DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a feeding mechanism for a sprayer for spraying granular pesticides, granular fertilizers, seeds and the like.

[0002]

2. Description of the Related Art When spraying granular pesticides, fertilizers, seeds, and the like, the general spraying rate per 10 ares is as large as 1 to 5 kg for granular pesticides and 5 to 50 kg for granular fertilizers (in the case of paddy rice). For this reason, in the conventional roll-type feeding mechanism, it is necessary to change the rotation speed of the feeding roll in a wide range. For example, when spraying 1 kg of herbicide per 10 ares and 50 kg of fertilizer per 10 ares, assuming that the feeding rolls of the feeding mechanism are the same (volume of the feeding amount), if the provisional specific gravity is the same, the herbicide 1 Fertilizer 50 ratio (1: 5
In step 0), the number of revolutions of the feeding roll must be changed. In practice, it can be even higher. In the conventional roll type feeding mechanism, the feeding amount in this wide range (1 to 50 times) is dealt with by changing the rotation speed of the roll shaft of the feeding roll or replacing the feeding roll. There is also a feeding mechanism that changes the feeding amount by changing the groove width of the roll,
Such a method is not suitable for feeding out a small-sized particulate pesticide.

[0003]

In the conventional feeding mechanism of the spreader, the rotation speed of the roll shaft is changed to cope with the wide range of feeding amount described above. Above, the torque at low speed rotation is reduced,
There is also a problem that the feeding roll cannot be fully turned, and when used in a state where the number of rotations is low, feeding unevenness such as intermittent feeding is increased. In addition, the method of changing the feeding roll to cope with a wide range of feeding amount has a problem in that it takes time to change the roll.

[0004] The present invention has been made to solve such a problem, and when using a large amount of application (for example, fertilizer), use a large amount of supply roll, and when applying a small amount such as a herbicide, use the same. By using a feeding roll with a small feeding amount, for example, if the ratio of the feeding amount per rotation between a feeding roll with a large feeding amount for fertilizer and a feeding roll with a small feeding amount for herbicide is 50: 1, the fertilizer The same rotation speed of the pay-out roll is sufficient for both spraying and spraying of the herbicide.Therefore, it is not necessary to change the rotation speed of the pay-out roll in a wide range as in the conventional case. There is no need to reduce the number of rotations of the roll, and there is no intermittent spraying.
Rolls A7 and B8 are fed by two power sources.

Reference numeral 6 denotes a fork guide for sliding the roll shaft 5, and reference numerals 7, 8, and 9 denote three feed rolls A, B, and C which are rotatably juxtaposed on the roll shaft 5 and have different feed amounts. Has a large feed amount, the feed roll B8 has a shorter axial length than the feed roll A7 and has a smaller feed amount, and the feed roll C9 has a significantly different shape from the two feed rolls A7 and B8. Is traced. Reference numeral 10 denotes a clutch claw formed so as to face the feeding rolls A7 and B8, 11 denotes a claw clutch A fixed to the outer periphery of the roll shaft 5, 12 denotes a clutch claw provided on a side surface of the feeding roll C9, and 13 denotes an end of the roll shaft 5 . rotatably in part

Next, the operation will be described. In the state shown in FIG. 1, since both the claw clutch A11 and the clutch B13 are disengaged, the roll shaft 5 is rotated by the motor M1 and
Even if the latch B13 is rotated by another motor 16 , the respective feeding rolls A7, B8, C9 do not rotate.

[0009] Now, in the case of spraying the fertilizer, the tank 1 data
Put fertilizer tank chamber 1A, to engage the claw clutch <br/> Chi A11 in clutch pawl 10 of the feed roll A7 by sliding the roll axis 5 by the fork guide 6 in the right direction. Thus rotating the roll shaft 5 by the motor M1, rotates only feed roll A7 together with the roll shaft 5 via a pawl clutch A11, it causes unrolled along the fertilizer the feeding amount of the feed roll A7.

Next, when it is desired to further reduce the amount of spray per 10 ares, the claw clutch A11 may be slid leftward, contrary to the above, so that only the feeding roll B8 rotates with the roll shaft 5.

Further, when a small amount of herbicide is to be sprayed, such as a herbicide, the herbicide is put into the tank chamber 1B of the tank 1, the clutch B13 is slid rightward by the fork guide 14, and the clutch claw 13a is pulled out of the roll C9. With the clutch claws 12 of the above . Thus, the clutch B13 is separated.
Rotation by the motor 16, only the roll C9 is rotated through the clutch B13 feeding can trace spraying herbicides.

If the ratio of the feeding amount (volume) of the feeding rolls A7 and C9 is designed to be 1:50, the fertilizer is fed by the feeding roll A7 and the herbicide is fed by the feeding roll C9. 50kg per 10 ares if sprayed
1kg per 10 ares even when spraying fertilizer with a large amount of feed
When even during spraying feeding a small amount of the herbicide, roll shaft 5 and Kura
The switch B13 may be rotated at the same rotation speed. Also, the ratio of the number of rotations of the roll shaft 5 and the clutch B13.
, And the feeding rolls A7 and B8
The ratio of the feeding amount with the roll C9 is simple and the feeding roll
It can be changed without replacing A7, B8, and C9 .

In the above description, the three feeding rolls A7, B
8, and C9 are used one by one.
By combining both clutches A11 and B13, it is also possible to use two of the three feeding rolls A7, B8 and C9 in combination, so that the change of the feeding amount can be adjusted widely.

As shown in the above embodiment, each feeding roll A
If the partition plate 15 is loosely fitted between 7, B8, and C9, the pay-out rolls A7, B8, and C9 are partitioned.
The feeding amount of each of the feeding rolls A7, B8, and C9 becomes accurate, and the frictional resistance decreases due to the interposition of the partition plate 15 made of a different material when the feeding rolls A7, B8, and C9 rotate.

[0015]

As described above, according to the present invention, when a large amount is applied (for example, fertilizer), a large amount of the supply roll is used, and when a small amount is applied such as a herbicide, the supply amount is small. By using a feeding roll, for example, when the ratio of the feeding amount of a feeding roll having a large feeding amount for fertilizer and a feeding roll having a small feeding amount for a herbicide is 1:50, the herbicide can be dispersed even when the fertilizer is applied. When spraying, the same rotation speed of the feeding roll is sufficient, so there is no need to change the rotation speed of the feeding roll in a wide range as in the past. There is no need to reduce the number of revolutions, and intermittent spraying does not occur. Also two power
Rotation of feeding rolls A7, B8 and feeding roll C9 depending on the source
Do not change the feeding roll by changing the number of turns
The ratio of the feeding amount of the feeding roll can be changed. Therefore, there is an effect that high spraying performance can be obtained.
