Description

Device for transplanting mature shrubs in arid and semi-arid regions

Technical Field

The utility model relates to a transplanting device, which is used for a device for transplanting mature shrubs in arid and semi-arid regions.

Background

With the improvement of governments in various regions on ecological environment, the recovery of vegetation in arid and semi-arid regions is continuously increased by various departments. In the early days, arbor trees are generally used for greening arid and semiarid regions, but the implementation cost and the maintenance cost are found to be too high, and the arbor trees are not easy to survive. The shrub is a transition stage between herbage and arbor, and has the characteristics of drought resistance, low cost, low maintenance, high survival rate and the like. In arid and semiarid regions with herbs as main vegetation, shrubs suitable for growing in the regions are preferentially planted, so that the water content in the soil of the regions can be greatly improved, and good soil conditions are created for planting trees in the next step, and the method also conforms to the law of natural succession. However, direct sowing of shrub seeds or transplanting of shrub seedlings is inefficient and requires extensive management at the early stage, similar to the problems encountered with transplanting trees. If mature shrubs are transplanted from a cultivation base in a large batch, the shrubs can be quickly established in a target area, the greening efficiency is improved, and the management difficulty is reduced. However, mature shrubs are thick in root systems and difficult to transplant, and the root systems of the shrubs can be damaged in a large area by an excavating tool in the excavating process. In addition, the shrubs after transplantation may die without adapting to the local environment. In order to solve the problem of transplanting mature shrubs, a device capable of conveniently transplanting mature shrubs is designed. When the shrubs are transplanted, the complete root systems can be well reserved. After the transplantation is finished, the mature shrubs show strong adaptability to the transplantation. The method has important significance for accelerating the ecological restoration of arid and semiarid regions.

Preferably, the thickness of the green manure paved at the bottom is more than two centimeters, and the paving range of the green manure is more than the range of the long teeth; the thickness of the green manure wrapped on the four walls is two centimeters.

The main functions of the inner ceramic layer are as follows: 1. ensuring the good development of shrubs before transplantation. 2. Protecting most of the main root system. 3. The transportation is convenient. 4. The survival rate after transplanting is improved. The utility model discloses an interior pottery layer is fired by river bottom earth, thoroughly decomposed fertilizer and cobblestone etc. and stereotypes, and its shape is similar to square flowerpot, and there is great hole bottom. The river bottom soil is acid soil, can neutralize alkaline soil from arid and semi-arid regions on the inner side and the outer side of the inner ceramic layer, meanwhile, a large amount of humus in the river bottom soil can slowly provide nutrients for the soil and can improve the soil environment on the inner side of the inner ceramic layer, and the adhesion of the humus can improve the structural strength of the inner ceramic layer. The decomposed organic fertilizer is similar to humus in soil at the river bottom, and can provide nutrients and reinforce the inner ceramic layer. Cobblestones are the 'endoskeleton' of the inner ceramic layer, the cobblestones have the function of mutual supporting, and gaps formed among the cobblestones can provide penetrating spaces for the root systems of mature shrubs. Although the walls of the inner ceramic layer can allow lateral roots to pass through, the expansion capability of the inner ceramic layer towards the periphery is weakened, and the space left by the big hole at the bottom of the inner ceramic layer can promote the growth of the main root system of shrubs. Meanwhile, water stored in the inner ceramic layer can also flow to the big hole at the bottom, so that the growth of the main root system is promoted. This is to reduce the damage caused by the transplanting process and to improve the survival rate of the mature shrubs after the transplanting. The appearance of the inner ceramic layer is square, and the inner ceramic layer and mature shrubs can be regularly placed in a transport tool after being integrally taken out, so that gaps formed among the inner ceramic layer and the shrubs are greatly reduced, and damage to the inner ceramic layer caused by shaking in the road is reduced.

The main functions of the framework layer are as follows: 1. and the integrity of the inner ceramic layer and the soil and the root system at the inner side of the inner ceramic layer is promoted. 2. The grid can fix soil and improve water gathering capacity 3, and mature shrubs can be conveniently moved out of the soil. The main column is a main component of the framework layer, a rotating shaft is hidden in the main column, and the rotating shaft can be connected with the pawl teeth and the rotating pull rod. The outer part of the main column can be connected with the partition plate, the baffle plate, the bearing disc and the chassis; the chassis is connected with the main root protection net; the partition board is positioned at the upper part of the framework layer, the board is higher than the unearthed layer, the influence of desertification on the soil surface can be weakened, and the partition board and other parts of the framework layer play a role in soil stabilization. Meanwhile, the concave pit surrounded by the water-collecting layer has the function of water collection. The main column, the partition plate, the baffle plate and the chassis are equivalent to an 'external skeleton' of the inner ceramic layer. When the inner ceramic layer is permeated by rainwater, the supporting function of the 'inner skeleton' and the protecting function of the 'outer skeleton' of the inner ceramic layer can ensure that the structure of the inner ceramic layer is relatively intact. Meanwhile, the integrity of the inner ceramic layer and the soil and root system at the inner side of the inner ceramic layer is promoted by the action of the inner ceramic layer and the inner ceramic layer, so that the mature shrubs can be transplanted and transported conveniently in the future.

The main column, the claw teeth, the bearing disc and the rotary pull rod form a moving and taking function part. The claw teeth are divided into two long teeth and one short tooth, the two structures are triangular pyramid shapes, the conical planes of the two long teeth face downwards, and the three edges face towards the left side, the right side and the top of the three short teeth respectively. The cone plane faces downwards to support the whole device smoothly, and the three edges face downwards to form a cutting surface during rotation. The main task of the two long teeth is to break up the surrounding soil and provide support, and the main task of the short teeth is to provide support, which is less able to break up the surrounding soil. The included angle of the two long teeth is less than 90 degrees, and the rotating range of the two long teeth cannot influence the main root protection net at the lower part of the chassis. The rotary connecting rod which is connected in a rotating way can lead the two long teeth of the claw teeth to break the soil around the bottom of the framework layer. The rotating connecting rod can also replace the rotating work of the rotating connecting rod by an adaptive motor, thereby further reducing the manpower. The upper part of the rotary connecting rod is provided with a triangular mark which can prompt the orientation of the long teeth. When mature shrubs are moved out of the earth, the long teeth are hidden under the chassis according to the prompt of the triangular mark, and only the short teeth are exposed on the periphery of the chassis, so that the resistance in moving is greatly reduced. The chassis adopts a triangular nesting structure, and the middle part of the chassis is provided with a larger space which can be matched with a big hole at the bottom of the inner ceramic layer and the main root protection net. The main root protection net is a barrel-shaped net, the upper part of the main root protection net is wide, the lower part of the main root protection net is narrow, and the lower part of the main root protection net is in a recovery state. The wide mesh does not affect the development of the main root system. When mature shrubs are transplanted, the soil bound inside the main root protection net automatically protects the main root system, so that the damage of the transplanted mature shrubs to the main root system is obviously reduced. The bearing plate is a stressed part which is lifted upwards when the shrubs are moved out of the soil, and the firmness of the bearing plate is ensured when the materials are selected. The main function of the functional part is to break the cross section of the root system bottom. In the prior art, when the lateral root system is manually moved, the lateral root system can be touched by digging the transverse section by expanding the transverse section towards the periphery. However, this is a significant waste of manpower and can also damage the lateral root system. If the transverse cutting method of the utility model is adopted, the excavation range can be reduced, and the moving resistance when the shrub is moved out of the soil can be weakened.

The main functions of the green fertilizer layer are as follows: 1. the resistance when the mature shrub is moved out of the soil is weakened. 2. Improving the soil environment around the green manure layer. The green manure layer of the utility model is divided into a bottom part and four wall parts. The thickness of the green manure layer at the bottom is more than two centimeters, and the laying range of the green manure layer is more than the range which can be reached by the long teeth. The four-wall part means that green manure with the thickness of two centimeters is wrapped outside the framework layer and is wound and fixed by thin lines. The green manure can be leguminous forage, and when the green manure layer is buried in soil, the green manure layer can be slowly decomposed and utilized by soil microorganisms to form relatively rich organic matters. The organic matters further improve the soil structure and form a large amount of larger soil aggregates, so that the soil around the green manure becomes looser. The existence of the green manure layer can make the resistance of the whole operation become smaller in the whole process of completing the bottom transection and the shrub removal of the removing function part.

The utility model discloses the space that the device stayed and specification size need just step into the required root system home range size of maturity stage and set for from the seedling stage according to the bush of selecting. That is, after the selected shrubs are planted in the mature period for a period of time, when the lateral root system starts to penetrate out of the inner pottery layer and the main root system starts to penetrate out of the bottom of the main root protection net, the optimal time for transplanting the mature shrubs out of the soil is reached, and the selected shrubs are planted in the mature period, so that the metabolism is vigorous, and the survival rate after transplantation is high.

The time point for moving the mature shrubs is based on the condition that the lateral roots of a few selected shrubs extend out of the inner pottery layer and the main root just penetrates out of the bottom of the main root protection net. In normal times, the development characteristics of the overground part of the shrub at the time point of the moving are taken care of. Meanwhile, the time length of the whole period from the beginning of seedling raising to the time point of transferring should be kept in mind. This helps to judge whether or not mature shrubs can be removed without observation by digging them. This also provides for future mass transplanting of the selected mature shrubs.

The utility model discloses a device is integrated configuration, is the problem that meets in the physical and chemical properties of application soil and the growth characteristic of plant solve whole cultivation and transplanting flow. It has the characteristics of environmental protection, low cost, low manpower and the like. Meanwhile, the device has multiple functions of shrub cultivation, convenient mature shrub transplanting and the like, and the adaptability of the mature shrubs is improved after the mature shrubs are transplanted. The utility model discloses also provide probably for transplanting the standardized volume production of ripe bush this device. Furthermore, the device is also suitable for transplanting small trees.

It plays a role in protecting the root system when the mature shrubs are transplanted. The damage to mature shrubs caused by shaking of the vehicle body can be weakened during transportation. Which can improve the surrounding environment and enhance the adaptability of transplanting mature shrubs after transplantation. 2. The moving function part of the framework layer can transversely cut the soil at the bottom of the root system, so that the manual excavation is reduced to a great extent. 3. The claw teeth of the framework layer moving functional part can skillfully relieve the moving resistance brought by the long teeth while breaking the soil. 4. The partition board of the framework layer has the functions of preventing sand and gathering water. 5. The green manure can improve the soil environment and weaken the transfer resistance when mature shrubs are transferred.
