Problems solved by technology

[0004] However, there are cases where sun visors and the like are installed to make the working space of the rice transplanter comfortable.
In this case, the measurement unit needs to be positioned higher than the sun visor in the use state due to the characteristic of acquiring the positioning information from the satellite, and it needs to be able to change the use state and the storage state, but this is not done at all in Patent Document 1. such research

[0052] First, the schematic structure of the rice transplanter 1 is demonstrated. figure 1 It is a left side view of the rice transplanter 1 which concerns on this embodiment. In addition, in the following description, the travel body 2 along the direction of travel ( figure 1 The left side in the direction of travel) is simply referred to as the left side, and similarly the right side along the direction of travel is simply referred to as the right side.

[0053] The rice transplanter 1 is equipped with the traveling body 2 , the left and right pair of front wheels 3 and 3 and the left and right pair of rear wheels 4 and 4 supporting the traveling body 2 , and the engine 5 mounted on the front part of the traveling body 2 . The front wheels 3, 3 and the rear wheels 4, 4 are driven by transmitting power from the engine 5 to the rear transmission case 6, so that the traveling body 2 travels forward and backward. The front axle case 7 protrudes to the left and right sides of t...

[0079] Figure 7 It is a left side view of the rice transplanter 1 equipped with the sun visor 40. The sun visor 40 is supported by a first sun visor frame 41 and a second sun visor frame 42 . The first sun visor frame 41 supports the front portion of the sun visor 40 , and the second sun visor frame 42 supports the rear portion of the sun visor 40 . In the second embodiment, the unit frame 35 is rotatably coupled to the intermediate portions of the left and right first sun visor frames 41 . That is, since the positioning unit 36 ​​and the unit frame 35 can be rotated to the front side of the body around the rotation shaft 35a in the left-right direction, they can be changed to a use state located above the upper end of the first sun visor frame 41, and a position lower than the first sun visor frame 41. Since the upper end of the panel frame 41 is stored downward, the positioning unit 36 ​​and the unit frame 35 do not collide with the sun visor 40 .

no. 3 Embodiment approach ＞

[0084] Figure 9 as well as Figure 10 The form in which one preliminary seedling frame 32,32 is respectively provided in the left and right sides of the machine cover 11, and eight preliminary seedling stands 31 are respectively provided in each preliminary seedling frame 32 is shown. The preliminary seedling stand 31 is configured to be rotatable around the preliminary seedling frame 32 as an axis. In this 3rd embodiment, since the space|interval of the preliminary seedling frame 32 on either side is large, and the left-right width of the unit frame 35 is wide, the support member 43 which supports the unit frame 35 is provided. The support member 43 stands upright from the bottom plate on the right side of the cover 11 . By providing the supporting member 43, the unit frame 35 is reinforced, and the vibration-proof effect of the positioning unit 36 ​​is obtained. The arrangement of the support member 43 is not limited to the above-mentioned configuration, and may be arran...

Abstract

A rice transplanter (1) is provided with: a travel body (2); a seedling planting device (21) arranged behind the travel body (2); left and right spare seedling tables (31) on which spare seedling to be supplied to the seedling planting device (21) can be mounted; left and right support frames (34) respectively extending upward from the left and right spare seedling tables (31); a unit frame (35) linked with the left and right support frames (34); and a ranging unit (36) which is supported on the unit frame (35) and acquires position information of the travel body (2). The ranging unit (36) ispivotable toward the front of the body about a left-right pivot axis (35a) and is thereby changeable to a use state of being positioned higher than the upper end of the support frames (34) and a retracted state of being positioned lower than the upper end of the support frames (34).

Description

technical field [0001] The present invention relates to a rice transplanter. Background technique [0002] In the following patent document 1, it is disclosed that the measurement unit capable of changing the state to obtain position information is located above the upper end of the reserve seedling frame, and the measurement unit is positioned higher than the reserve seedling when it is inverted up and down relative to the use state. A rice transplanter in a stored state with the upper end of the frame lower. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2017-112962 [0004] However, in order to make the work space of a rice transplanter comfortable, a sun visor etc. may be mounted. In this case, the measurement unit needs to be positioned higher than the sun visor in the use state due to the characteristic of acquiring the positioning information from the satellite, and it needs to be able to change the use state and the storage state, but this is not done at...
