Description

Technical Field

[0001] This disclosure relates to the field of cotton planting technology, specifically to a drip irrigation tape positioning and fixing device and drip irrigation equipment suitable for ultra-wide film cotton fields. Background Technology

[0002] Ultra-wide film cotton fields typically refer to cotton fields with a large number of planting rows and a wide film coverage. Ultra-wide film cotton fields have a high planting density. From the perspective of cotton's physiological characteristics, the effective absorption roots of cotton are mainly concentrated in the soil layer 5-10 cm away from the plant stem. This area is the key area for water and nutrient absorption. Therefore, drip irrigation tape must be precisely laid in the furrow between two rows of cotton plants to ensure that water droplets can directly cover the active root layer after penetrating through the drip holes, thus achieving efficient water utilization.

[0003] However, in actual field operations, the precise positioning of drip irrigation tape faces significant challenges due to various factors: on the one hand, the wide mulch width of ultra-wide film cotton fields makes it easy for the drip irrigation tape to deviate from the preset center position when laid manually or mechanically due to uneven tension and differences in film surface flatness; on the other hand, field management activities during the cotton growth cycle (such as weeding, fertilization), wind action, and soil subsidence can further exacerbate the deviation of the drip irrigation tape. If the drip irrigation tape deviates, it will lead to insufficient water for some cotton roots and excessive water for others, resulting in large differences in the growth of cotton within a single film. Ultimately, this leads to large differences in the boll formation rate and opening period of cotton within a single film, affecting the overall yield and fiber quality. Utility Model Content

[0019] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0020] In this disclosure, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the relative positions of the corresponding components in the direction of gravity when they are in use, and "top" and "bottom" refer to the top and bottom relative to the contours of the corresponding components themselves. Furthermore, the terms "first," "second," etc., used in this disclosure are for distinguishing one element from another and do not have sequential or importance implications. In the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements. The above definitions are for explanation and illustration only and should not be construed as limiting this disclosure.

[0021] According to exemplary embodiments of this disclosure, reference is made to Figures 1 to 3 A drip irrigation tape positioning and fixing device suitable for ultra-wide film cotton fields is provided, including a base 1, a fixing component 2 and a positioning component 3. The fixing component 2 is located at the bottom of the base 1 and is used to fix the drip irrigation tape positioning and fixing device suitable for ultra-wide film cotton fields. The positioning component 3 is located at the top of the base 1 and includes a pair of arc-shaped clamping arms 31 and an adjusting mechanism 32 for adjusting the distance between the pair of arc-shaped clamping arms 31. The pair of arc-shaped clamping arms 31 are symmetrically arranged and form a positioning channel 30 for positioning the drip irrigation tape 4 between them.

[0022] Through the above technical solution, in the drip irrigation tape positioning and fixing device for ultra-wide film cotton fields disclosed herein, the base 1 provides an installation carrier for the fixing component 2 and the positioning component 3; the fixing component 2 is set at the bottom of the base 1, stably fixing the entire drip irrigation tape positioning and fixing device for ultra-wide film cotton fields at the furrow position of the ultra-wide film cotton field, preventing the drip irrigation tape positioning and fixing device for ultra-wide film cotton fields from shifting under field operations (such as manual walking, mechanical operation), wind action, or soil settlement; the positioning component 3 is installed on the top of the base 1 and includes a pair of arc-shaped clamping arms 31 and an adjustment mechanism 32, with the pair of arc-shaped clamping arms 31 symmetrically arranged to form a positioning channel 30. This mechanism can initially position and limit the drip irrigation tape 4, placing it in the preset center position. The adjustment mechanism 32 can flexibly adjust the distance between a pair of arc-shaped clamping arms 31 according to the actual diameter of the drip irrigation tape 4, so that the size of the positioning channel 30 matches the size of the drip irrigation tape 4. This ensures that the drip irrigation tape 4 is accurately and stably clamped within the positioning channel 30, effectively solving the problem that the drip irrigation tape 4 is prone to deviating from the preset center position when laid in ultra-wide film cotton fields. This ensures that the roots of each cotton plant can receive water and nutrients evenly, reduces the difference in cotton growth within a single film, increases the boll formation rate, ensures consistent boll opening period, and thus improves the overall yield and fiber quality of cotton.

[0023] According to exemplary embodiments of this disclosure, such as Figure 1 As shown, each of the two arc-shaped clamping arms 31 has a guide portion 311 at its top. The two guide portions 311 are arranged in a "V" shape, and each guide portion 311 is connected to the corresponding arc-shaped clamping arm 31 by an arc-shaped transition. The "V"-shaped guide portion 311 has a good guiding effect. When laying the drip irrigation tape 4, even if there is a certain deviation in the initial position of the drip irrigation tape 4, it can smoothly enter the positioning channel 30 formed by the arc-shaped clamping arm 31 under the guidance of the "V"-shaped guide portion 311, which greatly reduces the alignment difficulty of the drip irrigation tape 4 during installation and improves the installation efficiency of the drip irrigation tape 4. At the same time, the arc-shaped transition connection between the guide portion 311 and the arc-shaped clamping arm 31 can avoid scratch damage to the surface of the drip irrigation tape 4 due to the presence of sharp corners in the structure during the process of the drip irrigation tape 4 entering the positioning channel 30, thus ensuring the integrity of the drip irrigation tape 4.

[0024] According to exemplary embodiments of this disclosure, such as Figure 1 and Figure 2As shown, the base 1 may be provided with a guide rail 11, and the bottom of the arc-shaped clamping arm 31 is provided with a slider that slides with the guide rail 11; the adjustment mechanism 32 is arranged one-to-one with the arc-shaped clamping arm 31, and the adjustment mechanism 32 includes a support base 321, a sleeve 322, a movable push rod 323 and an elastic element 324. The support base 321 is fixedly installed on the upper surface of the base 1, and the sleeve 322 is threaded through the support base 321. The movable push rod 323 is slidably installed inside the sleeve 322. The movable push rod 323 is provided with an elastic element 324. The elastic element 324 is used to move the end of the movable push rod 323 close to the arc-shaped clamping arm 31 toward the arc-shaped clamping arm 31 and abut against the arc-shaped clamping arm 31.

[0025] In the above technical solution, the elastic element 324 can be a spring or an elastic rubber sleeve, and this disclosure does not make specific restrictions on it; the arc-shaped clamping arm 31 slides with the guide rail 11 through the slider, so that the arc-shaped clamping arm 31 can move stably and smoothly along the guide rail 11 when adjusting the spacing, avoiding the arc-shaped clamping arm 31 from deviating or getting stuck during the movement, ensuring that the positioning channel 30 is always in the preset positioning direction, and further improving the positioning accuracy of the drip irrigation tape 4.

[0026] In this disclosure, such as Figure 2 As shown, the adjustment mechanism 32 includes a support base 321, a sleeve 322, a movable push rod 323, and an elastic element 324. The support base 321 is fixed on the base body 1, providing stable support for the entire adjustment mechanism 32. The sleeve 322 is threaded through the support base 321. By rotating the sleeve 322, its position on the support base 321 can be adjusted, thus providing a basis for adjusting the movable push rod 323. The movable push rod 323 is slidably disposed within the sleeve 322. The elastic element 324 can push the end of the movable push rod 323 close to the arc-shaped clamping arm 31 to abut against the arc-shaped clamping arm 31. Through this arrangement, the elastic force of the elastic element 324 can be used to ensure that the movable push rod 323 always applies a stable abutting force to the arc-shaped clamping arm 31, thereby stabilizing the arc-shaped clamping arm 31 in the adjusted position, ensuring the stability of the positioning channel 30 dimensions, and preventing the arc-shaped clamping arm 31 from shifting due to external vibrations or other factors, thereby ensuring the stability of the positioning of the drip irrigation tape 4.

[0027] Furthermore, with the above settings, when it is necessary to adjust the spacing of the arc-shaped clamping arms 31, the position of the movable top rod 323 can be adjusted simply by rotating the sleeve 322. This makes the operation simple and convenient, and can adapt to the positioning requirements of drip irrigation tapes 4 of different diameters, thus improving the versatility of the device.

[0028] According to exemplary embodiments of this disclosure, such as Figure 2As shown, a tapered abutment 325 may be provided on one end of the movable push rod 323 near the arc-shaped clamping arm 31; an elastic element 324 is sleeved on the movable push rod 323, and one end of the elastic element 324 abuts against the sleeve 322, and the other end abuts against the large end of the tapered abutment 325, so that the small end of the tapered abutment 325 abuts against the outer arc surface of the corresponding arc-shaped clamping arm 31. By setting it in this way, the contact area between the movable push rod 323 and the arc-shaped clamping arm 31 can be reduced, the friction between the two can be reduced, and the arc-shaped clamping arm 31 can slide more smoothly on the guide rail 11, reducing the adjustment resistance.

[0029] In the above technical solution, the elastic element 324 is sleeved on the movable top rod 323, and its two ends abut against the sleeve 322 and the large end of the conical abutment part 325, respectively. This installation method can ensure that the elastic element 324 always moves along the axial direction of the movable top rod 323 during the force extension and contraction process, avoid the elastic element 324 from being deviated or twisted, and ensure that the elastic element 324 applies a stable elastic force to the movable top rod 323, thereby ensuring the continuity and stability of the abutment force of the movable top rod 323 against the arc-shaped clamping arm 31.

[0030] According to exemplary embodiments of this disclosure, such as Figure 2 As shown, multiple elastic protrusions 33 are spaced apart on the inner arc surface of the arc-shaped clamping arm 31. The elastic protrusions 33 can be made of a material with a certain degree of elasticity (such as silicone or nitrile rubber). When the drip irrigation tape 4 is clamped in the positioning channel 30, the elastic protrusions 33 will form flexible contact with the surface of the drip irrigation tape 4. In this way, the elastic protrusions 33 can increase the friction between the arc-shaped clamping arm 31 and the drip irrigation tape 4, further preventing the drip irrigation tape 4 from sliding axially or shifting radially in the positioning channel 30. Especially under external force interference such as wind blowing or touch by field workers, it can maintain the stability of the positioning of the drip irrigation tape 4. In addition, the flexible elastic protrusions 33 can prevent the inner arc surface of the arc-shaped clamping arm 31 from forming rigid compression with the surface of the drip irrigation tape 4, preventing the drip irrigation tape 4 from being damaged on the surface or deformed in the internal flow channel due to long-term clamping force, ensuring the normal water delivery function of the drip irrigation tape 4 and extending its service life.

[0031] According to exemplary embodiments of this disclosure, such as Figure 1 and Figure 2 As shown, the fixing component 2 may include at least two anchors 21, which are spaced apart at the bottom of the base 1. Each anchor 21 includes a body, which includes a connecting section 211, a middle section 212 and a spike section 213 connected in sequence. The connecting section 211 is threaded to the bottom of the base 1. The middle section 212 is provided with multiple rows of barbs 22 arranged in a ring. Each row of barbs 22 is arranged from top to bottom at intervals, and a water passage 23 is formed between two adjacent rows of barbs 22.

[0032] In the above technical solution, at least two spaced anchors 21 can be inserted into the soil from different positions at the bottom of the base 1 to form multi-point fixation. Compared with single-point fixation, this can significantly improve the overall anti-tipping ability of the device and prevent the device from tilting or shifting due to wind, soil settlement or vibration from field machinery operations. This provides a stable foundation for the precise positioning of the drip irrigation tape 4. The sharp structure of the spiked section 213 can reduce the resistance when the anchor 21 is inserted into the soil, making it easier for operators to quickly fix the device in the furrow and improve installation efficiency. The threaded connection structure between the connecting section 211 and the bottom of the base 1 facilitates the disassembly and replacement of the anchor 21. When the anchor 21 rusts or is damaged due to long-term use, the anchor 21 can be replaced individually without replacing the entire device.

[0033] In this disclosure, due to the multiple rows of barbs 22, when the anchor 21 is inserted into the soil, the barbs 22 will form a reverse interlock with the soil, effectively preventing the anchor 21 from coming off upwards under soil weight settlement, rainwater erosion, or external pulling, further enhancing the stability of the device. At the same time, the water passage 23 formed between two adjacent rows of barbs 22 can prevent the anchor 21 from blocking the water infiltration path inside the soil after it is inserted into the soil, ensuring that the water dripped from the drip irrigation tape 4 can diffuse normally in the soil, cover the active layer of cotton roots, and ensure water use efficiency.

[0034] According to exemplary embodiments of this disclosure, such as Figure 2 and Figure 3 As shown, the middle section 212 is constructed as an hourglass-shaped column structure that is wide at both ends and narrow in the middle. Due to the hourglass shape, when the anchor 21 is inserted into the soil, the wider ends can form a larger contact area and interlocking force with the soil. Compared with the traditional cylindrical middle section 212, this can further enhance the pull-out resistance and toppling resistance of the anchor 21 in the soil, reduce the risk of the anchor 21 shifting due to soil loosening or external forces, and improve the overall stability of the device. The narrow middle section will not excessively compress the soil, avoid the compaction of soil particles, and ensure the soil's aeration and water permeability, providing a good soil environment for cotton root growth, indirectly promoting cotton growth, and increasing yield and fiber quality.

[0035] In addition, the combination of the hourglass-shaped structure with the barbs 22 and the water passages 23 can enhance the fixing effect without affecting water infiltration and soil permeability, thus achieving synergistic optimization of functions.

[0036] According to exemplary embodiments of this disclosure, referring to Figures 1 to 3The base 1 has a first side 101 and a second side 102 arranged opposite to each other, spaced apart along the axial direction of the positioning channel 30. One of the first side 101 and the second side 102 has a slot 12, and the other has a locking block 13 that engages with the slot 12. Through the engagement of the slot 12 and the locking block 13, multiple drip irrigation tape positioning and fixing devices suitable for ultra-wide film cotton fields can be sequentially spliced ​​along the axial direction of the drip irrigation tape 4 to form a continuous positioning system.

[0037] In the above technical solution, the continuous splicing of multiple drip irrigation tape positioning and fixing devices suitable for ultra-wide film cotton fields can provide full and uniform positioning support for the drip irrigation tape 4, avoiding the sagging or displacement of the middle part of the drip irrigation tape 4 due to excessively large intervals between individual drip irrigation tape positioning and fixing devices suitable for ultra-wide film cotton fields. This ensures that the drip irrigation tape 4 is always positioned in the furrow in the middle of the two rows of cotton plants, guaranteeing accurate water coverage of the active root layer. In addition, the splicing structure adopts a snap-fit ​​method, which is simple and quick to operate. Operators can complete the assembly of multiple devices without the need for additional tools, greatly improving the efficiency of field installation. At the same time, it is convenient to flexibly adjust the number of drip irrigation tape positioning and fixing devices suitable for ultra-wide film cotton fields according to the laying length of the drip irrigation tape 4 later.

[0038] According to exemplary embodiments of this disclosure, such as Figure 1 and Figure 2 As shown, the base 1 has a sliding groove 14, and the locking block 13 includes a sliding section 131 and a locking section 132 connected to each other. The width of the sliding section 131 is smaller than the width of the sliding groove 14, and the sliding section 131 is slidably connected to the sliding groove 14. The width of the locking section 132 is larger than the width of the sliding groove 14, and the locking section 132 can be locked to the sliding groove 14. The sliding groove 14 and the locking groove 12 are both constructed as U-shaped structures, and their cross-sectional dimensions are the same. By setting the chute 14, when the drip irrigation tape positioning and fixing device suitable for ultra-wide film cotton fields is used alone, the locking block 13 can be slid into the chute 14 and the locking section 132 can be locked with the chute 14 to store the locking block 13. When the drip irrigation tape positioning and fixing device suitable for ultra-wide film cotton fields needs to be spliced ​​and combined, the locking block 13 can be pulled out from the chute 14 and locked with the locking slot 12 of the adjacent drip irrigation tape positioning and fixing device suitable for ultra-wide film cotton fields. In this way, the flexibility and convenience of using the drip irrigation tape positioning and fixing device suitable for ultra-wide film cotton fields are improved.

[0039] Based on the above technical solutions, this disclosure also provides a drip irrigation device, including a drip irrigation tape 4 and the aforementioned drip irrigation tape positioning and fixing device suitable for ultra-wide film cotton fields. This drip irrigation device possesses all the beneficial effects of the aforementioned drip irrigation tape positioning and fixing device suitable for ultra-wide film cotton fields, which will not be repeated here.

[0040] like Figures 1 to 3 As shown, this drip irrigation tape positioning and fixing device, applicable to ultra-wide film cotton fields, is used by first adjusting the distance between the two arc-shaped clamping arms 31 according to the diameter of the drip irrigation tape 4 to be laid, by rotating the sleeve 322 of the adjusting mechanism 32, so that the positioning channel 30 is adapted to the size of the drip irrigation tape 4; then, at the preset position in the furrow of the ultra-wide film cotton field (the middle of two rows of cotton plants), the anchor nail 21 at the bottom of the base 1 is aligned with the ground, and by pressing or tapping the top of the base 1, the spiked section 213 of the anchor nail 21 penetrates the film and inserts into the soil, and the anchor nail 21... The barbs 22 engage with the soil, thus fixing the drip irrigation tape positioning and fixing device suitable for ultra-wide film cotton fields. Then, the drip irrigation tape 4 is placed into the positioning channel 30 along the "V"-shaped guide part 311 at the top of the arc-shaped clamping arm 31. The guide part 311 guides the drip irrigation tape 4 into precise position. At this time, the elastic element 324 pushes the conical abutment part 325 of the movable top rod 323 to press against the arc-shaped clamping arm 31. The arc-shaped clamping arm 31 self-adjusts along the guide rail 11, so that the elastic protrusion 33 on the inner arc surface flexibly fits the drip irrigation tape 4, completing the stable clamping of the drip irrigation tape 4.

[0041] If the drip irrigation tape 4 is laid for a long length, the bases 1 of adjacent drip irrigation tape positioning and fixing devices suitable for ultra-wide film cotton fields can be brought closer together. The locking block 13 of one of the drip irrigation tape positioning and fixing devices suitable for ultra-wide film cotton fields can be slid, allowing the locking section 132 of the locking block 13 to insert into the slot 12 of the other drip irrigation tape positioning and fixing device suitable for ultra-wide film cotton fields, thus splicing the two drip irrigation tape positioning and fixing devices suitable for ultra-wide film cotton fields. This step is repeated to splice all drip irrigation tape positioning and fixing devices suitable for ultra-wide film cotton fields along the axis of the drip irrigation tape 4 into a continuous positioning system, ensuring that the drip irrigation tape 4 is in the preset furrow position throughout its length.

[0042] The preferred embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0043] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0044] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
