Description

Technical Field

[0001] The utility model relates to the technical field of sludge scrapers, and particularly relates to a blade structure of a sludge scraper with adjustable sludge scraping angle. Background Technique

[0002] In many industrial and environmental protection fields, sludge scrapers are commonly used equipment for removing sediments at the bottom of facilities such as sedimentation tanks. The blade structure of the sludge scraper plays a crucial role in its sludge scraping effect and working efficiency.

[0003] The scraping angle of the traditional sludge scraper blade structure is fixed and non-adjustable, which may result in the inability to achieve the best sludge scraping effect in different working scenarios and sediment conditions; in addition, the installation stability of the existing sludge scraper blade structure is poor, resulting in poor use effects. Therefore, we introduce a blade structure of a sludge scraper with adjustable sludge scraping angle. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a blade structure of a sludge scraper with adjustable sludge scraping angle, which can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A blade structure of a sludge scraper with adjustable sludge scraping angle includes a mounting plate. The left end of the mounting plate is fixedly connected with a right fixing component. The rear part of the outer surface of the right fixing component is movably installed with a left fixing component through a hinge. The right fixing component and the left fixing component have the same structure and are distributed symmetrically left and right. Two bolts are threadedly connected to the upper and lower parts of the left end of the left fixing component respectively. Nuts are threadedly connected to the right parts of the outer surfaces of the two bolts respectively. A connecting component is fixedly connected to the upper part of the right end of the mounting plate, and an adjusting component is fixedly connected to the lower part of the right end of the mounting plate.

[0007] The adjusting component includes a fixed head. The front inner wall surface and the rear inner wall surface of the fixed head are jointly movably installed with a mounting block through bearings. The right end of the mounting block is fixedly connected with an adjusting plate. A slider is movably sleeved on the adjusting plate. The upper end of the slider is fixedly connected with a fixed block. A third screw hole is opened at the upper end of the fixed block. The lower end of the adjusting plate is fixedly connected with a blade body. The left end of the fixed head is fixedly connected with the right end of the mounting plate.

[0008] Preferably, there is a gap between the outer surface of the mounting block and the inner wall surface of the fixed head.

[0009] By adopting the above technical solution: the existence of the gap reduces the frictional resistance between the mounting block and the inner wall surface of the fixed head when the mounting block rotates, enabling the mounting block to adjust the angle more smoothly and easily, and the operation is more convenient and labor-saving.

[0010] Preferably, the connecting component includes a connecting plate and a screw rod. A plurality of second screw holes penetrating up and down are formed in the upper end of the connecting plate. A knob is fixedly connected to the upper end of the screw rod. A plurality of anti-slip grooves are formed on the outer surface of the knob. The left end of the connecting plate is fixedly connected to the right end of the mounting plate.

[0011] By adopting the above technical solution: the design of multiple second screw holes on the connecting plate enables the selection of different screw holes for connection according to actual needs, increasing the flexibility and adaptability of adjustment.

[0012] Preferably, the outer surface of the screw rod is threadedly connected to the inner wall surfaces of the corresponding second screw holes and the third screw holes.

[0013] By adopting the above technical solution: the threaded connection has a self-locking characteristic to a certain extent, which can prevent accidental angle changes caused by vibration or other factors during the working process and maintain the stability of the sludge scraping angle.

[0014] Preferably, the left fixing component includes a fixing ring. An anti-slip pad is fixedly connected to the inner wall surface of the fixing ring. A plurality of anti-slip strips are fixedly connected to the inner wall surface of the anti-slip pad. A fixing plate is fixedly connected to the front part of the outer surface of the fixing ring. First screw holes penetrating left and right are formed in the upper left part and the lower left part of the fixing plate. The outer surface of the fixing ring is movably connected to the outer surface of the right fixing component through a hinge.

[0015] By adopting the above technical solution: the anti-slip pad and the anti-slip strips increase the friction with the installation part, effectively preventing sliding or displacement during the working process and making the sludge scraper work more reliably.

[0016] Preferably, the fixing ring and the anti-slip pad are both semicircular. The inner wall surfaces of the two first screw holes are respectively threadedly connected to the outer surfaces of the corresponding two bolts.

[0017] By adopting the above technical solution: the semicircular design enables the fixing ring and the anti-slip pad to be assembled around the installation part more conveniently during installation, reducing the installation difficulty and time.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] 1. In the present utility model, when it is necessary to adjust the sludge scraping angle, the angle of the mounting block within the fixed head can be rotated, thereby driving the rotation of the adjusting plate connected thereto. Since the slider is movably sleeved on the adjusting plate, and the fixing block on the slider is connected to the connecting assembly through the screw rod, when the adjusting plate rotates, it will drive the slider to move on the adjusting plate, thereby changing the angle of the blade body. At the same time, the blade body directly contacts the surface where sludge needs to be scraped for sludge scraping operation. Then, by rotating the screw rod with the knob, the screw rod is threadedly connected into the second screw hole at a suitable position and extends into the third screw hole, thereby fixing the position of the slider, and further fixing the use angle of the blade body;

[0020] 2. In the present utility model, the entire blade structure is fixedly installed at the required position through the right fixing assembly and the left fixing assembly. The fixing ring, anti-slip pad, and anti-slip strip in the left fixing assembly play a role in stable connection and increasing friction, and the fixing effect is further enhanced through bolts and nuts.

[0029] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0030] A sludge scraping blade structure with adjustable sludge scraping angle, comprising a mounting plate 1. The left end of the mounting plate 1 is fixedly connected with a right fixing component 2. The rear part of the outer surface of the right fixing component 2 is movably installed with a left fixing component 3 through a hinge. The right fixing component 2 and the left fixing component 3 have the same structure and are distributed symmetrically left and right. Both the upper part and the lower part of the left end of the left fixing component 3 are threadedly connected with two bolts 4. The right parts of the outer surfaces of the two bolts 4 are both threadedly connected with nuts 5. The upper part of the right end of the mounting plate 1 is fixedly connected with a connecting component 6, and the lower part of the right end of the mounting plate 1 is fixedly connected with an adjusting component 7.

[0031] In this embodiment, the adjusting assembly 7 includes a fixed head 71. An installation block 72 is movably installed on the front inner wall surface and the rear inner wall surface of the fixed head 71 through bearings. A regulating plate 73 is fixedly connected to the right end of the installation block 72. A slider 74 is movably sleeved on the regulating plate 73. A fixed block 75 is fixedly connected to the upper end of the slider 74. A third screw hole 76 is opened at the upper end of the fixed block 75. A blade body 77 is fixedly connected to the lower end of the regulating plate 73. The left end of the fixed head 71 is fixedly connected to the right end of the mounting plate 1. There is a gap between the outer surface of the installation block 72 and the inner wall surface of the fixed head 71. The connecting assembly 6 includes a connecting plate 61 and a screw 62. A plurality of second screw holes 63 penetrating up and down are opened at the upper end of the connecting plate 61. A knob 64 is fixedly connected to the upper end of the screw 62. A plurality of anti-slip grooves 65 are opened on the outer surface of the knob 64. The left end of the connecting plate 61 is fixedly connected to the right end of the mounting plate 1. The outer surface of the screw 62 is threadedly connected to the inner wall surfaces of the corresponding second screw holes 63 and the third screw hole 76.

[0032] Through the above solution: When it is necessary to adjust the sludge scraping angle, by rotating the installation block 72 in the fixed head 71, since the installation block 72 is fixedly connected to the regulating plate 73, the regulating plate 73 is driven to rotate. The slider 74 on the regulating plate 73 can move relative to it. When the regulating plate 73 rotates, the slider 74 will move on the regulating plate 73. The third screw hole 76 on the fixed block 75 is threadedly connected to the screw 62, and the screw 62 is also threadedly connected to the second screw hole 63 on the connecting plate 61 in the connecting assembly 6. By rotating the knob 64 to drive the screw 62 to rotate, due to the threaded fit of the screw 62 with the second screw hole 63 and the third screw hole 76, the position of the slider 74 can be fixed or adjusted.

[0033] In this embodiment, the left fixing assembly 3 includes a fixing ring 31. An anti-slip pad 32 is fixedly connected to the inner wall surface of the fixing ring 31. A plurality of anti-slip strips 33 are fixedly connected to the inner wall surface of the anti-slip pad 32. A fixing plate 34 is fixedly connected to the front part of the outer surface of the fixing ring 31. First screw holes 35 penetrating left and right are opened at the upper left part and the lower left part of the fixing plate 34. The outer surface of the fixing ring 31 is movably connected to the outer surface of the right fixing assembly 2 through a hinge. Both the fixing ring 31 and the anti-slip pad 32 are arranged in a semi-circular shape. The inner wall surfaces of the two first screw holes 35 are respectively threadedly connected to the outer surfaces of the corresponding two bolts 4.

[0034] Through the above solution: During installation, after connecting the left fixing assembly 3 and the right fixing assembly 2 through a hinge, they are closed around the installation part, so that the fixing ring 31 and the anti-slip pad 32 and the anti-slip strips 33 inside it are in contact with the installation part. Then, the bolts 4 are passed through the first screw holes 35 on the fixing plate 34 and tightened in cooperation with the nuts 5, so as to further enhance the fixing effect and ensure that the entire sludge scraping blade structure can be firmly installed at the specified position.

[0035] It should be noted that the present utility model is a blade structure of a sludge scraper with adjustable sludge scraping angle. During use, first, the entire blade structure is fixedly installed at the required position through the right fixing component 2 and the left fixing component 3. The fixing ring 31, anti-slip pad 32 and anti-slip strip 33 in the left fixing component 3 play a role in stable connection and increasing friction, and the fixing effect is further strengthened through the bolt 4 and the nut 5. When the sludge scraping angle needs to be adjusted, the angle of the mounting block 72 in the fixed head 71 can be rotated, thereby driving the connected adjusting plate 73 to rotate. Since the slider 74 is movably sleeved on the adjusting plate 73, and the fixing block 75 on the slider 74 is connected to the connecting component 6 through the screw rod 62, when the adjusting plate 73 rotates, it will drive the slider 74 to move on the adjusting plate 73, thereby changing the angle of the blade body 77. At the same time, the blade body 77 directly contacts the surface where sludge needs to be scraped for sludge scraping operation. Then, the screw rod 62 is rotated through the knob 64, and the screw rod 62 is threadedly connected into the second screw hole 63 at an appropriate position and extends into the third screw hole 76, so as to fix the position of the slider 74, and further fix the use angle of the blade body 77.
