[0028] The preferred embodiments of the present application are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that the embodiments are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application. It should be noted that in the description of the present application, the terms "front", "back", "up", "down", "left", "right", "vertical", "horizontal", "inner", "outer" and other terms indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings, which is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. It should also be noted that in the description of the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or the communication between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0029] Referring to the accompanying drawings Figure 1 A fertilizer applicator for planting peony flowers is composed of a sleeve 1, a drill rod 2 and a rotary valve rod 3. The structure and function thereof are described below.

[0030] Referring to the accompanying drawings Figure 2 . The accompanying drawings Figure 2 As can be seen, the sleeve 1 is in the shape of a long tube, and a pair of hand levers 12 is connected to the outer wall of the sleeve 1. The pair of hand levers 12 is located at the upper part of the sleeve 1, and a foot lever 13 is connected to the lower part of the sleeve 1.

[0031] Referring to the accompanying drawings Figure 3 . The accompanying drawings Figure 3 As can be seen, a plurality of ball sockets are provided on the inner wall of the sleeve 1, and a ball 11 is installed in each ball socket. In order to facilitate the injection of lubricating grease into the ball 11, a grease injection hole 14 is provided on the outer wall of the sleeve 1, and the grease injection hole 14 is in communication with the ball socket.

[0032] Referring to the accompanying drawings Figure 1 , the accompanying drawings Figure 4 and the accompanying drawings Figure 5 . The accompanying drawings Figure 1 , the accompanying drawings Figure 4 and the accompanying drawings Figure 5 As can be seen, the drill rod 2 is installed in the sleeve 1, and a semicircular spiral groove 21 with long pitch matching the ball 11 is provided at the middle part of the drill rod 2. In this embodiment, the semicircular spiral groove 21 has two channels, and the two channels of the semicircular spiral groove 21 are symmetrically arranged about the axis of the drill rod 2.

[0033] A drill bit 23 and a pair of fertilizer outlets 24 are provided at the lower end of the drill rod 2. The drill bit 23 is composed of four triangular drill blades, which are evenly distributed along the circumference of the drill rod 2. The pair of fertilizer outlets 24 are located between adjacent drill blades. A fertilizer hopper 22 is provided at the upper end of the drill rod 2, and a connecting hole 25 is provided between the fertilizer hopper 22 and the fertilizer outlets 24.

[0034] See attached document Figure 6 From the appendix Figure 6 It can be seen that because the semi-circular spiral groove 21 has a long pitch and is matched with the ball 11, it has very little friction. Therefore, the thread structure formed by the ball 11 and the semi-circular spiral groove 21 does not have self-locking property. Under its own weight, the drill rod 2 can rotate relative to the sleeve 1 while moving downward relative to the sleeve 1.

[0035] See attached document Figure 1 Appendix Figure 5 and attached Figure 7 From the appendix Figure 1 Appendix Figure 5 and attached Figure 7 As can be seen, the rotary valve stem 3 is installed inside the connecting hole 25. The rotary valve stem 3 consists of a valve body 31 and a rotating rod 32. The valve body 31 is a disc with a pair of half-discs. The valve body 31 cooperates with the fertilizer outlet 24 and is used to open or close the fertilizer outlet 24. The upper end of the rotating rod 32 has a handle that extends upward beyond the fertilizer hopper 22.

[0036] See attached document Figure 8 From the appendix Figure 8 As can be seen, the valve body 31 can rotate. When the disc faces the fertilizer outlet 24, fertilizer can flow out of the fertilizer outlet 24; when the disc faces the fertilizer outlet 24, the fertilizer outlet 24 is closed.

[0037] How to use:

[0038] Before use, pour the fertilizer granules into the fertilizer hopper 22. Since the fertilizer outlet 24 is closed, the fertilizer granules cannot flow out of the fertilizer outlet 24.

[0039] In use, hold the hand lever 12 and apply downward pressure. At this time, the drill bit 23 will touch the ground and begin to rotate. As the sleeve 1 descends, you can step on the foot pedal 13 to take over the pressure from the hand lever 12. As the drill bit 23 continues to rotate, a pit is drilled at the base of the peony. Then, turn the handle of the rotary valve 3 90° to open the fertilizer outlet 24 and allow the fertilizer granules to enter the pit. Finally, fill the pit with soil to cover the fertilizer granules.

[0040] As can be seen from the above, workers only need to press down the hand lever 12 and the foot lever 13 to dig a hole, and then turn the handle to complete the fertilization. The operation is time-saving and labor-saving, and the fertilization efficiency is high.

[0041] The portions not detailed are prior art. Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
