The invention relates to the technical field of chemical fertilizer production, and especially relates to a trolley for fertilizer production and transportation. The trolley Comprises a bottom plate,sliding grooves are formed in the left side, close to the front face and the back face, in the bottom plate, a clamping hole is formed in the right side of the bottom surface of each sliding groove, afirst waterproof cloth is fixedly connected to the bottoms of the clamping holes, supporting blocks are fixedly connected to the top of the first waterproof cloth, a balance weight ball is slidably connected to the interior of each sliding groove and is located at the top of the corresponding supporting block, a counterbore is formed in the left side of the bottom face of each sliding groove, anda reset spring is fixedly connected to the interior of the counterbore. By means of free rolling of the balance weight balls in the sliding grooves and cooperation with a transmission column and a friction plate on the left side, when the trolley moves on the downhill ground, the balance weight balls roll to the left side to press the transmission column downwards to make the friction plate makecontact with wheels, so the trolley can automatically decelerate, and workers can better conduct transportation work when the trolley goes downhill.
本发明涉及化肥生产技术领域,具体揭示了一种化肥生产运输用手推车,包括底板,所述底板内部左侧靠近正面和背面均开设有滑槽,所述滑槽底面的右侧开设有卡孔,所述卡孔的底部固定连接有第一防水布,所述第一防水布的顶部固定连接有托块,所述滑槽的内部滑动连接有配重滚珠,所述配重滚珠位于托块的顶部,所述滑槽底面的左侧开设有沉头孔,所述沉头孔的内部固定连接有复位弹簧;本发明通过配重滚珠在滑槽中的自由滚动,配合左侧的传动柱和摩擦片,可以让小推车在下坡的地面运动时,配重滚珠滚到左侧压住传动柱向下使摩擦片接触车轮,可以让小推车自动进行减速,工人能在小推车下坡时更好地进行运输工作。
