Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and particularly relates to a device for integrating drip irrigation tape laying and fertilization. Background Art

[0002] A drip irrigation tape is an agricultural device for precise irrigation. It directly delivers water to the roots of crops through a pipeline system to achieve the purpose of water conservation and efficient irrigation. Specifically, through small holes or drippers on the pipeline, water is slowly released in the form of drops or fine streams near the roots of crops. Since the water is directly delivered to the roots, the evaporation and leakage of water are reduced, and the water utilization efficiency is improved.

[0003] When laying traditional drip irrigation tapes, it is necessary to lay and bury the coiled drip irrigation tapes between two adjacent planting areas manually or by agricultural machinery. Since the laying efficiency of agricultural machinery is higher, mechanical laying is usually adopted in actual planting. However, during the process of laying drip irrigation tapes by the laying machinery, it is impossible to synchronously fertilize the planting areas on both sides of the drip irrigation tape, resulting in the need for manual fertilization work after the drip irrigation tape is laid, which reduces the efficiency of agricultural planting work. Summary of the Invention

[0004] In view of the above-mentioned drawbacks of the prior art, the present invention provides a device for integrating drip irrigation tape laying and fertilization, which can effectively solve the problem in the prior art that during the process of laying drip irrigation tapes by the laying machinery, it is impossible to synchronously fertilize the planting areas on both sides of the drip irrigation tape, resulting in the need for manual fertilization work after the drip irrigation tape is laid, which reduces the efficiency of agricultural planting work.

[0005] To achieve the above object, the present invention is realized through the following technical solutions:

[0013] The technical solution provided by the present invention has the following beneficial effects compared with the prior art:

[0014] The present invention is provided with a chassis for simultaneously installing and supporting the fertilizing component and the laying component, so that when the agricultural machinery equipment drives the chassis forward, the laying component can lay the drip irrigation tape, and at the same time, when the chassis moves forward, it drives the fertilizing component to operate and sprinkle the fertilizer into the planting belt areas on both sides of the drip irrigation tape through the fertilizing pipes, realizing the effect of simultaneous integration of drip irrigation tape laying and fertilization in the planting area, preventing the need for separate fertilization work after the drip irrigation tape is laid, bringing convenience to agricultural planting and improving agricultural planting efficiency.

[0015] The present invention is provided with laying pipes that can be translated to adjust the laying position.

[0036] The present invention will be further described below in conjunction with the embodiments.

[0037] See also Figures 1 - 13 The present invention provides a technical solution: a drip irrigation belt laying and fertilization integrated device, comprising:

[0038] The bottom frame 1 is used to connect agricultural machinery and equipment. The two sides of the top of the bottom frame 1 are fixedly provided with upright posts 11, and the tops of the upright posts 11 are fixedly provided with crossbeams 12;

[0041] A laying assembly 4 is arranged on a side of the chassis 1 away from the agricultural machinery;

[0042] The fertilization assembly 2 includes a plurality of fertilization pipes 21 arranged side by side. The fertilization pipes 21 are fixedly arranged at the bottom of the base frame 1 and are used to transport fertilizer to two adjacent planting belt areas.

[0043] The laying assembly 4 includes a plurality of laying pipes 41 arranged side by side, and the laying pipes 41 are all slidably arranged on the outside of the base frame 1, and the plurality of laying pipes 41 are staggered with the plurality of fertilization pipes 21, so as to guide the drip irrigation tape carried by the unwinding assembly 3 between two adjacent planting belt areas, and the plurality of laying pipes 41 can slide and translate laterally when driven by external force.

[0044] On both sides of the chassis 1, load-bearing wheels 13 are rotatably arranged and rotate under the traction of agricultural machinery equipment; the fertilizing assembly 2 further includes a fertilizer tank 22 fixedly arranged on the top of the cross beam 12. At the bottom of the fertilizer tank 22, grooved pulleys 23 are rotatably arranged. The grooved pulleys 23 are linked with the load-bearing wheels 13 through a chain 27. Specifically, a funnel 24 is fixedly arranged at the bottom of the fertilizer tank 22. A number of funnels 24 are arranged corresponding to the fertilizer application pipes 21. The funnels 24 are interconnected with the corresponding fertilizer application pipes 21 through connecting pipes 25. The fertilizer application pipes 21 are all fixedly arranged at the bottom of the chassis 1 through mounting blocks 26. A number of grooved pulleys 23 are arranged corresponding to the funnels 24 and are used to input the fertilizer inside the fertilizer tank 22 into the inside of the funnels 24. The several grooved pulleys 23 are coaxially connected, and a sprocket is arranged at the shaft end. This sprocket is cooperated with the chain 27 to be interlinked with the sprocket at the shaft end of the load-bearing wheel 13, so that the load-bearing wheel 13 drives the fertilizing assembly 2 to fertilize during the forward movement.

[0045] A number of V-shaped baffles 14 are arranged side by side at the bottom of the chassis 1 and are used to clean the lumps in front of the laying pipe 41. Among them, the number of V-shaped baffles 14 is one more than the number of laying pipes 41. After the laying pipe 41 is translated a certain distance, the V-shaped baffles 14 are used to continue cleaning the lumps in front. Specifically, the several V-shaped baffles 14 are all fixedly arranged at the bottom of the connecting plate 141. On the top of the connecting plate 141, vertical rods 142 are symmetrically and fixedly arranged. On the outside of each vertical rod 142, a limiting piece 143 is fixedly arranged. On the outside of the vertical rod 142, springs 144 are arranged at the top of the limiting piece 143. On the top of the chassis 1, a top plate 16 is fixedly arranged. The top plate 16 is slidably connected with the vertical rod 142 and is located at the top of the spring 144. And a rolling cage 15 is also rotatably arranged at the bottom of the chassis 1 and is used to compact the soil in front and crush the large soil blocks to reduce the influence of the large soil blocks on the subsequent laying of the drip irrigation belt.

[0046] A number of unwinding assemblies 3 are arranged corresponding to the laying assembly 4. The unwinding assembly 3 includes a bottom plate 31 slidably arranged on the top of the cross beam 12. On one side of the top of the bottom plate 31, a bearing plate 32 is fixedly arranged. On the other side of the top of the bottom plate 31, a support plate 33 is fixedly arranged. A reel 35 is arranged between the bearing plate 32 and the support plate 33 and is used to support the coiled drip irrigation belt.

[0047] A connecting piece 38 is rotatably arranged at one end of the reel 35. The connecting piece 38 is rotatably connected with the bearing plate 32 through a shaft head 34. The other end of the reel 35 is placed on the top of the support plate 33. Among them, a side plate 36 is fixedly arranged on the outside of one end of the reel 35 and is used to support the coiled drip irrigation belt when the reel 35 rotates to install the coiled drip irrigation belt.

[0048] A sliding hole 351 is axially formed in parallel on the outer side of the reel 35. The sliding holes 351 are evenly distributed around the axis of the reel 35. Wedge-shaped plates 37 are slidably arranged on the inner sides of the sliding holes 351. A conical block 371 for pushing the wedge-shaped plates 37 to slide is slidably arranged inside the reel 35. Among them, when the conical block 371 rotates upward, the extrusion of the wedge-shaped plates 37 is released by its own gravity.

[0049] A rotating member 352 is fixedly arranged at one end of the reel 35. The rotating member 352 is rotatably connected to the shaft head 34 through an adapter 38. A counterweight 39 is fixedly arranged at the bottom of the shaft head 34. An arc surface 391 is arranged on one side of the counterweight 39 away from the shaft head 34. One end of the conical block 371 is fixedly provided with a flower shaft 372. The flower shaft 372 is slidably arranged along the axis inside the rotating member 352. One end of the flower shaft 372 close to the arc surface 391 abuts against the end of the shaft head 34.

[0050] A first driving member 374 is fixedly arranged at one end of the conical block 371 close to the flower shaft 372. A second driving member 373 is fixedly arranged at one end of the flower shaft 372 close to the conical block 371. The first driving member 374 is threadedly connected inside the second driving member 373. A fixed shaft 375 extending outside the reel 35 is fixedly arranged at one end of the conical block 371 away from the first driving member 374. By rotating the fixed shaft 375 to drive the first driving member 374 to rotate and feed inside the second driving member 373, the locking position of the conical block 371 can be adjusted according to the inner diameter of the coiled drip irrigation tape take-up reel before use to adapt to drip irrigation tape reels with different inner diameters.

[0051] The laying component 4 further includes a sliding frame 42. A hydraulic push rod 43 is fixedly arranged on the outer side of the sliding frame 42. The driving end of the hydraulic push rod 43 is fixedly connected to the column 11 on one side, and is used to drive the sliding frame 42 to drive the laying pipe 41 to translate. The sliding frame 42 is slidably arranged on the outer sides of the chassis 1 and the cross beam 12. A bottom plate 31 is fixedly arranged on the top of the sliding frame 42. The laying pipe 41 is rotatably arranged on the outer side of the sliding frame 42 through a connecting member 421. Wherein, two rotating arms 413 are rotatably arranged at one end of the laying pipe 41 away from the chassis 1. Rotating discs 45 are rotatably arranged on the outer sides of the two rotating arms 413. The two rotating discs 45 are arranged in a V shape and are used for shallowly burying drip irrigation tapes. During the shallow burying process, the rotating discs 45 can cause the rotating arms 413 to rotate and adjust along with the change of the terrain. When the laying pipe 41 is lifted by agricultural machinery equipment, the rotating arms 413 are supported by the limiting blocks 414 on the outer side of the laying pipe 41, so that the rotating arms 413 always keep an inclined state with the ground, preventing the laying pipe 41 from falling and causing collision and extrusion to the rotating discs 45. At this time, when the drip irrigation tape starts to be laid, it is necessary for workers to press the end of the drip irrigation tape. As the agricultural machinery equipment advances, the coiled drip irrigation tape is pulled and unrolled. Specifically, a ditch opener 44 is fixedly arranged at one end of the laying pipe 41 close to the rotating disc 45. A fixing rod 412 is fixedly arranged on the outer side of the laying pipe 41. A tension spring 424 is movably connected to the outer side of the fixing rod 412. The other end of the tension spring 424 is movably connected to a slider 423. The rotating disc 45 connected to the end of the laying pipe 41 is tightly attached to the ground through the tension spring 424. And in order to facilitate adjusting the tension of the tension spring 424, a channel steel 422 is fixedly arranged on the outer side of the connecting member 421. The slider 423 is slidably arranged inside the channel steel 422. One end of the channel steel 422 close to the tension spring 424 is threadedly connected with a bolt 425. The end of the bolt 425 abuts against the outer side of the slider 423. By rotating the bolt 425, the distance between the slider 423 and the fixing rod 412 is adjusted, so as to realize the adjustment of the tension of the tension spring 424.

[0052] A pulling component 46 is arranged inside the laying pipe 41, and a driving wheel 47 is arranged outside the laying pipe 41. The laying pipe 41 rolls on the ground under traction to drive the operation of the pulling component 46; the pulling component 46 includes a driving roller 462 and a driven roller 465 that are interconnected and linked, and is used to pull and lay the drip irrigation tape supported by the unwinding component 3. The driving roller 462 is rotatably arranged inside the base 461 through a connecting shaft 4621, and the driven roller 465 is rotatably arranged inside the laying pipe 41. One of the driving rollers 462 is linked with the driving wheel 47; wherein, strip-shaped holes 411 are formed on both sides of the laying pipe 41, and the connecting shaft 4621 is slidably arranged inside the strip-shaped holes 411. When the chassis 1 is lifted by agricultural machinery equipment, the connecting shaft 4621 slides inside the strip-shaped holes 411 under the influence of gravity, so as to separate the driving roller 462 and the driven roller 465 from each other and pass through the drip irrigation tape; specifically, a gear A463 is fixedly arranged at one end of each driving roller 462, and a gear B464 is meshed between adjacent two gear A463s, so that a plurality of driving rollers 462 rotate in the same direction, and one of the gear B464s is coaxially fixed with the driving wheel 47; a gear C466 is fixedly arranged at one end of each driven roller 465, and a gear D467 is meshed between adjacent two gear C466s; in order to maintain the linkage between the driving roller 462 and the driven roller 465, and a gear box 468 is arranged at the shaft end of one of the driving rollers 462 and the shaft end of one of the gear D467s, and the two gear boxes 468 are interconnected through a telescopic shaft 469, so that when the base 461 drives the driving roller 462 to slide along the strip-shaped hole 411, it always maintains linkage with the driven roller 465.

[0053] Principle and advantages of the integrated device for drip irrigation tape laying and fertilization:

[0054] First of all, the chassis 1 is installed on the agricultural machinery equipment, and the hydraulic push rod 43 outside the sliding frame 42 is connected to the hydraulic control system of the agricultural machinery equipment. The agricultural machinery equipment and its hydraulic control system are both prior arts and will not be elaborated here; when laying the drip irrigation tape, the coiled drip irrigation tape is installed on the unwinding component 3 for support to ensure the smooth unwinding of the drip irrigation tape; the unwound drip irrigation tape passes through the laying pipe 41 and is located on the ground. As the agricultural machinery equipment moves forward, the end of the laying pipe 41 continuously outputs the drip irrigation tape, and the drip irrigation tape is located between the two rotating disks 45. At this time, since the two rotating disks 45 at the end of the laying pipe 41 are arranged in a V shape, the rotating disks 45 can turn the soil upward through their own rotation during the forward process to shallowly bury the drip irrigation tape, realizing the laying function of the drip irrigation tape. During the laying process, the tension spring 424 between the laying pipe 41 and the connecting piece 421 generates a pulling force on the laying pipe 41, so that the rotating disk 45 connected to the end of the laying pipe 41 closely adheres to the ground.

[0055] During the process of laying drip irrigation tapes, the load-bearing wheels 13 on both sides of the chassis 1 roll forward under the traction of agricultural machinery equipment. During the rolling process, the sprocket wheel 23 at the bottom of the fertilizer tank 22 is driven to rotate through the chain 27, so that the sprocket wheel 23 uses the outer groove to input the fertilizer inside the fertilizer tank 22 into the inside of the funnel 24. Each funnel 24 is separately shunted into the inside of the fertilizing pipe 21 through the connecting pipe 25 for fertilization; since the fertilizing pipe 21 and the laying pipe 41 are arranged staggeredly in the advancing direction, it is possible to fertilize the planting belt areas on both sides of the drip irrigation tape while the laying pipe 41 lays the drip irrigation tape; after each one-way fertilization, the agricultural machinery equipment needs to turn around and continue laying and releasing. At this time, the hydraulic control system of the agricultural machinery equipment can be used to drive the hydraulic push rod 43 to expand and contract, so that the hydraulic push rod 43 pushes the sliding frame 42 to slide outside the chassis 1 and the cross beam 12, thereby driving the laying pipes 41 arranged outside the chassis 1 to translate to one side, moving the laying pipes 41 to the position of the next laying, and at the same time continuously releasing the fertilizing pipes 21, so as to adjust the position of the laying pipes 41 according to the laying direction of the agricultural machinery equipment during the release process, making the operation of the agricultural machinery equipment more flexible during laying and fertilization.

[0056] Its advantages are as follows. By setting the chassis 1 to simultaneously install and support the fertilization component 2 and the laying component 4, when the agricultural machinery equipment drives the chassis 1 to move forward, the drip irrigation tape can be laid through the laying component 4. At the same time, when the chassis 1 moves forward, it drives the fertilization component 2 to operate and sprinkle the fertilizer into the planting belt areas on both sides of the drip irrigation tape through the fertilizing pipe 21, achieving the effect of integrated and synchronous progress of drip irrigation tape laying and planting area fertilization; preventing the need for separate fertilization work after the drip irrigation tape is laid, bringing convenience to agricultural planting and improving agricultural planting efficiency; and when the agricultural machinery equipment turns around and continues to lay, the laying position can be adjusted by translating the parallel laying pipes 41, achieving the effect of conveniently adjusting the laying position of the drip irrigation tape on the basis of continuous fertilization to adapt to different laying methods and making the agricultural machinery operation more convenient.

[0057] When installing the coiled drip irrigation tape on the unwinding assembly 3 in the integrated device for drip irrigation tape laying and fertilization of the present application, by rotating the reel 35 upward, the rotating member 352 at one end of the reel 35 rotates with the adapter 38, and then the other end of the reel 35 is lifted away from the top of the support plate 33. At this time, the reel 35 is in an inclined or vertical state, and the side plate 36 on its outer side is in an inclined or horizontal state. Moreover, the tapered block 371 inside the reel 35 automatically slides downward under the influence of gravity away from the inclined surface of the wedge plate 37, thereby releasing the squeezing on the wedge plate 37. Then, the coiled drip irrigation tape reel is sleeved on the outer side of the reel 35, and the drip irrigation tape reel is supported under the action of the side plate 36. Then, the lifted end of the reel 35 is lowered to the top of the support plate 33. Finally, the fixed shaft 375 is rotated to drive the tapered block 371 to rotate, so that the tapered block 371 drives the first driving member 374 to rotate and feed inside the second driving member 373, and the tapered block 371 gradually approaches the inclined surface of the wedge plate 37 until it is pressed tightly. At this time, the tapered block 371 pushes the flower shaft 372 and the shaft head 34 to squeeze each other through the first driving member 374 and the second driving member 373, so that the tapered block 371 pushes the wedge plate 37 to clamp the inner wall of the drip irrigation tape reel, so that the drip irrigation tape reel rotates through the bearing at one end of the reel 35 and the shaft head 34 at the other end during the unwinding process, so as to ensure the smoothness of the unwinding, and at the same time, it can avoid the unwinding deviation caused by the relative rotation of the drip irrigation tape reel with respect to the reel 35.

[0058] According to the adjustment effect during the first use, when replacing the coiled drip irrigation tape again, by lifting the reel 35 upward, one end of the flower shaft 372 rotates downward, and then the extrusion of the shaft head 34 on the flower shaft 372 is gradually released, so that the flower shaft 372 automatically slides downward under the action of gravity and abuts against the surface of the arc surface 391. When the reel 35 is in a vertical state, the end of the flower shaft 372 is still on the surface of the arc surface 391. After the coiled drip irrigation tape is replaced, by rotating the reel 35 downward to reset, the flower shaft 372 is pressed against the outside of the shaft head 34 again along the arc surface 391. At this time, the flower shaft 372 is squeezed by the shaft head 34 and pushes the tapered block 371 to squeeze the wedge plate 37, so that the wedge plate 37 automatically clamps and fixes the replaced drip irrigation tape reel.

[0059] It is worth noting that the above installation method has the following advantages:

[0060] Advantage 1: By rotating the reel 35 upward, the end of the reel 35 is disengaged from the support of the support plate 33, so as to facilitate sleeving the coiled drip irrigation tape on the outer side of the reel 35 for installation. And during installation, the coiled drip irrigation tape automatically slides down by gravity to the outside of the side plate 36 for support and limit, so as to facilitate the installation of drip irrigation tapes with different winding widths.

[0061] Advantage two: By rotating the fixed shaft 375 to adjust the extrusion position of the conical block 371 on the wedge plate 37, the wedge plate 37 can adapt to drip irrigation tape reels of different specifications, and by clamping and fixing the drip irrigation tape reel, it is prevented that there is a large gap between the drip irrigation tape reel and the reel 35 during the unwinding process, thereby increasing the unwinding resistance.

[0062] Advantage three: By setting the conical block 371 to extrude the wedge plate 37 to trigger the clamping action to ensure the stability of the drip irrigation tape reel. When the reel 35 is lifted upward, the conical block 371 automatically moves away from the inclined surface of the wedge plate 37 under the action of its own gravity, so that the wedge plate 37 automatically releases the clamping action in the state of replacing the drip irrigation tape. When the reel 35 rotates downward and resets again, the conical block 371 can be pushed by the flower shaft 372 to fix the drip irrigation tape reel again, achieving the effect of automatically relaxing and fixing the drip irrigation tape reel before and after replacing the drip irrigation tape.

[0063] Advantage four: By setting the shaft head 34 to press the end of the flower shaft 372 to ensure the fixing effect on the drip irrigation tape reel when the reel 35 is in a horizontal state. When the reel 35 rotates upward, the end of the flower shaft 372 gradually disengages from the outside of the shaft head 34 and abuts against the surface of the arc surface 391, preventing the arc surface 391 from separating from the counterweight 39 under the action of gravity. Under the action of the arc surface 391, when the reel 35 rotates downward and resets, it can guide the flower shaft 372 to abut against the shaft head 34 again.

[0064] Advantage five: By setting the counterweight 39 to limit the flower shaft 372 to ensure the smooth progress of repeated clamping. At the same time, after the drip irrigation tape outside the reel 35 is laid, under the action of the gravity of the counterweight 39, the shaft head 34 and the adapter 38 automatically rotate, thereby driving the reel 35 to rotate to a state where it can rotate upward, so that after the drip irrigation tape is laid, the reel 35 can be directly rotated for replacement work without separately rotating the reel 35 to a position where it can rotate upward, which is more convenient to use.

[0065] When the laying component 4 in the drip irrigation tape laying and fertilizing integrated device of the present application lays the drip irrigation tape:

[0066] First, before laying, after installing the coiled drip irrigation tape outside the reel 35, the agricultural machinery equipment drives the chassis 1 to lift upward, causing the chassis 1 to drive the laying component 4 away from the ground. At this time, the base 461 at the bottom of the laying pipe 41 drives the driving roller 462 to slide along the strip-shaped hole 411, thereby making the driving roller 462 move away from the driven roller 465, forming a channel for threading the drip irrigation tape between the driving roller 462 and the driven roller 465. This facilitates threading the free end of the drip irrigation tape into the interior of the laying pipe 41 and then reaching the end of the laying pipe 41 through the channel. At this time, the base 461 drives the outer gear box 468 to move away from the gear box 468 outside the laying pipe 41, and then the telescopic shaft 469 between the two gear boxes 468 expands and contracts to ensure that the driving roller 462 and the driven roller 465 are always linked;

[0067] During laying, the hydraulic drive system of the agricultural machinery equipment drives the chassis 1 to lower, causing the laying pipe 41 outside the chassis 1 to gradually tilt. During the tilting process, the driving wheel 47 located outside the base 461 first contacts the ground. Under the action of the driving wheel 47, the tilting process of the laying pipe 41 becomes smoother. And when the load-bearing wheels 13 on both sides of the chassis 1 have fallen in place, under the action of pressure, the driving wheel 47 pushes the base 461 to move upward along the strip-shaped hole 411, thereby causing the driving roller 462 inside the base 461 to cooperate with the driven roller 465 inside the laying pipe 41 to clamp the drip irrigation tape. As the agricultural machinery equipment moves forward, it drives the driving wheel 47 to start rolling forward, causing the driving wheel 47 to drive the driving roller 462 inside the base 461 to rotate in the same direction. At the same time, under the action of the two gear boxes 468, the driven roller 465 inside the laying pipe 41 rotates in the opposite direction relative to the driving roller 462. Thus, on the basis of clamping the drip irrigation tape, the effect of pulling and unwinding the drip irrigation tape is achieved. Therefore, during the process of laying the drip irrigation tape, it is not necessary to manually press and fix the end of the drip irrigation tape to achieve pulling and unwinding, making the laying of the drip irrigation tape more convenient.

[0068] It should be noted that the above laying method has the following advantages:

[0069] Advantage 1: By arranging the pulling component 46 inside the laying pipe 41, under the action of the pulling component 46, the drip irrigation tape can be automatically unwound and laid, without the need to manually press and fix the end of the drip irrigation tape at the beginning of laying, making the laying of the drip irrigation tape more convenient.

[0070] Advantage 2: By arranging the driving wheel 47 outside the base 461 to drive the operation of the driving roller 462 and the driven roller 465 to achieve the effect of pulling the drip irrigation tape, the laying of the drip irrigation tape is made more convenient. And the driving wheel 47 contacts the ground during the falling process of the laying pipe 41, which can be used to guide the laying pipe 41 to gradually tilt and reduce the resistance between the end connector of the laying pipe 41 and the ground.

[0071] Advantage three: The driving roller 462 and the driven roller 465 in the pulling assembly 46 achieve the pulling effect while clamping the drip irrigation tape. After the unwinding of the drip irrigation tape is completed, the chassis 1 and the laying assembly 4 can be lifted by agricultural machinery and equipment, so that the driving roller 462 automatically moves away from the driven roller 465 under the influence of gravity, thereby automatically forming a channel for threading the drip irrigation tape, facilitating the threading of a new drip irrigation tape through the laying pipe 41 and the pulling assembly 46 for re-arrangement when replacing the drip irrigation tape.

[0072] Advantage four: By providing strip-shaped holes 411 on both sides of the laying pipe 41 to guide the sliding of the base 461, a channel for threading the drip irrigation tape is formed inside the laying pipe 41 by relying on its own gravity. When the laying pipe 41 falls to the ground, under the action of the pressure of the laying pipe 41, the driving wheel 47 produces a supporting effect on the base 461, and then the base 461 drives the driving roller 462 to automatically press against the driven roller 465, facilitating the clamping and pulling of the drip irrigation tape after passing through the channel.
