Description

TECHNICAL FIELD The present invention relates to a fertilizer spraying device which is particularly effective for use in a seedling planting machine.

(Prior Art) A fertilizer sprayer is provided with a rotor having a feeding groove at a lower portion of a hopper, and the feeding groove feeds a predetermined amount of fertilizer by the rotation of the rotor.

As the fertilizer, granular one is used. This granular fertilizer has high fluidity because it rolls and is effectively sprayed, but since it is made by solidifying the powder, it may also be crushed into the original powder during handling. .

This powder has poor fluidity and adheres to the inside of the pipe of the spraying machine, which becomes large and causes clogging, which hinders spraying. And since the seedling planting machine is used especially in a place where the water content is high, the trouble frequently occurs.

As means for removing this, there have been devised devices such as Japanese Utility Model Publication No. 62-70723 and Japanese Utility Model Publication No. 58-117811.

(Problems to be Solved by the Invention) By the way, in the device shown in FIG. 3 of Japanese Utility Model Laid-Open No. 62-70723, the net is above the rotor, and the rotor is crushed to remove the grains formed. In addition to that, the net requires a drive source.

Also, the invention of Japanese Utility Model Publication No. 58-117911 is a seeding machine, but since the seeds used are those coated with powder around, the seeds on the net are collected though it is a uniform one. Since it is a substance, the powder contained in the upper grain is also pumped up and sprayed, so the powder reaches the tube and a great effect cannot be expected.

(Means for Solving Problems) The present invention has the following configuration in order to solve these problems.

That is, the hopper 10 for storing fertilizer and the hopper
A cylindrical rotor 11 for feeding the fertilizer in 10 downward and a pipe 22 for guiding the fertilizer fed from the rotor 11 to the field are provided, and the rotor 11 is driven and rotated at a cylindrical axis position. The shaft 18 is provided, and the feeding groove 12 is formed on the outer circumference of the cylinder so that the groove width along the axial center direction can be adjusted.
In the fertilizer spraying device provided with, the shaft 18 for driving and rotating the rotor 11 is configured to be driven and rotated in a certain direction, and the fertilizer particles are passed to the dropping position of the fertilizer fed by the rotor 11 below the rotor 11. A net 20 is provided for passing finer powder than fine fertilizer granules.
Are provided in parallel with each other in the axial direction of the rotor 11 and in a state of inclining toward the pipe 22 in a direction intersecting with the axial direction of the rotor 11, and are separated from the fertilizer grains below the net 20. The fertilizer spraying device is characterized by having a powder receiving chamber 21 for receiving the powder.

(Operation) The fertilizer spraying device configured as described above has a hopper.
Granular fertilizer is put into the hopper 10, and the fertilizer in the hopper 10 is fed by the rotor 11 which is driven and rotated in a certain direction, and the fed fertilizer falls on the net 20. Here, the fertilizer grains flow toward the lower direction of the inclination of the net 20,
It is sprayed on the field through the pipe 22. On the other hand, powder finer than fertilizer grains passes through the mesh of the net 20 and is received by the powder receiving chamber 21. In addition, the amount of fertilizer fed out is determined by the feeding groove 12 of the rotor 11 ...
The feed amount is adjusted by adjusting the groove width along the axial direction. Even if the feed amount of fertilizer is adjusted in this way, the net 20
The fall position of the fertilizer on the top does not largely change with respect to the inclination direction of the net 20.

(Effects of the Invention) In the fertilizer spraying device of the present invention, all of the fertilizer fed out by the rotor 11 falls on the net 20, and the fertilizer powder is efficiently removed. In addition, the fertilizer that was fed out was net 20
The net 20 vibrates as it falls on top, and the mesh is less likely to be clogged with powder. Further, even if the feed amount of fertilizer is adjusted, the falling position of the fertilizer on the net 20 does not largely change with respect to the tilt direction of the net 20, so that the feed amount of fertilizer does not have to be lengthened in the tilt direction. The powder can be satisfactorily separated by the net 20 regardless of the adjustment of, and thus a compact fertilizer spraying device with a good powder separation can be configured.

(Example) Next, the Example of this invention shown in drawing is described.

A seedling planting device 4 is attached to the rear portion of the traveling vehicle body 3 supported by the front wheels 1 and the rear wheels 2 and moving forward by links 5, 5. The seedling planting device 4 is provided with a planting drive case 6, and is left and right by the power in the planting drive case 6 (forward and backward with respect to the paper surface of FIG. 1).
The upper part of the seedling mounting table 7 driven by is supported by a pillar 8 extending upward from the case 6 in a gate shape.

A U-shaped or R-shaped support frame 9 extends from the upper part of the column 8 toward the front, and a hopper 10 is fixed to the outer side or the inner side thereof.

A rotor 11 is horizontally supported at the bottom of the hopper 10,
The rotor 11 is provided with feeding grooves 12, 12 ... On its outer periphery, and the feeding amount of the fertilizer can be adjusted by adjusting the groove width of the feeding grooves 12, 12 ,.

On the side surface of the drive case 6, there is an arm 13 that is rotating or swinging, and a bell crank 14 provided at the upper part of the support column 8
It is connected to the rod with a rod 15, and this bell crank 14 is armed with a rod 16.
A ratchet wheel (not shown) is provided between the arm 17 and the shaft 18 of the rotor 11 so that the rotor 13 is forcibly rotated by the arm 13.

A discharge hopper 19 is detachably attached below the hopper 10. In this discharge hopper 19, a mesh 20 having meshes that do not allow fertilizer particles to pass is obliquely stretched, and below the mesh 20 is a powder receiving chamber 21.
At the lower end of the upper surface of the net 20, there is provided a pipe 22 for receiving the fertilizer flowing down on the net 20 and leading it to the field.
As shown in FIG. 2, the rotor 11 is provided so as to rotate clockwise, and the tip of the brush 23 extending from the inner wall of the hopper 10 comes into contact with the right side surface of the rotor 20. It is located under the contact. The powder receiving chamber 21 has a stopper on the bottom.
Although it is provided with 24 so that the powder can be discharged, the powder receiving chamber 21 may be detachable, and the net 20 may also be detachable.

 In the figure, 25 is a seedling planting rod and 26 is a float.

When this seedling planting machine is operated, the seedling planting device 25 takes out the seedlings on the seedling mounting table 7 and inserts them into the field while the seedling planting device 4 advances as the traveling vehicle body 3 advances, and the seedlings are transplanted.

At this time, the rotation of the arm 13 causes the rod 15 to rotate the bell crank 14
The rod 16, the arm 17, and the ratchet are transmitted to the shaft 18 after being converted into intermittent rotary motion, and the rotor 11 is rotated clockwise as shown in FIG. Then, the fertilizer that had entered the feeding grooves 12, 12 on the outer periphery was brush 23
While being scraped off what overflows in
After colliding with the net 20 and dropping the mixed powder through the mesh into the lower powder receiving chamber 21, only normal grains flow down on the upper surface of the net 20 and are guided to the field by the pipe 22, and the previous transplantation is performed. Sprayed beside the seedlings.
