In order to solve the problems that no special test bench is provided for seed bounce tests at present, the existing test methods have difficult control of test conditions, the test data is difficultto acquire, the test site is fixed, the equipment is expensive and the like, the invention discloses a seed bounce test bench which comprises a conveying mechanism, wherein a conveying belt of the conveying mechanism is provided with a soil bin having a soil bin angle adjustment mechanism, and the soil bin generates various angles in a required direction through rotating angle adjustment nuts; andone side of the conveying mechanism is provided with a seed putting mechanism and a liquid spraying mechanism, and the other side of the conveying mechanism is provided with a high-speed video camera. The seed bounce test bench can precisely control factors such as different seed types, different advancing speeds, different seeder rotation speeds, different water spraying amounts, different seedthrowing heights, different water spraying heights, different soil moisture content, different soil particle sizes and different soil bin tilt angles, investigate the influences of the factors on bounce and position variations of seeds, is high in operability and small in size, can be used for test in any suitable place, and is convenient and reliable.
