Description

Technical Field

[0001] This utility model relates to the field of grain machinery and equipment technology, and in particular to a material distribution structure for undersize material in a grain cleaning machine. Background Technology

[0002] A flour purifier is a type of grain processing machinery. It separates pure and relatively pure endosperm particles from the material ground by a flour mill. It consists of a screen body, equipped with air ducts and air chambers. The screen body is supported by two pairs of rubber springs and driven by an eccentric or inertial force transmission mechanism to perform a throwing motion. Airflow passes upwards from below the screen body, through the screen surface, and enters the small air chambers at the top of the screen body. The airflow in each air chamber can be adjusted. The combined effect of vibration, the screen, and the airflow loosens the material entering the purifier and stratifies it according to specific gravity, particle shape, surface properties, and aerodynamic characteristics. Light bran is absorbed, and the endosperm with bran is output as the oversize material; the pure and relatively pure endosperm particles are returned to the flour mill as the undersize material for further grinding into high-grade or superior flour.

[0003] Existing powder cleaning machines do not achieve thorough material uniformity after feeding, resulting in uneven material distribution and inconsistent thickness. Thicker areas of accumulated material are not thoroughly cleaned, while thinner areas are easily blown away by airflow, causing airflow turbulence and affecting material grading and cleaning efficiency.

[0004] To address this issue, the inventors designed a material distribution structure at the feeding position. Utility Model Content

[0005] The purpose of this invention is to provide a material distribution structure for a powder cleaning machine that enables uniform feeding adjustment, precise air volume control, easy observation and maintenance, and improved material distribution accuracy.

[0006] To achieve the above-mentioned objectives, the present invention provides a material distribution structure for a powder cleaning machine undersize material, which employs the following technical solution:

[0007] A material distribution structure for undersize material in a powder cleaning machine includes:

[0008] rack body;

[0009] A chassis is installed on top of the rack body, with an air chamber located below the chassis and an air duct above the air chamber. An air box is also connected to one side of the air duct.

[0010] A screen body is installed inside the casing, and a feed inlet is located above the screen body facing the screen plate. This feed inlet is formed in the casing and communicates with the interior of the casing; and

[0011] The feeding and distributing assembly includes a rotating plate at the end of the feed inlet. Below the rotating plate is an inclined distributing plate with a distributing opening. A collection bin is located on one side of the distributing opening, exposed outside the machine casing and capable of being disassembled. With the collection bin and inclined distributing plate, when material falls from the feed inlet onto the inclined distributing plate, large-sized gravel and impurities are screened out and rolled into the collection bin for collection, improving the overall distributing accuracy of the machine.

[0012] A further improvement of the material distribution structure for a powder cleaning machine lies in the following: an airflow regulating device is installed on the air box, and an airflow regulating plate is installed inside the air box. The airflow regulating device is connected to the machine casing. The airflow regulating device includes an airflow scale on one side, a rotating shaft fixed to the airflow regulating plate, a connecting rod fixedly connected to the rotating shaft at one end, and a handle assembly at the end of the connecting rod. The rotating shaft is rotatably connected to the air box. A partition plate is fixed inside the air box, dividing it into left and right chambers. There are two airflow regulating plates, located in the left and right chambers respectively. The angle between the two airflow regulating plates is controlled by rotating the handle assembly. The operator rotates the airflow regulating plate through the handle assembly of the air box, and adjusts the airflow to the appropriate value using the scale plate. The airflow carries away light impurities as it passes through the screen.

[0013] A further improvement of the material distribution structure for the screened material of the powder cleaning machine is that the collection bin is made of transparent material, and insert blocks are provided on both sides of the collection bin. The machine casing is provided with slots that cooperate with the insert blocks. The collection bin is connected to the machine casing through the insert blocks and slots. The machine casing can be disassembled and cleaned periodically, which facilitates maintenance and replacement.

[0014] A further improvement of the material distribution structure of the powder cleaning machine is that a transparent observation window is provided in the air duct corresponding to the position of the machine box.

[0015] A further improvement of the material distribution structure of the powder cleaning machine is that the number of screens is two sets, and they can be disassembled relative to the machine casing.

[0016] A further improvement of the material distribution structure of the powder cleaning machine is that a uniform material plate is inclinedly arranged below the distribution plate. The uniform material plate has several fish-scale-shaped protrusions arranged in an array. The uniform material plate is located below the distribution plate and forms an angle with respect to the distribution plate. The powdered material is evenly dispersed by the fish-scale protrusions, resulting in uniform feeding.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. The material is set up with a collection bin and an inclined distribution plate. When the material falls from the feed inlet to the inclined distribution plate, large-sized gravel impurities will be screened out by the inclined distribution plate and rolled into the collection bin for collection, thus improving the material distribution accuracy of the entire machine.

[0019] 2. The operator rotates the air volume adjustment plate through the handle kit of the bellows, and adjusts the air volume to the appropriate value in conjunction with the dial. When the airflow passes through the screen, it carries away light impurities.

[0020] 3. A uniform material plate is inclined below the material plate. The uniform material plate has several fish scale-shaped protrusions arranged in an array. The uniform material plate is located below the material distribution plate and forms an angle with respect to the material distribution plate. The powdered material is evenly dispersed by the fish scale protrusions, and the feeding is uniform. Attached Figure Description

It should be understood that these embodiments are only for illustrating the present invention and not for limiting the scope of the present invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] like Figure 1-4 As shown, a material distribution structure for undersize material in a powder cleaning machine includes:

[0029] The frame body is 100;

[0030] A chassis 110 is provided above the rack body 100, with an air chamber 120 below the chassis and an air duct 130 above the air chamber. An air box 140 is also connected to one side of the air duct.

[0031] A screen body 200 is installed inside the casing, and a feed inlet 300 is provided above the screen body facing the screen plate. This feed inlet is formed in the casing 110 and communicates with the interior of the casing; and

[0032] The feeding and distributing assembly 400 includes a rotating plate at the end of the feed inlet 300. Below the rotating plate is an inclined distributing plate 410 with a distributing opening 411 formed on its main body. A collection bin 420 is located on one side of the distributing opening, exposed outside the machine casing and capable of being disassembled. With the collection bin and inclined distributing plate, when material falls from the feed inlet onto the inclined distributing plate, large-sized gravel and impurities are screened out by the inclined distributing plate and rolled into the collection bin for collection, improving the overall distributing accuracy of the machine.

[0033] Specifically, the air box 140 is equipped with an airflow regulating device, and an airflow regulating plate is installed inside the air box. The airflow regulating device is connected to the casing. The airflow regulating device includes an airflow scale 141 on one side, a rotating shaft fixed to the airflow regulating plate, a connecting rod fixedly connected to the rotating shaft at one end, and a handle assembly 142 at the end of the connecting rod. The rotating shaft is rotatably connected to the air box. A partition plate is fixed inside the air box, dividing it into left and right chambers. There are two airflow regulating plates, located in the left and right chambers respectively. Rotating the handle assembly controls the angle between the two airflow regulating plates. The operator rotates the airflow regulating plate using the handle assembly of the air box, and adjusts the airflow to the appropriate value using the scale plate. The airflow carries away light impurities as it passes through the screen.

[0034] Specifically, the collection hopper is made of transparent material, with inserts on both sides and slots on the chassis to mate with these inserts. The collection hopper is connected to the chassis via the inserts and slots. The collection hopper can be disassembled periodically for cleaning, maintenance, and replacement.

[0035] Specifically, a transparent observation window 131 is provided in the air duct corresponding to the position of the chassis.

[0036] Specifically, there are two sets of 200 sieve bodies, which can be disassembled relative to the chassis.

[0037] Specifically, a uniform material plate 430 is inclinedly arranged below the material distribution plate. The uniform material plate has several fish-scale-shaped protrusions 431 arranged in an array. The uniform material plate is located below the material distribution plate and forms an angle with respect to the material distribution plate. The powdered material is evenly dispersed by the fish-scale protrusions, resulting in uniform feeding.

[0038] The specific working principle of this utility model is as follows:

[0039] Material enters from the feed inlet of the machine casing, allowing it to fall evenly onto the inclined distribution plate below. Large-sized gravel and impurities are screened out by the inclined distribution plate, flowing along the inclined surface and rolling down to the collection bin. As the material passes through the distribution port, the uniform distribution plate below further disperses it, ensuring that the material is evenly covered on the screens of the two sets of screens. At the same time, the operator rotates the air volume adjustment plate using the handle kit of the bellows, and adjusts the air volume to the appropriate value using the dial. As the airflow passes through the screen, it carries away light impurities. During this process, the airflow status is observed through the transparent observation window of the air duct.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0041] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
