Description

Technical Field

[0001] This utility model relates to the technical field of corn seed processing equipment, and in particular to a double-selection machine for corn seed processing. Background Technology

[0002] Corn is an annual herbaceous plant belonging to the genus *Zea* of the Poaceae family. Other names include: maize, corn, corn kernels, corn, corn, pearl corn, and large corn kernels. In Northeast China (Liaoning dialect), it is called "pearl grains," in Chaozhou dialect, it is called "coix seed," in Cantonese, it is called "millet," and in Minnan dialect, it is called "foreign wheat." Corn is an annual monoecious, cross-pollinated plant with tall, strong stems. It is an important food and feed crop, and the world's highest-yielding crop, second only to rice and wheat in terms of planting area and total output. Corn has long been hailed as a longevity food, rich in protein, fat, vitamins, trace elements, and fiber, and has great potential for developing highly nutritious and biologically functional foods. After maturity, corn kernels are removed from the cob and become the seeds.

[0003] In existing technologies, the selection process after shelling corn requires screening the kernels to remove shriveled, damaged, and unsuitable seeds, thereby improving the survival rate. Current corn seed screening methods include dual screening, using a combination of a wind-powered screener and a gravity screener. First, the wind separates impurities and some broken seed coats from the corn seeds. Then, the seeds are guided into the gravity screener, where buoyancy separates the shriveled and damaged seeds, causing them to float on the water surface. Finally, a net is used to collect the remaining seeds. Floating defective corn seeds are scooped out. For example, a double-selection machine for corn seed processing, with publication number CN218872490U, involves filling a water tank with water so that the corn seeds fall into the water after passing through an air sieve. The buoyancy of the water causes the shriveled and broken seeds to float on the surface. Then, by turning the handle, the turntable rotates, which in turn drives the rotating shaft and the scooping net to rotate. The scooping net scoops out the floating seeds and throws them into the waste trough in the collection box, thus performing a secondary screening of the seeds and greatly improving the seed survival rate.

[0004] However, when the double-selection machine for corn seed processing uses a net to scoop out defective products floating on the water surface, the defective corn seeds tend to stick to the surface of the net because they are wet, and cannot be completely poured out. As the net is put back into the water, the defective corn seeds and other impurities will still float on the surface, resulting in poor cleaning effect.

[0005] Therefore, it is necessary to provide a double-selection machine for corn seed processing to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides a double-selection machine for corn seed processing, which solves the problem that when a double-selection machine for corn seed processing uses a net to scoop out defective products floating on the water surface, the defective corn seeds are easily stuck to the surface of the net because they are wet, and cannot be completely poured out. As the net is put back into the water, the defective corn seeds and other impurities will still float on the surface, resulting in poor cleaning effect.

[0009] A collection device is fixedly installed on the top of the threaded block and the slider. The collection device includes a collection box, a collection groove and a drain hole. The collection box is fixedly installed on the top of the threaded block and the slider. The collection groove is opened in the middle of one side of the collection box, and the drain hole is opened on both sides of the outer surface of the collection box.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] First Embodiment

[0029] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 This is a schematic diagram of the structure of a first embodiment of a compound selection machine for corn seed processing provided by this utility model; Figure 2 for Figure 1 The diagram shows the structural design of the gravity screening machine housing. Figure 3 for Figure 2 The diagram shown is a side view of the gravity screening machine casing. Figure 4 for Figure 3 The enlarged schematic diagram at point A is shown below; Figure 5 for Figure 4 The diagram shows the structure of the collection device.

[0030] A double-selection machine for corn seed processing includes: a wind-powered screening machine 1 and a gravity screening machine housing 2;

[0031] Placement slot 3 is located on one side of the outer surface of the gravity screening machine housing 2. A water tank 6 is slidably installed inside the placement slot 3. A water trough 7 is opened in the middle of the top of the water tank 6. A driving component 8 is fixedly installed on one side of the outer surface of the water tank 6. A threaded rod 9 is fixedly connected to the end of the output shaft of the driving component 8 through a coupling. A limiting rod 12 is fixedly installed on one side inside the water trough 7. A threaded block 10 is threadedly engaged on the outer surface of the threaded rod 9. A slider 11 is slidably installed on the outer surface of the limiting rod 12.

[0032] A collection device 13 is fixedly installed on the top of the threaded block 10 and the slider 11. The collection device 13 includes a collection box 131, a collection groove 132, and a drain hole 133. The collection box 131 is fixedly installed on the top of the threaded block 10 and the slider 11. The collection groove 132 is opened in the middle of one side of the collection box 131. The drain hole 133 is opened on both sides of the outer surface of the collection box 131.

[0033] Feed hopper 4 is fixedly installed on one side of the top of the gravity screening machine housing 2. Liquid inlet pipe 5 is fixedly installed in the middle of the top of the gravity screening machine 2. Liquid outlet pipe 19 is fixedly installed at the bottom of one side of the outer surface of the water tank 6.

[0034] Both the threaded block 10 and the slider 11 are made of iron, and the collection box 131 is set with a magnetic structure.

[0035] The threaded block 10 has a threaded hole in the middle of its surface, which is threaded to the outer surface of the threaded rod 9. The slider 11 has a sliding hole in the middle of one side, which is slidably installed on the outer surface of the limiting rod 12.

[0036] Pull rods 14 are fixedly installed on both sides of the outer surface of the water tank 6.

[0037] The drive component 8 adopts a servo motor structure.

[0038] When the output shaft of the drive unit 8 rotates forward and backward, it drives the threaded rod 9 to rotate forward and backward. The meshing threaded block 10 slides back and forth in the water tank 7. When not in operation, the collection box 131 moves to the rightmost side inside the water tank 7. The collection trough 132 is opened in the middle of the left side of the collection box 131. As the threaded rod 9 rotates, the collection box 131 slides to the left to retrieve the broken corn seeds floating on the water surface. As the collection box 131 moves to the leftmost side inside the water tank 7, the collection trough 132 fits against the surface of the water tank 7, so that the corn seeds will not fall out.

[0039] When the collection box 131 is placed on top of the threaded block 10, the collection box 131 is attracted to the top of the threaded block 10. The strong magnetic attraction effect can be overcome by a person pulling hard.

[0040] Both the casing 2 and the water tank 6 of the gravity separator can be made of transparent plastic material, making it easy to observe the internal water level.

[0041] The other end of the inlet pipe 5 is connected to a water source and a water pump to control the water inlet, and the other end of the outlet pipe 19 is connected to a drainage ditch and a water pump to control the drainage.

[0042] The existing device of the wind-powered screening machine uses wind power to blow out impurities from the corn seeds being fed, while the corn seeds continue to fall downwards under gravity into the feed hopper 4 and then into the water tank 6 inside the gravity screening machine housing 2.

[0043] The threaded block 10 is attached to the surface of the inner wall of the water tank 7, and the slider 11 is attached to the other side of the inner wall of the water tank 7.

[0044] The working principle of the compound selection machine for corn seed processing provided by this utility model is as follows:

[0045] During operation, the collection box 131 is first installed on top of the threaded block 10 and the slider 11. The magnetic force of the collection box 131 is attracted to the top of the threaded block 10 and the slider 11. Hold the pull rod 14 to place the water tank 6 into the placement slot 3.

[0046] The corn seeds screened by the wind-powered screening machine 1 are guided into the water tank 7 through the feed hopper 4, and the water source is injected into the water tank 7 through the liquid inlet pipe 5. The water level is matched with the height of the collection tank 132.

[0047] After a period of settling, the defective corn seeds float on the water surface. The output shaft of the drive unit 8 rotates, causing the threaded rod 9 to rotate. The threaded rod 9 rotates and engages with the threaded block 10. The threaded block 10 slides on the inner wall surface of the water tank 7 and causes the collection box 131 and the slider 11 to slide on the surface of the limiting rod 12. This causes the collection box 131 to slide from right to left inside the water tank 7. The collection trough 132 collects the defective corn seeds floating on the water surface. As the collection box 131 continues to slide to the left and adheres to the left side of the inner wall of the water tank 7, the collection trough 132 completely collects the floating defective corn seeds.

[0048] Then the drain pipe 19 drains the water in the water tank 7. The filter screen at the end of the drain pipe 19 filters the intact corn seeds, allowing the water to drain out. As the water level drops, the water in the collection tank 132 is collected back into the water tank 7 through the drain hole 133 and drained away. All that remains in the collection tank 132 are defective corn seeds.

[0049] After the water is drained, the user holds the lever 14 to pull the water tank 6 out of the placement slot 3, pulls the collection box 131 upward from the surface of the threaded block 10 and the slider 11, and pours out the defective corn seeds collected in the collection slot 132.

[0050] The intact corn seeds in water tank 6 are collected separately.

[0051] Compared with related technologies, the compound selection machine for corn seed processing provided by this utility model has the following beneficial effects:

[0052] This utility model provides a double-selection machine for corn seed processing. It collects corn seeds after air sieving via a water tank 7, while simultaneously injecting water into the tank 7 to match the height of the collection trough 132. The output shaft of the drive unit 8 controls the rotation of the threaded rod 9. The rotation of the threaded rod 9 engages with the threaded block 10, causing the collection box 131 to move on the water surface. The collection trough 132 scoops up and collects substandard corn seeds floating on the water surface. Water is then drained through the drain pipe 19, leaving the substandard corn seeds collected inside the collection trough 132. The collection box 131 can then be removed from the surface of the threaded block 10. This device has a simple structure, strong practicality, and conveniently collects substandard corn seeds floating on the water surface. It allows users to easily clean the substandard corn seeds collected in the collection box 131, improving the scooping and collection effect of the selection machine and enhancing the practicality of the device.

[0057] The number of rotating shafts (16) can be set according to requirements.

[0058] The working principle of the compound selection machine for corn seed processing provided by this utility model is as follows:

[0059] During operation, the threaded block 10 rotates alternately in both directions with the threaded rod 9. The threaded block 10 drives the connecting plate 15, rotating shaft 16, rotating column 17 and stirring plate 18 to move back and forth inside the water tank 7, stirring the corn seeds in the water tank 7.

[0060] Furthermore, as the water flow squeezes the mixing plate 18, the mixing plate 18 drives the rotating column 17 to rotate, thus enhancing the mixing effect on the corn seeds.

[0061] Compared with related technologies, the compound selection machine for corn seed processing provided by this utility model has the following beneficial effects:

[0062] This utility model provides a double-selection machine for corn seed processing. By installing a connecting plate 15 between the threaded block 10 and the slider 11, and setting multiple rotating columns 17 and stirring plates 18 at the bottom of the connecting plate 15, as the threaded block 10 moves, the rotating columns 17 and stirring plates 18 move in the water tank 7, stirring the corn seeds in the water tank 7, so that the defective corn seeds that are pressed at the bottom can float upwards, and the traction force of the water flow pushes the rotating columns 17 and stirring plates 18 to rotate, enhancing the stirring effect on the corn seeds and improving the screening effect of defective products in the corn seeds.
