Description

Technical Field

[0001] The invention relates to the general field of crushing, grinding or pulverizing technology, and in particular to a feeding device of a cone crusher. Background Art

[0002] Cone crusher is a kind of efficient vibration crushing equipment. The existing cone crusher directly introduces the raw materials into the crushing chamber during crushing. When the raw materials are crushed by the crushing wall, the crushing area is crushed only when the crushing wall is clamped. As a result, the raw materials need to stay in the crushing chamber for a period of time and wait for the crushing area to rotate to the raw material area before they can be crushed, resulting in poor crushing effect. Moreover, when a larger volume of raw materials is poured in, the raw materials will lie horizontally inside the crushing chamber because the volume of the raw materials is larger than the gap at the crushing wall. Therefore, a feeding device for a cone crusher is proposed. Summary of the invention

[0004] Furthermore, a crushing mechanism driven by a feeding plate is provided inside the feeding bin.

[0005] Furthermore, the crushing mechanism includes a plurality of force-bearing shafts connected to the outer wall of the bottom of the upper hopper, each of which is provided with a plurality of rotatable connecting rings, a control rod is provided on the side of the connecting ring close to the conveyor belt, and an L-shaped crushing L-shaped rod is provided on the side of the connecting ring close to the material, which is inclined upward and in an L shape, and the other end of the crushing L-shaped rod is set downward.

[0006] Furthermore, the length of the control rod is greater than the length of one end of the crushing L-shaped rod connected to the connecting ring.

[0007] Furthermore, one end of the crushing L-shaped rod used for crushing is arranged in a conical shape.

[0008] Furthermore, the cloth mechanism includes a support ring, which convexes on one side of the support ring close to the support frame, and a plurality of threaded rods are provided on the end surface of the convex side of the support ring, and a clamping plate is provided on the threaded rod, and the clamping plate is clamped on the support frame through a nut and a threaded rod, and a rotatable cloth bin is provided inside the support ring, and teeth are provided on the top edge of the cloth bin, and an outlet is provided at an eccentric position at the bottom of the cloth bin, a gear is provided in the middle part of the convex side of the support ring, and a rotating motor is provided on the lower surface of the convex side of the support ring, and the output shaft of the rotating motor passes through the convex side of the support ring and is connected to the gear, and the gear is meshed with the teeth of the cloth bin.

[0009] Furthermore, a plurality of balls are provided in a concave shape on the contact surface between the inner wall of the support ring and the outer wall of the material distribution bin.

[0010] Furthermore, a material receiving bin is provided on the support ring, a bottom outlet of the material receiving bin is aligned with the middle of the material distributing bin, and a top of the material receiving bin is arranged in an inverted step structure.

[0011] Furthermore, an insertion ring extending downward and inserted into the interior of the material distribution bin is provided at the bottom outlet edge of the material receiving bin.

[0012] Furthermore, a gear cover covering the top of the gear is provided on one side of the receiving bin close to the gear.

[0013] Beneficial effects: 1. When feeding the cone crusher, pour the raw materials into the upper bin, drive the motor to drive the shaft to rotate through the differential, so that the conveyor belt rotates, and the raw materials are fed from the bottom gap of the upper bin through the feeding plate. Under the thrust of the feeding plate, the raw materials at the bottom gap of the upper bin will move upward with the conveyor belt, and the raw materials will be always sent to the crushing port of the cone crusher through the feeding mechanism on the top of the conveyor belt, thereby improving the crushing efficiency.

[0014] While feeding, the raw materials are stored inside the upper bin and pre-pressed by the crushing mechanism, so that large pieces of raw materials can be pressed into small pieces in advance, so that the raw materials can better pass through the gap at the bottom of the upper bin, and avoid the situation where the raw materials are too large and lie across the crushing area of ​​the cone crusher, resulting in the inability to be crushed.

[0015] By making the length of the control rod greater than the length of one end of the crushing L-shaped rod connected to the connecting ring, the control rod and the crushing L-shaped rod can form a force-saving lever with the force axis as the fulcrum. When the same force acts on the control rod, the crushing L-shaped rod can generate a greater crushing force.

[0016] When distributing the materials, the rotating motor drives the gear to rotate, and the gear meshes with the teeth of the distributing bin to drive the distributing bin to rotate. The raw materials sent by the conveyor belt fall into the inside of the distributing bin, and the distributing bin distributes the raw materials to the crushing area of ​​the cone crusher through the outlet at the bottom. After the raw materials fall into the cone crusher, they can be crushed by the crushing area of ​​the cone crusher, which reduces the residence time of the raw materials in the crushing chamber of the cone crusher and improves the crushing efficiency.

[0017] Compared with the prior art, the present invention has the following advantages: the raw materials can be fed to the crushing area of ​​the cone crusher through the distribution bin, so that the raw materials can be directly crushed after falling into the cone crusher, thereby improving the crushing efficiency; the crushing mechanism can be used to drive the crushing mechanism to pre-crush the raw materials through the thrust of the feeding plate when the conveyor belt is rotating, so that the raw materials with too large volume can be pressed down, and the situation that the raw materials are too large and cause them to lie horizontally inside the crushing chamber of the cone crusher can be avoided.

Under the thrust of the loading plate 141, the raw materials located at the bottom gap of the loading bin 107 will move upward with the conveyor belt 104, and the raw materials will always be sent to the crushing port of the cone crusher through the feeding mechanism 2 at the top of the conveyor belt 104, thereby improving the crushing efficiency.

[0031] For further reference, Figure 2 and Figure 4 , a crushing mechanism 108 driven by a loading plate 141 is provided inside the loading bin 107; In the specific implementation, while feeding, the raw materials are stored in the upper bin 107, and the raw materials are pre-pressed by the crushing mechanism 108, so that large pieces of raw materials are pressed into small pieces in advance, so that the raw materials can better pass through the gap at the bottom of the upper bin 107, and it can avoid the situation where the raw materials are too large and lie across the crushing area of ​​the cone crusher, resulting in the inability to be crushed.

[0032] For further reference, Figure 4 The crushing mechanism 108 includes a plurality of force-bearing shafts 181 connected to the outer wall of the bottom of the upper bin 107, each of which is provided with a plurality of rotatable connecting rings 182, a control rod 183 is provided on the side of the connecting ring 182 close to the conveyor belt 104, and a crushing L-shaped rod 184 is provided on the side of the connecting ring 182 close to the material, which is inclined upward and in an L shape, and the other end of the crushing L-shaped rod 184 is arranged downward; In the specific implementation, when pre-pressing is performed, the conveyor belt 104 rotates, so that the loading plate 141 rotates with the conveyor belt 104, so that the loading plate 141 will push the tail of the control rod 183 upwards, and the crushing L-shaped rod 184 will rotate and press down with the force-bearing axis 181 as the fulcrum and the connecting ring 182 as the center, so that the downward end of the crushing L-shaped rod 184 presses the raw material downward, and the raw material breaks when the pressure drops, and the raw material is squeezed and crushed by the crushing L-shaped rod 184.
