DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to an improvement of a handling threshing machine.

2. Description of the Related Art Conventional threshing machines, regardless of whether they are an upper handling type or a lower handling type, the receiving net in the handling room is, as it were, an essential component of the handling room, and is installed opposite to the handling barrel. The thresher that has been threshed in the first half of the handling room is transferred to the exit of the handling room while stagnation inside the handling room due to the spiral arrangement of the handling teeth that are planted in the handling barrel. Most of the crushed grains leak from the net. And, in the case of a threshing section structure having only a handling cylinder with a receiving net opposite thereto and having no processing cylinder, the handling room generally has a shedding action to separate grains from the culm and a cutting grain or a branch adhering grain. It is designed to perform both of the processing functions of making the untreated material into single particles.

Problems to be Solved by the Invention As described above, in the handling chamber opposite to the receiving net, both the shedding action and the treating action are performed by the rotation of the handling cylinder and the cooperation of the receiving net. Not only does the load on the handling room increase, but if the leakage rate of the receiving net worsens, the grains after shedding do not leak from the receiving net and are transferred to the outlet side of the handling chamber while stagnating in the handling chamber. As a result, the number of damaged grains and the number of third loss grains increased, and the number of clam grains increased. In particular, when threshing a wet material or the like, the above-described inconveniences are compounded because the separation of grain and straw waste becomes poor, and the material easily adheres to the net or the like and becomes clogged.

Means for Solving the Problems Therefore, the present invention is an upper handling type threshing machine in which the grain culms are supplied to the upper side of the handling chamber on which the handling barrel is mounted to thresh, and the lower side of the handling barrel is handled. It is opened over the entire length in the cylinder transfer direction, and a pair of processing cylinders parallel to the processing cylinder are rotatably arranged side by side in a single processing chamber below the processing chamber. It is possible to solve the above-mentioned problems by configuring the processing cylinder on the side in the same direction as the rotation direction of the handling cylinder and the rotation direction of the processing cylinder on the lower side opposite to the rotation direction of the handling cylinder. In addition to moving the unprocessed object especially under the handling cylinder very smoothly, highly efficient processing can be achieved, and the space between the handling cylinder and the processing cylinder can be set to be small, enabling a compact and compact body structure. It is what

Action After the grain culm is supplied to the handling room of the upper threshing machine and threshed,
The grain-removed grains fall directly onto the processing cylinder below the handling chamber, and are processed while being sequentially transferred to the processing cylinder end side by the processing cylinder. At this time, unprocessed materials such as cuttings and particles attached to branch shoots generated in the handling room are washed away in the handling room by the rotating force of the handling cylinder and the wind of the handling cylinder. A processing cylinder that rotates in the same direction as the handling cylinder is arranged on the upper side of the rotation direction, and rotates in the opposite direction to the handling cylinder on the lower side of the rotation direction of the handling cylinder (hereinafter also referred to as normal wind rotation).
Since the processing cylinder is disposed, the unprocessed material can be moved extremely smoothly below the handling cylinder.

Example 1 is a handling room of an upper handling type threshing machine, 2 is a handling barrel rotatably mounted in the handling chamber, and this handling barrel 2 has a front portion, that is, a handling chamber inlet 2a side, and a rear portion, that is, a handling chamber outlet 2b side. High front low rear high. 1a is a drain plate provided on the tip side of the handling room 1,
The water dewatered in the handling chamber 1 at the time of threshing the wet material is discharged from the small hole 1'a of the drainage plate 1a and then led out of the machine through a guide passage (not shown). . 3 is a feed chain and 4 is an exhaust straw chain. By the way, the lower side of the handling cylinder 2 is open as shown in FIGS. 1 and 3, and this part is an open part 5 having no receiving net. A pair of processing cylinders 6 and 7 (double processing cylinders) are arranged below the handling chamber 1 in parallel with the handling cylinder 2 and in an inclined state extending to the rear of the machine body. With this double processing cylinder configuration, etc., the processing capacity is improved, the outside diameter of the processing cylinder can be reduced, and the height of the body can be set as low as possible. Due to the slanted arrangement, the vertical spacing of the sorting unit, which will be described later, can be widened and a good sorting action can be maintained. As shown in the drawing, the processing cylinders 6 and 7 have spiral transfer portions 6a and 7a directly below the processing cylinder 2, and the rear portion of the processing cylinder 2 has processing teeth a on the outer circumference of the spiral transfer portions 6a and 7a. The processing units 6b and 7b are formed by being planted in a spiral shape with the same pitch. Further, the processing cylinders 6 and 7 are closely opposed to each other in a state where the respective processing teeth a are a bitingly overlapped with each other.

On the other hand, the processing cylinders 6 and 7 are not symmetrically positioned with respect to the virtual vertical line 1 of the handling cylinder shaft 2'a, but are slightly biased toward the lower hand side (the handling mouth 2'b side) in the rotational direction of the handling body 2. The processing cylinders 6 and 7 are arranged in a state (see FIG. 3).
Among them, the processing cylinder 7 on the upper side in the handling cylinder rotation direction rotates in the same direction as the handling cylinder, and the processing cylinder 6 on the lower side in the handling cylinder rotation direction rotates in the opposite direction to the handling cylinder.

Now, of the pair of processing cylinders 6 and 7, one processing cylinder 6
The end portion of the processing cylinder (the one located away from the suction fan 8 in the illustrated example) is extended to the rear side of the machine body with respect to the other processing cylinder 7, and the dust outlet 9 is provided on the extension block b side.
Below the processing cylinders 6 and 7, the spiral transfer portions 6a and 7a are provided.
The bottom plate 10 provided with a large number of drainage holes 10a to the extent that the grain does not leak, and the leaking bodies 11 continuous with the bottom plate 10 are provided corresponding to the processing units 6b and 7b. There is. Reference numeral 12 is a guide plate for discharging the water droplets dropped from the water drain hole 10a of the bottom plate 10 to the outside of the machine. 13 is a swinging sorting body which constitutes the sorting unit 14, 15 is Kara Tan, 16 is 1
No. spiral, 17 is No. 2 spiral, and 18 is auxiliary Kara. 19
Is a No. 2 reduction cylinder, and its upper end discharge port 19a is made to face a stepped swinging reduction body 20 which is swingably arranged above the processing chamber C. The transferred second product such as a cutting piece is discharged onto the oscillating reducing body 20 and then dispersed and transferred together with the fourth product which has dropped onto the oscillating reducing body 20, and from the end portion thereof to the processing cylinder. It has been reduced to 6, 7 and reprocessed. Reference numeral 21 is a processing chamber upper plate, 22 is an oscillating body for returning a leaked substance, and 23 and 24 are adjusting tools.

FIG. 4 and FIG. 5 show another embodiment, in which the processing teeth a are spirally provided around the entire length of the processing cylinders 6 and 7, and the processing stroke for an unprocessed object is shown. Can be made longer, and the processing performance can be further improved.

In the above-mentioned configuration, the threshed grains (including grains, cuttings, adhering twigs, straw waste, etc.) threshed in the handling room 2 are handled in the handling room 1
After being dropped from the open portion 5 onto the spiral transfer portions 6a and 7a of the processing cylinders 6 and 7 without swirling the inside, they are quickly spirally transferred to the rear processing portions 6b and 7b. And the processing unit 6b,
In 7b, untreated materials such as cuttings and branches attached particles are treated tooth group a.
After being subjected to singulation while being sequentially transferred to the rear of the processing chamber c by, the leaked body 11 together with the shell grains that were shed in the handling chamber 1
Leaks and falls into the lower sorting section 14 for sorting processing.

By the way, the untreated materials such as the cuttings of the spikes and the particles attached to the branch shoots generated in the handling room 1 are caused by the rotating force of the handling body 2 and the action of the handling body wind.
In the present invention, the processing cylinder 7 disposed in the upper direction in the rotation direction of the handling cylinder 2 is flowed to the lower procedure in the lower rotation direction of the handling cylinder.
Is configured to rotate in the same direction as the handling cylinder 2, and the processing cylinder 6 arranged in the lower procedure of the handling cylinder rotation direction is configured to rotate in the opposite direction to the handling cylinder 2. In the portion, the processing teeth a rotate upward from below in a state where they are overlapped with each other as shown in FIGS. 2 and 3, and these teeth flow under the handling cylinder 2. It also serves to lift the processed material. For this reason,
The unprocessed material is transferred to the processing cylinder 6 on the lower side in the direction of rotation of the handling cylinder very smoothly without being scratched between the processing cylinders 6 and 7, and an efficient processing operation is performed.

Straws and the like are rectified by the rear wall C'of the processing chamber on the terminal side of the processing chamber and directed in the direction orthogonal to the processing cylinder while passing through the opening d and provided on the extension b side of one processing cylinder 6 It is smoothly discharged from the 9 out of the machine. Generally, at the end of the handling chamber or the end of the processing chamber, the shell grains are likely to be scattered to number 3 due to the turbulent repulsion. Combined with this, the loss of shell grains due to No. 3 scattering is prevented as much as possible. In addition, since the processing cylinders 6 and 7 are configured to be long, the processing stroke of the processing object becomes long,
The processing performance is further improved. By the way, in the present invention, since there is no receiving net in the handling room 1 unlike the conventional one, clogging of the receiving net in the handling room is eliminated, and any inconvenience caused by this clogging, that is, the handling room receiving net The clogging of the pellets reduces the leakage rate of the shredded shell grains, which makes the retention time of the shell grains longer in the handling chamber, increasing the number of damaged and lost grains, frequent clam grains, and the load on the handling chamber. The inconvenience of increasing the number is eliminated at once. Furthermore, when threshing the wet material, the water dewatered by centrifugal separation in the handling chamber 1 passes through the small holes 1'a of the water draining plate 1a or the water draining holes of the bottom plate 10 below the processing cylinders 6, 7. Since it is discharged to the outside of the machine through 10a, the adaptability of the wetting material is further enhanced.

Effect of the Invention As described above, the present invention is an upper-handling thresher in which husks are supplied to the upper side of the handling chamber on which the handling barrel is mounted and threshing, and the lower side of the handling barrel is used. Open over the entire length in the transfer direction, a pair of processing cylinders are rotatably arranged side by side in a single processing chamber below the processing chamber, and the processing cylinder is located on the upper side in the rotation direction of the processing cylinder among the pair of processing cylinders. Since the direction of rotation of the cylinder is the same as the direction of rotation of the handling cylinder, and the direction of rotation of the processing cylinder located on the lower side is opposite to the direction of rotation of the handling cylinder, the burden on the handling room is large. In addition to alleviating various inconveniences caused by clogging of the net such as increase in damaged grains and loss grains, increase in clam grains, etc. Due to the cooperation of the processing cylinders, the unprocessed material that has flowed under the handling cylinder is transferred to the middle part of the processing cylinder. In this case, since each processing tooth floats up from below, the unprocessed object is smoothly transferred to the processing cylinder on the lower side in the rotating direction of the processing cylinder without being trapped and accumulated between the processing cylinders. The unprocessed material can be moved extremely smoothly downward, an efficient processing operation can be performed, and the size and size of the machine body can be reduced.
