A rice seedling raising device

Abstract

The invention provides a rice seedling raising device. The seedling raising device includes a material feeding and leveling device, a movable extension rail, a pulley and a material spreading device. There is a trolley on which the paving device is installed. The movable extension rail includes a first carriage and a second carriage. The bottom of the first carriage is vertically provided with two first electric telescopic rods on the ground. The surface is provided with a first rack, and a second carriage is slid on the outer wall of the first carriage. The second carriage is parallel to the first carriage, and a friction wheel is provided in the first carriage. The upper surface of the second sliding frame is provided with a second rack, and the bottom of the second sliding frame is provided with two second electric telescopic rods perpendicular to the ground. The invention can realize the automatic parallel extension of the slide rail of the seedling raising device, and improves the sowing efficiency through integrated operation.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a rice seedling raising device. Background technique [0002] Rice seedling raising technology is a commonly used seedling raising technology. This technology has short seedling age, strong seedlings, convenient management, intensive seedling raising and professional production. This seedling sowing method requires uniform seeding, and the amount of seeds per tray must be accurate. In order to ensure uniform spreading, it is necessary to lay tracks on the field in advance, and install the spreading machine on the pre-laid tracks. When breeding When the area is large, the track needs to be set very long, the parallelism of the track needs to be adjusted during the laying process, and the land needs to be specially leveled, making the breeding operation inflexible. Moreover, traditional devices cannot be operated in an integrated manner, requiring manual...

Problems solved by technology

This seedling sowing method requires uniform seeding, and the amount of seeds per tray must be accurate. In order to ensure uniform spreading, it is necessary to lay tracks on the field in advance, and install the spreading machine on the pre-laid tracks. When breeding When the area is large, the track needs to be set very long. During the laying process, the parallelism of the track needs to be adjusted, and the land needs to be specially leveled. The breeding operation is not flexible.

Moreover, traditional devices cannot be operated in an integrated manner, requiring manual multi-step fabrication, low breeding efficiency, and high requirements for personnel operations. Therefore, it is necessary to design a new type of breeding device to solve the above problems
