Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ridge forming device used for forming ridges in a field.

As a method of forming ridges used for growing crops such as onions,
In a 1+tj field where raising has already been carried out using a rotary tiller, a molded sheet metal that presses the side surface of the ridge is attached to the rear of the rotary tiller; there is a method in which the ridge is formed using a ridge-forming device. According to this method, it is possible to widen the groove width between the ridges, but there is a drawback that soil falls into the grooves during ridge formation, making post-work difficult.

The present invention provides a ridge-forming device that can collect soil spilled into the groove during the ridge-forming process and utilize it for ridge-forming, and this will be described below.

FIG. 1 is a side view of an example of the ridge forming device according to the present invention, and FIG. 2 is a partially omitted plan view. The rotary tiller 14 includes a rotary tiller 14 having a tiller shaft 3, and a molded plate 5 attached to the rear thereof. The upper and rear parts of the tilling shaft B are covered by a rotary cover 6 and a rear cover 7, and a gear case 8 containing a bevel gear device is attached to the upper surface of the rotary cover 6. A transmission pipe 2 and a reinforcing pipe 9' are protruded from both sides of the gear case 8, and a chain case 1 is provided at the outer end of the transmission pipe 9.
0 is attached. Further, a side plate 11 is fixed to the opposite end of the reinforcing pipe 9'. The tilling shaft 3 is supported by bearings provided on the chain case 10 and the side plate 11. Inside the transmission pipe 9, there is a bevel tooth gear device fffi in the gear case 8.
A transmission shaft 13 connected to the input shaft 12 via f is housed therein, and rotational power is transmitted from the transmission shaft 16 to the tilling shaft 5 via the upper sprocket wheel and chain in the chain case 10. A board 15.15 is provided on both sides of the gear case 8, and a tail wheel 16 is provided at the rear of the board 15.15.
A rear hitch 17 is attached to support the. A mast 19 is attached to the upper part of the gear case 8, and the mast 19 and the rear pitch 17 are connected by a jack 20.

A bracket 21 is fixed to the chain case 10. A rectangular tube portion 22 is provided at the rear end of the bracket 21, as shown in FIG.
3 is undervalued by 1. The support column 23 is fixed to a rib 25 provided on the outer surface of the molded plate, and is fixed to a fixing bolt 26 provided on the square tube portion 22 of the bracket 21 in item 111.
．． 26'fr: If loosened, the molding plate 5 can be adjusted up and down 41.

The molded plate 5 has a flat plate portion 5 D in which the square tube portion 22 is provided.
, and a bundling board 5b that is inclined with respect to the front-rear direction so as to be located inward (toward the center of the fuselage) toward the rear from the flat plate part 5a, and a holding plate SCL fixed to the rear of the bundling board 5b. ``Yuuki 7 yosei plate 5[) and presser plate 5C are held in a state of being inclined in the vertical direction f so that the upper portions are further located inward.

A frame 6 is attached to the bracket 21 to which a frame 30 that protrudes in the RIF direction of the fuselage is fixed with bolts.
0 is provided with a horizontal line 31 that protrudes from the outside,
On this horizontal bar 31, a bar 32 that protrudes backward is fixed with a bolt.A hook-shaped bending bar 63 is pivoted at the rear end of the crossbar 32 so as to be able to rotate up and down (P). A strut 36 of a shoring disk 35 is attached to an arm 34 fixed to the lower end of the bending rod 36 with a bolt. The shoring disk 65 has a bowl shape and is supported at an angle θ with respect to the direction of travel, but the size of this θ can be adjusted by loosening the strut fixing screw 67 and turning the strut 36. .

Note that the bending rod 33 is a hanging rod 68 provided on the lower surface of the horizontal rod 31.
It is tied together with a spring 39, and is biased so as to press the mulch disk 35 downward.

This ridge forming apparatus 1 configured as follows includes a top link 40 of a power agricultural machine at the tip of the mast 19, a lower link 41 at the tip of the base plate 15, and #1. It connects and is pulled in the direction of the arrow. At this time, gear case 8
Rotational power is transmitted from the 1'ro shaft of the power agricultural machine to the input shaft 12 of the power agricultural machine, and the tilling shaft 6 is rotated.By this traction, a ridge 46 having a cross-sectional shape as shown in FIG. 4 is formed.
Soil tends to spill from the adjacent elevation 45 into the groove 44 formed at this time, and this spilled soil 46 often deteriorates the function of the groove. However, when all of the ridge forming apparatuses 1 are used, during the subsequent ridge forming work in the adjacent area, the mulch disk 35, which is open at the outside of the row cultivating apparatus, is removed. , 5th
Figure (as shown in this figure) -, 4620 - Since it sinks into the front part of the tari cultivating device, this second part is spilled into the groove 44.
It is removed from the inside and used for ridge formation. In addition, when trying to form a wide 11 groove as shown in FIG. 6, the groove 44 formed by the first ridge forming operation is
and the groove 44' formed by the second ridge forming operation.
However, since this ridge forming device 1 is equipped with a soil bundling disk 35 located outside of the tilling section, such a remaining section 47 is pushed down to the front part of the tilling section. A perfect groove is formed.

The shifting disk 65 is supported by support members such as the bending rod 33 and the arm 34 that protrude backward from the front, and is pulled by the 1 kg supporting member, so that the shifting disk 65 can be rotated forward from the rear. In addition, the upper shifting disk 35 is mainly attached to the frame 60 which is fastened with bolts, and the mounting is done by the arm 62. 34 etc. member f
Since it is supported by this, it can be removed when not needed.

As explained in Section 1, the ridge forming device according to the present invention has the following features:
-C1 which is supported in front of the rotary tilling device in an open state toward +iiJ and acts to guide the upper part outside the molding plate 5 to the front part of the rotary tilling device 114. Grooves can now be formed better when forming ridges. If this upper disk 35 is removably supported by a support member having a fulcrum in front of it as shown in the illustrated example, a smooth operating condition can be obtained and it can be removed when not needed. Therefore, I think it is even more convenient.
