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, which has three or more planting mechanisms and is provided with a fertilizer application device for each.

[0002]

2. Description of the Related Art In a rice transplanter with a fertilizer application device of this type, the hopper for the fertilizer application device may be arranged, for example, in Japanese Utility Model Publication 59-.
In the one disclosed in Japanese Patent No. 77318, hoppers for two threads are arranged side by side on the lateral outside of the machine body and in the front-rear direction of the machine body.

[0003]

Therefore, in such a case, the fertilizer from the hopper located on the rear side is applied to the inner planting line and the fertilizer from the hopper located on the front side is placed on the outer planting line. It is better to apply to both the hopper and the fertilizer ditch because it is possible to minimize the flow-down path from the hopper to the fertilizer ditch, but nevertheless, the intermediate position of the hopper in the machine longitudinal direction is set as the fertilizer position (groover). Even if the flow-down paths are arranged so as to be substantially equal, since the feeding mechanisms are displaced forward and backward from the fertilizer application position, the flow-down paths are longer than when the hopper (feeding mechanism) is located directly above the fertilizer application position. Inevitably, there was a situation where clogging in the downflow route was likely to occur. An object of the present invention is to provide a hopper having a less clogging in the flow-down path, and to provide a reasonable instruction structure for the hopper.

[0004]

A characteristic configuration according to the present invention is that the center hopper and the left and right side hoppers are arranged laterally outward of the left and right propulsion wheels in the center of the machine body to provide a fertilizer hopper group, and The side hopper is attached to a support member that is provided over a fulcrum portion of each of the vehicle body, that is, a base end portion of a wheel transmission case that pivotally supports the wheel and is vertically swingable, and a side float located laterally outside the wheel. Is attached, and its action and effect are as follows.

[Operation] (a) Due to the characteristic configuration, by disposing the hoppers along the lateral width direction of the vehicle body corresponding to the plurality of planting strips provided along the lateral width direction of the vehicle body, the hoppers are arranged in the middle of the lateral width direction of the vehicle body. Fertilization is applied from the center hopper to the planting strips located, and from the side hopper to the outer planting strips located laterally outward of the propulsion wheels. It can have the same length and the shortest path. (B) Moreover, even if the center hopper supported by the airframe is good, the side hoppers located on the lateral outer side of the propulsion wheels and the side floats and wheels that are necessarily located near the propulsion wheels due to the characteristic configuration are The side hopper is supported by this support member by installing a support member that effectively utilizes the fulcrum part with the transmission case. Therefore, even if this support member is installed, it can be provided at the fulcrum portion of the wheel transmission case closer to the side hopper side or side float as compared with the case where this support member is fixed to the mission case or transmission case on the machine side. The length of the support member can be shortened, and this support member can be set at a low position along the height of the float, so the installation position of the side hopper can be set to the lowest position possible and the length of the downflow path can be shortened it can.

[Effect] As a result, the downflow path can be suppressed to the required minimum length, the fertilizer clogging in the downflow path can be suppressed, and a rational support structure corresponding to the installation position of the side hopper can be constructed. Came to.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a walk-behind rice transplanter equipped with a fertilizer application device, and more particularly to a walk-behind rice transplanter provided with a fertilizer application device having a preliminary seedling stand on the hood of the machine body.

[0002]

2. Description of the Related Art In this type of walk-behind rice transplanter equipped with a fertilizer application, both of the seedlings and fertilizer must be installed near the grounding point of the wheels in order to mount them in a state where they are less affected by their quantitative changes. is there. Therefore, conventionally, the following [1], [2]
The one with the structure as shown in was adopted. [1] A spare seedling stand was placed along the bonnet, and a fertilizer hopper was attached and supported on the lateral outer side of the spare seedling stand, and a feeding mechanism connected to the lower part of this hopper was used to feed it through a downflow hose. The fertilizer is configured to flow down and be guided to a grooving device provided near the seedling planting site (see, for example, Japanese Utility Model Laid-Open No. 60-114624). [2] A fertilizer application hopper is installed on the machine body frame, and a lid that covers the upper opening of the hopper is configured so that a preliminary seedling can be mounted to form a preliminary seedling placing part (Actual No. 57-138512). Gazette).

[0003]

According to the conventional structure described in the above [1], the fertilizer application hoppers are arranged on the left and right sides of the machine body, so that the interference with the traveling wheels located on the left and right sides of the machine body is avoided. In order to do so, it is necessary to install a fertilizer application hopper at a high position, and a large amount of fertilizer is stored, and the center of gravity of the hopper, which is relatively heavy, is at a high position, and when the control handle is moved up and down when operating the aircraft, There is a drawback that the center of gravity moves back and forth and it becomes difficult to perform a steering operation, and since the hoppers project upwards on both left and right sides of the preliminary seedling stand, seedling supply work for this preliminary seedling stand is possible. There was also a drawback that it was hindered by this hopper, making it difficult to carry out seedling supply work. Further, in the conventional structure described in the above [2], since the preliminary seedling placing portion is above the fertilizer hopper, the seedlings are taken out from the preliminary seedling placing portion,
In addition, it is possible to prevent the supply of seedlings to the reserve seedling placement part from being hindered by the fertilizer hopper. Inconvenient work is forced. In addition, when replenishing seedlings from the preliminary seedling placement part, which must be performed relatively frequently, to the seedling rest of the seedling planting equipment, the preliminary seedling placement part is located far from the control part, so mud must be supplied each time seedling supply. There was the inconvenience of having to walk inside and move to the position of the spare seedling mounting table, and further, because heavy seedlings were loaded, the strength of the fertilizer hopper itself had to be increased. The object of the present invention is to take out and replenish the preliminary seedlings on the preliminary seedling stand and to replenish the fertilizer to the fertilizer hopper without causing the machine to become too high in center of gravity or the state where the operation of supplying the seedlings from the control section is difficult. The point is to provide a walk-behind rice transplanter with a fertilizer application that makes it easy to perform.

[0004]

Means for Solving the Problems The technical means of the present invention taken to achieve the above object is to dispose a fertilizer application device at a position near the ground contact point of a propelling wheel and to provide a fertilizer application hopper for the fertilizer application device. A fixed rail is provided along the front-rear direction of the machine body, and on this fixed rail, a preliminary seedling is slidably movable back and forth over a position located above the fertilizer application hopper and a position where the upper part of the fertilizer application hopper is opened. It was the support of the stand.

[Operation] The operation by taking the above technical means is as follows. (A) By arranging the fertilizer application near the grounding point of the propulsion wheels, the center of gravity of the fertilizer application, which stores fertilizer and is relatively heavy, moves in the machine longitudinal direction even when the machine moves up and down. It does not change so much and it is easy to avoid a change in the front-rear balance of the aircraft. Moreover, even if the weight in the hopper changes due to the consumption of fertilizer, its center of gravity is near the grounding point of the wheel, so that there is little change in the front-rear weight balance of the aircraft also at this point. (B) In addition, since the preliminary seedling stand is arranged above the fertilizer application device, there is no member protruding above the preliminary seedling stand so that the seedlings can be easily supplied and seedlings are being planted. By placing this spare seedling stand above the fertilizer applicator, its center of gravity is located above and below the grounding point of the wheel, similar to the fertilizer applicator. Regardless of the change, the change in the front-rear weight balance of the aircraft will be small. (C) And, as a result of arranging the preliminary seedling stand above the fertilizer application device, the drawback that the fertilizer supply work to the fertilizer application device becomes difficult is solved by making the preliminary seedling stand slidable back and forth. However, during the fertilizer replenishment work, the auxiliary seedling stand is slid to a position where the upper part of the fertilizer application hopper is opened, so that the upper part of the hopper is opened and it can be easily performed.

[Effect] Therefore, the preliminary seedling stand and the fertilizer application device whose weight changes according to the work situation are integrated near the ground contact point of the propulsion wheels where it is difficult to adversely affect the weight balance between the front and rear of the machine. Although it is possible to improve the maneuverability by arranging it in a special manner, it is possible to obtain a working mode in a state where it is easy to supply the spare seedlings and fertilizers by sliding the spare seedling mounting table. It is possible to prevent the workability of the above-mentioned replenishment work from being deteriorated by the intensive arrangement of the preliminary seedling placing table and the fertilizer application device. Moreover,
If the auxiliary seedling stand is slid to the open position when replenishing fertilizer, there will be a slide support rail for the auxiliary seedling stand on the upper lateral side of the hopper. Therefore, it is possible to perform the replenishment work while receiving and supporting the weight. Therefore, it is not necessary to perform the replenishment work while lifting the heavy fertilizer bag, and there is also an advantage that the fertilizer replenishment work can be performed in a comfortable posture by allowing the slide support rail to share the weight of the fertilizer bag.
