Description

Technical Field

[0001] The utility model belongs to the technical field of seed sorting, and in particular relates to a rapeseed seed sorting device. Background Art

[0002] Rapeseed is one of the main oil crops and nectar crops, with an oil content of up to 37.5%-46.3%. It is widely cultivated in China. When people sow rapeseed seeds, they need to screen the rapeseed seeds to remove necrotic seeds (i.e., seeds with imperfect grains). The rapeseed seed screening method in the prior art usually adopts a manual sorting method, such as screening out imperfect grains in the seeds through a hand-cranked mesh screen. Although this method can classify seeds with full grains suitable for planting, it is also easy for imperfect grains to mix into normal seeds. At the same time, this method also has the problems of high labor intensity, time and labor consumption, and low work efficiency.

[0003] In the long-term rapeseed planting practice, people found that imperfect seeds in rapeseed seeds will float on the water surface, while seeds with full grains and suitable for planting will sink to the bottom of the water.

[0004] Therefore, a rapeseed seed sorting device is proposed. Utility Model Content

[0005] The utility model provides a rapeseed seed sorting device, aiming to solve the problems of high labor intensity, time-consuming and labor-intensive screening and low work efficiency in the existing rapeseed seed screening.

[0007] A rapeseed seed sorting device also includes a cover plate and a water injection pipe fixed to the top of the sorting box by bolts, the cover plate is located on one side of the water injection pipe; a temporary storage box fixed to the bottom of the sorting box near one side of the motor by bolts; and a stop valve fixed to the bottom of the temporary storage box by bolts.

[0008] Preferably, a filtering hole is provided on one side outer wall of the second semi-ring cover, and the heights of the tops of the second semi-ring cover and the first semi-ring cover are both lower than the height of the top of the sorting box.

[0009] Preferably, the rotating rod is a hollow structure, and the internal space of the rotating rod is communicated with the feeding chute.

[0010] Preferably, the outer side wall of the scraper matches and fits with the inner side walls of the first half annular cover and the second half annular cover.

A water injection pipe 13 is fixedly connected to the top of the sorting box 1 near the cover plate 8 by bolts, and one end of the water injection pipe 13 is inserted into the interior of the sorting box 1. A temporary storage box 14 is fixedly connected to the bottom of the sorting box 1 near the motor 5 by bolts. The sorting box 1 and the temporary storage box 14 are connected, and a stop valve 15 is fixedly connected to the bottom of the temporary storage box 14 by bolts.

[0025] It should be noted that, since most of the existing rapeseed seed sorting adopts manual sorting, it is easy for imperfect seeds to be mixed with normal seeds, and there are also problems of high labor intensity, time-consuming and labor-intensive, and low work efficiency. In this embodiment, the rapeseed seeds are transported to the middle of the space formed by the first half ring cover 2 and the second half ring cover 3 through the feed chute 9. Good rapeseed seeds will sink to the bottom, and necrotic rapeseed seeds will float on the water surface. By rotating the stirring rod 10 and the scraper 11, the unsorted rapeseed seeds can be broken up, thereby facilitating the separation of good and bad seeds from top to bottom. The good rapeseed seeds can also be swept into the temporary storage box 14 for collection, and the bad rapeseed seeds are discharged through the discharge port 12 by water flow. The rapeseed seed sorting can be in progress all the time without stopping the operation, thereby improving the sorting efficiency.

[0026] Specifically, in this embodiment, when the present solution is used, the rapeseed seeds are poured into the upper material cover 7, the motor 5 drives the rotating rod 6 to rotate slowly through its output end, the upper material cover 7 on the rotating rod 6 rotates synchronously, and the rapeseed seeds in the upper material cover 7 flow through the lower material trough 9 to the middle of the space formed by the first half ring cover 2 and the second half ring cover 3. Since good rapeseed seeds will sink to the bottom and necrotic rapeseed seeds will float on the water surface, as the rotating rod 6 rotates, the stirring rod 10 and the scraper 11 on the rotating rod 6 rotate synchronously, and the stirring rod 10 stirs the first half ring cover 2 and the second half ring cover 3. The rapeseed seeds in the annular cover 3 are scattered, so that good seeds are separated from bad seeds. The good rapeseed seeds sink to one side of the scraper 11, and the scraper 11 sweeps the sinking seeds to the top of the temporary storage box 14. The good rapeseed seeds fall into the interior of the temporary storage box 14. When the stop valve 15 is opened, the good rapeseed seeds will be discharged through the stop valve 15, and the external water source is injected into the sorting box 1 through the water injection pipe 13, and the water level is always higher than the discharge port 12. The necrotic rapeseed seeds floating on the water surface are discharged through the discharge port 12, thereby realizing the sorting of good and bad seeds.

[0027] In a further preferred embodiment of the present invention, Figure 2 As shown, a filtering hole is opened on one side outer wall of the second semi-ring cover 3, and the heights of the tops of the second semi-ring cover 3 and the first semi-ring cover 2 are both lower than the height of the top of the sorting box 1.

[0028] In this embodiment, a space for the necrotic seeds floating on the water surface to flow and move can be provided, so that the necrotic seeds can leave the space surrounded by the second half ring cover 3 and the first half ring cover 2, thereby facilitating the necrotic seeds to be discharged from the sorting box 1.

[0029] In a further preferred embodiment of the present invention, Figure 6 As shown, the rotating rod 6 is a hollow structure, and the inner space of the rotating rod 6 is connected to the feeding chute 9.

[0030] In this embodiment, the rapeseed seeds in the upper material cover 7 can enter the rotating rod 6 and flow from the lower material trough 9 to the middle of the space formed by the first half ring cover 2 and the second half ring cover 3, and under the stirring of the stirring rod 10, better separation of good seeds and necrotic seeds in the rapeseed can be achieved.
