Description

Technical Field

[0001] The utility model belongs to the field of new energy agricultural machinery and unmanned driving technology, and in particular relates to an electric unmanned driving rice transplanter. Background Art

[0002] Currently, most rice transplanters are powered by diesel engines, which present issues such as high noise, complex transmission, low efficiency, and severe environmental pollution. With the development of society and advancement of technology, energy depletion and environmental pollution are attracting increasing attention. Saving energy and reducing environmental pollution are key issues for the sustainable development of agricultural mechanization.

[0003] At present, rice planting mainly relies on manual and more traditional mechanical transplanting. Manual rice planting requires a large investment, and the quality and efficiency of transplanting are difficult to guarantee. There is a situation where seedlings are trampled and wasted. For traditional riding transplanters, the quality of transplanting depends on the driving level of the transplanter driver. When the driver is tired or not paying attention, problems such as low straightness, missed transplanting and repeated transplanting will occur, which will make it difficult to manage in the later stage and ultimately lead to reduced rice yields.

[0004] Electric rice transplanters transmit energy in the form of electricity, significantly simplifying the transmission mechanism and reducing overall machine weight, losses, and emissions. Furthermore, the motor's strong speed regulation enhances the transplanter's maneuverability. They also possess the general advantages of electric machinery, such as low noise, no exhaust emissions, and no secondary energy consumption. This achieves zero emissions and pollution, fulfilling the principles of green agriculture. Therefore, combining the advantages of new energy and unmanned intelligent driving, we propose an electric, unmanned rice transplanter to improve transplanting efficiency and quality.

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0037] Reference Figures 1 to 4 The utility model discloses an electric unmanned rice transplanter, comprising a main frame 17, a rice transplanting system mounted at the rear end of the main frame 17 via a traction bracket 5, a front drive wheel 1 rotatably arranged at the front end of the main frame 17 in the direction of travel, a rear drive wheel 2 rotatably arranged at the rear end of the main frame 17 in the direction of travel, and a traction motor 16 serving as a power source.

The seedling box is fixedly connected to the box-moving shaft 41, which drives the box in a horizontal reciprocating motion, achieving horizontal seedling delivery. The active cam 37 on the screw shaft 38 moves the driven cam 39 on the seedling delivery shaft 40, causing the delivery shaft 40 to rotate for longitudinal seedling delivery. The planetary gear 26 acts as a transfer mechanism, automatically distributing power according to the load on the front and rear wheels, synchronizing the transplanter's travel speed, planting frequency, and the speed of seedling delivery.
