Abstract
Abstract The invention relates to a crop store and to a mechanism for loading same. The crop store may have a movable wall and pressure indicating means. Also more than one compartment can be included in the crop store. The loading mechanism is compressing means, preferably a rotatable screw conveyor or a reciprocating piston, which communicates with the crop store via a supply channel.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
116 words
A crop store comprising at least one container, a longitudinal supply channel for receiving crop being connected to said store, said channel having substantially straight walls along its longitudinal sides and an outlet in communication with the interior of said container, compressing means, including a compressing member that reciprocates in said supply channel and cooperates with at least part of a wall of said channel so that crop in said channel is forced under pressure through said outlet into said container, a discharging device being positioned in said store for discharging crop through an exit in a wall of said container, said exit having an opening which forms a part of the wall of said container.
Claim 2
Dependent Claim
116 words
A crop store comprising at least one container, a longitudinal supply channel for receiving crop being connected to said store, said channel having substantially straight walls along its longitudinal sides and an outlet in communication with the interior of said container, compressing means, including a compressing member that reciprocates in said supply channel and cooperates with at least part of a wall of said channel so that crop in said channel is forced under pressure through said outlet into said container, a discharging device being positioned in said store for discharging crop through an exit in a wall of said container, said exit having an opening which forms a part of the wall of said container.
