Abstract
Description
Technical Field
[0001] This utility model relates to the field of rice printing and seeding machine technology, specifically a rice printing and seeding machine that can quickly determine the position of the seedling tray. Background Technology
[0002] The rice printing planter uses precise positioning, mechanical adsorption, or adhesive fixation to "print" rice seeds onto a carrier (such as biodegradable paper film, seedling tray, or field soil) at a preset density and spacing. The seed spacing is fixed, the seedlings are not crowded, the root system is fully developed, the stems are thick, the number of leaves is large, and the tillering ability is strong.
[0003] The existing Chinese utility model patent with publication number CN212975688U discloses an automatic printing and seeding machine, including a frame and a conveying assembly for conveying a roll of paper; a dispensing mechanism for diverting glue and dispensing the diverted glue onto the roll of paper; a reciprocating motion mechanism for driving the dispensing mechanism to perform reciprocating dispensing operations; and a control mechanism for controlling the speed of the reciprocating dispensing operation of the dispensing mechanism to match the running speed of the conveying assembly. This utility model uses a servo drive to enable the dispensing mechanism to complete high-speed reciprocating motion, and the control assembly performs high-precision control operations, resulting in high dispensing accuracy and good consistency. It effectively solves the problems of high dispensing speed, strong dispensing consistency, and stable material supply in agricultural printing and seeding operations, effectively improving the smoothness of the production process, increasing production efficiency, and improving the current production situation.
[0004] The aforementioned automatic printing and seeding machine applies colloid evenly to the surface of seed paper via a dispensing mechanism. After sowing, manual cutting of the seed paper with seeds on it according to the size of the seed tray is required, which is very inconvenient. Furthermore, existing printing and seeding machines generally use vibration to distribute the seeds evenly on the surface of the seed paper. Because the seeds are distributed on the upper surface of the seed paper, a large number of seeds will remain on the top of the seed paper, which may cause the seed paper to break under the weight of the seeds. In addition, the seeds will move with the seed paper and scatter, which is very inconvenient to collect afterward. Utility Model Content
[0005] To address the shortcomings of existing technologies, this invention provides a rice printing and seeding machine that can quickly determine the position of the seedling tray, solving the problems of seed retention and the inability to cut the seed-adhesive paper according to the size of the seedling tray.
[0006] To achieve the above objectives, this utility model provides the following technical solution: A rice printing and seeding machine capable of quickly determining the position of the seedling tray includes a support frame, a limit roller movably mounted at the rear end of the support frame, and a printing mechanism disposed above the support frame.
[0007] The limiting assembly includes a support plate fixedly installed above a support frame, a limiting frame fixedly installed above the support plate, an adjusting cylinder fixedly installed below the limiting frame, a movable block fixedly installed at the bottom end of the adjusting cylinder, and a guide roller movably installed on one side of the support plate and the movable block.
[0008] A conveying assembly, positioned above the support frame, is used to convey seeds;
[0009] The dispensing assembly is located above the support frame to dispense adhesive onto the seed paper.
[0010] A cutting component, located above the support frame, is used to cut the seed paper.
[0011] Preferably, the conveying assembly includes a receiving hopper fixedly installed on one side of the support plate, a conveying pipe fixedly installed at the bottom center of the receiving hopper, and a grain suction machine fixedly installed at the top of the conveying pipe.
[0012] Preferably, a material feeding pipe is fixedly installed below the grain suction machine, and the conveying assembly also includes a movable plate movably installed between the support plates. Support springs are inserted at the four corners of the movable plate, and a vibration motor is fixedly installed at the bottom of the movable plate.
[0013] Preferably, the dispensing assembly includes a support roller movably mounted on one side of the support plate, a dispensing roller movably mounted above the support roller, a gear movably mounted on the top of the support plate, a stepper motor on one side of the support plate, a glue delivery tube fitted into one side of the support plate, and a partition plate provided below the dispensing roller.

[0016] Beneficial effects
[0017] This invention provides a rice printing and seeding machine that can quickly determine the position of the seedling tray. Compared with the prior art, it has the following advantages:
[0018] (1) The rice printing and seeding machine that can quickly determine the position of the seedling tray has a movable plate. The movable plate is installed at an angle between the support plates, and the top surface points to the feeding pipe. Driven by the vibration motor, the movable plate will vibrate and apply an upward force to the seeds on the seed paper so that the seeds are evenly distributed on the surface of the seed paper. The seeds that are not stuck by the glue will be discharged into the receiving hopper at the bottom of the movable plate with the vibration, so that the excess seeds on the seed paper can be collected by the receiving hopper. The movable plate can also support the seed paper to prevent the seed paper from breaking under the weight of the seeds.
[0019] (2) This rice printing and seeding machine that can quickly determine the position of the seedling tray uses rubber rollers. The conveyor motor at one end of the rubber rollers drives the rubber rollers to rotate. The rubber rollers can clamp the seed paper and move the seed paper. Since the limiting plate is located between the two sets of rubber rollers, it can support the seed paper. The gap between the limiting plates allows the rodless cylinder to drive the cutter to cut the seed paper. After the seed paper is cut, the rear rubber roller can transport the seed paper to the top of the seedling tray under the drive of the conveyor motor. At the same time, the front rubber roller can transport the seed paper to the top of the limiting plate under the drive of the conveyor motor. One end of the seed paper can move between the rear rubber rollers under the support of the limiting plate to facilitate the next cutting. Attached Figure Description

[0027] 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.
[0028] Please see Figure 1-6 This utility model provides a technical solution: a rice printing and seeding machine that can quickly determine the position of the seedling tray, including a support frame 1, a limiting roller 11 movably installed at the rear end of the support frame 1, and a printing mechanism 2 arranged above the support frame 1.
[0029] The limiting component 21 includes a support plate 211 fixedly installed above the support frame 1, a limiting frame 212 fixedly installed above the support plate 211, an adjusting cylinder 213 fixedly installed below the limiting frame 212, a movable block 214 fixedly installed at the bottom end of the adjusting cylinder 213, and a guide roller 215 movably installed on one side of the support plate 211 and the movable block 214.
[0030] Specifically, the support frame 1 can support the printing mechanism 2, the limiting roller 11 can limit the position of the seed paper roller, the support plate 211 can limit the position of the guide roller 215, the guide roller 215 can limit the movement path of the seed paper, the limiting frame 212 can limit the position of the top of the adjusting cylinder 213, and the adjusting cylinder 213 can drive the movable block 214 and the guide roller 215 on one side of the movable block 214 to move downward, thereby adjusting the relative position between the guide roller 215 on one side of the movable block 214 and the guide rollers 215 on both sides installed on one side of the support frame 1 to control the tension of the seed paper.
[0031] The conveying assembly 22 is disposed above the support frame 1 for conveying seeds. The conveying assembly 22 includes a receiving hopper 221 fixedly installed on one side of the support plate 211. A conveying pipe 222 is fixedly installed at the bottom center of the receiving hopper 221. A grain suction machine 223 is fixedly installed at the top of the conveying pipe 222. A feeding pipe 224 is fixedly installed below the grain suction machine 223. The conveying assembly 22 also includes a movable plate 225 movably installed between the support plates 211. Support springs 226 are inserted at the four corners of the movable plate 225. A vibration motor 227 is fixedly installed at the bottom of the movable plate 225.
[0032] Specifically, the receiving hopper 221 can hold a certain amount of seeds. The receiving hopper 221 is bucket-shaped with a concave center, which facilitates the entry of seeds into the conveying pipe 222. The air inside the conveying pipe 222 is discharged by the grain suction machine 223 at the top of the conveying pipe 222, and the seeds are sucked into the conveying pipe 222 and discharged into the feeding pipe 224. Since the opening at the bottom of the feeding pipe 224 is a long and thin strip, it can limit the amount of seeds discharged, so that the seeds accumulate inside the feeding pipe 224, thereby making the seeds more evenly distributed on the surface of the seed-binding paper. At the same time, the movable plate 225 is installed at an angle between the support plates 211, with its top surface pointing towards the feeding pipe 224. Driven by the vibration motor 227, the movable plate 225 will vibrate, applying an upward force to the seeds above the seed-binding paper, so that the seeds are evenly distributed on the surface of the seed-binding paper. Seeds that are not stuck by the adhesive will be discharged into the receiving hopper 221 at the bottom of the movable plate 225 with the vibration.
[0033] The dispensing assembly 23 is located above the support frame 1 for dispensing adhesive onto the seed paper. The dispensing assembly 23 includes a support roller 231 movably mounted on one side of the support plate 211, a dispensing roller 232 movably mounted above the support roller 231, a gear 233 movably mounted on the top of the support plate 211, and a stepper motor 234 on one side of the support plate 211. A glue delivery tube 235 is fitted onto one side of the support plate 211, and a partition 236 is provided below the dispensing roller 232.
[0034] Specifically, the support roller 231 can restrict the position of the dispensing roller 232. The outer side of the dispensing roller 232 is provided with an array of annular openings evenly distributed on the left and right, and the two ends are provided with toothed structures. The toothed structures at both ends of the dispensing roller 232 mesh with the gear 233. When the stepper motor 234 drives the gear 233 to rotate, the dispensing roller 232 can be driven to rotate through the gear 233. The bottom end of the glue delivery tube 235 contacts the inner wall of the dispensing roller 232, which can restrict the glue from being discharged from the dispensing roller 232 through the opening structure and contacting the seed paper, so that the glue is evenly distributed in dots above the seed paper. The partition plate 236 can restrict the position of the seed paper so that the outer side of the dispensing roller 232 can maintain contact with the seed paper.
[0035] The cutting assembly 24 is disposed above the support frame 1 for cutting the seed paper. The cutting assembly 24 includes a connecting frame 241 fixedly installed above the support frame 1. A rubber roller 242 is movably installed on the inner side of the connecting frame 241. A conveyor motor 243 is fixedly installed at one end of the rubber roller 242. A rodless cylinder 244 is fixedly installed above the connecting frame 241. A cutter 245 is fixedly installed below the slider of the rodless cylinder 244. A limit plate 246 and a guide plate 247 are fixedly installed on the inner side of the connecting frame 241. Limit cylinders 248 are fixedly installed at both ends of the connecting frame 241. A transmission plate 249 is fixedly installed at the end of the limit cylinder 248. A fixing plate 2410 is movably installed on one side of the transmission plate 249. Limit springs 2411 are inserted through both sides of the fixing plate 2410.
[0036] Specifically, the connecting frame 241 restricts the position of the rubber roller 242. The conveying motor 243 at one end of the rubber roller 242 drives the rubber roller 242 to rotate. The rubber roller 242 clamps the seed paper and moves it. Since the limiting plate 246 is located between the two sets of rubber rollers 242, it supports the seed paper. The gap between the limiting plates 246 allows the rodless cylinder 244 to drive the cutter 245 to cut the seed paper. After the seed paper is cut, the rear rubber roller 242, driven by the conveying motor 243, transports the seed paper to the top of the seedling tray. Simultaneously, the front rubber roller 242... Driven by motor 243, the seed paper is conveyed to the top of the limiting plate 246. One end of the seed paper can move between the rear rubber rollers 242 under the support of the limiting plate 246 to facilitate the next cutting. The limiting cylinder 248 is mirror-symmetrically installed on both sides of the connecting frame 241. The limiting cylinder 248 drives the transmission plate 249 to move, so that the fixed plate 2410 on one side of the transmission plate 249 on both sides of the connecting frame 241 contacts the seedling tray and squeezes the limiting spring 2411. Due to the principle of force balance, the contraction of the limiting springs 2411 on both sides is the same, thereby restricting the seedling tray to the center of the connecting frame 241 to quickly determine the position of the seedling tray.
[0037] Specifically, the models of the adjusting cylinder 213 and the limiting cylinder 248 are SCA2-00-50B-70, the model of the grain suction machine 223 is MA-165, the model of the vibration motor 227 is YZD-20-6, and the model of the stepper motor 234 is 86BYG. In addition, all contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0038] During operation, the movable plate 225 is installed at an angle between the support plates 211, with its top surface pointing towards the feeding pipe 224. Driven by the vibrating motor 227, the movable plate 225 vibrates, applying an upward force to the seeds above the seed-binding paper to ensure even distribution of the seeds on the surface of the seed-binding paper. Seeds not bound by the adhesive are discharged from the bottom of the movable plate 225 into the receiving hopper 221, allowing excess seeds above the seed-binding paper to be collected by the receiving hopper 221. The movable plate 225 also provides support for the seed-binding paper, preventing it from breaking under the weight of the seeds. The conveying motor 243 at one end of the rubber roller 242 drives the rubber roller 242 to rotate. The rubber roller 242 can clamp the seed paper and drive it to move. Since the limiting plate 246 is located between the two sets of rubber rollers 242, it can support the seed paper. The gap between the limiting plates 246 can facilitate the rodless cylinder 244 to drive the cutter 245 to cut the seed paper. After the seed paper is cut, the rear rubber roller 242 can transport the seed paper to the top of the seedling tray under the drive of the conveying motor 243. At the same time, the front rubber roller 242 can transport the seed paper to the top of the limiting plate 246 under the drive of the conveying motor 243. One end of the seed paper can move between the rear rubber rollers 242 under the support of the limiting plate 246 to facilitate the next cutting.
