Abstract

The invention discloses an agricultural machine for transporting and broadcasting operation of organic fertilizer such as animal manure and compost, and particularly relates to a crushing and throwing blade of an animal manure broadcast sower. The crushing and throwing blade of the animal manure broadcast sower comprises a rotating roll shaft and a main blade body welded, connected and fixed to the rotating roll shaft. The end of the main blade body is connected with an auxiliary blade body. The main blade body and the auxiliary blade body are connected through a bolt assembly. The bolt assembly comprises a bolt and a nut. The bolt comprises a bolt head and a threaded rod. The nut is in threaded connection to the threaded rod. A spiral steel wire is arranged in the nut. An annular groove where the spiral steel wire is installed is formed in the inner wall of the nut. The diameter of the spiral steel wire is equal to the thread pitch of a thread on the threaded rod, and the spiral steel wire is connected to the threaded rod in a sleeving manner. The crushing and throwing blade overcomes the technical defect that an auxiliary blade body is prone to disengaging from a main blade body in the prior art, and by means of the crushing and throwing blade of the animal manure broadcast sower, the auxiliary blade body can be prevented from disengaging from the main blade body.

Description

technical field [0001] The invention relates to an agricultural machine for transporting and spreading organic fertilizers such as manure and compost, in particular to a manure spreader for crushing and spreading blades. Background technique [0002] During mechanical spreading, the manure or compost is usually loaded in the box of the manure spreader, and the manure or compost is sent to the fertilizer crushing and spreading mechanism at the end of the box by the fertilizer conveying system. The fertilizer crushing and spreading mechanism is equipped with a roller shaft with blades, and the rotating roller shaft crushes and spreads the fertilizer sent by the fertilizer conveying system through the blades welded to it. Because manure and compost often contain stones and various hard debris, the wear and damage of the blades is inevitable, especially the upper end of the blades is more severely worn. Because the blade and the roller shaft are welded together, it is very diff...
