Description

Technical Field

[0001] The invention relates to the technical field of organic fertilizer production, in particular to an organic fertilizer drum screening device. Background Art

[0002] Screening is an important step in the production of organic fertilizer. At present, the most commonly used one is the organic fertilizer screening machine. The equipment is mainly composed of a motor, a reducer, a roller device, a frame, a sealing cover, and an inlet and outlet. The roller device is installed on the frame at an angle. The motor is connected to the roller device through a coupling via a reducer to drive the roller device to rotate around its axis. When the material enters the roller device, the tilt and rotation of the roller device cause the material on the screen surface to flip and roll, allowing qualified materials to be discharged through the screen of the outer circle of the drum screen, and unqualified materials to be discharged through the end of the drum.

[0003] However, the current drum screen can only screen a single type of organic fertilizer, while manufacturers generally produce multiple types of organic fertilizers. To screen different types of organic fertilizers, either one type of organic fertilizer can be completely screened before the next type of organic fertilizer is screened, which has low screening efficiency, or multiple drum screens are prepared for screening separately, which increases costs.

[0016] The beneficial effects of the present invention are:

[0017] 1. The drum screen is divided into two parts by installing a partition, so that two kinds of organic fertilizers can be screened at the same time. A pair of semicircular discharge covers are respectively covered with half of the drum screen. The motor and the reducer drive the rotating shaft and the drum screen to rotate for screening. The materials screened out by the two kinds of organic fertilizers are poured into the corresponding receiving boxes through two staggered discharge pipes for collection, and the screening efficiency is high.

[0018] 2. By installing the first circular loading box, the second circular loading box, two loading hoppers and the opening and closing mechanism, the two loading hoppers can be filled with two different organic fertilizers, and the first circular loading box and the second circular loading box rotate together with the drum screen. When the lower feeding port is turned to the hopper mouth of the upper feeding hopper, the first magnetic block and the second magnetic block are magnetically attracted to each other, thereby limiting the rotation of the arc-shaped baffle plate. The lower feeding port is opened, and different organic fertilizers enter the first circular loading box and the second circular loading box respectively. The organic fertilizer in the first circular loading box is guided by the arc-shaped guide plate, and the organic fertilizer in the second circular loading box is guided by the arc-shaped guide plate and the connecting pipe therein, and finally enters the drum screen through the corresponding feed port. The lower feeding port is turned away from the upper feeding hopper, and the arc-shaped baffle plate is reset under the action of the spring, thereby realizing an intermittent feeding process.

[0019] 3. By installing a long and a short discharge hood, organic fertilizer with larger particles will eventually enter the discharge hood. When the drop port on the discharge hood turns downward, different types of materials fall into the corresponding receiving box through the staggered drop ports for collection.

[0020] 4. By installing the knocking mechanism, when half of the drum screen rotates to the top, the arc-shaped conductive sheet on the top of the rotating shaft contacts the conductive head, and it is intermittently energized through the pulse switch, and then the second spring at the inner end of the multiple knocking rods on the top of the rotating shaft is energized. The second spring is energized and contracts, and then the knocking rod is driven to move up quickly, knocking the top mesh surface, shaking off the particles blocked in the mesh holes on the top mesh surface, so as to avoid affecting the screening effect.

[0031] Reference Figure 1-7 A drum screening device for organic fertilizer comprises a base 1, support frames 2 are fixedly connected to both sides of the base 1, a drum screen 12 arranged obliquely is rotatably connected between the two support frames 2 via a rotating shaft 9, a reducer 5 and a motor 6 are installed on the right support frame 2, the input end and the output end of the reducer 5 are respectively connected to the motor 6 and the rotating shaft 9, the rotating shaft 9 extends into the drum screen 12 and is fixedly connected to a partition 14 which can divide the drum screen 12 into two, and the screening process of two kinds of organic fertilizers can be carried out at the same time, and the rotating shaft and the drum screen are driven by the motor and the reducer to rotate to screen the materials.

[0032] The feeding end of the drum screen 12 is fixedly connected with a first circular loading box 28 and a second circular loading box 20. The feeding end of the drum screen 12 is provided with two upper and lower feeding ports 17. The lower feeding port 17 is communicated with the first circular loading box 28, and the upper feeding port 17 is communicated with the second circular loading box 20 through a connecting pipe 18 that penetrates the first circular loading box 28. The bottom of the first circular loading box 28 and the top of the second circular loading box 20 are both fixedly connected with an arc-shaped guide plate 19. The arc-shaped guide plate 19 in the first circular loading box 28 is connected to the feeding port 17 below, and the arc-shaped guide plate 19 in the second circular loading box 20 is connected to the connecting pipe 18.

[0033] A discharge port 24 is provided at the top of the first circular loading box 28 and the bottom of the second circular loading box 20, and an opening and closing mechanism is installed in the discharge port 24. The opening and closing mechanism includes an arc groove 26 arranged in the first circular loading box 28 and the second circular loading box 20 and connected with the discharge port 24, and an arc-shaped baffle plate 23 extending into the discharge port 24 is elastically connected in the arc groove 26 by a first spring 27, and a first magnetic block 25 is embedded in the front end of the arc baffle plate 23, and a second magnetic block 22 cooperating with the first magnetic block 25 is embedded in the rear discharge port of the upper hopper 21. When the discharge port 24 is turned to the hopper mouth of the upper hopper, the first magnetic block 25 and the second magnetic block 22 at the front end of the arc baffle plate 23 are magnetically attracted to each other, thereby limiting the rotation of the arc baffle plate 23 and the discharge port 24 is opened.

[0034] Two upper hoppers 21 are fixedly connected to the top of the left support frame 2, and the lower feeding ports of the two upper hoppers 21 are respectively covered on the top of the first circular loading box 28 and the second circular loading box 20. The lower feeding ports of the two upper hoppers 21 are respectively adjacent to the top walls of the first circular loading box 28 and the second circular loading box 20, and the adjacent gap is smaller than the size of the organic fertilizer particles, so that the material will not leak during the rotation process.

[0035] A pair of upper and lower semicircular discharge covers 10 are also sleeved on the drum screen 12, and the side walls of the pair of semicircular discharge covers 10 are provided with staggered discharge pipes 11. A discharge mechanism is installed at the discharge end of the drum screen 12, and the discharge mechanism includes upper and lower discharge ports 16 and two discharge covers 7, one long and one short, arranged on the discharge end of the drum screen 12. The long discharge cover 7 is connected to the upper discharge port 16, and the short discharge cover 7 is connected to the lower discharge port 16. The bottoms of the two discharge covers 7 are provided with staggered discharge ports 8, and the discharge process is carried out when the discharge port 8 on the discharge cover 7 is turned to the bottom.

[0036] Two receiving boxes 4 corresponding to the two dropping openings 8 are placed on the base 1. Different types of materials fall into the corresponding receiving boxes 4 through the staggered dropping openings 8 for collection. Two receiving boxes 3 corresponding to the two dropping pipes 11 are also placed on the base 1. When the two staggered dropping pipes 11 are turned to the bottom, the two kinds of organic fertilizer particles can be poured into the corresponding receiving boxes 3 for collection.

[0037] In addition, a knocking mechanism is installed on a section of the rotating shaft 9 located in the drum screen 12, and the knocking mechanism includes a knocking component and a conductive component. The knocking component includes a plurality of staggered knocking rods 15 elastically installed on the top and bottom of the rotating shaft 9, and a plurality of circular cavities 29 are provided in the rotating shaft 9. The inner ends of the knocking rods 15 extend into the corresponding circular cavities 29 and are elastically connected to a second spring 30. The conductive component includes a through hole 13 provided on the right support frame 2 for the rotating shaft 9 to pass through, and a conductive head 31 is fixedly connected to the inner top of the through hole 13. The conductive head 31 is externally connected to a power supply and a pulse switch. Arc-shaped conductive sheets 32 cooperating with the conductive heads 31 are embedded on the upper and lower sides of the through section of the rotating shaft 9, and the upper arc-shaped conductive sheet 32 ​​is electrically connected to the second spring 30 at the inner ends of the plurality of knocking rods 15 at the top of the rotating shaft 9, and the lower arc-shaped conductive sheet 32 ​​is electrically connected to the second spring 30 at the inner ends of the plurality of knocking rods 15 at the bottom of the rotating shaft 9.

[0038] The two loading hoppers 21 are filled with two different organic fertilizers, the motor 6 is started, and the rotating shaft 9 and the drum screen 12 are driven to rotate through the reducer 5, and the first circular loading box 28 and the second circular loading box 20 rotate together with the drum screen 12. When the lower feeding port 24 rotates to the bucket mouth of the upper hopper, the first magnetic block 25 and the second magnetic block 22 at the front end of the arc-shaped baffle plate 23 are magnetically attracted to each other, thereby limiting the rotation of the arc-shaped baffle plate 23, and the lower feeding port 24 is opened, and different organic fertilizers enter the first circular loading box 28 and the second circular loading box 20 respectively. The organic fertilizer in the first circular loading box 28 is guided by the arc-shaped guide plate 19 therein, and the organic fertilizer in the second circular loading box 20 is guided by the arc-shaped guide plate 19 and the connecting pipe 18 therein, and finally enters the corresponding half drum screen 12 through the corresponding feeding port 17. The lower feeding port 24 rotates away from the upper hopper 21, and the arc-shaped baffle plate 23 is reset under the action of the first spring 27 after reaching the limit position, thereby realizing the intermittent feeding process of the two organic matters.

[0039] When the organic fertilizer rotates to the bottom, the smaller particles pass through the mesh surface at the bottom and continue to rotate. The two smaller organic fertilizer particles enter the corresponding semicircular feeding cover 10 respectively. When the two misplaced feeding pipes 11 rotate to the bottom, the two organic fertilizer particles can be poured into the corresponding receiving box 3 for collection.

[0040] When half of the drum screen 12 rotates to the upper side, the arc-shaped conductive sheet 32 ​​on the top of the rotating shaft 9 contacts the conductive head 31, and intermittently energizes it through the pulse switch, thereby energizing the second spring 30 at the inner end of the multiple knocking rods 15 on the top of the rotating shaft 9. The second spring 30 contracts when energized and resets when the power is cut off, thereby driving the multiple knocking rods 15 on the top to move reciprocally up and down, and then knock on the mesh surface on the top, shaking off the particles blocked in the mesh holes on the top mesh surface to avoid affecting the screening effect.

[0041] The organic fertilizer with larger particles finally enters two discharge covers 7, one long and one short. When the discharge opening 8 on the discharge cover 7 turns downward, the discharge process is carried out, and different types of materials fall into the corresponding receiving box 4 through the staggered discharge opening 8 for collection.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
