Description

Technical Field

[0001] The present invention relates to the technical field of feed production, in particular to a batching scale for a feed processing production line. Background Art

[0002] Feed is a general term for food for all animals raised by humans. In a narrower sense, feed mainly refers to food for animals raised in agriculture or animal husbandry. Feed includes more than ten varieties of feed raw materials, such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, oil, meat and bone meal, grains, feed additives, etc. In order to ensure the yield of feed in production, the amount of each raw material needs to be precisely controlled. Therefore, batching scales are widely used in the feed industry. In order to meet the high-efficiency needs of modern animal husbandry production, feed batching scales have developed towards large-capacity and high-speed weighing, improving weighing speed and accuracy while reducing production costs.

[0003] The current feed processing and ingredient preparation process is generally as follows: during weighing, the feed raw materials are sent into the weighing cylinder through a screw conveyor or conveyor belt. At this time, the weighing sensor transmits the weight of the feed raw materials weighed in the weighing cylinder to the controller in real time. When the controller's set weight is reached, the controller controls the screw conveyor or conveyor belt to close and opens the weighing cylinder to discharge the weighed feed raw materials.

[0004] However, when the conveyor belt stops, the conveyed residual material continues to fall due to inertia, causing the residual material to freely fall from the discharge port to the bottom of the weighing cylinder to form an "air material column". This phenomenon causes the feed raw materials discharged from the discharge port to continue to fall into the weighing cylinder when the conveyor belt stops after the weight reaches the standard, resulting in inaccurate weight after weighing. In addition, during the weighing process, the fallen materials are in a state of stopping and accumulating. Due to the influence of oil or high humidity components, the accumulated materials are prone to adhesion and form lumps attached to the weighing position. This phenomenon not only leads to the accumulation of residual feed in the weighing cylinder, but also makes the weight of the feed finally entering the mixing process less than the expected value at the initial weighing, affecting the accuracy of the feed ratio and production efficiency. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem in the prior art that feed raw materials discharged after weighing continue to fall into a weighing cylinder, resulting in inaccurate weighing, and to propose a batching scale for a feed processing production line.

The outer walls of the rope winding columns bypass the bottom side outer walls of the two rope winding columns, and the outer walls of the rope winding columns bypass the top side outer wall of the extending end of the fixed rod. The pull ropes are made of elastic materials.

[0015] Furthermore, a second groove is formed in the upper inner wall of the through groove, and a shielding rod is in sliding connection with the inner wall of the second groove.

[0016] Furthermore, the material discharging and scraping component includes fixing plates.

The sliding groove II is in a horizontal inclined shape.

[0018] Compared with the prior art, the above solution has the following beneficial effects:

[0019] 1. When weighing the feed, through the cooperation of the weighing plate and the weighing sensor, when the feed falls on the weighing plate, the weighing plate can be lowered and cooperate with the weighing sensor for weight measurement. Then, through the cooperation of the fixed rod and the pulling rope, during the lowering process, the two closable intercepting plates can be synchronously driven to gradually rotate and merge, thereby gradually reducing the width of the material outlet, reducing the throughput per unit time. It can quickly carry out blanking and weighing at the initial stage to ensure the weighing efficiency, and can also reduce the feeding speed of the material when approaching the target weight, thereby reducing the overage error of the feed, which is beneficial to ensuring the weighing accuracy and weighing efficiency of the device.

[0020] 2. When weighing the feed, when the weighing is completed and the intercepting plate is closed, at this time, the weighing sensor can send a signal to control the driving motor to drive the weighing plate to flip, so as to discharge the weighed feed onto the discharge conveyor belt. At the same time, due to the reduction of the feed, the weighing plate can be driven to rise and reset by the weighing rod during the flipping process and reduce the contact with the inner wall of the weighing cylinder at the accumulation position, so that during the next weighing process, the lowering of the weighing plate can be used to scrape the inner wall of the weighing cylinder at the accumulation position remaining after the previous weighing, realizing targeted cleaning of the residue, preventing the residues of different formulas from mixing with each other, and ensuring the batching accuracy of the device.

[0021] 3. When weighing the feed, during the next weighing process, when the weighing plate is lowered, the top of the scraper can be downwardly extruded. Thus, with the cooperation of the scraper blade and the slider, the surface of the weighing plate where the material was accumulated during the previous weighing can be evenly scraped, which is beneficial to improving the accuracy after each feed weighing, beneficial to ensuring that the total amount of feed discharged each time conforms to the expected total amount, and further beneficial to ensuring the weighing accuracy of the device.

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0030] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "top surface", "bottom surface", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the indicated position or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not require or imply any actual relationship, order or relative importance between these entities or operations.

[0031] Example 1, refer to Figures 1-6 , a batching scale for a feed processing production line, including a weighing cylinder 1. An outlet conveyor belt 2 is installed at the bottom of the weighing cylinder 1, and an outlet port 3 is provided through the outer wall of one side of the weighing cylinder 1 corresponding to the outlet conveyor belt 2. An inlet conveyor belt 4 is installed corresponding to the weighing cylinder 1 on one side of the outlet conveyor belt 2;

[0032] Furthermore, a dynamic intercepting component 5 is arranged on the inner wall of the weighing cylinder 1. The dynamic intercepting component 5 includes a weighing plate 501, and the outer wall of the weighing plate 501 is in sliding fit with the inner wall of the weighing cylinder 1. A fixed rod 502 is fixedly connected to the inner wall of the weighing plate 501. Through grooves 9 are provided through the outer walls of both sides of the weighing cylinder 1 corresponding to the fixed rod 502, and both ends of the fixed rod 502 extend to the outside of the weighing cylinder 1 through the inner walls of the through grooves 9. The outer wall of the fixed rod 502 is in sliding fit with the inner wall of the through groove 9. A groove 503 is provided on the lower inner wall of the through groove 9, and an electric push rod 504 is fixedly installed on the lower inner wall of the groove 503. The top output end of the electric push rod 504 is fixedly installed with a weighing sensor 505, and a first spring 506 is fixedly connected to the upper weighing surface of the weighing sensor 505, and a weighing rod 507 is fixedly connected to the top of the first spring 506;

[0033] In the embodiment, when the device is in use, firstly, through the arrangement of the inlet conveyor belt 4, the feed can be conveyed and dropped from above the weighing cylinder 1 through the inlet conveyor belt 4, and when discharging materials subsequently, the weighed feed can be discharged through the outlet conveyor belt 2;

[0034] Next, during the weighing process, first, a first groove 503 is provided on the lower inner wall of the through groove 9, and an electric push rod 504 is fixedly installed on the lower inner wall of the first groove 503. The top output end of the electric push rod 504 is fixedly installed with a weighing sensor 505. A first spring 506 is fixedly connected to the upper weighing surface of the weighing sensor 505, and the top of the first spring 506 is fixedly connected to a weighing rod 507. Thus, under normal circumstances, the weighing plate 501 is located at the uppermost inner wall position of the through groove 9 driven by the first spring 506. When materials fall on the weighing plate 501, the weighing plate 501 can be lowered to squeeze the first spring 506, so that the first spring 506 can squeeze the weighing sensor 505 through elastic force to achieve weight measurement;

[0035] Next, intercepting plates 508 are symmetrically arranged on the inner wall of the weighing cylinder 1. A first rotating rod 509 is fixedly connected to the inner wall of the intercepting plate 508. The first rotating rod 509 is connected to a second rotating rod 510 through a transmission belt mechanism 512. The outer walls of the two ends of the second rotating rod 510 are rotatably connected to a fixed support plate 511. One side outer wall of the fixed support plate 511 is fixedly connected to one side outer wall of the weighing cylinder 1. Thus, the second rotating rod 510 can be supported by the fixed support plate 511;

[0036] Reset torsion springs 513 are symmetrically arranged on the outer wall of the second rotating rod 510. Spiral grooves 515 are symmetrically opened on the outer wall of the second rotating rod 510 corresponding to a group of sliding rods 514. The far ends of the two sliding rods 514 away from each other are in sliding fit with the inner wall of the spiral groove 515. The bottoms of the two sliding rods 514 are fixedly connected with a pulling rope 516. Winding columns 517 are symmetrically fixedly connected to the two side outer walls of the weighing cylinder 1 corresponding to the pulling rope 516. The outer wall of the winding column 517 bypasses the bottom side outer walls of the two winding columns 517, and the outer wall of the winding column 517 bypasses the top side outer wall of the extension end of the fixed rod 502. Thus, in the normal state, when the weighing plate 501 is at the uppermost inner wall position of the through groove 9, the pulling rope 516 will be squeezed by the fixed rod 502 at this time, so that the two sliding rods 514 are located at the farthest distance in the spiral groove 515 of the second rotating rod 510. At this time, the two intercepting plates 508 are in the maximum open state, and the reset torsion spring 513 is in the maximum stressed state;

[0037] Next, limiting grooves 8 are opened on the two side outer walls of the weighing cylinder 1 corresponding to the sliding rods 514. The close ends of the two sliding rods 514 are in sliding fit with the inner wall of the limiting groove 8, and the inner wall of the limiting groove 8 is T-shaped. Thus, the stability of the sliding rods 514 during the combined and separated movement is ensured;

[0038] When the weighing plate 501 descends for weighing, at this time the fixed rod 502 will gradually relax the extrusion of the pulling rope 516, so that the two sets of sliding rods 514 can be driven by the resilience of the reset torsion spring 513 to slide close to each other from the farthest distance in the spiral groove 515, causing the second rotating rod 510 to rotate. Furthermore, the first rotating rod 509 can be driven to rotate through the transmission belt mechanism 512, so that the two mergeable throttle plates 508 gradually rotate and merge, thereby gradually reducing the width of the feeding port and reducing the throughput per unit time. This can not only quickly carry out blanking and weighing at the initial stage to ensure the weighing efficiency, but also reduce the feeding speed of the material when approaching the target weight, thereby reducing the overage error of the feed and being beneficial to ensuring the weighing accuracy and weighing efficiency of the device;

[0039] Furthermore, when the weighing plate 501 is located in the through groove 9, it means that the weighing is completed, and at this time the two throttle plates 508 are merged and blocked with each other. Further, the descending distance of the weighing plate 501 is fixed, that is, it moves downward from the uppermost part of the through groove 9 to the lowermost part of the through groove 9. Regarding the adjustment of the weighing value, the position of the weighing sensor 505 can be adjusted by the telescopic movement of the electric push rod 504. When the weighing sensor 505 moves upward, the compression force of the first spring 506 becomes larger at this time, and the weighing range of the feed when the weighing plate 501 moves fixedly from the upper part to the lower part is a larger weight. Similarly, when the required feed weight is less, the weighing sensor 505 can be driven to move downward to reduce the compression force of the first spring 506, so that the weighing range of the feed when the weighing plate 501 moves fixedly from the upper part to the lower part is a smaller weight, thereby realizing the adjustment of the weighing range when the weighing plate �01 needs to move fixedly a certain distance, that is, when the weighing target is reached, the weighing sensor 505 can be triggered to transmit a signal;

[0040] Then, a second groove 518 is opened on the inner wall of the upper part of the through groove 9, and a shielding rod 519 is connected in a sliding fit with the inner wall of the second groove 518. Thus, under the action of gravity, the shielding rod 519 can block the gap between the upper part of the fixed rod 502 and the through groove 9 to prevent the material from leaking out.

[0041] Furthermore, discharge scraping components 6 are arranged on the outer walls on both sides of the weighing cylinder 1. The discharge scraping components 6 include fixing plates 601. The inner walls of the two fixing plates 601 are respectively rotatably connected to the outer walls of the two extending ends of the fixed rod 502. A driving motor 602 is fixedly installed on the outer wall on one side where the two fixing plates 601 are close to each other. One output end of the two driving motors 602 passes through the inside of the fixing plate 601 and is fixedly connected with a driving gear 603. Driven gears 604 are fixedly connected to the two extending ends of the fixed rod 502 corresponding to the driving gear 603, and the bottom side of the driven gear 604 is meshed and matched with the top side of the driving gear 603;

[0042] In an embodiment, when the weighing plate 501 is at the lowermost position of the through groove 9, that is, when the weighing is completed, the weighing sensor 505 transmits a signal to control the driving motor 602. Through the two extending ends of the fixed rod 502, a driven gear 604 is fixedly connected to the corresponding driving gear 603, and the bottom side of the driven gear 604 is meshed and matched with the top side of the driving gear 603. Thus, the driving motor 602 can drive the weighing plate 501 to flip 180 degrees, so as to discharge the weighed feed onto the discharge conveyor belt 2;

[0043] Then, on the outer walls of the two approaching sides of the two fixing plates 601, connecting plates 605 are symmetrically and fixedly connected. On the outer walls of both sides of the weighing cylinder 1, first chutes 10 are provided corresponding to the connecting plates 605. The inner walls of the two groups of connecting plates 605 are in close contact and slidably connected to the inner walls of the first chutes 10, thus ensuring the stability of the driving motor 602 during lifting and moving;

[0044] At this time, due to the reduction of the feed, during the flipping process of the weighing plate 501, the weighing plate 501 can be driven to rise by the resilience of the first spring 506, so that the weighing plate 501 can reduce contact with the inner wall of the weighing cylinder 1 at the stacking position during flipping and resetting. In the next weighing process, the weighing plate 501 can be lowered to scrape the inner wall of the weighing cylinder 1 at the stacking position where the residue remained after the previous weighing, so as to achieve targeted removal of the residue and prevent the residues of different formulas from mixing with each other;

[0045] Next, to avoid the situation that the two shut-off plates 508 are separated and leak materials due to the extrusion of the pull rope 516 during the flipping and rising process of the weighing plate 501, through grooves 521 are symmetrically provided at the bottom of the auxiliary block 520, and a second spring 522 is fixedly connected to the inner wall of the groove 521. The bottom of the second spring 522 is fixedly connected with a clamping block 523, and the outer wall of the clamping block 523 is in close contact and slidable with the inner wall of the groove 521. The opposite side walls of the two clamping blocks 523 on the same side are arranged in a long inclined plane shape, and the adjacent side walls of the two clamping blocks 523 on the same side are arranged in a short inclined plane shape. Thus, under normal circumstances, when the shut-off plates 508 are flipped and combined, the two sliding rods 514 will squeeze the long inclined plane position of the clamping block 523, and the clamping block 523 can be pressed into the groove 521 with only a small force;

[0046] When the weighing plate 501 is flipped and rising, at this time, the two combined sliding rods 514 will be separated synchronously. Thus, the separation difficulty can be increased through the short inclined plane positions of the two clamping blocks 523 and the elastic extension performance of the pull rope 516 itself, achieving the delayed separation effect of the shut-off plates 508 and avoiding the premature separation and opening of the two shut-off plates 508 before the weighing plate 501 rises and resets.

[0047] Further, a redundant cleaning component 7 is provided on the inner wall of the weighing cylinder 1. The redundant cleaning component 7 includes a scraping plate 701, and the outer wall of the scraping plate 701 is in sliding fit with the inner wall of the weighing cylinder 1. Sliders 702 are fixedly connected to the outer walls on both sides of the scraping plate 701. Second chutes 11 are provided on the inner walls on both sides of the weighing cylinder 1 corresponding to the sliders 702, and the outer walls of the sliders 702 are in sliding fit with the inner walls of the second chutes 11. A scraping knife 703 is fixedly connected to the top of the side of the scraping plate 701 facing the discharge port 3 corresponding to the weighing plate 501. A tension spring 704 is fixedly connected to the outer walls of the two sliders 702 away from the discharge port 3, and the other end of the tension spring 704 is fixedly connected to the inner wall of the second chute 11;

[0048] In the embodiment, when the weighing plate 501 descends for weighing at a certain time, at this time, sliders 702 are fixedly connected to the outer walls on both sides of the scraping plate 701. Second chutes 11 are provided on the inner walls on both sides of the weighing cylinder 1 corresponding to the sliders 702, and the outer walls of the sliders 702 are in sliding fit with the inner walls of the second chutes 11. A scraping knife 703 is fixedly connected to the top of the side of the scraping plate 701 facing the discharge port 3 corresponding to the weighing plate 501. The second chutes 11 are in a horizontal inclined shape, so that when the bottom of the weighing plate 501 comes into contact with and presses against the top of the scraping plate 701, the surface of the weighing plate 501 where materials were piled up last time can be evenly scraped, which is beneficial to improving the accuracy after each weighing of the feed and ensuring that the total amount of feed discharged each time conforms to the expected total amount;

[0049] Then, a tension spring 704 is fixedly connected to the outer walls of the two sliders 702 away from the discharge port 3, and the other end of the tension spring 704 is fixedly connected to the inner wall of the second chute 11. Thus, after the weighing plate 501 is flipped and reset, the scraping plate 701 can be driven to move and reset by the tension spring 704.

[0050] The working principle of the present invention: During the weighing process, the weighing plate 501 is located at the uppermost inner wall position of the through groove 9 driven by the first spring 506. When materials fall on the weighing plate 501, the weighing plate 501 can be lowered and the first spring 506 can be compressed, so that the first spring 506 can compress the weighing sensor 505 through elastic force to achieve weight measurement;

[0051] Next, when the weighing plate 501 descends for weighing, at this time, the fixed rod 502 will gradually release the extrusion of the pulling rope 516, so that the resilience of the reset torsion spring 513 can drive the two groups of sliding rods 514 to slide closer to each other from the farthest distance in the spiral groove 515, causing the second rotating rod 510 to rotate. Furthermore, it can drive the first rotating rod 509 to rotate through the transmission belt mechanism 512, making the two combinable throttle plates 508 gradually rotate and combine, thereby gradually narrowing the width of the feeding port and reducing the throughput per unit time. This can not only quickly conduct blanking and weighing at the initial stage to ensure the weighing efficiency, but also reduce the feeding speed of the material when approaching the target weight, thus reducing the overage error of the feed;

[0052] Next, when the weighing plate 501 is at the lowest position of the through groove 9, that is, when the weighing is completed, at this time, the weighing sensor 505 transmits a signal to drive the weighing plate 501 to flip 180 degrees through the driving motor 602, realizing the discharge of the weighed feed onto the discharge conveyor belt 2. At this time, due to the reduction of the feed, when the weighing plate 501 flips, it can be driven to rise by the resilience of the first spring 506, so that the weighing plate 501 can reduce contact with the inner wall of the weighing cylinder 1 at the accumulation position during the flip reset. In the next weighing process, the weighing plate 501 can be used to scrape the inner wall of the accumulation position of the weighing cylinder 1 where the residue remained after the previous weighing, realizing targeted removal of the residue and preventing the residues of different formulas from mixing with each other;

[0053] Next, when the weighing plate 501 rises during the flip, at this time, the two combined sliding rods 514 will separate synchronously. Thus, the separation difficulty can be increased through the short inclined plane positions of the two clamping blocks 523 and the elastic extension performance of the pulling rope 516 itself, realizing the delayed separation effect of the throttle plate 508 and preventing the two throttle plates 508 from separating and opening in advance before the weighing plate 501 rises and resets;

[0054] Next, during a certain weighing process when the weighing plate 501 descends, when the bottom of the weighing plate 501 contacts and squeezes the top of the scraper 701, it can evenly scrape the side of the weighing plate 501 where the material was accumulated last time, which is beneficial to improving the accuracy after each feed weighing and ensuring that the total amount of feed discharged each time conforms to the expected total amount.

[0055] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention should be determined by the scope defined by the claims.
