Description of the Related Art Conventionally, in this type of threshing apparatus, a technique for facilitating cleaning and maintenance of a handling room by swinging and opening a handling cylinder is disclosed in, for example, Japanese Utility Model Application Laid-Open No. 59-59. -15
It is publicly known from Japanese Patent No. 0231 and the like. [0003] In such a known technique, even if the handling cylinder is rocked and opened, maintenance cannot be easily performed with the rear straw conveying section being closed. However, there has been a problem that the maintenance of the entire threshing apparatus from the handling room to the straw conveying section cannot be sufficiently performed. [0004] In order to solve the above-mentioned problems, the present invention employs the following technical means. That is, the threshing apparatus is characterized in that the handling cylinder 2 and the straw transport chain 40 are configured to be swingably openable. As a result, when the handling cylinder 2 and the straw transport chain 40 are swung open, the part hidden by the handling cylinder 2 (for example, the upper part of the swing sorting shelf) and the straw transport chain 4
The opposing portion between the zero and the holding rod is opened, so that maintenance can be performed easily. As described above, the present invention provides a threshing apparatus characterized in that the handling cylinder 2 and the straw conveying chain 40 are configured to be able to swing and open. And the straw transport chain 40 are rocked open to open a part hidden in the handling cylinder 2 and an opposing portion of the straw transport chain 40 and the straw holding rod to facilitate maintenance of the threshing apparatus. be able to. In the illustrated example, a handling room 3 is framed by a front side plate 4, a rear side plate 5, a side frame 6, and the like. A handling cylinder 2 that rotates around the shaft 1 is installed, and a receiving net 7 is stretched along at least a lower half of the handling chamber, and is configured to be slidable and detachable. A feed chain 8 is stretched on one side of the handling room, and a grain culm is clamped and conveyed by a clamping rail 9 provided on the upper side. The feed chain 8 is constructed so as to be able to swing open and close together with a chain rail 10 around a vertical support shaft 11 provided at the start end thereof. 10A is a chain support frame, and 11A is a column protruding from the machine base, and a support stay protruding from the fixed side front side plate 4A of the handling room.
11B, the chain support frame 10A is rotatably mounted around the support shaft 11. Further, a handling drum cover 12 which covers the upper part of the handling chamber 3
A cover rail 9 of the feed chain 8 is attached to the cover 12, and the cover 12 is configured to be able to swing up and down in a vertical direction with a horizontal axis 13 in the front and rear direction as a fulcrum. The drive unit for the feed chain 8 includes a feed chain drive shaft 14a, 14b which is rotatably driven by a drive unit 14 and which is spline-fitted so as to be freely slidable, and a drive sprocket 15 for the feed chain 8. Are connected so as to be able to transmit power via a universal joint 16. When the feed chain 8 is opened with the front of the threshing unit as a swing fulcrum, it is necessary to arrange the swing fulcrum near the starting end of the feed chain in order to prevent interference with the harvesting transport chain and the inlet funnel. However, in this case, the feed chain drive unit and the swing fulcrum often shift, and gear meshing and power transmission by a pawl clutch have been proposed. Often occurs. Such a problem can be solved by transmitting power via the universal joint 16. The processing chamber 17 is provided with a feed chain 8 of the handling chamber 3.
A processing cylinder 18 which is arranged side by side on the side opposite to the side and receives the processed material sent out from the handling chamber 3 and processes it while transferring it rearward in the axial direction is internally mounted. The processing chamber 17 has a processing drum receiving network 19.
Is stretched so as to allow the grain subjected to the shedding process to leak to the lower sorting section. The processing cylinder receiving net 19 is configured so as to be able to be pulled out toward the handling room 3 side, and is usually locked and held by the side frame 6 of the handling room 3. The dust chamber 21 receives the processed material from the dust port 20 reaching the end of the processing chamber 17 and carries out dust processing while transporting the processed material rearward. ,
A dust-cylinder receiving net 23 is stretched at an appropriate position on the outer periphery. And
A dust outlet 24 is provided at the end of the dust chamber. The grain culm supplied into the handling room 3 is subjected to threshing by the handling cylinder 2. Processed materials such as straw chips and unprocessed particles generated in the handling chamber 3 are sent into the processing chamber 17 from the middle part, and are deagglomerated while being transported rearward by the processing cylinder 18, and are further discharged. It is sent into the room 21. Then, in the dust discharge chamber 21, the particles are removed while being transported backward by the dust discharge 22. The grains that have been shredding in the chambers 17 and 21 leak from the receiving nets 19 and 23 to the lower sorting chamber, and dust-treated materials such as straw chips are discharged from the dust outlet 24 to the outside of the machine. . The handling chamber 3 is configured such that the handling cylinder 2 and the receiving net 7 can be opened integrally and outwardly with respect to the lower sorting chamber and the processing chamber 17, that is, at the front end side of the handling chamber 3. In addition, the apparatus is configured so as to swing open and close in the horizontal direction on the vertical axis 26 provided on the machine-side frame 25 located on the processing chamber 17 side. By dividing the handling chamber in the vicinity of the communication port between the processing chamber 17 and the dust chamber 21, when the handling chamber is opened by swinging, the worker can put his body up to the dust body and can discharge the body. Removal, cleaning and inspection of the remaining paddy in the dust chamber becomes easy. The swinging fulcrum 11 of the feed chain 8
Is set in front of the swing opening / closing fulcrum 26 of the handling room 3, so that the opening angle of the handling room can be increased even if the opening angle of the feed chain is small, so that the processing chamber and the swing sorting shelf can be cleaned. Inspection is easy. The left and right side plates 27 and 28 behind the handling room 3 are connected and held by a casing 30 of a cross flow fan 29. In particular, the left side plate 27 is firmly held via a reinforcing frame 31 connected between the left side plate 27 and the fixed side rear side plate 5A of the handling room 3. Note that the swinging fulcrum of the handling chamber is related so that, when the swinging fulcrum is unlocked, the fulcrum is moved while the lower surface of the movable side front plate 4 is always in contact with the upper surface 4a of the fixed side front plate 4A.
