Description

Technical Field

[0001] The utility model relates to the technical field of cement-stabilized crushed stone layer processing, in particular to a raw material crushing and screening device. Background Art

[0002] Water-stabilizing layer is the abbreviation of cement-stabilized gravel layer, that is, it is completed by using cement to consolidate graded gravel, through compaction, curing and other processes. The graded gravel required in the water-stabilizing layer is often crushed by a crushing device to complete the stone crushing process. Among the operating equipment currently used for stone crushing, roller crushers account for the majority, and their working mechanism is that through the relative rotation between the round rollers, the stones are continuously crushed in the gap between the two round rollers rotating in opposite directions.

[0003] Existing public patent: CN202120117495.1 A water-stabilizing layer base aggregate crushing mechanism, the motor is installed on the crusher casing, the cam is installed on the motor output shaft, the cam cooperates with the corresponding filter screen, and the motor drives the cam to rotate, thereby driving the filter screen to vibrate, so that the gravel will not accumulate and block the filter screen.

[0004] However, the one-size filter in the patent can only be used to screen one-size raw material for the production of water-stabilizing layer. When it is necessary to filter other sizes of raw materials for the production of water-stabilizing layer, the filter needs to be disassembled and taken out. Because the overall size of the equipment is large and the weight is heavy, it is laborious to remove and reinstall the filter. The removal and installation are also time-consuming, which reduces the practicality of the device. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] In view of the deficiencies in the prior art, the utility model provides a raw material crushing and screening device, which has the function of releasing the pull on the fixed block after adjusting the position of the first filter plate, and driving the fixed rod to move into the adjustment slot at the appropriate position under the action of the released elastic force of the fixed spring. The adjustment is convenient and quick, and there is no need to disassemble the first filter plate and the second filter plate. The adjustment is relatively labor-saving, thereby ensuring the flexibility and practicality of the device. It solves the problem that the filter screen of one size in the patent can only be used to screen the water-stable layer production raw materials of one size. When the water-stable layer production raw materials of other sizes need to be filtered, the filter screen needs to be disassembled in and out. Because the overall size of the equipment is large and the weight is heavy, it is more laborious to remove and reinstall the filter screen, and the removal and installation are also more time-consuming, thereby reducing the problem of weak practicality of the device.

[0068] Furthermore, a second connecting groove 18 communicating with the interior of the screening box 3 is provided on the right side surface thereof;

[0069] The inner wall of the screening box 3 is fixedly sleeved with a connecting plate 19, and the right side surface of the connecting plate 19 extends out of the right side surface of the screening box 3 through the second connecting groove 18;

[0076] The crushing roller 6 is located in the crushing box 4 , and the rotating output shaft of the first motor 5 is fixedly connected to any positioning shaft 7 .

[0077] Furthermore, when the first motor 5 is started, the first motor 5 starts to drive the two positioning shafts 7, the two crushing rollers 6, and the two gears 8 to rotate, and then drives the two crushing rollers 6 to engage. At this time, the raw materials for the water-stabilizing layer production can be placed in the crushing box 4, and then the raw materials for the water-stabilizing layer production can be crushed.

[0078] Furthermore, through the accompanying drawings Figure 6 It can be seen that when the first filter plate 12 is displaced left and right, the position of the filter holes on the first filter plate 12 can be adjusted, and then the staggered space between the filter holes of the first filter plate 12 and the second filter plate 13 can be adjusted, and then the particle size of the raw materials that can be filtered by the filter holes can be adjusted synchronously.

[0079] The same principle applies, the vibration motor 9 is started, and the vibration motor 9 drives the screening box 3 to vibrate, and then synchronously drives the first filter plate 12 and the second filter plate 13 to vibrate, and the crushed raw materials fall onto the second filter plate 13 through the crushing box 4, and then are filtered through the staggered filter holes between the second filter plate 13 and the first filter plate 12, and the larger particles are discharged through the inclined first filter plate 12 and the first connecting groove 10, and the smaller particles fall on the connecting plate 19 and are discharged through the second connecting groove 18, so that raw material particles of different sizes can be screened and discharged separately after screening, and the screening efficiency is high, thereby ensuring the efficiency of screening raw materials for water-stabilizing layer production, thereby increasing the practicability of the device.

[0080] Furthermore, by pulling the fixing block 14, the fixing block 14 drives the fixing rod 15 to move upward out of the adjustment slot 17, and simultaneously stretches the fixing spring 16, so that the first filter plate 12 can be pulled left and right at this time, so that the position of the filter holes on the first filter plate 12 can be adjusted, and the staggered space between the filter holes on the upper and lower sides can be adjusted, so that the particle size of the raw materials that can be filtered by the filter holes can be adjusted at will, and the adjustment is convenient, so that the screening box 3 can screen water-stabilizing layer production raw materials of different particle sizes, thereby increasing the applicability of the device and simultaneously increasing the practicality of the device.

[0081] Furthermore, after the position of the first filter plate 12 is adjusted, the pulling of the fixing block 14 is released, and the fixing rod 15 is driven to move into the adjustment slot 17 at a suitable position under the action of the released elastic force of the fixing spring 16. The adjustment is convenient and quick, and there is no need to disassemble the first filter plate 12 and the second filter plate 13. The adjustment is relatively labor-saving, thereby ensuring the flexibility and practicality of the device.

[0082] Furthermore, in this solution, the elastic force of the support spring 2 is sufficient to support the normal operation of the crushing box 4 and the screening box 3.

[0083] Furthermore, when the present solution is used, the base 1 needs to be fixed to prevent the vibration motor 9 from driving the entire device to move during operation, thereby ensuring the stability of the device.

[0084] Working principle: When the device is in use, the position of the filter holes on the first filter plate 12 can be adjusted by displacing the first filter plate 12 left and right, and then the staggered space between the filter holes of the first filter plate 12 and the second filter plate 13 can be adjusted, and then the particle size of the raw materials that can be filtered by the filter holes can be adjusted synchronously.

[0085] The same principle applies, the vibration motor 9 is started, and the vibration motor 9 drives the screening box 3 to vibrate, and then synchronously drives the first filter plate 12 and the second filter plate 13 to vibrate, and the crushed raw materials fall onto the second filter plate 13 through the crushing box 4, and then are filtered through the staggered filter holes between the second filter plate 13 and the first filter plate 12, and the larger particles are discharged through the inclined first filter plate 12 and the first connecting groove 10, and the smaller particles fall on the connecting plate 19 and are discharged through the second connecting groove 18, so that raw material particles of different sizes can be screened and discharged separately after screening, and the screening efficiency is high, thereby ensuring the efficiency of screening raw materials for water-stabilizing layer production, thereby increasing the practicability of the device.

[0086] Furthermore, by pulling the fixing block 14, the fixing block 14 drives the fixing rod 15 to move upward out of the adjustment slot 17, and simultaneously stretches the fixing spring 16, so that the first filter plate 12 can be pulled left and right at this time, so that the position of the filter holes on the first filter plate 12 can be adjusted, and the staggered space between the filter holes on the upper and lower sides can be adjusted, so that the particle size of the raw materials that can be filtered by the filter holes can be adjusted at will, and the adjustment is convenient, so that the screening box 3 can screen water-stabilizing layer production raw materials of different particle sizes, thereby increasing the applicability of the device and simultaneously increasing the practicality of the device.
