Description

Technical Field

[0001] The invention relates to the technical field of rice transplanters, in particular to a rice seedling tray fixing mechanism of a rice transplanter. Background Art

[0002] Rice, also known as rice, rice, and paddy, is a cereal crop of the genus Oryza in the Gramineae family. Rice is one of the important food crops for mankind, and its cultivation and consumption have a long history. Half of the world's population eats rice, mainly in Asia, southern Europe, tropical America, and parts of Africa; Among them, during the rice planting process, a rice transplanter is used to plant the rice seedlings in the paddy field. The working process of the transplanter varies due to different structures, but the basic process is roughly the same. The principle of "taking the seedlings in groups and planting them directly" is: the seedlings are neatly placed in the seedling box in a group state, and move horizontally with the seedling box, so that the seedling taker takes a certain number of seedlings in a grid one by one, and under the action of the transplanting trajectory control mechanism, the seedlings are inserted into the soil according to agronomic requirements, and the seedling taker returns to the seedling box to take the seedlings according to a certain trajectory; during the use of the rice transplanter, the rice seedling tray fixing mechanism is used to fix the rice seedling tray to prevent the rice seedling tray from falling off due to the shaking generated during the operation of the rice transplanter when it is placed on the rice transplanter.

[0003] However, in actual use of the prior art, when the rice seedling tray is fixed by the rice seedling tray fixing mechanism, the rice seedling trays are usually fixed one by one, so that when the rice seedling tray is replaced, the replaced rice seedling trays need to be disassembled one by one before replacing the new rice seedling trays, which makes it inconvenient to disassemble and replace the rice seedling trays, thereby affecting the transplanting efficiency of the rice transplanter. Summary of the invention

[0004] The object of the present invention is to provide a rice seedling tray fixing mechanism for a rice transplanter, so as to solve the problem proposed in the above background technology that in the process of fixing the rice seedling tray using the seedling tray fixing mechanism, the rice seedling trays are usually fixed one by one, so that when replacing the rice seedling trays, the replaced rice seedling trays need to be disassembled one by one before replacing new rice seedling trays, which makes it inconvenient to disassemble and replace the rice seedling trays, thereby affecting the transplanting efficiency of the rice transplanter.

[0005] To achieve the above object, the present invention provides the following technical solution: comprising a fixing groove, a plug-in slide groove is provided at the front end of the fixing groove, a rice seedling tray is movably connected to the inner wall of the plug-in slide groove, a fixing frame is fixedly installed on the outer periphery of the front end of the fixing groove, an opening and closing door is hingedly installed on the side end of the fixing frame, springs are fixedly installed at the four corners of the middle of the inner side of the opening and closing door, and a baffle is fixedly installed on the top end of the spring side; A roller groove is formed through the bottom end surface of the fixed groove, and a power-assisting roller is rotatably connected to the inner wall of the roller groove through a rotating shaft. A transmission shaft is fixedly installed in the middle of the power-assisting roller, and a first transmission sprocket and a second transmission sprocket are fixedly installed on the outer curved surface of the side end of the transmission shaft from the outside to the inside. A driving motor is fixedly installed on the rear side of the lower end of the fixed groove, and a third transmission sprocket is fixedly installed on the outer curved surface of the transmission shaft part inside the driving motor.

[0006] Preferably, supporting feet for supporting the fixing groove are fixedly installed on both sides of the lower end surface of the fixing groove, and there are several supporting feet, which are symmetrically distributed on both sides of the lower end surface of the fixing groove.

[0007] Preferably, an internal threaded mounting hole is formed through the lower end surface of the supporting foot, so that the supporting foot and the fixing groove are mounted on the upper end of the rice transplanter through the internal threaded mounting hole and the matching bolts.

[0008] Preferably, an electromagnetic door lock for opening and closing the opening and closing door is installed at the opening of the opening and closing door and the fixed frame, and there are four springs, which are symmetrically distributed at the four corners of the middle part of the inner side surface of the opening and closing door.

[0009] Preferably, there are several roller grooves, and every two roller grooves form a group, and several groups of roller grooves are symmetrically distributed from front to back along the bottom end surface of the fixed groove.

[0010] Preferably, the outer curved surface of the upper end of the power-assisting roller is movably connected to the lower end surface of the rice seedling tray, and the side end of the transmission shaft penetrates and is rotatably connected to the lower end side wall of the fixing groove.

[0011] Preferably, the inner transmission shaft portion of the drive motor is rotatably connected to the rear side wall of the lower end of the fixed groove through a rotating shaft, the third transmission sprocket is transmission-connected to the first transmission sprocket through a chain, and the second transmission sprockets are transmission-connected to each other through a chain.

[0012] Compared with the prior art, the present invention has the following beneficial effects: When the opening and closing door is closed, the baffle plate will horizontally block and limit the rice seedling tray. At the same time, when the baffle plate horizontally blocks and limits the rice seedling tray, the elastic potential energy of the spring will always maintain the thrust on the baffle plate, so that the baffle plate always keeps pushing and blocking the rice seedling tray, thereby achieving the effect of batch fixing of the rice seedling trays, avoiding the need to fix the rice seedling trays one by one, resulting in affecting the transplanting efficiency of the rice transplanter; When the driving motor is controlled to be turned on, the driving motor will drive the third transmission sprocket to rotate synchronously. When the third transmission sprocket rotates synchronously, it will drive the first transmission sprocket to rotate synchronously through the chain. When the first transmission sprocket rotates synchronously, it will drive the transmission shaft to rotate synchronously. When the transmission shaft rotates synchronously, it will drive the second transmission sprocket to rotate synchronously through the chain, so that all the transmission shafts are synchronously transmitted. When all the transmission shafts are synchronously transmitted, they will drive the power-assisted roller to rotate synchronously. When the power-assisted roller rotates synchronously, it will assist in driving the rice seedling tray to move back and forth. Therefore, when the rice seedling tray is plugged into the inner wall of the plug-in slide groove, the power-assisted roller can automatically drive the rice seedling tray to move backward or forward along the inner wall of the plug-in slide groove, thereby realizing batch fixing of the rice seedling trays and facilitating batch power-assisted plugging or withdrawal of the rice seedling trays.
