Description

[Detailed Description of the Invention] The present invention is to open the opposing rotating plates inward in the rotational radial direction between the circumferences of the opposing rotating plates fixed to the rotating shaft at appropriate intervals in the axial direction of the rotating shaft. The present invention relates to a handling barrel of a threshing device in which a plurality of handling tooth mounts having a cross-sectional shape or a shape similar thereto are bridged and fixed at appropriate intervals in the circumferential direction of rotation.

In the above-mentioned handling cylinder, a cross-sectional shape or a similar shape is used as the handling tooth mounting base in order to reduce the weight of the entire handling cylinder and maintain the necessary strength. Inside the stand,
When the dust accumulated during threshing and the handling cylinder restarted,
There was a drawback that if the accumulated dust rose up again and floated around inside the handling barrel, the condition would repeat.

In view of these circumstances, the present invention aims to solve the above-mentioned drawbacks by adding a simple structure, and to provide a device with excellent strength.

A characteristic feature of the handling barrel of the thresher according to the present invention, which has been made to achieve the above object, is that a dustproof cover is fixed to the open portion of each of the threshing tooth mounts to close the opening.

The effects of the present invention having such a characteristic configuration are as follows.

In other words, the dust-proof cover that closes the open part of the handle tooth mount, which is formed into a cross-sectional shape or a similar shape to have necessary and sufficient strength while reducing weight, is fixed to the open part. This reliably prevents dust from accumulating in the open part during threshing. Moreover, since the dustproof cover is fixed in a connected state between both side plates formed upright to form an open part of the handle tooth mount, it can be used as a reinforcing material for the handle tooth mount. In addition, the cover can be thin and light enough to perform the dustproof function, so it can be constructed with even greater strength without sacrificing the desired weight reduction. It came to this.

Embodiments of the configuration of the present invention will be described below with reference to the drawings.

As shown in Figure 1, there is a reel 1 that scrapes the planted grain culms toward the rear of the machine, a cutting blade 2 that reaps the raked grain culms, and a cutting blade 2 that receives the harvested grain culms and collects them toward the center in the width direction of the machine. A reaping section 5 is provided at the front of the machine body, and is equipped with an auger 3 that sends the harvested grain to the rear of the machine body, and a conveyor 4 that conveys the harvested grain culm to the rear of the machine body with the ears leading. A device 6 for threshing the harvested grain culm and a tank 7 for recovering the grain after threshing are installed at the rear of the machine, and a crawler traveling device 8 and an operation control section S are also installed to provide a whole culm input type threshing system. A combine has been configured.

The threshing device 6 includes a handling section 9, and a pair of beaters 10, 10 for discharging the processed material after threshing in the handling section 9 to a sorting section 11.
Further, the sorting section 11 is configured to transport the processed material discharged from the handling section 9 to the rear, sort out grains, branch straw with grains, etc., drop them downward, and discard them. A stroke rack 13 is provided for swinging and carrying out the straw to the dust outlet 12.

To explain the handling section 9 in detail, as shown in FIGS. 2 to 5, the handling barrel 9A has a rotating shaft 15 pivotally mounted between the lateral outer plates 14, 14, and the rotating shaft 15 includes: Between the circumferential parts of opposing rotary plates 16, 16 fixed at an appropriate interval in the axial direction,
A plurality of handling teeth 19 mounts 17 having a cross-sectional shape that opens inward in the rotational radial direction or a similar shape are bridged and fixed at appropriate intervals in the rotational circumferential direction.

As shown in FIGS. 4 and 5, the handling tooth 19
Both side plates 17 forming the open portion of the mounting base 17
A plurality of cover mounting plates 17b are fixed in the longitudinal direction between a and 17a, and female screws 17c are fixed. A dustproof cover 18 that closes the opening is fixed to the cover mounting plate 17b by tightening bolts 17d to the female threads 17c.

In the figure, 19 is a handling tooth, and 20 is a concave.
