Description

Technical Field

[0001] This utility model relates to the field of drip irrigation technology for Chinese cabbage, and in particular to a drip irrigation and fertilization device for Chinese cabbage. Background Technology

[0002] Chinese cabbage is a leafy vegetable belonging to the Brassicaceae family. When irrigating and fertilizing, drip irrigation allows water and fertilizer to slowly and evenly penetrate into the soil, unlike flood irrigation which can easily cause soil compaction. This helps maintain the loose structure of the soil and provides a good soil environment for the growth of Chinese cabbage roots.

[0003] However, most drip irrigation and fertilization systems typically involve placing a water pipe in the soil to be irrigated, and then dripping liquid fertilizer through tiny holes in the pipe onto the cabbage plants. However, because the drip holes are fixed and cannot be rotated or adjusted, and because the cabbage seeds are often unevenly distributed due to human sowing (the seeds are not in a straight line), some seeds closer to the drip holes receive sufficient water and nutrients, germinating early and growing quickly. Other seeds farther from the drip holes receive insufficient water and nutrients, resulting in delayed germination and slower growth. This further exacerbates the growth differences between individual cabbages, leading to poorer overall uniformity. Furthermore, the limitations of the system require adjusting the spacing between rows of seeds when planting, increasing planting time and reducing efficiency.

[0004] Therefore, it is necessary to provide a new drip irrigation and fertilization device for cabbage to solve the above-mentioned technical problems. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model provides a drip irrigation and fertilization device for Chinese cabbage.

[0006] The drip irrigation and fertilization device for cabbage provided by this utility model includes two water pipes, with an inlet pipe fixedly connected to the top of the water pipes and connecting blocks symmetrically fixedly connected to both ends of the water pipes.

[0007] The fixing component is installed inside the connecting block;

[0008] Telescopic assembly, wherein telescopic assemblies are installed on the adjacent sides of the two water pipes;

[0009] The bottom of the water pipe is fixedly connected to multiple connecting pipes at equal intervals. The end of the connecting pipe away from the water pipe is externally threaded to an installation pipe. The installation pipe is rotatably connected to a rotating pipe. The bottom end of the rotating pipe is fixedly connected to a drip irrigation head.

[0010] Adjustment component: An adjustment component is installed on the outside of the mounting tube.

[0011] Preferably, the fixing component includes: a threaded rod, the threaded rod is internally threaded to the connecting block, a rotating disk is fixedly connected to the upper end of the threaded rod, a handle is fixedly connected to the side of the rotating disk away from the threaded rod, and a conical block is fixedly connected to the lower end of the threaded rod.

[0012] Preferably, the telescopic assembly includes: two mounting blocks, each of the two water pipes having a mounting block fixedly connected to an adjacent side, a connecting rod rotatably connected to the outside of the mounting blocks, a rotating column fixedly connected to the end of the connecting rod away from the mounting block, a mounting plate fixedly connected to an adjacent side of the two water pipes, a sliding hole provided inside the mounting plate, the rotating column being placed in the sliding hole and slidably connected thereto, and a rotating shaft installed at the axis of the two connecting rods, the two connecting rods being connected in an alternating manner via the rotating shaft.

[0013] Preferably, the adjusting component includes: a bolt, an internal threaded connection to one side of the mounting tube, a tightening block fixedly connected to one end of the bolt, and a limit plate fixedly connected to the outer ring wall of the bolt.

[0014] Preferably, the rotating tube is shaped like a transverse H.

[0015] Preferably, a friction block is provided on the end of the bolt away from the turning block, and the friction block is in contact with the outside of the rotating tube.

[0016] Preferably, the outer side of the limiting disk is slidably connected to the outer wall of the rotating tube.

[0017] Compared with related technologies, the cabbage drip irrigation and fertilization device provided by this utility model has the following beneficial effects: by rotating the drip head to a suitable position and then turning the turning block so that the bolt drives the friction block to squeeze and fix the rotating tube, the direction of the drip head can be adjusted. This can avoid the problem of uneven distribution of cabbage and uneven drip irrigation nutrients caused by human sowing, which leads to excessive differences in growth between individual cabbages.

[0018] The two water pipes are expanded outwards. During this process, the connecting rods connected to the two water pipes move under the action of the rotating shaft, causing the rotating column to slide inside the sliding hole of the mounting plate. The two connecting rods move up and down alternately under the action of the rotating shaft, which can adjust the distance between the two water pipes. The device can be flexibly adjusted according to the distance of each row of cabbage seeds, without having to adjust the distance between each row of seeds according to the limitations of the device, thereby improving planting efficiency.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] Please see Figures 1 to 3 A drip irrigation and fertilization device for cabbage includes: two parallel water pipes 1, which provide the main water supply channel for the drip irrigation and fertilization device; an inlet pipe 2 is fixedly connected to the top of the water pipe 1, which is the inlet for external water and fertilizer supply to enter the device; and connecting blocks 3 are symmetrically fixedly connected to both ends of the water pipe 1.

[0025] The fixing component is installed inside the connecting block 3. The fixing component includes: a threaded rod 4. The threaded rod 4 is threadedly connected inside the connecting block 3. This threaded connection can provide the threaded rod 4 with upward and downward movement when driven. The upper end of the threaded rod 4 is fixedly connected to a rotating disk 5 for connection. The side of the rotating disk 5 away from the threaded rod 4 is fixedly connected to a handle 6 to provide a force application surface for the operator. The lower end of the threaded rod 4 is fixedly connected to a conical block 7 to provide a fixing point for insertion into the ground.

[0026] The telescopic assembly is installed on the adjacent sides of the two water pipes 1. The telescopic assembly includes: two mounting blocks 8 providing a platform for installation; mounting blocks 8 are fixedly connected to the adjacent sides of the two water pipes 1; connecting rods 9 are rotatably connected to the outside of the mounting blocks 8 to provide spacing adjustment support; a rotating column 10 is fixedly connected to the end of the connecting rod 9 away from the mounting blocks 8 to provide a base point for rotation; mounting plates 11 are fixedly connected to the adjacent sides of the two water pipes 1; sliding holes 12 are opened inside the mounting plates 11; the rotating column 10 is placed in the sliding holes 12 and slidably connected to them, so that the rotating column 10 has enough space to move during the movement; a rotating shaft 13 is installed at the axis of the two connecting rods 9; the two connecting rods 9 are connected in an alternating manner through the rotating shaft 13; and multiple connecting pipes 14 are fixedly connected at equal intervals to the bottom of the water pipes 1.

[0027] Multiple connecting pipes 14 are fixedly connected at equal intervals to the bottom end of the water pipe 1. The end of the connecting pipe 14 away from the water pipe 1 is externally threaded with an installation pipe 15. The installation pipe 15 serves to connect the connecting pipe 14 and the rotating pipe 16. The rotating pipe 16 is rotatably connected inside the installation pipe 15. It not only has a rotating effect, but also serves to transport water and fertilizer. The rotating pipe 16 is shaped like a horizontal H. The H shape facilitates the rotation of the rotating pipe 16 inside the installation pipe 15. The bottom end of the rotating pipe 16 is fixedly connected with a drip irrigation head 17. The drip irrigation head 17 is the outlet for drip irrigation and fertilization, which drips water from the drip irrigation head 17 into the soil heavily loaded with cabbage seeds.

[0028] An adjustment assembly is installed on the outside of the mounting tube 15. The adjustment assembly includes a bolt 18, which is internally threaded onto one side of the mounting tube 15. A turning block 19 is fixedly connected to one end of the bolt 18. A friction block is provided on the end of the bolt 18 away from the turning block 19. The friction block contacts the outside of the rotating tube 16 to increase the friction force when the bolt 18 presses against the rotating tube 16. A limiting disc 20 is fixedly connected to the outer ring wall of the bolt 18. The outside of the limiting disc 20 is slidably connected to the outer wall of the rotating tube 16. This limiting disc 20 is to prevent the bolt from falling off during movement.

[0029] The working principle of the drip irrigation and fertilization device for cabbage provided by this utility model is as follows:

[0030] First, when adjusting the spacing between the two water pipes 1, expand them outwards. During this process, the connecting rods 9 connected to the two water pipes 1 move under the action of the rotating shaft 13, causing the rotating column 10 to slide inside the sliding hole 12 of the mounting plate 11. The two connecting rods 9 move up and down alternately under the action of the rotating shaft 13, thus completing the spacing adjustment of the two water pipes 1. After the adjustment is completed, operate the handle 6. The movement of the handle 6 drives the rotating disk 5 to rotate, which in turn drives the threaded rod 4, causing the threaded rod 4 to move downwards so that the conical block 7 contacts the ground. Through the friction between the conical block 7 and the ground, the entire device is fixed, ensuring the stability of the device during operation. This allows for flexible adjustment of the device according to the distance of each row of cabbage seeds, improving planting efficiency. Furthermore, this operation method allows the conical block to descend more smoothly, ensuring it enters the ground vertically and improving the stability of the fixation. This eliminates the need for the operator to directly contact the conical block, avoiding the risk of slipping and twisting during footwork.

[0031] When the direction of the drip irrigation head 17 needs to be adjusted, first turn the turning block 19. The rotation of the turning block 19 causes the bolt 18 to rotate, so that the friction block is no longer in contact with the rotating tube 16, thus eliminating the squeezing force and releasing the lock on the rotating tube 16. At this time, rotate the drip irrigation head 17, which drives the rotating tube 16 to rotate, adjusting it to the required position. Then turn the turning block 19 in the opposite direction. The turning block 19 drives the bolt 18 to rotate, so that the friction block at one end of the bolt 18 is brought close to the rotating tube 16, squeezing the rotating tube 16, thereby completing the fixation of the drip irrigation head 17 after adjustment. This avoids problems such as uneven distribution of cabbage and cabbage seeds not being in a straight line, resulting in uneven drip irrigation nutrients and excessive differences in individual cabbage growth.
