Description

Detailed Description of the Invention [Industrial Application Field] The present invention provides an axial center along the grain culm conveyance direction at least below the conveyance path of the grain culm which is held and conveyed in a horizontally suspended position by a feed chain. A large number of handling rotors that are driven and rotated around each other are arranged side by side in the grain culm direction with their rotation trajectories overlapping each other, and the rotation direction of each handling rotor on the grain culm transport path side is set toward the grain culm tip side. The present invention relates to a threshing device in which a grain sorting filter material is installed along the lower side of a group of handling rotors on the lower side of a grain culm conveyance path.

[Problem that the invention seeks to solve]

The threshing device having the above configuration is configured so that the handling rotary body not only acts directly on the grain culm, but also massages the processed material separated from the grain culm with a filter material to promote the single graining of the processed material. Since the processed material on the filter medium is sent toward the feed chain while being rubbed by the handling rotor on the lower side, an opening is formed on the upper surface of the filter medium toward the feed chain for discharging the unfiltered material. is normal. When these openings are formed in the filter material, there is a problem that the processing area for filtration and massaging action is reduced.Also, if the openings are made small to solve this problem, the processing material containing coarse materials such as long straw can be removed. This caused problems in the discharge of water.

The present invention has been made in view of the above-mentioned problems, and it can be applied to the filtration material by rational modification of the device, without reducing the processing area of the filtration material or reducing the processing capacity. It is an object of the present invention to provide a threshing device that can smoothly discharge unfiltered matter.

[Means for solving problems]

The present invention is characterized in that receiving teeth are provided protrudingly on the upper surface of the filter material and overlap with the rotation locus of the handling rotor, and a discharge port for unfiltered matter is formed on the feed chain side of the filter material. In addition, a sorting space is provided below the feed chain to receive the discharged material from the discharge port, and its functions and effects are as follows.

[Function] In other words, in order to provide the sorting space as described above and form the discharge port for unfiltered matter in communication with this space, the discharge port can be formed at the end of the filter material on the feed chain side. This makes it possible to avoid reducing the processing area of the filter medium. In addition, since this space is formed on the handling port side, by forming a vertically communicating gap on the side of the feed chain, it becomes possible to recover the processed material if it scatters from the handling port. In addition, since the receiving teeth are provided in a protruding manner as described above, when the processed material on the filter medium is rubbed by the lower handling rotating body, it is subjected to a shearing action between the receiving teeth and the handling rotating body, making it difficult to shed particles. Even the processed material is strongly shed, and the processed material on the filter medium is prevented from moving in the feed chain direction by the receiving teeth, and the time spent being rubbed between the handling rotating body and the filter material is extended. Become.

〔Effect of the invention〕

Therefore, the space below the feed chain, which is originally a dead space, is effectively used to create a space, a discharge port is formed to communicate with this space, and a receiving tooth is provided protruding from the top surface of the filter material, making the device large. It also enables the formation of a large discharge port without causing any damage or reducing the processing area of the filter medium, allowing untreated substances on the filter medium to be discharged smoothly without being obstructed. A threshing device with improved processing capacity has now been provided.

In addition, in the case of a threshing device consisting of a group of upper and lower handling rotors, the processed material may be sent to the handling port side by the upper group of handling rotors, and if the processed material is scattered from the handling port, By forming a gap in the side portion of the feed chain that vertically communicates with the space, the loss of the processed material is reduced and the recovery rate is improved.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

The threshing device will be described in detail based on FIGS. 1 and 2. In the handling chamber A where the grain culms are fed in a horizontally suspended position in the feed chain 1, four handling rotors 2, which are driven and rotated around an axis along the grain culm transport direction, are positioned below the grain culm transport path. It is being constructed. The handling rotary body 2 is composed of a drive shaft 3, a drum 4, and handling teeth 5 protruding on three sides when viewed in the axial direction, and handles grain culms and supplies them to the upper part of the two groups of rotors, and handles and rotates the grains. body 2
Threshing is possible by driving and rotating each of them toward the grain culm tip side.

A filter material 6 is disposed below the handling chamber A and has a portion corresponding to the middle of the handling rotors 2, 2 formed into a convex convex mountain shape so as to be close to the rotation locus of the handling teeth 5.

The filtering material 6 is made of a plate-like material and has a large number of through holes 6a. In addition, the receiving teeth 7 protrude into the filter medium 6 so as to be positioned below the respective handling rotors 2 and to fit between the front and rear handling teeth 5 so as to overlap the rotation locus of the handling teeth 5. The filter material 6 and the handling teeth 5 are installed so that the processed material can leak out.
The grains are crushed between them and made into single grains, and the processing is accelerated by the action of the receiving tooth 7 and the handling tooth 5 in the shearing direction.

Feed chain 1 of the thresher and the opposite side wall 8a
A receiving tooth 7 is provided protruding from the inside of the handling chamber in the same manner as that attached to the filter medium 6.

A side wall 8b of the threshing device on the side of the feed chain 1 is located outside the feed chain 1, and a space S extending below the feed chain 1 and the filter medium 6 is formed. Further, this space S communicates vertically through the side portion of the feed chain 1, and also communicates with the handling chamber A through the side edge of the filter material 6, and this communication portion is referred to as a discharge port T. and,
Since this discharge port T can be formed relatively large, unfiltered matter on the filter medium 6 can be smoothly discharged.

A swing sorting section 9 is provided below the filter medium 6 and the space S, and further below there is a winnower 10 for sending sorting air, a No. 1 screw 11 for collecting grain culms, and a No. 1 screw 11 for collecting grain culms. A No. 2 screw 13 is provided which returns the dust to the handling room A by means of a swallow 12, and a dust exhaust fan 14 is provided on the lower side in the grain culm conveying direction at the upper part of the swing sorting section 9, thereby reducing the amount of filtering material. The grains are collected from the processed material supplied from the exhaust port 6 and the discharge port T, and floating dust generated during sorting can be sucked and discharged by a dust exhaust fan 14.

[Another example]

As shown in FIG. 3, the present invention can also be applied to a grain culm conveyance path formed between two groups of lower handling rotors and two upper groups of handling rotors, and in particular, a threshing device with this configuration. In this case, the processed material is sent toward the handling port U by the two groups of handling rotors located above, and scattering is likely to occur from the handling port U. In this case, the processed material is scattered through the communication section above the space S It becomes possible to collect things.

In addition, in this embodiment, the swing sorting section was arranged below the space, but instead of this, the present invention has a wall body facing downward from the opening edge of the discharge port on the filter medium side. The space below the material may be separated from the space, and the material to be processed from the discharge port may be supplied to the reprocessing section via a rack or the like without being supplied to the swing sorting section. It may also be supplied to the processed material recovery section. Further, the processing capacity may be improved by arranging a processing cylinder within the space so as to powerfully process the processing material from the discharge port.

Further, in this embodiment, the opening area of the discharge port is fixed at a constant value, but instead of this, a sliding type, hinge type, or other type of lid body is provided at the opening so that the discharge port area can be adjusted. This may be implemented so as to suppress the movement of the processed material near the discharge port and enhance the rubbing action between the filter material and the handling rotor.
