An automated precision seed covering device

Abstract

The present invention belongs to the field of agricultural machinery, and in particular to an automated precision seed covering device. The preparation of planting blocks usually involves mixing seeds, soil, water retaining agents and fertilizers, and placing the mixture in an extrusion device for extrusion molding. However, the amount of seeds put in cannot be precisely controlled manually, especially for seeds with a smaller volume, and the preparation personnel are not good at grasping the timing of seed putting in. In the present invention, seeds are adsorbed by a seed suction tube, and a pushing structure is driven to move by a second conveyor belt, so that the seed suction tube loads and unloads seeds at fixed points. Two gas rods are provided to keep the mounting plate in a horizontal state at all times, so as to prevent the mounting plate from being lateralized when the telescopic end of the hydraulic telescopic rod is extruding the mounting plate, thereby causing the local seed suction tube to be too high, which results in the failure of the seeds to be adsorbed on the seed suction tube.

[0026] (III) Beneficial effects

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. In the present invention, the air inside the suction tube is extracted by an air pump to form a negative pressure inside the suction tube, so that the seeds can be adsorbed. The pushing structure is driven to move by the second conveyor belt. When it moves to the position where the material needs to be unloaded, the air pump stops pumping air and supplies air to the suction tube through the air suction pipe, so that the pressure inside the suction tube becomes larger, and then the seeds adsorbed on the seed suction tube are lowered to complete the fixed-point unloading.

[0029] 2. In the present invention, the rotating shaft on the rotating motor drives the rotating handle to rotate, and the rotating handle drives the rotating gear to move in the inner gear ring through the rotating rod, and at the same time drives the swing rod to reciprocate through the rotating rod. Through the sliding groove arranged on the isolation baffle, the sliding block can pass through the sliding groove to drive the first locking plate to reciprocate, and one side of the first locking plate slides in contact with the isolation baffle, so that the first locking plate can block the sliding groove when moving, preventing the seeds from flowing into the first limiting slide groove and the second limiting slide groove along the sliding groove to damage the swing rod, and the first locking plate drives the second locking plate and the moving plate inserted between the first locking plate and the second locking plate to reciprocate, thereby driving the stirring rod to reciprocate, stirring the seeds, and preventing the seeds from sticking together; the isolation baffle can ensure that the inner gear ring, the rotating gear and the first limiting slide groove are isolated from the seeds while stirring the seeds, thereby protecting the stirring structure and reducing the failure rate.

[0030] 3. In the present invention, two gas rods are provided to keep the mounting plate in a horizontal state at all times, thereby preventing the mounting plate from tilting sideways when the telescopic end of the hydraulic telescopic rod squeezes the mounting plate, causing the local seed suction tube to be too high and resulting in the seeds not being adsorbed on the seed suction tube.

[0031] Fourth, in the present invention, before use, the staff can connect seed suction tubes of different calibers to the docking tube, thereby achieving the adsorption of different types of seeds.

[0032] 5. In the present invention, the meshing strip is semi-cylindrical, which can increase the contact area between the first turntable, the second turntable and the meshing strip on the first conveyor belt, and the contact area between the second meshing groove and the meshing strip on the second conveyor belt, so that the transmission can be performed more stably. After the meshing strip on the second conveyor belt is meshed with the second meshing groove on the lower clamping meshing plate, the second conveyor belt is fixed between the upper clamping plate and the lower clamping meshing plate by bolts and nuts, and then the second conveyor belt is locked and fixed to the pushing structure, so that the second conveyor belt can drive the pushing structure to move more stably.

[0033] 6. In the present invention, the buffer spring can be limited by the upper limit seat and the lower limit seat, and the storage hopper can be supported by the buffer spring. The buffer spring is limited by the provided slide rod to prevent the buffer spring from being over-compressed and popping out from between the upper limit seat and the lower limit seat, causing harm to the staff.

A second rotating disk 7 is fixedly connected to the shaft body of the rotating shaft 5 close to the driving motor 3. The first rotating disk 6 and the second rotating disk 7 are connected by a first transmission belt 8.

[0053] Both ends of the two rotating shafts 5 are fixedly connected with a third rotating disk 9, and the two third rotating disks 9 on the same side of the two rotating shafts 5 are connected by a second transmission belt 10;

[0054] Two guide rails 11 are also fixedly connected to the chassis 1. The two guide rails 11 are respectively located at the two ends of the rotating shaft 5. The two guide rails 11 are slidably connected with the same pushing structure, which is connected to the second conveyor belt 10. A suction structure is provided on the side of the pushing structure away from the driving motor 3, and the suction structure is connected to the air pump 2.

[0055] like Figure 8-Figure 10 As shown, a support structure is provided on the upper surface of the chassis 1, and the support structure is used to support the storage hopper 12 and to increase the height of the storage hopper 12 so that the suction structure can absorb the seeds in the storage hopper 12. The support structure includes a hopper support base 13, a buffer spring 16 and a slide bar 18. The hopper support base 13 is fixedly connected to the upper surface of the chassis 1, and the storage hopper 12 is arranged above the hopper support base 13. The four corners of the outer edge of the storage hopper 12 are fixedly connected with docking plates 14, and the bottoms of multiple docking plates 14 are fixedly connected with upper limit seats 15, and multiple upper limit seats 15 are sleeved with buffer springs 16. The upper surface of the hopper support base 13 is fixedly connected with a lower limit seat 17 corresponding to the upper limit seat 15, and the free end of the buffer spring 16 is sleeved on the lower limit seat 17;

[0056] A slide rod 18 is fixedly connected to the lower limit clamping seat 17, and the free end of the slide rod 18 passes through the upper limit clamping seat 15 and extends above it. The free end of the slide rod 18 is threadedly connected to a locking sleeve 19;

[0057] Specifically, the buffer spring 16 can be limited by the upper limit clamping seat 15 and the lower limit clamping seat 17, and the storage hopper 12 can be supported at a certain height by the buffer spring 16.

[0058] The storage hopper 12 is provided with a stirring structure inside, and the stirring structure is used to stir the seeds in the storage hopper 12 to prevent the seeds from sticking together, and to separate the seeds to prevent the seeds from falling into the stirring structure;

[0059] Specifically, the seeds are poured into the storage hopper 12, and the suction structure absorbs the seeds to complete the feeding. The driving motor 3 drives the first turntable 6 to rotate counterclockwise, and the first turntable 6 drives the second turntable 7 to rotate counterclockwise through the first conveyor belt 8, thereby driving the rotating shaft 5 and the third turntables 9 at both ends thereof to rotate counterclockwise. Under the action of the second conveyor belt 10, the pushing structure and the suction structure are driven to move forward along the direction of the storage hopper 12, thereby driving the suction structure to move forward, and the seeds are discharged at a fixed point.

[0060] After unloading is completed, the driving motor 3 drives the first turntable 6 to rotate clockwise, and the first turntable 6 drives the second turntable 7 to rotate clockwise through the first conveyor belt 8, thereby driving the rotating shaft 5 and the third turntable 9 at both ends of the rotating shaft to rotate clockwise. Under the action of the second conveyor belt 10, the pushing structure moves along the direction of the driving motor 3, so that the pushing structure and the suction structure are reset, waiting for the next cycle, so as to perform fixed-point loading and unloading of seeds.

[0061] Embodiment 2

[0062] like Figure 1-Figure 15 As shown, this embodiment is improved on the basis of the first embodiment as follows: further, a plurality of first meshing grooves 21 are provided on the first rotating disk 6, the second rotating disk 7 and the third rotating disk 9, and a meshing strip 22 is provided on the first conveyor belt 8 and the second conveyor belt 10, and the meshing strip 22 is semi-cylindrical and meshedly connected with the first meshing groove 21;

[0063] The pushing structure includes a sliding base 23, an upper clamping plate 24 and a lower clamping meshing plate 25. The sliding base 23 is provided with two groups and both have dovetail grooves 26 at the bottom. The guide rail 11 is slidably connected in the dovetail grooves 26. The sliding base 23 is fixedly connected with an upper clamping plate 24 at one end close to the second conveyor belt 10. The bottom of the upper clamping plate 24 is in contact with the upper surface of the second conveyor belt 10. The upper surface of the lower clamping meshing plate 25 is provided with a second meshing groove 27. The second meshing groove 27 is meshed with the meshing strip 22. The lower clamping meshing plate 25 is located directly below the upper clamping plate 24 and is fixedly connected by bolts 57 and nuts. The second conveyor belt 10 is clamped between the upper clamping plate 24 and the lower clamping meshing plate 25.

[0064] The meshing strip 22 is semi-cylindrical, which can increase the contact area between the first turntable 6, the second turntable 7 and the meshing strip 22 on the first conveyor belt 8, and the contact area between the second meshing groove 27 and the meshing strip 22 on the second conveyor belt 10, so that transmission can be performed more stably. After the meshing strip 22 on the second conveyor belt 10 is meshed with the second meshing groove 27 on the lower clamping meshing plate 25, the second conveyor belt 10 is fixed between the upper clamping plate 24 and the lower clamping meshing plate 25 by bolts 57 and nuts, and then the second conveyor belt 10 is locked and fixed to the pushing structure, so that the second conveyor belt 10 can more stably drive the pushing structure to move.

[0065] Furthermore, the tops of the two sets of sliding bases 23 are fixedly connected to the same gantry 28, and the tops of the gantry 28 are fixedly connected to support plates 29 on both sides, and the upper surfaces of the two support plates 29 are fixedly connected to the same hydraulic rod support plate 30, and gas rods 38 are arranged on both sides of the hydraulic rod support plate 30, and the telescopic ends of the two sets of gas rods 38 penetrate the hydraulic rod support plate 30 and extend to the bottom thereof, and the ends of the telescopic ends of the two sets of gas rods 38 are fixedly connected to the same mounting plate 32;

[0066] like Figure 6 and Figure 7 As shown, the material suction structure includes a suction pipe 34 and a plurality of suction pipe clamping plates 33. The same side of the plurality of suction pipe clamping plates 33 is fixedly connected to the mounting plate 32. The suction pipe 34 is clamped on the suction pipe clamping plate 33. The suction pipe 34 is hollow inside and the top is connected to the air pump 2 through the suction pipe 35. The bottom of the suction pipe 34 is connected to a docking pipe 36.

[0067] Furthermore, a hydraulic telescopic rod 31 is also provided on the hydraulic rod support plate 30, and the telescopic end of the hydraulic telescopic rod 31 passes through the hydraulic rod support plate 30 and extends to the bottom thereof, and the telescopic end of the hydraulic telescopic rod 31 abuts against the mounting plate 32;

[0068] Further, such as Figure 7 As shown, the docking tube 36 is in an inverted cone shape, and a seed suction tube 37 is clamped on the docking tube 36. The seed suction tube 37 is connected to the inside of the suction tube 34. The seeds can be adsorbed by the set seed suction tube 37. Before use, the staff can clamp the seed suction tubes 37 of different calibers on the docking tube 36, thereby realizing the adsorption of different types of seeds. The docking tube 36 is in an inverted cone shape, so that the seed suction tubes 37 of different calibers can be clamped on the docking tube 36.

[0069] Specifically, when the seeds are adsorbed and loaded, the air pump 2 extracts the air inside the suction tube 34, so that a negative pressure is formed inside the suction tube 34, and the hydraulic telescopic rod 31 extends the telescopic end, squeezes the mounting plate 32 downward to make it move downward, so that the seed suction tube 37 descends into the storage hopper 12 and adsorbs the seeds. When the mounting plate 32 moves downward, the air rod 38 is in a stretched state. When the adsorption is completed, the telescopic end of the hydraulic telescopic rod 31 shrinks and resets, and the air rod 38 also shrinks and resets, thereby driving the mounting plate 32 to reset, so that the seed suction tube 37 is extracted from the storage hopper 12. The two gas rods 38 can keep the mounting plate 32 in a horizontal state at all times, thereby preventing the mounting plate 32 from tilting to the side when the telescopic end of the hydraulic telescopic rod 31 squeezes the mounting plate 32, causing the local seed suction tube 37 to be too high and resulting in the seeds not being adsorbed on the seed suction tube 37. When the seed suction tube 37 moves to the position where seeds need to be planted, the drive motor 3 stops rotating, and the air pump 2 stops pumping air, and supplies air to the suction tube 34 through the suction pipe 35, so that the pressure inside the suction tube 34 increases, thereby lowering the seeds adsorbed on the seed suction tube 37 to complete the seeding.

The air pump 2 extracts the air inside the suction tube 34 to form a negative pressure inside the suction tube 34. The hydraulic telescopic rod 31 extends the telescopic end and squeezes the mounting plate 32 downward to move it downward, so that the seed suction tube 37 descends into the storage hopper 12 and absorbs the seeds. When the mounting plate 32 moves downward, the gas rod 38 is in a stretched state. When the absorption is completed, the telescopic end of the hydraulic telescopic rod 31 shrinks and resets, and the gas rod 38 also shrinks and resets, thereby driving the mounting plate 32 to reset, so that the seed suction tube 37 is drawn out of the storage hopper 12.

[0080] After the meshing strip 22 on the second conveyor belt 10 is meshed with the second meshing groove 27 on the lower clamping meshing plate 25, the second conveyor belt 10 is fixed between the upper clamping plate 24 and the lower clamping meshing plate 25 by means of bolts 57 and nuts, the driving motor 3 drives the first turntable 6 to rotate counterclockwise, the first turntable 6 drives the second turntable 7 to rotate counterclockwise through the first conveyor belt 8, and then drives the rotating shaft 5 and the third turntable 9 at both ends thereof to rotate counterclockwise, the second conveyor belt 10 drives the upper clamping plate 24 and the lower clamping meshing plate 25 to move, and then drives the pushing structure and the suction structure to move forward along the direction of the storage hopper 12, when the suction pipe 34 moves to the position where the material needs to be discharged, the driving motor 3 stops rotating, and at the same time the air pump 2 stops pumping, and supplies air to the suction pipe 34 through the suction pipe 35, so that the pressure inside the suction pipe 34 increases, and then the seeds adsorbed on the seed suction pipe 37 are lowered to complete the discharge;

[0081] After unloading is completed, the driving motor 3 drives the first turntable 6 to rotate clockwise, and the first turntable 6 drives the second turntable 7 to rotate clockwise through the first conveyor belt 8, thereby driving the rotating shaft 5 and the third turntable 9 at both ends of the rotating shaft to rotate clockwise. Under the action of the second conveyor belt 10, the pushing structure moves along the direction of the driving motor 3, so that the pushing structure and the seed suction tube 37 are reset, waiting for the next cycle.

[0082] However, as is well known to those skilled in the art, the working principles and wiring methods of the air pump 2, drive motor 3, hydraulic telescopic rod 31, gas rod 38, rotary motor 39 and motor 56 are commonplace, and are all conventional means or common knowledge, and will not be elaborated here.
