Description

[Detailed description of the invention] [Field of industrial application] The present invention is a leaf protection machine that can perform trench dredging and soil cultivation work in onion and other fields while protecting the leaves of onions and other crops so as not to damage them. Concerning Kanemizo dredging soil equipment.

[Conventional technology] Conventionally, in a management machine equipped with wheels and capable of installing a soil plate in the rear, it is necessary to use a management machine when dredging trenches and cultivating soil in fields such as onions, or when moving around a headland, etc. In order to lift the rear cultivation board, the front part of the machine is lowered using the handle, but if the front part of the machine hits the ridges or crops, problems such as irritation occur, and this structure is equipped with a leaf protection device. I couldn't do it.

[Problems to be solved by the invention] The invention makes it possible to properly equip leaf protectors on both sides of the management machine, so that ditch dredging and cultivating can be carried out well while protecting leaves for onions, etc. Moreover, when turning around on a headland, etc., the soil plate and leaf protector can be raised smoothly by simply operating the lever instead of lifting the handle like in the past, and the aircraft can be operated without any trouble. This means that it is possible to carry out the process in a convenient manner.

[Means for solving the problem] Therefore, in the present invention, the upright support plate connected to the hitch at the rear of the fuselage is equipped with a rotatable front part of the support arm, which is integrally connected with the soil plate at the rear. pivoted to,
An engagement pin operated by a lever connected to the support arm is installed so as to be able to engage at least the upper and lower parts of the support plate, and both protectors that can move up and down on the outside of the wheel are fixedly supported at the rear. The support arm is connected to the frame through parallel links, and the support arm and the parallel links are interlocked and connected.

[Function] Therefore, with both leaf protectors lowered on both sides of the wheels and the soil plate lowered at the rear of the aircraft, the aircraft is moved forward while protecting onions, etc. on both sides, and the soil plate is lowered. This makes it possible to perform trench dredging and soil cultivation work, and when the machine is to be rotated around a headland, etc., the support arm can be rotated upward while changing the engagement of the engagement pin using the lever. Once locked, the soil plate and both leaf protectors can be raised, allowing the aircraft to move around smoothly.

[Example] Next, the embodiment shown in the drawings will be described.

A indicates the management machine, with wheels 1a and 1b on both sides of the bottom.
The engine E is mounted in the front of the upper part of the transmission case 11 which is mounted on a shaft, the handle 12 is extended from the upper part of the transmission case 11 to the rear of the fuselage, and the hitch 3 is connected to the rear of the transmission case 11. It is constructed in the same way as the shape and structure.

A hitch 1 that can be detachably connected to the hitch 3
A fan-shaped support plate 4 is erected and fixed to the rear surface of the support plate 4, and cutout recesses 4 are formed at the top and bottom of the arcuate edge of the support plate 4.
b, 4a, and the front parts of both support arms 5, 5 extending rearward from both sides of the support plate 4 are rotatably pivoted to the front lower part of the support plate 4 via pins 14. A soil plate 2 and a stabilizing ring 16 similar to the conventional type are integrally connected to the lower part of a support rod 15 which is connected to the rear part of the arms 5, 5 and installed vertically.

A planar L-shaped arm 5a is extended from the rear ends of both support arms 5, 5, and a vertical support cylinder 17 is fixed to the end of the arm 5a, and a lever 6 long in the front and rear direction is connected to the intermediate portion thereof. A support shaft 18 fixedly installed above is rotatably fitted into the support tube 17, and one end of the horizontal engagement pin 7 has a spring 20 interposed in a connecting piece 19 installed above the tip of the lever 6. The other end side of the engagement pin 7 is loosely fitted so as not to come off the side, and the other end side of the engagement pin 7 is connected to both support arms 5,
5 and can be inserted into the notch recess 4 of the support plate 4.
a, 4b so that it can be fitted.

Further, at the rear lower part of the hitch 13, a middle part of a laterally long support rod 21 is fixed, and the support rod 21
Both support frame plates 22, 2 extending rearward from both end sides of
Both fixed support frames 9, 9 standing up on both sides are connected and fixed to the rear end of 2, and both wheels 1a, 1b
Both guard leaves 8 that can be moved up and down in an upright position on the outside of the
The rear portions of the support arms 5, 8b and both fixed support frames 9, 9 are connected via both parallel links 10, 10 consisting of upper and lower links 10a, 10b, respectively. The middle part of a long connecting rod 23 is fixedly installed in the connecting rod 23, and both ends of the connecting rod 23 are installed so as to be able to abut the lower edges of the upper links 10a in both parallel links 10, 10, respectively.

Therefore, as shown in Figs. 1 to 5, when the engaging pin 7 is elastically pressed by the spring 20 and its ends are fitted into both the support arms 5, 5 and into the lower notched recess 4a of the support plate 4,
A soil plate 2 is lowered and supported at the rear lower part of the machine body.
In addition, the upper link 10 is attached to both ends of the connecting rod 23.
a, 10a are supported, and both leaf support bodies 8
a, 8b are lowered and supported on the outer sides of both wheels 1a, 1b.

During work, run the wheels 1a and 1a between both rows of onions.
With 1b moving forward, both leaf protectors 8a and 8b will protect the onions in both rows, and the soil plate 2 will be able to dredge the grooves between both rows and cultivate the soil.

When the aircraft moves toward the headland and rotates, when the lever 6 is rotated in the direction of arrow A, the engagement pin 7 is pulled in the direction of arrow B, and the end of the engagement pin 7 touches the support plate 4. If you hold the lever 6 and lift it up as shown by the arrow C, both support arms 5, 5 will be removed from the pin 14.
As a result, the soil plate 2 is lifted up, and the parallel links 10, 10 are pushed upward by the rise of the linking rod 23, and both guard leaves 8a, 8b are also lifted. , the engagement pin 7 is inserted into the upper notch recess 4 of the support plate 4.
When they are fitted in accordance with b, both protectors 8a and 8b and the soil plate 2 can be raised high and locked as shown in Fig. 7, and the handle 12 can be raised as it is without any trouble as in the conventional case. This will allow the aircraft to turn.

Moreover, when carrying out the work again, both leaf protectors 8a, 8b and the soil plate 2 can be lowered by performing the reverse operation of the above-mentioned operation.

[Effects of the invention] As described above, the present invention is able to effectively perform trench dredging and cultivating while protecting leaves for onions, etc. by properly equipping the management machine A with the leaf protectors 8a and 8b on both sides. When moving the aircraft around a headland etc., instead of lifting the handle like in the past, you can lift the soil plate 2 and both guard leaves 8a and 8b high by simply operating the lever 6. In particular, the leaf protector can be lifted extremely high upwards by the parallel link extending forward from the fixed support frame at the rear end of the support frame plate extending rearward. Even between high ridges, the front part of the machine does not hit the ridges or crops like in the past, and the machine can be moved around easily without any problems, making it suitable for a simple structure. It has the feature that it can be implemented.
