Features.

Since the Takatsuki formation machine of the present invention has the above configuration, the following effects can be achieved.
In the first aspect of the present invention, the tapping member shapes the side surface of the scissors with the scissor striking plate while the high scissor forming machine is in progress, and at the same time operates integrally with the reciprocating motion of the scissor striking plate. It is possible to shape the top surface of the reed horizontally by pushing the soil diagonally while tapping the top surface of the reed at small intervals, and significantly improving the efficiency of farming work compared to shaping the top surface of the reed separately Become.

The formed ridges are tightly tightened so that the side portions of the ridges are crushed at small intervals so that the sides of the ridges do not easily collapse, and at the same time, the upper surface portions of the ridges are raised by tapping members. The tapping member does not strike the upper surface of the ridge flatly with the plate surface of the plate by the advancement of the high ridge forming machine while flipping up and down with a knife with small intervals, but the lower edge of the narrow width of the tapping member The soil is shaped so that the upper surface is scraped in the forward direction while hitting linearly while playing the soil as if chopping with small knives at small intervals, so that the soil can be shaped in a soft state without being firmly tightened.
Further, at this time, since the tapping member is inclined backward on both the left and right sides, the force vector also works on the side, and the tapping member is pushed sideways while the soil hitting the front portion of the tapping member is pushed sideways. The upper surface of the rear kite that has advanced and passed the tapping member is leveled to a substantially horizontal state.

  The soft upper surface portion of the cocoon formed in this way provides air permeability and water permeability suitable for growing a crop, and is formed in a growth condition that is very favorable for the root of the crop.

  Also, since the soil on the top of the cocoon is soft, there is less resistance when inserting a finger into the soil, and finger puncture planting can be performed easily, greatly improving the efficiency of farming operations to handle such seedlings This also makes it possible to save the trouble of re-cultivating the top surface and re-cultivate it, and the effect on farm work is immeasurable.

  Furthermore, the present invention has a simple structure in which the tapping member is fixed to the punching plate of the high punching machine. In implementing the present invention, it is easy to manufacture and attach the member of the product, and this cost is high. Despite being a small part of a cocoon molding machine, some of the effects in farming work are very large as described above.

  Further, in the invention according to claim 2, the base portion of the tapping member is fixed to the support frame inside the hammering plate so as not to contact the plate surface of the hammering plate with a detour frame curved upward. The swing due to the detour frame causes elasticity of the swing of the tapping member, and the soil hitting the tapping member is ejected.

  Further, in the invention according to claim 3, since the height adjustment mechanism can adjust the vertical height of the tapping member in accordance with the height of the ridge, each time the height of the heel changes, the tapping member can be easily attached at any time. It becomes possible to make it the arbitrary height.

  In the invention according to claim 4, it is possible to easily adjust the inclination angle of the lower edge of the tapping member with respect to the horizontal direction at any time by the heel upper surface inclination angle adjustment mechanism, and to easily give a desired inclination to the upper surface of the heel. Become.

  According to the fifth aspect of the present invention, it is possible to adjust the inclination angle in the lateral direction with respect to the plate surface of the lower edge of the tapping member by a side angle adjusting mechanism from 40 degrees to 70 degrees, and by adjusting the angle, It is possible to effectively throw out the soil sideways at an angle according to the hardness.

  According to a sixth aspect of the present invention, the tapping member has a plate shape, and includes a plate surface vertical angle adjustment mechanism that enables adjustment of an inclination angle with respect to the vertical direction of the plate surface. The forward tilt angle can be determined according to the hardness of the soil for which the plate surface angle is desired to be obtained. The larger the angle, the harder the soil hardness on the top surface of the fence.

  According to the seventh aspect of the present invention, by providing a rearward horizontal reinforcing plate on the upper edge of the plate-shaped tapping member, the strength is further increased as a tapping member having an action of pushing out the plate surface even if the tapping plate is thin. Is possible.

The best mode for carrying out the present invention will be described below with reference to the drawings.
As shown in FIG. 1, the Takatsuki formation machine of the present invention includes a drive unit 11 having an engine and a mission covered with a mission cover 27 or the like at the center upper portion of a vehicle body 1a, and the drive unit 11 at the lower part of the vehicle body 1a. The left and right drive wheels 12 and 13 having a narrower vehicle width than the gap between the left and right wheels are provided, and the upper part of the drive unit 11 of the vehicle body 1a is provided with a pair of left and right handles 14 and 14 that are opened rearward. Grips 15, 15 gripped by an operator at the tips of the handles 14, 14, a grip control lever 16 for controlling the drive unit 11, and a forward / reverse switching shaft 26 are provided.

The left and right rotary claws 18 having a plurality of curved claws 19 that scrape the soil in front of the drive wheels 12 and 13 and scrape them to the left and right sides and the rotary claws 18 are connected to the drive unit 11. A rotation mechanism 17 is provided for rotation.
Further, a shaping plate 20 that covers the front part of the vehicle body 1a and forms a flat valley groove bottom is provided behind the rotating claw 18, and above the rotating claw 18 in front of the shaping plate 20, An upper cover 21 directly above and a projecting cover 22 projecting to the side are attached for spreading the soil scraped up by the rotating claws 18.
And in order to measure the working depth and running stability of the rotary claw 18 of the high punch molding machine 1, a frame with the upper cover 21 fixed is pivotally supported in the middle of the upper cover 21 so as to protrude. A guide small wheel 23 that supports the vehicle body 1a is attached to a lower end portion of a support shaft 24 having a direction handle 25 at the upper end.

  Further, as shown in FIG. 2, on the side of the drive wheels 12 and 13, the plate surface is arranged to the side at a position outside the position of the rotary claw 18 and corresponding to the inclination angle of the heel side surface. And a striking plate 8 provided with a support frame 7 that supports the plate surface on the inner surface, and is driven by the drive unit 11 via a reciprocating shaft 9 fixed on the vehicle body near the lower front side of the plate surface of the support frame 7. A reciprocating drive mechanism 10 is provided for reciprocating the scissor striking plate 8 so as to strike the side surface of the scissors at small intervals in conjunction with the driving of the drive wheels 12 and 13.

While the high punching machine 1 is in progress, the side surface of the scissors is shaped with the scissor striking plate 8 and at the same time is operated integrally with the reciprocating motion of the scissor striking plate 8 while tapping the top surface of the scissors at small intervals. A tapping member 2 that pushes the soil diagonally and shapes the upper surface of the basket substantially horizontally is disposed on the support frame 7 of the hammer hitting plate 8.
The tapping member 2 can be arranged on the support frame 7 in various manners. In FIG. 1, the tapping member 2 is laterally extended substantially horizontally from the front upper portion of the tapping plate 8 toward the oblique rear. A form in which the base portion of the tapping member 4 is fixed to the support frame 7 inside the hitting plate 8 via the detour frame 3 which is curved upward so as not to contact the plate surface of the hitting plate 8 while protruding. Show.

Next, the tapping member 2 will be described in more detail.
As shown in FIG. 2, the scissor hitting plate 8 is for leveling the upper surface U1 of the scissor U with respect to the hitting-type high scissor molding machine 1 that shapes the scissors by striking the side surface U2 of the scissors U. It is.
The tapping member 2 uses a long plate-like or rod-like metallic member. In this embodiment, the tapping member 2 is a plate-like member and will be described below.
As shown in FIG. 2, the long plate-like tapping plate 4 of the tapping member 2 has a length that is at least half of the ridge width so that the entire upper surface U1 of the ridge U can be leveled from both sides of the ridge U. It is sufficient if the length reaches the entire upper surface U1 of the ridge.
The tapping plate 4 has a constant plate width H and is fixed to the front end portion 3 a of the detour frame 3 with its plate surface upright.

Further, the fixing height position of the tapping plate 4 with respect to the tapping plate 8 is fixed so that the lower edge 4a of the tapping plate 4 reaches a position that matches the set height of the top surface U1 of the tapping plate 4 in use.
As shown in FIG. 4, the tapping plate 4 is in the range of 40 to 70 degrees from the plate surface proximity position near the front upper part of the surface of the tapping plate 8 diagonally to the plate surface obliquely backward (in the drawing). (Fixed to the support frame 7).
In this way, the tapping plate 4 is directed obliquely backward because the side surface of the scissors U is shaped with the scissor striking plate 8 while the high scissor forming machine 1 is running, and at the same time, the reciprocating motion of the scissor striking plate 8 This is because the top surface U1 can be shaped substantially horizontally by pushing the soil diagonally while tapping the top surface U1 of the ridge at small intervals.

In the setting of the angle of the tapping member 2 with respect to the surface of the hammering plate 8, the normal optimum angle is 45 ° to 50 °, but it is appropriately 40 ° to 70 ° depending on the hardness and soil quality of the soil. Decide on a range.
However, when the angle of the tapping member 2 is 40 degrees or less or 70 degrees or more, it is not preferable because the soil cannot be effectively pushed out toward the center.
If the angle is less than 40 degrees, it is necessary to make the length to reach the entire upper surface U1 of the bag, so that the tapping member 2 becomes heavy and difficult to swing. There are difficulties in strength.
If the angle is larger than 70 degrees, the force vector that moves the soil to the side becomes small, and even if the tapping plate 4 having a high plate width H is used, the soil that has been moved forward does not go to the side, but before the tapping plate 4. The soil rises over the tapping plate 4 and falls behind it, making it impossible to level the upper surface of the kite.

For adjusting the height of the tapping member 2, as shown in FIG. 7, a bypass frame receiving cylinder 5 into which the base end portion 3 b of the bypass frame 3 to which the tapping plate 4 is fixed can be inserted is attached to the support frame 7. The base end portion 3b of the bypass frame 3 that is vertically fixed and inserted is adjusted to an arbitrary height by a height adjusting fixing screw 6 provided on the side surface of the bypass frame receiving cylinder 5, and the bypass frame 3 at that position. It is possible to fix the base end 3b.
When the height adjusting mechanism is used, the height of the tapping plate 4 can be adjusted to an arbitrary height in accordance with the height of the upper surface of the ridge and the height of the ridge can be shaped.

  The tapping plate 4 may be fixed to the support frame 7 by projecting substantially horizontally from the position near the front upper portion of the surface of the tapping plate 8 diagonally rearward without using the bypass frame 3. Is possible.

  In the present invention, as shown in FIG. 3, while traveling through the high punching machine 1, the vertical swing angle (α in the figure) similar to the swing angle (α in the figure) of the punching plate 8 is simultaneously reciprocated. While moving, the tip portion of the tapping plate 4 swings and a vector of a slight lateral force is generated at the lower edge 4a of the tapping plate 4, and as shown in FIG. Help push the top of the soil sideways.

Further, since the vibration of the tapping plate 4 in conjunction with the vibration of the hitting plate 8 is directed obliquely rearward from the front upper part of the plate surface of the hitting plate 8, the side hitting plate 8 reciprocates. In this case, the rear part of the hitting plate 8 is shaken to a certain extent. Therefore, as shown in FIG. 4, the hitting plate 8 reciprocates in the horizontal direction at a horizontal vibration angle β interlocked with the swing angle of the hitting plate 8.
This reciprocating vibration of the tapping plate 4 is transmitted by the vibration of the hitting plate 8 and has the effect of flipping the upper part of the raised front soil toward the front side. For this reason, the lump of soil raised on the upper surface U1 of the ridge U is further crushed and softened.

In addition, the tapping plate 4 is arranged substantially horizontally from the plate surface proximity position near the front upper portion of the surface of the scissor hitting plate 8 toward the oblique rear side. However, as shown in FIG. The tapping plate 4 is fixed to the front end portion 3a via a support plate 31, and the support plate 31 is provided with an angle adjustment fixing screw 30 for adjusting an inclination angle with respect to the lateral direction of the tapping plate 4, and the tapping plate A side angle adjusting mechanism 32 that can be mounted so that the lower end edge 4a of 4 can be adjusted in the horizontal direction can be provided.
The movement of the high punching machine 1 generates a resultant vector A of the forward force vector B and the pushing force vector C with respect to the previous embankment. The lateral angle adjusting mechanism 32 causes the tapping plate 4 to move. When the inclination angle with respect to the side direction is increased as shown by the one-dot chain line in FIG. 5, the resultant force vector a of the forward force vector b and the pushing force vector c is generated by the movement of the Takatsuki molding machine 1, When the inclination angle is small, a lateral force vector c larger than the lateral force vector C is generated, and the soil swelled by the larger force is spread toward the side to be approximately horizontal. I will do it.
For this reason, even if the moving speed of the high punching machine 1 is increased, the tapping plate 4 is efficiently directed to the side without causing a covering over the leveled surface exceeding the leveled height H of the upper surface. You can push it away.

Further, by adjusting the angle of the side angle adjusting mechanism 32, it is possible to increase the moving speed of the Takatsuki molding machine 1 in accordance with the soil quality of the farmland, thereby realizing an increase in work speed.
Similarly, as shown in FIG. 6, by curving the tip end side of the tapping plate 4 (the portion indicated by reference numeral 33 in the figure), the soil that has been gathered partially and gathered sideways is gathered. It is also possible to prevent soil covering by pushing a large amount of soil on the tip side toward the side before the upper surface leveling height H of the tapping plate 4 is exceeded.

Furthermore, as shown in FIG. 8, the tapping plate 4 is fixed to the front end portion 3a of the detour frame 3 via a support plate, and the support plate 34 has a horizontal surface of the tapping plate 4 as shown in FIG. An angle adjustment fixing screw 35 is provided so that the inclination angle γ with respect to the direction can be adjusted, and a heel upper surface inclination angle adjustment mechanism 36 is provided so that the lower edge 4a of the tapping plate 4 can be attached so that the angle can be adjusted in the horizontal direction. be able to.
By adjusting the angle of the tapping plate 4 by the heel upper surface inclination angle adjusting mechanism 36, the upper surface U1 of the ridge U can be slightly inclined.
If the upper surface U1 of the ridge U is slightly inclined, for example, if the upper surface U1 has a downward slope, the upper surface U1 faces the sun, so the sunlight is effectively received to increase the temperature of the ridge surface U1 and It also promotes water and makes it easier for water to flow, so it can also prevent diseases of crops that don't like water pools or crops that tend to be root rot during the rainy season, depending on the type.

Further, as shown in FIG. 11, the tapping plate 4 is adjusted so that the inclination angle θ with respect to the vertical direction of the plate surface of the tapping plate 4 can be adjusted at the front end portion of the detour frame via the support plate 38. A plate surface vertical angle adjusting mechanism 37 by a screw 28 can be provided.
As shown in FIG. 11A, the soil in front of the tapping plate 4 is pushed out by the advancement of the Takatsuki molding machine, and the plate surface is perpendicular to the soil particle T inside the raised soil M. In the case of the direction, only the forward force vector d is generated. However, if the tapping plate 4 is moved by the plate surface angle of the tapping plate 4 as shown in FIG. A downward force vector e is generated. The vector e can be adjusted by the magnitude of the forward tilt angle θ. Therefore, the forward tilt angle is determined according to the hardness of the soil to be obtained. The larger the value, the more uniform soil K hardness can be obtained.
On the contrary, when the plate surface is inclined upward, a vector is generated so as to be lifted up, and the upper surface can be made softer.

  Further, as shown in FIG. 11, if a horizontal reinforcing plate 29 is provided rearward from the upper edge 4 b of the tapping plate 4 and the tapping plate is formed in an L-shaped cross section, the tapping plate 4 is reinforced. Even if the tapping plate is thin, high strength can be obtained.

  As shown in FIG. 9, if the plate surface of the tapping plate 4 is formed in an inferior arcuate cross section 39 with the front portion depressed, the lower end edge 4 a of the tapping plate 4 can be lowered when it swings downward during advancement. Since it advances like stabbed in the soil, when it swings up while moving forward, the soil jumps up and the soil becomes easier to disperse, and the softer upper surface U1 can be shaped.

  Also, as shown in FIG. 10, if the lower edge 4a of the surface of the tapping plate 4 is formed in a sawtooth shape or a rake shape 40, the lump solidified at the protruding tip can be effectively smashed to crush the top surface of the straw. Can be formed on a surface suitable for sowing.

  The present invention is used for a hitting type high punch molding machine, but can be used by attaching it to other types of punch shaping machines as long as it has a reciprocating mechanism for reciprocating a support frame at small intervals. It becomes.
