(Technical significance)

The technical significance of the configuration of the working vehicle is summarized as follows.

The working vehicle having the above-described configuration is configured so that the floor step (4) is provided in the main frame (3), and the working block is provided so as to be capable of running- And left and right fertilization frames 8 and 8 for supporting the left and right fertilization blocks 7 and 7 are formed in the main frame 3 to the left and right Right and left synthetic front frames 3a and 3a for fixing the front sides of the right and left synthetic frames 8 and 8 are provided on the main frame 3 in addition to the protrusions.

In this way, the fertilization blocks 7 and 7 can be arranged on the left and right sides of the main frame 3 by the fertilization frames 8 and 8 on the left and right sides of the base, and the left and right fertilized front frames 3a and 3a, Durability is improved by fixing the right and left fertilization frames 8, 8 to the frame 3, respectively.

By providing the working blocks 7 and 7 on both the right and left sides of the running body, work space is widened, workability is improved, and balance of the running body is also improved.

Next, the transmission shaft includes a first transmission shaft 12 for transmitting a driving force to one of the left and right fertilization blocks 7 and 7 through a specific amount adjusting unit 13 for adjusting a fertilization operation amount, 7 and 7, and the first transmission shaft 12 and the second transmission shaft 14 are constituted by the floor step 4 and the right and left fertilizing blocks 14, (7, 7).

In this way, the fertilizing force is transmitted from the first transmission shaft 12 to the one fertilization block 7 and the second fertilization block 7 through the second transmission shaft 14, And the second transfer shaft 14 is transferred to the floor step 4 and the left and right fertilization blocks 7, 7 So that the floor step 4 and the fertilization blocks 7 and 7 serve as guards of the electric motor system to improve the safety. And does not interfere with the work space on the floor step (4).

The working vehicle is provided with a transmission case 11 for diverting the driving power from the running support portion of the main frame 3 and a main transmission rod 12 for connecting the transmission case 11 and the first transmission shaft 12, Left and right transmission rods 14b and 14b for connecting the second transmission shaft 14 and the left and right fertilization blocks 7 and 7 are provided in the main transmission rod 11a, The rod 14b is configured to be adjustable in length.

The adjustment amount of the left and right fertilization blocks 7 and 7 can be adjusted with the minimum configuration by the adjustment rod which is adjustable in length at three places so that maintenance can be efficiently performed.

The work vehicle is also provided with rear frames 3b and 3b for fixing the rear portions of the right and left fertile frames 8 and 8 to the left and right of the main frame 3 to respectively connect the points 14a And the rear frame 3b are connected to each other at a position intermediate of the point 14a of the second transmission shaft 14 on the same side with respect to the point of the applied amount adjusting section 13, do.

By connecting the fertilizing frame 8,8 and the rear frame 3b at the intermediate position with the point 14a of the second transmission shaft 14 on the same side with respect to the point of the specific amount adjusting section 13, And it is not necessary to provide an extra transmission shaft or length adjusting mechanism, so that the cost can be reduced.

The working vehicle includes left and right blowing ducts 22 and 22 for feeding conveying air from the gas inward position to the left and right fertilization blocks 7 and 7 and left and right exhaust ducts 22 and 22 for discharging the remaining fertilizer to the gas- (23, 23) are provided, and discharge openings (23a, 23a) which can be opened and closed are provided in the left and right discharge ducts (23, 23), respectively.

By thus opening the left and right discharge ports 23a and 23a, the discharging operation of the fertilizer can be performed from the outside of the casing by the ventilation ducts 22 and 22 inside the casing and the ventilation ducts 23 and 23 outside the casing Work efficiency is good.

In addition, by separately discharging the fertilizer, it is not necessary to switch the direction of the duct or the air collecting the remaining fertilizer at the time of discharging the fertilizer. Further, it is unnecessary to use an air direction switching component or the like, which makes it possible to reduce the cost.

The working vehicle is provided with an air chamber 22a communicating with the left and right air blowing ducts 22 and 22 along the trailing edge of the floor step 4 and the left and right curved portions 22b and 22b of the air chamber 22a The left and right exhaust ducts 23 and 23 are respectively supported in the forward and downward directions to form the front ends as the exhaust ports 23a and 23a.

By thus supporting the left and right discharge ducts 23 and 23 downward to the discharge ports 23a and 23a, the residual fertilizer can be easily dropped to its own weight, thereby improving the discharge speed and discharging even a small amount of air. In addition, since the penetration of the storm is prevented, and the fertilizer is not accumulated, the maintenance property is improved.
