[0048] See also Figure 1 , Figure 2 , Figure 7 and Figure 8In an example of the plow blade assembly 300 of the utility model, the box 500 includes a first chamber 501 and a second chamber 502; one of the first chamber 501 and the second chamber 502 is configured to accommodate the second battery 420. The first chamber 501 and the second chamber 502 can be arranged along the length direction of the box 500, or along the width direction of the box 500; the area size and specific shape of the first chamber 501 and the second chamber 502 are not limited. In this embodiment, the first chamber 501 and the second chamber 502 are arranged along the width direction of the box 500 (such as Figure 2 The first chamber 501 is arranged in a direction of the Y-axis (as shown in the middle Y-axis direction), and the first chamber 501 is located on the side close to the walking wheel 111. The first chamber 501 is configured to accommodate the second battery 420, and the second chamber 502 is configured to accommodate the counterweight assembly 910. In other embodiments, the second chamber 502 may be configured to accommodate the second battery 420, and the first chamber 501 may be configured to accommodate the counterweight assembly 910. By providing the first chamber 501 and the second chamber 502, the second battery 420 and the counterweight assembly 910 can be provided separately, which can reduce the mutual collision between the second battery 420 and the counterweight assembly 910, thereby reducing the damage caused to the second battery 420 by the counterweight assembly 910, and at the same time, it is also convenient to take and put the counterweight assembly 910 and the second battery 420 separately.

[0049] In another example of the plow blade assembly 300 of the present invention, the first chamber 501 and the second chamber 502 may be configured to accommodate the second battery 420. In this way, the box 500 can be used as a storage room for storing and transporting the second battery 420, and can also take into account the counterweight function, without the need to set up other counterweight assemblies 910.

[0050] In an example of the plow blade assembly 300 of the utility model, the second battery 420 is arranged in at least one of the first chamber 501 and the second chamber 502, and has a first state of being electrically connected to the first battery 410 and a second state of being electrically connected and disconnected from the power source 400. Specifically, the second battery 420 is arranged in the first chamber 501, and the electrical connection method between the second battery 420 and the first battery 410 is not limited. For example, the first chamber 501 may be provided with a wiring terminal electrically connected to the first battery 410. After the second battery 420 is placed in the first chamber 501, it can be electrically connected to the wiring terminal, thereby converting to the first state of being electrically connected to the first battery 410; when the second battery 420 is taken out of the first chamber 501, that is, the second battery 420 is disconnected from the wiring terminal, and converted to the second state of being electrically connected and disconnected from the first battery 410. Alternatively, when the second battery 420 is placed in the first chamber 501, it is electrically connected to the first battery 410 through a connecting wire, that is, when the two ends of the connecting wire are plugged and connected to the second battery 420 and the first battery 410 respectively, the second battery 420 is converted into a first state electrically connected to the first battery 410; the second battery 420 remains stationary, and the electrical connection between the connecting wire and the second battery 420 is disconnected, and the second battery 420 is converted into a second state electrically disconnected from the first battery 410. Only the first state and the second state of the second battery 420 can be realized, and the present application does not limit the electrical connection method between the second battery 420 and the first battery 410. In this embodiment, by setting the first state and the second state of the second battery 420, the disconnection and connection settings between the second battery 420 and the first battery 410 can be realized, so that the electrical connection of the second battery 420 can be better controlled.

[0051] In an example of the rotary tiller 1000 of the present invention, the second battery 420 is contained in the first chamber 501, and the counterweight assembly 910 is contained in the first chamber 501. When the second battery 420 is in the first state, the second battery 420 is electrically connected to the first battery 410, and the first battery 410 is configured to provide power to the walking mechanism 110, so that the second battery 420 provides the running power for the walking mechanism 110. When the second battery 420 is in the second state, the second battery 420 is electrically disconnected from the first battery 410, and the second battery 420 is always contained in the first chamber 501, at which time the second battery 420 and the counterweight assembly 910 adjust the center of gravity of the rotary tiller 1000 together. In other embodiments, the first battery 410 may also be configured to provide power to the tiller assembly 300, so that the second battery 420 provides the running power for the operation of the tiller assembly 300.

[0052] In an example of the rotary tiller 1000 of the utility model, the second battery 420 is accommodated in the first chamber 501, and an input interface is also provided in the first chamber 501, and the second battery 420 is plug-connected with the input interface; the input interface can be a wiring terminal or a socket structure, as long as it can form a stable and reliable plug-in connection relationship with the second battery 420. The box 500 is also provided with an output interface electrically connected to the input interface, and the output interface can be provided on the wall of the first chamber 501 or on the wall of the second chamber 502, and the output interface faces the outside of the box 500. The output interface is electrically connected to the first battery 410 through a first connecting line located outside the box 500, thereby realizing the electrical connection between the second battery 420 and the first battery 410.
