Description

Technical Field

[0001] This utility model relates to the field of crusher technology, and in particular to a cassava crusher. Background Technology

[0002] Currently, most cassava crushers in China have a simple structure, consisting of a rotor assembly, a base, bearings, bearing housings, pulleys, belts, and a motor. Material enters the crushing chamber through the feed inlet, where it is crushed by the high-speed rotating blades. The crushed material is then discharged from the discharge outlet at the bottom.

[0003] Because this cassava crusher relies solely on the rotor assembly to crush materials, and discharges the materials directly after a single hammering, the fineness of the crushing process is often not guaranteed.

[0004] Therefore, it is necessary to design a cassava crusher to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cassava crusher.

[0006] The technical solution of this utility model is: a cassava crusher, including a base and a crushing chamber disposed on the base; a rotor assembly is rotatably installed in the crushing chamber; a shearing component that cooperates with the rotor assembly for crushing is detachably connected to the side wall of the crushing chamber; a crushing fineness control device is provided at the bottom of the crushing chamber in an adjustable vertical position; the rotor assembly includes a main shaft and hammers evenly distributed along the main shaft along the axial direction, and adjacent hammers are staggered.

[0007] The two ends of the main shaft are rotatably connected to the crushing chamber via bearings and bearing seats; the base is equipped with a drive mechanism for driving the main shaft.

[0008] The drive mechanism includes a drive motor; a pulley is fixed to the end of the main shaft; the drive motor is connected to the pulley via a belt.

[0009] The output shaft of the drive motor and the outer side of the pulley are also provided with protective covers.

[0010] The shearing assembly includes a mounting plate and shearing plates evenly distributed on the mounting plate, with a gap formed between adjacent shearing plates to cooperate with the hammer blade.

[0011] The fineness control device for crushing includes two symmetrically arranged fixed plates and several baffles distributed in an arc between the two fixed plates; the two fixed plates are respectively fixed to the two side walls of the crushing chamber by bolts, and the crushing chamber is provided with elongated holes in the vertical direction at the bolt locations.

[0012] A spacer is fitted on the main shaft between two adjacent hammer blades.

[0013] The two adjacent hammer blades are set vertically together.

[0014] The hammer blade has cemented carbide at both ends.

[0015] By adopting the above technical solution, this utility model has the following beneficial effects: A shearing assembly that works with the rotor assembly for crushing is detachably connected to the side wall of the crushing chamber. Simultaneously, the staggered arrangement of the hammers on the rotor assembly increases the number of impacts of the material within the crushing chamber, improving the crushing effect. Furthermore, the shearing assembly is easy to disassemble and replace, making maintenance more convenient. Additionally, a fineness control device is installed at the bottom of the crushing chamber, allowing larger materials to remain within the crushing chamber for further impact, preventing them from being directly discharged. Moreover, the gap between the fineness control device and the hammers can be adjusted by regulating the height of the fineness control device, thereby controlling the fineness of the crushing.

Detailed Implementation

[0026] (Example 1)

[0027] See Figures 1 to 7 This embodiment of a cassava crusher includes a base 1 and a crushing chamber 2 disposed on the base 1; a rotor assembly 3 is rotatably mounted in the crushing chamber 2; a shearing component 4 that cooperates with the rotor assembly 3 for crushing is detachably connected to the side wall of the crushing chamber 2; a crushing fineness control device 5 is provided at the bottom of the crushing chamber 2 with adjustable vertical position; the rotor assembly 3 includes a main shaft 3-1 and hammers 3-2 evenly distributed along the main shaft 3-1, and adjacent hammers 3-2 are staggered.

[0028] Furthermore, in order to facilitate the installation of the main shaft 3-1 and ensure the stability of the movement of the main shaft 3-1, both ends of the main shaft 3-1 are rotatably connected to the crushing chamber 2 through bearings 3-3 and bearing seats 3-4; the base 1 is provided with a drive mechanism 6 for driving the main shaft 3-1 to operate.

[0029] Furthermore, in order to facilitate better driving of the spindle 3-1, the drive mechanism 6 includes a drive motor 6-1; a pulley 6-2 is fixed at the end of the spindle 3-1; the drive motor 6-1 is connected to the pulley 6-2 via a belt 6-3.

[0030] Furthermore, a protective cover 6-4 is provided on the outer side of the output shaft of the drive motor 6-1 and the pulley 6-2 to provide protection.

[0031] Furthermore, in order to facilitate the replacement and installation of the shearing assembly 4, the shearing assembly 4 includes a mounting plate 4-1 and shearing plates 4-2 evenly distributed on the mounting plate 4-1, and a gap is formed between two adjacent shearing plates 4-2 to cooperate with the hammer blade 3-2.

[0032] Furthermore, in order to facilitate better adjustment of the position of the crushing fineness control device 5, the crushing fineness control device 5 includes two symmetrically arranged fixing plates 5-1 and several stop rods 5-2 distributed in an arc between the two fixing plates; the two fixing plates 5-1 are respectively fixed to the two side walls of the crushing chamber 2 by bolts, and the crushing chamber 2 is provided with elongated holes in the vertical direction at the bolt locations.

[0033] Furthermore, in order to ensure that the gap between two adjacent hammer blades 3-2 is consistent, a spacer sleeve 3-5 is fitted on the main shaft 3-1 between two adjacent hammer blades 3-2.

[0034] Preferably, the two adjacent hammer blades 3-2 are arranged vertically, which can further increase the number of times the hammer blades 3-2 strike the material.

[0035] Furthermore, the two ends of the hammer blade 3-2 are designed to be vacuum sintered from high-quality cemented carbide 3-6, which greatly extends the service life of the hammer blade 3-2, reduces the replacement frequency of the hammer blade 3-2, and improves production efficiency.

[0036] In this embodiment of the cassava crusher, when the material enters the crushing chamber 2, it is crushed by the high-speed impact of the hammer blades 3-2. When passing through the shear plates 4-2 on both sides, the material collides with the surface of the shear plates 4-2 multiple times, causing the material flow direction to change abruptly multiple times, increasing the number of impacts on the material. The crushing fineness control device 5 at the bottom effectively prevents larger materials from being discharged directly, allowing larger materials to continue to be crushed in the crushing chamber. The qualified crushed material is discharged from the discharge port through the gap of the fineness control device.

[0037] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
