Description

Technical Field

[0001] This utility model relates to the technical field of harvester parts, specifically to a snapping finger that prevents the rice from getting caught on branches. Background Technology

[0002] Currently, the reel spring mechanism used on combine harvester headers is poorly designed, mostly made of spring steel wire. This leads to problems such as ear breakage, pod rupture, snagging on branches, and high grain loss during harvesting. Furthermore, the springs are all straight rods with a small contact area with the crop, making them susceptible to various losses, resulting in a high failure rate, high maintenance costs, and impacting the combine harvester's operational efficiency. Therefore, a new reel spring mechanism is needed to address these issues. Utility Model Content

[0003] This invention proposes a reeling finger that avoids snagging on branches, solving the problem in the prior art where the reeling finger on the harvester easily snags the ears of grain onto branches, leading to harvesting losses.

[0004] The technical solution of this utility model is as follows:

[0005] A reeling finger to prevent snagging on branches, the reeling finger includes a mounting base and a finger body. The finger body is disposed on the mounting base and includes a deformable finger, a baffle, and an elastic plate. The deformable finger is disposed on the mounting base, the baffle is disposed on the mounting base and located on the side of the deformable finger that reels the branches, and the elastic plate is disposed on the mounting base and located on the side of the deformable finger that is away from the branches. The elastic plate is used to abut against the deformable finger to apply elastic force.

[0006] The deformation spring gradually decreases in width from one end near the mounting base to the other end, and the reeling side of the deformation spring is provided with multiple reeling notches.

[0007] The baffle has a tendency to press against the deformed spring-loaded reed side.

[0008] The baffle is inclined and the baffle and the shovel side of the deformation spring are inclined to the same side.

[0009] The elastic plate has a tendency to press against the deformation spring finger, and the elastic plate is an arc-shaped plate.

[0010] The mounting base is provided with a mounting opening, the mounting opening has two locking lugs, and the mounting base is also provided with a fastener, the fastener passing through the locking lugs to lock the mounting opening.

[0011] The working principle and beneficial effects of this utility model are as follows:

[0012] This utility model discloses a reeling spring that prevents snagging on branches. A spring body is connected to a mounting base. The spring body is optimized and divided into three parts. A deformable spring is connected to the mounting base, which is used to mount the spring onto a rotating base. Multiple reeling springs can be circumferentially mounted on the rotating base. One side of the deformable spring is used to reel the crop into the harvester for harvesting. A baffle is provided on the reeling side of the deformable spring, abutting against one side of the deformable spring and blocking the connection between the deformable spring and the mounting base. In some cases, this design avoids the crop from getting caught in the branches or ears of grain. However, spring steel wire reeling fingers are prone to piercing into the crop stems and can also cause crops to get stuck in the spring section of the wire. On the opposite side of the reeling side of the deformable reeling finger, an elastic plate is installed on the mounting base. The elastic plate abuts against the deformable reeling finger. When reeling, the deformable reeling finger deforms and compresses the elastic plate, causing it to deform. The elastic force generated by the deformed plate acts on the deformable reeling finger. The deformable reeling finger provides a certain degree of cushioning during reeling, avoiding damage to the crop and reducing harvest losses. Attached Figure Description

[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0018] like Figures 1-2As shown in the figure, this embodiment proposes a reeling finger to avoid snagging on branches. The reeling finger includes a mounting base 1 and a finger body. The finger body is disposed on the mounting base 1. The finger body includes a deformable finger 2, a baffle 3 and an elastic plate 4. The deformable finger 2 is disposed on the mounting base 1. The baffle 3 is disposed on the mounting base 1 and is located on the side of the deformable finger 2 that reels the branches. The elastic plate 4 is disposed on the mounting base 1 and is located on the side of the deformable finger 2 that is away from the branches. The elastic plate 4 is used to abut against the deformable finger 2 to apply elastic force.

[0019] In this embodiment, a crop-reeling spring that avoids snagging on branches is disclosed. A spring body is connected to a mounting base 1. The spring body is optimized and divided into three parts. A deformable spring 2 is connected to the mounting base 1, which is used to mount the crop onto a rotating base. Multiple crop-reeling springs can be circumferentially mounted on the rotating base. One side of the deformable spring 2 is used for crop reeling, guiding the crop into the harvester for harvesting. A baffle 3 is provided on the crop-reeling side of the deformable spring 2, abutting against one side of the deformable spring 2. The baffle 3 covers the connection between the deformation spring 2 and the mounting base 1 to prevent the branches from getting caught and the ears from being pulled. At the same time, on the opposite side of the deformation spring 2 on the pulling side, the mounting base 1 is provided with an elastic plate 4. The elastic plate 4 abuts against the deformation spring 2. When pulling the rice, the deformation spring 2 deforms and squeezes the elastic plate 4 to deform it. The elastic force generated after the elastic plate 4 deforms acts on the deformation spring 2. The deformation spring 2 has a certain buffer when pulling the rice to avoid damage to the crop and reduce harvesting losses.

[0020] The width of the deformation spring 2 gradually decreases from one end near the mounting base 1 to the other end, and the deformation spring 2 has multiple plucking notches 5 on the plucking side.

[0021] Based on the above embodiments, the deformation spring 2 has a gradually narrowing structure, with the width gradually decreasing from one end near the mounting base 1 to the other end. The crop-pulling side of the deformation spring 2 has an inclined side shape, which reduces the processing material of the deformation spring 2 and makes the deformation spring 2 lighter. Multiple crop-pulling notches 5 are set on the edge of the crop-pulling side, which helps to pull the crop into the harvester and prevents the crop from slipping off the crop-pulling side during the pulling process.

[0022] The baffle 3 has a tendency to press against the reeling side of the deformable spring finger 2.

[0023] Based on the above embodiment, the baffle 3 is set on the mounting base 1. The baffle 3 is set to be elastic, so that the baffle 3 always has the tendency to press against the deformation spring 2. When the deformation spring 2 deforms when it picks the rice, the baffle 3 can still stay against the edge of the deformation spring 2 on one side, so as to avoid the crop getting stuck in the deformation spring 2 and causing loss.

[0024] The baffle 3 is inclined and the baffle 3 and the deformation spring 2 have the same tilting trend on the reeling side.

[0025] Based on the above embodiments, the baffle 3 can be configured as an inclined structure. The angle of inclination of the baffle 3 is consistent with the edge inclination trend of the deformation spring 2 on the reeling side. Then, on the reeling side, the baffle 3 and the edge of the deformation spring 2 form a continuous inclined edge curve.

[0026] The elastic plate 4 has a tendency to press against the deformation spring finger 2, and the elastic plate 4 is an arc-shaped plate.

[0027] Based on the above embodiment, the elastic plate 4 is set on the mounting base 1 and is set as an arc plate. The elastic plate 4 also has the tendency to press against the deformation spring finger 2. When the deformation spring finger 2 deforms during the picking of grain, the deformation spring finger 2 squeezes the elastic plate 4, the elastic plate 4 deforms and applies elastic force to the deformation spring finger 2. After the picking of grain is completed, the elastic force of the elastic plate 4, combined with the deformation recovery ability of the deformation spring finger 2 itself, causes the deformation spring finger 2 to return to its original position.

[0028] The mounting base 1 is provided with a mounting opening 6, the mounting opening 6 has two locking lugs 7, and the mounting base 1 is also provided with a fastener 8, which passes through the locking lugs 7 to lock the mounting opening 6.

[0029] Based on the above embodiments, the mounting base 1 is provided with a mounting opening 6, which is a mounting hole structure with an openable break. There are two locking lugs 7 on both sides of the break. The two locking lugs 7 are locked by fasteners 8. The fasteners 8 can be bolts and nuts, but are not the only ones. This allows the mounting opening 6 to hold the rod or shaft and other mounting parts, thus playing a role in installation and fastening.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
