It is.

(Prior Art) Conventionally, this type of pesticide is generally applied by mixing an appropriate pesticide with fertilizer and dropping the pesticide together with the fertilizer.

Therefore, devices for applying pesticides in this type of fertilizer applicator or fertilizer/seeder are not found.

(Problems that the invention aims to solve) Applying pesticides by mixing them with conventional fertilizers: (1) It takes a lot of effort and time to mix the pesticides.

(2) Once pesticides are mixed, it is difficult to freely adjust the amount of the pesticides mixed.

(3) It is difficult to mix pesticides uniformly.

There are problems with these points.

(Means for Solving the Problems) Therefore, in order to solve the above problems, this invention is based on a fertilizing and seeding machine in which a seeding machine B is attached on top of the fertilizer application machine a or on the back of the fertilizer application machine a.

Fits freely only when moving. Reference numeral 51 denotes a drop gutter provided below the delivery port 36 of the pesticide box 26, and the lower opening of the pesticide drop tube 1 connected to the lower end of the drop gutter 51 faces the rear of the groove cutter 16. 52 is a pesticide tank attached above the pesticide boxes 26 on both sides.

53 is a wheel installed on both sides of the rear part of the machine frame 4 by an axle 54, and the axle 54, the main shaft 11, and the main shaft 11
The rotary shaft 8 and the input shaft 17, the rotary shaft 8 and the rotary shaft 9, and the roll shaft 37 are connected by chain transmission mechanisms 55, 56, 57, 58, and 59, respectively.
60 is a saddle provided on the rear end of the machine frame 4.

Next, its effect will be explained. Put the machine into the field, put fertilizer into the tank 7, and take the seed box 14 from the tank 15.
When seeds are poured into the inside of the tank 52 and pesticides are put into the pesticide boxes 26 on both sides from the tank 52, and the tractor is started and the machine is moved forward, the wheels 5
3 rotates on the ground, and the main shaft 11, rotating shafts 8, 9, input shaft 17, and roll shaft 37 with a feeding roll 39 rotate from the axle 54 of the wheel 53 via the transmission mechanisms 55, 56, 57, 58, and 59.

Therefore, the fertilizer in the tank 7 is gradually stirred by the stirring piece of the rotary shaft 8 and splashed into the drop tube 2 by the protruding piece of the rotary shaft 9, and the fertilizer is transferred from the lower end of the drop tube 2 by the coulter 10. The fertilizer is applied by flowing into the fertilization groove, and then the subsequent double-sided disks 13 are placed on the fertilization groove.
Cover with soil.

On the other hand, the seeds in the seed box 14 are sequentially fed from the input shaft 17 into the drop tube 3 by a transmission-rotating seed transfer plate, and the seeds are transferred from the lower end of the drop tube 3 onto the covered soil made by the groove cutter 16. The water flows down into the seeding furrow and is sown.

In addition, the agricultural chemicals in the agricultural chemical box 26 are gradually removed from the roll shaft 37.
The pesticide is delivered from the delivery port 36 into the drop gutter 51 by the feed roll 39, and the pesticide passes from the drop gutter 51 into the drop tube 1 and from the lower end of the drop tube 1 to the groove cutter 1.
Immediately after 6, the soil is applied by falling into the seeding groove, and then the seeding groove is covered with subsequent soil covering metals 18 on both sides, and the top is compressed with rollers 19 to complete the work of fertilizing, sowing, and applying pesticides. .

At that time, if the nut 25 is loosened and the upper frame 23 is moved to one side along the guide bars 21, 21, the agricultural chemical boxes 26 and the agricultural chemical tank 52 on both sides will be moved together with the upper frame 23. , pesticide box 26
As the effective width of the feed roll 39 located inside becomes wider, the amount of pesticide fed out increases. On the other hand, upper frame 2
3 to the other side in the opposite direction to the above, the pesticide box 26
As the effective width of the feed roll 39 located inside becomes narrower, the amount of pesticide fed out decreases. Thereafter, by tightening the nut 25, the upper frame 23 is fixed at the position where the left and right movement is adjusted as appropriate.

In addition, after the work is completed, when the bolts and nuts 30 are removed and the lever 31 is unfixed, the bottom plate 27 rotates downward about the shaft 28 and the bottom of the agricultural chemical box 26 is opened, and the inside of the agricultural chemical box 26 is opened. of pesticides are removed by falling.

On the other hand, connect the lower opening of the agricultural chemical drop tube 1 to the seed drop tube 3.
By facing the rear of the fertilizer dropping tube 2 instead of the rear of the fertilizer drop tube 2, it is possible to apply pesticides after fertilization and then sow seeds.

In addition, in the fertilizer application machine, this pesticide feeding device c
If it is mounted on the fertilizer applicator and the lower opening of the pesticide dropping tube 1 of the pesticide feeding device c faces the rear of the fertilizer dropping tube 2, it will work in the same way as above to perform the work of fertilizing and applying pesticides. can.

(Effects of the invention) The device for applying agricultural chemicals in the fertilizer or fertilizer seeding machine of this invention has the following remarkable effects.

(1) Since a pesticide dispensing device is installed on the fertilizer applicator or fertilizer seeding machine and pesticides are applied separately from the fertilization or fertilization/sowing operation, (a) It takes a lot of time and effort to mix pesticides with conventional fertilizers. can be saved.

(b) It is possible to easily apply the necessary pesticides according to the type of fertilizer and seeds.

(c) Agricultural chemicals can be replaced freely.

(d) Fertilization or fertilization and sowing and application of pesticides can be done in an integrated process, resulting in good work efficiency.

(e) Pesticides can be applied evenly from beginning to end.

(2) A small amount of pesticide can be applied by adjusting the rotation speed of the pesticide feed roll.

(3) By adjusting the horizontal movement of the upper frame with the pesticide box, the effective width of the pesticide feed roll located inside the pesticide box can be changed, and the amount of pesticide applied can be freely adjusted in size, making it easy to operate. It is useful to work with.

(4) It has a simple structure, can be manufactured easily and inexpensively, and its operation is light and smooth.
