Description

[Detailed Description of the Invention] The present invention relates to a grass turning machine (tetsuda) and a grass collector (rake). More specifically, the present invention relates to a small-sized reversing grass collector that contributes to labor savings for small-scale pasture farmers.
Furthermore, the present invention relates to a small and economical reversing grass collector that can be attached to and removed from a walk-behind tractor as an attachment.

In recent years, due to agricultural policy, there has been a gradual increase in the number of small-scale pasture farmers who are converting paddy fields into upland fields and sowing pasture. However, conventional grass turning machines, grass collectors, and their combined use machines are all designed for large farms, and are therefore technically and economically unsuitable for use by small-scale dairy farmers.

This invention was developed based on the above-mentioned background.
The purpose of the present invention is to solve the above-mentioned problems by constructing a dual-purpose grass collecting machine as an attachment to a small tractor so that it can be attached and detached, and to obtain a machine suitable for small-scale dairy farmers.

To explain the embodiment shown in the drawings, 1 is a walk-behind tractor, 2 is its frame, and 3 is a handle. Power is transmitted from the PTO of the engine 4 to the shaft 9 of the wheel 8 via the belt 5, pulley 6, and transmission 7.
The tractor may be of any of a variety of conventional types.

A working machine 8 is removably attached, which is used both for the turning work of turning over the grass that has been cut and spread in the field and promoting drying, and the grass collecting work of accumulating the grass and making a windrow. Reference numeral 9 denotes a mounting base for the working machine 8, which is box-shaped in the illustrated example and connects the hitch 10 to the hitch 11 of the tractor 1. 12 is a planar U-shaped bracket fixed to the base 9; 13 is a gear box supported on the bracket 12 for free vertical movement on a cylindrical shaft 14; 15 is a cylindrical shaft 1 that can be attached to and detached from the bracket 12.
4, a retaining metal fitting; 16, a horizontal shaft case fixed to the gear box 13; 17, a gear box connected to the front end of the horizontal shaft case 16 so as to be rotatable left and right; and 18, a vertical shaft integrated with the gear box 17. It is a case.

A short horizontal transmission system is selected from two transmission systems: a pulley 181, a belt 20, and a pulley 22 integrated with the pulley 6, a pulley 19 coaxial with the pulley 181, a pulley 23 on a short horizontal shaft 24, and a belt 21 between them. Via the shaft 24, the bevel gears 25 and 26 in the gear box 13, the horizontal shaft 27 in the case 16, and the bevel gear 2 in the gear box 17.
8 and 29 to drive the vertical shaft 30.

A radial arm 31 is provided at the bottom of the vertical axis 30 and is open on all sides.
and attach elastic wire tines 32 to each arm 31. The vertical shaft 30 passes through the tube shaft 30a of the arm 31 so as to be movable up and down, and the tines 32 are moved up and down by several adjustment holes 33 and the connecting pin 24. 35 is a stabilizing shoe (or stabilizing wheel) rotatably attached to the lower end of the vertical shaft 30. In FIG. 4, 32a is a coil portion for mounting the tines 32, 36 is a coil holding plate, and 37 is a connecting bolt.

In the above configuration, when the work machine 8 is used as a grass collector, it is preferably rotated at 180 revolutions per minute, and when used for reversing work, it is preferably rotated at around 300 revolutions per minute. Therefore, the two-system belt transmission system 20 and 21 in Fig. 1 are replaced with belt clutches, etc.
Use it properly in 8/39.

Reference numeral 40 in FIG. 1 is a windrow forming rake (curtain) used when making a windrow W, and it is detachably attached to the horizontal shaft case 16 by an arm 50 and a socket 42. 41 is a wheel deflector (plate) for forming a windrow and preventing grass from clinging to the wheel axle.
It is removably attached to the work equipment mounting base 9.

When collecting grass, attach the curtain 40, operate the nut 49 shown in FIG. The tines 32 are tilted slightly forward and upward about the cylinder shaft 14. When driven by the low-speed belt system 21, the spread grass is blown away and hits the curtain 40, forming a windrow W (air drying row) between the grass and the board 41.

When reversing and diffusing, remove the curtain 40, loosen the bolt 46 shown in FIG. When the vertical shaft 30, arm 31, and tines 32 below the gear box 17 are set at an upward left angle in the direction of movement several times larger than when collecting grass, and are driven by the high-speed belt system 20, the spread grass is reversed by the tines 32. In other words, it scatters while inverting and diffusing.

Since the present invention has the above-mentioned configuration, even small-scale farmers can use a small walk-behind tractor that they already have or can easily obtain, and can easily perform grass turning work by attaching and detaching the work implement 8 to the tractor. It has the feature that it can be used as a grass collector or a row grass collector. Further, since the working machine 8 and its mounting mechanism have a simple structure as described above, they can be produced at low cost. Therefore, it is beneficial for small scale dairy farmers.
