Description

[Detailed Description of the Invention] The present invention relates to a rice transplanter with a fertilization device equipped with a groove creator for forming fertilization grooves on a mud surface.

In such a rice transplanter, the fertilization groove after fertilizer is supplied is backfilled in order to prevent the fertilizer from unexpectedly flowing out of the groove. Conventionally, as disclosed in Japanese Utility Model Application Publication No. 57-125213,
The bottom of the float is equipped with a protrusion that pushes the mud toward the fertilization groove after fertilizer is supplied as the vehicle advances.In this case, in order to ensure sufficient backfilling, the The mud pressing protrusion has to protrude considerably downward from the float, and as a result, there is an inconvenience that a large amount of resistance is given to the vehicle body movement due to the backfilling of the ditch. After cutting and backfilling, the backfilled mud would collapse and flow into the cut groove, causing fertilizer to flow out, making it difficult to put into practical use.

The present invention was devised in view of the above-mentioned circumstances, and its purpose is to create a fertilizing groove in a rice transplanter while suppressing an increase in vehicle movement resistance by simply modifying the soil leveling float provided in the rice transplanter. The purpose is to properly backfill the soil and suppress fertilizer runoff.

The characteristic configuration of the present invention is that, in the above-mentioned rice transplanter with fertilization device, a groove for mud flow is provided at the bottom of the soil leveling float.
The inlet faces toward the front of the vehicle body, and the outlet faces toward the side of the float so as to flow mud to the fertilization groove side after fertilizer is supplied, and
The point is that the side part of the float after the exit is extended rearward in a straight line.

Next, the effects of the feature configuration of the present invention will be described.

In other words, as the vehicle moves forward, the mud that enters the mud flowing groove formed at the bottom of the float is allowed to flow toward the fertilizing groove after fertilizer is supplied, thereby making it possible to backfill the fertilizing groove. I have made it possible.

Therefore, the desired backfilling is carried out by the flow of mud through the mud-flowing groove as the car body advances, so there is less resistance to the car body movement compared to the conventional means of forcing mud to flow toward the fertilization groove. This allows backfilling to be carried out with less fertilizer application, and also prevents the backfilling mud, which is guided into the fertilizer application trench by the mud flow trench, from escaping laterally. The long float side allows for good backfilling and prevents fertilizer from flowing out.
Overall, a rice transplanter with a fertilization device that can be used more conveniently has been obtained.

Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in FIG. 1, a pair of left and right front steering wheels 1, 1 and a pair of left and right rear wheels 2, 2 are provided so as to be freely drivable, and an engine 3 is installed at the front of the vehicle body.
In addition, a driver's seat 4 is provided at the rear of the vehicle body to form a passenger vehicle body, and a float 7 is operated by a planting claw 6 that sequentially takes out seedlings one by one from a seedling platform 5.
Seedling planting device 8 for planting seedlings on the leveled mud surface
is connected to the rear part of the passenger vehicle body by a hydraulic cylinder 9 so that it can be raised and lowered freely, and further, the powdery fertilizer supplied from the main tank 10 provided at the front part of the passenger vehicle body is applied to the side of the planted seedlings W. A fertilizer application device 11 is provided on the side of the rice transplanter, thereby constructing a rice transplanter equipped with a fertilizer application device that performs fertilization while planting seedlings as the vehicle moves forward.

To explain the fertilizer application device 11, as shown in FIGS. 1 to 3, it has a boat-like shape in plan view,
In addition, a groove making device 12 which doubles as a fertilizer release guide and has an open bottom and rear part is fitted and supported on the bottom of the float 7, so that the fertilizing groove U corresponds to the lateral side of the planted seedlings W. A sub-tank 15 is supported on the seedling planting device 8, and is equipped with a rotary body 14 that feeds out the stored fertilizer in fixed quantities toward the supply pipe 13 connected to the trencher 12. At the same time, a mud flow groove 16 is provided at the bottom of the soil leveling float 7 so that its inlet 17 faces the front of the vehicle body, and its outlet 18 is installed on the side of the float so that the mud flows toward the fertilization groove U after fertilizer is supplied. A fertilization groove U formed in a sideward direction and then formed by a groove creator 12
In addition, the side part of the float after the outlet is extended rearward in a straight line so that the backfilling mud discharged from the outlet can be supplied with fertilizer sequentially.
The long rear side surface of the float restricts the fertilizer from escaping laterally, so that the fertilizer application groove U can be backfilled after the fertilizer has been supplied.

In order to supply fertilizer from the main tank 10 to the sub-tank 15, a flexible hose 19 that connects both tanks 10 and 11 is provided so as to bypass the upper part of the sunshade cover 20 that covers the upper part of the driver's seat 4. In the hose 19, a feeder 21 made of a wire bent in a spiral shape is provided. Then, on the input shaft 21A for driving rotation of the spiral feeder 21,
The input pulley 2 is belt-transmitted to the engine 3.
2 is attached so as to be switchable between an integral rotation state and a relative rotation state via an electromagnetic clutch 23, and the electromagnetic clutch 23 is connected to a first sensor for detecting when the amount of fertilizer in the sub-tank 15 has fallen below a set amount. A second sensor 24 is operated based on the information of the sub-tank 15 and detects when the amount of fertilizer in the sub-tank 15 exceeds a set amount.
provided so that the cutting operation is performed based on the information of b.
In addition, the structure is such that the fertilizer in the main tank 10 can be automatically replenished into the sub tank 15.

Next, another example will be described.

4 and 5, an auxiliary mud flow groove 25 for discharging excess mud to the rear of the float is formed at the bottom of the float so as to communicate with the mud flow groove 25. And mud flow groove 16
A pair of vertical walls 16 in the front and rear of the outlet 18 side gutter portion
A and 16b are constructed such that the lower end side corners of each of them are arcuate to facilitate molding, for example, by blow molding the float 7. In that case, by making the radius of curvature of the rear vertical wall 16b smaller than the radius of curvature of the front vertical wall 16a, it is possible to prevent mud from accidentally flowing out to the rear of the vehicle body. good.

6 and 7 show a pair of vertical walls 16a, 16 at the front and rear of the outlet 18 side groove portion of the mud flow groove 16.
b, the vertical wall 16a on the front side is formed into an inclined surface shape such that the lower side is located toward the front of the vehicle body.

FIGS. 8 and 9 show an upper wall 16c of the outlet 18 in the mud flow groove 16.
is formed into an inclined surface that is located lower toward the outlet 18 so that the speed of mud flowing out at the outlet 18 becomes faster.

In the above embodiment, the case where seedlings are planted on both lateral sides of the float 7 is illustrated. However, in the case where seedlings are planted only on one lateral side of the float 7, the outlet 18 is connected to either the left or right side. Of course, it is sufficient to form a mud flow groove 16 in preparation for this.

Furthermore, when providing the furrower 12, instead of supporting it on the float 7, it may be directly supported by the seedling planting device 8, or the furrower 12 may not be used also as a fertilizer release guide. You may.
