Description

Technical Field

[0001] This utility model relates to the field of rice milling machine technology, specifically a rice output adjustment mechanism and a rice milling machine. Background Technology

[0002] The rice output adjustment mechanism is a crucial component of a rice milling machine, significantly impacting the quality of the milled rice. It primarily consists of an output housing, a rice baffle plate, a spring, a guide post, and an adjustment assembly. To ensure the stability of the rice baffle plate during production, the guide post of the current adjustment mechanism is fixed to the output housing, with the rice baffle plate slidingly mounted on it. Existing mechanisms only reduce the pressure on the rice baffle plate by releasing the spring through the adjustment assembly; they do not allow for manual, rapid retraction of the baffle plate as needed, thus preventing a quick increase in the gap between the baffle plate and the rice outlet. For example, CN209005807U discloses a rice milling machine precision adjustment device; CN217940268U discloses a rice milling machine rice output precision adjustment device. This type of rice output adjustment mechanism is suitable for rice milling machines with high processing capacity.

[0003] As people's living standards improve, their requirements for rice processing also increase. Freshly milled rice retains less nutrition and has a richer aroma, leading to a growing market for small-scale rice milling machines designed for immediate consumption. These machines process only a small amount of rice at a time (generally no more than one pound). However, their structural design means that some rice will remain at the baffle plate during processing. This residual rice is usually not processed during the initial processing and will be discharged during the next batch. While this has less impact on high-volume milling machines, it significantly affects the freshness of the rice processed by small-scale machines. Existing rice discharge adjustment mechanisms, although reducing pressure on the baffle plate by releasing a spring in the adjustment assembly to allow residual rice to be discharged after processing, are not only difficult to completely remove residual rice and inconvenient to use, but can also disrupt the user's adjusted settings. For very small rice milling machines designed for on-demand processing with small batch sizes, it's impractical to gradually adjust them to the correct position during subsequent processing. If a pull rod is directly installed on one side of the guide column, slidably connected to the rice output adjustment housing, to manually pull the rice baffle plate backward quickly, the pulling force on the baffle plate is concentrated on one side. Because these small rice milling machines are small, the spring force for adjusting the baffle plate pressure is also relatively small. In practice, this method has shown that the baffle plate is prone to tilting and getting stuck on the guide column, preventing it from returning to its original position. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a rice discharge adjustment mechanism and rice milling machine that can quickly discharge residual rice at the rice baffle without damaging the original gear position and facilitate the reset of the rice baffle, so as to improve the ease of use of rice milling machines, especially small rice milling machines that are milled on the spot.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a rice dispensing adjustment mechanism, including a rice dispensing shell, a rice baffle plate, a guide column, a spring and a gear adjustment component. The rice dispensing shell has a rice dispensing port on its front side plate. A guide cylinder with the same center as the rice baffle plate is fixed on one side of the rice baffle plate. A connecting plate is provided between the front side plate and the rear side plate of the rice dispensing shell.

[0006] The rice-blocking plate is arranged between the front side plate of the rice-discharging shell and the connecting plate, and cooperates with the rice-discharging port. The rice-blocking plate is slidably connected to the connecting plate along the axial direction of the rice-discharging port through the guide cylinder, so that it can slide towards or away from the rice-discharging port.

[0007] The guide post is coaxially arranged with the guide cylinder. One end of the guide post is inserted into and fixed inside the guide cylinder, and the other end extends outward through the rear side plate of the rice dispensing shell. The guide post and the rear side plate of the rice dispensing shell are slidably engaged.

[0008] The spring is located on the rear side of the rice-blocking plate, and its front end is connected to the rice-blocking plate. The spring is installed inside the guide cylinder and sleeved on the guide post.

[0009] The adjusting component cooperates with the rear end of the spring to adjust the compression length of the spring, thereby adjusting the rice discharge pressure of the rice-blocking plate through the spring.

[0010] Furthermore, the gear shifting assembly includes a shift fork, a gear shifting shaft, and a ratchet;

[0011] The fork is disposed between the connecting plate and the rear side plate of the rice dispensing housing. The fork is slidably disposed on the guide post so that it can slide along the guide post toward or away from the rice dispensing port. The fork cooperates with the rear end of the spring.

[0012] The adjusting shaft is arranged parallel to one side of the guide column, and the adjusting shaft is rotatably connected to the rice outlet shell.

[0013] The ratchet is fixed on the gear shift shaft and cooperates with the shift fork so that when it rotates with the gear shift shaft, the shift fork can slide along the guide post toward or away from the rice outlet, thereby adjusting the compression length of the spring through the shift fork.

[0014] Furthermore, the gear shifting shaft is positioned above the guide post.

[0015] Furthermore, a downward-sloping broken rice filter screen is provided below the rice outlet.

[0016] Furthermore, the rice-dispensing shell is made of sheet metal.

[0017] The rice milling machine adopts the rice output adjustment mechanism described above.

[0018] The beneficial effects of this utility model are:

[0019] The rice output adjustment mechanism and rice milling machine of this utility model will not damage the original rice output gear, making it more convenient to use. It also ensures that the guide column and rice baffle will not shake during use, thus ensuring the working stability of the rice milling machine.

[0020] The rice output adjustment mechanism and rice milling machine of this utility model are designed so that the guide cylinder and the rice baffle are concentrically arranged, the spring is arranged inside the guide cylinder and sleeved on the guide column, and the guide column is arranged coaxially with the guide cylinder. Therefore, when the rice baffle is pulled back by the guide column, the force on the rice baffle is more symmetrical relative to its center line, and it will not be tilted. The rice baffle is not easy to get stuck during the reset process and is easy to reset.

[0021] The rice output adjustment mechanism of this invention is particularly suitable for very small rice milling machines that are used for on-demand rice milling. Attached Figure Description

[0024] The figure shows: rice outlet shell 1, rice baffle plate 2, spring 3, guide column 4, gear adjustment assembly 5, guide cylinder 6, broken rice filter screen plate 7, front side plate 11, rear side plate 12, connecting plate 13, shift fork 51, gear adjustment shaft 52, ratchet 53, rice outlet 111, gear adjustment curved surface 531. Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] like Figure 1 , Figure 2As shown, the rice dispensing adjustment mechanism of this utility model includes a rice dispensing housing 1, a rice baffle plate 2, a guide post 4, a spring 3, and a gear adjustment assembly 5. The rice dispensing housing 1 is composed of four enclosing side plates, and a rice dispensing port 111 is provided on the front side plate 11 of the rice dispensing housing 1. In order to quickly discharge residual rice at the rice baffle plate, facilitate the reset of the rice baffle plate, and avoid damaging the original gear position, this utility model makes the following improvements: a guide cylinder 6 concentric with the rice baffle plate 2 is fixed on one side of the rice baffle plate 2, and the rice dispensing housing 1... A connecting plate 13 is provided between the front side plate 11 and the rear side plate 12; the rice baffle 2 is arranged between the front side plate and the connecting plate 13 of the rice dispensing shell 1 and cooperates with the rice dispensing port 111 to block the rice dispensing port 111. The rice baffle 2 is slidably connected to the connecting plate 13 along the axial direction of the rice dispensing port 111 through the guide cylinder 6 so that it can slide towards or away from the rice dispensing port 111; the spring 3 is arranged on the rear side of the rice baffle 2 (the direction facing the rear side plate of the rice dispensing shell is rear), and its front end is connected to the rice baffle 2. The spring 3 is installed in the guide cylinder 6 and sleeved on the guide post 4; the adjusting assembly 5 cooperates with the rear end of the spring 3 to adjust the compression length of the spring 3, thereby adjusting the rice dispensing pressure of the rice baffle 2 through the spring 3.

[0027] The guide cylinder 6 can be fixed to the rice baffle plate by welding, bolting, snap-fitting, or other methods. Of course, the guide cylinder can also be an integral structure with the rice baffle plate.

[0028] The rice dispensing adjustment mechanism of this utility model operates on the same principle as existing rice dispensing adjustment mechanisms in adjusting rice dispensing pressure: when it is necessary to adjust the rice dispensing pressure of the rice baffle 2, the compression length of the spring 3 is adjusted by adjusting the adjustment component 5, thereby changing the force exerted by the spring 3 on the rice baffle 2, and thus adjusting the rice dispensing pressure of the rice baffle 2. Specifically, as... Figure 2 As shown, when the adjusting component 5 compresses the spring 3 to shorten it, the force exerted by the spring 3 on the rice blocking plate 2 increases, and the rice dispensing pressure of the rice blocking plate 2 increases; when the adjusting component 5 releases the spring 3 to lengthen it, the force exerted by the spring 3 on the rice blocking plate 2 decreases, and the rice dispensing pressure of the rice blocking plate 2 decreases.

[0029] In this invention, one end of the guide post 4 is inserted and fixed inside the guide cylinder 6, and the other end extends outward through the rear side plate of the rice outlet housing 1. The guide post 4 is slidably connected to the rear side plate of the rice outlet housing 1, and the rice baffle 2 is slidably connected to the connecting plate 13 along the axial direction of the rice outlet 111 through the guide cylinder 6, which is concentric with it. Therefore, when the rice is processed, pulling the guide post 4 outward will compress the spring 3 and drive the rice baffle 2 to slide outward (away from the rice outlet), thereby rapidly increasing the gap between the rice baffle 2 and the rice outlet, allowing the rice remaining on the rice baffle 2 to fall out quickly. This not only allows for cleaner discharge of residual rice, but also eliminates the need to change the position of the adjustment component, does not damage the original rice outlet setting, and is more convenient to use. In order to enable the rice-blocking plate 2 to quickly retract via the guide post 4, this invention slidably connects one end of the guide post 4 to the rear side plate of the rice-discharging shell 1, and then constrains the other end of the guide post 4 with a connecting plate. This ensures that the guide post and the rice-blocking plate will not wobble during use, guaranteeing the working stability of the rice milling machine, making it particularly suitable for rice-discharging shells made of sheet metal. Furthermore, because the guide cylinder 6 and the rice-blocking plate 2 are concentrically arranged, and the spring 3 is arranged inside the guide cylinder 6 and sleeved on the guide post 4, and the guide post 4 is coaxially arranged with the guide cylinder 6, the force on the rice-blocking plate 2 is more symmetrical relative to its centerline during the retraction process via the guide post 4, preventing skewing. The rice-blocking plate 2 is less likely to get stuck during resetting and is easier to reset. When all the residual rice has fallen out, releasing the guide post 4 allows the rice-blocking plate 2 to slide smoothly towards the rice outlet under the restoring force of the spring 3 and automatically reset.

[0030] The gear shifting assembly 5 can adopt various existing gear shifting assemblies, such as a linear sliding gear shifting assembly that slides linearly along the axis of the guide post 4, or a rotary gear shifting assembly. Figure 2As shown, in this utility model, the gear adjusting assembly 5 is a horizontally rotating gear adjusting assembly, including a shift fork 51, a gear adjusting shaft 52, and a ratchet 53. The specific structure of the ratchet 53 can be found in patent applications CN217940268U or CN209005807U, and will not be described in detail here. The shift fork 51 is disposed between the connecting plate 13 and the rear side plate of the rice dispensing housing 1. The shift fork 51 is slidably disposed on the guide post 4, allowing it to slide along the guide post 4 towards or away from the rice dispensing port 111. The shift fork 51 cooperates with the rear end of the spring 3. The gear adjusting shaft 52 is arranged parallel to one side of the guide post 4, and the gear adjusting shaft 52 is rotatably connected to the rice dispensing housing 1. The ratchet 53 is sleeved and fixed on the adjusting shaft 52 and cooperates with the shift fork 51. When the ratchet 53 rotates with the adjusting shaft 52, the shift fork 51 moves along the guide post 4 towards or away from the rice outlet 111, thereby adjusting the compression length of the spring 3. When adjusting the rice dispensing pressure, rotating the adjusting shaft 52 counterclockwise or clockwise changes the cooperation position between the ratchet adjusting surface 531 and the shift fork 51, allowing the shift fork 51 to move along the guide post 4 towards or away from the rice outlet 111, thus compressing or releasing the spring 3 and adjusting the rice dispensing pressure of the rice baffle 2. Whether clockwise or counterclockwise rotation of the adjusting shaft 52 increases the rice dispensing pressure of the rice baffle 2 depends on the spiral upward direction of the ratchet adjusting surface 531, which will not be specifically elaborated here.

[0031] In the above structure, the gear shifting shaft 52 can be positioned above, to the left, to the right, or below the guide post 4. In this embodiment of the present invention, the gear shifting shaft 52 is positioned above (on the upper side) the guide post 4.

[0032] In this utility model, the gear adjustment component 5 also adopts the existing vertical rotary gear adjustment component, such as the patent application published with publication number CN211159912U.

[0033] like Figure 2 As shown, a downward-sloping broken rice filter sieve 7 is provided below the rice outlet 111 for filtering broken rice, rice bran, etc.

[0034] It should be noted that, in order to facilitate the turning of the gear adjustment shaft 52, a gear adjustment knob can be set on the gear adjustment shaft 52 as needed.

[0035] This utility model also provides a rice milling machine, especially a very small rice milling machine for on-demand rice milling, which adopts the above-mentioned rice output adjustment mechanism.
