Description

[Detailed description of the invention] Industrial field of application The invention relates to an agricultural management work machine that performs management work such as fertilization while moving along crop rows.

Conventional technology Conventionally, agricultural management machines that move along crop rows and perform management work such as fertilization between multiple rows at the same time have a horizontal frame with multiple fertilizers, etc. that correspond to the crop row spacing. It is known and used to attach horizontal frames to the rear of a tractor and tow the tractor at regular intervals.

Problems that the invention aims to solve By the way, when planting crops in the field, care is usually taken to ensure that the crop row spacing is equal throughout the field. When performing rice transplanters, the distance between the last row of one row (e.g., the 4th row in a 4-row rice transplanter, the 5th row in a 5-row rice transplanter) and the first row in the next row is often different from that of the other rows. It is often not equal to the row spacing of For this reason, in such fields, if management work such as fertilization over multiple rows as described above is performed, crops in rows with uneven row spacing may be damaged or
Inconveniences such as cutting down crops occur.

Furthermore, in a management machine that performs management work on multiple rows at the same time, if the machine body swings significantly from side to side, there is a risk that the work device may come into contact with the crops, damaging or mowing the crops.

In view of these conventional problems, the present invention is designed to move each work device along the crop rows even if the spacing between the crop rows is uneven or even if the machine body shakes from side to side during work. It is an object of the present invention to provide an agricultural management work machine that can perform various management works appropriately without the risk of damaging or mowing down crops.

Means for Solving the Problems The present invention has the following technical means for achieving its purpose.

That is, the agricultural management work machine according to the present invention is an agricultural management work machine that performs management work such as fertilization while moving along crop rows, and in which a plurality of work devices are mounted on a horizontal frame that is rollably supported on a traveling machine body. It is characterized in that it is hung so as to be rotatable in the left and right directions, and each working device is configured to run along the crop rows.

Function: The horizontal frame can roll freely relative to the traveling machine, and the multiple working devices are suspended from the horizontal frame so that they can rotate in left and right directions, so when performing management work in the field, multiple working devices can be If the machine is lowered in accordance with the crop rows, even if the crop row spacing is uneven, the working device will be guided by the hard stem near the root of the crop and will smoothly descend between the crop rows.
It moves reliably along the crop row.

In addition, since the plurality of working devices can roll freely relative to the traveling machine and can freely rotate in the left and right directions, even if the traveling machine meanders or shakes from side to side, each working device remains in line with the crop row. By moving reliably along the road, even in the above-mentioned cases, the crops are not damaged or mowed down, and various management operations can always be carried out appropriately and smoothly.

Example An embodiment of the present invention will be described with reference to the drawings.

The drawing shows an example of a soil fertilizer application machine as an agricultural management work machine. In Figures 1 and 2, 1
is an in-ground fertilizing machine, and this in-soil fertilizing machine 1 has one fertilizing device 3 attached to the left and right middle part of a horizontal frame (tool bar) 2, and a plurality of fertilizing devices 3 hung at equal intervals on both sides of the fertilizing device 3. These suspended fertilization devices 3 are rotatable in left and right directions around a hanging fulcrum 4. In addition, each fertilizer application device 3
The sled body 5 is equipped with a sled body 5 that slides on the field and a fertilizer injection nozzle 6, and the sled body 5 is attached to the horizontal frame 2 by a link mechanism 7 so as to be movable up and down. That is, as shown in FIGS. 3 and 4, the link 8 is pivotally attached to the horizontal frame 2 by a pin 9 so as to be rotatable in the left and right direction, and the link 8 is pivoted to the horizontal frame 2 so as to be rotatable in the left and right direction. are connected by parallel links 11, 11, and the fertilizer application device 3 is suspended as described above.
is rotatable in the left and right directions using the pin 9 as the hanging fulcrum 4, and is also movable up and down. The fertilizer application device 3 attached to the horizontal frame 2 can only be moved up and down. One parallel link 11 has an elevating adjustment handle 12 extending therefrom, and is provided with a holding mechanism 13 for raising and lowering states. Fertilizer pumps 14 are mounted on the horizontal frame 2 in correspondence with the respective fertilizer application devices 3, and each fertilizer pump 14 is connected to the corresponding fertilizer injection nozzle 6 through a flexible pipe 15.

The soil fertilizer applicator 1 configured as described above is attached to the tractor 16 via an upper link 17 and a lower link 18. That is, as shown in detail in FIG. 5, a mounting frame 19 is pivotally attached to the tips of the upper link 17 and the lower link 18 by pins 20 and 21, and this mounting frame 19 has no other attachments. The frame 22 can be attached or detached with one touch. This mounting frame 22 is provided with a swing support shaft 23 .
24 is a guide pin, 25 is a locking guide portion for the guide pin 24, 26 is a fixed arm, 27 is a fixed pipe fixed thereto, and 28 is a fixed pin.
A swing pipe 29 is attached to the left and right intermediate portions of the horizontal frame 2, and this swing pipe 29 is rotatably supported on a swing support shaft 23 of the mounting frame 22, so that the horizontal frame 2 is rotated with respect to the traveling aircraft. It is installed so that it can be rolled freely.

Note that since the mounting frame 22 can be attached to and detached from the attachment frame 19 with one touch, the horizontal frame 2 attached to the attachment frame 22 can be attached and detached together with the attachment frame 22 with one touch. There is a space between the horizontal frame 2 and the upper bending surface 30 of the mounting frame 22 to allow the horizontal frame 2 to roll, and the horizontal frame 2 has a space between the horizontal frame 2 and the upper bending surface 30 of the mounting frame 22, as shown in FIGS. 6 and 7. Wedge plates 31, 31 sandwiched between the two are provided on mounting shafts 32, 32 so as to be freely reversible.
33, 33 are the locking pins. Above wedge plate 3
1 and 31 remove the locking pins 33 and 33, insert them between the upper bent surface 30 of the mounting frame 22 and the horizontal frame 2, and then attach the locking pins 33 and 33 again to attach the horizontal frame 2. Can be fixed to prevent rolling. If the wedge plates 31, 31 are removed from between the upper curved surface 30 and the horizontal frame 2 and returned to their original state, the horizontal frame 2 can be rolled freely.

Note that the tractor 16 has fertilizer tanks 34, 34.
The fertilizer tanks 34, 34 and the fertilizer pump 14 are connected by flexible pipes 35, 35. The central fertilizer pump 14 is connected to a power take-off shaft 36 of the tractor 16 by a chain 37, and the left and right fertilizer pumps 14 are interlocked by an interlocking chain 38. 39 is a hydraulic cylinder for lifting and lowering the working machine; 40 is a weed guide for preventing grass straw from becoming entangled; 41, 41 are rear running wheels of the tractor 16; and 42 is a driver's seat.

In the device constructed as described above, all of the plurality of fertilizer application devices 3 except for the central one are rotatable in the left and right directions about the hanging fulcrum 4 with respect to the horizontal frame 2. Since the fertilizer applicator 2 can be rolled freely relative to the tractor 16, even if the intervals between the crop rows are uneven, the fertilizer applicator 3 can be guided by the hard stems near the roots of the crops and be reliably lowered between the crop rows. Moreover, it can be moved along the crop row. In addition, since the fertilization device 3 suspended from the horizontal frame 2 can be removed, it is possible to arbitrarily change the number of fertilization rows. In this case, if the left-right balance of the horizontal frame 2 is lost, wedge plates 31 and 31 are inserted between the horizontal frame 2 and the upper curved surface 30 of the mounting frame 22.
By sandwiching the fertilizers 3 into a rolling lock state, the fertilization depth of each fertilizer 3 can be maintained uniformly.

In the embodiment of the present invention, a fertilization device is exemplified as a management work machine, but it goes without saying that the present invention can be similarly applied to various management work machines such as drug injection, trench cutting, etc.

Effects of the invention The present invention is an agricultural management work machine that performs management work such as fertilization while moving along crop rows, in which multiple work devices can be freely rotated in the left and right directions on a horizontal frame that is rollably supported on a traveling machine body. Since the structure is such that each work equipment runs along the crop rows, if the traveling machine that pulls the management work equipment meanders in the field and the machine shakes from side to side, the crop row spacing will be uneven. Depending on various conditions, such as when the crop row is not straight or partially bent, each working device can be moved along the crop row to cut down or damage the crop. This has the effect of allowing various management tasks to be performed appropriately without any risks.
