Description

Technical Field

[0001] This utility model belongs to the technical field of rice milling equipment, specifically relating to a rice milling cooling device. Background Technology

[0002] Rice milling is a processing method that removes the husk and bran from paddy rice to make it into white rice. This process usually includes cleaning, hulling, whitening, finishing, packaging, and storage. Hulling removes the husk from the paddy rice to obtain brown rice, while whitening removes the bran from the brown rice to obtain white rice.

[0003] The development of rice milling technology has progressed from manual milling to mechanized and automated milling. With technological advancements, modern rice milling equipment can achieve efficient and precise milling processes, greatly improving production efficiency and product quality. However, during prolonged rice milling operations, the equipment generates a significant amount of heat. If this heat is not dissipated in time, it can lead to excessively high rice temperatures, causing excessive moisture evaporation from the rice grains, hindering the rice mill's bran removal, increasing its load, and resulting in uneven milling. Furthermore, excessively high temperatures can damage the rice mill's components, shortening its lifespan. Traditional rice milling machinery typically relies solely on ventilation holes on the machine casing for heat dissipation, which suffers from poor heat dissipation performance. Therefore, this application proposes a rice milling cooling device. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a rice milling cooling device, which aims to solve the technical problem of poor heat dissipation effect of rice milling machines under the existing technology.

[0005] Technical solution

[0006] To solve the above-mentioned technical problems, this utility model provides a rice milling cooling device, including an air inlet frame mounted on the top of the rice milling machine body and an exhaust pipe mounted on the bottom of the rice milling machine body. The air inlet frame penetrates the top shell of the rice milling machine body, and a mesh plate is provided at one end of the air inlet frame located outside the rice milling machine body. The exhaust pipe penetrates the bottom shell of the rice milling machine body, and a fan is installed inside the exhaust pipe. A lower partition mesh is provided at both the end of the exhaust pipe located inside the rice milling machine body and the end located outside the rice milling machine body.

[0007] Preferably, vertical arms are fixed at each of the four corners of the exhaust pipe, and the bottom of the vertical arms extends to the bottom of the exhaust pipe.

[0008] Preferably, a support arm is horizontally fixed between the bottom ends of the two vertical arms located at the same end of the exhaust pipe, and the support arm is provided with mounting holes.

[0009] Preferably, multiple sets of air intake frames are provided, and the multiple sets of air intake frames are distributed on the top of the side wall of the rice milling machine and on the top wall of the rice milling machine.

[0010] Preferably, the air intake frame has protrusions at both ends, and the mesh plate is detachably connected to the protrusions.

[0011] Preferably, the mesh panel consists of an outer frame and an upper partition mesh assembled inside the outer frame. The outer frame has protrusions at both ends, the protrusions are aligned with the boss, and the protrusions have through holes. A magnetic post is movably inserted into the through hole, and the boss has a plug hole that can accommodate the magnetic post.

[0012] Preferably, the bottom end of the boss is provided with a magnetic block that magnetically engages with the magnetic post, the top end of the magnetic post is connected with a plug post, the diameter of the plug post is larger than the diameter of the through hole, and the top end of the plug post is provided with an end piece.

[0013] Beneficial effects

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention, through the design of an air inlet frame and an exhaust pipe, allows the fan inside the exhaust pipe to draw air out of the rice milling machine during the rice milling process, creating negative pressure within the machine. Outside air can then enter the machine through the air inlet frame, forming an airflow circulation inside and outside the machine. This rapidly dissipates the heat generated during operation, achieving efficient heat dissipation and effectively preventing damage to internal components due to overheating, as well as quality problems caused by excessively high rice temperatures.

[0016] This invention, through the arrangement of the mesh plate and the lower partition mesh, allows the mesh plate at the top of the air inlet frame to block external dust and impurities from entering the rice milling machine during the heat dissipation process. The lower partition mesh at the top of the exhaust pipe can also block rice bran from being discharged from the exhaust pipe as much as possible, reducing the impact of dust and impurities on the equipment. In addition, by inserting a magnetic column through the through hole into the plug hole and magnetically attracting the magnetic block at the bottom of the boss, the mesh plate can be quickly assembled onto the air inlet frame. Furthermore, by holding the plug and the end piece and pulling the magnetic column away from the boss, the mesh plate can be removed from the air inlet frame. This structure makes the installation and removal of the mesh plate convenient and facilitates the disassembly and cleaning of the mesh plate. Attached image description:

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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 protection scope of the present utility model.

[0027] This embodiment provides a rice milling cooling device, the structural schematic diagram of which is shown below. Figures 1-7As shown, the rice milling machine includes an air inlet frame 2 mounted on the top of the rice milling machine body 1 and an exhaust pipe 3 mounted on the bottom of the rice milling machine body 1. The air inlet frame 2 penetrates the top casing of the rice milling machine body 1, and a mesh plate 4 is provided at the end of the air inlet frame 2 located outside the rice milling machine body 1. The exhaust pipe 3 penetrates the bottom casing of the rice milling machine body 1, and a fan 7 is installed inside the exhaust pipe 3. A lower partition 8 is provided at both the end of the exhaust pipe 3 located inside the rice milling machine body 1 and the end located outside the rice milling machine body 1. During the rice milling process, the fan 7 inside the exhaust pipe 3 is activated to draw air out of the rice milling machine body 1, creating a negative pressure inside the rice milling machine body 1. Outside air can enter the rice milling machine body 1 through the air inlet frame 2, forming an airflow circulation inside and outside the rice milling machine body 1. This can quickly dissipate the heat generated by the rice milling machine body 1 during operation, achieving the purpose of efficient heat dissipation of the rice milling machine body 1. This can effectively prevent damage caused by excessive temperature of internal components of the rice milling machine body 1 and quality problems caused by excessive rice temperature. In addition, during the heat dissipation process of the rice milling machine body 1, the mesh plate 4 on the top of the air inlet frame 2 can block external dust and impurities from entering the rice milling machine body 1, the lower partition 8 on the top of the exhaust pipe 3 can block rice bran from being discharged from the exhaust pipe 3 as much as possible, reducing the impact of dust and impurities on the equipment, and the lower partition 8 at the bottom of the exhaust pipe 3 can block external mosquitoes from entering the rice milling machine body 1.

[0028] Furthermore, vertical arms 9 are fixed at each of the four corners of the exhaust pipe 3, with the bottom of the vertical arms 9 extending below the exhaust pipe 3 to provide suspension support for the rice milling machine body 1 and ensure that the hot air at the bottom of the exhaust pipe 3 can be smoothly dissipated. A support arm 10 is horizontally fixed between the bottom ends of the two vertical arms 9 located at the same end of the exhaust pipe 3, and the support arm 10 has mounting holes 11 for mounting and fixing the rice milling machine body 1.

[0029] Furthermore, multiple sets of air intake frames 2 are provided, which are distributed on the top of the side wall of the rice milling machine body 1 and on the top wall of the rice milling machine body 1. This can disperse the air intake at the top of the rice milling machine body 1 and improve the heat dissipation effect on the rice milling roller inside the rice milling machine body 1.

[0030] In a further embodiment, protrusions 5 are provided at both ends of the air intake frame 2. The mesh plate 4 is detachably connected to the protrusions 5. The mesh plate 4 consists of an outer frame 16 and an upper partition mesh 17 assembled inside the outer frame 16. Protrusions 18 are provided at both ends of the outer frame 16. The protrusions 18 are aligned with the protrusions 5, and through holes 19 are provided on the protrusions 18. A magnetic post 14 is movably inserted into the through hole 19. The protrusions 5 are provided with insertion holes 12 that can accommodate the magnetic post 14. The bottom end of the protrusions 5 is provided with a magnetic connection point to the magnetic post 14. The magnetic block 13 and the magnetic column 14 are connected to the top of the insertion post 6. The diameter of the insertion post 6 is larger than the diameter of the through hole 19. The top of the insertion post 6 is provided with an end piece 15. The magnetic column 14 passes through the through hole 19 and is inserted into the insertion hole 12 to magnetically attract the magnetic block 13 at the bottom of the boss 5. This allows the mesh plate 4 to be quickly assembled onto the air intake frame 2. By holding the insertion post 6 and the end piece 15, the magnetic column 14 can be pulled away from the boss 5, and the mesh plate 4 can be removed from the air intake frame 2. The mesh plate 4 is easy to install and remove, which is beneficial for the disassembly and cleaning operation of the mesh plate 4.

[0031] Working principle: During the rice milling process in the rice milling machine body 1, the fan 7 in the exhaust pipe 3 is activated to draw air out of the rice milling machine body 1, creating negative pressure inside the rice milling machine body 1. Outside air can enter the rice milling machine body 1 through the air inlet frame 2, forming an airflow circulation inside and outside the rice milling machine body 1. This can quickly dissipate the heat generated by the rice milling machine body 1 during operation, achieving the purpose of efficient heat dissipation for the rice milling machine body 1, preventing damage caused by excessive temperature of internal components and quality problems caused by excessively high rice temperature. Furthermore, during the heat dissipation process of the rice milling machine body 1, the mesh plate 4 on the top of the air intake frame 2 can prevent external dust and impurities from entering the rice milling machine body 1, and the lower partition mesh 8 on the top of the exhaust pipe 3 can prevent rice bran from being discharged from the exhaust pipe 3 as much as possible. In addition, by inserting the magnetic column 14 through the through hole 19 into the insertion hole 12 and magnetically attracting the magnetic block 13 at the bottom of the boss 5, the mesh plate 4 can be quickly assembled onto the air intake frame 2. Moreover, by holding the insertion column 6 and the end piece 15 and pulling the magnetic column 14 away from the boss 5, the mesh plate 4 can be removed from the air intake frame 2. With this structure, the mesh plate 4 is easy to install and remove, which is conducive to the disassembly and dust removal operation of the mesh plate 4.
