Technical Field
[0001] The utility model relates to the technical field of sand and gravel crushers, and more specifically, to a sand and gravel crusher with a grading function. Background Art
[0002] Sand and gravel materials refer to the general name of local building materials such as sand, pebbles, crushed stones, block stones, strip stones, and dressed stones. It is the main building material for structures such as concrete and masonry in infrastructure projects. During the production and processing of sand and gravel materials, crushers are needed to crush them. However, the existing crushers have relatively single functions and can only perform crushing work on sand and gravel materials. After the sand and gravel materials are crushed and discharged, screening equipment is still needed to screen them, which is not only time-consuming and laborious but also further affects work efficiency. Therefore, there is an urgent need for a sand and gravel crusher with a grading function. Summary of the Utility Model
[0003] 1. Technical problems to be solved:

The crushed material falls from the discharge port of the crushing box onto the buffer member, buffering the impact force of the falling crushed material. And under the linear vibration of the vibrator, vibrations with a certain frequency and amplitude are generated, prompting the crushed material carried above the first sieve mesh to have the same vibration frequency and amplitude. Thus, due to the different mesh diameters of the first sieve mesh and the second sieve mesh, as well as the settings of vibration and inclined plane, the crushed material is classified and separated, which is beneficial for subsequent personnel to use them separately or to crush the crushed material with a larger diameter again, greatly improving the work efficiency of personnel.

[0008] The screening assembly includes a screening base arranged below the crushing box. A first spring is respectively installed between the side end of the screening base and each connecting bracket. A vibrator is installed at the lower end of the screening base. A buffer member, a first sieve mesh, a second sieve mesh, and a screening plate are sequentially installed between the inner walls of the screening base from top to bottom.
[0009] A further improvement lies in that: the driving end of one of the crushing rollers penetrates to the outside of the crushing box, and a motor is installed at one end of the external frame. A transmission belt is sleeved between the output end of the motor and the driving end outside the crushing roller.
[0010] A further improvement lies in that: the buffer is located on the upper side of the first screening mesh, the slope at the top of the buffer is opposite to the slope direction of the first screening mesh, and there are gaps between the buffer, the first screening mesh, the second screening mesh and the screening plate.
[0011] A further improvement lies in that: the buffer includes a buffer base fixedly connected between the inner walls of the top side of the screening base. A buffer plate is arranged between the inner walls of the buffer base, and a plurality of drag reduction members are arranged between the upper and lower inner walls of the buffer plate and the buffer base.
[0012] A further improvement lies in that: the drag reduction member includes a connecting seat one and a standing seat fixedly connected to the inner bottom wall of the buffer base. The standing seat is located on one side of the connecting seat one. A connecting rod one is rotatably connected between the inner walls of the connecting seat one.

[0014] 3. Beneficial effects:
[0015] Adopting the technical solution provided by the present utility model, compared with the prior art, it has the following beneficial effects:
[0016] The present utility model is reasonably designed. Personnel put the sand and gravel materials to be crushed into the crushing box. Then, driven by the motor, the driving end on one side of the crushing roller is synchronously rotated by the transmission belt, so as to prompt the two crushing rollers to continuously carry out the crushing work on the sand and gravel materials;
[0017] In the present utility model, after the crushing of sand and gravel materials, the crushed materials fall from the discharge opening of the crushing box onto the buffer member, and the impact force of the falling crushed materials is buffered. Moreover, under the inclined plane of the buffer member, the sand and gravel materials fall from above one side of the sieving base onto above the first sieving mesh. Finally, under the linear vibration of the vibrator, vibrations with a certain frequency and amplitude are generated, and under the connection of the first spring, the crushed materials carried above the first sieving mesh are caused to generate the same vibration frequency and amplitude. Thus, due to the different mesh diameters of the first sieving mesh and the second sieving mesh, and the settings of vibration and inclined plane, the crushed materials are classified and separated, which is conducive to the subsequent classification and use by personnel or the re - crushing of the crushed materials with larger diameters, greatly improving the work efficiency of personnel.

[0033] Please refer to Figures 1-4 , a sand and gravel crusher with a grading function, including a crushing box 1. A built - in frame 2 is fixedly connected to the side end of the crushing box 1. Two mutually meshing crushing rollers 3 are installed between the inner walls of the crushing box 1. A plurality of evenly distributed connecting brackets 5 are fixedly connected to the side end of the built - in frame 2. A screening assembly 6 is provided below the feeding port of the crushing box 1;
[0034] The screening component 6 includes a screening base 61 provided at the lower side of the crushing box 1. One end of a spring 7 is respectively installed between the side end of the screening base 61 and each connecting bracket 5. A vibrator 8 is installed at the lower end of the screening base 61. A buffer member 65, a first screening mesh 62, a second screening mesh 63, and a screening plate 64 are sequentially installed between the inner walls of the screening base 61 from top to bottom.
[0035] More specifically, the driving end of one crushing roller 3 penetrates to the outside of the crushing box 1. One end of the external frame 2 is provided with a motor 4, and a transmission belt is sleeved between the output end of the motor 4 and the driving end outside the crushing roller 3.
[0036] More specifically, the buffer member 65 is located above and on one side of the first screening mesh 62. The inclined surface at the top of the buffer member 65 is in the opposite direction to the inclined surface of the first screening mesh 62, and there are gaps between the buffer member 65, the first screening mesh 62, the second screening mesh 63, and the screening plate 64.
[0037] During the use of this solution, to avoid the cumbersome steps of manually using screening equipment to finely screen the existing sand and gravel materials after crushing, in this embodiment, the operator puts the sand and gravel materials to be crushed into the crushing box 1. Then, driven by the motor 4, the driving end on one side of the crushing roller 3 is synchronously rotated by the transmission belt, so as to prompt the two crushing rollers 3 to continuously carry out the crushing work on the sand and gravel materials.
[0038] After the sand and gravel materials are crushed, the crushed materials fall from the discharge port of the crushing box 1 onto the upper part of the buffer member 65, and the impact force of the falling crushed materials is buffered. And under the inclined surface of the buffer member 65, the sand and gravel materials fall from above one side of the screening base 61 onto the upper part of the first screening mesh 62. Finally, under the linear vibration of the vibrator 8, vibrations with a certain frequency and amplitude are generated, and under the connection of the spring 7, the crushed materials carried above the first screening mesh 62 generate the same vibration frequency and amplitude. Thus, due to the different mesh diameters of the first screening mesh 62 and the second screening mesh 63, as well as the settings of the vibration and the inclined surface, the crushed materials are classified and separated, which is beneficial for subsequent classification use by the operator or re-crushing of the crushed materials with a larger diameter, greatly improving the work efficiency of the operator.
[0039] Finally, the classified crushed materials can be provided with a receiving bucket on one side of the feeding ends of the first screening mesh 62, the second screening mesh 63, and the screening plate 64 for collecting each level of crushed materials.
[0040] Please refer to Figures 1-3 , the buffer member 65 includes a buffer base 651 fixedly connected between the inner walls of the top side of the screening base 61. A buffer plate 652 is arranged between the inner walls of the buffer base 651, and a plurality of drag reduction members 653 are arranged between the upper and lower inner walls of the buffer plate 652 and the buffer base 651.
[0041] During use of the present solution, the crushed materials first fall from the discharge port of the crushing box 1 to the buffer 65 for buffering, and then are caused to slide downward continuously by the inclined surface and the vibration of the vibrator 8, so that they fall to the side of the highest surface of the screen 1 62, and then with the continuous vibration of the vibrator 8, the small particles and fine sand-grade crushed materials can pass through the screen 1 62 and fall to the surface of the screen 2 63. As the mesh size of the screen 2 63 decreases, the small particles of the crushed materials are retained again, so that the fine sand-grade crushed materials finally fall to the surface of the screen plate 64 for transportation, and finally the three-level screening of the crushed materials is realized, which greatly facilitates the use of the crushed materials by personnel and reduces their labor burden.
[0042] See also Figures 1-4 The drag reducing member 653 comprises a connecting seat 1 6531 and a standing seat 6533 fixedly connected to the inner bottom wall of the buffer base 651, the standing seat 6533 is located at one side of the connecting seat 1 6531, a connecting rod 1 6532 is rotatably connected between the inner walls of the connecting seat 1 6531, a convex hole 6534 is opened inside the standing seat 6533, a convex block 6535 is movably connected between the inner walls of the top end of the convex hole 6534, and a spring 2 6536 is fixedly connected between the convex block 6535 and the inner wall of one side of the convex hole 6534;
[0043] The bottom end of the buffer plate 652 is also fixedly connected to a second connecting seat 6537, and a second connecting rod 6538 is rotatably connected between the inner walls of the second connecting seat 6537. The middle inner wall of the second connecting rod 6538 is rotatably connected to one end of the first connecting rod 6532. A connecting rod 6539 is rotatably connected between the bottom inner walls of the second connecting rod 6538, and the connecting rod 6539 extends to both sides of the bottom end of the convex block 6535.
[0044] During the use of this solution, when the crushed sand and gravel fall from the discharge port of the crushing box 1 to the surface of the buffer member 65, the sand and gravel are first carried by the buffer plate 652. Due to the impact force during the discharge, the buffer plate 652 moves downward and contacts the connecting rod 2 6538 on the lower side to rotate. Since one end of the connecting rod 6539 penetrates into the interior of the convex block 6535, when the connecting rod 2 6538 rotates, it can push the convex block 6535 to move to the side of the spring 2 6536 and press it, thereby buffering the impact force from the falling of the crushed material, and preventing the crushed material from falling directly on the surface of the screen 1 62 to cause its deformation, and the connecting rod 1 6532 can reinforce and support the whole on the other side.
[0045] Finally, after the impact force ends, the second spring 6536 rebounds under the action of its elastic potential energy, and thus the repeated buffering work of the crushed materials can be carried out.
[0046] The above-described embodiments merely represent certain implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model; it should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model; therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
