Seed impact test device and damage resistance testing method

Abstract

The invention belongs to the technical field of seed activity detection and relates to a seed crash testing device and a damage-resisting capability detection method. The device comprises a crashing barrel (2), a blade (4), a projecting disc (5), a connection disc (8), a motor (6), a base (7) and a control device, wherein an upper cover (1) is arranged at the top of the crashing barrel (2); the connection disc (8) is fixedly connected with the motor (6); the projecting disc (5) and the blade (4) are arranged in the connection disc (8); a power output shaft of the motor (6) penetrates through the centers of the projecting disc (5) and the blade (4) so that the projecting disc (5) and the blade (4) rotate along the rotation of the power output shaft; and the crashing barrel (2) sleeves the outer side of the connection disc (8). The seed crash testing device provided by the invention is simple in structure and uniform in seed stress; the seed crash testing device can cause different mechanical losses aiming at different crop seeds and the seeds are not crushed; and with the adoption of contrastive analysis before and after the seeds are damaged, and different damage degrees, the system reflects the damage-resisting capability of the detected seeds.

Description

technical field [0001] The invention belongs to the technical field of seed vitality detection, and relates to a seed collision test device and a damage resistance detection method. Background technique [0002] Corn seeds are a very important means of production. With the continuous improvement of the market and farmers' requirements for seed quality, it is necessary to carry out refined management of corn seeds in the entire field production and factory processing, so as to protect the vitality of corn seeds to the greatest extent. After the corn seeds are physiologically mature and harvested, the key to quality protection and control lies in the processing link. After the grain is mature, mechanical damage is prone to occur in all links of the whole process of mechanized harvesting, loading and unloading, drying, threshing, cleaning, storage and sales. [0003] At present, a large number of studies focus on the damage of drying temperature to corn kernels, and the impact...

Problems solved by technology

Although some researchers have measured the degree of seed breakage sensitivity by measuring the grain breakage sensitivity, the seeds have been broken after the breakage sensitivity test, and the germination test cannot be carried out, which cannot directly reflect the change of seed vigor after damage. There are also researchers who reflect the damage of seeds by measuring the rate of grain stress cracks. This method mainly relies on subjective judgment when measuring the rate of cracks, and only reflects the degree of damage of seeds from the physical level, and cannot establish an effective relationship with seed vitality.
