The existing box type hatching machine of background technology comprises casing, chamber door, switch board, egg car, egg car guide rail and ventilation, humidifying system and egg-turning mechanism, ventilating system comprises draught fan, air-cooled fan, air door and damper motor, draught fan is positioned at the middle position of casing, air-cooled fan is positioned on the rearing-box plate, air door and damper motor are positioned at the casing top, draught fan provides distinguished and admirable major impetus in the casing, air-cooled fan is carried out forced cooling when the temperature inside the box is too high, damper motor carries out the adjusting of intake by control air door size.Humidifying system generally adopts humidification dish and watershedding sheet combined mechanism, and egg-turning mechanism is positioned at the back bottom of casing, generally adopts gear transmission mode.An outstanding shortcoming of the box type hatching machine of this form is, because the distinguished and admirable more complicated in the casing, turbulent flow and eddy current appear easily, distinguished and admirable direction and size all become with the position, cause the inhomogeneous of temperature and humidity field on the one hand, influence incubation rate, also waste energy simultaneously, improved the hatching cost.In recent years, people had done a lot of improvement to hatch machine, had obtained some effects, but the principle of ventilating system and structure do not have the change of essence.
Summary of the invention the purpose of this invention is to provide a kind of laminar flow ventilation box type hatching machine, and this hatch machine has stabilized uniform temperature and humidity field, and hatching and energy-saving effect are preferably arranged.
The objective of the invention is to be achieved through the following technical solutions: a kind of laminar flow ventilation box type hatching machine, comprise casing, chamber door, switch board, the egg car, egg car guide rail and ventilation, humidification and egg-turning system, ventilating system comprises draught fan, air-cooled fan, air door and damper motor, air door and damper motor are positioned at the casing top, at box house baffle plate is set, casing is divided into ventilation power-section and incubation division two parts, it between baffle plate and the chamber door incubation division, be the ventilation power-section between baffle plate and the boxboard, leave the ventilation air channel between baffle plate and the boxboard, the base plate of incubation division is equipped with egg car guide rail, can lay the egg car, a plurality of its wind directions draught fan parallel with baffle plate is housed, on the top board of casing front portion, be provided with air-cooled fan in the ventilation power-section.
Said partition position has following two kinds at least in the technique scheme:
A, draught fan are contained on the rearing-box plate;
B, draught fan are contained on the top board.
In the technique scheme, the mounting means of draught fan can be vertically to arrange from top to bottom, also can be from preceding then transversely arranged.
Said ventilating system is different with traditional ventilating system in the technique scheme, because draught fan between the boxboard and dividing plate of casing, will form uniform and stable annular airflow, i.e. laminar flow in the casing.This air-flow has the flowing velocity of fixing flow direction and basically identical.If the starting point of the position of draught fan as air-flow, its flow direction is: from starting point, a passage through between baffle plate and the boxboard enters the incubation division, flows back to starting point from another passage between baffle plate and the boxboard then.So move in circles.
On the top board of said casing front portion ventilator cowling is arranged in the technique scheme, air-cooled fan is installed in the top of ventilator cowling, and many forced air cooled tubes are equipped with in the bottom of ventilator cowling, has a plurality of apertures on the forced air cooled tube.She Ji air cooling system like this, cold wind is more mildly blown out from the aperture of forced air cooled tube and case in original air-flow evenly mix, air-cooled dead angle has also been eliminated in the unlikely sudden change that causes temperature.
Said humidifying system is the spraying water pipe that has shower nozzle in the technique scheme, and spraying water pipe is arranged on a side of draught fan, and its water inlet manifold is drawn from boxboard.Injection spray pipe is a kind of advanced person's a humidification apparatus, compares with humidification dish watershedding sheet, and humidification is even, cleans easily, and the purpose of using this equipment is further to improve the stability of humidity.
Said egg-turning mechanism is positioned at baffle plate top in the technique scheme, adopts worm-drive mode or pneumatic egg-turning mode, and the latter is identical with the tunnel hatch machine, uses air cylinder driven, finishes egg-turning and moves.
Advantage of the present invention is: one, fundamentally changed draft type, thereby formed the laminar flow ventilation in casing, more stabilized uniform temperature and humidity field is arranged, created advantage for improving strong young rate; Two, air cooling effect is better; Three, remarkable energy saving effect is arranged.
The invention will be further described below in conjunction with drawings and Examples for embodiment.
Structure such as Fig. 1 of the box type hatching machine that this laminar flow ventilates, shown in Figure 2, it comprises casing (1), chamber door (2), switch board (3), the egg car, egg car guide rail (4) and ventilation, humidification and egg-turning system, ventilating system comprises draught fan (9), air-cooled fan (5), air door (11) and damper motor (12), air door (11) and damper motor (12) are positioned at the top of casing (1), box house is provided with baffle plate (8), casing is divided into front and back two parts, leave the ventilation air channel between baffle plate (8) and the left and right sides boxboard, the front portion of casing is the incubation division, egg car guide rail (4) is housed on the base plate, can lay the egg car, the rear portion of casing is the ventilation power-section, 4 draught fans (9) vertically are housed, the installation site as shown in Figure 3, humidification sparge pipe (13) is installed in the rear side of draught fan (9), its water inlet water pipe is drawn from rearing-box plate, the top of baffle plate (8) is equipped with this egg-turning mechanism (10) of egg-turning mechanism (10) and is adopted the worm-drive mode to drive, on the top board of casing front portion, be provided with square box formula ventilator cowling (6), on the top of ventilator cowling (6) installing hole is arranged, air-cooled fan (5) is housed, the bottom is connected with 3 forced air cooled tubes (7) that vertically are placed in the casing, 4 row's circular holes are arranged around the forced air cooled tube (7), and the cold wind that air-cooled fan (5) blows into can enter casing from these circular holes.Through test, box type hatching machine that this laminar flow ventilates and existing hatch machine relatively, the temperature difference in the casing can be reduced to 0.5 degree by 0.7 original degree, consumed power is reduced to 0.72 kilowatt by 1.5 kilowatts, energy-conservation about 50%, strong young rate improves 1%.
