Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a drive mechanism of a multi-seeding device equipped with a ridge molding device and sowing and fertilizing fertilizers, seeds, chemicals and the like.

(B) Conventional Technology Conventionally, a device for sowing while forming a ridge has been known. For example, Japanese Utility Model Publication No. 57-53121 and Japanese Utility Model Publication
56-93121, Japanese Utility Model Publication No. 54-36003, Japanese Patent Laid-Open No. 53
-69114, Japanese Patent Laid-Open No. 50-134810, and Japanese Utility Model 38-
28422 and Jikho 57-3363.

The technique described in Japanese Patent No. 9 is publicly known.

(C) Problems to be solved by the invention In the conventional configuration, since the vertical movement of the gauge wheel is the vertical movement due to the oblique rotation of the chain case, there is a part of the multi-device in the front and rear. In this case, it was necessary to move the multi-device further rearward in order to obtain the swing range of the gauge wheel. Further, since the weight of the gauge wheel changes depending on the rotation angle of the chain case, it is necessary to urge the urging spring.

In the present invention, in order to prevent the gauge wheel from swinging in the front-rear direction, the chain case is configured to move up and down, and the gauge wheel is also swingable up and down. It is configured so that it does not become too long.
In addition, the weight of the chain case is configured to be related to the gauge wheel from directly above.

(D) Means for Solving the Problems The present invention is configured as follows in order to solve such problems.

In the configuration in which the gauge wheel 23 is arranged on the side of the ridge molding device constituted by the side molding plate 21 and the pressure plate 37, the front end of the swing frame 26 is pivotally supported on the frame 22 of the ridge molding device and the rear end is rocked. The gauge wheel 23 is pivotally supported on the rear part of the swing frame 26, and the rotation shaft 28 of the gauge wheel 23 serves as a shaft below the lower chain case 24 arranged substantially vertically. The upper counter shaft 70 of 24 is the lower shaft of the upper chain case 25, the lower chain case 24 and the upper chain case 25 are bendable around the counter shaft 70, and the upper shaft of the upper chain case 25 is , Feeding device 12
The lower chain case 24 is configured to move up and down substantially vertically when the gauge wheel 23 moves up and down together with the swing frame 26 due to the unevenness of the soil surface.

(E) Action of the device With such a structure, when working on a rough field or a slope, the gauge wheel 23 should swing up and down around the pivot pin 54 as shown in FIG. With the swing, the chain cases 24, 25 can also swing up and down to follow the field scene, and since the gauge wheel 23 and the lower chain case 24 do not swing back and forth, It is possible to place multiple devices in front and back.

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

First, since the lower chain case 24 moves vertically up and down substantially above the gauge wheel 23, the weight of the lower chain case 24 is always related to the gauge wheel 23 regardless of the rotation position of the gauge wheel 23. The gauge wheel 23 is grounded on the soil surface with a stable grounding pressure without separately providing a grounding biasing spring from above. As a result, stable driven rotation can be obtained.

Second, the gauge wheel 23 moves up and down on the side part of the ridge molding machine,
Moreover, since the lower chain case 24 also vertically moves vertically on the side of the ridge molding machine, the gauge wheel 23 moves up and down in parallel with the vertical movement.
Since the 23 and the lower chain case 24 do not swing back and forth, it is possible to place the ridge former and the multi-apparatus close to each other, and it is possible to shorten the total length of the multi-seeding apparatus. .
