Fig. 1 is a plan view of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments, which are illustrative, not restrictive, and the scope of the invention should not be limited thereto.
A corn stalk reeling and feeding device, please refer to fig. 1, the invention point is:
a group of feeding devices are respectively arranged at the front end of each group of stalk-pulling rollers of the header, and each group of feeding devices comprises two guide plates 2 which are symmetrically arranged and a left reel wheel 3 and a right reel wheel 3 which are symmetrically arranged.
The both sides deflector sets up in the place ahead that corresponds group's stem drawing roller, the both sides deflector is relative inboard personally submits curved bent plate, constitute the feeding entry end between the front end apical part position of both sides deflector, constitute the feeding exit end before the rear end of both sides deflector, the feeding exit end links up with the leading-in awl front end that corresponds group's stem drawing roller, it is specific, the rear end of left side deflector extends backward to the front end of dextrorotation stem drawing roller 5, and the rear end of right side direction extends backward to the front end of levogyration stem drawing roller 4, by feeding entry end to feeding exit end direction between the deflector of both sides, the feeding bore reduces gradually.
The two reel wheels are tooth-shaped wheels with tooth shapes uniformly distributed on the surfaces, and the tooth shapes adopt involute tooth shapes. The two reel wheels are respectively arranged above the two guide plates. The front section of the circumference where the tooth ends of the two reel wheels are located is positioned behind the tip of the front end of the corresponding guide plate, and the rear section of the circumference where the tooth ends of the two reel wheels are located is positioned behind the front end of the corresponding stem-pulling roller guide cone. The two reel wheels are respectively connected with two reel transmission boxes arranged on the ear picking frame of the header through respective wheel shafts 1, the reel transmission boxes are connected with the ear picking box 7 through transmission shafts 6, wherein the reel transmission boxes are arranged below the corresponding reel wheels and are covered in the drawing, which is not shown. The reel transmission case is a transmission mechanism which is arranged in the case body and is engaged with a gear, and the reel transmission case has the following functions: the power is input through the transmission shaft, and the power in the horizontal direction is converted into the power in the vertical direction through gear engagement so as to drive the corresponding reel to rotate. The two reel wheels of each group of feeding devices move oppositely and relatively.
In the above structure, further: two guide plates of two adjacent groups of feeding devices close to one side are integrally connected at the top part of the front end through an arc transition surface, so that the problem of stalk leakage between the feeding inlet ends of the two adjacent groups of feeding devices is avoided, the effective operation range is wider, the feeding effect is better, and especially the operation condition of non-aligned harvesting is realized.
In the above structure, further: the reel wheels of two adjacent groups of feeding devices are arranged in a staggered manner. Specifically, when the two reel wheels of the feeding device are located at a low position, the two reel wheels of the two feeding devices adjacent to each other on the left and right sides are both located at a high position, and when the two reel wheels of the feeding device are located at a high position, the two reel wheels of the two feeding devices adjacent to each other on the left and right sides are both located at a low position. By adopting the arrangement mode of the reel, the reel teeth can be lengthened as much as possible under the condition that the structure of the integral cutting table is compact as much as possible, the reel action surface is enlarged, and a better feeding effect is achieved.
Although the embodiments of the present invention and the accompanying drawings are disclosed for illustrative purposes, those skilled in the art will appreciate that: various substitutions, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims, and therefore, the scope of the present invention is not limited to the disclosure of the embodiments and the accompanying drawings.
