Description

Soil-covering mechanism for plug seedling seeding machine

technical field

The utility model relates to a soil-covering mechanism of a planter of agricultural machinery, in particular to a soil-covering mechanism of an automatic seeder for mechanized plug seedling cultivation, and belongs to the technical field of precision agricultural machinery.

Background technique

At present, as a new seedling and sowing method in the modern agriculture, forestry and flower industry, the technology of plug seedling cultivation and sowing has achieved great development and application at home and abroad. The plug seedling production line at home and abroad generally fills the plug with substrate or mixed soil first, then makes holes in the plug with the substrate installed, and then completes the sowing operation in the plug that has been punched. The plug tray also needs to cover some substrate on its surface, and finally perform a watering operation. When covering soil mechanically, the soil covering roller or conveyor belt generally drives the substrate to cover the hole tray, but during the soil covering process, no matter whether the hole tray enters the soil covering mechanism or not, the soil covering device is constantly dropping material, resulting in matrix or mixed soil. A large amount of waste, but also brings great difficulties to the recycling work. Therefore, it is very important to realize automatic control and accurate soil covering process.

Contents of the invention

The purpose of this utility model is to overcome the problems existing in the prior art, to design and provide a kind of soil covering mechanism for the automatic seeding machine of mechanized plug seedling raising. Covered on the plug tray, the structure is simple, the work is reliable, and it can meet the soil covering requirement of the mechanized plug seedling raising production line.

The purpose of this utility model is achieved in this way: a soil-covering mechanism for a hole tray seedling planter, including a frame, a hole tray, a travel switch, a conveyor belt, a material box, an adjustment handle, a servo motor, an adjustment side plate, an adjustment plate, and a soil cover The roller and the adjusting bolt are characterized in that: a limit switch, a conveyor belt and a material box are installed on the frame of the workbench, and the conveyor belt passes through the bottom of the material box; the soil covering roller is installed under the material box outlet, and the servo motor is installed The side of the material box is connected with the shaft head of the soil-covering drum; the adjusting side plate is installed on the inside of the material box through the adjusting handle, and the adjusting plate is installed on the outside of the outlet of the material box through the adjusting bolt.

As a design of the soil-covering mechanism of a plug seedling seeding planter of the present invention: the outer surface of the soil-covering drum is provided with a number of equidistant rectangular tooth-shaped grooves.

As a design of the soil-covering mechanism of the plug seedling seeding machine of the utility model: two long holes with the same size and shape are opened on the adjustment plate.

The beneficial effects of the utility model are: the amount of covering soil can be adjusted, and the width of the covering soil can be adjusted according to the width of the hole tray; the automatic and precise control is adopted to realize the mechanical covering of soil, and in the process of the transmission conveyor belt continuously working to transport the hole tray, The soil covering mechanism starts to cover soil only when the plug tray enters the predetermined soil covering position, so as to realize accurate soil covering and avoid waste of raw materials such as matrix or mixed soil.

Detailed ways

The best implementation of the soil covering mechanism of a plug seedling planter of the present invention will be described in detail below in conjunction with the accompanying drawings.

The utility model comprises a frame (1), a tray (2), a travel switch (3), a conveyor belt (4), a material box (5), an adjustment handle (6), a servo motor (7), an adjustment side plate ( 8), soil covering drum (9), adjusting plate (10), adjusting bolt (11), characterized in that: a travel switch (3), a conveyor belt (4) and a material are installed on the frame (1) of the workbench The box (5), the conveyor belt (4) passes under the material box (5); the soil covering roller (9) is installed under the material box (5) outlet, and the servo motor (7) is installed on the side of the material box (5) It is connected with the shaft head of the soil covering drum (9); the adjusting side plate (8) is installed on the inside of the material box (5) through the adjusting handle (6), and the adjusting plate (10) is installed on the material box (5) through the adjusting bolt (11) The outer side of the discharge port; the circumference of the outer surface of the covering cylinder (9) has several equidistant rectangular tooth-shaped grooves; the adjusting plate (10) has two long holes with the same size and shape.

Working process and principle of the present utility model are as follows:

During operation, when the conveyor belt (4) transports the tray (2) and touches the travel switch (3), the travel switch (3) sends a delay pulse signal to the servo motor (7), and when the tray (2) is conveyed When the belt (4) runs under the material box (5), the servo motor (7) starts to drive the soil-covering drum (9) to rotate at a certain angle, and the substrate falls from the groove of the soil-covering drum (9) to the soil where the seeds have been sown. Holes are filled up on the hole plate (2). By adjusting the handle (6), the adjustment side plate (8) can be moved left and right, thereby changing the distance D between the two adjustment side plates (8) installed in the material box (5), and then changing the covering soil width to adapt to different widths The size of the tray (2); the adjustment plate (10) can be moved up and down by adjusting the adjustment bolt (11) installed on the outside of the discharge port of the material box (5), thereby changing the adjustment plate (10) and the earth-covering drum (9) The gap H between them will change the size of the covering soil.

The utility model has the advantages of simple structure, convenient and reliable control, and can automatically complete the soil-covering process for the sown plugs, is suitable for plugs of various sizes and specifications, and can meet the needs of different production scales.
