Description

Technical Field

[0001] This utility model belongs to the field of sand and gravel screening technology, and specifically relates to a sand and gravel dual-excitation vibration device. Background Technology

[0002] The sand and gravel dual-excitation vibration device is a high-efficiency equipment used for sand and gravel screening, conveying and processing. It is widely used in mining, building materials, chemical and other industries. This device generates compound vibration through two vibration sources (usually motor-driven vibrators), thereby achieving a more efficient material processing effect.

[0003] Existing dual-excitation vibratory sand and gravel devices use an exciter to generate a vibration source, enabling the equipment to produce the required vibration frequency and amplitude. Materials of different particle sizes are then screened through a screen. Springs buffer and support the entire vibratory device, reducing impact on the foundation structure and ensuring effective vibration transmission. This achieves vibratory screening of sand and gravel. However, in actual use, sand and gravel materials are typically fed into the inlet via a belt feeder, and then vibrated through a screen. The fixed feeding position of the belt feeder causes material to accumulate in one area on the screen, requiring time to disperse and screen, thus affecting the efficiency of vibratory screening of sand and gravel. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the existing technology by providing a double-excitation vibration device for sand and gravel, which can quickly and evenly distribute the conveyed sand and gravel during screening, so that the sand and gravel can be evenly spread on the screen, facilitating subsequent vibrating screening and effectively ensuring the screening efficiency of sand and gravel.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a sand and gravel dual-excitation vibration device, including a support, a vibration box mounted on the support, a feed hopper mounted on the vibration box, a mounting frame mounted on the support, a mounting sleeve mounted on the mounting frame, a discharge hopper mounted inside the mounting sleeve, symmetrically distributed rotating rods rotatably mounted on both inner walls of the support via rotating shafts, the bottom ends of the rotating rods being rotatably connected to the bulk hopper, a drive module mounted on the support for driving the bulk hopper to shake; the drive module includes a control box mounted on the outside of the mounting frame, symmetrically distributed rotating shafts rotatably mounted inside the control box, worm gears fixedly mounted on the outer arc surface of each rotating shaft, the rotating shafts being fixed to adjacent rotating shafts via couplings, multiple rotating seats inside the control box, worm gears rotatably mounted between adjacent rotating seats, the two worm gears being fixed to each other via couplings, the worm gears being meshed with adjacent worm gears; a motor is also mounted on the control box, the output shaft of the motor being fixed to adjacent worm gears via couplings.

[0006] As a further improvement of this utility model, a filter screen 1 is provided on the upper side of the inside of the vibration box, a filter screen 2 is provided in the middle of the vibration box, and a chute plate is provided on the lower side of the inside of the vibration box; a discharge hopper 1 that cooperates with the filter screen 1 is provided on the upper left side of the vibration box, a discharge hopper 2 that cooperates with the filter screen 2 is provided in the middle of the left side of the vibration box, and a discharge hopper 3 that cooperates with the chute plate is provided on the lower left side of the vibration box.

[0007] As a further improvement of this utility model, two symmetrically distributed exciters are provided at the lower end of the vibration box.

[0008] As a further improvement of this utility model, multiple fixing plates are provided on the lower side of the bracket, and fixing holes are provided on each fixing plate.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, the rotating shaft drives the rotating rod located on the shaft to oscillate back and forth. Since the rotating shaft, rotating rod and bulk hopper can form a parallelogram structure, the reciprocating oscillation of the rotating rod can drive the bulk hopper to oscillate back and forth continuously. The continuously oscillating bulk hopper is used to screen the sand and gravel.

[0011] Secondly, the motor's output shaft rotates in both directions, causing the worm gear connected to it to rotate in both directions. Through the coupling between the worm gears, the two worm gears rotate synchronously in both directions, which in turn drives the rotating rod to swing back and forth quickly and stably.

[0012] Third, the vibrator drives the vibrating box to vibrate, and the two vibrators cause the filter screen 1, filter screen 2 and chute plate inside the vibrating box to vibrate, so as to quickly screen the incoming sand and gravel.

[0013] Fourth, after the bolts are passed through the fixing holes, they are tightened by external tools, and then the bracket is fixed on the ground to stabilize the position of the bracket. This effectively prevents the position of the bracket from easily moving due to vibration during the screening of sand and gravel. Attached Figure Description

Detailed Implementation

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] like Figure 1 , 2 As shown, the device includes a support 101, a vibrating box 103 mounted on the support 101, a feeding hopper 110 mounted on the vibrating box 103, a mounting frame 112 mounted on the support 101, a mounting sleeve 201 mounted on the mounting frame 112, a discharge hopper 202 disposed inside the mounting sleeve 201, and symmetrically distributed rotating rods 203 mounted on both inner walls of the support 101 via rotating shafts. The bottom ends of the rotating rods 203 are rotatably connected to the bulk material hopper 204. The support 101 is also equipped with a drive module, which is used to drive the bulk material hopper 204 to shake.

[0022] like Figure 2 , 3 As shown, the drive module includes a control box 205 located on the outside of the mounting bracket 112. Symmetrically distributed rotating shafts 206 are rotatably arranged inside the control box 205. Worm gears are fixedly fitted onto the outer arc surface of each rotating shaft 206. The rotating shafts 206 are fixed to adjacent rotating shafts via couplings. Multiple rotating seats 207 are arranged inside the control box 205. A worm gear 208 is rotatably arranged between two adjacent rotating seats 207. Two worm gears 208 are fixed to each other via couplings, and each worm gear 208 meshes with an adjacent worm wheel. A motor 209 is also mounted on the control box 205. The output shaft of the motor 209 is fixed to the adjacent worm gear 208 via a coupling.

[0023] like Figure 2 , 4As shown, a filter screen 107 is provided on the upper side of the inside of the vibration box 103, a filter screen 108 is provided in the middle of the vibration box 103, and a chute plate 109 is provided on the lower side of the inside of the vibration box 103; a discharge hopper 104 that cooperates with the filter screen 107 is provided on the upper left side of the vibration box 103, a discharge hopper 105 that cooperates with the filter screen 108 is provided in the middle left side of the vibration box 103, and a discharge hopper 106 that cooperates with the chute plate 109 is provided on the lower left side of the vibration box 103.

[0024] like Figure 2 , 4 As shown, two symmetrically distributed exciters 111 are provided at the lower end of the vibration box 103.

[0025] In use, the output shaft of motor 209 rotates in both directions, causing the output shaft of motor 209 to drive the worm 208 connected to it to rotate in both directions. Through the coupling between the worms 208, the two worms 208 are driven to rotate synchronously in both directions. Through the meshing relationship between the worm 208 and the worm wheel, the rotating shaft 206 where the worm wheel is located is driven to rotate. The rotating shaft 206 drives the rotating rod 203 where the rotating shaft is located to swing back and forth. Since the rotating shaft, the rotating rod 203 and the bulk hopper 204 can form a parallelogram structure, the reciprocating swing of the rotating rod 203 can drive the bulk hopper 204 to continuously swing back and forth.

[0026] The vibrator 111 drives the vibrating box 103 to vibrate, which in turn causes the filter screen 107, filter screen 108 and chute plate 109 inside the vibrating box 103 to vibrate. Then, the sand and gravel to be vibrated and screened is conveyed into the hopper 202 by the belt conveyor, and then enters the bulk hopper 204 through the hopper 202. The bulk hopper 204, which is constantly shaking, makes the sand and gravel material evenly dispersed into the vibrating box 103 through the feed hopper 110, so that the sand and gravel material can be evenly spread on the filter screen 107. The vibrating filter screen 107, filter screen 108 and chute plate 109 are used to vibrate and screen the sand and gravel material, and then it is discharged through the discharge hopper 104, discharge hopper 205 and discharge hopper 306 respectively.

[0027] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, the lower side of the bracket 101 is provided with multiple fixing plates 102, each of which has fixing holes. In use, bolts are passed through the fixing holes and tightened with external tools to fix the bracket 101 to the ground, which can effectively prevent the position of the bracket 101 from easily moving due to vibration during use.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
