Description
Technical Field
[0001] The utility model relates to the technical field of harvester components, in particular to a novel corn harvester stem pulling bar. Background Art
[0002] The corn harvester's stalk puller is a critical component in the corn harvesting process, responsible for pulling the corn stalks away from the crop stems. The design and functionality of the stalk puller offer significant advantages in improving harvesting efficiency, reducing machine failures, and saving costs. The stalk puller ribs are a key component of the stalk puller. Their specific design and arrangement allow the gaps between the ribs to gradually decrease as the stalks move deeper into the stalk puller, allowing for rapid pulling of the stalks.
[0003] The design of the stalk pullers needs to consider preventing blockages and omissions. Through appropriate spacing and arrangement, the stalk pullers ensure that the stalks are completely pulled away during the harvesting process, avoiding blockages and omissions, thereby greatly improving harvesting efficiency. The working surfaces of the stalk pullers currently available on the market include curved, blade-shaped, and serrated surfaces. In frosty and humid weather, the surface of the corn stalks contains moisture. In lower temperatures, the air moisture adhering to the corn stalks freezes, forming a layer of ice with a high hardness. In these weather conditions, curved stalk pullers lack grip on the corn stalks and are prone to slipping, affecting the pulling effect and causing stalk accumulation or blockage inside the harvester. This not only affects the normal operation of the harvester but can also cause mechanical failure or damage. While blade-shaped and serrated stalk pullers have a strong grip, their sharp working surfaces can cause the corn stalks to break and break off, generating a large amount of impurities, increasing the load on the elevator, increasing fuel consumption, and causing malfunctions. Utility Model Content
[0004] In order to overcome the above technical problems, the utility model provides a new type of corn harvester stem pulling rib with reasonable structural design, sufficient biting force on corn stalks, good stem pulling effect, and not easy to cause corn stalk breakage and tip breakage.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A new type of corn harvester stem pulling ribs, multiple stem pulling ribs are arranged on the outer surface of the stem pulling roller in the circumferential direction, and the characteristics are that the stem pulling ribs are composed of the same number of high stem pulling ribs and low stem pulling ribs alternately, and the interval between each high stem pulling rib and each low stem pulling rib is the same. The high stem pulling ribs include a high stem pulling rib long platform, and the high stem pulling rib long platform is fixedly connected with a boss, and the boss is fixedly connected with a spike. The high stem pulling rib long platform, the boss and the spike are integrated into one, and the boss is evenly distributed on the high stem pulling rib long platform. The low stem pulling ribs include a low stem pulling rib long platform, and the low stem pulling rib long platform is provided with grooves, and the grooves are evenly distributed on the low stem pulling rib long platform.
[0007] Furthermore, the groove is consistent with the overall shape formed by the boss and the spike, and the outline of the groove is slightly larger than the outer outline of the entire structure formed by the boss and the spike.
[0008] Furthermore, the transition angles around the high-tension stem bar strip platform and the low-tension stem bar strip platform are all rounded.
[0009] Furthermore, the high-tension stem bars and the low-tension stem bars are both made of manganese steel.
[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: the new corn harvester stalk pulling ribs have a uniform bite force on the stalks, which prevents the stalks from slipping and does not excessively damage the stalk surface. The utility model is adaptable to various weather conditions, improves the efficiency and effect of stalk pulling, and reduces the impurity rate of the harvest.
[0011] (1) The stem pulling reinforcement is composed of the same number of high stem pulling reinforcements and low stem pulling reinforcements, which can improve the pulling strength of the corn stalks, prevent slipping, and increase the pulling efficiency;
[0012] (2) The high-tension stem reinforcement is provided with bosses and spikes. When working, the spikes penetrate into the corn stalks, which can strengthen the grip of the stem reinforcement on the corn stalks. When the surface of the corn stalks contains moisture, the spikes can still penetrate the surface. When facing frost, the surface of the corn stalks contains ice, and the spikes can pierce the ice layer and then penetrate into the corn stalks. The design of the spikes causes little damage to the surface of the corn stalks and is suitable for various working conditions.
[0013] (3) The high-tension stem ribs are provided with bosses and spikes, and the low-tension stem ribs are provided with grooves. The grooves are consistent with the overall shape formed by the bosses and spikes. The outline of the grooves is slightly larger than the outer outline of the overall shape formed by the bosses and spikes. The design of one concave and one convex, and the concave and convex complement each other, the convex part can penetrate into one side of the corn stalk, and the concave part can accommodate and fix the corn stalk. This complementary relationship makes the grasping more stable. The chimeric nature of the concave and convex design makes the corn stalks less likely to slip during the grasping process. The concave and convex design can disperse the pressure during grasping, reduce the direct pressure on the corn stalks, and thus reduce the risk of damage to the corn stalks.
[0014] (4) The transition angles of the high-tension stem bar strip and the low-tension stem bar strip are all rounded, which can reduce the damage to the corn stalks and prevent the danger to people during the installation and disassembly process;
[0015] (5) Both the high-tension stem bar and the low-tension stem bar are made of manganese steel. Manganese steel has high strength, strong tensile strength and fatigue resistance, as well as good wear resistance. The stem bar can withstand large tension and pressure and is not prone to breakage or deformation, thereby ensuring the stability and durability of the equipment; extending the service life of the stem bar, reducing the replacement frequency, and thus reducing maintenance costs.

[0023] See also Figure 1-Figure 4 A new type of corn harvester stem pulling ribs, a plurality of stem pulling ribs are arranged on the outer surface of the stem pulling roller 1 along the circumferential direction, and the characteristics are that the stem pulling ribs are composed of the same number of high stem pulling ribs 2 and low stem pulling ribs 3 alternately, and the interval between each high stem pulling rib 2 and each low stem pulling rib 3 is the same, the high stem pulling rib 2 includes a high stem pulling rib long platform 201, the high stem pulling rib long platform 201 is fixedly connected with a boss 202, and the boss 202 is fixedly connected with a spike 203, the high stem pulling rib long platform 201, the boss 202 and the spike 203 are integrated, the boss 202 is evenly distributed on the high stem pulling rib long platform 201, the low stem pulling rib 3 includes a low stem pulling rib long platform 301, the low stem pulling rib long platform 301 is provided with a groove 302, and the groove 302 is evenly distributed on the low stem pulling rib long platform 301.
[0024] The groove 302 is consistent with the overall shape formed by the boss 202 and the spike 203 , and the outline of the groove 302 is slightly larger than the overall outer outline of the boss 202 and the spike 203 .
[0025] The transition angles around the high-tension stem bar strip platform 201 and the low-tension stem bar strip platform 301 are all rounded.
[0026] The high-tension stem reinforcement 2 and the low-tension stem reinforcement 3 are both made of manganese steel.
[0027] When the stem pulling roller 1 is working, the corn stalks are grasped by the stem pulling ribs on the stem pulling roller 1, and the spikes 203 on the high stem pulling ribs 2 will penetrate into the surface of the corn stalks, and then cooperate with the low stem pulling ribs 3 to pull the corn stalks downwards. There are grooves 302 on the low stem pulling ribs 3 that match the overall shape formed by the boss 202 and the spikes 203. The design of one concave and one convex, and the concave and convex complementing each other can make the grasping more stable, and it is not easy to slip during the grasping process, and can disperse the surface pressure of the corn stalks during grasping, reduce direct pressure on the corn stalks, and thus reduce the risk of damage to the corn stalks. Compared with the design of the working surface of the high-stem-pulling reinforcement 2 being an arc surface, the design of the high-stem-pulling reinforcement 2 being provided with spikes 203 has good bite force, increases friction, and makes it more reliable to grab the stems, avoids the stems from slipping and the cutting table from being blocked, increases work efficiency, ensures the smooth operation of the harvester, and reduces the failure rate; compared with the design of the working surface of the high-stem-pulling reinforcement 2 being a knife surface and a serrated surface, the design of the high-stem-pulling reinforcement 2 being provided with spikes 203 has better bite force, increases friction, and makes the stems more reliable, avoids the stems from slipping and the cutting table from being blocked, increases work efficiency, ensures the smooth operation of the harvester, and reduces the failure rate; the design of the high-stem-pulling reinforcement 2 being provided with spikes 203 is different from the design of the working surface of the high-stem-pulling reinforcement being a knife surface and a serrated surface. The spikes 203 are evenly distributed on the high-stem-pulling reinforcement strip table 201, and the force applied to the corn stalks is even, causing less damage to the surface of the stalks, with only small thorns, thus avoiding the broken stems and broken tips of the corn stalks during the pulling process, reducing the impurity content, and making the harvesting effect of the whole machine good.
[0028] The design of the present invention has strong adaptability. When facing frosty and humid weather, the surface of the corn stalks contains moisture, and the spikes 203 directly penetrate into the surface of the corn stalks without affecting the grasping of the corn stalks; when facing low temperature weather, the spikes 203 directly pierce the ice layer on the surface of the corn stalks, and then penetrate into the surface of the corn stalks to grasp the corn stalks and pull them down.
[0029] The transition angles around the high-tension stem bar strip platform 201 and the low-tension stem bar strip platform 301 are all rounded. On the one hand, it can reduce the damage to the corn stalks from the side. On the other hand, when people disassemble and install the stem pulling roller 1, the rounded surface is safer than the pointed surface.
[0030] Both the high-tension stem reinforcement 2 and the low-tension stem reinforcement 3 are made of manganese steel. Manganese steel has high strength and toughness. The stem reinforcement made of manganese steel can withstand greater tension and pressure and is not prone to breakage or deformation, thereby ensuring the stability and durability of the equipment. Manganese steel also has good wear resistance. During use, the stem reinforcement needs to withstand constant friction and wear. The wear resistance of manganese steel can extend the service life of the stem reinforcement, reduce the replacement frequency, and thus reduce maintenance costs.
[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
