Description

Technical Field

[0001] The utility model relates to the technical field of organic fertilizer production, in particular to an organic fertilizer mixing and stirring device which is convenient for discharging. Background Art

[0002] Organic fertilizer refers to a fertilizer obtained from natural organic matter such as animal and plant residues, feces, straw, algae, and fungi, which is fermented, decomposed, and processed. In the production process of organic fertilizer, in order to improve the uniformity and nutrient utilization rate of organic fertilizer and promote the action of microorganisms, the raw materials need to be mixed during the production process of organic fertilizer.

[0003] The Chinese patent "An organic fertilizer mixing and stirring device" authorization announcement number "CN 210752149U" is equipped with a discharging stirring paddle at the discharging port, which can also prevent the channel from being blocked and make the discharging smoother.

[0004] The above application can realize the material unloading operation, but because the raw materials are mixed and then unloaded, the raw materials will accumulate on the top of the stirring paddle. When the stirring paddle rotates to unload the materials, the accumulated raw materials will cause a large rotational resistance of the stirring paddle, which will easily make the unloading unstable and unable to be unloaded evenly.

[0005] Therefore, an organic fertilizer mixing and stirring device that is convenient for discharging is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide an organic fertilizer mixing and stirring device which is convenient for discharging in order to solve the above-mentioned problem, and to improve the problem that when the raw materials are mixed and discharged, the raw materials will accumulate on the top of the stirring paddle. When the stirring paddle is rotated to discharge the materials, the accumulated raw materials will cause the rotation resistance of the stirring paddle to be large, which will easily make the discharge unstable and unable to discharge evenly.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme, an organic fertilizer mixing and stirring device that is convenient for discharging, comprising: a mixing drum, the top end of the mixing drum is fixedly connected to a servo motor, the inner wall of the mixing drum is rotatably connected to a stirring rod, the top end of the stirring rod passes through the mixing drum and is fixedly connected to the output shaft of the servo motor, and the lower end of the inner wall of the mixing drum is provided with a feeding mechanism; wherein the feeding mechanism comprises a feeding hopper fixedly connected to the lower end of the inner wall of the mixing drum, a plurality of feeding ports are provided at the bottom end of the feeding hopper, a fixing ring is fixedly connected to the bottom end of the inner wall of the fixing ring, a circular ring is rotatably connected to the lower end of the mixing drum, a discharge pipe is fixedly connected to the bottom end of the mixing drum, the top end of the discharge pipe passes through the interior of the mixing drum and is rotatably connected to the bottom end of the circular ring, and a stirring paddle is rotatably connected to the inner wall of the discharge pipe.

[0008] Preferably, the feeding mechanism further comprises a rotating rod rotatably connected to the inner wall of the stirring rod, the bottom end of the rotating rod passes through the lower hopper and is fixedly connected to a circular plate, the surface of the rotating rod is rotatably connected to the inner wall of the lower hopper, the surface of the circular plate is fixedly connected to a plurality of blocking plates, the top of the blocking plates is in contact with the bottom end of the lower hopper. After the fertilizers are mixed, the interaction between the plurality of blocking plates and the lower hopper is used to separate the mixed fertilizers from the stirring paddle, thereby preventing the fertilizers from accumulating on the stirring paddle.

[0009] Preferably, the bottom end of the blocking plate is fixedly connected to a connecting rod, the other end of the connecting rod is fixedly connected to the inner wall of the circular ring, the surface of the circular ring is fixedly connected to a fixing rod, the other end of the fixing rod is fixedly connected to an extrusion block, the lower end of the inner wall of the mixing barrel is slidably connected to a moving ring, the surface of the extrusion block fits with the bottom end of the moving ring, the bottom end of the moving ring is fixedly connected to push blocks distributed in equal rows, and the top end of the moving ring is fixedly connected to trigger rods distributed in equal rows. Under the interaction of multiple push blocks and extrusion blocks, it is beneficial for the extrusion blocks to push the moving ring to move up and down during continuous rotation, and it is beneficial for the trigger rod to continuously collide with the lower hopper to vibrate the lower hopper, so that the fertilizer in the lower hopper can better slide through the inclined surface of the inner wall of the lower hopper to the inner bottom wall of the lower hopper, thereby ensuring the stability of the feeding process.

[0010] Preferably, a one-way bearing is embedded and installed at the bottom end of the stirring rod, and the inner edge of the one-way bearing is fixedly connected to the surface of the rotating rod. Under the action of the one-way bearing, when the stirring rod rotates clockwise to stir the raw materials, the rotating rod is prevented from rotating synchronously, thereby ensuring the stability of the sealing plate blocking the discharge port when the raw materials are mixed, and preventing the raw materials that are not completely mixed from falling through the discharge port.

[0011] Preferably, the surface of the rotating rod is fixedly connected with a scraper distributed in an annular shape, and the bottom end of the scraper is in contact with the inner bottom wall of the hopper. When the material is discharged from the discharge port, the scraper is rotated to scrape the fertilizer on the inner bottom wall of the hopper, which is conducive to making the fertilizer fall through the discharge port better and ensuring normal discharge operation.

[0012] Preferably, the shapes of the extrusion block and the push block are both half spherical, and the diameter of the extrusion block is larger than the diameter of the push block, which is conducive to better contact between the extrusion block and the push block, and pushes the push block to move upward.

[0013] Preferably, an angle is formed between the top of the trigger rod and the horizontal plane, which is beneficial for the trigger rod to better contact with the surface of the lower hopper when it collides with the lower hopper.

[0014] The beneficial effects of the utility model are:

[0015] 1. By setting up a feeding mechanism, after the fertilizer is mixed, the interaction between multiple blocking plates and the feeding hopper is used to separate the mixed fertilizer from the stirring paddle, and avoid the fertilizer from accumulating on the stirring paddle. At the same time, during the feeding process, the plugging plate is driven by the rotating rod to rotate continuously, so that the plugging plate intermittently blocks the feeding port, which is conducive to intermittent and uniform feeding at the feeding port. At the same time, the setting of multiple feeding ports prevents the fertilizer from accumulating on the stirring paddle when it falls through the feeding port, which is conducive to the stirring paddle to better discharge the stirred fertilizer and ensure the stability of the feeding process.

[0016] 2. Under the interaction of multiple push blocks and extrusion blocks, the extrusion blocks are conducive to pushing the moving ring to move up and down during the continuous rotation process, which is conducive to driving the trigger rod to continuously collide with the lower hopper to vibrate the lower hopper, so that the fertilizer in the lower hopper can better slide through the inclined surface of the inner wall of the lower hopper to the inner bottom wall of the lower hopper, ensuring the stability of the feeding process;

[0017] 3. Under the action of the one-way bearing, when the stirring rod rotates clockwise to stir the raw materials, the rotating rod is prevented from rotating synchronously, which ensures the stability of the sealing plate blocking the discharge port when the raw materials are mixed, and prevents the raw materials that are not completely mixed from falling through the discharge port.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] When implementing: Figure 1-5 As shown, an organic fertilizer mixing and stirring device that is easy to discharge comprises: a mixing drum 1, a servo motor 2 is fixedly connected to the top of the mixing drum 1, a stirring rod 3 is rotatably connected to the inner wall of the mixing drum 1, the top of the stirring rod 3 passes through the mixing drum 1 and is fixedly connected to the output shaft of the servo motor 2, and a feeding mechanism 4 is arranged at the lower end of the inner wall of the mixing drum 1; wherein the feeding mechanism 4 comprises a feeding hopper 41 fixedly connected to the lower end of the inner wall of the mixing drum 1, a plurality of feeding ports 42 are provided at the bottom end of the feeding hopper 41, a fixing ring 43 is fixedly connected to the bottom end of the inner wall of the fixing ring 43, a circular ring 44 is rotatably connected to the lower end of the inner wall, a discharge pipe 45 is fixedly connected to the bottom end of the mixing drum 1, the top of the discharge pipe 45 passes through the interior of the mixing drum 1 and is rotatably connected to the bottom end of the circular ring 44, and a stirring paddle 46 is rotatably connected to the inner wall of the discharge pipe 45.

[0026] A feeding port is provided at the top of the mixing drum 1, and raw materials can be put into the mixing drum 1 through the feeding port for mixing. During mixing, the servo motor 2 is started by the controller to drive the stirring rod 3 to rotate clockwise to mix and stir the organic fertilizer raw materials.

[0027] The stirring paddle 46 has the same structure as that in the original solution. The driving motor is fixed at the bottom end of the mixing barrel 1. One end of the stirring paddle 46 passes through the discharge pipe 45 and is fixedly connected to the output shaft of the driving motor.

[0028] like Figure 2 , Figure 3 and Figure 4 As shown, the feeding mechanism 4 further includes a rotating rod 47 rotatably connected to the inner wall of the stirring rod 3, the bottom end of the rotating rod 47 passes through the lower hopper 41 and is fixedly connected to a circular plate 48, the surface of the rotating rod 47 is rotatably connected to the inner wall of the lower hopper 41, and a plurality of blocking plates 49 are fixedly connected to the surface of the circular plate 48, and the top of the blocking plate 49 is in contact with the bottom end of the lower hopper 41. A one-way bearing 416 is embedded and installed at the bottom end of the stirring rod 3, and the inner edge of the one-way bearing 416 is fixedly connected to the surface of the rotating rod 47.

[0029] The number of blocking plates 49 is the same as the number of feed openings 42, and the width of the blocking plates 49 is greater than the width of the feed openings 42. When the device is in the initial state, the blocking plates 49 are located below the corresponding feed openings 42 to block the feed openings 42 to prevent the raw materials from falling from the feed openings 42 during the mixing process.

[0030] The inner wall of the stirring rod 3 is fixedly connected to the outer edge of the one-way bearing 416. When the output shaft of the servo motor 2 drives the stirring rod 3 to rotate clockwise, the rotating rod 47 remains stable.

[0031] When the raw materials are mixed and discharged, the mixed fertilizer will gather in the discharge hopper 41. At this time, the servo motor 2 is started through the controller, so that the output shaft of the servo motor 2 drives the stirring rod 3 to rotate slowly counterclockwise, thereby driving the rotating rod 47 to rotate synchronously. The slow counterclockwise rotation of the stirring rod 3 does not affect the discharging operation. When the rotating rod 47 rotates, it will drive the four blocking plates 49 to rotate synchronously through the circular plate 48, so that the four blocking plates 49 release the blockage of the four discharge ports 42. At this time, the fertilizer in the discharge hopper 41 will fall from the discharge port 42 and fall on the stirring paddle 46. The stirring paddle 46 can be started to rotate for discharging. When the circular plate 48 rotates to drive the blocking plate 49 to overlap with the discharge port 42 again, the discharge port 42 will be blocked again. The blocking plate 49 continues to rotate to achieve intermittent and uniform discharging.

[0032] like Figure 4 and Figure 5 As shown, the bottom end of the blocking plate 49 is fixedly connected to a connecting rod 410, the other end of the connecting rod 410 is fixedly connected to the inner wall of the ring 44, the surface of the ring 44 is fixedly connected to a fixing rod 411, the other end of the fixing rod 411 is fixedly connected to an extrusion block 412, the lower end of the inner wall of the mixing barrel 1 is slidably connected to a moving ring 413, the surface of the extrusion block 412 is fitted to the bottom end of the moving ring 413, the bottom end of the moving ring 413 is fixedly connected to push blocks 414 distributed in equal rows, and the top of the moving ring 413 is fixedly connected to trigger rods 415 distributed in equal rows. The shapes of the extrusion block 412 and the push block 414 are both half spherical, and the diameter of the extrusion block 412 is larger than the diameter of the push block 414.

[0033] When the rotating rod 47 drives the circular plate 48 and the sealing plate 49 to rotate, the circular ring 44 will be driven to rotate synchronously under the action of the connecting rod 410, thereby driving the fixed rod 411 and the extrusion block 412 to rotate, and the rotation path of the extrusion block 412 will coincide with the annularly distributed pushing block 414. When the extrusion block 412 rotates and contacts with the pushing block 414 and continues to rotate, the extrusion block 412 will push the pushing block 414 to move upward, thereby driving the moving ring 413 and the trigger rod 415 to move upward synchronously, so that the top end of the trigger rod 415 collides with the lower hopper 41, causing the lower hopper 41 to vibrate, so that the fertilizer in the lower hopper 41 can better slide through the inclined surface of the inner wall of the lower hopper 41 to the inner bottom wall of the lower hopper 41. When the extrusion block 412 continues to rotate, it will release the contact with the pushing block 414. At this time, since the moving ring 413 itself has a certain gravity, when the extrusion block 412 releases the extrusion of the pushing block 414, the moving ring 413 will automatically reset.

[0034] like Figure 4 As shown, the surface of the rotating rod 47 is fixedly connected with a scraper 417 distributed in an annular shape, and the bottom end of the scraper 417 is in contact with the inner bottom wall of the lower hopper 41. The number of scrapers 417 is set to four. In the initial state of the device, the scrapers 417 and the lower material port 42 are staggered. When the rotating rod 47 drives the blocking plate 49 to rotate to release the blocking of the lower material port 42, the scraper 417 will rotate synchronously to scrape the fertilizer on the inner bottom wall of the lower material hopper 41, so that the fertilizer can fall through the lower material port 42 better.

[0035] like Figure 5 As shown, an angle is formed between the top of the trigger rod 415 and the horizontal plane. The inclination of the inclined surface at the top of the trigger rod 415 is the same as the inclination of the surface of the lower hopper 41.

[0036] When the utility model is in use, when the raw materials are mixed and discharged, the servo motor 2 is started through the controller, so that the stirring rod 3 drives the rotating rod 47 to rotate slowly counterclockwise. When the rotating rod 47 rotates, the four blocking plates 49 are driven to rotate synchronously through the circular plate 48, so that the four blocking plates 49 intermittently release the blockage of the four discharge ports 42. After the discharge ports 42 are unblocked, the fertilizer in the discharge hopper 41 will fall from the discharge ports 42 onto the stirring paddle 46, and the stirring paddle 46 is started to rotate for discharge. At the same time, when the rotating rod 47 drives the blocking plate 49 to rotate to release the blockage of the discharge port 42, the scraper 417 will rotate synchronously to the bottom wall of the discharge hopper 41. The fertilizer is scraped so that the fertilizer can better fall through the discharge port 42. At the same time, when the blocking plate 49 rotates, the ring 44, the fixed rod 411 and the extrusion block 412 will be driven to rotate synchronously under the action of the connecting rod 410. During the continuous rotation of the extrusion block 412, it will continuously contact the push block 414 and push the push block 414 to move upward, thereby driving the moving ring 413 and the trigger rod 415 to move upward synchronously, so that the top end of the trigger rod 415 collides with the lower hopper 41, causing the lower hopper 41 to vibrate, so that the fertilizer in the lower hopper 41 can better slide through the inclined surface of the inner wall of the lower hopper 41 to the inner bottom wall of the lower hopper 41 for discharge.

[0037] It should be noted that the servo motor 2, drive motor, etc. in the above description are all relatively mature devices in existing technology applications. The specific models can be selected according to actual needs. At the same time, the servo motor 2 and drive motor can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0038] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
