Abstract
The invention discloses a fast hold-down device for a sample pulverizer. The hold-down device comprises claws, a locking handle, a locking rotating shaft and a locking pedestal, wherein, the locking rotating shaft is arranged to pass through through-holes in the claws and drive the claws to do up-and-down movement, the top of the locking rotating shaft is connected with and rotates with the locking handle, and the bottom of the locking rotating shaft is provided with a clamp connection part which matches with the locking pedestal after descending and rotating at a certain angle. The invention has the advantages of simple and compact construction, low cost, more convenient and faster operation, good reliability, etc.
Description
Technical field
The present invention is mainly concerned with the sample making apparatus field, refers in particular to a kind of hold down gag of sample pulverizer.
Background technology
Sample pulverizer mainly is comprised of systems such as cabinet, frame, reducing mechanism, hold down gag, motor and electrical controls, and material is positioned in the reducing mechanism on the frame, and hold down gag is implemented to compress to reducing mechanism when work.Sample pulverizer mainly is to be used for comminuting matter by vibration impact and frictional force, at first material is put into the material alms bowl of sealing, is provided with breaking ring, broken excellent in the material alms bowl; When driven by motor offset assembly High Rotation Speed, can form vibration impact and frictional force, thereby material is made powdery.
On traditional sample pulverizer, the spiral way that generally adopts hold down gag realizes the compression to the material alms bowl, whole operating process is time-consuming, effort, have larger mechanical oscillation during simultaneously owing to sample pulverizer work, this mechanical oscillation easily make nut Hui Song, cause the material alms bowl to compress, cause dangerous situations such as flying alms bowl, the reliability of complete machine, security existing problems.
Summary of the invention
The technical problem to be solved in the present invention just is: for the technical problem that prior art exists, the invention provides the fast compressing device that is used for sample pulverizer of a kind of simple and compact for structure, with low cost, faster and more convenient operation, good reliability.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind of fast compressing device for sample pulverizer, comprise claw, set lever, locking rotating shaft and locking bed, described locking rotating shaft is arranged in the through hole of claw and can moves up and down with claw, the top of described locking rotating shaft links to each other with set lever and can rotate with set lever, the Access Division that the bottom of described locking rotating shaft is provided with in decline and is used for after rotating to an angle cooperating with locking bed.
As a further improvement on the present invention:
Described Access Division has cammed surface.
Described locking bed is arranged on the support.
Be provided with return spring between described Access Division and the sample pulverizer platform.
One end of described claw is slidedly arranged on the support and along support and moves up and down.
Compared with prior art, the invention has the advantages that: the present invention is used for the fast compressing device of sample pulverizer, only by rotation, just can make the Access Division of locking rotating shaft bottom realize cooperating with locking bed, plays the effect that compresses the material alms bowl; Otherwise, also only just can realize loosening by rotation, whole operating process is quick, convenient, and good reliability is safe.

The specific embodiment
Below with reference to Figure of description and specific embodiment the present invention is described in further details.
Embodiment 1: as shown in Figure 1, Figure 2, Figure 3 and Figure 4, the present invention is used for the fast compressing device of sample pulverizer, comprise claw 1, set lever 2, locking rotating shaft 3 and locking bed 4, claw 1 is used for material alms bowl 9 is compressed, locking rotating shaft 3 is arranged in the through hole of claw 1, locking rotating shaft 3 can move up and down with claw 1, but can not rotate with claw 1 when rotated, is provided with back-up ring at the limit travel place of claw 1 lifting in the locking rotating shaft 3.The top of locking rotating shaft 3 links to each other with set lever 2 and can rotate with set lever 2, the Access Division 5 that the bottom of locking rotating shaft 3 is provided with in decline and is used for after rotating to an angle cooperating with locking bed 4.
When needs material alms bowl 9 when compressing, is depressed first locking rotating shaft 3, then the rotational lock handle 2, drive locking rotating shaft 3 and rotate, make Access Division 5 drop to locking bed 4 under the position, Access Division 5 is cooperated with locking bed 4.At this moment, claw 1 also drops to the height that compresses material alms bowl 9 simultaneously.
When needs loosened compression to material alms bowl 9, reverse rotation set lever 2 drove locking rotating shaft 3 and rotates, make Access Division 5 break away from locking beds 4 under the position, Access Division 5 is separated with the cooperation of locking bed 4.On carry set lever 2, claw 1 also rises to the height that break away to compress material alms bowl 9 simultaneously.
In the present embodiment, Access Division 5 has cammed surface 51, and this cammed surface 51 can make Access Division 5 tightr with cooperating of locking bed 4, greatly improves its reliability.
In the present embodiment, locking bed 4 is arranged on the support 6, is provided with return spring 8 between Access Division 5 and the sample pulverizer platform 7, can allow the return of locking rotating shaft 3 and claw 1 more light, quick by return spring 8.
Embodiment 2: as shown in Figure 5 and Figure 6, the structure in the present embodiment and embodiment 1 are basically identical, and difference just is: an end of claw 1 is slidedly arranged on the support 6 and along support 6 and moves up and down.
Below only be preferred embodiment of the present invention, protection scope of the present invention also not only is confined to above-described embodiment, and all technical schemes that belongs under the thinking of the present invention all belong to protection scope of the present invention.Should be pointed out that for those skilled in the art, the some improvements and modifications not breaking away under the principle of the invention prerequisite should be considered as protection scope of the present invention.
