Description

Technical Field

[0001] This invention relates to the field of agricultural planting machinery technology, specifically to a tray delivery mechanism for a transplanter with a seedling pressing tray function. Background Technology

[0002] With the continuous development of agriculture in my country, pot seedling transplanting technology has been widely used. This technology allows seedlings to effectively avoid the impact of severe weather such as low temperatures and strong winds, greatly improving the survival rate and yield. Currently, the driving mechanism of the seedling delivery device in existing pot seedling transplanters is driven by the machine's ground wheels and power transmission device. Furthermore, existing pot seedling transplanters load seedlings into seedling trays, and the delivery device sequentially transports multiple trays to the seedling-grabbing claws for transplanting.

[0003] Currently, the tray delivery device of existing seedling transplanters has a poor fit between the seedling tray and the delivery device. When the delivery device carries the seedling tray, the seedling tray will fluctuate and vibrate. Especially when the seedling tray moves to the front arc section of the delivery device, the edge of the seedling tray often separates from the delivery device. This often causes the seedling tray to get stuck or even be damaged, affecting the normal operation of the seedling taking device, making the transplanting operation difficult, and even causing equipment damage and delaying the planting season.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example:

[0025] like Figures 1-5As shown, this embodiment of the invention provides a tray delivery mechanism for a transplanter with a seedling pressing tray function, including two frame plates 11, a second cylinder 8 mounted on one side of the frame plate 11 via a fixing plate 9, and two rotating shafts 10 mounted between the ends of the two frame plates 11 by rotation, and a drive assembly 7 located at both ends of one of the rotating shafts 10 to drive rotation. A connecting plate 12 is fixedly provided at the midpoint of the opposite side of the two frame plates 11, and a side plate 14 is fixedly provided at the midpoint of one side of the connecting plate 12. Two mounting bolts 13 are fixedly installed on the upper end of the side plate 14, and guide rods 3 are welded to the upper end of the two mounting bolts 13. Sprockets 1 are fixedly provided at both ends of the two rotating shafts 10 on the inner side of the two frame plates 11. Two horizontally parallel sprockets 1 are connected by chains 4. Multiple guide rods 5 are fixedly provided at equal intervals at the lower end of the outer sleeve of the pin shaft in the two chains 4.

[0026] The drive assembly 7 includes a ratchet 701 fixedly sleeved on the rotating shaft 10, a locking unlocking arm 708 rotatably sleeved on the rotating shaft 10 at the rear end of the displacement ratchet 701, a locking reset seat 707 rotatably sleeved on the rotating shaft 10 at the front end of the ratchet 701, a ratchet lock 705 for locking the ratchet 701, and a manual / automatic conversion handle 704. A first fixed post 706 is rotatably sleeved at the lower end of the ratchet lock 705, a third fixed post 7011 is rotatably sleeved at the lower end of the manual / automatic conversion handle 704, a second fixed post 7010 is rotatably sleeved at the lower end of one side of the outer wall of the frame plate 11 located on one side of the manual / automatic conversion handle 704, a pawl 702 is installed at the upper end of the front end face of the locking unlocking arm 708, and a cylinder 2 is fixedly installed on one side of the upper end face of both frame plates 11.

[0027] Specifically, the working principle of this invention is as follows:

[0028] In use, the seedling tray is placed on the upper end of the guide rod 5 inside the shelf plate 11, with the upper surface of the seedling tray below the top surface of the shelf plate 11. Then, by starting the second cylinder 8, the drive assembly 7 is driven to move by the push of the second cylinder 8. That is, the output end of the second cylinder 8 pushes the locking unlocking arm 708 to rotate. When the locking unlocking arm 708 rotates, it will squeeze the unlocking wheel set on the upper rear side of the ratchet lock 705, causing the ratchet lock 705 to rotate. At the same time, the locking unlocking arm... The pawl 702 on 708 also moves, at which time the ratchet 701 can rotate; when the second cylinder 8 is reset, it drives the locking device unlocking arm 708 to reset. During the reset process, the upper pawl 702 will push the ratchet 701 to rotate, and the ratchet locking device 705 is reset under the action of the restoring tension of the locking spring 709 on the locking device reset seat 707 and is locked in the tooth groove of the ratchet 701, thereby realizing the one-angle rotation and locking function of the ratchet 701.

[0029] Since the ratchet 701 is fixedly connected to the rotating shaft 10, the rotation of the ratchet 701 drives the rotating shaft 10 to rotate, and the rotation of the rotating shaft 10 drives the inner sprocket 1 to rotate. Under the transmission of the chain 4, multiple sprockets 1 rotate together. When the chain 4 rotates, it drives the guide rod 5 to move, which in turn drives the seedling tray placed at the upper end to move together, thereby realizing the function of automatically feeding the seedling tray. The first cylinder 2 located on the frame plate 11 extends outward every time the seedling tray moves forward, so that it is located at the upper end of the edge of the seedling tray body to play a limiting role. After the transplanter takes away the seedling, it retracts and resets, effectively preventing the seedling tray from accidentally detaching.

[0030] In one embodiment of the present invention, the pawl 702 is connected to the manual / automatic conversion handle 704 by a connecting rope 703, and the manual / automatic conversion handle 704 is also connected to the ratchet lock 705 by a connecting rope 703. Specifically, the design of the manual / automatic conversion handle 704 helps to manually push the seedling tray forward to the seedling picking position, realizing a manual-automatic integrated structure design, which can quickly solve the problem of seedlings not being delivered in place.

[0031] In one embodiment of the present invention, one end of the ratchet locking device 705 is connected to one end of the locking device reset seat 707 via a locking tension spring 709. The locking device reset seat 707 has three endpoints, one of which is rotatably connected to the rotating shaft 10, and the remaining two ends are respectively connected to the first fixing post 706 and the second fixing post 7010 and locked by nuts. Specifically, all three endpoints of the locking device reset seat 707 are fixed, so that the locking device reset seat 707 cannot move, and the locking tension spring... One end of the spring 709 is fixed to the locking device reset seat 707, and the other end is connected to the ratchet locking device 705. When the ratchet locking device 705 rotates, it will cause the locking spring 709 to deform and stretch. When the ratchet locking device 705 exerts a squeezing force, the locking spring 709 will contract and reset, thereby completing the automatic reset function of the ratchet locking device 705. The end of the ratchet locking device 705 near the ratchet 701 is provided with a 75-degree angle locking tooth, which is convenient to cut into the tooth groove of the ratchet 701, and the locking is reliable.

[0032] In one embodiment of the present invention, the first fixing column 706, the second fixing column 7010 and the third fixing column 7011 are all fixedly installed on the outer wall of the frame plate 11, which specifically ensures the stability of the entire structural component and that each component is stable and does not interfere with the others.

[0033] In one embodiment of the present invention, the output extension end of the second cylinder 8 is connected to the lower end of the locking device unlocking arm 708. Specifically, this enables the rapid linkage effect of cylinder extension and retraction, facilitating continuous linkage control.

[0034] In one embodiment of the present invention, a partition 6 is fixedly provided at the upper side of one end of the two opposing sides of the shelf 11. The upper side of the partition 6 is inclined downward. Specifically, it can play an auxiliary guiding role when placing the seedling tray, making the placement of the seedling tray smoother and more convenient.

[0035] In one embodiment of the present invention, the diameter of the sprocket 1 on the shaft 10 closer to the partition 6 is smaller than the diameter of the sprocket 1 on the shaft 10 farther from the partition 6. The two drive components 7 are installed at both ends of the shaft 10 closer to the partition 6. Specifically, this can better adapt to the shape and structure of the frame plate 11 and ensure that it will not be disturbed during the transmission process.

[0036] In one embodiment of the present invention, baffles are fixedly provided at the output ends of both cylinders 2 to prevent the seedling tray from tilting. When the seedling tray moves forward once, cylinder 2 extends outward, causing the baffles to be located at the upper end of the side of the seedling tray to play an auxiliary blocking role, so as to prevent the transplanter from pulling the seedling tray off the track when it removes the seedlings from the seedling tray. At the same time, after the seedlings are removed, cylinder 2 resets, so as not to affect the subsequent movement of the seedling tray.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
