Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a net for a thresher mounted on the base of a harvester such as a combine harvester.

[0002]

[Prior Art]

 Conventionally, a threshing machine in which a catching net is arranged in the lower part of a handling room and a swinging sorting body is installed in a sorting wind passage formed by a windmill provided below a supply port is already known.

[0003]

[Problems to be solved by the device]

 Since the receiving net of the known threshing machine was fixed to the machine frame, threshing a grain culm that was wet or dewed resulted in a significant decrease in the leakage performance due to the clogging of the mesh with straw debris and overloading the handling barrel. At the same time, there was a problem that the grain was excessively carried around by the handling cylinder and damaged.

[0004]

[Means for Solving the Problems]

 The present invention is a threshing machine in which a receiving net is arranged in the lower part of a handling chamber, and a swinging sorting body is installed in a sorting wind passage formed by a windmill provided below a supply port. The swinging arm is suspended in the machine frame so as to swing in the front-back direction, and the receiving net is connected to a reciprocating drive device provided on the supply port side so as to vibrate in the axial direction of the handling cylinder. As a result, the leakage performance of the receiving network was improved and the aforementioned problems were solved.

[0005]

[Action]

 It is possible to mount the lamp and the mirror on a single bracket mounted on the cabin frame, and the lamp harness passes through the holes drilled in the cabin frame and on its sides and the notch in the bracket. Is configured in the harness installation space covered by the lamp support plate.

[Embodiment] The threshing machine shown in the drawings as an embodiment of the present invention will be described. Reference numeral 1 denotes a front-rear handling barrel axially mounted on a handling chamber 2, and a feeding port 3 is provided at a front portion of the handling chamber 2. Also, the rear part has an outlet port 5, a feed chain 6 and a sandwiching rail 7 are provided along the outside of the handling port 4, and a receiving net 8 is provided in the lower part of the handling chamber 2 and the lower part thereof is supplied. A blower wind turbine 10 provided below the mouth 3 and a suction wind turbine 12 provided on one side of the rear part of the dust sorting chamber 11 constitute a sorting wind passage. In this sorting wind passage, a stepwise transfer plate 13, The first sieve screening net 16 which is connected to the end and faces the first gutter 15, the second sieve sorting part 18 consisting of a straw rack facing the second gutter 17 and the transfer plate 13 and the first sieve sorting An oscillating sorting body 20 composed of a rough sorting section 19 facing the net 16 is erected so as to swing back and forth, and At the side of the separate chamber 11, a processing cylinder 22 having a front end communicating with a dust-sending port 21 at the rear of the handling chamber and having a processing net disposed around the processing cylinder 22 is mounted on the side, and the dust-selecting chamber 11 behind the exhaust port 5 is installed. Above that, a straw-transporting device 23 is provided.

Then, the outer ends of the pair of left and right support arms 25 and 26 fixed to both sides of the rear part of the net frame 8a of the net 8 are bent and hung down, and attached to the side wall on the handling port 4 side. An inverted L-shaped bracket 28 is screwed to the rear portion of the frame 27, and a pin 30 protruding from the inner surface of the bracket 28 and a pin 24 protruding from a plate 24a screwed to the support arm 25 are attached. A bracket 33 is attached to a frame 32 that supports the lower portion of a side receiving net 31 that covers the handling chamber 2 on the back side and that is connected to the swing arm 29 and hangs. The bracket 33 projects from the outer surface of the bracket 33. Since the pin 35 and the pin 36 projecting from the plate 36a screwed to the outer side surface of the support arm 26 are connected by a short swing arm 37, the rear portion of the receiving net 8 does not move much vertically. It is suspended so that it can vibrate back and forth. And

Further, a pair of left and right support plates 39, 39 are fixed to the front net frame 8a of the net 8, and the shaft rod 40 is attached to the nuts 41 ,. The fulcrum shaft 43 is rotatably supported by the projecting portions 42, 42 of the rearward U-shaped frame fixed to the inner surface of the front wall of the handling chamber 2, and the pair of arms 45 protruding from the fulcrum shaft 43 are provided. , 45, the shaft rod 40 is fitted in the notch groove 46, and the handle 40 side end of the shaft rod 40 is interlocked with the rear end of the rod 49 whose front end is connected to the eccentric cam 50. Although not shown, the eccentric cam 50 is rotatably driven by the front portion of the handling barrel shaft through a transmission device such as a chain and a bevel gear, whereby the receiving net 8 has an amplitude substantially equal to its mesh width. Shake back and forth with.

Then, the threshing machine described above is mounted on the combine stand, and the root portion of the harvested culm is inherited at the starting ends of the feed chain 6 and the picking rail 7 and the ear side is supplied to the supply port 3. Then, the handling cylinder 1 is shredded in the handling chamber 2, and the single-grained grains and small straw debris leaks from the receiving net 8 to the rocking sorting body 20 and is transferred to the sieve sorting and wind sorting. In response to this, the grain is carried out of the machine by the first transfer spiral in the No. 1 trough, and the fried grain cylinder is pumped and discharged, and the No. 2 grain is returned to the rocking sorter and re-sorted. .. If the grain culm is wet or dew is attached to it, the straw in the handling room 2 is likely to be clogged in the mesh of the receiving net 8, but the receiving net 8 vibrates back and forth as described above. It easily leaks together with the singulated grain and does not cause the above clogging. At that time, the lower end of the sickle frame 27 is close to the inner end of the flat portion of the support arm 25, and the downward bent portion of the upper end of the bracket 33 on the back side is bent upward of the support arm 26. Since the parts are fitted and covered from above, grain loss is not discharged from these parts.

[Effect of the device]

 The present invention relates to a threshing machine in which a receiving net 8 is arranged in the lower part of the handling chamber 2 and a swinging sorting body 20 is installed in a sorting wind passage formed by a windmill provided below the supply port 3, The left and right sides of the receiving net 8 are hung by swinging arms 29 and 37 so as to swing in the front-back direction on the machine frame, and the receiving net 8 is linked to a reciprocating drive device provided on the side of the supply port 3 and handled. Since it is configured to vibrate in the axial direction of the barrel 1, even if the grain culm to be threshed is wet or has dew attached to it, even if the grain debris in the handling room 2 is easily attached, the net By vibrating back and forth, the straw waste easily leaks from the mesh of the receiving net 8 together with the single-grained grains and the clogging of the receiving net 8 does not occur, and the handling cylinder 1 is overloaded. And it is possible to prevent the grain that has become a single grain from being excessively treated or secondly treated by the handling cylinder 1 and damaged. It can be long-lasting the normal of shedding process and selection process.
