Description

Technical Field

[0001] This utility model belongs to the field of rice milling machine technology, and in particular relates to a rice milling machine with an adjustable discharge port. Background Technology

[0002] A rice milling machine is an agricultural machine used to process paddy rice into finished rice. Its core function is to remove the outer shell (husk), pericarp, seed coat and part of the endosperm of paddy rice through processes such as dehulling, whitening and separation, and finally obtain white rice (or brown rice, depending on the processing precision) that meets the standards for food consumption. It is a key piece of equipment in the paddy rice processing industry chain and is widely used in small workshops, grain processing plants and other scenarios.

[0003] In existing technologies, traditional rice milling machines typically have a fixed-height discharge port. When used in small workshops, common containers include rice buckets and plastic basins, whose size and height are random. If the discharge port height is fixed, when the container height is lower than the discharge port, the rice grains are prone to splashing due to excessive drop during the material's descent. When used in grain processing plants, rice milling machines need to form a continuous operation process with downstream equipment (white rice grading screens, destoners, packaging machines, etc.). The inlet height of downstream equipment varies significantly depending on the model and function. Therefore, a rice milling machine with an adjustable discharge port is needed, which can raise and lower the guide cavity through an adjustable structure to accommodate different receiving containers and improve compatibility with downstream equipment on the production line. Utility Model Content

[0004] The purpose of this utility model is to provide a rice milling machine with an adjustable discharge port, which can raise and lower the guide cavity through an adjustable structure to adapt to different receiving containers and improve compatibility with downstream equipment in the production line, thereby solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A rice milling machine with an adjustable discharge port includes a rice milling machine body; a feeding funnel is installed on the surface of the rice milling machine body; a finished rice discharge port is fixedly installed on the surface of the rice milling machine body by bolts; a rice bran discharge port is fixedly connected to the surface of the rice milling machine body; a guide cavity is provided on the front of the finished rice discharge port; the side of the finished rice discharge port contacts the guide cavity; four rectangular plates are fixedly connected to the back of the guide cavity; two connecting rods are provided on the back of the guide cavity; the connecting rods are fixedly connected to the rectangular plates; limit sliders are fixedly connected to both the left and right sides of the rice bran discharge port; the connecting rods pass through the limit sliders and are slidably connected to the limit sliders; an insertion hole is opened on the side of the limit slider; the insertion hole communicates with a through hole on the surface of the limit slider; a fastening threaded sleeve is fixedly connected to the surface of the limit slider; a bolt is threadedly connected to the inner cavity of the fastening threaded sleeve; one end of the bolt passes through the fastening threaded sleeve and the insertion hole; and one end of the bolt contacts the connecting rod.

[0006] Preferably, a rubber baffle is fixedly installed at the bottom of the rice bran outlet, and a fixing plate is fixedly connected to the surface of the rice milling machine body.

[0007] Preferably, a limiting rod is fixedly connected to the surface of the fixing plate, and a connecting plate is fixedly connected to the top of the flow guiding cavity.

[0008] Preferably, the limiting rod passes through the connecting plate, and the limiting rod is slidably connected to the connecting plate.

[0009] Preferably, the fixing plate is an L-shaped right-angle plate, and the rubber curtain plays a certain role in blocking.

[0010] The beneficial effects of this utility model are: 1. This utility model involves removing the bolt from the fastening threaded sleeve, then moving the position of the guide cavity up and down to limit the sliding of the connecting rod within the through hole of the limiting slider. After adjusting the guide cavity to the appropriate position, the bolt is inserted into the fastening threaded sleeve and tightened, so that one end of the bolt abuts against the connecting rod in the through hole of the limiting slider, thereby applying friction to the connecting rod and locking it. The rice milling machine is then started, and the paddy rice to be processed is poured into the rice milling machine through the feeding funnel. The processed finished rice is discharged through the finished rice outlet and the guide cavity. This allows the guide cavity to be raised and lowered by adjusting the structure to adapt to different receiving containers and improve compatibility with downstream equipment in the production line. 2. This utility model uses the rubber baffle, fixed plate, limiting rod and connecting plate in combination. When the guide cavity moves up and down, the guide cavity drives the connecting plate fixedly connected to its surface to slide at the upper limit of the limiting rod on the surface of the fixed plate, so that the guide cavity is more stable when moving up and down. When the rice milling machine body discharges the finished rice through the finished rice outlet and the guide cavity, the rubber baffle provides a certain degree of protection for the rice grains.

Detailed Implementation

[0013] In the following description, embodiments of the rice milling machine with an adjustable discharge port of the present invention will be described with reference to the accompanying drawings.

[0014] Figure 1-4 This invention discloses an embodiment of a rice milling machine with an adjustable discharge port, comprising a rice milling machine body 1. A feeding funnel 2 is mounted on the surface of the rice milling machine body 1. The rice milling machine body 1 includes a hulling mechanism, a rice milling chamber, and a separation and screening mechanism. A finished rice discharge port 3 is bolted to the surface of the rice milling machine body 1. A rice bran discharge port 4 is fixedly connected to the surface of the rice milling machine body 1. A rubber baffle 12 is fixedly mounted at the bottom of the rice bran discharge port 4. The rice milling machine is connected to the rubber baffle 12, a fixing plate 13, a limiting rod 14, and a... The connecting plate 15 works in conjunction with the flow guide cavity 5. When the flow guide cavity 5 moves up and down, the connecting plate 15, which is fixedly connected to its surface, slides at the upper limit on the limiting rod 14 on the surface of the fixed plate 13, making the flow guide cavity 5 more stable when moving up and down. When the rice milling machine body 1 discharges the finished rice through the finished rice outlet 3 and the flow guide cavity 5, the rubber baffle 12 provides a certain degree of protection for the rice grains. The fixed plate 13, which is an L-shaped right-angle plate, is fixedly connected to the surface of the rice milling machine body 1. The curtain 12 provides some blocking function. A limiting rod 14 is fixedly connected to the surface of the fixing plate 13, passing through the connecting plate 15 and slidably connected to it. The top of the guide cavity 5 is fixedly connected to the connecting plate 15. The front of the finished rice outlet 3 is provided with the guide cavity 5, and the side of the finished rice outlet 3 contacts the guide cavity 5. Four rectangular plates 6 are fixedly connected to the back of the guide cavity 5, and two connecting rods 7 are provided on the back of the guide cavity 5. The connecting rods 7 connect to the rectangular plates 6. Plate 6 is fixedly connected. Limiting sliders 8 are fixedly connected to both sides of the rice bran outlet 4. Connecting rod 7 passes through the limiting slider 8 and is slidably connected to the limiting slider 8. Insertion hole 9 is opened on the side of the limiting slider 8. Insertion hole 9 communicates with the through hole on the surface of the limiting slider 8. Fastening threaded sleeve 10 is fixedly connected to the surface of the limiting slider 8. Bolt 11 is threadedly connected to the inner cavity of the fastening threaded sleeve 10. One end of bolt 11 passes through the fastening threaded sleeve 10 and the insertion hole 9. One end of bolt 11 is in contact with connecting rod 7.

[0015] Working principle: When using this utility model, the user removes the bolt 11 from the fastening threaded sleeve 10, then moves the position of the guide cavity 5 up and down, causing the guide cavity 5 to drive the connecting rod 7 to slide within the through hole of the limiting slider 8. After adjusting the guide cavity 5 to a suitable position, the bolt 11 is inserted into the fastening threaded sleeve 10 and tightened, so that one end of the bolt 11 passes through the fastening threaded sleeve 10 and the insertion hole 9, causing one end of the bolt 11 to abut against the connecting rod 7 in the through hole of the limiting slider 8. This causes one end of the bolt 11 to apply friction to the connecting rod 7, thereby causing the bolt 11 to push the connecting rod... 7. Locking: At this time, turn on the rice milling machine body 1 and pour the paddy rice to be processed into the rice milling machine body 1 through the feed funnel 2. The paddy rice is first dehulled in the dehulling mechanism of the rice milling machine body 1, and then enters the rice milling chamber of the rice milling machine body 1 for fine rice processing. Finally, the separation and screening mechanism of the rice milling machine body 1 will separate and discharge the rice bran and other impurities through the rice bran outlet 4. The processed finished fine rice will be discharged through the finished rice outlet 3 and the guide cavity 5. This achieves the purpose of adjusting the height of the guide cavity through the adjustable structure to adapt to different receiving containers and improve the compatibility with downstream equipment of the production line.

[0016] In summary: This rice milling machine with an adjustable discharge port achieves its purpose by removing the bolt 11 from the fastening threaded sleeve 10, then moving the position of the guide cavity 5 up and down, allowing the connecting rod 7 to slide within the through hole of the limiting slider 8. After adjusting the guide cavity 5 to a suitable position, the bolt 11 is inserted into the fastening threaded sleeve 10 and tightened, so that one end of the bolt 11 abuts against the connecting rod 7 within the through hole of the limiting slider 8, applying friction to the connecting rod 7 and locking it in place. The rice milling machine body 1 is then turned on, and the paddy rice is poured into the rice milling machine body 1 through the feeding funnel 2. The finished rice is discharged through the finished rice discharge port 3 and the guide cavity 5. This allows the guide cavity to be raised and lowered via an adjustable structure, adapting to different receiving containers and improving compatibility with downstream equipment in the production line.
