[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0022] like Figure 1-Figure 5As shown, in this embodiment, a fertilizer box structure of a backpack electric fertilizer spreader includes a box body 1 and a battery 2. A battery compartment 11 for accommodating the battery 2 is provided at the bottom of the box body 1. The battery compartment 11 includes a battery compartment 1 111 and a battery compartment 2 112, which are larger and smaller in space. The battery compartment 1 111 and the battery compartment 2 112 are partially or completely overlapped and connected. A socket 12 is provided on the box body 1, and the socket 12 is electrically connected to the battery 2 through an electric wire.

[0023] In actual application, the battery compartment 11 is arranged at the bottom of the box body 1 to avoid conflict with the fertilizer loading, thereby improving the space utilization of the fertilizer box. First, the box body 1 is inverted so that the battery compartment 11 is exposed to the field of vision, and a battery 2 of appropriate capacity is selected according to demand. Then, the positive and negative poles on the battery 2 are electrically connected to the socket 12 through wires, and the battery 2 is properly placed by selecting a matching battery compartment 111 or a battery compartment 2 112 according to the size of the battery 2. Finally, the motor on the fertilization execution component is electrically connected to the socket 12, and the electrical energy on the battery 2 is converted into mechanical energy to drive the centrifugal disk or impeller to rotate to spread the fertilizer.

[0024] Optional, such as Figure 3-Figure 5 As shown, the battery compartment 1 111 and the battery compartment 2 112 are both rectangular, and the battery compartment 11 is cross-shaped, T-shaped, or L-shaped. The above are three implementation schemes in which the battery compartment 1 111 and the battery compartment 2 112 partially overlap and are connected. According to the size of the battery 2, one of the battery compartment 1 111 and the battery compartment 2 112 is selected for installation.

[0025] Furthermore, it also includes a compartment cover 4. The opening of the battery compartment 11 is located on the bottom surface of the box body 1. The compartment cover 4 is sealed on the opening, which makes space utilization more concealed and ensures the safety of the battery 2.

[0026] The compartment cover 4 is snap-connected to the bottom surface of the box body 1 and is detachably fixed to the bottom surface of the box body 1 via fasteners.

[0027] When installing the bin cover 4, first snap it onto the bottom surface of the box body 1 to play a role in positioning and preliminary fixing, and then completely fix it to the bottom surface of the box body 1 through fasteners; when removing the bin cover 4, first detach the fasteners from the bottom surface of the box body 1. At this time, the bin cover 4 is in a snap-on state on the bottom surface of the box body 1 and is not separated from the bottom surface of the box body 1, which facilitates the installation and removal of the bin cover 4 and prevents the bin cover 4 from falling accidentally. The bin cover 4 is used to support and fix the battery 2 to prevent it from falling.

[0028] Optional, such as Figure 6As shown, the battery compartment 1 111 and the battery compartment 2 112 are both rectangular, the length and width of the battery compartment 1 111 are larger than the battery compartment 2 112, and a filling block 3 is detachably fixed in the battery compartment 1 111, and the filling block 3 and the inner wall of the battery compartment 1 111 enclose the battery compartment 2 112.

[0029] When a battery 2 with a small capacity is selected, the battery is placed in the second battery compartment 112, the filling block 3 is fixed to the first battery compartment 111 and enclosed with the inner wall of the first battery compartment 111 to form the second battery compartment 112, the battery 2 is electrically connected to the socket 12 and placed in the second battery compartment 112; when a battery 2 with a large capacity is selected, the filling block 3 is removed from the first battery compartment 111, the battery 2 is placed in the first battery compartment 111 and electrically connected to the socket 12.

[0030] Furthermore, the filling block 3 is L-shaped, and the filling block 3 can be adapted and fitted with the side wall of the battery compartment 111, so that the space occupied by the battery compartment 11 is smaller.

[0031] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
