Abstract

The utility model relates to a high-speed grinder which is a material grinding machine. A plurality of springs are adopted to replace the crank rockers in the prior art. One end of each spring is connected with a tray, and the other end of each spring is connected with a machine frame, so the service life of a grinding container, a bearing and even the whole high-speed grinder is prolonged in a great degree. In addition, the noise, the vibration and the electric power consumption of the equipment are reduced. The high-speed grinder can be widely used for grinding the material in the industries, such as silicates, medicine and chemical industry. The grinding time can be reduced, as 20-40 minutes is enough.

Description

High-speed grinder

The utility model is about grinding material machinery.

In prior art, because rotatablely moving of the grinding container of high-speed grinder is to realize by crank rocker, owing to 400～500 rev/mins of its turn ups, the rocking bar per minute also will act on the reciprocally swinging of same number of times again.Therefore, the bearing of rocking bar and connecting rod joint is subjected to high-frequency axial load and radial load simultaneously, and makes bearing running hot, even damages, and influences its service life; Simultaneously, crank rocker has an angle of oscillation in motion process, on dead point of swing, can produce the impulsive force of moment, makes grinding container very easily damage, reduce the service life of crank rocker and body, and the vibration of high-speed grinder, noise are increased.

The purpose of this utility model provides a kind of high-speed grinder that does not need crank rocker, is used for the grinding of industry materials such as silicate, medicine, chemical industry.Wet grinding can be used for, dry grinding can be used for again.

Principle of the present utility model is that the other end is separately fixed at the diagonal place of frame at the spring of hanging on the pallet of grinding container more than four or four.When grinding container rotated around central shaft, pallet was subjected to pining down of spring, from, and produce around the motion of central axes rotation.

The utility model has the advantages that only need to take down crank rocker on the basis of existing equipment, the spring of hanging more than four or four gets final product, so structure is simpler, cost is lower between pallet and frame diagonal; Simultaneously, because spring is a flexible material, produces impulsive force in rotary course hardly, running steadily, equipment noise and vibration are all littler, can also prolong the service life of grinding container greatly, after device start ran well, spring had the energy storage effect, in the normal operation process, this stretches spring that and contracts, and potential energy is kept substantially constant, and is few to the loss of energy.

Accompanying drawing is the structural representation of this high-speed grinder that provides of the utility model.Wherein accompanying drawing 1 is the facade structures schematic diagram of high-speed grinder, and accompanying drawing 2 is planar structure schematic diagrames of high-speed grinder.

In the accompanying drawings, spring (1), grinding container (2), motor (3), small belt pulley (4), V-belt (5), pallet (6), bearing (7), eccentric shaft (8), bottom nut (9), central shaft (10), bearing (11), body (12), big belt pulley (13).Spring (1) one end hangs over the last other end of pallet (6) and hangs on the frame (14), and pallet (6) rotates around eccentric shaft (8) by bearing (7); Grinding container (2) is used for splendid attire grinding charge material, links to each other with an end of eccentric shaft (8), and is connected with big belt pulley (13) by the other end of eccentric shaft (8); Motor (3) is by small belt pulley (4), V-belt (5), big belt pulley (13), for rotatablely moving of grinding container (2) provides power; Bottom nut (9) is used for fixing central shaft (10); Central shaft (10) links to each other with big belt pulley (13), and when big belt pulley (13) rotated, grinding container (2) also rotated around central shaft.

Introduce embodiment of the present utility model below: material to be ground is put into grinding container (2), actuating motor (3), small belt pulley (4) rotates immediately, and by V-belt (5) drive big belt pulley (13) rotation, and then drive eccentric shaft (8), pallet (6), grinding container (2) and rotate, grind through certain hour, when the grinding charge material reaches desired fineness requirement, can cut off the power supply of motor (3), after container to be ground (2) stops operating fully, can take out the grinding charge material.

This high-speed grinder that the utility model provides both can be made into the single head machine that has only a grinding container, can be made into the bull machine of two or two above grinding containers again, can further improve grinding efficiency.

Claims

1, a kind of high-speed grinder, form by grinding container (2), motor (3), small belt pulley (4), V-belt (5), pallet (6), bearing (7), eccentric shaft (8), bottom nut (9), central shaft (10), bearing (11), body (12), big belt pulley (13), frame (14), it is characterized in that having an end and be connected, the spring (1) that the other end is connected with frame (14) with pallet (6).

2, a kind of high-speed grinder as claimed in claim 1, the quantity that it is characterized in that spring (1) is more than four or four.
