DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simultaneous sowing machine for cultivating a field where grain culms have been harvested, and for planting seedlings in a portion where the surface layer has been shaved while shaking.

[0002]

2. Description of the Related Art Conventionally, a method of cultivating a field where grain culms have been harvested and scratching the entire plowed layer, a method of planting seedlings in a field after harvesting grain culms in a non-tillage state, and Planting machines that plow only the narrow width of the above-mentioned field and plant seedlings in the plowed portion are already known.

[0003]

Among the above-mentioned known planting methods, the first method requires a great deal of labor to replace the entire cultivated layer, and is kneaded to the deep layer to eliminate voids in the soil. Moreover, after the scraping, the planting operation must be separately performed by the planting device. Further, the second method is that, in the field at the time of planting, there are crawl marks and pits of a combine at the time of harvesting, which lacks uniformity, and because there are many old plants and weeds, remarkable deep planting or shallow planting is performed. Floating seedlings and poor growth occur. Furthermore, in the third method, it was difficult to stand and maintain the planted seedlings because the soil at the cultivated portion of the planting row was not sticky.

[0004]

SUMMARY OF THE INVENTION According to the present invention, a plurality of planting bodies are arranged at a rear portion of a traveling vehicle at a predetermined spacing between the planting lines in a lateral direction, and these planting bodies and a plant immediately before the planting body are arranged. A scraper rotor that is forcibly rotated and driven between the wheels is supported in a horizontal direction, and both side portions of the scraper rotor are protruded outward from the planting positions on both sides by 1/2 or more of the spacing between the planting strips. The present invention solves the above-mentioned problem, and prevents the generation of unscheduled portions in which weeds tend to proliferate at an early stage during the process of planting substitutes.

[0005]

After cultivating the harvested field, it is flooded, and in this state, a plurality of left and right sloping ridges are protruded at a horizontal interval on the peripheral surface. When it is advanced while rotating in a state of being penetrated into the surface layer of the cultivated soil, the inclined ridge stirs and mixes the soil and water while pushing the surface soil to the side at the portion inclined to one side. When the direction of the ridge is changed to the other, the surface soil is extruded to the other and agitated and mixed. The surface layer of the cultivated soil is leveled while well kneading, and the deeper layer than the scraped surface remains plowed, so that many voids can be left, followed by each planting body. Plant multiple rows of seedlings at horizontal intervals. Such surface layer scratching and planting performed immediately after that,
When reciprocating from one side of the field to the other side, the scraping rotor scrapes to the outside from the outer planting position, so the scraping is performed repeatedly on the side every time it reciprocates. As a result, there is no unremoved portion where weeds tend to grow during the planting process.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. A traveling vehicle 1 has a traveling device including front wheels 2, 2 and rear wheels 3, 3, and the power of an engine 4 is transmitted by a transmission case 5 by a transmission device. And a PTO shaft at the rear part of the fuselage. Behind the fuselage, a top link 6 and lower links 7, 7 are provided.
The input device is connected to the PTO shaft via a universal joint 9 and an intermediate shaft so as to be movable up and down. Horizontal shaft 11 in drive shaft case 11 connected to case 10
a plurality of planting transmission cases 12 transmitted through a.
It is constituted by a plurality of planting bodies 14 driven by the planting transmission case 12 and a seedling table 15 which reciprocates in the lateral direction.

[0007] Further, the planting transmission cases 12, 1 at the left and right ends.
The lower part of 2 is connected to a sliding body 16 for eliminating wheel marks, the rear part can be adjusted up and down, and the front part can be moved up and down by a square link. Also, the sliding body 16 is mounted, and the sliding body 16 is connected to a control valve of a hydraulic cylinder for raising and lowering the planting device 8 through a plurality of links, thereby making the planting device 8 constant. The sliding body 16 has both front sides extending outwardly. With such a configuration, it is possible to satisfactorily level the unevenness of the rice field over substantially the entire width from the wheel mark to the middle part, and In addition, the effect of the herbicide can be enhanced at the same time as the occurrence of weeds can be suppressed, and the sensing accuracy when controlling the control valve of the hydraulic cylinder can be improved by extending the front sides of the central slide 16 largely to both sides. Can be improved.

The left and right planting transmission cases 1
To the brackets 18 fixed to the outer surfaces of the brackets 2 and 12, forwardly-moving stays 19 and 19 are rotatably connected, respectively, and the front ends of the stays 19 and 19 are connected to both sides via bearings. The rotatable shaft 20 is rotatably supported, and a rubber (or steel) rotatable rotor 21 is integrally mounted on the rotatable shaft 20. As shown in FIGS. 4 and 5, a large number of lugs (or meandering) ridges 22... Bent in a zigzag shape are provided at intervals in the axial direction. The protruding ridges 22 may be ones intermittently arranged in a bent shape, or ones intermittently arranged ones inclined left and right,
The spacing between the ridges 22 is such that the bent portions of the adjacent ridges 22 wrap by D in the lateral direction as shown in FIG. Furthermore, the length of the substitute rotor 21 is longer than the planting width (planting line interval L × number of planting lines n) in one stroke, and both ends are separated from the outermost planting lines as shown in FIG. L / 2
It protrudes by + α.

In short, when the substitute rotor 21 advances while rotating, the ridges 22...
The action of alternately pressing in the left-right direction is repeatedly performed, and the width of the planting width is increased by adding α to both sides in one stroke. Also, large-diameter disks 21a, 21a are fastened to the ends of the substitute rotor 21 with nuts to prevent the muddy soil from flowing outward. Furthermore,
A bracket 23a fixed to a lower portion of a column 6a to which the rear portion of the top link 6 is connected has a lower portion of the
Since the support plate 23b with a long hole that is provided upright on the gear case 23 that supports the gear is screwed up and down so as to be vertically adjustable, the rotor 21 can be adjusted up and down. Since it protrudes above the shaft 20, there is no need to squeeze it.

Next, the transmission device will be described. The PTO shaft projecting rearward from the transmission case 5 drives the input shaft of the planting device 8 via the intermediate shaft and the extendable universal joint 9, and is attached to the drive shaft 24. The sprocket 24a also distributes power to the input shaft of the speed reducer 26, and when a shift lever 28 provided on the rear side of the driver's seat 27 is operated, the gear is changed to shift the output shaft 30 of the speed reducer 26, and this output is output. The shaft 30 drives an input shaft 33 of the gear case 23 disposed at an intermediate portion of the substitute shaft 20 via a retractable universal joint 31 whose rear portion is supported by a bracket 32. At this time, the rotation direction of the scraping roller 21 is the same as that of the wheels, and the peripheral speed is about 1.2 to 1.5 times the running speed. In a field of easily collapsed soil such as volcanic ash soil, the peripheral speed is low. It is desirable to increase the speed in a hard field such as clay soil. The fertilizer pump 35 disposed below the driver's seat 27 is also driven by the drive shaft 24.

The drive shaft case 11 integrated with the transmission case 10 and the planted transmission cases 12 at both ends are provided outside.
A fertilizer 37 is mounted on the plate 36 integrally fastened thereto so as to be adjustable in height. The fertilizer 37 is mounted on a support shaft 38 and is close to a fertilizer nozzle 40. The fertilizer tank 40 comprises a rotating disk 39 which is inclined forward of the discharge port and has a lower part that penetrates into the mud to form a fertilizing groove.
The fertilizer application pump 35, which sucks in the paste-like fertilizer in 1 through a suction hose 42 and feeds the fertilizer, feeds the hose 43
・ Connected via and indicator.

[0012] Next, a description will be given of the scraping and planting. After harvesting the rice in the previous year, plowing with a rotary tilling device attached to a tractor in the fall, or plowing in the next year if the work is convenient. I do. This eliminates the crawler marks and other irregularities of the combine at the time of harvesting, and the straw that has been shredded and spread by the cutter at the time of harvesting is thrown in together with the weeds. Then, immediately after planting, if the soil becomes soft and soft by flooding the cultivated field and allowing 2 to 3 days to elapse, a substitute planting machine is introduced into the field, and the planting device 8, Substitute rotor 21
Is driven while driving, the scraper rotor 21 rotates and penetrates into the soil shallowly while traveling, and at this time, the respective ridges 22 of the scraper rotor 21 are inclined portions toward the muddy soil to one side. The diagonal part that pushes diagonally to the other side and then to the other side pushes the mud diagonally diagonally to the other side, and such repeated lateral extrusion is repeated. While being scraped, weeds, straws, old stocks, etc. are pushed into the mud and are leveled at the same time.
a and 21a.

In the above-described substituting process, the substituting width is larger by α on both sides than the actual planting width (planting interval L × number of columns n). 2α will be wrapped, and if reciprocating scratching is repeated, if the unscratched portion remains between the strokes, weeds will proliferate in that portion early and irregularities will remain in the field scene, but in the before and after scratching process The above problem can be solved by wrapping the side portions. The layer deeper than the scratched portion remains in the plowed state.

Immediately after such substitution, the planting device 8
Of the seedling 14 in the seedling mounting table 15 is scraped one plant at a time and planted in the scraped portion, on the side of which the rotating disc 39 forms a fertilizing groove, The nozzle 40 fertilizes the soil with the paste-like fertilizer pumped by the fertilizer pump 35 into the fertilizing groove. The fertilizer is not limited to the paste fertilizer, but may be a granular fertilizer. At the time of the above-mentioned shallow weeding, weeds, old plants or cut straws are pushed into the mud, so that planting can be performed well and growth of the weeds can be suppressed, and
The layer below the shallow layer is plowed and has a large number of small voids, so that the supply of oxygen to the roots and the elongation of the roots are improved, and the growth of seedlings is promoted. The substitute rotor 21 can be rotated in the reverse direction (the lower surface is rotated forward) or rotated forward.

[0015]

According to the present invention, a plurality of planting bodies 14 are arranged at a rear portion of the traveling vehicle 1 at predetermined planting strip intervals in the lateral direction.
The scraping rotor 21 which is forcibly driven to rotate between the planting bodies 14 and the immediately preceding wheel is supported in a horizontal direction, and both sides of the scraping rotor 21 are planted from the planting positions on both sides. Since it protrudes outward by more than 1/2 of the interval, it can be scraped off by extremely small power and alternately pushes back the topsoil that has been moved to one side by ridges that are inclined in the opposite direction to the other side. In this way, the surface layer can be sufficiently muddy and leveled by one-step scraping, and weeds, old plants, or cut straw can be pushed into the mud, and The planting work can be performed simultaneously with the work, and the working efficiency can be significantly improved. In addition, the planted seedlings do not become floating seedlings or lack of plants as in the no-tillage planting method, and after planting, the lower layer remains in a tilled state with many voids. Good growth of seedlings.

In addition, when the reciprocating planting is continuously performed,
Since the side of the margin width wraps between each stroke by scraping wider than the actual planting width, the unscratched portion does not remain in a band shape between each stroke, and the entire field is free of unevenness In this way, weeds can be prevented from growing early from the unscratched portion.
