Description

Technical Field

[0001] The utility model relates to the technical field of rice transplanters, in particular to a rice transplanter with adjustable planting spacing. Background Art

[0002] A rice transplanter is an agricultural machine that plants rice seedlings in rice fields. Its main function is to improve the efficiency and quality of transplanting. The main structure of a rice transplanter includes a transplanting mechanism, a frame and a float. There are many types of rice transplanters on the market, and most of them have the function of automatically inserting the seedlings into the soil, which can greatly improve efficiency and save manpower.

[0003] The invention patent with the authorization announcement number CN110959347A discloses a motorized two-row rice transplanter, which includes a rice transplanting mechanism, a box transfer shaft, a rice tray, a running wheel, a gearbox, an engine, and a rice delivery mechanism. A frame, a rice tray bracket, and a handrail are fixedly installed on the support plate. A rice tray is fixedly installed above the rice tray bracket. A transmission box and a box transfer shaft are installed below the rice tray bracket. A running wheel, a gearbox, and an engine are installed on the frame in front of the support plate. The rice transplanting mechanism is located at the upper rear of the support plate. The transmission box drives the rice transplanting claw assembly to move through the rice transplanting claw transmission arm. The rice transplanting mechanism is a two-claw rice transplanting mechanism. The motorized two-row rice transplanter of the invention has the advantages of small size, light weight, flexibility, adjustable rice transplanting depth at any time, controllable forward speed of the rice transplanter, low production cost, convenient operation, low failure rate, safe and reliable use, and is particularly suitable for use in hilly areas, and has promotion value.

[0004] Although this technical solution has the advantages of small size, light weight, flexibility, adjustable transplanting depth at any time, and controllable forward speed of the transplanter, this technical method can complete two-row transplanting operations when used in practice, but the distance between the two rows of transplanting cannot be adjusted, which will cause the distance between the two rows of seedlings to be limited, which is not conducive to adjusting the spacing according to the actual conditions of the farmland for transplanting operations, causing inconvenience to users. In view of this, we propose a transplanter with adjustable planting spacing. Utility Model Content
