Description

Technical Field

[0001] The invention relates to the technical field of sand and gravel cleaning in construction engineering, and in particular to a sand and gravel cleaning device used in construction engineering. Background Art

[0002] As a building material, concrete is very important in construction projects. To some extent, the quality of concrete directly affects the final effect of the entire construction project. Concrete is a mixture of sand, powder and water. The ratio of various components is very important, and the quality of each component itself is also very important. For sand and gravel, sand and gravel need to be pre-treated, mainly cleaning to remove the dirt on the surface of sand and gravel.

[0003] Publication number CN114216305A discloses a sand and gravel cleaning device for construction projects, the device includes a frame, a cleaning machine body and a sand and gravel conveyor belt arranged below the discharge port of the cleaning machine body, a water-absorbing belt transmission mechanism and a material-discharging mechanism are arranged above the sand and gravel conveyor belt; the material-discharging mechanism includes a material-discharging plate; the water-absorbing belt transmission mechanism includes a belt, and a water-absorbing layer is arranged on the surface of the belt, and the water-absorbing layer can contact the sand and gravel on the sand and gravel conveyor belt and cooperate with the sand and gravel conveyor belt to make the sand and gravel roll. The device is provided with a water-absorbing belt transmission mechanism and a material-discharging mechanism, and the water-absorbing layer can contact the sand and gravel on the sand and gravel conveyor belt and cooperate with the sand and gravel conveyor belt to make the sand and gravel roll. The sand and gravel fully contact the water-absorbing layer during rolling, thereby transferring the residual water on the surface of the sand and gravel to the water-absorbing layer; the water-squeezing roller can squeeze out the water in the water-absorbing layer, and finally guide it to the cleaning machine through the water-conducting cylinder, so as to realize the recycling and reuse of water, reduce the water consumption of the cleaning machine, and improve the utilization rate of water resources;

[0004] Although the above patent solves the problem of water recycling and reuse, reduces the water consumption of the cleaning machine, and improves the utilization rate of water resources, there are still the following problems. First, after the sand and gravel are cleaned, when they are transported through the conveyor belt, some of the sand and gravel will not be cleaned properly and silt will adhere to the water-absorbing layer. Therefore, when the water-absorbing layer contacts the sand and gravel that have not been cleaned, the silt will adhere to the water-absorbing layer. After the equipment has been running for a long time, the silt on the surface of the water-absorbing layer will increase. After the water-absorbing layer continues to contact with the sand and gravel, it will have a counter-effect phenomenon, and the silt on the water-absorbing layer will be completely cleaned. The sand and gravel will adhere to the conveyor belt, thus affecting the cleaning effect of the sand and gravel. Secondly, the water-absorbing layer and the sand and gravel roll and squeeze, which will cause some of the sand and gravel to adhere to the water-absorbing layer, thus affecting the subsequent operations. Thirdly, when the cleaned sand and gravel are transported by the conveyor belt, water will also adhere to the conveyor belt. After the conveyor belt has been transported for a long time, the accumulated water on the surface of the conveyor belt will affect the sand and gravel, so that after the sand and gravel are wiped dry, they will still adhere to water stains through the conveyor belt. Fourthly, the device cannot crush the sand and gravel after wiping it, and then the sand and gravel are not uniform after the sand and gravel are packaged, thus affecting the subsequent processing operations.

[0016] At least one of the above technical solutions adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0017] Firstly, in the prior art, after the sand and gravel are cleaned, they are transported through the conveyor belt. Since some of the sand and gravel are not cleaned properly, there is a phenomenon of silt adhesion. Therefore, when the water-absorbing layer contacts the sand and gravel that have not been cleaned, the silt will be adhered to the water-absorbing layer. After the equipment has been running for a long time, there will be more and more silt on the surface of the water-absorbing layer. After the subsequent water-absorbing layer continues to contact with the sand and gravel, it will have a counter-effect. The silt on the water-absorbing layer will be adhered to the cleaned sand and gravel, thereby affecting the cleaning effect of the sand and gravel. In addition, the rolling and squeezing of the water-absorbing layer and the sand and gravel will cause some of the sand and gravel to adhere to the water-absorbing layer, thereby affecting subsequent operations. In this device, when the two water-absorbing sponges and the two crushing parts have been working for a long time, the surfaces of the two water-absorbing sponges will absorb a large amount of water and impurities, and the two Small gravel will also adhere to the surface of the crushing parts. At this time, the two water-absorbing sponges and the two crushing parts need to be cleaned to avoid the two water-absorbing sponges from affecting the sand and gravel when absorbing water and the two crushing parts from affecting the crushing effect of the sand and gravel. The adjustment motor is driven to rotate the adjustment gear, thereby driving the first rack and the second rack to move, thereby driving the two crushing devices to move in the direction of the corresponding cleaning chamber, and simultaneously driving the two water-absorbing devices to move into the corresponding cleaning chamber. When the two crushing devices and the two water-absorbing devices are moving toward the corresponding cleaning chamber, the corresponding crushing shafts and water-absorbing shafts in the two crushing devices and the two water-absorbing devices will move in the corresponding cleaning grooves and will not contact the cleaning chamber. When the two water-absorbing sponges collide with When the corresponding cleaning part and the two crushing parts are in contact with the corresponding cleaning brushes, the adjusting motor stops running. At this time, the two water-absorbing sponges will be tightly attached to each other according to the curvature of the corresponding cleaning part to form an arc, thereby increasing the squeezing area of ​​the two water-absorbing sponges when squeezing the two water-absorbing sponges. Therefore, compared with other shapes, several cleaning parts with arc-shaped settings have better squeezing effects. At this time, the two crushing parts and the two water-absorbing sponges are driven by the driving motor to move symmetrically inward. During the symmetrical inward movement of the two water-absorbing sponges, the corresponding cleaning parts can squeeze the two water-absorbing sponges during their rotation, thereby squeezing the water on the two water-absorbing sponges and dropping them to the lower end of the cleaning chamber, through the inclination angle of the lower end of the cleaning chamber. , and discharge the sewage into the cleaning recovery box through the cleaning channel. If the surfaces of the two absorbent sponges are too dirty, the clean water is discharged through the two connecting pipes and falls onto the corresponding absorbent sponges, and then they are cleaned by the corresponding cleaning parts. By setting the tooth-shaped tooth grooves on the cleaning parts, the corresponding cleaning parts can pick out the sand and gravel remaining on the two absorbent sponges and drop them into the cleaning chamber. Similarly, the two cleaning brushes rotate symmetrically inwardly through the two crushing parts, so that the corresponding cleaning brushes can clean the two absorbent sponges during their rotation, thereby cleaning the broken sand and gravel on the two crushing parts and discharging them into the cleaning recovery box through the flow of sewage. After the cleaning of the two absorbent sponges and the two crushing parts is completed,By adjusting the motor operation to move it to the original state, the operation can be repeated.

[0018] Secondly, in the prior art, it is impossible to crush the sand and gravel after wiping them, and further, the sand and gravel are not uniform after being packaged, thus affecting subsequent processing operations. In this device, when the sand and gravel that have been cleaned are discharged through the discharge port, the sand and gravel will just fall to the contact point between the two water-absorbing sponges, and the operation of the driving motor drives the two crushing devices to operate, and the operation of the two crushing devices is driven by the two transmission devices, thereby driving the two water-absorbing devices to operate, the rotation of the second transmission wheel drives the water-absorbing shaft to rotate, the rotation of the water-absorbing shaft drives the first roller on the water-absorbing shaft to rotate, and the rotation of the first roller drives the second roller to rotate through the transmission of the roller belt. The two rollers rotate, thereby driving the water-absorbing sponges to move inward. The extrusion of the roller belt can make the sand and gravel in a relatively uniform state be transported downward to the two crushing devices. During the downward movement, the sand and gravel will come into contact with the two water-absorbing sponges, and the two water-absorbing sponges will absorb the water stains on the surface of the relatively uniform sand and gravel. When the sand and gravel fall to the two crushing devices after passing through the two water-absorbing devices, the two crushing parts roll and squeeze inward, thereby achieving the goal of crushing the sand and gravel into a relatively uniform state. After the sand and gravel are cleaned, they become relatively dry and crushed into a relatively uniform state for packaging and storage, thereby facilitating the subsequent use of the sand and gravel.

[0019] Thirdly, when the crushing size of sand and gravel needs to be adjusted, the adjusting motor is operated to drive the adjusting gear on the output end of the adjusting motor to rotate, and the rotation of the adjusting gear drives the first rack and the second rack to move, thereby driving the two crushing devices to move symmetrically inward or outward, thereby realizing the adjustment of the crushing size of sand and gravel.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings.

[0034] The embodiment of the present invention provides a sand and gravel cleaning device for construction engineering, including a workbench 1, a feed port 11, a connecting pipe 12, a driving device 2, a crushing device 3, a transmission device 4, a water absorbing device 5, an adjusting device 6 and a cleaning device 7, wherein two workbench 1 are provided, and the two workbench 1 are symmetrically arranged on a horizontal plane, the driving device 2 is arranged on the two workbench 1, the crushing device 3 is provided with two, and the two crushing devices 3 are respectively arranged at the upper ends of the two workbench 1, the transmission device 4 is provided with two, the water absorbing device 5 is provided with two, and the two water absorbing devices 5 are respectively provided with a pair of The corresponding transmission device 4 is connected to the corresponding crushing device 3, the adjusting device 6 is connected to the two crushing devices 3, two cleaning devices 7 are provided, and the two cleaning devices 7 are respectively arranged on the two workbenches 1, the discharge port 11 is arranged directly above the two water absorption devices 5, and two connecting pipes 12 are provided, and the two connecting pipes 12 are respectively arranged directly above the two cleaning devices 7. This device can absorb water from the surface of the sand and gravel after the sand and gravel are cleaned, and can also crush them after the water absorption is completed, thereby avoiding excessive moisture and uneven size when being packed in the bag.

[0035] Working principle: When the device is used for sand and gravel, the required packaging bags are first hung on the corresponding hooks 14. When the sand and gravel are cleaned and discharged through the discharge port 11, the sand and gravel will fall exactly to the contact point between the two water-absorbing sponges 56. The operation of the driving motor 21 drives the two crushing devices 3 to operate, and the operation of the two crushing devices 3 is driven by the transmission of the two transmission devices 4, thereby driving the two water-absorbing devices 5 to operate. The rotation of the second transmission wheel 42 drives the water-absorbing shaft 51 to rotate, and the rotation of the water-absorbing shaft 51 drives the first roller 53 on the water-absorbing shaft 51 to rotate. The rotation of the first roller 53 drives the second roller 54 to rotate through the transmission of the roller belt 55, thereby driving the water-absorbing sponge 56 to move inward, and the extrusion of the roller belt 55 can make the sand and gravel in The sand and gravel are transported downward to the two crushing devices 3 in a relatively uniform state, and the sand and gravel will contact the two water-absorbing sponges 56 during the downward movement, and the water stains on the surface of the relatively uniform sand and gravel will be absorbed by the two water-absorbing sponges 56. When the sand and gravel fall to the two crushing devices 3 after passing through the two water-absorbing devices 5, the two crushing members 36 roll and squeeze inward, so as to achieve the crushing of the sand and gravel into a relatively uniform state, so that after the sand and gravel are cleaned, they become relatively dry and crushed into a relatively uniform state for packaging and storage, so as to facilitate the subsequent use of the sand and gravel. When it is necessary to adjust the crushing size of the sand and gravel, the adjusting motor 62 is operated to drive the adjusting gear 63 on the output end of the adjusting motor 62 to rotate, and the adjusting gear 63 rotates to drive the first rack 64 and the second The rack 65 moves, thereby driving the two crushing devices 3 to move symmetrically inward or outward, so as to adjust the crushing size of the sand and gravel. After the two water-absorbing sponges 56 and the two crushing parts 36 have been working for a long time, the surfaces of the two water-absorbing sponges 56 will absorb a large amount of water and impurities, and the surfaces of the two crushing parts 36 will also adhere to the broken small sand and gravel. At this time, the two water-absorbing sponges 56 and the two crushing parts 36 need to be cleaned to avoid the subsequent influence of the two water-absorbing sponges 56 on the sand and gravel when absorbing water and the two crushing parts 36 on the sand and gravel when crushing the sand and gravel. The adjusting motor 62 is driven to rotate the adjusting gear 63, thereby driving the first rack 64 and the second rack 65 to move, thereby driving the two crushing devices 3 to the corresponding cleaning chambers. When the two crushing devices 3 and the two water absorbing devices 5 move in the direction of 72, the two water absorbing devices 5 are also driven to move into the corresponding cleaning chamber 72. When the two crushing devices 3 and the two water absorbing devices 5 move into the corresponding cleaning chamber 72, the corresponding crushing shafts 35 and the water absorbing shafts 51 in the two crushing devices 3 and the two water absorbing devices 5 move in the corresponding cleaning grooves and do not contact the cleaning chamber 72. When the two water absorbing sponges 56 abut against the corresponding cleaning members 73 and the two crushing members 36 abut against the corresponding cleaning brushes 76, the regulating motor 62 stops running. At this time, the two water absorbing sponges 56 are closely attached to the corresponding cleaning members 73 according to the curvature of the cleaning members 73 and also form an arc. Therefore, when the two water absorbing sponges 56 are squeezed, the squeezing area of ​​the two water absorbing sponges 56 is increased.Therefore, the arc-shaped cleaning members 73 have a better squeezing effect than other shapes. At this time, the two crushing members 36 and the two water-absorbing sponges 56 are driven by the driving motor 21 to move symmetrically inward. During the symmetrical inward movement of the two water-absorbing sponges 56, the corresponding cleaning members 73 can squeeze the two water-absorbing sponges 56 during their rotation, so that the water on the two water-absorbing sponges 56 is squeezed out and falls to the lower end of the cleaning chamber 72. Through the inclination angle of the lower end of the cleaning chamber 72, the sewage is discharged into the cleaning recovery box 75 through the cleaning channel 74. If the surfaces of the two water-absorbing sponges 56 are too dirty, the clean water is discharged to the corresponding water-absorbing sponges 56 through the two connecting pipes 12, and then The corresponding cleaning member 73 can clean it, and the tooth-shaped tooth groove on the cleaning member 73 can make the corresponding cleaning member 73 pick out the sand and gravel remaining on the two absorbent sponges 36 and drop it into the cleaning chamber 72. Similarly, the two cleaning brushes 76 rotate symmetrically inward through the two crushing members 36, so that the corresponding cleaning brushes 76 can clean the two absorbent sponges 56 during their rotation, thereby cleaning the broken small sand and gravel on the two crushing members 36 and discharging them into the cleaning recovery box 75 through the flow of sewage.

[0042] Preferably, the two cleaning devices 7 each include a cleaning frame 71, a cleaning chamber 72, a cleaning member 73, a cleaning channel 74 and a cleaning recovery box 75, the cleaning recovery box 75 being arranged on one side of the corresponding workbench 1, the cleaning frame 71 being arranged on the side end of the cleaning recovery box 75, the cleaning chamber 72 being arranged on the cleaning frame 71, the cleaning chamber 72 being arranged on a plurality of cleaning slots, the cleaning member 73 being arranged in two, the two cleaning members 73 being arranged on the inner side wall of the cleaning chamber 72 from top to bottom and corresponding to the corresponding water-absorbing sponge 56, the two cleaning members 73 being arranged with tooth-shaped tooth grooves and the two The tooth-shaped tooth grooves on the cleaning members 73 are staggered, and the two cleaning members 73 are both arc-shaped. The lower end of the cleaning chamber 72 is in an inclined state, and one end of the cleaning channel 74 is connected to the lower end of the cleaning chamber 72 and is connected. The other end of the cleaning channel 74 is located on the cleaning recovery box 75. When the sewage of the sand and gravel on the two absorbent sponges 56 and the two crushing members 36 are discharged into the corresponding cleaning recovery box 75, the sand and gravel and sewage inside the cleaning recovery box 75 can be discharged into the sand and gravel cleaning equipment for reuse through subsequent pipeline coordination, thereby avoiding waste of resources.

[0043] Preferably, it also includes a cleaning brush 76, and two cleaning brushes 76 are provided. The two cleaning brushes 76 are respectively arranged on the inner side walls of the corresponding cleaning chamber 72 and correspond to the corresponding crushing parts 36. After the two water-absorbing sponges 56 and the two crushing parts 36 have been in operation for a long time, the surfaces of the two water-absorbing sponges 56 will absorb a large amount of water and impurities, and the surfaces of the two crushing parts 36 will also adhere to broken small sand and gravel. At this time, the two water-absorbing sponges 56 and the two crushing parts 36 need to be cleaned to avoid the subsequent influence of the two water-absorbing sponges 56 on the sand and gravel when absorbing water and the influence of the two crushing parts 36 on the crushing effect of the sand and gravel when crushing the sand and gravel. The adjusting motor 62 is operated to drive the adjusting gear 63 to rotate, thereby driving the first rack 64 and the second rack 65 to move. The two crushing devices 3 and the two water absorbing devices 5 move toward the corresponding cleaning chambers 72, and simultaneously drive the two water absorbing devices 5 to move into the corresponding cleaning chambers 72. When the two crushing devices 3 and the two water absorbing devices 5 move toward the corresponding cleaning chambers 72, the corresponding crushing shafts 35 and the water absorbing shafts 51 in the two crushing devices 3 and the two water absorbing devices 5 move in the corresponding cleaning grooves and do not contact the cleaning chambers 72. When the two water absorbing sponges 56 abut against the corresponding cleaning members 73 and the two crushing members 36 abut against the corresponding cleaning brushes 76, the regulating motor 62 stops running. At this time, the two water absorbing sponges 56 are tightly attached to the corresponding cleaning members 73 according to the curvature of the cleaning members 73, and also form an arc, thereby squeezing the two water absorbing sponges 56. When the two water-absorbing sponges 56 are symmetrically moved inward, the squeezing area of ​​the two water-absorbing sponges 56 is increased, so the arc-shaped setting of the cleaning members 73 has a better squeezing effect than other shapes. At this time, the two crushing members 36 and the two water-absorbing sponges 56 are driven by the driving motor 21 to move symmetrically inward. During the symmetrical inward movement of the two water-absorbing sponges 56, the corresponding cleaning members 73 can squeeze the two water-absorbing sponges 56 during their rotation, so that the water on the two water-absorbing sponges 56 is squeezed out and falls to the lower end of the cleaning chamber 72. Through the inclination angle of the lower end of the cleaning chamber 72, the sewage is discharged into the cleaning recovery box 75 through the cleaning channel 74. If the surfaces of the two water-absorbing sponges 56 are too dirty, the clean water is discharged into the corresponding The absorbent sponge 56 can be cleaned by the corresponding cleaning member 73. The tooth-shaped tooth groove arrangement on the cleaning member 73 can enable the corresponding cleaning member 73 to pick out the sand and gravel remaining on the two absorbent sponges 36 and drop them into the cleaning chamber 72. Similarly, the two cleaning brushes 76 are symmetrically rotated inwardly through the two crushing members 36, so that the corresponding cleaning brushes 76 can clean the two absorbent sponges 56 during their rotation, thereby cleaning the broken small sand and gravel on the two crushing members 36 and discharging them into the cleaning recovery box 75 through the flow of sewage. After the cleaning of the two absorbent sponges 56 and the two crushing members 36 is completed, the motor 62 is adjusted to move them to their original state and the operation can be repeated.

[0044] Preferably, it also includes hooks 14, and there are a plurality of hooks 14. The hooks 14 are symmetrically arranged on the inner sides of the two workbenches 1 and on the lower sides of the two crushing parts 36. When the sand and gravel are packaged, the required packaging bags are first hung on the corresponding hooks 14, so that the sand and gravel fall into the packaging bags for storage after the operation is completed.
