Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, and more specifically, to a seedling tray collecting and arranging device. Background Art

[0002] With the development of agricultural production mechanization in China, automated production lines are now mostly used for rice seedling raising to improve the quality of seedlings. First, it goes through an automated seedling raising production line to complete soil covering, sowing, and soil covering in the seedling tray. Then it is placed in a dark room for centralized heat and moisture preservation to emerge. After the emergence is neat in the dark room, it is then manually transported to a hardening shed or paddy field for secondary seedling raising. Traditional seedling tray transportation mostly uses manual handling methods. For example, the seedling trays are transported from the cultivation room to the paddy field by a transport cart, and then manually carried from the edge of the ridge to the inside of the paddy field for hydroponic growth. Such a handling mode has a high labor intensity, requires the operator to walk back and forth between the ridge and the paddy field, not only has low work efficiency, but also has high operating costs. At the same time, the seedlings are easily damaged during manual handling, affecting the growth of the seedlings.

[0003] After retrieval, Chinese patent document CN116472825A discloses a field seedling tray collecting and arranging device and method, including a vehicle frame. One track is respectively arranged on both sides of the vehicle frame. The track is driven by load-bearing wheels and towing wheels, and the track and the towing wheels are respectively rotatably arranged on the track. A support frame is arranged on one side of the vehicle frame. The support frame is located between the two tracks. A chain belt is arranged on the support frame. A plurality of conveying plates are detachably installed on the chain belt. According to the number and area of the seedling trays to be arranged or retrieved as needed, a collecting and arranging plan is planned, a reasonable route is specified, and the seedling trays are quickly retrieved or arranged. However, the device in this application does not have a loading device, and the seedling trays still need to be manually loaded onto the device after being transported to the device. Moreover, the device performs one-way arranging and collecting of the seedling trays and needs to turn when working in the field, and cannot conveniently arrange the seedling trays.

[0019] 3. Beneficial effects

[0020] Adopting the technical solution provided by the present utility model, compared with the existing well-known technologies, it has the following remarkable effects:

[0021] (1) For a seedling tray collecting and arranging device of the present utility model, two upper and lower tray mechanisms are symmetrically arranged along the tray separating mechanism, and the lifting or lowering of the upper and lower tray mechanisms on both sides is controlled by a suspension mechanism. When the arrangement of a row of seedling trays is completed, the upper and lower tray mechanism on one side is lifted, and the upper and lower tray mechanism on the other side is lowered. Without moving the empty collecting and arranging tray device to the initial position, the arrangement of the next row of seedling trays can be immediately carried out. While the upper and lower tray mechanisms are moving, the seedling trays are arranged, improving the efficiency of seedling tray arrangement.

[0022] (2) For a seedling tray collecting and arranging device of the present utility model, a guiding tray is provided to guide the seedling trays to the tray separating mechanism. The guiding tray is detachably connected to the tray separating mechanism and can be disassembled and reassembled according to the moving direction of the collecting and arranging tray assembly, so that the seedling trays transported from different directions can be guided to the tray separating mechanism; during tray collection, the conveying direction of the seedling trays can also be adjusted, which is convenient for adjustment.

[0023] (3) For a seedling tray collecting and arranging device of the present utility model, a tray pushing mechanism is provided on the tray separating mechanism. Compared with the traditional flipping type tray separation, the tray pushing mechanism of the present utility model drives the pushing member to rotate forward or backward by a motor, so that the seedling trays can be pushed onto the upper and lower tray mechanisms on both sides; since the seedling trays are pushed, the dropping of the soil in the seedling trays caused by the sudden stop of the flipping type tray separation is avoided.

[0024] (4) For a seedling tray collecting and arranging device of the present utility model, a transition plate is provided at the end of the upper and lower tray mechanisms. When arranging the trays, the transition plate enables the seedling trays to fall smoothly to the ground. The end of the transition plate is set in a style parallel to the ground. When collecting the trays, the seedling trays can be lifted, so that the seedling trays can smoothly enter the driving belt part. At the same time, the end of the transition plate is parallel to the ground, and when the collecting and arranging tray assembly moves, the transition plate will not insert into the soil, avoiding damage to the land.

[0039] Embodiment

[0040] Combined Figure 1 And Figure 2, a seedling tray collecting and arranging device in this embodiment includes a tray separating mechanism 33 and an upper and lower tray mechanism 34. One upper and lower tray mechanism 34 is arranged on each side of the tray separating mechanism 33. The upper and lower tray mechanisms 34 are symmetrically arranged along the tray separating mechanism 33. One end of the upper and lower tray mechanism 34 is movably connected to the tray separating mechanism 33, and the other end is arranged close to the ground; the upper and lower tray mechanism 34 rotates around the connection with the tray separating mechanism 33 as the axis. In this embodiment, in order to enable the seedling tray 1 to smoothly transition to the tray separating mechanism 33, a transition machine 31 and a guiding tray 32 are arranged between the seedling tray 1 conveying mechanism and the tray separating mechanism 33 to convey the seedling tray 1 to the tray separating mechanism 33. The arrangement of the transition machine 31 and the guiding tray 32 enables the seedling tray 1 to smoothly transition along the belt and roller structures on the transition machine 31 and the guiding tray 32, so that the seedling tray 1 can stably move between the seedling tray 1 conveying mechanism and the tray separating mechanism 33, and avoid the soil and seedlings in the seedling tray 1 from falling due to the shaking of the seedling tray 1. In this embodiment, the guiding tray 32 is an arc-shaped structure, one end is detachably connected to the tray separating mechanism 33, and the other end is connected to the transition machine 31. The other end of the transition machine 31 is connected to the seedling tray 1 conveying mechanism. In this embodiment, the guiding tray 32 and the tray separating mechanism 33 are arranged on the same horizontal plane, while the transition machine 31 is inclined. Since the guiding tray 32 and the tray separating mechanism 33 are higher than the seedling tray 1 conveying mechanism, in order to enable the seedling tray to be smoothly conveyed to the tray separating mechanism 33, a roller belt transmission structure is arranged on the transition machine 31 of this embodiment to provide power for the seedling tray 1. The guiding tray 32 in this embodiment is arranged to change the conveying direction of the seedling tray 1, changing the longitudinal movement of the seedling tray 1 to lateral movement. The guiding tray 32 in this embodiment is detachably connected to the tray separating mechanism 33, and the direction of the guiding tray 32 can be conveniently adjusted according to the incoming direction of the seedling tray 1. When the seedling tray 1 is conveyed from Figure 1 from left to right in Figure 1 , the guiding tray 32 faces Figure 1 the left side in Figure 1On the right side in it. This ensures that the guiding plate 32 always faces the direction in which the seedling tray 1 is conveyed, ensuring that the seedling tray 1 can be conveyed smoothly. In this embodiment, a connecting plate is provided at the free end of the transfer machine 31 for connecting with the conveying mechanism of the seedling tray 1. A plurality of rollers are provided on the connecting plate to assist the movement of the seedling tray 1 and ensure that the seedling tray 1 can move smoothly. The connecting plate of this embodiment extends downward and extends into the conveying mechanism of the seedling tray 1, and the lower edge of the connecting plate extends beyond the bottom of the seedling tray 1. Taking the belt conveyor of the seedling tray 1 conveying mechanism as an example, the two belts of the belt conveyor support the seedling tray 1, and there is a gap between the two belts. The connecting plate extends into the gap. When the seedling tray 1 is conveyed to the position of the connecting plate, the connecting plate lifts the seedling tray 1, and the rollers provided thereon assist the movement of the seedling tray 1, so that the seedling tray 1 contacts the roller belt transmission structure provided on the transfer machine 31 and conveys the seedling tray 1 onto the guiding plate 32. This embodiment provides a guiding plate 32 to guide the seedling tray 1 to the disk dividing mechanism 33. The guiding plate 32 is detachably connected to the disk dividing mechanism 33 and can be disassembled and reassembled according to the moving direction, so that the seedling trays 1 transported from different directions can be guided onto the disk dividing mechanism 33; during the closing of the tray, the conveying direction of the seedling tray 1 can also be adjusted, which is convenient for adjustment.

[0041] Combined Figure 3, in this embodiment, a pushing plate mechanism is arranged on the tray separating mechanism 33 to push the seedling tray 1 conveyed by the guiding tray 32 towards the upper and lower tray mechanism 34, and then the upper and lower tray mechanism 34 conveys the seedling tray 1 to the ground along the inclined slope. The tray separating mechanism 33 of this embodiment includes a guiding mounting frame 331 for supporting the guiding tray 32, connecting the guiding tray 32 to the tray separating mechanism 33, and moving along with the tray separating mechanism 33. It also includes a suspension mounting frame 332, and a suspension mechanism 338 is arranged on the suspension mounting frame 332. A steel wire rope is wound on the suspension mechanism 338, and the other end is connected to one end of the upper and lower tray mechanism 34 and the ground. By winding or releasing the steel wire rope, the suspension mechanism 338 can adjust the distance between the upper and lower tray mechanism 34 and the ground. Since in this embodiment, the upper and lower tray mechanisms 34 are arranged on both sides of the tray separating mechanism 33, and only one side of the upper and lower tray mechanisms 34 needs to work during tray placing and collection, therefore, the suspension mechanism 338 of this embodiment can also wind the steel wire rope to retract one side of the upper and lower tray mechanism 34 and lower the upper and lower tray mechanism 34 on the other side. In this embodiment, two suspension mechanisms 338 can be set to be respectively connected to one upper and lower tray mechanism 34, or only one upper and lower tray mechanism 34 can be set to be connected to two upper and lower tray mechanisms 34 at the same time. Only the steel wire ropes of the two upper and lower tray mechanisms 34 need to be wound staggeredly during installation (that is, connect the steel wire ropes when one is raised and the other is lowered). When the suspension mechanism 338 retracts one side of the upper and lower tray mechanism 34 by rotation, the upper and lower tray mechanism 34 on the other side is lowered accordingly. When the suspension mechanism 338 rotates in reverse, similarly, one side of the upper and lower tray mechanism 34 is retracted and the upper and lower tray mechanism 34 on the other side is lowered. In this embodiment, the suspension mechanism 338 is a rope winding machine, and the rope winding machine is driven to rotate by a motor gear. The suspension mechanism 338 of this embodiment can be directly connected to the motor for driving, or can be connected to the motor for driving after passing through a speed reducer. In order to ensure the driving power of the motor and for convenient connection, in this embodiment, the motor is arranged on the side of the suspension mechanism 338, and a mounting plate 337 is arranged on the suspension mounting frame 332, and the motor is fixed on the mounting plate 337.

[0042] In this embodiment, the tray separation mechanism 33 further includes a driving section, which is connected to the guiding tray 32 and conveys the seedling trays 1 conveyed by the guiding tray 32 to the other end of the tray separation mechanism 33, so that a plurality of seedling trays 1 are arranged on the tray separation mechanism 33. In this embodiment, a blocking structure can be provided on the driving section to separate a plurality of seedling trays 1 according to the required spacing between the seedling trays 1; alternatively, the blocking structure can be not provided so that all the seedling trays 1 are closely arranged. In this embodiment, the driving section is divided into a first driving section 333 and a second driving section 334. First, the first driving section 333 conveys the seedling tray 1 from the guiding tray 32 to the driving section, and then the second driving section 334 conveys the seedling tray 1 to the other end. In this embodiment, a tray pushing mechanism is provided above the driving section. The tray pushing mechanism of this embodiment includes a pushing member 335 and a driving mechanism 336 for driving the pushing member 335 to move. In this embodiment, the pushing member 335 is a long rod extending along the length direction of the tray separation mechanism 33, and the length of the long rod is equal to the length of the tray separation mechanism 33, so as to be able to push all the seedling trays 1 on the tray separation mechanism 33 down. The pushing member 335 is arranged on the upper part of the tray separation mechanism 33 and is located on the side of the tray separation mechanism 33 where the upper and lower tray mechanism 34 is installed. The distance between the long rod and the driving section is less than the height of the seedling tray 1. In this embodiment, the driving mechanism 336 is a gear-chain structure. In this embodiment, two gears are provided, on which chains are arranged, and two pushing members 335 are arranged at intervals on the chains. The distance between the two pushing members 335 is the width of the tray separation mechanism 33. In this embodiment, the motor drives the chain to rotate through the gears, so that the two pushing members 335 move to push the seedling trays 1 on the tray separation mechanism 33 towards the upper and lower tray mechanism 34. The motor of this embodiment can rotate forward and backward to push the seedling trays 1 towards the upper and lower tray mechanisms 34 on both sides. The tray pushing mechanism is provided on the tray separation mechanism 33 of this embodiment. Compared with the traditional flip-type tray separation, the tray pushing mechanism of this embodiment drives the pushing member to rotate forward or backward by the motor, so as to be able to push the seedling trays 1 onto the upper and lower tray mechanisms 34 on both sides; since the seedling trays 1 are pushed, the falling of the soil in the seedling trays 1 caused by the sudden stop of the flip-type tray separation is avoided.

[0043] At the lower part of the tray dividing mechanism 33 of this embodiment, traveling wheels 21 are further provided, and are mounted on the tray dividing mechanism 33 through a traveling mounting frame 22. A plurality of traveling wheels 21 are provided below both lateral sides of the tray dividing mechanism 33 for assisting the tray dividing mechanism 33 to move. In this embodiment, in order to be able to use the seedling tray collecting and arranging device to cover the seedling trays in the field, a method of arranging longitudinally first and then moving laterally is selected, that is, the field is divided into a plurality of longitudinal rows arranged horizontally. The traveling wheels 21 first drive the collecting and arranging device to walk from one end of the field to the other end along the longitudinal direction in the field to cover a longitudinal row of seedling trays 1. Then move laterally a certain distance (this distance is adjusted as needed. If the seedling trays 1 need to be closely arranged, then move and closely adhere to the seedling trays 1 in the previous longitudinal row after moving. If they do not need to be closely arranged, then move the length of the required interval), and move in the reverse direction to cover the seedling trays 1 in the next longitudinal row. Repeat the above process until the entire field is completely covered. In this embodiment, the traveling wheels 21 can have various structures, and a universal wheel structure can be selected, or an orbital wheel structure can also be used. When the traveling wheels 21 are selected as universal wheels, the direction of the universal wheels needs to be fixed longitudinally first, and when a longitudinal row is covered, then the direction of the universal wheels is changed to lateral. When the traveling wheels 21 are selected as orbital wheels, tracks are laid longitudinally in the field. After the traveling wheels 21 move longitudinally along the tracks, the collecting and arranging device is then translated to the next longitudinal row; at this time, the longitudinal tracks can be set to be movable to drive the collecting and arranging device to move and translate, or can also be set to be immovable, and while arranging the seedling trays 1 in a longitudinal row, lay the tracks for the next longitudinal row. In this embodiment, two upper and lower tray mechanisms 34 are symmetrically arranged along the tray dividing mechanism 33, and the lifting or lowering of the upper and lower tray mechanisms 34 on both sides is controlled by a suspension mechanism 338. When a row of seedling trays 1 is arranged, the upper and lower tray mechanism 34 on one side is lifted, and the upper and lower tray mechanism 34 on the other side is lowered. Without moving the empty collecting and arranging device to the initial position, the arrangement of the next row of seedling trays 1 can be immediately carried out. While the upper and lower tray mechanisms 34 are moving, the seedling trays 1 are arranged, improving the arrangement efficiency of the seedling trays 1.

[0044] Combined with Figure 4, the upper and lower tray mechanism 34 in this embodiment includes a frame 341. The frame 341 is a square frame, composed of side plates on both sides and multiple cross beams connecting the two side plates. In this embodiment, the multiple cross beams are arranged at intervals. Specifically, in this implementation, a cross beam is provided at each of the two ends and the middle of the two side plates. Among them, the cross beams at both ends are not directly arranged at the ends of the side plates, but are spaced a certain distance from the ends and are arranged close to the ends. In this embodiment, multiple conveyor belts 343 are provided on the frame 341. The conveyor belts 343 can be chains, belts, or other devices capable of forming a conveying structure. In this embodiment, a driving roller and a driven roller are respectively arranged at both ends of the frame 341, and are driven to rotate by a driving shaft 342, so as to drive the conveyor belts 343 installed on the driving roller and the driven roller to move, and drive the seedling tray 1 to move on the upper and lower tray mechanism 34. In this embodiment, multiple narrow conveyor belts 343 are provided, and the multiple conveyor belts 343 are arranged at intervals, so that when the soil on the seedling tray 1 spills out, it can directly fall to the ground through the gaps and will not cause excessive weight on the conveyor belts 343. In order to prevent the conveyor belts 343 from being too long and unable to be tensioned, in this embodiment, while a tensioning mechanism is provided, a supporting structure is also provided on each cross beam to support the conveyor belts 343. In this embodiment, baffles 344 are provided on the side plates on both sides, and the baffles 344 can prevent the seedling tray 1 from falling. In this embodiment, multiple transition plates 345 are provided at the lower end (i.e., the end in contact with the ground) of the upper and lower tray mechanism 34. The ends of the transition plates 345 are parallel to the ground and can be pressed by the soil on the ground, so as to ensure that the ends of the transition plates 345 will not be inserted into the soil. In this embodiment, transition plates 345 are provided at the ends of the upper and lower tray mechanism 34. When arranging the trays, the transition plates 345 enable the seedling tray 1 to fall smoothly to the ground. The ends of the transition plates 345 are set in a style parallel to the ground. When collecting the trays, the transition plates 345 can lift the seedling tray 1, so that the seedling tray 1 can smoothly enter the driving belt part. At the same time, the ends of the transition plates 345 are parallel to the ground. When a seedling tray collecting and arranging device moves, the transition plates 345 will not be inserted into the soil, avoiding damage to the land. In this embodiment, an induction device is further provided at the lower part of the upper and lower tray mechanism 34 close to the ground. When the seedling tray reaches the position of the induction device, devices such as an infrared sensor or a pressure plate sensor are used to receive signals, and the collecting and arranging assembly 3 is driven to move to arrange the seedling trays properly.

[0045] The above schematically describes the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present invention, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
