Description

Technical Field

[0001] This utility model relates to the field of power pole production technology, specifically to a raw material mixing device for cement power pole production. Background Technology

[0002] Cement utility poles are typically cylindrical or conical in shape, with an internal longitudinal and transverse steel reinforcement framework to enhance their tensile, compressive, and bending strength. The exterior is constructed of poured cement concrete, forming a robust protective layer.

[0003] Publication No. CN220840888U discloses a raw material mixing device for electric pole production. It uses a vacuum cleaner with a suction pipe to remove dust generated by the raw materials poured into the inlet, and then discharges the dust into a mixing tank through an exhaust pipe. The structure is simple and practical, effectively solving the problem of inconveniently removing dust generated by the poured-in raw materials. However, this patent still has the following problems in actual use:

[0004] When mixing cement, the cement raw materials are directly put into the mixing device, which makes it inconvenient to screen the cement. This is because the cement may contain some lumps. If it is not screened in advance, the lumps will directly enter the device and participate in the mixing, which will not only affect the quality of the mixing, but also require more mixing time to fully mix the lumps.

[0005] A raw material mixing device for cement pole production is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a raw material mixing device for cement pole production, so as to solve the problem mentioned in the background art that it is currently inconvenient to screen cement because cement may contain some lumpy cement. If it is not screened in advance, the lumpy cement will directly enter the device body and participate in the mixing, which not only affects the mixing quality, but also requires more mixing time to fully mix the lumpy cement.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a raw material mixing device for cement pole production, comprising a device body and a stirring structure installed inside the device body;

[0008] The device body has a feeding port on the top, a feeding port on one side, and a discharge valve on the bottom.

[0009] Also includes:

[0010] The device body is equipped with a crushing and screening assembly. The crushing and screening assembly includes a connecting shell, which is fixed inside the device body. A screen is slidably connected to the bottom of the connecting shell.

[0011] The connecting shell has a rotating rod symmetrically rotatably connected inside, and the rotating rod has a crushing blade fixed symmetrically at the top and bottom. A gear is fixedly connected to one side of each rotating rod on both sides, and the two gears are meshed together.

[0012] One of the rotating rods passes through the interior of the connecting shell and is located inside the device body, and is rotatably connected to the device body. A motor is installed on one side of the device body, and the output end of the motor is fixedly connected to the rotating rod located inside the device body.

[0013] Preferably, a pressing rod is fixedly connected to the rotating rod that is fixed to the output end of the motor, and a rotating wheel is rotatably connected inside the pressing rod.

[0014] Preferably, the device body has mounting blocks symmetrically fixed inside, and a first spring is fixedly connected to the top of the mounting blocks.

[0015] Preferably, a knocking rod is fixedly connected to the top of the first spring, and a telescopic rod is fixedly connected between the knocking rod and the mounting block.

[0016] Preferably, the striking rod abuts against the screen, and a mounting plate is fixedly connected to the top of the striking rod, with the rotating wheel abutting against the mounting plate.

[0017] Preferably, a disassembly assembly is installed on one side of the device body, and a slide rod is slidably connected to one side of the device body. One side of the slide rod is fixedly connected to a screen, and a pull block is fixedly connected to the other side of the slide rod. The slide groove through which the slide rod slides inside the device body can pass through the screen, and an mounting plate is installed on one side of the device body.

[0018] Preferably, a second spring is fixedly connected to the bottom of the mounting plate, and a fixing plate is fixedly connected to the bottom of the second spring. A limit strip is fixedly connected to the top of the fixing plate, and the limit strip slides inside the mounting plate. A retaining strip is fixedly connected to the bottom of the fixing plate, and the retaining strip engages with the pull block.

[0019] Compared with the prior art, the beneficial effects of this utility model are: this raw material mixing device for cement pole production can conveniently screen the cement before mixing, thereby avoiding the presence of cement lumps in the cement, which would affect the mixing process. The specific details are as follows:

[0020] 1. Start the motor, causing one of the rotating rods to rotate. This, combined with the gears on both sides, causes both rotating rods to rotate simultaneously. The rotation of the rotating rods drives the crushing blades, breaking up any lumps of cement. The crushed cement is then screened through a sieve. Simultaneously, the rotating rods drive the extrusion rods, which in turn drive the rotating wheel in a circular motion. As the wheel moves, it presses against the mounting plate, causing the hammer rod to move downwards and compress the first spring. This spring then drives the hammer rod to strike the sieve, aiding in screening and preventing accumulation. When the rotating wheel reaches a certain point, it presses against the mounting plate again, causing the hammer rod to continuously strike the sieve. The crushed and screened lime falls back to the bottom of the device. Other materials to be mixed are then added through the feed inlet and stirred by the mixing structure. Finally, the mixed lime is discharged through a valve. This process allows for the crushing and screening of lime before mixing, preventing lumps from affecting the mixing speed.

[0021] 2. When the screen needs to be disassembled and replaced, pull the fixing plate upwards. The fixing plate will compress the second spring and drive the locking strip to disengage from the inside of the pull block, thereby releasing the limit on the pull block. Then pull the pull block to the left. The pull block will drive the sliding rod to move, thereby pulling the screen out from the inside of the connecting shell. The screen will then be pulled out from one side of the device body. Then insert the new screen 402. Finally, release the fixing plate 505 to replace the screen 402. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-6 The present invention provides the following technical solution:

[0031] A raw material mixing device for cement pole production includes a device body 1 and a mixing structure 2 installed inside the device body 1. A feeding port 101 is installed at the top of the device body 1, a feed inlet 102 is installed on one side of the device body 1, and a discharge valve 103 is installed at the bottom of the device body 1. A crushing and screening assembly 4 is installed inside the device body 1. The crushing and screening assembly 4 includes a connecting shell 401, which is fixed inside the device body 1, and a screen 402 is slidably connected to the bottom of the connecting shell 401. A rotating rod 403 is symmetrically rotatably connected inside the connecting shell 401, and crushing blades 404 are symmetrically fixed above and below the rotating rod 403. Gears 405 are fixedly connected to one side of each rotating rod 403 on both sides, and the two gears 405 mesh with each other. One rotating rod 403 passes through the interior of the connecting shell 401 and is located inside the device body 1, and is rotatably connected to the device body 1. A motor 4051 is installed on one side of the device body 1. Figure 2-4 As shown, the cement to be mixed is fed into the feed port 101 and then enters the interior of the connecting shell 401. At this time, the motor 4051 is started, causing one of the rotating rods 403 to rotate. In conjunction with the gears 405 on both sides, the rotating rods 403 on both sides will rotate simultaneously. The rotation of the rotating rods 403 will drive the crushing blade 404 to rotate, so that the cement lumps in the cement can be crushed. Finally, the crushed cement is screened through the screen 402. The output end of the motor 4051 is fixedly connected to the rotating rod 403 located inside the device body 1.

[0032] A pressing rod 406 is fixedly connected to a rotating rod 403 fixed to the output end of motor 4051, and a rotating wheel 4061 is rotatably connected inside the pressing rod 406. A mounting block 407 is symmetrically fixed inside the device body 1, and a first spring 408 is fixedly connected to the top of the mounting block 407. A knocking rod 409 is fixedly connected to the top of the first spring 408, and a telescopic rod 410 is fixedly connected between the knocking rod 409 and the mounting block 407. The knocking rod 409 abuts against the screen 402. Figure 3-5 As shown, the rotation of the rotating rod 403 drives the pressing rod 406 to rotate, which in turn drives the rotating wheel 4061 to move in a circular motion. During this motion, the rotating wheel 4061 presses against the mounting plate 411, causing it to move downwards. This movement in turn causes the striking rod 409 to move downwards and compress the first spring 408. When the rotating wheel 4061 reaches a certain point, it disengages from the mounting plate 411, at which point the first spring 408 resets. The first spring 408 then drives the striking rod 409 to strike the screen 402, assisting in screening and preventing accumulation. When the rotating wheel 4061 reaches a certain point, it presses against the mounting plate 411 again, causing the striking rod 409 to continuously strike the screen. After crushing and screening, the lime falls back to the bottom of the device body 1. Then, other materials to be mixed are added through the feed inlet 102, and then the mixing structure 2 is used to stir and mix them. Finally, the mixed lime is discharged through the valve 103 and then collected by other containers. This achieves the crushing and screening of lime before mixing, thus avoiding the presence of lumpy lime affecting the mixing speed. Secondly, considering that this application does not have a dust collection structure, the staff can wear protective clothing or stay away from the device when mixing. The top of the hammer 409 is fixedly connected to the mounting plate 411, and the rotating wheel 4061 abuts against the mounting plate 411.

[0033] A disassembly assembly 5 is installed on one side of the device body 1, and a slide rod 501 is slidably connected to one side of the device body 1. One side of the slide rod 501 is fixedly connected to a screen 402, and a pull block 502 is fixedly connected to the other side of the slide rod 501. A sliding groove through which the slide rod 501 slides inside the device body 1 can pass through the screen 402. An mounting plate 503 is installed on one side of the device body 1. A second spring 504 is fixedly connected to the bottom of the mounting plate 503, and a fixing plate 505 is fixedly connected to the bottom of the second spring 504. A limit strip 506 is fixedly connected to the top of the fixing plate 505. Figure 6As shown, when the screen 402 needs to be disassembled and replaced, the fixing plate 505 can be pulled upwards. The fixing plate 505 will then compress the second spring 504 and simultaneously drive the locking strip 507 to disengage from the inside of the pull block 502, thereby releasing the limit on the pull block 502. Then, the pull block 502 is pulled to the left, and the pull block 502 will drive the slide rod 501 to move, thereby pulling the screen 402 out from the inside of the connecting shell 401. The screen 402 will then be pulled out from one side of the device body 1. Then, the new screen 402 can be inserted. Finally, the fixing plate 505 is released, thereby realizing the replacement of the screen 402. Moreover, the limiting strip 506 slides inside the mounting plate 503, and the bottom of the fixing plate 505 is fixedly connected to the locking strip 507, and the locking strip 507 is engaged with the pull block 502.

[0034] Working principle: Before using this raw material mixing device for cement pole production, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 6 As shown, firstly, the cement to be mixed is fed into the connecting shell 401 through the feeding port 101. At this time, the motor 4051 is started, causing one of the rotating rods 403 to rotate. This, combined with the gears 405 on both sides, causes both rotating rods 403 to rotate simultaneously. The rotation of the rotating rod 403 drives the crushing blade 404 to rotate, thus crushing any lumps of cement. Finally, the crushed cement is screened through the screen 402. Secondly, the rotation of the rotating rod 403 drives the extrusion rod 406 to rotate. The extrusion rod 406 then drives the rotating wheel 4061 to rotate in a circular motion. During this motion, the rotating wheel 4061 presses against the mounting plate 411, causing the mounting plate 411 to move downwards. The mounting plate 411 then drives the knocking rod 409 to move downwards and compress the first spring 408. When the rotating wheel 4061... When the rotor 4061 reaches a certain point, it will detach from the mounting plate 411. At this time, the first spring 408 will reset, and then the first spring 408 will drive the knocking rod 409 to knock on the screen 402, so that the screen 402 can be screened to avoid accumulation. When the rotor 4061 reaches a certain point, it will squeeze the mounting plate 411 again, so that the knocking rod 409 will keep knocking on the screen 402. Finally, the crushed and screened lime falls back to the bottom of the device body 1. Then, other materials to be mixed are added through the feed port 102, and then they are stirred and mixed by the stirring structure 2. Finally, the mixed lime is discharged through the valve 103 and then collected by other containers. This realizes the crushing and screening of lime before mixing, thereby avoiding the presence of lumpy lime that affects the mixing speed.

[0035] When the screen 402 needs to be disassembled and replaced, the fixing plate 505 can be pulled upwards. The fixing plate 505 will then compress the second spring 504 and simultaneously drive the locking strip 507 to disengage from the inside of the pull block 502, thereby releasing the limit on the pull block 502. Then, pull the pull block 502 to the left, and the pull block 502 will drive the slide rod 501 to move, thereby pulling the screen 402 out from the inside of the connecting shell 401. The screen 402 will then be pulled out from one side of the device body 1. Then, insert the new screen 402. Finally, release the fixing plate 505 to replace the screen 402.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
