Description

Technical Field

[0001] The utility model belongs to the technical field of material crushing, and particularly relates to a sealed sample-making crushing bowl. Background Art

[0002] During the production process of other granular products such as expanded clay sand, the materials need to be crushed and granulated. In order to ensure product quality, it is necessary to first produce a small amount in the laboratory, and then carry out mass production after meeting the standards. In the prior art, laboratory crushing is completed with a small crusher. Its structure is similar to the high-efficiency tile grinder with publication number CN215353886U. The crushing bowl it uses consists of a bowl body, a striking ring and a striking block. The exciting force is generated by a motor drive, forcing the striking ring and the striking block to perform centrifugal motion, and the tiles in the bowl body are squeezed and crushed into powder. However, when the powder needs to be poured out, the entire crushing bowl needs to be taken out from the grinder, and then the powder is poured out. Due to the heavy weight of the crushing bowl, it is inconvenient to take. Utility Model Content

[0003] The utility model aims to overcome the defect of complicated pulverizing process in the prior art and provide a sealed sample preparation pulverizing bowl.

[0004] The utility model provides a sealed sample preparation and crushing bowl, comprising a bowl body and a bowl cover, wherein the bowl body and the bowl cover are detachably buckled and connected, a crushing liner is arranged inside the bowl body, and the bottom and the surrounding side of the crushing liner are both in contact with the inner wall of the bowl body;

[0005] A limiting column is arranged at the center of the crushing liner, and a plurality of first striking blocks and a second striking block are arranged inside the crushing liner. A circular hole is opened at the bottom of the second striking block, and the limiting column is inserted into the circular hole.

[0006] A further solution is that the top of the bowl body is a boss structure, and the inner wall of the peripheral side of the bowl cover and the boss structure form a sealing pair.

[0007] A further solution is that the diameter of the circular hole of the second striking block is 2-4 times the diameter of the limiting column.

[0008] A further solution is that a slide groove is provided on the inner wall of the bowl body, a slide rail adapted to the slide groove is provided on the outer side of the crushing liner, and the slide groove is engaged with the slide rail.

[0009] A further solution is that the first striking block is located on the peripheral side of the second striking block.

[0010] A further solution is that a crushing plate is provided inside the bowl cover, and when the bowl body and the bowl cover are in a buckled state, the crushing plate abuts against the crushing liner.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model has a crushing liner inside the bowl body, and the striking block is arranged on the crushing liner. After the crushing is completed, there is no need to take the whole bowl body out of the crushing device, and only the crushing liner needs to be taken out to pour out the powder, thereby improving the crushing efficiency.

[0013] The utility model arranges a plurality of first striking blocks on the periphery of the second striking block. When the motor drives the bowl body to rotate, since the round hole of the second striking block is sleeved on the limiting column, the second striking block makes eccentric circular motion along the limiting column, and the first striking block makes centrifugal motion. The second striking block and the first striking block squeeze and collide with each other to complete the crushing, which increases the number of collision and squeezing times compared with traditional striking blocks and striking rings.

[0019] In order to make the purpose, technical solution, design method and advantages of the utility model clearer, the utility model is further described in detail through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] like Figure 1 and Figure 3 As shown, the utility model provides a sealed sample preparation and crushing bowl, including a bowl body 1 and a bowl cover 6, wherein the bowl body 1 and the bowl cover 6 are detachably snap-fitted and connected, the top of the bowl body 1 is a boss structure, and the inner wall of the peripheral side of the bowl cover 6 forms a sealing pair with the boss structure, which is suitable for sealed sample preparation in a laboratory.

[0021] In order to facilitate the removal of the crushed powder, a crushing liner 2 is provided inside the bowl body 1, and the bottom and the surrounding side of the crushing liner 2 are in contact with the inner wall of the bowl body 1. In order to avoid relative rotation between the crushing liner 2 and the bowl body 1, in this embodiment, Figure 2As shown, a slide groove 7 is also provided on the inner wall of the bowl body 1, and a slide rail 8 adapted to the slide groove 7 is provided on the outer side of the crushing liner 2, and the slide groove 7 is engaged with the slide rail 8. A limiting column 3 is provided at the center position of the crushing liner 2, and a plurality of first striking blocks 4 and a second striking block 5 are also provided inside the crushing liner 2, wherein the first striking block 4 is located around the second striking block 5. A circular hole is provided at the bottom of the second striking block 5, and the limiting column 3 is inserted into the circular hole. When the motor drives the bowl body 1 to rotate, since the circular hole of the second striking block 5 is sleeved on the limiting column 3, the second striking block 5 performs an eccentric circular motion along the limiting column 3, and the first striking block 4 performs a centrifugal motion, and the second striking block 5 and the first striking block 4 squeeze and collide with each other to complete the crushing, which increases the number of collisions and squeezes compared with traditional striking blocks and striking rings.

[0022] In order to ensure that the second striking block 5 can rotate smoothly, the diameter of the circular hole should be larger than the diameter of the limiting column 3. In order to further ensure the collision rate between the second striking block and the first striking block, in this embodiment, the diameter of the circular hole of the second striking block 5 is 3 times the diameter of the limiting column 3.

[0023] In order to ensure the service life of the crushing bowl, a crushing plate is arranged inside the bowl cover 6, wherein the crushing lining 2 and the crushing plate are both made of high-hardness materials, which can be specifically determined according to the hardness of the material to be crushed, and when the bowl body 1 and the bowl cover 6 are in a buckled state, the crushing plate abuts against the crushing lining 2.

[0024] The embodiments of the present invention have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or technical improvements in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
