Threshing in which grain is stored in a grain tank juxtaposed to the side of the threshing machine via a fryer cylinder from the gate, and the reduced kernels are fed back to the rocking sorting body from a port No. 2 via a reduction cylinder. Machines are known. The threshing machine of this threshing machine and the reduction cylinder are installed in the installation space formed between the threshing machine wall and the grain tank. Are separated from each other and stand upright toward the upper grain tank.

[0003]

According to the above-mentioned conventional construction, the fryer cylinder which is erected in an upright position is provided in parallel in a front view so as not to come into contact with the reduction cylinder. There is a disadvantage that the installation space of the machine becomes large, and the grain tank protrudes to the outside of the machine body from the threshing machine to increase the machine body width. In addition, if the width of the machine is to be reduced, the width of the grain tank becomes narrow, and there is a problem that the storage capacity of the grain is reduced. Therefore, the present invention solves the above-mentioned conventional problems, without increasing the width of the machine or reducing the storage capacity of the grain tank, while reducing the size of the machine and discharging the grain, and reducing the second reduced product. An object of the present invention is to provide a threshing machine for a threshing machine which can favorably carry out the reduction and transport of ash.

[0004]

In order to achieve the above object, according to the present invention, the first opening 11 and the second opening 9 are provided at the front and rear positions below the swing sorting body 8 installed along the handling room 6. The grains are stored in the grain tank 5 juxtaposed to the side of the threshing machine 1 from the first port 11 via the fryer cylinder 12 and the reduced grains are stored from the second port 9 via the reducing cylinder 10. In the threshing machine 1 which carries out the reduction transport toward the front side of the swinging sorting body 8, in a side view
The above-described reduction cylinder 10 is provided in a front inclined shape crossing the frying cylinder 12.
And the reduction cylinder 10 is a threshing machine wall 1a in a front view.
Along the inside of the base of the above-mentioned frying cylinder 12
2 is an extension line 10c whose upper inner surface 12d is outside the reduction cylinder.
It stands in an inwardly inclined shape so as to be more inside.

[0005]

According to the above configuration, the fryer cylinder 12 is mounted on the threshing machine wall 1.
a, while ensuring a sufficient space for the reduction cylinder 10 to pass therethrough, without passing the reduction cylinder 10 into contact with the inside of the base of the fry cylinder 12, Can be provided along the threshing machine wall 1a. Also, the upper part of the fryer cylinder is inclined inwardly toward the threshing machine 1 so as to be inclined.
By making the inner side surface 12d cross the inside of the extension line 10c outside the reduction cylinder 10, the upper part of the graining cylinder 12 is brought close to the threshing machine 1, and the grain tank 5 and the threshing machine 1
The grain tank 5 and the threshing machine 1 can be installed close to each other while making the space formed between them as narrow as possible, without increasing the body width of a traveling work machine such as a combine on which the grain tank 5 is mounted. The size can be reduced.

[0006]

An embodiment of the present invention will be described with reference to the drawings. A threshing machine 1 equipped with the device of the present invention is mounted on a machine base 4 which is provided with a mowing unit (not shown) and a driver's seat 2 and travels on a crawler traveling device 3. A combine for performing harvesting and threshing work by arranging a grain tank 5 such as a hopper tank is arranged. This threshing machine 1 handles a culm harvested and transported from a reaping section by a handling cylinder 6 a in a handling chamber 6.
In addition, threshing is performed by the processing cylinder 7a in the processing chamber 7 provided on the rear side of the handling chamber 6, and threshing is received by the rocking sorter 8 disposed below these, and rocking sorting is performed.

[0007] By the above-mentioned swing sorting operation, the second product in which straw chips and the like are mixed in the grain is transferred from the spiral shaft 9 a in the second opening 9 to the reduction cylinder 10 and is sent to the swing sorting body 8. In addition to carrying out the re-sorting process and the re-sorting process, the first product which is not mixed with straw waste or the like is a hoisting spiral 12a connected to the end of the spiral shaft 11a in the first opening 11.
Is roasted in a roasting cylinder 12 rotatably housed therein, and discharged into the grain tank 5 from a discharge port 12b formed at the upper end thereof. In addition, cut straws, wastes, and the like are discharged from a dust opening port opened behind the threshing machine 1. The grains contained in the grain tank 5 can be discharged to an appropriate place outside the machine by operating a series of grain discharging mechanisms (discharge spirals) 13 when the grains are full.

The mounting structure of the reduction cylinder 10 and the fry cylinder 12 and the positional relationship between the two are configured as shown in FIGS. That is, the reduction cylinder 10 is attached to the second port 9 such that the base of the spiral shaft 10a rotatably supported inside the reduction cylinder 10 is lower below the second spiral shaft 9a , Threshing machine wall 1a so as to be close to the side and pass through the inside of the threshing machine so as to have a forwardly inclined shape crossing the fryer cylinder 12 in a side view.
And a return port (discharge port) 10b formed at the upper end thereof
Are fastened and fixed to the threshing machine wall 1a with mounting screws 14. The return cylinder 10 in the embodiment is inclined obliquely in the forward direction so that the second product can be returned and thrown from the discharge port 10b toward the front side of the leading end of the swing sorting body 8, and Since the dynamic re-sorting is sufficiently provided, the sorting can be performed satisfactorily.

In addition, when viewed from the front, the hoisting cylinder 12 has a base having a space sufficient to allow the reduction cylinder 10 to pass between it and the threshing machine wall 1a via the transfer cylinder 12c between it and the first port 11. While ensuring that the upper side thereof is inwardly inclined toward the threshing machine 1 so that the inner side surface 12d of the fryer cylinder 12 intersects the extension line 10c outside the reduction cylinder 10 inside. ing. Then, the above-mentioned fryer cylinder 12 in the embodiment is brought as close as possible to the machine wall 1b of the processing chamber 7 formed by bulging from the machine wall 1a of the threshing machine 1 to the grain tank 5 side. Each part is effectively installed while narrowing the space formed between the grain tank 5 and the threshing machine 1 by moving the upper part of the throat to the threshing machine 1 side. In a threshing machine in which the above-mentioned processing chamber 7 does not protrude toward the grain tank 5, the frying cylinder 12 may be provided directly near the reduction cylinder 10.

[0010] With the above structure, the grain tank 5 is installed close to the threshing machine 1, so that it is possible to reduce the size of the machine without increasing the machine width and to manufacture an inexpensive combine with good workability. I have. A transmission case 15 for rotating and driving a processing cylinder 7a supported in the processing chamber 7 includes a pulley 1 having a pulley 15a provided on a blower fan rotation shaft 16.
From 6a, a belt 17 is stretched to transmit rotation. Further, the transmission case 15 is fixed to the machine wall 1b so as to protrude in a state of approaching the upper side of the reduction cylinder 10, and the outside of the transmission case 15 separated from the threshing machine wall 1a and the upper half of the reduction cylinder 10. Connecting rod (connection member) 18
Are linked by

As a result, the reduction cylinder 10 in the forwardly inclined posture is fixed to the machine wall 1a on both sides of the base and the discharge port 10b, and the middle of the reduction cylinder 10 is further moved to the transmission case 15
, The reduction cylinder 10 tilted forward has a helical shaft 10a.
The rigidity is high and strongly supported against the rotation and vibration of the machine body, and the vibration of the reduction cylinder 10 is suppressed, the vibration damage of the machine wall mounting portion is prevented, and the lifting cylinder 12 installed in the vicinity is installed. It accurately prevents contact with the user. Especially transmission case 1
5 and the reduction cylinder 10 are integrally connected to each other.
Since the transmission case 15 is reinforced and supported by 0, the transmission case 15 that is likely to be fluctuated when the processing cylinder 7a is under a high load can be stably fixed.

In the above-described supporting structure, the reduction cylinder 10 and the transmission case 15 are connected to each other in the vertical direction by the connecting member 18 at a position separated laterally from the threshing machine wall 1a in a state where they are close to each other. Strong support can be provided at a low cost with a simple configuration. Further, the reduction cylinder 10 can be effectively used as a mounting member for a component constituting a nearby transmission mechanism such as a processing cylinder transmission mechanism described below. That is, a support arm 19b for supporting the tension pulley 19 of the belt 17 is attached to a lower portion of the firmly fixed reduction cylinder 10 by using a spring 19 as a mounting member.
A pressure is applied at a and the pivot is pivotally supported so that the proper position of the belt 17 can be stably pressed by the forward inclined posture of the reduction cylinder 10. Incidentally, reference numeral 20 denotes the belt 2 from the fan rotation shaft 16.
1 is a driving pulley of the handling drum 6a transmitted through the first pulley 1;

[0013]

According to the present invention, the reducing cylinder is provided along the machine wall in a front-slant shape crossing the raising cylinder through the inside of the base of the raising cylinder. The upper part of the reduction cylinder is inclined so as to be inside the extension line of the outside of the reduction cylinder, so that the reduction cylinder and the lifting cylinder can be juxtaposed without contact between the grain tank and the threshing machine, The grain tank and the threshing machine can be mounted on the traveling work machine as close to each other as possible, minimizing the size of the machine and reducing the size of the machine, and running a low-cost combine with good performance. A working machine may be provided.

[0014] Further, the fryer is provided with an inward inclination on the threshing machine side, so that the discharge port formed at the upper end can be easily opened slightly upward. This has the advantage that grains can be efficiently filled into the inner part of the grain tank.
