Background Art

[0002] The yard of a bungalow warehouse is rectangular, and the width of the yard is relatively wide, often reaching 30 to 40 meters. There is a trend of getting wider and wider, and the depth sometimes reaches more than 200 meters. Materials need to be discharged through a special warehouse discharge machine. The Chinese utility model patent with publication number CN 205346364U discloses a track-type warehouse discharge machine applied to the bottom of a bungalow, including a travel drive motor, an auger guard support sleeve, an auger guard baffle assembly, an auger spiral drive, an intermediate support wheel, an auger spiral drive guard bracket, an auger assembly, a tail bearing seat, a travel track, a track cleaning shoe, a travel sprocket, and a cleaning plate.

The auger spiral drive is connected to the auger assembly through a shaft, and the blades on the auger assemblies on both sides of the auger spiral drive rotate in opposite directions. The auger blades are serrated, and the auger spiral drive is fixedly installed on the auger spiral drive guard bracket. An intermediate walking support wheel is installed under the auger spiral drive guard bracket, and the intermediate walking support wheel is supported on the steel rail above the ground.

[0003] The warehouse unloading machine can unload materials with good fluidity such as soybeans. When the flat warehouse stores highly compacted materials such as soybean meal, the materials will become severely compacted after being piled up in the warehouse, losing fluidity and becoming a whole similar to concrete. It is difficult for the above-mentioned warehouse unloading machine to complete the unloading task.

[0004] The Chinese utility model patent application with publication number CN116002405A discloses a high-layer compacted material discharging machine, a flat warehouse discharging system and a discharging method, including a main frame extending in the horizontal direction and capable of moving in the vertical direction, with discharging active and driven sprockets provided at both ends of the main frame, a discharging chain wrapped between the two discharging sprockets, and multiple scraper assemblies evenly fixed along the circumference of the discharging chain, and an arch-breaking device installed on the top of the main frame, which can cause the high-layer compacted material in front of the discharging machine to collapse in advance. The arch-breaking auger is inserted into the compacted material at the front height in advance, rotating while reciprocating horizontally, and cutting a horizontal continuous fracture on the cliff face of the upper material layer in front to cause it to collapse downward in advance, so that the discharging machine can transport the material to the pit.

[0006] In order to increase the storage capacity per unit area, storage units have piled materials higher and higher, and it is increasingly common to reach a height of more than 10 meters. After long-term stacking and adhesion, soybean meal becomes a compacted whole similar to concrete. Although the arch-breaking auger is inserted into the compacted material at the front in advance, the horizontal incision is about 2 meters from the ground. The compacted material pile above is very high and heavy, and difficult to break. As the bottom is hollowed out, the material pile above will still collapse in a concentrated manner, smashing the warehouse discharge machine equipment. As the use of soybean meal in my country increases, it is urgent to solve the problem of arch-breaking and warehouse discharge of high-layer compacted materials such as soybean meal.

[0041] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0043] like Figures 1 to 8 As shown, the suspended scraper device for compacted materials of the utility model includes an arch-breaking swing frame 1 suspended under a crane 10, translation brackets 2 located on both sides of the arch-breaking swing frame 1 and an arch-breaking mechanism located on the translation bracket 2. The crane 10, the arch-breaking swing frame 1 and the translation bracket 2 all extend along the width direction of the flat warehouse.

[0044] The arch-breaking swing frame 1 includes a plurality of mutually parallel and inverted tripods 1a, each tripod 1a is provided with a central vertical rod along the height line of the bottom edge, and the middle of the two oblique sides of each tripod 1a is connected to each other through a central beam, thereby improving the strength and rigidity of the tripod 1a. The central vertical rods of adjacent tripods 1a are connected to each other through a connecting rod steel frame 1d, so that the arch-breaking swing frame 1 becomes a rigid whole, and the connecting rod steel frame 1d includes a rectangular frame, and the diagonal lines and the midpoints of the long sides of the rectangular frame are connected to the central connecting block.

[0045] The upper and lower ends of the front and rear sides of the arch-breaking swing frame 1 are respectively provided with swing frame rails, and the swing frame rails include a swing frame upper rail 1f and a swing frame lower rail 1g, and each swing frame upper rail 1f and swing frame lower rail 1g are parallel to each other and extend along the length direction of the arch-breaking swing frame 1. The specific method can be as follows: the upper bottom edge of each tripod 1a extends outward to form a tripod upper beam 1b, and the two swing frame upper rails 1f are symmetrically fixed above the two ends of the tripod upper beam 1b; the lower vertex of each tripod 1a is welded with a tripod lower beam 1c parallel to the tripod upper beam 1b, and the two swing frame lower rails 1g are symmetrically fixed above the two ends of the tripod lower beam 1c, so that the cross-sectional shape of the arch-breaking swing frame 1 is an inverted trapezoidal shape with a wide top and a narrow bottom.

[0046] Translation brackets 2 are symmetrically arranged on the front and rear oblique sides of the arch-breaking swing frame 1. The backs of the two translation brackets 2 are supported on the swing frame track through rollers respectively and can translate along the swing frame track.

[0047] The translation support 2 includes a broken arch beam 2a and a rigid truss 2d. Each broken arch beam 2a extends vertically and is parallel to each other and arranged at equal intervals. Adjacent broken arch beams 2a are connected to each other as a whole through the rigid truss 2d. The outer frame of each rigid truss 2d is rectangular and a translation drive seat 2e is provided in the center. The diagonal line and the midpoint of the long side of the rectangular frame are respectively welded to the translation drive seat 2e through a connecting rod.

[0048] The upper and lower parts of the back sides of the two broken arch beams 2a are respectively fixed with translation bracket ear seats 2b, and the lower parts of the translation bracket ear seats 2b are respectively installed with translation bracket rollers 2c, and each translation bracket roller 2c is respectively supported in the swing frame upper rail 1f or the swing frame lower rail 1g.

[0049] The upper rail 1f of the swing frame and the lower rail 1g of the swing frame are both track I-beams, and the translation bracket rollers 2c are arranged in pairs and symmetrically embedded on both sides of the corresponding track I-beams; they can not only roll along the I-beams, but also enable the arch-breaking swing frame 1 to obtain precise positioning in its own width direction.

[0050] Two translation drive reducers 4 are installed in the middle of the arch-breaking swing frame 1, and the translation bracket 2 is driven by the translation drive reducer 4 through the translation drive chain 5. The translation drive reducer 4 can be installed in a mirror-symmetrical manner in the front and rear directions. The input end of the translation drive reducer 4 is driven by the translation drive motor 3. A translation drive sprocket 4a is installed on the output shaft of the translation drive reducer 4. The translation drive sprocket 4a is connected to the translation driven sprocket 6a through the translation drive chain 5. The translation drive chain 5 is parallel to the swing frame track. The translation driven sprocket 6a is installed on the translation driven shaft 6. The translation driven shaft 6 is supported on the arch-breaking swing frame 1 through a bearing seat.

[0051] A vertical waist-shaped groove 2f is provided at the center of each translation drive seat 2e, in which a translation drive block 5a is embedded in the vertical waist-shaped groove 2f of one of the translation drive seats 2e. The root of the translation drive block 5a is cantilevered and fixed on a link of the translation drive chain 5, so that the translation drive chain 5 can rotate continuously to avoid impact caused by frequent braking and turning.

[0052] Each arch-breaking vertical beam 2a is respectively installed with an arch-breaking auger 8 parallel thereto, and the arch-breaking auger 8 on the front and rear sides is arranged in an inverted eight-shape, and the parts of each arch-breaking auger 8 close to the upper and lower ends are respectively supported on their own arch-breaking vertical beams 2a through bearing seats.

[0053] The middle section of each arch-breaking auger 8 is driven by the output end of the arch-breaking auger reducer 7a through a chain, and the input end of each arch-breaking auger reducer 7a is driven by the arch-breaking auger motor 7, and the arch-breaking auger reducer 7a is fixed on the back of the arch-breaking vertical beam 2a.

[0054] The centers of the upper beams 1b of each tripod in the arch-breaking swing frame 1 are respectively hinged to the bottom of the traveling crane 10 through the swing frame pin 1e. The arch-breaking swing frame 1 matches the width direction of the bungalow warehouse and is suspended by the traveling crane 10 to move forward along the depth direction of the bungalow warehouse, i.e., facing the material pile. When the device is pressed on the material pile, the arch-breaking swing frame 1 can swing outward at a certain angle. On the one hand, it has adaptive ability, allowing a certain range of error between the forward speed of the scraping device and the warehouse discharge machine on the ground; on the other hand, the tilted arch-breaking swing frame 1 automatically has a counterweight function, so that the arch-breaking auger 8 is pressed on the slope of the material pile to facilitate scraping. In addition, due to the tilt of the arch-breaking swing frame 1, the arch-breaking auger 8 is pressed obliquely on the material pile, and a stable slope with a narrow top and a wide bottom is formed after scraping the material, avoiding the risk of concentrated collapse and damaging the warehouse discharge machine.

[0055] Each arch-breaking auger motor 7 drives the arch-breaking auger reducer 7a to operate, and each arch-breaking auger reducer 7a drives the arch-breaking auger 8 to rotate. Taking the arrangement of six arch-breaking auger 8 in the width direction as an example, the width direction of the bungalow warehouse is divided into six areas, and each arch-breaking auger 8 is only responsible for arch-breaking and scraping materials in one-sixth of the area, which greatly improves the scraping speed. The six arch-breaking auger 8 rotates at the same time, and scrapes the compacted materials such as soybean meal on the front slope vertically. The compacted materials fall on the ground after being scraped off. The lower pitch of each arch-breaking auger 8 is greater than the middle and upper pitch, which is convenient for conveying or loosening the materials on the ground upward, and convenient for the warehouse discharge machine to discharge materials synchronously.

[0056] While each arch-breaking auger 8 is rotating, the translation drive motor 3 drives the translation drive reducer 4 to operate, and the translation drive reducer 4 drives the translation driven sprocket 6a to rotate through the translation drive sprocket 4a and the translation drive chain 5, and the translation drive chain 5 drives the translation drive block 5a to rotate continuously. The translation drive block 5a is embedded in the vertical waist groove 2f of the translation drive seat 2e to drive the translation drive seat 2e and then drive the entire translation bracket 2 to move horizontally along the swing frame upper rail 1f and the swing frame lower rail 1g.

[0057] When the translation drive block 5a follows the translation drive chain 5 to the lower layer, the translation drive block 5a is located in the lower part of the vertical waist-shaped groove 2f, driving the translation bracket 2 to translate forward, and each arch-breaking auger 8 rotates while following the translation bracket 2 to translate forward, realizing forward scraping.

[0058] When the translation drive block 5a follows the translation drive chain 5 to the upper layer, the translation drive block 5a is located in the upper part of the vertical waist-shaped groove 2f, driving the translation bracket 2 to translate in the opposite direction. While each arch-breaking auger 8 rotates, it follows the translation bracket 2 to translate in the opposite direction to realize reverse scraping, and this cycle is repeated.

[0059] In addition, arch-breaking auger 8 is provided on the front and rear sides of the arch-breaking swing frame 1 to facilitate bidirectional discharging. A sliding power supply device 9 is hinged at the bottom of the arch-breaking swing frame 1, and the lower end of the sliding power supply device 9 is plugged into the top of the warehouse discharge machine at the lower rear side, and draws power from the warehouse discharge machine below, and swings with the warehouse discharge machine, allowing a certain speed difference between the arch-breaking swing frame 1 and the warehouse discharge machine at the lower rear side.
