Description

Technical field [0001] The invention relates to an efficient automatic feeding device for pot seedlings, which is applied to pot seedling transplanting machines for vegetables, flowers, tea, etc., and belongs to the technical field of agricultural machinery. Background technique [0002] The main advantages of pot seedling transplanting are as follows: ① Shorten the growth cycle, facilitate cropping arrangements, and improve land utilization; ② After transplanting, the root system of pot seedlings is developed, which can provide convenient conditions for subsequent management and other links. Vegetable and flower production has always been a labor-intensive industry. Due to the lack of suitable supporting machinery, its labor cost accounts for more than 50% of the production cost. Manual transplanting operations are labor-intensive, low-efficiency, poor-quality, and difficult to transplant. The realization of large-scale transplantation has led to small production scale and low p...

Problems solved by technology

[0003] The function of the seedling feeding device is to send the seedlings into the planter in real time. Most of the seedling feeding devices of the existing semi-automatic transplanting machines use a rotating cup mechanism, which can only feed one seedling at a time and cannot be operated intermittently; The labor intensity is high, and people are prone to fatigue, resulting in missing seedlings and reducing the quality of transplanting; affected by manual operation, the transplanting speed is slow

The automatic transplanting machine has a set of automatic seedling feeding mechanism, which increases the transplanting speed and does not require manual seedling feeding, but the whole mechanism is relatively complicated and the cost is high, so it is not suitable for small and medium-sized users

[0004] The invention patent "Automatic Seedling Feeding Mechanism for Plug Seedling Transplanting (Application No. 201210317407.8)" discloses an automatic feeding device for plug seedling transplanting, which includes a shifting mechanism, a bracket, a sliding Rod, connecting rod mechanism and seedling clamping mechanism. The bracket is set on the shifting mechanism to realize the position conversion of the bracket between the seedling picking and seedling feeding actions. One end of the sliding rod is inserted into the sliding sleeve that can move in the chute on the bracket Inside, the other end is connected with the seedling clamping mechanism, and the shifting mechanism realizes the transition between the seedling picking and seedling feeding process positions of the seedling clamping mechanism, controls the rotation of the sliding bar and the seedling clamping mechanism through the connecting rod mechanism, and realizes the closing of the seedling clamp and open, the structure of the device is more complex, the production cost is higher, and its clamping mechanism cannot accurately locate the pot seedling position during the seedling clamping process, which may easily lead to seedling leakage

The invention patent "Mechanical Seedling Feeding and Transplanting Machine (Application No. 2011101335051)" discloses a mechanical feeding and transplanting machine that replaces manual feeding of seedlings into the seedling cups of the mechanical seedling feeding system. The seeds are moved into the mechanical seedling feeding device synchronously. The seedling feeding device is automatically controlled by the electrical control system of the transplanting machine to improve the speed and efficiency of transplanting operations and reduce production costs. However, the design of the seedling feeding device is complicated and there are many parts. In addition, it adopts The continuous transmission of the transmission chain will cause discontinuity when the pot seedlings are fed twice, resulting in the wrong timing of the cup and pot seedlings when the pot seedlings fall into the cup, which will cause the pot seedlings to miss planting and reduce the quality of transplanting
