Device and method with pot seedling feeding speed capable of being adjusted automatically

Abstract

The invention discloses a device and method with the pot seedling feeding speed capable of being adjusted automatically. The device mainly comprises a pot seedling shovel, a transferring unit, a detection sensor, a controller, a seedling distributing unit, side plates and a support. The transferring unit comprises a servo motor, a transmission shaft, a conveying belt, a tensioning shaft and a bearing. The seedling distributing unit comprises a seedling distributing rod, reset springs, a guide pillar and a support. Pot seedlings are placed into the transferring unit by an operator through the pot seedling shovel, the controller controls the servo motor to drive the conveying belt and drive the pot seedlings to move, when a planting device is connected with a seedling barrel to ascend to the seedling receiving position, the seedling distributing rod is controlled by the planting device to be ejected, meanwhile, the servo motor is driven to drive the pot seedlings to move forwards, the pot seedlings are connected with the seedling barrel under the action of gravity, the seedling distributing rod enables the feeding postures of the pot seedlings to be strengthened at the moment the pot seedlings fall off, and accordingly the planting quality of the pot seedlings can be improved. According to the device and method, automation for conveying and seedling distributing of the pot seedlings in the transplanting mechanical operation process is achieved, overfatigue caused by frequent action repetition and nervous tension happening due to the fact that people are afraid of seedling leakage in a traditional manual seedling feeding method are avoided, the structure is simple, operation is convenient and fast, and planting efficiency and quality are improved.

Description

technical field [0001] The invention relates to a high-efficiency pot seedling feeding mechanism, which is applied to pot seedling transplanting machines for vegetables and flowers, and belongs to the technical field of agricultural machinery. Background technique [0002] The main advantages of pot seedling transplanting are as follows: ①Shorten the growth cycle, facilitate the stubble arrangement, and improve land utilization; ②The root system of pot seedlings is developed after transplanting, which can provide convenient conditions for subsequent management and other links. The production of vegetables and flowers 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 is labor-intensive, low in efficiency, poor in transplanting quality, and difficult to produce. Realization of large-scale transplanting leads to small production scale and low product...

Problems solved by technology

[0003] The function of the seedling feeding mechanism is to send the potted seedlings into the planter in real time. Most of the seedling feeding mechanisms 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 Transplanting Plug Seedlings (Application No. 201210317407.8)" discloses an automatic seedling-feeding mechanism for transplanting plug-in seedlings, 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 mechanism synchronously. The seedling feeding mechanism is automatically controlled by the electric 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 mechanism is complicated and there are many parts. In addition, it uses 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
