Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1-5, a thick straw plate breaking saw comprises a motor 1, a tripod 2, a swing arm cylinder 3, a pressing cylinder 4, a guide rod 5, a pressing device 6, a combined chain saw 7, a swing arm 8, a frame 9, a screw 10, a belt 11, a motor belt wheel 12, a pin shaft 13, a chain cover 14, a belt wheel 15, a belt seat bearing 16, a chain wheel shaft 17, a rolling bearing 18, a bearing seat 19, a chain wheel 20, a chain 21, a chain support frame 22 and a bent plate 23.

A thick straw board breaking saw comprises a tripod, wherein the tripod hooks a straw board to follow the straw board through an end hook, and a rack 9 is fixed on the tripod 2 through a screw rod 10 and follows the straw board with the tripod. One end of the pressing cylinder 4 is hinged with the frame 9 and fixed on the frame 9, and the other end is hinged with the pressing device 6; during processing, the compressing cylinder 4 receives a signal and extends out of the piston rod to drive the compressing device 6 to move downwards, so that the straw board is compressed. One end of the swing arm 8 is hinged on the frame 9; two ends of the swing arm cylinder 3 are respectively hinged with the frame 9 and the swing arm 8; the two groups of swing arms 8, the two groups of swing arm cylinders 3, the rack 9 and the combined chain saw 7 form a parallelogram stable structure, and when the combined chain saw works, the swing arm cylinders 3 receive signals to stretch the piston rods, so that the swing arms of the parallelogram group are controlled to move. The motor 1 is fixed on the swing arm 8, the motor 1 receives a signal to start to rotate at a high speed, the main shaft of the motor 1 is provided with a motor belt wheel 12, the motor belt wheel 12 drives a belt wheel 15 arranged on a chain wheel shaft 17 and the chain wheel shaft 17 to rotate through a belt 11 so as to drive the combined chain saw 7 arranged on the chain wheel shaft 17 to rotate at a high speed, meanwhile, the swing arm cylinder 3 receives a signal and extends out of a piston rod, so that the swing arm 8 moves downwards and rightwards, and straw contacted with the combined chain saw 7 flies out from one side, and therefore the function of plate breaking is achieved. A sprocket shaft 17 is mounted on the other end of the oscillating arm 8 via a pedestal bearing 16.

The combined chain saw 7 comprises the following components: the inner ring of the bearing seat 19 is matched with the rolling bearing 18 and is arranged on the chain wheel shaft 17, the outer ring of the rolling bearing 18 is fixed, and the inner ring and the chain wheel shaft 17 rotate together; the chain wheel 20 is arranged on the chain wheel shaft 17 to rotate together; the chain 21 is engaged with the chain wheel 20 and rotates at a high speed along with the chain wheel 20; the bent plate 23 is fixed at two ends of the chain 21 through bolts, and the bent plate 23 is driven to perform plate breaking operation through high-speed rotation of the chain 21.

The chain support frame 22 is fixed on the outer ring of the bearing seat 19 through bolts; during the rotation of the chain 21 and the sprocket 20, the chain support frame 22 supports the chain 21 to assist the rotation thereof.

One end of the guide rod 5 is arranged on the pressing device 6, and the other end is in sliding fit with the frame 9. The guide rod 5 guides the up-and-down movement of the pressing device 6.

The chain cover 14 is arranged at the top of the outer ring of the bearing seat 19, when the combined chain saw 7 is used for cutting, a large amount of straw board sawdust flies out, and the chain cover 14 can effectively prevent sawdust from splashing everywhere.
