Description

[0001] BULK CARGO HOMOGENIZER

[0002] Field of invention

[0003] This patent refers to grain homogenizing equipment during the loading of silos and agricultural warehouses, applied in Agriculture, through the formation of successive mounds of 1 to 1.5 m, with homogeneous and automated distribution of grains of different apparent densities, of grain parts, of impurities, of foreign materials, thus avoiding both the segregation of these different materials and the compaction of grains at different densities, preventing the formation of preferential paths at the time of grain aeration.Reducing harmful effects such as grain self-combustion, activation of grain metabolism, fungi, insects and bacteria, and the formation of yellow grains, as well as reducing the entry of people into silos and warehouses to spread grains, also reducing electricity consumption in aeration processes, as well as the risk of workers being engulfed by the release of compacted grains, and traffic jams in cargo trucks due to waiting times caused by blockages in the flow of grains caused by compaction.

[0004] Fundamentals of the invention

[0005] As those involved in the agribusiness sector know, during the post-harvest phase of grain storage in silos and warehouses, silo loading is the most crucial step in the grain storage process. A poorly loaded silo can result in losses of 5 to 30% of the stored volume. Compacted silos cause problems during unloading because the grains don't flow through the discharge ports, leading to time-consuming and high-risk operations for workers to unblock them. Occupational accidents in silos are quite common in Brazil and worldwide.

[0006] Compaction leads to the formation of insect "hot spots" because moisture is concentrated in compacted regions, and the temperature of the grain mass rises, accelerating their reproductive process. Excessive moisture in grains also promotes the growth of fungi and bacteria and causes yellowing of the grains, particularly in rice. Compaction also blocks aeration, which involves fan operation to reduce grain temperature and promote an initial reduction in grain moisture.

[0007] Furthermore, a flow of grains in the silo or warehouse without homogeneous distribution leads to the separation of grains by different sizes, promoting densification and compaction, and also leads to the separation of broken grains, residues and foreign materials, which promote the reproduction of insects, fungi and bacteria.

[0008] Currently, there are the following conventional methods of distributing grains in silos and warehouses:

[0009] In the most traditional and manual process, operators enter the silos and warehouses to spread the grains with the help of hand tools, such as squeegees and rakes.

[0010] There are several grain spreading equipment options available on the national market for silos and warehouses. Searching commercial websites, we found the following grain spreading or distributing equipment available:

[0011] The grain distribution equipment commercially supplied by DGA Authentic Grãos, available at www.dgatech.com.br, features a central chute that receives the flow of grains poured into the silo or warehouse. This chute centralizes the flow to a motorized circular rotary distributor, which, through centrifugal force, causes the flow to the periphery of the distributor, where a series of oblique tubes regularly arranged along the outer diameter of the distributor, in a position transverse to the outer circle, spread the grain flow throughout the silo. The center of the circular distributor, in this specific model, features an inverted conical bottom to prevent grain accumulation in the center of the distributor.

[0028] Conventional solutions for grain distribution in silos and warehouses generally involve circular flows, generating centrifugal forces that separate grains and impurities of different sizes and densities, resulting in self-sorting that is detrimental to storage. Among the prior art patents cited are patents BR102013019881, BR202022007768U2, BR202017009699Y1, BR202020016726U2, KR102412535B,

[0029] BR202019016972U2, CN106664996A, CN113148703A, show grain distribution by rotation.

[0030] Other commercially available or patented solutions include distributors with central ducts that cause separation due to density differences, or cause blockages that require time-consuming intervention to unblock them, posing risks to operators. Examples of equipment with central ducts or extensive ducts with systems that may require intervention in the event of blockages include patents BR102022013586, BR202017009699Y1, US11472646B2, CN204999344U, and CA2128497C.

[0031] Some grain distributors are driven by gears or racks, which are rigid elements that pose a high risk of breakage and irreversible damage to the equipment. Patents BR102013019881, BR202022007768U2, BR202017009699Y1, BR202020016726U2, and CN113148703A reveal examples of equipment driven by rigid elements.

[0032] Currently available solutions feature a central shaft to allow equipment to rotate, connected to the structure by spokes, which cause the accumulation of impurities and foreign materials, and promote clogging and flow blockages.

[0033] Existing solutions do not allow for completely remote operation, as they are not monitored by cameras and sensors, requiring on-site inspection by the operator, which presents the risk of serious accidents.

[0034] Current conventional processes present the following drawbacks, disadvantages, and limitations: a. High-speed circular motion of the grains, with a tendency for self-sorting of grains by diameter classes, and separation of impurities due to centrifugal force, with a consequent increase in the proliferation of insects and pests; b. When present, central ducts that cause densification and compaction of the grains, which facilitates fermentation and blockage of the ducts, with increased risk of unblocking; c. Lack of remote monitoring, with increased risks and the need for human intervention; and d. Movement through rigid shafts with gears and racks, with a risk of breakage and irreversible loss of equipment.

[0035] “BULK LOAD HOMOGENIZER” was developed to overcome the inconveniences, disadvantages and limitations of the current processes for loading grain silos and warehouses, through an integrated solution with a grain spreading device, level sensors to perform the operation in piles of 1 to 1.5 m in height with automated completion of the operation, without high-speed circular movement that could generate centrifugal forces, belt drive, absence of a central axis, monitoring by video cameras with filming in visible and infrared light.

[0036] Current conventional processes present the following technical problems, which the process of this patent solves: i. Current grain spreaders often use spreaders with a circular motion capable of generating significant centrifugal forces, which cause the separation of grain sizes and the separation of straw and impurities, which promote the proliferation of insects and pests. This problem is solved by the present invention through the use of movement without generating centrifugal forces; ii. In many cases, the use of a central duct, which can clog and cause blockages and densification. This problem is solved in this patent through the use of large-diameter radial ducts; iii. In the vast majority of cases, the use of rigid transmission elements such as shafts with gears and racks, which can break, irreversibly damaging the equipment. This problem is solved in this invention through the use of a belt; iv.In some cases, the device is supported by the internal shaft, which contributes to clogging. This is resolved by the present invention with the support attached to the upper part and the lower part rotating by a belt and bearings, which connect the upper structure to the lower structure from the external part; v. Lack of remote monitoring, requiring on-site control and posing a safety risk to the operator. This is resolved in the present patent by the level sensor with remote shutdown, as well as by monitoring with video cameras with visible and infrared light; vi. Systems for closing the grain outlets of radial ducts that require individual adjustments, this is resolved by the present invention through a system of individual quick-closing butterfly valves in each spreading duct; and vii. Static electricity buildup due to the friction of the grains in the flow, which can cause sparks and trigger accidents such as dust explosions.This patent addresses this issue through a grounding system for pipes over 4 m in length, using steel cabling to assist with guying and provide grounding that dissipates static energy generated during grain passage. The research that led to this invention aimed to enable the homogeneous loading of silos or bulk grain warehouses, safely and automatically. Development of the equipment began approximately 15 years ago. During this time, successes and failures were made, which were subsequently corrected through studies, testing, and customer feedback.

[0037] In previous prototypes, the ducts became clogged due to the accumulation of impurities in the shaft fixing crossbars as well as in the adjustment of the grain outlet covers.

[0038] The next steps were to determine the movement of the duct distribution container, as well as define its diameters and dimensions, and the control and monitoring of the flow.

[0067] In this way, when the motor (8) rotates at a pre-defined pace, the belt (7) causes the lower structure (2) to rotate at this pre-defined pace, changing the position of the grains spreading through the ducts (2-A).

[0068] Optionally, as shown in figures 11 and 12, it is possible to use the regulator tube (10), equipped with a metal tube (10-a), with a through hole on its side; equipped with a regulator (10-b), metal, in the shape of a disc whose diameter is proportional to the tube (10-a), with an axis fixed in the central part of the face of the disc, in which the ends of the axis are positioned in the holes of the tube (10-a) allowing a tilting movement; equipped with a clamp (10-c) that surrounds the tube (10-a); equipped with a casing (10-d), metal, that surrounds a servomotor; and equipped with a support (10-e), metallic, in the shape of a “C” with a rectangular profile and with a hole in its face, fixed to the side of the tube (10-a) and to the casing (10-d), in which the regulator shaft (10-b) passes through the hole in the support (10-e) and is connected to the servo motor inside the casing (10-d).

[0069] A plurality of regulator tubes (10) can be installed, one in each of the cylindrical ducts (2-Al) of the lower assembly (2). To install the regulator tube (10), the butterfly valves (2-A-2), manual actuators (2-A-3), springs (2-A-4) and spring supports (2-A-5) must be removed from the ducts (2-A). After removing these components, the end with the clamp (10-c) of the tube (10-a) is positioned around the cylindrical duct (2-Al). The clamp (10-c) is then tightened to secure the regulator tube to the lower assembly (2).

[0070] The servomotor positioned inside the housing (10-d) can be connected and controlled via an application whose interface (13) has a silo selector (13-a); a regulator selector (13-b); and a flow selector (13-c).

[0071] Optionally, as shown in figures 13 and 14, the grain homogenizer assembly can use a central regulator (11), which is equipped with a cardan shaft (11-b) with two crosspieces, preferably with an 8% displacement, with one of its ends fixed to the apex of the Chinese hat (5-D) and its other end fixed to the motor (11-a); and motor (11-a), preferably a 12vdc stepper motor, or similar.

[0072] Alternatively to the regulator (10), the grain homogenizer assembly can use the flow regulator (12).

[0073] According to figures 15 to 18, the flow regulator (12) is equipped with a parallel arm (12-a), metallic, in the shape of two arches with an extension that extends perpendicularly at one of its ends, arranged in parallel; equipped with a support (12-b), metallic, rectangular in shape with rounded ends, which connects the end of the arch of the parallel arm (12-a) to the motor (12-e); equipped with shoes (12-c), metallic, fixed in its lower part to the duct (2-Al) and connected to the extensions of the parallel arm (12-a) in such a way as to allow its rotation; equipped with an arm (12-d), metallic, rectangular in shape with rounded ends, positioned between the arches of the parallel arm (12-a), connecting the opposite end to the extension of the parallel arm (12-a) to the cover (12-f); equipped with a motor (12-e), preferably electric, connected to the supports (12-b);equipped with a lid (12-f), with geometry equivalent to the interior part of the duct (2-Al), connected to the arm (12-d) in such a way as to allow its rotation; and equipped with a supporter (12-g), in the shape of an axle, fixed in such a way as to penetrate the interior of the duct (2-Al) offering support to the upper part of the lid (12-f).;

[0074] According to figures 15, 18 and 19, the arm (12-d) is fixed between the extensions of the parallel arm (12-a) and fixed to the shoe (12-c) through a pin that allows its rotation.

[0075] Alternatively, the support (12-f) may be in the form of an elongated pin, provided that its length is adequate to support the cover (12-f). The flow regulator (12) is positioned in the ducts (2-Al) after the manual actuators (2-A-3) of the butterfly valves (2-A-2). The flow regulator (12), in turn, can be activated through an application, where it will be possible to fully or partially open each duct (2-Al) individually according to the operator's needs.

[0076] Examples of embodiments of the invention

[0077] The process of homogeneous distribution of grains in a warehouse or silo by the grain homogenizer that is the subject of this patent takes place through the following sequence of steps:

[0078] I. The equipment is positioned at the top of the silo or warehouse, in the position where the bulk grain flow is received;

[0079] II. The operator records on the control panel (3) the rotation time for positioning the ducts and forming the grain piles, and the loading time for each pile flow, according to the incoming flow. As a non-limiting reference, the rotation time can be 30 seconds, equivalent to a rotation angle of 15°, and the loading time in a fixed position can be 2 minutes;

[0080] III. The operator starts loading the grains, which flow into the center of the upper structure (1);

[0081] IV. The grain flow occurs by directing it towards the pan of the upper structure (1), hitting the gutter (6), which positions the flow towards the center of the lower structure (2);

[0082] V. The flow through the central cone at the bottom of the lower structure (2) directs the flow of grains evenly to the spreading ducts (2- A);

[0083] VI. The flow divided by the ducts spreads throughout the silo or warehouse in homogeneous mounds 1 to 1.5 m high;

[0084] VII. The level control automatically stops the flow when the setup is reached, and informs you through an audible alarm;

[0085] VIII. The lower structure (2) moves in a circular motion at a pre-set angle, for example 15 degrees, according to the rotation time set on the control panel (3);

[0086] IX. The lower structure stops, and the operation of loading a new set of grain piles is repeated along the silo, until it is finally filled; and

[0087] X. The operation is carried out remotely, monitored by cameras in visible light and infrared.

[0088] According to figures 13 and 14, the central regulator (11) can be activated through the application interface (13) or the control panel (3), where a signal is sent to the motor (11-b), activating it. The motor (11-b), when activated, rotates the cardan shaft (11-b) that transfers the rotation to the Chinese hat (5-D), regulating its height by screwing / unscrewing the threaded bar (5-C). In this way, the gap between the disc (5-B) and the Chinese hat (5-D) is changed, regulating the flow of grain to the set of ducts (2-A).

[0089] The application will register the storage units, which can be a single silo or multiple silos. According to figures 20 and 21, the application interface (13) has a silo selector (13-a), which allows a user to select different homogenizers installed in different silos. Once the silo is selected, the interface (13) displays the regulator selector (13-b), which allows the user to select the regulator they wish to adjust, including the flow regulators (12) installed individually in each duct (2-Al), the central regulator (11) or regulator tube (10), or all regulators. Once the regulators are selected, the opening rate can be selected through the flow selector (13-c), where, in this embodiment, values ​​of 0%, 25%, 50%, 75%, and 100% opening are presented.

[0090] In one embodiment, the homogenizers have 4 to 12 ducts (12-Al), preferably 150 to 200 mm in diameter. For optimal operation at the beginning of silo loading, the user activates the homogenizer equipment on the control panel (3). Then, the user opens the shorter and medium ducts (2-Al) through the app. After the volume exceeds half of the silo, the operator opens the larger ducts (2-Al), allowing perfect filling of the silo's lateral spaces.
