Description

Technical Field

[0001] The invention relates to the technical field of agricultural product processing pretreatment equipment, in particular to a peanut particle stir-frying and peeling machine for peanut oil pressing. Background Art

[0002] Peanut oil is a widely promoted edible oil that is easy to digest. The production of peanut oil first requires pretreatment of the raw materials. Pretreatment includes: (1) Cleaning and screening: Clean mud and impurities, and remove imperfect grains such as those that are moldy, worm-eaten, etc.

[0003] (2) Shelling: Use a shelling machine to shell the peanut kernels. The shelled peanut kernels need to be screened again to ensure that no shells remain.

[0004] (3) Peeling: Use a peeling machine to remove the outer skin of the peanut kernel (red skin). Because the peanut skin contains natural pigments, if it is not removed, the extracted oil may be darker in color. Removing the peanut skin can make the extracted peanut oil clearer in color, reduce possible bitterness, and reduce impurities in the oil.

[0005] (4) Stir-frying: Stir-frying the peanuts in a stir-fry machine can enhance the aroma of the peanuts; it also helps to destroy the cell structure of the peanuts, making it easier for the oil to be released.

[0006] (5) Crushing: The roasted peanuts are sent to a crusher for crushing to further destroy the peanut cell structure so that the oil can be extracted more effectively in the subsequent pressing process.

[0007] The above process is also interspersed with drying. The moisture in the peanuts is removed by natural drying or equipment drying to improve the oil extraction efficiency and prevent mildew during storage and processing. After that, the actual oil extraction process such as pressing, filtering, and refining is carried out.

[0008] In the above process, for example, stir-frying. In enterprises, stir-frying is mostly carried out in large-capacity mixing tanks and stir-fry pans. A stirring structure is set in the container to stir and stir the peanuts, so that the peanuts are heated evenly as much as possible to avoid being burnt. Traditional stirring structures are mostly stirring paddle structures, that is, a number of branches are evenly distributed on the shaft, and the peanuts are stirred through the branches as the shaft rotates; or eccentric plate structures, with a tilted plate structure set at the bottom of the shaft. During the stirring process, the peanuts at the bottom are stirred through the plate to prevent the peanuts at the bottom from always being in contact with the heat source and becoming burnt.

[0009] The above-mentioned types of stir-frying and stirring mechanisms have limitations when used: when stir-frying and stirring, the position changes of the upper and lower layers of peanuts and the inner and outer layers of peanuts are always uneven, that is, the outer layer and the bottom layer are always heated stronger than the inner layer and the upper layer, resulting in uneven frying, resulting in some peanuts being cooked or even burnt when the stir-frying time is reached, while some may not be cooked yet.

[0010] Moreover, in traditional processes, frying and peeling are mostly performed separately, which is not only more complicated in terms of procedures, but also requires setting up two production lines, or performing them one by one on the same production line. This requires two sets of corresponding process equipment: stir-frying machines, peeling machines, etc., which increases production costs.

[0011] To this end, the present invention provides a peanut particle stir-frying and peeling machine for peanut oil pressing, which combines the stir-frying and peeling processes, thereby saving equipment costs and improving the efficiency and effect of peanut pretreatment.

[0022] Compared with the prior art, the present invention provides a peanut granule stir-frying and peeling machine for peanut oil extraction, which has the following beneficial effects: 1. The present invention drives the gathering fan to rotate counterclockwise through a driving structure, stirs and stirs while gathering materials in the direction of the auger, and transports them upward through the auger to achieve the exchange between the upper and lower layers of peanuts in the stir-fry pan. The peanuts are gathered from the outside to the inside by the gathering fan and transported from the bottom to the top by the auger, so that the heating of the peanuts inside and outside and above the peanuts in the stir-fry pan is more balanced to reduce the probability of burnt peanuts.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0049] Embodiment 1, in order to solve the problems of uneven distribution of heat and dispersed frying and peeling of peanuts in the frying and peeling pretreatment process of peanuts in the prior art, this embodiment provides a peanut frying and peeling machine for peanut oil extraction, comprising: A stir-fry pan 4 and a matching pot cover 5, wherein the pot cover 5 is provided with a feeding port 6; A conveying cylinder 7 is provided in the frying pan 4, and an auger 9 is provided in the conveying cylinder 7. The auger 9 is driven by a driving structure 13 arranged on the pot cover 5 and can be reversed. A feeding pipe 10 is provided at the lower end of the conveying cylinder 7 to pass through the frying pan 4. The conveying cylinder 7 is located at the inner bottom wall of the frying pan 4 and is provided with multiple feeding ports 8 around it. A plurality of guide hoppers 11 with trapezoidal cross-sections are vertically spaced at intervals on the outer wall of the upper end of the conveying cylinder 7. Peeling disks 20 are rotatably installed on the end faces on the opposite side of the upper end faces of the plurality of guide hoppers 11. The two peeling disks 20 on the opposite sides of two adjacent guide hoppers 11 are driven by a reciprocating mechanism to reciprocate and deflect in opposite directions; a gathering fan 14 is rotatably installed on the outer wall of the lower end of the conveying cylinder 7. The gathering fan 14 is connected to the output end of the driving structure 13 via a transmission structure. Through the transmission structure, the gathering fan 14 always rotates in one direction to gather peanuts toward the feeding port 8 of the conveying cylinder 7 regardless of the forward and reverse rotation of the auger 9.

[0050] Principle details of this embodiment: A peanut granule stir-frying and peeling machine for peanut oil extraction, comprising: (1) Base 1. The base 1 is a table structure, serving as the installation foundation of the entire device and providing an installation and support reference surface.

[0051] (2) A stir-fry pan 4 and a matching pot cover 5. The upper end surface of the base 1 is provided with three groups of columns 3 in a circular array, and a support ring is embedded in the upper ends of the three columns 3, and the stir-fry pan 4 is embedded in the inner circle of the support ring. The stir-fry pan 4 and the pot cover 5 can be locked to prevent the pot cover 5 from exploding and peanuts from splashing during the stir-frying process. The pot cover 5 is provided with a feeding port 6 for directly feeding peanuts without opening the cover, making feeding more convenient. The feeding port 6 is equipped with a sealing cover, which is closed when not feeding, so as to prevent the peanuts from being scattered to the outside and reduce the dissipation of heat energy.

[0052] (3) The heating device 2 is used to heat the peanuts in the stir-fry pan 4.

[0053] The heating device 2 has a variety of options, and can be an induction cooker structure (electric induction heating), an electric heating plate structure (multiple groups of electric heating plates or electric heating wires are densely arranged on the inner wall of the stir-fry pot 4, and an external power supply is connected to generate heat by powering on), an open flame heating device (an external stove, gas ignition directly burns the bottom wall of the stir-fry pot 4), or an external heating medium circulation structure (a spiral tube is set on the outer wall of the stir-fry pot 4, and a liquid heat-conducting medium such as hot water and hot oil circulates in the tube; the air inlet and outlet pipes are set inside the stir-fry pot 4, and dry hot air is circulated from top to bottom or from bottom to top).

[0054] In the drawings of the present embodiment, an electromagnetic cooker heating structure is selected, which uses the electromagnetic induction principle to achieve heating. In the drawings of the present embodiment, the specific structure of the electromagnetic cooker heating structure includes but is not limited to: a heat-resistant ceramic plate arranged at the upper end of the base 1, a coil below the heat-resistant ceramic plate, a high-strength, impact-resistant ceramic flat plate (crystallized glass) on the table top of the base 1, a high-frequency induction heating coil (i.e., an excitation coil), a high-frequency power conversion device and a corresponding control system, a control panel on the front side of the base 1, and a fan for dissipating heat from the above components in the base 1 are installed under the table top. The stir-fry pan 4 is a metal pot body with high magnetic permeability such as an iron pot or a stainless steel pot. When in use, the alternating current is converted into direct current through a rectifier, and the direct current is converted into high-frequency alternating current exceeding the audio frequency through a high-frequency power conversion device, and the high-frequency alternating current is applied to the flat hollow spiral induction heating coil, thereby generating a high-frequency alternating magnetic field, and its magnetic lines of force penetrate the ceramic table and act on the metal stir-fry pan 4. That is, an alternating magnetic field with a constantly changing direction is generated by passing an alternating current through a coil. A strong eddy current is generated inside the conductor (the stir-fry pan 4) in the alternating magnetic field due to electromagnetic induction (the reason can be referred to Faraday's law of electromagnetic induction). When the eddy current overcomes the internal resistance of the stir-fry pan 4 and flows, the conversion of electrical energy into thermal energy is completed, i.e., Joule heat. The Joule heat effect of the eddy current heats up the conductor, thereby achieving heating, which acts on the peanuts in the stir-fry pan 4, i.e., frying and heating.

[0055] A conveying cylinder 7 is provided at the axis of the stir-fry pot 4, and the conveying cylinder 7 is fastened in the stir-fry pot 4 by the cooperation of a flange and bolts, or is welded and fixed in the stir-fry pot 4. The lower end of the conveying cylinder 7 is located at the outer wall that fits the inner bottom wall of the stir-fry pot 4, and a plurality of feeding ports 8 are arranged in a circular array, which are used as channels for conveying peanuts into the conveying cylinder 7. An auger 9 is provided in the conveying cylinder 7, and the auger 9 is driven by a driving structure 13 provided on the pot cover 5 and can rotate forward and reverse.

[0056] The bottom axis of the stir-fry pan 4 is provided with a feed pipe 10 that penetrates the bottom wall of the stir-fry pan 4, and the upper end of the feed pipe 10 is connected to the conveying cylinder 7. The table top of the base 1 is also provided with a through hole, which is located at the center of the coil and does not affect the layout of the coil. The lower end of the feed pipe 10 passes through the through hole and is located below the coil and corresponding components, and passes out from the side of the base 1.

[0057] The outer wall of the upper end of the conveying cylinder 7 is vertically spaced apart with a plurality of guide hoppers 11, the cross section of the guide hoppers 11 is trapezoidal, and a plurality of material discharge channels are formed by the plurality of guide hoppers 11, which are used to receive and divert the peanuts conveyed by the auger 9. The spacing between two connected guide hoppers 11 is not less than the belly diameter of the peanuts. Preferably, an auxiliary rod can be provided between the outer edge of each guide hopper 11 and the inner wall of the stir-fry pot 4, which is used to assist in supporting the material and indirectly acts on the upper end surface of the conveying cylinder 7, so that the auger 9 arranged inside is installed more stably.

[0058] Among the multiple guide hoppers 11, the plane parts of the opposite sides of two adjacent guide hoppers 11 are provided with a rotating groove, and a peeling disc 20 is rotatably installed in the rotating groove. The friction surface of the peeling disc 20 is provided with a rubber friction pad, which can enhance the friction force and improve the peeling effect; and can avoid the hard structure from contacting the peanuts and directly crushing the peanuts. The two peeling discs 20 on the opposite sides of the two adjacent guide hoppers 11 are driven by the same set of reciprocating mechanisms to reciprocate and deflect in opposite directions.

[0059] The outer wall of the lower end of the conveying cylinder 7 is rotatably mounted with a gathering fan 14, which is connected to the output end of the driving structure 13 via a transmission structure. The gathering fan 14 is driven by the transmission structure to rotate in one direction to gather peanuts toward the feeding port 8 of the conveying cylinder 7 regardless of the forward and reverse rotation of the auger 9. Fig.10 As shown, the material gathering fan 14 includes two fan rings of different diameters and arranged concentrically, and a plurality of fan blades are arranged between the two fan rings. The small diameter fan ring is rotatably mounted on the outer wall of the conveying cylinder 7, and the rotatable mounting part is located above the feed inlet 8; the outer wall of the large diameter fan ring is attached to the inner wall of the stir-fry pan 4. The bottom wall of the fan blade is attached to the inner bottom wall of the stir-fry pan 4 and presents an arc state.

[0060] In this embodiment, the driving structure 13 includes a gear box arranged on the pot cover 5. A rotating shaft 41 is installed in the gear box for horizontal rotation. The rotating shaft 41 is coaxially arranged with the auger 9, and the lower end of the rotating shaft 41 extends from the bottom wall of the gear box; a worm wheel is integrally rotated on the rotating shaft 41, and the worm wheel is meshed with a worm rotatably installed in the gear box. The shaft end of the worm extends from the side wall of the gear box, and the shaft end of the worm extending from the gear box is connected to the motor fixed on the pot cover 5 through a coupling or a chain drive. The motor is a type of motor that can realize forward and reverse rotation. A mounting hole is provided on the pot cover 5, and a rotating seat is provided in the mounting hole. The lower end of the rotating shaft 41 is rotatably installed in the mounting hole through a bearing, which is used to provide auxiliary support for the rotating shaft 41.

[0061] In this embodiment, the reciprocating mechanism includes a front shaft 15 and a plurality of crankshafts 16: the front shaft 15 is located at the top and is directly connected to the rotating shaft 41 through a connecting tube; among the plurality of crankshafts 16, the bottom crankshaft 16 is directly connected to the upper shaft end of the auger 9; the remaining crankshafts 16 are either rotatably mounted from bottom to top on the axial position of a horizontal part of a guide hopper 11 (except for the top and bottom guide hoppers 11, the axes of the remaining guide hoppers 11 are all provided with hanging plates as a bearing base, and the hanging plates are provided with through holes for peanuts to pass through), or suspended; the front shaft 15 and all crankshafts 16 are coaxially arranged. The opposite surfaces of the front shaft 15 and the top crankshaft 16 and the opposite surfaces of the two adjacent crankshafts 16 are integrally rotatably mounted with cranks 17, and the ends of the two adjacent cranks 17 are rotatably connected with a neck shaft 18. Two connecting rods 19 are axially and rotatably installed on each neck shaft 18. The ends of the two connecting rods 19 are rotatably connected to connecting shafts. The two connecting shafts are respectively rotatably installed on the peeling disks 20 on the opposite sides of the two adjacent guide hoppers 11, and the two connecting shafts are radially symmetrically arranged along the peeling disks 20.

[0062] In this embodiment, the connection structure includes a mounting tube 27 rotatably mounted on the upper end surface of the horizontal part of the uppermost material guide hopper 11, and the upper end of the mounting tube 27 is rotatably matched with a top cover, and a plurality of connecting columns are provided between the top cover and the outer wall of the uppermost material guide hopper 11, so as to fix the top cover, and the mounting tube 27 is sealed by the top cover to prevent peanuts from falling into the mounting tube 27; and a cone bucket is provided on the top cover to prevent peanuts from falling and being retained on the top cover. The inner wall of the installation cylinder 27 is provided with a driven gear 26 that rotates integrally. The driven gear 26 is meshed with a turning gear 1 24 that is rotatably mounted on the outer wall of the top material guide hopper 11. The turning gear 1 24 is meshed with a turning gear 25 that is rotatably mounted on the outer wall of the top material guide hopper 11. The turning gear 25 is not meshed with the driven gear 26. The output end of the driving structure 13, that is, the rotating shaft 41, is provided with a driving gear 22 that rotates integrally. The driving gear 22 is meshed with a moving gear 23 that cooperates with the turning gear 1 24 and the turning gear 25. The moving gear 23 is rotatably mounted on the slider 29. An arc-shaped slide groove 28 that is coaxially arranged with the driving gear 22 is provided on the top cover between the driving gear 22 and the turning gear 1 24 and the turning gear 25. The slider 29 is slidably mounted in the arc-shaped slide groove. A plurality of curved rods connected to the material gathering fan 14 are arranged in an annular array on the outer wall of the installation cylinder 27, so that the material gathering fan 14 is integrally rotatably connected with the installation cylinder 27 / driven gear 26. The driving gear 22, the moving gear 23, the steering gear 1 24, the steering gear 25, and the driven gear 26 are all helical gears, and the line contact characteristics of the helical gears when they are separated and contacted are used to avoid tooth collision during the meshing and separation of the moving gear 23 and the steering gear 1 24 and the steering gear 2 25.

[0063] According to the above technical solution: The first step: open the cover, put the peanuts into the stir-fry pan 4 through the feeding port 6, and then close the feeding port 6.

[0064] Step 2: Turn on the heating device 2 to heat the peanuts in the stir-fry pan 4.

[0065] Step 3: Start the motor, and the motor drives the shaft 41 to rotate counterclockwise through the worm gear structure. The shaft 41 first drives the driving gear 22 to rotate counterclockwise. Fig.14 As shown, the driving gear 22 rotates counterclockwise, which drives the moving gear 23 to rotate clockwise and offset counterclockwise, so that the moving gear 23 meshes with the second steering gear 25 and drives the second steering gear 25 to rotate counterclockwise; the second steering gear 25 drives the first steering gear 24 to rotate clockwise, and the first steering gear 24 drives the driven gear 26 to rotate clockwise, thereby driving the installation cylinder 27 to rotate clockwise, and the driven gear drives the gathering fan 14 to rotate clockwise. Fig.10As shown, while the gathering fan 14 rotates counterclockwise, it stirs the peanuts conventionally and stirs them; at the same time, it relies on its own structural shape to cause the peanuts to gather toward the feeding port 8 of the conveying cylinder 7 in the center of the stir-fry pan 4, and the peanuts enter the interior of the conveying cylinder 7 through the feeding port 8.

[0066] When the rotating shaft 41 rotates counterclockwise, it drives the auger 9 to rotate counterclockwise through the front shaft 15, the crankshaft 16, the neck shaft 18 and other connection transmission cooperation. During the counterclockwise rotation of the auger 9, the peanuts are transported upward by the auger 9 to the multiple guide hoppers 11, and the peanuts first fall between two opposing peeling discs 20. The two peeling discs 20 are both rotatably connected to the connecting rods 19 on the opposite surfaces through the connecting shaft, and the two connecting rods 19 are rotatably mounted on the same neck shaft 18. As the rotating shaft 41 rotates counterclockwise, the front shaft 15 and the crankshaft 16 drive the crank 17 to rotate counterclockwise, and cooperate with the connecting rod 19 and the connecting shaft to form a crank 17 slider 29 mechanism. During the rotation of the crank 17, the peeling disc 20 is driven to deflect through the connecting rod 19; because the two connecting rods 19 are symmetrically arranged, when the connecting rod 19 is driven, the two opposing peeling discs 20 rotate in opposite directions and staggered, forming a reciprocating kneading process. At the beginning of frying, it is not easy to rub off the peanut skins because there is still moisture inside the peanuts. As the frying process continues, the peanuts are gradually cooked and the peanut skins gradually change from wet to dry. The dry peanut skins can be easily separated from the peanut kernels by rubbing, thus completing the peeling process.

[0067] The peanuts rubbed by the peeling plate 20 are squeezed by the continuously conveyed peanuts and move away from the peeling plate 20, gradually fall into the inclined portion of the guide hopper 11, and fall into the stir-fry pan 4 again along the inclined portion.

[0068] Through the above process, the driving structure 13 drives the gathering fan 14 to rotate counterclockwise, stir and fry while gathering materials toward the auger 9, and transporting them upward through the auger 9 to achieve the exchange between the upper and lower layers of peanuts in the stir-fry pot 4. The peanuts are gathered from the outside to the inside by the gathering fan 14 and transported from the bottom to the top by the auger 9, so that the heating of the peanuts inside and outside and above the peanuts in the stir-fry pot 4 is more balanced to reduce the probability of burning. In the process of conveying the peanuts up and down, the reciprocating rubbing of the peeling plate 20 promotes the molting of the peanut skin, so that the stir-frying and peeling of the peanuts are integrated, which can speed up the pretreatment of the peanuts and improve the efficiency; and save the equipment component cost of the double-line or single-line double equipment.

[0069] After the peanuts are fried, the peanuts need to be discharged. At this time, the drive structure 13 drives the rotating shaft 41 to rotate clockwise, and the rotating shaft 41 first drives the driving gear 22 to rotate counterclockwise. Fig.15As shown, the driving gear 22 rotates clockwise with the rotating shaft 41, which drives the moving gear 23 to rotate counterclockwise and deviate clockwise, so that the moving gear 23 meshes with the direction-adjusting gear 1 24 and drives the direction-adjusting gear 1 24 to rotate clockwise, thereby driving the mounting cylinder 27 to rotate clockwise, and the gathering fan 14 is driven to rotate clockwise. That is, the gathering fan 14 always keeps rotating clockwise, so that it is always in a state of gathering materials toward the auger 9.

[0070] When the main shaft rotates clockwise, the front shaft 15, the crankshaft 16, the neck shaft 18 and the like are connected and driven to drive the auger 9 to rotate clockwise. The auger 9 rotates clockwise, which drives the peanuts and the peeled peanut skins to be transported downward to the feeding pipe 10, so that the peanuts are discharged along the feeding pipe 10 to realize the feeding operation. The whole process reduces manual operation, has a higher degree of automation, and is easier and faster to operate.

[0071] In this embodiment, a hot air circulation component is also included, and the hot air circulation component includes a circulating air pump 34 arranged outside the stir-fry pot 4, and the air inlet of the circulating air pump 34 is connected to the air inlet pipe 35, and the air inlet pipe 35 is inserted into the stir-fry pot 4 from the pot cover 5; the air outlet of the circulating air pump 34 is connected to the air outlet pipe, and the air outlet pipe is connected to the feeding pipe 10. A valve is provided at the end of the feeding pipe 10. When stir-frying, the valve is closed, and the circulating air pump 34 extracts the hot air from the upper layer of the stir-fry pot 4, and then injects it into the feeding pipe 10, and floats up with the peanuts transported by the auger 9, or overflows from the feeding port 8. The extraction of the upper hot air of the frying pan 4 can not only make the hot air at the bottom of the frying pan 4 float up, thereby making the air temperature in the pan relatively balanced, but also use the floating hot air to assist the upper peanuts to be heated, so that the difference in heating temperature between the upper peanuts and the lower peanuts when they are still in the pan is reduced; and the hot air will float up in the conveying tube 7 or overflow from the feeding port 8, so that the peanuts in the conveying process are also heated, and the purpose of balanced heat generation of the peanuts inside and outside the conveying tube 7 is achieved. When unloading, the valve is opened, which does not affect the discharge of peanuts.

[0072] In this embodiment, an extension tube 21 is provided between the conveying cylinder 7 and the feeding tube 10. The extension tube 21 is bent at a right angle, and the lower end of the auger 9 is rotatably mounted on the bottom wall of the bending portion of the extension tube 21. The existence of the extension tube 21 provides a stable mounting base for the lower shaft end of the auger 9; and the auger 9 extends below the feed inlet 8, completely covering the upper and lower parts of the feed inlet 8, thereby preventing the peanuts from falling during the upward feeding process, and extending the optical axis length of the lower shaft section of the auger 9, thereby preventing the peanuts from being squeezed and blocked again.

[0073] In this embodiment, the outer edges of the plurality of guide hoppers 11 gradually move away from the axis of the stir-fry pan 4 from bottom to top, so that the peanuts are randomly scattered on the upper peanut surface, which is random. Alternatively, the outer edges of the plurality of guide hoppers 11 are all at the same vertical section, and the peanuts are scattered near the inner side wall of the stir-fry pan 4, thereby continuing the material conveying cycle from top to bottom and from outside to inside.

[0074] Embodiment 2, in a further embodiment of the present scheme, a plurality of dividing rods are densely distributed on the side walls on the opposite side of the plurality of guide hoppers 11, and the dividing rods are staggeredly arranged.

[0075] See attached Figure 8 , Attachment Fig.16 , Attachment Fig.17 As shown, the inclined surfaces on the opposite sides of two adjacent guide hoppers 11 are densely covered with a plurality of dividing rods, and the adjacent guide hoppers 11 are connected by the plurality of dividing rods. The plurality of dividing rods are staggered on the surface of the guide hopper 11, that is, the guide rods 12 are not arranged neatly along the generatrix direction of the guide hopper 11. Thus, the peanut particles falling into the guide hopper 11 fall randomly along the guide rods 12, so as to present the randomness of the scattered peanut particles, avoid the peanut particles falling on one side or more falling on one side, so that the peanut particles are evenly dispersed, so that the heating is balanced.

[0076] Embodiment 3, in a further embodiment of this scheme, if there is damage to the components of the conveying tube 7 in the stir-fry pan 4, the pot cover 5 needs to be removed. Conventional connection methods such as locks and bolts are troublesome to disassemble and assemble. Therefore, in this embodiment, a structure that is easier to open the pot cover 5 is provided: The pot cover 5 is symmetrically provided with two rotating seats around it, and the two rotating seats are respectively rotatably matched with the two uprights 3, so that the pot cover 5 is rotatably installed relative to the frying pan 4, and can be flipped back to open. Two sets of rocker arms 33 are symmetrically provided at the rear side of the pot cover 5, and a hydraulic rod 32 is rotatably installed on the base 1 just behind the axis of the frying pan 4, and the extended end of the hydraulic rod 32 is rotatably connected to the ends of the two rocker arms 33. In this way, the opening and closing of the pot cover 5 can be controlled by the extension and contraction of the hydraulic rod 32.

[0077] In this embodiment, in order to make the pot cover 5 more firmly locked in the closed state, a locking mechanism is provided between the upright column 3 that does not rotate with the pot cover 5 and the pot cover 5, so as to tightly seal the pot cover 5. Fig.13As shown, the locking structure includes an extension plate 37 arranged at the outer edge of the pot cover 5, and the extension plate 37 is symmetrically arranged with the hydraulic rod 32. A handle 38 is rotatably installed at the end of the extension plate 37, and an L-shaped hook 39 is provided at the rotation connection part of the handle 38. The horizontal end of the hook 39 is tilted upward, and the vertical end of the hook 39 is arranged vertically with the handle 38. The upper end of the column 3 that does not rotate with the pot cover 5 is open, and a stud is fixed inside the opening. A buckle seat embedded in the opening is screwed on the stud, and a hook handle 40 that cooperates with the hook 39 is provided on the buckle seat. When the pot cover 5 is closed, the handle 38 is screwed counterclockwise so that the hook 39 is hooked on the hook handle 40, so that the end of the pot cover 5 is buckled, thereby improving the closed stability of the pot cover 5.

[0078] In this embodiment, since the pot cover 5 is rotatably installed relative to the stir-fry pan 4, after the pot cover 5 is opened, the rotating shaft 41 of the driving structure 13 and the front end shaft 15 of the reciprocating mechanism cannot be fixedly connected, otherwise the opening of the pot cover 5 is interfered. Therefore, it is also necessary to set a structure that does not affect the turning of the pot cover 5 and can realize the connection and matching between the rotating shaft 41 and the front end shaft 15: the lower end of the rotating shaft 41 is fastened with an electromagnet with a heat-insulating shell by screws, and the shell is provided with a mounting sleeve, and a polygonal metal driving block 30 is vertically slidably installed in the mounting sleeve, and a spring is provided between the driving block 30 and the mounting sleeve. The upper end of the front end shaft 15 is provided with a polygonal connecting hole 31 that cooperates with the driving block 30, and the upper end of the connecting hole 31 is chamfered. By controlling the power off and power on of the electromagnet, the lifting and lowering of the driving block 30 can be controlled, and then the separation and connection of the rotating shaft 41 and the front end shaft 15 can be controlled. The rotating shaft 41 is a hollow shaft so that the circuit of the electromagnet passes through, and the circuit setting connection should adopt a rotating structure, so that the circuit of the electromagnet will be knotted due to the rotation of the rotating shaft 41. Or a ring-shaped electromagnet is adopted, the electromagnet is directly arranged on the inner wall of the pot cover 5 and is arranged coaxially with the rotating shaft 41, and the driving block 30 is vertically slidably installed at the lower end of the rotating shaft 41, and the lower end of the driving block 30 is provided with a metal outer edge, and the lifting of the driving block 30 is realized by the cooperation of the electromagnet and the outer edge. It is arranged on the pot cover 5, and the rotating shaft 41 will not be connected, so the position of the electromagnet is relatively fixed, and there is no need to worry about the arrangement of the circuit under the rotating state. At this time, the driving gear 22 in the transmission structure is installed on the front shaft 15 and separated from the rotating shaft 41.

[0079] In this embodiment, since the pot cover 5 can be turned over, the air inlet pipe 35 is a hose.
