Description

Technical Field

[0001] This utility model relates to the field of rice drying, and in particular to a high-efficiency and energy-saving rice seed drying device. Background Technology

[0002] Rice needs to be kept dry during storage or transportation; otherwise, it may become moldy during storage, affecting the germination rate. During processing, rice needs to undergo a drying process to reduce the moisture content inside the seeds due to its high internal water content.

[0003] Chinese patent announcement number CN217636647U discloses a drying device for uniformly preventing damage to rice, including a drying box. The drying box has a discharge port on its top side, a hot air pipe connected to the bottom side, and a discharge port on its bottom side. A vibrating net is connected to the inner wall of the drying box via a vibrating assembly. The vibrating assembly includes a vertical groove inside the drying box, a vertical rod installed between the top and bottom walls of the groove, and vibrating springs sleeved on the outside of the vertical rods connected to the top and bottom sides of the groove. Sliding blocks are installed on opposite sides of the two vibrating springs and are slidably connected to the vertical rods. Support frames are hinged to the two sliding blocks, and the other ends of the two support frames are hinged to the vibrating net. In use, this invention repeatedly tumbles the rice on multiple vibrating nets, thus better drying the rice and improving the drying effect.

[0004] However, this device has the following drawbacks: While it allows the rice to tumble repeatedly on multiple vibrating screens for better drying, when the rice has high moisture content, the excessive moisture after tumbling and falling to the bottom of the drying drum prevents it from drying completely. Furthermore, the accumulation of incompletely dried rice reduces the drying efficiency. To address these shortcomings, we propose a high-efficiency, energy-saving rice seed drying device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a highly efficient and energy-saving rice seed drying device.

[0006] To address the problems existing in the prior art, this utility model adopts the following technical solution: a high-efficiency and energy-saving rice seed drying device, comprising:

[0007] The equipment housing includes a cylindrical body, a feed pipe fixedly installed on the surface of the cylindrical body, and a feed funnel fixedly installed on the surface of the feed pipe;

[0008] A drying structure, the drying structure including a heat source assembly disposed on the surface of the cylinder and a material agitation assembly disposed inside the cylinder;

[0009] The heat source assembly includes a heat source fan and an exhaust pipe fixedly installed at the exhaust end of the heat source fan, with the other end of the exhaust pipe connected to the interior of the cylinder.

[0010] The material agitation assembly includes a conveying cylinder fixedly installed on the inner wall of the cylinder, a conveying auger rotatably installed on the inner wall of the conveying cylinder, a conical diffuser plate fixedly installed on the surface of the conveying cylinder, and a conical collecting plate fixedly installed on the surface of the conveying cylinder, wherein a material leakage groove is provided on the surface of the conical collecting plate, and a motor that can drive the conveying auger to rotate is fixedly installed at the lower end of the cylinder.

[0011] A discharge structure is provided above the cylinder body to discharge materials inside the cylinder body.

[0012] Preferably, the lower end of the conveying cylinder has a feed inlet, the upper end of the conveying cylinder extends to the outside of the cylinder body and has a discharge outlet, and the upper end of the cylinder body has a leakage channel.

[0013] Preferably, the cone-shaped diffuser plate is narrower at the top and wider at the bottom, and the cone-shaped collecting plate is wider at the top and narrower at the bottom.

[0014] Preferably, the discharge structure includes a protective cover fixedly installed on the upper end of the cylinder, a sliding groove opened on the upper end of the protective cover, a discharge cylinder slidably installed on the inner wall of the sliding groove, a discharge pipe fixedly installed on the surface of the discharge cylinder, a drive component provided on the upper end of the protective cover for driving the discharge cylinder to move, and a dust removal component provided on the surface of the protective cover.

[0015] Preferably, the drive assembly includes a support frame fixedly installed on the upper end of the cylinder, and an electric telescopic rod fixedly installed on the upper end of the support frame, wherein the telescopic end of the electric telescopic rod is fixedly connected to the upper end of the discharge cylinder.

[0016] Preferably, a valve is fixedly installed on the surface of the discharge pipe, and a retaining ring is fixedly installed on the surface of the discharge cylinder.

[0018] Preferably, the inner bottom wall of the cylinder is conical.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. By setting up a drying structure, when rice enters the drum, it will accumulate at the bottom of the drum. Then, hot air can be introduced into the drum using a heat source component. After that, the drive motor can drive the rice to enter the inside of the conveying drum through the feed inlet. The rotating conveying auger will transport the material along the conveying drum to its top and fall into the drum through the discharge outlet. When the rice flows back into the drum, the material will pass through the conical diffuser plate and the conical collecting plate to diffuse, collect and disperse the rice. This will fully disperse the rice and slow it down when it comes into contact with the conical diffuser plate and the conical collecting plate. After repeated cycles, the rice with high moisture content can be dried efficiently, improving the rice drying efficiency.

[0021] 2. By setting up a discharge structure, after the rice is dried, the electric telescopic rod is driven to descend, so that the lower end of the discharge cylinder contacts the upper end of the cylinder. The discharge cylinder can isolate the leakage channel, so that the material can enter the discharge cylinder along the conveying cylinder and be discharged from the cylinder along the discharge pipe, thus facilitating the discharge of rice.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] Please see Figure 1-4 This utility model provides a technical solution: a high-efficiency and energy-saving rice seed drying device, including: an equipment shell, a drying structure and a discharge structure.

[0031] See Figure 1 The equipment housing includes a cylinder 10, a feed pipe 11 fixedly installed on the surface of the cylinder 10, and a feed funnel 12 fixedly installed on the surface of the feed pipe 11. The inner bottom wall of the cylinder 10 is set in a conical shape. Rice is poured into the feed funnel 12, and then the rice will enter the cylinder 10 along the feed pipe 11.

[0032] See Figure 3 The drying structure includes a heat source assembly disposed on the surface of the cylinder 10 and a material agitation assembly disposed inside the cylinder 10.

[0033] The heat source assembly includes a heat source fan 20 and an exhaust pipe 21 fixedly installed at the exhaust end of the heat source fan 20. The other end of the exhaust pipe 21 is connected to the interior of the cylinder 10. Driving the heat source fan 20 can allow the hot air generated by the heat source fan 20 to enter the cylinder 10 along the exhaust pipe 21.

[0034] See Figure 3-5 The material agitation assembly includes a conveying cylinder 30 fixedly installed on the inner wall of the cylinder 10, a conveying auger 31 rotatably installed on the inner wall of the conveying cylinder 30, a conical diffuser plate 32 fixedly installed on the surface of the conveying cylinder 30, and a conical collecting plate 33 fixedly installed on the surface of the conveying cylinder 30. The surface of the conical collecting plate 33 is provided with a material leakage groove. A motor 34 that can drive the conveying auger 31 to rotate is fixedly installed at the lower end of the cylinder 10.

[0035] The lower end of the conveying cylinder 30 is provided with a feed inlet 40, and the upper end of the conveying cylinder 30 extends to the outside of the cylinder body 10 and is provided with a discharge outlet 41. The upper end of the cylinder body 10 is provided with a leakage channel 42. When rice enters the cylinder body 10, the drive motor 34 can drive the conveying auger 31 to rotate. The rice in the cylinder body 10 will enter the conveying cylinder 30 along the feed inlet 40. Then, the rotating conveying auger 31 can transport the material along the conveying cylinder 30 to its top and fall back into the cylinder body 10 along the discharge outlet 41 and the leakage channel 42.

[0036] See Figure 3The conical diffuser plate 32 is designed to be narrower at the top and wider at the bottom, while the conical collecting plate 33 is designed to be wider at the top and narrower at the bottom. When the rice flows back into the cylinder 10, the material will pass through the conical diffuser plate 32 and the conical collecting plate 33 to diffuse, collect, and disperse the rice. This fully disperses the rice and slows it down when it comes into contact with the conical diffuser plate 32 and the conical collecting plate 33. The rice is repeatedly lifted and circulated, which can efficiently dry rice with high moisture content, thus improving the efficiency of rice drying.

[0037] See Figure 2 , Figure 3 and Figure 5 The discharge structure is located above the cylinder 10 and is used to discharge the material inside the cylinder 10. The discharge structure includes a protective cover 50 fixedly installed on the upper end of the cylinder 10, a sliding groove opened on the upper end of the protective cover 50, a discharge cylinder 51 slidably installed on the inner wall of the sliding groove, a discharge pipe 52 fixedly installed on the surface of the discharge cylinder 51, a drive component set on the upper end of the protective cover 50 for driving the discharge cylinder 51 to move, and a dust removal component set on the surface of the protective cover 50. A valve 70 is fixedly installed on the surface of the discharge pipe 52.

[0038] The drive assembly includes a support frame 60 fixedly installed on the upper end of the cylinder 10, and an electric telescopic rod 61 fixedly installed on the upper end of the support frame 60. The telescopic end of the electric telescopic rod 61 is fixedly connected to the upper end of the discharge cylinder 51. After the rice is dried, the electric telescopic rod 61 is driven to descend, so that the lower end of the discharge cylinder 51 contacts the upper end of the cylinder 10. The discharge cylinder 51 can isolate the leakage channel 42, so that the material can enter the discharge cylinder 51 along the conveying cylinder 30 and be discharged into the cylinder 10 along the discharge pipe 52, thus facilitating the discharge of rice.

[0039] See Figure 2 and Figure 5 The dust removal assembly includes a dust removal pipe 90 fixedly installed on the surface of the protective cover 50, and a vacuum cleaner 91 fixedly installed at the other end of the dust removal pipe 90. A retaining ring 80 is fixedly installed on the surface of the discharge cylinder 51. The retaining ring 80 can improve the sealing between the discharge cylinder 51 and the protective cover 50. When the rice is dried, the vacuum cleaner 91 can discharge the dust in the cylinder 10 along the dust removal pipe 90.

[0040] Working principle:

[0041] First, the rice is poured into the feed funnel 12, and then the rice will enter the cylinder 10 along the feed pipe 11;

[0042] The hot air generated by the heat source fan 20 can enter the cylinder 10 through the exhaust pipe 21;

[0043] The drive motor 34 can drive the conveying auger 31 to rotate. The rice in the cylinder 10 will enter the conveying cylinder 30 along the feed inlet 40. Then, the rotating conveying auger 31 can transport the material along the conveying cylinder 30 to its top, and then fall back into the cylinder 10 along the discharge outlet 41 and the leakage channel 42.

[0044] As the rice flows back into the cylinder 10, the material passes through the conical diffuser plate 32 and the conical collecting plate 33 to diffuse, collect, and disperse the rice. This process fully disperses the rice and slows it down when it comes into contact with the conical diffuser plate 32 and the conical collecting plate 33. The rice is repeatedly lifted and circulated, which can efficiently dry rice with high moisture content.

[0045] When the rice is being dried, the vacuum cleaner 91 can discharge the dust inside the cylinder 10 along the dust removal pipe 90.

[0046] After the rice is dried, the electric telescopic rod 61 is driven to descend, so that the lower end of the discharge cylinder 51 contacts the upper end of the cylinder 10. The discharge cylinder 51 can isolate the leakage channel 42, so that the material can enter the discharge cylinder 51 along the conveying cylinder 30 and be discharged into the cylinder 10 along the discharge pipe 52, thus facilitating the discharge of the rice.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art based on the technical solution and concept of the present utility model should be included within the protection scope of the present utility model.
