Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, specifically a cleaning device for rice processing. Background Technology

[0002] Rice husk processing is the process of removing the husk (chaff) and bran (fragrance) from cleaned rice. A rice grain consists of the husk, bran, embryo, and endosperm. The purpose of rice processing is to separate the endosperm from the other parts with minimal breakage, producing rice with better eating quality.

[0003] Existing rice peeling and washing equipment results in a high rate of rice breakage and incomplete separation of the husk during peeling. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Firstly, it can continuously perform rice peeling, washing, and unloading operations, thereby improving rice processing efficiency.

[0016] Secondly, the extrusion chamber formed between the spiral conveyor blades and the extrusion plates allows for multiple extrusions of the rice grains, achieving thorough peeling and cleaning, thus improving cleaning efficiency. During extrusion, the elastic extension and retraction function of the elastic sleeve provides space for the horizontal movement of the spiral conveyor blades, preventing the rice grains from being crushed and improving the quality of the rice.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0024] Example

[0025] Please see Figure 1-3 This utility model provides a cleaning device for rice processing, including a box 1, a spiral conveying blade 2 is provided inside the box 1, a drive motor 3 is fixedly connected to one side of the box 1, the output shaft of the drive motor 3 is fixedly connected to the central shaft 201 on the spiral conveying blade 2 through an elastic sleeve 301, and a plurality of extrusion plates 202 are equidistantly arranged inside the box 1.

[0026] A water outlet 101 is provided on the other side of the box body 1, and a feed hopper 102 is provided on the top of the box body 1;

[0027] A storage trough 103 is provided at the bottom of the other side of the box 1.

[0028] Specifically: First, water is injected into the tank 1 so that the liquid level is the same height as the outlet 101. Then, water and rice are continuously fed into the tank 1 along the feed hopper 102. The drive motor 3 drives the spiral conveyor blades 2 to rotate, thereby realizing the horizontal transportation of rice. At the same time, the spiral conveyor blades 2 and the extrusion plate 202 form an extrusion chamber, which can extrude rice multiple times to achieve peeling and cleaning. The cleaning effect is thorough and the cleaning efficiency is improved.

[0029] During the compression process, the elastic extension and retraction function of the elastic sleeve 301 provides space for the horizontal movement of the spiral conveyor blade 2, avoiding crushing the rice grains and improving the quality of the rice.

[0030] The washed rice husks are discharged through the outlet 101, and the peeled rice settles in the storage tank 103.

[0031] A connecting sleeve 203 is fixedly connected to the central shaft 201, and an L-shaped rod 204 is fixedly connected to the bottom of the connecting sleeve 203. Multiple levers 205 are set on the L-shaped rod 204 by means of a coil spring.

[0032] Multiple levers 205 are fixedly connected to a pull plate 206, a sealing plate 207 is elastically connected to the bottom of the storage tank 103, and a baffle 208 is fixedly connected to the top of the sealing plate 207.

[0033] Specifically: while the spiral conveyor blades 2 are conveying and cleaning the rice, the connecting sleeve 203 drives multiple levers 205 to rotate synchronously, thereby agitating the settled rice and realizing the secondary rinsing and cleaning of the rice in the storage tank 103, further improving the cleaning quality.

[0034] Among them, multiple levers 205 can drive the pull plate 206 to rotate synchronously. The circumferential movement of the pull plate 206 can intermittently drive the baffle 208 and the sealing plate 207 to achieve intermittent opening and closing actions, thereby intermittently discharging the washed rice from the storage tank 103, realizing the sustainability of rice peeling, washing and discharge.

[0035] The coil springs provide space and reset force for the lever 205 to rotate around the L-shaped rod 204, and the elastic strength of the multiple coil springs is much greater than the elastic resistance of the sealing plate 207 in the storage tank 103, ensuring that the pull plate 206 can drive the sealing plate 207 to achieve intermittent opening and closing actions.

[0036] The outlet 101 is higher than the central axis 201.

[0037] The elastic sleeve 301 includes an outer rod and an inner rod. One end of the outer rod is fixedly connected to the output shaft of the drive motor 3. A spring is provided inside the outer rod. The inner rod is embedded in the inner cavity of the outer rod and abuts against the spring. The end of the inner rod is fixedly connected to the central shaft 201.

[0038] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
