Description

Technical Field

[0001] The utility model belongs to the technical field of machine-made sand production, and specifically relates to machine-made sand grinding equipment. Background Art

[0002] Artificial sand refers to rock particles with smaller particle size that are processed through multiple steps by a sand making machine or other special sand making equipment. With the development of environmental protection concepts, in order to avoid excessive exploitation of natural resources such as natural river sand, artificial sand has become one of the important raw materials for modern engineering. According to different material requirements, different equipment can be selected to produce artificial sand of various specifications. The raw materials are easy to obtain, and can be processed from a variety of stones such as pebbles, limestone, granite, etc.

[0003] In the production process of artificial sand, a grinder is needed to grind the sand and gravel raw materials. Existing artificial sand grinders generally use rollers to extrude and grind the raw materials. While the energy loss is high, the coarseness of the artificial sand grinding cannot be adjusted, resulting in poor flexibility of the grinder and poor grinding effect. Utility Model Content

[0004] The purpose of the utility model is to provide a machine-made sand grinding device to solve the problems mentioned in the background technology.

[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0006] A machine-made sand grinding device comprises a base and a grinding barrel body, wherein a grinding device is installed inside the grinding barrel body;

[0007] A bracket is installed inside the grinding barrel body, and a conical disc is rotatably installed on the upper side of the bracket. The grinding device includes a conical grinding wheel, a universal joint is installed on the upper side of the conical grinding wheel, and the universal joint is fixedly connected to the center of the conical disc. A control rod colinear with the axis of the conical grinding wheel is fixed on the lower side of the conical grinding wheel. A grinding wall matching the conical grinding wheel is provided on the inner wall of the grinding barrel body, and a control component capable of controlling the rotation angle of the conical grinding wheel and being transmission-connected to the control rod is provided on the lower side of the conical grinding wheel.

[0008] The control component includes a rotating shaft that is slidably connected to the bottom of the grinding barrel body up and down, and the rotating shaft is also rotatably connected to the bottom of the grinding barrel body. A sleeve is sleeved on the outer side of the control rod, and the sleeve is hinged to the rotating shaft and eccentric to the rotating shaft. A telescopic transmission shaft is also connected to the lower side of the rotating shaft. A motor is installed on the upper side of the base, and the output end of the motor is transmission-connected to the telescopic transmission shaft. A round block is installed on the upper side of the telescopic transmission shaft, and a shift block rotatably connected to the round block is installed on the side of the round block. A slide rail is vertically installed on the side of the bottom, and the shift block is slidably connected to the slide rail up and down. A hydraulic rod is also installed on the lower side of the base, and the output end of the hydraulic rod is transmission-connected to the shift block.

[0009] A protective cover is installed on the upper side of the sleeve.

[0010] A cross-shaped plate is also installed on the upper side of the conical disc, and a plurality of impact bars distributed circumferentially and fixedly connected to the inner wall of the grinding barrel body are installed on the side of the conical disc.

[0011] An inclined bottom plate is installed at the bottom of the grinding barrel body, and a discharge port matching the bottom plate is opened at the bottom of the grinding barrel body.

[0012] An adjustable sieve plate assembly is inclined on the upper side of the bottom plate, and the adjustable sieve plate assembly includes a first sieve plate fixed to the barrel wall of the grinding barrel body, a coarse material opening matching the first sieve plate is opened on the side wall of the grinding barrel body, a second sieve plate is slidably installed on the lower side of the sieve plate, a screw is rotatably installed on the front side of the grinding barrel body, a handle is transmission-connected to the front side of the screw, and the screw is threadedly connected to the second sieve plate.

[0013] The cooperation between the conical grinding wheel and the grinding wall enables the conical grinding wheel to impact the raw material at the same time during grinding, so that the unit production volume is higher and the energy consumption of the equipment operation is reduced. At the same time, the control component can also control the change of the eccentricity of the conical grinding wheel. While the conical grinding wheel is rotating, changing the eccentricity of the conical grinding wheel can make the material be squeezed and ground to different degrees between the conical grinding wheel and the grinding wall, so as to adjust the grinding coarseness. The conical disc can make the raw material added to the inner side of the grinding barrel body dispersed evenly, so that the equipment grinds more evenly and improves the grinding effect. The cooperation of the hydraulic rod, the shift block, the rotating shaft and the sleeve makes the transmission component simple in structure and easy to operate while realizing the control of the grinding device. Troubleshooting and repair reduce manufacturing costs and improve equipment stability. The protective cover can prevent the ground machine-made sand from directly impacting the sleeve, thereby protecting it and extending its service life. When the grinding device is running, the motor drives the conical grinding wheel and the conical disc to rotate at high speed. The cross-shaped plate causes the material that contacts the conical disc to be thrown out by the high-speed rotating conical disc and hit the impact bar to achieve continued preliminary crushing of the material, thereby reducing the grinding difficulty of the grinding device to a limited extent and improving the grinding efficiency of the grinding equipment. The adjustable screen plate assembly can be adjusted to a suitable size according to needs. Machine-made sand that does not meet the grinding requirements cannot pass through the screen holes and is discharged from the coarse material port for secondary grinding, thereby improving the preparation quality of machine-made sand prepared by the grinder.

DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1-5 As shown, a machine-made sand grinding device comprises a base 2 and a grinding barrel body 1, and a grinding device is installed inside the grinding barrel body 1;

[0023] A bracket 3 is installed inside the grinding barrel body, and a conical disc 4 is rotatably installed on the upper side of the bracket 3. The grinding device includes a conical grinding wheel 5, a universal joint 6 is installed on the upper side of the conical grinding wheel 5, and the universal joint 6 is fixedly connected to the center of the conical disc 4. A control rod 7 colinear with the axis of the conical grinding wheel 5 is fixed on the lower side of the conical grinding wheel 5. A grinding wall 8 matching the conical grinding wheel 5 is provided on the inner wall of the grinding barrel body 1, and a control component that can control the rotation angle of the conical grinding wheel 5 and is transmission-connected to the control rod 7 is provided on the lower side of the conical grinding wheel 5;

[0024] The control component includes a rotating shaft 9 which is connected to the bottom of the grinding barrel body for sliding up and down. The rotating shaft 9 is also connected to the bottom of the grinding barrel body for rotation. A sleeve 10 is sleeved on the outer side of the control rod 7. The sleeve 10 is hinged to the rotating shaft 9 and is eccentric to the rotating shaft 9. A telescopic transmission shaft 11 is also connected to the lower side of the rotating shaft 9. A motor 12 is installed on the upper side of the base 2. The output end of the motor 12 is connected to the telescopic transmission shaft 11 for transmission. A round block 13 is installed on the upper side of the telescopic transmission shaft 11. A shift block 14 which is connected to the round block 13 for rotation is installed on the side of the round block 13. A slide rail 15 is vertically installed on the side of the bottom. The shift block 14 is connected to the slide rail 15 for sliding up and down. A hydraulic rod 16 is also installed on the lower side of the base 2. The output end of the hydraulic rod 16 is connected to the shift block 14 for transmission.

[0025] When the utility model is in use, the machine-made sand raw materials to be ground are added from the upper side of the grinding barrel body 1, and the control component controls the control rod 7 to make the conical grinding wheel perform precise and powerful rotation and swing motion around the universal joint 6 inside the grinding wall 8. Specifically, the conical grinding wheel 5 performs rotation and swing motion around the center point of the universal joint 6, and its motion trajectory is conical. This trajectory ensures that the material can be squeezed and ground in all directions inside the grinding wall 8.

[0026] The cooperation between the conical grinding wheel 5 and the grinding wall 8 enables the conical grinding wheel 5 to impact the raw material at the same time during grinding, so that the unit production volume is higher and the energy consumption of the equipment operation is reduced. At the same time, the control component can also control the change of the eccentricity of the conical grinding wheel 5. When the conical grinding wheel 5 rotates, changing the eccentricity of the conical grinding wheel 5 can make the material be squeezed and ground to different degrees between the conical grinding wheel 5 and the grinding wall 8, thereby adjusting the grinding coarseness. The conical disc 4 can make the raw material added to the inner side of the grinding barrel body 1 dispersed evenly, so that the equipment grinds more evenly and improves the grinding effect.

[0027] When the control component is working, the output shaft of the motor 12 drives the rotating shaft 9 to rotate, and the sleeve 10 eccentric to the rotating shaft 9 drives the conical grinding wheel 5 to perform a swinging motion. The hydraulic rod 16 is controlled to be retracted so that the shift block 14 drives the round block 13 to rise and fall, thereby achieving the purpose of changing the grinding angle of the conical grinding wheel 5. The retractable transmission shaft 11 is a prior art and can continuously transmit power when the rotating shaft 9 moves up and down.

[0028] The cooperation of the hydraulic rod 16, the shift block 14, the rotating shaft 9 and the sleeve 10 enables the transmission assembly to control the grinding device while making the structure of the transmission assembly simple, easy to troubleshoot and repair, reducing manufacturing costs and improving equipment stability.

[0029] A protective cover 17 is installed on the upper side of the sleeve 10 .

[0030] The protective sleeve can prevent the ground machine-made sand from directly impacting the sleeve 10, thereby protecting it and extending its service life.

[0031] A cross-shaped plate 25 is also installed on the upper side of the conical disc 4, and a plurality of impact bars 26 are installed on the side of the conical disc 4 and are distributed circumferentially and fixedly connected to the inner wall of the grinding barrel body.

[0032] When the grinding device is running, the motor 12 drives the conical grinding wheel 5 and the conical disc 4 to rotate at high speed. The cross-shaped plate 25 causes the material that contacts the conical disc 4 to be thrown out by the high-speed rotating conical disc 4 and hit the impact bar 26, thereby continuing the preliminary crushing of the material, thereby reducing the grinding difficulty of the grinding device to a limited extent and improving the grinding efficiency of the grinding equipment.

[0033] An inclined bottom plate 18 is installed at the bottom of the grinding barrel body 1 , and a discharge port 19 matching the bottom plate 18 is opened at the bottom of the grinding barrel body 1 .

[0034] The inclined bottom plate 18 guides the machine-made sand after grinding and finally discharges it from the discharge port 19 through the bottom plate 18 .

[0035] An adjustable sieve plate assembly is inclined on the upper side of the bottom plate 18, and the adjustable sieve plate assembly includes a first sieve plate 20 fixed to the barrel wall of the grinding barrel body, a coarse material opening 24 matching the first sieve plate 20 is opened on the side wall of the grinding barrel body 1, a second sieve plate 21 is slidably installed on the lower side of the sieve plate, a screw rod 22 is rotatably installed on the front side of the grinding barrel body, a handle 23 is transmission-connected to the front side of the screw rod 22, and the screw rod 22 is threadedly connected to the second sieve plate 21.

[0036] The first sieve plate 20 and the second sieve plate 21 can cooperate to form an adjustable sieve plate. By turning the handle 23 and the screw rod 22, the lower sieve plate can be controlled to move left and right to adjust the size of the sieve holes of the adjustable sieve plate assembly. The adjustable sieve plate assembly can be adjusted to a suitable size according to needs. The machine-made sand that does not meet the grinding requirements cannot pass through the sieve holes and is discharged from the coarse material port 24 for secondary grinding, thereby improving the preparation quality of the machine-made sand prepared by the grinder.

[0037] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
