Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture, and more particularly to a convection type aquatic feed mixing device. Background Art

[0002] Aquatic feed mixing equipment is mainly used to mix the raw materials of aquatic feed according to scientific formulas to obtain aquatic feed with stable quality and constant characteristics. This type of equipment usually includes single-shaft mixers, double-shaft mixers, grate mixers, rotary mixers, etc.

[0003] Among them, the single-shaft double-screw ribbon mixer is a type of aquatic feed mixing equipment. It is mainly composed of a machine body, a rotor with double spiral ribbons welded on it, a power transmission part, a discharge device and a liquid spraying device. The spiral ribbon is divided into two inner and outer circles with opposite rotation directions. Under the push of the ribbon-shaped spiral blades, the outer spiral ribbon pushes the material from one end to the other, and the inner spiral ribbon makes the material move in the opposite direction. In the convection process, the two streams of material penetrate and mix with each other, and are mixed again in the tumbling process on both sides. This is repeated many times, and finally the mixed material is discharged from the discharge door through the discharge device.

[0004] However, the above-mentioned mixers and mixers still have the problem of uneven and insufficient mixing during the mixing process of aquatic feed. For mixing with aquatic feed, different types of raw materials are mostly mixed evenly, wherein the raw materials are of two types: liquid and solid, and the solids are in the form of blocks, granules and powders. The blocks and granules need to be crushed into powders and mixed with liquid raw materials during the mixing and stirring process. The powdered raw materials are easy to coagulate into blocks when mixed with liquid raw materials or water. When the raw materials are mixed, most of the liquid raw materials will adhere to the outer ends of the feed blocks or particles, thereby making the nutrient distribution of the mixed feed uneven, resulting in inconsistent growth of aquatic organisms when feeding aquatic organisms.

[0005] Therefore, in view of the above technical problems, it is necessary to provide a convection type aquatic feed mixing equipment. Summary of the invention

[0011] As a further improvement of the present invention, the material lifting assembly also includes a return spring, the return spring is wound around the outer end of the telescopic strip, and the return spring is fixedly connected between the mounting block and the accommodating plate.

[0012] As a further improvement of the present invention, the extension length of the telescopic strip is smaller than the depth of the groove, and the telescopic strip is made of a high-toughness deformable material.

[0013] As a further improvement of the present invention, the feed cylinder is composed of a plurality of storage boxes, a feed port is provided at one end of the feed cylinder close to the hydraulic rod, a rubber baffle is provided at the feed port, and an air duct is fixedly connected to the lower end of the drive motor.

[0014] As a further improvement of the present invention, a discharge trough is provided on the lower inner wall of the mixing barrel, and the discharge trough is located in the middle of the multiple turning components, an electric push rod is fixedly connected to the inner end of the discharge trough, a filling block is fixedly connected to the upper end of the electric push rod, a pair of discharge holes is provided at the lower end of the mixing barrel, and the discharge holes are connected to the discharge trough, and a collecting port is provided at the lower end of the support seat, and the collecting port is connected to the discharge holes.

[0017] Compared with the prior art, the advantages of the present invention are: (1) This solution includes a rolling column, a drive motor, a hydraulic rod, a stirring rod and a lifting assembly, which work together to ensure that the raw materials can be fully stirred and mixed. The rolling column rotates under the joint drive of the drive motor and the hydraulic rod, which not only helps the stirring rod and the lifting assembly to efficiently stir the powdered or granular raw materials, but also crushes the block feed through the physical action of the rolling column, thereby enhancing the homogeneity of the feed.

[0018] (2) The design of the rolling column in this scheme enables it to effectively crush the lumpy feed at the bottom during rotation. At the same time, a special turning component is designed at the bottom, which can effectively turn the bottom layer of feed to ensure the uniform distribution of the feed inside the mixing tank. In addition, the combination of the rotation of the rolling column and the operation of the turning component effectively reduces the formation of material piles and optimizes the mixing process.

[0019] (3) In this solution, the equipment also uses electromagnetic plate technology, which generates a magnetic field to repel magnetic blocks. These magnetic blocks are connected to the top block. When the electromagnetic plate is activated, the magnetic force it generates pushes the top block upward, thereby driving the bottom feed to turn over. This unique mechanism enhances the air flow and material redistribution within the feed, helping to improve mixing uniformity.

[0020] (4) In order to further improve the efficiency of feed turning and mixing, the equipment also includes a lifting component, which enhances the turning effect with the assistance of the rolling column and the electromagnetic plate. The lifting component automatically unfolds through the action of the torsion spring, driving the feed at the bottom upward, strengthening the turning of the feed and the contact with the air, and promoting more thorough mixing.

[0021] (5) In this solution, after the electromagnetic plate is magnetized, the equipment can attract the magnetic sheet, so that the containing plate can be separated and unfolded in the shrinking groove. This process not only simplifies the operation, but also makes the lifting plate unfold more effectively, further enhancing the effect of feed turning. This multifunctional integrated design not only improves the mixing efficiency, but also ensures the uniformity and quality of the feed. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Embodiment 1:

[0026] See also Figure 1-5 A convection-type aquatic feed mixing equipment comprises a mixing drum 1, a plurality of material turning components 8 and a plurality of material lifting components 9. The lower end of the mixing drum 1 is fixedly connected to a support seat 2, the upper end of the mixing drum 1 is fixedly connected to a feeding drum 3, the upper end of the feeding drum 3 is fixedly connected to a driving motor 4, the lower end of the driving motor 4 is fixedly connected to a hydraulic rod 5, the lower end of the hydraulic rod 5 is fixedly connected to a rolling column 6, and the outer end of the rolling column 6 is fixedly connected to a plurality of stirring rods 7. Various raw materials are put into the mixing drum 1 through the feeding drum 3, and the hydraulic rod 5 and the rolling column 6 are rotated under the drive of the driving motor 4, and the plurality of stirring rods 7 are rotated together for stirring. At the same time, the various raw materials are driven to turn under the extension and retraction of the hydraulic rod 5, so as to make the feed mixing more uniform.

[0027] The drive motor 4 and the hydraulic rod 5 are combined with the existing technology, similar to a telescopic stirring arm. Such equipment usually has a telescopic stirring arm, and its length can be automatically or manually adjusted according to the size of the container, while being able to stir.

[0028] A plurality of material turning components 8 are arranged on the lower inner wall of the mixing drum 1, and the material turning components 8 include a trapezoidal groove 81, which is opened on the lower inner wall of the mixing drum 1, and a top block 82 is slidably connected in the trapezoidal groove 81, and a magnetic block 83 is fixedly connected to the lower end of the top block 82. An electromagnetic plate 84 is inlaid on the lower inner wall of the mixing drum 1, and a plurality of magnetic blocks 83 are abutted against the electromagnetic plate 84. The electromagnetic plate 84 is activated and magnetized to repel the magnetic block 83, so that the top block 82 is lifted up and protruded, thereby turning over the feed gathered at the bottom.

[0029] A tough membrane is fixedly connected to the inner wall of the trapezoidal groove 81, and the tough membrane is made of a material with good wear resistance and high elasticity. The tough membrane can prevent feed from penetrating into the trapezoidal groove 81, and the tough membrane can be made of natural rubber, polyurethane, silicone, styrene-butadiene rubber, thermoplastic elastomer, polyamide; natural rubber has good wear resistance and is often used in the manufacture of tires, conveyor belts, etc. Natural rubber has very good elasticity and can withstand large deformations and return to its original state; polyurethane is a highly wear-resistant synthetic material and is widely used in high-wear environments, such as tires, soles, industrial rollers, etc. Polyurethane has excellent elasticity and can maintain its shape and performance under extreme conditions; silicone has good wear resistance and environmental aging resistance Chemical resistance, suitable for long-term use, silicone has excellent elasticity, and is often used in seals and gaskets in medical devices and the food industry; styrene-butadiene rubber has strong wear resistance and is commonly found in automobile tires and industrial tapes. Styrene-butadiene rubber also has good elasticity, especially its performance is better than natural rubber in low temperature environments; thermoplastic elastomers combine the ease of processing of plastics with the elastic properties of rubber, and have good wear resistance. TPE has high elasticity similar to rubber and can maintain its performance after multiple processing; polyamide, commonly known as nylon, is a very wear-resistant material and is widely used in tires and other products that require high wear resistance. Although nylon is not as elastic as the above-mentioned rubber materials, it exhibits good toughness and flexibility when subjected to impact and mechanical stress.

[0030] A plurality of grooves are provided at the lower end of the rolling column 6, and a plurality of lifting components 9 are fixedly connected in the grooves. A sealing ring may be provided at the opening of the groove, and the sealing ring fits with the lifting component 9. The sealing ring can be used to wipe off the feed fragments adhering to the outer end of the lifting component 9 to prevent it from getting stuck in the groove. The lifting component 9 includes a mounting block 91, which is fixedly connected to the inner end of the groove. A telescopic strip 92 is fixedly connected to the lower end of the mounting block 91, and a receiving plate 93 is fixedly connected to the lower end of the telescopic strip 92. A plurality of rotating grooves are provided at the outer end of the receiving plate 93, and a lifting plate 94 is rotatably connected in the rotating groove, and the lifting plate 94 is rotatably connected to the rotating groove by a torsion spring. An anti-sticking film is fixedly connected to the inner end of the rotating groove, and the anti-sticking film can be used to reduce the lifting plate 94 and the rotating groove. There are feed crumbs mixed in the trough, and the anti-sticking film has toughness and can be pressed against the inner wall of the rotating trough. When the lifting plate 94 is unfolded, the anti-sticking film is reset and tightened to eject or slide the feed crumbs, thereby greatly reducing the inclusion of feed crumbs. A magnetic suction sheet 95 is fixedly connected to the lower end of the receiving plate 93, and is activated and magnetized by the electromagnetic plate 84. The electromagnetic plate 84 is connected to a strong current to make its magnetism stronger. Therefore, while pushing the top block 82 to bulge, it also attracts the magnetic suction sheet 95, so that the receiving plate 93 pulls the telescopic strips 92 and 96, and the receiving plate 93 is separated from the groove, exposing the lifting plate 94. Under the action of the torsion spring, multiple lifting plates 94 are unfolded to lift the feed when the hydraulic rod 5 is extended and retracted, so as to disperse and stir various raw materials, thereby making the feed mixed more evenly.

[0031] The lifting assembly 9 also includes a return spring 96, which is wound around the outer end of the telescopic strip 92. The return spring 96 is fixedly connected between the mounting block 91 and the receiving plate 93. The elastic force of the return spring 96 assists the receiving plate 93 to return to the groove.

[0032] The extension length of the telescopic strip 92 is less than the depth of the groove, and the telescopic strip 92 is made of a high-toughness deformable material. By limiting the length, the accommodating plate 93 can be prevented from being separated from the groove and difficult to reset. The telescopic strip 92 can be made of silicone rubber material, which has elasticity and can play a resetting role. When the lifting plate 94 is recovered to the rotating groove, it uses the pulling force of the telescopic strip 92 and the reset spring 96 respectively to overcome the torsion spring force after losing the magnetic attraction, and is recovered into the rotating groove after the lifting plate 94 is squeezed with the groove wall.

[0033] The feeding barrel 3 is composed of a plurality of material storage boxes. A feeding port is provided at one end of the feeding barrel 3 close to the hydraulic rod 5. The feeding port is provided with a rubber baffle. An air duct is fixedly connected to the lower end of the driving motor 4. The rubber baffle is used to block the feeding port to prevent excessive leakage of raw materials. The air duct can be used to conduct the heat of the driving motor 4 to the mixing barrel 1 to dry the feed, which is convenient for subsequent storage.

[0034] A discharge trough 10 is provided on the lower inner wall of the mixing barrel 1, and the discharge trough 10 is located in the middle of the multiple turning components 8. An electric push rod 11 is fixedly connected to the inner end of the discharge trough 10, and a filling block 12 is fixedly connected to the upper end of the electric push rod 11. A pair of discharge holes 13 are provided at the lower end of the mixing barrel 1, and the discharge holes 13 are connected to the discharge trough 10. A collecting port 14 is provided at the lower end of the support seat 2, and the collecting port 14 is connected to the discharge holes 13. The filling block 12 is pulled by the electric push rod 11 to break away from the seal on the top of the discharge trough 10, so that the mixed feed enters the discharge trough 10 and flows from the discharge holes 13 to the collecting port 14 for discharge.

[0035] A telescopic rod 15 is fixedly connected to the inner end of the feeding barrel 3, and a push plate 16 is fixedly connected to the end of the telescopic rod 15 away from the hydraulic rod 5. The push plate 16 is made of magnetic material. A magnetic plate 17 is fixedly connected to the outer end of the hydraulic rod 5 close to the rolling column 6. The hydraulic rod 5 moves up and down, so that the magnetic plate 17 floats up and down in the middle of the feeding barrel 3. When the magnetic force of the magnetic plate 17 is utilized to move it to the middle of the feeding barrel 3, the push plate 16 is attracted, so that the raw material is pushed to the feed port, squeezed out of the baffle and entered into the mixing barrel 1, so as to achieve the purpose of automatic filling.

[0036] An auxiliary plate 18 is fixedly connected to the outer wall of the upper end of the rolling column 6, and the upper end surface of the auxiliary plate 18 is in the shape of an arc. Raw materials are relatively fed through multiple feeding ports of the feeding barrel 3, so that various raw materials fall to the upper end of the auxiliary plate 18. When the hydraulic rod 5 rotates, the auxiliary plate 18 is driven, and the centrifugal force is used to evenly disperse the raw materials on the upper end of the auxiliary plate 18, thereby effectively improving the mixing uniformity of the feed.

[0037] Working principle: A variety of raw materials are put into the mixing barrel 1 through the feeding barrel 3. When put in, due to the relative discharge of multiple feeding ports, the raw materials are mixed with each other, and the various raw materials fall to the upper end of the auxiliary plate 18. The hydraulic rod 5 and the rolling column 6 are driven by the driving motor 4 to rotate. The auxiliary plate 18 is driven by the rotation of the hydraulic rod 5, and the raw materials on the upper end of the auxiliary plate 18 are evenly dispersed and scattered by centrifugal force, and multiple stirring rods 7 are rotated together for stirring. At the same time, under the extension and retraction of the hydraulic rod 5, the various raw materials are driven to turn over slightly, and the magnetization is activated by the electromagnetic plate 84 to repel the magnetic block 83, so that the top block 82 is raised and protruded, so as to turn over the feed gathered at the bottom, and the magnetization is activated by the electromagnetic plate 84 to attract the magnetic suction sheet 95 at the same time, so that the containing plate 93 is pulled The telescopic bars 92 and 96 disengage the containing plate 93 from the groove, exposing the lifting plate 94. Under the action of the torsion spring, multiple lifting plates 94 are unfolded to lift the feed when the hydraulic rod 5 is extended and retracted, so as to disperse and stir the various raw materials, so as to make the feed mixed more evenly. The hydraulic rod 5 moves up and down, so that the magnetic plate 17 floats up and down in the middle of the feeding barrel 3. When the magnetic force of the magnetic plate 17 is used to move it to the middle of the feeding barrel 3, the pushing plate 16 is attracted, so that the raw materials are pushed to the feed inlet, squeezed out of the baffle bar and entered into the mixing barrel 1, so as to achieve the purpose of automatic filling. Subsequently, the filling block 12 is pulled by the electric push rod 11 to disengage the seal on the top of the discharge trough 10, so that the mixed feed enters the discharge trough 10 and flows from the discharge hole 13 to the collection port 14 for discharge.

[0038] It can be seen from the above technical solutions that the present invention has the following beneficial effects: In this scheme, the purpose of fully stirring and mixing the raw materials is achieved by the rolling column 6, which is driven by the driving motor 4 and the hydraulic rod 5 to make the stirring rod 7 and the lifting assembly 9. While the rolling column 6 rotates and stirs, the block feed is crushed by its bottom, and the bottom feed is turned by the turning assembly 8. The electromagnetic plate 84 repels the magnetic block 83, so that the multiple top blocks 82 are lifted up, so that the bottom feed is lifted up and turned over. At the same time, under the passive condition of the lifting assembly 9, the feed can be turned over assisted. The electromagnetic plate 84 activates the magnetism and attracts the magnetic suction sheet 95, so that the containing plate 93 is separated from the contraction groove. Under the action of the torsion spring, the lifting plate 94 is unfolded to drive the bottom feed to lift and turn it, thereby reducing the accumulation of the bottom feed, thereby effectively improving the efficiency of feed mixing and achieving uniform and sufficient mixing.
