Description

[Detailed description of the invention] The present invention relates to a groove-making device for planting beds for konjac seed potatoes, and more specifically, it is used to plant konjac seed potatoes on both sides of the roots along the growth row of previously cultivated wheat. This invention relates to a groove-making device for planting beds for konjac seeds, which can easily and quickly make grooves in a pair of planting beds simultaneously in one stroke and in the optimum bed condition for planting.

The right crop in the right place is the basis of agricultural work, and konnyaku cultivation is particularly popular in areas that have suitable soil conditions that contain a large amount of soil moisture and air (oxygen), have good drainage, and have an appropriate water retention capacity. is being carried out.

Konjac cultivation methods vary depending on the region, but recently a cultivation method has been proposed in which wheat (oat) is first cultivated in vacant land, and konjac seed potatoes are planted on both sides of the root of the growing row. However, since it is not easy to make grooves in the planting bed by hand, it is not possible for konjac cultivators to utilize the above-mentioned cultivation techniques efficiently for farming purposes.

In view of the above-mentioned circumstances, this invention was devised to meet the needs of konjac cultivating farmers, and is particularly designed to plant konjac seed potatoes on both sides of the roots along the growth row of the previous wheat. This konjac plant is constructed so that a pair of left and right planting beds can be easily and quickly cut simultaneously in one process, and in the optimal bed condition for planting, thereby making konjac cultivation labor-saving and efficient. It is an object of the present invention to provide a groove-making device for a seed potato planting bed.

The furrows are arranged so that the width of the furrow required for planting seed potatoes is the same as the plowing width. A transmission chain 17 is suspended between a sprocket 18 mounted on the rotary drive shaft and a sprocket 19 mounted on a pulley 6 mounted on the main shaft 7.

Reference numerals 20, 20 denote a pair of left and right soil-reducing plates that are located on both sides of the rotary frame 11a and inside the rotors 14, 14, and are installed between the rotary tilling shaft 13 and the axle 4. The soil induction plates 20, 20 have their lower edges 20a narrowing the previously cultivated wheat growing row, and are located on both sides of the root edge, so that the soil plowed and raised by the rotors 14, 14 covers the wheat growing row. In addition to protecting against
The upper edge is curved to expand rearward and diagonally outward, and serves to guide the thrown up cultivated soil to the side of the planting bed where the grooves have been made, while discharging the soil.
As shown in FIG. 6, the lower edges 20a of the soil absorbing plates 20, 20 are provided with an auxiliary plate 21, and have long grooves 20b, 20b bored in the vertical direction.

is a hitch for attaching a working machine installed on the rotary frame 11a.

Next, the operation of the present invention constructed as described above will be explained. Now, the rotors 14, 14 attached to both the left and right sides of the rotary tillage shaft 13 are positioned across the growth rows of the previously cultivated wheat a (see Figure 1 A), and the soil plate is installed to maintain a predetermined plowing depth. 20,2
A gauge 23 for maintaining plowing depth,
23, the auxiliary plate 21, etc. Therefore, when engine 2 is started, its power is transferred to pulley 8,
Transmission is transmitted to the main shaft 7 by the transmission belt 9 and pulley 6, and the axle 4 and the running wheels 5, 5 mounted on the left and right sides of the axle 4 rotate in the direction of arrow B through the deceleration transmission mechanism in the transmission case 3. Power is transmitted to the rotary drive shaft 12 by a sprocket 19, a transmission chain 17, and a sprocket 18, and the rotary tilling shaft 13 and the rotors 14, 14 mounted on the left and right sides thereof are moved in the direction of arrow C via the transmission mechanism inside the rotary case 11. Since the tilling blades 16, 16, . . . dig into the soil, rotary tilling is performed.

Thus, when the operator grips the control handle 10 and moves the machine along and above the growth row of wheat a in the direction of arrow A (the operator moves backward), the soil near the growth row of wheat a The rotors 14, 14, which rotate in the opposite direction to the rotation of the running wheels 5, 5, plow the cultivated soil in an upright manner, and the cultivated soil thrown up by the rotation of the tilling blades 16, 16, etc.
The soil is guided along the diagonally outwardly curved side surfaces of the tillage scattered soil regulating plates 22, 22, and falls on the opposite side of the wheat a growth row, leaving behind the tillage by the tillage blades 16, 16... A cross-sectional groove C is formed, and a part of the cultivated soil thrown up by the tilling blades 16, 16, etc. is carried around and distributed to the tilled scattered soil regulating plate 22,
22 falls into the trench from the rear end or midway, and a thin planting layer d of flexible scattered soil is formed at the bottom of the trench (see FIG. 1B and FIG. 5). Then, the konjac seed potatoes b are sown on the bed soil formed by this planting layer d, pressing them down somewhat (see Figure 1 C).
Since the seed potato b is kept in a stable posture without rolling by being pressed against the flexible bed soil, the main bud of the seed potato b remains in an upward position even if it is covered with soil in the subsequent work (see Figure 1 D). Or, the staggered series used for annual planting will not be disturbed in any way. Therefore, according to the present invention, the aircraft is simply a
By simply advancing above the growing row of wheat a, a pair of left and right planting beds for planting konjac seed potatoes b on both sides of the root of the growing row of wheat a can be created at the same time in one process, and the bed conditions are optimal for planting. Grooves can be created easily and quickly.

In addition, in the process of making grooves for the planting bed as described above, the control handle 10 is long protruding from the front part of the machine in the direction of movement, and the running wheels 5 run on the flat unmade groove ground. Therefore, while holding the control handle 10 while moving backwards, the operator can adjust the shift of the machine in the left and right direction by applying a very slight force using the wheat a growth row as a target line. The rotors 14, 14 attached to the rear of the machine body in the direction of movement rotate in the opposite direction to the traveling wheels 5, 5, so that the front and rear balance of the machine body is adjusted. A pair of left and right tillage depth maintaining gauges 23, 23 attached to the rear of the machine pass through the groove and maintain a predetermined tillage depth while regulating left and right deviations, so the rear of the machine does not shake. Although the machine does not sink, and therefore the worker has to move backwards while cutting the trench, the machine has extremely good maneuverability and stability, and it can always maintain the optimum floor condition for planting while maintaining straight line performance. It is possible to accurately create grooves for attached floors.

As mentioned above, seed potatoes will sprout after the planting process is completed, but if you cut the wheat green and spread it on the ridges at the right time, such as just before the sprouts emerge from the ground, transpiration of soil moisture will be prevented. As a result, early growth such as budding is improved, and the wheat leaves wither and become organic fertilizer.
In addition, by withering the roots that extend to the periphery of the seed potato, optimum air permeability and drainage can be maintained in the soil around the periphery of the seed potato, thereby making it possible to achieve ideal growth of the konjac potato.

In short, the present invention consists of a control handle that protrudes in the direction of movement of the aircraft, and a pair of left and right running wheels that are located below the base of the control handle and are placed on both sides of the handle, straddling the wheat growing rows that were created previously. and a pair of left and right guides located behind the running wheels, with their lower edges located near the roots across the wheat growth rows, and with their upper edges curved diagonally outward. It consists of a soil plate and a pair of left and right rotors located behind the soil plate and arranged on both sides of the wheat growing row so as to rotate in the opposite direction to the traveling wheels. The construction is such that a planting bed is created on both sides of the wheat growing row by the cooperative action of the plowing and lifting action of the tiller and the induced soil removal action of the soil-inducing plate. By simply advancing above the growing row, a pair of left and right planting beds for planting konjac seed potatoes on both sides of the root edge of the wheat growing row can be easily and simultaneously created in one process, and in the best bed conditions for planting. It is not possible to cut trenches quickly, but by cutting trenches while maneuvering in front of the machine, the operator can cut a flat, uncultivated trench with the target line of the previous wheat growth row. In addition to being able to move stably in a straight line, the rotor located at the rear of the machine rotates in the opposite direction to the running wheels located at the front of the machine, allowing the operator to adjust the balance between the front and back of the machine, allowing workers to move forward while moving backwards. Although it is a machine that creates grooves, the maneuverability and stability of the aircraft are always excellent, and it is possible to accurately create a planting bed with the optimal bed condition for planting while maintaining straight-line performance, making it an excellent choice for konnyaku. It has an extremely useful practical effect that allows cultivation to be carried out efficiently and labor-savingly.
