Description

Technical Field

[0001] The utility model relates to the field of organic fertilizer screening machines, and particularly relates to a screening machine for organic fertilizer production with a dust removal mechanism. Background Art

[0002] Organic fertilizer is a natural organic substance derived from animals, plants, microorganisms and their metabolites, and is widely used in agricultural production. It can improve soil structure and soil fertility. At present, in the process of organic fertilizer production, a screening device is needed to classify organic fertilizer particles according to different target particle sizes, so that the particle sizes of organic fertilizers are more uniform, which is beneficial to the uniformity and effect during application.

[0003] In the Chinese patent "A Screening Machine for Organic Fertilizer Processing" with the authorization announcement number "CN 220479361 U", when the fertilizer is put into the screening box for shaking and screening, the exhaust fan is started, and the dust generated by shaking in the screening box is sucked into the filter box by using the air expansion hopper and the ventilation box. Through the isolation net, large particle fertilizers are isolated. Then, the submersible pump is started to transport the water inside the filter box to the atomization disk through the water pipe for atomization and spraying, which is used to filter the dust sucked into the filter box, achieving the dust removal effect and avoiding being inhaled by the staff, causing harm to the human body and polluting the environment and the atmosphere.

[0004] In the above solution, the dust during the screening process of organic fertilizer can be treated, but the positions of the air expansion hopper and the ventilation box are fixed. When the sieve mesh vibrates to screen the organic fertilizer, the dust will continuously change in the screening box, and it can only adsorb the dust from the same position, resulting in a reduced adsorption effect on the dust in the screening box.

[0005] Therefore, a screening machine for organic fertilizer production with a dust removal mechanism is proposed to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a screening machine for organic fertilizer production with a dust removal mechanism to solve the above problems, improving the problem that the positions of the air expansion hopper and the ventilation box are fixed. When the sieve mesh vibrates to screen the organic fertilizer, the dust will continuously change in the screening box, and it can only adsorb the dust from the same position, resulting in a reduced adsorption effect on the dust in the screening box.

[0007] The present utility model achieves the above object through the following technical solutions.

Under the action of the cam, while the sieve plate moves up and down reciprocally to screen the fertilizer, it drives the rack to move up and down reciprocally synchronously, and under the action of the rack and the gear, it is beneficial to drive the horizontal pipe and the circular pipes to rotate reciprocally with the center point of the gear as the rotation center point, so that the positions of the multiple circular pipes continuously change during the process of adsorbing dust in the screening box, which is beneficial to adsorbing dust inside the screening box from different directions and positions, thereby improving the dust removal effect of the screening box.

[0009] Preferably, the other end of the circular pipe is fixedly connected with a protective cover, and a filter plate is fixedly connected to the inner wall of the protective cover.

[0010] Preferably, an included angle is formed between the other end of the protective cover and the horizontal plane, and the filter plate is inclined.

Detailed Embodiment

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0023] During specific implementation: As Figures 1-4 shown, a screening machine for organic fertilizer production with a dust removal mechanism includes: a screening box 1, a sieve plate 2 is slidably connected to the inner wall of the screening box 1, and a dust removal device 3 is arranged inside the screening box 1; wherein, the dust removal device 3 includes a treatment box 301 fixedly connected to one side of the screening box 1, a blower 302 is installed at the top end of the treatment box 301, a dust suction pipe 303 is arranged inside the treatment box 301, one end of the dust suction pipe 303 penetrates into the screening box 1 and is fixedly connected to a connecting pipe 306, a gear 304 is rotatably connected to the front end of the screening box 1, one end of the gear 304 penetrates into the screening box 1 and is fixedly connected to a horizontal pipe 305, the other end of the connecting pipe 306 is communicated with the horizontal pipe 305, a series of equally distributed circular pipes 307 are fixedly connected to the surface of the horizontal pipe 305, and a driving assembly 308 is arranged at the bottom end of the sieve plate 2.

[0024] A feed inlet is arranged at the top end of the screening box 1, and a discharge outlet is arranged at the bottom end. When screening the organic fertilizer, the fertilizer is poured from the feed inlet, and the fertilizer will fall onto the sieve plate 2 for screening. One end of the sieve plate 2 penetrates out of the screening box 1. When the sieve plate 2 screens the fertilizer, the fertilizer smaller than the mesh diameter of the sieve plate 2 will pass through the sieve plate 2 and be discharged from the discharge outlet at the bottom end of the screening box 1, and the fertilizer larger than the mesh diameter of the sieve plate 2 will be discharged outwards from the top end of the sieve plate 2 during the screening process.

[0025] When screening the fertilizer, start the blower 302 in the dust removal device 3, and use the blower 302 to discharge the air in the treatment box 301 outwards, so that a negative pressure is formed in the treatment box 301. At this time, the dust suction pipe 303, the connecting pipe 306, the horizontal pipe 305 and the circular pipes 307 will adsorb the dust generated during screening. In the initial state of the device, the horizontal pipe 305 is inclined.

[0026] As Figure 2 and Figure 3As shown in the figure, the driving component 308 includes a motor 3081 fixedly connected to the front end of the screening box 1. The output shaft of the motor 3081 penetrates into the interior of the screening box 1 and is fixedly connected with a cam 3082. The bottom end of the sieve plate 2 is attached to the surface of the cam 3082. Both sides of the sieve plate 2 are fixedly connected with sliders 3083. The surface of the sliders 3083 is slidably connected with the inner wall of the screening box 1. The other side of one of the sliders 3083 penetrates out of the screening box 1 and is fixedly connected with a mounting block 3084. The top end of the mounting block 3084 is fixedly connected with a rack 3085. The surface of the rack 3085 is meshed with the surface of the gear 304.

[0027] When screening the organic fertilizer, the motor 3081 is started through the controller. The output shaft of the motor 3081 drives the cam 3082 to rotate. When the cam 3082 rotates from the lowest point to the highest point and contacts the bottom end of the sieve plate 2, the cam 3082 will push the sieve plate 2 to move upward. When the cam 3082 rotates from the highest point to the lowest point and contacts the bottom end of the sieve plate 2, under the action of the self-gravity of the fertilizer above the sieve plate 2, the sieve plate 2 will be driven to automatically reset, so that the bottom end of the sieve plate 2 is always attached to the surface of the cam 3082. Therefore, when the cam 3082 continuously rotates, the sieve plate 2 will move up and down reciprocally to screen the fertilizer.

[0028] When the sieve plate 2 moves upward, it will drive the slider 3083 to move upward synchronously. One of the sliders 3083 will push the rack 3085 to move upward synchronously through the mounting block 3084. When the rack 3085 moves upward, it will cause the gear 304 to rotate. When the gear 304 rotates, it will drive the cross tube 305 to rotate around the center point of the gear 304, so that the cross tube 305 drives the round tube 307 to rotate. When the sieve plate 2 moves downward to reset, it will drive the slider 3083, the mounting block 3084 and the rack 3085 to reset at the same time, and drive the cross tube 305 to reset through the gear 304. Therefore, during the up and down reciprocating movement of the sieve plate 2, under the action of the rack 3085 and the gear 304, the cross tube 305 drives a plurality of round tubes 307 to rotate reciprocally. During the reciprocating rotation of the plurality of round tubes 307, dust inside the screening box 1 will be adsorbed from different directions.

[0029] As Figure 4 shown, the other end of the round tube 307 is fixedly connected with a protective cover 3071. The inner wall of the protective cover 3071 is fixedly connected with a filter plate 3072. The other end of the protective cover 3071 forms an angle with the horizontal plane, and the filter plate 3072 is inclined. The overall shape of the protective cover 3071 is trumpet-shaped. When the round tube 307 adsorbs the dust inside the screening box 1, the dust will pass through the filter plate 3072, the protective cover 3071 in sequence and enter the round tube 307.

[0030] As Figure 3As shown in the figure, both sides of the top end of the sieve plate 2 are fixedly connected with protective plates 3086, and one side of the protective plate 3086 is attached to the inner wall of the screening box 1. The inner wall of the screening box 1 is provided with a chute that matches the slider 3083, and the position of the protective plate 3086 corresponds to the position of the chute.

[0031] As Figure 3 and Figure 4 shown, the connecting pipe 306 is set as a flexible pipe. The connecting pipe 306 can be deformed.

[0032] As Figure 2 shown, the inside of the treatment box 301 is filled with an aqueous solution. When adsorbing the dust in the screening box 1, the dust will pass through the round pipe 307, the horizontal pipe 305, the connecting pipe 306 and the dust suction pipe 303 in sequence and enter the treatment box 301 to be mixed with the aqueous solution.

[0033] When the present utility model is in use, when screening organic fertilizer, the fertilizer is poured onto the sieve plate 2, and the motor 3081 is started through the controller to drive the cam 3082 to rotate. At this time, under the action of the self-gravity of the fertilizer above the sieve plate 2, when the cam 3082 continuously rotates, the sieve plate 2 will move up and down reciprocally to screen the fertilizer. At this time, the fan 302 in the dust removal device 3 is started, and the air in the treatment box 301 is exhausted outwards by the fan 302, so that a negative pressure is formed in the treatment box 301. At this time, the dust suction pipe 303, the connecting pipe 306, the horizontal pipe 305 and the round pipe 307 will adsorb the dust generated during screening, and the adsorbed dust will enter the treatment box 301 to be mixed with the aqueous solution. At the same time, when the sieve plate 2 moves up and down reciprocally to screen the fertilizer, under the action of the slider 3083 and the mounting block 3084, the rack 3085 will be driven to move up and down reciprocally synchronously. When the rack 3085 moves up and down reciprocally, the gear 304 will be driven to rotate reciprocally. At this time, the gear 304 will drive the horizontal pipe 305 to rotate reciprocally with the center point of the gear 304 as the rotation center point, so that the horizontal pipe 305 drives a plurality of round pipes 307 to rotate reciprocally. During the reciprocal rotation of the plurality of round pipes 307, the dust inside the screening box 1 will be adsorbed from different directions, thereby improving the removal effect of the dust in the screening box 1.

[0034] In addition, it should be understood that although this specification is described according to the embodiments, not each embodiment only contains an independent technical solution. The narrative way of this 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.
