Description

Technical Field

[0001] The invention belongs to the technical field of construction waste crushing, and more specifically, particularly relates to a crushing device used in building construction projects. Background Art

[0002] In construction projects, crushing equipment is an important tool for handling construction waste. Crushing equipment for handling construction waste generally consists of three main parts: a crushing part, a conveying part, and a support part. The crushing part is used to crush construction waste, the conveying part is used to convey construction waste, and the support part is used to maintain the stability of the conveying part and the crushing part. However, there are some problems in the use of existing crushing equipment for construction projects.

[0003] 1. The installation position and angle of the conveying structure of existing crushing equipment are usually fixed. When the driving equipment on the conveying structure needs to be inspected and repaired, the workers have to climb to a high place to perform the operation because the position of the conveying structure cannot be flexibly adjusted. This is not only extremely inconvenient during the operation, but also poses a great safety risk. For example, workers may fall due to unstable standing, or be injured due to improper use of tools when working at height. In addition, the working environment at height is not conducive to comprehensive and detailed inspection and maintenance of the equipment, which may result in some potential problems not being discovered and solved in time.

[0004] 2. The existing crushing equipment cannot be effectively adjusted due to its conveying structure and overall structure, resulting in a high center of gravity and extremely poor stability during transportation. When the road conditions are poor or there are bumps during transportation, the equipment is prone to shaking or even tipping over, causing equipment damage and safety accidents. Moreover, due to the fixed structure, the overall height and volume of the equipment cannot be effectively reduced, which makes the transportation process restricted by factors such as road height and width restrictions, increasing the difficulty and cost of transportation.

[0005] 3. The conveying structure of traditional crushing equipment has a relatively single function. In most cases, it can only convey the crushed construction waste from the crusher. When it is necessary to convey the uncrushed construction waste into the crusher, the existing conveying structure is often not competent. This functional limitation greatly limits the applicability of crushing equipment in different construction scenarios and needs. In some construction sites with limited space, traditional crushing equipment cannot flexibly change the conveying direction and function, and cannot meet the requirements of actual construction, thus affecting construction efficiency and project progress.

[0006] To sum up, in order to improve the convenience, stability and applicability of crushing equipment during maintenance, transportation and use, it is necessary to improve and innovate the existing crushing equipment. Summary of the invention

[0016] In the present invention, the operator can quickly lower the height of the conveying structure and inspect the driving equipment of the conveying structure on the ground without climbing to a high place or disassembling the conveying structure and the supporting structure, thereby improving the convenience and safety of maintenance.

[0017] In the present invention, the moving rollers on the moving frame are driven to continuously lower their height through the deflection of the long rod, so that the right side of the conveying structure is continuously lowered until the conveying structure is in a horizontal state.

[0019] In the present invention, the conveying structure can be used to convey the crushed construction waste to a higher place for transportation, and can also be used to convey the uncrushed construction waste into the crusher, which further improves the applicability and the adjustment method is simple and quick.

[0020] In the present invention, when the conveying structure is used to convey uncrushed construction waste into the crusher and the driving device needs to be inspected and repaired, after the positioning screw 1 is pulled out, the supporting structure can be moved to drive the rotating rod to move left until the thick end of the right side of the rotating rod is supported, and then the positioning screw 1 is inserted into the circular groove 3 on the rotating rod. At this time, the conveying structure and the supporting structure can be deflected, and then the height of the driving device can be lowered, which can effectively prevent the deflection of the conveying structure from being blocked by the crusher. The deflected conveying structure and the supporting structure can obtain a wider operating space. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The three pairs of cross beams 37 between the long frame 3 and the middle frame 9 are all threadedly sleeved with switching screws 36, the two rails 39 are both slide rails with concave upper surfaces, and the two rails 39 are provided with two strip grooves 41, the upper ends of the two middle frames 9 are both installed with connecting rods 34, and the connecting rod 21 between the two short frames 16 is fixedly connected with two support columns 38, wherein the upper ends of the two middle frames 9 are rotatably connected to the middle part of the conveying structure 2 through the connecting rod 34, and the adjustment mechanism includes two moving frames 45 and two long rods 42, and the two moving frames 45 are connected to the middle part of the conveying structure 2. The movable frame 45 is rotatably connected to two moving rollers 44, and a connecting frame 46 is fixedly connected between the two moving frames 45. The two ends of the connecting frame 46 are rotatably connected to the upper ends of the two long rods 42, wherein the lower ends of the two long rods 42 are rotatably connected to the bottom rod 47, and the two ends of the bottom rod 47 are rotatably connected to rectangular members 49, and the two ends of the bottom rod 47 are also rotatably sleeved with rolling sleeves 48, and the two rectangular members 49 are fixedly connected to the gripping rods 50, and the bottom surfaces of the two gripping rods 50 are provided with bottom grooves 51, and the middle parts of the two long rods 42 are provided with limited The two bottom grooves 51 are rotatably mounted with vertical rods 52, and the two long frames 3 are provided with vertical grooves 35. The long frame 3 is an inner concave frame, and the end of the moving roller 44 is a thick end, which is stuck in the inner groove of the long frame 3, and the roller body of the moving roller 44 is sleeved in the vertical groove 35. When it is necessary to use the conveying structure 2 to convey the construction waste to be crushed into the crusher, the limiting member 26 can be rotated to disengage the positioning rod 5, and the positioning rod 5 can be pulled out, so that the conveying structure 2 and the supporting structure are separated from the fixed frame 7. At this time, the mobile conveying structure 2 and the supporting structure are separated from the fixed frame 7. The support structure is moved to the left side of the fixed frame 7, and the rotating rod 30 is inserted into the rod groove 11 and then rotatably connected with the positioning rod 2 4. The positioning screw 10 is inserted into the circular groove 3 29 in the middle, and the positioning screw 4 22 is inserted into the circular groove 3 29 on the left side, so that the raised right end of the conveying structure 2 is aligned with its feeding structure 8 and maintains a stable position, so that the conveying structure 2 can be used to convey the crushed construction waste to a higher place for transportation, and can also be used to convey the uncrushed construction waste into the crusher, which further improves the applicability and the adjustment method is simple and quick.

[0046] Working principle: A crushing device used in construction projects. The construction waste to be crushed enters the crusher body 6 from the feeding structure 8 for crushing. After crushing, it is discharged from the discharge port of the crusher body 6. The crushed construction waste is thrown through the conveying structure 2 for easy loading and transportation. When the equipment is in Figure 1 The state is a normal working state, the two positioning rods 1 5 are respectively inserted into the two rod grooves 2 14, the positioning screw 3 19 on the short frame 16 is inserted into the rightmost circular groove 27, and the two positioning screws 2 15 are respectively inserted into the two circular grooves 1 28 on the right side. At this time, the crushed material discharged from the discharge port falls onto the conveyor belt surface of the conveying structure 2 for conveying;

[0047] Three sets of universal wheels are installed at the bottom of the chassis 1. When the state of the conveying structure 2 needs to be adjusted, the positioning screw rod 15 is rotated to release the limit of the positioning rod 5. At this time, the universal wheels are used to move the entire conveying structure 2 and the supporting structure until the limit piece 26 on the positioning rod 5 abuts against the fixing frame 7, and the positioning screw rod 15 is reset to be inserted into the circular groove 28 on the left side. At this time, the conveying structure 2 and the supporting structure reach the adjustment state, and the deflection of the conveying structure 2 is not interfered by the crusher body 6;

[0048] When the driving device on the conveying structure 2 needs to be repaired, two operators hold the two gripping rods 50 respectively, and move the vertical rod 52 to make the vertical rod 52 disengage from the rightmost limit plate 40. At this time, the operator holds the gripping rod 50 and moves it to the left continuously. The roller sleeve 48 is stuck in the groove of the track 39, and the rectangular member 49 is stuck in the strip groove 41. As the gripping rod 50 moves to the left, the moving roller 44 on the moving frame 45 is driven to continuously decrease in height through the deflection of the long rod 42, so that the right side of the conveying structure 2 is continuously decreased in height. Since the conveying structure 2 is rotatably installed on the two middle frames 9 to form a structure similar to a seesaw, the right side of the conveying structure 2 is higher than the left side. The conveying structure 2 is slightly heavy, and the force required to support the right side when maintaining balance is within the strength of the two operators. When the right side of the conveying structure 2 drops to contact the buffer sleeve 20, it drops with the buffer sleeve 20 until it contacts the fixed rod 24. At this time, the vertical rod 52 is released, and the vertical rod 52 is stuck between the two limiting pieces 40 on the leftmost side, which plays a preliminary limiting effect. At this time, the limiting groove 43 on the long rod 42 is aligned with the switching screw 36 on the lowest crossbeam 37, and the switching screw 36 on the lowest crossbeam 37 is rotated to insert it into the limiting groove 43, which plays a second limiting effect, thereby improving the stability during maintenance. The state at this time is as follows Figure 2 As shown, in the maintenance state, the operator can perform maintenance on the driving equipment of the conveying structure 2 on the ground without climbing to a high place or disassembling the conveying structure 2 and the supporting structure, thereby improving the convenience and safety of maintenance;

[0049] When transportation is required, the gripping rod 50 is moved in the same steps, and the moving roller 44 on the moving frame 45 is driven to continuously descend in height through the deflection of the long rod 42, so that the right side of the conveying structure 2 is continuously lowered in height until the conveying structure 2 is in a horizontal state. At this time, the vertical rod 52 is loosened to make it fit between the two middle limiting pieces 40, which plays a preliminary limiting effect. At this time, the limiting groove 43 on the long rod 42 is aligned with the switching screw 36 on the middle cross beam 37, and the switching screw 36 is rotated to be inserted into the limiting groove 43, which plays a second limiting effect, thereby improving the stability during transportation. The state at this time is as follows Figure 3 As shown, the overall height of the conveying structure 2 and the supporting structure is reduced, that is, the overall center of gravity is lowered. The lowered center of gravity will improve stability and safety during transportation and facilitate transfer and movement;

[0050] The conveying structure 2 and the supporting structure can be quickly switched to the maintenance state, the transfer state and the normal working state by continuously changing the position of the adjustment mechanism, and the stability is ensured by double limit, which greatly improves the applicability of the whole equipment;

[0051] like Figure 4 As shown, when it is necessary to use the conveying structure 2 to convey the construction waste to be crushed into the crusher, the limiter 26 can be rotated to disengage the positioning rod 15, and the positioning rod 15 can be pulled out, so that the conveying structure 2 and the supporting structure are completely separated from the fixed frame 7. At this time, the conveying structure 2 and the supporting structure are moved to the left side of the fixed frame 7, and the rotating rod 30 is inserted into the rod groove 11 and then rotatably connected with the positioning rod 24, and the positioning screw 10 is inserted into the circular groove 3 29 in the middle, and the positioning screw 4 22 is inserted into the circular groove 3 29 on the left side, so that the raised right end of the conveying structure 2 is aligned with the feeding structure 8 and keeps the position stable, so that the conveying structure 2 can be used to convey the crushed construction waste to a high place for transportation, and can also be used to convey the uncrushed construction waste into the crusher, which further improves the applicability, and the adjustment method is simple and fast;

[0052] When the conveying structure 2 is used to convey the uncrushed construction waste into the crusher and the driving device needs to be repaired, after the positioning screw 10 is pulled out, the supporting structure can be moved to drive the rotating rod 30 to move to the left until the thick end of the right side of the rotating rod 30 is supported, and then the positioning screw 10 is inserted into the circular groove 3 29 on the rotating rod 30. At this time, the conveying structure 2 and the supporting structure can be deflected, and then the height of the driving device can be lowered, which can effectively prevent the deflection of the conveying structure 2 from being blocked by the crusher. The deflected conveying structure 2 and the supporting structure can obtain a wider operating space.

Many modifications and variations will be apparent to those of ordinary skill in the art.
