The invention discloses a multifunctional potato woven bag, which comprises a bag body, the bag body is formed by compressing and bonding multiple layers of bags, several leak holes are opened around the bottom of the bag body, and the inner wall of the leak hole passes through An iron ring is fixedly pasted and connected, and the bottom of the bag body is provided with a stabilizing device, and the stabilizing device is fixed in the interlayer of the bag body through sewing, and a group of hand straps are fixed on the left and right sides of the bag body, and the bag body is There is a bag opening on the side, and a sealing strip is provided on the lower side of the pocket opening, and the sealing strip one moves through the interlayer of the bag body on the lower side of the pocket opening, and a sealing strip is provided on the bag body on the lower side of the sealing strip Two, and the two sealing strips run through the interlayer of the bag body on the lower side of the bag mouth, and the inside of the bag body is provided with a sponge protective layer one. The woven bag of the present invention not only guarantees the colorless, odorless and non-toxic environmental protection concept in terms of materials, but also enhances fast closing, size classification, impurity screening and perfect bag body protection in terms of functions.

The invention provides an impurity removing vibrating screen for peony seeds, which comprises a rack, a driving motor, a screen body, a screen net and a vibrator. The screen net comprises an upper screen net body and a lower screen net body. The upper screen net body is composed of a left half net body and a right half net body which form an included angle of 176 degrees, and is provided with a plurality of first through holes and a plurality of transverse corrugated protrusions. The diameter of the first through holes is 3 mm larger than the diameter of the mature peony seeds. The height and the thickness of all the transverse corrugated protrusions are 3 mm. The lower screen net body is provided with second through holes of which the diameter is 2 mm. The screen body is provided with a front rotating shaft and a back rotating shaft. A transmission mechanism is arranged between the front rotating shaft and the back rotating shaft. Two sets of material spreading and flow guiding devices are arranged on the transmission mechanism with each comprising a material spreading plate composed of a left push plate and a right push plate which form an included angle of 150 degrees and a flow guiding plate composed of a left guide plate and a right guide plate which form an included angle of 150 degrees. The bottoms of the material spreading plates and the bottoms of the flow guiding plates are matched with the top surface of the upper screen net body in shape. The distance between the bottoms of the material spreading plates and the top surface of the upper screen net body as well as the distance between the bottoms of the flow guiding plates and the top surface of the upper screen net body are 12 mm. The impurity removing rate can be reached only by screening the peony seeds for one time, and thus the production efficiency is greatly improved.

The invention provides a cell separation chip based on the silicon structural on an insulator, which is composed of two layers combined mutually, wherein the first layer is a path layer, and the second layer is a cover plate layer. A micro-structure is formed in the path layer through engraving a groove on SOI silicon chip, the path layer is provided with a micro channel, a liquid storage tank, a fiber optic groove and a micro electrode couple structure, and the liquid storage tank on the path layer is used for sieving the former and the later sample liquids and storing sheath flow liquid; the micro channel is unimpeded, and is used for sample (cell suspension or solution) flow; fiber optic provides an optical detecting circuit; the micro electrode couple is used for realizing cell sieving. An injection port and a sample delivery port on the cover plate layer are connected with an external pipe. The information of the cell volume can be obtained by fiber optic for distinguishing whether the cell is a fused cell or not, alternating current photo-electric signals are applied on the micro electrode couple correspondingly, deflection is caused on cells, thus the cell separation is realized. The electric field is adopted by the chip for performing non-contact sieving and separating operation, thus the survival rate of live cells is enhanced, the structure is simple, the process is convenient and the cost is low.

The invention discloses a metal powder screening machine for additive manufacturing, which includes a bottom plate, a support rod and a movable plate; the bottom plate: supporting legs are arranged at four corners of the lower surface, and two fixed plates are respectively installed at the left and right ends of the upper surface of the bottom plate, And the front and rear ends of the upper surface of the fixed plate are respectively provided with vibrating motors, a fixed frame is arranged between the opposite surfaces of the vibrating motors on both sides, and the upper end of the fixed frame is provided with a sieve plate, and the upper surface of the fixed frame is provided with a sieve plate. The sieve hole corresponds to the diversion hole, and the front end of the sieve plate is handed over with a side baffle and a vibrating sieve plate, which can automatically sieve the material and reduce the manual operation steps, so that the screening efficiency is higher, and it can Clean the screen to avoid screen clogging and affect the screening efficiency of the material. At the same time, the equipment can stir the material when screening the material to ensure that the material can fall evenly during screening and avoid material accumulation that affects the screening efficiency.
