TECHNICAL FIELD
[0001] The present application relates to the technical field of facility agricultural machinery, in particular to a plant seedling planting groove planting and covering device. BACKGROUND
[0002] In recent years, the demand for research and development of intelligent agricultural equipment has been increasing year by year, and the production efficiency of facility agriculture is improved by improving the automation level of equipment. So far, the most common form of facility greenhouse soil culture planting is to use multi-layer vertical planting racks combined with planting grooves, which is low in cost and easy to use. However, in the field of agricultural automation research, although various types of agricultural equipment for field planting, such as seeders, transplanters, harvesters, etc., have made great progress and a large number of special agricultural equipment for different crops have emerged, the research and development of automated equipment for facility greenhouse environment, especially for planting grooves as the direct object of operation, is still relatively lagging behind. This situation seriously hinders the realization of full-process automation production of facility greenhouse soil culture planting.
[0003] Through research and study on a large number of transplanting devices, the present application selects the planting and covering mechanism of the transplanting device as the core research object and designs a planting and covering device suitable for the planting mode of facility greenhouse plant seedling planting grooves. SUMMARY
[0004] The technical problem to be solved by the present application is to overcome the shortcomings of the prior art and provide a planting and covering device with small geometric size, high reliability and suitable for the planting mode of facility greenhouse plant seedling planting grooves.
[0005] To solve the above technical problems, the present application adopts the following technical solutions:
[0006] In a first aspect, a plant seedling planting groove planting and covering device is provided, characterized in that the device comprises a lifting module, a seedling planting module and a covering module.
[0007] The lifting module comprises a lead screw module, a planting and covering mechanism mounting plate, a servo motor, a synchronous belt and a synchronous wheel, etc. The seedling planting module comprises a duckbill planter, multiple sets of duckbill opening and closing long rods, an opening and closing long rod mounting plate, a planting mechanism L mounting plate, a mounting plate, a duckbill mounting plate fixing block, a telescopic cylinder, a linear guide rail mounting block, a linear guide rail, a duckbill opening and closing pull rod, a duckbill opening and closing special-shaped connecting block, a duckbill planter mounting frame and a single-sided duckbill planter, etc. The covering module comprises a covering plate opening and closing mechanism, a covering plate, a telescopic cylinder, a light shaft, an upper mounting plate, a vertical mounting plate, a linear bearing, a light shaft seat mounting block, a lower mounting plate, a covering plate mounting block, a connecting rod, a linear guide rail, a middle mounting plate, a light shaft seat, a cylinder mounting block, etc.
[0008] Furthermore, the seedling planting module consists of five duckbill planters that can operate simultaneously. The opening and closing of a single duckbill planter is controlled by a pull rod and a special-shaped connecting block, and is fixed to the duckbill planter mounting frame by stepped bolts, thereby realizing the opening and closing rotational movement. Then, the mounting frame is fixed to the mounting plate by screws, which facilitates the synchronous control of multiple planters. The pull rod is then fixed to the opening and closing long rod by stepped bolts. The latter is connected to the cylinder through the opening and closing long rod connecting block, and synchronously completes the up and down extension and retraction movements, thereby realizing the opening and closing movements of multiple duckbill planters. At the same time, the two ends of the opening and closing long rod are fixed to the slider of the linear guide rail, which constrains its up and down linear movement.
[0009] Furthermore, the planting and soil covering module consists of two sets of soil covering plate opening and closing mechanisms and soil covering plates. The soil covering plates and linear guide rails are connected by mounting blocks, thereby constraining the soil covering plates to achieve linear opening and closing movements. The linear guide rails are fixed to the lower mounting plate by screws, the vertical mounting plate is fixed to the lower mounting plate by screws, and the upper mounting plate is fixed to the vertical mounting plate by screws. The telescopic cylinder is connected to the upper mounting plate by a cylinder mounting block and fixed by screws. The middle mounting plate is connected to the telescopic cylinder by screws to achieve up and down movement. The optical axis seat is fixed to the optical axis by screws on the upper mounting plate and the vertical mounting plate. The linear bearing is installed on the middle mounting plate and has a clearance fit with the optical axis. The connecting rod is hinged by stepped screws to connect the middle mounting plate and the soil covering plate mounting block, and achieves up and down movement synchronously with the telescopic cylinder. Since the two connecting rods are of the same length, when the telescopic cylinder moves, the connecting rod drives the soil covering plates on both sides to achieve opening and closing movements.
[0010] Furthermore, the connection methods between the tie rod and the opening / closing rod, as well as the connecting rod and the middle mounting plate and the soil covering plate mounting block, are not limited to hinges, bearing connections, etc.
[0011] Secondly, a method for planting and covering soil using a plant seedling planting trough and soil covering device is provided, characterized by comprising the following steps:
[0012] S1: Before the device is operated, the telescopic cylinder is in the retracted state, and at the same time, the opening and closing rod drives the opening and closing lever to make the duckbill planter in the closed state. At this time, seedlings are put into the planter, and the planting trough filled with soil substrate is in place.
[0013] S2: The soil covering module starts to operate, the telescopic cylinder extends, driving the middle mounting plate to move downwards, and the connecting rod hinged to it drives the soil covering plate mounting block to move linearly on the linear guide rail. The soil covering plate fastened to it moves synchronously, completing the opening action.
[0014] S3: The lifting module starts running. The servo motor drives the synchronous wheel, and the synchronous belt drives the screw module to rotate in the forward direction. The planting and covering device moves downward as a whole. The closed duckbill planter and the open covering plate move downward at the same time until the preset soil depth is reached and the hole-piercing action is completed.
[0015] S4: The seedling planting module begins to move, the telescopic cylinder extends, and the opening and closing rod mounting plate fixed to it moves synchronously, driving the opening and closing rod to move upward. The opening and closing pull rod hinged to it moves upward synchronously, further driving the opening and closing irregular connecting piece fixed to the single-sided duckbill planter to move upward, thereby opening the duckbill planter and letting the seedling fall into the hole made in the previous step.
[0016] S5: The lifting module starts to move, the servo motor drives the synchronous wheel, the synchronous belt drives the screw module to rotate in the opposite direction, the planting and covering device moves upward as a whole, the opened duckbill planter and the opened covering plate move upward at the same time until the preset soil depth is reached and the planting action is completed.
[0017] S6: The soil covering module starts to operate. The telescopic cylinder retracts, causing the middle mounting plate to move upward. The connecting rod hinged to it causes the soil covering plate mounting block to move linearly on the linear guide rail. The soil covering plate, which is fastened to it, moves synchronously to complete the closing action. At the same time, this action is used to realize the soil covering function.
[0018] S7: The lifting module starts to move. The servo motor drives the synchronous wheel, and the synchronous belt drives the screw module to rotate in the opposite direction. The planting and covering device moves upward as a whole. The open duckbill planter and the closed covering plate move upward at the same time until they stop at the initial working position.
[0019] S8: The seedling planting module begins to move, the telescopic cylinder retracts, and the opening and closing rod mounting plate fixed to it moves synchronously, driving the opening and closing rod to move downward. The opening and closing pull rod hinged to it moves downward synchronously, further driving the opening and closing irregular connecting piece fixed to the single-sided duckbill planter to move downward, thereby closing the duckbill planter. At this point, the entire device's operation is complete.
[0020] The advantages of this invention include:
[0021] The planting and soil-covering device of this invention is simple and reliable in operation, completing both planting and soil-covering actions in a single lifting motion. It features a compact, aesthetically pleasing, robust, and highly reliable structure. Furthermore, all components are composed of standard parts and simple machined parts, facilitating manufacturing. The modular design also aids in assembly and maintenance. In addition, the seedling planting and soil-covering method employed in this invention exhibits clear and predictable movement patterns, further enhancing the reliability of the device's operation.

Then, the mounting frame is fixed to the mounting plate 205 by screws, which facilitates the synchronous control of multiple planters. The pull rod 210 is then fixed to the opening and closing long rod 202 by the stepped bolt. The latter is connected to the cylinder through the opening and closing long rod connecting block 203, and synchronously completes the up and down extension and retraction movements, thereby realizing the opening and closing movements of multiple duckbill planters.
