The Figure 3 The present application provides a crop spraying cart, for the convenience of description, hereinafter referred to as cart 1000. The

[0044] The cart 1000 includes a frame 100, a push handle 200 and a spraying assembly 300. The bottom of the frame 100 is provided with wheels 110, and the frame 100 has an absolute first side 101 and a second side 102 in the front-rear direction. The front side is the direction of travel of the cart 1000, and the rear side is the opposite direction. The push handle 200 is provided with a grip 210, and the push handle 200 is rotatably mounted on the frame 100 and has a first position of the grip 210 at the first side 101 as shown in Figure 1 and a second position at the second side 102 as shown in Figure 2 .

[0045] The spraying assembly 300 is arranged on the frame 100 and comprises liquid delivery pipes 310 extending out of the frame 100 along the left and right sides and provided with liquid outlets, the liquid delivery pipes 310 are provided with joints connected to liquid storage tanks 400, and the liquid in the liquid storage tanks 400 is delivered out through the liquid outlets of the liquid delivery pipes 310. The liquid storage tanks 400 can store liquid such as clean water, chemical fertilizer or pesticide. The number of the liquid delivery pipes 310 can be one or more, and the extension direction of each liquid delivery pipe 310 includes but is not limited to the vertical front-rear direction shown in the figure, and can also be at an angle to the front-rear direction.

[0046] The liquid storage tanks 400 can be mounted on the frame 100 according to the prior art, or according to an embodiment provided in the present application, the liquid storage tanks 400 are arranged at the edge of the field instead of being mounted on the frame 100, and the volume of the frame 100 can be appropriately reduced, especially the size in the front-rear direction, for example, the frame 100 is a frame structure, the length in the front-rear direction is L1, and the length in the left-right direction is L2, L2:L1=5-8, which reduces the weight of the cart and facilitates the pushing operation of the vehicle.
