Description

  The present invention relates to a combine such as a general purpose combine.

  There is known a combine such as a general-purpose combine that discharges a grain lifted by a grain transport conveyor into a grain tank through a lateral feed spiral cylinder (see, for example, Patent Document 1). The grain tank provided in this type of combiner is normally displaceable to a normal position adjacent to the grain transport conveyor and a maintenance position that rotates around the vertical axis and moves away from the grain transport conveyor. When the grain tank is in the normal position, the laterally-feed spiral cylinder is projected into the grain tank through an opening formed in the grain tank.

JP 2006-288259 A

  By the way, a plate member is provided at the upper end of the grain conveying conveyor so as to surround the laterally-feed spiral cylinder, and when the grain tank is in the normal position, the plate member closes the opening of the grain tank. It has become. However, in this type of combine, due to processing errors and assembly errors, there is a risk that the periphery of the opening of the grain tank and the plate member do not adhere to each other and a gap is generated, and the grain overflows from this gap. .

  Therefore, in the past, the liner was attached to the periphery of the opening of the grain tank or to the plate member so as not to cause the gap, but after the liner was attached in a state where the grain tank was in the maintenance position. Since it is necessary to repeat the work of returning the grain tank to the normal position and checking the gap until the gap disappears, there is a problem that the adjustment work takes time and the assembling workability is lowered.

The present invention has been made in view of the above circumstances and has been created for the purpose of solving these problems. The invention of claim 1 includes a cutting unit for cutting stems at the front of the aircraft, and the aircraft. Between the threshing part and the grain tank disposed on one side of the threshing part for threshing and selecting the grain from the stem, the grain tank disposed on the other side of the machine body A grain conveyor that lifts up and sorts the selected and sorted grain from the threshing unit toward the grain tank, the grain tank adjacent to the grain conveyor To the normal position to rotate around the vertical axis, and to a maintenance position that moves away from the grain conveyor, and the grain conveyor is integrally provided at the upper end thereof. When the grain tank is in the normal position, the grain tank A laterally-feed spiral cylinder that protrudes into the grain tank through an opening formed in the grain, and laterally feeds the grain lifted by the grain conveyor and discharges it into the grain tank; When the grain tank is in a normal position, the plate member that closes the opening, and the position of the plate member with respect to the laterally-feed spiral tube is arranged to laterally feed the lateral-feed spiral tube. A plate member adjusting means that can be adjusted in the direction of the helical axis, wherein the plate member is fixed to a plurality of brackets provided on the side of the grain conveying conveyor via bolts. The plate member adjusting means is a long hole formed in a plurality of the mounting portions or the bracket and extending in the direction of the axial axis of the lateral feed spiral, and the axis of the bolt is at the front. It is combined, characterized in that the plate member by facing the direction orthogonal to the transverse feed helix axis direction is adjustable to the horizontal feed helix axis direction.
The invention according to claim 2 is the combine according to claim 1, wherein the plate member adjusting means makes it possible to adjust the inclination of the plate member with respect to the laterally-feed spiral cylinder.
The invention according to claim 3 is characterized in that the plate member is divided and attached in a state of sandwiching the laterally-feed spiral cylinder from a direction intersecting the laterally-feed spiral axis direction. The combine according to 2.
According to a fourth aspect of the present invention, there is provided a plurality of bolts inserted through a long hole extending in a transverse feed spiral axis direction constituting the plate member adjusting means , wherein the bolt axes are orthogonal to each other. The combine according to any one of claims 1 to 3.

According to the first aspect of the present invention, since the plate member adjusting means for adjusting the position of the plate member that closes the opening of the grain tank in the lateral feed spiral axis direction of the lateral feed spiral cylinder is provided, the gap by the liner is provided. Adjustment is unnecessary, and as a result, the number of rotation operations of the grain tank in the gap adjustment can be reduced and the assembly workability can be improved.
According to the second aspect of the present invention, the plate member adjusting means enables adjustment of the inclination of the plate member with respect to the laterally-feed spiral cylinder, so that the adjustment of the gap including the inclination is facilitated.
According to the invention of claim 3, since the plate member is formed in a divided manner and is attached in a state in which the transverse feed spiral cylinder is sandwiched from the direction intersecting the transverse feed spiral axis direction, the attachment of the plate member is easy. In addition, the degree of freedom in adjusting the position of the plate member can be increased.
Moreover, according to invention of Claim 4, a plate member adjustment means is a long hole long in the transverse feed spiral axial direction formed in the some attaching part or bracket, and is a some hole penetrated by these long holes. Since the bolt shaft cores of the bolts are orthogonal to each other and face the direction orthogonal to the lateral feed spiral axis direction, the tilt adjustment of the plate member with one bolt axis core as a fulcrum and the other orthogonal to the other By adjusting the inclination of the plate member using the bolt shaft core as a fulcrum, it is possible to cope with gap adjustment including various inclinations.
