Description

Technical Field

[0001] This utility model relates to the field of seed packaging equipment technology, and specifically discloses a quantitative seed packaging device. Background Technology

[0002] Seeds are organs unique to seed plants, and their main function is reproduction. The shape, size, color, and surface texture of seeds vary depending on the plant species. In the process of modern seed production, quantitative packaging devices are usually used to package seeds to facilitate seed storage, transportation, and use.

[0003] Chinese patent CN222347356U discloses a seed quantitative packaging machine, including a feeding device for supporting quantitative packaging and quantitative feeding. The feeding device is equipped with a storage device for storing seeds, and a feeding device installed below the storage device for alternating feeding after quantitative feeding and three-way discharge. The feeding device includes a transfer tray with six quantitative bins evenly distributed on it. A truncated cone is installed at the center of the transfer tray, and six push rods are evenly distributed around the circumference of the truncated cone. The seed quantitative packaging machine of this utility model achieves simultaneous feeding and filling from multiple openings by setting up a three-outlet feeding system after quantitative feeding, thus improving the packaging speed. The alternating quantitative feeding system synchronizes feeding and dispensing, further increasing the packaging speed. The rotating pusher assists in seed feeding and prevents material accumulation at the inlet. However, the above-mentioned packaging machine can only limit the volume of seeds placed in the same quantitative bin during use and lacks a weighing function, making it unsuitable for packaging different weights of the same type of seed. Furthermore, the machine lacks a bag-supporting and limiting structure, which can easily cause bags placed on the packaging table to tip over and fall, affecting the efficiency of seed packaging. Therefore, to solve the above problems, this utility model proposes a quantitative seed packaging device. Utility Model Content

[0004] The present invention aims to provide a quantitative seed packaging device that can weigh seeds of different weights to meet the packaging needs of seeds of different specifications, improve the practicality of the packaging device, and has a bag supporting mechanism to prevent the packaging bag from tipping over and falling off the shelf during the seed filling process, thus ensuring the efficiency of quantitative seed packaging.

[0005] This utility model is achieved through the following technical solution:

[0006] A quantitative seed packaging device includes a storage mechanism, a quantitative weighing mechanism below the storage mechanism, and a bag-supporting mechanism below the quantitative weighing mechanism. The storage mechanism includes a storage bin, with four first discharge pipes arranged in a circumferential array connected below the storage bin. A stirring rod is installed inside the storage bin. The quantitative weighing mechanism includes a second support, with four distributing bins arranged in a circumferential array at the upper end of the second support. Second discharge pipes are connected below the distributing bins. The bag-supporting mechanism includes a bearing plate, with a support plate above the bearing plate. A second motor is connected to the lower center of the support plate. Four placement plates arranged in a circumferential array are connected above the support plate. A first mounting plate is installed above the placement plates. A second mounting plate is installed on one side of the first mounting plate. Multiple electrically controlled suction cups are installed on the sides of the first and second mounting plates that are close to each other. A packaging bag is installed on the side of the electrically controlled suction cups away from the mounting plates.

[0007] As a further feature of the above scheme, the upper end of the storage silo is connected to a top plate, the upper end of the stirring rod passes through the middle of the top plate and is rotatably connected to the top plate, the upper end of the stirring rod is connected to a first motor, which can provide power for the rotation of the stirring rod, the outer side of the first motor is connected to the top plate through a first base, which can provide support for the first motor and facilitate the installation and maintenance of the first motor, and a feed pipe is provided on one side above the top plate to facilitate the injection of seeds into the silo, the outer side of the storage silo is connected to a first bracket, the lower end of the first bracket is connected to the upper end of a second bracket, which can provide support for the storage silo.

[0008] As a further configuration of the above scheme, the four first discharge pipes correspond to the positions of the four distribution bins, which facilitates independent discharge of materials by the four first discharge pipes. Weighing sensors are connected to both sides of each distribution bin to facilitate weighing the weight of the distribution bin and the seeds inside. The lower ends of the weighing sensors are connected to the second bracket to facilitate the installation and maintenance of the weighing sensors. The lower end of the second bracket is connected to the support plate to facilitate the installation and maintenance of the second bracket and its connecting components. A first solenoid valve and a second solenoid valve are respectively connected to one end of the first discharge pipe and the second discharge pipe to facilitate the control of the discharge of materials by the first discharge pipe and the second discharge pipe.

[0009] As a further feature of the above solution, an annular groove is provided above the support plate, and multiple limiting rods arranged in a circular array are connected below the support plate. The limiting rods are slidably connected to the annular groove, which can limit the rotation direction of the support plate and reduce the downward pressure applied by the second motor of the support plate. The outer side of the second motor is connected to the support plate through a second base, which facilitates the installation and maintenance of the second motor.

[0010] As a further feature of the above solution, a first guide rod and a first telescopic rod are respectively connected to both ends of one side of the first mounting plate, and a second guide rod and a second telescopic rod are respectively connected to both ends of the second mounting plate near the first telescopic rod. The first guide rod and the second guide rod pass through the interior of the second mounting plate and the first mounting plate respectively and are slidably connected to the second mounting plate, which can limit the position of the first mounting plate and the second mounting plate and the connected electric suction cup. A third bracket is connected to the outer side of both the first telescopic rod and the second telescopic rod.

[0011] As a further feature of the above solution, a controller is provided on one side of the bag-supporting mechanism to facilitate the control of the operation of relevant components in the device.

[0012] In this invention, the projections of the four first discharge pipes, the distribution bins, and the storage plate on the support plate overlap each other in the vertical direction. The second motor in this invention is a servo motor.

[0013] The present invention has the following beneficial effects during use:

[0014] The combination of the first motor and the stirring rod in the storage mechanism can disperse the seeds in the storage bin, preventing the seeds from clogging the four first discharge pipes and ensuring the discharge effect of the first discharge pipes. The use of the dispensing bin and weighing sensor in the quantitative weighing mechanism can quantitatively weigh the seeds discharged from the first discharge pipe, making it convenient for users to accurately grasp the weight of the seeds packaged in the packaging bag.

[0015] The design of the arc groove and limiting rod in the bag-supporting mechanism can restrict the rotation direction of the support plate and the components above it, while providing support for the support plate and the components above it, reducing the downward pressure exerted by the support plate and the components above it on the second motor, and extending the service life of the second motor.

[0016] The combination of the electrically controlled suction cup, the first mounting plate, the second mounting plate, the first telescopic rod, the second telescopic rod, the first guide rod, and the second guide rod allows for adjustment of the distance between the first and second mounting plates by extending and retracting the first and second telescopic rods. This, in turn, adjusts the distance between the electrically controlled suction cups connected to the first and second mounting plates, enabling the electrically controlled suction cups to adhere to both sides of the packaging bag, opening it up and restricting its position to prevent it from tipping over and falling off the shelf.

[0030] An embodiment discloses a quantitative seed packaging device, including a storage mechanism 1, a quantitative weighing mechanism 2 disposed below the storage mechanism 1, and a bag-supporting mechanism 3 disposed below the quantitative weighing mechanism 2. The storage mechanism 1 includes a storage bin 11, and four first discharge pipes 13 arranged in a circumferential array are connected to the lower part of the storage bin 11. A stirring rod 15 is disposed inside the storage bin 11. The quantitative weighing mechanism 2 includes a second support 21, and four distributing bins 22 arranged in a circumferential array are disposed at the upper end of the second support 21. A second distributing bin 22 is connected to the lower part of the distributing bin 22. The discharge pipe 24 and the bag support mechanism 3 include a bearing plate 31, a support plate 32 above the bearing plate 31, a second motor 33 connected to the lower center of the support plate 32, four placement plates 34 arranged in a circular array above the support plate 32, a first mounting plate 35 above the placement plate 34, a second mounting plate 36 on one side of the first mounting plate 35, and multiple electrically controlled suction cups 37 installed on the side of the first mounting plate 35 and the second mounting plate 36 that are close to each other. A packaging bag 4 is placed on the side of the electrically controlled suction cup 37 that is away from the mounting plate.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, the upper end of the storage silo 11 is connected to a top plate 12. The upper end of the stirring rod 15 passes through the middle of the top plate 12 and is rotatably connected to the top plate 12. The upper end of the stirring rod 15 is connected to a first motor 16, which can provide power for the rotation of the stirring rod 15. The outer side of the first motor 16 is connected to the top plate 12 through a first base 161, which can provide support for the first motor 16 and facilitate the installation and maintenance of the first motor 16. A feed pipe 121 is provided on one side above the top plate 12 to facilitate the injection of seeds into the silo. The outer side of the storage silo 11 is connected to a first bracket 17. The lower end of the first bracket 17 is connected to the upper end of the second bracket 21, which can provide support for the storage silo 11.

[0032] like Figure 1 and Figure 4 As shown, the four first discharge pipes 13 correspond to the positions of the four distribution bins 22, facilitating independent discharge of materials by the four first discharge pipes 13. Weighing sensors 23 are connected to both sides of each distribution bin 22, facilitating the weighing of the distribution bin 22 and the seeds inside. The lower ends of the weighing sensors 23 are connected to the second bracket 21, facilitating the installation and maintenance of the weighing sensors 23. The lower end of the second bracket 21 is connected to the support plate 31, facilitating the installation and maintenance of the second bracket 21 and its connecting components. One end of each of the first discharge pipe 13 and the second discharge pipe 24 is connected to a first solenoid valve 14 and a second solenoid valve 25, respectively, facilitating the control of the discharge of materials by the first discharge pipe 13 and the second discharge pipe 24.

[0033] like Figure 5 and Figure 6 As shown, an annular groove 311 is provided above the support plate 31, and multiple limiting rods 321 arranged in a circular array are connected below the support plate 32. The limiting rods 321 are slidably connected to the annular groove 311, which can limit the rotation direction of the support plate 32 and reduce the downward pressure applied by the second motor 33 of the support plate 32. The outer side of the second motor 33 is connected to the support plate 31 through the second base 331, which facilitates the installation and maintenance of the second motor 33.

[0034] like Figure 1 , Figure 7 , Figure 8 and Figure 9 As shown, a first guide rod 351 and a first telescopic rod 352 are respectively connected to both ends of one side of the first mounting plate 35. A second guide rod 361 and a second telescopic rod 362 are respectively connected to both ends of the second mounting plate 36 near the first telescopic rod 352. The first guide rod 351 and the second guide rod 361 pass through the interior of the second mounting plate 36 and the first mounting plate 35, and are slidably connected to the second mounting plate 36, which can limit the position of the first mounting plate 35, the second mounting plate 36, and the connected electric suction cup 37. A third bracket 38 is connected to the outer side of the first telescopic rod 352 and the second telescopic rod 362. The lower end of the third bracket 38 is connected to the shelf 34, which can provide stable support for the first telescopic rod 352, the second telescopic rod 362, and other components, facilitating the installation and maintenance of the above components.

[0035] like Figure 1 As shown, a controller 5 is provided on one side of the bag-supporting mechanism 3 to facilitate the control of the operation of related components in the device.

[0036] The quantitative seed packaging device disclosed in this embodiment injects sufficient seeds into the storage bin 11 through the feed pipe 121 before use. The controller 5 starts the first motor 16, which drives the stirring rod 15 to rotate. The weight of the quantitative seeds is set on the controller 5. The weight of the unseeded dispensing bin 22, the second discharge pipe 24, and the second electrically controlled valve are measured using the weighing sensor 23, and the seeds are tare. At this time, the measurement value of the weighing sensor 23 displayed on the controller 5 is zero. The target weighing value is set on the controller 5. The controller 5 simultaneously starts the four first solenoid valves 14, which inject sufficient seeds into the four dispensing bins 22 through the four first discharge pipes 13 respectively. When the values ​​transmitted back to the controller 5 by the four sets of weighing sensors 23 reach the preset value, the four first solenoid valves 14 immediately close. A packaging bag 4 is picked up and placed between the vacuum suction cups on the side of the first mounting plate 35 and the second mounting plate 36 on a shelf 34. The controller 5 simultaneously controls the first telescopic rod 352 and the second telescopic rod 352. As rod 362 retracts, the vacuum suction cups on both sides open. When the vacuum suction cups on both sides contact the sides of the packaging bag 4, they adsorb the packaging bag 4. Simultaneously, the first telescopic rod 352 and the second telescopic rod 362 extend, causing the vacuum suction cups on both sides to move in opposite directions, thus opening the packaging bag 4. The first telescopic rod 352 and the second telescopic rod 362 then close. During the extension and retraction of the first telescopic rod 352 and the second telescopic rod 362, the first guide rod 351 and the second guide rod 361 respectively approach the second mounting plate 36. One end of rod 352 and the end of first mounting plate 35 near the second telescopic rod 362 slide. After the bag is supported, the second solenoid valve 25 opens, and the seeds in the dispensing bin 22 are discharged into the packaging bag 4 through the discharge pipe. When the data transmitted back to the controller 5 by the weighing sensor 23 returns to zero, the second solenoid valve 25 is closed, the electric suction cup 37 is closed, the fixing of the packaging bag 4 is released, and the packaging bag 4 containing the seeds is removed from the placement plate 34. The above-mentioned filling, bag supporting and discharging operations are repeated to continue the quantitative packaging operation of seeds.

[0037] The above operations can be programmed into the terminal device as follows: retracting the first telescopic rod 352 and the second telescopic rod 362, opening the vacuum suction cup, extending the first telescopic rod 352 and the second telescopic rod 362, closing the first telescopic rod 352 and the second telescopic rod 362, opening the first solenoid valve 14, and activating the weighing sensor 23. When the value set by the weighing sensor 23 is reached, the first solenoid valve 14 closes, the second solenoid valve 25 opens, and when the value of the weighing sensor 23 returns to zero, the second solenoid valve 25 closes, and the vacuum suction cup closes. This sequence of operations is then transmitted to the controller 5. When performing quantitative seed packaging, users only need to select the corresponding process on the controller 5 to achieve linkage between the components. Users do not need to control each component individually, thus improving the automation level of the device and the efficiency of quantitative seed packaging.

[0038] In practical use, when the amount of seeds to be packaged is small, it can be used in conjunction with the second motor 33. One worker holds the bag up on a shelf 34 using components such as the first mounting plate 35, the second mounting plate 36, and the electrically controlled suction cup 37. The second motor 33 starts and drives the support plate 32 and the shelf 34 to rotate, thereby rotating the held packaging bag 4. The held packaging bag 4 is rotated to the bottom of another distribution bin 22 to receive the seeds discharged from the other distribution bin 22. The electrically controlled suction cup 37 is then turned off, and another worker removes the packaging bag 4 containing the seeds. During the intermittent starting and stopping of the second motor 33, one person is always responsible for placing the packaging bag 4 on the empty shelf 34, and the other person is responsible for removing the packaging bag 4 containing the seeds.

[0039] The packaging bag 4, controller 5, storage bin 11, feed pipe 121, first discharge pipe 13, first solenoid valve 14, stirring rod 15, first motor 16, first support 17, distributing bin 22, weighing sensor 23, second discharge pipe 24, second solenoid valve 25, bearing plate 31, second motor 33, placement plate 34, first guide rod 351, first telescopic rod 352, second mounting plate 36, second guide rod 361, second telescopic rod 362, and electrically controlled suction cup 37 in the quantitative seed packaging device disclosed in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
