Description

Fertilizer feeder for foldable tractor}

The present invention relates to a foldable fertilizer supply device for a tractor. More specifically, it relates to a foldable fertilizer supply device for a tractor. It is mounted on a tractor and supplies fertilizer evenly according to the spacing between ridges formed in a rice paddy or field, and tilts with a single power through a link combination. This relates to a foldable fertilizer supply device for a tractor whose angle can be freely adjusted.

Generally, when growing crops in rice fields and fields, fertilizers are supplied to protect crops from diseases and pests and to increase yield.

In order to conveniently supply fertilizer to such large areas of rice paddies and fields, an automatic supply device that is coupled to a tractor and supplies fertilizer at high pressure has been proposed.

As a prior art, a 'tractor-mounted pesticide sprayer' has been proposed.

The prior art relates to a sprayer that is mounted on a tractor and sprays pesticides. It can facilitate the assembly and unfolding of pesticide spray pipes before and after use, provides a cushioning effect for the arm when contacting an obstacle, and can be used between a tractor and a pesticide sprayer. This relates to a tractor-mounted pesticide sprayer that allows easy distance control.

This makes it easy to assemble and unfold the arm for pesticide spraying before and after pesticide supply, and even if the arm is long, it prevents damage through a buffering effect when it comes into contact with an external obstacle.

However, in the prior art, the left and right arms, which are hinged on both sides of the central arm, are folded and unfolded through their respective hydraulic cylinders, which increases the volume and load and requires settings for the left and right arms to operate equally. There is.

In the conventional technology, pesticides are supplied from nozzles arranged at regular intervals, but typical fields are raised at a certain distance for the movement of water and people, and pesticides are sprayed in unnecessary locations, increasing the number of pesticide consumers and polluting the soil. there is a problem.

At this time, in the prior art, pesticides stored in one pesticide tank are sprayed through a nozzle, so there is a problem in that various fertilizers, pesticides, chemical solutions, etc. required for crop cultivation are sprayed individually, increasing work time.

In addition, crops planted in rice fields and fields are planted at different intervals depending on the cultivated species, so positioning needs to be adjusted so that they can be supplied to the correct location.

And the supply unit 600 is installed in the main frame 100, the first auxiliary frame 200, and the second auxiliary frame 300, respectively, as described above.

In this configuration, the main frame 100 can be connected to a tractor and then moved along roads, rice fields, and fields to supply fertilizer to crops.

That is, when the first auxiliary frame 200 is rotated to the rear of the main frame 100 by the operating unit 400, the second auxiliary frame 300 connected to the link bar 500 becomes the first auxiliary frame 300. It rotates to the rear of the main frame 100 in accordance with the auxiliary frame 200 and is arranged in a “ㄷ” shape.

Through this, the first and second auxiliary frames 100 and 200 can be folded and easily moved and stored on roads and narrow spaces.

And, fertilizer can be supplied to crops being grown in a rice field or field while the first and second auxiliary frames 100 and 200 are spread out on both sides of the main frame 100 by the operation unit 400.

At this time, the supply unit 600 adjusts the position and spacing of the supply hopper 620 according to the position of the ridge and crops, and then evenly supplies the fertilizer stored in the storage container 610.

At this time, the first and second auxiliary frames 300 can be adjusted to adjust their positions according to the paddy field, the raised bed, and the crops by adjusting the rotation angle to prevent the supplied fertilizer from being supplied to unnecessary land.

In addition, it is possible to evenly supply chemicals and crops to crops by adjusting the rotation angles of the first and second auxiliary frames 100 and 200 and the position of the supply hopper 620.

In addition, as the supply unit 600 is disposed on the main frame 100, the first auxiliary frame 200, and the second auxiliary frame 300, different types of fertilizers are stored at each location. , Different fertilizers can be supplied at the same time according to the crops, improving the convenience of work.

In addition, the height of the supply hopper 620 is adjusted according to the unfolded or folded state of the first and second auxiliary frames 100 and 200 through the position adjustment member 700 to prevent damage during movement, When supplying, it is done so that it is adjacent to crops.

That is, when the first auxiliary frame 200 is folded to the rear of the main frame 100, one side of the connecting wire 730 moves along the first auxiliary frame 200 and is connected to the main frame 100. And the supply hopper 620 disposed on the second auxiliary frame 300 is raised.

In addition, the connecting wire 730 is formed like the first auxiliary frame 200 in accordance with the folding of the second auxiliary frame 300.

Through this, when the first and second auxiliary frames 100 and 200 rotate, the supply hopper 620 is raised to prevent collision with obstacles formed on the ground during movement, and when used in rice fields and fields, the supply hopper 620 is raised. can be lowered to supply fertilizer while adjacent to crops.

Accordingly, the main frame 100 can be easily moved by being coupled to a tractor, and the fertilizer stored in the supply unit 600 can be supplied to crops.

At this time, the rotation angle of the main frame 100, the first and second auxiliary frames 100, 200 and the position of the supply hopper 620 are adjusted to match the spacing of the ridges formed in the paddy field and the spacing of crops, etc. It can be adjusted to supply fertilizer evenly and prevent it from being supplied to unnecessary areas.

In addition, a plurality of the supply units 600 are formed so that fertilizer can be selectively stored in each supply unit 600 and then supplied simultaneously or individually, thereby improving work speed and convenience.

And when the main frame 100 is moved, the first and second auxiliary frames 100 and 200 can be folded to efficiently move through narrow roads and narrow spaces. Damage and collisions caused by various obstacles protruding from the ground can be prevented by adjusting the height of the supply hopper 620 in accordance with the rotation of 200).

As above, the rights of the present invention are not limited to the embodiments described above but are defined by the claims, and various modifications and modifications can be made by those skilled in the art within the scope of the rights set forth in the claims. It is self-evident that you can do this.
