[0024] A specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation.

[0025] In the description of the present invention, it is to be understood that the terms “center”, “longitudinal”, “lateral”, “length”, “width”, “thickness”, “up”, “down”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, “axial”, “radial”, “circumferential”, etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the technical solutions of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0026] In the description of the embodiments of the present invention, unless otherwise specified, “plurality” means two or more.

[0027] like Figure 1 , 2 As shown, an embodiment of the present invention provides a handheld fertilizing device for farmland, including a cylindrical fertilizer mixing barrel 1, a stirring component, a plurality of identical feeding components, a fertilizer suction component and a mobile control terminal 21, wherein the stirring component is fixed above the fertilizer mixing barrel 1, and is used to stir the fertilizer in the fertilizer mixing barrel 1, each feeding component is connected to the upper end of the fertilizer mixing barrel 1, and is used to add fertilizer to the fertilizer mixing barrel 1, one end of the fertilizer suction component extends into the fertilizer mixing barrel 1, and the other end is connected to the drip irrigation device, and is used to pump water and fertilizer in the fertilizer mixing barrel 1 to the drip irrigation device, the fertilizer suction component includes a fertilizer suction pipe 2, a fertilizer delivery pipe 3, a fertilizer suction pump 4 and a first meter 5, the fertilizer suction pipe 2 is located in the fertilizer mixing barrel 1, one end extends out of the fertilizer mixing barrel 1 and is connected to the suction end of the fertilizer suction pump 4, the first meter 5 is arranged at the suction end of the fertilizer suction pump 4, and is used to measure the amount of water and fertilizer for fertilization, the discharge end of the fertilizer suction pump 4 is connected to the fertilizer delivery pipe 3, and the mobile control terminal 21 is connected to the stirring component, the fertilizer suction pump 4 and the first meter 5.

[0028] It can be understood that the present invention delivers a variety of fertilizers into the mixing bucket 1 through the feeding component, then adds water, and then controls the stirring component through the mobile control terminal 21 to stir the various fertilizers and water to form water-fertilizer. The mobile control terminal 21 then controls the fertilizer suction pump 4 to transport the water and fertilizer in the mixing bucket 1 to the farmland. The first meter 5 measures the amount of fertilizer. When the amount of fertilizer reaches a preset value, the mobile control terminal 21 controls the fertilizer suction pump 4 to stop working, which can accurately control the amount of fertilizer, so that crops have the best overall growth environment.

[0029] Furthermore, the mobile control terminal 21 can calculate the fertilizer ratio and the required fertilizer amount according to the crop types and acres, so that the staff can directly prepare the fertilizer according to the calculation results.

[0030] In the embodiment of the present invention, it also includes a water injection pipe 6 and a three-way valve 7. One end of the water injection pipe 6 is connected to the fertilizer absorption pipe 2 through the three-way valve 7, and the other end is connected to the water supply device. The three-way valve 7 and the water supply device are both connected to the mobile control terminal 21.

[0031] It should be noted that the water supply device is a prior art, and as long as the water supply can be controlled, the present invention will not describe it in detail.

[0032] It can be understood that the mobile control terminal 21 can control the water supply device to provide water.

[0033] It can be understood that the three-way valve 7 can control the passage between the water injection pipe 6 and the fertilizer absorption pipe 2.

[0034] When water injection is required, the passage in the direction of the fertilizer suction pump 4 is closed by the three-way valve 7, and then water is injected into the fertilizer mixing barrel 1 through the water injection pipe 6 and the fertilizer suction pipe 2. When fertilization is required, the passage in the direction of the water injection pipe 6 by the three-way valve 7 is closed, and the fertilizer suction pipe 2 and the fertilizer suction pump 4 cooperate to suck out the water and fertilizer in the fertilizer mixing barrel 1. After fertilization is completed, the passage in the direction of the fertilizer mixing barrel 1 by the three-way valve 7 is closed, and then water is injected to clean the fertilizer suction pump 4. Since fertilizer is corrosive, if the fertilizer suction pump 4 is not cleaned, it is easy to cause damage to the fertilizer suction pump 4 or reduce its service life.

[0035] Furthermore, in the embodiment of the present invention, a fourth meter 8 is also included. The fourth meter 8 is arranged on the water injection pipe 6 and is used to measure the amount of water injected into the fertilizer mixing barrel 1.

[0036] Furthermore, in the embodiment provided by the present invention, a filter screen 9 is provided at the lower end of the fertilizer suction pipe 2 to prevent impurities in the fertilizer mixing barrel 1 from entering the fertilizer suction pump 4 and damaging the fertilizer suction pump 4 or reducing the service life of the fertilizer suction pump 4.

[0037] like Figure 1 As shown, in the embodiment provided by the present invention, the feeding assembly includes a fertilizer hopper 10, a feed pipe 11, a solenoid valve 24 and a second meter 22, the upper end of the feed pipe 11 is connected to the discharge port at the lower end of the fertilizer hopper 10, and the lower end extends into the mixing fertilizer barrel 1, the solenoid valve 24 and the second meter 22 are both arranged on the feed pipe 11, and are both communicatively connected to the mobile control terminal 21, the mobile control terminal 21 communicates to control the solenoid valve 24 to open or close according to the amount of fertilizer added by the second meter 22, wherein the lower end of the fertilizer hopper 10 is higher than the upper end of the mixing fertilizer barrel 1.

[0038] It can be understood that the structure of this feeding assembly is suitable for fields with height differences or slopes. Since the present invention has the characteristic of being portable, the volume of the fertilizer mixing barrel 1 is not large, and thus the barrel mouth is also small. If fertilizer is poured directly, it is easy to spill and it is inconvenient to operate in fields with height differences. Therefore, the height of the fertilizer hopper 10 is higher than the height of the fertilizer mixing barrel 1.

[0039] Furthermore, in the embodiment provided by the present invention, a vibrator 12 is provided on the outer wall of the fertilizer hopper 10, and the vibrator 12 is communicatively connected with the mobile control terminal 21. When the mobile control terminal 21 controls the addition of fertilizer, the vibrator 12 is turned on at the same time to assist the fertilizer to enter the mixing bucket 1 from the fertilizer hopper 10.

[0040] It is understandable that since some fertilizers have a certain humidity, they cannot enter the fertilizer mixing barrel 1 smoothly, and the vibrator 12 is added to vibrate the fertilizer hopper 10 to assist.

[0041] like Figure 2 As shown, in the embodiment provided by the present invention, the feeding assembly includes a fertilizer trough 13, a suction pump 16 and a third meter 23, the suction end of the suction pump 16 extends into the fertilizer trough 13 through the first suction pipe 14, the discharge end of the suction pump 16 extends into the fertilizer mixing barrel 1 through the second suction pipe 15, and the third meter 23 is arranged at the discharge end of the suction pump 16, the suction pump 16 and the third meter 23 are both communicatively connected with the mobile control terminal 21, and the mobile control terminal 21 controls the suction pump 16 to be turned on or off according to the amount of fertilizer added by the third meter 23.

[0042] It can be understood that for leveling the field, placing the feeding assembly on the ground and using suction to suck the fertilizer into the fertilizer mixing barrel 1 can reduce the labor of the staff.

[0043] like Figure 1 , Figure 2 As shown, in the embodiment provided by the present invention, the stirring assembly includes a fixed plate 17, a motor 18, a stirring rod 19 and a plurality of stirring blades 20, the fixed plate 17 is fixed to the upper end of the mixing barrel 1, the motor 18 is fixed above the fixed plate 17, the stirring rod 19 is located in the mixing barrel 1 and one end passes through the fixed plate 17 and is connected to the output shaft of the motor 18, a plurality of stirring blades 20 are fixed on the stirring rod 19, and the motor 18 is connected to the mobile control terminal 21.

[0044] It can be understood that the stirring assembly stirs the various fertilizers and water in the fertilizer mixing barrel 1 by driving the stirring blades 20 on the stirring rod 19 through the electric motor 18.

[0045] The invention also provides a control system, which comprises a fertilizer mixing system, a feeding system, a stirring system and a fertilizing system.

[0046] The fertilizer distribution system calculates the required fertilizer types and weights of various fertilizers according to the types of crops and the fertilization area; the feeding system quantitatively delivers different types of fertilizers to the mixing bucket 1 through multiple feeding components according to the fertilizer types and weights of various fertilizers calculated by the fertilizer distribution system, and feeds back to the stirring system after the delivery is completed; the stirring system stirs the fertilizer in the mixing bucket 1 through the stirring component, and feeds back to the fertilization system after the stirring is completed. The fertilization system sets the fertilization start time and fertilizer amount, and starts the fertilizer suction pump 4 to start fertilization after the set time arrives. The fertilizer suction pump 4 sucks the fertilizer in the mixing bucket 1 through the fertilizer suction pipe 2 and transports it to the farmland through the fertilizer delivery pipe 3. At the same time, the first metering meter 5 measures the fertilizer amount. When the fertilizer amount reaches the preset value, the fertilizer suction pump 4 is turned off.

[0047] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0048] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and the embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily realized. Therefore, without departing from the general concept defined by the claims and equivalent scope, the present invention is not limited to the specific details and the illustrations shown and described here.
