Grain suckers are usually designed to be mobile and can be easily moved in the fields and can adapt to crops of different types and densities. After the crops are sucked into the machine, they will be collected into a container, which can be a bag full of crops, a collection box or other suitable structure.

[0003] However, the existing grain suction machine trailer has a long pull rod, so that the grain suction machine trailer requires more space when stored or transported, which may limit the user's ability to carry or store the trailer in a narrow space, thereby reducing the portability of the trailer. Utility Model Content
