Seeding machine for agricultural seedling planting

Abstract

The invention relates to the technical field of agriculture, in particular to a seeding machine for agricultural seedling planting. Comprising a bottom plate, symmetrically-distributed electric wheels are installed on the side wall of the bottom plate, an installation frame is fixedly connected to the top of the bottom plate, a conveying assembly used for transferring seedlings is arranged on the installation frame, and symmetrically-distributed installation frames are fixedly connected to the top of the bottom plate. Water is supplemented to the seedlings through the water supply assembly, and the water supplementing range is larger than the range of the pits, so that the situation that the seedlings topple and follow-up growth is affected due to the fact that water sources are directly irrigated to the seedlings can be avoided, and meanwhile the situation that seedling roots find the water sources nearby to grow upwards, and consequently the lodging resistance of the seedlings is low is prevented. Water is replenished by inserting into the lower side of the seedling root system, so that the seedling root system can extend downwards to find a water source, and the lodging resistance of the seedling is enhanced.

Description

Technical Field

[0001] The invention relates to the technical field of agriculture, and in particular to a seeder used for planting agricultural seedlings. Background Art

[0002] Agricultural seedling planting is a key link in the crop planting process. Its technical points and management measures directly affect the growth, development and yield of crops. At the same time, agricultural seedling planting needs to comprehensively consider variety characteristics, environmental conditions and cultivation techniques, and cultivate strong seedlings through meticulous management, laying the foundation for high and stable crop yields.

[0003] In the process of planting seedlings, the existing seedling planting machines mostly integrate planting and watering. In the process of watering, the existing seedling planting machines mostly plant the seedlings first and then water them. In the watering process, the seedlings are mostly watered directly. This watering method can easily cause the seedlings to topple over, thereby affecting the subsequent growth of the seedlings. At the same time, watering on the ground can easily cause the roots of the seedlings to need nearby water sources to grow upward, resulting in reduced resistance to lodging of the seedlings, poor survival of the seedlings, and the need for subsequent seedling replacement, which increases the workload.

A chute matching with the strip-shaped protrusion is opened on the inner side surface of the limiting sliding ring 24, which is convenient for guiding the containing pipe 25 and can prevent the containing pipe 25 from rotating by itself, thus affecting the planting of seedlings.

[0021] The side wall of the holding tube 25 is fixedly connected with a hollow frame 26. The bottom of the holding tube 25 is equipped with two semi-conical toggle buckets 27 through a torsion spring rod.

[0022] A vertical plate 29 is fixedly connected to the bottom plate 1, and the vertical plate 29 is located between the mounting frame 23 and the mounting frame 3. A groove 30 is provided on the vertical plate 29. The left side wall of the vertical plate 29 is fixedly connected to a trapezoidal plate 32 located inside the groove 30 through an arc rod 31. The lower end of the trapezoidal plate 32 is fixedly connected to a flexible rod 321. A track groove is formed between the trapezoidal plate 32 and the vertical plate 29, and the fixing rod 28 is slidably located in the track groove. The front and rear side walls of the hollow frame 26 are fixedly connected to fixing frames 33, and a hollow ring 34 is fixedly connected between the two fixing frames 33, and the hollow ring 34 is located on the inner side of the mounting frame 3. The diameter of the hollow ring 34 is larger than the diameter of the containing tube 25, so as to facilitate watering the seedlings after planting. The bottom of the hollow ring 34 is connected to four hollow plug rods 35 distributed equidistantly in the circumferential direction, and the bottom end of the hollow plug rod 35 is provided with a drainage hole. A drainage hole, a circular groove is provided on the top of the base plate 1, and a hollow plug rod 35 is located in the circular groove. The length of the hollow plug rod 35 is greater than the length of the semi-conical toggle bucket 27, which is convenient for delivering water to the lower side of the seedling planting site. The bottom end of the hollow plug rod 35 is located on the lower side of the bottom end of the semi-conical toggle bucket 27. A water delivery component is provided on one side of the base plate 1, and the water delivery component includes a water tank 36 fixedly connected to the top of the base plate 1, the water tank 36 is located on the left side of the installation frame 3, the top of the water tank 36 is connected to a water inlet pipe 37, and the right side wall of the water tank 36 is connected to a water delivery pipe 38, the water delivery pipe 38 passes through the left side wall of the installation frame 3 and is connected to the hollow ring 34, and the water delivery pipe 38 after passing through the left side wall of the installation frame 3 is a telescopic pipe, and a pump body is installed at the bottom of the water tank 36, and the water outlet end of the pump body is connected to the water delivery pipe 38.

[0023] During use, the operator moves the bottom plate 1 to a suitable position through the electric wheels 2. The operator moves the bottom plate 1 through the electric wheels 2. At the same time, the operator puts the seedlings into the annular plate 8 on the left. The seedlings falling into the annular plate 8 then fall downward between the two semi-conical storage hoppers 9 thereon. At the same time, the operator starts the reduction motor 5 to work. The operation of the reduction motor 5 can make the rotating shaft 4 rotate. The rotation of the rotating shaft 4 can drive the mounting disc 6 to rotate. The rotation of the mounting disc 6 can make the annular plate 8 move circumferentially through the mounting block 7. The rotation of the annular plate 8 can make the semi-conical storage hoppers 9 thereon move circumferentially. Therefore, during the process that the semi-conical storage hopper 9 containing seedlings moves circumferentially to the directly above the storage pipe 25, the rotation of the mounting disc 6 can make the pressing plate 11 thereon move circumferentially. The circumferential movement of the pressing plate 11 pushes the rotating rod 16 downward. The downward movement of the rotating rod 16 makes the pressing block 17 move downward through the moving frame 14, and the return spring 15 is compressed accordingly. The downward movement of the pressing block 17 pushes the two connecting rods 10 away from each other. The two connecting rods 10 moving away from each other cause the semi-conical storage hoppers 9 connected to them to swing away and open, and the torsion spring rods on the semi-conical storage hoppers 9 are tightened and store energy accordingly. The seedlings between the two semi-conical storage hoppers 9 then fall downward into the storage pipe 25.

[0024] When the mounting plate 6 rotates to make the extrusion plate 11 thereon move away from the rotating rod 16, the movable frame 14 drives the extrusion block 17 to move upward and reset under the action of the reset spring 15, and the rotating shaft 4 rotates to drive the shaft 19 to rotate through the meshing of the first bevel gear 18 and the second bevel gear 20, and the rotation of the shaft 19 will drive the disc 21 to rotate, and the rotation of the disc 21 can push the hollow frame 26 to move downward through the pin 22 thereon, and the downward movement of the hollow frame 26 will drive the containing tube 25 to move downward, and the downward movement of the containing tube 25 can drive the two semi-conical toggling buckets 27 thereon to move downward, and the semi-conical toggling buckets 27 can be driven to move downward. The movable bucket 27 moves downward and slides in the track groove through the fixed rod 28 thereon. When the fixed rod 28 slides downward to the inclined groove of the track groove, the semi-conical movable bucket 27 is now completely inserted into the soil. At this time, the holding tube 25 continues to move downward. At this time, the semi-conical movable bucket 27 slides downward along the inclined groove of the track groove through the fixed rod 28 and moves outward at the same time. Because the connection part of the fixed rod 28 and the semi-conical movable bucket 27 can be deformed, the two semi-conical movable buckets 27 can be moved in opposite directions to open and move the soil outward to complete the hole drilling work. At the same time, the two semi-conical movable buckets The seedlings between 27 then fall into the pit, and when the disc 21 rotates to move the hollow frame 26 upward through the pin rod 22 on it, the fixed rod 28 will pass through the flexible rod 321 during the process of entering the outer vertical groove of the track groove, and the fixed rod 28 will push the flexible rod 321 to deform. After the flexible rod 321 passes over the flexible rod 321, the flexible rod 321 returns to its initial state, and at this time the fixed rod 28 enters the intersection of the inclined groove of the track groove and the outer vertical groove, and the flexible rod 321 can block the fixed rod 28 to prevent the fixed rod 28 from being on the plate cone toggle bucket Under the action of the torsion spring rod, it moves into the inclined groove of the track groove again, and then the containing tube 25 continues to move upward. At this time, it slides upward along the outer vertical groove of the track groove through the fixed rod 28. At this time, the two semi-conical tossing buckets 27 can be moved out of the pit. At this time, the soil squeezed during the outward swing of the semi-conical tossing bucket 27 will flow into the pit, covering the roots of the seedlings and completing the planting of the seedlings. When the fixed rod 28 moves to the upper horizontal groove of the track groove, it moves and resets under the action of the torsion spring rod of the semi-conical tossing bucket 27, so that the two semi-conical tossing buckets 27 can be reset.

[0025] In the above process, when the hollow frame 26 moves downward through the fixed frame 33, the hollow ring 34 can be moved downward. The downward movement of the hollow ring 34 will cause the hollow insertion rod 35 to be inserted into the soil. At this time, the pump body in the water storage tank 36 works to extract water source, and the water source is sent into the hollow ring 34 through the water delivery pipe 38. The water source in the hollow ring 34 is discharged through the drainage holes of the hollow insertion rod 35. Therefore, the watering work for the planted seedlings can be realized. And the depth of the hollow insertion rod 35 inserted downward into the soil should be lower than the depth of the root systems of the seedlings planted. Therefore, it can avoid directly watering the seedlings and causing them to fall over, affecting subsequent growth, and at the same time prevent the root systems of the seedlings from seeking water source upward nearby, resulting in lower lodging resistance of the seedlings. Through the above method, the root systems of the seedlings can extend downward to seek water source, thereby strengthening the lodging resistance of the seedlings.

[0026] In the above process, the planting distance between the seedlings can be adjusted according to the moving distance of the electric wheel 2. Specifically, the electric wheel 2 can be rotated by a corresponding number of turns and then stop working, and after an interval of 1 - 5 seconds, the electric wheel 2 is restarted to work. And the interval time of the pump body in the water storage tank 36 is the same as the interval time of the electric wheel 2.

[0027] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural or equivalent process transformations made by using the content of the specification of the present invention, or directly or indirectly applied in other related technical fields, are equally included in the patent protection scope of the present invention.
