Description

Technical Field

[0001] The utility model relates to the technical field of sand making machine equipment, and more specifically, to a dust-proof double-roller sand making machine. Background Art

[0002] Sand making machine is widely used in the production of metal and non-metallic ores, cement, refractory materials, abrasives, glass raw materials, building aggregates, artificial sand, river pebbles, mountain rocks (limestone, granite, basalt, diabase, andesite, etc.), ore tailings, stone chips, building aggregates, road surface materials, cushion materials, asphalt concrete and cement concrete aggregates, and various metallurgical slags. It is superior to other types of crushers in the production of medium-hard, extra-hard and abrasive materials such as silicon carbide, corundum, sintered bauxite, magnesia, etc. It can process various metallurgical slags when used with hydraulically protected jaw crushers. It is particularly suitable for construction sand and road sand and gravel.

[0003] However, during the use of the current sand making machine, after the material falls into the feed port, the crushing roller in the crushing chamber crushes the material to make sand, and the crushed material falls onto the conveyor belt, and the conveyor belt and support bars are used to screen the sand and gravel. However, a large amount of dust will be generated in this process, and the dust can easily pass through the crushing chamber and drift to the outside, resulting in a relatively poor overall processing environment, affecting the health of the workers. For this reason, this scheme proposes an anti-dust double-roller sand making machine. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. Example

[0029] See also Figure 1-4 A dust-proof double-roller sand making machine comprises a base frame 1, a base 2 is fixedly connected to the upper end of the base frame 1, a motor 3 is installed on the upper end of the base frame 1, the motor 3 is located on the left side of the base 2, a reducer assembly 4 is fixedly connected to the output end of the motor 3, a hopper assembly 5 is installed on the upper end of the base 2, a bracket 1 6 is fixedly connected to the outer end of the hopper assembly 5, a bracket 2 7 is fixedly connected between the bracket 1 6 and the base frame 1, and the side ends of the hopper assembly 5 are respectively penetrated and installed with A main roller assembly 8 and an auxiliary roller assembly 9, wherein the outer ends of the main roller assembly 8 and the auxiliary roller assembly 9 are sleeved with belts, and one end of the main roller assembly 8 is fixedly connected to the output shaft of the reducer assembly 4, an adjusting spring 10 is installed between the bracket 7 and the hopper assembly 5, a feed port 11 is provided at the upper end of the hopper assembly 5, a crushing chamber 12 is provided inside the hopper assembly 5, the crushing chamber 12 is located on the left side of the feed port 11, and a dust suppression component 14 is installed inside the crushing chamber 12.

[0030] During the use of this scheme, the main components of the main machine are composed of two parts, one is the main roller assembly, and the other is the auxiliary roller assembly. During operation, the motor 3 outputs power to drive the reducer 4 to rotate. The flange of the reducer 4 is directly connected to the motor flange and the main machine flange with bolts using a vibration reduction isolation device, driving the main roller assembly 8 to rotate. Because the main roller skin is in direct contact with the auxiliary roller skin surface, a large friction force is generated to drive the auxiliary roller assembly 9 to work, thereby generating a relative extrusion force on the roller skin contact surface. When squeezing stones, the stones are crushed by squeezing, bending, and shearing, and the stones are squeezed and rubbed between the two roller skins to form a relatively rounded shape.

[0031] Among them, in this embodiment, in order to prevent the crushing rollers in the crushing chamber 12 from generating a large amount of dust when crushing materials and making sand during operation, resulting in a relatively bad overall processing environment, affecting the health of workers and polluting the environment, this solution installs a dust suppression component 14 above the crushing chamber 12, so that during the overall operation, the dust suppression component 14 can absorb a large amount of dust generated by crushing materials and making sand, perform dust suppression treatment, and avoid dust from flying wantonly, thereby ensuring the health of personnel and improving the working environment;

[0032] At the same time, in this embodiment, in order to enable the dust suppression component 14 to effectively perform dust suppression work for a long time, the present solution can also open the dust suppression component 14 by rotating it, and take out the internal dust collecting parts, and rinse them with clean water, so as to facilitate subsequent multiple uses.

[0033] See also Figure 1-3 The dust suppression assembly 14 includes a cover 141 rotatably connected between the inner walls of the crushing chamber 12, a connecting frame 142 is fixedly connected to the lower end of the cover 141, a dust inlet hole 143 is provided at the lower end of the connecting frame 142, a storage groove 144 is provided at the side end of the connecting frame 142, and a dust collecting part 145 is provided inside the storage groove 144.

[0034] Furthermore, the upper end of the cover 141 is fixedly connected to a limit bar 146 .

[0035] During use of the present solution, the dust collecting member 145 is inserted into the storage groove 144 at the side end for storage until the dust collecting member 145 is flush with the cover 141, and then the cover 141 is rotated to cause the connection frame 142 and the dust collecting member 145 to be located as a whole inside the crushing chamber 12 for dust suppression. When the crushing roller in the crushing chamber 12 generates a large amount of dust by crushing the material to make sand, the dust enters the dust collecting member 145 through the dust inlet hole 143 at the bottom of the connection frame 142, and the dust collecting member 145 absorbs the dust to avoid the phenomenon of a large amount of dust flying arbitrarily.

[0036] At the same time, when the cover 141 rotates, the cover 141 can always rotate to the same level as the crushing chamber 12 due to the limitation of the limiting bar 146, and is not easy to fall into the crushing chamber 12 and make it difficult to take it out later.

[0037] See also Figure 3-4 The dust collecting part 145 includes a dust box 1451 provided between the inner walls of the storage tank 144, filter screens 1452 are embedded at the upper and lower ends of the dust box 1451, and a built-in groove 1453 is opened at the side end of the dust box 1451. A plurality of uniformly distributed plastic strips 1454 are fixedly connected between the upper and lower inner walls of the filter screen 1452, and a plurality of plastic strips 2 1455 are fixedly connected to the side ends of the plastic strips 1454. A plurality of traction ropes 1456 are fixedly connected to the inner top end of the filter screen 1452, and a rubber ball 1457 is fixedly connected to the lower end of the traction rope 1456. A dust suction pad 1458 is embedded on the inner side wall of the dust box 1451.

[0038] Furthermore, a plush fabric cover is provided on the side end of the middle portion of the rubber ball 1457 .

[0039] During the use of the present invention, the rubber ball 1457 inside the dust box 1451 swings left and right under the suspension of the traction rope 1456 due to the vibration during the overall operation, and the rubber ball 1457 continuously contacts and rubs with the plastic strip 1 1454 during the swinging process, and the plastic strips 2 1455 at multiple side ends simultaneously increase the contact area with the rubber ball 1457 and with each other, and the plastic strips 1 1454, the plastic strips 2 1455 and the rubber ball 1457 are in contact with each other. 7, under the large amount of contact and friction between each other, the components inside the dust box 1451 are all attached with a layer of static electricity, and under the electrostatic dust absorption effect of the magnetic field, the dust that is randomly raised in the air is absorbed to the surface, reducing the amount of dust raised, and the plush fabric cover set on the side end of the middle part of the rubber ball 1457 and the dust pad 1458 placed on the side wall of the dust box 1451 simultaneously absorb the dust, further reducing the phenomenon of random dust dispersion and improving the surrounding working environment;

[0040] Later, personnel can also pull the built-in groove 1453 to take it out from the storage tank 144, so that the dust attached to its internal components can be flushed away by flushing cleaning, which is beneficial for subsequent dust suppression work.

[0041] See also Figure 1-2 A material blocking plate 13 is rotatably connected between the inner walls of the feed port 11 , and an electric push rod is installed between the bottom of the material blocking plate 13 and the inner wall of the feed port 11 .

[0042] During use of the present invention, the electric push rod can be used to change the inclination angle of the material blocking plate 13, thereby controlling the opening size of the feed port 11 to achieve uniform material feeding.

[0043] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
