Description

Technical Field

[0001] The present invention belongs to the technical field of conveyors, and particularly relates to an organic fertilizer production conveyor with a function of preventing material blockage. Background Art

[0002] Organic fertilizers, especially tobacco dust organic fertilizers, involve the mixing and transportation of various raw materials in the production process. Among them, tobacco dust, as one of the important raw materials, due to its own water content and plant characteristics, during transportation, when the temperature rises due to friction, the particles will expand, which will cause the blockage of the conveyor. Therefore, how to solve the problem of blockage caused by the expansion of water-containing plant raw materials during transportation is a problem that needs to be solved by those skilled in the art.

[0003] The patent with the existing publication number CN222845887U discloses a new type of spiral conveyor for powdery additives, including a spiral shaft and a feed bin. The spiral shaft includes a spiral inner tube, spiral blades, a fixed outer tube, and a stirring mechanism. The spiral inner tube is installed inside the fixed outer tube through bearings, and spiral blades are arranged on the spiral inner tube. The spiral inner tube drives the spiral blades to rotate and convey materials. The feed bin is connected to the fixed outer tube, and multiple groups of stirring mechanisms are arranged in the feed bin. The stirring mechanisms are installed on the spiral inner tube. This utility model adopts a feed bin with a large diameter and a large cavity to ensure the feeding volume of the powdery additive during transportation. And multiple groups of stirring knives are installed on the spiral shaft. The stirring knives and the stirring columns break up the lumps of the powdery additive in the feed bin and dredge the blocked material, ensuring smooth feeding, making the transportation of the powder additive more stable, facilitating subsequent accurate metering, ensuring the mixing quality in the later stage, and improving the transportation efficiency of the powder additive.

[0004] The existing technology has the following disadvantages:

[0005] Multiple groups of stirring knives are installed on the spiral shaft. The stirring knives and the stirring columns break up the lumps of the powdery additive in the feed bin and dredge the blocked material. However, after the water-containing plant raw materials and other raw materials are fully mixed, the viscosity increases. At the same time, the water-containing plant raw materials are heated up and expanded due to the friction with the pipeline and the spiral blades during the spiral transportation process, and finally it is easy to form a blockage between the spiral blades. Therefore, only breaking up the lumps in the feed bin cannot completely avoid the blockage in the conveyor. Summary of the Invention

[0006] The present invention provides an organic fertilizer production conveyor with a function of preventing material blockage, which can solve the technical problem in the existing technology that only breaking up the lumps in the feed bin cannot completely avoid the blockage caused by the heat expansion of water-containing plant raw materials in the conveyor.

[0007] In order to achieve the above object, the present invention is realized through the following technical solutions:

[0008] The present application provides an organic fertilizer production conveyor with an anti-blocking function, which includes a shell, a driving shaft and a main spiral blade, the shell forms a conveying channel, and the shell is provided with a feed port and a discharge port; the driving shaft is rotatably connected to the shell, and the driving shaft is transmission-connected to a driving motor; the main spiral blade is connected to the outer side of the driving shaft, and the main spiral blade conveys the material along the length direction of the shell under the drive of the driving shaft, and the main spiral blade has a variable capacity space inside, and the variable capacity space changes the spiral pitch of the main spiral blade when it contracts or expands, and the material falls out of or squeezes out of the main spiral blade after the spiral pitch changes.

[0009] Through the above technical scheme, a main spiral blade with a variable spiral pitch is used. After the material absorbs water and expands due to heat and blocks the conveyor, the spiral pitch can be changed to release the blocked material and continue to be conveyed, thereby completely avoiding the technical problem of blockage caused by the thermal expansion of water-containing plant raw materials and improving the continuous conveying performance of the conveyor.

[0010] In the present invention, the main spiral blade includes a scraper, a transfer groove, a first blade, a second blade and an air hole. The scraper is in sliding contact with the inner surface of the shell, and the scraper is used to scrape off the material attached to the inner surface of the shell; the transfer groove is fixedly connected to the outer surface of the driving shaft; the first blade and the second blade are connected in parallel between the scraper and the transfer groove, and a variable volume space is formed between the scraper, the first blade, the second blade and the transfer groove; the air hole is opened in the transfer groove, and the air hole is used to supply and exhaust gas to the variable volume space.

[0011] Through the above technical solution, two blades are used to form a variable capacity space, and the variable capacity is achieved through the air supply and exhaust of the air holes, thereby improving the response speed of the variable capacity.

[0012] In the present invention, the above-mentioned conveyor also includes a rotary joint, which is connected to the end of the driving shaft away from the driving motor. A blind hole is drilled at the axis of the driving shaft, and a through hole is drilled on the side wall of the blind hole. The through hole and the air hole are arranged correspondingly, and the rotary joint is connected to an external air source to inflate and deflate the variable volume space.

[0013] Through the above technical solution, a rotary joint is adopted to realize that a fixed external air source is used to charge and discharge the variable volume space through a rotating active shaft.

[0014] In the present invention, the above-mentioned rotary joint has a rotating part, a fixed part, an air inlet joint, and an exhaust pipe. The rotating part is coaxially and fixedly connected to the active shaft; the fixed part is rotatably and sealingly connected to the rotating part; the air inlet joint is connected to the fixed part, and the air inlet joint is used to connect to the external air source; the exhaust pipe is coaxially arranged with the air inlet joint, and the exhaust pipe is connected with a solenoid valve. When the air inlet joint blows air into the exhaust pipe, a negative pressure is formed at the opening of the blind hole to discharge the gas in the variable volume space.

[0015] Through the above technical solution, a three-way rotary joint is adopted, and the air intake and exhaust of the blind hole are controlled by controlling the opening and closing of the exhaust pipe, which simplifies the air circuit control.

[0016] In the present invention, the above-mentioned conveyor further includes a magnetic coupling, and the magnetic coupling is connected between the active shaft and the driving motor.

[0017] Through the above technical solution, a magnetic coupling is adopted to reduce the fluctuation of the load on the driving motor caused by the reduction of the rotational speed of the active shaft due to the viscosity of the material, and improve the service life of the driving motor.

[0018] In the present invention, the above-mentioned conveyor further includes a driven shaft and a secondary spiral blade. The driven shaft is rotatably connected to the housing, the driven shaft is arranged parallel to the active shaft, and the driven shaft rotates synchronously with the active shaft; the secondary spiral blade is fixedly connected to the driven shaft, and the secondary spiral blade does not interfere with the main spiral blade during rotation, and the secondary spiral blade is used to disperse the material between the main spiral blades.

[0019] Through the above technical solution, the driven shaft rotates synchronously with the active shaft, and the material between the gaps of the main spiral blades is dispersed by the secondary spiral blade, further reducing the risk of blockage.

[0020] In the present invention, the above-mentioned conveyor further includes a main reverse spiral blade and a secondary reverse spiral blade. The main reverse spiral blade is connected to one end of the active shaft away from the feed inlet; the secondary reverse spiral blade is connected to one end of the driven shaft away from the feed inlet.

[0021] Through the above technical solution, reverse spiral blades are adopted to make the materials in the housing finally converge above the discharge port, so that the materials can fully leave the housing. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0037] Embodiment:

[0038] Please refer to Figures 1 to 9 , Figures 1 to 9 which shows an embodiment of the present application.

[0039] This embodiment provides an organic fertilizer production conveyor with a function of preventing material blockage. As shown in Figure 1 and Figure 2 , it includes a housing 4, a driving shaft 1, and a main spiral blade 2. The housing 4 forms a conveying channel. The housing 4 is provided with a feed inlet 401 and a discharge outlet, and the discharge outlet is opened below one end of the housing 4 away from the feed inlet 401. The driving shaft 1 is rotatably connected to the housing 4 through a sealed bearing, and the driving shaft 1 is drivingly connected to a driving motor 6. The main spiral blade 2 is welded to the outside of the driving shaft 1. The main spiral blade 2 drives the material to be conveyed along the length direction of the housing 4 under the drive of the driving shaft 1. As shown in Figure 4 and Figure 5 , the main spiral blade 2 has a variable volume space inside. When the variable volume space contracts or expands, the spiral pitch of the main spiral blade 2 is changed. After the spiral pitch is changed, the material falls out of or is extruded from the main spiral blade 2.

[0040] Through the above technical solution, by adopting the main spiral blade 2 with variable spiral pitch, after the material absorbs water and expands due to heat and gets blocked in the conveyor, the blocked material can be released by changing the spiral pitch and continue to be conveyed, thereby completely avoiding the technical problem of blockage caused by the expansion of the water-containing plant raw material due to heat, and improving the continuous conveying performance of the conveyor.

[0041] As a preferred implementation, as Figure 3 shown, the above-mentioned main spiral blade 2 includes a scraper 201, a transition groove 204, a first blade 202, a second blade 203 and an air hole 205. The scraper 201 is in sliding contact with the inner surface of the housing 4, and the scraper 201 is used to scrape the material attached to the inner surface of the housing 4; the transition groove 204 is welded to the outer surface of the driving shaft 1; the first blade 202 and the second blade 203 are connected in parallel between the scraper 201 and the transition groove 204. The first blade 202 and the second blade 203 are made of elastic thin sheet metal material. After processing the slots on both sides and twisting and forming (as Figure 4 shown, the cross section of the first blade 202 and the second blade 203 after processing and forming is arc-shaped), the slots at both ends are respectively inserted into the slots of the scraper 201 and the transition groove 204 and then welded. After welding, the welded part needs to be ground, polished, and water is injected to detect airtightness. A variable volume space is formed between the scraper 201, the first blade 202, the second blade 203 and the transition groove 204; the air hole 205 is opened in the transition groove 204, and the air hole 205 is used for supplying and exhausting air to the variable volume space.

[0042] Specifically, the scraper 201, the transition groove 204, the first blade 202, and the second blade 203 are respectively processed and formed. The transition groove 204 is welded to the outside of the driving shaft 1, and then the air hole 205 is drilled to connect the air hole 205 with the blind hole in the driving shaft 1. Then the first blade 202 and the second blade 203 are inserted into the groove of the transition groove 204, and finally the scraper 201 is inserted outside the first blade 202 and the second blade 203 and assembled into the structure as Figure 3 shown. Then the gaps are welded, ground, and polished. Finally, water is injected through the blind hole of the driving shaft 1 to observe whether there is water leakage in the main spiral blade 2.

[0043] During operation, a medium is introduced to expand the variable volume space to the Figure 4 state and maintain a certain pressure to maintain the structural stability of the main spiral blade 2. When the material discharge slows down, gets blocked or the medium is periodically emptied manually (automatically), the variable volume space shrinks to the Figure 5 state. The external space change formed by expansion and contraction reduces the compaction degree of the external material. It should be noted that when the variable volume space shrinks, the rotation speed of the driving motor 6 needs to be synchronously reduced (disconnect the transmission between the driving motor 6 and the driving shaft 1 if necessary) to avoid more material entering the space between the pitches of the main spiral blade 2.

[0044] It should be noted that the scraper 201 is spiral in shape as a whole and is restricted by the shell 4 so as not to increase the diameter of the spiral. The first blade 202 and the second blade 203 are elastic metal sheets which have no ductility or low ductility (i.e. Figure 4 or Figure 5 The lengths of the two will not change), so the relative positions of the scraper 201 and the adapter groove 204 will not change. In order to facilitate understanding of this dynamic change, you can refer to the metal bottle cap of a canned fruit in a glass bottle. When there is a negative pressure in the can, the bottle cap is concave and can be eaten normally. When bacteria grow in the can or there is a leak, the bottle cap pops up and cannot be eaten normally. The changes in the different positions of the blades are based on the elasticity of the metal sheet. This change process will be rapid and have a relatively large impact force, thereby vibrating off some of the attached materials.

[0045] Through the above technical solution, two blades are used to form a variable capacity space, and the variable capacity is achieved through the air supply and exhaust of the air hole 205, thereby improving the response speed of the variable capacity.

[0046] As a preferred implementation method, Figure 7 As shown, the above-mentioned conveyor also includes a rotary joint 5, which is connected to the end of the driving shaft 1 away from the driving motor 6. A blind hole is drilled at the axis of the driving shaft 1, and a through hole is drilled on the side wall of the blind hole. The through hole and the air hole 205 are arranged correspondingly. The rotary joint 5 is connected to an external air source to inflate and deflate the variable volume space.

[0047] The rotary joint 5 is a prior art, and a person skilled in the art can purchase a suitable size and model through public channels.

[0048] Through the above technical solution, the rotary joint 5 is adopted to realize that the fixed external air source is used to charge and discharge the variable volume space through the rotating driving shaft 1.

[0049] As a preferred implementation method, Figure 8 and Figure 9 As shown, the above-mentioned rotary joint 5 has a rotating part 501, a fixed part 502, an air inlet connector 5021 and an exhaust pipe 5022, the rotating part 501 is coaxially fixedly connected to the driving shaft 1; the fixed part 502 is rotationally sealedly connected to the rotating part 501; the air inlet connector 5021 is connected to the fixed part 502, and the air inlet connector 5021 is used to connect to an external air source; the exhaust pipe 5022 is coaxially arranged with the air inlet connector 5021, and the exhaust pipe 5022 is connected to the solenoid valve 503. When the air inlet connector 5021 blows air to the exhaust pipe 5022, a negative pressure is formed at the opening of the blind hole to discharge the gas in the variable volume space.

[0050] When in use, an air compressor is selected as the external air source. During the inflation stage, the solenoid valve 503 is closed, and the gas enters from the air inlet connector 5021, passes through the blind hole of the driving shaft 1, and is filled into the variable volume space through the air hole 205 to make the two blades pop outward, reducing the spiral pitch of the main spiral blade 2. When exhaust is required, the solenoid valve 503 is opened. When the air flow is quickly discharged from the air inlet connector 5021 directly through the exhaust pipe 5022, a negative pressure is formed at the opening of the blind hole because the flow rate of the gas increases, thereby exhausting the gas in the blind hole, which causes the main spiral blade 2 to be ejected. Figure 4 The state changes to Figure 5 state.

[0051] It should be noted that the external air source does not belong to the technical improvement part of the present application, and technical personnel with this skill can purchase suitable models through public channels, so it is not further described and specifically limited here. At the same time, the pressure and speed regulating device that matches the air compressor can also be selectively installed by technical personnel in this field according to actual use. For the control of air pressure and the occurrence of blade deformation, technical personnel in this field can obtain applicable parameters by adjusting the parameters through a limited number of tests. The specific parameters do not belong to the protection scope of this application, so it is not further described and specifically limited.

[0052] Through the above technical solution, a three-way rotary joint 5 is used to control the opening and closing of the exhaust pipe 5022 to control the air intake and exhaust of the blind hole, thereby simplifying the air path control.

[0053] As a preferred embodiment, the conveyor further includes a magnetic coupling 7 , which is connected between the driving shaft 1 and the driving motor 6 .

[0054] The magnetic coupler 7 adopts a non-contact magnetic transmission method. In order to simplify the structure and control unit, a double-sided permanent magnet configuration can be selected. In order to obtain a more adjustable option, a single-sided or double-sided electromagnet configuration can be selected. The transmission ratio can be changed by changing the current size and the number of turns of the working coil.

[0055] Through the above technical solution, the magnetic coupler 7 is adopted to reduce the fluctuation of the load on the drive motor 6 caused by the reduction of the rotation speed of the driving shaft 1 due to the viscosity of the material, thereby increasing the service life of the drive motor 6.

[0056] As a preferred implementation method, Figure 2 , Figure 6 and Figure 7 As shown, the above-mentioned conveyor also includes a driven shaft 3 and an auxiliary spiral blade. The driven shaft 3 is rotatably connected to the shell 4. The driven shaft 3 is arranged in parallel with the driving shaft 1, and the driven shaft 3 rotates synchronously with the driving shaft 1. The auxiliary spiral blade is fixedly connected to the driven shaft 3, and the auxiliary spiral blade and the main spiral blade 2 do not interfere with each other when rotating. The auxiliary spiral blade is used to break up the material between the main spiral blades 2.

[0057] Synchronous rotation is based on the meshing of the driving gear 102 and the driven gear 302 with the same number of teeth. However, because there is a large distance between the main helical blade 2 and the auxiliary helical blade, even if the gears are worn and there is a slight relative displacement, it will not affect the rotation of the auxiliary helical blade and the main helical blade 2 without interfering with each other. If necessary, maintenance personnel will replace the gears.

[0058] The auxiliary spiral blade and the main spiral blade 2 do not interfere with each other when they rotate. Figure 2 It can be clearly seen that the pitch of the two is in a 2:1 ratio, and there is a certain angle difference. When the two rotate synchronously, the pitch will always remain the same (without damage or wear).

[0059] Through the above technical solution, the driven shaft 3 is rotated synchronously with the driving shaft 1, and the materials in the gaps between the main spiral blades 2 are broken up by the auxiliary spiral blades, thereby further reducing the wind direction of the material blockage.

[0060] As a preferred embodiment, the above-mentioned conveyor also includes a main reverse spiral blade 101 and a secondary reverse spiral blade 301. The main reverse spiral blade 101 is connected to the end of the driving shaft 1 away from the feed port 401; the secondary reverse spiral blade 301 is connected to the end of the driven shaft 3 away from the feed port 401.

[0061] Through the above technical solution, the reverse spiral blades are used to make the materials in the shell 4 finally gather above the discharge port, so that the materials can fully leave the shell 4.

[0062] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope of the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
