Description

A quantitative watering device for tomato seedlings

Technical Field

The utility model relates to the technical field of tomato planting, in particular to a quantitative watering device for tomato seedlings.

Background Art

Tomato, also known as tomato, is an annual herbaceous plant of the Solanaceae family Solanum, with a plant height of up to 2 meters. The genetically modified tomatoes are bright red in color, the fruits are hard and not easy to crack. The stems of tomatoes are easy to fall over; the leaves are pinnate, the base is wedge-shaped, relatively oblique, and have irregular serrations; the corolla is radial, yellow, and the lobes are narrow and oblong; the berries are oblate or nearly spherical, fleshy and juicy, orange or bright red, with a smooth surface, and the flowering and fruiting period is summer and autumn; the seeds are yellow and covered with soft hairs;

During the planting process of tomatoes, they need to be continuously watered and irrigated by humans to prevent the tomato seedlings from drying up. Now, automated watering equipment is used to irrigate the tomato seedlings.

For example, the public document with application number 202223573925.4 discloses a quantitative irrigation device for sea buckthorn planting. The utility model has the advantages of blocking impurities in the water and being able to adjust the water delivery flow rate, which makes it inconvenient to control the irrigation amount of the water source. The water outlet pipe of the irrigation device can adjust its rotation angle, which solves the problem that impurities in the water cannot be blocked during the transportation process, impurities entering the irrigation device easily cause blade blockage, the water delivery flow rate cannot be adjusted, which makes it inconvenient to control the irrigation amount of the water source, the water outlet pipe of the irrigation device cannot adjust its rotation angle, and it is inconvenient to connect with the external water source delivery pipeline. The device also belongs to the irrigation device for planting crops, but when watering, the water pipe nozzle or the water pipe dripper can only irrigate the vegetation seedlings at a fixed angle position on one side. The irrigation range is small, and it is difficult to flexibly adjust. It is also difficult to flexibly adapt to the irrigation of seedlings of different growth stages and heights. If the vegetation garden is large, a large number of irrigation devices need to be installed, which will in turn invest a lot of capital costs, which is not conducive to use.

Therefore, in view of this, the existing structural deficiencies are studied and improved, and a quantitative irrigation device for tomato seedlings is proposed.

1. The utility model is provided with a vertical pipe, a connecting rod, a water wheel fan, an electric telescopic rod, a nozzle, a movable arm, and a hose. The electric telescopic rod is extended or retracted, and can push the nozzle to adjust its angle up and down through the movable arm. According to the change of the elevation angle of the nozzle, the size of the spraying coverage area can be changed. The spraying position can also be flexibly adjusted according to the height of the tomato seedlings. When a large amount of water flows into the vertical pipe, the water flow pressure will drive the water wheel fan to rotate, thereby driving the entire vertical pipe to rotate through the connecting rod, so that the nozzle installed on the vertical pipe can perform 360-degree rotation spraying. In conjunction with the angle adjustment of the nozzle itself, the irrigation mechanism on a vertical pipe can irrigate all directions around without dead angles, greatly improving the practicality of the device. At the same time, it also makes it only necessary to assemble one set of vertical pipes in the same area, greatly saving costs.

2. The utility model can determine the amount of water required for irrigation of a single set of vertical pipes according to the loss of water for watering the surrounding tomato seedlings when the nozzle rotates one circle, through the arrangement of a driving motor, a screw rod, a sealing plate and a guide rod. That is, the driving motor can be started to drive the screw rod to rotate, and the sealing plate can be moved downward under the limit of the guide rod, so as to reduce the water storage space inside the water tower and make the water storage volume inside the water tower just at the water volume required for the number of irrigation circles. When watering the tomato seedlings, quantitative watering can be carried out to avoid excessive watering, which will cause the seedlings to be flooded, and also avoid the waste of water resources.

Furthermore, the electric telescopic rod 6 is rotatably connected to the fixed block 5 below, and the electric telescopic rod 6 is rotatably connected to the nozzle 7. The nozzle 7 is rotatably connected to the fixed block 5 above through the movable arm 8, so that when the electric telescopic rod 6 is extended or contracted, it can push the nozzle 7 to adjust the angle up and down, thereby changing the size of the spraying coverage area, and can also flexibly adjust the spraying position according to the height of the tomato seedlings.

Furthermore, the water turbine fan 4 is located at the internal joint between the riser 2 and the main pipeline 1, and the upper end of the water turbine fan 4 is connected to the top of the inner surface of the riser 2 through the connecting rod 3, and the riser 2 and the main pipeline 1 are rotatably connected through a sealed bearing, so that when the flowing water pressure enters the riser 2, the water pressure can drive the water turbine fan 4 to rotate and then drive the entire riser 2 to rotate through the connecting rod 3, so that the sprinkler 7 rotates and sprays, thereby expanding the irrigation area of the sprinkler 7.

Furthermore, the whole device can be adjusted up and down, and can also be rotated for spraying, so that only one set of vertical pipes 2 needs to be installed in the same area, which greatly saves costs.

Furthermore, the hose 9 transports the water in the vertical pipe 2 to the nozzle 7 for spraying. The hose 9 itself can be twisted at will, and then can cooperate with the up and down adjustment of the nozzle 7 to always maintain a stable water supply.

As shown in Figures 1 and 4, a water pump 10 is fixedly connected to the rear end of the main pipeline 1, and a water tower 11 is provided at the rear end of the water pump 10. The front and lower sides of the outer surface of the water tower 11 are connected to the water pump 10 through a pipeline, and a water injection pipe 12 is connected to the lower left side of the outer surface of the water tower 11. A driving motor 13 is fixedly installed on the top of the outer surface of the water tower 11, and a screw 14 is installed on the output end of the driving motor 13 through the water tower 11.

Furthermore, the guide rod 16 slides through the sealing plate 15 , so that when the screw rod 14 rotates, the sealing plate 15 can stably move downward to avoid rotating with the screw rod 14 .

Furthermore, the sealing plate 15 moves up and down and slides in contact with the inner surface of the water tower 11, which can adjust the water storage space inside the water tower 11 so that the water storage capacity inside the water tower 11 is just the amount of water required for the number of watering circles. When watering the tomato seedlings, quantitative watering can be achieved to avoid excessive watering, which will cause the seedlings to be flooded and also avoid the waste of water resources.

Working principle: When using the quantitative irrigation equipment for tomato seedlings, first, according to the loss of water volume for irrigation of the surrounding tomato seedlings by one rotation of the nozzle 7, the drive motor 13 is started to drive the screw 14 to rotate, and under the limit of the guide rod 16, the sealing plate 15 is moved down to reduce the water storage space inside the water tower 11, so that the water storage volume inside the water tower 11 is just at the required water volume for the number of irrigation circles, and then water is added to the water tower 11 through the water injection pipe 12, and then the water is sucked into the main pipeline 1 through the water pump 10. With the continuous replenishment of the subsequent water flow, the water in the main pipeline 1 will enter the riser 2. At this time The water pressure will drive the water wheel fan 4 to rotate, thereby driving the entire vertical pipe 2 to rotate through the connecting rod 3, and then the sprinkler head 7 installed on the vertical pipe 2 will perform 360-degree rotation spraying. According to the coverage of the sprinkler head 7 on a single side and the growth changes of the tomato seedlings, the electric telescopic rod 6 will extend or contract, and can push the sprinkler head 7 to adjust its angle up and down through the movable arm 8. According to the change of the elevation angle of the sprinkler head 7, the size of the spraying coverage area can be changed, and the spraying position can be flexibly adjusted according to the height of the tomato seedlings. This is the working principle of the tomato seedling quantitative irrigation equipment.
