Description

Technical Field

[0001] This utility model relates to the field of rice production and rice milling technology, specifically a horizontal rice milling machine that is easy to adjust. Background Technology

[0002] Rice milling is a crucial step in rice production, its main purpose being to remove the husk and bran of the paddy rice to obtain edible rice. With the gradual improvement of living standards, people have placed higher demands on rice quality, leading to rapid improvements in rice milling technology. With the continuous improvement of rice varieties, the yield of long-grain rice has been increasing in recent years. However, this type of rice is prone to breakage during harvesting and threshing due to its inherent characteristics. Traditional rice milling machines, due to their outdated technology, tend to increase the breakage rate. Modern rice milling machines employ a double-roller structure, precisely controlling parameters such as the speed, pressure, and gap between the two rollers to subject the paddy rice to appropriate squeezing and friction between the rollers. This efficiently and accurately removes the husk and reduces damage to the brown rice.

[0003] In the process of developing this utility model, the inventors discovered the following problems with the existing technology: 1. Common horizontal rice milling machines may not have the function of adjusting the feeding speed during the material feeding process, which may lead to the feeding speed being too fast or too slow, resulting in a decrease in subsequent rice milling efficiency; 2. Common horizontal rice milling machines usually use bolts and nuts to fix the outer shell. When it is necessary to clean the internal rice milling rollers, a long disassembly process is required, which is time-consuming, labor-intensive, and inconvenient. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 4 This utility model provides a technical solution: an easily adjustable horizontal rice milling machine, including a support base 1, a box body 2 fixedly connected to the top of the support base 1, a first discharge channel 3 installed on one side of the box body 2, a second discharge channel 4 installed on the front of the box body 2, a rice milling component 5 horizontally penetrating the interior of the box body 2, a box cover 7 installed on the top of the box body 2 through a quick-connect component 6, a feeding hopper 8 installed at the top center of the box cover 7, and an adjusting component 9 horizontally penetrating the interior of the feeding hopper 8.

[0024] The rice milling assembly 5 includes a motor 501 rotatably connected to one side of the housing 2. The output shaft of the motor 501 passes horizontally through the interior of the main gear 502 and is connected to the main rice milling roller 503. A secondary gear 504 meshes with the outer side of the main gear 502, and a secondary rice milling roller 505 passes horizontally through the interior of the secondary gear 504.

[0025] The quick-connect assembly 6 includes a bracket 601 fixedly connected to the center of the front of the housing 2. One end of the bracket 601 passes horizontally through a limit rod 602, and one end of the limit rod 602 passes horizontally through the inside of a spring 603 and is connected to a limit block 604.

[0026] The adjusting component 9 includes fixed blocks 901 fixedly connected to both sides of the front of the feed hopper 8, a bidirectional lead screw 902 horizontally passing through the fixed blocks 901, a handle 903 fixedly connected to one end of the bidirectional lead screw 902, threaded collars 904 installed on both sides of the outer side of the bidirectional lead screw 902, and an adjusting plate 905 fixedly connected to one end of the outer side of the threaded collar 904.

[0027] In this embodiment, as Figure 1 As shown, fans are evenly installed on the back of the housing 2. This design allows the brown rice and husks after passing through the rice milling component 5 to be separated by the fans due to their different weights. This allows the brown rice and husks to be unloaded through different discharge channels, thus ensuring the effectiveness of the rice milling process.

[0028] In this embodiment, as Figure 1 As shown, an inclined baffle is fixedly connected inside the box 2; this design allows the brown rice to move through the inclined baffle, thereby effectively discharging it and avoiding material accumulation that could cause blockage, thus improving unloading efficiency.

[0029] In this embodiment, as Figure 1 and Figure 2 As shown, the motor 501, main gear 502, and main rice milling roller 503 form a rotating structure, and the main gear 502 and auxiliary gear 504 form a meshing transmission structure. Through this design, the main rice milling roller 503 and auxiliary rice milling roller 505 can rotate in opposite directions, so that the material can be subjected to forces from two opposite directions, thereby ensuring that the rice milling process can be carried out effectively. Furthermore, the material can be more fully tumbled and rubbed, allowing the material to make uniform contact with the main rice milling roller 503 and auxiliary rice milling roller 505, thereby ensuring higher dehulling efficiency and better quality of the material.

[0030] In this embodiment, as Figure 1 and Figure 3As shown, the spring 603 and the limiting block 604 form an elastic structure, and a connecting block is fixedly connected to the center of one side of the lid 7. The connecting block has a slot with the same shape as the limiting block 604. Meanwhile, the other side of the lid 7 is connected to the top of the box body 2 by a hinge. The front of the box body 2 has a groove with the same shape as the limiting block 604 at the contact point with the limiting block 604. This design allows the lid 7 to be opened and closed quickly. Compared with the previous bolt and nut fixing method, this design makes the whole process easier, saving the workers' working time and reducing their labor, so as to facilitate the cleaning process of the internal rice milling component 5, thereby ensuring that the efficiency and quality of subsequent rice milling can be well maintained, and increasing convenience.

[0031] In this embodiment, as Figure 1 and Figure 4 As shown, the bidirectional lead screw 902 and the handle 903 form a rotating structure, and the bidirectional lead screw 902, the threaded collar 904, and the adjusting plate 905 form a linkage structure. This design allows for the adjustment of the opening and closing size of the feed inlet in the feed hopper 8, thereby allowing for the adjustment of the feeding speed. This can be adjusted according to the corresponding rice milling efficiency, reducing the occurrence of poor rice milling results during the rice milling process, increasing rice milling efficiency while ensuring rice milling quality, thus providing effective assistance for subsequent production and processing.

[0032] In this embodiment, as Figure 1 As shown, both the first discharge channel 3 and the second discharge channel 4 are inclined. This design allows the brown rice and husks to be discharged more smoothly through the first discharge channel 3 and the second discharge channel 4, avoiding blockages and improving unloading efficiency.

[0033] The usage and advantages of this utility model: This easily adjustable horizontal rice milling machine operates as follows:

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the material is first poured into the housing 2 through the feed hopper 8. The motor 501 is then turned on, and its output shaft drives the main gear 502 and the main rice milling roller 503 to rotate. This causes the auxiliary gear 504, which meshes with the main gear 502, to drive the auxiliary rice milling roller 505 to rotate. At this time, the main rice milling roller 503 and the auxiliary rice milling roller 505 rotate in opposite directions, thus performing the dehulling process. During the dehulling process, the blower is turned on. Due to the weight difference between the brown rice and the outer husk, the outer husk is blown out and discharged from the second discharge channel 4, while the brown rice falls onto the inclined baffle and then flows out from the first... The material is discharged through the discharge channel 3. When the feeding speed needs to be adjusted, the rotating handle 903 drives the bidirectional lead screw 902 to rotate, which causes the threaded collars 904 on both sides to move the adjusting plate 905, thereby adjusting the opening and closing size of the feed inlet of the feed hopper 8 and thus adjusting the feeding speed. When cleaning is required after work, the limit lever 602 is pulled. At this time, the spring 603 will undergo elastic deformation, causing the limit block 604 to disengage from the groove in the box 2 and then pass through the slot of the connecting block on one side of the box cover 7. At this time, the box cover 7 can be opened to clean the inside.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
