Description

Technical Field

[0001] The utility model relates to a drip irrigation type water and fertilizer machine, in particular to a rotary drip irrigation type water and fertilizer machine. Background Technique

[0002] Crop growth requires the provision of various nutrients, and applying fertilizers is one of the commonly used means. With the development of science and technology, people combine water and fertilizers, and liquid fertilizers have emerged. Liquid fertilizers have been widely used in modern agricultural production. The implementation of the water and fertilizer integration technology is a new agricultural technology that integrates irrigation and fertilization. Through pipelines and drippers, drip irrigation is formed to evenly, regularly, and quantitatively infiltrate the root development and growth area of crops, so that the main root soil always remains loose and has an appropriate water content. Such a fertilization method saves labor costs, improves the utilization rate of fertilizers, increases production and income, and improves production efficiency.

[0003] The irrigation pipelines of the existing water and fertilizer machines are not specially arranged. In particular, the laying coverage of the drip irrigation type irrigation pipelines is limited, and the ability to be flexibly arranged is poor. However, some irrigation environments, such as orchard irrigation and greenhouse irrigation, are not suitable for the sprinkler irrigation method, so only the drip irrigation method can be used. The coverage range of the traditional drip irrigation type drippers dripping water and fertilizers drop by drop is also very limited, and the drippers cannot change the direction of their drip irrigation, often resulting in a low irrigation uniformity in the drip irrigation area and affecting the consistency of crop growth. Content of the Utility Model

[0004] In order to solve the deficiencies of the above-mentioned technologies, the utility model provides a rotary drip irrigation type water and fertilizer machine.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a rotary drip irrigation type water and fertilizer machine, including a filter and a fertilizer barrel with fertilizers stored inside. The filter is connected to a water inlet pipe, the other end of the filter is connected to the fertilizer barrel, the other end of the fertilizer barrel is connected to a water and fertilizer integration machine through a mixing suction pipe, the water and fertilizer integration machine is externally connected to a drip irrigation supply main pipe laid in the field, and a number of drip irrigation supply branch pipes scattered in the field are connected to the drip irrigation supply main pipe. Each drip irrigation supply branch pipe is provided with a number of drip irrigation micro-sprinklers. The drip irrigation micro-sprinkler includes a main body upper cover and a rotary sprinkler that is rotatably connected to the main body upper cover under the action of an external force.

[0006] Furthermore, a clamp is arranged on the outer circle of the mixing suction pipe and is connected and fastened to an external frame through the clamp. The maximum inner pipe diameter of the mixing suction pipe is larger than the maximum inner pipe diameter of the water inlet pipe.

[0007] Furthermore, a suction pump is arranged at the connection between the mixing suction pipe and the water and fertilizer integration machine.

[0008] Furthermore, the main drip irrigation supply pipe is a straight pipe, drip irrigation supply branch pipes are arranged on both sides of the main drip irrigation supply pipe in a staggered manner, and a drip irrigation supply branch pipe is also arranged at the free end of the main drip irrigation supply pipe.

[0009] Furthermore, the drip irrigation supply branch pipe is connected to the main drip irrigation supply pipe through a tee joint connecting pipe, the drip irrigation supply branch pipe is in a U shape, and the ends of the U-shaped fork of the drip irrigation supply branch pipe are of a closed structure.

[0010] Furthermore, the number of drip irrigation micro-sprays on each U-shaped fork of the drip irrigation supply branch pipe is the same, and the drip irrigation micro-sprays are arranged with the whole facing upward.

[0011] Furthermore, the drip irrigation micro-spray also includes a main body lower cover connected to the main body upper cover and jointly forming an inner cavity. An opening for accommodating a rotary sprinkler is formed at the upper end of the main body upper cover, and a plunger is communicated with the main body lower cover.

[0012] Furthermore, the diameter of the opening at the upper end of the main body upper cover is smaller than the maximum diameter of the rotary sprinkler. The rotary sprinkler is in a spherical shape with an opening at the lower part and an inner channel opened inside. The other end of the inner channel corresponds to a head end formed on the rotary sprinkler.

[0013] Furthermore, a channel is opened in the plunger and the plunger is inserted on the drip irrigation supply branch pipe through a plugging end at its lower end. A through hole communicated with the channel is opened on the plugging end, and the upper end of the plunger is communicated with the inner channel.

[0014] A rotary drip irrigation type water and fertilizer machine changes the setting form of the traditional drip irrigation pipeline, divides the drip irrigation pipeline into a main pipeline and branch pipelines, has strong laying flexibility, can adapt to the drip irrigation environment of various terrains and landforms, and designs the traditional drip irrigation head. The innovatively designed drip irrigation micro-spray can slightly simulate the effect of sprinkler irrigation, and can manually rotate to change the irrigation direction of the drip irrigation micro-spray, and timely conduct uniform irrigation on all drip irrigation environments in the area, and the effect is very good.

Specific implementation mode

[0019] The present utility model will be further described in detail below with reference to the accompanying drawings and specific implementation modes.

[0020] As Figures 1-3 As shown together, this embodiment relates to a rotary drip irrigation type water and fertilizer machine, including a filter 2 and a fertilizer tank 3 with fertilizer stored inside. The filter 2 and the fertilizer tank 3 are prior arts, and those skilled in the art can purchase them according to the parameters required by the irrigation environment; the filter 2 is connected to a water inlet pipe 1, the other end of the filter 2 is connected to the fertilizer tank 3, the other end of the fertilizer tank 3 is connected to the water and fertilizer integrated machine 7 through a mixing suction pipe 4. The water and fertilizer integrated machine 7 is a prior purchase. Since it is a customized product, there is no fixed model. The water and fertilizer integrated machine 7 is externally connected to a main drip irrigation supply pipe 8 laid in the field. A number of drip irrigation supply branch pipes 9 scattered and laid in the field are connected to the main drip irrigation supply pipe 8. A number of drip irrigation micro-sprinklers 11 are provided on each drip irrigation supply branch pipe 9. The drip irrigation micro-sprinkler 11 includes a main body upper cover 12 and a rotating sprinkler 18 rotatably connected to the main body upper cover 12 under the action of an external force. Here, it should be noted that the rotation of the rotary drip irrigation type water and fertilizer machine achieved by the rotating sprinkler 18 in this embodiment is a passive rotation, that is to say, manual external force intervention is required to adjust the rotation position of the rotating sprinkler 18 to achieve precise irrigation of the irrigation points in the area corresponding to the rotation position, rather than the common 360° self-rotation of the sprinkler irrigation type. Special note.

[0021] Preferably, a clamp 5 is arranged on the outer circle of the mixing suction pipe 4 and is connected and fastened to the external frame through the clamp 5. The maximum inner pipe diameter of the mixing suction pipe 4 is larger than the maximum inner pipe diameter of the water inlet pipe 1. Since the water and fertilizer mixed at the fertilizer tank 3 has more internal substances and is thicker than the water filtered by the filter 2, increasing the inner pipe diameter of the mixing suction pipe 4 is beneficial to the flow of water and fertilizer, making the subsequent drip irrigation process smoother.

[0022] As Figure 1As shown, a suction pump 6 is provided at the connection between the mixed suction pipe 4 and the water and fertilizer integrated machine 7. The suction pump 6 is used to suck the mixed water and fertilizer at the fertilizer barrel 3 through the mixed suction pipe 4. It should be noted that the part between the rear section of the suction pump 6 and the drip irrigation supply main pipe 8 does not pass through the inner cavity of the water and fertilizer integrated machine 7. For example, in the existing water and fertilizer integrated machine 7, there is no inner cavity space, but independent pipes are set to connect with the front-end process and the rear-end process, and the water and fertilizer integrated machine 7 is monitored and connected with its independently set pipes. This is the prior art, and this solution does not modify this part.

[0023] The drip irrigation supply main pipe 8 is a straight pipe. Setting it as a straight pipe is more conducive to the flow of water and fertilizer. The drip irrigation supply branch pipes 9 are arranged in a staggered manner on both sides of the drip irrigation supply main pipe 8, that is, as Figure 1 shown, the drip irrigation supply branch pipes 9 on both sides of the drip irrigation supply main pipe 8 are not differentiated and set at the same position left and right, but are staggered and differentiated left and right. If it is ensured that the water and fertilizer will not have a serious breakpoint at the drip irrigation supply branch pipe 9 at the front-end position during the flow process, affecting the smooth flow of water and fertilizer to the drip irrigation supply branch pipe 9 at the rear section, the free end of the drip irrigation supply main pipe 8 is also provided with a drip irrigation supply branch pipe 9. The specific setting positions of several drip irrigation supply branch pipes 9 are adaptively changed according to the on-site irrigation environment, and this application does not limit it.

[0024] The drip irrigation supply branch pipe 9 is connected to the drip irrigation supply main pipe 8 through a tee connection pipe 10. The drip irrigation supply branch pipe 9 is in a U shape, and the end of the U-shaped bifurcation of the drip irrigation supply branch pipe 9 is a closed structure. Specifically, one end of the tee connection pipe 10 is communicated with the drip irrigation supply main pipe 8, and the other two ends of the tee connection pipe 10 are respectively communicated with the two U-shaped bifurcations of the drip irrigation supply branch pipe 9. Through the accumulation of the number of drip irrigation supply branch pipes 9 and the U-shaped bifurcations of each drip irrigation supply branch pipe 9, the coverage area of drip irrigation is wider, the irrigation effect is better, and the irrigation efficiency is higher.

[0025] The number of drip irrigation micro-sprays 11 on each U-shaped bifurcation of the drip irrigation supply branch pipe 9 is the same. The drip irrigation micro-sprays 11 are arranged facing upwards as a whole. The orientation of the drip irrigation micro-sprays 11 simulates the style of sprinkler irrigation, so that it has the effect of micro-spraying, but essentially it still belongs to the category of drip irrigation. The drip irrigation effect at the drip irrigation points is more uniform. This is hereby explained.

[0026] As Figure 2 shown, the drip irrigation micro-spray 11 further includes a main body lower cover 17 that is connected to the main body upper cover 12 and jointly forms an inner cavity. The positions where the main body upper cover 12 and the main body lower cover 17 are in contact are provided with threaded fittings for screwing (not shown in the figure), and this application does not limit the connection form of the main body upper cover 12 and the main body lower cover 17. Those skilled in the art can also set the connection position of the main body upper cover 12 and the main body lower cover 17 to be connected by snap fit or bonding. An opening for accommodating the rotary nozzle 18 is formed at the upper end of the main body upper cover 12, and the main body lower cover 17 is communicated with the plunger 13.

[0027] The opening diameter at the upper end of the main body upper cover 12 is smaller than the maximum diameter of the rotary nozzle 18. The rotary nozzle 18 is spherical with a lower opening and an inner channel 19 provided inside. Therefore, the spherical main body of the rotary nozzle 18 is restricted within the inner cavity formed by the main body upper cover 12 and the main body lower cover 17, and the upper part of the rotary nozzle 18 extends beyond the opening at the upper end of the main body upper cover 12 as Figure 2 shown. Based on this structure, the rotary nozzle 18 can rotate in the extended area, changing its orientation by rotation. The other end of the inner channel 19 corresponds to the head end formed on the rotary nozzle 18, and the inner channel 19 gradually narrows from the lower side to the upper side.

[0028] A channel is provided inside the plunger 13, and the plunger 13 is inserted onto the drip irrigation supply branch pipe 9 through the plugging end 14 at its lower end. A through port 16 communicating with the channel is provided on the plugging end 14, and the upper end of the plunger 13 communicates with the inner channel 19. Therefore, the water and fertilizer in the drip irrigation supply branch pipe 9 can flow out successively through the plunger 13 and the rotary nozzle 18, achieving the effect of micro-spraying.

[0029] The above embodiments are not limitations to the present invention, and the present invention is not limited to the above examples either. Any changes, modifications, additions or substitutions made by those skilled in the art within the technical scope of the present invention also fall within the protection scope of the present invention.
