Description

Technical Field

[0001] The utility model belongs to the technical field of rice milling machines, and in particular relates to a material discharging structure of a rice milling machine. Background Art

[0002] The vertical iron roller rice milling machine works by grinding grain into white rice through the rotation and friction of the iron rollers. It primarily consists of an emery roller, rice screen, rice cutter, discharge device, and transmission mechanism. The milling pressure is primarily controlled by a weight that lifts a tray via a lever, adjusting the size of the milling chamber outlet. After the brown rice flows into the milling chamber from the inlet, it is milled by the emery roller and rice screen. The rice bran outlet is connected to an external air source, where it enters the air duct.

[0003] At present, a Chinese patent with publication number CN217093619U and publication date of August 2, 2022 discloses a high-efficiency vertical rice milling machine, including a base and a rice milling machine body. The upper surface of the base is fixedly connected to a motor, and the inside of the rice milling machine body is vertically fixedly connected to a grinding cylinder, and the top of the grinding cylinder is fixedly connected to a top mesh plate. The lower surface of the top mesh plate is rotatably connected to a grinding roller, and the surface of the grinding roller is fixedly connected to spiral blades. The lower end of the left side wall of the rice milling machine body is penetrated and fixedly connected to a rice inlet, and the upper end of the right side wall of the rice milling machine body is penetrated and fixedly connected to a rice outlet.

[0004] The rice inlet of this high-efficiency vertical rice mill is set lower than the rice outlet. The spiral blades allow the rice to rise and finally be discharged through the rice outlet, which prolongs the rice milling time, makes the rice grains more fully milled, improves the milling efficiency, effectively avoids secondary milling, reduces the possibility of rice grains being crushed during over-milling, and ensures the appearance and quality of the rice.

[0005] The rice grains are discharged from the rice outlet. In order to maintain smooth rice discharge from the rice outlet, the inner wall of the rice outlet pipe needs to be cleaned regularly. At the same time, when rice grains are blocked in the rice outlet pipe, the rice outlet pipe needs to be unblocked. However, since the rice outlet pipe cannot be opened, cleaning and unblocking the rice outlet pipe is very inconvenient. Utility Model Content

[0006] The purpose of the utility model is to provide a discharge structure of a rice mill, which can facilitate the convenient opening of a rice discharge pipe.

[0007] The above technical objectives of the present utility model are achieved through the following technical solutions: a discharge structure of a rice milling machine, comprising a rice outlet opened on the upper side of a rice milling machine body, a rice outlet pipe connected to the rice outlet at one end, an operation port opened on the upper side of the rice outlet pipe, a flip cover for covering the operation port provided on the upper side of the rice outlet pipe, first connecting ears provided on both sides of the upper end of the flip cover, a first through hole provided on the first connecting ear, a connecting block located between the two first connecting ears provided on the upper end of the rice outlet pipe, connecting shafts passing through the first through hole provided on both sides of the connecting block, a reset torsion spring provided on the connecting shaft at one end connected to the connecting block and the other end connected to the first connecting ear, a connecting piece for detachably connecting the lower end of the flip cover to the lower end of the rice outlet pipe is provided between the flip cover and the rice outlet pipe.

[0008] The utility model is further configured as follows: the connecting piece includes second connecting ears arranged on both sides of the lower end of the flip cover, a second through hole opened on the second connecting ear, a third connecting ear arranged at the side of the rice outlet pipe and corresponding to the position of the second connecting ear, a third through hole opened on the third connecting ear, a positioning column arranged on the third connecting ear and passing through the third through hole and the second through hole, a positioning plate arranged at one end of the positioning column away from the second connecting ear, and a return spring sleeved on the positioning column and connected to the positioning plate at one end and the third connecting ear at the other end.

[0009] The utility model is further configured as follows: a welding plate welded to the side wall of the rice outlet pipe is provided on one side of the third connecting ear.

[0010] The utility model is further configured as follows: both sides of the flip cover are provided with clamping plates for fitting on the side walls of the rice outlet pipe.

[0011] The present invention is further configured as follows: a first observation window is provided at the lower end of the flip cover.

[0012] The present invention is further configured as follows: second observation windows are provided on both side walls of the rice outlet pipe.

[0013] In summary, the present invention has the following beneficial effects:

[0014] 1. When it is necessary to clean the inner wall of the rice outlet pipe or dredge the rice outlet pipe, the connector is disassembled, and then the flip cover is driven to flip upward under the elastic restoring force of the reset torsion spring. Then the flip cover can be removed from the operation port, and the operator can reach into the rice outlet pipe through the operation port to clean the inner wall of the rice outlet pipe or dredge the rice outlet pipe, and finally the rice outlet pipe can be opened conveniently;

[0015] 2. When the flip cover needs to be opened, the positioning post is simply pulled toward the side away from the second connecting ear. The return spring is stretched, and the positioning post is then pulled out of the second through hole. After the positioning post loses its positioning function, the flip cover can be flipped upward under the elastic restoring force of the return torsion spring.

[0016] When the flip cover needs to be closed, the flip cover is closed on the operating opening, with the second through hole aligned with the position of the third through hole, and then the positioning post is released. Under the elastic restoring force of the reset spring, the positioning post can pass through the third through hole and then be embedded in the second through hole. The position of the flip cover can be positioned by the positioning post, which is conducive to the stable closing of the flip cover on the operating opening;

[0017] 3. A welding plate provided on one side of the third connecting lug and welded to the side wall of the rice outlet pipe is used to facilitate stable fixation of the third connecting lug on the side wall of the rice outlet pipe;

[0018] 4. When the flip cover is closed on the operating port, the card plates provided on both sides of the flip cover can be attached to the side wall of the rice outlet pipe. At this time, the closing position of the flip cover can be limited by the card plates, which can ultimately facilitate the stable closing of the flip cover on the operating port.

[0019] 5. The first observation window provided at the lower end of the flip cover allows the operator to observe the rice discharge situation in the rice discharge pipe from the outside through the first observation window;

[0020] 6. The second observation windows are provided on both side walls of the rice discharging pipe, so that the operator can observe the rice discharging situation in the rice discharging pipe from the outside through the second observation windows. BRIEF DESCRIPTION OF THE DRAWINGS
