Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coating device for agricultural membrane bodies, and its main object is to enable coating work along contour lines on sloped land to be carried out easily and reliably on both the outward and return trips.

In so-called mulching work for agriculture, regardless of whether the ridge is already formed or the ridge is formed simultaneously, an agricultural membrane is placed along the longitudinal direction of the ridge, and both sides of the ridge are covered with soil or embankment. Prevents the membrane from turning over.

By the way, if the farm is located on a slope such as a mountainous field, there are the following problems.

In other words, in the case of a tractor-pulled model, in order for the tractor to move along the contour line of the slope, the handle must always be turned in the direction of the mountain, otherwise the machine will slide down due to its own weight.
Therefore, the aircraft has no choice but to move upward and diagonally relative to the direction of travel.

Therefore, the coating device connected and fixed to the rear of the tractor is necessarily in an upwardly inclined position, and the coating operation cannot be carried out along the contour line.

In view of this, there is a so-called hand-type coating device proposed in, for example, Japanese Utility Model Publication No. 53-3164, but this prior art only requires forward work, which is extremely wasteful in work efficiency.

The present invention is based on the above-mentioned disadvantages and the above-mentioned prior art, and is a simple improvement that reliably solves these problems.Embodiments of the present invention will be described in detail below with reference to the drawings.

In the following embodiments, the covering work is performed together with the tilling ridge work, but the present invention can also be carried out exclusively for the covering work.

To outline the overall configuration with reference to Figures 1 to 3, 1

There is.

A tilling ridge forming body 5 driven by a power conductor 4 is provided on the moving machine frame 3 so as to be rotatable around a horizontal axis, and a ridge former 7 is provided at the rear of a cover device 6 that covers the working body 5. be.

The ridge shaper 7 has a forming part 8 that matches the shape of the ridge A that penetrates in the front and back (progressing direction), and in this example, the front elevational shape of the shaper 1 is shaped to follow the rotation locus of the work body 5. It is also designed to allow tilled soil to be introduced into the center.

In the embodiment, a downwardly curved arm rod 3B is connected to both ends of a pair of left and right arms 3A of the mobile frame 3, and a tool bar 9 is horizontally suspended on the arm rod 3B, and the ridge former 1 is connected to the arm rod 3B via the arm rod 3B.

A gauge body 11 which can be freely adjusted and fixed in the height direction via an adjusting tool 10 is provided on the outside of both sides of the ridge former I, and in this example, a wheel-shaped gauge body 11 having a protrusion on the outer periphery is provided. The tool bar 12K7 is supported by horizontally suspending a support tool 12K7-rubar 13 which is pivotally supported on the arm body 3A, and a stay 14 is slidably fixed to the tool bar 13.

The center portion of the machine frame 17 of the coating device 16 is connected via a traction connector 15 to the center portion of the moving device frame 3 in the left-right direction, that is, the center portion in the ridge width direction, so as to be pivotable about the vertical axis.

The traction connector 15 has a hollow square body 19 shown in FIG. 4 fixed to the rear part of a connecting arm 18 which is fixed to the tool bar 9 and formed into a rearwardly tapered shape. A hollow cylindrical body 20 having a flange 20A fixed thereto is fixed in the vertical direction, and a connecting shaft 21 is rotatably inserted through the hollow cylindrical body 20 and the hollow rectangular body 19. The connecting shaft 21 is prevented from coming off upward, and the downward movement of the connecting shaft 21 is prevented by the head 21A coming into contact with the upper end of the hollow cylindrical body 2o.

Therefore, once the connecting shaft 21 passes the stopper 22, it can be pulled out upward.

The machine frame 17 of the coating device is relatively rotatably fitted onto the connecting shaft 21 via a hollow cylindrical body 20 in the example, and in the example, the longitudinal center of a tool bar 23 installed laterally. As shown in FIG. 4, the fitting part 25 of the connecting fitting 24 is fitted into the connecting fitting 24, and the fitting part 25 of the connecting fitting 24 is fastened and fixed with the bolt 26. The machine frame 17 of the coating device is connected to the movable machine frame 3 so as to be pivotable in the left-right direction about the connecting shaft 21 of the traction coupler 15 as a fulcrum.

Furthermore, an elastic body 28 represented by a coil spring is hung between the moving machine frame 3 side and the machine frame 17 side of the coating device 16, so that the moving machine frame 3
In contrast, the machine frame 17 of the coating device 16 can be selectively switched in the left and right directions, and in this embodiment, as shown in detail in FIGS. 4 and 5, a switching lever 2 is provided on the head 21A of the connecting shaft 210.
9 is fixed in the middle, and the tip of the lever 29 and the machine frame 17,
In the embodiment, it is hung between a bridge plate 30 fixed to the connecting fitting 25 and a pin body 31 installed therein.

More specifically, a screw adjusting body 32 is provided on the pin body 31, and an elastic body 2 is provided between the adjusting body 32 and the lever tip 29A.
8 is removably hung, and the pin body 31 is located on the advancing direction line of the connecting shaft 21, as is clear from FIG.
By changing the position of the coating device 16 to the left or right of the traveling direction line LL, the coating device 16 can be selectively switched to the left or right according to the mobile frame 3, and the weight of the coating device 16 that is so-called sliding down can be reduced. It is constructed so that the tensile force of the elastic body 28 is used.

Note that since the weight of the coating device 16 that slides down varies depending on the slope of the field and fluctuations in the weight of the coating device 16 itself (due to adhesion of soil, etc.), in this example, it can be adjusted by the screw adjustment body 32.

Furthermore, in order to hold the switching lever 29 in both the left and right switching positions, a downward engaged body 33 is fixedly provided, and
An engaging body 34 is placed on the moving machine frame 3 at a left-right symmetrical position centering on the connecting shaft 21 at the left-right switching position of the engaged body 33.

Note that the engaged body 35 and the engaging bodies 34, 35 are both made of square bars to ensure reliable engagement.

In addition, in this example, the coating device 1 is used for work in a horizontal field.
6, a lock fitting 36 is rotatably fitted onto the pin body 31 as shown in FIGS. The movable machine frame 3 and the covering device 16 are arranged in a so-called tandem arrangement. It is considered to be in a fixed state.

Note that the lock fitting 36 is in contact with a stopper 37 to ensure this fixed state.

In addition, in FIGS. 1 to 3, the coating device 16 is provided with an agricultural membrane roll F on its machine frame 17 perpendicular to the longitudinal direction of the ridge, and a membrane treading device 38 on the left and right side, A soil covering device 39 is provided at the rear and outside of the ridge 38, and a leveling guide device 40 for the agricultural membrane F1 is provided.Furthermore, a so-called tsudumi-shaped ridge top surface suppression device 41 is provided at the rear of the ridge former 7. It consists of

In the embodiment, a left/right -X-1 fixing support 42 is provided on the tool bar 23 so as to be slidable and fixed, and a wound article support 43 is provided on the fixing support 42 so as to be adjustable and fixed in the height direction. 43, the rolled material F is installed in such a way that it can be freely fed out.

Further, a movable support 44 is pivotally supported in the height direction at the rear of the fixed support 42 and is connected to the movable support 44 in an unstable switching and fixing manner by a spring 45, and is attached to the movable support 44 in the grounding direction by a spring 46. In addition to providing a treading wheel 38A whose outer circumferential wheel is made of sponge or the like, a horizontal rod 47 in the front and rear direction is fixed to the support 44, and a wheel-shaped earth covering body 39A is provided on this horizontal rod 47. A treading wheel 38A is attached to the front end of the rod 47.
The agricultural membrane F1 that has passed through the leveling guide device 40 can be sandwiched between the roll 48 and the treading wheel 38A. 38B makes it possible to separate from the ground against the force of the spring 46.

Furthermore, the leveling guide device 40 is a rod-shaped rod-shaped removably installed on the cylindrical body 2γ of the connecting fitting 24 via a bolt 49 as shown in FIG. It has an arch-shaped leveling portion 40A that is curved.

Further, as shown in FIG. 4, the suppressing device 41 is constructed by fastening an extension arm 50 to the connecting fitting 24 with bolts 26, and having a support arm 51 pivotally supported at the rear of the arm 50, and biased by a spring 52 in the direction of contact with the ground. A roller support 53 is provided on the arm 51 so as to be adjustable and fixed in the height direction, and the ridge-like roller 41A is supported on the support 53 so as to be freely rollable.

In addition, earth cutting bodies 54 are provided on both sides of the rear portion of the ridge former 7.

In the embodiment described above, plowing work is carried out by moving the traveling work vehicle 1 forward and driving the work body 5, and the tiller is introduced into the ridge forming machine 7 and formed into a so-called embankment shape to create the ridges A. At the same time, the agricultural film body F 1 ffl from the winding 'r7)
The longitudinal force of the ridge A is introduced into the width direction center part of the ridge A, and the width direction both sides are sandwiched between the auxiliary roller 48 and the treading wheel 38A, and the leveling part 40A gradually draws out the width direction center part with tension. The membrane body F1 is covered along the direction, and a pair of left and right soil covering devices 39 that follow cover or fill soil on both sides of the membrane body F1 to carry out mulching work.

If the field is on a slope, the working vehicle 1 can be moved along the contour line by turning the handle upward as described above, and in this case, the lock fitting 37 is disengaged. Using the switching lever 29, the operating direction of the elastic body 28 is switched to the left and right directions in accordance with the inclined surface as shown in FIG. 61 or FIG. 62, and the coating device 16 is rotated around the connecting shaft 21 which is a vertical axis. Flexible coating device 1
The elastic body 28 prevents the 6 itself from sliding down the slope underground due to its own weight, etc., and even on a sloping ground, the contour line O--
The coating device 16 can be operated following the ridges A on O.

As shown in FIGS. 6 1 and 2, the elastic body 28 can be selectively changed in position in the left and right directions, and the engaged body 33 provided on the switching lever 29 can be selectively moved to the left and right engaging bodies 34 and 35. The lateral position of the covering device 16 is reliably maintained by the uniform engagement, and therefore, the covering device 16 can be maintained without any tears along the longitudinal direction of the ridge A of the agricultural membrane F1, or under the condition that it fits over the entire surface of the ridge. Multi-positioning is possible, and the engagement position of the engaged body 33 and the left and right engaging bodies 34, 35 can be changed to the left or right. For example, by changing and fixing the mounting position of the engaging bodies 34, 350 to the left or right, the pivot angle of the covering device 16 can be changed. In addition, by increasing or weakening the tensile force of the elastic body 28 using the screw adjusting body 32, it is possible to correspond to the deviation due to the weight of the coating device 16, etc.

In addition, by changing the operating portion 29B of the switching lever 29 to the left and right against the elastic body 28, the coating device 16 can be operated following the ridge A on the contour line OO during both forward and return work, and the switching Furthermore, the covering device 16, which is phantom to the moving machine frame 3 and pivoted around the vertical axis by the traction connector 15, is arranged in tandem as shown in FIG. As shown in the figure, by coming into contact with the switching lever 29 and preventing the action of the elastic body 28 and the pivoting of the traction connector 15, multi-purpose work can be performed even if the field is level.

The present invention connects a device 16 for coating the agricultural membrane F1 along the longitudinal direction of the ridge A to the moving machine frame 3 at a rear position of the traveling working vehicle 1 via a traction connector 15 that can be pivoted around a vertical axis. In this case, the coating device 160 machine frame 17 is attached to the mobile machine frame 3.
Since this relates to an agricultural membrane covering device characterized in that an elastic body 28 is provided to enable selection and switching in the left and right directions, even if the field is a sloped field or a curved ridge, the longitudinal direction of the ridge A is The agricultural membrane body F1 can be coated smoothly and easily by following the direction, and the covering device 160 can be covered by the elastic body 28.
Since the machine frame 17 can be selectively switched in the left and right directions with respect to the mobile machine frame 3, there is an advantage that it can be carried out for outbound work and return work, and combined with the simplification of the structure, its practicality becomes remarkable.

In addition, in the embodiment, the covering work is performed in conjunction with the tilling ridge work, but when the machine is dedicated to covering work, the moving machine frame 3
may be the traveling work vehicle 1 itself or a machine frame connected thereto.
