Description

Technical Field

[0001] This utility model relates to the field of vegetable transplanting technology, specifically a chain-type automatic vegetable transplanting mechanism. Background Technology

[0002] Vegetable production is a labor-intensive industry, and seedling transplanting is a crucial step in the process. Traditional manual transplanting methods are outdated, inefficient, labor-intensive, and cannot complete large-scale transplanting in a short time. Therefore, to reduce labor consumption, improve transplanting quality and efficiency, and achieve mechanization of vegetable planting has become an urgent need in agricultural production.

[0003] Currently, the main types of vegetable transplanter planters in China include chain clamp type, seedling guide tube type, eccentric disc rotating basket type, and flexible disc type. Among them, the chain clamp type planter is only used for bare seedling transplanting and requires manual feeding of seedlings. The clamps can easily damage the seedlings, and the operating speed is low. The seedling guide tube type planter has a relatively complex structure, and the potted seedlings fall freely into the trench, making it difficult to guarantee the planting quality. The eccentric disc rotating basket type planter cannot feed seedlings at too high a speed, otherwise the rate of missed planting will increase, and the vibration is large when the planting frequency is slightly higher, resulting in low productivity. The flexible disc type planter has a short disc life and unstable planting depth, and can only be used for densely planted bare seedlings. The traditional planter has a low transplanting frequency and cannot be selected as a high-speed automatic transplanter planter.

[0004] Chinese patent discloses a chain-driven hanging cup-type seedling planter and its transplanting method (authorization announcement number CN104919953B). This patented technology features a vertically arranged transmission chain and hanging cups mounted on the transmission chain on a frame, reducing the horizontal volume of the planter and making its installation more flexible and convenient. The seedling planting assembly adopts a unique hanging cup structure; during planting, the duckbill opens and closes perpendicular to the planter's forward direction, protecting the seedlings from mechanical damage. The chain drive propels the seedling planting assembly, and the track control assembly uses a combination of rollers and a circular track to maintain the assembly's vertical posture, ensuring smooth transmission and facilitating high-speed seedling transplanting. The hanging cups are evenly distributed on the transmission chain, and adjusting the number of cups allows for the transplanting of different varieties and specifications of seedlings.

[0005] However, it has certain drawbacks: the drive chain is exposed and close to the ground during use, so hard impurities such as gravel can easily adhere to its surface during long-term operation. These impurities increase the friction between the chain and the sprocket, causing the chain to wear faster and resulting in significant shaking during operation. This, in turn, causes the duckbill to shake significantly, affecting the accuracy of transplanting. Furthermore, over time, the chain may break due to excessive wear, affecting the normal operation of the transplanting mechanism and increasing maintenance costs. Utility Model Content

[0006] The purpose of this invention is to provide a chain-type automatic vegetable transplanting mechanism to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A chain-type automatic vegetable transplanting mechanism includes a support plate, a first motor fixedly connected to the upper end of the rear surface of the support plate, and sprockets rotatably connected and fixedly connected to the lower end of the front surface of the support plate and the output end of the first motor, respectively. A chain is meshed with the outer sides of the two sprockets, and a transplanting mechanism is provided on the surface of the chain.

[0009] The front surface of the support plate, located inside the chain, and the rear surface are both equipped with a cleaning mechanism. The cleaning mechanism includes a wind seat, a fixing plate fixed to the lower end of the wind seat, a fan fixed to the upper end of the wind seat, a wind hood fixed to the upper end of the fan, a duct fixed to the upper surface of the duct, a spray pipe fixed to the upper end of the duct, a filter plate fixed to the left side surface of the wind seat, and a protective component inside the filter plate.

[0010] As a further embodiment of this utility model: the transplanting mechanism includes a seedling tube, a first connecting rod rotatably connected to the rear surface of the seedling tube, and two second connecting rods symmetrically rotatably connected to the front and rear surfaces of the seedling tube below the first connecting rod. A duckbill is fixedly connected to the exterior of both the front and rear second connecting rods. A first gear is fixedly connected to the exterior of the front second connecting rod in front of the duckbill. An L-shaped plate is fixedly connected to the front surface of the seedling tube above the second connecting rod. A second motor is fixedly connected to the front surface of the L-shaped plate, and a second gear is fixedly connected to the output end of the second motor.

[0011] As a further embodiment of this utility model: the protective component includes a rotating rod, an impeller is fixedly connected to the right end of the rotating rod, and a brush plate is fixedly connected to the left end of the rotating rod.

[0012] As a further embodiment of this utility model: the front end of the fixing plate is fixed to the rear surface of the support plate, the air duct is connected through the support plate, the nozzle is fixed to the front surface of the support plate, and the nozzle is located inside the chain.

[0013] As a further embodiment of this utility model: the first connecting rod is fixed to the chain, the duckbill is located outside the seedling tube, the two first gears mesh with each other, and the second gear meshes with the left first gear.

[0014] As a further embodiment of this utility model: the rotating rod is rotatably connected to the filter plate, and the brush plate is attached to the left side surface of the filter plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model is equipped with a transplanting mechanism. The first motor drives the chain to rotate, and the chain drives the transplanting mechanism to rotate. When the transplanting mechanism moves to the appropriate position, the second motor drives the second gear to rotate counterclockwise, so that the two duckbill openings open and the vegetable seedlings are put down, thus realizing the automatic transplanting function of vegetables.

[0017] 2. This utility model incorporates a cleaning mechanism. A fan in the cleaning mechanism draws air from the outside, and the airflow is sprayed through a nozzle to clean the chain, blowing off hard impurities such as stones from the chain surface. This prevents the chain from being worn down by adhering to these hard impurities, which could eventually lead to chain breakage or sprocket damage. The filter plate is used for air intake and filtering of dust and impurities. When the airflow enters the fan seat, it impacts the impeller, causing it to rotate, which in turn drives the brush plate to rotate and clean the filter plate, preventing clogging.

A first motor 2 is fixedly connected to the upper end of the rear surface of the support plate 1. A sprocket 3 is rotatably connected and fixedly connected to the lower end of the front surface of the support plate 1 and the output end of the first motor 2, respectively. A chain 4 is meshed with the outer sides of the two sprockets 3. A transplanting mechanism 5 is provided on the surface of the chain 4. The transplanting mechanism 5 includes a seedling tube 6. A first connecting rod 7 is rotatably connected to the rear surface of the seedling tube 6. The first connecting rod 7 is fixedly connected to the chain 4, and the front and rear sides of the seedling tube 6 are located on the first connecting rod 7. Below each of the two second connecting rods 8 are symmetrically rotatably connected. The outside of the two second connecting rods 8 are fixedly connected to the duckbill 9. The duckbill 9 is located outside the seedling tube 6. The outside of the front second connecting rod 8 is fixedly connected to the duckbill 9. The two first gears 10 mesh with each other. The front surface of the seedling tube 6 is fixedly connected to the L-shaped plate 11 above the second connecting rod 8. The front surface of the L-shaped plate 11 is fixedly connected to the second motor 12. The output end of the second motor 12 is fixedly connected to the second gear 13. The second gear 13 meshes with the left first gear 10.

[0024] Support plate 1 is installed on a drive device, such as a seedling truck;

[0025] The first motor 2 is used to drive the chain 4 to rotate via the sprocket 3;

[0026] The transplanting mechanism 5 is fixed to the chain plate of the chain 4 by the first connecting rod 7; its initial position is located at the upper right of the support plate 1, which is used to place the vegetable seedlings inside the transplanting mechanism 5; the transplanting mechanism 5 has enough weight to keep it upright at all times.

[0027] The number of transplanting mechanisms 5 can be increased as needed, and is not limited to one shown in the diagram;

[0028] A sensor is fixedly connected to the lower end of the support plate 1 to detect the transplanting mechanism 5. When the transplanting mechanism 5 moves to the lower position, the two duckbill 9 open and put down the vegetable seedlings.

[0029] The speed of the first motor 2 is appropriate to avoid excessive speed causing large-scale shaking of the transplanting mechanism 5;

[0030] The second motor 12 is connected to an external control system. When it drives the second gear 13 to rotate counterclockwise, the left first gear 10 will rotate clockwise and the right first gear 10 will rotate counterclockwise, and the two duckbill 9 will open to put down the vegetable seedlings.

[0031] exist Figure 1 and Figure 3In the middle: the front surface of the support plate 1 is located inside the chain 4 and the rear surface are jointly provided with a cleaning mechanism 14. The cleaning mechanism 14 includes a wind seat 15. The lower end of the wind seat 15 is fixedly connected to a fixing plate 16. The front end of the fixing plate 16 is fixedly connected to the rear surface of the support plate 1. The upper end of the wind seat 15 is fixedly connected to a fan 17. The upper end of the fan 17 is fixedly connected to a fan hood 18. The upper surface of the fan hood 18 is connected to a duct 19. The duct 19 is connected to the support plate 1. The upper end of the duct 19 is fixedly connected to a spray pipe 20. The spray pipe 20 is fixedly connected to the front surface of the support plate 1 and is located inside the chain 4. The left side surface of the wind seat 15 is fixedly connected to a filter plate 21.

[0032] The blower 17 is used to draw air from the outside, so that the airflow enters the air seat 15, then enters the air duct 19, and finally sprays it out through the nozzle 20. This is used to clean the chain 4 and prevent hard impurities such as gravel from adhering to its surface, which would cause wear and eventually lead to the chain 4 breaking or the sprocket 3 being damaged.

[0033] The filter plate 21 is used for airflow entry and for filtering external dust and impurities;

[0034] The nozzle 20 includes a pipe body, fixing blocks fixed to the upper and lower ends of the pipe body, and multiple spray holes opened on the left and right sides of the pipe body; the fixing blocks are fixed to the support plate 1.

[0035] exist Figure 3 and Figure 4 In the middle: The filter plate 21 is provided with a protective component 22. The protective component 22 includes a rotating rod 23, which is rotatably connected to the filter plate 21. An impeller 24 is fixed to the right end of the rotating rod 23, and a brush plate 25 is fixed to the left end of the rotating rod 23. The brush plate 25 is attached to the left side surface of the filter plate 21.

[0036] The fan 17 has sufficient power, and the airflow it generates impacts the impeller 24 enough to drive it to rotate, thereby causing the brush plate 25 to rotate and clean the filter plate 21, thus preventing the filter plate 21 from becoming clogged.

[0037] The impeller 24 is close to the filter plate 21, but not in contact with it, so that it can better receive the impact of the airflow.

[0038] The working principle of this utility model is as follows: In use, the first motor 2 drives the chain 4 to rotate through the sprocket 3. When the transplanting mechanism 5 rotates to the lower end, the second motor 12 drives the second gear 13 to rotate counterclockwise. The left first gear 10 will rotate clockwise, and the right first gear 10 will rotate counterclockwise. The two duckbill 9 will open and put the vegetable seedling down. Then, the second motor 12 drives the second gear 13 to rotate clockwise, causing the two duckbill 9 to close. When the transplanting mechanism 5 moves to the upper right of the support plate 1, the vegetable seedlings are put into the seedling tube 6 manually or by the seedling picking mechanism. This transplanting is repeated. During this process, the fan 17 draws air from the outside, causing the airflow to enter the air seat 15, then the air duct 19, and finally sprays it out through the spray pipe 20 to clean the chain 4, blowing off the hard impurities on the surface of the chain 4. At the same time, the airflow impacts the impeller 24 to rotate, causing the brush plate 25 to clean the filter plate 21, thus preventing the filter plate 21 from clogging.
