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 directly seeding rice fields that have been plowed and spraying chemicals, if the chemicals are applied first, footprints will be left on the rice fields, which cannot be removed even by leveling them with floats. They were careful not to step on the sowing area as they spread the seeds.

The present invention is capable of simultaneously sowing seeds and spraying chemicals on the plowed rice field with high efficiency, and is capable of reliably spraying chemicals on the upper surface of the sown area without causing clogging. A direct sowing machine is provided, in which a float is attached to the lower part of the machine frame, and a seeding device is installed at the front of the machine frame,
A chemical spraying device is provided at the rear, and a pair of left and right feeding rolls is pivotally supported in each tank portion of these devices, and each spraying chute hanging down from the feeding portion of the chemical spreading device is connected to each seeding pipe of the seeding device. It is characterized by being placed immediately after.

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 to a horizontal frame 8 extending to the left and right sides by vertical frames 7a, 7a, and three machine frames 9 are attached to the horizontal frame 8 in the center and on the left and right sides. Each machine frame 9 is equipped with a float 10 having a wide front part and recessed parts at the rear part at the bottom by a spindle 11 and a link 12, and a pair of left and right feeding rolls 13, 13 at the top. The device 14 is installed at the front, and the spreading device 16 having a pair of left and right feed rolls 15, 15 is installed at the rear.

Moreover, the feeding roll 1 of each of the seeding devices 14...
The roll shafts 17 of 3 and 13 are arranged in a straight line and connected by detachable connecting pipes 18 and 18, and the roll shaft 17 of the central seeding device 14
The sprocket 19 attached to the machine frame 9 below
Output sprocket 2 of gear case 20 provided above
1 through a chain 22, each spreading device 1
The sprocket 24 of the roll shaft 23 of No. 6 is connected to the chain 2
5 to the sprocket 26 of the roll shaft 17
An input shaft 27 that is driven by and extends forward from the gear case 20 is connected via a universal joint 29 to an oblique 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 disposed on both rear sides of the seeding device 14, the upper portions of which communicate with the feed rolls 13, 13, and the lower portions of which face the recesses on both rear sides of the float 10. A pair of left and right spreading chutes 31, 31 whose upper portions are connected to the feed rolls 15, 15 of the spreading device 16 are suspended immediately after the seeding tubes 30, 30 so as to substantially overlap when viewed from the front and rear directions.

32 is a groove forming body fixed to the lower surface of the float 10;
33 is a funnel facing directly below the seeding pipes 30, 30, and a soil covering plate 34 is provided at the rear thereof.

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 directly above the sowing area through the spraying chute 31, 31.

During such seeding and spreading work, the seeding chute 3
1 and 31 are not curved laterally when viewed from the front and rear directions, so there is no possibility of clogging or uneven spraying amount on the left and right sides.

Next, to explain another example of the transmission device, the roll shaft 23 of the spreading device 16 is also connected to the roll shaft 17 of the seeding device 14 with connecting pipes 18, 8, and another one is connected to the output shaft of the gear case 20. Either a separate sprocket is installed on the roll shaft 17 of the seeding device 14 and the roll shaft 23 of the central spreading device 16 is driven by this sprocket via a separate chain, or another sprocket is installed on the roll shaft 17 of the seeding device 14 and the roll shaft 23 of the spreading device 16 is driven by this sprocket. are connected by the connecting pipes 18, 18 as described above, and then a sprocket is attached, and a chain is stretched between this sprocket and the other sprocket, and the three sets of sprockets 24, 26 and chain 25 in the above-mentioned embodiment are connected. Two of them can be omitted.

FIG. 5 shows the delivery rolls 15, 15 of the spreading device 16.
The central part is provided, and the lower part is expanded into a flap shape so that the lower end opening extends from the rear of one seeding tube 30 to the rear of the other seeding tube 30 when viewed from the rear. Diagonal grooves are carved on the circumferential surfaces of 15, 15 so as to scrape out the medicine outward.

As mentioned above, the present invention has a float installed at the bottom of the machine frame, a seeding device at the front of the machine frame, a chemical spraying device at the rear, and a pair of left and right feeding rolls in each tank of these devices. Since each of the spraying chute, which is pivotably supported and suspended from the feeding part of the chemical spraying device, is placed immediately after each seeding tube of the seeding device, the seeding device sows the seeds in advance of the spreading device,
At the same time as this sowing, immediately after the seeding, the spreading device spreads the chemical onto the sowing area, so there are no footprints left on the sowing area, and the seeds can be sown at an appropriate depth with high efficiency. .

In addition, since the spreading chute hangs down immediately after the seeding tube, the amount of spreading does not become uneven from side to side, unlike when it is bent laterally, and it can be applied evenly to the rice field directly above the sown area. I can do it.
