An automatic stacking device for rice seedling trays

Abstract

The invention discloses an automatic rice seedling plate overlapping device. The automatic rice seedling plate overlapping device comprises a stand, and a seedling plate conveying mechanism, a seedling plate stacking mechanism and a leak-proof soil filling mechanism arranged on the stand, the seedling plate stacking mechanism is provided with turn fingers through pins, the turn fingers are capable of rotating around the pins and restoring automatically, the turn fingers ascend and descend through a seedling plate lifting cylinder, when ascending, the turn fingers can support the edge of a seedling plate to be overlapped conveyed through the seedling plate conveying mechanism so as to support the seedling plate to be overlapped, when descending, when the turn fingers touch the edge of the seedling plate to be overlapped conveyed through the seedling plate conveying mechanism again, the turn fingers can rotate towards the upside so as to successfully descend to the downside of the edge of the seedling plate to be overlapped, and then the turn fingers reset to support the seedling plate to be overlapped again; the leak-proof soil filling mechanism covers the uppermost seedling plates supported by the turn fingers through a cover plate thereof, and the leak-proof soil filling mechanism slides up and down along with the ascending and descending of the seedling plates so as to prevent seeds and soil in the seedling plates splashing down or moving in the plate overlapping process. The automatic rice seedling plate overlapping device is capable of automatically stacking seedling plates, reliable in work and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an automatic stacking device for rice seedling trays. Background technique [0002] Industrial rice seedling raising is an important link in the rice mechanized production process, mainly including the process of feeding trays, laying subsoil, sowing, covering topsoil, spraying water and taking trays. At present, most of the rice seedling seeding machines are mainly manually removed one by one. According to experience, when the rice seedling seeding machine is 600 trays per hour, an average of 2 to 3 workers are needed to complete the tray removal. It is difficult to improve the machine efficiency. It has become an important factor restricting the production efficiency of the rice seedling planter; and the workers who take the tray need to bend down frequently to pick up and put the tray in a very short time interval, and the actions are repeated, which is easy to ...

At present, most of the rice seedling seeding machines are mainly manually removed one by one. According to experience, when the rice seedling seeding machine is 600 trays per hour, an average of 2 to 3 workers are needed to complete the tray removal. It is difficult to improve the machine efficiency. It has become an important factor restricting the production efficiency of the rice seedling seeding machine; and the workers who take the tray need to bend down frequently to pick up and put the tray in a very short time interval, and the actions are repeated, which is easy to cause fatigue damage

[0003] At present, there are also related automatic stacking device products at home and abroad, involving equipment such as rice, vegetables and flowers, mainly targeting hard seedling trays. However, due to the high cost of hard seedling trays, the use of soft seedling trays with trays is more Wider and wider, but the soft seedling tray is more likely to splash seeds and soil out of the seedling tray when vibrating, affecting its uniformity

After research, the current automatic stacking device products are mainly divided into two types. One kind of stacking speed is stable, which will not cause the movement of the seed and soil position during the stacking process, but the speed is slow and the efficiency is low; the other stacking The disk speed is fast and the impact is relatively large, so it is only suitable for hard seedling disks with strong shock resistance
