Description
Technical Field
The utility model relates to a screening plant of airtight handing-over of sample belongs to machinery.
Background
In the preparation process of powder such as mineral, soil, traditional Chinese medicine and the like, the sample is usually required to be dried, ground, sieved and the like, so as to prepare a qualified powder standard sample. In the existing sample preparation instrument, the sample is often transferred by pouring or arranging an inclined channel, dust and sample loss are easily formed, and the sample is not easy to clean.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a screening plant of airtight handing-over of sample realizes the airtight butt joint of sample jar and sieve, need not to empty the sample, can not produce the raise dust.
The screening device for sample closed handover comprises a screen, a sample tank, a material receiving hopper, a rotary driver, a base plate, a lifting cylinder, a screening sliding table, a switch valve cylinder and a screening motor;
the substrate is connected with the rotary driver; the screening sliding table is movably connected with the base plate through a vertical guide rail and driven by a lifting cylinder; the screening motor is connected with the screen; one end of the sieve is fixedly connected with the receiving hopper, and the other end of the sieve is butted with the sample tank; a discharge port of the receiving hopper is provided with a switch valve which is driven by a switch valve cylinder to open and close;
in an initial state, the sieve and the receiving hopper are arranged above the sieving sliding table in a back-off mode, and after a sample tank containing a sample is placed on the sieving sliding table, the lifting cylinder drives the sieving sliding table to move upwards, so that the open end of the sample tank is in butt joint with the sieve; then, the rotary driver drives the base plate to rotate 180 degrees, and then the sieving motor drives the sieve to perform sieving operation.
Under the specific circumstance, the screening motor is fixedly installed on the base plate, the screening motor is connected with the screen through the connecting rod mechanism, and the screen is connected with the base plate in a sliding mode through the horizontal guide rail.
Under the specific condition, still be provided with sample tank positioning mechanism on the screening slip table.
According to the utility model discloses a screening plant of airtight handing-over of sample realizes the airtight butt joint of sample jar and sieve, need not to empty the sample, can not produce the raise dust.
Drawings
Fig. 1 is a schematic perspective view of the sieving device for sample airtight handover according to the present invention in an initial state;
fig. 2 is a schematic perspective view of the sieving status of the sieving device for sample airtight handover of the present invention.
Detailed Description
The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.
Referring to fig. 1-2, the screening device according to the present invention mainly comprises a screen 5, a sample tank 10, a receiving hopper 6, a rotary driver 1, a base plate 2, a lifting cylinder 3, a screening sliding table 4, a switch valve 7, a switch valve cylinder 8 and a screening motor 9;
the substrate 2 is connected with the rotary driver 1, and the rotary driver 1 can adopt a motor specifically; the screening sliding table 4 is movably connected with the base plate 2 through a vertical guide rail 11 and is driven by a lifting cylinder 3; the screening motor 9 is connected with the screen 5; one end of the sieve 5 is fixedly connected with the receiving hopper 6, and the other end is used for being butted with the sample tank 10; the discharge port of the receiving hopper 6 is provided with a switch valve 7 which is driven to open and close by a switch valve cylinder 8.
And a sample tank positioning mechanism is further arranged on the screening sliding table 4, for example, a groove or a convex point matched with the bottom of the sample tank is arranged, so that the sample tank 10 is accurately positioned when placed, and is conveniently butted with the sieve 5.
Referring to fig. 1 specifically, in an initial state, a sieve 5 and a receiving hopper 6 are arranged above a sieving sliding table 4 in a back-off manner, and after a sample tank 10 containing a sample is placed on the sieving sliding table 4, a lifting cylinder 3 drives the sieving sliding table 4 to move upwards, so that the open end of the sample tank is in butt joint with the sieve; then, the rotary driver 1 drives the base plate 2 to rotate 180 degrees (see fig. 2), and then the screen 5 is driven by the screen motor 9 to perform a screening operation.
It is specifically intended that the embodiments described above be illustrative rather than limiting. All changes and modifications that come within the spirit and scope of the invention are desired to be protected.
