Abstract
The invention relates to a seedling culture bed, in particular to a pressure-driven lift seedling culture bed, belonging to the technical field of seedling culture.Traditionally, an overhead seedling culture bed is employed for seedling culture, which is not conducive to root generation of the seedlings at the early stage but also consumes a lot of water; the seedlings can also be cultured on a ground seedling culture bed; although the practice is conducive to root generation of the seedlings and water conservation, the problems such as mutual interspersing of root systems, root segment mildew and the like are easily caused. Multiple lifters of the seedling culture bed are arranged at the same underground horizontal plane, piston connecting rods of the lifers serve as support columns of a seedling culture bed frame and are connected with connecting cylinders of the seedling culture bed frame to form the pressure-driven lift seedling culture bed. Water or gas is used as the transmission stress of the lifters; in particular, water from a nursery garden water supply system is used as the transmission stress to lift the seedling culture bed, thus simplifying the fabrication process of the pressure-driven lift seedling culture bed. by using the seedling culture bed in the invention, the problem that the existing seedling culture bed is confined in application in the process of culturing seedlings is solved, thus being applicable to different seedlings and enabling seedling culture at different seedling culture time periods.
Description
Technical field:
The invention belongs to the seedling growing process field, relate to a kind of bed of growing seedlings, relate in particular to a kind of pressure lifting formula bed of growing seedlings.
Background technology:
At present, the modern container nursery technology of China, by the past traditional with the grow seedlings pattern of earth as seedling medium and small size, progressively grow seedlings and intensification, the transformation of scale breeding direction to light ground mass.Owing to excavate a large amount of earth as seedling medium, caused the destruction serious, and, caused the afforestation difficulty of going up a hill because earth matrix is heavier to environment, increased the cost of transportation of nursery stock simultaneously.In order to solve the problem of above-mentioned existence, adopt light ground mass to substitute earth has become current container nursery as container nursery matrix development trend.Drainage is too fast, water retention property is poor but the employing light ground mass exists in seedling raising process as container nursery matrix, be unfavorable for problems such as seedling root growth, and guaranteeing the moisture content that seedling growth is required by prolonging spray time or increasing the water spray number of times, the increase of water consumption must cause the rising of seedling cost.If container for plant growth is directly put on the ground, contact with the direct of ground by container, keep the humidity on ground to increase container humidity to reduce water consumption, though such seedling-cultivating method can solve the excessive problem of water consumption.But along with the growth of nursery stock, the nursery stock root system can mutually intert and influences the quality of nursery stock between container.In addition container seedling is put on the ground and cultivate, run into spring during continuous rainy weather, be easy to occur the mildew of nursery stock root blackout, going mouldy of nursery stock can infect other nursery stock, can cause the large-area death of nursery stock when serious.Container seedling is placed on the overhead bed of growing seedlings grows seedlings, utilize flowing seedling root being carried out " air is cut root " of air, solved the phenomenon that root system interts mutually between nursery stock, also can solve rainy weather and cause the mouldy problem of the root system that causes because of humidity is excessive.But the appearance of rainy weather is uncertain, when nursery stock be placed in the overhead bed a period of time of growing seedlings eliminate go mouldy after, in order to preserve moisture and using water wisely, again nursery stock is moved up on the ground, consumed a large amount of labours.Utilize to consume that a large amount of labours cuts root at air, preserve moisture water saving and elimination are gone mouldy, and each link is changed, and finally can cause the increase of seedling cost.
In sum: utilize the overhead system bed of growing seedlings to carry out the nursery stock cultivation, be unfavorable for taking root of nursery stock early stage, and water consumption is excessive.Put on the ground and grow seedlings, take root, occur the problem that seedling root interts mutually and root goes mouldy easily though help nursery stock.How to address the above problem, reduce seedling cost, guarantee that the quality of nursery stock has become the key point of scale breeding.Thereby, developed the pressure lifting formula bed of growing seedlings.
Summary of the invention:
Purpose of the present invention: in order to solve the variety of issue that an above-mentioned kind of growing seedlings occurs in actual seedling raising process, it is few to aim to provide easy to operate in a kind of seedling raising process, saving of work and time, using water wisely, power consumption, for different nursery stocks, the season of growing seedlings, different seedling raise periods different, the pressure lifting formula that can adjust the bed height of the growing seedlings bed of growing seedlings.
Technical method of the present invention is:
1, adopt a plurality of lifters to be arranged on underground same horizontal plane, the piston rod of lifter is as the support column of seedling raising bedstead, and is connected with the connecting cylinder of seedling raising bedstead, the decomposition pressure elevation (over-and-under) type bed of growing seedlings.
2, utilize water or gas transmission pressure source as lifter, by force pump or air compressor, basin, pressure main pipe, pressure be in charge of, inlet valve, outlet valve and lifter connect into pressure system.
The present invention is achieved in that
A kind of pressure lifting formula bed of growing seedlings, comprise seedling raising bedstead, it is characterized in that: this bed of growing seedlings is made up of seedling raising bedstead, lifter and pressure system, described pressure system provides the mechanism that pressure source is given lifter, it is underground that lifter adopts piston cylinder operator, lifter to bury to adorn, and fixes with concrete, lifter is provided with piston rod, and piston rod is as the support column of seedling raising bedstead.
Above-described seedling raising bedstead is made up of bedstead housing, seedling pan arrest bar, bedstead horizontal stripe and connecting cylinder; Seedling raising bedstead adopts Metal Material Welding, the bedstead housing respectively with bedstead horizontal stripe and the welding of seedling pan arrest bar, be provided with connecting cylinder below the bedstead horizontal stripe, seedling raising bedstead is provided with one or more layers.
Above-described pressure system is in charge of by pressure main pipe, inlet valve, force pump or air compressor, basin, outlet valve, pressure and accessory is formed; Pressure main pipe is provided with between two row's lifters, and by Connection Element pressure is in charge of with each lifter and is connected, and force pump or air compressor are connected with inlet valve.
Above-described pressure source adopts running water or compressed air.
Above-described lifter is by cylinder barrel, piston, piston rod, horizontal location sleeve, buffer spring, and cylinder cap and cylinder head fixing stud are formed; The piston two ends are provided with O shape rubber seal groove respectively one, O shape rubber seal is installed on the O shape rubber seal groove, lubricating oil groove is set one between two seal grooves, the piston center is provided with a piston rod hole, piston rod and piston are interference fit, be with the horizontal location sleeve on the piston rod, the freely regulated height of 0-1000mm energy is set, buffer spring is equipped with in horizontal location sleeve top; Cylinder cap endoporus and piston rod are matched in clearance, the cylinder cap endoporus is provided with the felt seal groove, and the felt sealing ring is installed in the felt seal groove, and cylinder cap external diameter and internal diameter of cylinder are matched in clearance, and corresponding several bolts hole that is provided with cylinder barrel, cylinder cap and cylinder barrel 24 use cylinder head fixing stud to fix.
