Description

Technical Field

[0001] The invention relates to a discharging device, in particular to a silo integral scraping and arch breaking discharging device, which can be used for discharging materials from a flat silo storing soybean meal, and belongs to the technical field of silo discharging equipment. Background Art

[0002] The storage yard of a flat 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. Special warehouse unloading machines are required for unloading.

[0003] The Chinese invention patent with publication number CN 205346364U discloses a rail-type warehouse unloading machine applied to the bottom of a flat warehouse, including a travel drive motor, an auger shield support sleeve, an auger shield baffle assembly, an auger spiral drive, an intermediate support wheel, an auger spiral drive shield bracket, an auger assembly, a tail bearing seat, a travel track, a track cleaning slide, a travel sprocket, and a cleaning plate. The travel track is fixed on the track ring beams on both sides of the flat warehouse, the travel sprocket is meshed with the travel track, the two sides of the auger assembly are respectively installed on the tail bearing seat, the tail bearing seat is assembled and fixed on the fixed bracket of the track cleaning slide, and the travel drive motor is located at the bottom of the flat warehouse. On both sides of the warehouse discharge machine, it is fixed on the track cleaning slide through a connecting bracket, the auger guard support sleeve is fixedly installed on the auger guard baffle assembly by bolts, the auger guard baffle assembly is sleeved on the auger assembly, and cleaning plates are installed on the upper and lower sides of the auger guard baffle assembly. The auger spiral drive is connected to the auger assembly through a shaft, the blades on the auger assemblies on both sides of the auger spiral drive rotate in opposite directions, and the auger blades are serrated. The auger spiral drive is fixedly installed on the auger spiral drive guard bracket, and 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.

[0004] 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.

[0005] The Chinese invention 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 horizontally continuous fracture on the cliff face of the upper material layer in front to cause it to collapse downward in advance, so as to facilitate the discharging machine to transport the material to the pit.

[0006] This technical solution still has the following problems in practice: In order to increase the storage capacity per unit area, the storage units have piled higher and higher materials, and it is more and more common to reach a height of more than 12 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 and damage 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.

When the warehouse discharge machine changes its traveling direction, the overall scraping and arch-breaking discharge device of the warehouse can change its tilting direction and still complete the arch-breaking of the material layer in front, thus realizing dual-purpose of one machine; 5. When using a single-cylinder unloader to discharge materials, the door frame of the unloading door is supported on the stop of the pit, and the top is flush with the floor of the warehouse, so that there are no obstacles above the floor of the warehouse and the storage space of the warehouse is increased; the flap door is opened and closed by the unloading cylinder.

When the unloading cylinder opens the flap door, the angle between the flap door and the horizontal plane can reach nearly 60°, and the unloading is faster and smoother; the flap door can achieve natural sealing to avoid leakage; only one unloading cylinder is used to complete the opening and closing action. After the flap door is closed, it automatically realizes self-locking. When the unloading cylinder is not working, the flap door is still in a reliably closed state. While ensuring reliability, the structure is greatly simplified and the failure points are also reduced; 6. When using a two-cylinder unloader to discharge materials, the unloading door is opened and closed by the unloading cylinder. When the unloading door is opened downward, the material above naturally flows into the pit and is sent out through the buried scraper conveyor. After the unloading door is closed, the lock pin driving cylinder drives each lock pin to extend and support under the unloading door support rod. When the unloading cylinder is not working, the unloading door is in a reliably closed state. After removing the inspection panel, the door shaft and lock pin driving mechanism can be repaired or replaced from the top, which makes maintenance more convenient.

The scraper tooth plates 15 are made of angle steel and have tooth surfaces facing outward, and the back of each scraper tooth plate 15 is fixed to the corresponding chain link of each scraper chain 10, and a wear-resistant guide plate 16 is respectively fixed to the middle part of the back of each scraper tooth plate, and the grooves of each wear-resistant guide plate 16 are respectively supported on the corresponding vertical rails 3 and match each other, and each vertical rail 3 is fixed in the rectangular frame 2 and is parallel to the left and right frame 2c.

[0032] A scraper reducer 5 is fixed below the middle section of the upper crossbeam 2a, the input end of the scraper reducer 5 is driven by the scraper motor 4, and a driving sprocket 5a is installed on the output shaft of the scraper reducer 5; the driving sprocket 5a is connected to the driving shaft sprocket 7a through a short chain 6, the driving shaft sprocket 7a is installed in the middle of the driving shaft 7, and the two ends of the driving shaft 7 are respectively connected to the upper transmission shaft 9 through a coupling. A counterweight 18 is fixed below the lower crossbeam 2b of the rectangular frame 2, and the counterweight 18 is provided in multiple groups and is easy to disassemble and assemble, so that the entire center of gravity on the rectangular frame 2 falls on the hinge shaft at the lower end of the hanging assembly 1.

The reversing winch located in the front side of the forward direction of the warehouse discharge machine 29 retracts the wire rope, and the reversing winch at the rear releases the wire rope, and the middle part of the rectangular frame 2 rotates around the hinge shaft at the lower end of the hanging component 1, so that the upper end of the overall scraping and arch breaking discharge device of the warehouse is tilted forward, and after contacting the material pile, a slope is formed on the material pile by scraping the material.

[0034] At this time, the upper end of the rectangular frame 2 is higher than the top of the traveling beam 17, ensuring that a slope is scraped out on the front side of the traveling beam 17, ensuring that the traveling beam 17 moves forward smoothly following the warehouse discharge machine.

[0035] After the scraper motor 4 is started, the drive sprocket 5a is rotated after being decelerated by the scraper reducer 5, and the drive sprocket drives the driving shaft sprocket 7a to rotate through the short chain 6, and the driving shaft sprocket 7a drives the upper transmission shaft 9 to rotate through the driving shaft 7, and the upper transmission shaft 9 drives each traction sprocket 9a to rotate synchronously, and each traction sprocket 9a drives the lower redirecting sprocket 13a to rotate through the scraper chain 10, and each scraper chain 10 drives each scraper tooth plate 15 on it to scrape upward while running.

The upper end of the pit is covered with multiple unloaders, which can be single-cylinder unloaders or double-cylinder unloaders B. Before loading, each unloader is closed, and the floor of the warehouse is in a flat state. When discharging, the unloaders are opened in turn, and the materials above the pit first flow into the pit by gravity, and are sent out by the buried scraper conveyor 30. As the warehouse discharge machine 29 moves forward, the materials in the width direction of the warehouse are transported toward the pit.

[0044] The outer clamping plate 24 is located outside the traction chain 28. The end surface of the outer clamping plate 24 facing the traction chain 28 is provided with a clamping plate claw 24a, which is embedded between the links of the traction chain 28 to clamp two links up and down. The left and right sides of the outer clamping plate 24 are provided with outer clamping plate bosses 24b, which abut against the inner clamping plate 23. The clamping plate screw 24d passes through the through hole of the outer clamping plate boss 24b and is screwed into the screw hole of the inner clamping plate 23, so that the outer clamping plate 24 is fixedly connected to the inner clamping plate 23.

[0045] The bottom of the outer splint 24 is welded with an outer splint base 24c bent outward, and the top of the outer splint base 24c is connected to the outer wall of the outer splint 24 through a triangular rib plate. The bottom of the tensioning cylinder 26 is supported on the ground, and the top of the piston rod of the tensioning cylinder 26 is hinged below the outer splint base 24c.

During this process, the inner clamping plate sliding shaft 23a slides upward along the notch of the track groove 25 to avoid skewing. Then, after the traction chain 28 is bent toward the top of the bracket weldment 21, the bracket claw 21b is embedded between the chain links of the traction chain 28 to lock the traction chain 28, and then the clamping plate screw 24d is loosened, the piston rod of the tensioning oil cylinder 26 is retracted, the outer clamping plate 24 and the outer clamping plate base 24c are lowered to the low position, and the inner clamping plate 23 also slides down to the low position. After confirming that the clamping plate claw 24a is stuck in the lower chain link, the clamping plate screw 24d is reinstalled to lock the inner clamping plate 23 and the outer clamping plate 24, and the tensioning oil cylinder 26 can enter the next round of lifting and tensioning.

[0049] After the traction chain 28 is tensioned in place, the free end of the traction chain 28 can be clamped into the bracket claw 21b to achieve locking, and the limit plate 27 can also be installed to further lock it through the limit plate claw 27a.

[0050] like Figures 12 to 16 As shown, the double cylinder unloading machine B includes a door frame 31, a unloading door 33, a unloading cylinder 34, a lock pin 37 and a lock pin driving cylinder 35. The door frame 31 covers the upper port of the pit, the short side of the door frame is supported on the stoppers on both sides of the pit, and the long side spans between the stoppers on both sides of the pit. The middle of the two long sides of the door frame 31 is connected through the middle frame 32, and the two short sides of the door frame 31 are respectively hinged with the unloading door 33 through the door shaft 33a. The door shaft 33a is provided with two coaxial lines and is respectively hinged on both sides of the width direction of the unloading door 33. The top of the short side of the door frame 31 corresponding to the door shaft 33a is respectively provided with an inspection window and covered with a door frame inspection panel 31b. Opening the door frame inspection panel 31b makes it easy to pull out the door shaft 33a from the top and replace it.

[0051] The free ends of the two discharge doors 33 extend obliquely downward from the middle frame 32, and the angle between the top surface of the discharge door 33 and the horizontal plane is 14° to 18°; thus, the discharge door 33 can be opened to obtain a larger opening angle, usually up to 58° to 60°, so that the discharge is smoother and faster. The discharge door 33 is provided with door side baffles 31c on both sides, and the door side baffles 31c cover the gaps on both sides of the discharge door to prevent leakage.

[0052] Vertical brackets 31a extending downward are fixed to the middle of the two short sides of the door frame 31, the lower ends of the cylinder bodies of the discharge cylinders 34 are hinged to the lower ends of the vertical brackets 31a, and the free ends of the piston rods of the two discharge cylinders 34 are hinged to the middle of the back of the corresponding discharge door 33. Valve body assemblies 40 are fixed to the two vertical brackets 31a, and the discharge cylinders 34 are controlled by the air circuit to perform the required actions.

[0053] The free ends of the two discharge doors 33 are symmetrically connected to a pair of discharge door support rods 33 b extending to the bottom of the middle frame 32 , and the bottom of each discharge door support rod 33 b supports a locking pin 37 .

[0054] The middle part of the middle frame 32 is hollowed out and the top is covered with a middle frame inspection panel 32b. By opening the middle frame inspection panel 32b, the locking pin driving mechanism below can be inspected, thus avoiding the need to set up an inspection channel in the pit, reducing the pit depth and reducing infrastructure investment.

[0055] A lock pin bracket 36 is provided below the middle frame inspection panel 32b. The lock pin bracket 36 includes two parallel U-shaped brackets 36a. Each lock pin 37 is respectively fixed to the end of the U-shaped bracket 36a. The axes of each lock pin are parallel to each other and extend along the width direction of the discharge door 33. The two U-shaped brackets 36a are connected as a whole by a transverse bracket 36b.

[0056] A vertical ear 36c extending upward is provided in the middle of the U-shaped bracket 36a on one side, a middle frame cross plate extending along the width direction of the middle frame is welded to one end of the middle frame 32, a cylinder ear 35a is fixedly connected to the lower middle part of the middle frame cross plate, the cylinder body of the locking pin driving cylinder 35 is hinged at the lower end of the cylinder ear 35a, the piston rod of the locking pin driving cylinder 35 extends along a horizontal line in the width direction of the door frame, and the free end of the piston rod is hinged to the upper end of the vertical ear 36c.

[0057] The free ends of the lock pins 37 are respectively inserted into the guide holes of the corresponding lock pin guide seats 38 , and the upper ends of the lock pin guide seats 38 on the same side are respectively fixed to the transverse connecting rods 39 , and the two ends of the transverse connecting rods 39 are respectively fixed to the door frame 31 .

[0058] The tops of both sides of the middle frame 32 are provided with chamfers, which guide the material into the door, increase the opening size of the upper end, and reduce the material accumulation area on the top of the middle frame. The bottoms of both sides of the middle frame 32 are respectively provided with middle frame sealing stops 32a; the free ends of the discharge door 33 are respectively provided with discharge door sealing folds 33c, which cover the top of the discharge door support rod 33b and extend horizontally to the bottom of the middle frame sealing stop 32a.

[0059] The lock pin driving cylinders 35 and the discharge cylinders 34 on both sides act synchronously, that is, the two discharge doors 33 are closed and opened synchronously, and the figure shows the open and closed states respectively for simplicity.

[0060] During unloading, as the material level or unloading point requirements increase, the piston rod of the lock pin driving cylinder 35 is extended by the valve body assembly 40, and the entire lock pin bracket 36 is driven to translate forward through the vertical support ear 36c, and the four lock pins 37 located at the end of the U-shaped bracket 36a are synchronously retracted into the lock pin guide seat 38, that is, withdrawn from under the corresponding unloading door support rod 33b; then the piston rod of the unloading cylinder 34 is retracted, and the unloading door 33 rotates downward around the door shaft 33a to open, and unloading begins.

[0061] After unloading is completed, when the piston rod of the unloading cylinder 34 extends out, the unloading door 33 rotates upward around the door shaft 33a and closes, the unloading door support rod 33b abuts against the bottom of the middle frame 32, and the unloading door sealing fold 33c reaches the bottom of the sealing stop 32a of the middle frame, forming a horizontal slit to achieve natural material sealing; then the piston rod of the locking pin driving cylinder 35 contracts, and drives the entire locking pin bracket 36 to translate in the opposite direction through the vertical support ear 36c, and the four locking pins 37 located at the end of the U-shaped bracket 36a simultaneously extend from the locking pin guide seat 38, and are laterally inserted into the bottom of the corresponding unloading door support rod 33b, abutting against the unloading door support rod 33b, and bearing the material load on the unloading door 33 after the warehouse is filled.

[0062] like Figures 17 to 21 As shown, the single cylinder unloader of the present invention comprises a door frame 41, a flap door 43, and a discharge cylinder 44. The door frame 41 covers the upper port of the pit, the short side of the door frame is supported on the stoppers on both sides of the pit, and the long side spans between the stoppers on both sides of the pit. The middle of the two long sides of the door frame 41 is connected by a middle frame 42, and the two short sides of the door frame 41 are respectively hinged with the flap door 43 through door shafts 43a. The door shafts 43a are provided with two coaxial lines and are respectively hinged on both sides of the flap door 43 in the width direction.

[0063] Thickened door shaft guide plates 45 are provided at the upper parts of both ends of the long sides of the door frame, and door shaft guide grooves 45a extending obliquely downward are provided on each door shaft guide plate 45. Door shafts 43a are hinged on both sides of the upper end of the flap door 43, and the outer ends of the door shafts 43a are respectively inserted into the corresponding door shaft guide grooves 45a, and the free ends of the two flap doors 43 are respectively extended obliquely to the bottom of the middle frame 42. Discharge cylinders are hinged at the lower parts of the two short sides of the door frame, and the free ends of the piston rods of the two discharge cylinders are respectively hinged at the middle of the back of the corresponding flap door 43.

[0064] Sliding guide plates 46 are fixed to the outer walls of the two long sides of the door frame, and guide grooves 46a are provided on the sliding guide plates 46. The guide grooves 46a extend downward along an arc line with the axis of the door shaft 43a when it is at the upper end of the door shaft guide groove 45a as the center, and a locking groove 46b is provided at the upper end of the guide groove 46a, which turns horizontally away from the unloading cylinder. Guide pins 43b extending outward are respectively connected to the middle of both sides of the flap door 43, and the inner ends of the guide pins 43b are fixed to the side edges of the flap door 43 by lock nuts 43b1, and the outer ends of the two guide pins 43b are respectively embedded in the corresponding guide grooves 46a.

[0065] In order to reduce the sliding resistance, a roller 43c can be fixed to the outer end of the guide pin 43b, and the roller 43c is embedded in the corresponding guide slot 46a. The outer end below the middle of the guide slot 46a is provided with a slot chamfer 46c to avoid dust or material accumulation at the lower edge of the guide slot 46a, so that the roller 43c will not be blocked.

[0066] The free ends of the two flap doors 43 extend obliquely downward from the middle frame 42, and the angle between the top surface of the flap door 43 and the horizontal plane is 14° to 18°; in this way, a larger opening angle can be obtained after the flap door 43 is opened, usually up to 58° to 60°, making unloading smoother and faster.

[0067] The tops of both sides of the middle frame 42 are provided with chamfers, which guide the material into the door, increase the opening size of the upper end, and reduce the material accumulation area at the top of the middle frame. The bottoms of both sides of the middle frame 42 are respectively provided with middle frame sealing stops 42a; the free ends of the flap door 43 are respectively provided with flap door sealing material folding edges 43d. When the flap door 43 is closed and its free end abuts against the bottom of the middle frame 42, the flap door sealing material folding edge 43d is located below the middle frame sealing stop 42a, forming a transverse slit to achieve natural material sealing.

[0068] Door side baffles 41a are provided above the gaps between the two sides of the flap door 43 and the door frame 41 after closing to prevent material leakage on both sides. The door side baffles 41a are formed by bending a thin plate, and the facing end faces are triangular. The upper end is bent outward and fixedly connected to the upper edge of the door frame 41, and the lower end is open.

[0069] The discharge cylinders 44 on both sides act synchronously, that is, the two flap doors 43 close and open synchronously, and the figure shows the open and closed states respectively for simplicity.

[0070] When the flap door 43 is in a fully open state, the door shaft 43a is located at the upper end of the door shaft guide groove 45a, and the roller 43c is located at the lower end of the guide groove 46a. Before loading, the flap door 43 is closed. Under the control of the valve assembly 48, the piston rod of the discharge cylinder 44 extends, and the flap door 43 rotates upward around the door shaft 43a. At the same time, the roller 43c moves upward along the guide groove 46a. When it reaches the upper end of the guide groove 46a, the flap door 43 slides forward for a distance under the push of the discharge cylinder 44, so that the roller 43c slides into the locking groove 46b. At this time, the door shaft 43a is located at the lower end of the door shaft guide groove 45a, and the flap door 43 enters a self-locking state. The gravity of the material carried by the flap door 43 will not generate a component force that causes the flap door 43 to slide upward, so the roller 43c will not automatically slide into the guide groove 46a, and the self-locking is very reliable. The horizontal section of the lower edge of the locking groove 46b bears the material pressure, and the unloading cylinder 44 does not need to bear the pressure generated by the material.

[0071] During unloading, as the material level or unloading point requirements increase, the piston rod of the unloading cylinder 44 contracts, first pulling the flap door 43 backward for a distance, causing the roller 43c to slide out of the locking groove 46b and enter the upper end of the guide groove 46a. At this time, the door shaft 43a returns to the upper end of the door shaft guide groove 45a. As the piston rod of the unloading cylinder 44 continues to contract, the flap door 43 rotates downward around the door shaft 43a and opens, and unloading begins. When the roller 43c slides to the lower end of the guide groove 46a, the flap door 43 reaches the maximum opening angle.

[0072] A rotating baffle plate 47 covering the inner port of the guide slot 46a is provided on both sides of the flap door 43, and the rotating baffle plate 47 is attached to the inner wall of the long side of the door frame 41; the rotating baffle plate 47 is semicircular, and when the flap door 43 is in a closed state, the bottom horizontal side of the rotating baffle plate 47 is parallel to the lower edge of the long side of the door frame, the arc-shaped top faces upward, and the baffle plate guide pin hole 47a is located below the arc-shaped top.

[0073] The guide pin 43b passes through the baffle plate guide pin hole 47a at the upper part of the rotating baffle plate 47. The lower part of the rotating baffle plate 47 is provided with a baffle plate waist-shaped groove 47b, which extends obliquely downward. A baffle plate rotating pin 47c is embedded in the baffle plate waist-shaped groove 47b. The baffle plate rotating pin 47c is fixed on the long side of the door frame to form two-point positioning for the rotating baffle plate 47. The baffle plate rotating pin 47c is in a step shape with a thick inner part and a thin outer part, and the thinner outer end extends from the small hole on the long side of the door frame. The outer end is embedded with a shaft retaining ring for axial positioning.

[0074] When the flap door 43 is in a closed state, the guide pin 43b is located at a high position, that is, the roller 43c is located in the locking groove 46b, the baffle plate rotating pin 47c is close to one end of the baffle plate waist-shaped groove 47b, and the rotating baffle plate 47 horizontally blocks the inner port of the guide slide groove 46a.

[0075] When the flap door 43 is in the open state, the guide pin 43b is located at a low position, that is, the roller 43c is located at the lower end of the guide chute 46a, and the baffle plate rotating pin 47c is located at the other end of the baffle plate waist-shaped groove 47b, and the baffle plate vertically blocks the inner end of the guide chute 46a. In this way, when the material is opened and closed, the rotating baffle plate 47 can block the inner end of the guide chute 46a, which can prevent material leakage and prevent material from being retained at the lower edge of the guide chute 46a, ensuring that the roller 43c slides smoothly along the guide chute 46a.
