Description

Detachable handheld crusher

Technical Field

The invention relates to the field of laboratory equipment, in particular to a detachable handheld crusher.

Background

Technical background: at present in the placenta preparation process, generally use ordinary operation scissors preparation to cut into pieces, can only single operation at every turn, the great waste time resource in this preparation process, manpower resources, lead to the preparation time overlength, the too big a condition of manpower consumption, in order to improve work efficiency, can increase the staff and operate, with the waste of reducing time resource, but manpower resources have been wasted so, and personnel all operate at a biological safety cabinet, greatly increased the probability of pollution, do not also do benefit to batch operation, and the cost is increased.

The most recent technical scheme currently available is as follows: in the prior art, a small part is crushed by using a traditional refiner, but the refiner has very high purchase cost, high material consumption and inconvenient cleaning of equipment, one refiner can only operate one sample at a time, the equipment needs to be cleaned independently after the operation is finished, the equipment is inconvenient to sterilize and disinfect, the next sample cannot be prepared immediately, and the preparation method is easy to cause pollution and is more unfavorable for large-batch sample preparation and production.

Disclosure of Invention

The invention aims to solve the technical problem that the refiner has good effect, but for enterprises, the refiner has high cost and is unrealistic to operate and produce in batches. The operation of the common surgical scissors needs a large amount of manpower, and the tissue breakage rate is very low, so that the product is unstable, and the waste of manpower and materials is caused.

In order to solve the technical problems, the invention adopts the following technical means:

a detachable hand-held crusher comprising a crusher body; the crusher body be hand-held device, starting drive, rotary device, gear train, turbine device hand-held device include handle and base, handle department is equipped with starting drive, starting drive for starting drive gear, tensile hook, nut and extension spring, starting drive gear connects driven gear train, the turbine device is connected to the other end of gear train, the turbine device be bearing, turbine fixing device and draw-in groove device. The manpower consumption and the refiner purchase cost that manual shearing and crushing caused are reduced, the percentage of damage is stably controlled, the operation pollution probability is reduced, the material consumption and the preparation time are reduced, and the work efficiency is improved. The common refiner can be more convenient and faster, the use convenience of the refiner is kept, the use process is more convenient and quicker, the working efficiency is improved, the shearing degree is improved, and the overlong preparation time and the waste of reagent consumables caused by human factors and equipment reasons are reduced. And the detachable handheld crusher does not need to be charged and can be used at any time.

Preferably, the further technical scheme of the invention is as follows:

the bearing divide into first bearing and second bearing, first bearing and second bearing set up respectively at turbine fixing device both ends, the draw-in groove device is connected to the second bearing other end, the draw-in groove device be the spacing draw-in groove of turbine device.

The turbine device, the gear of the gear set and the gear fixing device are all made of PPS.

The working steps of the detachable handheld crusher are as follows:

step 1: starting: the detachable handheld crusher is characterized in that a handle of the handheld device is held by a hand, and the starting device is pressed by the hand to drive a starting gear connected with the starting device;

step 2: transmission: the starting gear drives the eighth gear to rotate, the eighth gear and the seventh gear are fixed on the handheld device through nuts, the eighth gear rotates to drive the seventh gear, the seventh gear rotates to drive the sixth gear, the sixth gear and the fifth gear are fixed on the handheld device through nuts, the sixth gear rotates to drive the fifth gear to rotate, the fifth gear rotates to drive the fourth gear to rotate, the fourth gear and the third gear are fixed on the handheld device through nuts, the fourth gear rotates to drive the third gear to rotate, the third gear rotates to drive the second gear to rotate, the second gear and the first gear are fixed on the handheld device through nuts, and the first gear is driven to rotate;

and step 3: the turbine rotates: the first gear rotates to drive the turbine device to rotate, and the lower end of the turbine device is provided with a clamping groove device which can connect the turbine device with the rotating device to drive the rotating blade to rotate;

and 4, step 4: disassembling and cleaning: after the use is finished, the rotating device is disassembled to be cleaned and sterilized, and the handheld device is placed on the base;

and 5: and (3) recycling: the handheld device can be matched with a plurality of rotating devices, and the rotating devices can be detached independently for cleaning, disinfection and sterilization and can be recycled for multiple times.

This can dismantle handheld broken pulp grinder becomes the hand-held type with traditional seat formula, inserts the electricity operation, the back operation of charging becomes and need not the power, can use at any time, uses convenient and fast more to become detachable with rotary device, can dismantle the washing and sterilizing at any time after using, follow-up can continue to use, not only reduce cost's consumption also can reduce the consumption of artifical physical power, makes preparation speed promote, is fit for mass production preparation more.

Advantages and effects of the invention

1. The traditional seat type is changed into a handheld type, so that the appearance of the automatic suction aid is similar to that of an automatic suction aid of a common instrument in a laboratory, and strangeness is avoided;

2. the rotating device can be detached and cleaned independently, and the handheld device can not influence subsequent operation and can not cause cross contamination among samples when being used continuously.

3. Simplifies and stabilizes the placenta cutting preparation process, can control the breakage rate, reduces the material cost and the preparation time, and improves the working efficiency.

4. The device need not to charge and insert the electricity operation for it is more convenient to use.

The detachable handheld slurry crushing machine is directionally used in the field of medicine, particularly in the field of cell experiments, in the prior art and crushers in the market, under the control of a motor, the rotating crushing force is often too large, crushing with different force cannot be performed according to different experimental samples, and the detachable handheld slurry crushing machine cannot be used in the field of experiments.
