Description

[Detailed Description of the Invention] [Industrial field of use] The present invention relates to a hopper structure of a thresher equipped with a resin hopper for bagging grain.

[Conventional technology]

Conventionally, there are resin moldings to reduce the weight and cost of the grain bagging hopper of the thresher, but if the cover of the paddy opening of the hopper body is also made of resin, both are made of resin. Because it is manufactured, it tends to lack rigidity, and it is often deformed by the pressing force due to the manual closing operation of the cover, so even if the cover is pressed against the hopper body to close it, the distortion is large, A gap is likely to occur between the cover and the hopper body.

[Problems to be solved by the device]

Inside the hopper, paddy and dust are dancing as the paddy is being transported by the lifting device, and if the top opening of the hopper is closed with a cover, it will be sealed so that the paddy and dust will not leak to the outside of the hopper. However, in the conventional resin hopper, there is a tendency that the cover is apt to be incompletely sealed as described above.

An object of the present invention is to improve the degree of sealing between the cover and the hopper main body when the cover is closed, even though the hopper structure is a resin hopper by devising the hopper structure.

[Means for solving the problem]

In order to achieve the above-mentioned object, the present invention provides, in the hopper structure of the thresher described at the beginning, an opening for paddy, which is integrally formed with an upward rib on the periphery, is provided on the upper surface of the hopper body, and a downward rib is provided on the periphery. With the cover made of resin integrally formed, the rib of the cover is configured to be able to close the opening while surrounding the rib of the opening, and the both ribs of the cover and the hopper body in the closed state It is characterized in that a lock mechanism for tightening up and down is provided.

[Action]

According to the above configuration, rigidity is strengthened by rib formation both around the opening of the hopper body and around the cover. And, since both ribs of these both are tightened up and down in the vertical direction to close, each peripheral part of both is hard to be deformed, and the tightening force by the lock mechanism is evenly distributed over the entire abutment part between the cover and the hopper body. To act as
The tightness is improved.

Further, since the ribs of the cover and the ribs of the hopper body are laterally offset, the amount of protrusion of the cover from the upper surface of the hopper is smaller than that when the ribs are butted.

Further, when the cover is closed, the labyrinth action is caused by the overlapping of the ribs.

[Effect of device]

Therefore, it was possible to prevent the paddy and dust from leaking out from the opening as much as possible while making the hopper body and the cover both made of resin.

Further, there is an advantage that the amount of upward protrusion of the cover from the upper surface of the hopper can be suppressed to a low level, and the leakage preventing effect is further enhanced by the labyrinth action.

〔Example〕

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

As shown in FIG. 3, a mowing pretreatment unit (3) is provided at the front of a vehicle body (2) having a pair of right and left crawler traveling devices (1).
And a threshing device (4) to which grain culms are supplied from the pre-mowing treatment section (3), and this threshing device (4)
A grain bag bundling hopper (5) to which the grain from is supplied is arranged at the right rear part of the vehicle body (2), and a driver section (A) is arranged at the vehicle body (2) at the front position of this hopper (5). And a combine, which is an example of a thresher, is configured.

As shown in FIG. 3, the hopper (5) is a two-neck type that is composed of a hopper body (9), which is a resin molded product, and a cover (10). An upright pipe frame (7) and a rear side thereof are attached and mounted to a rear wall (8) of the vehicle body (2).

As shown in FIGS. 1 and 2, an opening (11) for paddy is formed on the upper surface of the hopper body (9) integrally with an upward rib (11A) around the periphery, and a downward rib (10A) around the periphery. The rib (10A) of the cover (10) is a rib (11A) of the opening (11) by the resin-made cover (10) integrally formed with
The opening (11) is configured to be able to be closed in the state of enclosing it, and the cover (10) and the hopper body (9) in the closed state are tightened from both upper and lower ends of the ribs (10A) and (11A). A lock mechanism (B) for raising is provided.

The cover (10) is swingably opened and closed about the horizontal axis by fixing a resin hinge portion (10a) integrally formed on the front side to the upper surface of the main body (9).

As shown in FIG. 1, the lock mechanism (B) is arranged at the rear end of the cover (10), and the tongue piece (12) and the cover (10) arranged on the inner surface side of the cover (10). A vertical axis (14) that vertically penetrates the cover (10) through the knob (13) on the outer surface side of the
The tongue piece (12) can be rotated by rotating the knob (13) with fingers.

That is, after closing the cover (10), turn the knob (13) to rotate the tongue (12) until it engages with the inner surface of the hopper body (15) of the rib (11A) of the opening (11). If you do
The cover (10) is pressed against the hopper body (9) in a closed state by the taper formed so as to go upward as it approaches the vertical axis portion (14) of the upper surface of the tongue piece (12). Since the tip end portion (12a) of the upper surface of the tongue piece (12) is spherically curved, engagement and disengagement with the inner surface portion (15) of the main body can be smoothly performed.

As shown in FIG. 1, the knob (13) in the open position has an inverted T-shape in a side view, and the knob (16) which is an upright portion forms the upper surface in a rear view as an upward convex arc. There is. Therefore, when the combine is stored, the hood to be covered with the fuselage is unlikely to be caught by the knob (16).

Set so that the tips of the ribs (10A) and (11A) are in close contact with the upper surface of the hopper body (9) and the inner surface of the cover (10) at the same time when the cover (10) is pressed and closed by the lock mechanism (B). By doing so, the degree of closure of the opening (11) can be made closer to that of perfection.

[Another embodiment]

The lock mechanism (B) may be configured as shown in FIGS.

That is, the knob (13) and the vertical axis portion (14) tongue piece (12) are provided on the hopper body (9) side, and the notch (17) with which the tongue piece (12) can be engaged is formed on the inner surface of the cover (10). Formed engagement part (1
8).

With this structure, the protrusion height of the knob (13) from the hopper body (9) can be made lower than that of the present embodiment.

Further, in this embodiment, the cover (10) is closed by the combination of the hinge (10a) and the lock mechanism (B), but only by the lock mechanism (B) provided at a plurality of positions of the cover (10). It may be closed.

It should be noted that reference numerals are added to the claims of the utility model for convenience of comparison with the drawings, but the present invention is not limited to the structure of the accompanying drawings by the entry.
