Description

Technical Field

[0001] This utility model belongs to the field of agricultural equipment technology, specifically to a locking device for a seedling feeder of a fully automatic transplanter. Background Technology

[0002] With the continuous development of agricultural technology, fully automatic transplanters are widely used in potted seedling planting. The seedling feeder, as an important component of the fully automatic transplanter, affects the working condition of the machine.

[0003] The seedling feeder works by using a drive sprocket to rotate a driven sprocket, gradually pushing the seedling tray with seedlings to the clamping position. Then, an automatic clamping device picks up the seedlings. The accuracy of the clamping device depends on the feeding position; if the feeding position is inaccurate, the clamping device will fail to pick up seedlings, resulting in fewer or missed seedlings and significant losses for the user. Due to inertia, the feeding device may not always be accurate in its forward movement. Summary of the Invention

[0004] This utility model provides a locking device for the seedling feeder of a fully automatic transplanter to ensure accurate seedling delivery position.

[0005] A locking device for a seedling feeder of a fully automatic transplanter includes a locking wheel assembly, a locking frame assembly, and a tension spring;

[0006] The locking wheel assembly includes a connecting sleeve, a fixed disc, and a locking pin; the connecting sleeve is fixed on the feeding disc drive shaft; two fixed discs are fixed on the connecting sleeve, and locking pins are connected at intervals at corresponding positions on the edges of the two fixed discs.

[0007] The locking frame assembly includes a locking frame fixing shaft and a locking crank arm. The locking frame fixing shaft is fixed on the frame, and the locking crank arm shaft is connected to the locking frame fixing shaft. The locking crank arm contacts between two locking fixing pins.

[0008] One end of the tension spring is connected to one end of the locking crank arm, and the other end is connected to the frame.

[0009] Furthermore, a rotating shaft is provided on the side of the locking crank arm that contacts the locking fixing pin.

[0010] Furthermore, a mounting sleeve is fixed on the frame, and a mounting rod extends out of the mounting sleeve, with the other end of the tension spring connected to the mounting rod.

[0011] Furthermore, a manual push rod is also formed on the outer support arm connected to the feed tray drive shaft.

[0012] The beneficial effects of this utility model are:

[0013] In this invention, a locking device is connected to the active shaft of the seedling feeding tray. Therefore, when the active wheel actively feeds the seedling tray, the active wheel and the locking wheel assembly rotate synchronously. When the seedling tray is fed forward in a row, the locking arm in the locking frame assembly moves from between the upper locking fixing pins to between the lower locking fixing pins. This avoids the influence of inertial force on the active wheel, ensures the accuracy of seedling feeding, and thus improves the seedling clamping accuracy of the seedling clamp, reduces problems such as missing seedlings and increases planting income.

[0014] In addition, in this utility model, a manual push rod is formed on the outer support arm. The manual push rod is connected to the power ratchet of the seedling feeder, which ensures that the seedlings can be manually fed in case of seedling tray jamming or cylinder failure, so as to ensure that the planting work can proceed normally.

[0022] The technical solution of the present invention will be further explained and illustrated below through specific embodiments.

[0023] Example 1

[0024] See appendix Figure 1-4 This utility model provides a locking device for the seedling feeder of a fully automatic transplanter, including a locking wheel assembly, a locking frame assembly, and a tension spring 1;

[0025] The locking wheel assembly includes a connecting sleeve 2, a fixed disc 3, and a locking pin 4; the connecting sleeve 2 is fixed on the feeding disc drive shaft 5; two fixed discs 3 are fixed on the connecting sleeve 2, and locking pins 4 are connected at intervals on the edges of the two fixed discs 3.

[0026] The locking frame assembly includes a locking frame fixing shaft 6 and a locking crank arm 7. The locking frame fixing shaft 6 is fixed on the frame, and the locking crank arm 7 is axially connected to the locking frame fixing shaft 6. The locking crank arm 7 contacts between two locking fixing pins 4. A rotating shaft 8 is provided on the side of the locking crank arm 7 that contacts the locking fixing pins 4.

[0027] One end of the tension spring is connected to one end of the locking crank arm 7. A mounting sleeve is fixed on the frame, and a mounting rod 9 extends out of the mounting sleeve. The other end of the tension spring is connected to the mounting rod 9. The locking frame assembly is kept in a locked state by the tension spring 1.

[0028] Example 2

[0029] See appendix Figure 5-6 On the drive shaft 5 for feeding the seedling tray, a manual push rod 11 is also formed on the outer support arm 10. The outer support arm 10 and the manual push rod 11 are an integral metal plate. The manual push rod 11 is connected to the power ratchet of the seedling feeder, ensuring that seedlings can be manually fed even if the seedling tray is jammed or the cylinder 12 fails, thus ensuring that the planting work can proceed normally. The power ratchet and other structures are described in Chinese patent document CN222073881U, patent title: A Fully Automatic Transplanter Seedling Feeding Device, and will not be repeated here.

[0030] When in use, the active wheel 13 of the seedling feeder drives the passive wheel 14 to rotate step by step, which in turn drives the locking wheel assembly to rotate. The locking shaft 8 is locked between the two locking pins 4, thus ensuring that the seedling feeder will not cause the seedlings to be delivered inaccurately due to inertia.

[0031] Manual push rod 11 allows for manual feeding of seedlings in case the seedling tray is stuck or the cylinder fails, ensuring that the planting work can proceed normally.
