Description

Technical Field

[0001] The invention relates to the technical field of drip irrigation belt punching, in particular to a drip irrigation belt punching method. Background Art

[0002] Drip tape is a device used for local irrigation, which irrigates crops by delivering water to their roots through holes or drippers on capillary tubes;

[0003] The water outlet of the drip irrigation tape is generally small and difficult to accurately locate and punch holes, especially for the patch-type drip irrigation tape, whose water outlet is designed on the dripper, and the dripper is bonded to the inner wall of the water hose at intervals. If the hole spacing is not well controlled, it is easy to hit the water hose, causing the drip irrigation tape to be scrapped. As the strip-type drip irrigation tape has a thinner strip, it is easy to punch through both the upper and lower layers of the water hose if the hole depth is not well controlled, resulting in waste. The present invention provides a method for accurate hole punching. It can not only accurately control the position, hole spacing and hole depth of the hole, but also is simple to operate.

[0009] Preferably, the connecting rod mechanism is fixedly connected to the inside of the frame, and the connecting rod cylinder is fixedly connected to the inside of the frame, so that the connecting mechanism and the second multi-wheel pulley can be driven to move under the action of the connecting rod cylinder.

[0010] Preferably, the synchronous belt and the transmission multi-belt are made of wear-resistant material and anti-slip material, which can improve the service life and effect through the wear-resistant and anti-slip materials.

By setting up two groups, the stability of supporting the frame can be ensured.

[0014] Compared with the prior art, the present invention provides a method for drilling holes in a drip irrigation belt, which has the following beneficial effects:

[0015] 1. The drip irrigation belt punching method, through the knife head mechanism, when the drip irrigation belt body is punched, it rotates at high speed with the knife seat under the drive of the X-axis adjustment servo motor and the Y-axis adjustment servo motor. When the tip of the knife rotates to the support wheel position, a small hole is left on the drip irrigation belt, and this hole is the outlet of the drip irrigation belt. The punching knife punches a hole every time it rotates one circle. The time used for each rotation corresponds to the distance the drip irrigation belt travels, which is the spacing of the outlets. This solves the problem that the outlets of the existing drip irrigation belts are generally small and difficult to accurately locate and punch, especially the outlet design of the patch-type drip irrigation belt is The dripper is bonded to the inner wall of the water hose at intervals. If the drilling spacing is not well controlled, it is easy to hit the water hose, causing the drip irrigation belt to be scrapped. The operator manually adjusts the manual displacement table to change the distance between the knife tip and the support wheel to control the drilling depth. If you want to adjust the spacing of the water outlets, you only need to change the speed of the servo motor, thereby improving the drilling quality and drilling spacing of the device, and the position of the frame and the knife seat can be conveniently moved under the action of the universal wheel, so that drilling work can be carried out in different working areas, improving the convenience and applicability of operation.

[0016] 2. The method for punching holes in the drip irrigation tape has a screw assembly. When the Y-axis adjustment servo motor drives the screw assembly to move back and forth along the Y-axis direction, the tool holder, the tool holder and the punching knife also move back and forth along the Y-axis direction; thereby, the Y-axis direction of the punching position can be accurately positioned. When the equipment is abnormal or shut down, the piston rod of the X-axis cylinder is pushed out. Since the piston rod of the X-axis cylinder is connected to the plate that fixes the screw assembly, the punching knife can be kept away from the support wheel. In this way, a certain space is formed between the punching knife and the support wheel, which is convenient for manual threading of the drip irrigation tape or replacement of the punching knife. At the same time, the X-axis adjustment servo The motor can adjust the punching position in the X-axis direction, and the punching position in the Y-axis direction can be adjusted by adjusting the servo motor through the Y-axis. The connecting rod cylinder is connected to the connecting rod mechanism. When the connecting rod cylinder piston rod retracts, the second multi-wedge pulley will rotate a certain angle with the fixed end of the connecting rod mechanism as the center. At this time, the position of the second multi-wedge pulley changes, and the multi-wedge belt is in a loose state, so it is very easy to thread the belt manually. After the belt is threaded, the connecting rod cylinder piston rod extends out, and the second multi-wedge pulley returns to the initial position. The multi-wedge belt is tensioned at the same time and starts to pull, so that the operator can thread the belt flexibly.

[0017] 3. The drip irrigation tape drilling method, through the setting of the support mechanism, when the position of the frame and the knife seat is moved to the working area under the action of the universal wheel, the first cylinder drives the mounting seat, the connecting rod and the support seat to move, so that the support seat contacts the ground, and the universal wheel can be lifted up to keep the universal wheel away from the ground, so as to ensure the stability of the frame during use and improve the safety of the drilling work. The support seat is threadedly connected to the inside of the connecting rod by a limit pin for limiting. When the support seat is worn and needs to be replaced, it only needs to remove the limit pin. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Embodiment 3

[0036] See also Figure 1-7 , and on the basis of Example 1 and Example 2, it is further obtained that the supporting mechanism 5 includes a fixing block 51, the fixing block 51 is fixed to the right side of the frame 1, the top of the fixing block 51 is fixedly connected to the first cylinder 52, the bottom of the first cylinder 52 is fixedly connected to the mounting seat 53, a connecting rod 55 is inserted inside the mounting seat 53, and the bottom of the connecting rod 55 is fixedly connected to the supporting seat 56, the connecting rod 55 is internally threadedly connected to a limiting pin 54, the limiting pin 54 runs through the inside of the mounting seat 53, the mounting seat 53 and the connecting rod 55 are respectively provided with fixing grooves, and the two fixing grooves correspond to each other, the limiting pin 54 is threadedly connected in the limiting groove, so as to ensure the stability of the connecting rod 55 under the action of the limiting pin 54, thereby ensuring the stability of the supporting seat 56, and at the same time facilitating the replacement of the supporting seat 56.

[0037] There are two groups of fixed blocks 51, first cylinders 52, mounting seats 53, limit pins 54, connecting rods 55 and supporting seats 56. The two groups of fixed blocks 51, first cylinders 52, mounting seats 53, limit pins 54, connecting rods 55 and supporting seats 56 are symmetrically distributed on the left and right sides of the frame 1. By setting up two groups, the stability of supporting the frame 1 can be guaranteed.

[0038] In actual operation, when the device is used, first, according to the working area where holes are to be punched, the frame 1 and the knife seat 61 are moved to the working area under the action of the universal wheel 4. When the movement is completed, the first cylinder 52 drives the mounting seat 53, the connecting rod 55 and the supporting seat 56 to move, so that the supporting seat 56 is in contact with the ground, and the universal wheel 4 can be lifted up to keep the universal wheel 4 away from the ground, so as to ensure the stability of the frame 1 during use and improve the safety of the punching work. The supporting seat 56 is threadedly connected to the inside of the connecting rod 55 by the limiting pin 54 for limiting. When the supporting seat 56 is worn and needs to be replaced, only the limiting pin 54 needs to be removed;

[0039] When working, the punching knife is fixed on the knife holder 61, and rotates at high speed with the knife holder 61 under the drive of the servo motor. When the tip of the knife rotates to the position of the support wheel 92, a small hole is left on the drip irrigation belt, which is the water outlet of the drip irrigation belt. The punching knife punches a hole every time it rotates one circle. The time used for each rotation corresponds to the distance the drip irrigation belt travels, which is the spacing of the water outlets. If you want to adjust the spacing of the water outlets, you only need to change the speed of the X-axis adjustment servo motor 63 and the Y-axis servo motor. In addition, in order to improve the quality and precision of punching, the screw assembly 67 is connected to the X-axis adjustment servo motor 63, the tool holder 62 is connected to the screw assembly 67, and the knife holder 61 is connected to the tool holder 62. The punching knife is fixed on the knife holder 61. Therefore, when the Y-axis servo motor drives the nut in the screw assembly 67 to move back and forth along the Y-axis direction, the tool holder 62, the knife holder 61 and the punching knife also move back and forth along the Y-axis direction, so that the Y-axis direction of the punching position can be accurately located.

[0040] When the equipment is abnormal or shut down, the piston rod of the X-axis cylinder 64 is pushed out. Since the piston rod of the X-axis cylinder 64 is connected to the plate of the fixed screw assembly 67, the punching knife can be kept away from the support wheel 92, so that a certain space is formed between the punching knife and the support wheel 92, which is convenient for manually wearing the drip irrigation tape or replacing the punching knife. In addition, since the cylinder stroke is a fixed value, it cannot be fine-tuned. When the punching knife is worn or the thickness of the drip irrigation tape changes, it is easy to cause the drip irrigation tape to be punched shallowly or penetrated. A manual displacement table 691 is provided. As shown in the above figure, the adjustment direction of the manual displacement table 691 is along the X-axis direction. The manual displacement table 691 stroke can be adjusted manually with the micrometer 65 to accurately control the depth of the punching. The outlet position of the drip irrigation tape can be adjusted in both the X-axis direction and the Y-axis direction, so that the punching position can be accurately located. In addition, the servo motor can accurately control the rotation speed of the punching knife, so that the spacing of the outlets is also guaranteed. Therefore, it has more advantages than other mechanisms in controlling the punching position, punching depth and punching spacing of the drip irrigation tape.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
