Description

Technical Field

[0001] The utility model relates to the technical field of irrigation, in particular to a saline-alkali land irrigation device. Background Art

[0002] Generally speaking, saline-alkali land is a general term for saline soil and alkaline soil. Saline soil refers to saline soil with high chloride or sulfate content, but the pH value is not necessarily very high; alkaline soil refers to soil containing carbonate or heavy phosphate, with high pH value and alkaline soil. The soil structure of saline-alkali land is sticky when wet and hard when dry, and the soil has poor water permeability and air permeability. Shrubs, trees, herbaceous plants, etc. planted in saline-alkali land often show problems such as plant wilting, root rot, and seed failure to germinate. For transplanted shrubs and trees, physiological drought and nutrient absorption may be blocked due to excessive salt in the soil, which means that the plants do not grow new roots, or the new roots deteriorate in a short time, resulting in "seedling burn". Although the conditions in saline-alkali land are harsh, some plants can grow in saline-alkali land, such as Robinia pseudoacacia, Salix matsudana, Elaeagnus angustifolia, Paulownia orientalis, etc. among tree species; Amorpha fruticosa, Salix chinensis, and Acidus thornii among shrub species. These plants have a certain adaptability to saline-alkali land and can grow in such an environment, which also helps to improve the soil environment. When planting plants in saline-alkali land, irrigation is a link that requires special attention. The general saline-alkali land irrigation device uses a water pump to extract water from the water source and transmit it through a water pipe, and finally irrigates the planted field. In the prior art, the saline-alkali land irrigation device has the following problems: directly spraying the leaves of plants, some saline-alkali lands may cause soil structure destruction due to salt crystallization, resulting in compaction, and when watering, water easily flows around, resulting in poor watering effect.

[0024] When the saline-alkali land irrigation device is used to irrigate the fruit trees, the saline-alkali land irrigation device is first moved to one side of the fruit trees so that the base 1 of the saline-alkali land irrigation device is facing the roots of the fruit trees. The first hydraulic rod 14 is started, and the telescopic end of the first hydraulic rod 14 is extended to drive the U-shaped frame 4 to slide on the top surface of the top plate 3. The movement of the U-shaped frame 4 drives the driving guide mechanism and the ring arm 7 to move, and the ring arm 7 is moved to the circumference of the fruit tree. Then, the first hydraulic rod 14 is stopped, and the driving guide mechanism is started again. The driving guide mechanism drives the ring arm 7 to rotate clockwise around the center of the ring arm 7 and rotates to the limit position. The second electric push rod 16 is then stopped, and then the second electric push rod, the third electric push rod, the second motor 19 and the third motor 25 are started at the same time. The extension of the telescopic end of the second hydraulic rod 16 drives the first support plate 17 to descend. The descent of the first support plate 17 drives the second shaft 18 to descend. The rotation of the second motor 19 drives the second shaft 18 to rotate. The rotation of the second shaft 18 drives the first spiral blade 20 to rotate.

The rotation of the third shaft 24 drives the second spiral blade 26 to rotate. The second spiral blade 26 drives The movable blade 34 rotates, and the first spiral blade 20 and the second spiral blade 26 drill into the soil around the root of the fruit tree as they continue to descend, loosening the hardened saline-alkali soil. When the first spiral blade 20 and the second spiral blade 26 drill to a certain depth, the second hydraulic rod 16 and the third hydraulic rod 22 are stopped at the same time, and then the driving guide mechanism is started, and the driving guide mechanism drives the ring arm 7 to rotate counterclockwise around the rotation center of the ring arm 7. At this time, the blades 34 at the outer edges of the first spiral blade 20 and the second spiral blade 26 rotate to continuously loosen the soil and simultaneously rotate around the ring arm 7. The rotation center rotates counterclockwise and stops when the ring arm 7 rotates to the extreme position. At this time, the soil on the outer circumference of the root of the fruit tree is loosened and a ring groove is formed. Then the water outlet valve 33 is opened, and the water in the water tank 28 is poured from the water tank 28 to the root of the fruit tree through the water outlet pipe 31. When the water fills the ring groove, the water outlet valve 33 is closed to complete the irrigation operation. The saline-alkali land irrigation device not only loosens the soil compacted on the saline-alkali land, which is beneficial for water to penetrate into the soil and is beneficial for root absorption, thereby improving the irrigation effect, but also the formed ring groove can prevent water from flowing around and avoid waste of water resources.
