Description

[Detailed Description of the Invention] The present invention is mainly used for agricultural tractors, and relates to an attachment device for agricultural implements such as soil plates and valley raisers that are towed behind the tractor.

For example, in an agricultural tractor, as shown in Figure 1, a tiller called a rotary is pulled behind the main body A of the tractor, and a soil plate C is pulled behind it to streamline the work of making ridges in the field. I'm planning.

The soil plate C is attached to a support rod connected to the soil leveling machine B or the tractor body.

The conventional method for attaching agricultural implements such as soil cultivation boards is, for example, by omitting the pipe-shaped support rods in the middle, creating a pair on the left and right, inserting a separate thin mounting pipe into them, and attaching the soil to the mounting pipes at the middle part. A board is attached and flipped upwards when not in use to prevent it from touching the ground.

However, the conventional devices had the disadvantage that important attachment parts were inferior in strength and attachment of agricultural implements such as soil plates was troublesome.

In view of these points, the present invention has devised a mounting device that has a sturdy mounting portion and is easy to install and reverse when not in use.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a mounting device for a soil plate, etc. in a tractor of the present invention will be described based on the attached drawings.

A mounting seat 2 having a U-shaped cross section, a square tube, or a flat plate is welded to a predetermined position (usually the center position) of a support rod 1 supported directly or indirectly on the tractor body A, and has parallel surfaces on at least two upper and lower sides. form.

Then, as can be seen from FIG. 4, a base 3 having a substantially U-shaped cross section, which has a pair of left and right support plates 4, 4 welded in parallel, is fitted onto this mounting seat 2, and is attached using bolts 5, etc. It is removably fixed to the seat 2.

An arc-shaped guide window 6 is bored in the support plate 4, and holes 7 and 8 are bored in two places outside the guide window 6, above and below. Note that the arc-shaped guide window 6 extends slightly downward from its upper end to form a stepped portion 6a. These guide windows 6 and holes 7, 8 are provided to face each of the two support plates.

A connecting plate 10 provided with a mounting rod 9 for attaching the soil plate C is inserted between the two support plates 4, 4.

As shown in FIG. 6, this connecting plate 10 has a substantially U-shape as a whole so that the base 3 can be fitted freely therein.
The upper part has a hole 1 through which the guide pin 11 should pass.
2, and a hole 1 at the bottom through which the lock pin 13 can pass.
4 are drilled in each.

To attach the soil plate C etc., a base 3 having a support plate 4 is fitted onto the mounting seat 2 of the support rod 1 and fixed with bolts 5. Then, the connecting plate 10 is fitted into the base 3. First, the guide windows 6, 6 of the support plate 4 and the hole 12 of the connecting plate 10 are aligned, and the guide pin 11 is penetrated. Insert it into 6a. At this time, the lower hole 8 provided in the support plate 4 is aligned with the hole 14 provided in the connecting plate 10, and the lock pin 13 is fitted therein.

Thus, the connecting plate 10 is firmly supported at two points, the guide pin 11 and the lock pin 13, to prevent it from moving inadvertently.

A soil plate C is fixed to a mounting rod 9 provided integrally with the connecting plate 10 with a lock bolt 15.

During a series of operations, for example, when the soil plate C is not used temporarily, the soil plate C is inverted upward.

To turn the soil plate C upward, first remove the lock pin 13, then slightly lift the entire connecting plate 10 to which the soil plate is attached, and allow the guide pin 11 to escape from the stepped portion 6a. and guide pin 11
along the guide window 6, the entire connecting plate 10 (with the soil plate still attached) is turned over as shown in FIG. 7 and lock pin 13 here
Insert.

In this way, the soil plate C can be fixed in an upwardly supported state (inverted state).

According to the present invention, the support rod 1 itself at the part to which the soil plate is attached is integral, and can be made stronger than conventional ones and free from the risk of wobbling.

The installation work can be done easily and reliably. In particular, when temporarily inverting installed soil plates, etc., the work is extremely easy because the soil plates, etc. are connected to the support plate, base, and support rods and do not separate during the reversal operation. Also, there is no risk of parts being destroyed.
