Description

Technical Field

[0001] This utility model belongs to the field of food processing technology and relates to a vertical rice fluffing machine. Background Technology

[0002] To meet the dining needs of employees in large enterprises, especially in terms of cooking rice, large-scale rice cooking equipment was developed. First, the washed rice is put into the lunch box in batches, the lid is closed, and the rice is steamed. After steaming, the rice usually needs to be fluffed to make it soft. However, in the past, fluffing the rice was done manually by using a large iron shovel to turn it over. This operation increased labor costs and was inefficient. In addition, because it was done manually, the rice was not fluffed evenly.

[0003] Patent application (CN201220727842.3) discloses a rice dispensing machine, including a dispensing mechanism and a conveying mechanism. The conveying mechanism is located below the dispensing mechanism. The hopper of the dispensing mechanism is installed on the upper part of the support. A rice loosening and opening / closing mechanism is provided at the bottom opening of the hopper. The rice loosening and opening / closing mechanism is connected to the receiving hopper. An adjusting box is installed on the lower part of the support and is directly opposite the receiving hopper. The lower part of the adjusting box is provided with a horizontally installed upper plate and a lower plate. The upper and lower plates are controlled to open and close by an upper plate cylinder and a lower plate cylinder fixed on the support, respectively. The space volume formed between the upper and lower plates is the unit volume required for dispensing rice. The rice boxes carried by the conveying mechanism pass through the bottom of the adjusting box in sequence.

[0004] Because the rice fluffing mechanism is fixed to the equipment, it cannot be disassembled for cleaning after the rice fluffing work is finished, making it inconvenient and difficult to clean the rice fluffing mechanism thoroughly. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a vertical rice fluffing machine that is easy to clean.

[0006] The objective of this utility model can be achieved through the following technical solution: a vertical rice fluffing machine, comprising:

[0007] The frame has two platforms along its height. One platform serves as a conveying platform for the turnover box, and the other is an installation platform. The installation platform is positioned vertically above the conveying platform, and a trough is provided on the installation platform. The loosened rice enters the turnover box on the conveying platform through the trough.

[0008] The rice fluffing device is detachably connected to the installation platform. The rice fluffing device is equipped with a rice fluffing channel, one end of which is connected to the feed hopper installed on the frame, and the other end of which is connected to the through groove.

[0009] In the above-mentioned vertical rice fluffing machine, the rice fluffing device and the installation platform are either slidably connected or rolled. When the two are rolled, two relatively parallel guide rails are connected to the installation platform, and rollers that roll with the guide rails are provided at the bottom of the rice fluffing device.

[0010] In the above-mentioned vertical rice fluffing machine, a guide slope is provided at one end of each guide rail, so that the distance between the two guide slopes on the two guide rails is slightly greater than the relative distance between the outer edges of the two parallel rollers on the rice fluffing device.

[0011] In the above-mentioned vertical rice fluffing machine, a limiting part is provided at the other end of the guide rail opposite to the guide inclined surface, and the limiting part is connected to the guide rail, or a limiting part is provided on the mounting platform.

[0012] In the above-mentioned vertical rice fluffing machine, the rice fluffing device includes a rice fluffing hopper, and the rice fluffing channel is located in the rice fluffing hopper and extends through the upper and lower sides of the rice fluffing hopper. Rollers are connected to the corners of the bottom of the rice fluffing hopper or to the side of the rice fluffing hopper.

[0013] In the above-mentioned vertical rice fluffing machine, multiple fluffing shafts are arranged in the rice fluffing hopper, and multiple fluffing teeth are arranged along the axial direction of the fluffing shafts. The fluffing teeth on adjacent two fluffing shafts are staggered. One fluffing shaft is the driving shaft, and the remaining fluffing shafts are the driven shafts. The fluffing shaft that serves as the driving shaft and the fluffing shaft that serves as the driven shaft are connected through a transmission structure. The rice fluffing device also includes a drive motor, the output end of which is connected to one end of the fluffing shaft that serves as the driving shaft.

[0014] In the above-mentioned vertical rice fluffing machine, each fluffing shaft is equipped with six strip-shaped teeth, and the included angle between two adjacent teeth is 60 degrees. The edge of each tooth is wavy, and the peaks and troughs of the teeth on two adjacent fluffing shafts are arranged opposite each other.

[0015] In the above-mentioned vertical rice fluffing machine, the two ends of the fluffing shaft pass through the two sides of the rice fluffing hopper, and the transmission structure includes a drive gear connected to one end of the fluffing shaft as the drive shaft and a driven gear connected to one end of the fluffing shaft as the driven shaft, and the drive gear and the driven gear mesh with each other.

[0016] In the above-mentioned vertical rice fluffing machine, the drive motor is slidably connected to the mounting platform through the motor support, and a sliding structure is provided between the motor support and the mounting platform. The sliding structure includes a slide rail installed on the mounting platform and a slider that slides with the slide rail and is connected to the motor support.

[0017] In the aforementioned vertical rice fluffing machine, two sets of fluffing groups are arranged vertically within the rice fluffing hopper, and each set contains multiple fluffing shafts. Each set is driven by a corresponding drive motor. In the upper set of the rice fluffing hopper, the drive shaft is detachably connected to the output end of the corresponding drive motor. In the lower set of the rice fluffing hopper, the drive gear on the drive shaft meshes with the auxiliary gear at the output end of the corresponding drive motor.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] (1) The vertical rice fluffing machine provided by this utility model is detachably connected to the installation platform, so that the rice fluffing device can be removed from the installation platform for cleaning after the work is completed. It is convenient to operate and can clean the rice fluffing device.

[0020] (2) The rice fluffing device and the installation platform are connected by a rolling connection, which further reduces the friction between the rice fluffing device and the installation platform during the disassembly and assembly process. It can also reduce the wear on the bottom of the rice fluffing device and extend the service life of the rice fluffing device. In addition, the rice fluffing device is generally composed of multiple structural components, which makes the entire rice fluffing device heavy and large in size. The rolling connection makes it easier for operators to drag or push the rice fluffing device.

[0021] (3) The guide rail not only enables rolling cooperation with the roller, but also limits the movement trajectory of the roller, so that the roller does not deviate during movement, and avoids the roller falling into the through groove of the installation platform, which would cause the entire rice fluffing device to tip over and damage the entire rice fluffing device.

[0022] (4) By setting a limiting part on the guide rail, the moving distance of the rice fluffing device during installation can be controlled, ensuring that the rice fluffing channel on the rice fluffing device is aligned with the through groove on the installation platform, thus avoiding misalignment between the two and causing rice residue between the rice fluffing device and the installation platform, which would result in waste of rice.

[0023] (5) Multiple loosening shafts are arranged side by side, and the teeth on adjacent loosening shafts are staggered. This way, the rice poured from the feed hopper will not fall directly into the turnover box after entering the rice loosening hopper through the channel. Instead, it will stay in the rice loosening hopper temporarily due to the obstruction of the teeth on the loosening shaft. Then, through the rotation of the loosening shaft, the staggered teeth on adjacent loosening shafts will knead and break up the clumps of rice to form loose rice grains, which will then fall into the turnover box through the channel, thus ensuring the effect of loosening the rice.

[0024] (6) By setting up two sets of loosening groups, the loosening effect of rice can be further improved on the one hand, and the rice can be further prevented from falling directly into the turnover box through the channel, thus improving the reliability of loosening rice.

[0036] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0037] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0038] like Figures 1 to 7 As shown, the present invention provides a vertical rice fluffing machine, comprising:

[0039] The frame 100 has two platforms along its height direction. One platform is a conveying platform 110 for the turnover box, and the other is an installation platform 120. The installation platform 120 is arranged vertically to the conveying platform 110, and a through groove 121 is provided on the installation platform 120. The loosened rice enters the turnover box of the conveying platform 110 through the through groove 121.

[0040] The rice fluffing device 200 is detachably connected to the installation platform 120. The rice fluffing device 200 is provided with a rice fluffing channel, one end of which is connected to the feed hopper 300 installed on the frame 100, and the other end of which is connected to the through groove 121.

[0041] The present invention provides a vertical rice fluffing machine. Since the rice fluffing device 200 and the mounting platform 120 are detachably connected, the rice fluffing device 200 can be removed from the mounting platform 120 for cleaning after the work is completed. The operation is convenient and the rice fluffing device 200 can be cleaned.

[0042] It is worth mentioning that the rice fluffing device 200 is detachably connected to the mounting platform 120, and since the rice fluffing device 200 is located between the feed hopper 300 and the mounting platform 120, the rice fluffing device 200 cannot be directly detached from the mounting platform 120 in a vertical direction. It needs to be moved horizontally and pulled out from between the feed hopper 300 and the mounting platform 120. Therefore, to save time and effort during the pulling process, the rice fluffing device 200 and the mounting platform 120 can be configured as a sliding connection or a rolling connection. Roller connections are generally preferred because they reduce friction between the rice fluffing device 200 and the mounting platform 120 during assembly and disassembly, reduce wear on the bottom of the rice fluffing device 200, and extend its service life. Furthermore, since the rice fluffing device 200 is typically composed of multiple structural components, it is relatively heavy and bulky. Roller connections allow operators to drag or push the rice fluffing device 200 more efficiently and effortlessly.

[0043] Therefore, in this embodiment, the rice fluffing device 200 and the mounting platform 120 are connected by a rolling connection, and two relatively parallel guide rails 122 are connected to the mounting platform 120. A roller 210 that rolls with the guide rails 122 is provided at the bottom of the rice fluffing device 200. The guide rails 122 not only enable the rolling cooperation with the rollers 210, but also limit the movement trajectory of the rollers 210, so that the rollers 210 do not deviate during movement, and prevent the rollers 210 from falling into the through groove 121 of the mounting platform 120, which would cause the entire rice fluffing device 200 to tip over and be damaged.

[0044] Furthermore, due to the weight and size of the rice fluffing device 200, its installation needs to be quick to minimize the time it spends in the operator's hands. The operator should not be forced to hold the device for extended periods due to alignment issues between the guide rails 122 and the rollers 210, as this would hinder installation. Therefore, a guide ramp can be provided at one end of each guide rail 122, with the distance between the two guide ramps on the two guide rails 122 slightly greater than the relative distance between the outer edges of the two parallel rollers 210 on the rice fluffing device 200. This allows the rice fluffing device 200 to be quickly installed into the installation platform 120, saving time and effort.

[0045] Furthermore, a limiting part 123 is provided at the other end of the guide rail 122 relative to the guide slope, and the limiting part 123 is connected to the guide rail 122.

[0046] In this embodiment, by setting a limiting part 123 on the guide rail 122, the moving distance of the rice fluffing device 200 during installation can be controlled, ensuring that the rice fluffing channel on the rice fluffing device 200 is aligned with the through groove 121 on the installation platform 120, thus avoiding misalignment between the two and causing rice residue between the rice fluffing device 200 and the installation platform 120, thereby causing waste of rice.

[0047] It is worth mentioning that the limiting part 123 can also be installed on the installation platform 120, and can also control the assembly stroke of the rice loosening device 200.

[0048] Preferably, the rice fluffing device 200 includes rice fluffing teeth 240 hoppers 220, and the rice fluffing channel is located in the rice fluffing teeth 240 hoppers 220 and passes through the upper and lower sides of the rice fluffing teeth 240 hoppers 220. Rollers 210 are connected to the corners of the bottom of the rice fluffing teeth 240 hoppers 220 or to the side of the rice fluffing teeth 240 hoppers 220, so that the rice fluffing teeth 240 hoppers 220 can move on the guide rail 122 by means of the rollers 210.

[0049] Furthermore, it is pointed out that multiple loosening shafts 230 are provided inside the rice-loosening teeth 240 hopper 220, and multiple teeth 240 are arranged along the axial direction of the loosening shafts 230. One loosening shaft 230 is the driving shaft, and the remaining loosening shafts 230 are the driven shafts. The loosening shaft 230 as the driving shaft and the loosening shaft 230 as the driven shaft are connected by a transmission structure. The rice loosening device 200 also includes a drive motor 250, the output end of which is connected to one end of the loosening shaft 230 as the driving shaft.

[0050] In this embodiment, the loosening shaft 230, which serves as the active shaft, is driven to rotate by the drive motor 250. Since the loosening shaft 230, which serves as the driven shaft, is connected to the loosening shaft 230, which serves as the active shaft, through a transmission structure, all the loosening shafts 230 can rotate synchronously, thereby loosening the rice.

[0051] It is worth mentioning that multiple loosening shafts 230 are arranged side by side, and the teeth 240 on adjacent loosening shafts 230 are staggered. In this way, the rice poured from the feed hopper 300 will not fall directly into the turnover box through the channel 121 after entering the rice loosening tooth 240 hopper 220. Instead, it will stay temporarily in the rice loosening tooth 240 hopper 220 due to the obstruction of the teeth 240 on the loosening shafts 230. Then, through the rotation of the loosening shafts 230, the staggered teeth 240 on the adjacent loosening shafts 230 will knead and break up the clumps of rice, forming loose rice grains, which will then fall into the turnover box through the channel 121, ensuring the effect of loosening the rice.

[0052] Additionally, it is worth mentioning that each loosening shaft 230 is equipped with six strip-shaped teeth 240, with an included angle of 60 degrees between any two adjacent teeth 240. The edges of each tooth 240 are wavy, and the crests and troughs of the wavy edges on adjacent loosening shafts 230 are aligned. That is, the crest position of the tooth 240 on the current loosening shaft 230 corresponds to the trough position of the tooth 240 on its adjacent loosening shaft 230.

[0053] It is worth mentioning that the two ends of the rice-scraping shaft 230 pass through both sides of the rice-scraping teeth 240 and the bucket 220, and the transmission structure includes a drive gear 260 connected to one end of the rice-scraping shaft 230 as the drive shaft, and a driven gear 270 connected to one end of the rice-scraping shaft 230 as the driven shaft. The drive gear 260 and the driven gear 270 mesh with each other to achieve synchronous rotation of multiple rice-scraping shafts 230.

[0054] Furthermore, since the rice fluffing device 200 is detachably connected to the mounting platform 120, it is necessary to minimize the weight and volume of this detachable structure. Because the fluffing shaft 230, driving gear 260, driven gear 270, and roller 210 are all directly or indirectly connected to the rice scraper teeth 240 hopper 220, they are inseparable from each other. However, the drive motor 250, which drives the fluffing shaft 230, is a separable component. That is, when rice fluffing is required, the drive motor 250 can be connected to the fluffing shaft 230, which serves as the driving shaft; when the rice scraper teeth 240 hopper 220 needs cleaning, the drive motor 250 can be disconnected from the fluffing shaft 230, which serves as the driving shaft.

[0055] Furthermore, to facilitate the connection or disconnection between the drive motor 250 and the loosening shaft 230 (which serves as the active shaft), the entire drive motor 250 needs to be configured as a movable connection. Specifically, the drive motor 250 is slidably connected to the mounting platform 120 via a motor support 280, and a sliding structure is provided between the motor support 280 and the mounting platform 120. This sliding structure includes a slide rail 124 mounted on the mounting platform 120 and a slider 125 that slides with the slide rail 124 and is connected to the motor support 280. When loosening rice is required, the motor support 280 is moved, connecting the output end of the drive motor 250 to the loosening shaft 230. When the rice-picking teeth 240 hopper 220 needs to be disassembled for cleaning, the motor support 280 is moved, disconnecting the connection between the output end of the drive motor 250 and the loosening shaft 230.

[0056] It is worth mentioning that the power source for the 250-mount drive motor can be a cylinder or a manually operated push-pull quick clamp.

[0057] Preferably, in order to improve the rice fluffing effect, two sets of fluffing groups distributed vertically can be set up, and each set of fluffing groups has multiple fluffing shafts 230. Each set of fluffing groups is driven by a corresponding drive motor 250.

[0058] In this embodiment, by setting two sets of loosening groups, the loosening effect of rice is further improved on the one hand, and the rice can be further prevented from falling directly into the turnover box through the channel 121 on the other hand, thus improving the reliability of loosening rice.

[0059] It is worth mentioning that, since the drive motor 250 is mounted on the mounting platform 120 via the motor support 280, and the motor support 280 and the mounting platform 120 are connected by a sliding structure, there is a certain height difference between the output end of the drive motor 250 and the mounting platform 120. Therefore, when the current set of loosening groups is located on the upper layer of the rice scraper 240 hopper 220, due to the certain height difference between the loosening group on this layer and the mounting platform 120, the output end of the drive motor 250 can be directly connected to the loosening shaft 230, which serves as the drive shaft on this layer, to drive the drive gear 260 to rotate. However, when the current set of loosening groups is located on the lower layer of the rice scraper 240 hopper 220, although there is also a certain height difference between the loosening group on this layer and the mounting platform 120, this height difference is smaller than the height difference between the output end of the drive motor 250 and the mounting platform 120. As a result, during the translation process, the output end of the drive motor 250 cannot be directly inserted into the loosening shaft on this layer, which serves as the drive shaft. Inside shaft 230, an auxiliary gear 290 needs to be set at the output end of drive motor 250. When rice needs to be loosened, drive motor 250 approaches rice picker 240 hopper 220 under the action of sliding structure, and auxiliary gear 290 and drive gear 260 are meshed vertically. At this time, drive motor 250 can also cause the loosening shaft 230, which is the drive shaft, to rotate through auxiliary gear 290 and drive gear 260. When rice picker 240 hopper 220 needs to be cleaned, drive motor 250 moves away from rice picker 240 hopper 220 under the action of sliding structure. At this time, auxiliary gear 290 and drive gear 260 are disengaged, which does not affect the disassembly of rice picker 240 hopper 220.

[0060] Preferably, the feeding hopper 300 and the frame 100 are also detachably connected, and the feeding hopper 300 can also move on the frame 100. The way the feeding hopper 300 moves with the frame 100 is the same as the way the rice scraper 240 hopper 220 moves with the mounting platform 120, so it will not be described in detail here.

[0061] In this embodiment, the reason why the feed hopper 300 is also configured to be movable is to ensure that the discharge port of the feed hopper 300 can be precisely aligned with the loosening channel in the rice picker tooth 240 hopper 220, so as to avoid rice falling outside the rice picker tooth 240 hopper 220 and causing waste of rice.

[0062] Preferably, a temporary storage platform 130 for placing empty turnover boxes is provided on one side of the conveying platform 110, thereby improving the working efficiency of turnover box operation.
