Description

TECHNICAL FIELD

[0001] The present application relates to the field of agricultural irrigation technology, in particular to a multi-angle irrigation device. BACKGROUND

[0002] Since crops can absorb nutrients not only through roots but also through leaves, fertilizing on the surface of crop leaves is also a way to supplement nutrients for crops, which is called foliar fertilizer.

[0003] Among them, foliar fertilizer is an extra-radical topdressing, which is sprayed directly on the surface of crop leaves and absorbed by leaves to transport nutrients to all parts of the body. Foliar fertilizer mainly plays a role in making up for the insufficient root fertilization, balancing crop nutrition, or temporarily relieving the shortage in a certain growth period of crops. At the same time, leaves directly absorb and utilize effective nutrients, which has a high utilization rate of nutrients and avoids the reduction of fertilizer effectiveness due to the fixation of some nutrients in the soil.

[0004] The existing irrigation device can only irrigate and fertilize the roots of crops, and cannot fertilize the leaves of crops with high height. Therefore, the irrigation device cannot apply foliar fertilizer to the leaves of crops, so that the demand for nutrients during the growth and development of crops cannot be met in time. At the same time, the existing irrigation device can only irrigate and fertilize the roots of crops. If it is necessary to fertilize the leaves of crops with high height, it can only rely on manual fertilization, which is time-consuming and laborious. CONTENT OF THE INVENTION

[0025] The following description is intended to disclose this application and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

[0026] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0027] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0028] refer to Figures 1 to 8 A preferred embodiment of the multi-angle irrigation device according to this application will be described in detail below, wherein the multi-angle irrigation device includes a device body 10 and at least one integrated adjustable spray unit 20.

[0029] Specifically, the volume-adjustable spraying unit 20 includes an extension mechanism 21, a liquid outlet 22, and a lifting mechanism 23. The extension mechanism 21 has a built-in channel through which the liquid to be sprayed is introduced. The liquid outlet 22 is disposed on the extension mechanism 21, and the channel formed by the liquid outlet 22 communicates with the built-in channel of the extension mechanism 21, so as to spray the liquid to be sprayed from the built-in channel through the liquid outlet 22. The lifting mechanism 23 is disposed on the device body 10, and the extension mechanism 21 is disposed on the lifting mechanism 23, so that the lifting mechanism 23 controls the movement of the liquid outlet 22 on the extension mechanism 21 in the direction of gravity, thereby controlling the height of the liquid to be sprayed through the liquid outlet 22.

[0030] It is worth mentioning that, since the height of the liquid outlet 22 is adjustable in the direction of gravity, the liquid to be sprayed in the built-in channel can be sprayed onto the leaf surfaces of crops at different heights, eliminating the need for manual spraying and saving time and effort. In other words, when the liquid to be sprayed is foliar fertilizer, the adjustable height of the liquid outlet 22 allows for spraying foliar fertilizer onto the leaf surfaces of crops at different heights, thus meeting the nutrient requirements of crops during their growth and development.

[0031] Preferably, the extension mechanism 21 includes a connecting seat 211, a vertical extension arm 212, and a horizontal extension arm 213. The vertical extension arm 212 is disposed on the lifting mechanism 23 via the connecting seat 211. One end of the horizontal extension arm 213 is disposed on the vertical extension arm 212, and the horizontal extension arm 213 extends away from the vertical extension arm 212, forming the built-in channel along the extending direction. The liquid outlet 22 is disposed on the other end of the horizontal extension arm 213, and the channel formed by the liquid outlet 22 communicates with the built-in channel.

[0032] Preferably, the liquid outlet 22 is implemented to include a nozzle.

[0033] In this embodiment, the vertical extension arm 212 is implemented as a column, and the vertical extension arm 212 extends upward along the direction of gravity. The connecting seat 211 is disposed at one end of the vertical extension arm 212, and the horizontal extension arm 213 is disposed at the other end of the vertical extension arm 212 away from the connecting seat 211.

[0034] As a deformable embodiment, the vertical extension arm 212 is implemented to include a telescopic cylinder, and the horizontal extension arm 213 is disposed at the output end of the vertical extension arm 212, so that under the combined action of the lifting mechanism 23 and the vertical extension arm 212, the adjustable height of the liquid outlet 22 disposed on the horizontal extension arm 213 is raised, thereby allowing the liquid to be sprayed in the built-in channel to be sprayed out through the liquid outlet 22 to a higher crop leaf surface.

[0035] Specifically, the end of the lateral extension arm 213 is hinged to the vertical extension arm 212 so that when the lateral extension arm 213 rotates about the end hinged to the vertical extension arm 212, the position of the liquid outlet 22 in the direction of gravity of the lateral extension arm 213 is adjusted to adapt to more diverse actual situations.

[0036] The extension mechanism 21 further includes at least one lifting-rotation drive member 214. The lifting-rotation drive member 214 includes a lifting-rotation drive element 2141 and a push-pull element 2142. The lifting-rotation drive member 214 is disposed on the plane swept by the transverse extension arm 213 when it rotates around its hinged end to the vertical extension arm 212. The push-pull element 2142 is disposed on the lifting-rotation drive member 2141 in a direction movable away from the lifting-rotation drive member 2141. The end of the lifting-rotation drive member 2141 away from the push-pull element 2142 is movably hinged to the vertical extension arm 212, and the end of the telescopic end 2142 away from the lifting-rotation drive member 2141 is movably hinged to the transverse extension arm 213.

[0037] As an example, on the one hand, such as Figure 6 As shown, the lifting mechanism 23 adjusts the position of the connecting seat 211 in the direction of gravity. Simultaneously, when the lifting and rotating drive 2141 drives the push-pull member 2142 to move closer to the lifting and rotating drive 2141, the push-pull member 2142 will cause the horizontal extension arm 213 to rotate clockwise around its hinged end to the vertical extension arm 212. At the same time, the lifting and rotating drive 2141 and the push-pull member 2142 will rotate around their hinged ends to the vertical extension arm 212 and the horizontal extension arm 213, respectively, so that the liquid outlet 22 located on the horizontal extension arm 213 is directed towards the roots of the crop, facilitating the spraying of the liquid to be sprayed from the built-in channel to the roots of the crop. When the liquid to be sprayed is fertilizer, root fertilization of the crop can be achieved.

[0038] On the other hand, such as Figure 7As shown, the lifting mechanism 23 adjusts the position of the connecting seat 211 in the direction of gravity. Simultaneously, when the lifting and rotating drive 2141 drives the push-pull member 2142 away from the lifting and rotating drive 2141, the push-pull member 2142 pushes the horizontal extension arm 213 to rotate counterclockwise around its hinged end to the vertical extension arm 212. At the same time, the lifting and rotating drive 2141 and the push-pull member 2142 rotate around their hinged ends to the vertical extension arm 212 and the horizontal extension arm 213, respectively, so that the liquid outlet 22 located on the horizontal extension arm 213 faces the lower surface of the crop leaves, facilitating the spraying of the liquid to be sprayed from the built-in channel onto the lower surface of the crop. When the liquid to be sprayed is fertilizer, foliar fertilizer can be sprayed onto the lower surface of the crop leaves.

[0039] On the other hand, such as Figure 8 As shown, the lifting mechanism 23 adjusts the position of the connecting seat 211 in the direction of gravity. Simultaneously, when the lifting and rotating drive 2141 drives the push-pull member 2142 to move closer to the lifting and rotating drive 2141, the push-pull member 2142 will cause the horizontal extension arm 213 to rotate clockwise around its hinged end to the vertical extension arm 212. At the same time, the lifting and rotating drive 2141 and the push-pull member 2142 will rotate around their hinged ends to the vertical extension arm 212 and the horizontal extension arm 213, respectively, so that the liquid outlet 22 located on the horizontal extension arm 213 faces the upper surface of the crop leaves, facilitating the spraying of the liquid to be sprayed from the built-in channel onto the upper surface of the crop. When the liquid to be sprayed is fertilizer, foliar fertilizer can be sprayed onto the upper surface of the crop leaves.

[0040] Therefore, when the liquid to be sprayed from the built-in channel through the liquid outlet 22 is fertilizer, this technical solution can achieve fertilization of the crop roots and foliar fertilizer application to the upper and lower surfaces of the crop leaves, saving time and effort and reducing labor costs.

[0041] Preferably, the lifting and rotating drive component 214 is implemented as a telescopic cylinder.

[0042] In this embodiment, the lifting mechanism 23 includes a lifting body 231, at least one lifting drive unit 232, at least one lifting screw 233, and at least one lifting actuator 234. The lifting body 231 is mounted on the device body 10, and the lifting body 231 forms a limiting groove 23101 along the direction of gravity. The lifting drive unit 232 is disposed on the lifting body 231. The lifting screw 233 is rotatably disposed at the output end of the lifting drive unit 232 in a manner consistent with the extending direction of the limiting groove 23101. The lifting actuator 234 is penetrated by the lifting screw 233, and the lifting actuator 234 passes through the limiting groove 23101 in a manner adapted to fit the limiting groove 23101. The connecting seat 211 is connected to the lifting actuator 234.

[0043] It is understood that when the lifting drive unit 232 drives the lifting screw 233, the lifting drive member 234, which is penetrated by the lifting screw 233, passes through the limiting groove 23101 in a manner that is adapted to the limiting groove 23101. The lifting drive member 234 will be restricted from rotating by the limiting groove 23101, thereby causing the lifting drive member 234 to drive the connecting seat 211 to move along the extension direction of the limiting groove 23101. In this way, the lifting drive member 234 drives the extension mechanism 21 as a whole to move in the direction of gravity, thereby adjusting the height of the liquid sprayed through the liquid outlet 22.

[0044] Alternatively, the lifting mechanism 23 may be implemented to include a telescopic cylinder, and the connecting seat 211 is disposed at the output end of the lifting mechanism 23 in a manner movable in the direction of gravity.

[0045] Preferably, the lifting drive unit 232 is implemented as including a motor. The lifting screw 233 is implemented as including a screw.

[0046] Preferably, the multi-angle irrigation device further includes a suction assembly 30. The suction assembly 30 is used to deliver the liquid to be sprayed into the built-in channel formed by the lateral extension arm 213.

[0047] More preferably, the suction assembly 30 includes a suction member 31, a liquid suction pipe 32, and a liquid outlet connecting pipe 33. The suction member 31 is located near the extension mechanism 21 and has a suction port and a liquid outlet. The end of the liquid suction pipe 32 is connected to the suction member 31, and the channel formed by the liquid suction pipe 32 communicates with the suction port of the suction member 31. The two ends of the liquid outlet connecting pipe 33 are respectively connected to the suction member 31 and the lateral extension arm 213, and the liquid outlet of the suction member 31 communicates with the built-in channel through the channel formed by the liquid outlet connecting pipe 33.

[0048] It is understood that after the suction port of the suction member 31 draws the liquid to be sprayed into the suction member 31 through the channel formed by the liquid extraction pipe 32, the liquid to be sprayed will sequentially pass through the liquid outlet of the suction member 31, the channel formed by the liquid outlet connecting pipe 33 and the built-in channel and be sprayed out from the liquid outlet member 22.

[0049] Preferably, the suction element 31 is implemented as a water pump.

[0050] Preferably, the multi-angle irrigation device further includes a liquid storage component 40. The liquid storage component 40 includes at least one storage element 41. The storage element 41 is disposed on the device body 10, and the storage element 41 has a storage space 4101 for storing the liquid to be sprayed.

[0051] Specifically, the suction port of the suction member 31 is connected to the storage space 4101 through the channel formed by the liquid extraction pipe 32, so that the suction port of the suction member 31 can draw the liquid to be sprayed in the storage space 4101 into the suction member 31 through the channel formed by the liquid extraction pipe 32, and then the liquid to be sprayed is sprayed out from the liquid outlet 22 through the liquid outlet, the channel formed by the liquid outlet connecting pipe 33 and the built-in channel in sequence.

[0052] It is worth mentioning that, due to the configuration of the storage component 41, there is no need to extend the length of the liquid extraction pipe 32. The liquid to be sprayed can be supplied to the built-in channel through the suction component 31 and the liquid outlet connecting pipe 33, saving space and making it more convenient.

[0053] Preferably, the storage member 41 has an opening 411, which is configured as an opening communicating with the storage space 4101 to allow liquid to be sprayed to be placed into the storage space 4101 through the opening 411.

[0054] Preferably, the liquid storage assembly 40 further includes a liquid storage drive 42, a liquid suction pipe 43, and a liquid discharge pipe 44. The liquid storage drive 42 is disposed near the storage component 41, and the liquid storage drive 42 has a liquid suction port and a liquid discharge port. One end of the liquid suction pipe 43 forms a channel and is connected to the liquid suction port of the liquid storage drive 42. The two ends of the liquid discharge pipe 44 form a channel and are respectively connected to the liquid discharge port of the liquid storage drive 42 and the storage space 4101.

[0055] It is understood that after the liquid suction port of the liquid storage drive 42 draws the external liquid to be sprayed into the liquid storage drive 42 through the liquid suction pipe 43 forming a channel, the liquid to be sprayed will enter the storage space 4101 through the channel formed by the drain port and the drain pipe 44 in sequence, so as to achieve the purpose of storing the liquid to be sprayed into the storage space 4101.

[0056] Preferably, the liquid storage drive 42 is implemented as a water pump.

[0057] Preferably, the multi-angle irrigation device further includes a movable component 50. The movable component 50 is disposed on the device body 10 to support the movement of the device body 10.

[0058] In this embodiment, the moving component 50 includes a directional moving member 51 and a steering moving member 52. The directional moving member 51 includes a directional rolling element 511 and a directional driving unit 512. The directional rolling element 511 is rotatably disposed on the directional driving unit 512, and the directional driving unit 512 is mounted on the device body 10.

[0059] The directional rolling element 511 is implemented as a tire, and the directional drive unit 512 is implemented as a drive motor. The steering moving member 52 is implemented as a steering mechanism.

[0060] It is understood that the directional drive unit 512 provides moving power to the multi-angle irrigation device by driving the directional rolling element 511, and moves the multi-angle irrigation device to a predetermined position by changing the rolling direction of the directional drive unit 512.

[0061] Alternatively, the moving assembly 50 includes a directional moving member 51 and a steering moving member 52, both of which are mounted on the device body 10. The directional moving member 51 is implemented to include directional wheels, and the steering moving member 52 is implemented to include omnidirectional wheels.
