Description

Technical Field

[0001] The utility model relates to the technical field of pig breeding, in particular to a pig house ventilation device. Background Art

[0002] Ham, also known as "fire meat" and "Lanxun", is a traditional Chinese specialty food. It is the leg of a pickled or smoked animal, such as a pig leg. Pigs, known as shu in ancient times, are omnivorous mammals and one of the five domestic animals. A pig farm is a place dedicated to raising pigs. There are pig houses in the pig farm, which can be divided into breeding pig houses, piglet houses, fattening houses, etc. Most of the current pig houses are surrounded by the ground, two side walls, two gables, and a roof. There is an aisle in the middle of the ground of the pig house, pig pens on both sides of the aisle, windows on the side walls, slatted floors against the side walls of the pig pens, and manure ditches under the slatted floors. In order to make the pigs grow better, the pig house needs to be ventilated. Therefore, an opening is provided on the gable at one end of the pig house, and an exhaust fan is installed to exhaust and ventilate the pig house.

[0003] The angle between the rotating shaft and the fan blades of the existing ventilation device is usually a fixed and unchangeable structure, so that the rotation center of the fan blades cannot be changed. The air inlet and air outlet of the ventilation device are fixed, resulting in the ventilation device only ventilating and sucking air at a fixed position, thereby failing to perform ventilation and exhaust operations in the pig house, reducing the breeding environment of the pigs, directly affecting the subsequent meat quality of the pigs, and reducing the quality of the ham produced.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Two mounting frames 101 are fixed on both sides of the outer shell 1 by bolts. The outer shape of the mounting frame 101 is X-shaped. The rotating support frame 201 passes through the center of the mounting frame 101 and is rotatably connected thereto. There are two mounting frames 101.

One end of the fixed shaft 207 is connected to the mounting frame 101 by bolts, and the fixed shaft 207 and the rotating shaft 204 are meshed. When the support frame 201 rotates, The rotating shaft 204 revolves around the fixed shaft 207, so that the rotating shaft 204 rotates under the drive of the fixed shaft 207, and the output end of the motor 209 is connected to the rotating support frame 201, and the motor 209 drives the rotating support frame 201 to rotate in the shell 1 so that the fixed shaft 207 drives the rotating shaft 204 to rotate. Since there is an angle between the fixed shaft 207 and the rotating shaft 204, the axial inclination angle of the rotating shaft 204 will change when the support frame 201 rotates, so that during the rotation of the rotating shaft 204, the wind direction generated by the rotation of the blades 205 located on the rotating shaft 204 also changes. The rotating support frame 201 is driven to rotate by the motor 209. During the rotation of the rotating support frame 201, the rotating shaft 204 will be driven to rotate by the fixed shaft 207, so that the blades 205 perform exhaust operations, and at the same time, the rotation center of the rotating shaft 204 rotatably arranged on the rotating support frame 201 can be continuously changed, thereby increasing the ventilation and suction area.

When the rotating support frame 201 rotates, the rotation center of the rotating shaft 204 rotatably arranged on the rotating support frame 201 can be continuously changed, thereby increasing the ventilation and suction area. A bevel gear a206 is provided at the end of the rotating shaft 204. A bevel gear b208 is provided at the end of 07, and the bevel gear a206 is meshed with the bevel gear b208, so that when the rotating support frame 201 rotates, the rotating shaft 204 can be driven to revolve around the fixed shaft 207, so that the bevel gear b208 can drive the bevel gear a206 to rotate, thereby driving the rotating shaft 204 to rotate, so that when the motor 209 drives the rotating support frame 201 to rotate around the fixed shaft 207, the rotating shaft 204 rotating in the rotating support frame 201 can be driven by the bevel gear b208 to rotate, thereby increasing the ventilation and suction area.
