[0032] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0033] Please refer to the attached drawing, which is a structural schematic diagram of a preferred embodiment of an air injection and exhaust system and a rice milling and polishing device provided by the utility model.

[0034] An air jet and air exhaust system is used to jet and exhaust air from a main body of a rice milling and polishing device, and the air jet and air exhaust system comprises:

[0035] A feeding assembly 1 is installed on the top of the main body and is used for feeding materials;

[0036] An air jet fan 2, the air jet fan 2 is connected to the feed assembly 1, and the air jet fan 2 is used to blow air or water mist into the main body;

[0037] The residue collection chamber 7 and the vacuum assembly 3 are provided at the lower part of the main body. The residue collection chamber 7 is used to collect the residue generated in the main body. The outer wall of the residue collection chamber 7 is provided with a discharge port. The vacuum assembly 3 is connected with the discharge port. The vacuum assembly 3 is used to extract the residue in the residue collection chamber 7.

[0038] The utility model uses the air jet fan 2 to spray air into the main body, promotes the residue to pass through the screen assembly in the main body, and accelerates the discharge of the residue, opens a discharge port on the outer wall of the residue collection chamber 7, and communicates with the discharge port through the air extraction assembly 3, uses the air extraction assembly 3 to extract the residue in the residue collection chamber 7 to perform the bran discharge process, and can effectively improve the efficiency of bran discharge. At the same time, the arrangement of the air jet fan 2 and the air extraction assembly 3 can also accelerate the air flow rate in the main body, which is conducive to the timely discharge of heat in the main body, and assists in forming a suitable temperature inside the main body, thereby improving the processing quality of the material.

[0039] It should be noted that the main body also includes a grinding chamber 4 and a screen assembly. The grinding chamber 4 is arranged in the main body and is connected to the bottom of the material leveling seat 102. The grinding chamber 4 is used to grind and grind the material, and the ground and polished material is discharged from the discharge port 6; the screen assembly is located in the grinding chamber 4, and a bran collecting chamber is formed between the screen assembly and the inner wall of the main body. The screen assembly is used to filter the residue generated in the grinding chamber 4 and introduce it into the bran collecting chamber. The residue in the bran collecting chamber enters the residue collecting chamber 7 under the action of wind and gravity; a rotary knife assembly 5 is arranged in the grinding chamber 4, and multiple groups of rotary knife assemblies 5 are arranged on the main shaft 8 in the main body along the axial direction of the main shaft 8. The rotary knife assembly includes a plurality of rotary blades arranged on the main shaft 8 in a circumferential annular array along the main shaft 8. Vents are opened on the rotary blades. The vents on the rotary blades can not only reduce the weight of the rotary blades, but also improve the air circulation in the main body, which is beneficial to the temperature control and dryness in the main body. In addition, a spray nozzle is provided at the outlet of the air jet fan to spray water mist.

[0040] Preferably, please refer to Figure 1 and 4 As shown, the feed assembly 1 includes a feed seat 101 and a material-distributing seat 102 which are connected up and down. The feed seat 101 is used for feeding materials, and the material-distributing seat 102 is used for dispersing materials. The air jet fan 2 is connected to the material-distributing seat 102 .

[0041] Specifically, the material dividing plates 106 are symmetrically arranged along the central axis of the material mixing seat 102. The material dividing plates 106 on both sides are inclined and connected at the tops, dividing the interior of the material mixing seat 102 into two material discharge channels. The side wall of the material mixing seat 102 is provided with an air inlet located between the two material discharge channels, and the air inlet pipe 104 of the jet fan 2 is connected to the air inlet.

[0042] It can be understood that the dividing plates 106 on both sides are built to form a structure with a conical cross-section, and divide the interior of the material distributing seat 102 into two material discharge channels, so that the material can fall into the main body; and the material distributing seat 102 also provides a connecting position for the jet fan 2, so that the jet fan 2 can spray air from the top of the main body.

[0043] Optionally, a heating plate assembly for heating the material is disposed in the material-splitting seat 102 , and the heating plate assembly is disposed on the inner side of the material dividing plates 106 on both sides facing away from the material-discharging channel.

[0044] Specifically, the heating plate assembly includes a support frame 105, which is arranged inside the dividing plates 106 on both sides. The gap between the side wall of the support frame 105 and the dividing plates 106 forms an installation portion, and a heating plate is arranged in the installation portion. The heating plate is used to heat the materials in the two feeding channels.

[0045] It can be understood that when the material rolls down from the surface of the dividing plate 106, the dividing plate 106 can be heated by the heating plate, and then the material can be heated to ensure that the temperature of the material is appropriate and improve the efficiency and quality of grinding and polishing; at the same time, the heating plate heats the inside of the material leveling seat 102 to prevent the material from sticking to the material leveling seat 102 in winter, affecting the fluidity and uniformity of the material, and can ensure that the temperature of the air blown into the material leveling seat 102 by the external jet fan 2 is appropriate, avoiding over-cooled air from blowing into the main body to affect the processed material and reduce moisture inside the main body.

[0046] In a preferred embodiment, please refer to Figure 5 The exhaust assembly 3 includes a brake dragon, an exhaust fan and a pulse dust collector which are connected in sequence.

[0047] It is understandable that the exhaust component 3 needs to remove dust from the exhaust air while extracting the residue, and the cyclone dust collector and pulse dust collector in conjunction with the exhaust fan can effectively improve the degree of dust removal, ensure the cleanliness of the exhaust air, and reduce pollution to the workshop air.

[0048] In another preferred embodiment, please refer to Figure 6 The exhaust assembly 3 includes a diaphragm, a pulse dust collector and an exhaust fan which are connected in sequence.

[0049] It can be understood that the exhaust component 3 in this embodiment can also realize the function of collecting residues and removing dust, and similarly, the position of the exhaust fan is placed at the rear to reduce the excessive impact of air with excessive impurity concentration on the exhaust fan, which is beneficial to extend the service life of the product and reduce the frequency of cleaning and maintenance.

[0050] It should be noted that, in the above two embodiments of the air extraction assembly 3, a wind cap can be provided at the rear end to shield and protect the exhaust port at the rear end.

[0051] Preferably, please refer to Figure 3 As shown, the discharge port of the residue collection chamber 7 includes a first discharge port 702 and a second discharge port 703 , and both the first discharge port 702 and the second discharge port 703 are connected to the air extraction component 3 .

[0052] It can be understood that the double discharge ports connected to the double suction components 3 can effectively improve the efficiency of bran discharge.

[0053] Preferably, please refer to Figure 3 As shown, a rotatable cleaning assembly is provided in the residue collection chamber 7, and the cleaning assembly includes a rotating member 701 driven to rotate by a driving unit, and blades are provided in an annular array on the outer wall of the rotating member 701. The rotating member 701 is used to clean the residue in the residue collection chamber 7 to the discharge port.

[0054] It is understandable that if the residue is simply extracted by the external suction component 3, the residue processed by the grinding chamber 4 is easily blocked in the screen hole, causing large current fluctuations and affecting the final yield. Therefore, a rotatable cleaning component is set in the residue collection chamber 7 to clean the residue to the discharge port, thereby accelerating the efficiency of bran discharge.

[0055] According to another aspect of the utility model, a rice milling and polishing device is provided, which comprises the above-mentioned air injection and exhaust system.

[0056] The rice milling and polishing equipment of the utility model also has the above-mentioned beneficial effects.

[0057] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0058] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. The above is only the preferred implementation method of the utility model. It should be pointed out that due to the limitations of textual expression and the objective existence of infinite specific structures, ordinary technicians in this technical field can make several improvements, modifications or changes without departing from the principles of the utility model, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the concept and technical solution of the utility model to other occasions without improvement, should be regarded as the protection of the utility model.
