[0002] Orchard irrigation is one of the most important links in the orchard planting process. The traditional irrigation method is often to lay pipes to spray or directly flood the surface of the land where the plants grow. During the irrigation process, there will be problems such as too much irrigation water that cannot be accurately controlled or uneven irrigation.

[0003] In response to the above problems, a utility model patent with publication number CN216362973U discloses a fruit tree spraying device for orchard irrigation. The above technical solution solves the problem that the traditional irrigation method cannot irrigate evenly by arranging a water pump on the mobile body to spray the water in the water tank through the nozzle. However, the following problems still exist in the above technical solution and have not been solved: 1. The device uses the nozzle to spray the plants, and it is difficult to achieve deep watering, and it is impossible to ensure that the water can penetrate deep into the soil, especially short seedling plants (such as watermelon plants, strawberry plants, etc.), which require sufficient watering of their roots growing in the soil, and plastic film is generally laid outside the seedlings when the seedlings are planted.

[0015] A method for irrigating an orchard using an orchard water-saving automatic irrigation system, the specific steps are as follows: S1, adjusting the position: moving the device to both sides of the plants that need to be irrigated, adjusting the overall height of the water injection component by the longitudinal cylinder, and then the transverse cylinder pushes the water injection component out to the appropriate position.

[0016] S2. Irrigation after insertion: After the horizontal cylinder pushes the water injection component to the appropriate position, the downward pressure cylinder extends the water injection barrel assembly to move downward, the soil-moving assembly opens, and the water injection barrel assembly is inserted into the soil near the plants that need to be irrigated. At this time, the pump control assembly pumps out the water in the water tank and transports it to the water injection barrel assembly after pressurization.

[0017] S3. Pump out and clean: When the irrigation reaches a certain amount, the pump control assembly stops supplying water, the downward pressure cylinder retracts to drive the water injection cylinder assembly upward, and then the horizontal cylinder pulls the water injection component back to its original position, and then the carrier drives the entire system forward to the next working position.

[0018] The beneficial effects of the present invention are: 1.

At the same time, the water injection barrel assembly of the present invention can be adjusted in position to prevent it from damaging the plastic film on the outside of the plant, and the brushing assembly provided in the present invention can brush the soil adhered to the water injection barrel assembly to avoid soil clogging the water injection hole.

[0019] Second, the right end of the support box used in the present invention is a closed structure. This special structure can push aside the branches and leaves that interfere with the irrigation of the plants, so that the branches, leaves, weeds and the like on both sides of the carrier will not get caught on the water injection components and affect the irrigation.

[0020] 3. The pump control component used in the present invention can control the water injection volume, and when the water injection cylinder is pulled out after the water injection is completed, the inner water injection cylinder moves upward first, and the rubber ring blocks the water injection hole on the inner water injection cylinder, thereby preventing the water remaining in the water pipe from flowing out after the pump control component stops supplying water during the operation to the next water injection position, effectively avoiding waste in the process from one plant to another, and realizing precise irrigation, so that there is no need to frequently add water to the water tank.

[0021] Fourth, the soil-moving assembly used in the present invention can move the surface soil to form a water storage pit when the water injection tube assembly is inserted. The water stored in the water storage pit can prolong the time for the soil to maintain a high humidity state, reduce the number of watering times, and achieve the purpose of saving water.

The orchard water-saving automatic irrigation system according to claim 1, characterized in that: The outer side surfaces of the inner water injection cylinder (531) and the outer water injection cylinder (532) are both provided with water injection holes (538), and the water injection holes (538) are all arranged in a ring shape; the rubber ring (536) is installed on the inner wall of the outer water injection cylinder (532) and is located above the water injection holes (538) of the outer water injection cylinder (532).

6. The orchard water-saving automatic irrigation system according to claim 2, characterized in that: The brushing disc (542) is an annular structure. The inner ring surface of the brushing disc (542) is evenly provided with wave spikes (543) having the same number as the spiral guide grooves (537). The tips of the wave spikes (543) are rounded and correspond to the spiral guide grooves (537) one by one and are arranged tangent to each other. The inner ring of the brushing disc (542) is also evenly provided with flexible bristles.

7. The orchard water-saving automatic irrigation system according to claim 1, characterized in that: One end of the support box (51) in the right direction is a closing structure, and a closing frame (512) is also arranged at the bottom of the right end of the support box (51).

8. The orchard water-saving automatic irrigation system according to claim 1, characterized in that: The water tank (2) is provided with a waist-shaped groove (21), a glass sheet (22) is installed in the waist-shaped groove (21), and the glass sheet (22) is connected to the inner side of the waist-shaped groove (21) in a water-proof manner.

9. The orchard water-saving automatic irrigation system according to claim 1, characterized in that: The water pipe interface (533) is connected to the pump control component (3) via a hose (56).

10. A water-saving automatic irrigation method for an orchard, characterized in that: The method for irrigating an orchard using the orchard water-saving automatic irrigation system described in any one of claims 1 to 9 comprises the following specific steps: S1. Adjusting the position: Move the device to both sides of the plants to be irrigated, adjust the overall height of the water injection component (5) by the longitudinal cylinder (43), and then push the water injection component (5) to a suitable position by the transverse cylinder (44); S2, irrigation after insertion: after the horizontal cylinder (44) pushes the water injection component (5) to a suitable position, the downward pressure cylinder (511) extends the waiting water injection cylinder assembly (53) to move downward, the soil excavation assembly (55) is opened, and the water injection cylinder assembly (53) is inserted into the soil near the plant to be irrigated. At this time, the pump control assembly (3) pumps out the water in the water tank (2), pressurizes it and delivers it to the water injection cylinder assembly (53); S3, pumping out and cleaning: When the irrigation reaches a certain amount, the pump control assembly (3) stops supplying water, the downward pressure cylinder (511) retracts to drive the water injection cylinder assembly (53) to move upward, and then the horizontal cylinder (44) pulls the water injection component (5) back to the original position, and then the carrier (1) drives the entire system forward to the next working position.
