and the two ends of the first elastic member are respectively connected with the limiting ring and the mounting cylinder.

[0011] Preferably, the rack is provided with a mounting table and a lifting assembly for driving the mounting table to lift; the main rod is rotatably arranged on the mounting table, and the sensing mechanism is arranged on the mounting table.

[0012] Preferably, the rack is provided with a material roll for bearing the pipeline; the rack is provided with a mounting frame in transmission connection with the lifting assembly, and the pipeline on the material roll is connected with the mounting frame.

[0013] Preferably, the lifting assembly comprises a second rotary driver, a screw rod and a connecting frame; the second rotary driver is arranged on the rack, and the second rotary driver is used for driving the screw rod to rotate; the screw rod is rotatably arranged on the rack; the screw rod is in threaded connection with the connecting frame, and the connecting frame is connected with the mounting table.

[0014] Preferably, the rack is provided with a soil roller for compacting soil.

[0015] A construction method for laying an underground irrigation pipeline network, comprising the following steps: S1, starting the rotary driving assembly, the rotary driving assembly drives the main rod and the fork to rotate, and the soil is broken and treated; S2, burying the pipeline through the pipe laying mechanism; S3, when the sensing mechanism senses that the damping of the fork exceeds the threshold value, stopping the rotary driving assembly.

[0016] The beneficial effects of the present application compared with the prior art are: 1.

When the rotary driving assembly drives the main rod to rotate through the first transmission assembly, the first transmission assembly transmits the damping to the limiting ring, and the first elastic member is contracted under the action of the damping, until the elastic force of the first elastic member balances with the resistance of the fork rotation, the first transmission assembly transmits the torque to the main rod, and drives the fork to rotate at a constant speed. When the resistance of the fork rotation increases, the first transmission assembly transmits the damping to the limiting ring again, and drives the limiting ring to move upward, so as to further compress the first elastic member, until the elastic force of the first elastic member exceeds the resistance of the fork, the main rod and the fork continue to rotate. When the limiting ring contacts with the mounting cylinder, the elastic force of the first elastic member exceeds the threshold value, the pressure sensor detects the pressure, and feeds back the signal to the controller, the controller stops the driving of the first rotary driver, to avoid the problems of overloading of the first rotary driver, wear of the fork, scratch of the pipe and the like.

DETAILED DESCRIPTION

[0019] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Reference Figures 1-3 : Capillary effect based underground irrigation pipe network laying device, comprising a rack 1, a crushing mechanism 2, a sensing mechanism 3 and a pipe laying mechanism 4; the crushing mechanism 2 comprises a main rod 21 and a rotary drive assembly 22 for driving the main rod 21 to rotate, the main rod 21 is rotatably arranged on the rack 1, and a shift fork 211 is arranged on the main rod 21; the sensing mechanism 3 and the pipe laying mechanism 4 are arranged on the rack 1; the sensing mechanism 3 is used for sensing the resistance to rotation of the shift fork 211, and the pipe laying mechanism 4 is used for laying the pipe underground.

[0021] The present application realizes the function of sensing the resistance to rotation of the shift fork 211 when the pipe is laid in the crushed soil through the rack 1, the crushing mechanism 2 and the sensing mechanism 3, and the pipe laying action is stopped in time when the shift fork 211 is affected by the obstacle, so that the obstacle can be removed in time. While ensuring the pipe laying work, the cost loss caused by the obstacle is avoided. The problem of damage to the pipe and the equipment caused by the obstacle in the pipe laying process is solved. The rack 1 is provided with wheels 14 and a motor for driving the wheels 14 to rotate. The rotary drive assembly 22 comprises a first rotary driver 221, a support 222, a main shaft 223, a worm 224 and a worm wheel 225; the first rotary driver 221 and the support 222 are arranged on the rack 1, the main shaft 223 and the worm 224 are rotatably arranged on the support 222, the main shaft 223 is in transmission connection with the main rod 21, the worm wheel 225 is sleeved on the main shaft 223, the worm wheel 225 is in meshing connection with the worm 224, and the driving end of the first rotary driver 221 is in transmission connection with the worm 224. The rack 1 is provided with a controller for human-computer interaction, and the first rotary driver 221 is in electrical connection with the controller. In the working state, the rack 1 is moved by driving the wheels 14 to rotate through the motor. In the moving process of the rack 1, the controller sends a signal to the first rotary driver 221, the first rotary driver 221 drives the worm 224 to rotate after receiving the signal, the worm 224 drives the worm wheel 225 to rotate, and the worm wheel 225 drives the main shaft 223 to rotate. The main shaft 223 drives the main rod 21 to rotate, the main rod 21 drives the shift fork 211 to rotate, the soil is crushed through the shift fork 211, and the pipe laying mechanism 4 is facilitated to bury the pipe underground. The shift fork 211 rotating at the same time pushes away the obstacle in the soil, so that the obstacle in the soil does not hinder the pipe laying. When a larger obstacle is encountered, the rotation of the shift fork 211 cannot push away the obstacle, and the rotation of the shift fork 211 and the main rod 21 is blocked. When the sensing mechanism 3 detects that the resistance exceeds a threshold value, the driving of the rotary drive assembly 22 is stopped, so that the operator has enough time to process the obstacle, and the equipment and the pipe are prevented from being damaged due to the influence of the obstacle.

[0022] Reference Figure 1 and Figure 2The induction mechanism 3 comprises a buffer assembly 31 and a first transmission assembly 32; the buffer assembly 31 is arranged on the frame 1, and the driving end of the rotary driving assembly 22 is in transmission connection with the main rod 21 through the first transmission assembly 32; when the rotation of the main rod 21 is blocked, the torque transmitted by the rotary driving assembly 22 through the first transmission assembly 32 compresses the buffer assembly 31.

[0023] The buffer assembly 31 and the first transmission assembly 32 realize the function of damping the rotation and contraction of the fork 211. When the rotation of the fork 211 is blocked, the torque transmitted by the rotary driving assembly 22 through the first transmission assembly 32 compresses the buffer assembly 31, and at the same time, greater damping is transmitted to the main rod 21 and the fork 211. If the torque of the fork 211 is enough to push away the obstacle, after the obstacle is pushed away, the buffer assembly 31 is reset, and the torque of the fork 211 returns to the initial state. If the torque of the fork 211 still cannot push away the obstacle after increasing, when the compression amount of the buffer assembly 31 reaches the threshold value, the driving of the rotary driving assembly 22 is stopped. The torque of the fork 211 can be automatically adjusted according to the damping suffered by the fork 211, in normal conditions, low-power operation can be realized, when encountering an obstacle, the torque can be automatically increased to push away the obstacle. When the damping is too large, the work can be automatically stopped, and the cost loss is reduced.

[0024] With reference to Figures 2-5 , Figure 8 and Figure 9 : The buffer assembly 31 comprises a limiting ring 311, a mounting cylinder 312, a telescopic rod 313 and a first elastic member 314; the mounting cylinder 312 is arranged on the frame 1, and the mounting cylinder 312 is provided with a pressure sensor, and the limiting ring 311 is in transmission connection with the first transmission assembly 32; the telescopic rod 313 is slidably arranged in the mounting cylinder 312, and the telescopic rod 313 is connected with the limiting ring 311; the first elastic member 314 is sleeved on the telescopic rod 313, and two ends thereof are connected with the limiting ring 311 and the mounting cylinder 312 respectively.

[0025] The application realizes the function of automatically adjusting the driving force according to the damping suffered by the fork 211 through the limiting ring 311, the mounting cylinder 312, the telescopic rod 313 and the first elastic member 314. When the rotating driving assembly 22 drives the main rod 21 to rotate through the first transmission assembly 32, the first transmission assembly 32 transmits the damping to the limiting ring 311, and the first elastic member 314 is contracted under the damping until the elastic force of the first elastic member 314 is balanced with the resistance suffered by the fork 211 in rotation, the first transmission assembly 32 transmits the torque to the main rod 21, and pushes the fork 211 to rotate at a constant speed. When the resistance suffered by the fork 211 in rotation increases, the first transmission assembly 32 transmits the damping to the limiting ring 311 again, pushes the limiting ring 311 to move upwards, and further compresses the first elastic member 314, until the elastic force of the first elastic member 314 exceeds the resistance suffered by the fork 211, and the main rod 21 and the fork 211 continue to rotate. When the limiting ring 311 contacts with the mounting cylinder 312, the first elastic member 314 is contracted to the limit, the pressure sensor detects the pressure, and feedbacks the signal to the controller, the controller stops the driving of the first rotating driver 221, avoids the problems of overloading of the first rotating driver 221, abrasion of the fork 211 and scratch of the pipeline.

[0026] With reference to Figures 2-5 , Figure 8 and Figure 9 : The first transmission assembly 32 comprises a mounting plate 321 and a threaded sleeve 322; the mounting plate 321 is arranged on the rack 1, and the mounting plate 321 is in transmission connection with the buffer assembly 31; the threaded sleeve 322 is rotationally arranged on the mounting plate 321, the threaded sleeve 322 is in transmission connection with the rotating driving assembly 22, and the threaded sleeve 322 is in threaded connection with the main rod 21.

[0027] The application achieves the function of driving the buffer assembly 31 and the main rod 21 respectively by the first transmission assembly 32 through the mounting plate 321 and the threaded sleeve 322. The mounting plate 321 is fixedly connected with the mounting table 11. The threaded sleeve 322 is rotationally connected with the limiting ring 311, the top end of the main rod 21 is provided with the limiting ring 311 which is slidingly matched with the mounting table 11, and the limiting ring 311 is rotationally connected with the main rod 21, thereby avoiding the main rod 21 from being separated from the rack 1. Under the action of gravity and the elastic force of the first elastic member 314, the main rod 21 and the fork 211 have a downward trend, and at this time the main rod 21 is pulled by the elastic force of the first elastic member 314. When the first rotary driver 221 drives the main shaft 223 to rotate through the worm 224 and the worm wheel 225, the main shaft 223 drives the threaded sleeve 322 to rotate, and the threaded sleeve 322 is threadedly connected with the main rod 21. The threaded sleeve 322 has a trend of driving the main rod 21 to move upward when rotating, and when the rotation of the fork 211 is blocked, the main rod 21 cannot rotate, the threaded sleeve 322 drives the main rod 21 to move upward when rotating, the main rod 21 drives the fork 211 and the limiting ring 311 to move upward, and the first elastic member 314 is contracted. The elastic force of the first elastic member 314 increases, and when the elastic force of the first elastic member 314 and the resistance to the rotation of the fork 211 are balanced, the rotation of the threaded sleeve 322 will drive the main rod 21 to rotate synchronously, thereby driving the fork 211 to rotate at a constant speed. When the fork 211 is in contact with the obstacle and the rotation is blocked, the first rotary driver 221 still drives the main shaft 223 to rotate, the main shaft 223 drives the threaded sleeve 322 to rotate, at this time the fork 211 and the main rod 21 cannot rotate, the threaded sleeve 322 will drive the main rod 21 to move upward when rotating, the main rod 21 drives the fork 211 and the limiting ring 311 to move upward, further compresses the first elastic member 314, and the telescopic rod 313 is retracted into the mounting cylinder 312 until the fork 211 can push the obstacle to continue to rotate. After the obstacle is pushed away, the resistance to the fork 211 decreases. The limiting ring 311 is driven by the elastic force of the first elastic member 314, the threaded sleeve 322 has a downward trend, thereby the threaded sleeve 322 exerts pressure on the main rod 21, the rotation speed of the main rod 21 increases, a speed difference is generated between the threaded sleeve 322 and the main rod 21, the main rod 21 moves downward to reset, and the device operates at low power. If the fork 211 still cannot push away the obstacle after the torque increases, the limiting ring 311 is in contact with the mounting cylinder 312, the pressure sensor detects the pressure and feeds back a signal to the controller, the controller stops the first rotary driver 221, and the device stops operating.

[0028] Referring to Figures 2-5 , Figure 8 and Figure 9The first rotating gear 323 and the second rotating gear 324 are rotationally arranged on the mounting plate 321; the main rod 21 and the threaded sleeve 322 are both provided with two, which are connected with the two first rotating gears 323 respectively. The two first rotating gears 323 are sleeved on the two threaded sleeves 322 respectively, the two first rotating gears 323 are meshed and connected, the first rotating gear 323 is meshed and connected with the second rotating gear 324, and the second rotating gear 324 is drivingly connected with the rotating driving assembly 22.

[0029] The first rotating gear 323 and the second rotating gear 324 are rotationally arranged on the mounting plate 321; the main rod 21 and the threaded sleeve 322 are both provided with two, which are connected with the two first rotating gears 323 respectively. The two first rotating gears 323 are sleeved on the two threaded sleeves 322 respectively, the two first rotating gears 323 are meshed and connected, the first rotating gear 323 is meshed and connected with the second rotating gear 324, and the second rotating gear 324 is drivingly connected with the rotating driving assembly 22.

[0031] The mounting table 11 and the lifting assembly 12 are used to realize the function of controlling the lifting of the crushing mechanism 2. The limiting ring 311 is provided with a guide rod which is slidingly matched with the mounting table 11. The second elastic member 315 is arranged on the mounting table 11, and the two ends of the second elastic member 315 are connected with the limiting ring 311 and the mounting table 11 respectively, so that the connection strength of the main rod 21 and the mounting table 11 is further improved through the second elastic member 315. The operator first controls the mounting table 11 to move up through the lifting assembly 12, and the mounting table 11 drives the main rod 21 and the induction mechanism 3 to move up, so that the main rod 21 and the fork 211 are separated from the soil, and then the rack 1 is controlled to move through the cooperation of the motor and the wheel 14, so that the movement of the rack 1 is not affected by the main rod 21 and the fork 211. When the rack 1 moves to the pipe laying place, the mounting table 11 is controlled to move down through the lifting assembly 12, and in this process, the threaded sleeve 322 and the main rod 21 are driven to rotate through the first rotating driver 221, the main rod 21 drives the fork 211 to rotate, and the soil is crushed, so that the pipe laying mechanism 4 can perform the pipe laying work.

[0032] With reference to Figure 1 and Figure 7The rack 1 is provided with a material roll 41 for carrying a pipeline; the rack 1 is provided with a mounting frame 42 in transmission connection with the lifting assembly 12, and the pipeline on the material roll 41 is connected with the mounting frame 42.

[0033] The pipeline laying work is realized by the material roll 41 and the mounting frame 42. In the working state, when the lifting assembly 12 controls the mounting table 11 to move downward, the lifting assembly 12 controls the mounting frame 42 to move downward, and then the pipeline is driven downward by the mounting frame 42, and the pipeline is buried in the soil. The pipeline is a flexible pipeline. The guiding wheel 421 is rotatably arranged on the mounting frame 42, and the pipeline is supported and guided by the guiding wheel 421. With the movement of the rack 1, the pipeline is moved along the designated path and buried underground.

[0035] The second rotary driver 121, the screw rod 122 and the connecting frame 123 realize the function of driving the mounting table 11 to move up and down. The connecting frame 123 is connected with the mounting frame 42. The second rotary driver 121 is in transmission connection with the screw rod 122 through the transmission belt 124. In the working state, the operator sends a signal to the second rotary driver 121 through the controller, and the second rotary driver 121 drives the screw rod 122 to rotate after receiving the signal, and the screw rod 122 drives the connecting frame 123 in threaded connection with it to move downward, and the connecting frame 123 drives the mounting table 11 and the mounting frame 42 to move.

[0036] Referring to Figure 1 and Figure 10 : The rack 1 is provided with a soil covering roller 13 for compacting the soil.

[0037] The soil covering roller 13 realizes the function of compacting the soil. In the working state, after the pipeline is buried underground by the cooperation of the crushing mechanism 2 and the pipeline laying mechanism 4, the soil is compacted by the soil covering roller 13 behind the rack 1 with the movement of the rack 1, thereby improving the stability of the pipeline burial.

[0041] The above embodiment only expresses one or several embodiments of the application, and the description is more specific and detailed, but it cannot be understood as the limitation of the scope of the application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the application, several modifications and improvements can be made, which belong to the protection scope of the application. Therefore, the protection scope of the application should be subject to the appended claims.
