Description

Technical Field

[0001] The present invention relates to the technical field of seed drills, and more particularly to a fully automatic drum-type tray seed drill. Background Art

[0002] The drum tray seeder is a precision seeding equipment used for tray seedling cultivation in agriculture. Its core is to absorb seeds through negative pressure suction holes when the drum rotates, and then release negative pressure above the tray to complete the seeding.

[0003] The invention also provides an air suction type hole seeder with publication number CN113767731A, which includes a sowing device, the sowing device including a hole pressing mechanism and a seed spreading mechanism, the hole pressing mechanism being arranged in front of the seed spreading mechanism; the seed spreading mechanism including a seed guide assembly, a seed spreading assembly and a seed collecting assembly, the seed spreading assembly including a coaxially arranged seed spreading drum and an air chamber disk, the seed spreading drum being evenly provided with a plurality of axially penetrating seed spreading chambers along the circumference, each seed spreading chamber being provided with an exhaust hole along its length direction, the end surface of the air chamber disk being sequentially provided with a negative pressure air chamber, a positive pressure air chamber and a normal pressure air chamber along the circumference, one end of the seed spreading chamber being connected with the negative pressure air chamber, the positive pressure air chamber and the normal pressure air chamber in sequence during one rotation cycle of the seed spreading drum, and the other end corresponding to the seed spreading chamber being closed by an end cover; the seed guide assembly is arranged near the starting end of the negative pressure air chamber, and the seed collecting assembly is arranged below the seed guide assembly and near the positive pressure air chamber. The invention can effectively solve the problems of suction hole clogging and unstable negative pressure during sowing.

[0004] The above-mentioned device uses a single negative pressure to absorb the seeds. The seeds are adsorbed on the outer wall of the drum under the action of negative pressure, and then switched to a pressure-free state at the lower vertical point of the drum. The seeds are scraped off the outer wall of the drum under the action of a scraper. In actual use, seeds with small diameters will be stuck in the holes of the drum. When in a pressure-free state, the seeds cannot slide down under the action of gravity, nor can they be shoveled off by the scraper, which causes the drum to be blocked, resulting in vacancies for subsequent seed planting. At the same time, an air-blowing nozzle arranged obliquely above the drum sprays gas to blow off excess seeds on the outer wall of the drum. In actual use, when there is a gap between the seeds and the drum, the negative pressure cannot firmly adsorb the seeds. When the air blows off the excess seeds, the unstable seeds will also be blown off. The seeds will be scattered on the upper part of the device, which is not conducive to the recycling of seeds, resulting in insufficient planting effects and waste of seeds. At the same time, the existing structure is relatively complex, resulting in high manufacturing and maintenance costs of the equipment. For this reason, we propose a fully automatic drum-type tray seeder. Summary of the Invention

[0035] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0036] Embodiment 1

[0037] Referring to Figure 1-9 The embodiment of the present application discloses a full-automatic drum type plug seeding machine, which comprises a rack 1 and a conveying belt 2 installed on the rack 1. Above the conveying belt 2, along the conveying direction, there are, in sequence, a first soil covering device 3 for covering soil to the plug, a plug pressing device 4 for pressing a seeding plug hole on the plug, a seeding drum device 5 for seeding to the seeding plug hole, a second soil covering device 6 for covering soil to the plug again, and a spraying device 7 for spraying water to the plug.

[0038] In the embodiment, the first soil covering device 3 and the second soil covering device 6 are the same in structure, and each comprises a feeding machine 31, a containing groove 32 and a soil covering belt 33.

[0039] The feeding machine 31 has a feeding port, a soil conveying part and a discharging port.

[0040] The containing groove 32 is installed on the rack 1 and is in communication with the discharging port of the feeding machine 31. The containing groove 32 has a soil discharging port.

[0041] The soil covering belt 33 is installed at the soil discharging port of the containing groove 32, and the soil covering belt 33 is connected with a driving part.

[0042] The soil conveying part can adopt a conveying belt cooperating with a soil shoveling plate. The soil is placed on the conveying belt. After the soil is shovelled by the soil shoveling plate, the soil is conveyed from the feeding port to the discharging port of the feeding machine 31 in cooperation with the conveying belt, and then enters the containing groove 32. Other soil conveying part devices that can convey soil into the containing groove 32 can also be selected, which are not limited herein. This is a conventional technology, and will not be described herein. The first soil covering device 3 and the second soil covering device 6 can also not comprise the feeding machine 31, and soil can be directly added into the containing groove 32.

[0043] The soil material is added to the feed port of the upper feeder 31. Under the action of the soil conveying member, the soil material reaches the discharge port of the feeder 31, enters the receiving trough 32, and falls on the covering belt 33. The covering belt 33 rotates under the drive of the driving member to lay the soil material on the hole tray; the receiving trough 32 provides a storage structure for the soil. The covering belt 33 can drive the soil to leave the receiving trough 32 and fall into the inside of the hole tray when rotating. The outer wall of the covering belt 33 is provided with triangular protrusions. The protruding triangular structure increases the volume of the carried soil. The space between the triangular structures can carry a fixed amount of soil. By controlling the rotation speed of the covering belt 33, different covering amounts can be achieved. The triangular protrusion setting increases the friction on the soil and increases the stability of the carried soil. Each triangle can carry soil quantitatively. The driving member can be a driving roller or other structure that can realize the rotation of the covering belt 33. This is an existing conventional structure and will not be repeated here.

[0044] In this embodiment, the cavitation pressing device 4 includes two fixing frames 41 arranged on the upper part of the conveyor belt 2, and a cavitation pressing roller 42 is installed between the two fixing frames 41 through bolts.

[0045] The fixed frame 41 can fix the cavitation roller 42. The protrusions on the surface of the cavitation roller 42 can squeeze through the hole plate there, and press the soil out of the seed planting pits while squeezing. The protrusions on the surface of the cavitation roller 42 correspond to the pits of the hole plate, and a row of protrusions corresponds to a row of pits, pressing the soil in the hole plate out of the seed planting pits. By setting the cavitation roller 42 as it rotates, the area of ​​the pit pressing structure is reduced while also increasing the continuity of the pit pressing, thereby improving work efficiency. The two sides of the two fixed frames 41 can be connected to lifting components, such as existing conventional structures such as a screw rod and a rotary handle structure, which will not be repeated here. The fixed frame 41 is connected to the screw rod, and the rotary handle is rotated to realize the lifting and lowering of the fixed frame 41 and the cavitation roller 42, so as to better cooperate with the hole plate and press out seed planting pits of different depths.

[0046] In this embodiment, the sowing roller device 5 includes a lifting plate 51, a fixed shaft 52, two fixed rings 53 and a roller 54. The fixed shaft 52 is arranged in the middle of the lifting plate 51, and the two fixed rings 53 are rotatably installed on the middle and front ends of the fixed shaft 52 respectively. The roller 54 is fixedly installed between the two fixed rings 53. The lower part of the fixed shaft 52 is provided with a positive pressure piece 55 for blowing out seeds, and the front end of the fixed shaft 52 is provided with a collecting piece 56 for collecting seeds.

[0047] The lifting plate 51 and the fixed shaft 52 are the overall skeleton of the device, which are used to provide structural support for the entire device. The fixed shaft 52 can provide rotation support for the fixed ring 53 and the roller 54. The two fixed rings 53 are fixedly installed at the front and rear ends of the roller 54, which can provide support for the rotation of the roller 54. The surface of the roller 54 is covered with rows of holes. The number of holes in each row corresponds to the number of holes in each row of the hole tray. The holes can absorb seeds.

[0048] The positive pressure piece 55 includes a mounting block 551 arranged at the lower part of the fixed shaft 52, and a sealing ring 553 arranged at the inner wall of the lower sealing plate 552.

[0049] The lower part of the fixed shaft 52 is provided with two positive pressure pieces 55 for blowing out seeds, and the mounting block 551 is fixedly arranged at the lower part of the fixed shaft 52, and can be combined with the sealing plate 552 to form an adsorption cavity, and the sealing ring 553 is arranged at the inner wall of the lower sealing plate 552, and can increase the sealing property between the sealing plate 552 and the roller 54.

[0050] The collecting piece 56 includes a mounting bracket 561 arranged at the front end of the fixed shaft 52, and a collecting groove one 562 movably mounted at the left side of the mounting bracket 561 and abutting against the left side of the roller 54, and a material groove 563 arranged at the right side of the lifting plate 51 and abutting against the right side of the roller 54, and a collecting groove two 564 arranged at the lower part of the mounting bracket 561 and abutting against the lower part of the roller 54.

[0051] The mounting bracket 561 is used to provide mounting support for the collecting groove one 562 and the collecting groove two 564, the material groove 563 is arranged at the right side of the lifting plate 51, the roller 54 rotates counterclockwise during operation, and when the seeds adsorbed on the single hole of the roller 54 are too much, the seeds will be thrown into the collecting groove one 562 under the action of the centrifugal force of the roller 54, thereby collecting the seeds and preventing the seeds from being wasted or excessively transported to the lower part of the roller 54, the collecting groove two 564 is horizontally arranged and is tangent to the lower part of the roller 54 at the left side, thereby assisting in shoveling the seeds from the surface of the roller 54 into the hole pit of the plug, the positive pressure piece 55 at the right side can blow the seeds on the outer surface of the roller 54 into the collecting groove two 564, the collecting groove two 564 can collect the seeds, and the plane at the right side of the collecting groove two 564 is used to hold the seeds falling between the material groove 563 and the roller 54, and the material groove 563 is used to provide temporary storage of the seeds and is a storage component for feeding the device.

[0052] The left side of the material groove 563 is matched with the roller 54, the inner wall of the material groove 563 is arranged to be inclined, the lower edge of the collecting groove one 562 is bent upward, the left side of the collecting groove two 564 is tangent to the lower part of the roller 54, the rear side of the lifting plate 51 is provided with a lifting piece 57 for driving the lifting plate 51 to lift, and the rear side of the lifting plate 51 is provided with a driving assembly 58 for driving the fixed ring 53 to rotate.

[0053] The left side of the trough 563 matches the curvature of the roller 54, which can prevent the seeds from falling out of the gap between the two to the greatest extent. The inclined surface of the inner wall of the trough 563 can make the seeds slide down naturally to the contact surface of the trough 563 and the roller 54 under the action of gravity. The bending of the lower edge of the collecting trough 562 can prevent the seeds stored in the collecting trough 562 from being vibrated and sliding out when the machine is working, and at the same time can fit more closely to the surface of the roller 54.

[0054] The lifting member 57 includes two limit blocks 573 slidably connected to the rear side of the lifting plate 51. A fixed plate 511 is provided on the rear side of the limit blocks 573. The upper portion of the fixed plate 511 is rotatably connected to a second screw rod 572. The upper end of the second screw rod 572 is provided with a rotary handle 571. The lower end of the second screw rod 572 is threadedly connected to the upper portion of the lifting plate 51.

[0055] The rotation of the handle 571 drives the second screw 572 to rotate, and the second screw 572 can push the lifting plate 51 to move, thereby adjusting the height of the lifting plate 51 in real time and stably adjusting the working height of the roller 54. The limit block 573 can stabilize the position of the lifting plate 51 and prevent the lifting plate 51 from shaking back and forth in front of the fixed plate 511.

[0056] The driving assembly 58 includes a second motor 584 arranged on the rear side of the lifting plate 51, a second synchronous wheel 582 is provided at the driving end of the second motor 584, a first synchronous wheel 581 is provided on the rear side of the rear fixed ring 53, and a synchronous belt 583 is provided on the outer periphery of the first synchronous wheel 581 and the second synchronous wheel 582.

[0057] A second protective shell 59 covering the outside of the driving assembly 58 is provided on both the front and rear sides of the lifting plate 51. The second protective shell 59 is used to protect the driving assembly 58.

[0058] Protective shell 2 59 covers the outside of driving assembly 58 and can isolate danger. Motor 2 584 starts to drive synchronous wheel 2 582 to rotate. Through the transmission of synchronous belt 583, synchronous wheel 1 581 and fixed ring 53 can be driven to rotate, thereby driving roller 54 to rotate. The toothed structure on the inner side of synchronous belt 583 can provide stable power transmission.

[0059] The rear side of the mounting frame 561 and the lower part of the collecting tank 562 are both provided with two rollers that slide on the outer wall of the drum 54;

[0060] The setting of the roller can support the rear part of the mounting frame 561, and can also make certain adjustments to the collecting tank 562, so that the collecting tank 562 can automatically fit on the outer wall of the drum 54 under the action of gravity. The roller can prevent the collecting tank 562 from directly scraping the outer wall of the drum 54, thereby avoiding wear of the drum 54.

[0061] The sealing ring 553 is in a closed ring shape and surrounds the inner wall of the closing plate 552 . The closing plate 552 is in a closed ring shape and surrounds the lower portion of the mounting block 551 . The sealing ring 553 abuts against the inner wall of the roller 54 .

[0062] The annular arrangement of the sealing plate 552 and the sealing ring 553 is for providing a good closed environment and isolating the negative pressure environment inside the drum 54 .

[0063] The chamber between the mounting block 551 and the closing plate 552 is connected to positive pressure, and air can be blown into the interior of the chamber. The interior of the roller 54 is connected to negative pressure, and air can be sucked in through the holes on the surface of the roller 54 to adsorb seeds. The roller 54 is driven by the driving component 58 to rotate counterclockwise. When the roller 54 rotates, the seeds are adsorbed on the holes on the surface of the roller 54 by the internal negative pressure air. When the roller 54 rotates, the excess seeds that are not firmly adhered to the surface of the roller 54 will fall into the inside of the collecting tank 562 under the action of centrifugation. The roller 54 continues to rotate, and when the seeds are brought to the lower part of the roller 54, the positive pressure piece 55 at the bottom blows out positive pressure air, and the positive pressure air blows the sealing ring 553 to move and fit against the inner wall of the roller 54. The roller 54 rotates to this position, thereby isolating the negative pressure inside the roller 54. The closing plate 552 has a through hole in the middle, from which positive-pressure air can be blown out. When the roller 54 rotates to this position, the negative-pressure adsorption force disappears, and the seeds fall into the holes of the hole tray under their own action and the blowing of the positive-pressure air. Even if there are seeds that are stuck firmly, the lower end of the collecting groove 2 564 that fits the roller 54 can push the seeds away from the holes and drop them into the holes of the hole tray. The roller 54 continues to rotate, and when it moves to another positive-pressure member 55, the positive-pressure member 55 at this location corresponds to the collecting groove 2 564, and the positive-pressure air blows the firmly stuck seeds or impurities into the inside of the collecting groove 2 564, thereby cleaning the holes and collecting the seeds to avoid waste.

[0064] In this embodiment, the spraying device 7 includes multiple rows of spraying pipes arranged along the conveying direction of the conveyor belt 2, and multiple spraying heads are provided on the spraying pipes.

[0065] The spray pipe is connected to the water tank, and a water pump is provided between the spray pipe and the water tank. The water in the water tank is transported to the spray pipe through the water pump and sprayed out through the spray head to water the seeds in the hole tray.
