[0059] When the first fertilizer spreader 3 is in operation, the first latch 321c abuts against the vertical end surface of the first base 11c. When the first fertilizer spreader 3 is in non-operational state, the second caliper 322c abuts against the upper end surface of the first base 11c. In the fourth embodiment, a connecting rod can be added to increase the strength of the device.

[0060] The paddy field work vehicle 100 of the present invention, specifically a rice transplanter, requires a wider rear area behind the driver to improve transplanting efficiency and operator comfort. This increases the overall width of the transplanter. This creates a safety issue during long-distance transport, as the fertilizer spreaders on both sides of the vehicle protrude from the sides.

[0061] In the paddy field work vehicle 100 of the present invention, the first fertilizer spreader 3 and the second fertilizer spreader 4, which are respectively arranged on both sides, can be flipped toward the inside of the rice transplanter, thereby reducing the width of the entire vehicle and facilitating transportation. In other embodiments, the same effect can be achieved by other structures. In addition to derivative designs based on the mechanical structure disclosed in the present invention, other technical solutions can also be adopted, such as providing slide rails along the width direction of the pedals so that the fertilizer spreaders can be translated on the slide rails. Such solutions all fall within the scope of protection of the present invention.

[0062] In other technical solutions, the fertilizer spreader can also be fixed on the fertilizer spreader mounting frame, and the same effect can be achieved by arranging a telescopic device on the fertilizer spreader mounting frame.

[0063] It will be apparent to those skilled in the art that various modifications and variations may be made to the above exemplary embodiments of the present invention without departing from the spirit and scope of the present invention. Therefore, it is intended that the present invention cover modifications and variations of the present invention that fall within the scope of the appended claims and their equivalent technical solutions.
