Description

Grinding device convenient to carry

Technical Field

The invention belongs to grinding equipment, and particularly relates to a small and portable grinding device.

Background

The general grinder has the disadvantages of complex structure, large volume, heavy weight, external power supply and inconvenient carrying and outdoor use. When a researcher needs to grind in the field for collecting articles, the traditional grinding equipment is not easy to carry, and cannot carry out grinding operation on the spot, so that the efficiency is low.

Disclosure of Invention

The invention aims to provide a portable grinding device suitable for field use.

The invention is realized by the following technical scheme:

a portable grinding device comprises a storage part for storing ground articles, a driving mechanism for driving the storage part to move and a portable power source for driving the driving mechanism to move, wherein a cavity for storing the ground articles is arranged in the storage part, grinding beads are arranged in the cavity, and the power source drives the driving mechanism to drive the storage part to move under the working condition, so that the grinding beads in the cavity of the storage part impact the ground articles to grind.

The invention has the beneficial effects that: the portable grinding device drives the driving mechanism to move through the portable power source, then drives the grinding beads in the storage part to move, generates impact force through the movement of the grinding beads, and realizes the grinding effect of articles in the cavity.

Detailed Description

Examples

Fig. 1 and 2 show a portable grinding device, which is particularly suitable for field use, the power source in the grinding device is a battery 1, the grinding device includes a storage component 2 for storing the ground object, a driving mechanism for driving the storage component 2 to move, and a portable power source for driving the driving mechanism to move, in this embodiment, the power source is the battery 1, the battery can be various batteries on the market, the battery is electrically connected with a motor, in this embodiment, the storage component 2 is a supporting component fixed on a moving component 3, the storage component 2 is connected with a test tube (not shown in the figure), in this embodiment, the test tube is embedded or clamped in the storage component 2, the test tube is detachable, and the ground object and the grinding bead (not shown in the figure) are arranged in the test tube. The power source drives the driving mechanism to drive the storage part 2 to move under the working condition, so that the grinding beads in the cavity of the storage part 2 move to impact the ground objects to grind.

In order to facilitate the putting in or taking out of the grinded article, the grinded article is placed in the test tube, so the storage member 2 is designed as a support member fixed on a movable member 3, the storage member is connected with the test tube, and the grinded article and the grinding bead are arranged in the test tube.

In order to make the ground object generate reciprocating motion, the driving mechanism comprises a motor 4, a mounting plate 5 and a rotating part 6, the motor 4 is mounted on the mounting plate 5, the rotating part 6 is in shaft linkage fit with the motor 4, the moving part is one, one end of the moving part is connected to the eccentric position of the rotating part 6, the other end of the moving part is movably arranged on the mounting plate 5, and the storage part 2 is fixed at the middle position of the connecting rod. The motor 4 drives the rotating piece 6 to rotate, so that the rotating piece 6 is driven to move at an eccentric position, the storage piece 2 is driven to reciprocate, and grinding balls impact ground objects to grind the ground objects. The storage component is arranged in the middle of the connecting rod, so that the movable component can move in four directions during movement, specifically, the movable component can reciprocate along the following guide rail direction and two directions vertical to the guide rail direction, and an elliptic orbit movement track is formed during movement. Thus, the grinding effect is better.

In order to support the storage element 2 and to reduce friction during movement of the storage element 2, a linear sliding module is provided on the storage element 2 or at one end of the storage element 2. The linear sliding module comprises a sliding block 8, a guide rail 9 and a connector 7, wherein the connector 7 is arranged in a penetrating mode, one end of the connector 7 is fixedly connected with the sliding block 8, and the guide rail 9 of the linear sliding module is fixed on the mounting plate 5. The setting of sharp module can reduce the resistance that produces when storage 2 activity friction, makes the product laborsaving, the power saving.

In order to realize that the rotating piece 6 can drive the reciprocating motion when rotating, a convex column 61 is arranged at the eccentric position of the end surface of one side of the rotating piece 6 and is sleeved on the convex column 61. A bearing is arranged between the convex column 61 and the convex column. In this embodiment, the protruding column 61 and the rotating member 6 are integrated, the center of the rotating member 6 is connected to the motor shaft, the rotating member 6 penetrates the mounting plate 5, and a bearing is disposed between the rotating member 6 and the mounting plate 5. In order to enable a better relative rotation between the connection head 7 and the connection head, a bearing is provided between the connection head 7 and the connection head.
