[0002] At present, the existing pepper seedling transplanting equipment in my country is not perfect in the automation design of the pepper seedling transplanting process. The first problem is that the pepper seedling transplanting process is cumbersome, and multiple automated equipment are required to complete the transplanting of pepper seedlings, and the cost of agricultural mechanization is relatively high. Secondly, the automatic equipment for transplanting pepper seedlings has different specifications and cannot cooperate with each other. Sometimes there is a ridge formed by a ridging machine, and another transplanting machine cannot perform the transplanting work well on it. Due to technical reasons, another problem with the automated transplanting of pepper seedlings is that some links cannot be completely separated from manual labor. The need for manual control undoubtedly increases the cost of agricultural planting and also puts forward requirements on the technical level of migrant workers. Therefore, although the overall mechanization level of automated transplanting of pepper seedlings in my country is already relatively high, it is still incomplete and cannot fully liberate productivity.

[0003] At present, for the transplanting of pepper seedlings, since the pepper seedlings are small, they are transplanted in the karst area of ​​Guizhou. Because the soil is compacted and contains a lot of gravel, the problem can be effectively solved by installing a gravel device on the front side of the transplanter. However, the existing transplanting mechanism uses a duckbill to open during transplanting, and uses an externally arranged driving mechanism to drive the duckbill to open. In this method, when the duckbill is separated, the soil falls back, affecting the placement stability of the internal pepper seedlings, and it is inconvenient to arrange the driving mechanism on the outside. Summary of the invention

The shovel plate 701 is tilted and fixedly connected to the front side of the crushing frame 705, and the crushing roller 1 702 and the crushing roller 2 703 are rotatably connected to the crushing frame 705 up and down through the bearing seat and the symmetric surface is close to the high end of the shovel plate 701, and the same After the end extends out of the bearing seat, it is connected to a meshing gear of the same size, one of which is connected to the axle of the front walking wheel through a sprocket chain mechanism to reduce the layout of the power mechanism. The crushing roller 702 and the crushing roller 703 are both provided with staggered crushing teeth 706. Two ridging plates 704 are used, which are respectively installed on both sides of the rear of the crushing machine frame 705 through a fixed frame 707 to form ridges for the soil after crushing. In the karst area, the soil contains more gravel, which affects the ridging, planting and growth of peppers. By crushing the gravel in the soil before ridging, the quality of ridging is not affected, and it does not affect the hole making of the transplanter during planting and avoid affecting the transplanting and growth of peppers. In order to avoid the impact of the crushing roller and improve safety, a protective cover 711 is installed above the crushing frame 705. The two crushing rollers mesh with each other to crush the stones. In view of the serious compaction of Guizhou's clay soil and the large amount of stones, the purpose of crushing the soil is achieved, which is convenient for the better growth of peppers and increases the yield of peppers. The soil after crushing is used for ridge and furrowing by the ridge-forming plate 704. Working principle: During the movement of the frame, the compacted soil is shoveled up by the shovel plate 701 at the front end, and the soil is pushed into the space between the two crushing rollers for crushing during the movement. After crushing, it falls to the rear side and ridges are formed under the action of the ridge-forming plate. After ridge formation, the film covering operation is performed.

[0056] Among them, the walking mechanism includes a front power walking wheel 8 and a rear walking wheel 9. The wheel axle of the front power walking wheel 8 is connected to the diesel engine 10 through a transmission mechanism, and the walking is stable and reliable.

[0057] In order to improve the stability of the seedlings after transplanting, a double buried soil wheel 11 is provided on the rear side of the frame 1. The double buried soil wheel 11 is symmetrically arranged on both sides of the crank slider transplanting mechanism 5, and is used to cover the soil after transplanting the pepper seedlings. When the double buried soil wheel 11 is provided, when the transplanting mechanism completes the transplanting work, the double buried soil wheel 11 moves forward with the entire device, driving the soil left on the film to ridge into the transplanting hole, helping the pepper seedlings to achieve stability, not to fall over, and increase the yield.

[0058] A camera is installed in front of the frame 1 to transmit the working status and current road conditions in real time. The machine can analyze the farming process autonomously, and the farmer can also remotely control the operation of the machine and monitor the farming status of the machine in real time through the camera. Farming is no longer restricted by time and space. No matter where they are, the farmer can control the working status of the machine at any time. This improves the convenience of manpower and the efficiency of mechanical labor, and improves the flexibility and convenience of farming.

[0059] The degree of land fragmentation in Guizhou is serious, and irregularly shaped land is difficult to cultivate. By setting up a 3D laser scanning module and image recognition algorithm, the transplanter can identify the land conditions in advance to build a three-dimensional land model, and plan the path based on the model. It plans the path for different shapes and uploads the plan to the monitor at the same time, so that the path can be adjusted manually. The labor cost is completely eliminated, and all transplanting tasks can be completed without human participation. Traditional transplanting requires human participation and the accuracy needs to be verified. Therefore, by adding an algorithm recognition design to the transplanting device, the transplanting distance can be automatically adjusted, ensuring the efficiency and accuracy of transplanting.

[0060] The integrated pepper seedling transplanter is mainly composed of six parts: breaking and ridging mechanism, film covering mechanism, crank slider transplanting mechanism, seedling feeding conveyor, seedling taking robot and ridge returning device. In addition, there are seedling tray storage rack and empty seedling tray recovery frame.

[0061] The crushing and ridging mechanism is installed at the front end of the frame. It is a soil-raising device. After the front end is inserted into the soil, the soil blocks are pushed along the groove to between the two meshing double-twisted crushing rollers. The soil is crushed by the rotating meshing crushing rollers into a softer soil and falls into the rear. The rear is equipped with ridging plates, which are used to shape the ridge surface.

[0062] The film covering mechanism uses the friction between the film and the soil and the film pressing wheel to pull out the film on the grinding roller. The film is shaped by the front film pressing roller to flatten the film and cover it on the ridge surface. The film pressing wheel presses the film on both sides into the soil while passing through the film pressing roller, and the soil is gathered to the film and fixed with a paddle. At the same time, part of the soil is ridged into the hollow drum, and the drum compacts the covered film. Then the soil leaks out through the circular holes in the drum at equal intervals, and is used for the soil fixing device to ridge the soil to fix the roots of the seedlings during subsequent transplanting.

[0063] The double sleeve transplanting device (crank slider transplanting mechanism 5) has inner and outer double sleeves that reciprocate, the outer sleeve first makes a hole, and then the inner sleeve moves down to push open the claws of the duckbill to release the pepper seedlings, so that the pepper seedlings can be smoothly planted into the soil.

[0064] The seedling feeding conveyor is fixed by a seedling storage grid formed by a connecting rod and a sprocket. It is equipped with dual stepping motors to realize forward, backward, left and right movement, and cooperate with the seedling retrieval robot. After the seedling retrieval robot detects the pepper seedlings in the specified position through infrared, it drives the claw to move through the crank slider. The claw is closed when the opening and closing drive plate is in the middle of the curved waist-shaped groove, and is opened when it is at both ends, thereby realizing the seedling grabbing and feeding process.

[0065] The ridge return device (double buried soil wheels) consists of two wheels, which push the soil originally placed on the film to the roots of the seedlings, thereby fixing the seedlings and ensuring that the transplanted seedlings are resistant to lodging.

[0066] Operation method: During the movement of the frame, the soil is broken and ridged by the crushing and ridging mechanism, and the film covering mechanism is used for film covering after ridging. After film covering, holes are made for transplanting. When the frame moves to the starting position, the seedling tray of the pepper seedlings is first placed on the feeding conveyor for delivery. When the leftmost row reaches the left end and is in a suspended state, two seedling manipulators grab the pepper seedlings at the corresponding two positions and place them in two transplanting devices (crank slider transplanting mechanism). Two seedlings are transplanted at one time to achieve the planting of two seedlings. When the frame moves to the next position and performs the next grabbing, it is necessary to control the feeding conveyor to move horizontally to the second position of the first row of seedling trays to grab the next pepper seedling and put it into the corresponding transplanting device for transplanting. Repeat the horizontal movement of the feeding conveyor for multiple times. After the pepper seedlings in the first row of seedling trays are planted, the feeding conveyor returns to the starting position, and the second row of seedling trays are controlled to perform the next round of seedling manipulators and transplanting devices to repeat the movement and planting. After multiple rounds of repeated actions, the planting of all pepper seedlings on the entire seedling tray is completed.
