Problems solved by technology

[0002] The seed coat of the seed has the function of protecting the internal structure of the seed. The seed has a dormant period before germination. If the seed coat is damaged, the internal structure of the seed will lose the protection of the seed coat, and it will be easily damaged or corroded by pathogens, resulting in death and affecting the seed. germination rate
At present, there is no seed selection and damage cleaning equipment. The only way to pick the damaged seeds is to manually identify and sort them with the naked eye. Pick and clean one by one, which is not conducive to precision planting

Embodiment 1

[0025] Embodiment 1: as figure 1 As shown, a kind of seed sorting and wound cleaning equipment includes a seed and metal powder mixing mechanism and an electromagnetic or permanent magnet sorting mechanism. The electromagnetic or permanent magnet sorting mechanism is an electromagnetic drum 7 with a frame 8 positioned above The feed port 6, the finished product seed outlet 9 and the damaged seed outlet 10 located below, the finished product seed outlet 9 and the damaged seed outlet 10 form a certain angle each other, and the finished product seed outlet 9 is located at the side where the seeds pass through first , the damaged seed outlet 10 is located on the side passing behind the seeds. A method for seed selection and damage cleaning, in which seeds and metal powder are fully mixed in the seed and metal powder mixing mechanism, so that the damaged seeds are adhered or infiltrated with metal powder, and then enter the electromagnetic drum 7, and the intact seeds are There i...

Embodiment 2

[0028] Embodiment 2: as figure 1 As shown, the seed and metal powder mixing mechanism is at least one agitator 3, the agitator 3 is an inclined flap type, there is a feed inlet 2 above the agitator 3, and the outlet 16 below the agitator is located Directly above the feed port 6 of the electromagnetic drum 7 . The inclined flap agitator 3 pushes the seeds forward until they fall into the feeding port 6 of the electromagnetic or permanent magnet drum while fully mixing the seeds with the metal powder. All the other are identical with embodiment 1.

[0029] In this embodiment, the mixing mechanism of seeds and metal powder is a stirrer 3, which has been greatly improved on the basis of embodiment 1. The inclined flap type stirrer 3 simulates human hands and completely replaces manual mixing of seeds and metal powder. , effectively reducing the workload and improving the mixing efficiency.

Embodiment 3

[0030] Embodiment 3: as figure 1 As shown, there is a metal powder recovery mechanism between the agitator 3 and the electromagnetic drum 7, the metal powder recovery mechanism is a cylindrical sieve 4, and the cylindrical sieve 4 is placed obliquely toward the electromagnetic drum 7, according to If required, the interior of the cylindrical sieve 4 is set as a multi-layer sieve, each layer of sieve has a discharge port 5, and the cylindrical sieve discharge port 5 is located in front of the electromagnetic or permanent magnet drum feed port 6. Above, there is a collection chamber 13 below the cylinder sieve 4 , and below the collection chamber 13 is a metal powder outlet 12 . All the other are identical with embodiment 2.

[0031] In this embodiment, the cylindrical sieve 4 screens out excess metal powder, and the metal powder screened out can be recycled and reused. While recovering excess metal powder, the problem of a large amount of metal powder adhering to the electr...

Abstract

The invention belongs to the technical field of seed processing. Broken seed cleaning equipment comprises a seed and metal powder mixing mechanism and an electromagnetic separation mechanism, wherein the electromagnetic separation mechanism is provided with a rack, an upper feeding hole, a lower finished seed outlet and a broken seed outlet; A broken seed cleaning method comprises the following steps: I, mixing seeds and metal powder fully by adopting the seed and metal powder mixing mechanism, wherein the metal powder are adhered onto or permeated in the broken seeds, and qualified seeds cannot be adhered or permeated by the metal powder; and II, separating out the broken seeds by the electromagnetic separation mechanism, putting the seeds in the step I in the electromagnetic separation mechanism and separating the broken seeds and the qualified seeds under the action of an electromagnetic field. According to the broken seed cleaning method and equipment, the broken seeds adhered or permeated by the metal powder can be effectively separated out from the qualified seeds, the disadvantages of traditional artificial seed selection are overcome and the precision sowing can be achieved.

Description

technical field [0001] The method and equipment for sorting, breaking and cleaning seeds of the present invention belong to the technical field of seed processing. Background technique [0002] The seed coat of the seed has the function of protecting the internal structure of the seed. The seed has a dormant period before germination. If the seed coat is damaged, the internal structure of the seed will lose the protection of the seed coat, and it will be easily damaged or corroded by pathogens, resulting in death and affecting the seed. germination rate. At present, there is no seed selection and damage cleaning equipment. The only way to pick the damaged seeds is to manually identify and sort them with the naked eye. Picking one by one clean is not conducive to precision sowing. Contents of the invention [0003] The object of the present invention is to propose a method and equipment for seed selection and damage cleaning, so as to realize rapid cleaning of damaged se...
