As a result, the communication port guide 50 is directly fixed to the rear partition plate 6b, so that the dust leakage leaking tool 8d is inserted into the rear side surface of the rear partition plate 6b. Projections such as nuts are eliminated, so that the rear partition plate 6b and the dust discharge leaking tool 8d can be reliably brought into close contact with each other, and the dust discharge leaking tool 8d can be easily assembled and removed. is there.
As shown in FIGS. 9 and 10, on the rear side of the rear partition plate 6b, on the upper side of the dust cylinder casing 48, one side of the dust cover 51 is inclined from the upper right side to the lower left side and has a vertical part. Is attached to the rear partition plate 6b with bolts and nuts, etc., and the other side is connected to the rear end of the inclined surface of the dust cover 51a after being fixed to the fan casing 38b of the dust fan 38. This is a configuration provided.
Conventionally, the dust exhaust cover 51 is not provided above the dust exhaust casing 48. However, according to the present invention, the dust exhaust cover 51 is provided above the dust exhaust casing 48. Accumulation of soot and the like on the dust cylinder casing 48 can be prevented. Further, at the time of discharge and transfer to the rear of the soot, the tip of the soot moves from below to above, but since the shape of the dust cover 51 coincides with the path through which the soot flows, the transfer of the waste is not hindered.
As shown in FIGS. 8 and 9, the rear portion of the rear dust cover 51a is cut at a height position substantially the same as the height of the upper surface of the fan casing 38b of the dust fan 38 to provide a notch 51b. At the same time, the shape of the notch 51b is a notch 51b formed by cutting to substantially the same gradient as that of the dust cover 52.
Thereby, the dust passage can be secured. Further, the configuration of the evacuation part can be simplified.
As shown in FIG. 10, the rear dust cover 51a is mounted on the fan casing 38b and integrated on the dust cylinder casing 48. Further, the dust cover 51 is configured to be detachably attached to the rear partition plate 6b with bolts and nuts.
Thus, the rear dust cover 51a and the fan casing 38b are integrally formed, so that no gap is generated in the joint portion of the fan casing 38b. Further, since the bolts, nuts, and the like do not protrude, it is possible to prevent the transporting rod from being caught.
A handling cylinder cover 53 is provided at the upper part forming the threshing chamber 7 so as to be freely opened and closed as shown in FIGS. 17 to 19, and the construction of the opening / closing fulcrum of the handling cylinder cover 53 is on the upper side of the right side plate 5b. An auger receiving device 44e for receiving the discharge auger 44 is provided on a receiving plate 54a provided on the upper side of the rear portion of the opening / closing support frame 54. The auger receiving device 44e is provided at the lower end portion of the auger column 44b. The lower support plate 44c is mounted and provided, and a V-shaped receiver 44d is fixed to the upper end portion of the auger column 44b.
Between the receiving plate 54a provided on the front side of the opening / closing support frame 54 and the mounting plate 55a provided on the processing cylinder gear case 55, a lower mounting plate 56b provided on the lower end portion of the rear column 56a, and an upper end This is a configuration in which a rear frame 56 including an upper mounting plate 56c provided in the portion is provided. The lower mounting plate 56b is mounted on the mounting plate 55a of the processing cylinder gear case 55 with bolts and nuts, and the upper mounting plate 56b is mounted on the receiving plate 54a of the open / close support frame 54 with bolts and nuts.
Thereby, the strength of the mounting portion of the auger receiving device 44e that receives the discharge auger 44 can be increased.
As shown in FIGS. 20 and 21, the front side plate 4a is fitted with a transmission gear case 57a with a transmission mechanism 57b in the upper part, and with a transmission mechanism 57d in the middle in the vertical direction. The transmission case 57c is pivotally supported by support members 57e and 57e provided on both the left and right sides, and the support members 57e and 57e are mounted on the front plate 4a. The transmission gear case 57a and the middle transmission case 57c are connected and reinforced by the connection plate 57f.
As shown in FIG. 20 and FIG. 21, left and right support metals 58a and 58b are provided at the lower portions of the left and right plates 5a and 5b where the sorting blower 33 and the like are located. The lower frame 58 is pivotally supported by support metals 58a and 58b, and the left and right plates 5a and 5b are supported and reinforced.
The right support member 57e and the lower frame 58 have a structure in which a support arm 59 is provided and connected as shown in FIGS.
The middle transmission case 57c and the left and right support devices 24c and 24c for supporting the support pipe rod 24b are individually connected by providing left and right connecting plates 60a and 60b as shown in FIGS. This is a reinforced configuration.
Thereby, the strength of the support of the transmission part of the threshing machine 2 could be greatly increased by providing the left and right connection plates 60a and 60b and the connection plate 57f which were not provided conventionally. A belt cover 61 that covers from above the belt 61c that is provided on the rear side of the rear partition plate 6b and that extends over the left and right dust draining pulleys 61a and 61b is a waste transporting device 62a as shown in FIGS. It is the structure provided in the exclusion support frame 62 which supports the. Further, the belt cover 61 is provided close to the handling cylinder cover 53. 61d is a tension pulley.
Thereby, it is possible to prevent the sawdust accumulated on the tension pulley 61d.
24 and 25, the input gear case assembly 63a, the input gear case assembly 63b, and the barrel assembly 63c are divided. These input gear case assemblies 63a and 63b are detachably provided on the front plate 4a, and the barrel assembly 63c is detachably provided between the front plate 4a and the rear partition plate 6b. is there.
The input gear case assembly 63a and the handling cylinder assembly 63c are divided into two parts, and the outer handling cylinder shaft (not shown) and the inner handling cylinder shaft 64 are divided into two parts so as to be detachable. is there. The outer handling cylinder shaft divided into two and the inner handling cylinder shaft 64b are simply connected by a spline or the like.
A hole 4c through which a handle flange key 65 can be driven is provided in the handle shaft insertion portion of the front side plate 4a to which the input gear case assembly 63a is mounted. This handle cylinder flange key 65 is configured to be inserted into each key groove portion of the handle cylinder flange 7d and the inner handle cylinder shaft 64b.
When removing the barrel assembly 63c, when the input gear case assembly 63a is removed from the front plate 4a, the barrel flange key 65 provided on the inner barrel shaft 64 of the barrel assembly 63c is moved to the front plate. It is the structure visible from the hole 4c of 4a. A handling rod assembly 65 is obtained by applying a nine-stick 66 to the handling cylinder flange key 65 visible from the hole 4c and hitting it with a phantom 66a, etc., removing the handling cylinder flange key 65 and extracting the inner handling cylinder shaft 64. Remove 63c.
Accordingly, the handling cylinder flange key 65 can be easily removed, and thus the handling cylinder assembly 63c can be easily removed.
