Referring to fig. 1, a sand making machine comprises a cylinder 1, wherein a feed inlet 2 is arranged at the top of the cylinder 1, the feed inlet 2 is arranged at the center of the top of the cylinder 1, and a cover plate is arranged at the feed inlet 2, so that the feed inlet 2 is conveniently closed after materials are added, and other foreign matters are prevented from entering the inside of the cylinder 1 or the materials in the cylinder 1 are prevented from being ejected from the feed inlet 2 during crushing; the bottom in the cylinder 1 is provided with a driving motor 3, the output end of the driving motor 3 is connected with a rotating shaft 4 in a transmission way, the rotating shaft 4 is vertically arranged, a crushing hammer 5 is arranged on the rotating shaft 4, the inner wall of the cylinder 1 is provided with a crushing bulge 6 opposite to the crushing hammer 5, a sieve plate 7 and a material collecting plate 8 are arranged in the cylinder 1 from top to bottom at intervals, the crushing hammer 5 is positioned above the sieve plate 7, a bearing is arranged at the joint of the rotating shaft 4 and the sieve plate 7, a fixed grinding disc 9 and a rotating grinding disc 10 are arranged below the sieve plate 7, the bottom surface of the fixed grinding disc 9 is attached to the top surface of the rotating grinding disc 10, the rotating grinding disc 10 and the rotating shaft 4 rotate coaxially, the side wall of the fixed grinding disc 9 is fixedly attached to the inner wall of the cylinder 1, the rotating shaft 4 penetrates through the fixed grinding disc 9, the joint of the rotating shaft 4 and the fixed grinding disc 9 is provided with a bearing, the fixed grinding disc 9 is provided with a feeding channel, the rotating grinding disc 10 is provided with a material leakage hole (not shown in the figure), the discharge gate 11 that corresponds with the board 8 that gathers materials is seted up to the lateral wall of barrel 1, and for the convenience of discharging the material, this board 8 slope that gathers materials sets up, and discharge gate 11 sets up the lower one side of the board 8 that gathers materials. The driving motor 3 of this embodiment is located album flitch 8 below, and pivot 4 passes album flitch 8 and upwards extends, and pivot 4 is equipped with the bearing with the junction of gathering flitch 8.

Through the aforesaid setting, this embodiment realizes on current system sand device's basis, form grinding mechanism through addding fixed abrasive disc 9 and rotation abrasive disc 10, after the material is smashed through crushing hammer 5 and crushing protruding 6 synergism, fall into feedstock channel through the prefilter of sieve 7, and along with feedstock channel gets into fixed abrasive disc 9 and rotate between the abrasive disc 10, it rotates under the drive of pivot 4 to rotate abrasive disc 10, thereby further grinding is carried out to the material between fixed abrasive disc 9 and the rotation abrasive disc 10, the material after the final grinding falls on album flitch 8 through the hourglass material hole, and finally discharge from discharge gate 11. Through grinding the crushed materials, the granularity of the finally obtained sand grains is smaller, and the sand grains are more uniform and fine.

Consider that after the material is put into the sand making machine, it is difficult to crush the large material only by the crushing hammer 5 and the crushing protrusion 6. Therefore, in the present embodiment, a pair of crushing rollers 12 is further disposed inside the barrel 1, and the crushing rollers 12 are rollers having a plurality of crushing teeth on the surface; the crushing roller 12 is located above the rotating shaft 4 and is opposite to the feed opening 2. So set up, the material that drops into through feed inlet 2 at first carries out preliminary broken back through crushing roller 12, smashes through smashing hammer 5 and crushing arch 6 again, and crushing effect is better. Meanwhile, in order to enable the primarily crushed materials to enter the area where the crushing hammer 5 is located more smoothly, a leakage hopper 13 is further arranged between the crushing roller 12 and the rotating shaft 4, and the higher side of the leakage hopper 13 is fixedly connected with the inner wall of the barrel 1. In addition, in order to enable the materials entering the area where the crushing hammer 5 is located to be distributed more uniformly, a material distributing table 14 in a circular truncated cone shape is arranged at one end, away from the driving motor 3, of the rotating shaft 4, and the material distributing table 14 is over against the outlet of the material leaking hopper 13. The material can be uniformly dispersed to the periphery as much as possible through the material distribution table 14, so that the crushing effect is further improved.

In the embodiment, in order to make the materials falling from the sieve plate 7 better fall between the fixed grinding disc 9 and the rotating grinding disc 10, the feeding channel comprises a first feeding channel 15 and a second feeding channel 16, the first feeding channel 15 is funnel-shaped, so that the materials are conveniently collected, and the materials are prevented from being stacked on the top surface of the fixed grinding disc 9; the second feed channel 16 is plural in number and communicates with the first feed channel 15; the plurality of second feeding channels 16 are arranged in the fixed grinding disc 9 at equal intervals, so that the materials falling into the fixed grinding disc 9 and the rotating grinding disc 10 are more uniformly distributed, and the grinding effect is better.

The crushing effect of the existing sand making machine is not good, and the materials with larger granularity can not be discharged in time after falling on the sieve plate 7. Therefore, in this embodiment, the sieve plate 7 is disposed obliquely, the side wall of the cylinder 1 is provided with a discharge opening 17, and the lower side of the sieve plate 7 corresponds to the discharge opening 17. When the material with larger granularity falls on the sieve plate 7, the material can be directly discharged from the discharge opening 17. Simultaneously, in order to facilitate carrying out the regrinding to the great material of granularity, be equipped with feed back 18 at the top of barrel 1, the outside of barrel 1 is equipped with transport mechanism 19, is equipped with feed back passageway 20 between bin outlet 17 and the transport mechanism 19, transport mechanism 19's output and feed back 18 intercommunication. The conveyor 19 of this embodiment can be, but is not limited to, a lifting auger. After the material that the granularity is great is discharged from bin outlet 17, roll to transport mechanism 19 in through feed back passageway 20, promote the material to feed back 18 by transport mechanism 19 again and get into barrel 1 inside and carry out the regrinding, realize the circulation breakage to the material, improve crushing effect greatly.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
