Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a scraping rotor in a scraping simultaneous planting machine in which a field in which grain culms are harvested is cultivated and seedlings are planted in the scratched portion while scratching the surface layer.

[0002]

[Prior art]

 Conventionally, a method of plowing the field where the grain culms were harvested and scratching the entire tillage layer, and a method of planting seedlings in the field after harvesting the grain culms in a non-tillage state, and the above fields There is already known a planting machine that cultivates only a narrow width and plants seedlings in this cultivated part.

[0003]

[Problems to be solved by the device]

 Of the above-mentioned known planting methods, the first method requires a great deal of labor because it scratches the entire tillage layer, and it is kneaded to a deep layer to eliminate voids in the soil. The device had to be planted separately. In the second method, the field at the time of planting lacks levelness due to combine crawler marks and dents at the time of harvest, and there are many old stocks and weeds. As a result, floating seedlings and poor growth occur. Furthermore, in the third method, it was difficult to keep the planted seedlings standing upright because the soil in the tilled part of the planted row did not have stickiness. When the surface layer of a field cultivated to solve these problems was shallowly scratched and seedlings were planted in this scratched area, the scratching rotor provided in the front part of the planting device was rotated and scratched. When doing so, a new problem arose that the mud flowing laterally from both ends of the scraping rotor pushed down the seedlings planted laterally.

[0004]

[Means for Solving the Problems]

 The present invention is equipped with a planting device in which a plurality of planting bodies are laterally arranged at predetermined planting strip intervals in the rear part of the traveling vehicle, and is freely rotatable in the front part of the planting device. The horizontal scraping rotor is supported horizontally, and the outer peripheral surface of the central scraping rotor except for both sides is provided with curved ridges that are bent to the left and right. The above problem was solved by providing a spiral ridge that scratches to prevent the mud water from flowing to both sides.

【Example】

 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 and 2 and rear wheels 3 and 3. The power of an engine 4 is transmitted by a mission case 5 to the traveling device and the rear portion of the body. The planting device 8 is connected to the rear of the airframe by a top link 6 and lower links 7 and 7 so as to be able to move up and down, and the planting device 8 has its input shaft connected to the PTO shaft. A transmission case 10 and a plurality of transmission cases with plants which are connected to the shaft through a universal joint and an intermediate shaft and which are transmitted through the transmission case 10 and a horizontal shaft in a pipe frame extending from the transmission case 10 to both sides. 12 ..., a plurality of planted bodies 14 driven by the planted transmission case 12 ..., and a leveling float 16 disposed at the bottom of each planted transmission case 12 ... It is composed of a seedling table 15 that reciprocates to There.

The ground leveling float 16 has a rear part pivotally supported by a planting transmission case 12, 12 above the rear part so that the rear part can be tilted up and down, and a front foil-shaped link is connected so as to be able to move up and down. Further, the central leveling float 16 also functions as a ground pressure sensing float, and is linked to a control valve of a hydraulic cylinder for raising and lowering the planting device 8 via a plurality of links. The grounding float 16 has a substantially constant ground contact height, and the ground-level float 16 is extended outward on both sides of its front portion. With this structure, the unevenness of the paddy field over the entire width of the wheel trace as well as the middle portion can be achieved. It is possible to satisfactorily level the soil and to suppress the generation of weeds and at the same time enhance the effect of the herbicide. Each plant 14 ... Plant seedlings on the It

The brackets fixed to the outer surfaces of the central and left and right planted transmission cases 12 ... are connected to forward stays 19. At the front end of each of the shafts 19 and 19, there is rotatably supported a scraping shaft 20 extending to both sides through bearings, and a transmission device to be described later rotationally drives the scraping shaft 20 so that the scraping shaft 20 moves to the front. A rubber (or steel) scraping rotor 21 ... Is integrally mounted on the shaft 20, and a zigzag-shaped bent lug (or meandering) is formed on the outer periphery of a portion other than both sides of the scraping rotor 21. , The projections 22 are formed on both sides, and when the scraping rotors 21 rotate on the outer circumferences of the scraping rotors 21 on both sides, a spiral-shaped spiral that guides muddy water toward the center side The ridges 22a are provided so as to project. The protrusions 22 may be formed by intermittently arranging bent V-shaped ones or alternately by alternately arranging left and right inclined ones. Further, the length of the scraping rotor 21 is longer than the planting width of one stroke, and both ends thereof are slightly projected from the outermost planting strip.

Explaining the transmission device next, the PTO shaft projecting rearward from the mission case 5 drives the input shaft of the planting device 8 via the intermediate shaft and the expandable joint 9 to drive the drive shaft 28. The attached sprocket 30 drives the sprocket attached to the input shaft of the reduction gear 29, and when the gear shift lever 32 provided on the rear side of the driver's seat 31 is operated, the gear is changed and the output shaft 34 of the reduction gear 29 is changed. Then, the output shaft 34 drives the input shaft of the gear case 35 which is interposed in the intermediate portion of the skimming shaft 20 via the expandable joint 33. In this case, the rotation direction of the scratch roller 21 is in the same direction as the wheel, and the peripheral speed is in the range of 1.2 to 1.5 times the running speed in the field of fragile soil such as volcanic ash soil. At low speeds, it is desirable to have high speeds in fields as hard as clay soils. The fertilizer pump 36 disposed below the side of the driver's seat 31 is also driven by the drive shaft 28.

The inlet of the fertilizer pump 36 is connected to the bottom of the fertilizer tank 37 via a suction hose 38, and the plurality of outlets are respectively attached to the planting device by separate hoses 39. The hose 39 is connected to the nozzles 40, ... In the middle of the hose 39, an indicator 41 mounted on the lower link 7 and a valve 42 with a lever for fixing a line.

[0010] Next, the description will be given of the scraping and planting. After the rice was cut in the previous year, it is cultivated in the fall with a rotary tiller attached to the tractor, or for the convenience of work, it is cultivated in the next year. To do. This eliminates the combine crawler marks and other irregularities at the time of harvest, and the straw that has been shredded by the cutter at the time of harvest is plowed with the weeds. Then, if the soil becomes loose by flooding the cultivated field immediately before planting for 2-3 days, a simultaneous scraping planter is introduced into the field to plant the planting device 8 , When driving while driving the scraping rotor 21, the scraping rotor 21 rotates and advances in a state of shallowly penetrating into the soil, and at that time, each ridge 22 other than both sides of the scraping rotor 21 ... Pushes the mud diagonally to one side at the slope toward one side, and the subsequent slope to the other side pushes the mud diagonally to the other side, and such reverse lateral extrusion is repeated. Therefore, the cultivated soil is well scratched in a shallow area, and weeds, straws, old plants, etc. are pushed into the mud and leveled at the same time. Also, the spiral ridges 22a on both sides guide the muddy water and mud to the center side of the machine width while scraping by rotating, so that the amount of muddy water pushed outward is reduced, which causes The seedlings planted in one direction will not be pushed down by the muddy water.

On the side of the seedlings to be planted, the fertilizing groove formed by the rotating disk fertilizes the paste fertilizer pumped by the fertilizing nozzle 40 by the fertilizing pump 36 into the soil. The fertilizer is not limited to the paste fertilizer and may be granular fertilizer. Since weeds, old plants or cut straws were pushed into the mud during the above-mentioned shallow scratches, the planting could be carried out well and the growth of the weeds could be suppressed. Since the lower layers are cultivated and have many small voids, oxygen supply to the roots and root elongation are improved, and seedling growth is also promoted.
