Description

Technical Field

[0001] This utility model belongs to the field of grain storage technology, and in particular relates to a sealed and waterproof structure for grain storage equipment. Background Technology

[0002] Grains refer to the general term for various plant seeds used in cooking, and can also be broadly referred to as "cereals". Grain crops are rich in nutrients, mainly protein, vitamins, dietary fiber, fat, starch, etc. After grain processing, grains need to be stored, which requires grain storage equipment. Grain storage equipment is a key facility to ensure the safe storage of grains, prevent loss, and maintain quality.

[0003] Existing grain storage equipment has poor sealing and waterproofing performance, making it difficult to ensure that the storage environment is not affected by rain or humidity. When the humidity of the grain storage environment is too high, the grain is prone to absorbing moisture from the air and becoming moldy. Moldy grain not only has a decline in quality and nutritional value, but may even produce toxic substances, posing a threat to human health. Utility Model Content

[0004] The purpose of this invention is to provide a sealed and waterproof structure for grain storage equipment. By setting a sealing plate, specifically, the spring force on the outer surface of the support rod causes the slip ring to descend, allowing it to slide downwards on the outer surface of the support rod, thus moving the two connecting rods away from each other. Then, the slider at the bottom of the connecting rod slides inside the groove, causing the side of the slider away from the support rod to contact the inner wall of the storage bin, completing the sealing of the storage bin. The spring ensures that the sealing plate is in close contact with the feed inlet to prevent rainwater from seeping in. This solves the problem that existing grain storage equipment has poor sealing and waterproof performance, which easily leads to grain becoming damp and moldy, posing a threat to human health.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model discloses a sealed and waterproof structure for grain storage equipment, including a storage bin and a feed inlet. The bottom of the feed inlet is fixedly connected to the top of the storage bin. A sealing plate is inserted into the top of the feed inlet. The outer surface of the sealing plate contacts a bin cover. A support rod is fixedly connected to the bottom of the sealing plate. A slip ring is slidably connected to the outer surface of the support rod. A pull rod is fixedly connected to the top of the slip ring. A handle is fixedly connected to the top of the pull rod. The top of the pull rod passes through the sealing plate and extends to the outside. The outer surface of the pull rod is slidably connected to the inside of the sealing plate. A spring is sleeved on the outer surface of the support rod near the sealing plate and the slip ring. A sliding groove is fixedly connected to the bottom of the support rod. A slider is slidably connected to the inner wall of the sliding groove. The side of the slider away from the support rod contacts the inner wall of the storage bin. A connecting rod is rotatably connected to the top of the slider via a pin. The side of the connecting rod away from the slider is rotatably connected to the outer surface of the slip ring via a pin. The spring force allows the sealing plate to make tight contact with the feed inlet, sealing the storage bin and preventing rainwater penetration that could cause the grain to become damp and moldy, thus greatly improving the waterproof performance of the equipment.

[0007] Furthermore, a discharge port is fixedly connected to the bottom of the storage bin, a fan is installed below the storage bin, and an air duct is fixedly connected to the air outlet at the top of the fan. The air duct is arranged in a ring shape, which can ensure that the air blown by the fan is evenly transmitted into the air duct to a large extent, thereby ensuring that the inside of the storage bin is fully ventilated and improving the practicality of the equipment.

[0008] Furthermore, two air ducts are fixedly connected to the top of the air duct, and an air outlet is fixedly connected to the top of the air duct. Several small holes are opened on the outer surface of the air duct on the side inside the storage compartment. The holes on the outer surface of the air duct can fully allow the air inside the storage compartment to be discharged through the air outlet, thereby improving the ventilation efficiency and further improving the waterproof effect of the equipment.

[0009] Furthermore, the top of the duct penetrates through the bottom of the storage compartment and extends into the interior, while the top of the air outlet penetrates through the top of the storage compartment and extends to the outside. The air outlet opens downwards, which can effectively prevent rainwater from entering the duct and flowing into the storage compartment and the fan. This not only further improves the waterproof performance of the equipment but also greatly enhances its safety.

[0010] Furthermore, a support plate is fixedly connected to the outer surface of the two air ducts, and a baffle is fixedly connected to the top of the support plate. The baffle can prevent grain from falling onto the support plate when it is being transported to the storage bin, thereby affecting the operation of the parts on the support plate and improving the stability of the device.

[0011] Furthermore, a gear is rotatably connected to the top center of the support plate, and a motor is fixedly connected to the top of the support plate via a support frame. The bottom output end of the motor is fixedly connected to the top of the gear. Racks are meshed with both the front and back of the gear. Moisture-proof plates are fixedly connected to the sides of the two racks near the air duct. The outer surface of the moisture-proof plate contacts the inner wall of the air duct. A slit is opened on the side of the air duct near the moisture-proof plate. When ventilation is not required, the moisture-proof plate can prevent external humid air from entering the storage chamber through the air duct, thus preventing the storage chamber from becoming damp and causing the grain to mold. This further improves the waterproofness of the equipment.

[0012] Furthermore, the side of the rack away from the gear contacts a limiting frame, the bottom of which is fixedly connected to the top of the support plate. The limiting frame can prevent the rack from shifting during movement, thus preventing the moisture-proof plate from being stably inserted into the inner wall of the air duct, thereby further improving the stability of the equipment.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model uses a sealing plate. Specifically, the spring force on the outer surface of the support rod causes the slip ring to descend, sliding downwards on the outer surface of the support rod. This causes the two connecting rods to move away from each other. Then, the slider at the bottom of the connecting rod slides inside the groove, causing the side of the slider away from the support rod to contact the inner wall of the storage compartment, thus sealing the storage compartment. The spring ensures that the sealing plate is in close contact with the feed inlet to prevent rainwater from seeping in. This greatly improves the waterproof performance and avoids the threat to human health caused by grain mold.

[0015] 2. This utility model, by setting up a moisture-proof plate, specifically, when there is no need to ventilate the storage, the motor is started, causing the motor to drive the gear to rotate, so that the two racks move away from each other, and the outer surface of the moisture-proof plate contacts the inner wall of the air duct. This can prevent external humid air from entering the storage silo and causing the grain to mold, and further improves the waterproof performance of the equipment.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figure 1-5As shown, this utility model is a sealed and waterproof structure for grain storage equipment, including a storage bin 1 and a feed inlet 11. The bottom of the feed inlet 11 is fixedly connected to the top of the storage bin 1. A sealing plate 111 is inserted into the top of the feed inlet 11. The outer surface of the sealing plate 111 contacts a bin cover 112. A support rod 113 is fixedly connected to the bottom of the sealing plate 111. A slip ring 114 is slidably connected to the outer surface of the support rod 113. A pull rod 115 is fixedly connected to the top of the slip ring 114. A handle 116 is fixedly connected to the top of the pull rod 115. The top of the pull rod 115 passes through the sealing plate 111 and extends to the outside. The outer surface of the pull rod 115 is slidably connected to the inside of the sealing plate 111. A spring is sleeved on the side of the outer surface of the support rod 113 near the sealing plate 111 and the slip ring 114. A sliding groove 118 is fixedly connected to the bottom of the support rod 113. A slider 1 is slidably connected to the inner wall of the sliding groove 118. 19. The side of slider 119 away from support rod 113 contacts the inner wall of storage bin 1. The top of slider 119 is rotatably connected to connecting rod 117 via a pin. The side of connecting rod 117 away from slider 119 is rotatably connected to the outer surface of slip ring 114 via a pin. By setting sealing plate 111, specifically because the spring force on the outer surface of support rod 113 causes slip ring 114 to descend, slip ring 114 slides downward on the outer surface of support rod 113, causing the two connecting rods 117 to move away from each other. Then, slider 119 at the bottom of connecting rod 117 slides inside slide groove 118, causing the side of slider 119 away from support rod 113 to contact the inner wall of storage bin 1, thus sealing storage bin 1. The spring makes sealing plate 111 in close contact with feed inlet 11 to prevent rainwater from seeping in, which greatly improves waterproof performance and avoids the threat to human health caused by grain mold.

[0027] The bottom of the storage chamber 1 is fixedly connected to the discharge port 15, and a fan 12 is installed below the storage chamber 1. The top air outlet of the fan 12 is fixedly connected to the air duct 13, which is arranged in a ring.

[0028] Two air ducts 14 are fixedly connected to the top of the air duct 13. An air outlet 16 is fixedly connected to the top of the air duct 14. Several small holes are opened on the outer surface of the air duct 14 on the side inside the storage compartment 1.

[0029] The top of the air duct 14 passes through the bottom of the storage compartment 1 and extends into the interior, while the top of the air outlet 16 passes through the top of the storage compartment 1 and extends into the exterior.

[0030] Support plates 141 are fixedly connected to the outer surfaces of the two air ducts 14, and baffles 147 are fixedly connected to the top of the support plates 141.

[0031] A gear 142 is rotatably connected to the top center of the support plate 141. A motor 143 is fixedly connected to the top of the support plate 141 via a support frame. The bottom output end of the motor 143 is fixedly connected to the top of the gear 142. Gear racks 144 are meshed on both the front and back of the gear 142. Moisture-proof plates 145 are fixedly connected to the side of each rack 144 near the air duct 14. The outer surface of the moisture-proof plate 145 contacts the inner wall of the air duct 14. A cut is made on the side of the air duct 14 near the moisture-proof plate 145. By setting the moisture-proof plate 145, when there is no need to ventilate the storage 1, the motor 143 is started, causing the motor 143 to drive the gear 142 to rotate, so that the two racks 144 move away from each other and the outer surface of the moisture-proof plate 145 contacts the inner wall of the air duct 14. This can prevent external humid air from entering the storage 1 and causing the grain to mold, and further improves the waterproof performance of the equipment.

[0032] The side of the rack 144 away from the gear 142 contacts the limit frame 146, and the bottom of the limit frame 146 is fixedly connected to the top of the support plate 141.

[0033] A specific application of this embodiment is as follows: When grain needs to be stored, remove the cover 112 to detach it from the outer surface of the sealing plate 111. Then pull the handle 116 to make the pull rod 115 slide inside the sealing plate 111. At this time, the pull rod 115 drives the slip ring 114 to slide upward on the outer surface of the support rod 113, so that the two connecting rods 117 move closer to each other. Then, the slider 119 at the bottom of the connecting rod 117 slides inside the groove 118, so that the side of the slider 119 away from the support rod 113 is separated from the inner wall of the storage bin 1. Then, remove the sealing plate 111 and transport the grain from the feed inlet 11 into the storage bin 1. After the transport is completed, similarly pull the handle 116 to insert the sealing plate 111 into the top of the feed inlet 11. After releasing the handle 116, the spring force on the outer surface of the support rod 113 causes the slip ring 114 to descend, so that the side of the slider 119 away from the support rod 113 contacts the inner wall of the storage bin 1, fixing the sealing plate 111 and completing the sealing of the storage bin 1. The spring keeps the sealing plate The inlet 11 is in close contact with the sealing plate 11 to prevent rainwater from seeping in. Then, the cover 112 is placed on top of the sealing plate 111, so that the inner wall of the cover 112 contacts the outer surface of the sealing plate 111. The cover 112 can prevent rainwater from contacting the contact surface between the sealing plate 111 and the inlet 11, thus preventing rainwater from seeping in. A fan 12 is installed at the bottom of the storage silo 1. When ventilation of the storage silo 1 is required, the motor 143 is started first, causing the motor 143 to drive the gear 142 to rotate, so that the two gears... When strips 144 are brought closer together, the moisture-proof board 145 is separated from the inner wall of the air duct 14. The fan 12 is started to send air through the air duct 13 into the air duct 14. The annular air duct evenly sends air into the two air ducts 14. Several small holes on the outer surface of the air duct 14 allow the air inside the storage chamber 1 to be discharged through the air outlet 16. After ventilation is completed, the motor 143 is started to make the outer surface of the moisture-proof board 145 contact the inner wall of the air duct 14, which can prevent external humid air from entering the storage chamber 1.
