Description

Technical Field

[0001] This utility model relates to the field of pulverizers, and more specifically, to a pulverizing chamber suspension structure for an ultrafine pulverizer. Background Technology

[0002] A crusher is a machine that crushes large solid raw materials to the required size. A crusher consists of coarse crushing, fine crushing, and pneumatic conveying devices, achieving its crushing purpose through high-speed impact. It utilizes wind power to grind materials in a single pass, eliminating the need for traditional screening processes. It is mainly used in mining, building materials, and other industries.

[0003] For example, CN108787028B discloses a small ultrafine pulverizer with a self-cleaning mechanism, including a pulverizing device. The pulverizing device includes a pulverizing chamber, pulverizing blades, and a pulverizing motor. The pulverizing chamber is connected to a collection box and a feeding channel. The feeding channel passes through the collection box and communicates with the pulverizing chamber. A transition channel is provided between the feeding channel and the collection box near the pulverizing chamber. A rotating disk is rotatably mounted on the side of the collection box away from the pulverizing chamber, and a cleaning brush is mounted on the rotating disk. The collection box is also connected to a discharge channel, and a cleaning spring is mounted inside the discharge channel. The cleaning spring slides and / or rotates within the discharge channel. The rotating disk drives the cleaning brush to rotate and clean the inside of the collection box. The user cleans the medicinal powder adhering to the discharge channel using the cleaning spring. By improving the convenience of cleaning the small ultrafine pulverizer, the user can quickly clean the residual medicinal powder inside the small ultrafine pulverizer, thus improving the efficiency of medicinal material preparation.

[0004] As can be seen from the above-mentioned publicly available solutions, the current suspension crushing mechanism of the crusher is set in a fixed position, which can only crush materials in one position. This reduces the effect and efficiency of crushing materials in other positions. Moreover, when materials are put into the machine box, the materials fall directly and are prone to colliding with the crushing mechanism inside the machine box. Furthermore, the repeated falling of materials into one position at the bottom of the machine box over a long period of time can easily cause impact damage to that position, affecting the service life and performance of the machine box. Utility Model Content

[0005] The purpose of this utility model is to provide a suspension structure for the pulverizing chamber of an ultrafine pulverizer, so as to solve the problems of adjusting the suspension pulverizing mechanism and protecting the machine casing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a suspension structure for the pulverizing chamber of an ultrafine pulverizer, comprising a chassis and a rotating block. A cover is bolted to the upper end of the chassis. A motor is fixedly mounted on the upper end of the cover. A retaining cover is fixedly mounted on the motor shaft of the motor. A telescopic rod is fixedly mounted inside the retaining cover. A corrugated cylinder is fixedly mounted on the lower end of the retaining cover. A reinforcing block is fixedly mounted on the lower end of the telescopic rod. A rotating shaft is fixedly mounted on the lower end of the reinforcing block. Multiple pulverizing blades are fixedly mounted on the rotating shaft. Feed hoppers are fixedly mounted on the left and right sides of the upper end of the cover. Buffer rods are fixedly mounted on the left and right sides of the lower end of the cover. Multiple protrusions are fixedly mounted on the lower end of the buffer rods. A spring is slidably sleeved at the lower end of the buffer rod, and a buffer plate is also slidably sleeved at the lower end of the buffer rod. A telescopic rod is installed through a retainer, and the telescopic rod is connected to a rotating shaft. This allows the rotating shaft to move automatically up and down by extending and retracting the telescopic rod, thereby driving the crushing blade to move automatically up and down. This facilitates the crushing of materials at different positions through the movement of the crushing blade, increasing the crushing effect and efficiency. At the same time, a buffer plate is installed at the lower end of the feed hopper, and the buffer rod connects the spring and the buffer plate, so that the buffer plate has a buffering function, catching the material discharged from the feed hopper and allowing the material to slide down the inner wall of the casing to the lower end of the casing. This reduces the impact damage to the casing caused by the falling material and avoids the material hitting the crushing structure and damaging the crushing mechanism.

[0007] Preferably, the motor is located at the top of the chassis, and the motor shaft is rotatably located inside the chassis cover. The chassis cover allows for easy removal and opening of the chassis, facilitating cleaning and maintenance of the interior.

[0008] Preferably, the cover is rotatably mounted at the lower end of the cover and at the upper end of the inner part of the chassis. The corrugated cylinder protects the telescopic rod, and the annular groove and the rotating block limit the cover, thereby increasing the stability of the cover installation and reducing vibration.

[0009] Preferably, the telescopic rod is disposed inside the corrugated cylinder, the retaining cover is provided with an annular groove, and rotating blocks are respectively rotatably disposed on the left and right sides inside the annular groove. The connection between the lower end of the telescopic rod and the rotating shaft is reinforced by the setting of the reinforcing blocks.

[0010] Preferably, the rotating block is fixedly provided with a lifting block, the upper end of which is fixedly provided at the lower end of the box cover. The two feeding hoppers facilitate the dispersed feeding of materials, increasing convenience and protection.

[0011] Preferably, the lower end of the corrugated cylinder is fixedly disposed on the upper end of the reinforcing block, the rotating shaft is rotatably disposed inside the machine housing, and the crushing blade is rotatably disposed inside the machine housing.

[0012] Preferably, a discharge port is fixedly provided at the lower end of the chassis, a buffer plate is provided at the lower end of the feed hopper, the upper end of the spring is fixedly provided on the lower surface of the buffer plate, and the lower end of the spring is fixedly provided on the upper surface of the protrusion.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model uses a cover to set a telescopic rod, which is connected to a rotating shaft. This allows the rotating shaft to move up and down automatically by extending and retracting the telescopic rod, thereby driving the crushing blade to move up and down automatically. This makes it easier to crush materials at different positions by moving the crushing blade up and down, thus increasing the crushing effect and efficiency.

[0015] (2) This utility model provides a buffer plate at the lower end of the feed hopper, and the buffer rod connects the spring and the buffer plate so that the buffer plate forms a buffer function, catches the material discharged into the feed hopper, and then allows the material to slide down the inner wall of the machine box to the lower end of the machine box, thereby reducing the impact damage to the machine box when the material falls, and avoiding the material from hitting the crushing structure and causing damage to the crushing mechanism.
