Embodiments of the present invention will be specifically described below with reference to the accompanying drawings. In the drawing, reference numeral 1 denotes a furrowing machine that is connected to a three-point link connecting mechanism including a top link and a lower link provided at the rear of a tractor (not shown) to perform a furrowing operation. This ridge coater 1
Has a transmission frame 2 also serving as a main body frame, which is orthogonal to the traveling direction of the machine body, and is provided in a lower right state in FIG. The transmission frame 2 is provided with an input shaft 3 projecting forward from the inclined upper end portion and receiving power from a PTO shaft of the tractor via a universal joint and a transmission shaft.
A top link connecting portion 4 protruding upward from the inclined upper end portion is provided, and lower link connecting portions 5 and 5 extending left and right from the inclined upper end portion are integrally connected by means of welding or the like to provide a three-point link of the tractor. It is designed to be connected to a connection mechanism.

The transmission frame 2 supports a pretreatment body 6 composed of a rotary tilling device that plows the original ridge and the field and swells the field into a ridge shape on the front side, and is plowed by the pretreatment body 6 on the rear side. A ridge 7 composed of a polygonal conical drum for shaping the soil into ridges is supported. Then, the power received by the input shaft 3 from the tractor is transmitted to the pre-processing body 6 and the ridge body 7 via the transmission frame 2, and each is rotated in a predetermined direction to perform each operation. .

The pre-processing body 6 has its axis of rotation 8 arranged in parallel with the traveling direction of the machine body, and the axis of the axis of rotation 8 is located forward from the transmission end of the transmission frame 2. The shafts of the front output shaft 9 protruding from each other are connected concentrically. A rear output shaft 10 protrudes rearward from the transmission end of the transmission frame 2 integrally with the front output shaft 9. The rear output shaft 10 is provided with a double joint (universal joint) 11 from the rear output shaft 10. Power is transmitted to the input shaft 12.

The upper part of the pretreatment body 6 is covered by an upper cover 13, and the upper cover 13 is supported by an upper cover slide device 14 so as to be slidable left and right. The outside of the pretreatment body 6 is covered with a side cover 15, which is
, And the lower end position of the side cover 15 is regulated by the parallel link 16. An elastic plate 17 such as a rubber plate is attached to a lower portion of the side cover 15, and has a flexible structure that elastically deforms and returns when it comes into contact with the bank.

On the rear end of the support frame 18 projecting rearward from the rear side surface of the transmission frame 2, the front end of the transmission case 19 can be turned up and down via a fulcrum pin 20. I support it. The rotation center of the fulcrum pin 20 is provided substantially equal to the rotation center of the ridge 7. A turning handle 21 is provided between the upper surface of the ridge body transmission case 19 and the support portion on the side of the transmission frame 2 so that the vertical height of the ridge body 7 can be adjusted. The ridge body transmission case 19 is bent in an L-shape, and the ridge body 7 is attached to the tip of the bent portion so as to rotate, and the input shaft 12 projects forward from the bent portion. , Through a double joint 11.

In this embodiment, the ridge 7 has a polygonal cone-shaped drum 7 having a dodecagonal ridge line and a flat portion.
Cylindrical body 7a projecting horizontally from the center of
The polygonal conical drum 7 is eccentrically fixed to the horizontal cylindrical body 7a. Above the polygonal conical drum 7,
The cover 2 is supported by the ridge body transmission case 19 via the support arm 22a.
2 is a size that covers only the parts of the ridge 7 that are required for safety,
And the tractor operator has a conical drum 7
It is provided in a state where the work state of can be observed. Then, the soil excavated by the pre-processing body 6 with the advance of the aircraft is applied to the inclined surface of the original ridge by the polygonal cone-shaped drum 7, and the horizontal top of the original ridge is applied by the horizontal cylindrical body 7a. I am trying to ridge.

At the left end of the lower link connecting portion 5,
A triangular disk-shaped gauge wheel 23 is provided so as to be vertically adjustable by a vertically adjustable support portion 24. A stand 25 is provided at the front lower side of the gauge wheel 23 so as to be detachable from the stand support 26. further,
A stand 27 is detachably provided below the outer end of the pretreatment body 6. These stands 25 and 27 are unnecessary during work, and are detachably provided or provided so as to be foldable.

At a substantially central portion of the ridge coating machine 1 in a plan view, a front-rear horizontal level 28 for detecting the front-rear horizontal state of the body and a left-right horizontal level 29 for detecting the left-right horizontal state of the body are provided. The horizontal state is detected and the adjustment is performed.

In the ridge coater 1 having such a configuration,
Since the transmission frame 2 that transmits the power received from the tractor to the input shaft 3 to the pretreatment body 6 and the ridge body 7 has the function of a support frame that supports the pretreatment body 6 and the ridge body 7 and the like. The weight of the entire ridge coater 1 is greatly reduced.
As a result, the load on the tractor is remarkably reduced, and troubles in the hydraulic system, poor weight balance, and the like, which occur in the conventional heavy ridge coater, are eliminated.

The rotary handle 2 provided on the transmission frame 2 side
1, the ridge 7 can be easily adjusted up and down, and the cover 22 moves up and down together. Also, the cover 22
Since the size and shape cover only the necessary parts of the ridge 7, the safety of the ridge 7 is ensured while being lightweight. Furthermore, since the cover 22 is attached so that the operator who operates the tractor can observe the working condition of the ridge 7, the operator can easily look at the working condition of the ridge 7 from behind. You can do it. As a result, the working accuracy and working efficiency of the ridge 7 can be improved.

[0021]

As described above, according to the ridge coater of the present invention, the following effects can be obtained.

[0022] The power received from the traveling body to the transmission frame also serving as the main body frame is transmitted to the pretreatment body and the ridge body, and a rotation fulcrum is provided on the transmission frame side to support the ridge body so as to be vertically adjustable. Since the cover of the ridge is attached to the transmission case of the ridge, the cover is moved together with the up and down adjustment of the ridge, and the accuracy of the cover can be maintained well.

[0023] Since the cover is formed in a size and a shape to cover only necessary portions of the ridge, the safety of the ridge can be ensured while the weight of the cover is reduced.

[0024] Since the cover was attached so that the pilot operating the traveling aircraft could observe the working condition of the ridge,
The operator can easily observe the work situation of the ridges while facing the rear while maneuvering the traveling body, and can improve work accuracy and work efficiency.
