Description

[Detailed description of the invention] Loading equipment and method for unloading materials Background of the invention 1. Field of invention The present invention allows grain, cement, and other dry storage materials to be stored in storage containers, domes, etc. or other horizontal containers. Than Specifically, the present invention includes a rotating scooping arm that sucks the material to be removed toward a central outlet. Disposal of material used for self-supporting domes or shell-shaped storage containers Regarding the output system.

2. Conventional technology Storing materials such as grains, cement, dry materials and other items in spread condition This brings with it a number of problems, and these problems are especially important when it comes to food and fuel, on which each country's economy depends. and affecting the availability of materials for construction. These issues include storage conditions; This ranges from special handling requirements when transporting materials. material is controlled requires a unique storage environment and unique handling requirements during loading and unloading at the storage location. The most difficult problems typically arise when methods of handling are needed.

Such materials include cement and similar materials that must be stored in a dry atmosphere. There are sowing items. Such materials require complete enclosure for protection from components. Due to the requirements, convenient access for evacuation is typically limited. movable Use a scooping shovel and packet directly to remove the material from the roof. Although it is possible to lift trucks and wagons, such equipment and methods It is labor intensive and requires significant capital investment for the construction of equipment and specialized buildings. do. As a result, storage and handling costs are reduced by simplifying the structure of the storage area. The industry trend is to focus on mitigating strikes.

For example, free-standing dome structures combine economical construction with the advantages of complete enclosure. It is a combination. U.S. Pat. No. 3,456,818 describes The dome structure used is described. The material is removed from the dome through the top opening. is loaded into the dome wall and rotates the auger, which horizontally wraps around the dome wall. Distribute grain outward by advancing the grain outward toward the target. This ogre , rotates at the top of the grain along its longitudinal axis and rotates around the central support column. 3606 to redistribute the grain across the top surface of the grain. The structure is such that it can be done. The double rotation of this auger is It serves to keep the auger in a "floating" state. The weight of this auger is The necessary components have been carefully selected to enhance this floating capability.

Unloading requires rotating the auger around its longitudinal axis (, central This is done by rotating the support column. There is an outlet on the floor below the support surface. This outlet allows material to fall from the interior of the dome due to gravity flow. It is equipped with an underfloor auger that functions as a conveyor to convey the material when it is being transported.

Once the grain has reached its natural flow ramp towards the central outlet, create the auger. move the remaining grain toward its center. Eventually, the rotating auger will When rotating horizontally near the surface, it is possible to advance the entire contents of the dome to the outlet. come.

Dome storage structures with conveyance systems were invented about 25 years ago, but have not been commercialized. was not very successful. This system also has physical properties similar to those of grains. Since it is considered to be used only for salvaged materials with high quality, the applied to other demanding storage such as dry goods and other dry goods. do not have. These latter materials naturally clump together due to the weight of the stored top layer. , becomes a rigid mass. This rigid mass is difficult to crush and the stored material It works by blocking the flow to the outlet due to gravity. The auger assembly is Since the structure is floating on top of the surface, it has no effect on the desired behavior of the material below the surface. It has no significant effect.

In view of the numerous problems associated with dome storage systems described above, it is difficult to move the stored material. Access is generally provided through side doors or openings formed in the base of the dome. Provided by. These doors can be opened and the front loader can load the material. Utilize conventional loading techniques using conveying scoop packets or similar devices enable. Unfortunately, highly compressed items such as cement Even if the support material underneath is discharged, it will not be easily soaked. Practically speaking, front loader creates a hollowed-out cavity of considerable size in a base layer of rigid material; There is a risk that the gap will collapse without warning and cause serious consequences.

US Patent No. 5.098.247 and European Patent Application No. 91100120.4 The inventor's earlier patents, such as those represented, include continuous horizontal An improvement in the use of a rotating auger to move the material into position and complete the discharge. A cargo unloading device is disclosed. Because the center of mass is constantly displaced from the vertical support column , as a result of the increased moment arm required to rotate the extended auger. Significant problems arise with the use of the mechanism. Typical design standards require that this auger be The output rated value of the rotating drive motor occurs when the auger is in a nearly horizontal direction. , it is necessary to select one to suit the maximum output demand. selectively with this , a larger gearbox or transmission device may provide the greater power required. You can do it like this. However, large power requirements and/or gearing may reduce the This results in a significant increase in overall costs.

The increased load required due to the larger moment arm reduces the compression to be expelled. This is even more pronounced due to the resistance force exerted by the removed material. Auger tilt angle While the moment arm increases with increasing degree, due to the weight of the supported material, As a result, the degree of compression of the material also increases with the increase in the tilting angle of the auger. It is interesting that these problems complement each other. Therefore, the auger is approximately horizontal while rotating. By the time the position is reached, the worst situation occurs. Specifically, Ogre is the most advanced This is the long position, when the material is in maximum compression.

The problem of increased compression also occurs with conventional storage containers. example For example, U.S. Pat. No. 2,711,814 describes a method for cleaning the flat bottom of a grain tank. An auger useful for is disclosed. U.S. Patent No. 2.500.043, U.S. Patent No. 3 ．． No. 755.918, No. 3, No. 155.247 and No. 3.438.517 An associated auger conveying device, such as that disclosed in It is. These patents cover a wide range of applications of auger conveying characteristics within grain bins. This is a typical example. Experience has shown that such auger devices have a high degree of compression and a rigid bottom. This has been found to be impractical in the case of scraped material forming sublayers. Auger conveyance Most of the prior art techniques that utilize equipment are for grains and grains that are less prone to compaction under pressure. It is probably for this reason that other withdrawal materials are targeted. these grains If the material is in a more flowable state, it can be unloaded using gravity flow only in a conventional storage vessel. It becomes possible to do so.

The auger conveying devices in these documents mainly direct the material to the center of the storage container. The purpose is to redistribute and maintain mutual gravitational flow throughout the unloading process. It is. These are the pressures created by a rotating auger as it advances towards the bottom of the vessel. It is not intended to respond to changes in the contraction state. In the latter case, the traditional setup Under similar conditions, output can be increased by increasing motor output and/or improving transmission equipment. Further increases in power will be necessary.

Purpose and outline of the invention One object of the present invention is to provide a looser materials such as grains, as well as cement, without increasing output demands. Auger conveying system that can process compressed materials such as The aim is to provide a

Detailed description of the invention FIG. 1 shows a dome structure 1 serving as a complete enclosure for the stored withdrawal material 11. An embodiment of the invention in combination with 0 is shown. For those skilled in the art, these materials are , a conventional loading conveyor 12 through an inlet 13 formed at the top of this dome structure. It is clear that it was loaded by This material is placed in the opening 1 4 and spread throughout the inner chamber of the dome, as shown at 15. reaches the top position. All the material 11 is placed between the central support column 16 and the attached oval. It is easily understood that the carrier substantially covers the conveyor 17, 18. these The conveying device 17.18 may optionally be a packet or paddle conveying system. However, other conveying means known to those skilled in the art may also be provided.

Because of the special advantages obtained with a hemispherical dome shape, the present invention provides a dome structure 10 , where the radial distance of the auger device 17 is Comparisons can be made throughout the volume accommodated in the facility. However, this dome-shaped The structure is suitable for more difficult storage, especially when unloading compressed materials. This is an example of a problem. This embodiment therefore provides access to the contained volume from above. Material conveyance is restricted to the opening 13 and the lower outlet 19 under more severe conditions. It will be implemented. Those skilled in the art will understand that the principle applied to this dome structure is Also applies to all types of enclosed storage areas with flat containment facilities. It is clear that

The device of the invention comprises a support column having an upper part 20, a lower end 21 and a vertical axis 22. It is equipped with 16. This support column connects the loading cone through the side opening 14 of the support column. Except for a pair of deflection plates 23 that change the direction of the material conveyed from the roller 12, It has a hollow steel column along its entire length.

This support column is located between the lower end 21 of the support column and a support bed 25 housed within the storage area. The base mount attached to is vertically oriented within fixture 24. this base The attachment orients the support post in a vertical direction within the central portion of the storage location. illustration In this embodiment, the base mount is rotatable about vertical axis 22. It is a form that can be made.

Specifically, the base mount includes an annular converging passageway or hopper 26, which The lower end 29 of the hopper of the placed on a conveyor belt or other means of transport, such as a transport truck or freight car. so that it can be carried to a pick-up position. This passage-like hopper 26 has a plurality of rows. These bearings are supported on support columns 16 and their mountings. A support ring in the form of a structure capable of supporting the load of an attached auger 17.18 Climb onto 28. This support column 16 is connected to the passage-like hopper 26 by a retaining member. are integrally connected, the bracing member being welded to the base of the support column at the negative side; On the opposite side it is welded to the lower part of the hopper structure. This means that the protection Allows the wrap 32 to slide along the top edge of the hopper and Protect from falling grains. In short, this flap 32 means that the hopper is connected to the support column. An angled sleeve that advances material from the storage location into the outlet 29 during coordinated rotation. functions as a

Similarly, the upper end 20 is rotatably supported within the top opening 33 of the dome. ing. A set of rollers or bearings 34 stabilizes the support column 16 in the vertical direction.

The drive motor 35 and chain drive device 36 are coupled at the top of the support column 16. and serves as a rotational displacement means for rotating the support column about its vertical axis 22. Ru.

Each base member 24 and upper roller system 34 cooperate to support the support column 16. It is fixed in a sturdy rotatable configuration in the central part of the storage area. Centered on vertical axis 22 The rotational speed of the dome structure should be adjusted to match the flow rate of the stored material Controlled by a chain drive 36 and an electric motor 35 housed outside the body 10. be controlled. This allows this drive system to be installed without the need to access the interior of the dome. This makes it possible to perform maintenance on the system.

At least one auger support frame 40, 41 is attached to the support column. . FIG. 4 shows two such support frames and an auger assembly 1, 7.1. 8 is attached to the support column, but only for the auger assembly 17. This will be explained in more detail. A similar description can be made regarding the second auger 18 shown in FIG. You should understand that it is possible. 2 and 3 are disclosures regarding the auger 17. The second auger is not shown because the content is similar.

The auger support frame 40 includes a proximal end 42, an intermediate portion 43, and a distal end 44. It is growing. The assembled configuration of these components extends from an upper end 44 to a lower end 42. forming an elongated truss support span at the proximal end 47 and distal end 47 of the auger 17, respectively. 48 (for combined bearing mountings, for mountings with fittings the end plate 45.4 It is equipped with 6. This auger 17 can rotate around its rotation axis 5o. The auger directs the particulate material to the hopper 26 and the distribution outlet 27. It does not function to advance along the length of. This auger support frame 4o During operation, it acts to support the auger 17, and the auger rotates around the support column 16. means for tilting the auger at different angles when doing so.

A preferred embodiment of the invention rotates the rotary drive motor 51 to the end plate 4 on the auger support frame. 6 is attached to the distal end 48. This means that the drive motor can be The prior art trend is to attach the auger to the proximal end of the auger and on the auger transport system near the This is in contrast to As a result of placing the drive motor 51 at the end of the auger, the motor It is maintained in a position above the upper surface 15 of the material. For example, the total capacity shown in Figure 1 is During storage, the drive motor 51 is oriented vertically so that the height of the material 1 It is located above 5. During unloading, the auger gradually rotates in a conical rotation pattern. Displace progressively and cut out the conical layer of sow material, respectively. At this time, the auger Since it is further tilted from the central column 16 (see imaginary line example 54.55), the rotational drive The motor 51 is always located above the material storage level. This allows the Preserves motor life and promotes continuous operation of the motor during all unloading operations do.

This is mainly due to the conventional This is in stark contrast to the technological system.

In these prior art examples, the auger conveyance system primarily Tilting of the material no longer promotes free fall of the particulate material to the outlet. It serves the function of collecting the remainder of the scrapped material left around the circumference. The present invention is based on the prior art Applications of the auger include flowable grain materials as well as cement and other materials. It is also intended to cover materials that can be compressed.

The tilting of the auger 17 connects the base of the auger support frame 42 and the lower end of the support column 16. Matching axial mounting is made possible by fittings 57. This structure When the frame is axially mounted, it rotates vertically about the tool 57, and the auger and support The frame rotates and tilts until it is (i) approximately parallel to the axis 22 of the auger support column; (ii) from the vertical direction (direction shown by the solid line with reference numeral 17) to the intermediate tilt angle (temporary (iii) the auger is adjacent to the support floor of the storage area. 2. This allows a generally horizontal position (indicated by reference numeral 55) to be reached.

This particular tilting angle selection is achieved by a variable This is done by means of suspension means 60, the axial mounting allowing rotatable tilting relative to the tool. This allows the tilting angle of the auger to be selected and adjusted.

Specifically, this suspension means has a first attachment point 62 near the top of the support column. A suspension cable 61 is provided. This cable is then connected to the auger support It is supported on a first pulley 63 mounted near the end of the frame 44.

This cable is attached to the support column between the first attachment point and the top end 20 of the support column. It is further supported on a second pulley 64, which is mounted on a second pulley 64. The second end of the suspension cable is , a winch or other drive system 65 with a fixed position relative to the support column. combined.

These winches operate in a conventional manner, winding and unwinding suspended cables. and selectively tilt the auger to the desired position. The winch has an auger With each successive 360° rotation about the vertical axis 22, the tilting movement relative to the support column The auger is incrementally advanced through a predetermined series of tilt angles of increasing angle. Figure 1 shows , only two tilting positions 1 are shown, but the perpendicular to the auger 17 is indicated by a solid line. various angles from the direction through all intermediate angles to the horizontal configuration indicated by reference numeral 55. It will be appreciated that continuous tilt angles of .

Power is supplied to each component in the form of conventional wiring. for example , rotary drive motor 35 and chain drive 65. Power to the wiring is external to the dome and has no direct access for maintenance. enable cess. For its rotatable form as part of winches and support columns The power supply is provided by a slip ring assembly 69. This conductive slip The ring provides an electrical connection, indicated by dashed line 70, which connects the length of the support column. the drive motor from the base of the support column upward from the opening in the center tube of the auger 17. The data has been extended to 51. All electrical wires should be properly secured and shielded and kept open. This prevents wear on both the trigger and the support column due to the expected movement pattern.

Next, referring to FIGS. 4 to 6, the auger 17 and the support frame 4o are a second auger attached to the end 44 of the support frame 4o against the side of the motor 51; 110. Optionally, this second auger 110 , packet or other conveyance means known to those skilled in the art, such as paddle conveyance systems. You may prepare it. The second auger 110 is rotatable. It is supported by an attached second support frame 112. the second support The support frame 112 is attached to the end of the support frame 4o by welding or other suitable means. It is attached to the side of the end. The second rotary drive motor 114 is connected to the support column 16. attached to the second support frame 112 at the proximal end or proximal end of the auger 110, The auger 110 is rotatably driven. This auger 110 is smaller than the auger 17. 2, the drive motor 114 is correspondingly smaller than the motor 51. be.

Under ideal conditions, the motor 51 is located at a position above the height 15 of the top of the material to be spread. However, in reality, the motor 51 is in contact with the material and the material in front of it is This may cause the auger 17 to access the material and There may be no opportunity to push it out of the storage dome. materials that may distort the support column drive motor 35 and cause the motor to operate inefficiently. Sometimes I do.

The second auger 110 moves material that may accumulate on the motor 51 and The material is moved downwards to the auger 17. The second motor 114 is Because it is small and allows access to the auger 17, this motor 114 is There is no significant accumulation. The motor 114 has a connection part that supplies power to the motor 51 and It has a similar auger assembly and power connection through the support column. The auger 110 is To be efficient, the material must be placed on the front side of the motor 51, i.e. while the support column is rotating. It must be installed on the side where it will be pressed. The motor 114 is connected to the second support frame. Preferably, the motor 112 is attached to the proximal end of the motor 112; 14 can be attached to the distal end of the support frame 112 if desired. Ru.

Figures 7 and 8 show that the resistance force increases as the machine gradually tilts in the horizontal direction. The present invention comprises an apparatus for providing further driving force for moving a first elongated conveying means. The fundamental characteristics of the system are disclosed. A drive motor 35 that rotates the first conveyance means It is attached to the support column 16, so that the conveyance means can be moved away from the vertical support column. Continuous adjustment of the structure causes the center of mass of the first conveying means to extend outwards, causing the structure to The force required to rotate increases. The first means of conveyance is a vertical axis! 1122-40 This increased load is due to the almost horizontal movement at a tilt angle of more than , which applies a greater traction force to the drive motor 35 and a greater drag force to the drive motor 35 . this negative The load is further compressed due to the additional drag experienced by the first conveying means as it moves against the material to be removed. , the material increases and becomes less easy to flow due to gravity.

The first conveying means can be equipped with expensive gearing to provide this large output. It is provided with a trajectory 61 of movement. This track 61 is in contact with the upper surface of the material to be removed. The drag force that propels the material across this top surface and that the withdrawn material exerts on the moving trajectory. in response to applying a tangential forward force along the rotational path of the first elongated conveying means. This is a possible form. This device is arranged at the rear of the movable track 17, The trajectory thus rides primarily on the freshly cut surface of the compressed material.

The track 61 comprises, in particular, individual track packs supported on a rotatable track carrier 64. The rotary assembly includes a rotary assembly of a board 63. At least one track element 65 (FIG. 8) is The element 65 is coupled to one of the track pads 63, and the element 65 is 2.5 mm away from the track assembly. Extend outward by 4 to 10.16 cm (1 to 4 inches) to allow the track assembly to spread. It provides a gripping edge that extends into the entire material as it moves along the plane of the material. The compression surface It is desirable that the track elements 65 be substantially separated so that they are not significantly disturbed. This way In this way, the newly cut surface remains solid and provides traction to the orbital path. and is not easily pushed back by the rotating track assembly. Orbital key The element 65 grips this surface to some extent and maintains uniform movement of the trajectory. most materials In this case, the spacing between the track elements is 30.48 to 60.96 cm (1 to 2 feet). and the preferred separation distance is 45.72 cm (1.5 feet). Almost For all materials, the spacing between track elements is 30.48 to 60.96 cm (1 to 2 The preferred separation distance is 1.5 feet (45.72 cm). ).

The track assembly includes a variable drive motor coupled to the track carrier through a drive shaft 67. 62 to rotate the track carrier and track assembly at variable speeds. Provide output. The forward shaft 68 is free to rotate and propel the advancement element of the track carrier 64. To support.

The variable speed is responsive to the speed at which the first elongate conveying means rotates about the support column. generated by a power regulating device. This output adjustment device is connected to the first elongated conveyor Provided with means for adjusting the speed of the orbital carrier to match the speed of movement of the stages. Ru. These speeds are adapted such that a torque enhancer is applied to the first conveying means. We must ensure that our strengths can complement each other. The speed of this torque enhancer is If so, the torque enhancer applies additional drag (at low speeds) and can rotate the drive motor 35 faster than its predetermined speed (at high speed) There is sex. In the latter case, the track elements can easily dig into the plow material, causing the track to have a forward force. Reduces the effectiveness of generating.

Typical speeds of the combination of the first conveying means and the attached torque enhancer is about 12 feet/minute. The actual speed is This will vary depending on the type of material involved and the degree of compaction. In all cases, the selected The speed should be adapted to the respective drives of the conveying means and the torque enhancer. Ru.

Generally, an elongated conveying means is such that the vertical height of the track that engages the surface of the sow material is approximately equal to the vertical height of the lowermost edge of the first elongated conveying means immediately preceding the moving path. is attached to the frame of the first conveying means so as to This relationship is the first elongated new exposure of the removed material due to the displacement of the surface layer of the material by means of conveyance Properly position the track to engage the surface.

To protect torque assist devices from damage caused by obstacles or to provide elongated conveying means with increased torque. A retractable suspension system 7 for protection in the event of a fall to a height below the height of the device. 0 is set. The suspension is rigidly bolted to the frame 40 of the transport means. Due to the small dimensions of the torque intensifier, its when the conveyance suddenly drops to a lower height, it can cause serious damage. Damage may occur. Also, the rotating auger of the conveying means moves the mass of material into its place. Feed through the helical blade, the fixed track pad cannot be stretched In some cases, it becomes an obstacle. Therefore, the suspension system prevents obstacles that prevent the track from moving forward. or when the first means of conveyance suddenly falls to the height below it. , comprising means for displacing the track upwardly out of the path of forward movement. illustrated In the embodiment, spring elements 71, 72 perform this necessary function.

The illustrated embodiment has additional features that allow the device to rotate out of the path of large obstacles. Equipped with safety features. This allows the device to be attached by a hinge mechanism 80. The hinge mechanism prevents the device from rotating upwardly out of the path of obstacles. and allow. Adjustment of the height angle is achieved by attaching the torque intensifier to the flange element 82. This is done by means of a threaded adjustment bolt 81 attached. Head portion 83 of the porto 81 comes into contact with a stopper plate 84 extending from the support frame 40 . selectively with this , the vertical displacement slidably supports the torque intensifier on a vertical rod. This can be achieved by

Numerous changes may be made to the structure to apply the inventive features of this specification. It is clear that this is possible. For example, in FIG. A track assembly is shown having a track portion that is generally flat. This form is generally Although preferred, there are also types of withdrawal materials for which circular tracks or drums are suitable. Ru. As another example, the illustrated track elements include a mountain that is coupled to the track assembly at the side. a profile, the other side projecting outwardly from the track assembly to engage the plow material; Provides a gripping edge. Other forms of gripping elements can also be readily adopted.

As shown in FIG. 1, the second elongated conveying means 18 is opposite the first conveying means 17 They can be placed in the following relationship. Its structure is similar to the first structure, and the torque The augmentation device is arranged rearward with respect to the second conveyance means.

In general, these variants all embody a common method consisting of the following steps.

That is, a support column having an upper end, a lower end, and a vertical axis is placed at a central location in the storage area. The stage of doing; The base mounting provides a constant vertical orientation to the support column within the central portion of the storage area. between the lower end of the support column and the support bed housed within the storage area: first Directing the particulate material along the length of the conveying means to a dispensing outlet near the base of the support column. a first elongate delivery means for advancing the first elongate, the first elongate having a proximal end and a distal end; attaching the delivery means to the first support frame; attaching the proximal end of the first support frame to the first support frame; Axial installation is done by attaching to the support column with a tool, and attaching the first conveying means and the first support frame. (i) in a vertical direction such that the first conveying means is substantially parallel to the vertical axis of the support column; (ii) through an intermediate tilting angle; and (iii) the first conveying means reaches the storage area. enabling rotatable tilting to a substantially horizontal direction adjacent to the support floor; A first drive motor further comprising means for applying a driving force to the first conveyance means. coupling the first conveying means to the first support frame; the first conveying means; is at least partially buried in the entire material, and the tilting angle of the first conveying means with respect to the support bed is Storing the scrap material in a horizontal storage area where the angle is 50° or more: activating the first drive motor on the first conveying means to tilt the stored material; to support the free fall along the flow path to the outlet port of the support floor of the storage area. and start discharging the material; at the same time as the actuated drive motor The conveying means is rotated about the vertical axis of the support column, and the torque intensifier is applied to the material being spread.
