Abstract
Description
Technical Field
[0001] This utility model belongs to the field of transplanter technology, and in particular relates to a crop planting and seedling transplanter. Background Technology
[0002] A transplanter is a commonly used agricultural machine used in crop cultivation to transplant cultivated crop seedlings into farmland. Before transplanting, the farmland needs to be ridged and mulched. However, the spacing between ridges varies depending on the crop, or the ridge spacing may be uneven during ridging, resulting in the crop not being properly positioned on the ridge during transplanting. Currently, transplanters have fixed transplanting spacing, and adjusting the row spacing requires loosening the planting device and seedling feeder and repeatedly tapping them, which can easily damage the equipment. Summary of the Invention
[0003] The purpose of this invention is to provide a crop planting, seedling raising and transplanting machine to solve the problems existing in the prior art.
[0004] The technical solution adopted by this utility model to solve its technical problem is:
[0005] A crop seedling transplanting machine includes a frame, on which a row spacing adjustment mechanism, wheels, a seedling feeding mechanism, and a planting mechanism are installed. The wheel axles are connected to rotating shafts mounted on the frame via a sprocket mechanism. The rotating shafts are connected to the planting mechanism and the seedling feeding mechanism via sprocket mechanisms. The row spacing adjustment mechanism includes a spacing adjustment slide rail and a load-bearing slide rail mounted on the frame. Several spacing adjustment sliders and several load-bearing sliders are slidably connected to the spacing adjustment slide rail and the load-bearing slide rail, respectively. A connecting box is fixed to the bottom of the spacing adjustment slider. Two half-threaded connecting blocks are slidably connected inside the connecting box. Several spacing adjustment sliders are connected to a spacing adjustment screw mounted on the frame via the half-threaded connecting blocks.
[0006] Furthermore, the frame is equipped with a seat, seedling tray, and hanging rack, while the planting mechanism is equipped with a soil-covering wheel.
[0007] Furthermore, the seedling feeding mechanism includes a seedling feeding shaft and several seedling feeders. The seedling feeding shaft is rotatably mounted on the frame, and the drive end of the seedling feeder is sleeved on the seedling feeding shaft.
[0008] Furthermore, the planting mechanism includes a planting shaft and a planting device. The number of planting devices is the same as the number of seedling feeders. The planting shaft is rotatably mounted on the frame. The drive end of the planting device is sleeved on the planting shaft. The seedling inlet end of the planting device is located at the seedling outlet end of the corresponding seedling feeder.
[0009] Furthermore, both the planting shaft and the seedling feeding shaft are hexagonal shafts, and the rotating shafts are connected to the planting shaft of the planting mechanism and the seedling feeding shaft of the seedling feeding mechanism respectively through a sprocket mechanism.
[0010] Furthermore, both the adjustable slider and the load-bearing slider are self-locking sliders. The number of adjustable sliders and load-bearing sliders is the same as the number of seedling feeders. The seedling feeders are fixed on the corresponding load-bearing sliders. The load-bearing sliders are connected to the corresponding adjustable sliders via connecting rods. A positioning rod is fixed to the bottom of the load-bearing slider. A flange is fixed to one end of the positioning rod. One end of the positioning rod flange is sleeved on the planting shaft and located on one side of the corresponding planter.
[0011] Furthermore, the connecting box is divided into two halves, and each half of the connecting box contains a half-threaded connecting block. The side of the half-threaded connecting block that contacts the adjusting screw is semi-circular and has a thread that matches the adjusting screw. A T-slot is opened on the half-threaded connecting block, and an adjusting screw is inserted into the T-slot. The adjusting screw is threaded through the corresponding half-threaded connecting block, and an adjusting nut is threaded on the outside of the half-threaded connecting block.
[0012] Furthermore, one end of the adjusting screw has a circular retaining plate, through which the adjusting screw is inserted into the T-slot, and the other end of the adjusting screw is hexagonal.
[0013] Furthermore, a handwheel is installed at one end of the adjusting screw.
[0014] This utility model has the following beneficial effects:
[0015] 1. This utility model can arbitrarily adjust the row spacing of the transplanter, thereby adapting to the transplanting row spacing requirements of different crops, and has strong adaptability.
[0016] 2. This utility model adjusts the position of all seedling feeders and planters by using an adjustable screw, thereby adjusting the row spacing. It eliminates the need to repeatedly align the corresponding seedling feeders and planters, and also eliminates the need to repeatedly tap the seedling feeders and planters to move them, thereby reducing the alignment error of the seedling feeders and planters after the row spacing is adjusted, and preventing damage to the seedling feeders and planters caused by tapping.
[0017] 3. By switching between the separation state and the connection state of the half-threaded connector and the adjusting screw, the position of any group of seedling feeders and planters can be adjusted individually through one adjusting screw, without affecting other seedling feeders and planters.

It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the scope of the utility model.
[0025] like Figure 1-5 As shown, a crop seedling transplanting machine includes a frame 1. The frame 1 is equipped with a row spacing adjustment mechanism 2, wheels 3, a seedling feeding mechanism, and a planting mechanism. The axle of the wheel 3 is connected to a rotating shaft 5 mounted on the frame 1 via a sprocket mechanism 4. The rotating shaft 5 is connected to the planting mechanism and the seedling feeding mechanism via the sprocket mechanism 4. The row spacing adjustment mechanism 2 includes a spacing adjustment slide rail 6 and a load-bearing slide rail 7 mounted on the frame 1. Several spacing adjustment sliders 8 and several load-bearing sliders 9 are slidably connected to the spacing adjustment slide rail 6 and the load-bearing slide rail 7, respectively. A connecting box 10 is fixed to the bottom of the spacing adjustment slider 8. Two half-threaded connecting blocks 11 are slidably connected inside the connecting box 10. Several spacing adjustment sliders 8 are connected to a spacing adjustment screw 12 mounted on the frame 1 via the half-threaded connecting blocks 11.
[0026] The frame 1 is equipped with a seat 13, a seedling tray 14, and a hanging frame 15, and the planting mechanism is equipped with a soil covering wheel 16.
[0027] The seedling feeding mechanism includes a seedling feeding shaft 17 and several seedling feeders 18. The seedling feeding shaft 17 is rotatably mounted on the frame 1, and the drive end of the seedling feeder 18 is sleeved on the seedling feeding shaft 17.
[0028] The planting mechanism includes a planting shaft 19 and a planting device 20. The number of planting devices 20 is the same as the number of seedling feeders 18. The planting shaft 19 is rotatably mounted on the frame 1. The drive end of the planting device 20 is sleeved on the planting shaft 19. The seedling inlet end of the planting device 20 is located at the seedling outlet end of the corresponding seedling feeder 18.
[0029] The planter 20 and the seedling feeder 18 are existing technologies, and their structures and how they are fixed to the corresponding planting shaft 19 and seedling feeder 17 by means of bushings will not be described in detail.
[0030] Both the planting shaft 19 and the seedling feeding shaft 17 are hexagonal shafts. The rotating shaft 5 is connected to the planting shaft 19 of the planting mechanism and the seedling feeding shaft 17 of the seedling feeding mechanism through the sprocket mechanism 4, respectively.
[0031] Both the adjustable slider 8 and the load-bearing slider 9 are self-locking sliders. The number of adjustable sliders 8 and load-bearing sliders 9 is the same as the number of seedling feeders 18. The seedling feeders 18 are fixed on the corresponding load-bearing sliders 9. The load-bearing sliders 9 are connected to the corresponding adjustable sliders 8 through connecting rods 21. A positioning rod 22 is fixed at the bottom of the load-bearing slider 9. A flange (the inner diameter of the flange is larger than the outer contour of the planting shaft 19) is fixed at one end of the positioning rod 22. One end of the flange of the positioning rod 22 is sleeved on the planting shaft 19 and is located on one side of the corresponding planter 20.
[0032] The connecting box 10 is divided into two halves. Each half of the connecting box 10 contains a half-threaded connecting block 11. The side of the half-threaded connecting block 11 that contacts the adjusting screw 12 is semi-circular and has a thread that matches the adjusting screw 12. A T-slot 23 is provided on the half-threaded connecting block 11. An adjusting screw 24 is inserted into the T-slot 23. The adjusting screw 24 is threaded through and connected to the corresponding half-threaded connecting block 11. An adjusting nut 25 is threaded onto the outside of the adjusting screw 24 on the half-threaded connecting block 11.
[0033] One end of the adjusting screw 24 has a circular retaining plate 26, through which the adjusting screw 24 is inserted into the T-slot 23, and the other end of the adjusting screw 24 is hexagonal.
[0034] A handwheel 27 is installed at one end of the adjustable lead screw 12.
[0035] The working principle of this utility model is as follows:
[0036] During operation, the present invention is connected to an agricultural tractor via the suspension bracket 15. The operator sits on the seat 13. After starting, the wheels 3 rotate, which drives the rotating shaft 5 to rotate via the sprocket mechanism 4. The rotating shaft 5 drives the seedling feeding mechanism and the planting mechanism via the sprocket mechanism 4. When it is necessary to adjust the row spacing, first switch the spacing adjustment slider 8 and the load-bearing slider 9 to the sliding state, and then release the planter 20 of the planting mechanism and the seedling feeder 18 of the seedling feeding mechanism, so that the planter 20 and the seedling feeder 18 can slide on the planting shaft 19 and the seedling feeding shaft 17 respectively.
[0037] When the adjusting screw 24 is turned, the adjusting screw 24 drives the two half threaded blocks 11 to slide in the connecting box 10 through the clamping plate 26. When the two half threaded blocks 11 are away from the adjusting screw, the adjusting screw is not threaded with the two half threaded blocks 11, and the rotation of the adjusting screw will not drive the adjusting slider to move. At this time, it is in the separated state. When the two half threaded blocks 11 are in contact with the adjusting screw, the adjusting screw is threaded with the two half threaded blocks 11, and the rotation of the adjusting screw drives the adjusting slider to move. At this time, it is in the threaded state.
[0038] Adjust the two half-threaded blocks 11 in the connection box 10 corresponding to the seedling feeder 18 whose position needs to be adjusted to the threaded state using the adjusting screw 24, and then tighten the adjusting nut 25. Adjust the two half-threaded blocks 11 in the connection box 10 corresponding to the other seedling feeders 18 to the separated state using the adjusting screw 24. Attach the flange end of the positioning rod 22 corresponding to the planter 20 whose position needs to be adjusted to the planter 20 (with several shims separating the planter 20 from the flange end of the positioning rod 22). Then, rotate the handwheel 27 to rotate the adjusting screw 12. The adjusting sliders 8 corresponding to the two threaded blocks 11 in the threaded state move, causing the seedling feeder 18 connected via the connecting rod 21 to move, and the planter 20 connected via the positioning rod 22 to move. After adjustment, switch the adjusting slider 8 and the load-bearing slider 9 to the locked state, fix the seedling feeder 18 to the seedling feeding shaft 17, fix the planter 20 to the planting shaft 19, and loosen the bolt connection between the positioning rod 22 and the planter 20. This completes the position adjustment of one set of planters 20 and seedling feeders 18. Repeat this process for the other set of planters 20 and seedling feeders 18 until all adjustments are complete.
[0039] The above embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention.
