Problems solved by technology

[0005] However, the above-mentioned rocking cylinder is configured to be able to move as it expands and contracts at a position directly above the lifting cylinder arranged in the center of the machine body. Therefore, due to the overlapping of the two cylinders up and down, there is no possibility of reducing the height dimension of the vehicle height adjusting device. room, become an obstacle to the compactness of the body

Embodiment Construction

[0022] Hereinafter, embodiments specifically configured based on the above-mentioned technical idea will be described with reference to the drawings.

[0023] like figure 1 , figure 2 As shown, the vehicle height adjustment part of the transplant machine is composed of the following parts as the main part: the lifting cylinder 10, which is arranged at the center of the body width; ; left and right equal-length balance fulcrums 51a, which constitute the connecting rod 3b; and the swing cylinder 14, which is connected in a telescopic manner between the lift adjusting rod 3a and the connecting arm 51b on either side (the left side in the illustration) in a telescopic manner.

[0024] The left and right lift adjustment levers 3a, 3a are configured to be able to rotate the left and right driving transmission boxes 9, 9 around the transmission shaft extending left and right from the speed change transmission part 4, thereby respectively adjusting the rear wheels 3, 9 as the left ...

Abstract

The invention provides a transplanter which can inhibit height of a vehicle height adjusting apparatus having a lift cylinder and an oscillating cylinder so as to achieve compactness of a machine body. A piston rod (10a) of the lift cylinder (10) supports a connecting lever (3b). The two ends of the connecting lever are respectively provided with a left and a right connecting arm (51b, 51b). A left and a right lift regulating lever (3a, 3b) which regulates the heights of a left and a right support wheel (3, 3) are linked to the left and the right connecting arm (51b, 5b). The connecting lever (3b) is provided with a balancing fulcrum shaft (51a) which is supported on the piston rod (10a) in a rotary manner. The left and the right connecting arm (51b, 51b) are configured to offset opposite to each other with a rotary axis of the balancing fulcrum shaft (51a) as a benchamark. The oscillating cylinder (14) which enables the balancing fulcrum shaft (51a) to rotate is linked between the left or the right lift regulating lever (3a) and the connecting arm (51b).

Description

technical field [0001] The present invention relates to a transplanter having a vehicle height adjusting device for separately adjusting the vehicle height of left and right support wheels via left and right lift adjustment levers. Background technique [0002] The vehicle height regulating device of the seedling planting machine described in the prior art document 1 has the left and right lift adjustment levers that separately adjust the support height to the left and right support wheels, and has a lift cylinder and a lift cylinder that operates the two lift adjustment levers in the same direction in the center of the body. By operating the swing cylinders of the two lift adjustment levers in opposite directions, it is possible to adjust the height of the vehicle and adjust the inclination of the left and right ( figure 1 , image 3 ). [0003] prior art literature [0004] Patent Document 1: Japanese Patent Application Laid-Open No. 09-000022 [0005] However, the abo...
