Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a grain culm feeding device for a combine harvester that performs threshing processing by inheriting the root of the harvested grain culm from the end of the vertical transport chain of the mowing section by the feed chain and horizontally transporting the grain in the yard. It is a thing.

[0002]

[Prior Art]

 Conventionally, when harvesting and threshing culms with combine harvesters, it is labor-intensive and labor-intensive because the corners of the field are hand-cut and the feed is fed to feed chien. It also depends.

[0003]

[Problems to be solved by the device]

 As described above, even in the case of conventional combine harvesting and threshing work, the corners of the field must be hand-cut, which requires labor and time, and the present invention does not require this hand-cutting work. In order to save the labor and time required for cutting, as shown in "Fig. 3", when cutting the corners, the cutting part is raised to a level that does not hit the ridge, and is cut to a very short culm. The whole amount of harvested culm is supplied from the entrance of the handling room into the handling room for processing.

[0004]

[Means for Solving the Problems]

 Therefore, in order to solve the above-mentioned problems, the present invention proposes, in the combiner described at the beginning, to position the end portion between the end of the vertical transport chain and the start end of the feed chain so that the end portion is formed. A conveyor chain was installed diagonally toward the center of the handling room entrance, intersecting the feed chain, and the entire amount of ultra-short culm grain culms was supplied to the handling room by the transport chain. In addition, it is preferable that this transport chain be configured to interlock with the raising and lowering operation of the reaper, and that the grain culm transport speed be synchronized with the feed chain sandwich transport speed.

[0005]

[Action]

 With this configuration, the conveyor chain is stored in the lower jaw to make it inactive, the cutting unit is set to the normal cutting height position, the aircraft is advanced, and the planted grain culms are cut and the harvested grain culm roots are harvested. When the end of the vertical chain is transferred from the end of the chain to the end of the feed chain, the tip of the chain is fed laterally through the handling room to perform threshing treatment. With the transport chain in this state activated, raise the reaper to a level that does not hit the ridge as shown in "Fig. 3" and perform high mowing. Then, the harvested grain culms that have become ultra-short culms due to the high cutting are inherited from the end of the vertical transport chain to the start end of the transport chain, and are transported toward the center of the handling room entrance due to the change in the transport direction. The whole amount of grain culm is supplied to the handling room and threshed.

Further, in this case, if the transport chain is linked to the raising and lowering operation of the mowing unit, the relative position between the end of the vertical transport chain and the start end of the transport chain does not change, and the succession action of the harvested culm is obtained. If the feeding speed of the grains of the transport chain is synchronized with the sandwich transport speed of the feed chain, the feed chain sandwiches the roots of the stockers and the heads of the chains are fed laterally into the room. When carrying out threshing treatment, this transport chain carries the stalks of the cut grain culm to the handling room entrance while aligning the roots of the harvested ears to the tips of the ears, and the supply of the ears to the handling room is not delayed.

 Hereinafter, the grain culm feeder according to the present invention will be described with reference to an embodiment diagram. As shown in FIG. 2, this combine (6) is a traveling chassis installed on a traveling device (7), and (A) is a fiber frame. -A threshing part that is installed on the traveling chassis (6) with the dochien (2) stretched to the left side and incorporating the handling cylinder (8), swing sorting body (9), etc., (B) is the grass body (10)・ Mowing unit (C) provided in the preceding stroke of the threshing unit (A), which comprises a raising case (11), a cutting blade (12), a vertical transport chain (1), a tip transport tine (13), etc. Is a straw processing unit that looks into the end of the straw chain (14), (D) is a control unit, and (15) is the grain from the threshing unit (A), which is stored through the frying tube (16). This is a grain tank that continuously cuts the planted grain culms and feeds the harvested grain culms to the vertical transport chain (1) and the tip transport tines (13). Then, the threshing section (A) conveys it to the crocodile, holds the crocodile with the feed chain (2), and supplies the tip of the crocodile from the handling room inlet (4) into the handling room (3) for lateral transport. Threshing is performed, and while the grains are stored in the grain tank (15), the threshed straw is carried out by the straw chain (14) and processed by the straw processing unit (C).

Further, the mowing section (B) is provided with a mowing lifting lever () provided on the control section (D) with the input shaft for supplying power to each part of the mowing section (B) as a pivot point (P). 17) The hydraulic cylinder device (18) is constructed so that it can be raised and lowered by moving the rod (19) of the device (18) forward and backward, and its pivot point (P) is the starting end of the feed chain (2). It is located near the gutter.

Next, (20) is an inlet iron plate extending forward from the handling room inlet (4) between the threshing section (A) and the mowing section (B), and (5) of the present invention. The transport chain (5) is a main part, and the transport chain (5) has its starting end located between the turning end of the vertical transport chain (1) and the starting end of the feed chain (2). The terminal portion is obliquely provided so as to face the central portion of the inlet (4) of the handling chamber and is intersected with the feed chain (2). The transport chain (5) is supported at its starting end by a support member (21) projecting from the back surface of a guide member for guiding the circulation of the vertical transport chain (1), and the support member (21) is used as a fulcrum for the support chain. It is possible to change from the working state looking into the slot (22) provided in the entrance iron plate (20) to the non-working state in which the lower part pivots to the side and is housed, and the cutting and raising lever (17) is It is designed to interlock with the raising and lowering operation of the reaper (B) by operation.

Further, (23) is a sandwiching rod opposite to the upper side of the transport chain (5), and the handling chamber inlet (4) is vertically moved around the waving point as a fulcrum to face the transport chain (5). It is possible to switch between the state and the state of retracting upward. Then, the conveying chain (5) is supported by a supporting member (21) projecting from the rear surface of the longitudinal end of the longitudinal conveying chain (1) to drive the starting end portion of the longitudinal conveying chain (1) to drive power from the longitudinal conveying chain (1). Although input, the grain culm conveying speed (V1) is set so as to be synchronized with the sandwiching conveying speed (V2) of the feed chain (2). Further, the power supply to the transport chain (5) may be transmitted by means such as a flexible wire (24) or the like from the beginning of the feed chain (2).

Since the transport chain (5) changes the transport direction of the high-cut ultrashort culm grain culms from the transport direction of the feed chain (2), the transport chain of the feed chain (2) is changed. A certain distance (W) is provided from the starting end of the transport chain (5) so that the starting end does not act on my ultra short culm.

Therefore, as shown by the phantom line (a), the transport chain (5) is housed in the lower side to make it inactive, and the holding rod (23) is retracted upward (b). Then, the cutting section (B) is set to the normal cutting height position, and the machine is advanced to cut the planted grain culms. The plant origin of the harvested grain culms is cut off from the end of the vertical transport chain (1). The starting end of the dochien (2) is passed to the crocodile and the ears of the dochien are sent laterally through the handling room (3) for threshing treatment. However, when approaching the corner of the field, the transport chain in the inactive state ( 5) is made to look into the slot 22 of the inlet iron plate 20 from below to change it from the non-acting state to the working state, and the pinching rods 23 which are retracted upward are transferred to the conveying chain 5). Switch to the opposite position on the upper side of the plant and hit the mowing section (B) against the ridge (25) as shown in "Fig. 3". Raise it to the extent that it does not exist and mow it high. Then, the culm culms that have become ultra-short culms due to the high cutting are transferred from the end of the vertical transport chain (1) to the start end of the transport chain (5), and are inherited by the trap bar (23) to the entrance to the handling room. It is transported to the central part of (4) and the whole amount of grain culms is supplied into the handling room (3) and threshing is performed.

[0013] Further, when the roots of the stock are sandwiched by the feed chain (2) and the tips of the roots are laterally fed through the handling room (3) for threshing, the transport chain (5) is connected to the inlet iron plate ( 20) When the pinch bar (23) is evacuated to the upper side of the groove hole (22), the grain transfer speed (V1) of the transfer chain (5) is the feed chain (V1). Since it is synchronized with the feeding speed (V2) of (2), the feeding chain (5) arranges the stalks of the harvested grain culm as if the roots of the stalks were combed into the stalks and the entrance to the handling room (4). ) And the supply of the tips to the inside of the treatment room (3) will not be delayed.

[0014]

[Effect of the device]

 As described above, according to the present invention, since the end of the vertical conveying chain (1) of the cutting section (B) is cut off, the stock grain of the cut grain culm is taken over by the feed chain (2) to the handling room (3).
