Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an elevating device for erecting trichomes.

(Prior art)

Conventionally, the raising case of this kind of grain stalk raising device has a pair of upper and lower sides (a pair of front and rear, that is, the raising case is generally inclined such that the starting end is located near the front ground and the end is located rearward and upward. The upper case can be easily attached to and detached from the lower case by providing a disengagement tool corresponding to the overlapping direction, that is, the vertical direction (or front and rear direction). What is configured to be able to do so is known.

[Problems to be solved by the invention]

However, according to such a conventional structure, it is convenient to remove the upper case when the straw waste is clogged with weeds in the case and it is necessary to clean the upper case during the work. Since the herd body is provided close to the front end portion of the case, the herb body becomes an obstacle, and there is a problem that the upper case cannot be easily attached or detached unless it is removed.

The present invention is such that the upper case of the raising case can be easily attached and detached without removing such a weeding body.

[Means for solving the problem]

The technical means of the present invention is a raising chain with a raising claw 13
The raising case 8 that houses the interior 14 is composed of an upper case 11 and a lower case 12 that can be divided into upper and lower parts.
The first case 19 and the first case 19 are respectively detachable by sliding the upper case 11 and the lower case 12 by sliding. Reference numeral 20 is characterized in that another second disengagement guides 21 and 22 having guide directions of the case different from each other by approximately 90 degrees are provided.

〔The invention's effect〕

Therefore, according to the configuration of the present invention, the upper case can be disengaged from the lower case by a sliding operation in the longitudinal direction. It is possible with one touch without.

In addition, since the guide restricting directions of the case are performed through engagement and disengagement guides that are different from each other by approximately 90 degrees, displacement of the upper case in the left-right lateral width direction and opening to the lower case can be prevented, and the restrictive guide can be reliably performed. It is.

〔Example〕

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of the combine, in which a threshing unit 3 and a driver's seat 4 are provided at an upper part of a body 2 having a traveling crawler 1, and a mowing part 5 is provided at a lower front part thereof. At the tip of the cutting frame 6 of the cutting unit 5, a weeding body 7 is provided, and further behind the cutting body 8 is inclined so that the raising case 8 of the plurality of grain stems is located rearward and upward at the end side from the starting side near the ground. Has been established.

The raising case 8 has a lower part attached to the mowing frame 6 by a bracket 9, and an upper part raising the drive shaft case.
Installed on 10. In addition, this raising case 8
Upper case (front case) 11 and lower case (rear case) 12
And can be divided up and down by and
A guide roller 15, a driving sprocket 16, and a tension sprocket 17 for winding a raising chain 14 with raised claws 13 mounted at predetermined intervals are pivotally supported at the inner upper and lower positions.

A guide body 18 is provided inside the lower case 12 to guide the user in a state where the claw 13 is raised while being raised on the operation path side.

In the two cases 11 and 12, first engagement and disengagement guides 19 and 20 which are disengaged by sliding the upper case 11 with respect to the lower case 12 in the longitudinal direction are provided.
An engagement protrusion 19 having a retaining bulge 19a at the tip on the side,
The lower case 12 has a V
The engagement guides 20 having the mold guide grooves 20a are provided at predetermined intervals in the vertical direction.

In addition, in the right place in both cases 11 and 12, the guide restricting direction of the case is arranged so as to differ from the first engaging and disengaging guides 19 and 20 by approximately 90 degrees, and the upper case is disposed in the longitudinal direction with respect to the lower case. Although the second engagement / disengagement guides 21 and 22 which are engaged and disengaged by the slide are provided, in the embodiment, the engagement protrusion 22 having the retaining swelling portion 22a at the tip on the lower case 12 side and the engagement protrusion 22 on the upper case 11 side are provided. At a position corresponding to the engagement projection 22, the V-shaped guide groove 21a
Is provided.

When attaching and detaching the upper case 11 to the lower case 12, first,
When attaching the detached upper case 11 to the lower case 12, the engaging projection 19 of the upper case 11 is engaged with the start end of the V-shaped guide groove 20a of the engaging guide 20 of the lower case 12, and Case 11
When the start end of the V-shaped guide groove 21a of the engagement guide tool 21 on the side is engaged with the engagement projection 22 on the lower case 12, and the upper case 11 is slid upward along this inclined direction, the respective engagement projection 19
.22 are the corresponding V-shaped guide grooves of the engaging guides 20 and 21
20a ・ 21a fits deeply and is elastically engaged and held,
Thereby, the mounting state of the upper case to the lower case is ensured.

When removing the upper case 11, what is necessary is just to perform in the reverse order to the above, that is, when the upper case 11 is pressed down, the respective engagement states are released, and the upper case 11 can be easily removed from the lower case 12. .

(Another embodiment)

As shown in FIGS. 5 and 6, the upper part of the raising case 8 is formed in a substantially U-shape in the lower case 12 in particular.
By providing the reinforcing plate 23 which continuously and continuously holds the wall surfaces 12a, 12b, 12c by welding means or the like, the rigidity of the case 12 itself is increased, and the case 12 is provided to increase the soundproofing effect by the contact of the raising claws 13. By attaching the soundproof rubber 24 to the reinforcing plate 23 via a fastener 25 such as a bolt, the soundproof effect of the raised claw and the rubber holding force are improved.
