Description

Technical Field

[0001] This utility model relates to a laboratory-made dried plant material pulverizing device. Background Technology

[0002] A pulverizer is a crucial piece of equipment in condiment processing. However, when raw materials vary in size, the resulting pulverized particles are often uneven. Existing pulverizing devices simply drop the pulverized raw materials directly into the discharge hopper, lacking a screening function to remove larger particles for secondary processing. This uneven particle size negatively impacts product quality. For example, patent CN213590745U discloses a condiment pulverizer comprising a feed hopper, a pulverizing mechanism, a discharge hopper, and a motor. The pulverizing mechanism connects the feed hopper and the discharge hopper, and is connected to a transmission gear. The transmission gear is pierced by a rotating shaft, which is connected to the motor via bearings. The motor is mounted on a support plate, and support columns are installed on the support plate and the pulverizing mechanism, each equipped with casters. Utility Model Content

Through the design and installation of the screening component and the storage component, the device is easy for users to operate, produces uniformly pulverized materials, greatly improves pulverizing efficiency, and is more suitable for laboratory sample preparation.

[0004] The technical solution to achieve the above objective is: a laboratory-grade dried plant material pulverizing device, comprising a machine body, a pulverizing chamber, a sieving assembly, and a storage assembly, wherein:

[0006] The upper end of the machine body is provided with a motor support base, and a motor protective shell is provided between the motor support base and the crushing chamber. A crushing motor is installed inside the motor protective shell; a crushing wheel is installed inside the crushing chamber, and the output end of the crushing motor is connected to the crushing wheel.

[0007] The screening assembly includes a screen plate, and a screen plate insertion port is provided on the front side of the machine body. The screen plate passes through the screen plate insertion port and is detachably inserted into the machine body. The screen plate is located below the discharge port.

[0008] The material storage assembly includes a hopper, and a hopper inlet is provided on the front side of the machine body. The hopper passes through the hopper inlet and is detachably inserted into the machine body. The hopper is located below the screen plate.

[0009] The aforementioned laboratory dried plant material pulverizing device includes a sieving assembly that further comprises a sieving motor and a collision kit disposed within the inner cavity of the machine body. The output end of the sieving motor is connected to the collision kit, which is located below the sieve plate. The outer circumferential surface of the collision kit is provided with a plurality of circular protrusions arranged in a ring array.

[0010] In the aforementioned laboratory dried plant material pulverizing device, when the sieve motor drives the collision kit to rotate, the circular protrusion contacts the lower end face of the sieve plate.

[0011] The aforementioned laboratory dried plant material pulverizing device further includes a hopper rolling mechanism in the storage component.

[0014] The beneficial effects of this laboratory dried plant material pulverizing device are:

[0015] (1) This utility model is equipped with a sieving assembly. The sieve plate can screen out the crushed particles, which is convenient for secondary processing of larger particles. In addition, the output end of the sieving motor is connected to a vibration kit. When the vibration kit rotates, the circular protrusion collides with the sieve plate, causing the sieve plate to vibrate. This prevents larger particles from clogging the sieve holes, which would prevent smaller particles from passing through the sieve plate. It can also effectively prevent smaller particles from sticking to the sieve plate and causing waste, making it more suitable for laboratory sample preparation.

[0016] (2) This utility model is equipped with a material storage component. The friction generated by the movement of the hopper inside the machine body will drive the roller to rotate around the central axis, and the sliding will become rolling, which effectively reduces the force required by the worker when disassembling and assembling the hopper.

[0021] Please see Figure 1 , Figure 2 and Figure 3 The preferred embodiment of this utility model is a laboratory dried plant material pulverizing device, which includes a machine body 1, a pulverizing chamber 2, a sieving assembly and a storage assembly.

[0022] The crushing chamber 2 is located above the machine body 1, and a feeding port 3 is provided on one side of the crushing chamber 2. A discharge port 4 is provided at the lower end of the crushing chamber 2, and the lower end of the discharge port 4 is connected to the inner cavity of the machine body 1. A vertically penetrating discharge connection port is provided at the upper end of the machine body 1, and the lower end of the discharge port 4 is connected to the discharge connection port. A baffle 5 is detachably provided at the connection between the crushing chamber 2 and the discharge port 4. Specifically, a baffle insertion slot is provided at the connection between the crushing chamber 2 and the discharge port 4, and the baffle 5 is inserted into the baffle insertion slot.

[0023] The upper end of the machine body 1 is provided with a motor support base 6, and a motor protective shell 71 is provided between the motor support base 6 and the crushing chamber 2. The crushing motor 7 is installed inside the motor protective shell 71. The crushing chamber 2 is provided with a crushing wheel 21. The output end of the crushing motor 7 is connected to the crushing wheel 21. Plant raw materials are added into the crushing chamber 2 from the feeding port 3. The crushing motor 7 drives the crushing wheel 21 to rotate and crush the plant raw materials.

[0024] The screening component is located inside the machine body 1 and below the discharge port 4. The screening component is used to screen the crushed plant materials and retain larger particles. The storage component is located below the screening component and is used to store the plant materials that have passed through the screening component.

[0025] Specifically, the screening assembly includes a screening motor 8, a collision kit 9, and a screen plate 10. A screen plate insertion port is provided on the front side of the machine body 1. The screen plate 10 passes through the screen plate insertion port and is detachably inserted into the machine body 1, located below the discharge port 4. The output end of the screening motor 8 is connected to the collision kit 9, which is located below the screen plate 10. The outer circumferential surface of the collision kit 9 ​​is provided with multiple circular protrusions 91 arranged in a ring array. When the screening motor 8 drives the collision kit 9 ​​to rotate, the circular protrusions 91 contact the lower end face of the screen plate 10, and the collision generates vibration. Smaller particles pass through the screen plate 10, while larger particles that cannot pass through the screen plate 10 remain on it.

[0026] The material storage assembly includes a hopper 11 and a hopper rolling mechanism. A hopper inlet is provided on the front side of the machine body 1. The hopper 11 passes through the hopper inlet and is detachably inserted into the machine body 1, located below the screen plate 10. The hopper rolling mechanism includes two pads 12, which are correspondingly arranged on both sides of the bottom end of the inner cavity of the machine body 1. Each pad 12 has several central shaft mounting holes arranged sequentially from front to back. The central shaft mounting holes on the two pads are correspondingly arranged, and a central shaft 13 is installed in each corresponding set of central shaft mounting holes. Each central shaft 13 is fitted with a roller 14, and the lower end face of the hopper 11 contacts the roller 14. When the hopper 11 is pulled out, the roller 14 rotates around the central shaft 13 under force, reducing the friction generated when the hopper 11 moves within the machine body 1, effectively reducing the force required to assemble and disassemble the hopper 11.

[0027] This utility model discloses a laboratory dried plant material pulverizing device. In use, plant materials are added to the pulverizing chamber 2 through the feeding port 3. The pulverizing motor 7 drives the pulverizing wheel 21 to rotate, pulverizing the plant materials. After removing the baffle 5, the plant materials in the pulverizing chamber 2 fall onto the sieve plate 10 through the discharge port 4. The output end of the sieving motor 8 drives the collision kit 9 ​​to rotate. The circular protrusions on the collision kit 9 ​​collide with the lower end face of the sieve plate 10, generating vibration. Smaller particles pass through the sieve plate 10 and fall into the hopper 11, while larger particles that cannot pass through the sieve plate 10 remain on it. The sieve plate 10 can be removed, and the retained large particles can be poured back into the feeding port 3 for secondary pulverization. The vibration generated by the collision prevents larger particles from clogging the sieve holes and smaller particles from sticking to the sieve plate 10 and causing waste, making it more suitable for laboratory sample preparation. After all the plant materials have been pulverized multiple times, the hopper 11 can be disassembled. The hopper rolling mechanism effectively reduces the force required to disassemble and assemble the hopper 11. This overall design makes the device simple to operate, ensures uniform material pulverization, and greatly improves pulverization efficiency.

[0028] In summary, the laboratory dried plant material pulverizing device of this utility model, through the design and installation of the screening component and the storage component, makes it easy for users to operate, produces uniformly pulverized materials, greatly improves pulverizing efficiency, and is more suitable for laboratory sample preparation.
