By comprising in this way, it is made to avoid that the mud scattered from a traveling apparatus with a cover body adheres to a cover body, and it becomes difficult to perform opening / closing operation.

JP 2011-229429 A

  In the combine, the threshing product is stored in the grain tank along with the harvesting work, but, for example, dirt, sand, or other dust adhering to the crop is stored in the grain tank along with the harvesting work. May be mixed. Therefore, in the above-described conventional configuration, a lid that can be opened and closed is provided at the bottom of the Glen tank. By opening the lid while the operation is stopped, impurities accumulated and accumulated in the Glen tank are removed. Can be done.

  When harvesting crops such as rice or wheat where the grains to be harvested are at a high position from the ground, the amount of contaminants as described above is small. In addition, if the crop is harvested by cutting a portion of the pedicle near the ground, the cutting part may come into contact with the ground and soil or sand may enter the glen tank together with the crop. The amount increases. When the amount of contaminants in the Glen tank increases in this way, when the stored threshing processed products are discharged to an external truck or the like, the contaminants are clogged and transported to the discharge conveyor device such as a screw conveyor. The device may be damaged.

  In view of this, it is conceivable to adopt a configuration in which impurities are discharged from the Glen tank while the cutting operation is being performed so that a large amount of impurities are not mixed and accumulated in the Glen tank. However, when configured in this manner, foreign matter discharged from the glen tank may accumulate on the upper surface of the cover body for preventing mud scattering.

  An object of the present invention is to provide a combine that can eliminate problems caused by impurities mixed in a threshing product.

The characteristic configuration of the combine according to the present invention is that a Glen tank that stores threshing products is mounted on a traveling machine body that includes a traveling device,
The traveling machine body is provided with a mudguard cover that prevents mud from scattering from the traveling device in a state located below the Glen tank,
At the bottom of the Glen tank, a discharge part for discharging impurities contained in the threshing product is formed,
The mudguard cover is formed with an opening for dropping and discharging impurities discharged from the discharge portion.

  According to the present invention, since the discharge portion is formed at the bottom of the Glen tank, even if impurities are mixed in the Glen tank due to the cutting operation, the discharge portion is outwardly outward from the Glen tank. Contaminants will fall and be discharged.

  Under the Glen tank, a mudguard cover that prevents mud from scattering from the traveling device is provided, and an opening is formed in the mudguard cover, so that the foreign matter discharged from the discharge part can be removed. It can be dropped and discharged downward through the opening. Since the traveling device exists below the mudguard cover, the fallen foreign matter is discharged onto the ground by the traveling device. In other words, the contaminants are released to the ground and do not remain on the traveling aircraft.

  As a result, even when crops that are likely to contain a lot of contaminants during harvesting are targeted for harvesting, the contaminants do not accumulate in the glen tank. It is possible to avoid problems that damage the device.

  In addition, by providing a mudguard cover, it is possible to avoid the mud from scattering from the traveling device toward the grain tank, but the foreign matter discharged from the grain tank is discharged from the opening, so the upper part of the mudguard cover The problem of depositing on the surface can be avoided.

  Since an opening is formed in the mudguard cover, there is a possibility that mud may scatter from the traveling device toward the Glen tank, but since it is for discharging impurities, the opening may be small, and from the opening The amount of scattering with respect to the Glen tank can be suppressed to a small amount.

  Therefore, it came to be able to provide the combine which can eliminate the malfunction which arises due to the foreign material mixed in the threshing processed material.

  In this invention, it is suitable when the said opening is formed in the state which overlaps with the said discharge part by planar view.

  According to this configuration, since the opening formed in the mudguard cover overlaps with the discharge part formed in the Glen tank in plan view, the contaminants are discharged downward from the Glen tank through the discharge part, It passes through the mudguard cover through the opening and falls down and discharged.

  Therefore, it becomes easy to avoid that the foreign matter discharged from the discharge part falls on the upper surface of the mudguard cover and accumulates there.

  In the present invention, it is preferable that a plurality of the openings are formed.

  According to this configuration, one opening can be made small to allow impurities to fall and discharge while minimizing mud scattering from the traveling device to the grain tank side, and a plurality of openings can be formed. As a result, it is possible to increase the discharge amount of contaminants as a whole, and it is easy to avoid the contaminants remaining in the Glen tank.

  In the present invention, it is preferable that the upper surface of the mudguard cover is formed in an inclined shape that becomes lower as it approaches the opening.

  According to this configuration, when a foreign object falls on the upper surface of the mudguard cover, for example, the foreign object is moved and guided toward the opening along the upper surface formed in an inclined shape along with the vibration of the airframe. Then it is discharged from the opening.

  Therefore, by devising the shape of the mudguard cover, while having the original function of preventing the mud from scattering from the traveling device to the Glen tank side, even if impurities fall on the upper surface of the mudguard cover, It is easy to avoid the accumulation of impurities on the upper surface of the mudguard cover.

  In the present invention, it is preferable that the opening has substantially the same size as the discharge portion.

  According to this configuration, substantially the entire amount of foreign matter discharged downward from the Glen tank through the discharge portion passes through the mudguard cover through the opening and is dropped and discharged downward. In order to drop and discharge almost the entire amount of impurities, the opening may be formed larger than the discharge part, but in this configuration, the opening is substantially the same size as the discharge part, so the opening is larger than necessary. Instead, it is possible to drop and discharge impurities while minimizing the scattering of mud from the traveling device to the Glen tank side.

  In this invention, it is suitable when the said discharge part is comprised with the mesh member which has the mesh which prevents passage of the said threshing processed material, and accept | permits passage of the said foreign material.

  According to this structure, since the threshing processed material stored in the Glen tank cannot pass through the mesh in the discharge unit, it is not dropped and discharged downward. And since the foreign substance mixed in the threshing processed material in a Glen tank can pass the mesh | network in a discharge part, it falls and is discharged | emitted below.

  Therefore, when performing the cutting operation, it is possible to discharge only the foreign matters to the lower outside of the Glen tank while leaving the threshing treatment product in the Glen tank, and to store the threshing treatment product well. Although it is possible, it is possible to accurately avoid the problem that impurities accumulate in the Glen tank.

  In the present invention, it is preferable that a lid that can be switched between a closed state in which the opening is closed and an open state in which the opening is opened is provided.

  According to this configuration, when crops that are likely to contain contaminants in the Glen tank are harvested, the mud from the traveling device to the Glen tank side is removed by switching the lid to the open state. Although there is a possibility of scattering a little, it is possible to avoid accumulation of impurities in the Glen tank. In addition, when cutting a crop with a low risk of contamination, the mud soil can be reliably prevented from traveling from the traveling device to the glen tank by switching the lid to the closed state.

  In the present invention, it is preferable that the lid body is configured to be switchable between the open state and the closed state by swinging around a horizontal axis.

  According to this configuration, since the lid body is swung around the horizontal axis to switch between the open state and the closed state, the lid body is attached to the upper surface of the mudguard cover in both the open state and the closed state. In this case, the lid body is urged downward by its own weight and can maintain a stable posture. That is, the posture can be maintained without providing a special holding mechanism for holding the lid in position.

  In the present invention, it is preferable that the lid body is configured to be switchable between the open state and the closed state by sliding in the horizontal direction.

  According to this configuration, since the lid body is slid in the horizontal direction to switch between the open state and the closed state, the amount of displacement of the lid body in the vertical direction when switching between the open state and the closed state is performed. The lid can be deployed with a small storage space in the vertical direction.
