Description

Technical Field

[0001] This utility model relates to the field of transplanter seedling replenishment technology, and more specifically, to a transplanter seedling replenishment device suitable for biodegradable plug seedlings. Background Technology

[0002] The technology of seedling tray cultivation and mechanized transplanting of seedling trays plays a crucial role in promoting the development of my country's vegetable and fruit industry. Seedling transplanting technology can not only increase the multiple cropping index, but also effectively reduce the impact of pests, diseases and weeds, thereby improving the yield and quality of fruits and vegetables. Current transplanting operations mainly rely on manual transplanting and semi-automatic transplanting technologies. Although semi-automatic transplanting technology is more adaptable to seedling trays, it still requires manual handling of seedling removal and feeding, while transplanting machines are only responsible for completing the automatic planting action.

[0003] During the use of fully automatic transplanters, the problem of missed planting is particularly prominent, mainly manifested as planting inferior seedlings and no seedlings at all. The main reasons for the missed planting problem can be summarized as follows: First, the seedling stage is affected by multiple factors such as seed quality, sowing accuracy, and seedling management, leading to the phenomenon of no seedlings, thus resulting in missed planting during transplanting; Second, potted seedlings may be damaged by mechanical forces or fall off during packaging and transportation, resulting in missing or inferior seedlings, which presents as missed planting during transplanting; Finally, during the field transplanting stage, due to failure in seedling picking and placing operations or damage to seedlings, missed planting may occur during transplanting. In order to replenish the empty seedling cups after removing inferior seedlings during transplanting, a seedling replenishment device is needed. Existing seedling replenishment methods rely on manual replenishment, which is inefficient and may lead to worker fatigue due to long-term operation, further aggravating operational errors and causing secondary missed planting. Therefore, a seedling replenishment device suitable for biodegradable plug seedling transplanters is proposed. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a transplanting machine seedling replenishment device suitable for biodegradable plug seedlings, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a transplanter seedling replenishment device suitable for biodegradable plug seedlings, comprising two side plates mounted on an automatic transplanter, a conveyor belt disposed between the two side plates, multiple conveyor belt baffles fixedly connected to the outer surface of the conveyor belt, multiple plug seedlings with biodegradable plug trays placed on the top of the conveyor belt, a servo motor fixedly connected to one end of one of the side plates, and starting the servo motor controls the conveyor belt to move the conveyor belt baffles a fixed distance, so that the biodegradable plug seedlings between the two conveyor belt baffles can be sequentially transported to the position of the seedling delivery tube, thereby replenishing seedlings to empty seedling cups below through the seedling delivery tube;

[0006] A seedling replenishment groove is provided on the top of the side closest to the servo motor between the two side plates. An inclined plate is fixedly connected to the top of the side away from the servo motor between the two side plates. A seedling placement square tube is fixedly connected to the side of the side plate close to the inclined plate. A first diffuse reflection photoelectric sensor is inserted into the end of one of the side plates away from the servo motor. The seedling replenishment groove facilitates manual replenishment. The inclined plate can adjust the posture of the seedling before it falls to ensure that it does not deviate or flip. The seedling placement square tube facilitates stable falling to the middle of the bottom seedling cup. The first diffuse reflection photoelectric sensor can detect whether there is a biodegradable seedling in the seedling placement square tube. When no seedling is detected at this position, the servo motor will drive the conveyor belt to rotate continuously until a biodegradable seedling is detected. The servo motor will then stop, thus ensuring that there is always a high-quality seedling falling into the empty seedling cup below.

[0007] A support plate is fixedly connected to one side of the seedling tray, and a second diffuse reflection photoelectric sensor is inserted into one end of the support plate. An opening and closing mechanism is provided at the bottom of the seedling tray, and a seedling cup is provided at the bottom of the seedling tray. The second diffuse reflection photoelectric sensor detects whether an empty seedling cup moves to the bottom of the seedling tray, and the opening and closing mechanism facilitates accurate replanting.

[0008] Preferably, the output end of the servo motor is fixedly connected to one end of the conveyor belt shaft, and the width of the conveyor belt is the same as the distance between the two side plates. Starting the servo motor controls the rotation of the conveyor belt for convenient transport.

[0009] Preferably, the biodegradable seedling trays are placed between two adjacent conveyor belt baffles, with the end of the inclined plate closer to the seedling tube lower than the other end. The biodegradable seedling trays are made of starch-based materials, biomass fiber materials, or polylactic acid materials. The movement of the conveyor belt baffles moves the biodegradable seedling trays, and the inclined plate can adjust the conveying posture of the seedling trays to ensure that they do not deviate or overturn. Furthermore, the biodegradable seedling trays allow the seedlings to be transplanted without being removed from the trays during transplanting, and the trays can be transplanted into the soil as a whole. The trays gradually degrade in the natural environment and are absorbed by the soil, making it a green and environmentally friendly seedling cultivation method.

[0010] Preferably, the cavity between the two side plates is the same as one side wall of the seedling tray. The first diffuse reflection photoelectric sensor is located directly below the inclined plate, which facilitates the delivery of the biodegradable seedling tray to the middle of the seedling tray. The first diffuse reflection photoelectric sensor senses whether there are biodegradable seedlings about to fall into the middle of the seedling tray, so that the biodegradable seedlings are stably dropped into the empty seedling cup below in an upright posture through the seedling tray.

[0011] Preferably, the opening and closing mechanism includes a push-pull electromagnet fixed to one side of the seedling tray, and supporting inclined plates are symmetrically fixed to both sides of the seedling tray. A first opening plate and a second opening plate are respectively provided on both sides of the bottom of the seedling tray.

[0012] Preferably, both ends of the top of the first opening plate and the second opening plate are fixedly connected to connecting cylinders, and the connecting cylinders are rotatably connected to the supporting inclined plate through a rotating shaft. A connecting rod is fixedly connected to the top of one of the connecting cylinders on the top of the first opening plate.

[0013] Preferably, the top of the connecting rod is rotatably connected to a combined connecting rod via a rotating shaft, and a connecting ring is fixedly connected to the middle of one side of the second opening plate. One end of the combined connecting rod is rotatably connected to the connecting ring. The output end of the push-pull electromagnet is rotatably connected to the connecting shaft of the connecting rod and the combined connecting rod. When the push-pull electromagnet is energized, it retracts and drives the top of the connecting rod to rotate, which can push the combined connecting rod, thereby moving the bottom ends of the first and second opening plates to opposite sides to achieve the opening function, facilitating the replanting of seedlings into empty seedling cups below.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] This invention firstly utilizes a biodegradable seedling tray, allowing the seedlings grown in pots to be transplanted without being removed from the tray. The seedlings can be transplanted into the soil along with the tray. The tray gradually degrades in the natural environment and is absorbed by the soil. A servo motor is activated to control the rotation of the conveyor belt. The movement of the conveyor belt baffles moves the biodegradable seedlings until they reach the middle of the seedling tray. By controlling the opening and closing mechanism, the seedlings with biodegradable trays can be moved into the seedling cups directly below, achieving automatic seedling replenishment and ensuring the accuracy of seedling replenishment.

[0016] This invention also features an inclined plate that adjusts the conveying posture of the biodegradable seedling trays to ensure they do not deviate or flip. A first diffuse reflection photoelectric sensor detects whether a seedling with a biodegradable tray is about to fall into the middle of the seedling tray. When no seedling is detected at that position, a servo motor drives the conveyor belt to rotate continuously until a replacement biodegradable seedling is detected. This ensures that a high-quality seedling always falls into the empty seedling cup below. A second diffuse reflection photoelectric sensor detects whether an empty seedling cup moves towards the bottom of the seedling tray for easy replenishment.

[0017] In summary, through the interaction of the above-mentioned multiple functions, by detecting whether there are empty seedling cups moving towards the bottom of the seedling tray, the servo motor and opening / closing mechanism, in conjunction with the first diffuse reflection photoelectric sensor, are activated to control a seedling with a biodegradable tray to move to the middle of the seedling tray, thereby automatically falling into the corresponding seedling cup and achieving the function of automatic seedling replenishment.

[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] As attached Figure 1 , 2 The transplanter seedling replenishment device shown includes two side plates 1 on an automatic transplanter, a conveyor belt 2 between the two side plates 1, multiple conveyor belt baffles 3 fixedly connected to the outer surface of the conveyor belt 2, and multiple seedlings 5 ​​with biodegradable seedling trays 4 placed on the top of the conveyor belt 2. A servo motor 8 is fixedly connected to one end of one of the side plates 1. When the servo motor 8 is started, the conveyor belt 2 is controlled to move the conveyor belt baffles 3 a fixed distance, so that the seedlings 5 ​​with biodegradable seedling trays 4 between the two conveyor belt baffles 3 can be transported sequentially to the position of the seedling feeding tube 10, thereby replenishing the seedlings through the seedling feeding tube 10.

[0025] A seedling replenishment groove 6 is provided on the top of the side closest to the servo motor 8 between the two side plates 1. An inclined plate 7 is fixedly connected to the top of the side away from the servo motor 8 between the two side plates 1. A seedling placement tube 10 is fixedly connected to the side of the side plate 1 close to the inclined plate 7. A first diffuse reflection photoelectric sensor 9 is inserted into the end of one of the side plates 1 away from the servo motor 8. The seedling replenishment groove 6 facilitates manual replenishment. The inclined plate 7 can adjust the posture of the seedling before it falls to ensure that it does not deviate or flip. The seedling placement tube 10 facilitates stable falling to the middle of the bottom seedling cup 13. The first diffuse reflection photoelectric sensor 9 can detect whether a seedling 5 with a biodegradable seedling tray 4 has moved to the position of the seedling placement tube 10. When no seedling is detected at this position, the servo motor 8 will drive the conveyor belt 2 to rotate continuously until a seedling 5 with a biodegradable seedling tray 4 is detected. The servo motor 8 will then stop, thus ensuring that there is always a high-quality seedling falling into the empty seedling cup below.

[0026] A support plate 11 is fixedly connected to one side of the seedling tray 10. A second diffuse reflection photoelectric sensor 12 is inserted into one end of the support plate 11. An opening and closing mechanism is provided at the bottom of the seedling tray 10. A seedling cup 13 is provided at the bottom of the seedling tray 10. The second diffuse reflection photoelectric sensor 12 detects whether there is an empty seedling cup 13 moving towards the bottom of the seedling tray 10. The opening and closing mechanism facilitates accurate seedling replenishment.

[0027] As attached Figure 3 As shown, the output end of the servo motor 8 is fixedly connected to one end of the shaft of the conveyor belt 2. The width of the conveyor belt 2 is the same as the distance between the two side plates 1. The biodegradable seedling tray 4 is set between two adjacent conveyor belt baffles 3. The end of the inclined plate 7 near the seedling tube 10 is lower than the other end. The material of the biodegradable seedling tray 4 is starch-based material, biomass fiber material, or polylactic acid material. The cavity between the two side plates 1 is the same as one side wall of the seedling tube 10. The first diffuse reflection photoelectric sensor 9 is located on the side directly below the inclined plate 7. The servo motor 8 is started to control the rotation of the conveyor belt 2 for convenient transportation. The movement of the conveyor belt baffles 3 drives the seedlings 5 ​​with biodegradable seedling trays 4 to move. The inclined plate 7 can adjust the conveying posture of the seedlings in the plug tray to ensure that they do not deviate or overturn. The biodegradable plug tray 4 allows the seedlings to be transplanted without being removed from the plug tray during the transplanting process. The plug tray can be transplanted into the soil as a whole. The plug tray gradually degrades in the natural environment and is absorbed by the soil, which is a green and environmentally friendly seedling cultivation method. It is convenient to transport the seedlings 5 ​​with biodegradable plug tray 4 to the middle of the seedling delivery tube 10. The first diffuse reflection photoelectric sensor 9 senses whether there is a seedling 5 with biodegradable plug tray 4 about to fall into the middle of the seedling delivery tube 10. Then, the seedling delivery tube 10 will stably drop the seedling 5 with biodegradable plug tray 4 into the empty seedling cup below in an upright posture.

[0028] As attached Figure 2 , 4As shown, the opening and closing mechanism includes a push-pull electromagnet 20 fixed to one side of the seedling tray 10. Supporting inclined plates are symmetrically fixed to both sides of the seedling tray 10. A first opening plate 14 and a second opening plate 15 are respectively provided on both sides of the bottom of the seedling tray 10. Connecting cylinders 16 are fixedly connected to the top ends of both the first opening plate 14 and the second opening plate 15. The connecting cylinders 16 are rotatably connected to the supporting inclined plates via a rotating shaft. A connecting rod 17 is fixedly connected to the top of one of the connecting cylinders 16 on the top of the first opening plate 14. The first opening plate 14 and the second opening plate 15 are rotatably connected to a combined connecting rod 18 via a rotating shaft. A connecting ring 19 is fixedly connected to the middle of one side of the second opening plate 15. One end of the combined connecting rod 18 is rotatably connected to the connecting ring 19. The output end of the push-pull electromagnet 20 is rotatably connected to the connecting shaft of the connecting rod 17 and the combined connecting rod 18. When the push-pull electromagnet is energized, it retracts and drives the top end of the connecting rod 17 to rotate, which can push the combined connecting rod 18, thereby moving the bottom ends of the first opening plate 14 and the second opening plate 15 to the opposite side, realizing the opening function and facilitating the use of replanting seedlings.

[0029] It is worth noting that the servo motor 8, the first diffuse reflection photoelectric sensor 9, the second diffuse reflection photoelectric sensor 12, and the push-pull electromagnet 20 are all connected to the control system and power system of the automatic transplanter for convenient control and use.

[0030] The automatic transplanter described in this application document, as attached... Figure 1 The structure shown refers to the automatic transplanter used in the application CN202510601735.8 entitled "A top-pot-grafting low-damage seedling taking device for an automatic transplanter and its working method". It is existing technology, and its working principle and specific structure will not be elaborated here.

[0031] The working principle of this utility model is as follows: When in use, the second diffuse reflection photoelectric sensor 12 detects whether the seedling cup 13 conveyed below is empty. When it is detected that the cup is empty, the servo motor 8 pushes and pulls the electromagnet 20. The servo motor 8 controls the conveyor belt 2 to move the seedling 5 with the biodegradable tray 4, so that the seedling 5 with the biodegradable tray 4 corresponds with the first diffuse reflection photoelectric sensor 9. At this time, the inclined plate 7 can correct the posture of the seedling 5 with the biodegradable tray 4 until the seedling 5 with the biodegradable tray 4 moves to the middle of the seedling tube 10.

[0032] At the same time, the push-pull electromagnet 20 pulls the connecting rod 17 to control the first opening plate 14 and the second opening plate 15 to open the bottom of the seedling tray 10. The seedlings 5 ​​with biodegradable trays 4 that have entered the seedling tray 10 will automatically fall into the middle of the seedling cup 13 directly below, realizing the function of replanting seedlings.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
