Description

  The present invention relates to a processed product leakage structure of a threshing apparatus that leaks a processed product obtained by threshing processing by rotation of a handling cylinder.

  As the processed material leakage structure of the threshing apparatus as described above, a receiving net is configured by screwing a support frame and a bow to a steel plate having a large number of eye holes, and the mesh that becomes the mesh of the receiving net There exists what made the processed material obtained by the threshing process leak from a hole (for example, refer patent document 1).

Also, a first steel material and a second steel material having a substantially U-shaped cross-sectional view provided as a linear steel material, a rod-shaped steel material, a first linear steel material, a second linear steel material, and an arc-shaped member having a circular cross-sectional view. The first member to the fifth member prepared as above are arranged in a predetermined arrangement and welded to each joint portion to form a lattice-shaped receiving net, and the processed material obtained by the threshing process is leaked from the mesh of the receiving net. (For example, refer to Patent Document 2).
JP 2000-92971 A (paragraph numbers 0015 to 0016, FIGS. 1 to 5) JP 2001-61333 A (paragraph numbers 0017 to 0019, FIGS. 1 to 12)

  In recent years, the amount of processing per unit time tends to increase as work speeds up. Therefore, it is necessary to increase the leakage area of the receiving net and promote the leakage of the processed material obtained by the threshing process by rotating the handling cylinder, but there is also a limitation on the arrangement space of the receiving net Therefore, it is difficult to secure a large leakage area corresponding to the speeding up of work by enlarging the receiving network.

  As a result, as work speeds up, the grains are easily damaged by being subjected to the threshing process by rotation of the handling cylinder without being leaked from the receiving net while being made into single grains.

  An object of the present invention is to prevent damage due to poor leakage of single grains without increasing the size of the receiving net.

  In order to achieve the above object, in the invention according to claim 1 of the present invention, it is formed so as to be curved along the outer periphery of a handling cylinder that is rotationally driven with a support shaft as a fulcrum. A receiving net is provided so as to cover the lower side from below, and in a frame portion located on the lower side in the rotational direction of the handling cylinder in the receiving net, the processed material obtained by the threshing process by the rotation of the handling cylinder A leakage hole that allows leakage is formed.

  According to this characteristic configuration, the leakage obtained by the threshing process by rotation of the handling cylinder is formed not only from the mesh of the receiving net but also on the frame portion located on the lower side in the rotational direction of the handling cylinder in the receiving net. It will also leak from the hole. That is, the leakage area can be increased without increasing the size of the receiving network, and the leakage of the processed material can be promoted.

  In addition, the treatment hole is not a frame part located on the upper side in the rotation direction of the handling cylinder in the receiving net that tends to be in a state where the treatment object is accumulated, but the treatment object is scraped up and diffused with the rotation of the handling cylinder. Since it is formed on the frame part located on the lower side in the rotation direction of the handling cylinder in the receiving net that is likely to become damaged, the mass of the treated material is larger than that of cut straw or straw scraps. It is possible to particularly promote the leakage of single-grained grains that are easily affected by centrifugal force due to the accompanying rotation from the leakage hole.

  Therefore, it is possible to secure a large leakage area corresponding to the speeding up of work without increasing the size of the receiving network, thereby increasing the throughput due to the speeding up of work and leakage of single grains. Can be promoted, damage caused by poor leakage of the single grain can be prevented, and as a result, the quality of the grain can be improved together with the recovery efficiency of the single grain.

  In particular, during the threshing process, the harvested cereal rice cake is squeezed by the pinch conveyance mechanism by promoting the leakage of the single grain from the leakage hole formed in the frame portion on the lower side in the handle barrel rotation direction in the receiving net. In the self-decomposing combine that holds and transports the stocker side, the single grain that did not leak from the receiving net flows down toward the stocker side of the harvested cereal rice cake with the rotation of the barrel, The generation of small grains, such as being drained out of the machine together with the harvested grains after the threshing process while being mixed into the stock side of the harvested grains, will be suppressed, resulting in the recovery of single grains Efficiency can be improved more effectively.

  In the invention according to claim 2 of the present invention, it is formed so as to be curved along the outer periphery of the handling cylinder that is rotationally driven with the support shaft as a fulcrum, and covers the lower side of the handling cylinder from below. A handling chamber forming member provided on the lower side in the rotation direction of the handling cylinder with respect to the receiving net is allowed to leak the processed material obtained by the threshing process by the rotation of the handling cylinder. A leakage hole is formed.

  According to this characteristic configuration, the processed product obtained by the threshing process by the rotation of the handling cylinder leaks not only from the mesh of the receiving net but also from the leakage hole formed in the handling chamber forming member. Further, it is possible to avoid a decrease in strength of the receiving net that may be caused when a leakage hole is formed in the frame of the receiving net. That is, the leakage area can be increased without enlarging the receiving network and without causing a decrease in the strength of the receiving network, and the leakage of the processed material can be promoted.

  Moreover, since the leakage hole is formed in the handling chamber forming member located on the lower side in the rotation direction of the handling cylinder with respect to the receiving net that is likely to be in a state where the processed material is scraped up and diffused with the rotation of the handling cylinder. As in the case of the invention described in claim 1, since the mass of the processed material is larger than that of cut straw, straw waste, etc., it is easily affected by the centrifugal force due to rotation with the handling cylinder. It is possible to particularly promote the leakage of granulated grains from the leakage hole.

  Therefore, it is possible to secure a large leakage area corresponding to the speeding up of the work without increasing the size of the receiving network and without causing a decrease in the strength of the receiving network. As the amount of processing increases, leakage of single-grained grains can be promoted, and damage due to poor leakage of single-sized grains can be prevented. As a result, recovery of single-sized grains The grain quality can be improved along with the efficiency.

  And by the acceleration | stimulation of the leakage of the single grain from the leakage hole formed in the chamber forming member, as in the case of the invention according to claim 1, the self-decomposing combine is used as a quick grain. Generation | occurrence | production of a grain will be suppressed and, as a result, the collection | recovery efficiency of a single grain can be improved more effectively.

  In the invention according to claim 3 of the present invention, it is formed so as to bend along the outer periphery of the handling cylinder that is rotationally driven with the support shaft as a fulcrum, and covers the lower side of the handling cylinder from below. A receiving net provided, and a frame portion positioned on the lower side in the rotation direction of the handling cylinder in the receiving net; and a handling chamber forming member arranged on the lower side in the rotation direction of the handling cylinder with respect to the receiving net, A leakage hole is formed to allow leakage of a processed product obtained by the threshing process by rotation of the barrel.

  According to this characteristic configuration, the leakage obtained by the threshing process by rotation of the handling cylinder is formed not only from the mesh of the receiving net but also on the frame portion located on the lower side in the rotational direction of the handling cylinder in the receiving net. Leakage also occurs from the holes and the leakage holes formed in the chamber forming member. That is, the leakage area can be increased without increasing the size of the receiving network, and the leakage of the processed material can be more effectively promoted.

  In addition, the treatment hole is not a frame part located on the upper side in the rotation direction of the handling cylinder in the receiving net that tends to be in a state where the treatment object is accumulated, but the treatment object is scraped up and diffused with the rotation of the handling cylinder. Since the frame is located on the lower side in the rotation direction of the handling cylinder in the receiving net that tends to be in a closed state and the chamber forming member located on the lower side in the rotation direction of the handling cylinder with respect to the receiving net, , Especially because it has a large mass compared to sliced straw and straw scraps, it facilitates the leakage of single-grained grains that are easily affected by centrifugal force due to rotation with the barrel, from the leakage hole Can do.

  Therefore, it is possible to secure a larger leakage area corresponding to the speeding up of work without increasing the size of the receiving network. Can be more effectively promoted, and damage caused by poor leakage of single grains can be more reliably prevented. As a result, the recovery efficiency of single grains The quality can be further improved.

  In particular, during the threshing process, the leakage of single grains from the leakage holes formed in the lower part of the frame in the rotation direction of the barrel in the receiving net and the chamber forming member is promoted. In addition, in a self-decomposing combine that holds and conveys the stock side of the harvested cereal by a sandwiching and transporting mechanism, the single-grained grains that have not leaked from the receiving net are separated from the harvested cereal by the rotation of the barrel. It is more effective to suppress the occurrence of small grains that flow down toward the plant side and are discharged to the outside of the machine together with the harvested cereal after threshing while being mixed into the plant side of the harvested cereal. As a result, the recovery efficiency of single grains can be improved more effectively.

  The invention according to claim 4 of the present invention is characterized in that, in the invention according to claim 2 or 3, the chamber forming member is configured to be detachable.

  According to this characteristic configuration, when the handling chamber forming member is worn due to contact with the processed material, the handling chamber forming member can be easily replaced with a new one.

  Therefore, it can be made excellent in maintainability in which the chamber forming member can be easily replaced.
