Description

Technical Field

[0001] The invention relates to the technical field of stone crushing devices, in particular to a stone crushing device for a construction water conservancy project. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. Water is a valuable resource that is indispensable to human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods and waterlogging disasters, and regulate and distribute water to meet people's needs for water resources in life and production. Water conservancy projects require the construction of different types of hydraulic structures such as dams, spillways, sluices, water inlets, channels, ferries, rafts and fishways to achieve their goals.

[0003] In the Chinese patent authorization number CN117483077B, the patent solves the problem that during the use of the prior art, the crushed stones directly fall on the unloading plate, and the unloading is carried out through the unloading plate. The crushed stones are not buffered when falling. The unloading plate is damaged due to the excessive impact of the crushed stones, which shortens the service life of the unloading plate and is inconvenient for subsequent use. In this patented technology, the stones are first crushed, and then the crushed stones are discharged and finally fall on the unloading plate. Then, the crushed stones pass through the unloading plate, which will cause the unloading plate to rise and fall. When the unloading plate rises and falls, the gear is driven to rotate during the descending process of the unloading plate, and the gear then drives the rack to rise, so that The two support blocks rise up, and the two support blocks are used to contact with the bottom of the feed plate during the process of receiving the material to stabilize it. However, in the process of crushing stones, the crushing roller directly breaks the stones, and it is difficult to adjust the size of the stones. The crushed stones are all discharged uniformly and fall on the feed plate. The impact force on the feed plate is different. When the larger stones fall and contact the feed plate, the bottom of the feed plate and the support blocks are directly contacted in advance. At this time, the feed plate is limited by the support blocks and cannot play a buffering role. Smaller stones still hit the feed plate. Therefore, there is still a probability that the feed plate will be damaged by crushed stones during long-term use. For this reason, we propose a stone crushing device for construction water conservancy projects. Summary of the invention

[0004] The purpose of the present invention is to provide a stone crushing device for construction water conservancy engineering to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a stone crushing device for construction water conservancy engineering, comprising a casing, a feed port is arranged on the top of the casing, discharge ports are arranged on both sides of the casing, a pair of crushing rollers are installed inside the casing, a bearing is fixedly installed at one end of each crushing roller, the bearing is fixedly connected to the casing, anti-fouling covers are fixedly installed at the corners around the middle part of the casing, a mounting plate is fixedly installed on the casing near the bottom of each anti-fouling cover, a first spring is fixedly connected to one side of the mounting plate, a traction nozzle is fixedly installed on one end of each of the first springs, a plurality of traction nozzles are fixedly installed on a common end of a leakage plate, a plurality of drop holes are arranged on the leakage plate, and the plurality of drop holes are divided into Multiple groups are arranged in a ring shape, and the sizes of the multiple groups of ring-shaped blanking holes are gradually reduced from the axis of the leak plate to its edge. A first discharge plate is fixedly installed at the bottom of the casing, and a second discharge plate is fixedly installed on the first discharge plate. The first discharge plate and the second discharge plate are staggered and their ends are in contact with the discharge ports on both sides of the casing. The bottom of the leak plate has a downward depression so that the top of the leak plate forms an inclined surface converging to the axis of the leak plate. Limit seats are fixedly installed on all four sides of the interior of the casing through fixed plates, and each of the limit seats is buckled on one of the blanking holes. The bottom of the leak plate is close to the intersection of the first discharge plate and the second discharge plate, and the intersection of the first discharge plate and the second discharge plate forms a distribution port for discharging gravel to the discharge port.

[0006] Preferably, a support platform is fixedly installed in the middle of the casing near the top of the leak plate, baffles are fixedly installed on both sides of the top of the support platform, and cleaning brushes are fixedly installed between the opposite surfaces of the two baffles, and the cleaning brushes are in contact with the crushing roller.

[0007] Preferably, the bottom of the casing is rotatably connected to a rotating rod, the rotating rod is slidably connected to a lifting rod, an extension rod is fixedly installed on the top of the lifting rod, the top of the extension rod is fixedly connected to a diverter plate, and the diverter plate is arranged next to the bottom of the support platform.

[0008] Preferably, a mushroom top plate is fixedly installed on the top of the diverter plate, and the top of the mushroom top plate corresponds to between the two crushing rollers. The outer ring of the bottom of the diverter plate is slidably connected to a lifting column, and a pair of fixed legs are provided at the bottom of the lifting column. The two fixed legs are respectively fixedly installed on the first unloading plate and the second unloading plate. Second springs are provided at both upper and lower ends of the lifting column, the top of the second spring is connected to the diverter plate, and the bottom of the second spring is fixedly connected to a moving plate, the moving plate is slidably connected to the extension rod, the bottom end of the second spring is connected to the lifting column, and the top is fixedly connected to a lifting plate.

The transmission gears and the racks are meshed for transmission, and a support foot is fixedly connected between each side of the transmission gear and the leaking plate.

[0010] Preferably, the lifting column is in contact with the middle of the leak plate. When the mushroom top plate is subjected to the force of falling rocks, the diverter plate descends to compress the second spring, so that the lifting plate descends and drives the rack to drive the transmission gear to rotate, separating the inner circle of the leak plate and the lifting column.

[0011] Preferably, a third pulley is sleeved on the bottom of the rotating rod, one end of one of the crushing rollers is fixedly mounted with a first gear, and another end of the crushing roller is fixedly connected to a second gear, one side of the casing is rotatably connected to a pair of transition gears that mesh with each other, a pair of the transition gears are located between the first gear and the second gear and mesh with each other, a first pulley is fixedly sleeved on one side of the first gear, a second pulley is sleeved on a rotating shaft at one end of the first pulley, and one end of the second pulley and the third pulley are respectively sleeved with helical gears, and the two helical gears are meshed together.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] When the crushed stones fall on the leaking plate, the first spring generates a tensile deformation, and when the multiple traction nozzles located at the edge of the leaking plate are lowered from the leaking plate, the leaking plate is stabilized and the first spring generates a buffer for the leaking plate. After the leaking plate is deformed, the size of each corresponding drop hole is also changed. The top of the leaking plate has an inclined surface that converges toward the axis of the leaking plate. When the size of the drop hole changes, the crushed stone particles with smaller sizes close to the edge of the leaking plate can preferentially fall along the drop hole to the first and second discharge plates below, while the crushed stones with larger sizes roll toward the axis through the edge of the leaking plate, and the crushed stones of different sizes are graded and fall onto the first and second discharge plates to discharge energy to the leaking plates, thereby preventing the leaking plates from being damaged.

[0015] Larger and smaller sized gravel can contact the mushroom top plate during the falling process, generating pressure on the mushroom top plate. After the mushroom top plate generates pressure, the outer ring of the bottom of the diverter plate drops, and then the two second springs are compressed after being stressed, causing the position of the lifting plate to drop. In the process of the lifting plate descending, multiple racks are driven to descend. Since the racks are meshed with the transmission gears, in the process of the rack descending, the transmission gears drive the support legs to move away from the lifting columns, and the ends of the support legs are connected to the middle part of the leak plate, so that the middle part of the leak plate opens and deforms, so that the gravel with larger particle size near the edge of the lifting column is discharged to the first unloading plate and the second unloading plate, so as to prevent the accumulation of gravel on the leak plates, which will cause the leak plates to discharge poorly and reduce the failure rate of the device.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-10The present invention provides a technical solution: a stone crushing device for construction water conservancy engineering, comprising a casing 1, a feeding port is arranged on the top of the casing 1, and discharge ports are arranged on both sides of the casing 1, a pair of crushing rollers 8 are installed inside the casing 1, a bearing 801 is fixedly installed at one end of each crushing roller 8, and the bearing 801 is fixedly connected to the casing 1, and anti-fouling covers 10 are fixedly installed at the corners around the middle of the casing 1, and a mounting plate 13 is fixedly installed on the casing 1 near the bottom of each anti-fouling cover 10, a first spring 14 is fixedly connected to one side of the mounting plate 13, and a traction nozzle 11 is fixedly installed on one end of each of the first springs 14, and a plurality of traction nozzles 11 are fixedly installed on a common end of a leakage plate 12, and a plurality of drop holes 1201 are opened on the leakage plate 12, and the plurality of drop holes 1201 are divided into a plurality of groups and the plurality of groups are surrounded in a ring shape, and the plurality of groups of ring-shaped drop holes 1201 are sized. The size gradually decreases from the axis of the leak plate 12 to its edge, and a first discharge plate 17 is fixedly installed at the bottom of the casing 1, and a second discharge plate 18 is fixedly installed on the first discharge plate 17, and the first discharge plate 17 and the second discharge plate 18 are in a staggered state and the ends are in contact with the discharge ports on both sides of the casing 1; the material of the leak plate 12 is made of soft rubber, and the traction nozzle 11 and the leak plate 12 are fixedly connected together by bolts; the bottom of the leak plate 12 has a downward depression, so that the top of the leak plate 12 forms an inclined surface converging to the axis of the leak plate 12, and the inner periphery of the casing 1 is fixedly installed with a limited seat 1202 by a fixed plate, and each of the limited seats 1202 is buckled on one of the drop holes 1201; the bottom of the leak plate 12 is close to the intersection of the first discharge plate 17 and the second discharge plate 18, and the intersection of the first discharge plate 17 and the second discharge plate 18 forms a distribution port for discharging crushed stones to the discharge port;First, the stones generated by the water conservancy project are put into the feed port at the top of the casing 1, and then the stones are crushed between a pair of crushing rollers 8. Since the gap between the pair of crushing rollers 8 is fixed, the crushing efficiency of the outer ring of each crushing roller 8 is equal. There may be crushed stones with relatively small particle sizes mixed together between the stones put in, and then the stones crushed by the crushing rollers are divided into crushed stones of different particle sizes. After being processed by the crushing rollers 8, they fall on the leak plate 12. The crushed stones have a certain gravity to fall to the leak plate 12. The leak plate 12 is used to disperse or buffer the energy generated by the crushed stones. When the crushed stones fall on the leak plate 12, the leak plate 12 produces The first spring 14 generates a tensile deformation, and the multiple traction nozzles 11 located at the edge of the leak plate 12 generate stability for the leak plate 12 when the leak plate 12 descends, and the first spring 14 generates a buffer for the leak plate 12. After the leak plate 12 is deformed, the size of each corresponding drop hole 1201 is also changed. The top of the leak plate 12 has an inclined surface that converges toward the axis of the leak plate 12. When the size of the drop hole 1201 changes, the smaller crushed stone particles close to the edge of the leak plate 12 preferentially fall along the drop hole 1201 to the first discharge plate 17 and the second discharge plate 18 below, while the larger crushed stone passes through the leak plate 12. The edge of the plate 12 rolls toward the axis, and the crushed stones of different sizes are graded and also fall onto the first discharge plate 17 and the second discharge plate 18 to prevent the top of the plate 12 from accumulating too much crushed stones and bearing too much weight to cause damage. The crushed stones are then separated for the second time through the first discharge plate 17 and the second discharge plate 18. The fallen crushed stones roll through the inclined surfaces of the first discharge plate 17 and the second discharge plate 18. The edge of the plate 12 is shorter than the top of the inclined surfaces of the first discharge plate 17 and the second discharge plate 18. The smaller crushed stones will be discharged preferentially to the first discharge plate 17 and the second discharge plate 18 at the edge of the plate 12, and then discharged to the bottom. The larger crushed stones need to be separated to a certain extent. The crushed stones roll, then pass through the first discharge plate 17 and the second discharge plate 18 and fall to the bottom of the casing 1, while the larger crushed stones cannot pass through the first discharge plate 17 and the second discharge plate 18, and fall on the material distribution port between the first discharge plate 17 and the second discharge plate 18 after rolling, and finally roll again at one end of the first discharge plate 17 and the second discharge plate 18 and are discharged at the discharge ports on both sides of the casing 1. When the device is installed, multiple recycling troughs (not shown) for recycling crushed stones can be installed at the bottom of the casing 1 to recycle crushed stone dust or crushed stones of different sizes. After recycling, the crushed stones can be used in other construction projects. ;

[0029] Furthermore, a support platform 9 is fixedly installed in the middle part of the casing 1 near the top of the leak plate 12, and baffles 15 are fixedly installed on both sides of the top of the support platform 9. A cleaning brush 16 is fixedly installed between the opposite surfaces of the two baffles 15. The cleaning brushes 16 are in contact with the crushing roller 8. Since there is a gap between a pair of crushing rollers 8, it is necessary to clean the outer ring of the crushing roller 8 when it rolls to prevent the outer ring of the crushing roller 8 from being stuck with gravel, thereby reducing the crushing efficiency.

[0030] Furthermore, a rotating rod 24 is rotatably connected to the bottom of the casing 1, and a lifting rod 23 is slidably connected to the rotating rod 24. An extension rod 25 is fixedly installed on the top of the lifting rod 23, and a diverter plate 19 is fixedly connected to the top of the extension rod 25. The diverter plate 19 is arranged next to the bottom of the support platform 9; a mushroom top plate 20 is fixedly installed on the top of the diverter plate 19, and the top of the mushroom top plate 20 corresponds to between the two crushing rollers 8. A lifting column 21 is slidably connected to the outer ring of the bottom of the diverter plate 19, and a pair of fixed legs 2101 are provided at the bottom of the lifting column 21. The two fixed legs 2101 are respectively fixedly installed on the first unloading plate 17 and the second unloading plate 18. The lifting column 21 is provided with a A second spring 26 is arranged, the top of the second spring 26 at the top is connected to the diverter plate 19, the bottom of the second spring 26 at the top is fixedly connected to a moving plate 27, the moving plate 27 is slidably connected to the extension rod 25, the bottom of the second spring 26 at the bottom is connected to the lifting column 21, and the top is fixedly connected to a lifting plate 28; the lifting plate 28 is rotatably connected to the lifting rod 23, a plurality of racks 29 are arranged on the outer ring of the lifting plate 28, the lifting column 21 is rotatably connected to the inside of the lifting column 21, the transmission gear 30 and the rack 29 are meshed for transmission, and a support foot 22 is fixedly connected between the side of each transmission gear 30 and the leaking plate 12; the lifting column 21 is in contact with the middle of the leaking plate 12; when the mushroom top After the plate 20 is subjected to the force of falling rocks, the diverter plate 19 descends and compresses the second spring 26 to descend, so that the lifting plate 28 descends and drives the rack 29 to drive the transmission gear 30 to rotate, and separates the inner circle of the plate 12 and the lifting column 21; the diverter plate 19 is designed to be rotatable. When a pair of crushing rollers 8 produce falling rocks, the diverter plate 19 receives all the rocks and can rotate to throw the rocks onto the plate 12 after centrifugal separation. The diverter plate 19 is above the plate 12. When rotating, it effectively reduces the impact damage of the rocks on the plate 12, reduces the density of the accumulated rocks, and improves the discharge efficiency of the plate 12. At the same time, the larger and smaller rocks can contact the mushroom top plate 20 on the way of falling, which is conducive to the mushroom top plate 20 generates pressure. After the mushroom top plate 20 generates pressure, the outer circle at the bottom of the diverter plate 19 descends, and then the two second springs 26 are compressed after being stressed, so that the position of the lifting plate 28 descends, and in the process of the lifting plate 28 descending, multiple racks 29 are driven to descend. Since the racks 29 are meshed with the transmission gears 30, in the process of the racks 29 descending, the transmission gears 30 drive the legs 22 to move away from the lifting column 21, and the ends of the legs 22 are connected to the middle part of the leak plate 12, so that the middle part of the leak plate 12 is opened and deformed, so that the larger particle size gravel near the edge of the lifting column 21 is discharged to the first unloading plate 17 and the second unloading plate 18, so as to prevent the accumulation of gravel on the leak plate 12, thereby causing the leak plate 12 to discharge poorly and reduce the failure rate of the device.

[0031] Specifically, a third pulley 4 is sleeved at the bottom of the rotating rod 24, one end of one of the crushing rollers 8 is fixedly installed with a first gear 5, and another end of the crushing roller 8 is fixedly connected to a second gear 7, one side of the casing 1 is rotatably connected to a pair of transition gears 6 that mesh with each other, and the pair of transition gears 6 are located between the first gear 5 and the second gear 7 and mesh with each other. A first pulley 2 is fixedly sleeved on one side of the first gear 5, and a second pulley 3 is sleeved on a rotating shaft at one end of the first pulley 2. The second pulley 3 and the third pulley 4 are respectively sleeved with a bevel gear 301 at one end, and the two bevel gears 301 are meshed together. First, a motor is installed at either end of the second pulley 3 to drive the second pulley 3 to rotate. The second pulley 3 drives the first pulley 2 to rotate during the rotation process, and when the first pulley 2 rotates, it drives the first gear 5 to rotate. The rotation of the first gear 5 drives a pair of transition gears 6 to rotate, and then one of the transition gears 6 drives the second gear 7 to rotate, so that a pair of crushing rollers 8 rotate in the opposite direction, and at the same time a pair of meshing helical gears 301 drives the third pulley 4 to rotate. When the third pulley 4 rotates, it drives the rotating rod 24 to rotate, and the rotating rod 24 and the lifting rod 23 are connected to each other. The rotation of the lifting rod 23 causes the extension rod 25 to drive the diverter plate 19 to rotate, and the diverter plate 19 and the pair of crushing rollers 8 rotate synchronously. The equipment structure is highly correlated, which effectively improves the recovery rate of crushed stone.
