〔Constitution〕
On the side wall plate of the tank body, a lid support portion that protrudes outward from the tank body at the side edge of the side wall opening of the tank body and is continuous over the entire length of the side wall opening is provided, and at the end of the lid plate for the side wall opening Connecting means for protruding toward the surface of the lid plate and being continuous over the entire length of the lid plate, and closing and locking the lid plate by tightening and connecting the mounting portion to the lid support portion. Some combine grain tanks.
[0007]
[Action]
When the mounting portion of the lid plate is tightened and connected to the lid support portion of the tank main body by the connecting means, the lid plate is closed and locked, so that a grain tank can be configured. In this state, the lid supporting portion of the tank body and the mounting portion of the lid plate are connected to each other to form a rib state, and the tank is reinforced near the side wall opening.
[0008]
〔effect〕
Therefore, a strong tank which is easy to manufacture due to the side wall opening and reinforced near the side wall opening is obtained. For that reason, the lid supporting portion and the attaching portion for locking the lid plate are used as reinforcing means, so that it can be obtained inexpensively from the viewpoint of part production and assembly.
[0009]
The configuration, operation and effect of the invention according to claim 2 are as follows.
[0010]
〔Constitution〕
In the structure of the invention according to claim 1, the lid support portion is constituted by a side wall plate rising portion which is bent from the main body of the side wall plate toward the outside of the tank main body, and the mounting portion is formed by a lid plate. Of the cover plate is bent from the main body toward the surface of the cover plate.
[0011]
[Action]
Since the lid supporting portion is constituted by the side wall plate standing portion and the mounting portion is constituted by the lid standing portion, the lid supporting portion of the tank body can be manufactured at once with the side wall plate by molding the side wall plate. Can be formed at once with the lid plate by molding the lid plate.
[0012]
〔effect〕
A tank reinforced near the side wall opening can be obtained at low cost not only from the side where the lid support part and the mounting part for locking the lid plate are used as reinforcing means, but also from the side of manufacturing the lid support part and the mounting part. Can be

An upper lid supporting portion 12c that stands up toward the outer side of the main body and protrudes outward from the tank main body at the upper edge of the side wall opening 16 is provided on the lower end side of the upper divided side wall plate 12a. By bending and forming the upper end of the plate constituting the lower divided side wall plate 12a, the main body of the lower divided wall plate 12a rises toward the outside of the tank body, and the side wall opening 1 is formed. A lower lid supporting portion 12c protruding outward from the tank body at a lower edge portion is provided on an upper end side of the lower divided side wall plate 12a, and a front lid supporting portion 13a is provided at an end of the front side wall plate 13; A rear lid supporting portion 14a is provided at an end of the rear side wall plate 14, and the upper mounting portion 17b of the lid plate 17 is attached to the upper mounting portion 17b and the upper lid supporting portion 12c at a plurality of locations in the lateral direction of the lid plate. The connection screw 18 configured as described above, and a connection configured to be mounted over the lower mounting portion 17b and the lower lid support portion 12c at a plurality of locations of the lower mounting portion 17b of the lid plate 17 in the lateral direction of the lid plate. Screw 18, connecting screw 19 configured to be attached to cover plate body 17 a and front cover support portion 13 a at a plurality of positions in the cover plate longitudinal direction at the front end side of cover plate body 17 a, rear end side of cover plate body 17 a At several locations in the vertical direction It is constituted by providing a connecting screw 19 which is configured to be worn over the cover plate body 17a and the rear cover support portion 14a.
[0019]
Both the upper mounting portion 17b and the lower mounting portion 17b of the cover plate 17 are formed so as to continuously project from the cover plate body 17a to the cover plate surface side over the entire length of the cover plate 17 in the lateral direction. . Both the upper lid support portion 12c and the lower lid support portion 12c of the side wall plate 12 continuously project from the divided side wall plate 12a to the outside of the tank main body over the entire length of the side wall opening 16 in the tank main body lateral direction. It is formed in a state.
[0020]
That is, the front and rear ends of the cover plate main body 17a are fastened and connected to the cover support portions 13a and 14a of the front and rear side wall plates 13 and 14 by the connection screws 19, and the upper and lower mounting portions 12b of the cover plate 17 are moved upward. The cover plate 17 is attached to the tank body 10a by closing the side wall opening 16 by tightening and connecting to the lid supporting portion 12c of the divided side wall plate 12a and the lower divided side wall plate 12a with the connecting screw 18, and It is designed to be locked in this closed state. In the closed and locked state of the cover plate 17, the upper cover support portion 12c of the tank body 10a and the upper mounting portion 17b of the cover plate 17 are connected to each other to reinforce the grain tank 10 near the upper side of the side wall opening 16. The lower lid support portion 12c of the tank body 10a and the lower mounting portion 17b of the lid plate 17 are connected to each other to form a rib state that reinforces the grain tank 10 near the lower side of the side wall opening 16.
[0021]
As shown in FIG. 3, a lever guide 20 is provided on the outer side of the front side wall plate 13 of the grain tank 10. The lever guide 20 is configured to guide the operation of the vibrator lever 21 by the guide groove 20a, and is arranged along the lateral width direction of the front side wall plate 13 so as to be a reinforcing member of the grain tank 10. Connected. The vibrator lever 21 vibrates a covering member (not shown) provided so as to cover the upper part of the bottom screw 6 in the bottom of the grain tank 10, and the grain stays in the tank. To promote the emission of water.
[0022]
As shown in FIG. 1, a bag used for taking out grains into a paddy bag is provided at a lower portion of the side wall 11 of the pair of side wall plates 11, 12 of the grain tank 10 which is located outside the body. A support rod 22 and a grain take-out port 23 that can be freely opened and closed are provided. As shown in FIG. 3, a window 24 having a transparent plate is provided above the front side wall plate 13 of the grain tank 10 so that the inside of the tank can be seen from the outside.
[0023]
As shown in FIG. 5 (a), the conveying cylinder 8a of the vertical screw conveyor 8 has a small inner diameter for the inner diameter of the discharge port 7a of the gear case 7 fixed to the bottom of the grain tank 10. It is. In other words, as shown in FIG. 5B, instead of the vertical screw conveyor 28 having a large transfer capacity provided with a transfer cylinder 28a having a large inner diameter corresponding to the gear case 7, a vertical screw having a transfer capacity smaller than the vertical screw conveyor 28 is used. A conveyor 8 is mounted. Then, instead of the bottom screw 26 as shown in FIG. 5B used when a vertical screw conveyor 28 having a large conveying capacity is mounted, the bottom screw having a feed pitch smaller than the feed pitch of the bottom screw 26 is used. By equipping the screw 6, the gear case 7 is shared with the vertical screw conveyor 28 having a large conveying capacity and the vertical screw conveyor 8 having a small conveying capacity. The transport capacity is adjusted so that the transport capacity of the vertical screw conveyor 8 matches the transport capacity of the vertical screw conveyor 8.
