Abstract

A seed cart includes first and second mating frames. The hopper is mounted on the first frame for holding seed and has an outlet to discharge the seed. A conveyor is mounted on the second frame for movement between seed loading and unloading positions. A plurality of cylinders with extendible and retractable arms control the desired position of the conveyor. A plurality of load cells are mounted on the second frame and support the first frame. The weigh scales weigh the first frame, the hopper, and the seed in the hopper, without weighing the conveyor. Therefore, an accurate amount of seed can be dispensed from the hopper via the conveyor. Wheels and a hitch tongue can be detachably mounted on the second frame to convert the cart from a stationary unit to a mobile unit.

Claims

1. A seed cart for transporting seed to a field, comprising:

a first frame having opposite side and opposite ends to form a horizontal base;

a second frame beneath the first frame and having opposite sides and opposite ends;

a hopper integrally fixed to the first frame for receiving and holding seed, and having sloped walls converging to a seed outlet for discharge of seed by gravity flow from the hopper;

a conveyor mounted on the second frame for transporting and having an inlet beneath the hopper outlet to receive seed from the hopper;

weigh scales between the first frame and the second frame and supporting the first frame so as to weigh the hopper without weighing the conveyor; and

a cylinder having a lower end pivotally connected to the second frame and a telescoping arm pivotally connected to the conveyor to control movement of the conveyor between loading and unloading positions relative to the hopper.

2. The seed cart of claim 1 wherein at least one axle with wheels is removably mounted to the second frame.

3. The seed cart of claim 2 further comprising a hitch tongue removably mounted to the second frame.

4. The seed cart of claim 1 further comprising the weigh scale includes a load bar mounted at each corner of the second frame.

5. The seed cart of claim 1 wherein the hopper is free from internal seed mixing mechanisms.
