Description

[Detailed description of the device] (a) Field of industrial application The present invention relates to a deep-layer fertilizer applicator, which is mounted instead of the planting device, in order to perform additional fertilization on the seedlings planted by the rice transplanter. is there.

(B) Conventional Technology Conventionally, the technology related to the deep-layer fertilizer application has been known. For example, it is like the technique described in Japanese Utility Model Laid-Open No. 59-29114.

(C) Problems to be solved by the invention However, in the above-mentioned conventional technique, although the sled is provided, since the grooving body is plate-shaped and cannot rotate,
Paddy field contaminants such as straws and weeds are apt to be applied, and in the prior art, it was impossible to adjust the fertilization depth when performing deep fertilization.

The present invention solves the above-mentioned problems of the conventional technology.

(D) Means for Solving the Problem The present invention has the following configuration in view of such a point.

In the fertilizer applicator in which the fertilizer feeding device 14 is arranged on the fertilizer application frame 13 in alignment with the strips, a support frame 24 is provided below the fertilizer application frame 13 and a sled 30 is provided at the lower end of the support frame 24. Notch 30a configured in

In the deep-layer fertilizer applicator B, a fertilizer application frame 13 is fixedly mounted via a link 11 and a frame 12 from a mounting frame 10 arranged at the rear end of the three-point link type work implement attachment device A, and a feeding device 14 is attached to the fertilizer application frame 13.・ 14 ・ ・ are fixed so that they are located between the threads.

A hopper 15 is placed on the feeding device 14, and a guide hose 16 is connected to the lower end of the feeding device 14.

Further, in order to drive the roll of the feeding device 14, power is transmitted from the rear end of the PTO shaft 7 to a gear box 17 fixed to the central portion of the mounting frame 10 via a universal joint, and the gear box From the output shaft 19 projecting from the rear end of the drive shaft 17 to both sides, the drive shaft 2 is connected via the rotary arm 20, the connecting link 21, and the one-way clutch 22.
3 is rotated, the roll of the feeding device 14 is rotated, and the fertilizer in the hopper 15 is fed.

A support frame 24 is provided so as to project below the fertilization frame 13, and a fertilization section C is provided at the lower end of the support frame 24.
Is installed.

As shown in FIG. 4, the fertilizer application part C includes the groove body 26 and the sled 3
0, a guide cover 32, etc., a pivot shaft 25 is laterally installed at the lower end of the support frame 24, a grooving body 26 is rotatably supported, and a mounting stay 31 erected at the center of the sled 30.
The upper end is fixed to the lower end of the support frame 24.

Further, a support stay 27 is provided at a lower portion of the support frame 24 so as to project rearward, and a guide cover 32 is fixedly provided at a rear end of the support stay 27. The guide cover 32 is formed in a U shape in plan view, Secure the lower end of the hose 16 to the sled 3
It stands on 0.

The sled 30 has a U-shaped plan view and a notch 30 with an open rear.
a is provided, the groove 26 is inserted into the notch 30a, and the guide cover 32 is fixedly provided at the rear part thereof.

The sled 30 is a float 3 as shown in FIG.
It may be configured by 0 '.

Further, the groove body 26 can be vertically adjusted so that the groove depth can be adjusted.

As shown in FIG. 5, the links 34 and 35 are arranged in an X shape, and a pivot shaft 25 is provided at the intersection of the links 34 and 35 to pivotally support the groove 26.

The lower end of the link 34 is pivotally supported by the long hole 36 on the float 30 ', the lower end of the link 35 is pivotally supported by the support 37 on the float 30', and the upper end of the link 34 is connected to the depth adjusting handle 39. Pivot body 4 fixed in the middle of the feed screw 40
1, the upper end of the link 35 is pivotally supported by a pivot body 42 screwed to the feed screw 40, and the groove 26 can be moved up and down by rotating the depth adjusting handle 39.

FIG. 6 shows another embodiment, in which the groove 26 is rotatably supported at the lower end of the support frame 43 protruding downward from the fertilizer frame 13, and occasionally the arm 44 is pivotally supported on the fertilizer frame 13 to make a tip. A support shaft 45 is fixedly mounted on the support shaft 45, a support frame 46 is projected from the support shaft 45, and the sled 30
The depth adjusting handle 47 is interposed between the fertilizing frame 13 and the support shaft 45, and the depth adjusting handle 47 is rotated to change the height of the sled 30 to form a groove. It is configured so that the depth of the body 26 can be changed.

In this case, the depth of the furrowing machine B mounted on the fertilizer application frame 13 can be adjusted at one time.

The groove 26 may have a rectangular cross-sectional shape as shown in FIG. 6, but it may not be possible to make grooves due to foreign matters. Therefore, as shown in FIG. The outer peripheral portion of the body 26 'may have a pointed shape, and as shown in FIG. 8, the groove 26' may have a rhombic cross section so that the groove can be formed. Is also good.

(G) Effect of the Invention With the above-mentioned configuration, the present invention has the following effects.

First, since the rotary disk-shaped grooving body 26 is arranged with respect to the sled 30 arranged at the lower end of the support frame 24, the soil grooving body 26 is exposed to soil contaminants such as straw and weeds. It's gone.

Secondly, since the position of the groove body 26 can be adjusted with respect to the sled 30, it is possible to freely adjust the depth of deep fertilization.

Thirdly, since the fertilizer is sprinkled in the groove formed between the lines in the groove-making body, the fertilizer is efficiently absorbed without burning the fertilizer.
