Description

Technical Field

[0001] The invention relates to the technical field of stone cutting, in particular to a concrete mixing station with dust-free loading. Background Art

[0002] Concrete is an artificial stone made by mixing cementitious materials, water, coarse and fine aggregates, admixtures and other raw materials in appropriate proportions and hardening them after a certain period of time. The concrete mixing station is a combined device used for centralized mixing of concrete, also known as a concrete prefabrication site. Due to its high degree of mechanization and automation, its productivity is also high, and it can ensure the quality of concrete and save cement. It is often used in large and medium-sized water conservancy, power, bridge and other projects with large concrete projects, long construction periods and concentrated construction sites. Since stone is needed as aggregate in concrete, large pieces of stone need to be cut when mixing concrete.

[0003] Publication No. CN118269232B discloses a building stone processing device. The first striking assembly and the second striking assembly on the operating arm cooperate to compress the stone. The first striking assembly and the second striking assembly are both connected to a rotary drive assembly. Only one rotation is required to achieve the striking action of the first striking assembly. The second striking assembly quickly achieves a second striking action under the action of rotational inertia. The first striking assembly achieves the first hammering of the stone by the first striking assembly, and the second hammering of the stone by the second striking assembly. The two hammerings are performed continuously and quickly, thereby achieving rapid stone segmentation and effectively reducing the generation of stone chips. However, this patent still has the following problems in actual use:

[0004] Although the building stone processing device realizes the second hammering of the stone by the second struck component through the second striking component, and the two hammerings are carried out continuously and quickly, thereby realizing rapid division of the stone and effectively reducing the generation of stone chips, the hammering of the stone will cause stone chips to splash, thereby causing dust pollution. At the same time, the hammering of the stone cannot control the degree of stone crushing, affecting the subsequent mixing with concrete raw materials, thereby affecting the quality of the concrete.

[0005] Therefore, a concrete mixing plant with dust-free loading is proposed to solve the above problems. Summary of the Invention

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the concrete mixing station with dust-free loading utilizes a dust collector and a dust suction fan to absorb dust generated by cutting stones, and at the same time, the connecting pipes on both sides of the dust collecting hood can absorb dust generated at the feed pipe. The crushing motor drives the meshing gear set and the crushing roller to rotate, thereby driving the crushing cutter head to rotate relative to each other, and can crush the cut stones. The specific contents are as follows:

[0022] 1. By setting up a cutting dust-proof mechanism, not only can the dust generated by cutting stones be absorbed by the dust collector and the dust-absorbing fan, but also the dust generated at the feed pipe can be absorbed through the connecting pipes on both sides of the dust hood. The guide plate can be used to make the small pieces of stone produced by cutting fall onto the top side of the dust-proof rotating plate, so that the dust-proof rotating plate rotates, so that the stone falls into the crushing box for crushing. Under the action of the gravity of the counterweight ring and the counterweight block, the dust-proof rotating plate can be rotated to a horizontal position, thereby sealing the feed pipe and avoiding a large amount of stone produced when crushing the stone. Dust is collected and overflows from the dust-proof rotating plate, causing dust pollution. A small amount of overflowed dust can be absorbed by the connecting pipe. The double dust-proof structure can absorb the dust, thereby improving the dust absorption effect. The threaded connection between the threaded block and the counterweight block can be used to replace the counterweight blocks of different weights, thereby controlling the amount of stone falling at one time. The first sprocket transmission assembly and the translation threaded rod are driven by the translation motor to rotate, so that the translation thread sleeve drives the electric lifting rod and the cutting fixed plate to move horizontally, so that the stone can be cut by the cutting saw blade The horizontal cutting is performed by rotating the motor to drive the rotating worm. The meshing connection between the rotating worm and the rotating worm wheel can realize the rotation of the rotating worm wheel and the adjusting rotating disk. The sliding connection between the limit fixing block and the reciprocating rotating bracket can drive the rotating gear to rotate. The meshing connection between the rotating gear and the reciprocating rack can drive the cutting saw blade to reciprocate, thereby realizing the cutting of the stone. The adjusting knob drives the adjusting threaded rod to rotate, so that the adjusting threaded sleeve drives the limit fixing block to move, and the rotation radius of the limit fixing block can be adjusted, thereby adjusting the reciprocating distance of the cutting saw blade. The reciprocating distance can be adjusted according to the hardness of the stone, which is convenient for cutting stones of different hardness. The feature of the rotation connection between the rotating piece and the reciprocating rack allows the horizontally placed cutting saw blade to be rotated to a vertical direction, and cooperates with the electric lifting rod to perform vertical cutting of the stone, which is convenient for cutting the stone into small pieces and facilitating the subsequent crushing of the stone. The cutting saw blade can be replaced by the fixing bolt to avoid the phenomenon of the cutting saw blade being damaged after attempting to cut the stone, thereby affecting the effect of subsequent stone cutting.

[0023] 2. By setting up the crushing and mixing mechanism, not only can the crushing motor drive the meshing gear set and the crushing roller to rotate, thereby driving the crushing cutter head to rotate relatively, the cut stone can be crushed, and the protective spring can prevent the crushing cutter head from being damaged due to the high hardness of the stone when crushing the stone. The cleaning motor drives the third sprocket transmission assembly and the cleaning threaded rod to rotate, so that the cleaning thread sleeve drives the cleaning brush to move, thereby cleaning the crushed stone on the surface of the filter screen. The first conveying motor drives the first conveying spiral blade to rotate, and the stone that has not reached the crushing effect will be removed under the action of the stone The crushed stones are transported to the top of the crushing roller for repeated crushing. The second sprocket transmission assembly and the vibration rotating rod are driven to rotate by the vibration motor. Under the action of the vibration cam, the vibration guide plate vibrates to facilitate the guidance of uncrushed stones between the crushing rollers for repeated crushing. The second conveying motor drives the second spiral conveying blade to rotate and transport the crushed stones to the mixing box. The mixing motor is started to drive the mixing rotating rod to rotate, so as to mix the stones and concrete raw materials. The mixing tripod is used to drive the mixing spiral scraper to rotate, which can clean the inner wall of the mixing box to avoid the phenomenon of raw material residue.

The characteristics of the meshing connection between the rotating worm 125 and the rotating worm wheel 126 can realize the rotation of the rotating worm wheel 126 and the adjusting rotating disk 127, and the characteristics of the sliding connection between the limiting fixed block 131 and the reciprocating rotating bracket 132 can be used to drive the rotating gear 133 to rotate, and the characteristics of the meshing connection between the rotating gear 133 and the reciprocating rack 134 can drive the cutting saw blade 138 to reciprocate, thereby To achieve stone cutting, the adjusting knob 128 drives the adjusting threaded rod 129 to rotate, so that the adjusting threaded sleeve 130 drives the limiting fixed block 131 to move, and the rotation radius of the limiting fixed block 131 can be adjusted, thereby adjusting the reciprocating distance of the cutting saw blade 138. The reciprocating distance can be adjusted according to the hardness of the stone, which is convenient for cutting stones of different hardness. The horizontally placed cutting saw blade 138 can be rotated to a vertical direction through the rotation connection between the rotating piece 137 and the reciprocating rack 134, and the electric lifting rod 121 can be used to perform vertical cutting of the stone, which is convenient for cutting the stone into small pieces and facilitating the subsequent crushing of the stone. The cutting saw blade 138 can be replaced through the fixing bolt 139 to avoid damage to the cutting saw blade 138 after attempting to cut the stone, thereby affecting the effect of subsequent stone cutting.

[0043] Secondly, the dust generated by cutting the stone is absorbed by the dust collector 104 and the dust suction fan 105. At the same time, the dust generated by the feed pipe 107 can be absorbed by the connecting pipes 106 on both sides of the dust collecting cover 103. The guide plate 108 can make the small pieces of stone produced by cutting fall to the top side of the dustproof rotating plate 110, and the dustproof rotating plate 110 is rotated to make the stone fall into the crushing box 201 for crushing. Under the action of the gravity of the counterweight ring 111 and the counterweight block 114, the dustproof rotating plate 110 can be rotated. The plate 110 rotates to the horizontal position, thereby closing the feed pipe 107 to prevent a large amount of dust from being generated when crushing the stone, and from overflowing from the dust-proof rotating plate 110, thereby causing dust pollution. A small amount of overflowed dust can be absorbed by the connecting pipe 106. By setting up a double dust-proof structure, the dust can be absorbed, thereby improving the dust absorption effect. By installing the threaded block 113 and the counterweight block 114 in threaded connection, the counterweight blocks 114 of different weights can be replaced to control the amount of stone falling at one time.

[0044] Finally, the crushing motor 202 is used to drive the meshing gear set 203 and the crushing roller 204 to rotate, thereby driving the crushing cutter head 206 to rotate relative to each other, so as to crush the cut stones. The protective spring 205 can prevent the crushing cutter head 206 from being damaged due to the high hardness of the stones when crushing the stones. The cleaning motor 214 drives the third sprocket transmission assembly 211 and the cleaning threaded rod 212 to rotate, so that the cleaning threaded sleeve 213 drives the cleaning brush 215 to move, thereby cleaning the crushed stones on the surface of the filter screen 231. The first conveying motor 217 drives the first conveying spiral blade 218 to rotate, and the stones that have not reached the crushing effect are removed from the filter screen 231. The stone is transported to the top of the crushing roller 204 for repeated crushing. The vibration motor 210 drives the second sprocket transmission assembly 207 and the vibration rotating rod 208 to rotate. Under the action of the vibration cam 209, the vibration guide plate 230 vibrates to facilitate the introduction of uncrushed stone into the space between the crushing rollers 204 for repeated crushing. The second conveying motor 221 drives the second spiral conveying blade 222 to rotate, and the crushed stone is transported to the mixing box 224. The mixing motor 225 is started to drive the mixing rotating rod 226 to rotate, so as to mix the stone and concrete raw materials. The mixing tripod 227 is used to drive the mixing spiral scraper 228 to rotate, which can clean the inner wall of the mixing box 224 to avoid the phenomenon of raw material residue.
