Abstract

Since a processing cylinder is arranged at the rear of the threshing device and the processed material processed by the processing cylinder and the processed material processed by the processing cylinder are simply selected by the rocking sorter, grain loss has occurred. Try to improve further. Under the processing cylinder placed on the rear side of the threshing device, a carrier that receives the processed material processed by the processing cylinder and conveys it forward is placed, re-entered on the rocking sorter and re-sorted. The second product is transported to the front end of the swing sorting device by the second reduction conveyor, and the branch raft processing device is provided at the front end of the second reduction conveyor. Then, the processing cylinder and the conveyance body can be easily attached and detached to facilitate maintenance. In addition, the processing object falling from the front part of the transport body is detected by a sensor to prevent clogging.

Description

  The present invention relates to a technique for reducing a grain loss after threshing by providing a processing cylinder at the rear part of a threshing device in a combine. TECHNICAL FIELD OF THE INVENTION

Conventionally, in order to improve the threshing performance and sorting performance, a dust feed processing cylinder (processing cylinder) is arranged in parallel on the side of the rear part of the handling cylinder, and the branch stick attached grains that could not be processed by the handling cylinder are used as the processing cylinder. Of the grains that are fed and processed in the threshing section, normally 10-15% of the grains are made into a single grain and discharged through the processing net onto the swing sorting device of the lower sorting section.
Furthermore, the second thing after the grain is sorted by the sorting device from the grain and sawdust flowing down from the threshing part is again returned to the sorting start part of the swing sorting device via the second conveyor and the second reduction conveyor. I was trying to process it back. (For example, refer to Patent Document 1.)
Further, as the harvesting speed is increased, the sorting unit is also required to have a higher processing capacity (sorting capability), and measures such as clogging in the sorting unit are taken. For example, a technique for detecting the flow rate of waste in the waste chain and adjusting the opening of the chaff sheave in the sorting unit and increasing the opening of the chaff sheave when there are many objects to be processed is also known. (For example, refer to Patent Document 2.)

  However, if the amount of threshing processing increases due to the speed and efficiency of the combine unit, the processed material in the dust inlet processing cylinder will be rough, the filtration of the processing cylinder will be worsened, and the amount of emissions outside the machine will be reduced. Even if it increases or is filtered on a rocking sorter, the discharge from the third port to the outside of the machine increases without being filtered by a chaff sheave or the like, and it is difficult to achieve a normal single granulation rate. In particular, since many grains concentrate on the right side of the dust outlet processing cylinder, there is a possibility that the swing selection is poor.

In addition, there is a technique for adjusting the opening of the chaff sheave by providing a sensor for detecting the amount of the object to be deposited on the upper part of the sorting unit in the conventional combine. Since the sensor is located immediately behind the part where the untreated material is re-injected into the container (that is, closer to the dust feeding port processing cylinder than the center of the left and right of the sorting unit), the sensor is re-injected into the upper part of the sorting unit from the dust outlet. Before the processed object is evenly leveled by swinging on the sorting part, the sensor comes into contact with the sensor, and the sensor is actually not deposited so much on the upper part of the sorting part. In some cases, the workpiece was detected and the opening of the chaff sheave was excessively large. This increases the burden of wind sorting and may reduce the sorting accuracy of straw and sawdust.
In particular, in recent years, in order to increase the efficiency of the harvesting work by the combine, the traveling speed at the time of the harvesting of the combine has been increased, and there is a tendency that the amount of unprocessed material processed by the dust-feed port processing cylinder increases. . As a result, since the amount of work to be re-introduced from the dust transport conveyor to the sorting unit is large, it is important from the viewpoint of improving sorting capability to place the sensor at an appropriate position on the sorting unit. is there.

It is done.
A reed valve 65 is formed by the pair of handling cylinder case side reed valves 63 and the processing cylinder case side reed valves 64. The reed valve 65 has a predetermined reed angle (vector B perpendicular to the working surface of the reed valve 65) so that unprocessed materials are sent in the transport direction (arrow A in FIG. 6) by the rotation of the dust feeding port processing cylinder 22. And an angle formed with the vector A in the front-rear direction (arrow A)) (that is, substantially spiral) is provided in the upper half of the inner wall of the processing chamber 29.

As described above, by providing the reed valves 65, 65... Having the lead angle θ on the inner wall surface of the processing chamber 29, the processing chamber 29 is driven rearwardly (in the discharge direction) by the rotational drive of the dust-feed port processing cylinder 22. The conveyance of the untreated material is promoted, and the untreated material that has been conveyed from the handling chamber 28 to the processing chamber 29 through the dust feed port 23 moves quickly in the processing chamber 29. Accordingly, retention of unprocessed materials in the rear portion of the processing chamber 28 and the front portion of the processing chamber 29 (that is, in the vicinity of the dust feed port 23) and backflow of unprocessed materials from the processing chamber 29 to the processing chamber 28 are prevented. Sorting ability is improved.
In this embodiment, the reed valve 65 (the handling cylinder case-side reed valve 63 and the processing cylinder case-side reed valve 64) is disposed at the front of the processing chamber 29 where the dust feeding port 23 is provided. However, the present invention is not limited to this, and it may be provided in the middle or rear of the processing chamber 29 in accordance with the amount of unprocessed material generated.

Further, as shown in FIG. 6, the front end portion 63a of the handling case side reed valve 63 constituting the reed valve 65 and the rear end portion 64b of the processing case case side reed valve 64 are in the front-rear direction, that is, not seen. The unprocessed material that overlaps (overlaps) in the conveyance direction of the processed material and moves along the operation surface of the processing cylinder case-side reed valve 64 is surely brought into contact with the operation surface of the handling cylinder-side reed valve 63. Delivered. Therefore, although the reed valve 65 is divided into two members, it is possible to maintain a high conveyance capacity for unprocessed objects.
In the present embodiment, the handling case side reed valve 63 is parallel to the upper position of the processing chamber 29 from the upper end of the dust feeding port 23 in a side view, and is substantially the same as the handling chamber 28 from the front end of the dust feeding port 23. It is provided up to the rear end position. In addition, the processing cylinder case-side reed valve 64 is provided in parallel from the upper and lower middle portions of the dust feeding port 2 to the upper position of the processing chamber 29, from the front end of the dust feeding port 23 to the substantially rear end position of the dust feeding port 23. Thus, the dust can be reliably transferred from the dust supply port 23 into the processing chamber 29.

Further, regarding the size of the lead angle θ, the length L1 from the rear end portion 63b of the handling case side reed valve 63 to the front end portion 64a of the processing case case side reed valve 64 in the unprocessed material conveyance direction is: It is preferable that the opening width L2 of the dust feeding port 23 in the unprocessed material conveyance direction is half or more (L1 ≧ (1/2) × L2).

If the lead angle θ is excessively large, the friction between the working surface of the reed valve 65 and the unprocessed material becomes excessive, increasing the load related to the rotational drive of the processing cylinder 22, and causing causes such as degassing and crushing of the soot It may become. Therefore, it is necessary to appropriately select the lead angle θ according to the use conditions of the combine.

  6, partition plates 66, 66,... Having no lead angle .theta. (.Theta..apprxeq.0) from the central portion of the processing chamber 29 away from the dust feed port 23 to the rear portion are formed on the inner wall of the processing cylinder case 62. As shown in FIG. Is provided. In this way, from the central part to the rear part of the processing chamber 29, the unprocessed material is rather hindered from being quickly conveyed to the rear, and is separated and sorted (filtered) by performing sufficient separation and sorting.

By the two-stage process of the dust-feed port processing cylinder 22 and the second processing cylinder 78, branch sticking grains are reduced, and the reprocessing distance of the degranulated material of the handling cylinder is secured to increase the sizing. It becomes possible.

In the present embodiment, the gear externally fitted to the front end portion of the rotary shaft of the dust feed conveyor 50 and the gear fitted to the front end portion of the rotary shaft of the dust feed processing cylinder 22 are engaged with each other. The ratio of the rotational speed of the dust feeding / conveying conveyor 50 and the rotational speed of the dust feeding port processing cylinder 22 is configured to be substantially constant. Accordingly, the amount of the object to be processed that is separated by the dust supply processing cylinder 22 and captured by the dust transfer conveyor 50 and the amount of the object to be transferred forward by the dust transfer conveyor 50 are set at a predetermined ratio. Can be maintained. It should be noted that the rotational speeds of the dust feeding / conveying conveyor 50 and the dust feeding port processing cylinder 22 such as gears, belts and pulleys, chains and sprockets on the rear end side of the rotating shafts of the dust feeding / conveying conveyor 50 and the dust feeding port processing cylinder 22 The driving force may be distributed while maintaining the ratio substantially constant.
An object to be processed that has passed through a hole (net opening) provided in the processing drum net 24 and dropped downward is forward of the machine body by the dust feeding conveyor 50 (that is, the conveying direction of the dust feeding drum processing drum 22). It is conveyed toward the opposite direction. Then, the object to be processed is reintroduced into the sorting unit 17 through the dust discharge port 50a provided at the front end of the dust feeding and conveying conveyor 50. More specifically, the object to be processed falls on the chaff sheave 33 to a position above the cereal board 39 (that is, above the first conveyor 36).
In this embodiment, the dust transport conveyor 50 is a screw type conveyor, but is not limited to this, and may be a belt type conveyor. Further, the position where the object to be processed is re-input by the dust feeding / conveying conveyor 50 may be on the upstream cereal board 30.

Hereinafter, the sensor 51 will be described with reference to FIGS. 5, 25, and 26.
The sensor 51 detects the amount of waste accumulated on the front cereal plate 30 and the chaff sheave 33 provided in the upper front part of the sorting unit 17 and adjusts the opening degree of the chaff sheave 33. 51a and the sensor part 51b.
The contact body 51a is an elongated plate-like member, and one end thereof is attached to the rotation shaft of the sensor unit 51b. The sensor unit 51b is a rotation angle sensor such as a resolver, a rotary potentiometer, or a rotary encoder, and can detect the attitude of the contact body 51a with respect to the machine body in the form of an angle.

As shown in FIG. 26, the vertical thickness T [mm] of the object to be processed (mixture of soot and shredded swarf) deposited on the chaff sheave 33 is high from the upper surface of the chaff sheave 33 to the sensor unit 51b. The length H [mm], the length R [mm] of the contact body 51a, and the rotation angle φ [rad] of the contact body 51a detected by the sensor unit 51b, 0 <T <H− when φ = 0. When R and φ> 0, it can be expressed as T = H−R × cos θ. Note that the rotation angle φ of the contact body 51a is zero when the contact body 51a is facing downward (when it is not in contact with the object to be processed), and the contact body 51a is in contact with the object to be conveyed rearward. Then, it is defined as taking a positive value when it is rotated backward.
On the other hand, within the range in which the swarf and soot can be separated with high precision in the sorting unit 17, the amount of fall from the chaff sheave 33 to the grain sheave 32 is increased as much as possible, and the opening degree of the chaff sheave 33 and the object to be processed are maximized. The relationship with the thickness T [mm] in the vertical direction of the object (mixture of slag and shredded swarf) is obtained in advance by experiments or the like.
Then, the opening degree of the chaff sheave 33 is adjusted based on the information on the rotation angle φ from the sensor 51 (that is, information on the amount of deposition of the object to be processed on the chaff sheave 33 and the upstream cereal board 30).

  For example, in the case where the object to be processed is deposited in a mountain shape only under the sensor 51 and is not deposited in any other place on the chaff sheave 33 or the front-flow cereal board 30, it is detected by the sensor 51. The thickness T [mm] obtained from the rotation angle φ to be measured does not correctly reflect the actual deposition amount of the workpiece on the chaff sheave 33 and the front flow grain board 30 (in this case, the actual deposition amount). The amount of deposition will be estimated more than that). Accordingly, the fact that the object to be processed is evenly distributed on the chaff sheave 33 and the upstream cereal board 30 is also viewed from the viewpoint of efficiently performing the selection from the viewpoint of accurately obtaining the thickness T [mm]. Even important.

Actually, the workpieces are evenly leveled on the chaff sheave 33 and the front-flow cereal plate 30 due to the swinging of the sorting unit 17, but only under the dust outlet 50 a at the front end of the dust feeding conveyor 50, In particular, when the traveling speed at the time of harvesting is high (a large amount of the harvested product is thrown into the threshing unit 12 and the sorting unit 17 per unit time), the workpieces that have fallen from the dust outlet 50a accumulate in a mountain shape. There is a case.
Therefore, the mounting position of the sensor 51 is a position slightly away from a local “mountain” generated by the workpiece to be re-input into the sorting unit 17 by the dust feeding / conveying device 50, and is attached by the dust feeding / conveying device 50. It is preferable that the workpiece to be re-entered into the sorting unit 17 and the workpiece to be dropped after passing through the receiving net 20 are mixed at a position where they are evenly mixed by swinging.

As shown in FIG. 5 and FIG. 25, in this embodiment, the rotation axis of the handling cylinder 21 is closer to the left side than the center of the sorting unit 17 (left and right center line CC shown in FIG. 25), The rotation axis of the mouth processing cylinder 22 is shifted to the right side. Accordingly, the dust feeding conveyor 50 that conveys the object to be processed generated in the dust feeding port processing cylinder 22 also has its rotating shaft closer to the right side than the left and right center of the sorting unit 17, and the sorting unit from the dust outlet 50 a. The object to be processed falling on 17 forms a mountain 70 at a position on the right side of the left and right center of the sorting unit 17.
The sensor 51 is located behind the fuselage 50a of the dust feed conveyor 50 (that is, downstream of the sorting unit 17 in the conveyance direction of the object to be processed) and from the left and right center of the sorting unit 17 to the handling cylinder 21. It is arranged closer. Therefore, the detected value of the amount of the object to be processed deposited on the sorting unit 17 is not greatly deviated from the actual accumulated amount due to the influence of the crest 70, and the sorting unit is moved by the dust feeding / conveying conveyor 50. The amount of the object to be processed is detected at a position where the object to be re-input to 17 and the object to be processed that has passed through the receiving net 20 are mixed by swinging and are evenly distributed. Therefore, it is possible to detect the accumulation amount of the object to be processed with high accuracy.
Note that the position of the sensor 51 is (1) behind the machine body (ie, downstream of the sorting unit 17 in the conveying direction of the object to be processed) from the dust outlet 50a of the dust feeding conveyor 50, or (2) the handling cylinder. Even if it is arranged below the rear part of 21 and closer to the handling cylinder 21 than the center of the left and right of the sorting part 17, the same effect can be obtained.
In the present embodiment, the sensor unit 51b of the sensor 51 is a rotation angle sensor such as a resolver, a rotary potentiometer, or a rotary encoder. However, the present invention is not limited to this, and the contact unit 51a is configured by using the sensor unit 51b as a contact switch. Alternatively, the switch may be turned on / off when the switch rotates more than a predetermined angle. Further, a capacitance sensor or the like may be used.

  A guide plate 81 is disposed behind the transport body 50. As shown in FIGS. 12 to 14, the guide plate 81 is disposed below the processing cylinder 22 and above the swing sorting device 27. The front end position of the guide plate 81 is disposed in front of the rear end of the processing cylinder 24, and the rear end position of the guide plate 81 is disposed rearward of the rear end of the swing sorting device 27. Is formed. The guide plate 81 is disposed between the suction fan 25 and the processing cylinder cover 76 so as to be approximately equal to the width of the processing cylinder 22 in the left-right direction, and is fixed by fixing means such as bolts.

  The guide plate 81 guides the dust and the like inside the dust feed processing cylinder 22 to the outside of the machine body. The guide board 81 splashes the waste inside the processing cylinder 22 by the rotation of the wings 91 and 91, and the processing cylinder. 22 and is guided to the outside of the machine body by the guide plate 81. Thus, by providing the guide plate 81, the sawdust can be discharged outside the machine body without being mixed into the transport body 50 and the swing sorting device 27. The installation of the guide plate 81 is an arbitrary matter and may function as a combine even if it is not installed.

  By arranging a processing cylinder at the rear part of the handling cylinder of the threshing apparatus, arranging processed grain or dust forward by the carrier below the processing cylinder, and arranging a branch raft processing apparatus in front of it, wheat It can be used for the purpose of improving the performance of threshing and selecting grains such as rice and rice.
