The threshing apparatus shown in FIGS. 1 and 2 has the following configuration.
That is, the threshing apparatus 1 is provided with a handling cylinder 3 that drives and rotates the tip portion of the cereals that are conveyed while holding the stock by a threshing feed chain 4 that is stretched on one side of the handling chamber 2. It is configured to thresh. A receiving net 5 is stretched around the lower half of the handling chamber 2, and a handling cylinder cover 6 that covers the upper portion of the handling cylinder 3 swings and opens with one side of the handling chamber as a fulcrum. On the side opposite to the feed chain 4 side of the processing chamber 2, a second processing cylinder 7 for receiving a second processed material from the processing chamber and performing a grain removal process is parallel to the processing cylinder 3 and is inserted into the second processing chamber 8. It is built. A dust removal treatment cylinder 9 is installed in the dust removal treatment chamber 10 on the same axis as the rear of the second treatment cylinder 7.

  The handling chamber 2 is configured between the front side plate 2a and the middle side plates 2b and 2c, and the dust outlet 12 at the end of the handling chamber is formed between the middle side plates 2b and 2c. The handling cylinder 3 is extended rearward from the dust outlet 12 to form a fourth processing cylinder 3A, and a stab particle collection chamber 13 is formed between the middle plate 2c and the rear plate 2d.

  The swing sorting shelf 15 disposed below the handling chamber 2 is driven to swing back and forth by the swing crankshaft 14, and receives the processed product after the threshing process while swinging and transferring it. This is a configuration for sorting, and is arranged in the order of the transfer shelf 16, the first sheave 17, the second sheave 18, and the straw rack 19 from the upper side in the sorting direction, and the fine sorting is performed below the second sheave 18. The net 20, the first return shelf 21a, and the second return shelf 21b are arranged and provided.

In addition, a sorting chamber is configured below the swing sorting shelf 15 by providing a tang 22, a first spiral 23, a second spiral 24, and a dust exhaust fan 25 in order from the upper side of the sorting direction. Yes.
The first sheave 17 is disposed on the upper side from the lower side of the dust outlet 12 and includes a fixed sheave 26 in a fixed state that is inclined in the vertical direction with a predetermined interval in the front-rear direction. The second sheave 18 is disposed on the lower side of the dust outlet 12 and is configured to receive and sort the processed material from the first sheave 17 and the processed material from the stabbed grain collection chamber 13 and screen. The selection process is longer than that of one sheave 17 and includes a variable sheave 27 whose inclination angle changes.

  The first sheave 17 and the second sheave 18 are provided with cleaning plates 28 arranged in parallel to the front-rear swing direction of the swing sorting shelf and at predetermined intervals in the left-right direction, and upper surfaces of the fixed sheaves 26. A plurality of scrapers 30, 30, 30... Comprising a scraper 29 that contacts and removes deposits.

  Each scraper 30 of the first sheave 17 is interlocked so as to reciprocate horizontally in the lateral direction via an interlocking mechanism such as a reciprocating rocking arm 38 around the crank arm 35, the link 36, and the shaft 37 by the rotational drive of the drive motor 34. It is composed.

  In this embodiment, the drive motor 34 is integrated with the swing shelf, and the drive motor 34 and the link 36 are arranged in a blind spot between the transfer shelf 16 and the wind tunnel 22a of the tang 22. The structure is provided.

  As shown in the circuit diagram of FIG. 4, on the input side of the controller (control device) 40, a threshing clutch 41 that turns power transmission to the threshing device 1 on and off, and a threshing clutch switch that is turned on and off by turning on and off the threshing clutch 41. 42 and a pressure sensor (oil pressure sensor) 43 provided in an oil pump (not shown) of the engine E is connected, and a drive motor 34 for reciprocating the scraper 30 left and right is connected to the output side of the controller. ing.

  Therefore, when the engine E is started at the start of work, the oil pump for lubrication is driven to increase the oil pressure, and it is detected by the pressure sensor 43 that detects the oil pressure that the engine E is being driven. When the threshing clutch 41 is turned on and operated, each part of the threshing device is driven, and the swing sorting shelf 15 is also driven to swing in the front-rear direction. When the state where the engine E is driven is detected by the pressure sensor 43 and the threshing clutch switch 42 is turned ON due to the operation of turning on the threshing clutch 41, the controller 40 outputs the threshing clutch switch 42 to the drive motor 34. 30 will automatically operate. Further, when the threshing clutch switch 42 is turned off, the output to the drive motor 34 is automatically stopped (see the flowchart of FIG. 5).
