Description

Technical Field

[0001] The utility model relates to a particle screening machine for seed cultivation, belonging to the technical field of seed processing. Background Art

[0002] Corn seeds are reproductive bodies capable of growing into adult corn plants. They are formed by pollination and fertilization of the ovule. Corn seeds are composed of three parts: the seed coat, the embryo, and the endosperm. Corn seeds are divided into four types: conventional seeds, inbred lines, single-cross seeds, double-cross seeds, and triple-cross seeds. Hybrid corn seeds are the most common seeds used by farmers in the field. The future trend is genetically modified corn seeds. Hybrids produced by crossing two inbred lines are called single-cross seeds. They can be expressed as A×B ("×" represents hybridization). The first generation of single-cross seeds has strong hybrid vigor, which is manifested by strong stress resistance, strong growth, uniformity, and a large increase in yield, generally 20% to 30% higher than naturally pollinated farmer varieties.

A mounting plate 143 is symmetrically installed at the upper front end of the square frame 141. The adjusting shaft 144 is rotatably installed in the middle of the two mounting plates 143. A second electric sliding door 16 is installed on the front side of the coarse screening frame 15, and a third electric sliding door 18 is installed on the front side of the fine screening frame 17. This design solves the problem that the original device has a large exposed space, and a large amount of dust will float out when screening seeds, seriously affecting the health of the staff.

[0022] As the first embodiment of the present utility model: the two first vacuum cleaners 4 are equipped with a dust collection cylinder 6 at their suction ends, and the second vacuum cleaner 7 and the third vacuum cleaner 8 are connected to the rear wall of the box body 1. Through the cooperation of the two first vacuum cleaners 4, the second vacuum cleaner 7 and the third vacuum cleaner 8, it is convenient to clean the dust floating out from the inside of the box body 1 and the inlet of the feed pipe 5, thereby improving the quality of the air around the staff. The screening mechanism 14 is provided with two, and the plurality of second linear motors 140 are respectively installed on the opposite inner sides of the two side panels 13. The coarse screening frame 15 and the fine screening frame 17 are respectively connected to the two adjustment shafts 144, and the coarse screening frame 15 and the fine screening frame 17 are respectively connected to the shaft ends of the two electric push rods 142. Through the cooperation of the electric push rods 142 and the adjustment shafts 144, the coarse screening frame 15 and the fine screening frame 17 can be tilted to facilitate discharging.

[0023] As the second embodiment of the present invention: when in use, first pour the seeds to be screened into the feed pipe 5, and the seeds fall into the coarse screening frame 15, then start the two first vacuum cleaners 4 to clean the dust near the feed pipe 5, and then start the two second linear motors 140 above the box body 1, so that the two second linear motors 140 moving ends can move back and forth quickly for a short distance, thereby driving the coarse screening frame 15 to move back and forth quickly, thereby screening the seeds for the first batch, and the smaller seed particles will fall into the fine screening frame 17, and the larger seed particles will remain in the coarse screening frame 15. The area of ​​the fine screening frame 17 is larger than the coarse screening frame 15, so the smaller seed particles will all fall into the fine screening frame 17, and then start the other two second linear motors 140, The fine screening frame 17 is driven to move back and forth quickly to screen the smaller seed particles again. At this time, fine impurities will fall into the receiving frame 9. During the screening process, the second vacuum cleaner 7 and the third vacuum cleaner 8 are started to clean the dust inside the box 1. After the screening is completed, the sliding door 2 is opened, and the two first linear motors 10 are started to move the fine screening frame 17, the coarse screening frame 15 and the receiving frame 9 to the outside. Then the two electric push rods 142 are started to push the fine screening frame 17 and the coarse screening frame 15. The two adjusting shafts 144 rotate, and the fine screening frame 17 and the coarse screening frame 15 are tilted. Then the third electric sliding door 18 and the second electric sliding door 16 are opened to discharge the seeds. The staff can just take over and open the first electric sliding door 11 to clean the impurities in the receiving frame 9.
