DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 5 As shown, the utility model provides a particle raw material grinding device, including a chassis 1, a placing box 2 is fixedly installed on the top of the chassis 1, a motor 3 is fixedly installed on the front end of the chassis 1, a grinding arm 4 is fixedly sleeved on the output end of the motor 3, an extension plate 5 is fixedly installed on the left end of the grinding arm 4, a grinding net 6 is fixedly installed in the inner cavity of the chassis 1, an air box 7 is fixedly installed on the left end of the inner cavity of the chassis 1, a lifting plate 8 is slidably connected to the inner cavity of the air box 7, a bottom plate 9 is fixedly installed on the bottom end of the lifting plate 8, a pull-down spring 10 is sleeved on the middle part of the lifting plate 8, a one-way fixed pipe 11 and a one-way air inlet pipe 12 are fixedly installed on the right end of the air box 7, an exhaust pipe 13 is fixedly installed on the front end of the one-way fixed pipe 11, a blocking shaft 14 is slidably connected to the inner cavity of the exhaust pipe 13, an extension shaft 15 is slidably connected to the inner cavity of the one-way fixed pipe 11, a reset spring 16 is sleeved on the surface of the extension shaft 15, and a material blocking plate 17 and a magnet 18 are fixedly installed on the right ends of the extension shaft 15 and the blocking shaft 14 respectively;

[0021] During grinding, the air in the air box 7 is periodically sent into the one-way fixed tube 11 by utilizing the swing of the grinding arm 4, thereby achieving a continuous increase in the pressure in the one-way fixed tube 11, and continuously moving the extension shaft 15 to the right. When the baffle plate 17 is misaligned with the square hole, the raw material in the placement box 2 begins to feed. When the baffle plate 17 contacts the magnet 18, the magnet 18 pulls the blocking shaft 14 to move to relieve the pressure on the one-way fixed tube 11, and then the extension shaft 15 is reset to close the square hole, thereby achieving timed and quantitative addition of granular raw materials, avoiding excessive accumulation on the grinding mesh 6, and improving the grinding efficiency.

[0022] Among them, a hanging shaft 19 is fixedly installed at the bottom end of the bottom plate 9, and the bottom end of the hanging shaft 19 passes through the grinding mesh 6, and the shape of the bottom end of the hanging shaft 19 is "U"-shaped;

[0023] By installing the hanging shaft 19 on the bottom plate 9, when the grinding arm 4 swings and drives the extension plate 5 to hit the bottom plate 9, the bottom end of the hanging shaft 19 can be driven to move upward, and then the bottom end of the hanging shaft 19 hits the grinding mesh 6, causing vibration to the powdered raw materials on the grinding mesh 6, and the powdered raw materials are shaken into the collection box 21, so as to prevent the powdered raw materials from blocking the grinding mesh 6. There is no need to clean the grinding mesh 6, and it is simple and convenient to use.

[0024] Among them, two material guide plates 20 are fixedly installed in the inner cavity of the placement box 2, and a square hole is opened at the top of the chassis 1. The two material guide plates 20 are respectively located on the left and right sides of the square hole;

[0025] By providing two material guide plates 20 , the granular raw materials in the placement box 2 can be transported to the square holes, thereby preventing the granular raw materials from remaining in the placement box 2 .

[0026] A collection box 21 is placed at the bottom of the chassis 1, and the right end of the collection box 21 penetrates and extends to the right side of the chassis 1;

[0027] By placing the collecting box 21 to collect the powdered raw materials, centralized collection, transportation and processing can be achieved. The operation is simple and convenient, and the collecting box 21 can be directly pulled out to the right to be taken out.

[0028] The bottom surface of the extension plate 5 is in contact with the top surface of the grinding net 6, and the axis of the grinding net 6 is colinear with the axis of the output shaft of the motor 3;

[0029] This ensures that the extension plate 5 can grind the granular raw materials on the grinding net 6 when it swings.

[0030] The baffle plate 17 is located on the left side of the magnet 18, and both the baffle plate 17 and the magnet 18 are slidably connected to the top of the inner cavity of the chassis 1;

[0031] The magnet 18 and the side wall at the right end of the chassis 1 are both magnetic, and the magnetic poles of the two facing each other are the same, so that when the baffle plate 17 moves to the left, the magnet 18 can be pushed back to its original position by the repulsive magnetism.

[0032] The working principle and use process of this utility model:

[0033] When in use, a large amount of granular raw materials are poured into the placement box 2, and the motor 3 is started. The motor 3 drives the grinding arm 4 to rotate, and then drives the extension plate 5 to swing left and right periodically. When the extension plate 5 swings to the leftmost side, the bottom plate 9 is pushed upward, and then the air in the air box 7 is sent to the one-way fixed pipe 11. When the extension plate 5 swings to the right, the elasticity of the pull-down spring 10 pulls the lifting plate 8 down and resets it. At this time, the outside air is sucked into the air box 7 through the one-way air inlet pipe 12 for replenishment, and the air entering the one-way fixed pipe 11 will push the extension shaft 15 to move right continuously, thereby driving the material blocking plate 17 to move right;

[0034] When the baffle plate 17 moves to a position misaligned with the square hole, the granular raw materials will enter the chassis 1 and fall on the grinding net 6. At this time, the swinging extension plate 5 can grind the granular raw materials on the grinding net 6, and the powdered raw materials that are ground and qualified directly pass through the grinding net 6 and fall into the collection box 21.

[0035] When the baffle plate 17 moves to the right and contacts the magnet 18, the magnet 18 can drive the blocking shaft 14 to move to the right. When the left end of the blocking shaft 14 leaves the passage connecting the exhaust pipe 13 and the one-way fixed pipe 11, the gas in the one-way fixed pipe 11 is discharged through the exhaust pipe 13. At this time, the return spring 16 in the compressed state drives the one-way fixed pipe 11 to reset, closes the square hole, stops feeding, and realizes batch quantitative feeding of granular raw materials. At this time, the magnetism between the magnet 18 and the right side of the chassis 1 can push the magnet 18 back to reset.

[0036] When the bottom plate 9 moves upward, the hanging shaft 19 can be driven to move upward, so that the hanging shaft 19 hits the grinding net 6, generates vibration to the grinding net 6, and thus accelerates the falling of the powdered raw material.

[0037] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
