Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. In the description of the present application, it is to be understood that the terms "left side", "right side", "upper part", "lower part", etc., indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and that "first", "second", etc., do not represent an important degree of the component parts, and thus are not to be construed as limiting the present invention. The specific dimensions used in the present example are only for illustrating the technical solution and do not limit the scope of protection of the present invention.

A picking mechanism for picking up straw off a field is generally shown in figure 1, when the picking mechanism works for a long time, a grass chain is formed between a blade of an auger and a tooth blocking piece, so that the auger is blocked; simultaneously, when the tooth is hugged the grass, because it is gapped between tooth and the outside guard shield to hug, and the clearance is great, so in long grass gets into the clearance, lead to the B district bearing that figure 5 shows to be twined by long grass stifled, long grass also can get into the regional formation of picking up dead angle in the A district that figure 6 shows and pile up, cause the trouble, the final result that obtains is the life who influences whole structure, has reduced work efficiency.

Based on the reasons, the invention provides a structure as shown in fig. 2, which is an improvement of a picking structure body in the prior art, the picking structure body can meet the requirement of a large range at the lowest cost, in the drawing, an auger 7 and a raking tooth are installed on the picking structure body, the raking tooth sends long raked grass into the auger for picking, a baffle shield 3 and a right baffle shield 1 are respectively installed at two ends of the raking tooth, a baffle reinforcing plate 9 shown in fig. 9 is fixedly arranged in the baffle shield, a right baffle reinforcing plate 8 shown in fig. 8 is fixedly arranged in the right baffle shield, the shape of the baffle reinforcing plate matches the radian of the inner side wall of the baffle shield, and the shape of the right baffle reinforcing plate matches the radian of the inner side wall of the right baffle shield; as can be seen clearly from the figure, the width of the baffle reinforcing plate is greater than that of the right baffle reinforcing plate, which depends on the maximum diameter of the tooth-raking track or the movable outer edge of the fixing seat of the structure, and the gap of the width (depth) is less than 3mm after the reinforcing plate is arranged; after separation blade reinforcing plate and right separation blade reinforcing plate set up, the machine is picking up the in-process, and long grass does not get into the regional space of B district bearing, can avoid the bearing because twine the damage that the grass leads to.

Fig. 8 and 9 also show that the grass guide plate 10 is fixedly arranged on the outer side wall of the baffle shield, the grass guide plate is also fixedly arranged on the outer side wall of the right baffle shield, the grass guide plates are fixed in a welding mode, fig. 5 is a schematic diagram of the mechanism operation, and it can be seen that long grass is directly guided by grass to directly enter a working area of the auger blade, so that the grass chain phenomenon caused by accumulation of the grass entering dead angle areas at two sides of the area a for picking up is effectively reduced;

7 a-7 b show, install on the tooth of hugging and hug tooth separation blade 2, a plurality of tooth separation blades of hugging weld together, weld flitch 11 on the relative screw feeder's of tooth separation blade lateral wall, the clearance between welding flitch back and the screw feeder blade satisfies 40mm-60mm, right fender guard shield and separation blade guard shield can be assisted in the setting of flitch this moment, further play the effect of long grass guide, will long grass directly get into screw feeder department.

In a preferred embodiment, the grass guiding plate on the right flap shield, the grass guiding plate on the flap shield and the patch are in the same curvature, and when the three are installed, the three can form a whole when viewed from the side.

In order to better realize the fixation of each part, as shown in fig. 3, the right baffle shield and the grass guiding plate are fixed by round-head square-neck bolts 4, and nuts 5 (the model is M8) are sleeved on the round-head square-neck bolts (the model is M8 multiplied by 20) for fastening; as shown in fig. 4, the guard shield and the grass guiding plate are fixed by bolts 6 (model is M8 × 20).

Through the explanation to the embodiment, the service life of the tooth raking bearing can be effectively prolonged, the formation of a grass chain is reduced, the occurrence of faults is reduced, and therefore the working efficiency of the whole structure is improved.
