Rice transplanter with soil preparation function

Abstract

The invention discloses a rice transplanter with a soil preparation function, and belongs to the field of agricultural mechanical equipment. The rice transplanter comprises a machine body, a seedling table connected behind the machine body, and a soil preparation device arranged between the machine body and the seedling table; the soil preparation device comprises a swing arm vertically arranged between the machine body and the seedling table, a soil preparation part horizontally arranged and fixedly connected with the bottom end of the swing arm, a lower connecting arm, an upper suspension frame, a fixing part fixedly connected with the seedling table, and a handle. One end of the lower connecting arm is hinged with the swing arm, and the other end is hinged with the seedling table; the upper suspension frame is horizontally arranged at the upper part of the swing arm and rotationally connected with the seedling table; the upper suspension frame is in transmission connection with the swing arm; one end of the handle is in transmission connection with the upper suspension frame; the handle is in matched connection with the fixing part; and a plurality of gears for clamping and fixing the handle are arranged on the fixing part. By arranging the soil preparation device, different soil preparation height position requirements can be met, so that the soil preparation action is effectively completed in the seedling platform operation process, the seedling table obtains a better seedling transplanting effect, and the rice transplanter has the advantages of being easy to operate and reasonable in design.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and equipment, and more specifically relates to a rice transplanter with the function of soil preparation. Background technique [0002] The rice transplanter is an agricultural machine for implanting rice seedlings into the paddy field. It is mainly composed of a body 1 and a seedling platform 2. In order to adapt to complex working conditions and obtain better rice transplanting effects, a soil preparation machine is installed on the rice transplanter's seedling platform 2. Device 3 is particularly important. [0003] In the prior art, the soil preparation device 3 is generally hard-connected to the seedling platform 2. When a bump suddenly appears on the ground surface, it is difficult for the soil preparation roller of the soil preparation device to rise quickly and automatically. Push mud or even damage the adjustment mechanism; in some existing patent applications, the height of the so...

Problems solved by technology

[0003] In the prior art, the soil preparation device 3 is generally hard-connected to the seedling platform 2. When a bump suddenly appears on the ground surface, it is difficult for the soil preparation roller of the soil preparation device to rise quickly and automatically. Push mud or even damage the adjustment mechanism; in some existing patent applications, the height of the soil preparation roller is automatically controlled by the motor. This kind of method can realize real-time control of the height of the soil preparation roller in theory, but the implementation cost is high, and because the seedling platform 2 The planting parts are immersed in muddy water for a long time, which shortens the life of the motor, so it is not commonly used in practice.
