DETAILED DESCRIPTION

[0030] 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.

[0031] Please refer to the attached drawing, which is a structural schematic diagram of a preferred embodiment of a uniform feeding device and a rice milling and polishing machine provided by the utility model.

[0032] A uniform feeding device includes a feeding assembly 100, wherein the feeding assembly 100 includes:

[0033] A feed seat 101 for feeding raw grain materials, a plug switch mechanism 102 is arranged in the feed channel of the feed seat 101, the plug switch mechanism 102 includes a plug assembly 105 movably arranged in the feed channel of the feed seat 101, and the plug assembly 105 is used to adjust the opening size of the feed channel of the feed seat 101 to adjust the feed flow rate of the raw grain materials;

[0034] The material-scraping seat 103 is arranged below the material-feeding seat 101 and is in communication with the material-feeding seat 101. The material-scraping seat 103 is used for dispersing materials. A heating plate assembly for heating materials is arranged inside the material-scraping seat 103.

[0035] Here, the "feed seat 101" refers to a structure for feeding raw grain materials. In some embodiments, the feed seat 101 is a hollow cylindrical structure, specifically a cubic cylindrical structure or a cylindrical cylindrical structure.

[0036] Here, the "material mixing seat 103" refers to the material feeding and distributing structure connected to the material feeding seat 101. In some embodiments, the material mixing seat 103 is a frame structure that is narrow at the top and wide at the bottom.

[0037] The utility model sets a plug switch mechanism 102 in the feed seat 101, and adjusts the opening size of the feed channel of the feed seat 101 through the plug assembly 105 of the plug switch mechanism 102 to adjust the feed flow of the raw grain material, so that the control of the feed material flow is very convenient and direct. At the same time, a material leveling seat 103 is connected and arranged below the feed seat 101. The material leveling seat 103 can not only disperse the material and realize dispersed feeding, but the heating plate assembly in the material leveling seat 103 can also heat the material to avoid the material from agglomerating; the heating plate assembly also heats and insulates the material leveling seat 103 as a whole, avoids the material leveling seat 103 causing material adhesion in winter, reduces the impact on the material fluidity, and ensures uniform material feeding.

[0038] Preferably, please refer to Figure 1-5As shown, the plug switch mechanism 102 also includes a mounting box, which is arranged on the side wall of the feed seat 101. The plug assembly 105 includes plugs spaced apart from each other, each plug passing through the side wall of the feed seat 101. A pushing assembly is arranged in the mounting box, and the pushing assembly is used to drive each plug relative to the feed channel of the feed seat 101 to open and close.

[0039] It can be understood that the horizontally movable plug plate can open or close the feed channel of the feed seat 101, and at the same time, pushing the component plug plate can realize the size of the feed channel opening, thereby realizing the control of the material feed flow rate, so as to adapt to different working conditions and ensure the stability of processing quality.

[0040] In a preferred embodiment, the plug plate assembly 105 includes a first plug plate and a second plug plate spaced apart from each other in the upper and lower parts, and the pushing assembly drives the first plug plate and the second plug plate to respectively open and close the feed channel relative to the feed seat 101 .

[0041] It is understandable that, by only providing two first plug plates and a second plug plate spaced apart from each other, the closing function of the feed seat 101 in an emergency and the function of regulating the opening of the feed seat 101 in normal circumstances can be achieved through different plug plates.

[0042] Of course, the present invention does not exclude the solution of providing more layers of plug boards, which can reduce the frequency of maintenance and replacement of the plug boards.

[0043] In this preferred embodiment, the pushing component includes a mini cylinder 107 and a linear motor 108. The mini cylinder 107 is used to push the first plug plate to open and close the feed channel of the feed seat 101, and the linear motor 108 is used to push the second plug plate to open and close the feed channel of the feed seat 101 to adjust the size of the feed channel opening of the feed seat 101.

[0044] It is understandable that the material is fed when the first plug plate and the second plug plate are fully opened, and can be fully closed in an emergency to ensure that no material enters the main body in an emergency to cause dangerous consequences.

[0045] It should be noted that the linear motor 108 can accurately control the horizontal displacement of the second plug plate to achieve the control of the opening size of the feed channel of the feed seat 101; the first plug plate controlled by the mini cylinder 107 can be opened and closed quickly, which is used to quickly close the feed seat 101 in an emergency situation to achieve an emergency stop.

[0046] Optionally, see Figure 2 As shown, the pushing assembly further includes a distance sensor 106, and the distance sensor 106 is used to measure the displacement distance of the second plugboard.

[0047] It is understandable that the distance sensor 106 can assist the linear motor 108 in controlling the displacement distance of the second plug plate, so as to accurately open the feed channel and control the flow rate of the material.

[0048] Preferably, please refer to Figure 3 and Figure 4 As shown, the material distribution plates 109 are symmetrically arranged along the central axis of the material distribution seat 103. The material distribution plates 109 on both sides are inclined and connected at the top to separate the interior of the material distribution seat 103 into two material discharge channels. The heating plate assembly is arranged on the inner side of the material distribution plates 109 on both sides with their backs facing the material discharge channels.

[0049] It can be understood that the dividing plates 109 on both sides are constructed to form a structure with a conical cross-section, and divide the interior of the material distributor 103 into two material discharge channels, so that the material falls into the grinding chambers on both sides of the grinding chamber of the main body.

[0050] Preferably, please refer to Figure 3 and Figure 4 As shown, the heating plate assembly includes a support frame 110, which is arranged inside the dividing plates 109 on both sides. The gap between the side wall of the support frame 110 and the dividing plates 109 forms a mounting portion, and a heating plate 111 is arranged in the mounting portion. The heating plate 111 is used to heat the materials in the two feeding channels.

[0051] It can be understood that when the material rolls down from the surface of the dividing plate 109, the dividing plate 109 can be heated by the heating plate 111, 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 111 heats the inside of the material sizing seat 103 to prevent the material from sticking to the material sizing seat 103 in winter, affecting the fluidity and uniformity of the material, and ensuring that the temperature of the air blown into the material sizing seat 103 by the external jet fan is appropriate, avoiding over-cooled air from blowing into the main body to affect the processed material, and reducing moisture inside the main body.

[0052] Preferably, please refer to Figure 1 As shown, the side wall of the material distributing seat 103 located at the material discharge channel is provided with an observation window, and a transparent plate is provided at the observation window.

[0053] It is understandable that the observation window can facilitate workers to observe the situation in the material discharge channel of the material screed seat 103, and to find special situations in time. The transparent plate can be made of transparent plates such as glass and fiberglass, and the transparent plate can be installed in the observation window by bolts, or by torsion springs or rotating shafts, so that the transparent plate can be opened.

[0054] Preferably, please refer to Figure 1 and Figure 3As shown, the bottom of the support frame 110 is open, and the side wall of the material-splitting seat 103 is connected to the air inlet pipe 104 of the external fan, and the air inlet pipe 104 is used to supply air to the bottom of the support frame 110 .

[0055] It is understandable that the air inlet pipe 104 supplies air to the bottom of the support frame 110, which can adjust the temperature inside the material scrambling seat 103 and the material to ensure that the temperature of the material is appropriate, and can also take away the heat or moisture in the material scrambling seat 103.

[0056] According to another aspect of the utility model, a rice milling and polishing machine is provided, which comprises the above-mentioned uniform feeding device.

[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.
