Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a device for splicing drip irrigation tape and a mulching operation device. Background Technology

[0002] Mulching devices are commonly used agricultural machinery, primarily for laying mulch film and drip irrigation tape on field surfaces. After the drip irrigation tape is used up, the tape reel needs to be manually installed, passing the starting end of the tape through the guide rollers and connecting it to the end of the previous tape to complete the initial setup. Tape splicing is typically done via heat fusion or adhesive tape, which is usually complex and time-consuming, making it difficult to ensure the continuity of the drip irrigation tape laying operation and resulting in low efficiency. Therefore, it is necessary to propose a drip irrigation tape splicing device and a mulching device to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to provide a splicing device and a film covering device for drip irrigation tape, so as to solve the problems that the existing drip irrigation tape splicing methods are relatively complicated and time-consuming, cannot guarantee the continuity of drip irrigation tape laying operations, and have low work efficiency.

[0004] In a first aspect, the present invention provides a splicing device for drip irrigation tape, comprising: a frame, a drip irrigation tape roll support, and a quick-connect coupling positioning assembly;

[0005] Two drip irrigation tape roll supports are symmetrically arranged on the frame, and the drip irrigation tape roll supports are provided with mounting grooves for installing drip irrigation tape rolls;

[0006] The quick-connector positioning assembly includes a capturing device located below the drip tape roll support, and the capturing device can switch between a clamping state and an open state;

[0007] When the capturing device is in the clamping state, a clamping through hole extending vertically is formed on the capturing device; the diameter of the clamping through hole is greater than or equal to the diameter of the drip irrigation tape, and less than the maximum diameter of the second quick connector at the end of the drip irrigation tape; when the capturing device switches from the open state to the clamping state, it can gather the drip irrigation tape located on the drip irrigation tape roll support into the clamping through hole, and as the drip irrigation tape continues to be laid, the second quick connector at the end of the drip irrigation tape is finally clamped and fixed; when the spare drip irrigation tape roll is installed on the drip irrigation tape roll support and descends to the bottom of the installation groove, the first quick connector with the vertically downward-facing end of the drip irrigation tape on the spare drip irrigation tape roll is connected by collision with the second quick connector at the end of the drip irrigation tape in the clamping through hole.

[0008] Furthermore, the mounting groove includes a receiving structure located at the top and a vertical sliding groove connected to the bottom of the receiving structure. The top of the receiving structure is open, the bottom of the receiving structure communicates with the top of the vertical sliding groove, and the bottom of the vertical sliding groove is closed.

[0009] The quick-connector positioning assembly also includes a drive assembly, which is mounted on the frame and is used to drive the capture device to switch between a clamping state and an open state.

[0010] Furthermore, the capturing device includes a first clamping rod group and a second clamping rod group, wherein the first clamping rod group and the second clamping rod group each include two clamping rods arranged in parallel, and the first clamping rod group and the second clamping rod group are perpendicular to each other;

[0011] The driving component is used to drive the clamps of the first clamping roller group and the second clamping roller group to move towards the central region to form the clamping through hole;

[0012] The inner sides of the clamps of the first clamping rod group and the second clamping rod group are respectively provided with quarter-funnel-shaped grooves. The first clamping rod group and the second clamping rod group form the clamping through hole by four quarter-funnel-shaped grooves. The shape of the clamping through hole matches the external shape of the second quick connector.

[0013] Furthermore, the capturing device includes a first arc-shaped clamp and a second arc-shaped clamp, both of which include an arc-shaped central portion and extension portions extending from both sides of the central portion.

[0014] The center portions of the first arc-shaped clamp and the second arc-shaped clamp are arranged opposite each other to form a clamping ring between the first arc-shaped clamp and the second arc-shaped clamp.

[0015] When the capturing device switches from the open state to the clamping state, the first arc-shaped clamp and the second arc-shaped clamp move closer to each other, causing the clamping ring to shrink to form the clamping through hole.

[0016] Furthermore, the drip irrigation tape roll includes a roll and drip irrigation tape. The roll is provided with a rotating shaft, and the drip irrigation tape is wound around the roll. The first end of the drip irrigation tape is provided with a first quick connector, and the last end is provided with a second quick connector that can mate with the first quick connector. The first quick connector is a male connector, and the second quick connector is a female connector. The female connector is provided with a funnel-shaped guide portion to facilitate the insertion of the male connector.

[0017] Furthermore, the maximum outer diameter of the second quick-connect fitting is greater than the outer diameter of the drip irrigation tape.

[0018] Furthermore, the reel is provided with a quick-release latch for securing the first quick-connect connector.

[0019] Furthermore, the roll is provided with baffles at both ends along the axial direction, and the baffles are provided with a first positioning plane; when the drip irrigation tape roll in the standby state is placed on a horizontal surface through the first positioning plane, the first quick connector fixed on the quick-release buckle is vertically downward.

[0020] Secondly, the present invention provides a film covering operation device, including the above-described splicing device for drip irrigation tape.

[0021] Furthermore, the mulching operation device also includes a support vehicle, which is equipped with a storage position and a robotic arm. The bottom surface of the storage position is provided with a second positioning plane that is adapted to the first positioning plane for storing spare drip irrigation tape rolls. The support vehicle can be positioned and moved to a designated position, and the robotic arm can grab the spare drip irrigation tape rolls and install them onto the drip irrigation tape roll bracket.

[0022] The present invention has the following beneficial effects: The drip irrigation tape splicing device and mulching operation device of the present invention can switch from an open state to a clamping state through a capturing device, and gather the drip irrigation tape located on the drip irrigation tape roll support into the clamping through hole. As the drip irrigation tape continues to be laid, the second quick connector at the end of the drip irrigation tape is finally clamped and fixed. When the spare drip irrigation tape roll is installed on the drip irrigation tape roll support and descends to the bottom of the vertical slide, the first quick connector at the vertically downward end of the drip irrigation tape on the spare drip irrigation tape roll is connected by collision with the second quick connector at the end of the drip irrigation tape in the clamping through hole. The drip irrigation tape can be spliced ​​without stopping the current drip irrigation tape laying operation, which can ensure the continuity of the drip irrigation tape laying operation and improve the drip irrigation tape laying efficiency.

Detailed Implementation

[0032] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore merely examples and should not be used to limit the scope of protection of the present invention. It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning understood by those skilled in the art to which this invention pertains.

[0033] Please see Figures 1 to 6 This invention provides a splicing device for drip irrigation tape, including: a frame 1, a drip irrigation tape roll support 2, and a quick-connect coupling positioning assembly.

[0034] Two drip irrigation tape roll supports 2 are symmetrically arranged on the frame 1. The frame 1 serves as the basic support structure for the entire device, ensuring the stable installation and operation of all components. The drip irrigation tape roll supports 2 are provided with mounting grooves 4 for installing drip irrigation tape rolls 3. The attached drawings schematically show a Y-shaped mounting groove 4, but this application is not limited to this. The Y-shaped mounting groove 4 includes a receiving structure 5 located at the top and a vertical slide 6 connected to the bottom of the receiving structure 5. The top of the receiving structure 5 is open to receive the drip irrigation tape roll 3, and the bottom of the receiving structure 5 communicates with the top of the vertical slide 6, which is closed at the bottom. Taking the Y-shaped mounting groove 4 as an example, the receiving structure 5 can be funnel-shaped to facilitate the insertion of the drip irrigation tape roll 3. This application is not limited to this; for example, the receiving structure 5 can also be U-shaped, or it can be a funnel shape with certain curvatures on both sides. The bottom of the receiving structure 5 communicates with the vertical slide 6, thereby ensuring that the drip irrigation tape roll 3 can stably slide down vertically to the working position after installation.

[0035] The quick-connect fitting positioning assembly includes a capturing device 9 and a driving assembly 10. The capturing device 9 is located below the drip tape roll support 2, and the driving assembly 10 is mounted on the frame 1. The driving assembly 10 is used to drive the capturing device 9 to switch between a clamping state and an open state. When the capturing device 9 is in the clamping state, a clamping through hole extending vertically is formed on the capturing device 9. The diameter of the clamping through hole is greater than or equal to the diameter of the drip tape 11, and less than the maximum diameter of the second quick-connect fitting 8 at the end of the drip tape 11. When the capturing device 9 switches from the open state to the clamping state, it can position the quick-connect fitting located at the end of the drip tape 11. The drip irrigation tape 11 on the drip irrigation tape roll bracket 2 is drawn into the clamping through hole. As the drip irrigation tape 11 continues to be laid under the action of the guide wheel 12, the second quick connector 8 at the end of the drip irrigation tape 11 is finally clamped and fixed, so as to facilitate the connection with the tape body of the next drip irrigation tape without the need to readjust the guide wheel of the drip irrigation tape. When the spare drip irrigation tape roll 3 is installed on the drip irrigation tape roll bracket 2 and descends to the bottom of the vertical slide 6, the first quick connector 7 with the vertically downward end of the drip irrigation tape 11 on the spare drip irrigation tape roll 3 is connected by collision with the second quick connector 8 at the end of the drip irrigation tape 11 in the clamping through hole.

[0036] As an optional implementation, the capturing device 9 includes a first clamping rod group 14 and a second clamping rod group 15, each of which includes two parallel clamping rods and is perpendicular to each other; the driving component 10 is used to drive the clamping rods of the first clamping rod group 14 and the second clamping rod group 15 to move towards the middle area to form a clamping through hole.

[0037] Optionally, the inner sides of the clamps of the first clamping roller assembly 14 and the second clamping roller assembly 15 are respectively provided with quarter-funnel-shaped grooves 16. The first clamping roller assembly 14 and the second clamping roller assembly 15 form a funnel-shaped clamping through hole through the four quarter-funnel-shaped grooves 16, and the shape of the clamping through hole matches the external shape of the second quick connector 8. In this case, the minimum diameter of the clamping through hole (i.e., the diameter at the bottom of the funnel-shaped clamping through hole) is greater than or equal to the diameter of the drip irrigation tape 11, and less than the maximum diameter of the second quick connector 8 at the end of the drip irrigation tape 11. By using the combination of the first clamping roller assembly 14 and the second clamping roller assembly 15, and forming a clamping through hole through the four quarter-funnel-shaped grooves 16 that matches the external shape of the second quick connector 8, the capturing device clamps the drip irrigation tape more firmly and causes less damage to the drip irrigation tape.

[0038] Specifically, the drive assembly 10 can employ an existing electric or pneumatic drive device to drive the first clamping roller group 14 and the second clamping roller group 15. If the drive assembly 10 uses an electric drive device, its structure may include a motor, a transmission mechanism, a control unit, etc. A motor with appropriate power and speed, such as a stepper motor or a servo motor, is selected to provide driving force. The transmission mechanism may include a reduction gear, a lead screw and nut pair, or a synchronous pulley, etc., to convert the rotational motion of the motor into the linear motion of the clamping rollers. For example, the motor can drive the lead screw to rotate through the reduction gear, and the lead screw and nut pair will drive the clamping rollers to move linearly. The control unit may consist of a controller and sensors to receive commands, control the start and stop, speed and direction of the motor, and monitor the position and status of the clamping rollers. When it is necessary to capture the second quick connector 8 at the end of the drip irrigation tape, the control unit sends a command to the motor. The motor starts and drives the clamping rollers of the first clamping roller group 14 and the second clamping roller group 15 to move towards the middle area through the transmission mechanism. The quarter-funnel-shaped grooves 16 on the inner side of the clamping rollers gradually approach and align, forming a clamping through hole that matches the external shape of the second quick connector 8. As the drip irrigation tape 11 continues to be laid under the action of the guide wheel 12, the second quick connector 8 is finally clamped in the clamping through hole, completing the capture process.

[0039] If the drive assembly 10 uses a pneumatic drive device, its structure may include a cylinder, a pneumatic control element, a control unit, etc. A cylinder with suitable stroke and thrust is selected as the actuator. The pneumatic control element may include a solenoid valve, air pipe, connector, etc., used to control the cylinder's air intake, exhaust, and reversing. The control unit may consist of a controller and sensors, used to receive commands, control the solenoid valve's opening and closing, and monitor the cylinder's position and status. When it is necessary to capture the second quick-connect connector 8 at the end of the drip irrigation tape, the control unit sends a command to the solenoid valve. The solenoid valve switches its state, the cylinder intakes air, and pushes the clamping roller towards the central area. The quarter-funnel-shaped groove 16 on the inner side of the clamping roller gradually approaches and aligns, forming a clamping through hole. As the drip irrigation tape 11 continues to be laid under the action of the guide wheel 12, the second quick-connect connector 8 is finally clamped in the clamping through hole, completing the capture process.

[0040] As an alternative implementation, the capturing device 9 includes a first arc-shaped clamp 17 and a second arc-shaped clamp 18. Both the first arc-shaped clamp 17 and the second arc-shaped clamp 18 include an arc-shaped central portion and extension portions extending from both sides of the central portion. The central portions of the first arc-shaped clamp 17 and the second arc-shaped clamp 18 are arranged opposite each other, thereby forming a clamping ring between them. When the capturing device 9 switches from an open state to a clamping state, the first arc-shaped clamp 17 and the second arc-shaped clamp 18 move closer to each other, causing the extension portions of the first arc-shaped clamp 17 and the second arc-shaped clamp 18 to intersect or further intersect. Simultaneously, the clamping ring formed by the arc-shaped central portion shrinks to form a clamping through-hole. Using the combination of the first arc-shaped clamp 17 and the second arc-shaped clamp 18, the clamping through-hole is formed through relative movement and position exchange between them, simplifying the structure and improving operational flexibility.

[0041] In the design of the capturing device 9, which employs a first arc-shaped clamp 17 and a second arc-shaped clamp 18, the structure of the drive assembly 10 can drive the two arc-shaped clamps to approach each other and exchange positions using existing electric or pneumatic methods to form a clamping through-hole. Specifically, the drive device may include a motor or cylinder as a power source, transmitting power to the first arc-shaped clamp 17 and the second arc-shaped clamp 18 through a transmission mechanism such as a linkage, gear, or cam. When it is necessary to capture the second quick-connect connector 8 at the end of the drip irrigation tape, the drive device is activated, and the motor or cylinder pushes the two arc-shaped clamps closer together through the transmission mechanism. This may be accompanied by rotational or translational movements of the arc-shaped clamps to achieve the intersection of the extended portions, thereby reducing the clamping ring and forming a clamping through-hole that matches the external shape of the second quick-connect connector 8. Under the control of the control unit, the drive device can precisely control the movement trajectory and force of the arc-shaped clamps, ensuring the stability and reliability of the clamping process.

[0042] In this embodiment, the drip irrigation tape reel 3 includes a reel 13 and a drip irrigation tape 11. The reel 13 is equipped with a rotating shaft for easy rotation and tape unwinding. The drip irrigation tape 11 is wound around the reel 13. The first end of the drip irrigation tape 11 is equipped with a first quick connector 7, and the second end is equipped with a second quick connector 8 that can mate with the first quick connector 7. The two can mate with each other to achieve continuous laying of the drip irrigation tape. The first quick connector 7 is a male connector, and the second quick connector 8 is a female connector. The female connector is equipped with a funnel-shaped guide portion to facilitate the insertion of the male connector. The maximum outer diameter of the second quick connector 8 is larger than the outer diameter of the drip irrigation tape 11, so that the capturing device can clamp the second quick connector 8. The reel 13 is equipped with a quick-release latch for fixing the first quick connector 7, which facilitates the quick replacement and installation of the first quick connector 7. The roller 13 is provided with baffles 22 at both ends along the axial direction, and the baffles 22 are provided with a first positioning plane 23. When the drip irrigation tape roller 3 in standby state is placed on a horizontal surface through the first positioning plane 23, the first quick connector 7 fixed on the quick release buckle is vertically downward. The first positioning plane 23 can position the direction of the first quick connector 7 to ensure that it can be smoothly connected to the second quick connector 8 held by the capture device 9 below, which facilitates the continuation of the operation.

[0043] As an optional implementation, an easy-to-remove positioning buckle is connected between the first positioning plane 23 at the bottom of the baffles 22 at both ends of the drum 13. The easy-to-remove positioning buckle is used to limit the first quick connector 7 to be in the middle position of the axial direction of the drum 13. When the first quick connector 7 and the second quick connector 8 are connected vertically, the easy-to-remove positioning buckle automatically breaks under the action of external force during the connection, releasing the first quick connector 7.

[0044] As another optional implementation, based on the above scheme, a third positioning plane is also provided on the frame 1. The third positioning plane is connected to a transmission device and has an elastic device at its bottom. The elastic device can be a spring or other structure. After the roll 13 is placed on the drip irrigation tape roll holder 2, the first quick connector 7 faces downward. The roll 13 contacts the third positioning plane at the receiving structure 5 of the drip irrigation tape roll holder 2 to calibrate the angle. When the roll 13 passes through the vertical slide groove 6 of the drip irrigation tape roll holder 2, the third positioning plane moves downward with the downward pressure of the roll 13, causing the elastic device to be compressed. The third positioning plane can be removed by the transmission device after the roll 13 is placed and aligned to avoid obstructing the rotation of the roll 13. By setting the third positioning plane, it is ensured that the first quick connector 7 faces downward after the roll 13 is placed on the drip irrigation tape roll holder 2, thereby promoting the smooth alignment of the first quick connector 7 and the second quick connector 8. For example, please refer to Figure 6 and Figure 7A film-covering operation device includes the above-mentioned splicing device for drip irrigation tape, and also includes a support vehicle 19. The support vehicle 19 is provided with a storage position 20, and the bottom surface of the storage position 20 is provided with a second positioning plane adapted to the first positioning plane 23 for storing spare drip irrigation tape rolls 3. This avoids the first quick-connect joint 7 not being precisely vertically downward due to a certain angular deviation between the second positioning plane of the support vehicle and the plane of the frame, or slight movements that may occur during the movement of the roll by the robotic arm.

[0045] Please see Figure 5 (a)- Figure 5 (g) The working process of the drip irrigation tape splicing device of the present invention is as follows: When the drip irrigation tape is laid, the capturing device is in the released state; when the current drip irrigation tape is about to be used up, the capturing device prepares to position the end of the drip irrigation tape; after the current drip irrigation tape is used up, the capturing device positions the second quick connector of the end of the drip irrigation tape before the end of the drip irrigation tape reaches the guide wheel 12; after taking out the empty drip irrigation tape roll, a spare drip irrigation tape roll is put on to prepare for docking; the spare drip irrigation tape roll is inserted downward to complete the docking; the capturing device is released and the drip irrigation tape laying operation continues.

[0046] Please see Figure 6 and Figure 7 This invention also provides a film covering operation device, including the above-mentioned splicing device for drip irrigation tape, and a support vehicle 19. The support vehicle 19 is provided with a storage position 20 and a robotic arm 21. The bottom surface of the storage position 20 is provided with a second positioning plane adapted to the first positioning plane 23 for storing spare drip irrigation tape rolls 3. The support vehicle 19 can be positioned and run to a designated position, and the robotic arm 21 grabs the spare drip irrigation tape rolls 3 and installs the spare drip irrigation tape rolls 3 onto the drip irrigation tape roll bracket 2. The robotic arm's handling is a fixed action, ensuring that the angle of the drip irrigation tape rolls 3 remains unchanged during the process.

[0047] In summary, this invention, through the design of the quick-connect positioning component, achieves rapid and accurate splicing of drip irrigation tape, significantly improving operational efficiency. The device boasts a high degree of automation, reducing the need for manual operation and lowering labor costs. The capture device design ensures the stability and accuracy of the drip irrigation tape during splicing, improving operational quality and reducing problems such as leakage or breakage due to poor splicing. The device's rational structural design is suitable for different specifications and types of drip irrigation tape, enhancing its applicability. Furthermore, combined with components such as the support vehicle and robotic arm in the mulching operation device, it achieves automated storage, transportation, and installation of drip irrigation tape rolls, further improving operational efficiency and quality.
