Automatic rice seedling taking and feeding transplanter

[0026] Example 1

[0027] reference figure 1 , 2 3. The automatic bowl seedling transplanting machine of the present invention is operated by a tractor. The whole automatic bowl seedling transplanting machine includes a seedling tray frame 1, a seedling tray conveying mechanism 6, an automatic bowl seedling feeding mechanism 2, Seedling receiving device 5. Seedling guide cup 16. The workers standing on the rear pedal 14 take out the seedling tray from the seedling tray 1 and place it on the seedling tray conveying mechanism 6. The seedling tray conveying mechanism 6 pushes the seedling tray to the seedling removal position of the automatic feeding and feeding bowl seedling mechanism 2. , The automatic pot-feeding mechanism 2 takes out multiple pot seedlings from the seedling tray at a time and feeds them into the seedling receiver 5. The pot seedlings fall from the seedling receiver 5 into the corresponding seedling guide cup 16 under the action of their own weight. A seedling guide cup 16 is fixed around the flexible chain of the seedling guide cup (such as figure 2 As shown, one pair on the left and right sides), the seedling guide cup 16 is provided with a valve at the lower end, the valve is opened by the door opening wedge 19, the pot seedling falls into the transplanting unit 11 corresponding to the transplanter 12 due to its own weight, and the transplanter 12 rotates At the lowest point, the actions of forming holes and planting pot seedlings are completed, and then the soil covering mechanism (not shown in the figure) covers the soil on both sides of the planted pot seedlings, and all the work of transplanting pot seedlings is completed. It should be noted that the transplanting monomer 11 and the transplanter 12 belong to the prior art, and the present invention will not repeat them.

[0028] It also includes the right pedal 13 and the left pedal 15, which are used for assisting the staff to stand up, and are mainly responsible for observing the working conditions of the seedling extractor and making up for leaks in time.

[0029] Example 2

[0030] reference Figure 4 , Figure 5 with Figure 7 , Figure 7 It is a schematic diagram of the structure of the seedling receiver 5, 7-1 is a top view, and 7-2 is a side view. The seedling receiver 5 includes a seedling receiver compartment box 30, a seedling receiver moving back and forth bottom plate 31, and a seedling receiver moving left and right bottom plate 32 , Eccentric wheel track 33.

[0031] The seedling receiver compartment box 30 is fixedly connected to the back and forth moving bottom plate 31 of the seedling receiver. The through hole A at the bottom of the seedling receiver compartment box 30 passes through the seedling receiver to move the bottom plate 31 back and forth, and the seedling receiver moves the bottom plate left and right. 32 is provided with a set of through holes B corresponding to the through holes A at the bottom of the seedling receiver compartment box 30 (such as Figure 7 Among them, there are eight seedling receiving device compartment boxes 30 corresponding to eight through holes), the seedling receiving device compartment box 30 and the seedling receiving device moving back and forth bottom plate 31 form a whole, and the whole body is relative to the seedling receiving device moving left and right bottom plate 32 back and forth By moving, the through hole A and the through hole B can be aligned, and the pot seedlings in the seedling receiving device compartment box 30 can fall into the corresponding seedling guide cup 16.

[0032] The reversing gear set 20 drives a sprocket (not shown in the figure) through a chain, and pushes the eccentric track 33 through the eccentric wheel 21 fixed on the sprocket, and then drives the back and forth movement of the bottom plate 31 to complete the forward and backward movement of the seedling receiver 5 .

[0033] reference Figure 4 , Figure 5 , The walking wheel 9 drives the main shaft 17 through a chain drive, and the main shaft 17 drives a bevel gear set 18 through a chain drive. The bevel gear set 18 drives the main drive sprocket 23 and the seedling guide cup flexible chain, and then drives the seedling guide cup 16 to level Rotate.

[0034] reference Figure 7 After the seedling catcher 5 runs directly above the seedling guide cup 16, the tongue 22 connected to the flexible chain of the seedling guide cup (corresponding to the aforementioned eight seedling catcher compartment boxes 30, each of the eight seedling guide cups 16 A ratchet 22 is provided to drive the seedling receiver to move the bottom plate 32 left and right. The whole body formed by the seedling receiver compartment box 30 and the seedling receiver moving back and forth bottom plate 31 and the seedling receiver moving left and right bottom plate 32 move left and right (in Figure 7-1 In this way, there is no relative displacement in the left and right direction, but relative displacement in the front and rear), and it runs a distance synchronously with the seedling guide cup 16, which can give the pot seedlings in the seedling receiver compartment 30 enough time to fall.

[0035] After the pot seedlings fall into the corresponding seedling guide cups 16 at the same time from the seedling receiving device 5, the ratchet 22 rotates into a horizontal position under the action of the inclined block (not shown in the figure) on the flexible chain fixing frame of the seedling guide cup. At this time, the seedling receiver 5 can be separated from the tongue 22, and then a tension spring (not shown in the figure) will pull the seedling receiver 5 back to its original position; at this moment, each seedling guide cup 16 continues to be driven by the flexible chain of the seedling guide cup The lower end of each seedling guide cup 16 is provided with a valve at the lower end. As the seedling guide cup 16 moves horizontally, the lower end of the valve is opened by the adjustable door wedge 19 from below (by adjusting the position of the door opening wedge 19) Change the opening time of the valve and the length of opening the door), the pot seedlings fall into the corresponding transplanter 12 on the transplanting monomer 11 in turn, and the transplanter 12 equipped with the pot seedling rotates with the transplanting monomer 11 to the lowest point, complete The action of cavitation and planting of pot seedlings (the rotation of the transplanting monomer 11 is realized by the walking wheel 9 through the chain drive to drive the main shaft 17 and the main shaft 17 through the chain drive to achieve), the soil covering mechanism (not shown in the figure) then covers the soil To both sides of the planted pot seedlings, all the work of transplanting pot seedlings has been completed.

[0036] Example 3

[0037] reference Picture 8 As shown, it is a schematic structural diagram (side view) of the seedling tray conveying mechanism 6, including a tray shifting handle 230, a speed increasing gear set 24, and a flexible chain 25. promote( Picture 8 The middle is to push upwards) The plate shifting handle 230 can drive the speed increasing gear set 24, and the speed increasing gear set 24 drives the flexible chain 25 to rotate, and the seedling plate placed on the flexible chain 25 is pushed forward to the seedling removal position.

[0038] A plate-shifting handle limiter 26 is also provided, and the plate-shifting handle limiter 26 is used to control the stroke of the plate-shifting handle 230 when it returns.

[0039] For example, a worker standing on the rear pedal 14 takes out the seedling tray from the seedling tray 1 and places it on the flexible chain 25 of the seedling tray conveying mechanism 6. The movement of the tray handle 230 can be controlled by a pneumatic cylinder or manpower to drive the speed increasing gear. In group 24, the speed is increased by the gears of the speed increasing gear group 24, and the power is transmitted to the flexible chain 25, which relies on the flexible chain 25 to push the seedling tray to the seedling removal position of the automatic pot-feeding mechanism 2.

[0040] For another example, a ratchet (not shown in the figure) is fixed on the shifting handle 230, and the ratchet turns the ratchet 27 to drive the coaxial gears to increase the speed through the gears of the speed-increasing gear set 24 to transmit power to the flexible chain 25 , Relying on the flexible chain 25 to push the seedling tray to the seedling taking position of the automatic feeding and feeding bowl seedling mechanism 2.

[0041] After the pot seedlings in the seedling tray are emptied, they enter the empty seedling tray bracket 4 for storage under the push of the rear seedling tray.
