Abstract

PURPOSE:To prevent the clogging of fertilizer in a pipe to introduce a fertilizer to a deep layer, to surely deliver the fertilizer from the delivery port at the lower end of the fertilizer introducing pike and to prevent the clogging of soil in the delivery port. CONSTITUTION:A fertilizer introducing pipe 20 is fixed to a machine frame 1. A delivery port 22 for fertilizing a deep layer is opened at the lower side end of the fertilizer introducing pipe 20 directing backward relative to the moving direction of the apparatus. Fertilizer supplied from a fertilizer hopper 43 is transferred toward the delivery port 22 with a rotary screw 30 in the fertilizer introducing pipe 20. The fertilizer in the fertilizer introducing pipe 20 can be surely and continuously delivered by the rotation of the screw 30 and applied to the deep layer. The clogging of the delivery port with soil can be prevented by the forced delivery of the fertilizer from the delivery port, in combination with the use of the delivery port opened at a side of the introducing pipe directing backward relative to the moving direction.

2. Description of the Related Art Conventionally, this type of fertilization device has a rotary tiller rotatable in a machine frame, as described in, for example, Japanese Patent Application Laid-open No. 56-102709 and Japanese Patent Application Laid-open No. 1-296912. At the same time, a fertilization conduit is located at the rear of the tillage rotary and applies fertilizer to a predetermined depth position in the machine frame. A structure is known in which a fertilizer hopper is fixed to the upper part of the fertilizer hopper, and one end of the fertilizer hose is connected in communication with the fertilizer delivery section at the lower end of the fertilizer hopper, and the other end is connected in communication with the upper end of the fertilizer conduit. ing.

[Problems to be Solved by the Invention] In the configuration described in each of the above-mentioned publications, the fertilizer supplied from the fertilizer hose of the fertilizer hopper to the fertilization conduit falls from the upper part of the fertilization conduit to the outlet at the lower end by gravity. And, the fertilizer is applied into the tilled soil from this outlet, but at this time, if the fertilizer has some moisture, the fertilizer may not fall down naturally and become clogged in the fertilization pipe. Continuous delivery of fertilizer may not be reliable, and since the outlet of the fertilization pipe is opened at the lower end of the fertilization pipe, soft soil may adhere to the outlet and clog the outlet. However, there is a problem in that the fertilizer may not be dispensed from this outlet.

[0005] The present invention has been made in view of the above points, and is capable of ensuring that the fertilizer supplied to the fertilization pipe is directed toward the outlet without clogging the fertilization pipe, and
It is an object of the present invention to provide a deep fertilization device that can continuously deliver fertilizer and that can reliably apply fertilizer to deep layers from a feeding port without clogging the feeding port with soil.

[Configuration of the invention]

[0007]

[Means for Solving the Problems] The deep fertilization device of the present invention includes a machine frame, a tilling rotary rotatably provided on the machine frame, and a tilling rotary provided at the rear of the tilling rotary for applying fertilizer to the deep layer. and a fertilizer hopper provided in the machine frame to supply fertilizer to the fertilizer application device, and the fertilizer application device has an upper end fixed to the machine frame, a lower end located in a deep layer, and a fertilizer hopper that is installed in the machine frame and supplies fertilizer to the fertilizer application device. A fertilization conduit with a feed-out port opened on the rear side of the direction, a screw rotatably provided in the fertilization conduit and for guiding the fertilizer supplied from the fertilizer hopper to the feed-out port, and a drive for rotationally driving the screw. It is made up of a source and a source.

[0008]

[Operation] In the deep fertilization device of the present invention, the tilling rotary is rotated while the machine frame is advanced, so that the tilling rotary sequentially tills the tilled soil.

[0009] Furthermore, when the tilling rotary is driven to rotate and the drive source of the fertilization device is activated to rotate the screw, this screw is rotated in the direction to feed out the fertilizer, and this screw moves the fertilizer from the fertilizer hopper into the fertilization conduit. The fertilizer supplied to the is forced sequentially toward the outlet, and
As the fertilizer is continuously fed out, this fertilizer is applied from the feeding outlet to the deep layer near the tiller.

[0010] When applying fertilizer to this deep layer, since the feeding port is opened at the rear side in the direction of movement, soil enters the feeding port together with the forced feeding of fertilizer by the screw, and the feeding port becomes clogged with soil. Fertilizer is reliably fed out from this feeding port without having to do anything.

This fertilizer is sequentially supplied into each connecting conduit 24 from the inlet 27 of each connecting conduit 24 via each fertilizer hose 48 .

Further, the rotation of the rotating shaft 38 of the electric motor 37 rotates the pulley 32 at one end, and the output from this pulley 32 causes each pulley 32 at the other end to rotate.
are sequentially rotated via respective belts 33 which are interlocked and connected, and the rotating shaft 29 of each pulley 32 is rotated, and each screw 30 feeds the fertilizer to the outlet 2.
It is rotated in the direction of feeding out toward 2. By the rotation of each screw 30, the fertilizer sequentially supplied into each connecting conduit 24 is forcibly delivered sequentially from each connecting conduit 24 into each respective fertilizing conduit 20, and each fertilizer application The fertilizer is forcibly delivered sequentially toward the delivery ports 22 of the conduit 20, and the fertilizer is sequentially and reliably applied to the deep layer near the tiller from each delivery port 22.

In this case, each fertilization conduit 20 travels through soil that has been previously tilled by the tilling rotary 5 and is swollen and softened, so there is no large resistance unlike when it travels through uncultivated soil. In addition, since the feedout port 22 is opened at the rear side in the direction of movement of the lower end of each fertilization conduit 20, each screw 3
Coupled with the fact that the fertilizer is forcibly delivered toward the delivery ports 22 at 0, the fertilizer is reliably delivered from the delivery ports 22 without soil entering into each delivery port 22 and clogging the soil. Ru.

Next, in the embodiment described above, in the fertilizing device 17, an inlet 27 is formed on one side of the connecting conduit 24, and fertilizer is supplied into the connecting conduit 24 from the inlet 27 on one side. Although the case has been described, the case is not limited to this, for example, as shown in FIG. Fertilizer may be supplied to In this case, the fertilizer hopper 43

Effects of the Invention According to the present invention, a screw is rotatably provided in a fertilization conduit having a feeding port at its lower end for directing fertilizer supplied from a fertilizer hopper toward the feeding port, and this screw is driven by a drive source. By rotationally driving the fertilizer, the fertilizer supplied to the fertilizing conduit can be reliably and continuously delivered toward the outlet without clogging the fertilizing conduit. In addition, since the feeding port is opened at the rear side of the lower end of the fertilizer conduit in the direction of travel, this combined with the forced introduction of fertilizer by the screw prevents the feeding port from becoming clogged with soil and ensures that the fertilizer can reach deep layers from the feeding port. can be fertilized. Furthermore, by storing different types of fertilizers in the fertilizer hopper, these different types of fertilizers can be reliably mixed while being drawn out toward the feeding outlet with a screw in the fertilizing conduit, and then fed out from the feeding outlet to the deep layer. . Therefore, it is possible to provide a deep fertilization device with a simple configuration and excellent workability.
