Description

Technical Field

[0001] The invention relates to the field of taro planting, in particular to a taro irrigation device. Background Art

[0002] Taro is a perennial herbaceous plant belonging to the Araceae family. It is often cultivated as an annual crop. Taro was first produced in hot and humid swamps such as China, Malaysia and the Indian Peninsula. It is widely cultivated around the world. my country's taro resources are extremely rich, mainly distributed in the Pearl River and Huaihe River basins. Taro is an important vegetable and food crop with high nutritional and medicinal value. It is a nutritious product suitable for all ages. Moreover, the starch granules of taro are as small as 1 / 10 of potato starch, and its digestibility can reach more than 98%, which is especially suitable for infants and patients. Therefore, it is known as the "Emperor's Offering".

[0003] At present, most taro is also planted in greenhouses. The taro planting process requires spraying and watering. Therefore, a spray device is installed inside the planting greenhouse. However, the existing spray device is usually fixed inside the greenhouse and cannot be adjusted. When the taro branches and leaves grow up, because its branches and leaves are long and large, similar to lotus leaves, when the traditional spray device is used for spraying, the taro leaves will block most of the spray water. The spray water will flow along the taro leaves to the planting gaps, and cannot be directly poured on the roots of the taro, resulting in uneven spray watering, affecting the effect of spray watering.

[0037] A water-proof cover 23 is fixedly sleeved on the outside of the rotating end of the rotary joint 19, and a gear ring 24 is also fixedly sleeved on the outside of the rotating end of the rotary joint 19. The outer side of the gear ring 24 is meshed with a driving gear 25. The driving gear 25 is fixedly mounted on the output shaft of a small motor 26. The small motor 26 is fixed to one side of the telescopic component through a box body;

[0038] A plurality of soil moisture sensors 27 are arranged inside the planting shed 1, and the detection end of each soil moisture sensor 27 is plugged into the inside of the taro planting soil. Considering that most taro is currently planted in a greenhouse, spraying and watering are required during the taro planting process. Therefore, a spraying device is arranged inside the planting greenhouse. However, the existing spraying device is usually fixedly installed inside the greenhouse and cannot be adjusted. When the taro branches and leaves grow up, because the branches and leaves are long and large, similar to lotus leaves, when a traditional spraying device is used for spraying, the taro leaves will block most of the spraying water, and the spraying water will flow along the taro leaves to the planting gap, and cannot be directly poured on the root of the taro, resulting in uneven spraying and watering, affecting the effect of spraying and watering. At the same time, the spraying water flows in one direction along the taro leaves, which will cause scouring of the land, resulting in different hardness of the soil inside the greenhouse, and will also cause unevenness of the soil. The present invention uses a first driving motor 11 and a driving gear 12, the first transmission rack 13, and the telescopic component drive the atomizing nozzle 20 used for irrigation to rise and fall. When the atomizing nozzle 20 rises and falls, the atomizing nozzle 20 moves to the bottom of the wide leaf surface of the taro to directly irrigate and spray the root of the taro, and the first driving motor 11, the driving gear 12, and the first transmission rack 13 can be initially lifted and lowered, and the telescopic component can be used for secondary lifting, thereby ensuring that the atomizing nozzle 20 can adapt to taro leaves of different heights in the growth stage; secondly, in order to improve the planting and cultivation effect of taro, the first driving motor 11 and the second transmission gear are used in conjunction with the fertilizer head 21 to fertilize the soil for planting taro. The fertilizer head 21 will penetrate into the interior of the soil, and then the fertilizer liquid in the proportioning box can be transported through the fertilizer hole, so as to irrigate the planting soil with the fertilizer liquid, and in order to facilitate the user to proportion the fertilizer liquid, a proportioning box is designed, and whether the soil needs irrigation can be detected by the soil moisture sensor 27.

[0039] The other end of the L-shaped connector 18 for connecting the fertilizing head 21 is connected to the fertilizing pipe 9 through the telescopic tube 28, and the other end of the L-shaped connector 18 for connecting the rotary joint 19 is connected to the irrigation pipe 8 through the telescopic tube 28. The telescopic tube 28 is provided to adapt the lifting and lowering movement of the crossbeam 2 and the first transmission rack 13.

[0040] A partition is provided inside the liquid storage tank 4, and a cavity for storing irrigation liquid is provided below the partition.

A boosting liquid pump 30 is also installed on the upper end of the partition. The negative pressure end of the boosting liquid pump 30 passes through the negative pressure pipe to the inside of the cavity, and the delivery end of the boosting liquid pump 30 is connected to the injection port of the first multi-way pipe 6 through a pipeline. The first liquid replenishing valve 29 is provided to replenish the inside of the liquid storage tank 4. The existence of the boosting liquid pump 30 allows the irrigation liquid to be pressurized and delivered to the irrigation pipe 8 and irrigated using the atomizing nozzle 20.

[0041] A transverse plate is provided inside the liquid distribution box 5, and a first negative pressure pump 31 is installed on one side above the transverse plate.

The upper end of the first negative pressure pump 31 is connected with the injection port of the second multi-way tube 7 through a pipeline. A second negative pressure pump 32 is installed at the upper end of the transverse plate. The negative pressure end of the second negative pressure pump 32 passes through the suction pipe 33 to the outside of the liquid distribution box 5. The delivery end of the second negative pressure pump 32 passes through the bottom of the transverse plate through a pipeline and is located inside the liquid distribution chamber. The upper end of the transverse plate is connected with a second liquid replenishing valve 34. The second liquid replenishing valve 34 is provided to transport and dilute the proportioned fertilizer solution in the liquid distribution box 5.
