[0009] Preferably, a groove is provided at the inner bottom end of the mounting shell, a mounting hole penetrating the mounting shell is provided at the groove, and the bottom end of the screw passes through the mounting hole of the mounting shell and is installed on the mounting shell.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The utility model enables a worker to step on a pull rod, so that the pull rod drives a gun rod to move downward and extend from a fertilizer discharge hole of a pipe body to perform a drilling work on the soil. At the same time, the pipe body drives a push plate to be inserted into the soil. After the fertilizer falls into the soil, the gun rod is rotated to cause the pull rod to drive the pipe body to rotate, so that the pipe body drives a plurality of push plates to rotate, and the push plates drive soil to move into the holes opened by the gun rod, so as to cover the holes with soil.

[0017] In order to make the technical means, creative features, objectives and effects of the utility model easy to understand, the utility model is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0018] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings.

[0019] Example 1

[0020] like Figure 1-4 As shown, a plant root fertilizer applicator includes a tube body 1, a pull rod 2 is slidably installed on the outer side of the tube body 1, a gun rod 3 extending to the inner side of the tube body 1 is inserted at the top end of the pull rod 2, a mounting shell 4 is provided at the bottom end of the tube body 1, a plurality of push plates 5 are inserted into the inner side of the mounting shell 4, and a screw 6 inserted into the mounting shell 4 and the tube body 1 is provided at the bottom end of the mounting shell 4 and located between the plurality of push plates 5.

[0021] A fertilizer discharge hole is provided at the bottom end of the tube body 1, and a plurality of push plates 5 are arranged at equal angles according to the fertilizer discharge hole of the tube body 1. It should be noted that one end of the push plate 5 is arranged close to the fertilizer discharge hole of the tube body 1, and the plurality of push plates 5 are placed in a windmill shape, and the plurality of push plates 5 are all placed at an inclination angle of fifteen to sixty degrees, so that when the push plate 5 rotates according to the center of the fertilizer discharge hole of the tube body 1, the soil at the edge of the fertilizer discharge hole of the tube body 1 is moved into the hole to seal the hole.

[0022] A thread is provided on the outside of the bottom end of the tube body 1, and the top of the mounting shell 4 is wrapped around the outside of the bottom end of the tube body 1. A thread groove is provided on the inside of the top end of the mounting shell 4. The thread of the tube body 1 is adapted to the thread groove of the mounting shell 4, and the installation of the push plate 5 is more convenient through the threaded connection.

[0023] The shape of the screw 6 is T-shaped, wherein a groove is provided at the inner bottom end of the mounting shell 4, and a mounting hole penetrating the mounting shell 4 is provided at the groove. The bottom end of the screw 6 passes through the mounting hole of the mounting shell 4 and is installed on the mounting shell 4. The top end of the screw 6 is located on the inner side of the groove of the mounting shell 4. When the mounting shell 4 is separated from the tube body 1, the push plate 5 can be disassembled and assembled.

[0024] Working principle:

[0025] When in use, the tube body 1 is connected to the fertilizer barrel, and the staff holds the top of the gun rod 3 to drive the tube body 1 to move, so that the tube body 1 moves to the fertilization position, and the staff steps on the pull rod 2 to make the pull rod 2 slide on the outside of the tube body 1, and drives the gun rod 3 downward during the sliding process, so that the gun rod 3 extends out through the fertilizer discharge hole of the tube body 1 to punch holes in the soil. At the same time, the tube body 1 drives the push plate 5 to be inserted into the soil, and after the fertilizer falls into the soil, the gun rod 3 is rotated so that the gun rod 3 drives the tube body 1 to rotate through the pull rod 2, so that the tube body 1 drives multiple push plates 5 to rotate through the mounting shell 4, so that the push plates 5 drive the soil to move into the holes opened by the gun rod 3, and the holes are covered with soil, making the application of fertilizer more convenient.
