Description

Technical Field

[0001] This invention relates to the field of biological feed processing technology, specifically to a feeding device for the production of mixed biological feed pellets. Background Technology

[0002] Biological feed refers to feed products developed using feed ingredients and additives permitted by relevant national regulations through bioengineering technologies such as fermentation engineering, enzyme engineering, protein engineering, and genetic engineering. Biological feed can effectively improve the digestibility and absorption rate of animals, enhance their immune function, and promote animal growth. Currently, the production process of biological feed requires mixing raw materials to ensure nutritional balance.

[0003] Patent publication number CN216538198U relates to a premixing device for biological feed production, including a support base and a drive unit. The support base has a feed pipe at its top inlet. A through-hole in the middle of the top of the support base is rotatably connected to the support pipe via a bearing. A mixing funnel is located at the lower end of the support pipe. A stirring shaft is rotatably connected to the inside of the support pipe via a bearing. Both the upper and lower ends of the stirring shaft extend outside the support pipe. A stirring blade is located at the lower end of the stirring shaft. A collection funnel is located on the lower surface of the support base, and the mixing funnel and stirring blade are both located inside the collection funnel. The drive unit is located on the top front side of the support base. The upper ends of the support pipe and the stirring shaft are fixedly connected to the rear end of the drive unit. A control switch group is located on the left rear side of the top of the support base. The input end of the control switch group is electrically connected to an external power source. This premixing device for biological feed production has a good mixing effect, which helps to improve the production quality of biological feed.

[0004] In the aforementioned patent, the input end of the control switch group is electrically connected to an external power source. This premixing device for biological feed production has a good mixing effect, which helps to improve the production quality of biological feed. However, before the pelleted feed is poured into the feed inlet for mixing, it is difficult to squeeze and break up the clumps of feed in advance. When the clumps of feed enter the mixing box, it will cause uneven mixing of feed, resulting in feed waste and reducing the mixing effect. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a feeding device for the production of mixed biological feed pellets, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a feeding device for the production of biological feed pellets and mixed feed, including a mixing box, a No. 1 motor fixedly installed at the bottom of the mixing box, a bracket fixedly installed on the circumference of the mixing box, a discharge port fixedly penetrating the bottom of the mixing box, a feeding box fixedly installed at the top of the mixing box, a No. 1 drive shaft fixedly installed at the output end of the No. 1 motor, a No. 1 stirring rod fixedly installed on the circumference of the No. 1 drive shaft, and a dispersing device, a control device, and a mixing device; The dispersing device includes a second motor, a second drive shaft, a short rod, an arc-shaped strip, an arc-shaped block, a triangular block, and a filter plate. The second motor is fixedly installed on the right side of the feed box, the second drive shaft is fixedly installed at the output end of the second motor, the short rod is fixedly installed on the circumference of the second drive shaft, the arc-shaped strip is fixedly installed on the circumference of the second drive shaft, the arc-shaped block is fixedly installed on the inner wall of the feed box, the filter plate is slidably installed on the inner wall of the feed box, and the triangular block is slidably installed on the top of the filter plate. The rotation of the second drive shaft drives the short rod to rotate, and the short rod rotates and contacts the filter plate, squeezing the filter plate. The filter plate moves downward under pressure. When the filter plate moves downward, the triangular block will separate from the arc-shaped block, and the triangular block will be reset by the elastic force of the first spring.

[0007] According to the above technical solution, the top of the triangular block is an arc surface, a first spring is provided between the triangular block and the filter plate, and a second spring is provided between the filter plate and the feed box, so as to facilitate the movement of the triangular block and the reciprocating motion of the triangular block and the filter plate.

[0008] According to the above technical solution, the control device includes a first inclined panel, a rotating shaft, a second inclined panel, a first inclined rod, and a second inclined rod. The rotating shaft rotates through the left side of the feed box. The first inclined panel is fixedly installed on the circumferential surface of the rotating shaft, and the second inclined panel is fixedly installed on the inner wall of the feed box. The first inclined rod is fixedly installed on the circumferential surface of the rotating shaft, and the second inclined rod is fixedly installed on the circumferential surface of the second drive shaft. The rotation of the second drive shaft drives the second inclined rod to rotate. The second inclined rod rotates and contacts the first inclined rod, squeezing the first inclined rod. The first inclined rod rotates under the squeezing force.

[0009] According to the above technical solution, the first inclined panel is in contact with the second inclined panel, a spring is provided between the rotating shaft and the feed box, and the side of the second inclined rod away from the second transmission shaft is an arc surface, which facilitates the reciprocating motion of the first inclined panel and facilitates the second inclined rod to squeeze the first inclined rod.

[0010] According to the above technical solution, the control device further includes a T-shaped rack, a gear, a disc, a first ring, a second ring, and a fourth spring. The T-shaped rack is slidably mounted on the left outer wall of the feed box, the gear is fixedly mounted on the circumferential surface of the rotating shaft, and the T-shaped rack meshes with the gear. The disc is slidably mounted on the circumferential surface of the first transmission shaft, the first ring is fixedly mounted on the circumferential surface of the first transmission shaft, the second ring is fixedly mounted on the circumferential surface of the first transmission shaft, and the fourth spring is disposed between the second ring and the disc. The rotation of the gear drives the T-shaped rack to move downward, and the downward movement of the T-shaped rack compresses the disc. The disc is subjected to compressive force and moves downward, contacting the second ring.

[0011] According to the above technical solution, the disc has an arc-shaped hole and is located between the first ring and the second ring. The T-shaped rack contacts the disc, which facilitates the feed to fall more evenly into the mixing tank and improves the feed mixing quality.

[0012] According to the above technical solution, the mixing device includes a vertical rod, a horizontal rod, a third drive shaft, a pusher plate, an arc-shaped limiting strip, and a guide block. The horizontal rod is slidably mounted on the circumferential surface of the first drive shaft, the vertical rod is fixedly mounted on the top of the horizontal rod, the third drive shaft is rotatably mounted on the bottom of the horizontal rod, the pusher plate is rotatably mounted on the circumferential surface of the third drive shaft, the arc-shaped limiting strip is fixedly mounted on the circumferential surface of the third drive shaft, and the guide block is fixedly mounted on the top of the first stirring rod. A spiral groove is formed on the circumferential surface of the third drive shaft, and the bottom of the third drive shaft is threaded into the inside of the guide block. When the third drive shaft moves downward, the spiral groove on its surface slides downward inside the guide block. Under the guiding action, the third drive shaft rotates, and the pusher plate rotates as the third drive shaft rotates.

[0013] According to the above technical solution, the arc-shaped limiting strip contacts the bottom of the pusher plate, and the pusher plate and the No. 3 transmission shaft are directly equipped with a No. 3 spring to limit the pusher plate and prevent the pusher plate from rotating too much, which would affect the feed pushing effect.

[0014] This invention provides a feeding device for the production of mixed biological feed pellets, which has the following beneficial effects: (1) When the feed needs to be processed and stirred, the No. 2 motor starts and drives the No. 1 drive shaft and the arc strip to rotate, which breaks up the feed, making the feed more uniform and improving the mixing efficiency. At the same time, the No. 1 drive shaft rotates and drives the filter plate to move up and down. Qualified feed enters the mixing box through the filter plate, while unqualified feed stays on the top of the filter plate. The triangular block pushes and squeezes the feed, and the arc strip breaks up the unqualified feed, which improves the feed utilization rate and thus improves the feed mixing effect.

[0015] (2) In this invention, when qualified feed falls into the first inclined plate and the second inclined plate, the drive shaft rotates and drives the second inclined rod to rotate and contact the first inclined rod, thereby driving the first inclined plate to reciprocate, thus opening and closing the feed inlet, controlling the feed speed, preventing too much feed from entering the mixing box and affecting the mixing effect. At the same time, the disc rotates and vibrates, making the feed more evenly dispersed inside the mixing box, thus improving the feed mixing effect.

[0016] (3) In this invention, the disc moves up and down, which drives the No. 3 drive shaft to move up and down and rotate. The rotation of the No. 3 drive shaft drives the pusher plate to rotate, which stirs the feed, making the feed mix better and thus improving the mixing effect of the feed. At the same time, the pusher plate moves up and down, gradually driving the feed to move upward, avoiding uneven mixing of the feed at the bottom, causing stratification, resulting in uneven mixing and reducing the mixing effect of the feed.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-7 A feeding device for producing mixed biological feed pellets includes a mixing box 1, a No. 1 motor 2 fixedly installed at the bottom of the mixing box 1, a bracket 5 fixedly installed on the circumference of the mixing box 1, a discharge port 6 fixedly passing through the bottom of the mixing box 1, a feeding box 7 fixedly installed at the top of the mixing box 1, a No. 1 drive shaft 3 fixedly installed at the output end of the No. 1 motor 2, and a No. 1 stirring rod 4 fixedly installed on the circumference of the No. 1 drive shaft 3. It also includes a dispersing device, a control device and a mixing device. The dispersing device includes a second motor 81, a second drive shaft 82, a short rod 83, an arc-shaped strip 84, an arc-shaped block 85, a triangular block 86, and a filter plate 87. The second motor 81 is fixedly installed on the right side of the feed box 7, the second drive shaft 82 is fixedly installed at the output end of the second motor 81, the short rod 83 is fixedly installed on the circumference of the second drive shaft 82, the arc-shaped strip 84 is fixedly installed on the circumference of the second drive shaft 82, the arc-shaped block 85 is fixedly installed on the inner wall of the feed box 7, the filter plate 87 is slidably installed on the inner wall of the feed box 7, and the triangular block 86 is slidably installed on the top of the filter plate 87. Unqualified feed will remain on the top of the filter plate 87, the triangular block 86 will push and squeeze the unqualified feed, and the arc-shaped strip 84 will disperse the unqualified feed, thereby improving the feed utilization rate and improving the feed mixing effect.

[0021] The top of the triangular block 86 is an arc surface. A first spring is installed between the triangular block 86 and the filter plate 87, and a second spring is installed between the filter plate 87 and the feed box 7, which facilitates the movement of the triangular block 86 and the reciprocating motion of the triangular block 86 and the filter plate 87.

[0022] The control device includes a first inclined plate 91, a rotating shaft 92, a second inclined plate 93, a first inclined rod 94, and a second inclined rod 97. The rotating shaft 92 rotates through the left side of the feed box 7. The first inclined plate 91 is fixedly installed on the circumference of the rotating shaft 92. The second inclined plate 93 is fixedly installed on the inner wall of the feed box 7. The first inclined rod 94 is fixedly installed on the circumference of the rotating shaft 92. The second inclined rod 97 is fixedly installed on the circumference of the second drive shaft 82. The device controls the feed feeding speed and prevents too much feed from entering the mixing box 1, which would affect the mixing effect.

[0023] The first inclined plate 91 contacts the second inclined plate 93. A spring is provided between the rotating shaft 92 and the feed box 7. The side of the second inclined rod 97 away from the second transmission shaft 82 is an arc surface, which facilitates the reciprocating motion of the first inclined plate 91 and facilitates the second inclined rod 97 to squeeze the first inclined rod 94.

[0024] The control device also includes a T-shaped rack 95, a gear 96, a disc 98, a first ring 99, a second ring 910, and a fourth spring 911. The T-shaped rack 95 is slidably mounted on the left outer wall of the feed box 7. The gear 96 is fixedly mounted on the circumferential surface of the rotating shaft 92, and the T-shaped rack 95 meshes with the gear 96. The disc 98 is slidably mounted on the circumferential surface of the first transmission shaft 3. The first ring 99 is fixedly mounted on the circumferential surface of the first transmission shaft 3. The second ring 910 is fixedly mounted on the circumferential surface of the first transmission shaft 3. The fourth spring 911 is located between the second ring 910 and the disc 98, so that the feed is more evenly dispersed inside the mixing box 1, and the feed mixing effect is better improved.

[0025] The disc 98 has an arc-shaped hole and is located between the first ring 99 and the second ring 910. The T-shaped rack 95 contacts the disc 98, which facilitates the feed to fall more evenly into the mixing box 1 and improves the feed mixing quality.

[0026] The mixing device includes a vertical rod 101, a horizontal rod 102, a third drive shaft 103, a pusher plate 104, an arc-shaped limiting strip 105, and a guide block 106. The horizontal rod 102 is slidably mounted on the circumferential surface of the first drive shaft 3. The vertical rod 101 is fixedly mounted on the top of the horizontal rod 102. The third drive shaft 103 is rotatably mounted on the bottom of the horizontal rod 102. The pusher plate 104 is rotatably mounted on the circumferential surface of the third drive shaft 103. The arc-shaped limiting strip 105 is fixedly mounted on the circumferential surface of the third drive shaft 103. The guide block 106 is fixedly mounted on the top of the first stirring rod 4. The circumferential surface of the third drive shaft 103 has a spiral groove. The bottom of the third drive shaft 103 is threaded into the inside of the guide block 106 to stir the feed inside the mixing tank 1, so that the feed is better mixed, while avoiding uneven mixing of the feed at the bottom, which would cause stratification, resulting in uneven mixing and reduced feed mixing effect.

[0027] The arc-shaped limiting strip 105 contacts the bottom of the pusher plate 104. The pusher plate 104 and the third drive shaft 103 are directly connected by a third spring to limit the pusher plate 104 and prevent the pusher plate 104 from rotating too much, which would affect the feed pushing effect.

[0028] During operation: When feed processing and mixing are required, motor 2 starts, driving drive shaft 3 to rotate. Drive shaft 3 rotates, driving stirring rod 4 to rotate. Simultaneously, feed is poured into feed box 7. Qualified feed will fall through filter plate 87 between inclined plate 91 and inclined plate 93, while unqualified feed will remain on top of filter plate 87. At the same time, motor 81 starts, driving drive shaft 82 to rotate. Drive shaft 82 rotates, driving arc bar 84 to break up unqualified feed. Drive shaft 82 also rotates short rod 83. The rotating part contacts and squeezes the filter plate 87, causing it to move downwards under pressure. As the filter plate 87 moves downwards, the triangular block 86 disengages from the arc-shaped block 85. The triangular block 86 is reset by the force of the first spring. The filter plate 87 moves upwards by the force of the second spring. As the filter plate 87 moves upwards, the triangular block 86 contacts the arc-shaped block 85, which then squeezes the triangular block 86. The triangular block 86 moves under the squeezing force, pushing the unqualified feed towards the second drive shaft 82. This causes the arc-shaped strip 84 to break up the feed, thus improving the feed utilization rate.

[0029] The rotation of the second drive shaft 82 drives the second inclined rod 97 to rotate, which in turn contacts the first inclined rod 94 and compresses it. The first inclined rod 94 rotates under this pressure, which in turn drives the rotating shaft 92 to rotate. The rotating shaft 92 then drives the first inclined panel 91 to rotate, disengaging it from the second inclined panel 93 and opening the feed inlet, allowing feed to enter the mixing tank 1. Simultaneously, the pressure on the first inclined rod 94 drives the rotating shaft 92 to rotate, which in turn drives the gear 96 to rotate. The gear 96 then moves the T-shaped rack 95 downwards, compressing the disc 98. The disc 98 moves downwards under this pressure and contacts the second ring 910. When the second inclined rod 97 rotates to a side away from the first inclined rod 94, the first inclined rod 94 disengages from the second inclined rod 97. When the pressure is released upon contact, the first inclined rod 94 loses pressure, and the rotating shaft 92 rotates in the opposite direction due to the spring force. The rotation of the rotating shaft 92 in the opposite direction drives the first inclined rod 94 to reset. At the same time, the rotation of the rotating shaft 92 in the opposite direction drives the first inclined panel 91 to reset. The first inclined panel 91 then contacts the second inclined panel 93, thereby closing the feed inlet and controlling the feed feeding speed to prevent too much feed from entering at once, which would affect the mixing effect. At the same time, the rotation of the rotating shaft 92 in the opposite direction drives the gear 96 to rotate in the opposite direction. The rotation of the gear 96 in the opposite direction drives the T-shaped rack 95 to move upward. The T-shaped rack 95 moves upward and disengages from the disc 98. When the disc 98 disengages, it loses pressure and moves upward due to the spring force of the fourth spring 911, contacting the first ring 99 and generating vibration. The feed falls through the arc-shaped hole on the disc 98, so that the feed is evenly dispersed inside the mixing box 1.

[0030] When the disc 98 moves downward under pressure, it drives the vertical rod 101 downward. The downward movement of the vertical rod 101 drives the horizontal rod 102 downward. The downward movement of the horizontal rod 102 drives the third drive shaft 103 downward. When the third drive shaft 103 moves downward, the spiral groove on its surface slides downward inside the guide block 106. Under the guidance, the third drive shaft 103 rotates, causing the pusher plate 104 to rotate, which better mixes the feed and makes it more uniform. The downward movement of the third drive shaft 103 drives the pusher plate 104 downward. At the same time, the downward movement of the third drive shaft 103 drives the arc-shaped limiting strip 105 downward. When the pusher plate 104 moves downward, it is subjected to the extrusion force of the feed. The pusher plate 104 rotates in the direction of the third drive shaft 103, causing the pusher plate 104 to contract, reducing the resistance to the downward movement of the pusher plate 104, and thus reducing the downward movement of the feed pushed by the pusher plate 104. When disc 98 disengages from T-shaped rack 95, disc 98 moves upward due to the elastic force of spring 911. The upward movement of disc 98 drives vertical rod 101 to move upward, which in turn drives horizontal rod 102 to move upward. The upward movement of horizontal rod 102 drives transmission shaft 103 to move upward. The spiral groove on the surface of transmission shaft 103 slides upward inside guide block 106. Transmission shaft 103 rotates in the opposite direction due to the guiding action. The reverse rotation of transmission shaft 103 drives pusher plate 104 to rotate in the opposite direction. At the same time, as transmission shaft 103 moves upward, it drives pusher plate 104 and arc-shaped limiting strip 105 to move upward. As pusher plate 104 moves upward, it is subjected to the squeezing force of feed and rotates away from transmission shaft 103 to open. Pusher plate 104 gradually drives feed upward, preventing uneven mixing of feed at the bottom, preventing stratification, and reducing the mixing effect.
