Description

Technical Field

[0001] This application relates to the technical field of agricultural machinery equipment, and particularly relates to a reel chain of a corn harvester. Background Art

[0002] During the operation, the reel chain on the corn harvester pulls the straw and ears backward and conveys them to the next process. Therefore, the cutter bar has a key impact on the harvesting performance of the corn harvester. As a key component on the cutter bar responsible for the feeding function, the working condition of the reel chain will directly affect the feeding efficiency of the cutter bar, thereby affecting the harvesting efficiency of the harvester. The reel chain includes a chain body and a plurality of spaced-apart attachment plates, and the attachment plates are installed and fixed on the chain body.

[0003] The attachment plates on two adjacent reel chains are installed on the same horizontal plane, and the positions of the attachment plates on the reel chain are staggered with each other. When one of the reel chains gets stuck due to material debris, weeds, etc., the attachment plate on this chain will collide with the attachment plate on the other adjacent chain, causing damage to the chain and reducing the service life of the chain.

[0004] The information disclosed in this background art section is only intended to enhance the overall understanding of this application and should not be regarded as an admission or any form of implication that this information constitutes prior art already known to those of ordinary skill in the art. Summary of the Invention

[0005] The purpose of the present invention is to provide a reel chain of a corn harvester, which avoids the defect that when one of the chains gets stuck during operation, it will collide with the attachment plate on the other adjacent chain and damage the chain.

[0006] To achieve the above purpose, the present application is implemented by the following technical solutions:

[0007] A reel chain of a corn harvester includes two oppositely arranged reel chain bodies. Left attachment plate assemblies and right attachment plate assemblies are respectively arranged on the two reel chain bodies. The reel chain bodies are inclined and the upper sides are far away from each other;

[0008] On the side where the two reel chain bodies are close to each other, there is a gap between the horizontal projections of the left attachment plate assembly and the right attachment plate assembly

[0009] Optionally, the inclination angle α of the reel chain body ranges from 35° to 55°.

[0010] Optionally, the attachment plate assembly includes an integrally formed mounting surface 、 a main body plane and a reel plane. The side of the mounting surface is provided with the main body plane and the reel plane. The reel plane is connected to the main body plane. The main body plane is horizontally installed, and the mounting surface is fixedly connected to the reel chain body.

[0011] Optionally, the included angle between the main body plane and the mounting surface is complementary to the inclination angle α of the main body of the reel chain.

[0012] Optionally, the reel surface is an inclined surface structure, and the included angle with the longitudinal plane is 12° to 18°.

[0013] Optionally, the gap between the left attachment plate assembly and the right attachment plate assembly is between 3 mm and 6 mm.

[0014] Optionally, the attachment plate assemblies are evenly spaced on the main body of the reel chain.

[0015] Optionally, there are two mounting surfaces of the attachment plate assembly. The two mounting surfaces are arranged in parallel to clamp the edge of the main body of the reel chain, and the two mounting surfaces are fixed to the edge of the main body of the reel chain through fasteners.

[0016] Compared with the prior art, the beneficial effects achieved by the present application are as follows:

[0017] By setting the angle of the main body of the reel chain to adjust the angle of the attachment plate assembly, the force on the material is made uniform. There is a gap between the two attachment plate assemblies, which solves the problem that the attachment plates on the traditional reel chain must be alternately misaligned with the attachment plates on the adjacent chain during installation. Thus, the defects caused by the alternate misalignment of the attachment plates during the installation of the reel chain are also avoided, that is, when one of the chains is stuck due to material debris or other reasons, the attachment plate on this chain will collide with the attachment plate on the adjacent chain, damaging the chain. The attachment plates of the two adjacent chains of the present invention do not interfere with each other. Therefore, the attachment plates on the reel chain do not need to be alternately misaligned with the attachment plates on the adjacent chain during installation. Description of the Drawings

[0025] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The description of at least one exemplary embodiment below is actually only illustrative and in no way limits the present application and its application or use.

[0026] Embodiment 1:

[0027] A corn harvester reel chain, as Figure 1 and Figure 2 shown, includes a reel chain main body 1. There are two oppositely arranged reel chain main bodies 1. A left attachment plate assembly 2 and a right attachment plate assembly 3 are respectively arranged on the two reel chain main bodies 1. The reel chain main bodies 1 are inclined and the upper sides are far away from each other;

[0028] On the side where the two reel chain main bodies 1 are close to each other, there is a gap between the horizontal projections of the left attachment plate assembly 2 and the right attachment plate assembly 3.

[0029] By setting the angles of the attachment plate assemblies of the reel chain main body 1, the force on the material is made uniform. A gap is provided between the left attachment plate assembly 2 and the right attachment plate assembly 3, solving the problem that the attachment plate assemblies on the traditional reel chain must be alternately misaligned with the left attachment plate assembly 2 and the right attachment plate assembly 3 on the adjacent chain during installation. Thus, the defect caused by the alternate misalignment of the attachment plates during the installation of the reel chain is also avoided, that is, when one of the chains is stuck due to material debris or other reasons, the left attachment plate assembly 2 on this chain will collide with the right attachment plate assembly 3 on the adjacent chain, damaging the chain. The left attachment plate assembly 2 and the right attachment plate assembly 3 of the present utility model do not interfere with each other. Therefore, the left attachment plate assembly 2 on the reel chain main body 1 does not need to be alternately misaligned with the right attachment plate assembly 3 on the adjacent reel chain main body 1 during installation.

[0030] As Figure 1 and Figure 3As shown, the angle α ranges from 35° to 55°, and 45° is taken in this embodiment. The attached plate assembly includes a mounting surface 3-1, and a main plane 3-2 and a reeling surface 3-3 are arranged on the side of the mounting surface 3-1. The main plane 3-2 is horizontally installed, and the angle between the main plane 3-2 and the mounting surface 3-1 is complementary to the mounting angle α between the reeling chain body 1 and the horizontal plane, so that when the reeling chain is in the working position, the main plane 3-2 is horizontal, which reduces the possibility of staggered collision between the left attached plate assembly 2 and the right attached plate assembly 3, and makes the force on the material more uniform, thereby improving the working efficiency.

[0031] The mounting surface 3 - 1 is flush with the main body of the reed chain, thus avoiding the possibility of a collision between the left attachment plate assembly 2 and the right attachment plate assembly 3 due to one side getting stuck in the traditional staggered arrangement, causing greater losses.

[0032] The attachment plate assembly has two mounting surfaces 3-1, which are arranged in parallel and used to clamp the edge of the reed chain body 1. The two mounting surfaces 3-1 are fixed to the edge of the reed chain body 1 by fasteners, so that the left attachment plate assembly 2 and the right attachment plate assembly 3 are stably connected to the reed chain body 1.

[0033] The gap between the left attached plate assembly 2 and the right attached plate assembly 3 is between 3 mm and 6 mm, and the plowing effect is better.

[0034] Embodiment 2

[0035] Based on the first embodiment, an implementation method of an attachment plate assembly is provided.

[0036] Different from the first embodiment, Figure 4 As shown, the plowing surface 3 - 3 is an inclined slope structure, and the angle between it and the longitudinal plane is 12° to 18°. The left attached plate assembly 2 and the right attached plate assembly 3 are evenly spaced and arranged on the plowing chain body 1 .

[0037] The inclined surface structure increases the contact area between the reed-pulling surface 3-3 and the material, so that the material is evenly stressed and the conveying efficiency is improved. The reed-pulling effect is better when the angle is 12° to 18°.

[0038] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only used to explain the relative position relationship, movement, etc. between the components in a certain posture. If the specific posture changes, the directional indication will also change accordingly. It is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application.

[0039] In the description of the present application, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0040] The above are only the preferred embodiments of the present application. It should be pointed out that for those of ordinary skill in the technical field of the present application, without departing from the technical principle of the present application, several improvements and modifications can also be made, and these improvements and modifications should also be regarded as the protection scope of the present application.
