[0001] The invention relates to a plant crushing device for extracting juice in biological experiments, in particular to a plant crushing device for extracting juice in biological experiments applied in the crushing device field. Background Art

[0002] Plant crushing devices are widely used in biological experiments. By efficiently crushing plant tissues, the devices provide strong support for the extraction of biological components such as cells, nucleic acids, and proteins.

The invention uses an extraction device to complete continuous plant preheating and crushing, solvent extraction, centrifugal separation, membrane filtration, and distillation. The preheating and crushing process preheats the plant; steam heating combined with ultrasonic oscillation allows the solvent and steam to exchange heat and heat up; ultrasonic oscillation causes strong cavitation and emulsification of the solvent; the impact force and negative pressure suction generated by the explosion of tiny cavitation bubbles break the plant cell wall and accelerate the release rate of natural components; centrifugal separation and membrane filtration are used to obtain an extract with high natural component content and low impurity content; gas phase condensation is used to obtain a regenerated solvent that participates in solvent extraction again, which saves extraction costs and is conducive to the high-yield extraction of natural components.

DETAILED DESCRIPTION

[0033] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0034] The first implementation method:

[0035] Figure 1-7 A plant crushing device for extracting juice from biological experiments is shown, comprising a processing platform 1, on which a crushing end 2 and an extraction end 3 are installed; the crushing end 2 comprises a bracket 21 and a crushing tank 22, a feeding pipe 23 communicating with the crushing tank 22 is installed at the side end of the bracket 21, a stirring rod and a crushing blade are rotatably connected in the crushing tank 22, a guide pipe 231 communicating with the output end of the crushing tank 22 is installed in the feeding pipe 23, and a feeding screw is passed through the feeding pipe 23; the feeding screw is an electric screw in the prior art, and the speed of the feeding screw is adjustable;

[0036] One end of the material delivery pipe 23 is plugged into the butt joint pipe 24, a pair of electric push rods are connected between the two ends of the butt joint pipe 24 and the material delivery pipe 23, and one end of the butt joint pipe 24 inserted into the material delivery pipe 23 is installed with a filter pipe 241 matching the guide pipe 231;

[0037] The outer end of the feeding pipe 23 is provided with an exhaust fan 7, on which a suction pipe inserted into the feeding pipe 23 is provided, and inside the exhaust fan 7 is provided a recovery bag communicated with the suction pipe; the exhaust fan 7 recovers the plant residues in the filter tube 241 and the feeding pipe 23 by exhausting air, so as to assist the self-cleaning of the device and the recovery of plant debris;

[0038] A water pipe is passed through the bracket 21, and two branch pipes are connected to the water pipe. The output ends of the two branch pipes are respectively located at the input end and the output end of the guide pipe 231. The water pipe is used to input water into the guide pipe 231 to facilitate self-cleaning of the device. It is easy to clean the feed screw in the guide pipe 231 to avoid other plant samples remaining in the feed screw when replacing the plant sample for extraction, thereby affecting the accuracy of the experiment.

[0039] A through hole is formed at one end of the feed pipe 23, a clamp ring 232 is connected to the bottom end of the through hole, and a filter cover 25 is clamped inside the clamp ring 232; the filter cover 25 includes an outer cover body 251, a plurality of drainage holes are formed at the bottom end of the outer cover body 251, a clamp ring is installed at the outer end of the outer cover body 251, an inner cover body 252 is detachably installed at the inner end of the outer cover body 251, and a plurality of evenly distributed filter holes are formed on the inner cover body 252;

[0040] A plurality of fixing bolts 233 are plugged into the clamp ring 232. One end of the fixing bolt 233 penetrates the clamp ring 232 and is clamped with the filter cover 25. A pressure sensor is installed on the fixing bolt 233. The other end of the fixing bolt 233 is slidably connected to the bottom end of the feed pipe 23.

[0041] The extraction end 3 includes a lifting platform 31, a rotating disc 32 is rotatably connected to the movable end of the lifting platform 31, a motor matching the rotating disc 32 is installed on the lifting platform 31, and a pressurizing column 4 and a grinding column 5 are installed on the rotating disc 32;

[0042] The pressurizing column 4 comprises a cylinder, a pressure plate 41 matching the filter cover 25 is installed at the power output end of the cylinder, and the grinding column 5 comprises a servo motor, a rotating shaft is installed at the power output end of the servo motor, and a grinding roller 51 is fixedly connected to the top side end of the rotating shaft.

[0043] Optionally, the filter holes are formed on the side wall of the inner cover body 252, and the distance between the outer end of the inner cover body 252 and the inner wall of the outer cover body 251 is 1-2 cm.

[0044] An electric guide rail is connected between the processing platform 1 and the extraction end 3. An extraction tube 6 is placed on the movable end of the electric guide rail. A pipe rack is installed on the movable end. The inner diameter of the extraction tube 6 is larger than the outer diameter of the filter cover 25. A pressure sensor can be set on the movable end. After the extraction tube 6 is placed on the movable end, the electric guide rail automatically works to move the extraction tube 6 to the lower side of the filter cover 25, and then the device performs the damaged extraction work again.

[0045] When this solution is working, the plants are first broken by the breaking blades in the breaking tank 22, and the broken plant particles are transported to the butt joint 24 through the feeding pipe 23 and the feeding screw;

[0046] After the butt joint pipe 24 of the present solution is inserted into the feed pipe 23, the end surface of the filter pipe 241 is fitted with the end surface of the guide pipe 231, and the filter pipe 241 is located on the upper side of the filter cover 25; after the plant particles output by the feed pipe 23 enter the filter pipe 241, they are filtered and fall into the filter cover 25;

[0047] When the output of the crushing tank 22 reaches the set value, the extraction work is ready; at this time, the electric push rod on the connecting pipe 24 works to separate the filter tube 241 from the guide tube 231 by a set distance L (L is greater than the outer diameter of the pressing plate 41 and the grinding roller 51). After the filter tube 241 is separated from the guide tube 231, the pressurizing column 4 or the grinding column 5 can be inserted into the observation hole;

[0048] During extraction, the plant fragments in the filter cover 25 are pressurized or ground using the pressurizing column 4 or the grinding column 5 according to the user's choice to extract the juice;

[0049] When the pressurizing column 4 is used, the lifting platform 31 is controlled to make the turntable 32 rise to a set height, and then the turntable 32 is driven to rotate at a set angle to align the pressurizing column 4 with the through hole, and then the lifting platform 31 is lowered to a height h1 to insert the pressurizing column 4 into the through hole. When the cylinder is working, the pressing plate 41 continuously pressurizes and extracts the plant pieces in the filter cover 25, and the squeezed and extracted plant juice is discharged through the filter holes of the inner cover body 252, and finally discharged into the extraction tube 6 through the drainage holes of the outer cover body 251;

[0050] When using the grinding column 5, the lifting platform 31 is controlled to make the turntable 32 rise to the set height, and then the turntable 32 is driven to rotate the set angle to align the through hole of the grinding column 5, and then the lifting platform 31 is lowered to insert the grinding column 5 into the through hole until the pressure monitoring value at the fixing bolt 233 reaches the set value. At this time, the grinding roller 51 maintains the set pressurized pressure on the plant fragments in the inner cover body 252, and then when the servo motor works, the grinding roller 51 rotates and grinds the plant fragments on the inner cover body 252, and the plant juice extracted by grinding is discharged into the extraction tube 6.

[0051] This solution can facilitate the extraction of juice from a large number of experimental plants after crushing them, and can set a grinding or pressurized extraction method as needed, and extract through a fixed-capacity filter cover 25, which is easy to ensure that the plant fragments used for each extraction are similar, so as to meet the needs of using equal amounts of materials for extraction and adjusting a small amount of extraction in biological experiments;

[0052] Compared with the prior art which directly crushes the plant sample as a whole for extraction and then adjusts the juice, this embodiment is convenient for controlling the amount of plant crushed pieces used during extraction, is easy to save experimental samples compared with the prior art, and is convenient for continuous multi-batch extraction.

[0053] Second implementation method:

[0054] Figure 8 As shown, an extraction control system is also included, and the extraction control system includes a processor installed on the processing platform 1, and the processor is connected to a control module, a data processing module, and a monitoring module;

[0055] The control module is used to control the operation of the crushing tank 22, the feeding screw, the exhaust fan 7, the extraction end 3, the pressurizing column 4, the grinding column 5 and the electric guide rail. The control module receives the control instructions from the processor and drives each actuator to operate according to the preset program, such as the crushing tank 22 and the extraction end 3;

[0056] The control module supports multiple control modes, such as timing control, quantitative control, manual control, etc., and has a fault alarm function.

[0057] The data processing module receives monitoring data from the monitoring module, such as pressure sensor readings, motor speed, temperature inside the crushing tank, etc. The data processing module analyzes and processes the monitoring data and generates a statistical report of the extraction process.

[0058] The monitoring module monitors various parameters during the extraction process in real time, including but not limited to pressure, temperature, humidity, motor speed, liquid flow, etc.

[0059] The pressure sensor on the fixing bolt 233 is used to monitor the pressure state of the filter cover 25. On the one hand, it prevents the filter cover 25 from being damaged due to excessive pressure, and on the other hand, it ensures that the plant fragments in the filter cover 25 are subjected to sufficient pressure during extraction; the monitoring module monitors various parameters of the extraction process in real time, and the pressure sensor on the fixing bolt 233 monitors the pressure data of the filter cover 25 and uploads it to the monitoring module.

[0060] Optionally, the control module can set the grinding column 5 to match the position of the through hole when it is in the initial state, and before preparing for the extraction work, first control the grinding column 5 to level the plant fragments. During the leveling process, the grinding column 5 is driven down to match the upper surface of the filter cover 25, and the grinding roller 51 rotates at this time to evenly level the plant fragments accumulated in the filter cover 25;

[0061] The control module is provided with a self-checking mode for the process of feeding the plant pieces to the filter cover 25. The self-checking mode is used to detect whether the material in the filter cover 25 meets the requirements. In the self-checking mode, each time the feeding screw delivers a set amount of plant pieces, the filter tube 241 is controlled to be temporarily separated from the guide tube 231. After the filter tube 241 is separated from the guide tube 231, the grinding column 5 is driven to drop to a set height, and then the detection value of the pressure sensor on the fixing bolt 233 is checked. If the pressure is greater than the set value, it is determined whether the plant pieces between the filter cover 25 and the bottom end of the grinding column 5 are fully filled, and the extraction work can be carried out at this time;

[0062] If the pressure is less than the set value, the filter tube 241 and the guide tube 231 are controlled to return to their original positions, and the feeding screw is continuously controlled to feed the material.

[0063] The extraction control system realizes the comprehensive automatic control, data monitoring and processing of the juice extraction process in the plant crushing device. The functions of each module are clear and well-defined, and they are closely related to each other, forming an efficient and accurate extraction system. The system not only improves the extraction efficiency and accuracy, but also provides a more convenient and intelligent operation experience for experimenters.

[0064] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
