Of the continuously variable transmission 73 via a pair of bevel gears 76, and a speed change output shaft 77 via a pair of bevel gears 76. Each of the feed shafts 64 is connected and interlocked with a pair of bevel gears 78. The feed input shaft 81 is connected to and linked to a left-right feed drive shaft 79 via a pair of bevel gears 80, and the speed change output shaft 77 and the feed input shaft 81 are connected by a universal joint shaft 82. Te, fertilization machine 3 at the output from the engine
6 and adjusts the amount of fertilizer to be fed from the feeding case 38 by the shift operation of the continuously variable transmission 73.

Next, the lid 90 of the fertilizer hopper 37, which is a component of the fertilizer 36 and stores granules to be sprayed by the fertilizer 36, will be described. The fertilizer application hopper 37 of the fertilizer applicator 36 has a slide-type lid 90. As shown in FIG. 5 and FIG. 7, the lid 90 is provided with slide mechanisms 91, 91 of a front-rear slide type, which are substantially symmetrically arranged on both left and right sides of the fertilizer hopper 37, and is provided around the upper surface or a part thereof. It is a plate-shaped member having ribs (standing walls) 90a. Since the lid 90 is of a sliding type, even if a spare seedling or a fertilizer bag is placed on the upper surface of the lid 90, the lid 90 can be opened and closed without removing these placed objects. . Furthermore, when supplying fertilizer to the fertilizer application hopper 37, the lid can be safely and efficiently supplied without the lid becoming unstable due to wind or the like and closing as in the case of the conventional rotary lid. it can. Further, the ribs 90a provided around the upper surface of the lid 90 improve the rigidity of the lid 90. Further, even if the mounted article runs on the lid 90, the mounted article drops. Preventing.

As shown in FIG. 8, the slide mechanism 91 is integrally formed with a ball bearing 92, a slide rail 93 and a lid 90 supported by convex portions 37a provided on the upper left and right sides of the main body of the fertilizer hopper 37. Lid 9 formed
It is composed of a rotating part 90b that protrudes downward before and after zero. The rotating portion 90b of the lid 90 is rotatably supported on a slide rail 93 by a pin 94. Therefore,
The lid 90 rotates about the pin 94 as a rotation center. The slide rail 93 is formed in a substantially U-shape when viewed from the rear, and a ball bearing 9 is provided between upper and lower members.
2 is pinched. That is, the slide rail 93 and the lid 9
0 slides back and forth on the ball bearing 92 integrally.

Then, as shown in FIGS. 9 and 10, the slide rail 93 slides on the ball bearing 92,
When the cover 90 is pulled out to the maximum, the cover 90
Is configured to rotate upward about the above-described pin 94 provided at the rear portion of the side surface of the lid 90. By configuring the slide mechanism 91 as described above, when the fertilizer is supplied to the fertilizer application hopper 37, the fertilizer bag can be placed on the lid body 90 pulled out forward to supply the fertilizer. It is not necessary to keep the fertilizer bag, and the fertilizer can be supplied easily. Further, the lid body 90 pulled out forward plays a role as a cover in front of the fertilizer application hopper 37, and granules such as fertilizer transfer the airframe 1 and the seat 13
To prevent it from falling.

Then, the lid 90 is rotated so as to have a downward slope toward the fertilizer hopper 37. In this embodiment, the ribs 90a on the upper surface of the lid 90 are not all around, but when the slope is provided, the ribs 90a move downward. Since the lid 90 is provided on three sides excluding the sides, the lid 90 is pulled out to the maximum, and when the lid 90 is rotated, the granules falling on the upper surface of the lid 90 are applied to the fertilizer hopper 37.
It can slide down into the garbage without wasting granules.

The cover 90 of the fertilizer hopper 37 described above.
Is a type that is provided in the mid-mount type fertilizer applicator 36, so that it is pulled out forward.For example, in a rear-mount type fertilizer applicator disposed above the planting section at the rear of the rice transplanter, The lid of the fertilizer hopper may be pulled out rearward.

Further, the slide rail 93 of the slide mechanism and the lid 90 may be integrally formed, or the slide mechanism may be formed in a fertilizer hopper. FIG.
As shown in FIG. 1, an L-shaped convex portion formed integrally with the lid 90 is formed as a slide rail 90c, while a ball bearing 92 is provided on the left and right inner side surfaces of the main body of the fertilizer hopper 37. And the slide rail 90c sandwiches the ball bearing 92. Therefore, the lid 9
A slide mechanism 91a in which the ball bearing 92 slides on a slide rail 90c integrally formed with the slide rail 91c. As described above, the lid 90 and the slide rail 90
By integrally configuring c, the number of constituent members of the slide mechanism 91a is reduced, the cost is reduced, and assembly and maintenance are simplified.

[0027]

The present invention is configured as described above.
The following effects are obtained.

That is, according to a first aspect of the present invention, there is provided a fertilizer applicator provided with a fertilizer application hopper and a feeding device disposed below the fertilizer application hopper, wherein a lid covering an upper portion of the fertilizer application hopper is slid in the longitudinal direction of the machine. Since it is configured to be movable and can be opened and closed, when replenishing fertilizer to the fertilizer hopper, the lid becomes unstable due to wind etc. like a conventional rotary lid and it does not close when it is not intended The fertilizer can be supplied safely and efficiently.

According to a second aspect of the present invention, the lid is configured to be rotatable upward with the front or rear as a fulcrum, so that when the fertilizer is supplied to the fertilizer application hopper, the lid is slid and then the lid is slid. When the is turned upward to open, the opening of the fertilizer application hopper can be widely used, so that fertilizer can be easily put in.

According to a third aspect of the present invention, the upright wall is provided around the upper surface of the lid, so that the rigidity of the lid is improved, and the object placed on the upper surface of the lid is stabilized, and Even so, the object does not fall.
