JPS6016271Y2 - Fertilizer stirring and dropping device in fertilizer spreading vehicle - Google Patents

Description

[Detailed explanation of the invention] Fertilizer often contains foreign substances, and bone meal fertilizers have hard bones mixed in from the beginning, so these foreign substances are often mixed into the fertilizer. The opening of the fertilizer packet may become clogged, and it is very difficult to make the fertilizer drop down the opening of the fertilizer packet at a constant rate and spread it evenly from beginning to end.

On the other hand, the conventional fertilizer stirring and dropping device of this type was
Constructed as described in Publication No. 5-88626,
Since the fertilizer in the fertilizer packet is stirred by the V-shaped stirring blades, the fertilizer is swung out by the stirring blades, making it difficult for the fertilizer to descend.

Therefore, if the fertilizer contains a large amount of moisture, the fertilizer will be compressed by its own weight, forming bridges and creating cavities within the fertilizer packet.

In addition, since the horizontal member with protrusions of the stirring bar is not an elastic body,
If it hits a large foreign object, it will damage the stirring rod or fertilizer packet.

There are problems with these points.

Therefore, in order to solve the above-mentioned problem, this invention has a boss that is pivoted in the bottom of the fertilizer packet mounted on the frame of the fertilizer spreader and drives and rotates. The inner part thereof is formed into an upwardly outwardly inclined surface, and a stirring blade is provided with the above-mentioned inclined surface rising sequentially from the base to the tip, and an elastic rod-shaped foreign matter remover is installed at the lower part of the other side. The O-shape stirring blades pull the fertilizer located on the outside of the fertilizer packet inward while pushing up the fertilizer located on the inside to circulate the fertilizer inside the fertilizer packet. The fertilizer is well stirred and descends smoothly, while foreign substances mixed in the fertilizer are removed.
The foreign object remover bends in the counter-rotational direction due to its elasticity and absorbs the impact while pushing it away, allowing small foreign objects to fall through the drop opening on the bottom plate of the fertilizer packet and being released outside the fertilizer packet, while large foreign objects that do not fall are removed. The body continues to push the inside of the fertilizer packet through the bottom of the fertilizer packet, and the foreign matter may clog the fertilizer packet's drop opening and block it, or the foreign matter may become stuck between the bottom plate of the fertilizer packet and the stirring blade, causing the stirring blade to become blocked. This invention relates to a fertilizer stirring and dropping device in a fertilizer spreading vehicle that is capable of stably and evenly distributing fertilizer from beginning to end while preventing damage.

They are connected by a chain transmission mechanism 46.

41 indicates foreign matter mixed into the fertilizer. Next, its effect will be explained.

When fertilizer is put into the packet 7 and the prime mover 39 starts operating, power is transmitted from the driving shaft of the prime mover 39 to the axle 4 via the transmission mechanism 42, transmission 40, and transmission mechanism 46 to drive the wheels 3. The machine then runs on its own at an appropriate speed.

At the same time, power is transmitted from the power intake shaft 41 of the transmission 40 to the rotating shaft 26 via the transmission mechanism 43, intermediate shaft 33, and bevel gear mechanism 34, and integrally with the rotating shaft 26, the stirring blade 28,
The boss 27 with the foreign matter remover 30 and the scattering plate 32 rotate in the direction of the arrow in FIG.

At this time, while the stirring blade 28 pulls the fertilizer located in the outer part of the packet 7 inward, the fertilizer is located in the inner part of the packet 7 by being guided by the upward and outward inclined surface of the stirring blade 28. Push up the fertilizer and circulate the fertilizer in the packet 7,
Even if the fertilizer contains a large amount of moisture, the fertilizer will be compressed by its own weight and form a bridge, causing the packet 7
To constantly agitate and descend fertilizer without creating cavities inside.

Therefore, when spreading fertilizer on both sides, use the spreading switching plate 1.
1 to the state shown in FIG. 7, and when spraying a large amount of fertilizer, set the application amount adjustment plate 17 to the state shown in FIG. By arranging the holes 12.18 to face the front and rear drop ports 8 and 9 and leaving the drop ports 8.9 fully open, the fertilizer in the packet 7 will be uniformly and sequentially dropped into the drop ports while being stirred by the stirring blade 28. From 8, 9 through holes 12 and 18 to the spreading plate 32
At the same time as the fertilizer falls upward, the fertilizer falling from the front drop opening 8 is thrown to the left by the spreading plate 32, and the fertilizer falling from the rear drop opening 9 is thrown to the right, so that the fertilizer is spread to both sides.

At that time, operate the nuts 38 on both sides to open and close the opening/closing plates 3 on both sides.
5 can be adjusted up and down as appropriate to adjust the spread width of the fertilizer on both sides.

Next, when spreading the fertilizer only to the left, pull the stopper 21 against the elasticity of the spring 22 to remove it from the recess 13, and then operate the lever 16 to the left and press the spreading switch plate 7. If the stopper 21 is released while rotating the spray switch 11, when the recess 14 of the dispersion switching plate 11 faces the stopper 21 as shown in FIG. Once inserted, the dispersion switching plate 11 is locked in the state shown in FIG.

Since the rear drop port 9 is closed by the scattering switching plate 11, the fertilizer in the packet 7 falls only from the front drop port 8, is blown off to the left by the spread plate 32, and the fertilizer is sent to the left. It is scattered in the direction.

At this time, when the rat 38 is operated to lower the right opening/closing plate 35 as shown by the chain line in FIG.
On the other hand, by appropriately adjusting the left opening/closing plate 35 up and down, the spread width of the fertilizer to the left can be adjusted.

In addition, if you want to spread fertilizer only to the right, operate the stopper 21 in the same way as above and operate the lever 16 to the right in the opposite direction to rotate the spreading switching plate 11. As shown in the figure, when the recess 15 of the spreading switching plate 11 faces the stopper 21, the stopper 21 moves backward due to the elasticity of the spring 22 and enters the recess 15, and the spreading switching plate 11 is locked in the state shown in FIG. do.

Since the front drop port 8 is closed by the spreading switching plate 11, the fertilizer in the packet 7 falls only from the rear drop port 9, is blown off to the right by the spread plate 32, and the fertilizer is sent to the right. distributed to.

At this time, if the nut 38 is operated to lower the left opening/closing plate 35 as shown by the chain line in FIG.
°C is completely prevented, and on the other hand, by appropriately adjusting the opening/closing plate 35 on the right side up and down, the spreading width of the fertilizer to the right can be adjusted.

Therefore, in the case of spreading fertilizer on both sides, the left side, or the right side, lift the adjustment lever 24 appropriately and
The spray amount adjusting plate 17 is rotated clockwise in FIG. 10 against the elasticity of the spring 23 through the f-shaft 5, and the drop openings 8 and 9 are adjusted appropriately by the spray amount adjusting plate 17 as shown in FIG. When it is closed, the amount of fertilizer to be spread can be arbitrarily adjusted while maintaining the fertilizer spreading state to both sides, right side, or left side by switching the above-mentioned spreading switching plate 11.

Further lift the adjustment lever 24 to move the spray amount adjustment plate 17 to the first position.
When rotated to the state shown in Figure 2, the spray amount adjustment plate 1
7 completely closes the drop ports 8 and 9 and stops spreading the fertilizer.

On the other hand, if foreign matter 47 is mixed in the fertilizer, the foreign matter 47 will reach the bottom of the packet 7 as shown in FIG.
After the foreign object tu1 remover 30 hits the foreign object 41, the foreign object remover 30 is elastically bent in the counter-rotational direction as shown by the chain line in FIG. 2, thereby absorbing the foreign object 47. to be pushed away.

Therefore, due to the foreign matter 47 being pushed out, the foreign matter 47 smaller than 1 part is removed from the drop opening 8 or 9 by the scattering switching plate 11.
and fall through the holes 12 and 18 of the spray amount adjustment plate 17 and are released outside the Bakut 7, while the openings 1 of the drop openings 8 and 9
Foreign matter larger than 1 part 4 that does not fall from the drop port 8.9
7 continues to be pushed inside the bottom of the packet 7, and the foreign object 4
7 is prevented from clogging in the drop ports 8 and 9 or between the bottom plate of the packet 7 and the stirring blade 28.

It should be noted that even if the foreign matter remover 30 is attached to the horizontal hole 29 of the boss 27 so as to protrude in the opposite direction to that shown in FIG. 2, it will function in the same manner as described above.

In the present invention, the fertilizer stirring and dropping device in the fertilizer spreading vehicle is configured as described above, so that the fertilizer located on the outer side of the fertilizer packet is moved inward by the O-shaped stirring blade installed on the boss of the drive rotation shaft. The fertilizer located inside the fertilizer packet is pushed up by the upward and outward slopes of the stirring blades while pulling the fertilizer into the fertilizer packet. Even if the fertilizer contained in
The fertilizer is compressed by its own weight, forming a bridge, and without creating a cavity in the fertilizer inside the fertilizer packet, the fertilizer inside the fertilizer packet descends smoothly one by one until it reaches the drop opening at the bottom of the fertilizer packet, until it reaches the end. Can be reliably dispersed.

Furthermore, if foreign matter is mixed in the fertilizer, when the foreign matter reaches the bottom of the fertilizer packet, the foreign matter eliminating body hits the foreign matter, and the cantilevered, elastic rod-shaped foreign matter eliminating body acts as a resistance to the foreign matter. Accordingly, due to its elasticity, it can be smoothly and satisfactorily attached to the boss by using the base as a fulcrum and bending in a curved manner in the counter-rotational direction to absorb the impact and thereby push the foreign object.

Therefore, as a result of the pushing, foreign objects smaller than the opening of the drop opening quickly fall from the drop opening and are discharged outside the fertilizer packet.

On the other hand, foreign objects that are thicker than the opening of the drop port (thus, and do not fall from the drop port) continue to be pushed through the bottom of the fertilizer packet, and the foreign objects may clog the drop port and block the drop port. The machine can be kept safe and the fertilizer spreading work can be carried out without the agitation blades getting stuck between the bottom plate of the fertilizer packet and the agitation blades, stopping the rotation of the agitation blades, or damaging the agitation blades by impacting them with foreign objects. Not only can it continue smoothly, but it also prevents foreign matter from clogging the fertilizer packet drop opening.
The fertilizer in the fertilizer packet falls evenly from the drop opening,
It has the advantage that it can be dispersed stably, has a simple structure, and can be manufactured easily and inexpensively.

On the other hand, if the fertilizer packet is configured in a downward-sloping shape, when spreading fertilizer by running the machine between the furrows in tea plantations, etc., the bottom of the machine will not get in the way of running, and the practical benefit will be that the work can be done smoothly. be.
