[0046] The following preferred embodiment is combined with the drawings to more clearly and completely illustrate the present application.

[0047] The present embodiment provides a desktop cone type crushing and granulating equipment, as shown in Figure 1 and Figure 2 , the desktop cone type crushing and granulating equipment comprises:

[0048] Crushing part 1, the crushing part 1 comprises a feeding hopper 11, the volume of the feeding hopper 11 is 2-3L;

[0049] The driving part 2 comprises a shell 21 and a driving motor 22 arranged in the shell 21, the driving motor 22 is in a cylindrical structure, the diameter of the driving motor 22 is not greater than 135 mm, and the height of the driving motor 22 is not higher than 235 mm;

[0050] The transmission part 3 is arranged between the crushing part 1 and the driving part 2, and is used for transmitting the power of the driving part 2 and driving the crushing part 1 to operate.

[0051] Specifically, the driving part 2 comprises a shell 21 and a driving motor 22 arranged in the shell 21, the shell 21 is in a rectangular structure, the driving motor 22 is in a cylindrical structure, and the volume of the driving motor 22 is calculated by the volume calculation formula V = πR 2 h, wherein the value range of R is not greater than 135 mm, the value range of h is not greater than 235 mm, and π is 3.14. It can be understood that by limiting the volume of the driving motor 22, the volume of the shell 21 for covering the driving motor 22 is correspondingly reduced. Compared with the traditional large-volume motor that cannot be arranged on the desktop, the shell 21 can be installed on the desktop, and thus is suitable for the limited space in the laboratory.

[0052] The embodiment also comprises the crushing part 1 and the transmission part 3, the transmission part 3 is arranged between the crushing part 1 and the driving part 2, one end of the transmission part 3 is connected with the shell 21, the other end of the transmission part 3 is connected with the crushing part 1, and the power of the driving motor 22 is transmitted to the crushing part 1 through the transmission part 3. At the same time, the transmission part 3 can also support the crushing part 1, so that the crushing part 1 can be arranged in a cantilever structure, thereby not occupying the desktop space, so as to further reduce the space required when the desktop cone type crushing and granulating equipment is used. The crushing part 1 comprises a feeding hopper 11, the volume of the feeding hopper 11 is only 2-3 L compared with the traditional feeding cavity. By limiting the volume of the feeding hopper 11 and cooperating with the volume-limited driving motor 22, that is, by reducing the volume of each component of the desktop cone type crushing and granulating equipment, the volume of the crushing and granulating equipment is reduced as a whole, so that the crushing and granulating equipment can be installed on the desktop and is convenient to use in the limited space in the laboratory.

[0053] It can be understood that by limiting the volume of the feeding hopper 11, the feeding hopper 11 can only accommodate materials in the order of 10 grams each time, which occupies less space and is suitable for small-batch groping granulation in the laboratory compared with the traditional large-volume crushing and granulating equipment which can accommodate materials in the order of 1000 grams. It meets the crushing demand of a small amount and a trace amount of solid preparation, reduces the waste of materials, and reduces the noise generated by the driving motor 22 when stirring the materials.

[0054] Further, in the embodiment, the crushing part 1 further comprises a crushing hopper 12, and the volume of the crushing hopper 12 is 0.3-0.5L.

[0055] Specifically, the crushing hopper 12 is used as a working area for crushing solid preparations, and the volume of the crushing hopper 12 is smaller than that of the crushing cavity in the prior art, so that the crushing hopper 12 can only crush a small amount of solid preparations, for example, 10 grams of solid preparations, in each processing process, thereby meeting the needs of small-scale equipment in the laboratory. At the same time, by limiting the size of the crushing hopper 12 used for crushing solid preparations, the volume of the crushing and granulating equipment can be further reduced, so that the crushing and granulating equipment can be placed on a desktop for use, thereby meeting the needs of small-scale equipment.

[0056] As shown in Figure 5 the embodiment, the crushing part 1 further comprises a gear box 13, and the gear box 13 is arranged away from the feeding hopper 11. The crushing hopper 12 is located between the feeding hopper 11 and the gear box 13, and the feeding hopper 11, the crushing hopper 12 and the gear box 13 are sequentially communicated along the feeding direction. The feeding hopper 11 further comprises a protective screen 111, and the protective screen 111 is provided with a feeding port 1111 along the feeding direction.

[0057] Specifically, the feeding hopper 11, the crushing hopper 12 and the gear box 13 are sequentially arranged along the feeding direction and are in communication with each other. The feeding hopper 11 is located above the crushing hopper 12 and the gear box 13 and is used to accommodate solid preparations. The crushing hopper 12 is located between the feeding hopper 11 and the gear box 13 and is used to crush a small amount of solid preparations. The gear box 13 is used to drive the crushing hopper 12 to operate, thereby realizing the processing of solid preparations. It can be understood that the volumes of the feeding hopper 11 and the crushing hopper 12 are limited, and accordingly, the volume of the gear box 13 can be reduced, so that the volume of the crushing part 1 is reduced, thereby meeting the needs of installation on a desktop in a laboratory under effective space.

[0058] As shown in Figure 3 and Figure 4 the embodiment, the solid preparations that are not suitable for experimental requirements after being crushed by the crushing hopper 12 can flow out through the discharge port at the connection between the crushing hopper 12 and the gear box 13, pass through the outer surface of the gear box 13, and finally be discharged from the end of the gear box 13 away from the crushing hopper 12. An operator can set a collecting device, such as a collecting bag or a collecting vessel in the prior art, at the end of the gear box 13 away from the crushing hopper 12, and details are not described herein.

[0060] In other embodiments, the protective screen 111 can also be in a rectangular structure, and the opening size of the feeding port 1111 is smaller than the size of the hands of the operator, so that the protective purpose can be achieved, which is the prior art and will not be described in detail here.

[0061] In the embodiment, the crushing hopper 12 is a conical cavity, and the feeding hopper 11 has a flow guide surface.

[0062] Specifically, the crushing hopper 12 is a conical cavity, compared with other shapes of cavities, such as a rectangular structure cavity or a spherical structure cavity, the volume is smaller under the same size, and the corresponding space of the desktop is smaller, at the same time, the conical cavity can reduce the residue of the material on the cavity wall, thereby reducing the waste of the material.

[0063] In addition, the feeding hopper 11 also has a flow guide surface, which can guide the flow of the material, so that the material can quickly flow to the crushing hopper 12 below the feeding hopper 11, reduce the residue of the material in the feeding hopper 11, and reduce the working hours of the crushing material, thereby improving the processing efficiency. And the conical cavity of the crushing hopper 12 can also facilitate the uniform distribution of the material in the crushing hopper 12, thereby improving the uniformity and consistency of the crushing material.

[0064] In the embodiment, the flow guide surface is the inclined side wall of the feeding hopper 11, the flow guide surface is inclined from the feeding direction to the axis of the feeding hopper 11, and the inclination angle is 50-60°.

[0065] Specifically, the feeding hopper 11 is also a conical cavity, and the conical cavity includes an inclined side wall, i.e. a flow guide surface, and the inclination angle of the flow guide surface is 50-60°. Compared with other inclination angles, the above inclination angle can ensure that the material residue in the feeding hopper 11 is less.

[0066] In the embodiment, the crushing hopper 12 is provided with a screen (not shown in the figure), the screen has a rotatable rotor (not shown in the figure), the material is extruded from the screen by the rotor and located on the surface of the screen away from the rotor, the gear box 13 has an output shaft (not shown in the figure), the output shaft extends into the crushing hopper 12, the rotor is sleeved on the output shaft, and the rotor is driven and rotated by the output shaft.

The output shaft is inserted into the crushing hopper 12 to drive the rotor to rotate and extrude the material from the screen, thereby meeting the crushing requirements of the laboratory for the material.

[0068] In the embodiment, the transmission part 3 comprises a connecting arm 31, one end of the connecting arm 31 is connected with the shell 21, the other end of the connecting arm 31 is connected with the gear box 13, and the transmission part (not shown in the figure) is arranged in the connecting arm 31.

[0069] Specifically, the connecting arm 31 is a cylindrical rod and has a space for accommodating the transmission part inside. In this embodiment, the transmission part is taken as a transmission belt for illustration, but it is not limited thereto. First, the driving motor 22 is arranged in the shell 21 along the feeding direction, the driving shaft of the driving motor 22 extends to the connecting part of the connecting arm 31 and the shell 21, and correspondingly, one end of the output shaft of the gear box 13 extends to the connecting part of the gear box 13 and the shell 21. The transmission belt is arranged in the connecting arm 31 and extends into the gear box 13 and the shell 21 at both ends, and the transmission belt is sleeved on the driving shaft and the output shaft at both ends, so that the transmission belt is driven to rotate when the driving motor 22 rotates, and the power is transmitted to the output shaft to drive the rotor coaxially arranged with the output shaft.

[0070] Of course, in other embodiments, the transmission part can also be a transmission shaft in the prior art, and gears are arranged on the driving shaft, the output shaft and the transmission shaft, and the gears are meshed with each other to transmit power.
