Bundling machine large needle and preparation method thereof

Abstract

The invention discloses a bundling machine large needle and a preparation method thereof, and relates to the technical field of agricultural mechanical equipment. The bundling machine large needle comprises a large needle, a cover plate, a connecting rod and a protection box, wherein the large needle and the connecting rod are fixedly connected together through a fixing shaft, meanwhile, the cover plate is buckled outside the fixing shaft and fixedly installed on the bottom wall of the large needle through a connecting bolt, the large needle is protected and is prevented from falling off from the end of the connecting rod in the working process, the large needle works more safely and reliably, in addition, the end, away from the fixing shaft, of the connecting rod is fixedly installed at the output end of a driving mechanism, the driving mechanism drives the connecting rod to rotate, and therefore, the connecting rod drives the large needle to rotate; and meanwhile, the protection box is arranged outside the connecting rod, a reinforcing block is arranged in the connecting rod, a sliding mechanism is installed in the reinforcing block, the connecting rod is installed in a fan-shaped cavity of the protection box in a sliding mode through the sliding mechanism, the connecting rod is limited through the fan-shaped cavity, horizontal movement of the connecting rod is avoided, and shaking of the large needle is prevented.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery and equipment, in particular to a large needle for a baler and a preparation method thereof. Background technique [0002] my country is a large agricultural country with abundant biomass resources. It is estimated that the annual output of crop straw in my country is more than 700 million tons. However, due to the difficulty in picking up, loose materials, and high transportation costs, in order to solve the difficulty in picking up straw and the high cost of transportation, straw straw is now widely used. Straw baler, straw baler, in the existing small square baler, the needle frame drives the rope-tying needle to move during the knotting process, and moves the large needle from the lower end of the bale to the upper end of the bale for tying. Knot, during the movement of the large needle, due to the vibration generated by the machine itself or the action of external force, the larg...

[0002]China is a large agricultural country with abundant biomass resources. It is estimated that the annual output of crop straws in China is more than 700 million tons, but due to the difficulty in picking up, loose materials and high transportation costs , in order to solve the difficulty of picking up straw and transporting Chen Bengao, straw balers are widely used now, straw balers, in the existing small square baler balers, the needle frame drives the rope-tying needle to move during the knotting process, and the large The needle moves from the lower end of the bale to the upper end of the bale to tie a knot. During the movement of the large needle, due to the vibration of the cow when the machine is running or the action of external force, the large needle often shakes, which will make the knotting The position of the rope needle is shifted, which leads to the failure of knotting. The operator needs to manually reset the large needle. The normal work of the baler
