DETAILED DESCRIPTION

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Example: like Figure 1-6 As shown, a stirring device for citrus psyllid dsRNA nano nucleic acid insecticide comprises a base 1, a top center of the base 1 is provided with an involute lifting device 2, the involute lifting device 2 is provided with two vertical lifting ends, the two vertical lifting ends are fixedly installed with an oscillating stirring device 8 and a quick-release magnetic sleeve frame 6 in sequence from top to bottom, the oscillating stirring device 8 comprises a plurality of coil oscillating structures 82 arranged in a rectangular array, the quick-release magnetic sleeve frame 6 is provided with a plurality of oscillating magnetic sleeves 7 in a detachable rectangular array, each coil oscillating structure 82 corresponds to each oscillating magnetic sleeve 7, and a magnetic rod 84 is fixedly installed at the bottom of the coil oscillating structure 82; Quick clamping arms 3 are provided on both sides of the top of the base 1. The two quick clamping arms 3 are symmetrically arranged with the center of the base 1 as the origin. A detachable clamping and positioning test tube support plate 4 is provided between the two quick clamping arms 3. Test tubes 5 are provided on the surface of the test tube support plate 4 corresponding to each oscillating magnetic sleeve 7. The magnetic rod 84 and the oscillating magnetic sleeve 7 are synchronously driven by the involute lifting device 2 to approach or move away from the corresponding test tube 5. The magnetic rod 84 is inserted into the oscillating magnetic sleeve 7, and the oscillating magnetic sleeve 7 is inserted into the test tube 5.

[0020] Specifically, Figure 1-2As shown, by setting an involute lifting device 2, and driving each slider 24 on the linear guide 23 to move gradually closer or farther away synchronously, the oscillating stirring device 8 and the quick-release magnetic sleeve frame 6 are driven to move synchronously closer or farther away from the test tube support plate 4, thereby realizing the synchronous operation of inserting the magnetic rod 84 into the oscillating magnetic sleeve 7 and the oscillating magnetic sleeve 7 into the test tube 5 from top to bottom. At the same time, through the involute lifting device 2, the distance between the magnetic rod 84, the oscillating magnetic sleeve 7 and the test tube 5 is pulled apart, thereby providing sufficient space for convenient replacement of the oscillating magnetic sleeve 7 and the test tube 5, which is fully automatic and completely free of structural interference, thereby benefiting the improvement of the performance of the equipment. At the same time, by symmetrically arranging two quick clamping arms 3 on both sides of the base 1, the test tube support plate 4 can be quickly clamped and replaced, thereby effectively improving the production efficiency of the stirring device; In addition, in order to make the stirring device have better customized stirring ability, it is achieved by setting a quick-release magnetic sleeve frame 6 and multiple coil oscillation structures 82 of the oscillation stirring device 8, and by integrating several oscillation magnetic sleeves 7 into a quick-release plate 61 to form a module, and by quickly disassembling and positioning several modules and the outer frame 62, the function of disassembling and replacing the oscillation magnetic sleeve 7 at any time is realized, so that after a batch of test tubes 5 are stirred, the oscillation magnetic sleeve 7 can be quickly replaced for the next mixing operation, so that the stirring device has higher production performance; and combined with the coil oscillation structure 82, each coil oscillation structure 82 is connected through a circuit board, and can be controlled by the controller 9 to achieve a single independent vibration, and the vibration frequency is controllable and adjustable, so as to meet the stirring device of the present invention. A variety of different products are stirred at a time, and are reasonably distributed to different liquids to be stirred as needed, thereby greatly improving the stirring effect, making the stirring device more powerful and more suitable for the user's production scenario. Secondly, since the vibration unit of the stirring equipment utilizes an electromagnetic coil, the equipment noise is greatly reduced, thereby effectively avoiding the harm caused by working noise to the operator. Since friction is reduced, the service life of the equipment is effectively extended, making the stirring device more durable and highly economical.

[0021] The oscillation stirring device 8 includes an installation shell 85, and multiple coil oscillation structures 82 are arranged inside the installation shell 85.

The middle of the coil assembly 822 is movably connected to a vibration rod core 821 , and the magnetic rod 84 is detachably fixedly installed at the bottom of the vibration core rod 821 .

[0023] Specifically, Figure 6 As shown, by installing the magnetic rod 84 at the bottom of the vibration rod core 821 through threads or other detachable connection methods, the main power unit of the stirring device is formed, which is easy to replace and clean, and each unit can move synchronously and operate independently, with highly customized operations, further improving the practicality and versatility of the stirring device.

[0024] The quick-release magnetic sleeve frame 6 includes an outer frame 62, and a plurality of L-shaped grooves 63 are equidistantly provided on the front and rear sides of the outer frame 62 along the length direction. A quick-release plate 61 is inserted between two opposite L-shaped grooves 63, and the end of the quick-release plate 61 is inserted into the transverse groove of the L-shaped groove 63. A locking pin 64 is provided at the top of the transverse groove, and a strong magnet 65 is embedded at the bottom of the inner wall of the transverse groove corresponding to the locking pin 64.

[0025] Specifically, Figure 2 , 4 As shown, a plurality of L-shaped grooves 63 are equidistantly provided on the two longer sides of the outer frame 62, and the two ends of the quick-release plate 61 are placed through the vertical grooves of the corresponding two L-shaped grooves 63, and then the vertical freedom is restricted by translating and snapping into the horizontal grooves of the L-shaped grooves 63. At the same time, in order to restrict the horizontal and vertical freedom of the quick-release plate 61, a locking pin 64 is detachably inserted in the horizontal slot corresponding to the L-shaped groove 63 at the top of the outer frame 62, and a strong magnet 65 is embedded in the corresponding position in the horizontal groove, and a magnetic part is arranged at the bottom of the locking pin 64 to adsorb the strong magnet 65.

[0026] The involute lifting device 2 includes a linear guide 23, a scissor-type telescopic frame 26 and a linear drive device. The linear guide 23 is fixedly installed in the center of the base 1 in the vertical direction. Two sliders 24 are slidably connected to the surface of the linear guide 23. The two sliders 24 are fixedly installed with a second ear plate 27 and a first ear plate 25 from top to bottom. The second ear plate 27 and the first ear plate 25 are fixedly installed with the oscillation stirring device 8 and the quick-release magnetic sleeve 6 respectively. The linear drive device is fixedly installed with the base 1 through the mounting bracket 21. The three hinge points on the same side of the scissor-type telescopic frame 26 are hinged to the second ear plate 27, the first ear plate 25 and the mounting bracket 21 from top to bottom respectively. The lowest hinge point on the other side of the scissor-type telescopic frame 26 is hinged to the telescopic end of the linear drive device.

[0027] Specifically, Figure 1-2 As shown, the linear drive device is an electric telescopic rod 22, which is fixedly mounted on the top of the mounting bracket 21. The electric telescopic rod 22 drives the scissor-type telescopic frame 26 to achieve telescopic action. Since the movement characteristics of the connecting joints of the scissor-type telescopic frame 26 are synchronous and equidistant gradual approach or distance, the quick-release magnetic sleeve frame 6 and the oscillating stirring device 8 are respectively installed through the first ear plate 25 and the second ear plate 27, so as to realize the corresponding insertion and extraction actions of the magnetic rod 84 and the oscillating magnetic sleeve 7, thereby realizing the opening and closing states of the stirring device, and providing sufficient operating space for the operator.

[0028] The quick clamping arm 3 includes a column 31, which is fixedly installed on one side of the top of the base 1. A clamping groove 32 is fixedly installed on the top of the column 31. The test tube support plate 4 is inserted between the two clamping grooves 32. A limiting structure is arranged in the clamping groove 32. The test tube support plate 4 is fixed to the limiting structure by sliding into the clamping groove 32, and the test tube support plate 4 is unlocked from the limiting structure by pressing and dragging.

[0029] The limiting structure includes two positioning columns 33, which are respectively fixedly connected to the two ends of the top of the inner wall of the clamping groove 32. Positioning holes 41 are opened at the four corners of the test tube support plate 4 and corresponding to the positioning columns 33. The positioning columns 33 are correspondingly inserted into the positioning holes 41. A spring pin 35 is fixedly installed in the center of the bottom of the clamping groove 32. The top of the telescopic rod of the spring pin 35 penetrates into the inside of the clamping groove 32 and is close to the bottom surface of the test tube support plate 4.

[0030] A pressing opening 34 is formed in the center of one side of the top of the clamping slot 32 , and the pressing opening 34 is in an arc shape.

[0031] Specifically, Figure 3 As shown, by inserting the side of the test tube support plate 4 into the clamping groove 32, the operator pushes forward and lightly presses downward, and the spring pin 35 is pressed back into the seat by the plate body, so that the test tube support plate 4 can be smoothly pushed into place, and then it is released, and the spring pin 35 rebounds and pushes up the test tube support plate 4, so that the positioning holes 41 at the four corners are plugged and limited with the corresponding positioning columns 33, thereby realizing the quick installation and positioning of the test tube support plate 4; When the test tube support plate 4 needs to be disassembled, the operator presses down the plate body at the pressing port 34 to separate the positioning hole 41 from the positioning column 33, and then the test tube support plate 4 can be dragged outward to achieve disassembly. The operation is simple and convenient, which simplifies the installation process of the test tube 5 and improves production efficiency.

[0032] The interior of the mounting shell 85 is poured with sealant, which completely seals the circuit board 83. Through the packaging process, the waterproof ability of the device can be effectively improved, so that the coil oscillation structure 82 is safer when powered on, effectively protecting the operator's life safety, while also protecting the normal use of the equipment, thereby extending the service life of the equipment.

[0033] It should be noted that the electrical control principle of the coil oscillation structure is a conventional circuit control principle, so it will not be elaborated here. Its specific circuit and control method are detailed in common knowledge and prior art.
