Problems solved by technology

[0008] Then, if the traveling body suddenly starts or accelerates rapidly, then because the front portion of the traveling body floats, the rice transplanting device at the rear portion descends, causing the problem that the planting depth of the seedlings relative to the field surface is too deep compared with the specified value. In addition, if If the above-mentioned traveling body decelerates or stops abruptly, the traveling body will easily deviate laterally and meander
[0009] In addition, in the structure in which the movement of the shift pedal is transmitted to the travel transmission by the connecting rod as in Patent Document 1, there is also a possibility that the resistance of the shift lever of the travel transmission acts as a resistance to the movement of the shift pedal, which affects the movement of the shift pedal. The problem that a large force is required to step on the pedal, and the problem that the shifting operability and running operation feeling are reduced due to the so-called backlash phenomenon when the shock or load is transmitted to the shift pedal when the shift lever is activated

Embodiment Construction

[0033] Embodiments of the present invention will be described below with reference to the drawings.

[0034] figure 1 and figure 2 In , symbol 1 represents a passenger-type planter. This ride-on type planter 1 is made up of a traveling body 2 and a conventionally known multi-ridge planting type rice transplanting device 3 that can be lifted and mounted on its rear portion. A pair of rear wheels 6 supports the body frame 4 .

[0035] In addition, on the vehicle body frame 4 of the above-mentioned traveling body 2, an engine 7 is mounted, and a travel transmission 8 that transmits power from the engine 7 to the front and rear wheels 5, 6 is mounted. Drive straight in the direction of arrow A with four-wheel drive.

[0036] In addition, on the upper surface of the vehicle body frame 4 of the above-mentioned traveling body 2, an operation operation part 9 equipped with a steering wheel 10 and a seat 11 is provided, and the position on the right side of the above-mentioned ope...

Abstract

A riding - type rice transplanter comprises a traveling frame (2) having traveling wheels (5, 6) driven by an engine (7), a seedling planting device (3) installed at the rear of the traveling frame (2), a traveling transmission (8(14)) for the traveling wheels (5, 6), and a gear shift pedal (12) installed at the operation control part (9) of the traveling frame. The riding - type rice transplanter further comprises an actuator (28) for shift-operating the traveling transmission and a detection means (24) for detecting the depressing operation and the releasing operation of the gear shift pedal (12). The actuator (28) operates the traveling transmission (8(14)) to an increase in speed when the detection device (24) detects the depressing operation of the gear shift pedal, and operates the traveling transmission (8(14)) to a decrease in speed when the detection means detects the releasing operation of the transmission pedal (12).

Description

[0001] This application is a divisional application of an invention patent application named "passenger-type planter", with an international filing date of February 5, 2009, an international application number of PCT / JP2009 / 051982, and a national application number of 200980107746.X. technical field [0002] The present invention relates to a ride-on type planter in which a rice transplanting device is installed on the rear or front of a traveling body. More specifically, it relates to a passenger-type planter whose travel speed is changed by a foot-operated speed change pedal. Background technique [0003] In the case of automobiles such as passenger cars and tractors, the speed of the vehicle is generally changed by adjusting the amount of fuel injection. However, since the engine of the planter not only travels, but also drives the rice transplanting device, the engine's It is not good to change the output too much, so the vehicle speed is changed by controlling the trans...
