Abstract

PURPOSE:To provide the title unit so designed that both upper and lower cases are equipped with the first guide tools to make detachable through the sliding of the upper case against the lower case and the second guide tools differing in regulating the guided direction from the first guide tools, thereby ensuring the upper case to be simply detachable. CONSTITUTION:A raising case 8 within which a raising chain 14 having raising claws 13 is stored is made up with both detachable upper and lower cases 11, 12. To make up the upper case 11 so as to be detachable against the lower case 12, both the cases 11, 12 are respectively equipped with the first guide tools 19, 20 to make detachable through the sliding of the upper case 11 against the lower case 12 and the second guide tools 21, 22 differing in regulating the guided direction by ca. 90 degrees from the first guide tools 19, 20. As a result, the upper case of the raising case can be made simply detachable without the need for removing a grass dividing body as before.

Description

[Detailed description of the invention] [Industrial application field] TECHNICAL FIELD The present invention relates to a raising device for raising a erect culm.

[Prior art]

Conventionally, the lifting case of this type of culm lifting device has an upper and lower pair (front-back pair, that is, the lifting case is generally inclined so that the starting end is located near the front ground and the terminal end is located rearward and upward). ) cases are superimposed, and
It is known that both cases are provided with locking/detaching tools corresponding to the overlapping direction, that is, the vertical direction (or front/rear direction), so that the upper case can be easily attached to and detached from the lower case. .

[This is what the invention is trying to solve! Title]

However, according to such a conventional structure, when the upper case is clogged with straw, garbage, etc. during work and needs to be cleaned, the upper case can be easily removed, which is convenient; however, in general, Since the grass divider is provided close to the front side of the starting end of the raising case, this grass divider gets in the way, and there is a problem in that the upper case cannot be easily attached or detached unless it is removed.

The present invention enables the upper case of the raising case to be easily attached and detached without removing such a grass splitter.

[Means to solve the problem]

The technical means of the present invention is that a lifting case 8 in which a lifting chain 14 with a lifting claw 13 is housed is composed of an upper case 1 and a lower case 12 that can be divided into upper and lower parts. are configured to be detachable from the lower case 12, and both cases 11 and 12 have first engagement and disengagement guides 19 and 20 that engage and disengage the upper case 11 by sliding with respect to the lower case 12, and this first Second engagement and disengagement guides 21 and 22 are different from the engagement and disengagement guides 19 and 20 in the guide regulation direction of the case by approximately 90 degrees.
It is characterized by having the following.

〔Effect of the invention〕

Therefore, according to the configuration of the present invention, the upper case can be engaged with and detached from the lower case by a sliding operation in the longitudinal direction, so that it can be easily attached and detached without removing the grass divider as in the conventional case. It is possible to do it with one touch.

In addition, since the guide regulation direction of the case is performed through engagement and disengagement guide tools that are different from each other by approximately 90 degrees, it is possible to prevent the upper case from shifting in the left and right width direction and from opening with respect to the lower case, and to ensure regulation guidance. It is.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings. FIG. 1 is a perspective view of a combine harvester, in which a threshing section 3 and a driver's seat 4 are provided in the upper part of a machine body 2 equipped with running rollers 1, and a reaping section 5 is provided in the front lower part thereof. Reaping part 5
A grass division body 7 is provided at the tip of the reaping frame 6, and further behind it, a plurality of culm pulling cases 8 are installed diagonally so that the terminal end side is located further rearward and upward than the starting end side near the ground. There is.

The lower part of the lifting case 8 is attached to the reaping frame 6 by a bracket 9, and the upper part is attached to the lifting drive shaft case 1.
It is attached to 0. In addition, this raising case 8 is
Upper case (front case) 11 and lower case (rear case)
12, and is configured so that it can be divided into upper and lower parts, and there are lifting claws 13 at predetermined intervals in the upper and lower internal positions.
A guide roller 15 for winding the lifting chain 14 with attached drive sprocket 16. Tension block [-17 is supported.

Inside the lower case 12 side, a guide body 18 is provided that guides the lifting pawl 13 in an upright state on the lifting action path side.

Therefore, first engaging and disengaging guides 19 and 20 are provided in both the cases 11 and 12, which engage and disengage by sliding the upper case 11 with respect to the lower case 12 in the elongated direction. An engagement protrusion 19 having a retaining bulge 19a at its tip, and an engagement guide 20 having a V-shaped guide groove 20a at a position corresponding to the engagement protrusion 19 on the lower case 12 side are provided at predetermined positions in the vertical direction. They are placed at intervals.

In addition, the first engaging/disengaging guides 19, 20 are arranged at appropriate locations in the two-car cases 11, 12 so that the guiding regulation direction of the case is approximately 90 degrees different from the first engaging/disengaging guides 19, 20 in the longitudinal direction of the J upper case with respect to the lower case. Second engaging/disengaging guides 21 and 22 are provided which are engaged and disengaged by sliding, but in the embodiment, an engaging protrusion 22 having a protrusion 22a for retaining at the tip on the lower case 12 side is provided.
However, an engagement guide 21 having a V-shaped guide groove 21a is provided on the upper case 1 side at a position corresponding to the engagement protrusion 22. When attaching the removed upper case 11 to the lower case 12, engage the engagement protrusion 19 of the upper case 11 with the starting end of the V-structure guide groove 0a of the engagement guide 20 of the lower case 12,
Furthermore, the V-shaped beam inner groove 2 of the engagement guide 21 on the upper case II side
1. When the starting end a is engaged with the engagement protrusion 22 on the lower case 12 side and the upper case 11 is slid upward along this inclination direction, each of the engagement protrusions 19 and 22 engages with the corresponding engagement guide tool. V structure guide grooves 20a and 2 of 20 and 21
It is deeply inserted into 1a and is resiliently engaged and held, thereby ensuring that the upper case is attached to the lower case.

When removing the upper case 11, it is only necessary to do it in the reverse order to that described above, that is, when the upper case 11 is pushed down,
The respective engagement states are disengaged and the case can be easily removed from the lower case 12.

[Another example]

As shown in FIGS. 5 and 6, the upper part of the raising case ε is formed into a substantially U-shaped 3, especially in the lower case 12.
By providing a reinforcing plate 23 that integrally connects and holds the wooden surfaces 12a-12b-12c using a sweat attachment means, etc., the rigidity of the case 12 itself is evened out, and the soundproofing effect due to the contact of the raising claw 13 is improved. By attaching the soundproof rubber 24 provided on the auxiliary plate 23 to the auxiliary plate 23 via a fastener 25 such as a bolt, the soundproofing effect of the pulling claw and the bailing force of the rubber are increased.
