Description

Technical Field

[0001] The present invention belongs to the technical field of drip irrigation tapes, and particularly relates to a device for laying drip irrigation tapes for sorghum sudanense planting. Background Art

[0002] Sorghum sudanense is an annual herbaceous plant of the genus Sorghum in the family Poaceae. Sorghum sudanense has extremely strong vitality. Its root system is developed, and there are relatively thick adventitious roots at the base of the stem, which can penetrate up to 2 meters underground and still thrive in arid environments. This characteristic enables it to play an important role in the treatment of loess land or grasslands. In areas where sorghum sudanense is planted, the soil structure is significantly improved. Its root system can fix sand and prevent wind erosion, reducing soil erosion. At the same time, sorghum sudanense, as high-quality forage, has extremely high nutritional value. It is rich in crude protein and minerals, has good palatability, and livestock grow rapidly after consumption.

[0003] The drip irrigation tape laying device is used for shallowly burying drip irrigation tapes in the soil. For example, the utility model patent with the patent number CN202322562059.7 discloses a device for shallowly burying drip irrigation tapes to complete the laying work of shallow irrigation. During the planting process of sorghum sudanense, in order to ensure the normal growth of sorghum sudanense, for lands with different soil fertilities, such as lands with high soil fertility, sorghum sudanense is planted more densely and the crop row spacing is narrower; while for lands with low soil fertility, sorghum sudanense is planted more sparsely and the crop row spacing is wider. Or, sorghum sudanense needs to be intercropped with other crops, and the row spacing during the planting process of sorghum sudanense also needs to be adjusted. Correspondingly, when the row spacing of sorghum sudanense planting changes, the laying spacing of the drip irrigation tape also needs to be adjusted so that the laying spacing of the drip irrigation tape matches the row spacing of sorghum sudanense, making the drip irrigation tape as close as possible to the growth area of sorghum sudanense, thereby ensuring water supply for the growth of sorghum sudanense.

[0004] If the existing drip irrigation tape laying device adopts a single-row laying method, the laying efficiency is low and the laying time is long. If the drip irrigation tape laying device adopts a multi-row laying method, however, the existing drip irrigation tape laying device is integrally fixedly installed, and it is rather troublesome to adjust the laying spacing of the drip irrigation tape, and the laying spacing of the drip irrigation tape cannot be quickly adjusted.

Therefore, the terms describing the positional relationship in the drawings are only for illustrative purposes and cannot be understood as a limitation of this patent. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0029] Please refer to Figure 1 , a drip irrigation tape laying device for sorghum sudanense planting, used for shallowly laying multiple rows of drip irrigation tapes 400, including several groups of drip irrigation tape laying mechanisms 100, a spacing adjusting mechanism 200 is arranged between adjacent drip irrigation tape laying mechanisms 100, and an auxiliary traction frame body 300, the auxiliary traction frame body 300 is movably connected with several groups of drip irrigation tape laying mechanisms 100, and the auxiliary traction frame body 300 is used to traction several groups of drip irrigation tape laying mechanisms 100 to move synchronously.

[0030] The spacing adjustment mechanism 200 includes a spacing sleeve 210, a lead screw 220, an adjustment handle 230, and a rotating collar 240. One end of the spacing sleeve 210 is connected to the drip irrigation tape laying mechanism 100, and the spacing sleeve 210 and the drip irrigation tape laying mechanism 100 can be connected by means of screw connection or welding. The lead screw 220 is rotatably sleeved in the spacing sleeve 210. An external thread is provided on the surface of the lead screw 220, and an internal thread is provided in the spacing sleeve 210. The external thread can be screwed with the internal thread so that the lead screw 220 can rotate in the spacing sleeve 210. The adjustment handle 230 is fixedly sleeved on the lead screw 220, and the adjustment handle 230 and the lead screw 220 can be fixed by means of welding. One end of the rotating collar 240 is rotatably sleeved with the lead screw 220. When the lead screw 220 is rotated by the rotating handle, the lead screw 220 can be driven to rotate around the rotating collar 240. The other end of the rotating collar 240 is connected to the adjacent drip irrigation tape laying mechanism 100.

[0031] The specific process of spacing adjustment is as follows: A plurality of groups of the drip irrigation tape laying mechanisms 100 are connected to the auxiliary traction frame 300, and the auxiliary traction frame 300 is connected to a driving device (such as a tractor). According to the planting method of sorghum sudanense, for example, according to the soil fertility level, the row spacing for planting sorghum sudanense needs to be changed. The laying spacing of the drip irrigation tape 400 is adjusted according to the planting spacing of sorghum sudanense. When the spacing between adjacent drip irrigation tape laying mechanisms 100 needs to be adjusted, for example, when the laying spacing of the drip irrigation tape 400 needs to be widened, the adjustment handle 230 is rotated, and the lead screw 220 is screwed to rotate in the reverse direction, so that the lead screw 220 extends out of the spacing sleeve 210, and the adjacent drip irrigation tape laying mechanism 100 is pushed to become wider. When the laying spacing of the drip irrigation tape 400 is adjusted to an appropriate value, the adjustment handle 230 stops rotating, and adjacent drip irrigation tape laying mechanisms 100 are adjusted in sequence until the adjustment is completed; similarly, when the laying spacing of the drip irrigation tape 400 needs to be narrowed, the lead screw 220 is screwed to rotate in the forward direction by the adjustment handle 230. By screwing the lead screw 220 to rotate in the forward or reverse direction by the adjustment handle 230, the adjustment method is simple and convenient, and the spacing between adjacent drip irrigation tape laying mechanisms 100 can be quickly adjusted, so as to achieve the adjustment of the laying spacing of the drip irrigation tape 400. At the same time, through the adjustment method of the lead screw 220, the structural strength is high, it is not easy to be damaged, not easy to be blocked, and has a long service life.

[0032] In a preferred embodiment, refer to Figure 4, in order to prevent the screw rod 220 from rotating within the spacing sleeve 210 during the movement of the drip irrigation tape laying mechanism 100, the spacing adjustment mechanism 200 further includes a locking pin 250. The locking pin 250 is adjustably arranged on the spacing sleeve 210, and the locking pin 250 and the spacing sleeve 210 can be connected by means of screw thread engagement. One end of the locking pin 250 passes through the spacing sleeve 210 and abuts against the surface of the screw rod 220. After the laying spacing between adjacent drip irrigation tape laying mechanisms 100 is adjusted, rotate the locking pin 250 to make the locking pin 250 move towards the inside of the spacing sleeve 210 and abut against the bottom of the thread groove of the screw rod 220 inside the spacing sleeve 210, locking the screw rod 220 inside the spacing sleeve 210 to prevent the screw rod 220 from rotating within the spacing sleeve 210.

[0033] In a possible embodiment, refer to Figure 4 , when adjusting the spacing between the drip irrigation tape laying mechanisms 100, since the drip irrigation tape laying mechanisms 100 are in contact with the ground, it is rather laborious to rotate the rotating handle to push the drip irrigation tape laying mechanisms 100 through the reverse rotation of the screw rod 220. The auxiliary traction frame 300 includes a traction rod 310, an auxiliary frame 320 and an adjustable air cylinder 330. The traction rod 310 is connected to several groups of the drip irrigation tape laying mechanisms 100. The auxiliary frame 320 is detachably connected to the traction rod 310. One end of the adjustable air cylinder 330 is rotatably connected to the auxiliary frame 320, and the other end of the adjustable air cylinder 330 is rotatably connected to the drip irrigation tape laying mechanism 100. When it is necessary to adjust the spacing between the drip irrigation tape laying mechanisms 100, contract the adjustable air cylinder 330. The adjustable air cylinder 330 will pull the drip irrigation tape laying mechanism 100 to rotate around the auxiliary traction frame 300, pull the drip irrigation tape laying mechanism 100 upward to make the drip irrigation tape laying mechanism 100 away from the ground, and then rotate the screw rod 220 by rotating the rotating handle to further push the drip irrigation tape laying mechanism 100 to move, so as to adjust the spacing between adjacent drip irrigation tape laying mechanisms 100. Since the drip irrigation tape laying mechanism 100 is not in contact with the ground, it is more labor-saving to manually rotate the rotating handle.

[0034] In a possible embodiment, refer to Figure 5 , the drip irrigation tape laying mechanism 100 includes a main body beam 110, a laying wheel 120, a guiding rod 130, a soil covering roller 140 and a root breaking knife 150.

[0035] The main beam 110 has a supporting function. At the same time, the main beam 110 is connected to the auxiliary traction frame 300. When the auxiliary traction frame 300 moves, it drives the main beam 110 to move. Specifically, the main beam 110 can be movably sleeved on the traction rod 310, and the main beam 110 can rotate around the axis of the traction rod 310.

[0036] The erection wheel 120 is arranged above the main beam 110. The main beam 110 is used to support the erection wheel 120. The erection wheel 120 and the main beam 110 can be detachably connected by bolts and nuts, or the erection wheel 120 can be fixed on the main beam 110 by welding; the erection wheel 120 can rotate freely. The drip irrigation tape 400 is sleeved on the erection wheel 120. The drip irrigation tape 400 is in a reel shape. When the drip irrigation tape 400 is sleeved on the erection wheel 120 and the two are fixed to each other, when the drip irrigation tape 400 is pulled, it will drive the erection wheel 120 to rotate.

[0037] The guide rod 130 is connected to the main beam 110 and is located below the erection wheel 120. The drip irrigation tape 400 is guided to the ground through the guide rod 130. The guide rod 130 has a guiding function, enabling the drip irrigation tape 400 to move along the guide rod 130 and preventing the drip irrigation tape 400 from shifting.

[0038] The soil covering roller 140 is connected to the guide rod 130. The soil covering roller 140 is used for rolling and covering the soil. The drip irrigation tape 400 laid on the ground is driven by the rolling of the soil covering roller 140 to drive the soil to accumulate, and the drip irrigation tape 400 is shallowly buried and laid.

[0039] The root-breaking knife 150 is connected to the guide rod 130, and the root-breaking knife 150 is located on the side away from the soil covering roller 140, that is, the root-breaking knife 150 is located in front of the soil covering roller 140. The root-breaking knife 150 can penetrate into the soil by 3 cm - 8 cm, cut off the roots of sorghum sudanense on the soil surface. At the same time, the root-breaking knife 150 will plow out a relatively shallow furrow, and the drip irrigation tape 400 will be laid into the furrow.

[0040] The specific working mode of the drip irrigation tape laying mechanism 100 is as follows: The staff pulls the reel-shaped drip irrigation tape 400 to extend. The drip irrigation tape 400 and the erection wheel 120 rotate simultaneously. The drip irrigation tape 400 extends downward along the guide rod 130, and one end of the drip irrigation tape 400 is buried in the soil. The driving device moves forward, driving the whole drip irrigation tape 400 laying device to move. The root-breaking knife 150 penetrates 3 cm - 8 cm into the soil. The root-breaking knife 150 will plow out a relatively shallow furrow, so that the subsequent drip irrigation tape 400 will be laid into the furrow, facilitating the shallow burial laying of the drip irrigation tape 400. At the same time, the root-breaking knife 150 will cut off the roots of Sorghum sudanense on the soil surface, preventing the roots of Sorghum sudanense from winding around the guide rod 130 or the soil covering roller 140. At the same time, even if some uncut roots of Sorghum sudanense remain, they will wind around the root-breaking knife 150. The staff only needs to regularly clean the roots of Sorghum sudanense on the root-breaking knife 150 to prevent the roots of Sorghum sudanense from winding around the guide rod 130 or the soil covering roller 140 to a large extent. For the traditional drip irrigation tape 400 laying device, it cannot open a furrow. The drip irrigation tape 400 is laid on the soil surface, and the drip irrigation tape 400 is shallowly buried by the soil covering roller 140, resulting in part of the drip irrigation tape 400 still being exposed, making the drip irrigation tape 400 prone to weathering, and the land will have grooves and the flatness of the land surface is poor. The drip irrigation tape 400 extending from the guide rod 130 will be laid into the furrow. As the soil covering roller 140 moves, the soil turned out on both sides of the root-breaking knife 150 will be backfilled and buried into the furrow. While completing the shallow burial of the drip irrigation tape 400, it ensures the flatness of the land and can bury the drip irrigation tape 400 as a whole. The drip irrigation tape 400 is less exposed, reducing the weathering rate of the drip irrigation tape 400.

[0041] In a possible embodiment, refer to Figure 6 , the root-breaking knife 150 includes a curved rod 151 and a knife body 152. One end of the curved rod 151 is connected to the guide rod 130. Specifically, the connection position of the curved rod 151 and the guide rod 130 is on the side close to the ground. The knife body 152 is connected to the other end of the curved rod 151. Cutting parts 1521 are arranged on both sides of the knife body 152. The cutting parts 1521 are relatively sharp and can cut off the roots of Sorghum sudanense or break the roots of Sorghum sudanense. The knife body 152 will plow out a 3 cm - 8 cm furrow in the land, so that the drip irrigation tape 400 is laid into the furrow. For a small part of the uncut roots of Sorghum sudanense, they will wind around the curved rod 151 along the knife body 152, preventing the uncut roots of Sorghum sudanense from winding around the soil covering roller 140 or the guide rod 130.

[0042] In a possible embodiment, refer to Figure 1, the erection rod includes a U-shaped frame 121, a connecting shaft 122 and a pair of limiting discs 123. The U-shaped frame 121 is fixed on the main body beam 110. The connecting shaft 122 is rotatably arranged in the U-shaped frame 121, for example, rotatable connection is achieved through a bearing. A pair of the limiting discs 123 are arranged through the connecting shaft 122 and are located between the U-shaped frames 121. The reel-shaped drip irrigation tape 400 is sleeved and fixed on the connecting shaft 122 and is located between a pair of the limiting discs 123. The reel-shaped drip irrigation tape 400 rotates coaxially with the connecting shaft 122. A pair of the limiting discs 123 are used to limit the drip irrigation tape 400 to prevent the drip irrigation tape 400 from shifting.

[0043] In a possible embodiment, there are a pair of the soil covering rollers 140. The pair of the soil covering rollers 140 are arranged obliquely relative to each other. And in the vertical direction, the upper regions of the pair of the soil covering rollers 140 are close to each other, and the lower regions of the pair of the soil covering rollers 140 are far from each other. As the soil covering rollers 140 rotate and move forward, the soil turned out on both sides of the root breaking knife 150 will be wrapped by the lower regions of the pair of the soil covering rollers 140 and backfilled into the plow furrow, playing a role in shallowly burying the drip irrigation tape 400.

[0044] In a preferred embodiment, refer to Figure 9 , the soil covering roller 140 includes an angle rod 141 and a rotating roller 142. The rotating roller 142 is rotatably sleeved on the angle rod 141. The rotating roller 142 can rotate around the angle rod 141. The extending directions of the two angle rods 141 are opposite. The rotating roller 142 is installed at the end of the angle rod 141. The upper regions of the pair of the rotating rollers 142 are close to each other, and the lower regions of the pair of the rotating rollers 142 are far from each other. The rotating roller 142 is in a disc shape. The inner cavity of the disc-shaped rotating roller 142 is relatively large and can wrap more soil, which is used for shallowly burying the drip irrigation tape 400.

[0045] In a possible embodiment, refer to Figure 1, the soil covering roller 140 further includes a pair of limiting plates 143. The pair of limiting plates 143 are arranged on both sides of the guiding rod 130. There is a preset distance between the pair of limiting plates 143. A positioning rod 1431 is arranged on the limiting plate 143. The positioning rod 1431 is located on the side away from the guiding rod 130. The corner rod 141 is fixedly sleeved on the positioning rod 1431. The positioning rod 1431 is used to adjust the distance between the pair of limiting plates 143. The drip irrigation tape 400 extending from the guiding rod 130 will enter between the pair of limiting plates 143, and then pass through the rotation of the rear rotating roller 142 to shallowly bury the drip irrigation tape 400 between the pair of limiting plates 143 in the plow furrow. On the one hand, the limiting plate 143 can limit the drip irrigation tape 400 to ensure that the drip irrigation tape 400 falls into the plow furrow; on the other hand, the limiting plate 143 has a protective effect to prevent the roots of sorghum sudanense from entering the rotating roller 142 and winding around the rotating roller 142.

[0046] In a preferred embodiment, see Figure 9 , a flow cavity 131 is formed in the guiding rod 130. Along the length direction of the guiding rod 130, the flow cavity 131 runs through the guiding rod 130. The drip irrigation tape 400 pulled from the erection wheel 120 will enter the flow cavity 131 and extend out from one end close to the soil covering roller 140 and enter the plow furrow in the land. The flow cavity 131 has a limiting effect to prevent the drip irrigation tape 400 from shifting during the process of entering the plow furrow.

[0047] In a preferred embodiment, see Figure 9 , a first roller 132 is arranged at one end of the guiding rod 130. The first roller 132 is arranged opposite to the flow cavity 131. For the drip irrigation tape 400 entering the flow cavity 131, in order to prevent the drip irrigation tape 400 from getting stuck on the edge of the guiding rod 130, the drip irrigation tape 400 is placed on the first roller 132. When the drip irrigation tape 400 is stretched and extended, it will drive the first roller 132 to rotate, preventing the drip irrigation tape 400 from getting stuck on the edge of the guiding rod 130 to ensure that the drip irrigation tape 400 can quickly enter the flow cavity 131.

[0048] In a preferred embodiment, see Figure 9 , a second roller 133 is arranged at one end of the guiding rod 130. The second roller 133 is located on the side away from the first roller 132. The second roller 133 is arranged opposite to the flow cavity 131. The function of the second roller 133 is the same as that of the first roller 132, preventing the drip irrigation tape 400 from getting stuck on the edge of the guiding rod 130 to ensure that the drip irrigation tape 400 can quickly slide out of the flow cavity 131.

[0049] In a possible embodiment, referring to Figure 9 , the main beam 110 includes a cross beam 111 and a locking member 112. The cross beam 111 is in an "L" shape. One end of the cross beam 111 is connected to the erection wheel 120, and the other end of the cross beam 111 is connected to the locking member 112. The cross beam 111 is mainly used to support and connect the erection wheel 120 and the guide rod 130. The locking member 112 is rotatably connected to the traction rod 310. When the adjustable cylinder 330 extends or contracts, it will drive the locking member 112 to rotate around the axis of the traction rod 310. Specifically, the locking ring is in a circular shape and is sleeved coaxially with the traction rod 310. At the same time, a locking pin is provided on the locking member 112. When it is necessary for the locking member 112 to rotate around the axis of the traction rod 310, the locking pin is opened so that the locking member 112 can rotate around the axis of the traction rod 310. When it is not necessary for the locking member 112 to rotate around the axis of the traction rod 310, the locking pin is closed so that the locking member 112 is relatively fixed to the traction rod 310.

[0050] In a possible embodiment, referring to Figure 9 , for the condition of uneven ground, the depth of the plow groove opened by the root-breaking knife 150 will change. For example, if the depth of the plow groove becomes shallower, it will cause the soil covering roller 140 to be unable to shallowly bury the drip irrigation belt 400. The main beam 110 further includes a first hinge rod 113, a second hinge rod and a tension spring 115. One end of the first hinge rod 113 is hinged to the cross beam 111, and the other end of the first hinge rod 113 is hinged to the guide rod 130. The second hinge rod 114 is located below the first hinge rod 113. One end of the second hinge rod 114 is hinged to the cross beam 111, and the other end of the second hinge rod 114 is hinged to the guide rod 130. The tension spring 115 is located between the first hinge rod 113 and the second hinge rod 114. One end of the tension spring 115 is connected to the cross beam 111, and the other end of the tension spring 115 is connected to the guide rod 130. When there is a convex ground, the root-breaking knife 150 deflects vertically upward, driving the first hinge rod 113 and the second hinge rod 114 to rotate upward, and the tension spring 115 extends, so that the depth of the plow groove opened by the root-breaking knife 150 is between 3 cm and 8 cm, avoiding the plow groove depth being too deep. Similarly, when there is a concave ground, the root-breaking knife 150 deflects vertically downward, driving the first hinge rod 113 and the second hinge rod 114 to rotate downward, and the tension spring 115 shortens, so that the depth of the plow groove opened by the root-breaking knife 150 is between 3 cm and 8 cm, avoiding the plow groove depth being too shallow.

[0051] In a preferred embodiment, a limiting rod 1131 is further provided on the first hinge rod 113. The limiting rod 1131 is located between the cross beam 111 and the guide rod 130 and on the side close to the cross beam 111. When a relatively deep concave ground appears, in order to prevent the first hinge rod 113 and the second hinge rod 114 from moving down too far and squeezing the tension spring 115 to deform, the limiting rod 1131 is provided. When the first hinge rod 113 and the second hinge rod 114 move down too far, the limiting rod 1131 will abut against the cross beam 111 to prevent the first hinge rod 113 and the second hinge rod 114 from moving down, that is, the maximum distance by which the tension spring 115 shortens, and limit the continuous contraction of the tension spring 115.
