Description

Composite cutter head and pulverizer

Technical Field

The utility model belongs to the technical field of the comminuted, a blade disc is related to, especially relate to a compound blade disc and rubbing crusher.

Background

The hammer mill is the most widely used one at present, has high electric product quantity and good universality, and is structurally composed of a feeding mechanism, a milling chamber (a rotor, a hammer, a sieve sheet and a toothed plate) and a discharging part (a fan, a collecting barrel and a dust collecting cloth bag).

Hammer mill during operation, fodder gets into from feeding mechanism and smashes the room, flies to the pinion rack under the strike of the hammer leaf of high-speed gyration, receives the strike of hammer leaf again after colliding with the pinion rack and rebounding, shines simultaneously between face and hammer leaf, and the fodder receives strong friction again, and under repeated strike collision and friction, the fodder is smashed gradually, makes the thing of smashing pass through the sieve mesh by the air current in crushing room and discharges.

The hammer mill mainly relies on the impact action of the hammer on the feed raw materials to crush the materials. The higher the linear velocity of the hammer, the greater the impact force of the hammer on the feed particles, and the stronger the crushing capability. Therefore, within a certain range, the crushing capacity of the crusher can be improved by increasing the linear velocity of the hammer. However, increasing the linear velocity of the hammer increases the diameter of the rotor of the crusher, and accordingly, the size of the crusher increases, which causes inconvenience, and the conventional hammer has limited crushing force of the hammer during operation, resulting in low crushing efficiency.

The material cutter is a shearing device and has the working principle that a cutter repeatedly cuts materials under the driving of a power device to thin the materials.

The existing stock cutter is used for cutting a large material into pieces or small blocky materials, the hammer grinder is used for grinding the small materials into powdery small materials, the two types of equipment are mutually independent, when the large material is crushed, the material is often cut by the stock cutter firstly and then crushed by the crusher, the final crushing of the material can be completed on the two types of equipment, and the production efficiency is reduced.

CN 201644148U discloses a hammer type novel crusher, which comprises a feeding port, a mesh screen, a rotor, a base, a driving motor, a casing, a power conversion device and a discharging port, and is also provided with a reverse rotation type rat cage frame, a reverse rotation hammer sheet, a forward rotation hammer sheet and a reverse rotation bracket; the tangent line of the joint of the forward rotary hammer sheet and the rotor forms an included angle of 60 degrees, the tangent line of the joint of the reverse rotary hammer sheet and the reverse rotary squirrel cage frame forms an included angle of 60 degrees, the power conversion device is respectively fixedly connected with the rotor and the reverse rotary bracket, and the power conversion device is internally provided with a power speed change device and a power reversing device. Wherein the hammer leaf is fixed to be set up, long-time use easily makes the life-span of hammer leaf reduce, and this rubbing crusher structure is complicated, and the maintenance degree of difficulty is high.

CN 205731519U discloses a hammer mill, in which a rotary table is provided in the mill body, and the rotary table is provided with a notch, and the edge of the notch is provided with a blade, when the rotary shaft rotates, the rotary table rotates synchronously, so that the blade cuts off the object passing through the notch from the outlet, but the notch structure makes the efficiency of cutting the material of the mill lower, and the main material crushing structure is still the hammer.

CN 206454757U discloses a novel section rubbing crusher, this rubbing crusher's blade disc and hammer leaf locate the bucket through the pivot in, be equipped with the blade on the blade disc, still be equipped with the cutter group that is located between blade disc and the hammer leaf in the pivot, cutter group includes the cutter more than three groups, the bold material is further smashed by cutter group after the blade disc is cut into slices, smash the material by the hammer leaf again at last, the time of having reduced the crushing material of hammer leaf, but this rubbing crusher is in the same place blade, cutter and hammer leaf simply, make the volume of section rubbing crusher too big. Similarly, the multifunctional hay cutting, kneading and crushing machine disclosed in CN 2614433Y also combines the feeding mechanism, the cutter head and the hammer mechanism simply, so that the structure of the crushing machine is complicated and the size is large.

Therefore, a new cutter head is designed, the cutter head can cut off materials and can crush the materials, and therefore the crusher is compact in structure and simple to disassemble, and the space utilization rate is improved. In addition, the new cutter head has the cutting and crushing functions, so that power consumption parts are reduced, and the electric product quantity of the crusher is increased.
