Description

Technical Field

[0001] This utility model relates to the field of seed drying technology, and in particular to an agricultural seed drying device. Background Technology

[0002] Newly harvested seeds have a high moisture content and are prone to mold. Therefore, they must be dried promptly to ensure their stability during storage. Traditional methods of seed drying include ventilation and sun drying. While these methods are simple, energy-saving, economical, and safe, they are susceptible to limitations imposed by weather and site conditions and are labor-intensive.

[0003] Therefore, some seed drying equipment has appeared on the market. However, hot air is usually introduced on one side of the drying drum, which makes the drying of seeds uneven and affects the drying effect. In addition, the hot exhaust gas generated during seed drying is usually discharged directly, resulting in a waste of heat and energy. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an agricultural seed drying device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An agricultural seed drying device, comprising:

[0007] Machine tool;

[0008] A drying cylinder is vertically installed through the machine base and fixedly connected to the machine base. A rotating tube is installed through the top of the drying cylinder and is rotatably connected to the drying cylinder. A hollow stirring rod is installed inside the rotating tube inside the drying cylinder. An air outlet is provided on the lower side wall of the hollow stirring rod.

[0009] A rotating mechanism is located at the top of the drying cylinder, and the rotating mechanism is connected to the rotating tube and is used to drive the rotating tube to rotate;

[0010] A hot air mechanism is located at the upper end of the machine platform and is connected to the upper end of the rotating pipe.

[0011] As a further improvement of this utility model, the rotating mechanism includes a motor fixedly installed on the top of the drying cylinder, the output shaft of the motor is fixedly connected to a first gear, and a second gear is fixedly sleeved on the side wall of the rotating tube, the second gear meshing with the first gear.

[0012] As a further improvement of this utility model, the hot air mechanism includes a housing fixedly installed on the upper part of the machine platform and a hot air blower. The housing is provided with a second connecting pipe inside. Both ends of the second connecting pipe penetrate the inner wall of the housing and extend to the outside of the housing. The second connecting pipe is fixedly connected to the housing. A plurality of heat-conducting plates are fixedly sleeved on the side wall of the second connecting pipe located inside the housing. One end of the second connecting pipe is connected to the output end of the hot air blower. The other end of the second connecting pipe is connected to a first connecting pipe. The end of the first connecting pipe away from the second connecting pipe is connected to the upper end of a rotating pipe through a rotating vent joint. The upper end of the housing is connected to an air outlet pipe. The end of the air outlet pipe away from the housing is connected to the top of the drying cylinder. The lower end of the housing is connected to a discharge pipe. The discharge pipe penetrates the machine platform and extends downward.

[0013] As a further improvement of this utility model, an electric discharge valve is installed at the bottom of the drying cylinder, and two temperature and humidity sensors are fixedly embedded on the side wall of the drying cylinder, with the two temperature and humidity sensors arranged one above the other.

[0014] As a further improvement of this utility model, a feed hopper is provided at the top of the drying cylinder.

[0015] As a further improvement of this utility model, the upper end of the machine base is provided with a controller, and the lower end of the machine base is fixedly connected with four support legs at the four corners.

[0016] The beneficial effects of this utility model are:

[0017] The hot air mechanism pumps hot air into the rotating tube via a hot air blower. The hot air is then evenly distributed to the seeds inside the drying cylinder through the air outlet on the hollow stirring rod, drying the seeds. At the same time, the hot exhaust gas discharged from the drying cylinder is guided into the shell through the air outlet pipe. The heat in the hot exhaust gas is then transferred to the air in the second connecting pipe through the heat conduction plate. This allows for the recovery and utilization of the heat in the hot exhaust gas generated during seed drying, achieving energy-saving effects.

[0018] The rotating mechanism drives the rotating tube to rotate, which in turn drives the hollow stirring rod to rotate, stirring the seeds inside the drying cylinder. This allows the seeds to be dried while being stirred, effectively improving the uniformity and efficiency of seed drying.

[0019] This invention enables seeds to be dried while being stirred, effectively improving the uniformity and efficiency of seed drying. It also allows for the recovery and utilization of heat from the hot exhaust gas generated during seed drying, thus achieving energy-saving effects. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-3 An agricultural seed drying device, comprising:

[0026] The machine base 1 has a controller 16 at its upper end and support legs 2 fixedly connected to the four corners at its lower end. A drying cylinder 3 is vertically mounted on and fixedly connected to the machine base 1. A feed hopper 10 is located at the top of the drying cylinder 3, with a hinged, closable cover plate. The cover plate is closed during seed drying. An electric discharge valve 5 is installed at the bottom of the drying cylinder 3. Two temperature and humidity sensors 4 are fixedly embedded in the side wall of the drying cylinder 3, positioned vertically to monitor the temperature and humidity of the seeds. A rotating tube 18, rotatably connected to the top of the drying cylinder 3, is installed through the top of the drying cylinder 3. A hollow stirring rod 20 is located inside the rotating tube 18 within the drying cylinder 3, and an air outlet is located on the lower side wall of the hollow stirring rod 20. A rotating mechanism is located at the top of the drying cylinder 3, connected to the rotating tube 18, and used to drive the rotating tube 18 to rotate. A hot air mechanism is located at the upper end of the machine base 1 and connected to the upper end of the rotating tube 18.

[0027] Temperature and humidity sensor 4, electric discharge valve 5, motor 6, and hot air blower 15 are all electrically connected to controller 16.

[0028] In this utility model, the rotating mechanism includes a motor 6 fixedly installed on the top of the drying cylinder 3, a first gear 7 fixedly connected to the output shaft of the motor 6, and a second gear 8 fixedly sleeved on the side wall of the rotating tube 18, the second gear 8 meshing with the first gear 7.

[0029] The hot air mechanism includes a housing 14 fixedly mounted on the upper part of the machine base 1 and a hot air blower 15. A second connecting pipe 13 is provided inside the housing 14. Both ends of the second connecting pipe 13 penetrate the inner wall of the housing 14 and extend to the outside of the housing 14. The second connecting pipe 13 is fixedly connected to the housing 14. Multiple heat-conducting plates 19 are fixedly sleeved on the side wall of the second connecting pipe 13 located inside the housing 14. One end of the second connecting pipe 13 is connected to the output end of the hot air blower 15, and the other end of the second connecting pipe 13 is connected to a first connecting pipe 11. The end of the first connecting pipe 11 away from the second connecting pipe 13 is connected to a rotating vent joint 9. The upper end of 8 is connected to a rotary vent joint 9, which allows the rotating pipe 18 to rotate without affecting the introduction of hot air into the rotating pipe 18. The first connecting pipe 11, the second connecting pipe 13, the vent pipe 12, and the exposed side wall of the shell 14 are all insulated, such as with insulation cotton, to avoid energy waste caused by heat loss. The upper end of the shell 14 is connected to the vent pipe 12, and the end of the vent pipe 12 away from the shell 14 is connected to the top of the drying cylinder 3. The lower end of the shell 14 is connected to the discharge pipe 17, which passes through the machine base 1 and extends downward. The discharge pipe 17 is designed to be relatively long so that the discharged exhaust gas is far away from the equipment.

[0030] In use, seeds are added to the drying cylinder 3 through the feeding hopper 10. The hot air blower 15 is started, pumping hot air into the rotating tube 18 through the first connecting pipe 11 and the second connecting pipe 13. The hot air is then evenly distributed to the seeds inside the drying cylinder 3 through the air outlet on the hollow stirring rod 20, drying the seeds. Then, the motor 6 is started, driving the first gear 7 to rotate. Since the first gear 7 meshes with the second gear 8, it drives the rotating tube 18 to rotate, which in turn drives the hollow stirring rod. Rotating the cylinder 20 stirs the seeds inside the drying cylinder 3, enabling simultaneous stirring and drying. Simultaneously, the exhaust pipe 12 guides the hot exhaust gas from the drying cylinder 3 into the shell 14, and the heat from the exhaust gas is transferred to the air in the second connecting pipe 13 via the heat-conducting plate 19. This allows for the recovery and utilization of the heat from the exhaust gas generated during seed drying. The exhaust gas is then discharged through the discharge pipe 17. After drying is complete, the equipment is stopped, and the electric discharge valve 5 is activated to discharge the dried seeds.
