[0003] The traditional method of manually crushing the ingredients in a mortar and pestle has the following problems:

[0004] ① Manual operation is time-consuming and labor-intensive, making it difficult to meet the needs of multi-sample experiments.

[0005] ② Unstable force control leads to powder agglomeration or over-crushing, affecting the accuracy of characterization.

[0006] ③ Open environments are prone to introducing impurities.

[0007] To address the inconvenience of grinding during the preparation of experimental materials, we propose a pollution-resistant crusher based on the preparation of experimental materials. Utility Model Content

[0008] The purpose of this invention is to provide a pollution-resistant crusher based on experimental material preparation, in order to solve the problems of existing manual mortar and pestle crushing devices mentioned in the background art, namely: ① manual operation is time-consuming and laborious, making it difficult to meet the needs of multi-sample experiments; ② unstable force control leads to powder agglomeration or over-crushing, affecting the accuracy of characterization; ③ open environment easily introduces impurities.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a pollution-resistant crusher based on experimental materials, comprising a fixed base, a support frame, a mortar and pestle, and a crushing rod. Rubber pads are distributed in a square pattern below the fixed base. The support frame is fixedly installed on the upper end of the fixed base. An upper top plate is provided on the upper end of the support frame. Side glass and main glass are provided on the side of the support frame. A grinding assembly is fixedly installed on the upper end of the upper top plate. A driving assembly is provided below the grinding assembly. The driving assembly is rotatably connected to the fixed base. An operation panel is provided on the front end face of the fixed base.

[0010] The grinding assembly includes a second motor, a rotating shaft at the lower end of the second motor, a guide rod annularly arranged on the outer side of the rotating shaft, the guide rod being fixedly mounted on the top plate, a sliding sleeve movably sleeved on the rotating shaft, a spiral groove formed on the inner side of the sliding sleeve, the guide rod being movably inserted into the sliding sleeve, a lever block arranged on the outer side of the rotating shaft, the lever block being slidably connected inside the spiral groove, a support rod at the lower end of the rotating shaft, the support rod being connected to the crushing rod by a pin, the crushing rod having a sliding groove formed on it, the pin block being slidably connected inside the sliding groove, and the crushing rod being connected to the sliding sleeve by a connecting rod.

[0011] The driving assembly includes a motor, a rotating disk at the upper end of the motor, a lower clamping plate on the rotating disk, a clamping block arranged in a ring on the lower clamping plate, an upper clamping plate at the lower end of the mortar, a clamping groove arranged in a ring on the lower end face of the upper clamping plate, and the clamping block engaging inside the clamping groove.

[0017] Preferably, the mortar and the rotating shaft are collinear, and the rotating shaft is located directly above the mortar.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This anti-pollution crusher based on experimental materials, by setting grinding and driving components inside the glass protective cover and fixed base, utilizes the cooperation between the grinding and driving components. After motor one and motor two are turned on, the mortar and crushing rod can rotate. At the same time, through the rotation of the shaft, the paddle moves in a ring. Since the paddle always slides inside the spiral groove, and the sliding sleeve with the spiral groove is guided by the guide rod, the sliding sleeve can only move upward or downward along the axis of the shaft during the rotation of the shaft. When the sliding sleeve moves upward or downward along the axis of the shaft, the connecting rod can make the crushing rod swing around the connection point of the pin rod. Thus, during the rotation of the mortar, the swing angle of the crushing rod is continuously changed, which further improves the grinding effect of the experimental materials in the mortar and stabilizes the force control.

[0020] 2. This type of anti-pollution crusher based on experimental materials can facilitate the replacement of mortars through the interlocking of the upper and lower clamping plates, thus meeting the needs of multi-sample experiments.

[0021] 3. This anti-pollution crusher based on experimental material preparation uses an inert gas inlet pipe to fill the inside of the glass protective cover to reduce sample oxidation, further improving the anti-pollution performance of the crusher and preventing the introduction of impurities into the open environment, which could lead to contamination of the experimental materials, thus further ensuring the preparation effect of the experimental materials.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example: Please refer to Figure 1-5 This utility model provides a technical solution: a pollution-resistant crusher based on experimental material preparation, including a fixed base 1, a support frame 2, a mortar 8 and a crushing rod 9. Rubber pads 12 are distributed in a square shape below the fixed base 1. By setting the rubber pads 12 in a square shape below the fixed base 1, the vibration of the experimental material preparation crusher can be reduced and the stability of the crusher can be improved.

[0030] Furthermore, the support frame 2 is fixedly installed on the upper end of the fixed base 1, and the upper end of the support frame 2 is provided with an upper top plate 3. Both the support frame 2 and the upper top plate 3 are made of steel structure. The use of steel structure for the support frame 2 and the upper top plate 3 can facilitate the support and fixation of other structures.

[0031] Side glass 4 and main glass 5 are provided on the side of the supporting frame 2. The side glass 4 and the supporting frame 2 are connected by screws, while the main glass 5 is slidably connected to the top plate 3. When the experimental material is placed into the mortar 8, it can be moved through the mortar as shown in the figure. Figure 1 The sliding main glass 5 shown in the diagram facilitates the insertion of experimental materials.

[0032] Please see Figure 1 and Figure 2 A grinding component 6 is fixedly installed on the upper end of the top plate 3. A driving component 7 is provided below the grinding component 6. The driving component 7 is rotatably connected to the fixed base 1. An operation panel 11 is provided on the front end face of the fixed base 1.

[0033] Specifically, the grinding assembly 6 includes a second motor 61, which is connected to a control switch via wires. A rotating shaft 62 is located at the lower end of the second motor 61. The mortar 8 and the rotating shaft 62 are collinear, with the rotating shaft 62 positioned directly above the mortar 8. A guide rod 63 is annularly arranged on the outer side of the rotating shaft 62, with the guide rod 63 parallel to the center line of the rotating shaft 62. The guide rod 63 is fixedly mounted on the upper top plate 3. A sliding sleeve 64 is movably sleeved on the rotating shaft 62. A spiral groove 65 is formed on the inner side of the sliding sleeve 64. The guide rod 63 is movably inserted into the sliding sleeve 64. A lever 66 is provided on the outer side of the rotating shaft 62, slidingly connected inside the spiral groove 65. The spiral groove 65 is a closed groove, and the width of the lever 66 is equal to the width of the spiral groove 65. After the second motor 61 is turned on, the rotating shaft 62 can be rotated. After the rotating shaft 62 rotates, the toggle block 66 can move in a ring. Since the toggle block 66 always slides inside the spiral groove 65, and the sliding sleeve 64 with the spiral groove 65 is guided by the guide rod 63, at this time, during the rotation of the rotating shaft 62, the sliding sleeve 64 can only move upward or downward along the axis of the rotating shaft 62.

[0034] Furthermore, a support rod 68 is provided at the lower end of the rotating shaft 62. The support rod 68 and the crushing rod 9 are connected by a pin 92. The crushing rod 9 has a sliding groove 91, and the pin 92 is slidably connected in the sliding groove 91. The crushing rod 9 and the sliding sleeve 64 are connected by a connecting rod 67. The connecting rod 67, the sliding sleeve 64, and the crushing rod 9 are all connected by pins. When the sliding sleeve 64 moves upward or downward along the axial direction of the rotating shaft 62, the connecting rod 67 allows the crushing rod 9 to swing around the connection point of the pin 92. This continuously changes the swing angle of the crushing rod 9 during the rotation of the mortar 8, further improving the grinding effect of the experimental material in the mortar 8.

[0035] Furthermore, the drive assembly 7 includes a first motor 71, which is connected to a control switch via wires. The first motor 71 is located below the second motor 61, and their centers are collinear. A rotating disk 72 is mounted on the upper end of the first motor 71, and a lower clamping plate 73 is mounted on the rotating disk 72. A clamping block 74 is arranged in a ring on the lower clamping plate 73. An upper clamping plate 81 is mounted on the lower end of the mortar 8, and a groove 82 is arranged in a ring on the lower end face of the upper clamping plate 81. The clamping block 74 engages with the groove 82. When the first motor 71 is turned on, the rotating disk 72 rotates, which in turn drives the lower clamping plate 73 to rotate. By engaging the mortar 8 on the lower clamping plate 73, the mortar 8 can rotate. With the assistance of the grinding assembly 6, the experimental material inside the mortar 8 can be quickly ground. The engagement method using the clamping block 74 and the groove 82 facilitates the replacement of the mortar 8, making it easier to clean and replace.

[0036] In this embodiment, an air inlet pipe 31 is provided on the upper top plate 3, and a plug is provided on the air inlet pipe 31. In order to improve the sealing of the experimental material during grinding, the plug can be removed, and inert gas can be introduced into the inside of the glass protective cover through the air inlet pipe 31 to reduce sample oxidation. This further improves the anti-contamination performance of the crusher.

[0037] Working principle: This type of anti-pollution crusher, based on experimental materials, operates by sliding the main glass 5, such as... Figure 1 In the indicated state, place the experimental material into the mortar 8 and close the main glass 5; turn on motor 1 71 and motor 2 61. After motor 2 61 is turned on, the rotating shaft 62 can rotate. After the rotating shaft 62 rotates, the toggle block 66 can make a circular motion. Since the toggle block 66 always slides inside the spiral groove 65, and the sliding sleeve 64 with the spiral groove 65 is guided by the guide rod 63, at this time, during the rotation of the rotating shaft 62, the sliding sleeve 64 can only move upward or downward along the axis of the rotating shaft 62. When the axial direction of 62 moves upward or downward, the connecting rod 67 enables the crushing rod 9 to swing and rotate around the connection point of the pin rod 92, thereby continuously changing the swing angle of the crushing rod 9 during the rotation of the mortar 8. After the motor 71 is turned on, the rotating disk 72 can rotate, which in turn drives the lower clamping plate 73 to rotate. By clamping the mortar 8 onto the lower clamping plate 73, the mortar 8 can rotate. Combined with the swing of the crushing rod 9, the effect and efficiency of grinding the experimental materials are further improved.

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