Description

Technical Field

[0001] The utility model relates to the technical field of aquatic feed production equipment, in particular to a pelletizing machine for aquatic feed production. Background Art

[0002] Feed pelletizing machine is a feed pelletizing equipment, which is a feed processing machine that directly presses pellets from crushed materials such as corn, soybean meal, straw, grass, rice husk, etc. It is now widely used in large, medium and small aquaculture, aquatic feed processing plants, livestock farms, aquaculture farms and other breeding industries, greatly facilitating the feeding and feeding operations of breeders.

[0003] An existing Chinese patent (publication number: CN218043700U) discloses a pelletizing device for fermented feed for aquatic products, comprising a feed pelletizer body, a discharge guide plate fixedly mounted on one side of the top of the feed pelletizer body, a support box fixedly connected to one side of the bottom of the feed pelletizer body, a collection box clamped inside the support box, and a limiting mechanism provided between one side of the collection box and one side of the support box.

[0004] During use, the pelletizing device for fermented aquatic feed disclosed above filters the particles through the provided filter screen. However, the mesh diameter cannot be adjusted during the filtration process, which means that it is inconvenient to filter feed particles of different sizes. Moreover, during the filtration process, it is impossible to dynamically adjust the temperature and wind speed during the drying process according to the size of the particles. In the feed pelletizing process, drying is an important step, and its effect directly affects the quality and shelf life of the feed. Feed particles of different sizes have different characteristics such as their surface area, internal structure, and moisture distribution, and therefore have different requirements for drying temperature and wind speed. Large-particle feed usually requires higher temperature and stronger wind speed to ensure that the internal moisture can be fully evaporated, while small-particle feed may be unevenly dried due to excessively high temperature or excessively strong wind speed, with the surface being overly dry or even burnt, and the drying efficiency being low, thereby affecting the formation and quality of the feed. Utility Model Content

[0005] The purpose of the utility model is to provide a pelletizing machine for producing aquatic feed, so as to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the utility model provides an aquatic feed production pelletizer, comprising a mounting base, a pelletizer body arranged on the top of the mounting base, and a drying box, including:

[0007] The first installation frame is connected to the drying box, and two filter screens are arranged horizontally and slide horizontally therein. When the two filter screens slide relative to or opposite to each other, the overlapping area of ​​the filter holes is expanded or reduced;

[0008] A driving gear is coaxially arranged with a driving shaft that drives the filter to slide, and an adjusting rack is meshedly connected to one side of the driving gear;

[0009] The temperature control knob and the wind control knob are respectively rotatably connected to the side of the drying box away from its feed end and are arranged in the same row. The adjustment rack is located between the temperature control knob and the wind control knob, and its two sides respectively conflict with the outer surfaces of the temperature control knob and the wind control knob.

[0010] Furthermore, the drying box is also provided with a wind angle adjustment component, including:

[0011] Six guide plates are connected to the drying box in a linear array with equal spacing along the length of the drying box;

[0012] A transmission gear is coaxially arranged with a driving shaft that drives the filter screen to slide, and one side of the transmission gear is meshed with a driven rack;

[0013] The resistance slider is arranged above the driven rack and moves vertically synchronously with the driven rack;

[0014] Six mounting gears are rotatably arranged on the side of the drying box away from the feed end and are coaxially arranged with the guide plate. The mounting gears are meshed with mounting racks.

[0015] The wedge block is connected to the mounting rack on one side close to the mounting gear and is located above the abutment slider. When the abutment slider moves vertically upward along the height direction of the drying box, it abuts against the wedge block, driving the mounting rack to slide horizontally.

[0016] Furthermore, the drying box is connected to a second mounting frame on a side away from its feed end, and the mounting rack is connected to a first guide rod on a side away from the wedge block. The first guide rod is slidably connected to the second mounting frame, and a return spring is sleeved on the first guide rod. One end of the return spring is connected to the second mounting frame, and the other end is connected to the mounting rack.

[0017] Furthermore, a first limiting block is connected to the top of the mounting rack, the first limiting block is slidably connected to the second mounting frame, and the second mounting frame is provided with a sliding groove adapted to the first limiting block.

[0018] Furthermore, one end of the drive shaft is connected to a force disk, and the side of the drying box away from its feed end is connected to a mounting plate, a transmission bolt is threadedly connected to the mounting plate, and the other end of the transmission bolt is rotatably connected to a limiting ring for limiting the force disk.

[0019] Furthermore, a second guide rod is connected to the bottom of the limiting ring, and the second guide rod is slidably connected to the mounting plate.

[0020] Furthermore, an adjusting gear is rotatably connected in the first mounting frame, and sliding racks are meshed and connected on both sides of the adjusting gear. The side of the sliding rack away from the inner wall of the mounting frame is connected to the filter screen, and a rotating shaft is connected to the adjusting gear, and the other end of the rotating shaft is interconnected with the drive shaft.

[0021] Furthermore, the drying box is connected to a first fixed block on a side away from its feed end, the driven rack is connected to a second limit block on a side away from the transmission gear, the second limit block is slidably connected to one side of the first fixed block, and the first fixed block is provided with a limit groove adapted to the second limit block.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. The drive shaft links the filter screen with the temperature and air control knobs, which can flexibly adjust the filter aperture and drying effect according to the particle size to meet the production needs of different aquatic feeds. The temperature is increased and the air flow is increased for large particles, while the speed is reduced and the air flow is reduced for small particles. This is conducive to uniform drying of the particles inside and outside, avoiding overheating or blowing away, improving drying efficiency, and helping to improve feed formation and quality.

[0024] 2. The angle of the guide plate is changed synchronously according to the filter mesh aperture adjustment to adapt the hot air flow direction to the size of the feed particles. It effectively gathers heat for large particles and blows evenly and slowly for small particles, ensuring the drying uniformity and effect. At the same time, this setting can easily cope with the production of feeds with different particle sizes without the need for complicated manual adjustment of the air path.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] See also Figure 1-9 The utility model provides a technical solution: a pelletizer for aquatic feed production, comprising a mounting base 1, a pelletizer body 2 arranged on the top of the mounting base 1, and a drying box 3, including:

[0037] The first mounting frame 401 is connected to the drying box 3 and has two filter screens 402 arranged in parallel and arranged therein. When the two filter screens 402 slide toward or away from each other, the overlapping area of ​​the filter holes expands or shrinks.

[0038] The driving gear 403 is coaxially arranged with the driving shaft that drives the filter screen 402 to slide, and one side of the driving gear 403 is meshedly connected with the adjustment rack 404;

[0039] The temperature control knob 405 and the wind control knob are respectively rotatably connected to the side of the drying box 3 away from its feed end and are arranged in the same line. The adjustment rack 404 is located between the temperature control knob 405 and the wind control knob, and its two sides respectively conflict with the outer surfaces of the temperature control knob 405 and the wind control knob.

[0040] It should be noted that an exhaust fan can be connected to the top of the drying box 3, and a heating resistance wire is connected inside the drying box 3 (not shown in the figure). The heating resistance wire generates heat, and then the exhaust fan generates wind force to act on the heating resistance wire, blowing the heat to the pellet feed produced in the drying box 3 for drying. This is a prior art, so no further explanation will be given here. At the same time, a feed port is also provided on one side of the drying box 3, which corresponds to the discharge end of the granulator body 2.

[0041] Preferably, one side of the adjustment rack 404 is connected to a third limiting block 18 , one side of the drying box 3 is connected to a second fixing block 17 , and the third limiting block 18 is slidably connected to the second fixing block 17 .

[0042] It should be further explained that for large-particle aquatic feed, the initial temperature adjustment interval is set to [60°C, 80°C]. Within this range, when the aperture of the filter 402 is adjusted to be suitable for large particles, the temperature control knob 405 can adjust the power of the heating resistance wire to raise the temperature in the drying box to a higher value in the interval, ensuring that the water inside the large-particle feed can be fully evaporated; for small-particle aquatic feed, the temperature adjustment interval is set to [40°C, 60°C]. When the aperture of the filter 402 is adjusted to be suitable for small particles, the temperature control knob 405 adjusts the power of the heating resistance wire to keep the temperature at a lower value in the interval, avoiding the small-particle feed from being evaporated due to high temperature. For large-particle aquatic feed, the wind control knob is connected to the exhaust fan, and the wind adjustment range can be set to [800rpm, 1200rpm] (rpm represents the fan speed). When the aperture of the filter 402 is adjusted to a larger value, the wind control knob increases the fan speed to a higher value in the range to ensure effective circulation of hot air around the large-particle feed; for small-particle aquatic feed, the wind adjustment range is set to [400rpm, 800rpm]. When the aperture of the filter 402 is adjusted to a smaller value, the wind control knob reduces the fan speed to a lower value in the range to prevent small particles from being blown away by strong wind or unevenly distributed in the drying equipment.

[0043] In specific implementation, the two filter screens 402 are pushed to slide relative to each other by rotating the drive shaft, at which time the overlapping area of the filter holes gradually expands; the two filter screens 402 are pulled to slide away from each other, at which time the overlapping area of the filter holes gradually shrinks. In this way, the effective filter hole diameter of the filter screen 402 can be accurately adjusted to adapt to the screening of aquatic feed particles of different particle sizes. During the rotation of the drive shaft, the drive gear 403 is driven to rotate, and then the adjusting rack 404 connected to one side of the drive gear 403 can be horizontally moved. Since the adjusting rack 404 is in contact with the outer surfaces of the temperature control knob 405 and the wind control knob on both sides, the movement of the adjusting rack 404 will drive the temperature control knob 405 and the wind control knob to rotate synchronously. When the temperature control knob 405 rotates, the power of the heating resistance wire will change, thereby adjusting the drying temperature. For example, when the adjusting rack 404 moves to the left to expand the overlapping area of the filter holes to adapt to large particles, the temperature control knob 405 will rotate to a higher temperature setting position accordingly, increasing the heating power to ensure that the moisture inside the large-particle feed can be fully evaporated. The wind control knob is connected to the air blower of the drying box 3, and the rotation of the wind control knob will change the speed of the air blower. When the adjusting rack 404 moves, the wind control knob rotates to adjust the working state of the air blower. For small-particle feed, when the overlapping area of the filter holes shrinks, the wind control knob can reduce the speed of the air blower to reduce the wind force, so as to avoid that the small particles are blown away or distributed unevenly in the drying equipment. For large-particle feed, the wind control knob can increase the speed of the air blower to increase the wind force, so as to ensure that the hot air around the large-particle feed can be effectively circulated, thereby improving the drying efficiency.

[0044] Reference Figure 7 The drying box 3 further comprises a wind angle adjusting assembly, which comprises:

[0045] Six guide plates 501 are linearly arrayed at equal intervals in the length direction of the drying box 3 and are rotationally connected in the drying box 3.

[0046] A transmission gear 502 is coaxially arranged with the drive shaft for driving the filter screen 402 to slide, and a driven rack 503 is connected to one side of the transmission gear 502.

[0047] A contact sliding block 504 is arranged above the driven rack 503 and moves vertically synchronously with the driven rack 503.

[0048] Six mounting gears 507 are rotationally arranged on the side of the drying box 3 away from the feeding end and are coaxially arranged with the guide plates 501, and a mounting rack 506 is connected to the mounting gears 507.

[0049] The wedge-shaped block 505 is connected to the mounting rack 506 near the side of the mounting gear 507 and is located above the abutting sliding block 504. When the abutting sliding block 504 moves vertically upward along the height direction of the drying box 3, it abuts against the wedge-shaped block 505, thereby driving the mounting rack 506 to slide horizontally.

[0050] Preferably, the number of the deflector plates 501 in the embodiment can be preferably six or eight as long as a better deflection effect can be provided. In the embodiment, the number of the deflector plates 501 is preferably six. In the specific production, the user can perform it according to the demand. Similarly, it can be known that the mounting gears 507 corresponding to the deflector plates 501 are also preferably six or eight as long as they can correspond to the number and position of the deflector plates 501 one by one during mounting.

[0051] In the specific implementation, when the aperture adjustment operation of the filter screen 402 is performed, the driving shaft for driving the filter screen 402 to slide rotates. Since the transmission gear 502 is coaxially arranged with the driving shaft, the rotation of the driving shaft drives the transmission gear 502 to rotate synchronously. The rotation of the transmission gear 502 causes the driven rack 503 engaged with the transmission gear 502 to move vertically. The abutting sliding block 504 connected above the driven rack 503 moves vertically together with the driven rack 503. When the abutting sliding block 504 moves vertically to a specific position, it abuts against the wedge-shaped block 505. After the abutting sliding block 504 abuts against the wedge-shaped block 505, since the wedge-shaped block 505 is connected to the mounting rack 506, the mounting rack 506 is pushed to slide horizontally. The horizontal sliding of the mounting rack 506 drives the mounting gear 507 engaged with the mounting rack 506 to rotate. The rotation of the mounting gear 507 causes the deflector plate 501 to rotate in the drying box 3. When the aperture of the filter screen 402 is adjusted to be large to adapt to the large-particle feed, the rotation of the driving shaft causes the deflector plate 501 to rotate to a suitable angle, so that the hot air is more effectively guided to the area of the large-particle feed, thereby enhancing the drying effect on the large-particle feed. When the aperture of the filter screen 402 is adjusted to be small, the deflector plate 501 is also rotated to an angle suitable for small-particle feed, thereby avoiding that the small-particle feed is directly blown away by the hot air or is unevenly distributed in the drying box 3, so as to improve the efficiency and quality of the entire drying process.

[0052] Reference Figure 9 The second mounting frame 6 is connected to the side of the drying box 3 away from the feeding end. The first guide rod 7 is connected to the side of the mounting rack 506 away from the wedge-shaped block 505. The first guide rod 7 is slidingly connected to the second mounting frame 6. The reset spring 8 is sleeved on the first guide rod 7. One end of the reset spring 8 is connected to the second mounting frame 6, and the other end is connected to the mounting rack 506.

[0053] In the specific implementation, the first guide rod 7 is arranged to limit and guide the sliding of the mounting rack 506, thereby further improving the stability of the mounting rack 506 during the sliding process. The reset spring 8 is arranged to facilitate the reset of the mounting rack 506 to the initial position.

[0054] refer to Figure 8 The top of the mounting rack 506 is connected with a first limiting block 9 , the first limiting block 9 is slidably connected to the second mounting frame 6 , and the second mounting frame 6 is provided with a sliding groove adapted to the first limiting block 9 .

[0055] During specific implementation, the first limiting block 9 can limit and guide the sliding of the mounting rack 506 .

[0056] refer to Figure 8 One end of the drive shaft is connected to a force disc 10, and the side of the drying box 3 away from its feed end is connected to a mounting plate 14. A transmission bolt 12 is threadedly connected to the mounting plate 14, and the other end of the transmission bolt 12 is rotatably connected to a limiting ring 11 that limits the force disc 10.

[0057] During specific implementation, the force disc 10 is convenient for rotating the drive shaft to adjust the operation of the upper component, and the limiting ring 11 is convenient for limiting the force disc 10, thereby avoiding position displacement of the force disc 10 after the adjustment is completed. By rotating the transmission bolt 12, the limiting ring 11 can be driven to move vertically to limit the force disc 10.

[0058] refer to Figure 8 The bottom of the limiting ring 11 is connected to a second guide rod 13 , and the second guide rod 13 is slidably connected to the mounting plate 14 .

[0059] During specific implementation, the second guide rod 13 is provided to limit and guide the sliding of the limiting ring 11, thereby further improving the stability of the limiting ring 11 during the sliding process.

[0060] refer to Figure 6 An adjusting gear 1901 is rotatably connected in the first mounting frame 401, and sliding racks 1902 are meshed and connected on both sides of the adjusting gear 1901. The side of the sliding rack 1902 away from the inner wall of the mounting frame 401 is connected to the filter screen 402, and a rotating shaft 1903 is connected to the adjusting gear 1901, and the other end of the rotating shaft 1903 is interconnected with the drive shaft.

[0061] During specific implementation, the rotating adjustment gear 1901 can drive the two sliding racks 1902 to move relative to or away from each other, thereby adjusting the overlapping area of ​​the two filter screens 402.

[0062] refer to Figure 7 and Figure 8 The drying box 3 is connected to a first fixed block 15 on the side away from its feed end, and the driven rack 503 is connected to a second limit block 16 on the side away from the transmission gear 502. The second limit block 16 is slidably connected to one side of the first fixed block 15, and the first fixed block 15 is provided with a limit groove adapted to the second limit block 16.

[0063] During specific implementation, the second limiting block 16 can limit and guide the sliding of the driven rack 503, further improving the stability of the driven rack 503 during the sliding process.

[0064] Working principle: By rotating the drive shaft, the two filter screens 402 are pushed to slide relative to each other, at which time the overlapping area of ​​their filter holes gradually expands; by pulling the two filter screens 402 to slide in opposite directions, the overlapping area of ​​the filter holes gradually shrinks. In this way, the effective filter aperture of the filter screen 402 can be accurately adjusted to adapt to the screening of aquatic feed particles with different particle size requirements. In the process of rotating the drive shaft, the drive gear 403 can be driven to rotate, and then the adjustment rack 404 engaged on one side of the drive gear 403 can be moved horizontally. Since its two sides respectively conflict with the outer surfaces of the temperature control knob 405 and the wind control knob, the movement of the adjustment rack 404 will drive the temperature control knob 405 and the wind control knob to rotate synchronously. When the temperature control knob 405 is rotated, the power of the heating resistor wire will be changed, thereby achieving the adjustment of the drying temperature. For example, when the adjustment rack 404 is moved to the left to expand the filter hole overlap area to suit large particles, the temperature control knob 405 will be rotated to a higher temperature setting position accordingly, increasing the heating power to ensure that the moisture inside the large particle feed can be fully evaporated. The wind control knob is connected to the exhaust fan of the drying box 3, and its rotation will change the speed of the exhaust fan. When the adjustment rack 404 moves, the wind control knob is rotated to adjust the working state of the fan. For example, for small particle feed, when the filter hole overlap area is reduced, the wind control knob may reduce the fan speed and reduce the wind force to prevent the small particles from being blown away by strong wind or unevenly distributed in the drying equipment; for large particle feed, the wind control knob will increase the fan speed and increase the wind force to ensure that the hot air around the large particle feed can effectively circulate, thereby improving the drying efficiency;

[0065] When the aperture of the filter 402 is adjusted, the drive shaft that drives the filter 402 to slide rotates. Since the transmission gear 502 is coaxially arranged with the drive shaft, the rotation of the drive shaft drives the transmission gear 502 to rotate synchronously. The rotation of the transmission gear 502 causes the driven rack 503 meshing with it to move vertically. The interference slider 504 connected above the driven rack 503 moves vertically along with the driven rack 503. When the interference slider 504 moves vertically to a specific position, it will conflict with the wedge block 505. After the interference slider 504 conflicts with the wedge block 505, since the wedge block 505 is connected to the mounting rack 506, it will push the mounting rack 506 to slide horizontally, and the horizontal movement of the mounting rack 506 will be reduced. The sliding movement drives the mounting gear 507 meshing therewith to rotate, and the rotation of the mounting gear 507 causes the guide plate 501 to rotate in the drying box 3. When the aperture of the filter 402 is increased to accommodate large-particle feed, the rotation of the drive shaft causes the guide plate 501 to rotate to a suitable angle, thereby more effectively directing the hot air to the area where the large-particle feed is located, thereby enhancing the drying effect on the large-particle feed. When the aperture of the filter 402 is decreased, the guide plate 501 will also rotate accordingly to an angle suitable for small-particle feed, thereby preventing the small-particle feed from being directly blown away by the hot air or being unevenly distributed in the drying box 3, thereby improving the efficiency and quality of the entire drying process.

[0066] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific 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 principles of the present invention should be included in the scope of protection of the present invention.
