Problems solved by technology

In the past, the seedling trays were usually moved outside the pond for leaf cutting, which not only wasted a lot of manpower and precious nutrient solution, but also caused damage to the tobacco seedlings during the moving process.
Manual pruning with scissors has problems such as low work efficiency, high labor intensity and high cost of leaf cutting, and it is easy to cause disease infection during pruning
The semi-automatic leaf cutting equipment for tobacco seedlings recently developed on the market has low operating efficiency. The leaf cutting trolley is pulled by a steel wire rope manually, and the speed is uneven; the leaf cutting frame walks on a plane, without guide rails, and the straightness is low. Manually push the leaf cutting equipment , the leaf shearing frame is easy to deviate; the transfer between spans is difficult, and manual movement is required; the transmission cable needs manual auxiliary transportation and retraction, which is easy to entangle the cables; the leaf shearing equipment frame is short, and the leaf shearing span is small, only 1.5 about m

Embodiment Construction

[0035] refer to Figure 1 to Figure 5 As shown, the self-propelled tobacco seedling leaf cutting equipment 1 of the present invention includes a frame assembly 2 and a leaf cutting trolley arranged on the frame assembly. The frame assembly 2 includes vertical support frames at both ends and a pair of frame beams ; It also includes a control system that can realize the regulation and control of the operation of various electrical components, which is centrally placed in a control cabinet 7 and can be fixed on the frame 2 through brackets, bolts and nuts respectively.

[0036]The innovation of the present invention is: a pair of mutually parallel leaf cutter moving tracks 8 are fixed at both ends of the greenhouse tobacco seedling culture liquid pool, see Figure 6 As shown, the moving track 8 of the leaf cutter can be fixed at both ends of the greenhouse tobacco seedling culture liquid pool by welding. Design a frame assembly, a pair of driving wheels 11 and a pair of driven w...

Abstract

The invention discloses self-propelled tobacco seedling leaf cutting equipment which comprises a frame assembly, a leaf cutting trolley and a control system, wherein a pair of leaf cutting machine moving tracks is fixed at two ends of each culture fluid pool of greenhouse tobacco seedlings; a pair of wheels at the bottom of the frame assembly can advance on the moving tracks; a frame is provided with a lateral moving mechanism assembly which can realize span transfer of the entire leaf cutting equipment; a leaf cutting machine handpiece assembly on the leaf cutting trolley is hung below a frame beam and can advance in a rolling way under the driving action of a driving motor along the beam; and a cable conveying device is arranged. The leaf cutting trolley is driven by the motor to realize transverse stepless variable-speed leaf cutting operation of the leaf cutting equipment, leaf cutting height of the leaf cutting handpiece is controlled by a screw rod and a guide threaded sleeve, and forward-backward, leftward-rightward and upward-downward three-dimensional leaf cutting operation of the leaf cutting equipment above a seed tray is realized; automatic conveying and folding of cables are realized by the cable conveying device assembly; and span transfer of a leaf cutting machine is realized by a lateral moving mechanism, so that a multi-span operation function of one leaf cutting machine is realized.

Description

technical field [0001] The invention belongs to the technical field of agricultural engineering, and in particular relates to a self-propelled leaf cutting device for tobacco seedlings. Background technique [0002] As a key link in floating seedling cultivation technology, leaf cutting can improve the light conditions of tobacco seedlings, promote the growth of rhizomes, make the tobacco seedlings strong and uniform, and play an important role in the process of cultivating high-stem and strong seedlings. In the process of floating seedlings, it is generally necessary to cut the leaves 4-5 times before the seedlings become seedlings. The process of leaf cutting is complicated, there are many procedures, and the possibility of virus transmission is high, which not only increases labor costs, but also increases the probability of germ transmission. Therefore, cutting leaves of tobacco seedlings has become a major difficulty in floating seedling raising technology. In the past...
