Description

Technical Field

[0001] The utility model relates to the field of spraying and applying pesticides to crops, in particular to a pipe pulling auxiliary device used for retracting and releasing a water pipe. Background Art

[0002] In the process of tobacco field planting, fertilizing and spraying are mostly done manually by carrying medicine boxes on their backs. Although this method is backward, it is relatively common and has certain reasons for its existence. In addition, some equipment uses a longer nozzle to connect to the sprayer, and people use the nozzle to perform a larger range of spraying operations. Compared with the traditional manual weight-bearing spraying method, it is a significant improvement. However, the longer nozzle cannot be fixed during operation, and the tobacco plants are easily damaged during the dragging process. In addition, the pipe collection process is also time-consuming and labor-intensive, such as the generation of messy knots. The subsequent disassembly and straightening process is also very cumbersome, requiring at least two people to work together, and the labor cost is also high. Pipe pulling auxiliary tools are required, and the existing pipe pulling auxiliary tools are mostly integrated structures. When not in use, they are inconvenient to carry and occupy a large space. At the same time, most of them use support wheels on one side and support rods on the other side to pull the pipe. When the support rods are supported during the pipe pulling process, the pipe pulling is not smooth.

[0003] Therefore, those skilled in the art have provided a pipe pulling auxiliary device for retracting and releasing a water pipe to solve the problems raised in the above background technology. Utility Model Content

DETAILED DESCRIPTION

[0017] See also Figures 1 to 5, a pipe pulling auxiliary device for retracting and releasing a water pipe comprises a support rod 1, a rotating ring 103 is fixedly connected to the top of the support rod 1, a U-shaped support member 3 is rotatably connected inside the rotating ring 103, and rotating support blocks 4 are arranged on both sides above the U-shaped support member 3; a guide support rubber wheel 5 is arranged on the periphery of the U-shaped support member 3 above the rotating support block 4, and bearings 501 are installed at the top and bottom of the inner wall of the guide support rubber wheel 5 in an interference fit manner, and the two guide support rubber wheels 5 are rotatably connected to the U-shaped support member 3 through the bearings 501, and a threaded portion 102 is arranged on the periphery of the support rod 1 below the rotating ring 103, and a rotating support nut 9 is threadedly connected to the periphery of the threaded portion 102, and a top block 10 is movably arranged on the periphery of the support rod 1 above the rotating support nut 9, and the top block 10 comprises an avoidance square hole 1003 opened in the middle of the top block 10, a top tightening arc groove 1001 opened above the top block 10, and a non-slip leather pad 1002 glued to the surface of the nail tightening arc groove 1001.

[0018] By adopting the above technical solution, the support rod 1 is connected to the U-shaped support member 3 by setting a rotating ring 103. When not in use, the top block 10 can be separated from the U-shaped support member 3 by rotating the rotating support nut 9. The rotating ring 103 and the support rod 1 can be rotated along the U-shaped support member 3 to fold the device, which is convenient for carrying in a storage box. In addition, by setting two guide support rubber wheels 5 for assisting in pulling the pipe, it is convenient to pull the pipe on either side, thereby solving the problem that the pipe cannot be pulled smoothly when the support rod 1 is used to support the pipe when one side uses a support wheel and the other side uses the support rod 1.

[0019] Among them, after the connecting screw sleeve 7 and the stud 302 are threadedly connected, the connecting screw sleeve 7 is axially pressed to be fixed after being screwed together with the locking nut 8, which can facilitate the rotation and disassembly of the handle and the connecting screw sleeve 7 assembly, and then facilitate the disassembly and installation of the rotating support rubber wheel, and can facilitate the replacement operation of the rotating support rubber wheel assembly, which is extremely practical.

[0020] In this embodiment, an L-shaped earth-entering reinforcement fork 2 is welded on the side wall of the support rod 1 below the rotating support block 4. The bottom ends of the L-shaped earth-entering reinforcement fork 2 and the support rod 1 are both earth-entering spikes 101. The earth-entering spikes 101 can facilitate the fixation of the device into the ground, and can be fixed by inserting the L-shaped earth-entering reinforcement fork 2 and the support rod 1 into the ground.

[0021] When in use, the support rod 1 is connected to the U-shaped support 3 by setting a rotating ring 103. First, the support rod 1 is turned open, and the top block 10 is nailed to the U-shaped support 3 by rotating the supporting nut 9 to achieve its unfolding and fixing. Then the device is inserted into the soil to achieve fixation. The water pipe is passed between the two rotating support rubber wheels, and then one end of the water pipe is pulled to drag the water pipe into the tobacco field. This can ensure that the water pipe is in an untangled state, and the water pipe is kept close to the rotating support rubber wheel. With the advantage of the free and easy rotation of the rotating support rubber wheel, the water pipe can be easily dragged into the tobacco field, thereby preventing tangling and messiness, thereby saving a lot of manual sorting time.
