Description

Technical Field

[0001] The utility model relates to the technical field of seedling tray racks, in particular to a seedling tray rack for agricultural machinery. Background Art

[0002] A rice transplanter is an agricultural machine used to plant rice seedlings in rice fields. When planting, the seedlings are first taken out of the seedling tray with mechanical claws and then planted in the soil.

[0003] The current seedling tray rack has the following problems: (1) The mechanical claw and the seedling tray rack are separate and need to be installed separately during installation. After installation, they need to be adjusted several times so that the mechanical claw can accurately grasp the seedlings on the seedling tray rack, which makes installation inconvenient; (2) The seedlings are placed on the seedling tray rack, and the seedling tray rack is fixed. The mechanical claw needs to grasp all the seedlings on the seedling tray rack before placing new seedlings on the seedling tray rack. It is impossible to grasp the seedlings in the front row and then transport the new seedlings to the front row, resulting in low grasping efficiency; (3) One mechanical claw is configured for each seedling, and one mechanical claw is configured for one power device, which increases the number of power devices and increases the cost. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides a seedling tray rack for agricultural machinery to solve the problems mentioned in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A seedling tray rack for agricultural machinery includes a belt conveyor, which includes brackets on both sides, a transmission shaft rotatably connected between the two brackets, a conveyor belt transmission-connected to the two transmission shafts, and a drive motor transmission-connected to one of the transmission shafts. The characteristics are as follows: a plurality of seedling pots arranged in a matrix are installed on the conveyor belt, support columns are installed on the brackets on both sides, a top plate extending forward is connected to the support column, the bottom surface of the top plate is connected to a slide through a linear displacement mechanism, and the slide can be driven to the front side of the belt conveyor by the linear displacement mechanism, a hydraulic cylinder is installed on the bottom surface of the slide, the lower end of the hydraulic cylinder is connected to a mounting plate, and a seedling clamping mechanism for clamping seedlings out of a row of seedling pots is installed on the mounting plate.

[0007] Preferably, the linear displacement mechanism includes two first bearing seats connected to the bottom surface of the top plate, a screw rod rotatably connected to the two first bearing seats, a guide rod connected to the two first bearing seats, a first motor installed on the outside of the top plate and transmission connected to the screw rod, a slide seat threadedly connected to the screw rod, and a slide seat slidingly connected to the guide rod.

[0008] The above technical solution starts the first motor to drive the screw to rotate, which can drive the slide to move forward along the guide rod, thereby sending the captured seedlings to the front of the belt conveyor.

[0009] Preferably, the seedling clamping mechanism includes a plurality of clamping units and a driving mechanism for driving the plurality of clamping units to work simultaneously.

[0010] Preferably, the clamping unit includes a first clamping rod connected to the mounting plate by a screw, a second clamping rod rotatably connected to the first clamping rod by a rotating shaft, and the first clamping rod and the second clamping rod are arranged opposite to each other; the driving mechanism includes a second bearing seat connected to both ends of the mounting plate, a transmission rod rotatably connected to the two second bearing seats, a second motor installed on the mounting plate, a first bevel gear connected to the rotating shaft, and a plurality of second bevel gears connected to the transmission rod and meshing with the first bevel gear.

[0011] The above technical solution starts the second motor to drive the transmission rod to rotate, and the transmission rod drives the first bevel gear to rotate through the second bevel gear, thereby driving the rotating shaft to rotate, and the rotating shaft drives the second clamping rod to rotate, and through the cooperation of the first clamping rod and the second clamping rod, the seedlings are grabbed.

[0012] Preferably, a first position sensor is provided on the bottom surface of the mounting plate, and a second position sensor cooperating with the first position sensor is provided on the belt conveyor near each row of seedling pots.

[0013] The above technical solution is that every time the belt conveyor moves forward a certain distance, the second position sensor cooperates with the first position sensor. When any row of seedling pots reaches the appropriate position, the belt conveyor stops working so that the seedlings are located on the front side below the seedling clamping mechanism, which is convenient for the seedling clamping mechanism to grab the seedlings.

[0014] Preferably, the bracket is connected to an outwardly extending connecting plate, and a plurality of screw holes are formed on the connecting plate.

[0015] According to the above technical solution, the belt conveyor can be installed on planting equipment, such as a seedling transplanter, through the connecting plate and the screw holes thereon.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The seedling clamping mechanism is installed on the belt conveyor. During installation, you only need to install the belt conveyor on the seedling transplanter, which improves the convenience of installation. A seedling is placed in each seedling pot. The seedling clamping mechanism grabs the seedlings in the seedling pots in the front row and then plants them in the soil of the field. The seedling clamping mechanism then returns to its original position. The belt conveyor then continues to transport the seedlings forward for a distance until the seedling pots in the next row reach the bottom of the seedling clamping mechanism. The next round of grabbing and planting is then carried out. This method can achieve orderly grabbing and planting of seedlings, thereby improving planting efficiency.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] See also Figure 1-4 A seedling tray rack for agricultural machinery includes a belt conveyor. The belt conveyor comprises two brackets 1, a transmission shaft rotatably connected between the two brackets, a conveyor belt 2 transmission-connected to the two transmission shafts, and a drive motor transmission-connected to one of the transmission shafts. The drive motor drives the transmission shaft to rotate, thereby driving the conveyor belt to rotate. The belt conveyor is prior art and will not be described in detail in this embodiment.

[0026] The conveyor belt 2 is provided with a plurality of seedling pots 3 arranged in a matrix, and support columns 4 are provided on the brackets on both sides. The support columns 4 are connected to a top plate 5 extending forward. The bottom surface of the top plate 5 is connected to a slide 6 through a linear displacement mechanism. The slide 6 can be driven to the front side of the belt conveyor by the linear displacement mechanism. Specifically, the linear displacement mechanism includes two first bearing seats 9 connected to the bottom surface of the top plate, a screw rod 10 rotatably connected to the two first bearing seats, a guide rod 11 connected to the two first bearing seats, a first motor 12 installed on the outside of the top plate and connected to the screw rod, the slide 6 is threadedly connected to the screw rod 10, and the slide 6 is slidably connected to the guide rod 11. When the first motor 12 is started and the screw rod 10 is driven to rotate, the slide 6 can be driven to move forward along the guide rod 11, thereby sending the captured seedlings to the front of the belt conveyor for planting the seedlings.

[0027] A hydraulic cylinder 7 is mounted on the bottom surface of the slide 6. To improve stability, two hydraulic cylinders may be used. A mounting plate 8 is connected to the lower end of the hydraulic cylinder 7. A seedling clamping mechanism is mounted on the mounting plate 8 to clamp seedlings from any row of seedling pots 3. The seedling clamping mechanism includes a plurality of clamping units and a driving mechanism that drives the plurality of clamping units to operate simultaneously.

[0028] Specifically, the clamping unit includes a first clamping rod 13 connected to the mounting plate by screws, and a second clamping rod 14 rotatably connected to the first clamping rod via a rotating shaft 21. The first clamping rod 13 and the second clamping rod 14 are arranged opposite each other. The driving mechanism includes a second bearing seat 15 connected to both ends of the mounting plate, a transmission rod 16 rotatably connected to the two second bearing seats, a second motor 17 mounted on the mounting plate, a first bevel gear 18 connected to the rotating shaft, and a plurality of second bevel gears 19 connected to the transmission rod that mesh with the first bevel gears. When the second motor 17 is started, the transmission rod 16 is driven to rotate. The transmission rod 16 drives the first bevel gear 18 to rotate through the second bevel gear 19, thereby driving the rotating shaft 21. The rotating shaft 21 drives the second clamping rod 14 to rotate. Through the cooperation of the first clamping rod 13 and the second clamping rod 14, the seedlings are grasped. Moreover, all the clamping units can be driven to work by only one second motor 17, which reduces the installation of the driving device and reduces the cost.

[0029] A first position sensor is provided on the bottom surface of the mounting plate 8, and a second position sensor is provided on the belt conveyor near each row of seedling pots 3, which cooperates with the first position sensor. Each time the belt conveyor moves forward a certain distance, the second position sensor cooperates with the first position sensor. When any row of seedling pots reaches the appropriate position, the belt conveyor stops, so that the seedlings are positioned in front of and below the seedling clamping mechanism, thereby facilitating the seedling clamping mechanism to grasp the seedlings.

[0030] The working principle of this embodiment is as follows: a seedling is placed in each seedling pot, and the seedling is conveyed forward by the belt conveyor. Through the cooperation of the second position sensor and the first position sensor, each time a certain distance is conveyed, that is, when any row of seedling pots reaches the front side below the lifting plate, the hydraulic cylinder extends, driving the mounting plate to descend, so that the seedling is located between the second clamping rod and the first clamping rod, and then the second motor 17 is started to drive the transmission rod 16 to rotate, and the transmission rod 16 drives the first bevel gear 18 to rotate through the second bevel gear 19, thereby driving the rotating shaft 21 to rotate, and the rotating shaft 21 drives the second clamping rod The rod 14 rotates, and the seedlings are grabbed through the cooperation of the first clamping rod 13 and the second clamping rod 14. Then the slide 6 is driven to move away from the belt conveyor through the linear displacement mechanism, and then the hydraulic cylinder is controlled to continue to extend, so that the seedlings are inserted into the soil. Then the hydraulic cylinder contracts, and the linear displacement mechanism drives the slide back to its original position. Then the belt conveyor continues to transport it forward for a distance until the last row of seedling pots reaches the front side under the mounting plate, and a round of grabbing and planting seedlings is carried out. According to this method, the orderly grabbing and planting of seedlings can be achieved, thereby improving the planting efficiency.
