Reference numeral 4 denotes two tanks, each having three feeding mechanisms 5. One feeding mechanism 5 is connected to two nozzles 2. The objects to be sprayed in the tanks 4 are sprayed from the nozzles 2 to perform wide spraying. By changing the shape of the nozzle, the seeding can be done freely.

In such a sprayer, the tank 4 is configured as shown in FIG. The tank 4 is partitioned by a partition wall 6 to form two tank chambers 4A and 4B, each of which is provided with three drop ports 4a and 4b. The drop ports 4a and 4b are arranged side by side along the axial direction of a roll shaft (described later) of each of the feeding mechanisms 5.

If fertilizer and seed, pesticide (herbicide) and seed, and pesticide (herbicide) and fertilizer are put in the tank rooms 4A and 4B, respectively, these can be sprayed at the same time, and the spraying time is halved. On the contrary, it is not necessary to go back and forth in the field many times, and there is no need to step on the field. that time,
When throwing the scattered material into the tank chamber 4A or 4B, it is not necessary to throw the scattered material into each of the three drop openings 4a or 4b, and the three fall ports 4a or 4b are not required.
Since the spreadable materials can be collectively input to the tank, the work of inputting the spreadable materials to the tank can be saved. Although not shown, the inside of the tank 4 may of course be divided into a plurality of tank chambers by a plurality of partition walls 6.

Embodiment 2 FIG . One embodiment of the second aspect of the present invention will be described with reference to FIGS. Figure 3 shows one of the tanks with three drops

FIG. 5 is a cross-sectional view taken along a line V. The same portions as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

In the drawing, reference numeral 7 denotes a case of a feeding mechanism 5 connected to each of the drop ports 4a and 4b of the tank chambers 4A and 4B.
An upper portion has a partition wall 7a that is continuous with the partition wall 6 of the tank 4 and side lids 8 on the left and right. Reference numeral 9 denotes a spray passage connected to the outlet 7b of the case 7, and is blown in the direction of the arrow. A roll shaft 10 is rotatably and axially slidably inserted into the lids 8 on both sides, and is rotatably driven by a motor (not shown). Reference numeral 11 denotes a fork guide for sliding the roll shaft 10, and 12, 13, and 14 denote three feed rolls which are rotatably juxtaposed on the roll shaft 10 and have different feed amounts. The feed roll 12 has a large feed amount. ,
The feeding roll 13 has a smaller length in the axial direction than the feeding roll 12 to reduce the feeding amount, and the feeding roll 14 has a significantly different shape from the two feeding rolls 12 and 13 so that the feeding amount is small. Reference numeral 15 denotes a clutch claw formed to face the feeding rolls 12 and 13, 16 denotes a claw clutch A fixed to the outer periphery of the roll shaft 10, 17 denotes a clutch claw provided on a side surface of the feeding roll 14, and 18 rotates together with the roll shaft 10. And a clutch B rotatably supported by the side cover 8 in a state where the clutch B is slidably mounted in the axial direction at one end thereof.
7 has a clutch claw 18a opposed thereto. 19 is a fork guide for sliding the clutch B18,
Reference numeral 20 denotes a partition plate loosely fitted between the feeding rolls 12, 13, and 14 and has a ring shape.

[0012] Next, the operation will be described. In the state shown in FIG. 3, both the claw clutch A16 and the clutch B18 are disengaged, so that even if the roll shaft 10 is rotated by a motor (not shown), the feeding rolls 12, 13, and 14 do not rotate.

[0013] Now, the particulate was placed on the left side of the tank chamber 4B in FIG. 3, in a state containing the manure to the right of the tank chamber 4A, feeding the clutch pawls 18a slide in the right direction by the fork guide 19 and the clutch B18 When the roll 14 engages with the clutch pawl 17 of the roll 14, only the feed roll 14 rotates together with the rotation of the roll shaft 10 to disperse the particulate matter in the tank chamber 4B.
0 is slid to the right by the fork guide 11, the claw clutch A 16
5, the feed roll 12 also rotates together with the roll shaft 10, so that a large amount of fertilizer in the tank chamber 4A is sprayed. Conversely, when the roll shaft 10 is slid leftward by the fork guide 11, the claw clutch A16 The dispensing roll 13 meshes with the clutch claw 15, and the dispensing roll 13 rotates together with the roll shaft 10 to spray a small amount of fertilizer.

The above-described claw clutch A16 and clutch B18
When the on and off is done simultaneously or individually, spraying of only particulate matter,
Only a large amount of fertilizer is applied, only a small amount of fertilizer is applied, and a mixture of granular material and a large or small amount of fertilizer can be freely applied. Furthermore, by changing what is put in the tank chambers 4A and 4B or a combination thereof, a combination with a pesticide (herbicide) can be freely selected.

As shown in the above embodiment, each of the pay-out rolls 12
When the partition plate 20 is loosely fitted between the feeding rolls 12 to 14, the feeding rolls 12 to 14 are partitioned, so that each feeding roll 1
Each of the feeding amounts of Nos. 2 to 14 becomes accurate, and the frictional resistance decreases due to the interposition of the partition plate 20 of a different material when the respective feeding rolls 12 to 14 rotate.
