Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a ridge hardening and shaping device in a ridge growing machine, and is particularly suitable for mulching cultivation of crops, and is capable of forming tall ridges due to oversaturation and moisture. It has been devised so that it is in a firm hardened state with no risk of losing its shape, and that it can be shaped automatically and efficiently in one work step.

<Conventional technology and its problems> Conventionally, rotary tillage machines have been used to form ridges, but with this method, the tilled soil crushed and stirred by the rotary claws is finely divided, and it is difficult to form tall ridges in the future. Since it is not possible to build up and mold all at once, a soil cultivator is usually attached to the position immediately after the rotary claw.

However, even if the ridge shaping process is repeated, the entire formed ridge is made up of fine tilled soil, so the tilled soil is only formed by forcing it through the soil pot. The surface of the ridges is still soft and easily loses its shape due to rainwater or excessive dryness. This is especially true when cultivating with mulch in high ridges, installing plastic films, and growing crops. This will cause an obstacle.

<Means for Solving the Problems> The present invention aims to solve such problems, and for this purpose, a pair of left and right tilling shafts are horizontally and horizontally connected to the center drive case which is connected to the tractor body for transmission. The overall shape of the tiller extends out in a widening V-shape when viewed from above, and a plurality of rotary claws are placed on the inside of the tilling shaft, and one disc plow is placed on the outside of the tilling shaft, both of which are integrated with the tilling shaft. A pair of left and right horizontal bar sections parallel to the tilling axis are provided on the soil plate hanger arm, which is installed in parallel so as to be rotatable and also attached to the tractor body, and a pair of horizontal bar sections on the left and right that are parallel to the tilling axis are provided, as well as on supports that respectively hang down from the horizontal bar section. A soil plate is installed that covers the top and rear surfaces of the rotary claw and defines a ridge shaping opening that is generally inverted U-shaped in rear view, and the tilling shaft is rotationally driven by the power taken out from the tractor body. Then, a ridge is automatically created, consisting of a fine layer of tilled soil that is heaped up to the midpoint between the two tilling shafts by the rotary claws, and a coarse layer of tilled soil that is turned over by the disc plow so as to cover and integrate both left and right sides of the tilled soil layer. sculpted into a
This is a ridge-forming machine that shapes the ridges using the ridge-shaping opening of the soil plate that continues, and in particular moves back and forth in the left-right direction to a position immediately after the soil plate using a rotationally acting disc plow or a take-out conversion power from a tilling shaft. With a pair of left and right hitting pads facing you,
In order to harden the ridge after shaping with the soil plate, the pad is designed to automatically strike the surface of the ridge.

It is transmission-connected to the O-shaft by a universal joint shaft (17), and receives rotational power taken out from the tractor body (T).

As is clear from Fig. 4.5, the input shaft (16) is supported within the center drive case (14), and a bevel binion (18) is rotatably installed at the rear end of the input shaft (16). There is. (19) is a bevel gear shaft horizontally suspended in the upper position in the center drive case (14), and an input shaft (16) is attached to one end of the bevel gear shaft.
A bevel gear (20) that meshes with and rotates with the upper bevel pinion (18) is fixedly installed, and a transmission gear (21) with a small diameter is also carved in the middle part of the bevel gear shaft (19).

In addition, (22) is a reduction gear shaft horizontally suspended directly below and parallel to the bevel gear shaft (19), and a large diameter reduction gear (23) is carved in the middle of the shaft. ) is the small diameter transmission gear (21) on the bevel gear shaft (19).
), it is possible to obtain the necessary deceleration effect. (24) is the reduction gear shaft (22)
) are a pair of left and right helical gears that are fixed in position, and have mutually symmetrical tooth profiles.

(25) denotes a pair of left and right tilling shafts extending horizontally diagonally backward from both shaft cylinders (15) of the center drive case (14), and as a whole, they swing in a laterally formed V-shape when viewed from above. The minutes are arranged. In other words, both cultivation axes (
25) are projected in a mutually intersecting relationship state while maintaining a constant Guyang angle (θ) of about 20 to 35 degrees.

A helical gear (26) fixed to the base end of each tilling shaft (25) is correctly engaged with a helical gear (24) on the reduction gear shaft (22), so that both tillers can be The shafts (25) are rotated at the same time by the power from the input shaft (16) under a necessary deceleration state. In addition, the symbol (γ) in Fig. 6 indicates the tilling axis (25).
The intersection angle between the upper helical gear (26) and the helical gear (24) on the reduction gear shaft (22) is indicated.

Each tilling shaft (25) has its center drive case (
14) A short round shaft portion (25a) facing into the shaft cylinder (15)
and a long square shaft portion (2) exposed from the shaft tube (15).
5b), and its round shaft portion (25a) is equipped with a shaft cylinder (
15) by a plurality of bearings (27).

(28) is a plurality of mounting adjustment holes formed through the square shaft portion (25b) at regular intervals, and (29) is a fixing pin (30) inserted into the adjustment hole (2nd).
A single conical receiver type disc plow fitted to the protruding tip position of the square shaft portion (25b) of each tilling shaft (25) so as to be able to rotate together with the tilling shaft (25),
The concave curved surface is set to face inward.

Therefore, the rough cultivated soil cut by this will be turned inward, and the cutting marks - the end! Groove (G
) is opened to a constant width dimension (D). (
31) indicates the boss of the disc plow (29).

Further, (32) is also fixed by another fixing pin (33) inserted into the adjustment hole (28) at a midway position of the square shaft portion (25b) of each tilling shaft (25).
5), which is fitted so as to be able to rotate integrally with the sheath tube, and from now on, there are a plurality of rotary claws (34) facing in the radial direction.
are integrated into the plantation. Each rotary claw (34)
preferably has a concave shape, and
It is attached with its tip bent inward. Therefore, the fine tilled soil that has been plowed and crushed will naturally be piled up in a heaped position in the middle of both tilling shafts (25), and also in a position directly below the center drive case (14). No residual tillage is generated.

In other words, on both tilling shafts (25) which intersect with each other at a constant gearing angle (θ) as described above, there are a plurality of rotary claws (34) at the inner position and one at the outer position.
Each disc plow (29) has a tilling shaft (
25), so that when such a ridge growing machine is moved forward by the tractor body (T) and its tilling shaft (25) is rotationally driven, the ridge growing machine shown in FIG. As is clear from the rotary claw (34
) is dammed up from both left and right sides by the disc plow (29), and at the same time, a fine tilled soil layer (A) is generated in a heaped state at a position midway between both tilling shafts (25). As a result, the coarse cultivated soil N (B) by the disc plow (29) is deposited on both the left and right sides of the fine cultivated soil N (A) in an inverted state, and the grass is grown at a certain height. Sa()■) and width dimension(
It is shaped as a ridge (35) having W).

In that case, since each tilling shaft (25) is dotted with the plurality of adjustment holes (28) described above, the fixed bin (
30) By replacing and operating (33), the mounting positions of the rotary claw (34) and disc plow (29) can be adjusted separately.
This means that the molding width dimension (W) of 35) can be varied widely. However, the sheath tube for implanting the rotary claw (34) (
32) and the boss (31) of the disc plow (29),
By achieving mutual unity, its rotary claws (
34) and the disc plow (29) may be adjusted simultaneously.

Furthermore, the molding height (H) of the ridge (35) can be changed by changing the rotation radius (R1) (R2) of the disc plow (29) or rotary claw (34). be. In this regard, on the concave side, the rotation radius dimension (R1) of the disc plow (29) and the rotation radius dimension (R2) of the rotary claw (34) are set to be almost the same, but the former has a larger diameter than the latter. It may be dimensioned to .

Furthermore, (36) is a pair of left and right hanger arms attached to the hitch frame (13) of the tractor body (T), which can be lifted around the horizontal axis at the front end and kept in a state of non-use. It has become. Both of the hanger arms (36) extend to a position rearward of the tilling shaft (25), and each rear end serves as a horizontal bar section (37) parallel to the tilling shaft (25). The distribution is arranged equally in a V-shape with a wide rear. The angle at which the F-shape intersects is determined to be substantially equal to the Guyang angle (θ) of the tilling shaft (25).

(38) is a plurality of mounting adjustment holes that are opened through the horizontal bar portion (37) of each hanger arm (36) at regular intervals, and (39) are left and right holes that hang from the horizontal bar portion (37). They are a pair of pillars, the upper ends of which are attached to the horizontal bar part (37) by means of fixing pins (40) that are replaced with the adjustment holes (3rd), and the lower ends of the pillars (39) as well. A cultivating soil plate (41) is fixedly integrated in each part. A ridge shaping opening (S) which has an opening in the shape of an inverted U-shape as a whole when viewed from the rear is defined by the mutual slope of the painting platform (41).

As is clear from FIG. 3 and FIGS. 9 to 11, each of the soil plates (41) is curved into an arc shape in side view, covering the top and rear surfaces of the rotary claw (34). a first plate part (41a) which is curved in an arc shape following the first slope part (41a) and facing each other in a rear view to define the ridge shaping opening (S); In particular, the first plate part (41a) and the second plate part (41b
) is set as a step (41c) having a constant height difference, and also as a ridge line (X-X) substantially parallel to the tilling axis (25) when viewed from a plane.

Also, regarding the positional relationship between each of the soil plates (41) and the disc plow (29), the arc-shaped first plate portion (41)
a) is the concave curved surface (29) of the disc plow (29) from the outside
On the other hand, the arc-shaped second plate part (41b) also faces the rear edge of the disc plow (29), where the cutting action takes place, so as to wrap it inside the disc plow (29).
The above-mentioned pillar (39) vertically extends from the second plate part (41b)
is located immediately behind the disc plow (29) so as to face the convex curved surface (outer surface) of the disc plow (29).

The boundary positions of the 1.2 plate parts (41a) and (41b) are welded together, but the boundary is located along the ridge line (X -X
), the second plate part (41b) that forms the ridge shaping opening (S) is also moved forward by a certain amount (Y) from both the left and right end positions at the intermediate position of the slope (41) of the art platform. Moreover, the boundary is a stepped part (41c) with a difference in height, and the first plate part (
41a) has an arc shape as long as possible when viewed from the side, and follows the rotation trajectory of the rotary ring (34), so the rotary ring (34) crushes fine soil and the disc plow (29) coarsely crushes the soil. The inverted cultivated soil does not accumulate inside the boundary position and can be moved extremely smoothly to the soil plate (41).
), particularly into the second plate portion (41b), and as a result, a highly accurate shaping state of number (35) can be obtained.

The present invention is also equipped with a movement mechanism that further hardens the surface of such ridges (35) and reliably prevents deformation.

That is, in FIG. 1.2 and FIGS. 12 to 14, the following reference numeral (42) indicates the disc plow (2).
It is a cam plate fixedly integrated with the convex curved surface (outer surface) of 9), and has a plurality of radially extending outward protrusions (43). In this regard, the government welds the cam plate (42) to the disc plow (29), but the cam plate (42) has a waist that can rotate together with the disc plow (29) and the tilling shaft (25). This may be attached to the tilling shaft (25) by means of the above-mentioned fixed bin (30) as a separate detachable member from the disc plow (29). In addition, a convex strip of a certain length (
43), it can be easily brought into contact with the free rolling rollers described later, and the rolling operation of the rollers can be maintained stably.

(44) faces the outside position of the cam plate (42),
It is a rocker arm of a certain length that extends along the front-rear direction, and the middle part of it is the support (39) of the soil plate (41).
It is pivoted by a vertical axis (45) so that it can see-saw horizontally. (46) is its vertical axis (4
5), and integrally extends from the mid-height position of the support column (39). (47) is an idling roller pivotally supported at the front end of the rocker arm (44),
The protruding strip (43) comes into contact with the cam plate (42).
So to speak, people transfer jobs as if they were going up and down.

Also, (48) always connects the roller (47) to the cam plate (42).
It is a helical spring that is biased to press against the rocker arm (44), and is attached to the vertical shaft (45), and its cut-off tip is locked in the middle of the rocker arm (44). (49) is a striking pad assembled and fixed to the rear end of the rocker arm (44),
41) with a small distance (L), and when viewed from the rear, the second plate part (41) of the soil plate (41)
It is curved in the same arc shape as 41b). However, as long as they have substantially the same shape, it is not necessarily limited to the arc shape, but may be an inverted shape in rear view as shown in FIG. 15 depending on the desired ridge (35), or Of course, other angular shapes can also be used.

Therefore, when the disc plow (29) is rotated, its rotational motion is converted into a horizontal seesaw motion of the rocker arm (44), and the rocker arm (44) is rotated.
The hitting pad (49) attached to the f& end of 44) performs a reciprocating movement in the left-right direction, as if hitting the surface of the ridge (35) in a so-called shoulder-beating manner.

The stroke of the reciprocating motion or the strength of the striking force is determined by the moment action length of the rocker arm (44) - the sheath above-mentioned convex line (
The number of strikes per revolution of the disc plow (29) can be selected depending on the number of protrusions (43) attached to the cam plate (42) or their mutual relationship. It is also possible to appropriately determine the interval.

In that case, if the striking pad (49) is formed to be excessively large, the striking force will increase due to the decrease in surface pressure. It is desirable to form it in a width dimension and to apply hammering as frequently as possible. In addition, it is preferable to minimize the distance (L) between the soil plate (41) and the second plate portion (41b) as much as possible in order to prevent the ridge (35) from losing its shape during pounding! : I can say it.

In any case, the hanger arm (36) of the soil plate (41)
), as mentioned above, its horizontal bar part (37) is connected to the tilling axis (
25), and the horizontal bar part (37) has multiple mounting adjustment holes (38).
are installed in an open row, so fixed bins (4
0) and the soil plate (41) that will hang down from now on.
By adjusting the position of the ridge (35), the shaping action corresponding to the changing width (W) of the ridge (35) can be normally performed at all times.

Since the rocker arm (44) is assembled and held on the pillar (39) of the soil plate (41), the striking pad (49) is also naturally connected to the soil plate (41) and the ridge ( 35), it is possible to immediately respond to the changing width dimension (W), and therefore no separate adjustment work is required to accommodate the change. The horizontal bar portion (3) of the hanger arm (36) changes according to the change in the mounting position of the rotary claw (34) or disc plow (29) with respect to the tilling shaft (25).
It is sufficient to adjust the mounting position of the soil plate (41) with respect to 7).

<Effects of the Invention> As described above, the present invention extracts the pair of left and right tilling shafts (25) laterally and horizontally from the center drive case (14) which is transmission-coupled with the tractor body (T) as a whole in a plan view. Spread out in a legal H-shape, and its cultivation axis (25)
A plurality of rotary claws (34) are provided at the inner position of the plow, and one disc plow (29) is also provided at the outer position.
Both of them are installed in parallel to the tilling shaft (25) so as to be rotatable, and the soil board hanger arm (36) attached to the tractor body (T) is parallel to the tilling shaft (25). A pair of left and right horizontal bar portions (37) is provided, and the upper and rear surfaces of the rotary claw (34) are covered by the support columns (39) that hang down from the horizontal bar portions (37), and the upper and rear surfaces of the rotary claw (34) are Attach the soil plate (41) that defines the ridge shaping opening (S) in an overall almost inverted U-shape, and attach the tilling shaft (25).
is rotated by the power taken out from the tractor body (T), and both tilling shafts (25
) A fine cultivated soil layer (A) that is raised to the intermediate position between
and a rough tilled soil layer (B) that is inverted by a disc plow (29) so as to cover and integrate both left and right sides of the cultivated soil 1iJ (A),
The ridge shaping opening (
S) is a ridge-forming machine that shapes the ridges by S), and in particular moves back and forth in the left-right direction to a position immediately after the soil plate (41) by the rotationally acting disk plow (29) or the extraction conversion power from the tilling shaft (25). In order to harden the ridges (35) after shaping with the soil plate (41),
) so that the surface of the ridge (35) is automatically struck, which has the effect of completely eliminating the problems of the prior art mentioned at the beginning.

That is, since the striking pad (49) automatically acts to strike the furrow (35) in response to the rotation of the tilling shaft (25) and the disc plow (29) attached to it, The first process of creating ridges is extremely efficient,
Moreover, the ridges are hardened and never lose their shape from the surface (35
) can be completely formatted. Therefore, the ridge (35)
It is now possible to freely shape the tree to be as tall and narrow as possible without any restrictions, and it is extremely useful not only for relatively low flat ridges, but especially for mulching cultivation in high ridges. It can be said that the work of laying plastic film can also be carried out automatically and appropriately.

Also, inside the center of the ridge (35) is a rotary claw (34).
The above-mentioned pounding pad (
After being hardened in step 49), the inside of the wall still remains soft, so it becomes an ideal ridge (35) on which various crops can be planted. Furthermore, if the movement mechanism of the striking pad (49) as shown in the illustrated embodiment is adopted, the mechanism will be extremely rational and can be easily attached to existing ridge forming machines.

Similarly, as embodied in the illustrated embodiment, the striking pad (49) is assembled and held by the rocker arm (44) to the support (39) of the soil plate (41),
If the support (39) is suspended from the horizontal bar part (37) of the hanger arm (36) parallel to the tilling shaft (25), the mounting position can be freely adjusted.
Coupled with the fact that the mounting position of the disc plow (29) can be adjusted, it is possible to easily adapt to the changing molding width dimension (W) of the ridge (35). Since there is no need to add a separate position adjustment work for only the pad (49), the practical benefits can be further increased.
