Description

Working vehicle Technical Field The present invention relates to a work vehicle that automatically travels using a vehicle position calculated based on a signal from a positioning unit. Background As a work vehicle including a positioning unit, for example, a rice transplanter described in patent document 1 is known. In the rice transplanter described in patent document 1, a positioning unit having a satellite positioning module for receiving radio waves emitted from satellites of a global navigation satellite system (GNSS: global Navigation SATELLITE SYSTEM) is mounted on a mounting table fixed to an upper surface of a cross member extending in a lateral width direction of a vehicle body of a preliminary seedling support frame. The support portion extends downward from the mounting table, and a voice alarm generator is supported in the box portion formed in the lower portion of the support member. Prior art literature Patent literature Patent document 1 Japanese patent laid-open No. 2021-108621 (JP 2021-108621A) Disclosure of Invention Problems to be solved by the invention When the position of the host vehicle is calculated using radio wave signals from satellites of the GNSS, RTK-GNSS positioning (real-time dynamic GNSS) is used to improve the position accuracy. In the RTK-GNSS positioning, a base station is provided at a known coordinate position near a work site (field), and data communication is performed between the base station and a positioning unit. The operation of setting the base station in an accurate coordinate position places a burden on the farming work under automatic travel. In recent years, in order to reduce such a burden, a VRS (virtual reference station) system (network type RTK-GNSS positioning) is adopted instead of the RTK-GNSS positioning. In this VRS scheme, a base station is not required, but a VRS communication means (virtual reference point data receiving means) for exchanging data with the GNSS correction data transfer service is required. The VRS communication unit needs to be disposed in a place where radio waves are not interfered by the constituent members of the work vehicle, as in the positioning unit. In view of the above-described circumstances, an object of the present invention is to provide a work vehicle in which devices such as a VRS communication unit can be disposed in a place where radio wave conditions are good, as in a positioning unit. Solution for solving the problem The work vehicle capable of automatically traveling includes a support frame that is provided upright on a vehicle body, a support bracket that is fixed to a cross member of the support frame so as to straddle the cross member of the support frame, a positioning unit that is mounted on an upper portion of the support bracket, and a container that has a storage chamber that is mounted on a lower portion of the support bracket, wherein the container is configured from a fixed structure that is mounted on the support bracket and a switching structure that can be switched between a closed state and an open state. According to this configuration, the receiver that can receive the equipment such as the communication unit is mounted together with the positioning unit on the support frame that is provided upright on the vehicle body via the common support bracket. The positioning unit is mounted in a place where the radio wave condition is good (a place where the reception sensitivity is good), and therefore the radio wave condition inside the container mounted near the positioning unit is also basically good. Further, since the receiver is located below the positioning unit, the receiver is less likely to interfere with the radio wave conditions of the positioning unit. Further, since the storage container is constituted by the switching structure capable of switching between the closed state and the open state with respect to the fixed structure mounted on the support bracket, the equipment stored in the storage container is easily contacted by setting the switching structure to the open state. If the switching structure that can switch between the closed state and the open state with respect to the fixed structure can maintain the fixed posture in the open state without being separated from the fixed structure, it is convenient to contact the device housed in the housing. In the present invention, therefore, it is proposed that the switching structure be provided as a displacement structure provided on the fixed structure so as to be displaceable between a closed position and an open position. Further, as a preferred displacement structure, a swing structure provided on the fixed structure so as to be capable of swinging between the closed posture and the open posture is proposed. The swing structure has an advantage that a large opening can be formed in an open posture, although it is simply displaced. Of course, as other displacement structures, up-and-down sliding structures, horizontal sliding
