Abstract
Description
Technical Field
[0001] This invention relates to the field of fish feed production technology, specifically to a conveying device for intelligent fish feed production. Background Technology
[0002] As an important part of agriculture-related industries, the aquaculture industry is developing rapidly towards large-scale and intelligent development. Among them, fish feed production and processing plays an important role in the aquaculture industry. The demand for precision and efficiency in fish feed production and processing is increasing. In the intelligent production process of fish feed, the conveying and screening process is a key step in fish feed production, which can improve the particle purity, finished product quality and the smoothness of subsequent processing.
[0003] In existing fish feed conveying devices, when fish feed is discharged from the upper funnel and falls onto the conveyor, the height difference and collisions between particles cause different sizes of fish feed to produce corresponding particle fragments. These fragments adhere to the surface of the conveyor belt and are conveyed into the packaging bag along with the feed, resulting in a large amount of debris in the fish feed product. Traditional conveying devices lack a screening structure, making it difficult to screen the fish feed fragments simultaneously during the conveying process. Furthermore, when screening the residue mixed in with the fish feed, the different particle sizes of fish feed produce different amounts of fragments. When processing fish feed of different particle sizes, the screen aperture size may not be suitable, causing the residue to not flow out easily or to clog the screen aperture. This makes it difficult to adapt to the size of the fish feed particles. On the other hand, if the residue that accumulates and adheres to the surface of the existing conveyor device is not cleaned in time, it will further affect the subsequent packaging quality of the fish feed.
[0004] To address the aforementioned issues, innovative designs are urgently needed based on existing approaches. Summary of the Invention
[0005] The purpose of this invention is to provide a conveying device for intelligent production of fish feed, so as to solve the problems mentioned in the background. The technical solution of this invention addresses the problem that the existing technical solutions are too simplistic and provides a solution that is significantly different from the existing technology.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a conveying device for intelligent fish feed production, comprising a base, with support frames slidably mounted on the upper left and right ends of the base via electric push rods; transmission rollers rotatably mounted on the inner side of the support frames; an inner conveyor belt sleeved on the outer side of the two transmission rollers; an outer conveyor belt slidably meshing on the outer side of the inner conveyor belt; limit frames provided on the left and right outer sides of the outer conveyor belt; the lower ends of the two limit frames fixed to the left and right ends of the base; an inclined plate provided at the middle position above the crossbar of the base; connecting rod one rotatably connected to the left and right ends of the front side of the inclined plate via shafts; transverse sliding frames slidably connected to the left and right ends of the rear side of the inclined plate via shafts; connecting rod two slidably connected vertically to the outer sides of the two transverse sliding frames; the lower ends of connecting rod one and connecting rod two fixedly connected to the front and rear crossbars of the base; mounting frames provided on the left and right sides of the inclined plate; mounting frames fixed to the front and rear crossbars of the base; an oil assembly provided between the transmission rollers and connecting rod two; and a vibration assembly slidably mounted vertically on the upper end of the mounting frame.
[0007] Optionally, the mounting frame has grooves on both the front and rear sides, and a sliding plate is slidably installed in each of the two grooves. A cleaning roller is rotatably installed between the two sliding plates. The longer sliding plate on the front side is connected to the cleaning roller through a motor, and bristles are fixed on the outside of the cleaning roller.
[0008] Optionally, ring plates are fixed on the front and rear sides of the drive roller surface, the ring plates corresponding to the thickness of the inner conveyor belt, and the outer ring plates of the drive roller are used to limit the inner conveyor belt.
[0009] Optionally, the inner and outer conveyor belts are provided with screen holes arranged in an equidistant array on their upper surfaces. The screen holes on the inner and outer conveyor belts are staggered and interconnected. The inner conveyor belt is used to adjust the size of the screen hole connection position of the outer conveyor belt when it slides. The limiting frame is used to limit the movement of the outer conveyor belt.
[0010] Optionally, the oil assembly includes two oil tanks, which are symmetrically installed on the rear side of the machine base. A plug body is slidably installed in the inner cavity of each oil tank via a spring seal. The upper end of the plug body is connected to the rear shaft protrusion of the transmission roller via a wedge. An oil tank is connected to the inner cavity of each oil tank via two ports and hoses. Two oil tanks are respectively fixed inside the front and rear slide grooves. A plug body is slidably installed in the inner cavity of each oil tank via a spring seal. The upper end of the plug body is fixedly connected to the bottom of the slide plate. An oil tank is connected to the inner cavity of each oil tank via another port and hose. The oil tank is installed in the vertical opening at the upper end of the connecting rod. A plug body is slidably installed in the inner cavity of the oil tank via a spring seal. The upper end of the plug body is fixedly connected to the transverse slide frame.
[0011] Optionally, one side of the upper wedge of the two plug bodies is a sloping structure. The sloping structure of the wedge is used to slide against the rear end protrusion of the transmission roller. The wedge is used to adjust the position of the plug body in the inner cavity of the oil tank.
[0012] Optionally, the vibration assembly includes two push rods, both of which are vertically slidably mounted in the front and rear grooves at the upper end of the mounting frame via springs. A vibrating roller is rotatably mounted between the two push rods. Gears are fixed to the outer sides of the shafts at both ends of the vibrating roller. Racks are meshed with the outer sides of the two gears. The racks are fixed to one side wall of the groove at the upper end of the mounting frame. Cams are abutted to the lower ends of the two push rods. Both cams are mounted on the outer sides of the shafts at both ends of the cleaning roller.
[0013] Optionally, the surface of the vibrating roller is equipped with symmetrical, uneven, arc-shaped protrusions at equal angles, which abut against the inner conveyor belt.
[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention, through the coordination of a mounting frame, a sliding plate, and a cleaning roller, completes the roller cleaning of the outer conveyor belt surface. Then, through the linkage of the cam and the top rod in the vibration assembly, the vibrating roller rotates up and down, sliding against the inner conveyor belt to generate vibration. In conjunction with the staggered screen holes on the outer and inner conveyor belts, small particles or powders generated during the fish feed conveying process are screened. At the same time, the installation position of the inclined plate guides the small particles or powders to be discharged, thereby solving the problem of excessive fine powder in the fish feed conveying device when it is delivered to the packaging bag, and improving the fullness of the fish feed particles after packaging.
[0015] This invention uses an electric push rod to drive a support frame, which in turn moves a transmission roller. This allows for adjustment of the misalignment of the screen holes on the inner and outer conveyor belts. When the fish feed particles are small and the debris generated during transport is fine, the inner conveyor belt is moved backward to increase the misalignment of the screen holes and decrease the through-hole diameter, thus screening for fine powder residue. Furthermore, through the cooperation between the transmission roller, sliding plate, transverse slide, and oil assembly, the transmission roller moves backward, and the contact between the transmission roller and the first plug body transports the corresponding oil from oil tank one to oil tanks two and three. This causes the second plug body to move... As the sliding plate moves upward, the contact force between the brush on the cleaning roller surface and the outer conveyor belt is adjusted accordingly to achieve the corresponding cleaning force. At the same time, the three plugs drive the transverse slide frame upward, correspondingly adjusting the inclination of the inclined plate to facilitate the guidance and discharge of fine powder. Simultaneously, the upward adjustment of the cleaning roller position causes the cam to drive the contact rod during rotation, resulting in a greater intermittent contact with the inner conveyor belt within the mounting bracket groove. This increases the vibration effect on the inner conveyor belt, allowing fine powder to quickly pass through the sieve holes and further improving the adaptive adjustment capability of the conveying equipment in cleaning and screening different types of fish feed.

[0018] To further illustrate the technical means and effects adopted by the present invention in order to achieve the intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structures, features and effects of the present invention.
[0019] Example 1 Please see Figures 1 to 11This invention provides a technical solution: a conveying device for intelligent fish feed production, comprising a base 1, with support frames 3 slidably mounted on the upper left and right ends of the base 1 via electric push rods 2. Drive rollers 4 are rotatably mounted inside the support frames 3. Inner conveyor belts 42 are sleeved on the outer sides of the two drive rollers 4. Ring plates are fixed on the front and rear sides of the surface of the drive rollers 4, the thickness of which corresponds to that of the inner conveyor belt 42. The outer ring plates of the drive rollers 4 are used to limit the movement of the inner conveyor belt 42. An outer conveyor belt 41 is slidably fitted on the outer side of the inner conveyor belt 42. Limiting frames 15 are provided on the left and right outer sides of the outer conveyor belt 41, with the lower ends of the two limiting frames 15 fixed to the left and right ends of the base 1. The upper surfaces of the inner conveyor belt 42 and the outer conveyor belt 41 are equal. The array has screen holes, and the screen holes on the inner conveyor belt 42 and the outer conveyor belt 41 are staggered and connected. When the inner conveyor belt 42 slides, it is used to adjust the size of the screen hole connection position of the outer conveyor belt 41. The limiting frame 15 is used to limit the outer conveyor belt 41. An inclined plate 6 is set at the middle position above the crossbar of the machine base 1. The left and right ends of the front side of the inclined plate 6 are rotatably connected to the connecting rod 5 through the shaft. The left and right ends of the rear side of the inclined plate 6 are laterally slidably connected to the horizontal slide frame 8 through the shaft. The two horizontal slide frames 8 are vertically slidably connected to the outer side of the two horizontal slide frames 8. The lower ends of the connecting rod 5 and the connecting rod 7 are fixedly connected to the front and rear crossbars of the machine base 1. Mounting frames 9 are set on the left and right sides of the inclined plate 6. The mounting frames 9 are fixed to the front of the machine base 1. On the rear crossbar, the mounting bracket 9 has sliding grooves 10 on both the front and rear sides. Slide plates 11 are slidably installed in each of the two grooves 10. A cleaning roller 12 is rotatably installed between the two slide plates 11. The longer front slide plate 11 is connected to the cleaning roller 12 via a motor. Brush bristles are fixed to the outside of the cleaning roller 12. An oil assembly is provided between the transmission roller 4 and the connecting rod 7. The oil assembly includes two oil tanks 141, symmetrically installed on the rear side of the base 1. A plug 142 is slidably installed inside the oil tank 141 via a spring seal. The upper end of the plug 142 is connected to the rear shaft protrusion of the transmission roller 4 via a wedge. One side of the wedge at the upper end of the two plugs 142 has a sloping structure. The sloping structure of the wedge is used for… The wedge block is used to adjust the position of the plug body 142 in the inner cavity of the oil tank 141. The inner cavity of the oil tank 141 is connected to the oil tank 2 143 through two ports and hoses. The two oil tanks 2 143 are respectively fixed inside the front and rear slide grooves 10. The plug body 2 144 is slidably installed in the inner cavity of the oil tank 2 143 through a spring seal. The upper end of the plug body 2 144 is fixedly connected to the bottom of the slide plate 11. The inner cavity of the oil tank 141 is connected to the oil tank 3 145 through another port and hose. The oil tank 3 145 is installed in the vertical opening at the upper end of the connecting rod 2 7. The plug body 3 146 is slidably installed in the oil tank 3 145 through a spring seal. The upper end of the plug body 3 146 is fixedly connected to the transverse slide frame 8.
[0020] Two sets of symmetrical support frames 3 are slidably mounted on both ends of the machine base 1. Drive rollers 4 are mounted on the support frames 3 and are driven to rotate by a motor. The drive rollers 4 drive the inner conveyor belt 42. Both the inner and outer conveyor belts 41 have teeth on their edges, achieving synchronous rotation through tooth meshing. During sieving, depending on the size of the fish feed particles, mixed debris and powder can be sieved through the screen holes on the surfaces of the inner and outer conveyor belts 41. When the debris and powder are fine, the electric push rod 2 pushes the support frames 3 to move rearwards from the machine base 1, and the drive rollers 4 follow suit. The support frame 3 moves synchronously, causing the inner conveyor belt 42 to move backward, while the outer conveyor belt 41 remains fixed under the limit of the limiting frame 15, causing the inner and outer conveyor belts 41 to be misaligned. The screen holes on the surface are thus misaligned. By adjusting the degree of misalignment, the through-hole diameter of the screen holes can be reduced to meet the screening requirements of finer powders, achieving the adaptation of conveying and screening different granular feeds. When the support frame 3 drives the drive roller 4 to move, the protrusion on one end of the shaft of the drive roller 4 will abut against the wedge at the upper end of the plug body 142, pushing the plug body 142. The oil tank 141 is displaced, and the oil is transported through a two-way pipe to four oil tanks 143. The oil drives the plug 144 in the oil tank 143 to move upward and contact the slide plate 11, thereby adjusting the height of the cleaning roller 12 installed on the slide plate 11 so that it fits the surface of the outer conveyor belt 41. One end of the cleaning roller 12 is driven by a motor, which is installed on the slide plate 11 through a fixing frame. The motor moves synchronously with the slide plate 11 and the cleaning roller 12, and the surface of the outer conveyor belt 41 is cleaned by rotation. At the same time, when the protrusion of the transmission roller 4 abuts against the plug body 142, it will also transport the oil in the oil tank 141 to the oil tank 3 145. The finer the slag powder, the greater the travel of the support frame 3, the more fully the abutment against the plug body 142, and the more oil output from the oil tank 141. The increased oil volume pushes the plug body 3 146 in the oil tank 3 145 to move upward, abutting the transverse slide frame 8 to move upward along the vertical opening at the upper end of the connecting rod 2 7, which raises the rear side of the inclined plate 6 and increases the inclination, making it easier for finer powder to be discharged from the machine base 1.
[0021] Example 2 Based on Example 1, please refer to Figures 1 to 11 A vibration assembly is vertically slidably mounted on the upper end of the mounting frame 9. The vibration assembly includes two push rods 131, which are vertically slidably mounted in the front and rear grooves on the upper end of the mounting frame 9 by means of springs. A vibrating roller 132 is rotatably mounted between the two push rods 131. The surface of the vibrating roller 132 is equipped with symmetrical arc-shaped protrusions of equal angles and uneven heights. The arc-shaped protrusions on the surface of the vibrating roller 132 abut against the inner conveyor belt 42. Gears 133 are fixed on the outer side of the shafts at both ends of the vibrating roller 132. A rack 134 is meshed with the outer side of the two gears 133. The rack 134 is fixed to one side wall of the groove at the upper end of the mounting frame 9. A cam 135 is abutted and connected to the lower end of the two push rods 131. The two cams 135 are mounted on the outer side of the shafts at both ends of the cleaning roller 12.
[0022] When the cleaning roller 12 rotates under the drive of the drive motor, the cam 135, which is coaxially mounted with it, rotates synchronously. Utilizing the spindle-shaped profile of the cam 135, it periodically pushes upward against the lower end of the push rod 131 during its rotation. As the cam 135 continues to rotate, the push rod 131 is intermittently pushed up, thereby driving the vibrating roller 132 connected to the upper end to perform a continuous and intermittent upward pushing action on the inner conveyor belt 42 above. When the protruding part of the cam 135 profile disengages from the push rod 131, the push rod 131 quickly falls back under the elastic restoring force of the spring, driving the vibrating roller 13... 2. Reset, and so on to form a stable vibration effect. At the same time, during the upward movement of the top rod 131, the gear 133 mounted on its side wall meshes with the fixedly arranged rack 134 to form a transmission. With the help of this meshing structure, the vibrating roller 132 can generate rotational motion while achieving up and down vibration. The surface of the vibrating roller 132 is specially provided with protrusions of varying heights. During the rotational vibration, these protrusions can form uneven impact force on the bottom surface of the conveyor belt, effectively improving the vibration effect. This can prevent fish feed particles from clogging the conveyor belt screen holes and accelerate the screening of crushed powder through the screen holes.
[0023] Working principle: When using this conveying device for intelligent fish feed production, firstly, two sets of left and right support frames 3 are slidably installed at both ends of the base 1. The transmission roller 4 is supported by the support frames 3. The transmission roller 4 is driven to rotate by the motor. The transmission roller 4 drives the inner conveyor belt 42 to rotate. The edges of the inner conveyor belt 42 and the outer conveyor belt 41 are both provided with teeth, so that the inner conveyor belt 42 and the outer conveyor belt 41 mesh with each other. When the inner conveyor belt 42 rotates, it drives the outer conveyor belt 41 to rotate synchronously. Based on the above, the particle size is distinguished according to the type of fish feed. The larger fish feed particles contain relatively large fragments and powder particles. These fragments and powder particles are screened out through the sieve holes on the surfaces of the inner conveyor belt 42 and the outer conveyor belt 41. When the fragments and powder particles are small, the electric push rod 2 pushes the support frame 3 to the rear of the machine base 1. When the support frame 3 moves backward, the transmission roller 4 also moves synchronously with the support frame 3. At this time, the inner conveyor belt 42 moves with the transmission roller 4, while the outer conveyor belt 41 remains stationary under the limiting action of the limiting frame 15, so that the inner conveyor belt 42 and the outer conveyor belt 41 are staggered. The sieve holes on the surfaces of the inner conveyor belt 42 and the outer conveyor belt 41 are also staggered. The degree of misalignment of the sieve holes on the surfaces of the inner conveyor belt 42 and the outer conveyor belt 41 is adjusted according to the size of the fragments and powder particles, so that the sieve holes on the surfaces of the inner conveyor belt 42 and the outer conveyor belt 41 are staggered, reducing the through-hole diameter of the sieve holes, making it easier for finer powder to pass through. The size of the sieve holes is adjusted to adapt to the conveying and screening of fish feed particles of different sizes. Based on the above, when the support frame 3 moves with the transmission roller 4, the protrusion on one end of the shaft of the transmission roller 4 will abut against the wedge at the upper end of the plug body 142. The plug body 142 moves in position within the oil tank 141, and the oil in the oil tank 141 is transported to the four oil tanks 2 143 through the two-way pipes at two of the interfaces. This causes the plug body 2 144 in the oil tank 2 143 to be adjusted upward and abut against the slide plate 11, thereby adjusting the height of the cleaning roller 12 installed on the slide plate 11, so that the cleaning roller 12 is close to the surface of the outer conveyor belt 41. At the same time, a motor is installed on one end of the shaft of the cleaning roller 12. The motor is installed on the slide plate 11 through a set of fixing brackets, and then moves together with the slide plate 11 and the cleaning roller 12, driving the cleaning roller 12 to rotate and clean the surface of the outer conveyor belt 41 after conveying. Based on the above, the motor drives the cleaning roller 12 to rotate, and the cam 135 rotates with the cleaning roller 12. When the cam 135 rotates, it will push against the top rod 131 upward. As the top rod 131 rotates with the cam 135, the vibrating roller 132 continuously and intermittently pushes the inner conveyor belt 42 upward, which in turn generates vibration in conjunction with the spring. When the top rod 131 moves upward, the meshing structure between the gear 133 and the rack 134 allows the vibrating roller 132 to rotate during vibration. The surface of the vibrating roller 132 is provided with protrusions of different heights to improve the vibration effect and help the conveyor belt to pass through the screen. Based on the above, when the support frame 3 moves with the transmission roller 4, the protrusion on one end of the shaft of the transmission roller 4 will abut against the wedge at the upper end of the plug body 142. The plug body 142 moves downward in the oil tank 141, and the oil in the oil tank 141 is transported to the oil tank 3 145 through one of the interfaces. When the powder is fine, the movement stroke of the support frame 3 is greater, which further abuts against the plug body 142, thereby increasing the output of oil in the oil tank 141. When the output in the oil tank 141 increases, the plug body 3 146 in the oil tank 3 145 abuts against the transverse slide 8. The transverse slide 8 moves upward along the vertical opening at the upper end of the connecting rod 2 7, and the rear side of the inclined plate 6 is further raised. The shafts on both sides of the inclined plate 6 are displaced in the transverse slide 8, which increases the inclination of the inclined plate 6, making it more convenient for the discharge of finer powder.
