Description

Technical Field

[0001] The invention relates to the technical field of irrigation devices, and in particular to a forestry seedling raising water-saving irrigation device and an irrigation method. Background Art

[0002] Irrigation is an indispensable part of the forestry seedling raising process. Reasonable irrigation can meet the water requirements of seedling growth, promote the root development and branch and leaf growth of seedlings, and improve the stress resistance and survival rate of seedlings. Irrigation is especially important in arid areas or when cultivating tree species that require more water.

[0003] When forestry seedling irrigation is carried out in the prior art, some seedlings need to be watered once every three days, and some seedlings need to be watered once every two days. This is mainly due to the differences in the water requirements of different tree species, different growth stages and different environmental conditions, and different tree species have different water requirements. Some tree species are naturally drought-resistant, such as Ailanthus altissima, Robinia pseudoacacia, and Syringa syringae, and their water requirements are relatively low, so the watering frequency can be reduced accordingly. Other tree species have higher water requirements, such as some broad-leaved trees or trees in the vigorous growth period, which need to be watered more frequently to meet growth needs, and different tree species have different water requirements. Some tree species are naturally drought-resistant, such as Ailanthus altissima, Robinia pseudoacacia, and Syringa syringae, and their water requirements are relatively low, so the watering frequency can be reduced accordingly. Other tree species have higher water requirements, such as some broad-leaved trees or trees in the vigorous growth period, which need to be watered more frequently to meet growth needs.

[0004] In this way, when raising seedlings, if different types of plant seedlings are raised at the same time, different watering requirements will appear. The irrigation pipes are generally pre-buried and laid, which are inconvenient to replace. However, the types of seedlings are varied. In this way, seedlings with different watering frequencies may be watered with the same irrigation pipe. In this way, every time the seedlings that need to be watered at a high frequency are watered, it is a waste of water for the seedlings that are watered at a low frequency, and it may even cause the seedlings to drown. However, it is too troublesome to temporarily build a irrigation pipe, and if a valve is set separately, it is more troublesome to operate the valve each time. Therefore, in view of the above problems, a forestry seedling water-saving irrigation device and an irrigation method are needed to solve them. Summary of the invention

[0005] The object of the present invention is to provide a forestry seedling water-saving irrigation device and irrigation method to solve the problems raised in the above-mentioned background technology.

[0011] Preferably, the end of the movable rod away from the sealing plug is provided with a ball through a slot for movable engagement, and the ball can replace the movable rod in contact with the extrusion head, thereby avoiding unnecessary friction loss when the extrusion head rotates; when the extrusion head rotates and the groove is aligned with a movable rod, the first spring on the surface of the movable rod will bounce up, and at this time, under the action of the first spring, the movable rod and the sealing plug can be moved backward, so that the sealing plug is moved out of the liquid inlet, so that the irrigation water can flow through the liquid inlet to the area corresponding to the main irrigation water pipe.

[0012] Preferably, the quick connection mechanism includes a connector, a first clamp, a second clamp, a sealing bead, a second spring, and an extrusion rod. The outer surface of the main irrigation water pipe is evenly and movably arranged with a plurality of connectors around it.

Then, when water flows through one of the four flow channel areas divided by the cross partition, the corresponding connector can discharge water. In this way, the four connectors in each group can be connected to a branch pipe for watering one plant respectively, so different plants can be watered at different times; there will be no waste of water resources; and if there are not so many watering needs; there is only one watering need, then other connectors that are not needed can be disconnected from the second clamping ring.

[0015] An irrigation method for a forestry seedling water-saving irrigation device comprises the following steps: The first step is pipeline laying. Before watering forest seedlings, the present invention first lays the main water pipe for watering. Only one main water pipe for watering is needed for each seedling raising area. After the main water pipe for watering is laid, the branch pipe or nozzle for watering can be connected through the connector. When connecting, the branch pipe for watering is set by interference sleeve on the surface of the second clamp ring. Then, the first clamp ring and the second clamp ring are connected together by screwing and clamping the clamping groove and the clamping block of the first clamp ring and the second clamp ring. At this time, the extrusion rod can squeeze the sealing bead downward, so that the connector is turned on, and the laying of the branch pipe for watering is completed.

It should be noted that when the branch pipes for watering are connected, the branch pipes for watering plants with the same watering frequency need to be connected to the surface of the connector on the same side. The second step is to divert watering. When watering is needed, the worm gear reducer can be driven by the second motor to rotate according to the type of plant to be watered. The extrusion plate is then rotated to move the groove on the surface of the extrusion plate to the rear of the corresponding movable rod. At this time, the movable rod can be moved into the groove under the action of the spring, so that the piston can be moved out of the liquid inlet. At this time, the liquid inlet of this area is connected. Subsequently, the water flow pumped into the diversion bin by the booster pump can enter the corresponding flow channel area through the liquid inlet alone. In this way, the flow channel area and the corresponding connected irrigation nozzle can be irrigated alone.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention adds a diversion mechanism to the traditional irrigation system, which can supply water to different areas in one main irrigation water pipe. This can meet the different irrigation needs of different plants. After the pipeline is laid, different plants can share one pipeline, which can achieve better irrigation effect and save water.

[0017] 2. The diversion mechanism of the present invention is easy to control. By driving the extrusion disk to rotate through the second motor, the conduction work of multiple flow channel areas can be controlled, which can greatly reduce the control complexity of the control system of the device. Moreover, by using this control mechanism, it is not only limited to four flow channel areas, but also can conveniently control more flow channel areas, making the scalability of the device very high, and can meet the various irrigation needs of different plants in multiple areas.

[0018] 2. The branch pipe or nozzle for irrigation of the present invention is easy to connect. When connecting, it is only necessary to tighten the first clamp ring and the second clamp ring to each other, so that the corresponding connector can be automatically connected, which is convenient for connection and irrigation.

An irrigation method for a forestry seedling water-saving irrigation device, The first step is pipeline laying. Before watering forestry seedlings, the present invention first lays the main water pipe 3 for watering. Only one main water pipe 3 for watering is needed for each seedling raising area. After the main water pipe 3 for watering is laid, the branch pipe or nozzle for watering can be connected through the connector 801. When connecting, the branch pipe is set by the interference sleeve on the surface of the second clamping ring 803, and then the first clamping ring 802 and the second clamping ring 803 are screwed and engaged with each other through the grooves and blocks of the first clamping ring 802 and the second clamping ring 803.

The second step is watering diversion. When watering is needed, the worm gear reducer 701 can be driven to rotate by the second motor 702 according to the type of plant to be watered. Then, the extrusion plate is rotated to make the groove 705 on the surface of the extrusion plate move to the rear of the corresponding movable rod 604. At this time, the movable rod 604 can move into the groove 705 under the action of the spring 607, so that the piston can be moved out of the liquid inlet 603. At this time, the liquid inlet 603 in this area is connected; then, the water flow pumped into the diversion chamber 601 by the booster pump 501 can enter the corresponding flow channel area through the liquid inlet 603 alone; in this way, the flow channel area and the corresponding connected irrigation nozzle can be watered alone; in this way, the device can be competent for the work of watering plants with different watering frequencies at the same time, without causing waste of water resources and saving water resources; At the same time, since the main water pipe 3 of the present invention can supply water to multiple zones, the device can not only adapt to the different irrigation needs of different plants; it can also connect multiple irrigation nozzles for the seedling cultivation of a plant at the same time. For example, for the same plant, the quick connection mechanism 8 can be used to connect the atomizing nozzle and the drip irrigation nozzle. In this way, when a large area and a large flow of irrigation is required, the atomizing nozzle can be used for irrigation, and when a small flow and a small range of water replenishment is required, the drip irrigation nozzle can be used. In this way, since the device can subdivide the nozzles for irrigation, it can further save water and further improve the irrigation effect of the device.

After the main water pipe (3) is laid, the branch pipe or the nozzle for watering can be connected through the connector (801). When connected, the branch pipe is sleeved by the interference fit on the surface of the second clamping ring (803). Then, the first clamping ring (802) and the second clamping ring (803) are screwed and engaged with each other through the clamping grooves and clamping blocks of the first clamping ring (802) and the second clamping ring (803). At this time, the extrusion rod (806) can squeeze the sealing bead (804) downward, so that the connector (801) is turned on. In this way, the laying of the branch pipe for watering is completed. The second step is watering diversion. When watering is required, the worm gear reducer (701) can be driven to rotate by the second motor (702) according to the type of plant to be watered. Then, the extrusion plate is rotated so that the groove (705) on the surface of the extrusion plate moves to the rear of the corresponding movable rod (604). At this time, the movable rod (604) can move into the groove (705) under the action of the spring (607), so that the piston can be moved out of the liquid inlet (603). At this time, the liquid inlet (603) in this area is connected; then, the water flow pumped into the diversion chamber (601) by the booster pump (501) can enter the corresponding flow channel area through the liquid inlet (603) alone; in this way, the flow channel area and the corresponding connected irrigation nozzle can be watered alone.
