Description

Technical Field

[0001] The utility model relates to the technical field of organic fertilizers, and particularly relates to a crushing device for organic fertilizer production. Background Art

[0002] Organic fertilizer is a kind of fertilizer made from animal and plant wastes or other natural organic substances through processes such as fermentation and composting. Organic fertilizer can improve soil structure, enhance the soil's water and fertilizer retention capacity, increase the content of soil organic matter, contribute to crop growth, and is also beneficial to environmental protection. During the production process of organic fertilizer, it is often necessary to crush the raw materials.

[0003] In the Chinese patent "A Crushing Device for Organic Fertilizer Production" with the authorization announcement number "CN 217164556U", the crushed fertilizer is screened through a sieve plate. The sieve plate retains the larger particles after crushing on the sieve plate. The driving motor drives the linkage shaft to rotate, and the linkage shaft drives the driving disk to perform eccentric circular motion. When the driving disk rotates to the position below the bias, the sieve plate rotates and tilts with the hinge point between the sieve plate and the inner wall of the bin as the rotation center due to the gravity of the fertilizer, so that the fertilizer on the sieve plate can be conveniently transported from the inclined sieve plate to the hopper and then transported out of the bin.

[0004] In the above solution, the crushed fertilizer can be crushed and screened. During the screening process of the sieve plate, continuously crushed raw materials will fall on the sieve plate. When the sieve plate rotates and tilts, some raw materials that have not been fully screened will be discharged from the bin together with the larger particle raw materials, resulting in the screening effect of the crushed raw materials.

[0005] Therefore, a crushing device for organic fertilizer production is proposed to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a crushing device for organic fertilizer production to solve the above problems, and improve the problem that during the screening process of the sieve plate, continuously crushed raw materials will fall on the sieve plate. When the sieve plate rotates and tilts, some raw materials that have not been fully screened will be discharged from the bin together with the larger particle raw materials, resulting in the screening effect of the crushed raw materials.

[0007] The present utility model realizes the above object through the following technical solutions. A pulverizing device for organic fertilizer production includes: a pulverizing box, and two pulverizing rollers are rotatably connected to the upper end of the inner wall of the pulverizing box; a screening mechanism, and the screening mechanism for fully screening the pulverized organic fertilizer is arranged inside the pulverizing box; wherein, the screening mechanism includes two first sieve plates respectively slidably connected to the inner wall of the pulverizing box, a connecting plate is fixedly connected to the bottom end of the first sieve plate, second sieve plates distributed in equal columns are fixedly connected between the opposite sides of the two connecting plates, a third sieve plate is fixedly connected between the opposite sides of two adjacent second sieve plates, and a receiving box is fixedly connected to one side of the pulverizing box.

[0008] Preferably, the screening mechanism further includes a first motor fixedly connected to the other side of the pulverizing box, an output shaft of the first motor penetrates into the interior of the pulverizing box and is fixedly connected with a cam, and a fixing plate is fixedly connected to the other side of one of the second sieve plates, and the bottom end of the fixing plate is attached to the surface of the cam. Starting the first motor to drive the cam to rotate is beneficial to making the first sieve plate, the second sieve plate and the third sieve plate move up and down reciprocally to screen the pulverized raw materials.

[0009] Preferably, two inclined plates are fixedly connected to the inner wall of the pulverizing box, and the two inclined plates and the horizontal plane form an isosceles triangle. It is beneficial to guide the pulverized raw materials to the higher positions of the two first sieve plates first, and it is beneficial to make the crushed raw materials pass through the two first sieve plates first and then through the second sieve plate and the third sieve plate, ensuring the effect of the first sieve plate for preliminary screening of the pulverized raw materials.

[0010] Preferably, both of the two first sieve plates are inclined, a slider is fixedly connected to the top end of the first sieve plate, a spring is fixedly connected to the top end of the slider, and the other end of the spring is fixedly connected to the inner wall of the pulverizing box. When the cam rotates continuously, under the action of the spring, it is beneficial to make the bottom end of the fixing plate better fit the surface of the cam.

[0011] Preferably, a guiding plate is fixedly connected to the other side of the other second sieve plate, the guiding plate is inclined, and the other end of the guiding plate penetrates into the interior of the receiving box. It is beneficial to make the larger particle raw materials better enter the receiving box.

[0012] Preferably, a protective plate is fixedly connected to one side of the first sieve plate, and one side of the protective plate is attached to the inner wall of the pulverizing box. It is beneficial to protect the limiting groove, prevent the raw materials from entering the limiting groove, and ensure the stability of the up and down movement of the slider.

[0013] Preferably, the horizontal heights of the tops of the multiple second sieve plates decrease in sequence, and the multiple third sieve plates are all inclined. This ensures that when screening the raw materials on the second sieve plates and the third sieve plates, the raw materials move downward obliquely, guaranteeing the screening effect of the multiple second sieve plates and the third sieve plates.

[0014] Preferably, limiting grooves are formed on both sides of the inner wall of the crushing box, and the surface of the sliding block is slidably connected to the inner wall of the limiting groove. This is beneficial for limiting the up-and-down movement of the first sieve plate.

[0015] The beneficial effects of the present utility model are as follows:

[0016] 1. With the setting of the screening mechanism, starting the first motor to drive the cam to rotate is beneficial for the first sieve plate, the second sieve plate, and the third sieve plate to move up and down reciprocally to screen the crushed raw materials. At the same time, making the crushed raw materials first fall above the two first sieve plates is beneficial for the two first sieve plates to conduct preliminary screening on the crushed raw materials, enabling the larger particle raw materials and some incompletely screened raw materials to slide down to the second sieve plate and the third sieve plate through the inclined surface of the first sieve plate, which is beneficial for reducing the screening pressure on the second sieve plate and the third sieve plate, and using the combination of the horizontal plane of the second sieve plate and the inclined surface of the third sieve plate to increase the residence time of the raw materials on the second sieve plate and the third sieve plate, which is beneficial for fully screening the incompletely screened raw materials, separating the crushed qualified raw materials from the larger particle raw materials better, thereby improving the screening effect of the crushed raw materials;

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] During specific implementation: As Figures 1-5 shown, a crushing device for organic fertilizer production, a crushing box 1, and two crushing rollers 2 are rotatably connected to the upper end of the inner wall of the crushing box 1; a screening mechanism 3 for fully screening the crushed organic fertilizer is arranged inside the crushing box 1; wherein, the screening mechanism 3 includes two first sieve plates 31 respectively slidably connected to the inner wall of the crushing box 1, a connecting plate 32 is fixedly connected to the bottom end of the first sieve plate 31, second sieve plates 33 distributed in equal columns are fixedly connected between the opposite sides of the two connecting plates 32, a third sieve plate 34 is fixedly connected between the opposite sides of two adjacent second sieve plates 33, and a material receiving box 35 is fixedly connected to one side of the crushing box 1.

[0026] An inlet is arranged at the top end of the crushing box 1, and an outlet is opened at the bottom end. One end of each of the two crushing rollers 2 penetrates out of the crushing box 1 and is fixedly connected with a gear, and the two gears are meshed. A protective frame is installed at the upper end of one side of the crushing box 1, a second motor is fixedly connected to the other side of the protective frame, the two gears are installed inside the protective frame, and the output shaft of the second motor penetrates to the inside of the protective frame and is fixedly connected with the other end of one of the gears.

[0027] When it is necessary to crush the raw materials of the organic fertilizer, the raw materials are put into the crushing box 1 from the inlet, and the second motor is started through the controller to drive the two gears to rotate. Since the two gears are meshed, the two crushing rollers 2 are driven by the two gears to rotate in opposite directions to crush the raw materials.

[0028] As Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, the screening mechanism 3 further includes a first motor 36 fixedly connected to the other side of the crushing box 1. The output shaft of the first motor 36 penetrates into the interior of the crushing box 1 and is fixedly connected with a cam 37. On the other side of one of the second sieve plates 33, a fixing plate 314 is fixedly connected. The bottom end of the fixing plate 314 is in contact with the surface of the cam 37. On the other side of the other second sieve plate 33, a guiding plate 311 is fixedly connected. The guiding plate 311 is inclined, and the other end of the guiding plate 311 penetrates into the interior of the material receiving box 35.

[0029] When crushing the raw materials, the crushed raw materials will first fall above the two first sieve plates 31. At this time, start the first motor 36 to drive the cam 37 to rotate. When the cam 37 rotates from the lowest end to the highest end and contacts the bottom end of the fixing plate 314, it will push the fixing plate 314 to move upward, and drive the second sieve plate 33, the third sieve plate 34, the first sieve plate 31 and the connecting plate 32 to move upward at the same time. When the cam 37 rotates from the highest point to the lowest point and contacts the bottom end of the fixing plate 314, under the action of the self-gravity of the raw materials, the second sieve plate 33, the third sieve plate 34, the first sieve plate 31 and the connecting plate 32 will automatically reset. Therefore, when the cam 37 continuously rotates, the second sieve plate 33, the third sieve plate 34 and the first sieve plate 31 will move up and down reciprocally to screen the crushed raw materials. Since the crushed raw materials first fall on the first sieve plate 31, the two first sieve plates 31 will conduct a preliminary screening on the crushed raw materials, so that some raw materials with smaller particles will fall through the mesh holes of the first sieve plate 31, and the larger particle raw materials and some raw materials that have not been fully screened will slide down to the second sieve plate 33 and the third sieve plate 34 through the inclined surface of the first sieve plate 31. When the second sieve plate 33 and the third sieve plate 34 reciprocally vibrate to screen the raw materials, the raw materials will move obliquely downward and will pass through different second sieve plates 33 and third sieve plates 34 multiple times. By combining the horizontal plane of the second sieve plate 33 and the inclined surface of the third sieve plate 34, the residence time of the raw materials on the second sieve plate 33 and the third sieve plate 34 is increased. After screening, the larger particle raw materials will enter the material receiving box 35 through the guiding plate 311.

[0030] As Figure 3 shown, two inclined plates 38 are fixedly connected to the inner wall of the crushing box 1. The two inclined plates 38 and the horizontal plane form an isosceles triangle. The lower end of the inclined plate 38 is located above the higher end of the corresponding first sieve plate 31, and the two inclined plates 38 are integrally inclined. When the crushing roller 2 crushes the raw materials, the crushed raw materials will fall on the inclined plates 38 and fall on the higher positions on one side of the two first sieve plates 38 through the inclined surfaces of the two inclined plates 38.

[0031] As Figure 2 、 Figure 3 and Figure 4As shown, both of the two first sieve plates 31 are inclined. The top end of the first sieve plate 31 is fixedly connected with a slider 39, and the top end of the slider 39 is fixedly connected with a spring 310. The other end of the spring 310 is fixedly connected with the inner wall of the crushing box 1. Limiting grooves 313 are formed on both sides of the inner wall of the crushing box 1, and the surface of the slider 39 is slidably connected with the inner wall of the limiting groove 313. When the first sieve plate 31 moves up and down, it will drive the slider 39 to move up and down synchronously along the inner wall of the limiting groove 313. When the cam 37 pushes the fixing plate 314 to move upward, the slider 39 moves upward and compresses the spring 310. When the fixing plate 314 loses the extrusion, the spring 310 will push the slider 39 to automatically reset.

[0032] As Figure 3 and Figure 4 shown, a protective plate 312 is fixedly connected to one side of the first sieve plate 31, and one side of the protective plate 312 is attached to the inner wall of the crushing box 1. The position of the protective plate 312 corresponds to the position of the limiting groove 313. When the first sieve plate 31 moves up and down, it will drive the protective plate 312 to move up and down synchronously and block the limiting groove 313.

[0033] As Figure 5 shown, the horizontal heights of the tops of multiple second sieve plates 33 decrease in sequence, and multiple third sieve plates 34 are all inclined. The multiple second sieve plates 33 and the multiple third sieve plates 34 as a whole form an inclined plane sloping downward.

[0034] When the present utility model is in use, when crushing the raw materials of organic fertilizer, the raw materials are put into the crushing box 1 from the feed inlet, and two crushing rollers 2 are driven to rotate in opposite directions to crush the raw materials. The crushed raw materials will fall on the inclined plate 38 and fall on the higher positions on one side of the two first sieve plates 31 through the inclined surfaces of the two inclined plates 38. At this time, the first motor 36 is started to drive the cam 37 to rotate. When the cam 37 continuously rotates, under the action of the self - gravity of the raw materials and the spring 310, the second sieve plates 33, the third sieve plates 34, and the first sieve plates 31 will move up and down reciprocally to screen the crushed raw materials. Since the crushed raw materials first fall on the first sieve plates 31, the two first sieve plates 31 will conduct a preliminary screening on the crushed raw materials, enabling some smaller - particle raw materials to fall through the mesh holes of the first sieve plates 31, and the larger - particle raw materials and some raw materials that are not fully screened will fall on the second sieve plates 33 and the third sieve plates 34 through the inclined surfaces of the first sieve plates 31. Since the multiple second sieve plates 33 and the multiple third sieve plates 34 as a whole form an inclined plane sloping downward, when the second sieve plates 33 and the third sieve plates 34 reciprocally vibrate to screen the raw materials, the raw materials will move obliquely downward and pass through different second sieve plates 33 and third sieve plates 34 multiple times. By combining the horizontal plane of the second sieve plates 33 and the inclined plane of the third sieve plates 34, the residence time of the raw materials on the second sieve plates 33 and the third sieve plates 34 is increased. After screening, the larger - particle raw materials will enter the receiving box 35 through the guiding plate 311.

[0035] It should be noted that the first motor 36, the second motor, etc. in the above description are all devices with relatively mature applications in the prior art. The specific models can be selected according to actual needs. At the same time, the power supply for the first motor 36 and the second motor can be an internal power supply or a mains power supply. The specific power supply method is selected according to the situation and will not be elaborated here.

[0036] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
