Description

Technical Field

[0001] The utility model relates to the field of agricultural breeding, in particular to a music playing trolley for a pig farm. Background Art

[0002] At present, intensive pig farming in pig farms is very common, and it has played a great role in providing people with high-yield pork. However, people have put forward higher requirements on the quality of pork. A large number of experiments have proved that providing beautiful music to growing pigs can increase the yield and quality of pork. Generally, a music player cart is used to play beautiful music for pigs.

[0003] The existing music playing cart has a small playing range. The position of the speakers on the general music cart is fixed. When playing music, it can only be played in one direction. The sound in other directions is lower, resulting in a small playing range. It is necessary to constantly adjust the direction of the cart, which is very troublesome and inconvenient to use. It also does not have a lighting function. Generally, no lighting is installed on the music playing cart. When used at night, it is difficult to see the surrounding environment clearly and it is not convenient to observe the status of the pigs, which affects the user experience and has low practicality. In order to solve the above problems, we propose a music playing cart for pig farms. Utility Model Content
