[0035] In the description of the present application, the words such as arrangement, installation, connection and the like should be understood in a broad sense, and the specific meanings of the words in the present application can be determined by the person skilled in the art in combination with the specific content of the technical solution, unless otherwise explicitly limited.

[0036] With reference to Figures 1 to 3 The present application discloses a grinding adapter assembly, which comprises a mounting seat 100, a grinding pipe 200, a pipe cover 300 and an elastic member 400. The mounting seat 100 is provided with a plurality of mounting holes 110. The mounting seat 100 is circularly arranged, and can also be arranged in a square or an ellipse. The plurality of mounting holes 110 are uniformly distributed around the circumference of the mounting seat 100. The middle part of the mounting seat 100 is provided with an outer connecting hole 120, which is used for connecting an exciter.

[0037] The outer peripheral wall of the grinding pipe 200 is provided with a clamped part 210. The grinding pipe 200 is placed in the mounting hole 110, and the clamped part 210 abuts against the mounting seat 100. The pipe opening 230 of the grinding pipe 200 is arranged upward. The pipe body below the clamped part 210 is threadedly connected with the mounting hole 110. The inner bottom of the grinding pipe 200 is provided with a first buffer recess 220.

[0038] The pipe cover 300 comprises an outer cover 310 and an inner cylinder 320. The outer cover 310 and the inner cylinder 320 have a gap 330 therebetween. A sealing ring 331 is embedded in the gap 330. The inner peripheral wall of the outer cover 310 is threadedly connected with the outer peripheral wall of the pipe opening 230. The inner cylinder 320 is inserted into the pipe opening 230. The sealing ring 331 abuts against the upper end edge of the pipe opening 230. The inner cylinder 320 is provided with a second buffer recess 321.

[0039] The elastic member 400 is arranged between the clamped part 210 and the mounting seat 100. One end of the elastic member 400 abuts against the mounting seat 100, and the other end of the elastic member 400 abuts against the clamped part 210.

[0040] It should be noted that at present, the grinding tube 200 used by the detection laboratory is mainly made of plastic, the bottom of the grinding tube 200 is flat, and the inner bottom of the tube cover 300 is also flat, so that the grinding ball has strong impact force on the bottom of the grinding tube 200 during vertical reciprocating vibration, and therefore a certain taper is arranged on the inner bottom of the grinding tube 200 to facilitate the concentration of the sample and reduce the impact of the reciprocating grinding particles, thereby improving the grinding effect. The outer part of the previous grinding tube is smooth and flat, and there is no structure for connecting with the exciter, so an additional fixing structure needs to be added at the placement position of the exciter, which increases the overall weight of the moving structure and generates more vibration and noise, affecting the service life of the whole grinding device; at the same time, the ordinary grinding tube does not have an independent clamping structure, and when the cap is tightened on the automatic or semi-automatic exciter, the clamping may slip, because the clamping is generally performed by a mechanical hand, so the probability of slipping between the mechanical hand and the smooth tube wall is relatively high; in addition, the inner top surface of the general tube cover 300 is flat, and there is no effective buffer structure, so a thicker structure is needed to provide the anti-impact ability, which increases the overall weight of the moving structure and thus brings additional vibration.

[0041] It should be understood that the diameter of the mounting table 140 is slightly smaller than the diameter of the clamped part 210, so as to avoid interference between the clamping jaw and the 110 part when the clamping jaw grabs the clamped part 210. The elastic member 400 and the sealing ring 331 at the tube cover 300 are usually pre-installed on the tube body and the tube cover 300. The function of the elastic member 400 is to buffer and prevent the grinding tube 200 from sliding out of the mounting seat 100.

[0042] In some embodiments, the grinding tube 200 and the tube cover 300 are made of metal or ceramic and other temperature-resistant materials, so that the sample can be ground in a wider temperature treatment range.

[0043] It should be understood that the mounting seat 100 is arranged to combine the grinding pipe 200 as a whole to form a grinding adapter assembly, which has simple structure and is convenient to use, the threaded connection structure improves the stability during the vibration grinding process, avoids the grinding pipe 200 from slipping off during vibration, the first buffer recess 220 and the second buffer recess 321 are arranged in cooperation, which can reduce the impact force of the grinding ball on the grinding pipe 200 when the grinding ball moves, the lateral component force generated when the grinding ball hits the first buffer recess 220 or the second buffer recess 321 can also act on the grinding sample, the first buffer recess 220 or the second buffer recess 321 is arranged in vertical opposition, so that the impact force of grinding is always confined in the space of the grinding pipe 200, ensuring that the vibration energy does not overflow, improving the grinding effect, the elastic member 400 is arranged to fill the gap between the grinding pipe 200 and the clamped part 210, the extrusion deformation and friction force of the elastic member 400 can stably connect the grinding pipe 200 and the clamped part 210, so that the whole adapter assembly can improve the assembly accuracy and device operation stability in the automatic or semi-automatic scene, which helps to improve the work efficiency and improve the grinding effect.

[0044] It should be pointed out that the threaded connection structure can be differentiated in specification according to the impact force generated during grinding, the economic efficiency of the grinding pipe 200 as consumables is improved, the external connecting hole of the pipe adapter is connected with the structure providing driving force; the grinding pipe 200 and the mounting seat 100 can be made into a split structure, which is convenient to replace the frequently used and worn threaded structure, and can also be compatible with grinding pipes 200 of different diameters, enriching the use scene of the grinding device and improving the economic efficiency of use.

[0045] In some embodiments, after the external connecting hole 120 is connected with the main shaft of the exciter, the internal mounting hole 110 of the mounting table 140 is locked by a screw, the straight hole has a gap expanding from top to bottom between the narrowed grinding pipe 200 and the pipe body, which can present a certain stepwise attenuation of the connection force between the grinding pipe 200 and the mounting hole 110 from top to bottom, cooperates with the first buffer recess 220 and the second buffer recess 321 arranged in opposition, and restricts the vibration energy in the grinding pipe 200, so as to improve the grinding efficiency and make the grinding more sufficient, the vibration amplitude of the relatively lower part of the grinding pipe 200 is larger, and the vibration amplitude of the relatively upper part of the grinding pipe 200 is smaller, which can ensure the secondary vibration and the connection stability.

[0046] Reference Figure 2 and Figure 3The mounting seat 100 comprises a support plate 130 and a mounting table 140, the support plate 130 is circularly arranged, and the support plate 130 can also be arranged in a square or an ellipse, the mounting table 140 is provided with a plurality of mounting tables 140 which are uniformly distributed around the circumference of the support plate 130, the mounting table 140 protrudes out of the support plate 130, the mounting hole 110 is vertically and penetratingly arranged on the mounting table 140, the elastic member 400 is arranged between the mounting table 140 and the clamped part 210, and the clamped part 210 is used for abutting against the mounting table 140; the mounting table 140 arranged can avoid the interference between the mechanical hand and the support plate 130, and can improve the strength of the threaded connection structure; it can be understood that, because the vertical length of the mounting table 140 is arranged, the threads in the mounting hole 110 are more, the threaded connection part contacts more, the connection is more compact, and the connection stability and the structural strength are higher.

[0047] In some embodiments, the two ends of the mounting table 140 protrude out of the two end plate surfaces of the mounting seat 100 respectively, a chamfer structure 150 is arranged at the connection position of the mounting table 140 and the support plate 130, and the chamfer structure 150 arranged can reduce the stress concentration at the connection position of the mounting table 140 and the support plate 130, and improve the structural strength; the clamped part 210 is arranged in a ring shape, and the clamped part 210 protrudes out of the outer circumferential wall of the grinding pipe 200; the structure is uniform, and the clamped part 210 is convenient to clamp and install; the outer edge of the clamped part 210 is provided with anti-skid lines, and the anti-skid lines arranged are convenient for the clamped part 210 to be clamped by the mechanical hand.
