[0004] The technical solution has the following problems in practice: it requires the installation of a gantry beam and its drive mechanism for the suspension arch-breaking and scraping device in the warehouse. For the renovation of old warehouses, most do not have the conditions to add a gantry beam. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the problems existing in the above and / or prior art, this utility model is proposed.

[0007] The purpose of this utility model is to overcome the problems existing in the prior art and provide a warehouse scraper and discharge machine. The arch-breaking device is directly set on the front side of the discharge machine, which can break the high material layer in front of the discharge machine in advance. There is no need to build a gantry beam or modify the warehouse, which greatly reduces the construction cost.

[0008] To solve the above technical problems, this utility model provides a warehouse scraping and discharging machine, which includes a discharging frame extending along the full width of the warehouse. A traveling mechanism is provided in the middle of the discharging frame in the front-to-back direction. Discharging augers that convey material to the central pit are respectively provided on the front and rear sides of the discharging frame. A scraping fixing frame is fixed on the top of the discharging frame. A scraping floating frame that can be moved horizontally along the length of the scraping fixing frame is provided on the front and rear sides of the scraping fixing frame. Multiple scraping augers that are evenly spaced and extend vertically are provided on the outer sides of the two scraping floating frames.

[0009] Furthermore, the scraper fixing frame is an inverted trapezoidal shape that is wider at the top and narrower at the bottom, and the upper ends of the scraper floating frame and each scraper auger are inclined outward.

[0010] Furthermore, the front and rear sides of the upper end of the scraper fixing frame are respectively provided with I-beams extending along the width direction of the storage room; multiple floating frame upper supports are welded to the back of the upper end of the scraper floating frame, and upper support rollers are installed in pairs on each floating frame upper support, with each pair of upper support rollers supporting the upper and lower end faces of the I-beam respectively.

[0011] Furthermore, a scraper guide rail is welded to the top of the I-beam, and the upper support lug roller is a grooved wheel supported on the scraper guide rail.

[0012] Furthermore, T-shaped steel extending along the width of the storage compartment is provided on the front and rear sides of the lower end of the scraper fixing frame; multiple floating frame lower supports are welded to the back of the lower end of the scraper floating frame, and lower support rollers are installed in pairs on each floating frame lower support, with each pair of lower support rollers clamping on both sides of the T-shaped steel.

[0013] Furthermore, the upper front and rear sides of the scraper fixing frame are respectively provided with translation scraping drive mechanisms. The translation scraping drive mechanism includes a translation drive motor reducer, a translation scraping chain and a translation scraping driven wheel. The output end of the translation drive motor reducer is equipped with a translation scraping drive wheel. The translation scraping chain passes around the translation scraping drive wheel and the translation scraping driven wheel and its two ends are respectively fixed on the corresponding scraping floating frame.

[0014] Furthermore, the traveling mechanism includes a traveling drive shaft located in the upper middle part of the outbound frame. A traveling drive sprocket is mounted on the traveling drive shaft. Travel redirection sprockets are respectively provided on the lower front and rear sides of the traveling drive sprocket. The traveling traction chain is Ω-shaped and passes around the traveling drive sprocket and the traveling redirection sprocket. The two ends of the traveling traction chain are respectively fixed on the traveling chain tensioning device.

[0015] Furthermore, the walking chain tensioning device includes a bracket welded part with its bottom fixed to the ground. A redirecting light wheel is installed at the lower part of the bracket welded part. The end of the walking traction chain extends upward around the redirecting light wheel. The inner and outer sides of the walking traction chain are clamped by an inner clamping plate and an outer clamping plate. An inner clamping plate sliding shaft is fixed at the upper and lower ends of the inner clamping plate, and the two ends of the inner clamping plate sliding shaft are respectively embedded in the opposing slots of two track grooves. The inner sidewalls of the two track grooves are respectively fixedly connected to the upper two sides of the bracket welded part. The outer clamping plate is provided with clamping plate claws that are embedded between the links of the walking traction chain. The left and right sides of the outer clamping plate are fixedly connected to the inner clamping plate by clamping plate screws. An outwardly bent outer clamping plate base is welded to the bottom of the outer clamping plate. A tensioning cylinder is connected below the outer clamping plate base, and the bottom of the tensioning cylinder is supported on the ground.

[0016] Compared with the prior art, the present invention has achieved the following beneficial effects: 1. The arch-breaking mechanism and the discharge mechanism move forward together, which can break up the slab material layer about 10 meters in front of the discharge machine from top to bottom in advance, and avoid the formation of dangerous cliffs by hollowing out the lower part of the material pile during the arch-breaking process. The slab material at the top is gradually broken up and collapses downward in advance, forming a safe slope, which prevents the material pile at the top from breaking off in large pieces and causing overturning, damaging the discharge equipment.

[0017] 2. Pre-breaking the collapsing material will form a relatively low and continuous pile of loose material in front of the discharge machine. The discharge machine can easily discharge these low and continuous piles of material at a uniform speed, which can more continuously and stably transport the material to the next production line and ensure the stable supply of material to the production line.

[0018] 3. Divide the entire width of the warehouse into several units and scrape and break up the arches in different areas simultaneously, increasing the speed of arch breaking and scraping by several times, thereby improving the speed and efficiency of warehouse exit.

[0019] 4. Several discharge walking chains are buried along the depth direction on the floor of the storage room. The discharge machine moves forward along the discharge walking chains, driving the transverse discharge mechanism forward. Two material blocking belts are covered above the pit. The bottom of the material blocking belts is reliably supported by the grid, which can support the material above and prevent the material from leaking in. When discharging, as the discharge machine moves forward, the belt at the location of the discharge machine is pulled away from the grid, so that the material can directly pass through the grid and fall into the pit, where it is sent out by the buried scraper conveyor.

[0031] In the following description of this utility model, the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not mean that the device must have a specific orientation.

[0032] To make the technical means, creative features, achieved objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0034] like Figures 1 to 3 As shown, the material discharge machine for a storage silo of this utility model includes a discharge frame 1 extending along the full width of the storage silo. A traveling mechanism is located in the middle of the discharge frame 1 in the front-to-back direction. Discharge augers 2 for conveying material to the central pit are located on the front and rear sides of the discharge frame 1, respectively. The traveling mechanism includes a traveling drive shaft located in the upper middle part of the discharge frame 1. A traveling drive sprocket 9 is mounted on the traveling drive shaft. Travel redirecting sprockets 10 are located on the lower front and rear sides of the traveling drive sprocket 9, respectively. A traveling traction chain, in an Ω shape, passes around the traveling drive sprocket 9 and the traveling redirecting sprockets 10. The two ends of the traveling traction chain are fixed to a traveling chain tensioning device. Multiple traveling traction chains are provided in the width direction of the discharge frame 1.

[0035] The walking motor reducer drives the walking drive shaft to rotate, and the walking drive sprocket 9 moves forward along the walking traction chain, driving the discharge frame 1 forward. At the same time, the discharge augers 2 on both sides output the material in the width direction of the warehouse to the central pit, realizing the discharge.

[0036] To prevent the material discharge machine from forming a chasm below the material pile as it moves forward, the material pile at a higher elevation must be scraped and the arch broken during discharge, causing the pile to collapse to the ground in advance.

[0037] The specific design is as follows: A scraping fixing frame 3 is fixed on the top of the discharge frame 1. Scraping floating frames 4, which can be moved horizontally along the length of the scraping fixing frame 3, are respectively provided on the front and rear sides of the scraping fixing frame 3. Multiple evenly spaced scraping augers 5 extending vertically are provided on the outer sides of the two scraping floating frames 4. The scraping fixing frame 3 is an inverted trapezoid with a wider top and a narrower bottom. The upper ends of the scraping floating frames 4 and each scraping auger 5 are inclined outward.

[0038] Each scraper auger 5 rotates under the drive of the scraper auger motor reducer, conveying the material pile downwards. At the same time, the scraper floating frame 4 carries each scraper auger 5 to move horizontally along the width of the silo for a certain distance, and moves horizontally back and forth in a cycle. In this way, the arch-breaking scraping of material can be achieved in the entire width of the silo. This can form a slope that narrows at the top on the material layer in front, preventing the material pile from collapsing and damaging the discharge machine.

[0039] The upper end of the scraper fixing frame 3 has I-beams 3a extending along the width of the storage compartment on both the front and rear sides. Multiple upper support ears 4a are welded to the back of the upper end of the scraper floating frame 4. Each upper support ear 4a has a pair of upper support ear rollers 4c installed on it. The axis of each pair of upper support ear rollers 4c is horizontal and they are supported on the upper and lower end faces of the I-beams 3a respectively. A scraper guide rail 3b is welded to the top of the I-beam 3a. The upper support ear rollers above it are grooved wheels 4b, which are supported on the scraper guide rail 3b to achieve front-to-back direction limiting and suspend the scraper floating frame 4, bearing its weight. The upper support ear rollers 4c below the I-beam 3a serve as height-directing limiting, ensuring reliable contact between the grooved wheels 4b and the scraper guide rail 3b.

[0040] T-shaped steel 3c extending along the width of the storage compartment is provided on the front and rear sides of the lower end of the scraper fixing frame 3. The width of the storage compartment is the length direction of the scraper fixing frame 3 and the scraper floating frame 4. Multiple floating frame lower support ears 4d are welded to the back of the lower end of the scraper floating frame 4. Lower support ear rollers 4e are installed in pairs on each floating frame lower support ear 4d. The axis of each pair of lower support ear rollers 4e is vertical and they are clamped on both sides of the T-shaped steel 3c to play a role in straightening and ensuring the tilt angle of the scraper floating frame 4.

[0041] The upper front and rear sides of the scraper fixing frame 3 are respectively equipped with translation scraping drive mechanisms. The translation scraping drive mechanism includes a translation drive motor reducer 6, a translation scraping chain 7, and a translation scraping driven wheel 8. The output end of the translation drive motor reducer 6 is equipped with a translation scraping drive wheel. The translation scraping chain 7 passes around the translation scraping drive wheel and the translation scraping driven wheel 8, and both ends are fixed to the corresponding scraping floating frame 4 by tensioning mechanisms. After the translation drive motor reducer 6 is started, the translation scraping drive wheel drives the translation scraping chain 7 to move, thereby pulling the scraping floating frame 4 to move laterally along the scraping guide rail 3b.

[0042] like Figure 4 , Figure 5As shown, the walking chain tensioning device includes a bracket welded part 11, a redirecting light wheel 12, an inner clamping plate 13, an outer clamping plate 14, a track groove 15, a tensioning cylinder 16, and a limiting plate 17. The bottom of the bracket welded part 11 is fixed to the ground. A pair of redirecting light wheels 12 are installed on the lower part of the bracket welded part 11. The lower redirecting light wheel 12 is located in the bottom inner cavity of the bracket welded part 11, and the upper redirecting light wheel 12 is close to the outer side. The end of the walking traction chain 18 extends upward around the redirecting light wheel 12 in an S-shape.

[0043] A bracket fixing plate is welded to the upper part of the bracket weld 11 on the side facing the walking traction chain 18. The two sides of the bracket fixing plate extend beyond the side wall of the bracket weld 11 to form bracket weld flanges 11a. The bracket weld flanges 11a are provided with multiple screw holes and are fixed with track grooves 15. The openings of the track grooves 15 on both sides face each other.

[0044] The inner clamping plate 13 is placed inside the walking traction chain 18, that is, between the walking traction chain 18 and the bracket fixing plate. The upper and lower ends of the inner clamping plate 13 are respectively fixed with inner clamping plate sliding shafts 13a. The two ends of the inner clamping plate sliding shafts 13a are respectively embedded in the opposing slots of the two track grooves 15, ensuring that the inner clamping plate sliding shafts 13a and the inner clamping plate 13 move up and down along the track grooves 15.

[0045] The outer clamping plate 14 is located on the outside of the traveling traction chain 18. The end face of the outer clamping plate 14 facing the traveling traction chain 18 is provided with clamping claws 14a, which are inserted between the links of the traveling traction chain 18, securing two links vertically. The left and right sides of the outer clamping plate 14 are provided with outer clamping plate bosses 14b, which abut against the inner clamping plate 13. Clamping plate screws 14d pass through the through holes of the outer clamping plate bosses 14b and are screwed into the screw holes of the inner clamping plate 13, thus fixing the outer clamping plate 14 to the inner clamping plate 13.

[0046] The bottom of the outer clamping plate 14 is welded with an outwardly bent outer clamping plate base 14c, and the top of the outer clamping plate base 14c is connected to the outer wall of the outer clamping plate 14 by a triangular rib plate. The bottom of the tensioning cylinder 16 is supported on the ground, and the top of the piston rod of the tensioning cylinder 16 is hinged to the bottom of the outer clamping plate base 14c.

[0047] The top of the bracket weld 11 is provided with a bracket claw 11b extending toward the walking traction chain 18. The bracket claw 11b can be inserted between the links of the walking traction chain 18 to lock the walking traction chain 18.

[0048] The outer walls of the two track grooves 15 are provided with a row of track groove adjusting screw holes 15a along the height direction. The upper or lower side of the outer clamping plate 14 is provided with a limiting plate, or both the upper and lower sides are provided with limiting plates. The two ends of the limiting plate are respectively screwed into the corresponding track groove adjusting screw holes 15a. The middle part of the limiting plate 17 is provided with a limiting plate claw 17a, which is embedded between the chain links to lock the walking traction chain 18.

[0049] During tensioning, the tensioning cylinder 16 pushes upward, driving the outer clamping plate 14 and clamping plate claws 14a upward through the outer clamping plate base 14c. The clamping plate claws 14a are engaged in the chain links, driving the end of the travel traction chain 18 upward. During this process, the inner clamping plate sliding shaft 13a slides upward along the groove of the track groove 15 to avoid skewing. Then, the travel traction chain 18 is bent towards the top of the bracket weldment 11, so that the bracket claws 11b are engaged between the chain links of the travel traction chain 18 to lock the travel traction chain 18. Then, the clamping plate screws 14d are loosened, the piston rod of the tensioning cylinder 16 retracts, the outer clamping plate 14 and outer clamping plate base 14c descend to the low position, and the inner clamping plate 13 also slides down to the low position. After confirming that the clamping plate claws 14a are engaged in the lower chain links, the clamping plate screws 14d are reinstalled to lock the inner clamping plate 13 and the outer clamping plate 14, and the tensioning cylinder 16 can then proceed to the next round of lifting and tensioning.

[0050] After the walking traction chain 18 is tensioned in place, the free end of the walking traction chain 18 can be locked by inserting it into the bracket claw 11b, or a limit plate 17 can be installed and further locked by the limit plate claw 17a.
