Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a threshing machine frame and can be used in threshing devices such as combines and harvesters.

Problems to be Solved by the Invention When the threshing device is equipped with a swinging sorting device that receives threshed grain and sorts it while swinging, the swinging sorting device is particularly susceptible to stagnation and clogging of straw waste, etc. ,
Cleaning is frequently required, and therefore, it is necessary to make it easy to assemble, disassemble, clean, etc. the swing sorting device section.

Means for Solving the Problem This invention provides a threshing room 2 equipped with a threshing net 1 on the lower surface.
A handling barrel 3 is rotatably mounted on four shafts, and a transfer device 5 for clamping and transferring the threshing culm is provided along one side of the threshing chamber 2, and an upper machine frame 7 having a suction dust remover 6 at the rear. , a lower machine frame 10 equipped with a swinging sorting device 8 for receiving threshed grain leaking from the threshing room 2 and sorting it by swinging, and a sorting air passage 9 for wind-selecting the material to be sorted by swinging. are provided vertically and separably, and the side portion of the swing sorting device 8 of the lower machine frame 10 has an opening 11 that can open the upper center wall, and the front and rear walls 12, 13 of this opening 11. The threshing machine frame is provided with front and rear support frames 14 and 15 capable of supporting the upper machine frame 7.

Functions and Effects of the Invention When the upper machine frame 7 is mounted on the lower machine frame 10, when grain culms are supplied to the starting end of the transfer device 5, the threshing chamber 2 is The threshed grains are threshed by the rotation of the handling cylinder 3, and the threshed grains leak downward from the threshing net 1, etc., and are sorted while being oscillatedly transferred on the lower oscillating sorting device 8. The grains are then air-selected in the sorting air passage 9, etc. During this oscillating sorting operation, the oscillating sorting device 8 section is clogged with straw waste, etc., and when cleaning the inside after threshing is completed. By opening the opening 11, it is possible to take out clogged straw waste and perform cleaning, and when assembling and disassembling the interior, the upper machine frame 7 and the lower machine frame 10 are separated. By superposition and separation, the threshing net 1 part and the swing sorting device 8 parts are disassembled, assembled, cleaned, etc. from these separator frames 7 and 10, and during threshing work, the front and rear supports 14, 15 to open the opening 11
It is possible to stabilize threshing by reinforcing the support strength of the front and rear walls 12 and 13 having the following structure.

Embodiment The upper machine frame 7 has support arms 16 and 17 that support the handling cylinder 3 and the shaft 4 at the upper part of a sheet metal frame having a rectangular planar shape.
A threshing chamber cover 18 is provided over the support arms 16 and 17 so as to be openable and closable. The suction dust remover 6 is equipped with a cross-flow fan located on the rear side of the support arm 17 of the upper machine frame 7.
A culm passage 19 is provided above and a culm cover 20 that can be opened and closed is provided, and a culm processing device 21 such as a cutter or knotter is installed at the rear end to receive and cut or bind the culm. It is set up. The transfer device 5 is composed of a chain 22 and a clamping rod 23. The chain 22 is rotatably stretched in the longitudinal direction on one side of the upper machine frame 7, and the clamping lever 23 is attached to the support arm along the upper side of the chain 22. 1
It is provided on a pincher mounting frame 24 which is supported across the tips of the grain culms 6 and 17, and is provided so that the stock base of the grain culm can be held and transferred between the two 22 and 23. Further, in the culm discharge passage 19, there is provided a culm discharge device that takes over and discharges the threshed grain culm discharged by the transfer device 5. A threshing net 1 stretched along the lower side of the threshing room 2 is detachably provided inside the upper machine frame 7.

The lower machine frame 10 is located between both side walls 25 and 26, and the swinging sorting device 8 is configured on the upper part by a transfer shelf 27, a sorting leakage shelf 28, a stroke rack 36, etc., and the left and right sides are It is brought close to the inner surfaces of the walls 25 and 26 and supported so as to swing back and forth. Opening 1
1 is a side wall 25 on the side where the transfer device 5 is located, and the upper end edge is long open in the front and back, so that it can be seen in correspondence with the side surface, top surface, etc. of the inner swing sorting device 8. . This opening 11
Front and rear support frames 14 and 15 along the vertical direction are fixedly attached to the front and rear support frames 12 and 13 of the side wall 25 on the side having the side wall 25, or are formed integrally with sheet metal, etc., and these front and rear support frames 1
A bracket 34 provided at the upper end of the upper machine frame 7 and a bracket 35 provided at the lower end of the upper machine frame 7 are tightened and fixed with bolts, nuts, or the like.

In addition, at the front end of the lower part of the lower machine frame 10, there is a pressure winch 28.
A first receiving gutter 29, a second receiving gutter 30, etc. are provided at the lower part of the rear side, and between these receiving gutter 29, 30 and the swinging sorting device 8 on the upper side, a suction dust extractor is installed to remove the rear end. 6
A sorting air passage 9 is provided which communicates with the straw exhaust port 31 and the like. Reference numeral 32 denotes an opening/closing plate for opening and closing the opening 11, which is removably provided on the outside of the side wall 25. A straw waste guide plate 33 is provided on the outside of this opening/closing plate 32 to allow straw debris to fall from above, and is connected to a transmission mechanism section provided below.
