Potted seedling jacking device based on incomplete rack and pinion mechanism

Abstract

The invention discloses a potted seedling jacking device based on an incomplete rack and pinion mechanism. The present potted seedling picking device adopts a pulling type seedling picking mode in the manner of clamping the seedling roots by inserting a seedling needle into a potted seedling matrix or directly clamping the seedling stems, and therefore, the seedling root system and the matrix structure are easily damaged and the seedlings require a certain growth recovery period. The potted seedling jacking device comprises an incomplete rack and pinion component, a bearing support base component, a resetting spring and a jacking rod; a motor is used for inputting power to an incomplete gear shaft and driving the incomplete gear to continuously rotate; after the incomplete gear starts to mesh with a straight tooth rack, the power is transferred to the jacking rod so as to start to jack the seedlings; the resetting spring is arranged on the jacking rod; after the ending of the seedling jacking, the jacking rod returns to an initial position under the effect of the resetting spring. The potted seedling jacking device has the advantages that the incomplete rack and pinion mechanism has a simple structure, is easily manufactured and can reliably work; the motion time and the static time of the rack can be changed within a wider scope, the rack is suitable for low-speed light-load occasions and can drive the driven component to intermittently move; a contact area between the end part of the jacking rod and the matrix is large; the jacking rod is not inserted into the matrix and cannot damage the seedling roots in the seedling jacking process.

Description

technical field [0001] The invention belongs to the field of agricultural mechanization research, and relates to a plug seedling topping device based on an incomplete rack and pinion mechanism. Background technique [0002] Seedling cultivation and transplanting technology is a new type of cultivation technology, which has great advantages over direct seeding. It is specifically manifested in: it can prevent crops from being affected by harsh climates such as cold in late spring and low temperature in early spring, improve the survival rate of seedlings, and ensure that crops meet agronomic requirements. It can prolong the growth period of crops and effectively improve the yield and quality of crops per mu. [0003] At present, domestic planting operations mostly use seedling raising and transplanting technology. The operation is mainly based on the hanging basket semi-automatic transplanting machine. The seedlings are taken and fed manually, and the planting is completed by...

Problems solved by technology

[0003] At present, domestic planting operations mostly use seedling raising and transplanting technology. The operation is mainly based on the hanging basket semi-automatic transplanting machine. The seedlings are picked and fed manually, and the planting is completed by machinery. The degree of automation is low, the labor intensity is high, and the efficiency is low. increase the leakage rate
