Problems solved by technology

[0005] However, due to the shape of the lugs of the auxiliary wheels, there is a problem that the lugs protrude into the cultivated layer of the farmland, and soil is entrained in the lugs, thereby reducing the wet field passing ability of the driving body.

Embodiment Construction

[0025] Hereinafter, the specific embodiment of this invention is demonstrated based on the drawing applied to the riding-type rice transplanter 1 (henceforth abbreviated as the rice transplanter 1) of an eight-row transplanting type. It should be noted that, in the following description, the left side when facing the traveling direction of the traveling body 2 is simply referred to as the left side, and the right side when facing the traveling direction is also simply referred to as the right side.

[0026] First, refer to Figure 1 ~ Figure 4 The outline|summary of the rice transplanter 1 is demonstrated. The rice transplanter 1 of embodiment is equipped with the traveling body 2 supported by the front wheel 3 of a pair of right and left which is a traveling wheel, and the rear wheel 4 of a pair of left and right similarly. An engine 5 is mounted on the front portion of the traveling body 2 . It is configured to drive the front wheels 3 and the rear wheels 4 by transmitting...

Abstract

This working vehicle is provided with: a traveling wheel 4 for supporting a traveling machine body; and a cage wheel 100 removably mounted to the traveling wheel 4. The cage wheel 100 is provided withan annular rim 102 and a plurality of cage wheel lugs 105 provided to the rim 102 at appropriate intervals in the circumferential direction of the rim 102. The cage wheel lugs 105 are tilted in sideview such that the outer peripheral end 105a side is located further on the upstream side in the rotational direction during the forward movement of the traveling machine body than the inner peripheral end 105c side. The outer peripheral ends 105a of the cage wheel lugs 105 are bent toward the center of rotation of the rim 102.

Description

technical field [0001] The present invention relates to a work vehicle mainly used for agricultural work, such as a riding rice transplanter for agricultural work, for example. Background technique [0002] In some recent riding-type rice transplanters, wheels are additionally arranged in order to improve running performance in farmland. For example, in the riding-type rice transplanter described in Patent Document 1, auxiliary wheels that rotate integrally with the rear wheels are provided on the left and right inner sides or both sides of the rear wheels to improve the passability of the traveling body in wet fields.
