行ない得るようにせんとする点にある。[Detailed description of the invention] The present invention is a reaping threshing machine equipped with a reaping husk conveying device that changes the reaped husk culm from a standing position to a sideways position and transports and supplies the reaped husk culm to a threshing section. Regarding reaping and threshing equipment such as combine harvesters, in which a reaped husk culm transport device is installed between the husk and the rear-mounted threshing unit, the purpose is to remove the reaped husk from the outside or upper side of the reaped husk transport device during harvesting and threshing work. Supplying hand-cut culms to the threshing section on headlands, etc. by effectively utilizing safety covers to prevent accidental insertion of hands, etc., and ensure safety for workers and operators at all times. The aim is to make work easier.

先ず、本考案の実施例を図面に基づいて詳述する。First, an embodiment of the present invention will be described in detail based on the drawings.

る。Figure 1 shows a combine harvester, which engages a clipper-type reaping device 1A and the stock base of a planted culm near the ground in front of the reaping device 1A, and pulls it up and conveys it upward to the rear of the machine. Between the reaping section 1, which consists of a pulling device 1B, and the threshing section 2, which is mounted on the rear of the machine, the stock base of the culm, which has been cut in a vertical position, is held between the legs of the threshing section 2. The stock clamping and conveying device 3A transports the stock to the chain 2A, and locks the tip of the cut husk culm in an upright position and transfers it to the threshing section 2.
A reaping culm conveying device 3 consisting of a tip locking and conveying device 3B for transporting the reaping culm to the culm supply port 2b of A safety cover 4 made of sheet metal is provided to cover the lateral outside and upper side of the shell culm conveying device 3, and the upper part 4A of this safety cover 4 is connected to the shell culm supply port 2b of the threshing section 2 for hand-cut shell culms on a headland, etc. (see the opening in Figure 2), the safety cover is formed on a horizontal or substantially horizontal surface at the same or approximately the same level as the culm conveying surface 2A of the feed chain 2A. The lower end 4b of the side portion 4B of 4,
In order to allow the stem portion of the cut culm held and conveyed by the stem clamping and conveying device 3A to protrude laterally and outwardly (see the opening in Figure 2), it is swung and rotated laterally outwardly via a hinge or the like. It can be configured freely.

している。Further, as shown in FIG. 3, the reaped husk culm conveying device 3 is supported via a support member 7 on a horizontal shaft 6 which swingably supports the support frame 5 so as to be swingable up and down. The handling depth can be adjusted by changing the position of the gripping point at the starting end of the conveyance up and down, and the horizontal axis 6 The culm supply port 2b of the threshing section 2 is located at the tip of the link 8 that swings around the axis.
An auxiliary guide plate 9A is pivotally mounted to be slidable along the grain culm guide plate 9 provided at The angle is such that the distance between the conveying end portion of the cut husk culm conveying device 3 and the starting end portion 9a of the auxiliary guide plate 9A can be maintained constant or approximately constant regardless of vertical swinging due to depth adjustment. It is set.

に利用することができるに至ったのである。In summary, the reaping and threshing machine with a safety cover according to the present invention has a safety cover 4 that covers the lateral outside and upper side of the reaped husk culm conveying device 3 installed between the reaping section 1 and the threshing section 2 mounted at the rear. During reaping and threshing work, it is possible to reliably prevent hands, etc. from accidentally being inserted from the lateral outside or upper side of the reaped husk culm conveying device 3, and to ensure safety for workers and operators at all times. However, in particular, the present invention is configured so that the upper portion 4A of the safety cover 4 doubles as a feeding table for the hand-cut husk to the threshing section 2, so that it is not possible to use the hand-cut IJ l on headlands etc. ) When feeding the culm to the threshing section, -
This eliminates the need for labor and installation structure such as installing a dedicated supply stand for each, and the upper portion 4A of the safety cover 4 can be effectively used as a supply stand.

勢で手抜ぎ作業をしなければならない。Moreover, in order to avoid the stock side of the conveyed culm, which would normally fall down on its side, the safety cover bulges outward significantly, so the cover is placed on the hand-cut culm supply stand. Even if the worker tries to use the threshing section 2 as a tool, he or she must stand at a distance from the threshing section 2 and do the work in a cramped position with his hands outstretched.

に手抜ぎ脱穀ができる。However, in the present invention, the part 4b of the safety cover 4 facing the stock side of the conveying shell culm is configured to be able to swing open and close, so the safety cover 4 can be provided close to the conveying device 3. When threshing by cutting corners, the worker can safely and comfortably do the threshing.

また、前記安全カバー４の機械的強度を、一連に形成さ
