Vegetable transplanting machine

Abstract

The invention relates to a vegetable transplanting machine. The vegetable transplanting machine comprises a rowed seedling conveying device, an automatic seedling separating device and a planting device, wherein the rowed seedling conveying device comprises a rear conveying belt, a left baffle and a right baffle, the left baffle comprise a fixed baffle and a movable baffle, and the right baffle and the fixed baffle are fixedly mounted on a base; the movable baffle is driven by a first air cylinder and can be overturned; the automatic seedling separating device comprises a front conveying beltand a parallel connecting rod frame, and a fixed side conveying belt and a movable side conveying belt are arranged on two sides of the front conveying belt; a stirring fork is arranged on a movable block of a parallel connecting rod frame, and the stirring fork and the movable side conveying belt are driven by a second air cylinder; and the first air cylinder and the second air cylinder are synchronously driven by a two-position five-way switch valve, and the planting device is used for driving a bow-shaped rod to drive the switch valve to execute an elastic contact action. The vegetable transplanting machine which can be used for finishing the procedures of ridge surface leveling, seedling conveying, seedling separation, seedling planting and the like once is low in seedling growing requirement, simple in structure and good in stability.

Description

technical field [0001] The invention relates to a vegetable transplanting machine, which belongs to the technical field of agricultural machinery. Background technique [0002] my country is the largest producer and consumer of vegetables in the world. Vegetables are grown mainly in two ways: direct seeding and transplanting. On the one hand, transplanting of seedlings can shorten the vegetable growth cycle, facilitate stubble arrangement, improve land utilization rate, and increase economic income; on the other hand, after transplanting, the root system of crop seedlings is well developed and mature, which makes more than 60% of vegetable varieties in my country currently Planted by seedling transplanting. For a long time, vegetable transplanting operations have been mainly done manually. However, under the background of high investment and high cost in my country's agriculture, the problem of difficult and expensive labor has become increasingly prominent, and the developm...

Problems solved by technology

For a long time, vegetable transplanting operations have been mainly done manually. However, under the background of high investment and high cost in my country's agriculture, the problem of difficult and expensive labor has become increasingly prominent, and the development of mechanized transplanting is urgently needed.

[0003] At present, domestic mechanized transplanting of vegetables mostly adopts semi-automatic transplanting machines, and artificial single-plant seedling picking and seedling feeding are used for seedling cultivation in the plug tray. In order to increase the speed of transplanting, there are also automatic transplanting at home and abroad, such as the Japanese Yanmar PF2R automatic vegetable transplanting machine, which has sold nearly a hundred units in my country in the past five years, but they are basically project demonstrations. , did not form a production application. The reason is that this model has high requirements for seedling cultivation, complex structure, poor stability, difficult maintenance, high cost, and difficult promotion. Therefore, it is urgent to develop fast vegetable transplanting machines with good operation effects.
