Description

Stone trap for combine harvesters

The invention relates to one between the intake duct and the concave a combine harvester arranged stone trap, its culden emptying takes place from the front outside.

Such stone trap devices serve to avoid damage the threshing and cleaning assemblies through foreign bodies picked up by the cutting mechanism. They generally consist of a kastenföna-like hollow, which is provided with swiveling bottom or »wall parts, which. can be operated automatically or manually when emptying.

For example, US Pat. No. 3,664 34-8 discloses a stone trap with a bottom flap to be operated from: the driver's cab known by which the sabered material on the underneath located step edge falls. With that the stones become kept away from the threshing drum and concave, however the step ods and the sieves with the foreign bodies continue burdened.

Furthermore, from DT-OS 2 024 706 there is a manual to be emptied Stone collecting device for combine harvesters known whose

takes place after loosening the underneath the bottom area attached quick-release fasteners by swiveling up the flap part up to the stop on the underside of the Sinzugskanales. This creates an opening that is larger than the upper inlet width, so that the foreign bodies cannot become jammed and complete emptying within a very small amount. Time is possible. The connection is made in the closed state of the flap part with the rear wall by means of quick-release fasteners, preferably designed as a rotatable and lockable bolt, which are of can be easily operated by hand at the front.

The invention is explained in more detail below using an exemplary embodiment. In the accompanying drawings show:

Pig. 1: the transition area between the intake duct and the concave with the stone trap in one Sectional view,

Pig. 2: the stone trap after Pig. 1 in detail.

A stone trap 3 is located between the discharge end of the intake channel 1 and the concave 2 of a combine harvester (not shown) arranged, which extends over the entire width of the concave 2. It essentially consists of a whole, a front and bottom area 4; 5 having flap part 6, from a fixed rear wall 7 and from the side walls 8. The flap part 6 is pivotable in the upper area attached to the side walls 8, while the rear wall 7 is rigidly connected to the side walls 8. The connection of the flap part 6 with the rear wall 7 is carried out with several bars 9 distributed over the width of the stone trap 3, the one below the bottom Area 5 arranged brackets 10 are rotatably guided. When the bolt 9 is rotated by 90 °, the one at the front end comes Locking pin 11 located behind the rear wall 7, which is provided with a corresponding recess, to the plant · In cooperation with a rubber seal 12 attached to the angled end of the

Flap part 6 is attached, is a grain-tight and yet Easy-to-solve connection point created. The flap part 6 can be pivoted up to the stop on the resiliently attached apron 13. The pivoted position is shown in broken lines in FIG. 1. On the lower inside of the flap part 6 are several ribs 14 welded in for stiffening. To seal off the flap part 6 from the side walls 8, angle strips are used 15 attached. On the upper side of the side walls 8 are elastic Sealing strip 16 attached. Also the transition between the back wall 7 and the oscillating step floor 17 is through a flexible rubber part 18 covered · The suspension of the stone trap 3 is designed so that it can accommodate all adjustment movements of the concave 2, including the maximum possible lowering can follow. For this purpose 7 hooks 19 are attached to the rear wall, which can be suspended in the continuous capstan 20 of the concave 2. The connection to the machine frame takes place A screw connection 21 on the front side of the side walls 8 which permits a rotary movement.
