Description

[Detailed Description of the Invention] This invention relates to a fertilizer laying device for laying slurry-like manure of livestock or the like as fertilizer at a certain depth underground.

The purpose of this invention is to excavate a trench to a certain depth underground using a plow pulled by a self-propelled tractor, and also to pour slurry fertilizer from a fertilizer installation pipe installed at the rear of the plow. The present invention aims to improve the efficiency of fertilizer laying work by providing a fertilizer laying device that discharges fertilizer and lays it at a certain depth underground.

This invention will be described in detail below with reference to an illustrated embodiment.

In the figure, reference numeral 1 denotes a self-propelled tractor equipped with a crawler belt 3 around the suspension 2, and a laying device main body 5 is connected to the rear of the vehicle body 1a via a three-point pitch mechanism 4.

The cable laying device main body 5 has a structure in which a plow 7 is protruded from the bottom of a base 6, and this plow 7 can excavate a trench A in the ground, and the depth of the trench A is equal to the depth of the base 6. The height can be set arbitrarily by adjusting the height of a gauge wheel 8 mounted on the front part.

The inside of the plow 7 is formed into a middle chamber, and a sharp blade 7a is vertically protruded from the front edge to cut the soil well, and the lower end of the blade 7a extends from the lower tip of the plow 7. It is continuous with the chisel 7b that projects diagonally forward.

Further, at the bottom of the plow 7, a wing section 7C having a substantially triangular planar shape is provided to protrude horizontally, and this wing section 7C forms a horizontal groove a continuous with the groove A to a certain depth underground. The plow 7 can be excavated at any time, and a fertilizer laying pipe 9 is installed at the rear of the plow 7.

The lower end of the fertilizer installation pipe 9 is opened at the wing portion 7C, and the upper end is bent into a crank shape, and is connected via a hose 11 to a slurry pump 10 installed on the base 6. .

As shown in FIG. 3, the slurry pump 10 has a power shaft 12 rotated by a power take-off device (not shown) on the tractor side.
The suction side of the slurry pump 10 is connected to a fertilizer tank 14 mounted on the front part of the vehicle body 1a of the tractor 1 through a conduit 13 such as a hose. There is.

On the other hand, 15 is a hopper installed on the base 6, which stores fertilizer when laying granular fertilizer, and stores backfilling material when laying buried pipes such as drainage pipes (not shown). It is now possible to do so.

The hopper 15 has a discharge port 15a above the plow 7, and a pressure feeder 16 installed near the discharge port 15a.
This allows the fertilizer, backfilling material, etc. stored in the hopper 15 to be laid through the plow 7 into the trench A excavated by the plow 7.

Further, a screw 19 is provided at the bottom of the hopper 15 and interlocks with the power shaft 12 via a speed reducer 17 and a power transmission system 18 such as a belt. These smoothly discharge port 15
A hose reel 21 is installed on the front side of the hopper 15 for winding a buried pipe (not shown).

The buried pipe wound around the hose reel 21 is sent out into the groove A through the plow 7 by a delivery roll 22.

When laying the fertilizer, first, the plowing depth is set using the gauge wheel 8 so that the tip of the plow 7 reaches the depth to which the fertilizer should be laid, and in this state, the tractor 1 is advanced while rotating the slurry pump 10.

As a result, the plow 7 excavates a vertical groove A as shown in FIG. is laid in the horizontal trench a, and permeates into the ground through the crack b left by soil removal during trench excavation.

As detailed above, this idea involves excavating a trench to a certain depth in the ground using a plow pulled by a tractor with tracked suspension, and injecting slurry-like fertilizer into the trench. Since fertilizer such as livestock manure is placed at a certain depth, the fertilizer is not exposed on the ground surface, making it sanitary and improving the soil above the core.

In addition, since the fertilizer is laid at the same time as the trench is excavated, the fertilizer laying work can be carried out efficiently, and the tracked suspension of the tractor provides a large traction force, so the plow can easily move the top of the core. Can be powerfully excavated.

Furthermore, it is highly versatile as it is possible to lay liquid fertilizer and granular fertilizer, and the fertilizer tank installed at the front of the vehicle body acts as a balance weight to maintain stability during excavation, so the vehicle body does not shake unstablely when excavating. Fertilizer can be placed efficiently without moving.
