Description

DESCRIPTION Pear seedling cultivation tank with adjustable space size

TECHNICAL FIELD The present invention belongs to the technical field of agricultural pear plane cultivation device, more specifically, it relates to a kind of pear seedling cultivation tank with adjustable space size.

BACKGROUND Pear seedlings for agricultural planting need to be cultivated in special growth environment. With general seedling methods, such as sowing, cutting, grafting and other methods to cultivate tree seedlings, the initial density of small seedlings is larger, after emergence, with the continuous growth of seedlings, the individual seedlings gradually increase, seedlings will restrict each other, compete for water, fertilizer, light, air, which seriously restricts the growth and development of seedlings. Therefore, it is necessary to expand the row spacing of seedlings, which can be achieved by interplanting and transplanting. However, intermediate seedlings will waste seedlings, and the remaining seedlings cannot cut their roots to promote their development. Therefore, the transplanting method is often used to expand the row spacing of seedlings, which not only expands the living space, makes the root fully stretch, further expands the tree shape, endows the leaves with sufficient sunlight, enhances the physiological activities such as photosynthesis and respiration of tree seedlings, provides a good environment for the healthy growth of seedlings, but also reduces the breeding of pests and diseases, and facilitates the daily management of fertilization, irrigation, pruning and grafting.

For example, the application number is CN201710856817.2. The invention discloses a garden sapling cultivation device, which comprises a supporting plate, a rotating device, a circular plate, a second bearing seat, a second rotating shaft and the like. A rotating device is arranged between the left and right support plates, and the rotating parts of the rotating device are connected with two circular plates which are located between the left and right support plates and are symmetrically arranged, and the eccentric positions of the circular plates are embedded with second bearing seats.

Based on the search of the above patents and combined with the structure in the prior art, it 1s found that when the cultivation tank is used, the cultivation tank is inconvenient to move, and the corresponding treatment mode can not be made in time according to the outdoor abrupt weather state, which is easily affected by severe weather. During the seedling growth process, the density of seedlings is high, and with the continuous growth of seedlings after emergence, the root system of seedlings gradually develops, which makes the original narrow seedling cultivation tank unable to bear the growth space of seedling root system. The individual size of seedlings is gradually increasing, which is not convenient to expand the row spacing of seedlings. The seedlings influence each other and compete for water, fertilizer, light and air, which seriously restricts the growth and development of seedlings.

SUMMARY In order to solve the above technical problems, the invention provides a pear seedling cultivation tank with adjustable space size, which solves the problems that when the cultivation tank is used, the cultivation tank is inconvenient to move, the corresponding treatment mode can not be made in time according to the outdoor abrupt weather state, and it is easy to be affected by bad weather, the density of seedlings is higher during the seedling growth process, and the root system of seedlings is gradually developed with the continuous growth of seedlings after emergence. Therefore, the original narrow space seedling cultivation tank can not bear the growth space of the seedling root system, and the individual seedlings gradually increase, which is inconvenient to expand the row spacing of seedlings. The seedlings influence each other and compete for water, fertilizer, light and air, which seriously restricts the growth and development of seedlings.

The purpose and efficacy of the pear seedling cultivation tank with adjustable space size of the invention are achieved by the following specific technical means: The pear seedling cultivation tank with adjustable space size, including a tank body, a vertical beam, a crossbeam, a water supply pipe, a universal wheel, a water distribution plate, and a vertical shaft. The tank body comprises a left half tank and a right half tank; The left half tank also includes the left side plate and the left outer edge. The left side plate is processed on both sides of the left half tank, and the left outer edge is processed on the right side of the left half tank. The right half tank also comprises a right plate, a guide rod, a right outer edge and a seepage hole; The bottom of the right half tank has a seepage hole,

and the left side of the right half tank has a right outer edge. The two sides of the right half tank have a right plate, and the left surface of the right plate is fixed and connected with two guide rods. The left half tank is connected to the right half tank, and the two sides of the spring are fixed on the relative surface of the left plate and the right plate respectively. the vertical shaft is fixedly connected below the tank body; the wheel frame of the universal wheel is fixedly connected to the lower end of the vertical shaft; the two ends and the middle of the vertical beam are rotated and connected with a vertical shaft respectively; the two ends and the middle of the beam are also rotationally connected to the vertical axis; The water supply pipe is fixedly connected to one side of the tank body, and the water supply pipe is connected to three tank bodies; The distributor is located at the inner bottom of the tank body, and the distributor is fixedly connected to the water supply pipe.

Further, the left half tank is a vertically cut half square tank, and two round holes are processed on the left side plate, and the left outer edge is a structure in which the inner surface of the left half tank extends to the right.

Preferably, the right half tank is also a vertically cut half square tank, and the guide rod is movably connected in a round hole on the left side plate, and the diameter of the left circular stopper of the guide rod is larger than that of the round hole on the left side plate, the right outer edge is a structure in which the outer surface of the right half tank extends leftwards, and the spring is located outside the guide rod.

Furthermore, the vertical beam 1s a square rod, and two sides of the vertical beam are respectively provided with a circular through hole, and the middle of the vertical beam 1s also provided with a circular through hole.

Additionally, the beam is also a square rod, and two sides of the beam are respectively provided with a circular through hole, and the middle of the beam is also provided with a circular through hole.

Further, the water supply pipe comprises a water inlet, both ends of the water supply pipe are sealed, the middle of the water supply pipe is connected with a water inlet with an upward opening, and the water supply pipe penetrates the outer wall of the tank body and is communicated with the inside of the joint of the water distribution tray.

Furthermore, the water dividing plate comprises an overflow hole, a round tank and supporting legs, and the water dividing plate is a disc with a disc-shaped round tank in the middle.

In addition, seven circular through-hole overflow holes are uniformly distributed above the water distribution tray, and the supporting legs are fixedly connected to the lower surface of the water distribution tray at three points.

Compared with the prior art, the invention has the following beneficial effects: The left half tank and the right half tank of this structure are matched and combined into a tank body of the cultivation tank, which is connected by springs and guide rods, and the edges of the left half tank and the right half tank are both processed with outer edges.

Under normal conditions, the left outer edge and the right outer edge are acted by spring force, and the volume of the tank body 1s normal. With the growth of seedlings, the root system of seedlings gradually develops. Therefore, the original narrow sapling cultivation trough can not bear the growth space of sapling roots, and the individual seedlings gradually increase. At this time, the gradually developed root growth and expansion strength will be greater than the spring force, so that the left half trough and the right half trough on both sides will expand to both sides and increase the internal volume of the cultivation trough, thus avoiding the serious restriction of the growth and development of seedlings due to the constant volume of the cultivation trough during the growth of pear seedlings.

It can be seen from the cooperation between the crossbeam and the vertical beam under the tank body of the cultivation tank that a hinged structure is formed between the crossbeam and the vertical beam, and the intersection of the crossbeam and the vertical beam is rotatably connected to the vertical shaft under the cultivation tank. It can be seen from the structure of the crossbeam and the vertical beam that a parallelogram mechanism is formed. When the cultivation tanks on the front row of crossbeams approach to the middle, the rear row of cultivation tanks also approach to the middle row at the same time, realizing the function of changing the density of pear seedlings. It can be convenient to expand the row spacing of seedlings when the seedlings gradually increase, avoiding the problems that the seedlings influence each other, compete for light, air, etc., and seriously restrict the growth and development of seedlings. Furthermore, the universal wheel is installed below the vertical axis, which can change the position of seedlings in time with the change of outdoor weather, reduce the damage of seedlings to severe weather environment and improve the survival rate.

With the cooperation of the water supply pipe and the water distribution plate, the appropriate amount of water is provided on the water inlet. The inner wall of the water supply pipe connects the inner space of the water distribution plate, and the water supply pipe can evenly distribute the water on each water distribution plate. When the water supply continues, the water overflows from the overflow hole above the water distribution plate, so that the bottom of the soil in the cultivation tank is exposed to more water. This can form a wet and dry state of the soil in the cultivation tank. In contrast to the effect of the traditional soil surface watering method, the wet and dry soil structure can promote the root of the pear seedling to extend downward to obtain more water, so that the root of the pear seedling is more firmly rooted in the soil, improve the resistance of the pear seedling to external forces, and further improve the stability of the pear seedling.

Example: As shown in Figure 1 to Figure 9: The invention provides a pear seedling cultivation tank with adjustable space size, which comprises a tank body 1, vertical beams 2, cross beams 3, water supply pipes 4, universal wheels 5, water distribution trays 6 and vertical shafts 7, wherein the tank body 1 comprises a left half tank 101 and a right half tank 102; The left half tank 101 also includes a left side plate 103 and a left outer edge 107, both sides of which are integrally processed with the left side plate 103 and the right side of which is integrally processed with the left outer edge 107. The right half tank 102 also includes a right side plate 104, a guide rod 105, a right outer edge 108 and a water seepage hole 109. The bottom surface of the right half-tank 102 is provided with a water seepage hole 109, and the left side of the right half-tank 102 is integrally processed with a right outer edge 108, and both sides of the right half-tank 102 are integrally processed with a right side plate 104, and the left side surface of the right side plate 104 is fixedly connected with two guide rods 105. The left half tank 101 is movably connected to the right half tank 102, and both sides of the spring 106 are respectively fixedly connected to the opposite surfaces of the left side plate 103 and the right side plate 104.

The vertical shaft 7 is fixedly connected below the tank body 1; The wheel frame of the universal wheel 5 is fixedly connected with the lower end of the vertical shaft 7; Two ends and the middle of the vertical beam 2 are respectively rotatably connected with a vertical shaft 7; The two ends and the middle of the cross beam 3 are also respectively rotatably connected to the vertical shaft 7; A water supply pipe 4 is fixedly connected to one side in the tank body 1, and the water supply pipe 4 is connected with three tank bodies 1; The water distribution tray 6 is located at the bottom inside the tank body 1 and is fixedly connected to the water supply pipe 4. The water supply pipe 4 includes a water inlet 401, both ends of which are sealed, and the middle of the water supply pipe 4 is connected with the water inlet 401 with an upward opening. The water supply pipe 4 penetrates the outer wall of the tank body 1 and communicates with the junction of the water distribution tray

6. The water supply pipe 4 with a sub-structure is shown in Figure 8. The inner pipe body of the water supply pipe 4 is connected with a round tank 602 inside the water distribution tray 6, which can convey water to the water distribution tray 6 Seven circular through-hole overflow holes 601 are evenly distributed above the water distribution tray 6, and the supporting legs 603 are fixedly connected to the lower surface of the water distribution tray 6 in three places. When water is continuously supplied, water overflows from the overflow holes 601 above the water distribution tray 6, so that the bottom of the soil in the cultivation tank comes into contact with more water, which can form a wet and dry state of the soil in the cultivation tank, which is just opposite to the wet and dry effect formed by the traditional soil surface watering method. The wet and dry soil structure can promote the root system of pear seedlings to extend downward to obtain more water, make the root system of pear seedlings take root in the soil more firmly, improve the resistance of pear seedlings to external forces, and further improve the stability of pear seedlings.

Among them, the left half tank 101 is a half square tank which is vertically cut, and there are two circular holes on the left plate 103. The left outer edge 107 is the inner surface of the left half tank 101 extending to the right. The left half tank 101 of the secondary structure is shown in Figure 5. The right half tank 102 is also a half square tank which is vertically cut, and the guide rod 105 is connected to the circular hole on the left plate 103. The diameter of the left circular head of the guide rod 105 is larger than that of the circular hole on the left plate 103. The length of the guide rod 105 limits the expansion range of the tank 1. The right outer edge 108 is the outer surface of the right half tank 102 extending to the left. The spring 106 is located outside the guide rod 105. The left half tank 101 of the secondary structure 1s shown in Figure 4. The left half tank 101 cooperates with the right half tank 102.

The vertical beam 2 1s a square rod with a circular through hole on both sides and a circular through hole in the middle. The cross beam 3 is also a square rod with a circular through hole on both sides and a circular through hole in the middle. The sub-structure of the vertical beam 2 is shown in Figure 7, and the structures of the cross beam 3 and the vertical beam 2 can be seen to form a parallelogram mechanism. When the cultivation tanks on the front row of crossbeams 3 are close to the middle, the rear row of cultivation tanks are close to the middle row at the same time, so as to realize the function of changing the density of pear seedlings. It is convenient to expand the row spacing of seedlings when the seedlings gradually increase, avoiding the problems that the seedlings influence each other, compete for light, air, etc., which seriously restrict the growth and development of seedlings.

When in use: firstly, pear seedlings are cultivated in the tank body 1. When watering, water is added into the water inlet 401, and the water supply pipe 4 is connected with the water distribution tray 6, so that the water overflows from the overflow hole 601 above the water distribution tray 6, so that the bottom of the soil in the cultivation tank comes into contact with more water, thus forming a wet and dry state of the soil in the cultivation tank, which is just opposite to the wet and dry effect of the traditional soil surface watering method. The wet and dry soil structure can promote the root system of pear seedlings to extend downward to obtain more water, so that the root system of pear seedlings can be firmly rooted in the soil, improve the resistance to external forces and further improve the stability of pear seedlings.

With the growth of seedlings, the root system of seedlings gradually develops, which makes the original narrow seedling cultivation tank unable to bear the growth space of seedling roots.

At this time, the gradually developed root system growth and expansion will be greater than the force of spring 106. Expanding the left half tank 101 and the right half tank 102 on both sides to both sides can increase the internal volume of the cultivation tank, which prevents the growth and development of seedlings from being seriously restricted by the constant volume of the cultivation tank body 1 during the growth of pear seedlings.

At the same time, by expanding the angle between the cross beam 3 and the vertical beam 2, it can be seen that an articulated structure is formed between the cross beam 3 and the vertical beam 2, and the intersection of the two is rotatably connected to the vertical shaft 7 under the cultivation tank.

A parallelogram mechanism is formed.

When the cultivation tanks on the front row of crossbeams 3 are far away from the middle row, the rear row of cultivation tanks are also far away from the middle row, so as to realize the function of changing the density of pear seedlings.

It is convenient to expand the row spacing of seedlings when the seedlings gradually increase, avoiding the problems that the seedlings influence each other, compete for light, air, etc., and seriously restrict the growth and development of seedlings.

Furthermore, the universal wheel 5 1s installed below the vertical shaft 7, which can change the position of the saplings in time with the change of outdoor weather, reduce the damage of the saplings to severe weather environment, and improve the survival rate.

The embodiments of the present invention are presented for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed form.

Many modifications and variations will be apparent to those of ordinary skill in the art.. The embodiments were chosen and described in order to better explain the principles and practical applications of the invention, and to enable those of ordinary skill in the art to understand the invention and design various embodiments with various modifications suitable for specific uses.
