Description

Technical Field

[0001] This utility model belongs to the field of drip irrigation tape technology, and specifically relates to a drip irrigation tape laying mechanism for planting Sorghum oleracea. Background Technology

[0002] Sorghum sorghum is an annual herbaceous plant belonging to the genus Sorghum of the Poaceae family. It possesses remarkable vitality, with a well-developed root system and thick adventitious roots at the base of its stems that can penetrate up to 2 meters underground. This allows it to thrive even in arid environments, making it crucial for the management of loess plateaus and grasslands. In areas where sorghum sorghum is planted, soil structure is significantly improved, as its root system helps to stabilize sand dunes, prevent wind erosion, and reduce soil and water loss. Furthermore, as a high-quality forage, sorghum sorghum is extremely nutritious, containing abundant crude protein and minerals, and is highly palatable, promoting rapid growth in livestock after consumption.

[0003] Drip irrigation tape laying devices are used to shallowly bury drip irrigation tape in the soil. For example, utility model patent with patent number CN202322562059.7 discloses a drip irrigation tape shallow burial laying device to complete the laying work of shallow burial irrigation.

[0004] Since Sorghum sulphureus is an annual herb, some soil from the previous year contains Sorghum sulphureus roots during the second year of planting. Especially when using drip irrigation tape laying devices, the roots of Sorghum sulphureus will entangle around the bottom of the drip irrigation tape laying device during the shallow burial process. When the roots of Sorghum sulphureus gradually accumulate at the bottom of the drip irrigation tape laying device, the soil covering roller at the bottom of the device will not function properly, making it impossible to complete the shallow burial of the drip irrigation tape. It may even block the drip irrigation tape laying device, requiring manual cleaning of the Sorghum sulphureus roots. Utility Model Content

[0005] Based on this, the present invention provides a drip irrigation tape laying mechanism for planting Sorghum sulphurica, to solve the technical problem in the prior art where the roots of Sorghum sulphurica tend to entangle around the bottom of the drip irrigation tape laying device. When the roots of Sorghum sulphurica gradually accumulate at the bottom of the drip irrigation tape laying device, the soil covering wheel at the bottom of the drip irrigation tape laying device cannot be used normally, making it impossible to complete the shallow burial laying of the drip irrigation tape, and may even block the drip irrigation tape laying device, requiring manual cleaning of the roots of Sorghum sulphurica.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0007] A drip irrigation tape laying mechanism for planting Sorghum oleracea, used for shallow burial laying of drip irrigation tape, includes a main beam, a support wheel, a guide rod, a soil covering roller, and a root-breaking knife. The support wheel is positioned above the main beam, and the drip irrigation tape is sleeved on the support wheel. The guide rod is connected to the main beam and located below the support wheel. The drip irrigation tape is pulled to the ground through the guide rod. The soil covering roller is connected to the guide rod and is used for rolling and covering soil. The root-breaking knife is connected to the guide rod and is located on the side away from the soil covering roller.

[0008] Preferably, the root-breaking knife includes a curved rod and a blade body, one end of the curved rod is connected to the guide rod, the blade body is connected to the other end of the curved rod, and cutting portions are provided on both sides of the blade body.

[0009] Preferably, the soil covering rollers are provided in pairs, the pair of soil covering rollers are arranged at an angle to each other, and in the vertical direction, the upper regions of the pair of soil covering rollers are close to each other, and the lower regions of the pair of soil covering rollers are far apart from each other.

[0010] Preferably, the soil covering roller includes an angle rod and a rotating roller, the rotating roller being rotatably sleeved on the angle rod, and the rotating roller being disc-shaped.

[0011] Preferably, the covering roller further includes a pair of limiting plates, the pair of limiting plates being disposed on both sides of the guide rod, the limiting plates being provided with positioning rods, the positioning rods being located on the side away from the guide rods, and the corner rods being fixedly sleeved on the positioning rods.

[0012] Preferably, a flow cavity is provided inside the guide rod, and the flow cavity extends through the guide rod along its length.

[0013] Preferably, a first roller is provided at one end of the guide rod, and the first roller is disposed opposite to the flow cavity.

[0014] Preferably, a second roller is provided at one end of the guide rod, the second roller is located on the side away from the first roller, and the second roller is disposed opposite to the flow cavity.

[0015] Preferably, the main beam includes a crossbeam and a locking component. The crossbeam is L-shaped, with one end connected to the erecting wheel and the other end connected to the locking component.

[0016] Preferably, the main beam further includes a first hinge rod, a second hinge rod, and a tension spring. One end of the first hinge rod is hinged to the crossbeam, and the other end of the first hinge rod is hinged to the guide rod. The second hinge rod is located below the first hinge rod, with one end hinged to the crossbeam and the other end hinged to the guide rod. The tension spring is located between the first and second hinge rods, with one end connected to the crossbeam and the other end connected to the guide rod. A limit rod is also provided on the first hinge rod, located between the crossbeam and the guide rod, and closer to the crossbeam.

[0017] Compared with the prior art, the present invention has at least the following advantages:

[0018] (1) The root-breaking knife penetrates into the soil 3cm-8cm deep and plows out a shallow furrow, so that the drip irrigation tape behind it can be laid into the furrow, which facilitates the shallow burial of the drip irrigation tape.

[0019] (2) The root-breaking knife will cut the roots of Sorghum sulphureus on the surface of the soil, preventing the roots of Sorghum sulphureus from getting tangled on the guide rod or the covering roller. At the same time, even if some of the roots of Sorghum sulphureus are not cut off, they will still get tangled on the root-breaking knife. The staff only needs to clean the roots of Sorghum sulphureus on the root-breaking knife regularly. This prevents the roots of Sorghum sulphureus from getting tangled on the guide rod or the covering roller. It can ensure that there are no tangled roots of Sorghum sulphureus around the covering roller and the guide rod, so as to achieve the shallow burial of the drip irrigation tape.

[0020] (3) The drip irrigation tape extending from the guide rod will be laid into the furrow opened by the root-breaking knife. As the covering roller moves, the soil turned over on both sides of the root-breaking knife will be backfilled and buried into the furrow. While completing the shallow burial of the drip irrigation tape, the land is leveled and the drip irrigation tape can be buried as a whole. Less of the drip irrigation tape is exposed, reducing the weathering rate of the drip irrigation tape. Attached Figure Description

Therefore, the terms describing positional relationships in the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0029] Please refer to Figures 1 to 5 A drip irrigation tape laying mechanism for planting Sorghum succinctrum, used for shallow burial laying of drip irrigation tape 600, includes a main beam 100, a mounting wheel 200, a guide rod 300, a soil covering roller 400, and a root-breaking knife 500.

[0030] The main beam 100 provides support and is connected to a drive device (such as a tractor). Movement of the drive device moves the main beam 100.

[0031] The support wheel 200 is disposed above the main beam 100, and the main beam 100 supports the support wheel 200. The support wheel 200 and the main beam 100 are detachably connected by bolts and nuts, or the support wheel 200 can be fixed to the main beam 100 by welding. The support wheel 200 can rotate freely, and the drip irrigation tape 600 is sleeved on the support wheel 200. The drip irrigation tape 600 is in the shape of a roll. When the drip irrigation tape 600 is sleeved on the support wheel 200 and the two are fixed to each other, pulling the drip irrigation tape 600 will drive the support wheel 200 to rotate.

[0032] The guide rod 300 is connected to the main beam 100 and is located below the support wheel 200. The drip irrigation tape 600 is pulled to the ground through the guide rod 300. The guide rod 300 has a guiding function, enabling the drip irrigation tape 600 to move along the guide rod 300 and preventing the drip irrigation tape 600 from deviating.

[0033] The soil covering roller 400 is connected to the guide rod 300. The soil covering roller 400 is used to roll and cover the soil. The drip irrigation tape 600 laid on the ground is shallowly buried by the soil covering roller 400 rolling and causing soil to accumulate.

[0034] The root-breaking blade 500 is connected to the guide rod 300, and the root-breaking blade 500 is located on the side away from the covering roller 400, that is, the root-breaking blade 500 is located in front of the covering roller 400. The root-breaking blade 500 can penetrate into the soil 3cm-8cm deep and cut the roots of Sorghum sulphureus on the soil surface. At the same time, the root-breaking blade 500 will plow a shallow furrow, and the drip irrigation tape 600 will be laid into the furrow.

[0035] Specific working method: Using a drive device (such as a tractor), the main beam 100 is connected to the tail of the drive device. The operator pulls the elongated, reel-like drip irrigation tape 600, causing both the tape and the mounting wheels 200 to rotate simultaneously. The tape extends downwards along the guide rod 300, burying one end in the soil. The drive device moves forward, moving the entire drip irrigation tape 600 laying mechanism. The root-breaking blade 500 penetrates 3-8 cm into the soil, creating shallow furrows. This allows the drip irrigation tape 600 to be laid into these furrows, facilitating shallow burial. Simultaneously, the root-breaking blade 500 cuts the surface roots of the sorghum sulphureus, preventing them from tangling with the guide rod 300 or the covering roller 400. Even if some uncut roots remain, they will still entangle with the root-breaking blade 500. In this case, only regular cleaning of the sorghum roots on the root-breaking knife 500 by staff is needed, preventing the sorghum roots from becoming entangled extensively on the guide rod 300 or the covering roller 400. In contrast, traditional drip irrigation tape 600 laying devices cannot create furrows; the drip irrigation tape 600 is laid on the soil surface and shallowly buried by the covering roller 400, leaving part of the drip irrigation tape 600 exposed. This makes the drip irrigation tape 600 prone to weathering and causes soil erosion. The existing trench has poor soil surface flatness. The drip irrigation tape 600 extending from the guide rod 300 will be laid into the furrow. As the covering roller 400 moves, the soil turned over on both sides of the root-breaking knife 500 will be backfilled and buried into the furrow. While completing the shallow burial of the drip irrigation tape 600, the land is flat and the drip irrigation tape 600 can be completely buried. Less of the drip irrigation tape 600 is exposed, reducing the weathering rate of the drip irrigation tape 600.

[0036] In one possible embodiment, see Figure 2 The root-breaking knife 500 includes a curved rod 510 and a blade body 520. One end of the curved rod 510 is connected to the guide rod 300. Specifically, the connection between the curved rod 510 and the guide rod 300 is located on the side closer to the ground. The blade body 520 is connected to the other end of the curved rod 510. Cutting sections 521 are provided on both sides of the blade body 520. The cutting sections 521 are relatively sharp and can cut or break the roots of the sorghum sulphureus. The blade body 520 will plow a furrow of 3cm-8cm in the soil, allowing the drip irrigation tape 600 to be laid in the furrow. For a small portion of the sorghum sulphureus roots that are not cut, they will wrap around the curved rod 510 along the blade body 520, preventing the uncut sorghum sulphureus roots from wrapping around the covering roller 400 or the guide rod 300.

[0037] In one possible embodiment, see Figure 1The support pole includes a U-shaped frame 210, a connecting shaft 220, and a pair of limiting discs 230. The U-shaped frame 210 is fixed on the main beam 100. The connecting shaft 220 is rotatably mounted on the U-shaped frame 210, such as through a bearing. The pair of limiting discs 230 pass through the connecting shaft 220 and are located between the U-shaped frames 210. The rolled drip irrigation tape 600 is sleeved on and fixed on the connecting shaft 220 and is located between the pair of limiting discs 230. The rolled drip irrigation tape 600 rotates coaxially with the connecting shaft 220. The pair of limiting discs 230 are used to limit the drip irrigation tape 600 and prevent it from shifting.

[0038] In one possible embodiment, see Figure 1 The soil covering rollers 400 are provided in pairs, and the pair of soil covering rollers 400 are arranged at an angle to each other. In the vertical direction, the upper regions of the pair of soil covering rollers 400 are close to each other, and the lower regions of the pair of soil covering rollers 400 are far apart. When the soil covering rollers 400 rotate, as the soil covering rollers 400 move forward, the soil turned over by the root-breaking knife 500 is carried by the lower regions of the pair of soil covering rollers and backfilled into the furrow, thus serving the function of shallowly burying the drip irrigation tape 600.

[0039] In a preferred embodiment, see Figure 5 The soil-covering roller 400 includes an angle rod 410 and a rotating roller 420. The rotating roller 420 is rotatably sleeved on the angle rod 410 and can rotate around the angle rod 410. The two angle rods 410 extend in opposite directions. The rotating roller 420 is installed at the end of the angle rod 410. The upper regions of the pair of rotating rollers 420 are close to each other, and the lower regions of the pair of rotating rollers 420 are far apart. The rotating roller 420 is disc-shaped, and the inner cavity of the disc-shaped rotating roller 420 is relatively large, which can hold more soil for shallow burial of drip irrigation tape 600.

[0040] In one possible embodiment, see Figure 5The covering roller 400 further includes a pair of limiting plates 430, which are disposed on both sides of the guide rod 300. A preset distance is maintained between the pair of limiting plates 430. A positioning rod 431 is provided on each limiting plate 430, located on the side away from the guide rod 300. An angle rod 410 is fixedly sleeved on the positioning rod 431. The positioning rod 431 is used to adjust the distance between the pair of limiting plates 430 from the guide rod 300. The extended drip irrigation tape 600 enters between the pair of limiting plates 430, and then is rotated by the rear rotating roller 420, which shallowly buries the drip irrigation tape 600 between the pair of limiting plates 430 in the furrow. On the one hand, the limiting plates 430 can limit the drip irrigation tape 600 to ensure that the drip irrigation tape 600 falls into the furrow; on the other hand, the limiting plates 430 have a protective function to prevent the roots of sorghum from entering the rotating roller 420 and getting tangled on the rotating roller 420.

[0041] In a preferred embodiment, see Figure 5 The guide rod 300 has a flow cavity 310 that extends through it along its length. The drip irrigation tape 600, pulled from the mounting wheel 200, enters the flow cavity 310 and extends from the end near the soil covering roller 400 into the furrow in the soil. The flow cavity 310 serves to limit movement, preventing the drip irrigation tape 600 from shifting during its entry into the furrow.

[0042] In a preferred embodiment, see Figure 1 or Figure 5 The guide rod 300 has a first roller 320 at one end, which is positioned opposite to the flow cavity 310. To prevent the drip irrigation tape 600 from getting stuck on the edge of the guide rod 300, it is placed on the first roller 320. When the drip irrigation tape 600 stretches, it drives the first roller 320 to rotate, preventing the tape from getting stuck on the edge of the guide rod 300 and ensuring that the tape can quickly enter the flow cavity 310.

[0043] In a preferred embodiment, see Figure 5 A second roller 330 is provided at one end of the guide rod 300. The second roller 330 is located on the side away from the first roller 320 and is disposed opposite to the flow cavity 310. The second roller 330 has the same function as the first roller 320, preventing the drip irrigation tape 600 from getting stuck on the edge of the guide rod 300, so as to ensure that the drip irrigation tape 600 can quickly slide out of the flow cavity 310.

[0044] In one possible embodiment, see Figure 1 The main beam 100 includes a crossbeam 110 and a locking member 120. The crossbeam 110 is L-shaped, with one end connected to the support wheel 200 and the other end connected to the locking member 120. The crossbeam 110 mainly supports and connects the support wheel 200 and the guide rod 300. The locking member 120 is detachably connected to the tail of the drive device. The locking member 120 is equipped with a locking pin. When relative movement between the locking member 120 and the tail of the drive device is required, the locking pin is opened; when relative movement is not required, the locking pin is closed, thus fixing the locking member 120 relative to the tail of the drive device.

[0045] In one possible embodiment, see Figure 1 or Figure 5 For uneven ground, the depth of the furrows created by the root-breaking knife 500 will change. If the furrow depth becomes shallow, the soil-covering roller 400 will be unable to shallowly bury the drip irrigation tape 600. The main beam 100 also includes a first hinge rod 130, a second hinge rod, and a tension spring 150. One end of the first hinge rod 130 is hinged to the crossbeam 110, and the other end is hinged to the guide rod 300. The second hinge rod 140 is located below the first hinge rod 130. One end of the second hinge rod 140 is hinged to the crossbeam 110, and the other end is hinged to the guide rod 300. The tension spring 150 is located between the first hinge rod 130 and the second hinge rod 140. One end of the tension spring 150 is connected to the crossbeam 110, and the other end is connected to the guide rod 300. The end is connected to the guide rod 300; when there is a convex surface, the root-breaking knife 500 shifts vertically upward, causing the first hinge rod 130 and the second hinge rod 140 to rotate upward, and the tension spring 150 extends, so that the furrow opened by the root-breaking knife 500 is at a furrow depth of 3cm-8cm, avoiding the furrow depth being too deep; similarly, when there is a concave surface, the root-breaking knife 500 shifts vertically downward, causing the first hinge rod 130 and the second hinge rod 140 to rotate downward, and the tension spring 150 shortens, so that the furrow opened by the root-breaking knife 500 is at a furrow depth of 3cm-8cm, avoiding the furrow depth being too shallow.

[0046] In a preferred embodiment, see Figure 1 or Figure 5The first hinge rod 130 is also provided with a limiting rod 131, which is located between the crossbeam 110 and the guide rod 300, and is located on the side closer to the crossbeam 110. When there is a deep depression in the ground, in order to prevent the first hinge rod 130 and the second hinge rod 140 from moving down too far and deforming the tension spring 150, the limiting rod 131 is provided. When the first hinge rod 130 and the second hinge rod 140 move down too far, the limiting rod 131 will abut against the crossbeam 110, preventing the first hinge rod 130 and the second hinge rod 140 from moving down to the maximum distance that the tension spring 150 shortens, thus limiting the continuous contraction of the tension spring 150.

[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
