Description

Technical Field

[0001] This utility model relates to the field of cone crushers, and in particular to an anti-material accumulation structure for cone crushers. Background Technology

[0002] A cone crusher is a type of crushing machinery suitable for raw materials in the metallurgical, construction, road building, chemical, and silicate industries. Depending on the crushing principle and the desired particle size, it is available in many models. Crushers are widely used in mining, metallurgy, building materials, highways, railways, water conservancy, and chemical industries. Cone crushers feature a large crushing ratio, high efficiency, low energy consumption, and uniform product particle size, making them suitable for medium and fine crushing of various ores and rocks.

[0003] In the operation of existing cone crushers, the discharge hopper continuously discharges raw materials from the feed inlet into the crusher. Due to the different sizes of stones to be crushed and the excessively fast feeding speed, the feed inlet of the cone crusher becomes clogged, requiring manual cleaning before it can continue to be used. Utility Model Content

[0004] In order to solve the problems in the background art, this utility model adopts the following technical solution:

[0005] An anti-material accumulation structure for a cone crusher includes a cone crusher body. A material distribution seat is fixedly installed at the upper feed inlet of the cone crusher body via a bracket. A feed cylinder communicating with the inner cavity is fixedly connected to the upper end of the material distribution seat. A crushing mechanism is fixedly installed on the inner wall of the feed cylinder. A frustum is fixedly connected to the center of the upper end of the material distribution seat. A discharge channel is evenly arranged around the periphery of the frustum on the upper end of the material distribution seat. A turntable is provided at the bottom of the material distribution seat. Multiple sets of discharge ports corresponding to the discharge channels are arranged through the upper end of the turntable. A motor that drives the turntable to rotate is fixedly installed inside the frustum.

[0006] Preferably, the crushing mechanism includes an electric push rod symmetrically and fixedly connected to the outside of the feed cylinder, the power end of the electric push rod extending movably through the feed cylinder into its inner cavity, and an extrusion plate fixedly connected to the inner end of the electric push rod.

[0007] Preferably, the mating surfaces of the extrusion plates and the mating surfaces between the extrusion plates and the inner wall of the feed cylinder are uniformly provided with crushing teeth.

[0008] Preferably, the motor is fixedly installed inside the truncated cone, and a rotating rod is fixedly connected to the power end of the motor. The rotating rod moves through the material distribution seat and is then fixedly connected to the center position of the upper end of the turntable.

[0009] Preferably, the truncated cone is fixedly connected to the upper end of the material distribution seat by bolts, and the bottom edge of the truncated cone is aligned with the upper end of the material discharge channel.

[0010] Preferably, the front of the material distribution seat is provided with a switch group, which includes an electric push rod and a motor switch.

[0011] Compared with the prior art, the present invention has the following beneficial effects;

[0012] This invention features a feed cylinder installed at the top of the existing cone crusher body. Inside the feed cylinder, a reciprocating crushing mechanism pre-crushes large raw materials, reducing their size for easier subsequent crushing and preventing blockages. A distribution seat at the bottom of the feed cylinder disperses the feed material to different discharge channels, preventing material accumulation and blockages caused by feeding from the same location. Furthermore, the discharge channels can be selectively opened and closed intermittently based on the crushing conditions, further preventing blockages. These three methods effectively prevent material accumulation and blockages during the cone crusher's crushing process. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 An anti-material accumulation structure for a cone crusher includes a cone crusher body 1. A material distribution seat 2 is fixedly installed at the upper feed inlet of the cone crusher body 1 via a bracket. A feed cylinder 3 communicating with the inner cavity is fixedly connected to the upper end of the material distribution seat 2. The characteristic is that a crushing mechanism 4 is fixedly installed on the inner wall of the feed cylinder 3. A frustum 5 is fixedly connected to the center of the upper end of the material distribution seat 2. A discharge channel 6 is evenly arranged around the frustum 5 at the upper end of the material distribution seat 2. The frustum 5 is fixedly connected to the upper end of the material distribution seat 2 by bolts, and the bottom edge of the frustum 5 is aligned with the upper end of the discharge channel 6. A turntable 7 is provided at the bottom of the material distribution seat 2. Multiple sets of discharge ports 8 corresponding to the discharge channels 6 are arranged through the upper end of the turntable 7. A motor 9 for driving the turntable 7 to rotate is fixedly installed inside the frustum 5.

[0024] The crushing mechanism 4 includes an electric push rod 401 symmetrically fixedly connected to the outside of the feed cylinder 3. The power end of the electric push rod 401 extends through the feed cylinder 3 into its inner cavity. An extrusion plate 402 is fixedly connected to the inner end of the electric push rod 401. Crushing teeth 403 are evenly arranged on the mating surface of the extrusion plate 402 and the mating surface between the extrusion plate 402 and the inner wall of the feed cylinder 3.

[0025] The motor 9 is fixedly installed inside the truncated cone 5. The power end of the motor 9 is fixedly connected to a rotating rod 901, and the rotating rod 901 moves through the material distribution seat 2 and is fixedly connected to the center position of the upper end of the turntable 7.

[0026] The material distribution seat 2 has a switch group 201 on its front side, which includes an electric push rod 401 and a switch for the motor 9, making it convenient for staff to control the above-mentioned electrical components.

[0027] Based on the above structural configuration, when using this device, the operator pours the crushed raw material into the feed cylinder 3 and simultaneously uses the switch group 201 to start the electric push rod 401, which reciprocates and extends. When the raw material passes through the feed cylinder 3, part of it falls between the opposing extrusion plates 402, and part falls between the extrusion plates 402 and the inner wall of the feed cylinder 3. After passing through the crushing teeth 403 on the opposing surfaces, the raw material is crushed and compressed, reducing the volume of material entering the cone crusher and preventing accumulation and blockage. The raw material after preliminary crushing slides down the inclined surface of the truncated cone 5 to different discharge channels 6 for diversion. The different discharge channels 6 are connected to different positions of the upper feed port of the cone crusher body 1, so that material is not discharged in one place and causes blockage. At the same time, considering that sometimes the discharge speed is too fast, which may cause too much raw material to accumulate at the upper end of the cone crusher body 1, the motor 9 can be started by the switch in the switch group 201 at an appropriate speed. The motor 9 drives the bottom turntable 7 to rotate. The discharge port 8 at the bottom of the turntable 7 intermittently opens and closes the discharge channel 6, thereby controlling the discharge speed and effectively avoiding the accumulation and blockage of raw material caused by excessive discharge.

[0028] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.

[0029] In the description of this utility model, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
