Description

Technical Field

[0001] The invention belongs to the technical field of forestry planting, and in particular relates to a Yunnan pine seed drying device with a screening function. Background Art

[0002] The seeds of Yunnan pine grow in its cones, which mature in two years. From mid-to-late March to early April each year, the ovoid male cones developed at the base of the tender branches of adult Yunnan pine trees, their microsporangiums mature, the pollen sacs split open, and a large amount of pollen is scattered. When the megasporangium begins to appear, it is yellow-green or purple-red, oblong, and fertilized by male pollen. After a short period of development, it forms a cone-shaped young fruit, which no longer increases in size that year. In late March of the following year, as the temperature rises, the fertilized young fruit develops rapidly and expands continuously. By December, the color of the cones changes from the original light green or purple-red to brown or dark green, indicating that the fruit is ripe. The fruit cones are processed by spreading the collected Yunnan pine cones on a cement floor or a brick-paved drying yard. After several days of exposure, the fruit scales quickly crack and the seeds fall out.

[0003] After the seeds are collected, they need to be dried to improve their storage resistance. When the existing device is used to dry the seeds, it is impossible to remove the impurities and defective products contained in the seeds, resulting in a low survival rate of the dried seeds when they are planted. Secondly, when the existing equipment is used to dry the seeds, the seeds cannot be classified. Seeds of different qualities are mixed together. Directly planting low-quality seeds is difficult to survive, resulting in a lower survival rate. In addition, the efficiency of drying seeds in the existing method is low, and a large number of seeds cannot be dried quickly. Summary of the invention

[0004] The object of the present invention is to provide a Yunnan pine seed drying device with a screening function to solve the problems raised in the above-mentioned background technology.

[0006] Preferably, the driving mechanism includes a driving motor and a mounting column, a transmission shaft is provided on the left side of the output shaft of the driving motor, a driving gear 1 and a connecting gear are fixedly installed in the middle of the transmission shaft, an indirect gear is meshed at the rear of the connecting gear, a transmission gear is meshed at the rear of the indirect gear, a transmission rod is fixedly connected to the middle of the transmission gear, a driving gear 2 is fixedly connected to the left end of the transmission rod, and an mounting cavity is opened inside the mounting column.

[0007] Preferably, the screening mechanism includes a plurality of conical shells, a plurality of sieve holes are opened on the curved surface of the conical shells, a rotating ring is fixedly installed at the connection between two adjacent conical shells, a spiral plate is fixedly connected to the inside of the plurality of conical shells, a large gear is fixedly connected to the middle part of the leftmost conical shell, a small gear is fixedly connected to the middle part of the rightmost conical shell, and a C-shaped plate is fixedly connected to the right side of the rightmost conical shell.

[0008] Preferably, the driving motor and the lower surface of the mounting column are fixedly connected to the base, the transmission shaft, the indirect gear, and the transmission rod are rotatably connected to the mounting column, the connecting gear, the indirect gear, and the transmission gear are all located inside the mounting cavity, and the left end of the transmission rod is rotatably connected to the connecting plate.

[0009] Preferably, the diameters of the multiple conical shells gradually increase from right to left, the apertures of the multiple sieve holes gradually increase from right to left, the large gear is meshed with drive gear 2, the small gear is meshed with drive gear 1, the rightmost conical shell is rotatably connected to the right support plate, and the leftmost conical shell is rotatably connected to the left support plate.

[0010] Preferably, the left end of the fixed shell is fixedly connected to the connecting plate, the rotating wheels are in contact with the rotating ring, the fixed shell is adapted to the middle part of the spiral plate, the hemispherical shell is fixedly connected to the right support plate, the baffle is rotatably connected to the rightmost conical shell, the tooth ratio of the large gear and the small gear is equal to the tooth ratio of the driving gear two and the driving gear one, and the air outlet is located on the front and rear sides of the microwave dryer.

[0011] The beneficial effects of the present invention are as follows:

[0012] 1. The present invention drives multiple cone shells to rotate through a driving mechanism. Since the diameters of the multiple cone shells gradually increase from right to left, the Yunnan pine seeds entering will move to the left. However, due to the obstruction of the spiral plate, the seeds move slowly to the left. The microwave dryer emits microwaves to dry the seeds directly below the microwave dryer. At the same time, the hot air for drying enters the interior of the fixed shell through a connecting pipe and is finally discharged from the air outlet to assist in drying the seeds inside the cone shell, thereby first screening out smaller impurities and dust in the Yunnan pine seeds, and then screening out shriveled and incomplete seeds, thereby solving the problem that the impurities and defective products contained in the seeds cannot be removed during the existing seed drying, resulting in a low survival rate of the dried seeds when planted.

[0013] 2. The present invention works by driving a motor to drive the transmission shaft to rotate. The rotation of the transmission shaft causes the driving gear 1 and the connecting gear to rotate. The rotation of the connecting gear drives the transmission gear to rotate through the indirect gear. The transmission gear drives the driving gear 2 to rotate through the transmission rod. The angular velocity of the transmission driving gear 1 and the driving gear 2 is the same, so that multiple cone shells and C-shaped plates are driven to rotate, and the Yunnan pine seeds that need to be dried are continuously poured into the interior of the hemispherical shell through the feed port. When the notch of the rotating C-shaped plate coincides with the notch of the fixed baffle, the Yunnan pine seeds will enter the space between the cone shell and the fixed shell, thereby realizing efficient intermittent feeding to prevent blockage and ensure the drying effect.

[0014] 3. As the seeds move to the left, the frequency of flipping will increase, thereby further ensuring that the seeds are dried more evenly. When the dried seeds move to the leftmost cone shell area, seeds smaller than the leftmost sieve holes will be screened out, and seeds larger than the leftmost sieve holes will eventually be discharged from the left side of the cone shell, thereby completing the screening and classification of seeds during the drying process, thereby solving the problem that the existing equipment cannot classify the seeds when drying seeds, which causes seeds of different qualities to be mixed together and the survival rate cannot be guaranteed when planted.

At the same time, the hot air for drying enters the interior of the fixed shell 8 through the connecting pipe 5, and is finally discharged from the air outlet 11 to assist in drying the seeds inside the cone shell 131, so as to first screen out the smaller impurities and dust in the Yunnan pine seeds, and then screen out the shriveled and incomplete seeds, thereby solving the problem that the impurities and defective products contained in the seeds cannot be removed during the existing seed drying, resulting in a low survival rate of the dried seeds when planted.

[0025] Working principle:

[0026] Before using the present invention, hot air for drying is connected to the connecting pipe 5;

[0027] When the present invention is used, the driving motor 121 works, driving the transmission shaft 122 to rotate, the transmission shaft 122 rotates to rotate the driving gear 1 123 and the connecting gear 124, the connecting gear 124 rotates and drives the transmission gear 126 to rotate through the indirect gear 125, the transmission gear 126 drives the driving gear 2 128 to rotate through the transmission rod 127, the angular speeds of the driving gear 1 123 and the driving gear 2 128 are the same, because the gear ratio of the large gear 135 and the small gear 136 is equal to the gear ratio of the driving gear 2 128 and the driving gear 1 123, the multiple cone shells 131 are driven to rotate, the rotating wheel 18 is in contact with the rotating ring 133, and the multiple cone shells 131 are supported, the C-shaped plate 137, the spiral plate 134, and the rotating ring 133 are driven to rotate by the cone shell 131, and the rotating ring 133 will drive the rotating wheel 18 to rotate;

[0028] The Yunnan pine seeds to be dried are continuously poured into the interior of the hemispherical shell 4 through the feed port 3. When the notch of the rotating C-shaped plate 137 coincides with the notch of the fixed baffle 7, the Yunnan pine seeds will enter the space between the cone shell 131 and the fixed shell 8, thereby realizing intermittent feeding to prevent blockage and ensure the drying effect. Since the diameters of the multiple cone shells 131 gradually increase from right to left, the entering Yunnan pine seeds will move to the left, but due to the obstruction of the spiral plate 134, the Yunnan pine seeds can only move slowly to the left. Due to the rotation of the cone shell 131, the smaller impurities and dust of the Yunnan pine seeds are first screened out, and then the shriveled and incomplete seeds are screened out. During the whole process, the microwave dryer 10 works to emit microwaves to dry the seeds directly below the microwave dryer 10. The seeds are dried, and the hot air for drying enters the interior of the fixed shell 8 through the connecting pipe 5, and is finally discharged from the air outlet 11, which assists in drying the seeds inside the cone shell 131. At the same time, the hot air will accelerate the rapid discharge of materials smaller than the sieve holes 132. During the movement of the seeds to the left, the frequency of flipping will be accelerated, thereby further ensuring more uniform drying. When the dried seeds move to the area of ​​the leftmost cone shell 131, the seeds smaller than the leftmost sieve holes 132 will be screened out, and the seeds larger than the leftmost sieve holes 132 will eventually be discharged from the left side of the cone shell 131, thereby completing the screening and classification of seeds during the drying process, and improving the survival rate of seed planting in the later stage. During the whole process, the materials passing through the sieve holes 132 will be collected in the collection shell 19 directly below.
