Description

[Detailed Description of the Invention] The present invention relates to a device for sowing seeds in paddy fields that have been plowed and for spraying chemicals on the rice fields.

Generally, when a device for spraying chemicals on the ground surface is attached to a seeding device, the seeding device sows the seeds in the grooved area and then covers the soil, so it is better to spread the chemicals before sowing to obtain the desired medicinal effect. I can't.

Therefore, conventionally, as described in Japanese Utility Model Publication No. 40-31078, a seeding machine was placed at the front, and a chemical spraying device was provided at the rear.

However, when the above-mentioned known method is applied to a flooded seeding machine, since the field surface is uneven, the seeding tube of the seeding device must face the rear of the float for leveling the field. If a spraying device is provided on the machine, the fuselage becomes longer and the front-to-back balance worsens, resulting in instability.

The purpose of this invention is to improve the above-mentioned drawbacks by attaching a machine frame to the body of a traveling vehicle.
A float is attached to the lower part of the machine frame, a chemical spraying device for spraying surface-sprayed chemicals such as herbicides is provided at the front of the machine frame, and a seeding device is provided at the rear of the chemical spraying device. , a pair of seeding tubes are suspended from both sides of the seeding device, and a groove-making body is provided in the front part of the seeding tubes,
A soil covering plate is provided at the rear, and a spreading chute protruding from the chemical spraying device extends rearward from between the pair of seeding tubes, and its discharge port faces the ground behind the soil covering plate. This is a characteristic feature.

The embodiments shown in the drawings will be explained below.
1 is a machine body having front wheels 2, 2 and rear wheels 4, 4 which are pivotally supported at the rear of swing chain cases 3, 3, and a mounting frame 5 can be raised and lowered at the rear by means of a top link 6a and a lower link 6b, 6b. It is installed.

The front frame 7 is fixed to the lower part of the mounting frame 5.
As shown in Fig. 2, both ends of the machine are connected by vertical frames 7a, 7a to a horizontal frame 8 extending to both left and right sides, and three machine frames 9 are attached to the horizontal frame 8 in the center and on the left and right sides. A float 10 with a wide front part and concave parts on both sides of the rear part is attached to each machine frame 9 downward by a spindle 11 and a link 12, and two feed rolls 1 are attached to the upper part.
A seeding device 14 having rollers 3 and 13 is installed at the rear, and a spreading device 16 having feed rolls 15 and 15 is installed at the front.

Moreover, the feeding roll 1 of each of the seeding devices 14...
The roll shafts 17 . The output sprocket 21 of the gear case 20 provided above is driven via a chain 22, and the sprocket 24 of the roll shaft 23 of each spreading device 16 is driven by the other sprocket 26 of the roll shaft 17 via a chain 25, An input shaft 27 extending forward from the gear case 20 is connected via a universal joint 29 to a diagonal shaft 28 that interlocks with the PTO shaft of the fuselage 1 .

Furthermore, a pair of left and right seeding pipes 30, 30 are vertically installed on both sides of the rear of the seeding device 14, the upper part of which communicates with the delivery rolls 13, 13, and the lower part of which faces the recesses on both sides of the rear of the float 10. Spreading chutes 31, 31, whose front portions communicate with the feed rolls 15, 15 of the spreading device 16, pass between the seeding pipes 30, 30 and extend toward the rice fields at the rear, as shown in FIG. ing.

32 is a groove-forming body with an open concave portion, and 33 is a seeding pipe 3.
0.30, and a soil cover plate 34 is provided at the rear of the funnel.

In the above-mentioned device, seed rice coated with an oxygen generating agent is put into the tank part 14a of the seeding device 14, and a herbicide is put into the tank part 16a of the spreading device 16, and then the machine 1 is moved while driving the input shaft 27 with the PTO shaft. When the feed rolls 13, 13 move forward, the rice seeds fed out by the feed rolls 13, 13 pass through the seeding pipes 30, 30, and reach the groove forming body 3.
2 falls into the groove formed, the soil covering plates 34, 34 cover the seed rice, and the feed rolls 15, 1 of the spreading device 16
The herbicide fed out by No. 5 is widely spread over the soil-covered rice field in the rear through the spraying chute 31, 31.

During such seeding and spreading work, seeds can be sown on the leveled rice field at the rear of the wide part of the float 10 using the seeding device 14, and the seeding device 16 in the center
Since the seeding device 14 is placed close to the rear surface of the spreading device 16 while the seeding device 14 is connected to the front frame 7, both devices 1
4 and 16 near the front of the float 10 and the mounting frame 5
can be placed closest to the

Next, to explain another example of the transmission device, the roll shaft 23 of the spreading device 16 is also connected to the connecting pipes 18, 18 in the same way as the roll shaft 17 of the seeding device 14.
If another sprocket is attached to the output shaft of the gear case 20, and this sprocket drives the roll shaft 23 of the central spreading device 16 through another chain, the three sets of sprockets 24 in the above-described embodiment can be connected. , 26 and the chain 25 can be omitted, and the strength of the chain 22 can be weakened.

As mentioned above, the present invention is a chemical spraying device that attaches a machine frame to the body of a traveling vehicle, attaches a float to the lower part of the machine frame, and sprays surface-sprayed chemicals such as herbicides on the front part of the machine frame. A seeding device is installed at the rear of the chemical spraying device, a pair of seeding tubes are suspended from both sides of the seeding device, a trench-making body is provided at the front of the seeding tube, and a soil covering plate is installed at the rear. The spraying chute protruding from the chemical spraying device is extended rearward from between the pair of seeding tubes, and its discharge port faces the ground behind the soil covering plate, so that the sowing position by the seeding device can be controlled. Although the float can be placed over a leveled rice field, by installing the spreading device at the front of the seeding device, these devices can be brought closer to the traveling vehicle, shortening the length of the machine and making it easier to steer. It is possible to improve the performance and stability of the aircraft.

In addition, although the spreading device is installed at the front of the seeding device, the spreading chute extends backwards from between the left and right seeding tubes, making it possible to accurately spread the chemical onto the field after seeding. .

Furthermore, the seeds sown in the grooves formed by the trench cutting body are covered with soil by the soil covering plate, and the chemicals discharged from the spreading chute are spread on the flat soil surface leveled by the soil covering plate, and the seeds are covered with soil by the soil covering plate. Accuracy can be improved, and the position where germination can be reliably treated with a herbicide or the like.
