Description
Technical Field
[0001] This utility model relates to the field of crop seed packaging technology, specifically a quantitative device for crop seed packaging. Background Technology
[0002] In the crop seed packaging industry, accurate quantitative packaging is crucial. Traditional crop seed packaging methods face numerous challenges in the quantitative stage, resulting in high packaging costs. Early on, some packaging companies used manual quantitative methods for crop seed packaging. However, manual operation is not only extremely inefficient but also makes it difficult to ensure the precise consistency of the weight or quantity of each package of seeds. To achieve a certain level of packaging accuracy, a large amount of manual labor is required for repeated verification and adjustments, which significantly increases labor costs. At the same time, manual operation is susceptible to human factors such as fatigue and negligence, further affecting packaging quality, leading to increased defect rates, material waste, and indirectly increasing production costs.
[0003] With technological advancements, some enterprises have begun to introduce simple mechanical equipment for quantitative seed packaging. However, these devices are often complex in structure, involving numerous components and intricate control systems. On the one hand, the procurement cost of this equipment is extremely high, representing a significant expense for many small and medium-sized seed production enterprises; on the other hand, the complex structure increases the difficulty of maintenance, requiring regular upkeep and repairs by professional technicians. This not only increases maintenance costs but also, if the equipment malfunctions, the lengthy repair time can severely impact production progress, resulting in additional economic losses. Therefore, this utility model provides a quantitative packaging device for crop seeds. Utility Model Content

[0007] The drive unit is located at one end of the frame and is used to drive the transmission roller to rotate;
[0008] The transmission unit is located on one side of the upper part of the frame and is used to transmit the driving force of the drive unit to the metering unit.

[0014] Beneficial effects
[0015] This invention provides a quantitative device for packaging crop seeds. Compared with the prior art, it has the following advantages:
[0016] 1. This quantitative device for packaging crop seeds uses an arc-shaped opening on a baffle plate in conjunction with a feeding hopper and a guide pipe. As the baffle plate rotates, the arc-shaped opening opens the feeding channel to allow seeds to fall when it reaches a specific position, and stops falling when it leaves that position. This cycle can precisely control the number of crop seeds falling into the guide pipe each time, thereby ensuring accurate seed quantity in packaging, effectively avoiding excessive or insufficient seed packaging, and improving packaging quality and product consistency.
[0017] 2. This quantitative packaging device for crop seeds uses a grooved wheel mechanism to achieve intermittent rotation of the transmission roller, driving the conveyor belt to move intermittently. At the same time, it uses connecting rods, transmission belt groups, and bevel gear transmission to transmit the power of the motor to the quantitative unit. The overall structure is simple, and the various transmission components work together in a reasonable manner. This not only reduces the complexity of the control system and lowers the equipment cost, but also ensures that this mature mechanical transmission method has high reliability and high transmission efficiency, and can stably and continuously complete the quantitative packaging of crop seeds, thereby improving production efficiency.

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-4 This utility model provides a technical solution: a quantitative device for packaging crop seeds, specifically including the following embodiments:
[0025] Example 1: A quantitative device for packaging crop seeds includes a frame 1. Two sets of transmission rollers 3 are rotatably mounted on the upper inner wall of the frame 1. A conveyor belt 4 is provided on the transmission rollers 3. A quantitative feeding assembly 2 is provided on the upper part of the frame 1. The quantitative feeding assembly 2 includes: a quantitative unit 21, which is located on one side of the upper part of the frame 1 and includes a mounting frame 211 fixed to one side of the upper part of the frame 1. A transmission box 212, a feed hopper 215, and a guide pipe 216 are fixed on one side of the mounting frame 211. A rotating shaft 213 is rotatably mounted on the upper end of the transmission box 212. A baffle plate 214 is fixed at the top of the rotating shaft 213. The baffle plate 214 has an arc-shaped opening, and the rotation diameter of the arc-shaped opening is related to the feed hopper 215 and the guide pipe 216. The tube 216 is on the same vertical line; the drive unit 22 is set at one end of the frame 1 and is used to drive the transmission roller 3 to rotate; the transmission unit 23 is set on one side of the upper part of the frame 1 and is used to transmit the driving force of the drive unit 22 to the quantitative unit 21; when the arc-shaped opening on the baffle plate 214 rotates to be on the same vertical line as the feed hopper 215 and the guide tube 216, the crop seeds in the feed hopper 215 fall into the guide tube 216 through the arc-shaped opening and finally enter the packaging box being transported below, realizing quantitative feeding; as the baffle plate 214 continues to rotate, the arc-shaped opening leaves the vertical line, the channel between the feed hopper 215 and the guide tube 216 is blocked, and feeding stops.
[0026] Example 2: The main difference between this example and the first technical solution is that: a quantitative device for packaging crop seeds, the drive unit 22 includes a motor 221 fixedly installed at the front end of the frame 1, and an active dial 223 and a cylindrical pin 222 are welded to the output shaft at the end of the motor 221. A grooved wheel 224 is connected to the transmission roller 3. The grooved wheel 224, the active dial 223 and the cylindrical pin 222 cooperate with each other to form a grooved wheel mechanism, thereby driving the transmission roller 3 on the grooved wheel 224 to rotate intermittently. The transmission unit 23 includes a connecting rod 231 fixed to the output shaft of the motor 221, and the connecting rod 231 is connected to the transmission unit 23. A transmission belt assembly 232 is installed at the end of the rod 231. The transmission belt assembly 232 consists of two sets of transmission pulleys and a transmission belt. It drives the two sets of transmission pulleys to rotate synchronously through transmission. One set of transmission pulleys is fixed to the connecting rod 231, while the other set of transmission pulleys is rotatably connected to the outer wall of the frame 1 through a shaft. A first bevel gear 233 is also connected to the shaft. A second bevel gear 234 that meshes with the first bevel gear 233 is fixed at the lower end of the rotating shaft 213. Both the first bevel gear 233 and the second bevel gear 234 are located inside the transmission box 212. The output shaft at the end of the motor 221 rotates, driving the welded... The active dial 223 and the cylindrical pin 222 rotate together. The active dial 223 and the cylindrical pin 222 cooperate with the grooved wheel 224 connected to the transmission roller 3 to form a grooved wheel mechanism. As the active dial 223 rotates, the cylindrical pin 222 enters the groove of the grooved wheel 224, driving the grooved wheel 224 to rotate, which in turn causes the transmission roller 3 on the grooved wheel 224 to rotate synchronously. When the cylindrical pin 222 leaves the groove of the grooved wheel 224, the grooved wheel 224 stops rotating, realizing the intermittent rotation of the transmission roller 3, thereby driving the transmission belt 4 to move intermittently; when the output shaft of the motor 221 rotates, the connecting rod fixed on it... As 231 rotates, the transmission belt assembly 232 installed at the end of the connecting rod 231 begins to work. The transmission belt assembly 232 consists of two sets of transmission wheels and a transmission belt. Through transmission, it drives the two sets of transmission wheels to rotate synchronously. One set of transmission wheels is fixed to the connecting rod 231 and rotates with the connecting rod 231. The other set of transmission wheels is rotatably connected to the outer wall of the frame 1 through a shaft. The first bevel gear 233 connected to its shaft also rotates. When the first bevel gear 233 rotates, the second bevel gear 234, which meshes with it and is fixed at the lower end of the rotating shaft 213, begins to rotate, thereby driving the rotating shaft 213 to rotate.
[0027] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0028] During operation, the motor 221, fixedly mounted at the front end of the frame 1, is first turned on. The output shaft of the motor 221 rotates, driving the active dial 223 and cylindrical pin 222 welded to it to rotate together. The active dial 223 and cylindrical pin 222 cooperate with the grooved wheel 224 connected to the transmission roller 3 to form a grooved wheel mechanism. As the active dial 223 rotates, the cylindrical pin 222 enters the groove of the grooved wheel 224, driving the grooved wheel 224 to rotate, thereby causing the transmission roller 3 on the grooved wheel 224 to rotate synchronously. When the cylindrical pin 222 leaves the groove of the grooved wheel 224, the grooved wheel 224 stops rotating, realizing the intermittent rotation of the transmission roller 3, thereby driving the transmission belt 4 to move intermittently. When the output shaft of the motor 221 rotates, the connecting rod 231 fixed to it rotates accordingly, and the transmission belt assembly 232 mounted at the end of the connecting rod 231 starts to work. The transmission belt assembly 232 consists of two sets of transmission wheels and one set of transmission belts. Through transmission, it drives the two sets of transmission wheels to rotate synchronously. One set of transmission wheels and the transmission belt assembly 232 consists of two sets of transmission wheels and one set of transmission belts. The connecting rod 231 is fixed and rotates with the rotation of the connecting rod 231. Another set of transmission wheels is rotatably connected to the outer wall of the frame 1 through a shaft. The first bevel gear 233 connected to the shaft also rotates. When the first bevel gear 233 rotates, the second bevel gear 234, which meshes with it and is fixed at the lower end of the rotating shaft 213, begins to rotate, thereby driving the rotating shaft 213 to rotate. The baffle plate 214 located at the top of the rotating shaft 213 also rotates. When the arc-shaped opening on the baffle plate 214 rotates to meet the feed hopper... When 215 and the guide pipe 216 are on the same vertical line, the crop seeds in the feed hopper 215 fall into the guide pipe 216 through the arc-shaped opening and finally enter the packaging box being transported below, realizing quantitative feeding; as the baffle plate 214 continues to rotate, the arc-shaped opening leaves the vertical line, the channel between the feed hopper 215 and the guide pipe 216 is blocked, and feeding stops; this cycle is repeated to realize the quantitative delivery of crop seeds to the conveyor belt 4, completing the quantitative work for packaging.
