Description

Technical Field

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

[0002] Paddy refers to the grains of rice without the husk removed. Botanically, it belongs to the subspecies of Oryza in the subgenus Oryza of the genus Oryza in the family Poaceae. Paddy processing is the process of converting paddy into rice through a series of steps, mainly including cleaning, hulling, and milling. Currently, when separating the husk from paddy, cloth bags or other containers are used to cover the outlet of the hulling machine to collect the husk.

[0003] However, currently, there is a lack of effective collection and treatment measures for the dust generated during the rice husk separation process. Structures such as cloth bags do not have good dust prevention effects, which can easily lead to dust pollution in the working environment and endanger the health of workers. Furthermore, the separated rice husks are usually piled up in a loose state, which is bulky and not convenient for centralized transportation and subsequent resource utilization. For example, when used as raw materials for feed, biomass energy, etc., they require a lot of storage and transportation space. Utility Model Content

[0004] The purpose of this utility model is to provide a rice husk separation and recycling device for rice processing, so as to solve the problems mentioned in the background art, such as the dust generated during the rice husk separation process posing a health hazard to workers and the large volume of rice husks making them inconvenient for centralized transportation.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A rice processing husk separation and recycling device includes a rice dehulling machine, a recycling bin, and a conveying pipe. A dust suction component is installed above the rear side of the conveying pipe, and a squeezing component is installed inside the recycling bin.

[0007] The dust collection assembly includes a barrier net, an installation frame is provided above the barrier net, and a dust collection fan is provided inside the installation frame;

[0008] The extrusion assembly includes a push plate and an extrusion plate, and a pull plate is slidably disposed on the bottom inner side of the recycling bin.

[0009] In a preferred embodiment of this utility model, an internal threaded sleeve is rotatably provided on the outer side of the rice hulling machine's hulling port, and an external thread is provided in front of the conveying pipe, with the internal threaded sleeve and the external thread being threadedly connected.

[0010] In a preferred embodiment of this utility model, a connecting pipe is provided below the rear side of the conveying pipe, and the connecting pipe is connected to and communicates with the front side above the recycling bin.

[0011] In a preferred embodiment of this utility model, a spiral blade is rotatably arranged inside the conveying pipe, and a motor is arranged behind the conveying pipe, with the motor drive shaft connected to the spiral blade.

[0012] In a preferred embodiment of this utility model, a first electric push rod is provided in front of the recycling bin, and the telescopic end of the first electric push rod is connected to a push plate.

[0013] In a preferred embodiment of this utility model, a second electric push rod is provided on the rear side above the recycling bin, and the telescopic end of the second electric push rod is connected to a squeezing plate.

[0014] In a preferred embodiment of this utility model, a baffle is slidably provided behind the recycling bin, a connection port is provided at the bottom of the baffle, and a connecting bolt is provided behind the pull plate, with the connection port being detached and installed on the connecting bolt.

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0027] Please refer to Figures 1-5This utility model discloses a rice husk separation and recycling device for rice processing, comprising a rice husk dehulling machine 1, a recycling box 11, and a conveying pipe 12. The rice husk dehulling machine 1 is an existing rice husk dehulling machine, or a suitable rice husk separation machine such as a rice milling machine, used to dehull rice and achieve rice separation. The recycling box 11 and the conveying pipe 12 are mounting structures used to install other structures. An internal threaded sleeve 13 is rotatably provided on the outer side of the dehulling port of the rice husk dehulling machine 1, and an external thread 14 is provided in front of the conveying pipe 12. The internal threaded sleeve 13 and the external thread 14 are threadedly connected. The device consists of two structures. The outer structure of the inner threaded sleeve 13 is installed on the outside of the hulling port of the rice hulling machine 1 by welding or other means. The hulling port of the rice hulling machine 1 is the outlet for discharging rice husks. The inner threaded sleeve 13 is then locked inside and rotated. By rotating the inner threaded sleeve 13, the inner threaded sleeve 13 is connected to the outer thread 14, which allows the conveying pipe 12 to be fixedly installed at the hulling port of the rice hulling machine 1. Even if it is inconvenient to install the inner threaded sleeve 13, it can be left uninstalled. The recycling operation can also be completed by connecting the front of the conveying pipe 12 to the outside of the hulling port of the rice hulling machine 1.

[0028] The conveying pipe 12 is equipped with a rotating spiral blade 2. A motor 21 is located behind the conveying pipe 12. The drive shaft of the motor 21 is connected to the spiral blade 2. When the rice husks are discharged from the hulling port, the motor 21 drives the spiral blade 2 to rotate, thereby conveying the rice husks backward. A dust collection component is located above the rear side of the conveying pipe 12. The dust collection component includes a baffle net 22. A mounting frame 23 is located above the baffle net 22. A dust collection fan 24 is located inside the mounting frame 23. The dust collection part of the dust collection fan 24 is located inside the mounting frame 23. A dust collection bag is located at the dust outlet of the dust collection fan 24. The dust collection fan 24 absorbs a large amount of dust in the rice husks, thereby reducing the amount of dust when the rice husks are removed, effectively reducing the amount of dust inhaled by workers. The absorbed dust is collected in the dust collection bag for subsequent processing.

[0029] A pull plate 4 is slidably installed on the bottom inner side of the recycling bin 11. A connecting pipe 3 is installed below the rear side of the conveying pipe 12. The connecting pipe 3 is fixedly connected to and communicates with the front upper side of the recycling bin 11. That is, the rice husks conveyed in the conveying pipe 12 enter the recycling bin 11 through the connecting pipe 3 for collection. The recycling bin 11 is equipped with a squeezing assembly, which includes a push plate 31 and a squeezing plate 33. A first electric push rod 32 is installed at the front of the recycling bin 11. The telescopic end of the first electric push rod 32 is connected to the push plate 31. A second electric push rod 34 is installed at the rear upper side of the recycling bin 11. The telescopic end of the second electric push rod 34 is connected to the squeezing plate 33. When the amount of rice husks in the recycling bin 11 reaches a certain amount, the separation and conveying of rice husks are stopped. Then, the first electric push rod 32 pushes the push plate 31 to push the rice husks onto the pull plate 4. Then, the second electric push rod 34 pushes the squeezing plate 33 to squeeze the rice husks, thereby greatly reducing the volume of the rice husks and facilitating subsequent transportation and other operations.

[0030] A baffle 41 is slidably installed behind the recycling bin 11. A connection port 43 is provided at the bottom of the baffle 41. A connecting bolt 42 is provided behind the pull plate 4. The connection port 43 is attached and detached from the connecting bolt 42. When the baffle 41 and the pull plate 4 are both installed, the connecting bolt 42 is inserted into the connection port 43. At this time, the pull plate 4 cannot move. A rotating part 44 is rotatably installed behind the second electric push rod 34. A limit rod 45 is slidably installed on one side of the rotating part 44. By rotating the rotating part 44 at the bottom, the rotating part 44 is positioned above the baffle 41, and the limit rod 45 is pressed down to the front of the baffle 41. At this time, the rotating part 44 cannot be moved to the top of the baffle 41, thus fixing the position of the baffle 41. Conversely, the fixing is released, the baffle 41 can be opened, and the pull plate 4 can be pulled out. The squeezed rice husks are all under the pull plate 4, so that the pull plate 4 can pull out the rice husks.

[0031] The working principle of this utility model is as follows: The outer structure of the inner threaded sleeve 13 is installed on the outside of the hulling port of the rice hulling machine 1 by welding or other means. By rotating the inner threaded sleeve 13, the inner threaded sleeve 13 is connected to the outer thread 14, thereby fixing the conveying pipe 12 at the hulling port of the rice hulling machine 1. When the rice husks are discharged from the hulling port, the motor 21 drives the spiral blades 2 to rotate, thereby conveying the rice husks backward. The dust suction fan 24 absorbs a large amount of dust in the rice husks, thereby reducing the amount of dust inhaled by workers when the rice husks are removed. The rice husks conveyed in the conveying pipe 12 enter the recycling box 11 through the connecting pipe 3 for collection. When the amount of rice husks in the recycling box 11 reaches a certain level, the separation and conveying of the rice husks are stopped. Then, the first electric push rod 32 pushes the push plate 31 to push the rice husks onto the pull plate 4. The second electric push rod 34 then pushes the extrusion plate 33 to extrude the rice husks, thereby greatly reducing the volume of the rice husks and facilitating subsequent transportation and other operations. The extrusion plate 4 is opened by the baffle 41 and pulled out. The extruded rice husks are all on the pull plate 4, so that the pull plate 4 can pull out the rice husks.

[0032] Although embodiments of the present invention have been shown and described, those skilled in the art will understand 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 claims and their equivalents.
