Description

Technical Field

[0001] This utility model relates to the field of seed breeding device technology, and more specifically, it relates to a cotton drought-resistant and salt-alkali tolerant variety breeding device. Background Technology

[0002] Treating cotton seeds before sowing is an important technical measure to ensure that cotton seedlings are strong and healthy, and even achieve high yield and quality. Among these measures, seed selection is of paramount importance. Seed sorting machines are usually used to sort cotton seeds to obtain mature and plump seeds.

[0003] 1. In cotton seed screening, seeds are typically poured manually into the screening machine's feed inlet. However, manual operation makes it difficult to precisely and consistently control the total amount of seeds fed in and the rate of descent per unit time. This unstable feeding condition easily leads to momentary overload or underload of the screening machine, preventing the screen from fully utilizing its sorting efficiency. Ultimately, this results in uneven cotton seed screening, low efficiency, and a significant deterioration in the overall screening effect.

[0004] 2. During the delinting and subsequent processing of cotton seeds, a large amount of fine dust, broken fiber fragments, and incompletely separated seed coats and other light impurities are often mixed in. During the sieving process, these impurities, due to their similar physical properties to high-quality seeds or their tendency to be trapped, are difficult to remove effectively and completely. This results in the so-called "high-quality seeds" obtained after sieving still containing a considerable proportion of impurities, severely contaminating seed purity and greatly reducing the actual sieving effect and seed quality.

[0005] 3. When using the traditional gravity-feed method, the large amount of cotton seeds accumulated in the silo creates continuous and significant vertical pressure on the narrow discharge port at the bottom. This high pressure easily causes the seeds to clump or agglomerate at the discharge port, resulting in intermittent or continuous discharge blockages and poor flow. Frequent blockages not only interrupt the continuous screening process but also require manual intervention to clear them, severely slowing down the overall operation and significantly reducing the screening efficiency of cotton seeds.

[0006] Therefore, there is an urgent need for a breeding device for drought-resistant and salt-tolerant cotton varieties. Utility Model Content

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, this utility model provides a breeding device for drought-resistant and salt-tolerant cotton varieties, which has the following beneficial effects:

[0020] 1. This utility model achieves linearly adjustable opening of the feed inlet through the linkage design of the sliding plate and the baffle. Combined with the constant amplitude of the vibrating screen, it ensures that the flow rate and speed of seeds falling onto the screen plate are uniform and controllable per unit time. This avoids the problems of manual feeding overload or intermittent feeding, and greatly improves the efficiency of screen sorting and the yield of good seeds.

[0021] 2. This invention utilizes the combined action of a blower's negative pressure suction and a vibrating screen. External airflow penetrates the support mesh to form a continuous upward air separation, precisely removing lightweight impurities such as dust and broken shells at the moment the seeds jump and separate. These impurities are then collected in a collection box via air ducts for centralized processing, significantly reducing the impurity rate of superior seeds and ensuring the purity of subsequent breeding.

[0022] 3. This utility model precisely controls the opening and closing gap of the sliding plate through an electric push rod, combined with the impact of the wedge block and the overall vibration of the hopper, achieving a dual effect to break up seed blockage. This effectively eliminates the jamming problem of traditional gravity-feeding and maintains smooth and stable discharge. Attached Figure Description

[0034] Please see Figure 3 and Figure 4 The impurity removal structure includes a support net 11, which is fixedly connected to the through hole of the hopper 6. A ventilation opening is provided on the right side of the lower part of the hopper 6. A fixed cover 12 is fixedly connected to the ventilation opening of the hopper 6, and a fan 13 is fixedly connected to the fixed cover 12. The support net 11 and the lower left side of the hopper 6 have the same tilt angle.

[0035] Please see Figure 5 and Figure 6 The impact structure includes equally spaced fixed plates 14, which are fixedly connected to the hopper 6. The fixed plates 14 are splinedly connected to splined rods 15. A counterweight 16 is fixedly connected to the lower end of the splined rod 15, and a wedge block 17 is fixedly connected to the upper end of the splined rod 15. A connecting plate 18 is fixedly connected to the splined rod 15, and a spring 19 is fixedly connected between the connecting plate 18 and the adjacent fixed plate 14. The elastic force of the spring 19 is equal to the weight of the counterweight 16.

[0036] Working principle: Cotton seeds are placed into the hopper 6, and then the vibrator 5 is started. The vibrator 5 drives the vibrating screen body 3 to move up and down reciprocally. Then, the two electric push rods 9 are started, and the electric push rods 9 drive the sliding plate 8 to move to the right. The sliding plate 8 slides along the inclined plate 7, and a gap is created between the sliding plate 8 and the hopper 6. The seeds roll down through the gap. The baffle 10 always blocks the through holes on the front and back sides of the hopper 6. The seeds roll down onto the support net 11. The vibrating screen body 3 drives the hopper 6 to vibrate up and down. When the seeds fall onto the support net 11, the support net 11 will impact the seeds upward, causing the seeds to separate from the support net 11 briefly. Under the action of gravity, the seeds will fall back onto the support net 11 and finally be discharged from the bottom of the hopper 6. The discharged seeds roll onto the screen plate 4 for seed selection.

[0037] Before using this device, connect the blower 13 to the impurity collection box via a flexible air guide tube. After starting the blower 13, the blower 13 draws air from the bottom of the hopper 6. The air enters the impurity collection box along the flexible air guide tube and filters the impurities in the air.

[0038] When the seeds fall onto the support net 11, the blower 13 operates to draw air from the lower part of the hopper 6. Outside air enters the lower part of the hopper 6 through the support net 11 and enters the impurity collection box through the air guide pipe. During the above process, the flowing air cleans the impurities carried in the seeds, improving the cleanliness of the seeds.

[0039] Furthermore, as the hopper 6 moves up and down with the vibrating screen body 3, the counterweight 16 drives the wedge block 17 to move up and down repeatedly through the spline rod 15. The spring 19 is compressed repeatedly. Under the action of the counterweight 16, the inclined block moves up and down repeatedly to impact the inclined plate 7, thereby causing the inclined plate 7 to vibrate, reducing the probability of seeds getting stuck in the hopper 6 and improving the smoothness of seed feeding.

For all the fixed connections mentioned above, welding is preferred.
