Description

Fertilizer Spreading Equipment {A Fertilizer Distributor}

The present invention relates to a fertilizer spreading device, and more particularly to a fertilizer spreading device for effectively spraying the processed compost or chemical fertilizers.

In general, in order to spread the compost or chemical fertilizers on the crops by hand or by using a machine to apply the fertilizer.

In the case of spreading the fertilizer by using a machine, when the compost piles up or hardens, the fertilizer mass is sprayed as it is, so that evenly spreading of the fertilizer on the crop is not achieved.

This adversely affects the proper growth of the crops, and the hassle of breaking up the fertilizer masses by hand and spraying them again.

In addition, the double grinder and the spreader can be avoided from this hassle, but in terms of cost is never beneficial.

The present invention has been made in view of this point, and an object of the present invention is to provide a fertilizer spreading device that can be simultaneously pulverized and spread in one device.

The present invention fertilizer spreading device for achieving the above object,

A gear box is provided to receive the rotational force of the motor and decelerate it to generate different first and second rotational forces. The first and second shafts transmit the first rotational force and the second rotational force generated from the gearbox, respectively. The first shaft is located inside the hopper and is provided with a grinding blade for grinding the fertilizer on the first shaft, and a feed screw for transporting the fertilizer to the lower side of the hopper, the second shaft is the hopper lower Located on the second axis is characterized in that the rotary blades for dispersing the ground fertilizer falling from the hopper.

The fertilizer spreading apparatus of the present invention configured as described above will be described with reference to the accompanying drawings.

1 is a cross-sectional view of the fertilizer spreading apparatus according to the present invention, the hopper 106 contains the fertilizer to be sprayed, the first shaft 103 is formed by protruding a predetermined height from the lower center of the hopper 106.

Grinding blades 108 and 109 and feed screw 107 are provided on the first shaft 103, and the upper grinding blade 108 is formed at an upper end of the first shaft 103 to form the first shaft 103. It acts to crush fertilizers with rotation.

The fertilizer pulverized by the upper grinding blade 108 is conveyed to the bottom of the hopper 106 by the conveying screw 107, wherein the fertilizer is conveyed while being pressed to the lower side by the conveying screw 107.

The fertilizer transported to the lower portion of the hopper 106 by the transfer screw 107 is pulverized once again by the lower blade 109 is dropped to the inside of the cover 112 through the fertilizer outlet 111.

The dropped fertilizer is discharged as if flying toward the opening 113 by the rotation of the rotary blade 105 provided on the second shaft (104).

That is, as shown in FIG. 2, the fertilizer dropped from the hopper 106 while flowing out of the hopper 106 is discharged to the outside through the opening part 150, thereby spreading the fertilizer having a directivity.

On the other hand, the fertilizer outlet 111 provided on the bottom of the hopper 106 is determined by the operation of the adjustment lever 110, the opening degree is determined, as shown in Figure 4 the bottom of the hopper 106 is the outlet When the adjustment lever 110 is turned to the left side is formed with two bottom layer is formed, the fertilizer outlet 111 of the bottom layer is matched to drop the fertilizer to the bottom, when turned to the right fertilizer outlet 111 of the bottom layer is closed fertilizer Does not fall.

Of course, since the opening degree of the fertilizer discharge port 111 can be determined according to the degree of turning of the adjustment lever 110, it can be adjusted according to the application amount.

On the other hand, the second shaft 104 is composed of a pupil axis of the hollow state, the first shaft 103 is formed as an internal shaft inserted into the pupil shaft.

That is, the second shaft 104 is wrapped around the lower outer side of the first shaft 103, the second shaft 104 is located inside the cover 112, the cover of the first shaft 103 ( It passes through 112 and extends to the inside of the hopper 106.

The rotation speed of the first shaft 103 and the second shaft 104 is different from each other, the rotation speed of the first shaft 103 is responsible for the grinding and transport of the fertilizer than the second shaft 104, Let it be slow

In addition, the rotation of the first shaft 103 and the second shaft 104 implements different rotation speeds by one motor 101, which will be described in more detail with reference to FIG. 3.

3 is a detailed cross-sectional view of the gearbox, where reference numerals 207 to 214 are bearings for smooth rotation of the rotary shafts 103, 104, 217, 218, and 216 is an oil seal.

First, the third shaft 217 inside the gear box 102 is rotated by applying a rotational force directly from the motor 101 to power the second gear 202 by the first gear 201 provided on the outside thereof. Will be delivered.

The second gear 202 rotates the rotary vane 105 by transmitting power to the second shaft 104 surrounding the first shaft 103.

At this time, the first gear 201 and the second gear 202 are reduction gears, the diameter of the second gear 202 is larger than the first gear 201 to reduce the rotational force of the motor 101 to the second shaft ( 104) to deliver.

Meanwhile, a third gear 203 having a smaller diameter than the second gear 202 is provided on the second shaft 104 to transmit the rotational force of the second shaft 104 to the fourth gear 204.

The fourth gear 204 is provided on the fourth shaft 218 to rotate the fourth shaft 218, and the fifth gear 205 rotates according to the rotation of the fourth shaft 218. .

The fifth gear 205 is provided on the fourth shaft 218 and is much smaller in diameter than the fourth shaft 218.

The rotational force of the fifth gear 205 causes the sixth gear 206 provided on the first shaft 103 to rotate. The sixth gear 206 has a relatively larger diameter than the other gears.

That is, the rotational force of the second shaft 104 is decelerated by the fourth gear 204, the fifth gear 205, and the sixth gear 206 and transmitted to the first shaft 103.

Therefore, the rotation speed of the second shaft 104 is smaller than the rotation speed of the motor 101, and the rotation speed of the first shaft 103 is smaller than the rotation speed of the first shaft 104.

In brief description of this, the rotational force transmission of the second shaft 104 is

Motor 101-Third Shaft 217-First Gear 201-Second Gear 202-Second Shaft 104

Made of

The rotational transmission force of the first shaft 103 is

Third Gear 203-Fourth Gear 204-Fourth Axis 218-Fifth Gear 205-Sixth Gear 206-First Axis 103

Is done.

As such, the rotation of the grinding blades 108 and 109 and the feed screw 107 is relatively slow, by generating the rotational force of the first shaft 103 and the second shaft 104 at different speeds using one power source. The rotation of 105 can be made relatively fast.

As described above, the fertilizer spreading apparatus according to the present invention, by using a single power source to perform the pulverization and spraying at the same time, there is a great effect on the ease of use and the cost of the machine.
