Array type rice transplanter

Abstract

The invention discloses an array type rice transplanter. The array type rice transplanter comprises a travelling mechanism, and a rack arranged on the travelling mechanism, wherein a seedling plate assembly and a rice seedling transplanting mechanism are arranged on the rack; the seedling plate assembly comprises a gridded seedling plate which is arranged on the rack and is vertical to the horizontal plane, a vertical guide mechanism, and a stepping dropping driving mechanism for driving the gridded seedling plate to gradually downwards move at fixed distance; the sowing mechanism comprises a rice seedling propping pin, a rice seedling propping pin bracket, a rice seedling propping pin driving mechanism and a rice seedling propping pin bracket driving mechanism; the rice seedling propping pin is horizontally arranged on the rice seedling propping pin bracket; the rice seedling propping pin driving mechanism comprises a rice seedling propping mechanism for pushing the rice seedling propping pin to move towards the gridded rice seedling plate, and a restoring mechanism for pushing the rice seedling propping pin to restore; the rice seedling propping pin bracket driving mechanism comprises a power mechanism for driving the rice seedling propping pin bracket to move at fixed distance by reciprocating in the direction vertical to the movement direction of the rice seedling propping pin. The array type rice transplanter has the advantages of large number of one-time loading of the seedling plate, small size, light weight, high working efficiency, convenience in transplanting of the rice seedlings, and prevention of automatic falling of the rice seedlings.

Description

technical field [0001] The invention relates to a machine for raising seedlings of crops and transplanting with soil, in particular to an array sowing seedling machine for seedlings with soil. Background technique [0002] At present, the known rice planting machines are mainly divided into two categories: 1. Traditional rice transplanters based on manipulators (claws) to tear and cut blanket-shaped seedling roots to plant in pockets; Rice transplanter; Among them, the first type of rice planting machinery technology is relatively mature, and the planting operation is driven by the engine at high frequency to achieve high planting efficiency. Seedling roots and transplanting rice seedlings into the mud require a lot of power and require high strength of mechanical materials. The mechanism is usually cumbersome, the cost of consumables and energy consumption is high, and it is inconvenient to operate in hilly rice fields. The advantage of the second type of rice planting mac...

Problems solved by technology

[0002] At present, the known rice planting machines are mainly divided into two categories: 1. Traditional rice transplanters based on manipulators (claws) to tear and cut blanket-shaped seedling roots to plant in pockets; Rice transplanter; Among them, the first type of rice planting machine technology is relatively mature, and the planting operation is driven by the engine at high frequency to achieve high planting efficiency. Seedling roots and transplanting seedlings into the mud require a lot of power and require high strength of mechanical materials. The mechanism is usually cumbersome, the cost of consumables and energy consumption is high, and it is inconvenient to operate in hilly rice areas.

[0004] 1. Since the seedling trays are placed horizontally, in order to increase the sowing area of ​​a single loaded seedling tray, it is necessary to place multiple seedling trays horizontally on the seedling tray fixing frame, but the more seedling trays, the larger the horizontal space occupied. The volume will be larger; and if the number of seedling trays is too small, the sowing area of ​​a single loading of seedling trays is small, and the number of times to stop and load seedling trays during operation will be large, resulting in low efficiency and high labor intensity.

[0005] 2. Since the seedlings are facing downward during operation, the shaking of the seedling machine during the movement may cause the gravity of the seedlings to be greater than the sticking force between the root mud and the side wall of the seedling tray, causing some seedlings to automatically fall downwards , affecting normal sowing operations

[0006] 3. Since the seedlings are facing downwards and the roots are facing upwards during operation, the roots of the seedlings need to roll for half a circle before they fall to the mud after being pushed out of the seedling tray by the transplanting pole. Therefore, the distance between the seedling tray and the paddy field must be large enough to prevent machine too tall
