Corn harvester and corn straw guide and support device thereof

Abstract

The invention discloses a corn harvester and a corn straw guide and support device thereof. The guide and support device comprises a support plate which is provided with a front end protrusion, a rear end protrusion, a left protrusion and a right protrusion. Guide structures externally expanding from front to back are arranged between the front end protrusion and the left protrusion as well as between the front end protrusion and the right protrusion respectively; a pushing structure shrinking internally from front to back is arranged between the rear end of each guide structure and each of the left protrusion and the right protrusion; two straw picking mechanisms are respectively arranged on the rear sides of the two pushing structures, are in right-and-left alternative arrangement, and match with respective corresponding pushing structures to form turning passages which are connected with a corn picker in a clearance manner; and a pusher dog is arranged on each straw picking mechanism, is used for pushing corn straws to move along the turning passages and enabling the corn straws to be attached to the pushing and support structures to move. In the process of pushing the corn straws by the corresponding pusher dogs, the corn straws are constantly attached to the corresponding pushing structure to move, so that the corn straws are prevented from toppling, and conveying in standing positions of the corn straws is kept constantly.

Description

technical field [0001] The invention relates to a corn harvester and a corn stalk guiding and supporting device thereof. Background technique [0002] Corn is one of the important food crops. It is widely used as food, feed and industrial raw materials. As a corn harvester for harvesting corn, its functions mainly include ear picking, ear collection and straw processing. According to different straw processing methods, the existing The corn harvester is roughly divided into two types, one is the straw crushing and returning type, and the other is the straw shredding and recycling type. Since corn stalks can be used as silage, industrial raw materials, cultivated edible fungi, etc., it is obvious that the model of straw shredding and recycling is suitable for the comprehensive utilization of corn stalks. The root is cut off, and then the eared corn stalks cut from the root are transported to the ear picking device in a standing position for ear picking; since the planting of...

AI Technical Summary

Problems solved by technology

In this guiding and supporting device, the helical blades on the guide rollers can ensure that the corn stalks are transported to the ear-picking gaps in a standing position when they are cut off, but there are still the following disadvantages: 1. This device is suitable for large and medium-sized corn harvesters, mainly Since the corn stalks are guided and conveyed by guide rollers, the power consumption is large, which cannot meet the needs of the straw chopping and recycling of the small corn harvester; When the corn stalks are guided by the guide rollers to the rear end of the guide rollers, the device is directly pushed into the ear-picking gap by the reel, and the corn stalks are easily dumped during the process of moving the corn stalks by the reel, which affects the chopping operation
