Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, and in particular to an automatic recycling and winding machine for cotton seedling drip irrigation tape. Background Technology

[0002] Drip irrigation technology is widely used in cotton cultivation, playing a vital role in water conservation and yield increase. Timely recycling of drip irrigation tape after the cotton seedling stage is crucial. On the one hand, drip irrigation tape left in the field can damage soil structure, affecting the subsequent growth of cotton and other crops, and causing "white pollution," which is detrimental to sustainable agricultural development. On the other hand, recycled drip irrigation tape can be reused after processing, significantly reducing planting costs. Traditional manual recycling methods are extremely labor-intensive and inefficient, requiring substantial manpower and time in large-scale cotton field operations, resulting in high costs. The automatic drip irrigation tape recycling and winding machine for cotton seedlings has emerged to address this issue, aiming to efficiently solve the drip irrigation tape recycling problem through mechanized and automated operations.

[0003] However, relying solely on the rotation of the reel during drip irrigation tape winding and recycling can easily lead to localized accumulation or uneven winding of the tape on the reel, forming "bulges" or "eccentric rolls." This affects the efficiency of subsequent transportation, storage, and recycling, and can even cause damage to the drip irrigation tape due to compression. In addition, traditional recycling and winding machines use fixed tension winding, which cannot dynamically adjust the tension according to changes in working conditions such as the increase in roll diameter and the increase in drip irrigation tape length during the winding process. This can result in problems such as insufficient tension in the early stage leading to loose roll material, and excessive tension in the later stage causing the drip irrigation tape to break. Utility Model Content

[0004] The purpose of this invention is to solve the problems of local accumulation of existing drip irrigation tape during recycling and winding, and the problems of insufficient tension in the early stage leading to loose rolls and excessive tension in the later stage causing the drip irrigation tape to break due to fixed winding tension. Therefore, an automatic recycling and winding machine for cotton seedling drip irrigation tape is proposed.

[0005] To achieve the above objectives, the present invention employs the following technology: an automatic recycling and winding machine for cotton seedling drip irrigation tape, comprising a mobile trolley, wherein a winding cylinder is mounted on the mobile trolley via a bracket, and the winding cylinder is able to rotate on the bracket via a drive mechanism to perform winding and recycling of the drip irrigation tape;

[0006] The support is equipped with a guide mechanism located on the movement path of the drip irrigation tape to prevent the drip irrigation tape from accumulating locally on the winding cylinder. The guide mechanism includes an adjustment component that can adaptively adjust the winding tension of the drip irrigation tape.

[0007] As a further description of the above technical solution: the guiding mechanism also includes a mounting bracket disposed on the adjusting component, and the mounting bracket has a wheel assembly that can reciprocate along the axial direction of the winding cylinder driven by a reciprocating module.

[0008] As a further description of the above technical solution: the reciprocating module includes a servo motor mounted on a mounting frame, a screw fixedly connected to its output end, and a slide that is threadedly engaged with the screw. The mounting frame is also provided with a guide rail that engages with the slide.

[0009] As a further description of the above technical solution: the wheel assembly includes a mounting plate that is detachably mounted on the slide, and two guide wheels are provided on the mounting plate through two clamps arranged perpendicularly to each other.

[0010] As a further description of the above technical solution: the adjustment component includes a mounting base fixed on the bracket, a slider connected to the mounting frame is slidably connected inside the mounting base, a limiting rod is provided on the slider and passes through the mounting base, and an adjustment spring is sleeved on the limiting rod.

[0011] As a further description of the above technical solution: the cleaning component includes a fixed frame mounted on a mobile trolley, and two parallel brush rollers are mounted on the fixed frame.

[0012] As a further description of the above technical solution: the two ends of the brush roller are provided with connecting heads through the mounting groove, and the connecting heads can be extended and retracted along the brush roller axis within the mounting groove by means of a return spring;

[0013] The mounting bracket has a socket that mates with the connecting end.

[0014] As a further description of the above technical solution: the driving mechanism includes a motor set mounted on the mobile trolley, and a transmission belt is provided on the output end of the motor set via a drive wheel;

[0015] The winding drum is equipped with a driven pulley that cooperates with the transmission belt.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0017] By reciprocating along the axis of the winding cylinder using the wheel assembly, the drip irrigation tape is evenly spread on the surface of the winding cylinder at a set interval, avoiding the formation of "bulges" or "eccentric rolls" due to concentrated winding in a certain area. This ensures that the roll surface is flat, making it less likely to scatter during subsequent transportation. The regular roll shape facilitates subsequent automated cleaning, sorting, and recycling, reducing manual handling costs.

[0018] The winding tension is adaptively adjusted by adjusting the components. In the early stage of winding, the tension is small to prevent the drip irrigation tape from being stretched and damaged. In the later stage of winding, the tension gradually increases with the increase of the roll diameter to ensure that the roll material is uniformly compact from the inside to the outside, avoiding "loose outer layer and flat inner layer".

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-9 This embodiment provides an automatic recycling and winding machine for cotton seedling drip irrigation tape, including a mobile trolley 1. A winding cylinder 3 is mounted on the mobile trolley 1 via a bracket 2. The winding cylinder 3 can rotate on the bracket 2 via a drive mechanism 4 to wind and recycle the drip irrigation tape. The drive mechanism 4 includes a motor unit 41 mounted on the mobile trolley 1. A transmission belt 43 is mounted on the output end of the motor unit 41 via a drive wheel 42. A driven wheel that cooperates with the transmission belt 43 is mounted on the winding cylinder 3.

[0032] In this invention, the winding machine is moved to the area where the drip irrigation tape is to be recycled. The position is adjusted by the wheels of the moving trolley 1 to ensure that the winding cylinder 3 is aligned with the laying direction of the drip irrigation tape. The free end of the drip irrigation tape is manually fixed to one end of the winding cylinder 3 (e.g., by buckle, bolt or manual) and wound several times to ensure that the starting end is firm and to avoid slippage during winding. The output end of the motor unit 41 drives the drive wheel 42 to rotate synchronously. The drive wheel 42 transmits the rotational power to the driven wheel of the winding cylinder 3 through the friction of the transmission belt 43. The driven wheel drives the winding cylinder 3 to rotate at high speed under the support of the bracket 2, forming winding power. When the winding cylinder 3 rotates, the drip irrigation tape is wound layer by layer on its surface. When the winding cylinder 3 is full of drip irrigation tape (e.g., reaching the preset roll diameter or the motor load current increases), the operator turns off the motor unit 41, and the equipment stops rotating.

[0033] The winding drum 3 is detachably mounted on the top of the bracket 2 via a bearing seat. When the winding drum 3 is fully wound, the fully wound winding drum 3 is removed, and the empty drum is replaced before continuing the operation.

[0034] Specifically, such as Figures 2-4As shown, a guide mechanism 5 is provided on the support 2 at a position on the movement path of the drip irrigation tape to prevent the drip irrigation tape from accumulating locally on the winding cylinder 3. The guide mechanism 5 includes a mounting frame 51 provided on the adjustment component 54. A wheel assembly 53 is driven by a reciprocating module 52 on the mounting frame 51 to reciprocate along the axial direction of the winding cylinder 3. The reciprocating module 52 includes a servo motor 521 provided on the mounting frame 51. A screw 522 is fixedly connected to its output end, and a slide 523 is provided on the screw 522 to be threadedly engaged with it. A guide rail 524 that engages with the slide 523 is also provided on the mounting frame 51. The wheel assembly 53 includes a mounting plate 531 that is detachably mounted on the slide 523. Two guide wheels 533 are provided on the mounting plate 531 through two clamps 532 arranged perpendicularly to each other.

[0035] The servo motor 521 starts after receiving the command from the control system. The output shaft drives the screw 522 to rotate. The screw 522 and the slide 523 are connected by a thread to convert the rotational motion into the linear reciprocating motion of the slide 523 along the guide rail 524. The guide rail 524 plays a guiding and supporting role to ensure motion accuracy. The servo motor 521 can control the movement direction of the slide 523 by forward and reverse rotation.

[0036] It should be noted that both the servo motor 521 and the motor assembly 41 of the drive mechanism 4 are controlled by an external PLC control structure. An encoder is installed on the servo motor 521. With the existing PLC control system, the forward and reverse rotation control of the servo motor 521 can be realized, thereby controlling the reciprocating stroke of the wheel assembly 53. The drip irrigation tape passes between the two guide wheels 533. When the drip irrigation tape changes angle as the diameter of the winding cylinder 3 increases, the guide wheels 533 can rotate freely around the mounting plate 531 or have their angles finely adjusted by the bearings to maintain tangential contact with the drip irrigation tape and reduce frictional resistance. Through the reciprocating motion of the wheel assembly 53, the drip irrigation tape is forcibly guided to different positions on the winding cylinder 3 to avoid concentration in the middle or at the edge, forming a tight and neat roll structure.

[0037] Specifically, such as Figure 2 and Figure 5 As shown, the guide mechanism 5 also includes an adjustment component 54 that can adaptively adjust the winding tension of the drip irrigation tape. The adjustment component 54 includes a mounting base 541 fixed on the bracket 2. A slider 542 connected to the mounting bracket 51 is slidably connected inside the mounting base 541. A limiting rod 543 that passes through the mounting base 541 is provided on the slider 542, and an adjustment spring 544 is sleeved on the limiting rod 543.

[0038] The mounting base 541 is fixed on the bracket 2, and the slider 542 slides within the mounting base 541, connecting the mounting bracket 51 and the slider 542. This allows the entire wheel assembly 53 to move with the slider 542. When the drip irrigation tape is not under stress, the adjusting spring 544 pushes the slider 542 to the lowest position, and the wheel assembly 53 is in a lower position. The winding path of the drip irrigation tape is shorter, and the tension is lower. As the diameter of the winding cylinder 3 increases, the upward reaction force of the drip irrigation tape on the guide wheel 533 increases, compressing the adjusting spring 544. The slider 542 moves upward along the mounting base 541, the wheel assembly 53 rises, the winding angle of the drip irrigation tape changes, and the resistance increases, thereby automatically increasing the tension and realizing adaptive adjustment of the winding tension. No sensors, controllers, or other electronic components are required. Tension control is achieved solely through the spring and slider mechanism, reducing costs and maintenance complexity, and making it suitable for harsh field environments.

[0039] It should be noted that the limit rod 543 has a nut limiter at the top and its bottom is also threadedly connected to the slider 542, which makes it easy to remove the limit rod 543 from the slider 542, thereby facilitating the replacement of the adjusting spring 544 and ensuring that the adjusting spring 544 can quickly respond to the slight fluctuations in the tension of the drip irrigation tape.

[0040] Specifically, such as Figure 1 and Figure 6 As shown, the cleaning component 6 includes a fixed frame 61 mounted on the mobile trolley 1. The fixed frame 61 is provided with two parallel brush rollers 62. Both ends of the brush rollers 62 are provided with connecting ends 622 through mounting grooves 621. The connecting ends 622 can extend and retract along the axial direction of the brush rollers 62 within the mounting grooves 621 by means of a return spring 623. The fixed frame 61 is provided with insertion holes that cooperate with the connecting ends 622.

[0041] Two parallel brush rollers 62 are mounted on a fixed frame 61, and the drip irrigation tape passes between the two brush rollers 62 during the retrieval process. The bristles on the surface of the brush rollers 62 contact the surface of the drip irrigation tape. As the drip irrigation tape moves, the bristles scrape or brush off surface impurities through friction, thus completing the cleaning work.

[0042] The connecting end 622 is installed in the mounting grooves 621 at both ends of the brush roller 62 via a return spring 623. The spring is initially compressed, applying an outward pushing force to the connecting end 622. The insertion hole on the fixing bracket 61 matches the size of the connecting end 622. During installation, the connecting end 622 is aligned with the insertion hole and pressed to make the connecting end 622 fit tightly against the inner wall of the insertion hole, achieving mechanical locking. During disassembly, the connecting ends 622 at both ends are pressed inward along the axial direction of the brush roller 62 to compress the return spring 623, causing the end to exit the insertion hole, and the brush roller 62 can be quickly removed. The quick disassembly and assembly of the brush roller 62 makes it convenient for maintenance personnel to regularly clean the clogged water spray holes or replace worn bristles.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
