Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, and in particular to a feeder for rice processing. Background Technology

[0002] In the rice processing industry, the feeding stage is the initial stage of production, and the performance and function of its equipment directly affect the quality and efficiency of subsequent processing.

[0003] Traditional rice processing feeders primarily focus on transporting paddy rice from storage areas to processing equipment, with a relatively simple structure and function. In actual production, paddy rice raw materials often contain a large amount of lighter impurities such as rice husks. Traditional feeders, relying solely on simple sieve filtration, struggle to effectively remove these easily floating impurities, which are similar in size to the paddy rice. In subsequent processing steps, residual rice husks not only affect the purity and quality of the finished rice but may also cause uneven friction and compression with the paddy rice inside the processing equipment due to differences in hardness. This leads to accelerated equipment wear, shortened equipment lifespan, and increased maintenance costs and downtime.

[0004] To address the above problems, we propose a feeder for rice processing. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a feeder for rice processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A rice processing feeder includes a separating cylinder with supports fixedly installed on both sides. A decontamination mechanism is provided on the left side of the separating cylinder, and an auxiliary dehulling mechanism is provided at the bottom of the separating cylinder. The decontamination mechanism includes an air inlet duct, a back plate is screwed to the left end of the air inlet duct, a fan is fixedly installed on the back plate, the fan outlet extends to the right side of the back plate, a rectangular bend is fixedly installed inside the air inlet duct, the lower end of the rectangular bend extends to the lower side of the air inlet duct, a bearing is fixedly installed at the lower end of the rectangular bend, a turntable is rotatably installed in the middle of the bearing, and a plurality of blades are fixedly installed circumferentially on the side wall of the turntable.

[0007] Furthermore, a flared cone cover is fixedly installed at the upper end of the rectangular bend.

[0008] By adopting the above technical solution, the flared cone can increase the air intake of the rectangular bend, thereby making the airflow at the lower end of the rectangular bend larger, which in turn drives the fan blades to rotate the turntable.

[0009] Furthermore, the auxiliary shelling mechanism includes a heating plate, a plurality of first springs are fixedly installed at the bottom of the heating plate, and a mounting side plate is fixedly connected to the lower end of the first springs. The mounting side plate is fixedly connected to the inner side of the bracket.

[0010] Furthermore, the heating plate is internally fitted with heating wires and is inclined, with several protrusions fixedly connected to the upper side of the heating plate.

[0011] By adopting the above technical solution, when the heating wire is started, the heating plate has a preheating effect on the screened rice. When the rice slides down the heating plate, it rubs against several protrusions, making it easier to thresh in subsequent processing.

[0012] Furthermore, a side support is fixedly installed on the left side of the heating plate, a second spring is fixedly installed on the side of the side support, and a hard rubber block is fixedly installed on the left side of the second spring, the hard rubber block being located on the side of the turntable.

[0013] Furthermore, a dustproof net is fixedly installed at the air inlet on the left side of the fan.

[0014] By adopting the above technical solution, the dustproof net is installed to prevent dust from entering the air inlet duct.

[0015] Furthermore, an air inlet is provided on the left side of the separation cylinder, and the air inlet cylinder is screwed onto the left side of the air inlet.

[0016] Furthermore, an air outlet is provided on the right side of the separation cylinder, a guide plate is fixedly installed on the lower side of the air outlet, and a collection trough is placed on the lower side of the guide plate.

[0017] By adopting the above technical solution, under the action of air blowing, light impurities such as rice husks in rice can be discharged from the air outlet to the right and finally slide onto the guide plate, where they fall back into the collection trough for collection.

[0018] Furthermore, a controller is fixedly installed on the outer wall of the bracket.

[0019] Furthermore, a rice-adding cone is fixedly installed on the upper side of the separating cylinder.

[0020] By adopting the above technical solution, the controller is used to control the operating status of the equipment.

[0021] Compared with related technologies, the rice feeder proposed in this utility model has the following beneficial effects: In this utility model, a rice processing feeder, through a decontamination mechanism, injects airflow into the air inlet duct when the fan is activated. The airflow then enters the separation duct, creating a blowing effect towards the right-side port. Light impurities such as rice husks in the rice are discharged to the right from the air outlet and finally slide onto the guide plate. Guided by the guide plate, they fall back into the collection trough for collection, effectively separating the light impurities from the rice. In addition, a portion of the airflow in the air inlet duct enters the rectangular bend and exits from the lower side of the bend, driving the fan blades to rotate. When the fan blades rotate, they provide vibration driving force for the auxiliary hulling structure. The structure is compact, and the decontamination mechanism, while providing decontamination, also drives the auxiliary hulling mechanism below to perform auxiliary hulling work, improving the efficiency of rice processing and enhancing its practicality.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-6A rice processing feeder includes a separating cylinder 1, with brackets 3 fixedly installed on both sides of the separating cylinder 1, a decontamination mechanism 5 on the left side of the separating cylinder 1, and an auxiliary dehulling mechanism 6 at the bottom of the separating cylinder 1. The decontamination mechanism 5 includes an air inlet duct 51, with a back plate 52 screwed to the left end of the air inlet duct 51. A fan 53 is fixedly installed on the back plate 52, with the air outlet of the fan 53 extending to the right side of the back plate 52. A rectangular bend 55 is fixedly installed inside the air inlet duct 51, with the lower end of the rectangular bend 55 extending to the lower side of the air inlet duct 51. A bearing seat 57 is fixedly installed at the lower end of the rectangular bend 55, and a turntable 58 is rotatably installed in the middle of the bearing seat 57. Several fan blades 59 are fixedly installed circumferentially on the side wall of the turntable 58.

[0026] In this embodiment, a dustproof net 54 is fixedly installed at the air inlet on the left side of the fan 53, and an air inlet 4 is opened on the left side of the separator 1. The air inlet 51 is screwed onto the left side of the air inlet 4.

[0027] With the above structure, the air inlet duct 51 can be removed from the air inlet 4, which facilitates later inspection and maintenance.

[0028] In this embodiment, an air outlet 7 is provided on the right side of the separation cylinder 1, a guide plate 8 is fixedly installed on the lower side of the air outlet 7, and a collection trough 9 is placed on the lower side of the guide plate 8.

[0029] Through the above structure, the guide plate 8 provides a guiding function for the impurities discharged from the air outlet 7. Finally, the impurities slide onto the guide plate 8 and then slide into the collection tank 9 for collection.

[0030] In this embodiment, a controller 10 is fixedly installed on the outer wall of the support 3, and a rice adding cone 2 is fixedly installed on the upper side of the separation cylinder 1.

[0031] Through the above structure, the controller 10 is used to control the operating status of each electrical component.

[0032] In this embodiment, a flared cone cover 56 is fixedly installed at the upper end of the rectangular bend 55.

[0033] With the above structure, the flared cone shroud 56 can increase the air intake at the upper end of the rectangular bend 55, thereby increasing the air output at the lower end of the rectangular bend 55, which is used to drive the fan blades 59 to rotate the turntable 58.

[0034] In this embodiment, the auxiliary shelling mechanism 6 includes a heating plate 63. Several first springs 62 are fixedly installed at the bottom of the heating plate 63. The lower end of the first springs 62 is fixedly connected to a mounting side plate 61. The mounting side plate 61 is fixedly connected to the inner side of the bracket 3. The heating plate 63 is embedded with heating wires and is inclined. Several protrusions 64 are fixedly connected to the upper side of the heating plate 63. A side support column 65 is fixedly installed on the left side of the heating plate 63. A second spring 66 is fixedly installed on the side of the side support column 65. A hard rubber block 67 is fixedly installed on the left side of the second spring 66. The hard rubber block 67 is located on the side of the turntable 58.

[0035] With the above structure, when the fan blade 59 rotates, it will indirectly impact the hard rubber block 67. Then, the second spring 66 adaptively bends and deforms, allowing the fan blade 59 to rotate smoothly through the hard rubber block 67. Subsequently, the second spring 66 drives the hard rubber block 67 to reset. Under the continuous impact of the fan blade 59, the heating plate 63 vibrates. Under the vibration, the rice grains that slide onto the heating plate 63 fully rub against the protrusions 64. Under the dual effects of preheating and friction, it is easier to thresh the grains in subsequent processing, improving processing efficiency. The setting of the first spring 62 reduces the vibration attenuation of the heating plate 63, allowing the heating plate 63 to maintain a high-efficiency vibration state.

[0036] In this invention, when using the rice processing feeder, the operator first pours the paddy rice into the separating cylinder 1 through the paddy rice adding cone 2. Then, the equipment is started via the controller 10 on the outer wall of the support 3, activating the fan 53 and the heating wires in the heating plate 63. After the fan 53 starts, the airflow enters the air inlet 51 from its left side, filtered by the dust filter 54, and then flows directly into the separating cylinder 1, creating a rightward blowing effect. Because lightweight impurities such as rice husks have low density and light weight, they are pushed by the airflow and discharged from the right-side outlet 7 of the separating cylinder 1. After being guided by the guide plate 8, they slide into the collection trough 9 for collection, completing the separation of lightweight impurities from the paddy rice. Simultaneously, another portion of the airflow enters the rectangular bend 55. Under the action of the flared cone 56, the air intake of the rectangular bend 55 increases, and the airflow discharged from the lower port increases. The strong airflow pushes the fan blades 59 on the side wall of the turntable 58, causing the turntable 58 to begin rotating. As the turntable 58 rotates, the fan blades 59 intermittently impact the hard rubber block 67. Upon impact, the second spring 66 bends and deforms under pressure, allowing the fan blades 59 to pass smoothly. Subsequently, the second spring 66 drives the hard rubber block 67 to reset. Under the continuous impact of the fan blades 59, the heating plate 63 connected to the hard rubber block 67 vibrates. The first spring 62 reduces the vibration attenuation of the heating plate 63, maintaining it in a highly efficient vibration state. The heating wires inside the heating plate 63 simultaneously heat it. When the screened rice falls from the separating cylinder 1 onto the inclined heating plate 63, the rice slides down the heating plate 63 under its own weight and vibration. During this process, the rice rubs against the protrusions 64 on the heating plate 63, absorbing heat from the heating plate 63 to complete preheating. Under the dual effects of preheating and friction, the rice husk loosens, creating favorable conditions for the subsequent threshing process and greatly improving processing efficiency.
