Description

Technical Field

[0001] The invention relates to the technical field of drip irrigation and fertilization, in particular to a water-saving drip irrigation device and a drip irrigation method for agricultural fertilization. Background Art

[0002] In agricultural production, traditional fertilization methods often have problems such as low fertilizer utilization, serious waste, and environmental pollution. With the development of science and technology, drip irrigation devices for agricultural fertilization have emerged. Drip irrigation is an irrigation and fertilization method that delivers water and fertilizers to the soil near the roots of crops evenly and accurately at a small flow rate. Fertilization through drip irrigation has the advantages of solving water shortage, improving fertilizer utilization, meeting precision agriculture needs and protecting the environment; The existing drip irrigation device for agricultural fertilization still has the following technical problems when in use, such as: 1. It is not convenient to adjust the position of drip irrigation when using the existing drip irrigation device for agricultural fertilization. This is because the existing drip irrigation device is generally a straight pipe, and the drip irrigation hole is opened on the straight pipe, so the position of the drip irrigation hole is generally fixed. If the position of the drip irrigation hole needs to be adjusted, the straight pipe needs to be bent. However, this method of adjusting the position of the drip irrigation hole easily causes the water in the drip irrigation device to flow unsmoothly, making the drip irrigation operation not smooth enough; 2. Although the existing drip irrigation device for agricultural fertilization can save water resources when in use, it will also cause some water resources to be wasted. This is because in order to avoid the drip irrigation hole from being blocked, the existing drip irrigation device generally opens the drip irrigation hole at the upper surface of the drip irrigation device. This makes it impossible for the water to drip out of the drip irrigation hole when the water level in the drip irrigation device is lower than the drip irrigation hole when water is no longer supplied to the drip irrigation device, thereby causing this part of the water to be evaporated and wasted. In addition, since some water is wasted, the drip irrigation cycle will be reduced, thereby increasing the number of drip irrigations during the growth cycle of the plant, which is not conducive to energy saving. Therefore, a water-saving drip irrigation device for agricultural fertilization is needed to solve the above problems. Summary of the invention

[0003] The purpose of the present invention is to provide a water-saving drip irrigation device and a drip irrigation method for agricultural fertilization, so as to solve the problem mentioned in the above background technology that the existing drip irrigation device for agricultural fertilization is not convenient for adjusting the drip irrigation position and cannot ensure that the water in the drip irrigation device is fully utilized.

[0004] To achieve the above object, the present invention provides the following technical solutions: A water-saving drip irrigation device for agricultural fertilization comprises a drip irrigation pipe, an assembly mechanism and a suction component. The two ends of the drip irrigation pipe are provided with the assembly mechanism, which is used for connecting multiple drip irrigation pipes end to end. The drip irrigation pipe is provided with a suction component, which is used for sucking water in the drip irrigation pipe to achieve the purpose of drip irrigation.

[0005] Furthermore, the assembly mechanism includes a connecting sleeve, a connecting port, a ratchet, a pawl, a torsion spring and a connecting head. The connecting port is arranged at one end of the drip irrigation pipe, and the outer side of the end of the drip irrigation pipe is evenly arranged with ratchets. The outer bearing of the other end of the drip irrigation pipe is connected with a connecting sleeve, and the inner side of one end of the connecting sleeve is connected to the outer side of the other end of the drip irrigation pipe through a torsion spring. The inner side of the connecting sleeve is also evenly distributed with pawls, and the other end of the drip irrigation pipe is provided with a connecting head.

[0006] By adopting the above technical solution, the ratchet and the pawl can be connected by directly sleeved on the outside of the connecting port through the connecting sleeve, and the connecting head and the connecting port can be connected, so that multiple drip irrigation pipes can be connected end to end, so as to facilitate the assembly of drip irrigation pipes of different lengths according to usage needs.

[0007] Furthermore, the connecting head and the connecting port are truncated cone-shaped and matched with each other, and rubber pads are arranged on the outer side of the connecting head and the inner side of the connecting port.

[0008] By adopting the above technical solution, the connector and the connection port can be easily connected, and the tightness of the connection between the connector and the connection port can be ensured by the rubber pad, so that multiple drip irrigation pipes can be stably connected.

[0009] Furthermore, the cross section of the drip irrigation pipe is circular or flat square, and the drip irrigation pipe is spiral.

[0010] By adopting the above technical solution, the flat square cross-section of the drip irrigation pipe can save water resources and reduce the amount of water required when multiple drip irrigation pipes are fully filled.

[0011] Furthermore, the ratchets and pawls are provided in two groups, and the arc angle of each group of ratchets and pawls is less than 90°, the two groups of ratchets are symmetrically arranged about the axis of the connecting port, and the two groups of pawls are symmetrically arranged about the axis of the connecting sleeve.

[0012] By adopting the above technical solution, the connecting head and the connecting port can be stably connected through the connection of the ratchet and the pawl, and the arc angle of the ratchet and the pawl is less than 90°, so that after the connecting sleeve is rotated to a certain angle, the connected ratchet and the pawl can be completely separated, thereby facilitating the separation of the connecting head and the connecting port.

[0013] Furthermore, the suction assembly includes an outer cover tube, an inner cover tube and a hose, the upper surface of the lower end of the spiral structure of the drip irrigation pipe is provided with a hole groove, and the outer cover tube is provided in the hole groove, the outer wall of the outer cover tube is seamlessly and sealedly connected to the opening of the hole groove, and the lower end of the outer cover tube is seamlessly and sealedly connected to the lowest point on the inner side of the drip irrigation pipe, the inner top end of the outer cover tube is coaxially fixedly connected with the inner cover tube, and the upper end of the outer cover tube is higher than the upper surface of the lower end of the spiral structure of the drip irrigation pipe, and a hose is passed through the outer side of the outer cover tube at equal angles above the upper surface of the lower end of the spiral structure of the drip irrigation pipe.

[0014] By adopting the above technical solution, when the drip irrigation pipe is filled with water, the water can flow from the interlayer of the outer cover tube and the inner cover tube to the position of the hose and drip out from the lower end of the hose, thereby realizing drip irrigation operation. Due to the siphon mechanism composed of the outer cover tube, the inner cover tube and the hose, the water in the drip irrigation pipe can drip out from the lower end of the hose as completely as possible.

[0015] Furthermore, the lower end of the inner cover tube is 1-2 mm away from the lower end of the outer cover tube, and the hose is connected to the interlayer between the inner cover tube and the outer cover tube.

[0016] The adoption of the technical solution can facilitate water to enter the hose through the interlayer between the inner cover tube and the outer cover tube.

[0017] Furthermore, the angularly opposite hoses are also provided with an assembly mechanism for connecting the two angularly opposite hoses.

[0018] By adopting the above technical solution, the hoses with opposite angles are connected through an assembly mechanism, so that the position of the drip irrigation can be adjusted according to needs, which is more flexible.

[0019] Furthermore, the drip irrigation pipe is made of rubber, and the outer diameter of the drip irrigation pipe is not greater than 1 cm, and the height of the lower end of the hose is lower than the lowest point of the drip irrigation pipe.

[0020] By adopting the above technical solution, the drip irrigation pipe can be stretched or compressed to achieve the purpose of changing the pitch of the spiral drip irrigation pipe, so that the position of the drip irrigation can be flexibly adjusted.

[0021] A drip irrigation method for agricultural fertilization, comprising:

[0022] Step 1: Connect different numbers of drip irrigation pipes into appropriate lengths through an assembly mechanism as needed, then connect one end of the connected pipe to the water supply end, and then plug the other end of the connected pipe; Step 2: As needed, pull up the pipe to increase or decrease the pitch of the spiral drip irrigation pipe so that the suction assembly can be adjusted to the drip irrigation position; Step 3: Connect the hose that is not in the drip irrigation position and the hose that is in the drip irrigation position but not needed through the assembly mechanism; Step 4: Water is transported into the drip irrigation pipe through the water supply end. After the water flows through the suction component, it will drip out from the lower end of the open hose, thereby achieving drip irrigation; Step 5: After the water supply end delivers water for a period of time, it stops delivering water to the drip irrigation pipe and opens the other end of the blocked pipe. After that, through the spiral structure of the drip irrigation pipe and the suction component, the water in the drip irrigation pipe is almost completely dripped out from the lower end of the hose, thereby avoiding water waste in the drip irrigation pipe.

[0023] Compared with the prior art, the beneficial effects of the present invention are: the water-saving drip irrigation device for agricultural fertilization can not only easily adjust the position of drip irrigation, but also adjust the range of drip irrigation, and can also drip out the water in the drip irrigation pipe as much as possible, so as to make full use of water resources and avoid waste: 1. The spiral drip irrigation pipe can adjust the drip irrigation position by adjusting the pitch, which makes it easy to adjust the drip irrigation position. Since the drip irrigation pipe is spiral, it will not cause the problem of water flowing unsmoothly in the drip irrigation pipe. In addition, the assembly mechanism can not only facilitate the connection of multiple drip irrigation pipes, but also connect hoses with opposite angles, so as to adjust the horizontal and vertical range of drip irrigation. 2. The spiral drip irrigation pipe and the suction assembly can make full use of the water in the drip irrigation pipe, thereby making full use of water resources and avoiding waste of water resources.
