Detailed Implementation
[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.
[0018] Specific implementation method one: Combining Figure 1-16 As shown, a drip irrigation tape laying device includes: a first base 1 and a suspension frame 2; a second base 101 is arranged opposite to the first base 1, and both are respectively arranged on a vehicle for synchronous forward movement; both the first base 1 and the second base 101 are provided with a winding device 102, and steel wire ropes are wound on the winding device 102, forming a steel cable track through the connection of the ends of the steel wire ropes; the first base 1 is provided with a discharge part 3 for the extension of the drip irrigation tape, and the second base 101 is provided with a stabilizing part 4 for fixing the end of the drip irrigation tape; the upper part of the suspension frame 2 is fixedly connected to two steel cables, and the lower part is provided with a liftable pressure relief device 5, and pressure nails 6 are arranged inside the pressure relief device 5. By lifting the pressure relief device 5, the pressure nails 6 can be close to the ground surface when fixing the pressure nails, ensuring the nailing effect, and can deal with the sagging problem caused by the steel wire rope when the span is too long.
[0019] Preferred embodiments, in combination Figure 4-6As shown, the discharge section 3 includes a first support 301 and a second support 302. The first support 301 is fixed to the middle of the first base 1, and a trough is provided in the middle for placing the drip irrigation tape roll. The support shafts at both ends of the roll are placed in the trough to form support and can rotate under pulling. The second support 302 is fixed to the outside of the first base 1 and close to the edge of the first base 1. Two sets of guide wheels 303 are distributed on the second support 302. The drip irrigation tape enters the discharge channel in the middle of the second support 302 through the two sets of guide wheels 303. In section 304, an electric motor is installed at the outer guide wheel 303 to assist in driving the drip irrigation tape to move outward. A cutting component 305 is provided on the second bracket 302 directly above the discharge channel 304. The cutting component 305 consists of an electric push rod and a cutter on the electric push rod. It can cut the drip irrigation tape after it has been pulled to a specified length. In order to achieve the sealing treatment after the drip irrigation tape is cut, the cutter can be replaced with a heat sealing blade, which can seal the end of the drip irrigation tape on the one hand and cut it on the other.
[0020] Preferred embodiments, in combination Figure 4-6 As shown, the second support 302 is equipped with a rotatable flipping frame 306. The flipping frame 306 is connected to the second support 302 by a rotating shaft, and a gear is installed at the rotating shaft connection position. A control motor is installed above the second support 302. The control motor is connected to the flipping frame 306 through the gear. The flipping frame 306 can be rotated by driving it. The flipping frame 306 is equipped with a length-adjustable pressing rod 307. The end of the pressing rod 307 has a semi-circular pressing block. After rotation and adjustment, the pressing block can contact the drip irrigation tape and press it to a position close to the ground to avoid the drip irrigation tape being discharged at an angle and not being long enough after cutting. At the same time, the pressing block can also be used to position this end of the drip irrigation tape during subsequent nailing operations to prevent skewing, displacement, etc., and improve the nailing quality.
[0021] Preferred embodiments, in combination Figure 8-10 As shown, the suspension frame 2 is provided with a first screw 201, and a control motor is installed at the top of the first screw 201. Above the pressure relief device 5, there are multiple guide rods 202 that pass through the suspension frame 2 and form a sliding connection, preferably four. The middle part of the pressure relief device 5 is provided with a threaded seat 203 that is connected to the first screw 201. The threaded seat 203 and the first screw 201 form a threaded connection. By controlling the motor to drive the first screw 201 to rotate, the pressure relief device 5 can be driven to move up and down, thereby meeting the needs of nail pressing operation and height adjustment.
[0022] Preferred embodiments, in combination Figure 9As shown, the suspension bracket 2 consists of an upper fixing plate and a lower housing. The fixing plate has a gap in the middle to facilitate the suspension of the wire rope. Simultaneously, there are semi-circular holes on both sides with the same diameter as the wire rope, and screw-connected pressure plates are located at the semi-circular holes. These pressure plates also have semi-circular holes for fixing the wire rope. The fixing plate and housing can be directly welded together. To increase the height adjustment of the housing, a guide rod 202 structure can be installed on the top of the housing, which, together with the first screw 201 structure, is threadedly connected to the fixing plate, allowing for active height adjustment of the housing. Adjustment: After tensioning, the wire rope is bent near the middle due to its own span, causing the pressure relief device 5 to be in a certain tilted state. When the tilt angle is small, it will not affect the fixation of the drip irrigation tape. The pressure nail 6 tilts into the soil to meet the fixation requirements. In order to improve the possibility of vertical insertion into the soil, the fixing plate is connected to the top of the box with a rotating shaft and maintains a vertical state under its own weight. At the same time, the internal structural design of the pressure relief device 5 is reasonably arranged to improve the balance. Limiting devices should be set at the rotating shaft connection between the box and the fixing plate, such as the box being able to be adjusted between +15° and -15°.
[0023] Preferred embodiments, in combination Figure 2 and Figure 3 As shown, the stabilizing part 4 includes a base 401 and an upper crossbeam 402. The base 401 is fixed below the second base 101, and a plurality of suction heads 403 are arranged in sequence in the middle of the base 401. The suction heads 403 are connected to the negative pressure device. After the pressure relief device 5 pulls the drip irrigation tape in, the negative pressure suction of the suction heads is used to adsorb and fix the drip irrigation tape that has fallen. The upper crossbeam 402 is installed in the middle of the second base 101 and is located in the area directly above the base 401. The upper crossbeam 402 is equipped with a pressure-stabilizing hydraulic cylinder 404. The pressure-stabilizing hydraulic cylinder 404 is used to press and fix the drip irrigation tape, which can keep the end stable during subsequent nailing operations.
[0024] Preferred embodiments, in combination Figure 8-14As shown, the pressure relief device 5 includes a support frame 7, a displacement frame 8, and a thrust member 9. The bottom of the support frame 7 is symmetrically provided with guide channels 701, and a travel channel 702 for the displacement frame 8 to pass through is formed between the two guide channels 701. Above the travel channel 702, a first drive member 703 and a second drive member 704 are sequentially arranged on the support frame 7. The second drive member 704 contacts the pressure pin 6 inside the guide channel 701 and can push the pressure pin 6 to move along the guide channel 701. A vertical channel 7 is provided at the outlet end of the guide channel 701. 05. A thrust member 9 is installed on the support frame 7 directly above the vertical channel 705, and the end of the thrust member 9 is provided with a push plate 901 that is slidably connected to the vertical channel 705; the displacement frame 8 is connected to the first drive member 703, and the displacement frame 8 is provided with a claw arm 801. The mechanical claw on the claw arm 801 can grasp and fix the drip irrigation tape, and driven by the first drive member 703, the drip irrigation tape can be pulled into the two guide channels 701. Then, under the overall displacement of the pressure relief device 5, the drip irrigation tape of the first base 1 is pulled to The second base 101 is used to fix the pulling end, and the stabilizing part 4 fixes it. After fixing, the winding device 102 drives the pressure relief device 5 to reset. During the reset process, the thrust member 9 pushes the pressure nail 6 to move along the vertical channel 705 for each displacement distance, realizing the nailing operation. After reaching the designated position, the second driving member 704 pushes the next pressure nail 6 into the vertical channel 705. The pressure nail 6 elastically resets itself the instant it leaves the vertical channel 705, realizing the clamping and installation of the drip irrigation tape on both sides. The overall structure is stable and reliable, and... During the placement of the pressure nails 6, the support frame 7 can actively make fine-tuning adjustments to its height, avoiding interference with the pressure nails 6 during resetting and movement. During the pressure nailing process, the claw arm 801 can be positioned in the middle area of the guide channel 701. In order to further improve the stability of the drip irrigation tape between the two guide channels 701, an adsorption device similar to the adsorption head 403 can be added below the claw arm 801 to assist in fixing the drip irrigation tape. At the same time, the suction force is controlled, such as adsorption during the pressure nailing operation and release during displacement, to avoid motion interference.
[0025] Preferred embodiments, in combination Figure 13As shown, the bottom of the guide channel 701 is provided with a first through groove 706, which provides displacement space for the lower half 602. The top of the guide channel 701 is provided with a second through groove 707. The inner wall of the guide channel 701 is provided with a positioning rib 708, which can assist the positioning and sliding of the pressure nail 6 and improve the positioning reliability. The middle of the outer wall of the guide channel 701 is provided with a rectangular space 709. The rectangular spaces 709 of the two guide channels 701 form an intermediate channel 10 for the support and passage of the drip irrigation tape. This solves both the storage position of the pressure nail 6 and the installation connection between the pressure nail 6 and the drip irrigation tape. It also provides space for the drip irrigation tape to enter and move, and will not interfere with the pressure nail 6 and the claw arm 801. The overall structure design is reasonable and compact.
[0026] Preferred embodiments, in combination Figure 12 As shown, the second driving component 704 includes a second screw 7041 and an intermediate plate 7042. The two ends of the second screw 7041 are connected to the support frame 7 by rotating shafts, and a control motor is installed at one end. The upper part of the intermediate plate 7042 is threadedly connected to the second screw 7041, and the lower part is slidably connected to the second through groove 707. A flat pusher 7043 is provided in the guide channel 701. The flat pusher 7043 has an overall C-shaped plate structure, similar to the internal structure of the guide channel 701, which can increase the contact area with the pressure nail 6 and improve the force stability of the pressure nail 6 when pushing. The first driving component 703 also has part of the structure of the second screw 7041 and forms a threaded connection with the displacement frame 8. Driven by the control motor, it can drive the displacement frame 8 to achieve displacement adjustment.
[0027] Preferred embodiments, in combination Figure 11 and Figure 12 As shown, the stroke length of the intermediate plate 7042 is greater than the length of the guide channel 701, so that after the intermediate plate 7042 is moved to the tail end, space can be reserved for the insertion of the pressure nail 6 from the end of the guide channel 701.
[0028] Preferred embodiments, in combination Figure 14 and Figure 15As shown, the pressure nail 6 includes an upper half 601 and a lower half 602. The upper half 601 is made entirely of plastic and has a C-shaped structure when open. A positioning groove 603 is provided on the inner wall of the upper half 601, which connects with the positioning rib 708 for positioning. The thickness of the upper half 601 in the top two-thirds section is less than that in the lower section, so that when the pressure nail 6 is fully pushed into the vertical channel 705, the upper section of the upper half 601 can elastically return to its original position, thus completing the positioning of the drip irrigation tape. The clamping mechanism ensures that the upper half 601 will not interfere with the elastic reset of the lower half 602 due to contact with the inner wall of the vertical channel 705. One end of the lower half 602 is fixedly connected to the upper half 601. The lower half 602 is made of metal and is cylindrical in shape with a pointed bottom for easy insertion into the soil. The upper half 601 is made of modified polypropylene with added additives such as hindered amine light stabilizers, ultraviolet absorbers, and antioxidants to meet the requirements for outdoor use. The lower half 602 is made of galvanized low-carbon steel wire, which is strong and low in cost.
[0029] Preferred embodiments, in combination Figure 16 As shown, the flipping frame 306 has two rectangular plate structures, and multiple positioning holes are provided at equal intervals along the length of the plate. The pressing rod 307 has a sleeve structure that connects to the plate, and a docking hole is provided. By cooperating with the positioning holes at different positions through the docking hole, the position of the pressing rod 307 can be adjusted, which enhances practicality. The docking hole and the positioning hole are fixed by bolts, which is simple and reliable.
[0030] Preferred embodiments, in combination Figure 7 As shown, the ends of the wire ropes on the first base 1 and the second base 101 are respectively provided with a left sleeve and a right insert shaft, and both are provided with locking holes. After insertion, bolts are inserted into the locking holes to fix them, which can realize the connection between the two wire ropes, and the winding device 102 is used to tension the wire ropes.
[0031] Preferred embodiments, in combination Figure 2 and Figure 6 As shown, the tensioning mechanism 11 includes an active hydraulic cylinder and two roller shafts. Rollers are arranged on the roller shafts, and rollers are also installed at the ends of the active hydraulic cylinder. The wire rope extending from the winding device passes through each roller in sequence to achieve guidance and support. Furthermore, the active hydraulic cylinder can be used to push and assist in tensioning the wire rope.
[0032] Preferred embodiments, in combination Figure 6As shown, the winding device 102 includes a drive shaft and a worm gear. The two ends of the drive shaft are connected to the base by rotating shafts, and wire rope coils are provided at both ends. A worm wheel is provided in the middle of the drive shaft. The two ends of the worm gear are connected to the bottom of the base by rotating shafts, and a power motor is installed at one end. The worm gear is driven to rotate by the power motor, which can realize the winding and unwinding of the wire rope.
[0033] A method for laying drip irrigation tape using a drip irrigation tape laying device includes the following steps: S1. Install the first base 1 and the second base 101 onto the vehicle respectively, and complete the erection of the steel cable track, the installation of the pressure nails, and the displacement of the suspension frame to the initial position in sequence. S2. The claw arm 801 on the pressure relief device 5 grabs the end of the drip irrigation tape, and the winding device drives the pressure relief device to move towards the second platform to complete the laying of the drip irrigation tape. S3. When the end of the drip irrigation tape is pulled to the stabilizing part 4 of the second base 101, the claw arm 801 releases the drip irrigation tape, and the stabilizing part 4 adsorbs and presses the end of the drip irrigation tape to fix it. S4. Start the winding device 102 to run in reverse, so that the suspension frame 2 and the pressure relief device 5 are reset along the steel cable to the first base 1. During the reset process, the pressure relief device 5 stops periodically and pushes the pressure nail 6 in the guide channel 701 into the vertical channel 705, so that the upper half 601 of the pressure nail 6 clamps the two sides of the drip irrigation tape, and the lower half 602 of the pressure nail 6 is pressed into the soil by the thrust member 9 to complete the fixing of the drip irrigation tape. S5. When the pressure relief device 5 is reset to the first base 1, the cutting part 305 of the discharge section 3 is activated to cut the drip irrigation tape. Then, the vehicle drives the first base 1 and the second base 101 forward to the next laying area. The above steps are repeated to complete the continuous laying operation.
[0034] Overall working principle: The first base 1 and the second base 101 are respectively installed on the corresponding vehicles, and the bottom surfaces of the two are as close to the ground as possible. The steel wire rope between the winding devices 102 is connected and tensioned to form a steel cable track. Then, the suspension frame 2 is installed and fixed to the steel wire rope. A certain amount of pressure nails 6 are pre-installed in the guide channel 701. At the same time, the pressure discharge device 5 is adjusted to the first base 1. The drip irrigation tape roll is put into the first bracket 301 and the drip irrigation tape is manually pulled through the two sets of guide wheels 303 and into the discharge channel 304. The preparation work is completed. The claw arm 801 grips the end of the drip irrigation tape in the discharge channel 304, and with the partial rotation of the guide wheel 303, pulls the drip irrigation tape to the middle area of the guide channel 701. Then, the two winding devices 102 operate separately. The one on the second platform 101 is winding, while the one on the first platform 1 is releasing synchronously, pulling the pressure relief device 5 to move towards the second platform 101. After moving a certain distance, the flipping frame 306 rotates, pressing the drip irrigation tape in the discharge direction to the area close to the ground, so as to make it easier to reserve the length for later use. After being pulled to the stabilizing part, the claw arm 801 releases the drip irrigation tape, and the drip irrigation tape falls horizontally onto the stabilizing part 4, where the stabilizing part 4 fixes the drip irrigation tape. Two sets of winding devices 102 work in opposite directions, driving the pressure relief device 5 to reset. During the reset process, after running to the designated position, the winding device 102 stops working and pushes a set of pressure nails 6 into the vertical channel 705 to achieve installation connection with both sides of the drip irrigation tape. Then, the thrusting member 9 pushes it out and presses it into the soil. During this process, observe the position relative to the ground and adjust the height of the support frame 7. When it resets to the first base 1, the cutting member 305 cuts the drip irrigation tape, completing one arrangement. The vehicle moves the first seat 1 and the second seat 101 forward to the designated area and actively adjusts the tension of the wire rope to repeat the above operation process.
[0035] This device, as an agricultural machinery component, works in conjunction with small agricultural vehicles to solve the drawbacks of traditional manual pulling and large-scale mechanical tape laying. It can be adjusted in a timely manner according to the span of farmland, has excellent versatility, and can be widely used for tape laying and irrigation operations during the planting stage of farmland. Moreover, after the tape is laid, the resetting process completes the fixation of the drip irrigation tape with the pressure nails 6. The overall production process of the device is reasonable and reliable. The pressure nails 6 can also be taken away during the drip irrigation tape recycling process to avoid soil pollution. At the same time, the pressure nails 6 can be removed and reused to reduce laying costs. It is suitable for the actual situation of drip irrigation in existing land in the north and improves laying efficiency. This device, when used with agricultural vehicles, involves installing fertilizer storage boxes and other components on the suspension frame 2. By using steel wire ropes to pull the suspension frame 2 back and forth, it can also be used to carry out fertilization operations after crop planting, thus serving as an agricultural fertilization component.
