Transmission device of heavy-duty chain plate machine

Abstract

The invention discloses a transmission device of a heavy-duty chain plate machine, which comprises a ratchet, a swing arm, a first connecting rod, a disk and a second connecting rod, wherein the swing arm is arranged on the ratchet, the first connecting rod is arranged at the lower end of the swing arm, the second connecting rod is arranged at the lower part of the disk, and the first and the second connecting rods are connected through a loop chain; and a spring is connected at the upper end of the swing arm, and the other end of the spring is fixed. In the transmission device of the heavy-duty chain plate machine, the swing arm is pushed to make a reciprocating motion under the action of the loop chain and the spring, and the loop chain has high strength and is not liable to be damaged. The invention overcomes the problem in the prior art that the connecting rods of the transmission device of the heavy-duty chain plate machine is liable to be broken, increases the operating continuity and stability of the heavy-duty chain plate machine and increases the work efficiency of the heavy-duty chain plate machine. Besides, the eccentric wheel is replaced by the loop chain and the spring, so as to decrease the number of parts of the heavy-duty chain plate machine and provide convenience for maintenance.

Description

technical field [0001] The invention relates to a heavy-duty chain conveyor, in particular to a transmission device of the heavy-duty chain conveyor. Background technique [0002] The transmission device of the existing heavy-duty chain plate machine, as attached figure 1 As shown, it includes ratchet 1, swing arm 2, disk 3, eccentric wheel 4 and connecting rod 5, swing arm 2 is arranged on ratchet 1, eccentric wheel 4 is arranged on disk 3, the lower end of ratchet 1 is connected with the eccentric wheel 4 The lower ends are connected by connecting rod 5. When working, the eccentric wheel 4 rotates and drives the swing arm 2 to reciprocate through the connecting rod 5 . However, as the volume of items transported by the heavy-duty chain conveyor is increasing, the load of the heavy-duty chain conveyor is also increasing, and the connecting rod 6 is frequently broken, which increases the number of shutdowns and seriously affects the transportation of the heavy-duty chain c...
