Description

Technical Field

[0001] The invention belongs to the technical field of emamectin benzoate extraction equipment, and particularly relates to an extraction device for emamectin benzoate from thin-shell pecans. Background Art

[0002] The thin-skinned pecan is a perennial deciduous tree of the genus Carya in the Juglandaceae family. Native to North America, the thin-skinned pecan tree stands tall, with gray-brown, longitudinally fissured bark, a well-developed taproot, and very few fibrous roots. Its fruit is oblong, speckled with dark brown spots. Its thin, easy-to-peel shell offers a high kernel yield and contains a variety of beneficial amino acids, vitamins B1 and B2, and its high nutritional value makes it an ideal food. To address existing pest problems, emamectin is widely used in thin-skinned pecan-growing areas. Emamectin, a derivative of the biopesticide avermectin, is highly effective, low-toxic, and low-residue. However, long-term use can still leave residues in the leaves, peel, and kernels of thin-skinned pecans. To detect emamectin residues in thin-skinned pecans, extraction and testing are necessary.

[0003] Currently, the extraction of emamectin benzoate from thin-shelled pecans usually requires crushing the walnuts, then spraying them with an extractant and stirring them to dissolve the emamectin benzoate. However, current equipment cannot screen out unsuitable walnut particles during crushing and mixing, resulting in particles of different sizes, which affects the extraction effect of emamectin benzoate. Moreover, simply spraying the extractant does not mix the pulp particles with the extractant well, making it difficult to fully mix them. Summary of the Invention

Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0026] like Figure 1-10As shown, the present invention provides an extraction device for emamectin benzoate from thin-shelled pecans, which includes: a frame 100, an extraction cylinder 200, at least one grinding component, a screening component, a stirring component and a driving motor 1001.

[0027] A rotating rod 700 is provided on the frame 100 , and a driving motor 1001 is provided on the top of the frame 100 . The driving end of the driving motor 1001 is connected to the top of the rotating rod 700 for driving the rotating rod 700 to rotate on the frame 100 .

[0028] The extraction cylinder 200 is arranged below the frame 100. The extraction cylinder 200 is connected to a discharge pipe for discharging the mixed liquid in the cylinder. A valve is installed on the discharge pipe, which is arranged at the bottom of the extraction cylinder 200.

[0029] In this embodiment, two grinding assemblies are provided and connected to the frame 100. The two grinding assemblies are stacked up and down. By providing multiple grinding assemblies, the pecan material can be fully ground. The material is poured from the top of the grinding assembly above the extraction cylinder 200, and is ground by the grinding assembly and then sent to the screening assembly below. The screening assembly is suspended between the grinding assembly and the extraction cylinder 200 , and the screening assembly includes a screen frame for receiving the material discharged from the bottom of the grinding assembly.

[0030] A plurality of stirring components are arranged at intervals around the rotating rod 700 extending into the extraction cylinder 200, specifically arranged in the extraction cylinder 200, for stirring the material in the extraction cylinder 200. The stirring components can be driven to rotate by other drive motors 1001. In this embodiment, driving by a reciprocating mechanism can save costs.

[0031] like Figure 5 、 6 As shown, the reciprocating mechanism is arranged on the rotating rod 700 and is located below the screening assembly. The reciprocating mechanism is driven by the drill rod to reciprocate up and down. A number of beating members are provided on the reciprocating mechanism. When the reciprocating mechanism moves back and forth along the axial direction of the rotating rod 700, it drives the beating members to contact and beat the bottom of the screen frame.

[0032] like Figure 6 As shown, a screening assembly is provided below the extraction cylinder 200, and the screening assembly is used to screen the ground particles. Particles of suitable size pass through the screen frame and enter the extraction cylinder 200 below, preventing inappropriate particles from entering the extraction cylinder 200 below. The stirring assembly is then used to stir the mixture of particles and extract in the extraction cylinder 200 to fully and evenly mix them, thereby accelerating the mixing of acetone water and walnut particles and the extraction of emamectin benzoate, thereby ensuring the extraction effect. At the same time, the reciprocating mechanism located below the screening assembly can also drive the beating member to beat the bottom of the screen frame to avoid blockage of the screen frame.

[0033] Specifically, the two grinding assemblies are stacked up and down in sequence, wherein the grinding assemblies include a grinding bucket and a grinding disc that cooperate with each other.

[0034] Specifically, it includes a first grinding disc 300 and a second grinding disc 400 fixedly connected to the outside of the rotating rod 700. A first grinding bucket 3001 is provided below the first grinding disc 300, and a second grinding bucket 4001 is provided below the second grinding disc 400. After the first grinding disc 300 and the first grinding bucket 3001 perform preliminary grinding on the walnuts, the second grinding disc 400 and the second grinding bucket 4001 perform further grinding on the walnuts.

[0035] The grinding hopper is connected to the frame 100, and the grinding disc is connected to the rotating rod 700. The grinding disc is in clearance with the grinding hopper, and a conical grinding surface is formed on the bottom of the grinding disc to match the grinding hopper. Walnuts enter the gap between the grinding hopper and the grinding disc, and the conical grinding surface and the grinding hopper grind and crush the walnuts. The funnel-shaped grinding hopper can gradually discharge the material during the grinding process and discharge the ground particles through the discharge port at the bottom of the grinding hopper. To ensure that the pecans enter the grinding bucket and the grinding disc smoothly, the outer edge of the grinding bucket is higher than the outer edge of the grinding disc, allowing the pecans to enter the grinding surface from the gap on the outer periphery.

[0036] The top of the grinding disc can be set to a cone with a high center and a low periphery, which makes it convenient for the material to roll along the conical surface into the space between the grinding disc and the grinding bucket.

[0037] In order to ensure smooth transfer of particles between multiple grinding components, a guide plate 3002 is provided between the two grinding components. The guide plate 3002 is fixedly connected to the bottom of the grinding bucket, and is connected between the discharge port of the upper grinding bucket and the feed port of the adjacent grinding disc below. That is, the top of the guide plate 3002 is connected to the discharge port of the upper grinding bucket, and the bottom of the guide plate 3002 corresponds to the lower grinding disc and the feed port of the outer edge of the grinding bucket, and the guide plate 3002 is tilted to ensure that the particles of the upper grinding component can be smoothly transferred to the lower grinding component.

[0038] like Figure 7 As shown, a connecting rod 3003 is fixedly connected to the bottom of the first grinding bucket 3001, and a guide plate 3002 is fixedly connected to the bottom of the connecting rod 3003. The walnut particles ground by the first grinding disc 300 are guided to between the second grinding disc 400 and the second grinding bucket 4001 through the guide plate 3002. In addition, the first grinding bucket 3001 and the second grinding bucket 4001 are both fixedly connected to the frame 100.

[0039] In this embodiment, Figure 6As shown, the screening assembly includes: a connecting cover 600 and a screen frame, wherein the screen frame is an annular screen frame with the rotating rod 700 at the center, and the middle is for the rotating rod 700 to pass through to avoid interference with the rotating rod 700.

[0040] The connecting cover 600 is arranged at the bottom of the lowest grinding assembly, and can be fixed to the bottom of the grinding bucket fixed in the grinding assembly through a connecting frame 6006, etc. The top of the connecting cover 600 corresponds to the bottom discharge port of the upper grinding assembly, and the discharge port discharges the material through the surface of the connecting cover 600. The outer edge of the connecting cover 600 is covered on the inner edge of the screen frame, and is used to receive the material from the discharge port of the grinding assembly to the screen frame, and the material rolls down to the lower screen frame through the surface of the connecting cover 600.

[0041] In order to improve the screening efficiency of the screening assembly, the screening assembly further includes: an annular plate 6001 and several elastic members, wherein the elastic members can be implemented by springs 6004 .

[0042] The annular plate 6001 is fixedly connected to the frame 100, and the annular plate 6001 is arranged corresponding to the outer edge of the screen frame. The annular plate 6001 can be arranged above or below the outer edge of the screen frame, and is arranged correspondingly to the outer edge of the screen frame. At the same time, the inner edge of the screen frame corresponds to the connecting cover 600. Since the connecting cover 600 needs to roll off the material on the surface, the outer edge of the connecting cover 600 is covered above the inner edge of the screen frame; like Figure 6 、 8 As shown, the elastic member adopts a spring 6004 and is arranged between the annular plate 6001 and the outer edge of the screen frame. At the same time, the elastic member is also arranged between the connecting cover 600 and the inner edge of the screen frame, and is used to elastically connect the screen frame with the connecting cover 600 and the annular plate 6001, so that the inner and outer circles of the screen frame can form elastic potential energy with the connecting cover 600 and the annular plate 6001. When the flapping member contacts the screen frame, elastic deformation is formed to avoid the flapping member from hard contact with the screen frame. The screen frame is set to an elastic connection method to cooperate with the impact of the flapping member to better screen the material in the screen frame.

[0043] Specifically, the screen frame includes: a first connecting ring 6002, a second connecting ring 6003 and an annular filter 6005. The first connecting ring 6002 is connected to the annular plate 6001 through an elastic member, the second connecting ring 6003 is connected to the connecting cover 600 through an elastic member, and the annular filter 6005 is fixed between the first connecting ring 6002 and the second connecting ring 6003.

[0044] An annular tube 500 is fixedly connected to the upper portion of the frame 100, and a plurality of groups of absorption tubes 5001 are fixedly connected to the annular tube 500, and the absorption tubes 5001 correspond to the screen frame. Specifically, the absorption tubes 5001 extend into the screen frame from one end of the annular tube 500, and an output tube 5002 is fixedly connected to the outside of the annular tube 500. By connecting a fan to the output tube 5002, a negative pressure can be formed inside the annular tube 500, and the remaining walnut particles accumulated on the annular filter 6005 that have not been screened can be sucked away. After being absorbed by the absorption tube 5001, they are sucked away by the dust suction fan, which facilitates the continued use of the subsequent screening components and avoids blockage of the screen frame.

[0045] When the absorption tube 5001 is started, it can cooperate with the flapping piece to flap the screen frame, so that the particles stuck in the screen frame are loosened and sucked away by the absorption tube 5001.

[0046] In this embodiment, the stirring assembly includes: a plurality of stirring rods 9003 and a plurality of driving columns 900 , and the stirring rods 9003 and the driving columns 900 are arranged in a one-to-one correspondence.

[0047] The stirring rod 9003 is rotatably connected to the extraction cylinder 200, and a plurality of stirring blades 9005 are provided on the periphery of the stirring rod 9003. The lengths of the stirring blades 9005 can be set to different levels. Moreover, the length of the stirring blades 9005 is smaller than the interval between the driving column 900 and the stirring rod 9003, thereby ensuring that the stirring blades 9005 can rotate under the drive of the stirring rod 9003; the driving column 900 is provided corresponding to the stirring rod 9003 and is rotatably connected to the extraction cylinder 200, and the driving column 900 is transmission-connected to the reciprocating mechanism, and the driving column 900 and the stirring rod 9003 are respectively connected with mutually meshing gears 9004 for driving the stirring rod 9003 to rotate.

[0048] Among them, the reciprocating mechanism includes: a reciprocating rod, a reciprocating member and a guide rod 8003. The reciprocating rod is a reciprocating screw rod 800. The reciprocating member can be realized by an annular fixed plate 8002. The center of the fixed plate 8002 is embedded with a reciprocating nut 8001 connected to the reciprocating screw rod 800, so that the reciprocating member can automatically reverse direction after moving up and down into position on the reciprocating rod, thereby realizing up and down reciprocation.

[0049] Specifically, the reciprocating rod is connected to the bottom end of the rotating rod 700, wherein the reciprocating rod can be integrally formed with the rotating rod 700, or a thread is provided on the part of the rotating rod 700 located in the extraction cylinder 200, the reciprocating member is screwed onto the reciprocating rod, and the beating member is circumferentially spaced apart on the reciprocating member. The beating member is driven by the reciprocating member to beat the bottom of the screen frame at intervals.

[0050] The guide rod 8003 is arranged in parallel with the reciprocating rod in the extraction cylinder 200, and the reciprocating member is slidably sleeved on the guide rod 8003. The guide rod 8003 ensures that the reciprocating member does not rotate circumferentially during the up and down sliding process.

[0051] like Figure 9 、 10 As shown, the driving column 900 is driven to rotate by a reciprocating member. Specifically, a connecting plate 8004 is provided on the outer periphery of the reciprocating member corresponding to the driving column 900. A through hole is provided on the connecting plate 8004, and the through hole is sleeved on the outer periphery of the driving column 900. An inclined groove 9001 is spirally opened on the outer periphery of the driving column 900. A pin 9002 is rotatably connected in the through hole of the connecting plate 8004. The pin 9002 is matched and embedded in the inclined groove 9001. During the reciprocating motion of the fixed plate 8002, the connecting plate 8004 is also driven to reciprocate. The connecting plate 8004 drives the pin 9002 to continuously slide in the inclined groove 9001. The cooperation between the pin 9002 and the inclined groove 9001 drives the column to rotate. The column drives the stirring rod 9003 to rotate back and forth through the gear 9004, thereby accelerating the mixing of acetone water and walnut particles.

[0052] In this embodiment, the beating member includes: an oblique support rod 8005 and a beating rod 8006.

[0053] One end of the diagonal support rod 8005 is connected to the side of the reciprocating part close to the screen frame, and the other end extends obliquely toward the screen frame. The beating rod 8006 is arranged parallel to the bottom of the screen frame. The beating rod 8006 is connected to the end of the diagonal support rod 8005 away from the reciprocating part. The distal end of the diagonal support rod 8005 is inclined toward the outside, so that when the top beating rod 8006 contacts the screen frame, it can receive a component of force toward the outside to prevent the diagonal support rod 8005 from being subjected to excessive force. At the same time, the diagonal support rod 8005 is arranged to extend upward, which can lift the top beating rod 8006, thereby reducing the setting range of the thread on the reciprocating rod to prevent the reciprocating part thereon from being too close to the bottom of the screen frame.

[0054] Those skilled in the art fully understand the technical solution, and the method of using this embodiment is as follows: First, place the walnuts between the first grinding disc 300 and the first grinding bucket 3001, start the drive motor 1001, and pour acetone water into the extraction cylinder 200; The motor 1001 drives the rotating rod 700 to rotate, and the rotating rod 700 drives the reciprocating screw rod 800 to rotate. The rotating rod 700 synchronously drives the first grinding disc 300 and the second grinding disc 400 to rotate. The walnuts can be ground and crushed by the first grinding disc 300 and the first grinding bucket 3001. The crushed walnuts can fall between the second grinding disc 400 and the second grinding bucket 4001 under the guidance of the guide plate. The walnuts can be further ground by the grinding between the second grinding disc 400 and the second grinding bucket 4001. The walnuts ground by the second grinding disc 400 and the second grinding bucket 4001 fall onto the annular filter 6005. During the rotation of the reciprocating screw 800, the reciprocating member 8002 is driven to reciprocate up and down. During the reciprocating up and down movement of the reciprocating member 8002, the beating rod 8006 is driven to continuously hit the first connecting ring 6002 and the second connecting ring 6003. The first connecting ring 6002 and the second connecting ring 6003 continuously compress the spring 6004, thereby generating vibration, which causes the annular filter 6005 to vibrate and achieve screening. The screened walnut particles fall into the extraction cylinder 200 and are finally mixed with the acetone water in the extraction cylinder 200. During the reciprocating motion of the reciprocating member 8002, the connecting plate 8004 is also driven to reciprocate, and the connecting plate 8004 drives the pin shaft 9002 to continuously slide in the inclined groove 9001. The cooperation between the pin shaft 9002 and the inclined groove 9001 drives the driving column 900 to rotate, and the driving column 900 drives the stirring rod 9003 to rotate back and forth through the gear 9004, thereby accelerating the mixing of acetone water and walnut particles; the acetone water is used to extract the residual emamectin in the pulp, and finally it is tested; after sufficient mixing, it can be discharged through the discharge pipe.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
