Description

Powder fertilizer injector {THE INJECTING APPARATUS OF GRAIN TYPE FERTILIZER}

The present invention relates to a powder fertilizer injector that can effectively fertilize powdered fertilizers on crops, and more specifically, a rod-shaped fertilizer injector that can be pressed by holding both hands in a fertilizer barrel that can be carried on the back. In order to allow fertilizer in the fertilizer container to flow into the fertilizer injector by connecting it with a flexible fertilizer supply hose, press the bottom of the fertilizer injector at the fertilizer position to form a hole to allow fertilizer to be accommodated in the ground. The fertilizer injector releases the pressing force of the fertilizer in the state so that the fertilizer injector is automatically lifted by the spring's elasticity and the fertilizer is poured into the hole to fertilize. Simply press it against the ground, and a certain amount will be automatically fertilized. It is convenient and always quantitative fertilizer injection is possible to suppress the waste of fertilizer and not to inhibit the growth conditions of the plant. Also, when the fertilizer is carried, the fertilizer is completely sealed and the fertilizer accommodates and supplies one dose of fertilizer. The supply rod is detachably configured so that the amount of fertilizer can be easily changed and applied according to the type or timing of the plant, thereby maximizing the use effect and improving the reliability and safety of the product.

In general, when growing plants (crops), the reason for forming cultivation is to drain well, intensively supply nutrients to the plant, and to secure the air permeability of the soil.

Plants that grow and form ridges are plants that are vulnerable to moisture, such as pepper tobacco.

And, when growing the plant by forming a gyro, while growing around the plant to deodorize the nutrients supplied to the plant to suppress the growth of parasitic weeds, and cover the surface of the gyrus to prevent the pest from entering through the surface Cultivated by covering.

Plants that use a vinyl cover for this purpose include peppers, tobacco, etc., which form a ridge to cover the vinyl cover, and sesame seeds, watermelon melon, etc., grown on a flat ground.

On the other hand, when planting or seeding plants for planting, they are sowing or seeding after supplying enough fertilizer for plant growth to the soil.However, during the growth of plants, they supply a large amount of nutrients. Fertilizers should be provided in the middle of the harvest period, because only the maximum yield can be obtained.

In addition, fertilizers supplied at the harvest time should be directly supplied only to the root part so as not to get on the leaf part of the plant, and should be supplied in an appropriate amount so as not to supply excessive amounts.

However, in the case of growing a plant by covering the plastic cover after forming the mockup, in order to inject fertilizer, a small amount of fertilizer is injected through the planting hole, which is a part of the plant covered by the vinyl cover, and then the soil is covered with the hole again. The process is performed by the worker bowing down or squatting in the furrow, which is accompanied by pain in the human body, and the work is cumbersome and inferior in work, and also causes the hole of the vinyl to become large and the vinyl torn during operation. There is a problem that weeds thrive at the site and also because the fertilizer is injected into the hole of the toad into the eye of the worker, the amount of fertilizer injected is not constant, but when the excessive amount is injected, there is a problem that the growth of the crop is rather inhibited.

In order to solve the above problems, fertilizer injectors of various structures are known in the art, and among them, in Korean Utility Model Publication No. 85-1111, the injection actuator is a single cylinder and an inner cylinder which is moved up and down along the inner cylinder. It is composed of a large-scale fertilizer supply tank with a handle on the upper part of the inner cylinder, and the volume and weight of the injector body that the operator must carry and operate by hand is large and heavy. There was a lot of force and hassle in the lower part of the outer cylinder, and at the lower end of the inner cylinder, a separate loading chamber was installed so that a certain amount of fertilizer was dropped from the inner cylinder and injected into the ground. Again, the fertilizer loading amount (one batch of fertilizer) Depth of cut) was the overall structure is complicated and increased production projections are used to treat the problem of precise adjustment of gailcheung only cumbersome but also a difficult one meetings fertilizer dosage, etc. etc. are installed projecting the adjusting bolt to adjust acceleration ever.

In addition, fertilizer is discharged by opening the opening and closing hole which was closing the discharge part of the excavation part while excavating the ridge by forming the excavation part in the upper part of the cylindrical body for storing the fertilizer and the discharge part opening and closing the opening and closing hole in the lower part of the body. When excavation, the discharge port is arbitrarily opened during excavation, and the fertilizer is discharged before the injector gets stuck in the field tiller. There was a problem that was not properly obtained, resulting in the waste of fertilizer, which is uneconomical and unproductive.

In addition, since the fertilizer is not injected according to the opening and closing time of the opening and closing opening (구 路) opening time of the fertilizer is not easy to quantitative injection according to the crop has many problems.

The present invention is to solve and solve the problems of the existing device as described above, the object of the present invention is to avoid squatting in the furrows during fertilizer injection to facilitate the operation and at the same time simply press on the ground It can be automatically fertilized to allow a certain amount of fertilizer to be handled easily, and the fertilizer can be injected at all times to suppress fertilizer waste and not to inhibit the growth conditions of the plant. It is possible to improve the reliability and safety of the product, and it is also possible to easily change the application amount of fertilizer according to the type and time of the plant, by detaching the fertilizer supply rod that accommodates and supplies the fertilizer of one dose. To provide an injection device of powdered fertilizer that can be maximized,

In order to achieve the above object,

The present invention is to connect the rod-like fertilizer injector that can be gripped with both hands to the fertilizer barrel that can be carried on the back with a flexible fertilizer supply hose so that the fertilizer can be introduced into the fertilizer injector,

In order to renew the structure of the fertilizer injector, a cylindrical outer cylinder having a fertilizer inlet pipe is installed upwardly and detachably installed at an inner lower side of the outer cylinder, and a reinforcing pipe body having a fertilizer inlet coinciding with the fertilizer inlet pipe when assembling is presented. do.

In another aspect, the present invention is inserted into the reinforcement pipe so as to be able to lift and lower the rotation, so as to penetrate the fertilizer storage hole in the lower middle of the circular side transversely and to the top side to prevent the change of position of the fertilizer storage hole. A fertilizer supply rod having a flat portion for suppression is presented.

※ Unexplained code in the drawing ※

(H) shows holes formed in the ground,

(F) shows fertilizer.

In order to inject fertilizer into the crops, the present invention configured as described above uses the handle of the fertilizer injector 30 in a state of carrying a fertilizer container 10 containing powder-like fertilizer on the back using a suspender 10 '. When pressing the lower end of the fertilizer supply rod 34 protruding by the spring force of the spring (50) in the state holding the two hands to the fertilizer position of the ground (F) fertilizer (10) of the fertilizer (F) ) Is naturally down to the fertilizer supply hose 20 is filled up to the fertilizer inlet (32A) of the reinforcing pipe (32).

In addition, the inclined end portion 34E in contact with the ground is provided with a position to form a hole (H) while digging into the ground due to the pressing force, while at the same time the fertilizer supply rod 34 is reinforced by contracting the spring 50 due to the pressing force As the fertilizer receiving hole 34A is gradually raised by being immersed into the tube body 32, it is connected to the fertilizer inlet 32A of the reinforcing pipe 32 and filled to the fertilizer inlet 32A through the fertilizer supply hose 20. Fertilizer is introduced into the fertilizer storage hole 34A and stored.
