[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Combine the following Figures 1 to 6 , describing an embodiment of the present invention.

[0033] The present invention provides a handheld injection fertilization device, comprising: an injection tube 1, a drill bit 3, a handheld frame 4, a motor 5, a piston 6 and a piston rod 7. The injection tube 1 is hollow in structure, and is used to contain fertilizer. The bottom end of the injection tube 1 is closed, and the top end is open. A fertilization hole 9 is opened on the side wall of the injection tube 1; the top end of the drill bit 3 is fixedly arranged at the bottom end of the injection tube 1; the injection tube 1 can be rotatably arranged on the handheld frame 4; the motor 5 is fixedly arranged on the handheld frame 4 and is configured to drive the injection tube 1 to rotate; the piston 6 can be inserted into the injection tube 1 from the top end of the injection tube 1; when the piston 6 is in the injection tube 1, it can move along the length direction of the injection tube 1; the lower end of the piston rod 7 is fixedly connected to the piston 6, and the top end is configured with a handheld part.

[0034] The diameter of the injection tube 1 in the handheld injection fertilization device provided by the present invention is less than 3 cm, and only one motor 5 is provided to drive the injection tube 1 to rotate, while the up and down movement of the piston 6 and the up and down movement of the injection tube 1 rely on manual drive, which greatly reduces the weight of the handheld injection fertilization device, thereby meeting the purpose of handheld injection fertilization, and precisely because of the high flexibility of hand-held, it is convenient to accurately fertilize the plant root system.

[0035] It can be understood that the smaller the diameter of the injection tube 1 is, the smaller the motor 5 required is, and the more convenient it is to hold in hand.

[0036] In some embodiments, the motor 5 is a double-axle hollow shaft motor; the injection tube 1 is passed through and fixed in the hollow shaft of the double-axle hollow shaft motor.

[0037] This embodiment achieves the purpose of driving the injection tube 1 to rotate and making the center of the motor 5 located at the center of the entire fertilizing device as much as possible, so as to facilitate manual hand-holding and reduce the difficulty of fertilizing.

[0038] In addition, a conventional solid shaft motor can also be used in conjunction with a gear set to drive the syringe 1 to rotate. Specifically, the solid shaft motor is fixedly connected to the handheld frame 4, and a driving gear is fixedly connected to the driving shaft of the solid shaft motor. The driving gear is meshed with the driven gear, and the driven gear is coaxially sleeved and fixed outside the syringe 1. The solid shaft motor drives the driving gear to rotate and drives the driven gear and the syringe 1 to rotate.

[0039] Furthermore, you can directly select a standard part sold on the market, such as a hollow rotating module to drive the syringe 1 to rotate; specifically, the hollow rotating module has a hollow hole, the syringe 1 is fixedly installed in the hollow hole, and the hollow rotating module is fixed on the handheld frame 4.

[0040] In some embodiments, a handle 2 is configured on the top of the handheld frame 4 .

[0041] This embodiment is convenient for manual hand-held pressing and lifting.

[0042] In some embodiments, a spiral protrusion 8 is disposed around the injection tube 1 .

[0043] This embodiment facilitates loosening of the soil and downward movement of the injection tube 1 .

[0044] In some embodiments, the drill bit 3 is detachably connected to the injection tube 1 .

[0045] This embodiment facilitates the replacement of the drill bit 3. Specifically, the drill bit 3 can be threadedly connected to the injection tube 1, but the direction of the threaded connection needs to ensure that the drill bit 3 and the injection tube 1 are not loosened when the injection tube 1 is rotated downward to drill a hole; in addition, the drill bit 3 can also be connected to the injection tube 1 by bolts.

[0046] Of course, the drill bit 3 and the injection tube 1 can also be directly welded and fixed.

[0047] In some embodiments, the motor 5 has forward and reverse rotation functions.

[0048] When this embodiment is implemented, when drilling, the motor 5 is started, and the motor 5 drives the injection tube 1 to rotate forward. At the same time, the hand-held frame 4 is manually pressed down, and the hand-held frame 4 drives the injection tube 1 and the drill bit 3 to drill downward; after fertilization is completed, the motor 5 is started and the injection tube 1 is controlled to reverse, and the hand-held frame 4 is lifted up at the same time, and the hand-held frame 4 drives the injection tube 1 and the drill bit 3 to move upward.

[0049] In some embodiments, the outer wall of the injection tube 1 is provided with scales.

[0050] This embodiment makes it easy to observe the depth of the injection tube 1 inserted into the ground, so as to accurately control the fertilization depth.

[0051] In some embodiments, a line formed by connecting a plurality of fertilization holes 9 in sequence is a spiral line, the spiral line is arranged close to the spiral protrusion 8, and the overall height of the spiral line is higher than the height of the spiral protrusion 8.

[0052] This embodiment can reduce the probability of soil blocking the fertilization hole 9. Specifically, when drilling downward, the spiral protrusion 8 serves to shield the fertilization hole 9 to prevent the soil from being pressed into the fertilization hole 9 during the downward movement. This greatly reduces the probability of the fertilization hole 9 being blocked. In addition, due to the shielding of the spiral protrusion 8, even if some soil still blocks the fertilization hole 9, the degree of blockage must be very light. At this time, as long as the piston 6 moves downward to apply a certain pressure to the fertilizer liquid, the fertilization hole 9 can be flushed open.

[0053] In other words, if the outer wall of the injection tube 1 is not provided with spiral protrusions 8, and only the fertilization holes 9 are provided on the smooth surface, during the downward drilling process, since the soil before drilling is relatively compact and its pressure is relatively large, after the injection tube 1 enters the soil, the soil with relatively large pressure will be directly pressed into the fertilization hole 9, and the degree of blockage will be relatively serious. At this time, it is necessary to apply great pressure to the fertilizer liquid to flush the fertilization hole 9.

[0054] Of course, in some areas with relatively soft soil, the spiral protrusion 8 may not be provided, and the injection tube 1 with a smooth cylindrical surface can be directly used for drilling injection.

[0055] In some embodiments, the injection tube 1 is rotatably arranged on the handheld frame 4 through a bearing. Specifically, the outer ring of the bearing is fixedly connected to the handheld frame 4, and the inner ring is fixedly connected to the injection tube 1. In addition, considering that the handheld frame 4 needs to be pressed down during fertilization, there may be axial force between the handheld frame 4 and the injection tube 1. Therefore, in some embodiments, a thrust bearing 13 can be used to support the injection tube 1. Specifically, a flange ring 14 needs to be fixedly sleeved on the outside of the injection tube 1. The thrust bearing 13 is arranged above the flange ring 14 and sleeved on the outside of the injection tube 1. The moving ring 11 of the thrust bearing 13 is located below the fixed ring 12. The moving ring 11 is fixedly connected to the flange ring 14 and the injection tube 1, and the fixed ring 12 is fixedly connected to the handheld frame 4.

[0056] In some embodiments, the top of the injection tube 1 is expanded to form a bell mouth 10 to facilitate the piston 6 to be inserted into the injection tube 1 and to pour the fertilizer liquid into the injection tube 1 .

[0057] The present invention also provides an injection fertilization method, which uses the above handheld injection fertilization device to perform injection fertilization; comprising:

[0058] Step 1: Aim the drill bit 3 at the ground to be fertilized;

[0059] Step 2: Start the motor 5, and while the syringe 1 rotates, manually press down the hand-held frame 4, and the hand-held frame 4 drives the syringe 1 and the drill bit 3 to drill downwards;

[0060] Step 3: After the drilling is in place, stop pressing down the handheld frame 4 and turn off the motor 5;

[0061] Step 4: pour fertilizer liquid into the injection tube 1;

[0062] Step 5: Install the piston 6 and the piston rod 7 into the injection tube 1, and manually press the piston rod 7 to drive the piston 6 to apply the liquid in the injection tube 1 to the soil through the fertilization hole 9.

[0063] This embodiment has all the advantages of the above embodiments, which will not be described in detail here.

[0064] In some embodiments, the motor 5 has forward and reverse functions; in step two, the motor 5 is started and the injection tube 1 is controlled to rotate forward; it also includes step six: after fertilization is completed, the motor 5 is started and the injection tube 1 is controlled to reverse, and at the same time, the handheld frame 4 is lifted, and the handheld frame 4 drives the injection tube 1 and the drill bit 3 to move upward.

[0065] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
