Description

Technical Field

[0001] The utility model belongs to the technical field of crop seed production, in particular to a drying device for crop seeds. Background Art

[0002] The main function of seed drying is to reduce the moisture content of seeds to meet the requirements of safe storage, while maintaining the vigorous germination and vitality of seeds. Through drying, the moisture in the seeds is forced to drop below the safe moisture content, which helps to reduce the occurrence of mildew and ensure the quality grade and germination rate of seeds. The metabolism rate of dried seeds is slow, and they can maintain excellent seed quality and vitality for a long time. In addition, drying also helps to promote the after-ripening of seeds.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 4 A drying device for crop seeds includes a frame device for supporting and retracting and dumping crop seeds, and a box-barrel device installed on the frame device for holding the crop seeds for drying. The box-barrel device is provided with an air circulation device for spraying hot air to promote the flow and drying of the crop seeds.

[0024] In this embodiment: the frame device includes a base 101, two support frames 102 are symmetrically arranged on one side of the base 101, two electric push rods 103 are symmetrically arranged on one side of the support frame 102, and a connecting seat 104 is installed at the telescopic end of the electric push rod 103, and a bracket 105 is rotatably installed between the connecting seats 104. The bracket 105 and the box cylinder 201 are slidably connected, and the base 101 supports the electric push rod 103 to extend, and pushes the bracket 105 to rise through the connecting seat 104, lifting one end of the box cylinder 201, and at the same time, the other end of the box cylinder 201 rotates under the support of the support frame 102 and the rotating shaft 202;

[0025] In this embodiment: the box-barrel device includes a box-barrel body 201, which is cylindrical, and a feed pipe 203 is arranged on the box-barrel body 201. The feed pipe 203 is arranged in the middle of the box-barrel body 201 and is welded to the box-barrel body 201. A first sealing cover 204 is installed on the feed pipe 203, and a second sealing cover 205 is installed at one end of the box-barrel body 201. The second sealing cover 205 is threadedly connected to the box-barrel body 201. Two rotating shafts 202 are symmetrically arranged near the second sealing cover 205 of the box-barrel body 201. The rotating shaft 202 is connected to the support frame 102 by bearings. The crop seeds are poured into the box-barrel body 201 from the feed pipe 203, and the first sealing cover 204 is tightened to close it. The second sealing cover 205 is opened, and the box-barrel body 201 rotates under the support of the support frame 102 and the rotating shaft 202 to pour out the crop seeds.

[0026] In this embodiment: the air circulation device includes a booster pump 301, and three air equalizing pipes 303 are evenly distributed above the booster pump 301. The three air equalizing pipes 303 are arranged horizontally in the lower half of the box cylinder 201 along the radial direction of the box cylinder 201, and a number of air nozzles 304 are evenly distributed on the air equalizing pipe 303. A heating box 302 is arranged on one side of the booster pump 301, and a filter head 305 is arranged above the heating box 302. The filter head 305 is installed in the upper half of the box cylinder 201 and is sealed with threaded connections. The filter head 305, the heating box 302, the booster pump 301 and the air equalizing pipe 303 are connected in sequence by pipelines. The booster pump 301 draws the heated air in the heating box 302 and transports it into the air equalizing pipe 303, and sprays it out from the air nozzle 304, which promotes the crop seeds to rotate and flow in the box cylinder 201. At the same time, the hot air accelerates the drying of the crop seeds, and the exhaust gas is filtered by the filter head 305 and sucked back into the heating box 302 for recycling.

[0027] Working principle: pour the crop seeds from the feed pipe 203 into the box cylinder 201, and tighten the first sealing cover 204 to seal it. The booster pump 301 draws the heated air in the heating box 302 and transports it into the air equalizing pipe 303, and sprays it out from the air nozzle 304, pushing the crop seeds to rotate and flow in the box cylinder 201. At the same time, the hot air accelerates the drying of the crop seeds. The exhaust gas is filtered by the filter head 305 and sucked back into the heating box 302 for recycling. After drying, open the second sealing cover 205, and the base 101 supports the electric push rod 103 to extend, and pushes the bracket 105 up through the connecting seat 104, lifting one end of the box cylinder 201. At the same time, the other end of the box cylinder 201 rotates under the support of the support frame 102 and the rotating shaft 202 to pour out the crop seeds.
