Description

Technical Field

[0001] The invention relates to the technical field of stone cutting, in particular to a concrete mixing station with dust-free feeding. 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. A concrete mixing station is a combined device used to centrally mix 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 engineering volume, long construction period and concentrated construction sites. Since stone is needed as aggregate in concrete, large pieces of stone need to be cut when mixing concrete.

[0003] Announcement No. CN118269232B discloses a building stone processing device, which compresses the stone by the cooperation of the first striking component and the second striking component on the operating arm, and connects the first striking component and the second striking component to the rotating drive component. Only one rotation action is required to realize the striking action of the first striking component, and the second striking component quickly realizes the second striking action under the action of the rotation inertia. The first striking component realizes the first hammering of the stone by the first striking component, and the second hammering of the stone by the second striking component is realized by the second striking component. The two hammerings are carried out continuously and quickly, thereby realizing the rapid segmentation of the stone and effectively reducing the generation of stone chips. However, the 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 segmentation 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, which affects the subsequent mixing with concrete raw materials, thereby affecting the quality of the concrete.

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

[0006] The object of the present invention is to provide a concrete mixing station with dust-free loading, so as to solve the problem that although the building stone processing device proposed in the above background technology realizes the second hammering of the stone by the second struck component through the second striking component, the two hammerings are carried out continuously and quickly, thereby realizing the rapid division of the stone and effectively reducing the generation of stone chips, but when the stone is hammered, stone chips will be splashed, thereby causing dust pollution, and at the same time, the hammering of the stone cannot control the degree of stone crushing, which affects the subsequent mixing with concrete raw materials, thereby affecting the quality of concrete.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the concrete mixing station with dust-free feeding 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 cover can absorb dust generated at the feeding pipe, and the crushing motor drives the meshing gear set and the crushing roller to rotate, thereby driving the crushing cutter head to rotate relatively, and the cut stones can be crushed. The specific contents are as follows:

[0022] 1. By setting up the cutting dust prevention mechanism, not only can the dust generated by cutting stones be absorbed by the dust collector and the dust suction fan, but also the dust generated by the feed pipe can be absorbed by the connecting pipes on both sides of the dust collecting cover. The guide plate can make the small pieces of stone produced by cutting fall to the top side of the dustproof rotating plate, so that the dustproof rotating plate rotates, so that the stone falls into the crushing box for crushing. Under the gravity of the counterweight ring and the counterweight block, the dustproof rotating plate can be rotated to a horizontal level, thereby sealing the feed pipe and avoiding a large amount of stone produced when crushing stones. Dust is collected and overflows from the dust-proof rotating plate, thus 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. By installing the threaded block and the counterweight block with threaded connection, the counterweight blocks of different weights can be replaced to control the amount of stone falling at one time. The first sprocket transmission assembly and the translation threaded rod are driven to rotate by the translation motor, 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 driving the rotating worm to rotate by the rotating motor. The characteristics of the meshing connection between the rotating worm and the rotating worm wheel can be used to realize the rotation of the rotating worm wheel and the adjusting rotating disk. The characteristics of the sliding connection between the limit fixing block and the reciprocating rotating bracket can be used to drive the rotating gear to rotate. The characteristics of the meshing connection between the rotating gear and the reciprocating rack can be used to drive the cutting saw blade to reciprocate, thereby realizing the cutting of the stone. The adjusting threaded rod is driven to rotate by the adjusting knob, 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 characteristics of the rotation connection between the rotating piece and the reciprocating rack can be used to rotate the horizontally placed cutting saw blade to the vertical direction, and cooperate 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 damaging the cutting saw blade after trying 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 be used to drive the meshing gear set and the crushing roller to rotate, thereby driving the crushing cutter head to rotate relatively, and the cut stone can be crushed. 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 threaded 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 by the action of the stone that has not reached the crushing effect. 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 by the vibration motor to rotate. Under the action of the vibration cam, the vibration guide plate vibrates to facilitate the introduction of unbroken 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, so as to 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 be used to realize the rotation of the rotating worm wheel 126 and the adjusting rotating disk 127. The characteristics of the sliding connection between the limit fixing block 131 and the reciprocating rotating bracket 132 can drive the rotating gear 133 to rotate. 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 hardnesses. Through the characteristic of the rotating plate 137 and the reciprocating rack 134 being rotatably connected, the horizontally placed cutting saw blade 138 can be rotated to a vertical direction, and cooperated with the electric lifting rod 121 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 by the fixing bolt 139 to avoid the phenomenon that the cutting saw blade 138 is damaged after trying 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, so that the dustproof rotating plate 110 is rotated, so that the stone falls into the crushing box 201 for crushing. Under 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 a horizontal position, thereby closing the feed pipe 107 to prevent a large amount of dust from being generated when crushing stones, 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 threaded connection with the counterweight block 114, 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 relatively, so that the cut stone can be crushed. The protective spring 205 can prevent the crushing cutter head 206 from being damaged due to the high hardness of the stone when crushing the stone. 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, so as to clean the crushed stone on the surface of the filter screen 231. The first conveying motor 217 drives the first conveying spiral blade 218 to rotate, and the stone that has not reached the crushing effect is removed by the action of the stone that has not reached the crushing effect. 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 unbroken stone into 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 drives the mixing spiral scraper 228 to rotate, so as to clean the inner wall of the mixing box 224 to avoid the phenomenon of raw material residue.
