Description

Combine {COMBINE}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a technique for providing a treatment copper at a rear side of a threshing apparatus relating to a combine, and to reduce the loss of grain particles after threshing. It relates to the description of the carrier.

Conventionally, in order to improve threshing performance and sorting performance, a rosin ball processing cylinder (processing cylinder) is arranged in parallel from the rear side of the barrel, and the grain-attached particles, etc., which are not processed in the barrel are sent to the processing cylinder, and the threshing unit is processed. In the grains treated in the above, 10 to 15% of the grains are usually granulated and discharged onto the shaking screen sorting device in the lower sorting section through the processing network.

In addition, the second object after sorting the grain particles from the grains and straw powder flowing down from the threshing unit is returned to the screening start portion of the swing screening apparatus through the second conveyor and the second reduction conveyor for processing. (See Patent Document 1, for example.)

In addition, as the harvesting speed is increased, the sorting unit also requires higher processing capacity (selection capacity), and measures for preventing clogging in the sorting unit are also required. For example, a technique is known in which the flow rate of the discharge straw in the discharge straw chain is detected to adjust the opening degree of the chaff sheave of the sorting part and to increase the opening degree of the chaff sheave when there are many objects to be processed. See 2.)

However, if the threshing throughput is increased due to the high speed, high efficiency, etc. of the combine main unit, the processed material of the rosin port treatment ridge becomes coarse, and the filtration of the processing network is deteriorated. Emissions increased from the third port to the outside without being filtered through the sieve or the like, making it difficult to achieve a normal granulation rate. In particular, since a large number of grain particles are concentrated and concentrated underneath the rosin port treatment dong, there has been a case of causing a disturbance in screening.

      In addition, there is a technique for providing a sensor for detecting the amount of the workpiece to be deposited on the upper part of the sorting unit in the conventional combine, and adjusting the opening degree of the chaff sieve, but there is a dust discharge port (selection part in the sorting unit) Since the sensor is arranged immediately behind the re-input part (i.e., the east side of the sorting port rather than the left and right centers of the sorting part), the object to be re-injected from the dust exhaust port to the upper part of the sorting part is equalized by shaking on the sorting part. Even though the sensor contacts the sensor before being evenly selected, and the amount of the workpieces actually deposited on the upper part of the sorting unit is not so large, the sensor detects the workpieces and the opening of the chaff sheave may be excessively large. This may increase the burden on the balloon and reduce the sorting accuracy of the nucleus and rice straw powder.

In particular, in recent years, in order to increase the efficiency of the harvesting operation by the combine, the running speed during the harvesting operation of the combine is increased, and there is a tendency that the amount of untreated matters processed by the rosin port treatment wing increases. As a result, since there is a large amount of the workpiece to be re-injected from the rosin conveying conveyor, it is important from the viewpoint of improving the sorting capability to arrange the sensor at an appropriate position on the sorting section.

It is provided below the true-gut treatment dong, and is equipped with the conveying body which accommodates the process material discharged from the rosin-processing ward, and conveys it forward, All the conveying bodies are arrange | positioned on the front-back middle part of a barrel rear part, and the oscillation screening apparatus, In the front of a conveyance body, the ear branch processing apparatus provided in the front end of the 2nd reduction conveyor is arrange | positioned so that a processed material may fall on all the shaking-separation apparatuses.

A combine having a threshing portion and a sorting portion for sorting grains after threshing, wherein a barrel is disposed in the threshing portion, and a rosin treatment tube for reprocessing the threshing grains is disposed at a rear side of the threshing portion. A treatment material discharged from the rosin treatment ward is received below the mouth treatment duct, and the treated matter is conveyed in a direction opposite to the conveying direction of the threshing particles by the rosin treatment ridge to be discharged onto the swing sorting device of the sorting unit. The first gear is provided in the process cylinder boss which connects a process cylinder drive shaft and a process cylinder, and the 1st sprocket which drives a conveyance body is coaxial with the 2nd gear meshed with the said 1st gear. And a conveyance body is driven by the 2nd sprocket which cooperates with a said 1st sprocket.

The said carrier body provided in the lower part of the said rosin port process cylinder is attached so that attachment or detachment is possible toward the back of a base body.

The shaft end of the drive shaft in the front side of the said carrier body is supported by the spline coupling with respect to the said 2nd sprocket, and can be attached or detached to the back of the body only by the removal of the carrier body rear.

The removal is performed together with the bearing frame of the carrier.

In addition, in the combiner provided with the barrel condensed in the front-rear direction of a base body, the rosin port processing cylinder arrange | positioned at the back part of the said barrel, and the rosin conveying conveyor arrange | positioned under the rosin port processing cylinder and conveying forward,

A sensor for detecting the amount of the workpiece deposited on the upper part of the sorting unit is disposed behind the dust exhaust port of the rosin conveying conveyor.

The sensor which detects the quantity of the to-be-processed object deposited on the said sorting part is arrange | positioned below the barrel rear part, and is arrange | positioned toward the barrel rather than the left-right center of a sorting part.

Effect of the Invention

By the above configuration, the unprocessed material which has not been processed in the barrel is sent to the rosin port treatment ridge for processing, and the processed matter which is processed in the rosin port processing ridge and dropped from the process ridge network is sent forward by the carrier to the oscillation screening device. It is reselected by this, and balloon sorting is performed again by a tuft, and processing efficiency can be improved, grain particle loss can be reduced, and the sorting width of a sorting apparatus can be utilized effectively. And since the ear branch processing apparatus is located in front of it, the processed material processed by the ear branch processing apparatus and the processed object by the rosin port processing copper do not overlap on the rocking | fever sorting apparatus, respectively, and cause clogging. There is no phenomena such as this, and it can select with high efficiency.

Since the conveyance direction end part of a conveyance body is located in the gas advancing direction front side rather than the said end part of the said barrel on the said sorting part, it is below the part where the leakage of the process material which falls from a water net by the desorption action by a barrel is reduced. The treatment is introduced, the leakage is not biased, and the treatment efficiency can be improved by effectively using the width in the front-rear direction of the sorting section. In addition, the rotational direction of the carrier is a direction in which the processed material is discharged onto the sorting section from below to upward, so that the conveyed processed material is not discharged to the shaking sorting device while being knocked on the shaking sorting device. The particles do not deteriorate and are dispersed and hardened by being thrown upwards, so that the screening efficiency can be improved because the particles do not fall on the rocking screen.

The right root is provided in all the discharge parts of the carrier, and since the right root is configured to be discharged to the left and right central axes of the swing sorting device, the processed material is blown to the swing sorting device side by the right root so that the swing sorting device Can be emitted across the width direction.

Since the ear branch processing device is connected to the conveying end of the carrier, the ear branch processing can be performed with high efficiency, and there are many straw pieces in the processed material by the rosin port processing copper, but it can be crushed by the ear branch processing device. As a result, the screening ability can be improved.

The untreated material not processed in the threshing part is smoothly (naturally) guided to the rosin port by the guide plate from the rear portion of the threshing part to the entire rosin port treatment ridge. In the rosin port treatment ward, the treated material is conveyed forward by the carrier, and the treated material discharged from all of the carriers reaches the diffuser plate, diffuses and falls on the rocking separator, so that it does not become solid and clogged. Can improve.

Moreover, since the ear branch processing apparatus provided in the front-end | tip part of the 2nd reduction conveyor was arrange | positioned in front of a conveyance body, and the processing object was made to fall on all the shaking-separation apparatuses, the 2nd object processed by the shaking-separation apparatus was rocked and sorted. It can be processed by the ear branch processing apparatus before feeding back into the apparatus, so that the grain particles with the ear branch can not be circulated again and again, thereby increasing the number of grain particles and improving the sorting efficiency.

After the gear shift, power is transmitted to the carrier by the sprocket and the chain, and power can be transmitted by the simple configuration, and the carrier can adjust the position at the transmission part by the sprocket and the chain. It can absorb.

Since the carrier body is configured to be detachably attached to the rear of the body, the shaft frame is separated from the edge of the water tank at the stage of replacement or cleaning of the carrier body, and the spline inlet on the drive shaft side is separated from the fitting hole on the second sprocket side. The whole conveying body can be taken out from the upper part of a water tank. In addition, since the detachment is performed together with the bearing frame of the carrier, the disassembly of the bearing, the part which fixes the bearing, and the like are unnecessary, and the detachment is easily performed so that the assembly order and the direction are not wrong.

In addition, since the sensor for detecting the amount of the workpiece deposited on the sorting unit is placed behind the dust outlet of the rosin conveying conveyor, the detected value of the amount of the workpiece deposited on the sorting unit falls from the rosin conveying conveyor. The treated material immediately after the end of the work is not greatly reduced from the actual amount of deposition, and the processed material dropped back through the water tank and the water reintroduced into the sorting unit by the rosin conveying conveyor By detecting the amount of the workpiece at a position uniformly evenly mixed by the shaking, it is possible to detect the amount of deposition of the workpiece with high accuracy.

Since the sensor for detecting the amount of the workpiece deposited on the upper part of the sorting part is disposed below the barrel rearward and is steered toward the barrel than the left and right centers of the sorting part, the detection value of the amount of the workpiece deposited on the sorting part is transferred from the rosin conveyance conveyor. The object to be processed immediately after the drop does not actually fall far from the deposition amount, and the object to be dropped back from the rosin conveying conveyor to the sorting unit and the object dropped through the barrel of the barrel are shaken. By detecting the amount of the workpiece at the position where it is mixed and evenly uniformly, it is possible to detect the deposition amount of the workpiece with high accuracy.

This hangs over, and the 2nd process network 79 with a fine mesh hangs below the 2nd process cylinder 78, and hangs.

The jingugu treatment dong 24 is reprocessed while the water duct communicates with the rogue port 23 of the barrel 21 and sends degassed particles of the barrel 21 to the rear of the gas, and the filtration passes through the process network 24. Water is discharged onto the second treatment cylinder 78. The second treatment cylinder 78 is reprocessed while sending the filtrate from the rosin mouth treatment cylinder 22 to the front of the gas, and the treatment object is shaken through the second treatment network 79 and the shaken separator 27 ) Is then reduced onto the shake screening shaker 49. The two-stage treatment of the rosin ball treatment cavity 22 and the second treatment cylinder 78 reduces the number of particles attached to the branch, and also ensures that the reprocessing distance of the degranulation of the barrel is secured, thereby increasing the number of crystal grains. It becomes possible.

In addition, in the present embodiment, the gear wheel wound around the front end of the rotary shaft of the rosin conveying conveyor 50 and the gear wheel wound around the front end of the rotating shaft of the rosin port processing cylinder 22 are engaged with each other, It is comprised so that ratio of the rotation speed of 50) and the rotation speed of the rosin port process cylinder 22 become substantially constant. Therefore, the quantity of the to-be-processed object isolate | separated from the rosin port process wing 22 and captured by the rosin conveyance conveyor 50, and the quantity of the to-be-processed object conveyed forward by the rosin conveyance conveyor 50 can be maintained at a predetermined ratio. Further, on the rear end side of the rotation shaft of the rosin conveying conveyor 50 and the rosin port processing ridge 22, the rosin conveying conveyor 50 and the rosin port processing ridge 22, such as a cogwheel, a belt and a belt car, or a chain and a sprocket. The driving force may be distributed while maintaining the rotational speed ratio of ().

The to-be-processed object which passed down through the hole (net nose) provided in the processing network 24 by the said rosin conveyance conveyor 50 is gas front (namely, the reverse direction of the conveyance direction of the rosin port process cylinder 22). Conveyed toward. Then, the object to be processed is re-injected into the sorting unit 17 in the dust exhaust port 50a provided in front of the rosin conveying conveyor (50). More specifically, the to-be-processed object falls on the chaff sheave 33 so that it may be located above the grain plate 39 (that is, above the No. 1 conveyor 36).

In addition, in this embodiment, the rosin conveyance conveyor 50 is a screw type conveyor, It is not limited to this, A belt type conveyor may be sufficient. In addition, the position where the to-be-processed object is re-injected by the rosin conveyance conveyor 50 may be on the current curved board 30. FIG.

Hereinafter, the sensor 51 will be described with reference to FIGS. 5, 25, and 26.

The sensor 51 is for detecting the amount of discharged rice straw deposited on the current curve plate 30 and the chaff sheave 33 provided at the top of the sorting part 17, and for adjusting the opening degree of the chaff sheave 33, It mainly consists of the contact body 51a and the sensor part 51b.

The contact part 51a is a long thin plate-shaped member, and one end is attached to the rotating shaft of the sensor part 51b. The sensor part 51b is a rotation angle sensor, such as a resolver, a rotary potentiometer, a rotary encoder, etc., and can detect the attitude | position of the contact body 51a with respect to a gas in the form of an angle.

As shown in FIG. 26, the thickness T [mm] of the up-down direction of the to-be-processed object (mixture of the piled up and shredded rice straw) deposited on the chaff sheave 33 is a sensor part 51b on the chaff sheave 33 upper surface. When φ = 0 by the height H [mm] up to), the length R [mm] of the contacting body 51a and the rotation angle φ [rad] of the contact body 51a detected by the sensor unit 51b. When 0 <T <HR and φ> 0, it can be represented by T = HR × cosθ. In addition, the rotation angle φ of the contact body 51a is set to 0 when the contact body 51a is directly downward (when not in contact with the object to be processed), and the contact body 51a is conveyed backward. It is defined as having a correct value when contacting the workpiece and rotating back.

On the other hand, within the range capable of separating rice straw and nuits in the sorting unit 17 with high accuracy, the chaff sheave 33 has the maximum amount of fall from the chaff sieve 33 to the grain sieve 32, and the sorting processing capacity is maximized. ), The relationship between the opening degree and the thickness T [mm] of the vertical direction of the object (a mixture of the piled and shredded rice straws) is determined in advance through experiments or the like. The opening of the chaff sheave 33 is based on the information on the rotation angle φ from the sensor 51 (that is, the information on the deposition amount of the workpiece on the chaff sheave 33 and the current curved plate 30). Adjust the degree. For example, in the case where the workpieces are deposited in the form of a mountain only under the sensor 51 and not deposited in the chaff 33 and other places on the current curved plate 30, the sensor 51 is detected by the sensor 51. The thickness T [mm] obtained from the rotation angle φ does not necessarily correctly reflect the deposition amount of the workpiece on the chaff sheave 33 and the current curve plate 30 (in this case, the deposition amount is larger than the actual deposition amount). With many estimates). Therefore, from the viewpoint of obtaining the thickness T [mm] with high accuracy, the object to be processed is evenly distributed on the chaff sheave 33 and the current curve plate 30 in terms of high efficiency. It is also important to see.

In reality, the object to be processed is uniformly formed on the chaff sieve 33 and the current curved plate 30 due to the shaking of the sorting unit 17, but only below the dust outlet 50a in front of the rosin conveying conveyor 50. Particularly, when the traveling speed during harvesting is large (a large amount of crops are fed into the threshing unit 12 and the sorting unit 17 per unit time), the workpieces dropped from the dust exhaust port 50a are deposited in a mountain form. There is a case.

Therefore, the mounting position of the sensor 51 is a position away from the extreme 'mountain' generated by the object to be re-injected into the sorting unit 17 by the rosin conveying conveyor 50, and the rosin conveying conveyor ( It is preferable that the to-be-processed object which is re-injected into the sorting unit 17 by 50) and the to-be-processed object which passed through the water network 20 are mixed by shaking, and it is arrange | positioned evenly and evenly.

As shown in Figs. 5 and 25, in this embodiment, the rotation axis of the barrel 21 is biased to the left side rather than the left and right centers (left and right center lines CC shown in Fig. 25) of the sorting unit 17, The axis of rotation of 22) is biased to the right. Therefore, in the rosin conveyance conveyor 50 which conveys the to-be-processed object which arises in the rosin-out process building 22, the rotation axis is also oriented to the right side rather than the left-right center of the sorting part 17, The to-be-processed object which falls on the sorting part 17 forms the mountain 70 in the position which shifted to the right rather than the left-right center of the sorting part 17. FIG.

The sensor 51 is located behind the gas back (ie, downstream of the conveying direction of the object in the sorting section 17) and the left and right sides of the sorting section 17 than the dust exhaust port 50a of the rotatable conveying conveyor 50. It is arrange | positioned by the barrel 21 rather than the center. Therefore, the detection value of the amount of the workpiece to be deposited on the sorting unit 17 does not become a value deviated greatly from the actual deposition amount under the influence of the acid 70, and the rosin conveying conveyor 50 The amount of the object to be processed is detected at a position where the object to be re-injected into the sorting unit 17 and the object to be dropped through the water network 20 are mixed and shaken evenly and evenly evenly to be processed, thereby providing a high accuracy. It is possible to detect the amount of deposition of water.

In addition, the position of the sensor 51 is (1) the back of a gas (that is, downstream of the conveyance direction of a to-be-processed object in the sorting part 17) rather than the dust discharge port 50a of the conveyance conveyance conveyor 50, or (2 The same effect can be obtained even if the rear side of the barrel 21 is arranged to satisfy one of the biased portions of the barrel 21 rather than the left and right centers of the sorting unit 17.

In addition, 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 thereto, and the sensor unit 51b is a contact switch. When the sieve 51a is rotated more than a predetermined angle, the switch may be turned on or off. In addition, a capacitive sensor or the like may be used.

Doing. The guide plate 81 is disposed between the suction pan 25 and the processing cylinder cover 76 approximately equal to the width of the processing cylinder 22 in the horizontal direction, and is fixed by fixing means such as a bolt. have.

The guide plate 81 guides rice straws, etc., inside the rosin bowl treatment dong 22 to the outside of the body, and splashes rice straws inside the processing dong 22 by the rotation of the right bodies 91 and 91. It raises and discharges below the process cylinder 22, and guides it out of a base by the said guide plate 81. As shown in FIG. By providing the guide plate 81 as described above, rice straw can be discharged to the outside of the gas without being mixed in the carrier 50 or the rocking separator 27. In addition, installation of this guide plate 81 is arbitrary, and it may function as a combine even if it is not installed.
