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.

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 to the field along with the planting of seedlings, and extends over the working position for feeding the fertilizer into the field and the non-working position away from the working position. And a holding means for holding the fertilizer application in the non-working position by preventing the fertilizer application from moving toward the working position.

And holding means for holding the fertilizer application in the non-working position while movably supporting it while maintaining the posture at the work position and preventing the fertilizer application from moving toward the work position. .

[3] A guide member arranged vertically is provided, and a support member having a pair of upper and lower guide rollers is provided, and the support member is supported by the guide roller so as to be movable along the guide member. , The fertilizer application that feeds the fertilizer to multiple rows of the field along with the planting of seedlings is connected and supported by the support member, and the fertilizer application is separated from the lower working position and the upper working position for sending the fertilizer to the field. The non-working position can be movably supported while maintaining the posture at the working position, and the fertilizer application device can be held at the working position and the non-working position between the upper and lower guide rollers of the supporting member. A holding means is provided.

[0007]

[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 applying device is moved between the working position and the non-working position, the fertilizer applying device can be moved while maintaining the posture at the working position. Therefore, when the fertilizer applying device is moved and operated. 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.

When the fertilizer applying device is moved from the working position to the non-working position, the fertilizer applying device may be held at the non-working position by the holding means. As a result, while the fertilizer application device is stably held in the non-working position, the maintenance work of the fertilizer application device and the maintenance work of other devices located near the work position can be performed.

[II] According to the characteristics of claim 2, as in the case of claim 1, the "action" described in the above [I] is provided, and in addition to this, the following "action" is provided. ing. According to the feature of claim 2, since the fertilizer application device can be moved in the vertical direction between the lower working position and the upper non-working position, the fertilizer application can be performed from the range of the rice transplanter with the fertilizer applying device by the moving operation to the non-working position. The device does not come out large in the lateral direction. As a result, even in a relatively narrow place such as a barn, the fertilizer application device can be moved to the upper non-working position without any trouble.

[III] According to the characteristics of claim 3, as in the case of claims 1 and 2, the "action" described in the above [I] and [II] is provided. It has the "action". According to the feature of claim 3, the fertilizer applying device is supported by the support member so as to be movable along the guide member between the lower working position and the upper non-working position. In this case, since the pair of upper and lower guide rollers provided on the support member are arranged in the moving direction of the support member (the vertical direction along the guide member), the guide roller moves up and down when the fertilizer applying device is moved along the guide member. The support action of the pair of guide rollers prevents the support member from tilting to the other side with respect to the guide member along the movement direction. As a result, a state in which the support member tilts to the one side and the other side with respect to the guide member with respect to the movement direction and the movement of the support member along the guide member is not smoothly performed (a so-called twist phenomenon) Does not happen.

When the fertilizer applicator is moved from the working position to the non-working position, if the fertilizer applicator is held at the non-working position by the holding means, the fertilizer applicator is stabilized at the non-working position as in the first and second embodiments. In this state, the maintenance work of the fertilizer application and the maintenance work of other devices arranged near the work position can be performed. Further, according to the feature of claim 3, when the fertilizer applying device is moved from the non-working position to the working position, the holding device can hold the fertilizer applying device at the working position. As a result, the fertilizer is fed from the fertilizer application to a plurality of rows in the field while the fertilizer application is stably held at the work position.

When the support member tilts to one side and the other side along the moving direction with respect to the guide member, there may occur a state in which the fertilizer application cannot be properly held in the working position and the non-working position by the holding means. According to the feature of claim 3, as described above, the pair of upper and lower guide rollers prevents the support member from tilting toward the other side with respect to the guide member in the moving direction. Further, since the holding means is provided between the upper and lower guide rollers that are minimally displaced even if the support member is inclined, the holding means can reliably hold the fertilizer application at the working position and the non-working position.

[0014]

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. Since the fertilizer applicator can be held in the non-working position, maintenance work of the above-mentioned fertilizer applicator and other devices located near the work position can be performed while the fertilizer applicator is stably held in the non-working position. Since it can be reliably performed, the workability of the rice transplanter with the fertilizer application can be further improved.

According to the feature of claim 2, as in the case of claim 1, the above-mentioned "effect of the invention" is provided. According to the feature of claim 2, the fertilizer application device is configured to be movable in the vertical direction between the lower work position and the upper non-work position, so that the fertilizer application device can be used even in a relatively narrow place such as a barn. Can be moved to the non-working position without hindrance, and the workability of the rice transplanter with the fertilizer application can be further improved.

[0016] According to the features of claim 3, claims 1 and 2 are provided.
Similar to the above case, the "effect of the invention" of the above-mentioned claims 1 and 2
It has. According to the third aspect of the present invention, the guide member, the support member, and the pair of upper and lower guide rollers enable the fertilizer application device to be smoothly moved and operated without causing a twisting phenomenon, resulting in good operability. Since the fertilizer application can be held in the working position and the non-working position, while the fertilizer applying device is stably held in the working position and the non-working position, the fertilizer is sent to the field, and the fertilizer applying device and the work position are close to each other. It becomes possible to reliably perform the maintenance work of the other devices arranged, and it is possible to further improve the workability of the rice transplanter with the fertilizer application device. The pair of upper and lower guide rollers prevent the support member from tilting to one side and the other side along the moving direction with respect to the guide member, and between the upper and lower guide rollers with the least displacement even if the support member tilts. Since the holding device is provided with the holding means, the holding device can securely hold the fertilizer application at the working position and the non-working position, and the workability of the rice transplanter with the fertilizer application can be further improved.
