Description

[Detailed description of the invention] In this invention, a pair of plows 1, 1 are connected by a telescopically adjustable connecting rod 2, and support rods 3, 3 of the same plow 1, 1 are respectively projected upward into the plows 1, 1. The support rods 3, 3 are each provided with a mounting bracket 4, and the metal fittings 4, 4 are attached to both tail wheel upright support rods 6, 6 of the tiller 5, respectively.
This invention relates to a furrow plow that can be detachably attached to a furrow plow. A pair of plows 1, 1 are arranged symmetrically inside the tail wheels 9, 9 on both sides as shown in Fig. 5, and are supported by support rods 3, 3 with a large space between the front parts in the forward direction. Support with 2 consecutive rods at small intervals. The connecting rod 2 connects adjustment rods 11, 11 from both ends of the pipe 10.
The rods 11, 11 and the pipe 10 are fixed with set screws 12, and both ends of the rods 11, 11 are fixed to the rear of the plows 1, 1. A mounting plate 13 is provided at the bottom of the support rod 3, and the plate 13 is attached to a bolt 14,
Attach it to the front of plow 1 with 15,15. The plow 1 can be adjusted up and down along the arcuate long holes 16, 16 to the solid line position or the imaginary line position in FIG. 2 using the rear bolt 14 as the center. The mounting bracket 4 has a short pipe 17 that is slidably fitted to the upper part of the support rod 3, and by fixing this to the support rod 3 with a set screw 18, the height of the mounting bracket 4 from the gap 1 can be adjusted. Can be adjusted. The short pipe 17 is provided with a plate 20 that is parallel to the short pipe 17 via a bracket 19, and bifurcated metal fittings 21, 21 with V-shaped openings are provided at the upper and lower ends of the parallel plate 20, and the metal fittings 21, 21 are parallel to the metal fittings 21, 21. By clamping the upright support rod 6 of the tail wheel 9 between the U-bolt 22 provided on the plate 20 and tightening the U-bolt 22, both the support rods 3, 6 can be fixed and the plows 1, 1 can be attached to the tail wheel upright support rods 6, 6. The tail wheel upright support rods 6, 6 are connected to the hitch 8 of the tractor 7 of the tilling machine 5.
It fits into mounting pipes 24 provided on both sides of the rear part of the machine frame 23 so as to be adjustable up and down, and is fixed with set screws 25. In addition, what is shown by 26 in the figure is a tilling rotary blade, 27 is a rolling wheel,
28 is a seeding hose, and 29 is a container for seeds, fertilizer, etc.

Therefore, when the tractor 7 is advanced, the tilling machine 5 is pulled and moved, and the rotary blade 26 can plow the ridge. As the working machine 5 moves, the pair of plows 1, 1 also move on both sides of the ridge in the advancing direction, thereby forming grooves (between ridges) on both sides of the ridge.

In conventional tilling machines, the plows are installed on both end faces of the cover of the rotary tillage blade 26, so the plows are installed only on one side of the tiller, and cannot be installed on both sides, resulting in poor support and poor support. It is difficult to form a groove on the other side of the ridge, which is inconvenient, and it is also difficult to apply it to other types of working machines.

Since the present invention is configured as described above, grooves (between furrows) are formed on both sides of the ridge as the work implement 5 advances by the pair of plows 1, 1, and the side grooves of the ridge of the first row or the last row are formed. Not only is it easy, but also a pair of plows 1,
1 is formed so that it can be detachably attached to both tail wheel upright support rods 6, 6 of the tilling machine 5 using the mounting bracket 4, so it can be used for different models of tilling machine 5. Regardless of the type of product, they are compatible and can be installed firmly and easily.
