Description

Technical Field

[0001] This utility model relates to the field of corn seed storage technology, and in particular to a corn seed storage device. Background Technology Corn seeds are scientifically selected and processed propagation materials. Their core value lies in carrying complete genetic material and being able to develop into a new generation of plants. Corn seeds are generally harvested in autumn, but sowing time is mostly in the following spring, so storage equipment is needed to store corn seeds.

[0002] According to the search, the Chinese patent "A corn seed storage device" authorized announcement number "CN221128007U" uses a hot air blower, a round pipe, a drying pipe located on the inner wall of the storage box, a movable shaft and a flipping plate to turn the corn seeds in the storage box, so that the corn seeds accumulated at the bottom can breathe through the air.

[0003] However, in the aforementioned application, the hot air sprayed by the drying pipe located on the inner wall of the storage box mostly flows near the inner wall of the storage box, which causes the corn seeds close to the inner wall of the storage box to dry quickly, while the corn seeds located at the center of the storage box dry more slowly. This can easily lead to uneven drying of the corn seeds in the storage box, thereby affecting the storage effect of the corn seeds. Utility Model Content

[0004] Therefore, it is necessary to provide a corn seed storage device to address the problem of uneven drying of corn seeds in the storage box.

[0005] The device includes: a storage cylinder, a servo motor fixedly connected to the top of the storage cylinder, and an electric heating wire fixedly connected to the inner wall of the storage cylinder; and a control mechanism, which includes a movable shaft rotatably connected to the top wall of the storage cylinder, the top of the movable shaft penetrating the storage cylinder and fixedly connected to the output shaft of the servo motor, a spiral blade and a guide plate fixedly connected to the surface of the movable shaft, a limit cylinder fixedly connected to the lower end of the inner wall of the storage cylinder, the surface of the spiral blade located on the inner wall of the limit cylinder, and several feeding blocks fixedly connected to the surface of the guide plate.

[0006] In one embodiment, a dispersing rod is fixedly connected to the upper surface of the movable shaft, and a pushing block is fixedly connected to the lower surface of the movable shaft.

[0007] In one embodiment, a mounting rod is fixedly connected to the upper surface of the movable shaft.

[0008] In one embodiment, a rotating shaft is rotatably connected to the surface of the mounting rod, and annularly distributed arc-shaped blocks are fixedly connected to the surface of the rotating shaft. The interaction between the rotating shaft and the arc-shaped blocks allows for the movement of the corn seeds within the storage cylinder, thereby enhancing the fluidity of the seeds and ensuring uniform drying.

[0009] In one embodiment, the surface of the storage cylinder is provided with a first heat insulation plate and a second heat insulation plate, with the surface of the second heat insulation plate snapped onto the inner wall of the first heat insulation plate. The cooperation between the first and second heat insulation plates effectively protects the surface of the storage cylinder, reducing the time it takes for heat to dissipate and ensuring the drying effect on the corn seeds inside.

[0010] In one embodiment, the surfaces of both the first and second heat insulation boards are curved into an arc shape, and both the first and second heat insulation boards are polyurethane foam components.

[0011] In one embodiment, a magnetic block is slidably connected to the inner wall of the second heat insulation plate, and the surface of the magnetic block is engaged with the inner wall of the first heat insulation plate.

[0012] In one embodiment, a magnetic plate is embedded in the surface of the first heat insulation plate, and the surface of the magnetic block is slidably connected to the inner wall of the magnetic plate. Beneficial effects

[0013] 1. By cooperating with the movable shaft, guide plate and feeding block, the corn seeds located on the inner wall of the storage cylinder are moved to the center of the storage cylinder, thereby improving the flow of corn seeds in the storage cylinder and avoiding the situation where corn seeds located on the inner wall of the storage cylinder dry faster and corn seeds located at the center of the inner wall of the storage cylinder dry slower. By cooperating with the movable shaft, limiting cylinder and spiral blades, the corn seeds on the bottom wall of the storage cylinder are transported to the top, thereby realizing the replacement of corn seeds in different layers in the storage cylinder and ensuring uniform drying of corn seeds in the storage cylinder. 2. The corn seeds conveyed upward by the spiral blades are dispersed by the dispersing rod, thereby improving the fluidity of the corn seeds in the storage cylinder. The pushing block scrapes the corn seeds on the bottom wall of the storage cylinder to the area below the spiral blades, thus facilitating the upward conveying of the corn seeds on the bottom wall of the storage cylinder by the spiral blades.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The following is combined Figures 1-5 This invention describes a corn seed storage device.

[0019] In one embodiment, a corn seed storage device includes: a storage cylinder 100, a servo motor 200 fixedly connected to the top of the storage cylinder 100, and an electric heating wire 300 fixedly connected to the inner wall of the storage cylinder 100; and a control mechanism 400, which includes a movable shaft 401 rotatably connected to the inner top wall of the storage cylinder 100, the top of the movable shaft 401 penetrating the storage cylinder 100 and fixedly connected to the output shaft of the servo motor 200, a spiral blade 404 and a guide plate 402 fixedly connected to the surface of the movable shaft 401, a limiting cylinder 405 fixedly connected to the lower end of the inner wall of the storage cylinder 100, the surface of the spiral blade 404 located on the inner wall of the limiting cylinder 405, and a plurality of feeding blocks 403 fixedly connected to the surface of the guide plate 402.

[0020] It should be noted that both the guide plate 402 and the feeding block 403 have rounded corners. The surface of the guide plate 402 is V-shaped, and the surface of the feeding block 403 is curved into an arc shape. The guide plate 402, the feeding block 403, and the spiral blade 404 are all made of ultra-high molecular weight polyethylene, which has good self-lubricating properties. Because the surfaces of the guide plate 402, the feeding block 403, and the spiral blade 404 have extremely low coefficients of friction, the friction between them and the corn seeds is small during rotation, reducing the damage caused by rotating and pushing the corn seeds.

[0021] The guide plate 402, feeding block 403 and spiral blade 404 have strong impact resistance and can withstand a certain impact force without breaking or being damaged. During the rotation, they push the corn seeds in the storage cylinder 100 without breaking.

[0022] The guide plate 402, feeding block 403, and spiral blade 404 have excellent corrosion resistance: they can resist the erosion of some chemicals that may exist in the corn storage environment.

[0023] It should be noted that: the storage cylinder 100 includes a storage tank and a storage cover. The storage pipe and the storage cover are installed by bolts and nuts. The upper surface of the movable shaft 401 is rotatably connected to the inner wall of the storage cover. The top of the storage cover is connected to the feed pipe, the air inlet pipe and the air outlet pipe. The surface of the feed pipe is covered with a round cover. The surface of the air outlet pipe is embedded with a one-way valve. The one-way valve is used to prevent external gas from entering the storage tank through the air outlet pipe. The bottom of the storage cover is equipped with a humidity sensor and a temperature sensor. The lower surface of the storage tank is embedded with a solenoid valve. The air inlet pipe is threadedly connected to the air delivery pipe on the air delivery pump.

[0024] In this embodiment, when corn seeds need to be stored, a feeding device such as an auger feeder is used to transport the corn seeds into the storage cylinder 100. Once a certain amount, such as two-thirds of the internal capacity of the storage cylinder 100, is transported, the auger feeder stops transporting corn seeds into the storage cylinder 100 and the feed pipe on the storage cylinder 100 is sealed. When the humidity sensor detects that the humidity of the corn seeds inside the storage cylinder 100 exceeds the set threshold, the monitoring system will issue a warning signal and automatically turn on the servo motor 200 and the electric heating wire 300.

[0025] When the electric heating wire 300 is energized, it heats the inner wall of the storage cylinder 100. The output shaft of the servo motor 200 rotates, driving the movable shaft 401 to rotate. The rotating movable shaft 401 drives the spiral blades 404 to rotate and the guide plate 402 and the feeding block 403 to move in a ring. The rotating spiral blades 404 spirally convey the corn seeds on the bottom wall of the storage cylinder 100 upwards. The ring-moving guide plate 402 and the feeding block 403 guide the corn seeds on the inner wall of the storage cylinder 100 to the vicinity of the center of the storage cylinder 100, thereby increasing the fluidity of the corn seeds in the storage cylinder 100 and drying the corn seeds evenly.

[0026] The humidity sensor monitors the humidity of the corn seeds in the storage cylinder 100. When the humidity reaches the corresponding threshold, the temperature sensor monitors the temperature inside the storage cylinder 100. When the temperature is too high, the monitoring system will issue a warning signal and automatically turn off the electric heating wire 300 and automatically turn on the air pump. The air pump draws in fresh air from the outside and delivers it into the storage cylinder 100 through the air inlet pipe. The rotating movable shaft 401, guide plate 402, feeding block 403 and spiral blade 404 move the corn seeds. When too much fresh air enters the storage cylinder 100, the air inside the storage cylinder 100 is discharged through the air outlet pipe and one-way valve, so that the stored corn seeds can reach a suitable temperature and humidity environment. At this time, the monitoring information is transmitted to the monitoring system, which automatically turns off the air pump and servo motor 200.

[0027] like Figure 5 As shown, a dispersing rod 414 is fixedly connected to the upper surface of the movable shaft 401, a pusher block 413 is fixedly connected to the lower surface of the movable shaft 401, two mounting rods 406 are fixedly connected to the surface of the movable shaft 401, a rotating shaft 412 is rotatably connected to the surface of the mounting rods 406, and annularly distributed arc-shaped blocks 407 are fixedly connected to the surface of the rotating shaft 412.

[0028] In this embodiment, the rotating shaft 401 drives the mounting rod 406, rotating shaft 412, arc block 407, and dispersing rod 414 to move in a ring. The arc block 407, which moves in a ring, comes into contact with the corn seeds. Under the action of force, the arc block 407 is pushed, thereby increasing the fluidity of the corn seeds. The limiting cylinder 405 is used to limit the spiral blade 404 in the feeding process, ensuring that the spiral blade 404 can stably transport the corn seeds upward. The dispersing rod 414, which moves in a ring, is used to disperse the corn seeds that are being transported upward.

[0029] like Figure 2-3 As shown, the surface of the storage cylinder 100 is provided with a first heat insulation plate 408 and a second heat insulation plate 409. The surface of the second heat insulation plate 409 is snapped onto the inner wall of the first heat insulation plate 408. The surfaces of both the first heat insulation plate 408 and the second heat insulation plate 409 are curved into an arc shape. Both the first heat insulation plate 408 and the second heat insulation plate 409 are polyurethane foam components. A magnetic block 410 is slidably connected to the inner wall of the second heat insulation plate 409. The surface of the magnetic block 410 is snapped onto the inner wall of the first heat insulation plate 408. A magnetic plate 411 is embedded in the surface of the first heat insulation plate 408. The surface of the magnetic block 410 is slidably connected to the inner wall of the magnetic plate 411.

[0030] A PLC controller is installed on the surface of the first heat insulation plate 408 to control the working status of the electric heating wire 300, servo motor 200, temperature sensor and humidity sensor.

[0031] The first insulation board 408 and the second insulation board 409 of the polyurethane foam component have excellent heat insulation effect, good corrosion resistance and chemical stability, and can be used for a long time under the environmental conditions of corn seed storage.

[0032] In this embodiment, the first heat insulation plate 408 and the second heat insulation plate 409 are pressed against the storage cylinder 100, so that the second heat insulation plate 409 is stuck on the first heat insulation plate 408. The magnetic block 410 is pushed to move inside the first heat insulation plate 408 and the second heat insulation plate 409 and is attracted to the magnetic plate 411, so that the first heat insulation plate 408 and the second heat insulation plate 409 are initially positioned. At this time, an electric wrench is used to thread the screws onto the first heat insulation plate 408 and the second heat insulation plate 409, thereby making the first heat insulation plate 408 and the second heat insulation plate 409 tightly installed, so that the first heat insulation plate 408 and the second heat insulation plate 409 are stably installed on the surface of the storage cylinder 100.

[0033] Working principle: The output shaft of the servo motor 200 rotates, driving the movable shaft 401 to rotate. The rotating movable shaft 401 drives the spiral blades 404 to rotate, and the guide plate 402, feeding block 403, mounting rod 406, rotating shaft 412, arc block 407, and dispersing rod 414 to move in a ring. The rotating spiral blades 404 spirally convey the corn seeds on the bottom wall of the storage cylinder 100 upward. The ring-moving dispersing rod 414 is used to disperse the conveyed corn seeds. The ring-moving guide plate 402 and feeding block 403 guide the corn seeds on the inner wall of the storage cylinder 100 to the vicinity of the center of the storage cylinder 100. The ring-moving arc block 407 contacts the corn seeds. Under the action of force, the arc block 407 is pushed, which enhances the fluidity of the corn seeds in the storage cylinder 100, thereby drying the corn seeds evenly.

[0034] It should be noted that the storage cylinder 100, servo motor 200, electric heating wire 300, movable shaft 401, first heat insulation plate 408, second heat insulation plate 409, magnetic block 410, and magnetic plate 411 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the servo motor 200 and electric heating wire 300 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
