[0003] Some existing mechanism sand transport devices, such as the device disclosed in CN 222247234 U, meet the transportation needs to some extent. Users can use the handle to push the sand cart to realize displacement transportation, and the limiting structure provided on the sand cart can limit the displacement on the plane and perform emergency braking when the user goes uphill, which protects the safety of workers to some extent. In addition, the design of cleaning plate and cleaning block can assist in removing foot mud and sand, enhancing the practicality of the device.

Workers may not be able to quickly step on the limiting block due to delayed reaction or inconvenience, resulting in loss of control of the transport device and causing safety accidents, which seriously threatens the safety of workers and may cause damage to production equipment and surrounding environment. Therefore, it is urgent to develop a new type of transport device for mechanism sand production with active emergency braking function. UTILITY MODEL CONTENTS
