Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in the shear of a moldboard plow.

In bar point type mold board plows, worn bar points are successively projected to ensure durable use, but in the standard type sear to which the present invention belongs, the sheer is particularly worn out and cannot be used for long periods of time. It is unsuitable, and has drawbacks in terms of overall strength including shear points due to plough suction and the like.

In view of the above points, the present invention provides a series of standing pieces at the shoulder of the shear to strengthen not only the strength of the shear as a whole, but also the strength of the tip of the shear, which is particularly prone to wear and damage, and is also susceptible to impact. To provide a sear that protects the sear and further has an upright piece on the cheek that also serves as a connecting and fixing part with other connecting parts.

Below, the drawings showing the embodiments of the present invention will be explained.
is a shear which is a component of a moldboard plow, and as is well known, the moldboard plow is formed with other components such as a moldboard 6, a thin 5, a land side 7, etc. with a bed 9, a back metal 10, or a place. .

This shear 1 has an upright piece 4 on its shoulder 2 that has a substantially triangular side surface that becomes wider in the vertical direction from the shear point 3 to the rear end, as shown in FIGS. 1 to 3.
Form into the same body as 1.

The shape of this upright piece 4 is not limited to the above-mentioned substantially triangular shape on the side, and the upper edge or lower edge may have other shapes such as a bow shape.

The above-mentioned upright piece 4 has an upper upstanding part 4a located at the front of the shin 5 or the mold board 6 which also serves as a shin, and protects the shin etc. which receives direct strong impact from stones and other obstacles, and also protects the shin etc. from hard soil. Cut it to reduce the impact load on the plow.

In addition, the lower upright piece 4b of the upright piece 4 is joined and fixed to the side surface of the tip end of the land side 7, thereby ensuring a robust installation of the sear and covering and protecting the weak side face of the land side 7 caused by horizontal suction. do.

Further, by forming the upright piece 4 upright from the shear point, the strength of the thin portion of the shear point is reinforced, and accidents such as damage to the shear point due to obstacles in the ground are prevented.

Moreover, this upright piece 4 has an upper upright portion 4c as shown in FIG.
It may also consist of chisel, and this also has the same effect on protecting and strengthening Shiair and Shin.

Reference numeral 8 denotes a connecting hole, which is formed in a part of the upper upstanding parts 4a and 4c, and this hole 8 includes, for example, a connecting part of the lower end of a mountain blade that is located at the front of the plow body and cuts the soil. In this case, the upper end of the threaded blade is fixed to a beam, frame, etc.

It should be noted that, as long as the above-mentioned upright piece 4 satisfies the requirement that its starting point be the shear point, it goes without saying that the length up to the rear end of the shoulder opening does not occupy the entire length in an absolute sense.

This is clear from the fact that some of the effects brought about by the upright plate cannot be achieved unless the upright plate occupies the entire length of the shoulder opening.

As described above, in the present invention, the sear has at least an upwardly protruding upright piece at the shoulder opening, which is shaped so that it becomes wider from the tip of the sear to the rear end, thereby reinforcing the strength of the thin part of the sear point and preventing damage to the sear point. prevents damage and enables longer durable use.

In addition, the upright piece is located at the front of the shin, etc. to protect the shin, etc., and it also has mounting holes for connecting other parts such as the mountain blade, so separate connecting parts can be formed when connecting these parts. It also has the advantage of being able to be provided at a low price, and is highly effective as a shear of this type.

Claims (1)

[Scope of Claims] 1 In a moldboard plow, the shear is a moldboard in which upright pieces are provided in succession on the upper/lower surface or upper surface of the shoulder mouth in a rearward direction starting from the shear point, thereby reinforcing the strength of the shear. plow sear. 2. In claim 1, the upright piece of the sear is formed in a substantially triangular shape on the side that gradually becomes wider from the sear point to the rear end. 3. The upright piece for a sear according to claim 1, wherein at least a part of the upright piece that projects upwardly is provided with a through hole so that other connecting parts of the plow can be directly fixed thereto.
