Description

TECHNICAL FIELD

[0001] The utility model relates to agricultural irrigation auxiliary equipment technical field, concretely is a kind of micro-irrigation tape winding and unwinding device. BACKGROUND

[0002] Micro-irrigation tape is also quantitative water-saving equipment, and water is discharged through the holes on the surface. Generally, micro-irrigation tape is flat under no water pressure and can be wound to facilitate winding and unwinding. The common device used for winding and unwinding is a winding and unwinding device (winding machine) to facilitate winding and unwinding. However, the existing device has some problems. Micro-irrigation tape may be knotted during winding, which makes it impossible to wind the micro-irrigation tape. In addition, the micro-irrigation tape may be loose during transportation after being wound.

[0003] However, there is no device in the prior art that can solve all the above problems in the same device. For example, CN107915097B, a water pipe belt winding and unwinding device for water conservancy projects, points out that the cleaning mechanism and wiping mechanism can clean and wipe the water pipe belt before winding. The water pipe belt can be fixed by the clamping mechanism. The brake mechanism can fix the bottom plate, thereby achieving the effects of saving time and effort when winding the water pipe belt, easy fixation of the wound water pipe belt, and non-sliding of the entire device. However, if the water hose is knotted (the water hose is reversed during movement, forming a knot), it cannot be wound continuously, and manual intervention is required, which is inconvenient.

[0004] Therefore, in order to enable winding when the micro-irrigation tape is knotted, a micro-irrigation tape winding and unwinding device is proposed to solve the above problems. INVENTION CONTENTS

Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the utility model.

[0028] Embodiment

[0029] Please refer to Figures 1-10The utility model provides the following technical scheme: A kind of micro-spraying tape take-up and pay-off device, including take-up and pay-off box 1, the mounting protrusion 2 of counter shaft 14 and bearing seat 18 in take-up and pay-off box 1 is supported, take-up and pay-off box 1 inner wall is provided with ring mounting protrusion 33, bolt mounting is provided with triangular support rod 3 on the upper end of take-up and pay-off box 1, triangular support rod 3 left side is equipped with take-up and pay-off mechanism, the driving structure that can drive take-up and pay-off mechanism rotation and can drive micro-spraying tape take-up and pay-off position change is installed on the upper end of mounting protrusion 2, its driving structure is connected with take-up and pay-off mechanism by connecting structure, and driving structure is also installed with the protection structure of clamping anti-knot, protection structure includes the first mounting plate 12 installed on driving structure, the clamping wheel 32 of corresponding and end face contact is installed on the inner wall of first mounting plate 12, and first mounting plate 12 surface is installed with mounting block 13, second mounting plate 28 is installed on the upper surface of mounting block 13, upper protection plate 26 is installed in the inner wall of mounting block 13, lower protection plate 27 is installed below upper protection plate 26 in the inner wall of mounting block 13, the second mounting plate 28 upper surface is screw-mounted with bolt 29, the surface of bolt 29 is equipped with hand screw nut 30, the clamping wheel 31 of bolt 29 lower surface is connected, and the surface of clamping wheel 31 lower end and lower protection plate 27 is contacted.

[0030] In the embodiment, the specific working principle is as follows: in use, the user passes the micro-spraying tape between the upper protection plate 26 and the lower protection plate 27, then passes the micro-spraying tape through the two sets of clamping wheels 32, inserts one end of the micro-spraying tape into the take-up and pay-off mechanism, rotates the hand crank 16 to drive the driving structure to rotate, and then drives the take-up and pay-off mechanism to rotate, thereby realizing the take-up operation of the micro-spraying tape. At this time, if the micro-spraying tape reverses locally during the take-up movement, causing a knot to occur at a certain position, the upper protection plate 26 will contact the surface of the knotted micro-spraying tape through the action of the upper protection plate 26 and the lower protection plate 27, thereby stretching the knotted part through the tensioning force, and preventing the micro-spraying tape from being unable to be taken up due to the knot. Then the user rotates the hand screw nut 30 to move the bolt 29 downward, so that the clamping wheel 31 contacts the surface of the micro-spraying tape, thereby clamping the micro-spraying tape. It should be noted that the clamping wheel 31 is fixedly installed on the lower surface of the bolt 29. It should also be understood that, in the embodiment, the bearing seat 18 is connected to the ring mounting protrusion 33 through the connecting shaft, and the ring mounting protrusion 33 is internally provided with a ball bearing. When the micro-spraying tape is taken up, the water in the micro-spraying tape can be squeezed out through the extrusion between the two sets of clamping wheels 32, thereby reducing the overall weight of the device. Figure 10

[0031] According to the above, in order to prevent the upper protection plate 26 from being stuck when it contacts the knotted part of the micro-spraying tape, specific reference can be made to Figure 7 and Figure 9 ​It can be seen that the end of the upper protection plate 26 is polished with a circular arc, the upper protection plate 26 is symmetrically installed on the inner wall of the mounting block 13 along the vertical longitudinal section of the lower protection plate 27, and the length of the upper protection plate 26 is 1 / 2 of the length of the lower protection plate 27, and a gap is left between the upper protection plate 26 and the lower protection plate 27.

[0032] The driving structure can drive the micro-spraying belt to change the winding position, which can be specifically understood by referring to Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 8 It can be seen that the driving structure includes a rotating shaft 14 installed in the mounting protrusion 2 through a bearing seat and transversely penetrating the mounting protrusion 2, and the rotating shaft 14 extends to the outer end of the winding and unwinding box 1 through the ring-shaped protrusion 33, the outer end of the rotating shaft 14 is connected with a hand wheel 16, the upper end of the mounting protrusion 2 is installed with a mounting table 4, and the surface of the rotating shaft 14 installed in the mounting protrusion 2 is installed with a transmission helical gear 15, and the inner wall of the mounting protrusion 2 is further installed with a transmission gear 7, and the transmission gear 7 and the transmission helical gear 15 constitute gear transmission.

In use, the hand wheel 16 is rotated to drive the rotating shaft 14 to rotate, so that the transmission helical gear 15 drives the transmission gear 7 to rotate, and the transmission gear 7 and the transmission gear 8 rotate synchronously, so that the transmission gear 8 drives the transmission auxiliary gear 9 to rotate, and the two directions of rotation are opposite, so that the long strip gear 11 moves to both ends through the cooperation of the semicircular gear 10 and the long strip gear 11 installed on the upper ends of the two, and the mounting block 13 is moved through the sliding block 6 installed on the sliding rail 5, and the first mounting plate 12 is moved, so that the driving structure can drive the micro-spraying belt to change the winding position, so that the micro-spraying belt is more uniformly wound on the surface of the winding and unwinding wheel 24.

[0035] In order to enable the long strip gear 11 to move every time the transmission gear 8 and the transmission auxiliary gear 9 rotate one circle, which can be specifically understood by referring to Figure 4It can be seen that the two sets of half gear 10 are opposite, so when the transmission gear 8 and the transmission auxiliary gear 9 rotate, the half gear 10 will drive the long strip tooth 11 to move back and forth, thereby ensuring that the micro-spraying belt is wound more evenly on the surface of the winding and unwinding wheel 24.
