Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice transplanter with a fertilizer application in which a fertilizer application device is mounted above a planting mechanism for taking out and planting seedlings from the lower end of a seedling stand in the seedling planting device.

[0002]

2. Description of the Related Art In the rice transplanter with a fertilizer application described above, conventionally, as shown in, for example, Japanese Utility Model Laid-Open No. 3-22616, the fertilizer application is arranged in a fixed position by a support frame erected from a planting transmission case. It was configured to do.

[0003]

However, in the above-mentioned conventional structure, since a plurality of tall fertilizer application devices are arranged above the seedling planting site for each row, for example, work in a certain field can be performed. At the time of completion, when taking out the placed seedlings that are slightly left on the seedling stand, this fertilizer application would be an obstacle and would make the work difficult to perform, and there was room for improvement. The present invention aims to eliminate the above-mentioned problems.

[0004]

According to a characteristic configuration of the present invention, in the rice transplanter with a fertilizer application described at the beginning, the fertilizer application work on the lower side is performed on a support rail erected from a frame of the seedling planter. It is configured to support up and down position changeable between a position and a position retracted upward, and the other end of the wire whose one end is fixed to a support rail is connected to the fertilizer application device, and a movable pulley that acts on the wire, The urging mechanism is configured to urge the fertilizer application to move upward in the upward direction.

[0005]

[Function] A fertilizer application device can be installed at a work position above the planting mechanism to effectively perform fertilizer application, and when a small amount of the remaining seedlings is taken out from the seedling stand after the planting work is completed, fertilizer application is performed. By moving the device upward along the support rail to a higher position, the outer side of the lower end of the seedling stand is largely opened, and the seedling removal work can be performed easily. Further, at this time, it is necessary to move a plurality of fertilizer applicators having a large total weight upward for a large stroke, but the urging mechanism lifts and urges the fertilizer upward, so that the lifting operation force is small. Finished, work can be done easily. Moreover, since the urging mechanism is configured to move the moving pulley, the operation stroke of the urging mechanism is half the movement stroke of the fertilizer application device, and a small size can be used.

[0006]

[Effects of the Invention] Therefore, the fertilizer supply is set as close as possible to the seedling planting place, and the working position of the fertilizer application is set at a position close to the planting mechanism in order to minimize the delay time required for downflow guidance. Although it can be freely operated, it can be evacuated to a place where it does not interfere with the work of removing the remaining seedlings on the seedling stand, and the seedling removal work can be performed efficiently. Furthermore, the heavy fertilizer application can be moved lightly and the operability is good, and the rational configuration allows the urging mechanism to be small while increasing the evacuation movement stroke of the fertilizer operation. Since the required operation stroke of the urging mechanism becomes small, there is also an advantage that the change in urging force before and after the movement can be made small.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice transplanter equipped with a fertilizer application device, which is equipped with a fertilizer application device for feeding fertilizer to a field along with planting of seedlings.

[0002]

2. Description of the Related Art In a rice transplanter with a fertilizer application as described above, the fertilizer application apparatus is fixed at a predetermined position, and the predetermined position is set as a working position of the fertilizer application apparatus for feeding the fertilizer to the field and fixed at the work position. Many fertilizer applicators are configured to send fertilizer to the field.

[0003]

Since other devices are often disposed near the working position of the fertilizer application in the rice transplanter with the fertilizer application as described above, the fertilizer application at the work position and the vicinity thereof are often performed. It may be difficult to perform maintenance work on other devices. An object of the present invention is to facilitate maintenance work on a fertilizer application device and other nearby devices in a rice transplanter equipped with a fertilizer application device.

[0004]

A feature of the present invention is that a rice transplanter with a fertilizer application device is constructed as follows. [1] Equipped with a fertilizer application that feeds fertilizer into the field along with planting of seedlings, and extends in a work position between a work position for feeding the fertilizer into the field and a non-work position apart from the work position. Of the fertilizer application, the output part is placed at a position different from the fertilizer applicator at the working position, and one of the drive rods is connected to the input part of the fertilizer applicator. In the working position, the other side of the drive rod is configured to be connectable to and disconnectable from the output part only along the direction intersecting the moving direction of the fertilizer application between the working position and the non-working position, and the other side of the drive rod is output. The power of the output unit is transmitted to the input unit via the drive rod as the push / pull power in the state of being connected to the unit. [2] In the configuration of [1] above, the output part is arranged below the fertilizer application device at the working position.

[0005]

[I] According to the feature of claim 1, it is possible to move the fertilizer application located at the work position to the non-work position apart from the work position. As a result, by moving the fertilizer application from the working position to the non-working position, the maintenance work of the fertilizer application can be easily performed without being disturbed by other devices arranged near the work position. Maintenance work of other devices arranged near the work position can be easily performed without being disturbed by the fertilizer application device.

When the fertilizer applicator is moved between the working position and the non-working position, the fertilizer applicator can be moved while maintaining the posture at the work position. The fertilizer in the fertilizer application does not spill, and it is not necessary to take out the fertilizer from the fertilizer application for the moving operation.

[II] When the power of the output section at a position different from that of the fertilizer application apparatus is transmitted to the input section of the fertilizer application apparatus located at the working position to drive the fertilizer application apparatus, [I] ] When the fertilizer applicator is moved from the working position to the non-working position as described above, it is necessary to disconnect the transmission system from the output section to the input section of the fertilizer applicator. In this case, if the transmission chain is wound around the output section and the input section of the fertilizer applicator, or if the bevel gear mechanism and the transmission shaft are installed, the transmission chain and the transmission shaft can be removed in order to configure the transmission chain. A complicated attachment / detachment structure is required, and this complicated attachment / detachment structure causes an increase in weight.

According to the feature of claim 1, the drive rod is connected between the output part and the input part of the fertilizer application device, and the power of the output part is transmitted to the input part of the fertilizer application as push-pull power by the drive rod. With this configuration, the drive rod can be simply removed to obtain a structure for disconnecting the connection between the output unit and the input unit by the drive rod.

[III] When disconnecting one or the other of the drive rods, if the connection between one of the drive rods and the input section of the fertilizer application can be released, one of the drive rods and the input section of the fertilizer application can be released. When the power is mistakenly output from the output section when the other drive rod is connected to the output section, the long drive rod is swayed while being pushed and pulled. As a result, the drive rod or the like may be damaged.

When the connection between the other side of the drive rod and the output section is releasable as in the first aspect of the present invention, when the connection between the other side of the drive rod and the output section is released, the power is erroneously output from the output section. Is output, the drive rod is separated from the output portion, so that the drive rod is not pushed and pulled and swung.

[IV] According to the feature of claim 1, one of the drive rods is connectable to the input part of the fertilizer applicator, and the other of the drive rods is connectable to and disconnectable from the output part.
As a result, when the connection between the other side of the drive rod and the output section is released, one side of the drive rod is connected to the input section of the fertilizer applicator and becomes stable in the state of hanging downward due to its own weight. It is not necessary to provide a dedicated member or the like for holding the drive rod in the non-working position of the device.

[V] In the feature of claim 1, at the working position of the fertilizer application, the other side of the drive rod is connected to the output portion only along a direction intersecting the moving direction of the fertilizer application between the working position and the non-working position. And configured to be able to disconnect.
As a result, it is necessary to move the fertilizer application from the working position to the non-working position after disconnecting the connection between the other side of the drive rod and the output section at the working position, and the other side of the drive rod was connected to the output section. In this state, the fertilizer applying device cannot be moved from the working position to the non-working position (based on the fact that the direction of disconnecting the drive rod and the moving direction of the fertilizer applying device intersect).

Therefore, when the operator tries to move the fertilizer application from the working position to the non-working position without disconnecting the other side of the drive rod from the output part, the fertilizer applying device is moved to the non-working position. Due to the inability, the operator will notice that the other side of the drive rod and the output part are not disconnected.

[VI] According to the characteristics of claim 2, the "action" described in [I] to [V] is the same as in the case of claim 1.
In addition to this, the following "action" is provided. According to the feature of claim 2, the output part is arranged below the fertilizer application device at the working position. As a result, when the fertilizer applicator is moved from the non-working position to the working position in the state where the connection between the other of the drive rods and the output section is released, as described above, the other of the drive rods hanging downwards, Since it will automatically reach the vicinity of the lower output part, the other of the drive rods can be connected to the output part by moving the fertilizer application device in a direction intersecting the moving direction of the fertilizer application device. In this case, the drive rod hanging downward is simply swung with the input part of the upper fertilizer application as a fulcrum, and the other of the drive rods moves in the direction intersecting the moving direction of the fertilizer application. The other side of the drive rod can be easily connected to the output section without complicated operations.

[0015]

According to the first aspect of the present invention, in a rice transplanter with a fertilizer application, the fertilizer application can be moved to a non-working position apart from the working position, so that the fertilizer applying device can be arranged near the fertilizer applying device and the working position. It has become possible to easily perform maintenance work for other devices that have been used, and the workability of a rice transplanter with a fertilizer application can be improved. When moving the fertilizer application between the working position and the non-working position, the fertilizer in the fertilizer application does not spill, so there is no need to take out the fertilizer from the fertilizer application for the moving operation. Also, there is no waste of the fertilizer, and the spilled fertilizer is prevented from being rusted due to being attached to the metal part.

As in the first aspect of the present invention, by connecting the output part and the input part of the fertilizer application by a push-pull type drive rod, the drive rod can be simply disconnected. Thus, the structure for releasing the connection between the output portion and the input portion by the drive rod can be configured to be simple, which is advantageous in terms of weight reduction. Further, since the operation of releasing the connected state and the operation of returning to the connected state again can be easily performed, the operability is improved. By making the connection between the drive rod and the output unit releasable, the drive rod is prevented from being swung around while being pushed and pulled, and damage to the drive rod and the like can be prevented in advance.

According to the feature of claim 1, one of the drive rods is connected to the input part of the fertilizer application, and the other of the drive rods is connectable to and disconnectable from the output part. Since it stabilizes in the state of hanging downward, it is not necessary to provide a dedicated member or the like for holding the drive rod in the non-working position of the fertilizer applicator, which is advantageous in terms of simplification of the structure.

According to the first aspect of the present invention, the drive rod can be connected to and disconnected from the output portion only along the direction intersecting the moving direction of the fertilizer application between the working position and the non-working position. Since an erroneous operation of moving the fertilizer applicator from the working position to the non-working position can be prevented without disconnecting the drive rod and the output unit, problems such as damage due to such erroneous operation can be prevented. Avoided.

According to the feature of claim 2, as in the case of claim 1, the "effect of the invention" of claim 1 is provided. When the fertilizer applicator is moved from the non-working position to the work position by arranging the output section below the fertilizer applicator in the working position, the driving rod hanging downward is moved downward. The operability is further improved due to the fact that the drive rod is easily reached in the vicinity of the output portion and that the drive rod can be easily connected to the output portion by shaking the drive rod thereafter.
