Description

Technical Field

[0001] The utility model relates to the technical field of components for harvesters, in particular to a claw-shaped spring tooth of a reel of a harvester. Background Art

[0002] The spring teeth of the reel of a harvester contact with crops and push the crops under the rotation of the reel to ensure that the crops enter the threshing device. A good spring tooth design can not only reduce the loss of crops during harvesting and the damage to the harvested products, but also has a good effect of righting the lodged crops to ensure the harvesting of the lodged crops.

[0003] Most of the current spring teeth of the reel are metal spring teeth, and there are also some nylon spring teeth. The metal spring teeth are easy to rust, and the metal edges are relatively sharp, which will cause damage and loss to the harvested products, and easily entangle the crops on the spring teeth and are not easy to fall off, causing inconvenience and affecting the efficiency of the cutter bar. Although the nylon spring teeth can make up for some shortcomings of the metal spring teeth, both the metal spring teeth and the nylon spring teeth work with a single claw, which has limitations in righting the lodged crops. During operation, there will be a phenomenon of missed grasping, which affects the adaptability of the harvester to complex working conditions in complex farmland and the reeling quality and efficiency of the harvester. Summary of the Utility Model

[0004] The utility model aims to solve the technical problems existing in the prior art. For this reason, an object of the utility model is to provide a claw-shaped spring tooth of a reel of a harvester, which improves the adaptability of the harvester and the reeling quality and efficiency of the harvester by changing the single claw into a three-claw nylon spring tooth and optimizing the design of the edges.

[0005] To solve the above technical problems, the technical solution of the utility model is: a claw-shaped spring tooth of a reel of a harvester, comprising a tooth base and tooth claws, wherein the tooth base is connected to the reeling tube of the reel of the harvester, and the tooth claws are in direct contact with the crops.

[0006] Optionally, the tooth base includes a locking block and a tooth ring. The locking block is provided with a locking hole and is locked by a screw. The locking block is located on one side of the tooth ring, and there is an opening in the middle of the locking block. The opening is the installation inlet of the reeling tube of the reel of the harvester.

[0007] In order to fix the spring tooth to the reel, the tooth ring is provided with a connection hole and is fixedly connected to the reeling tube of the reel of the harvester by a screw, and the reeling tube of the reel of the harvester is installed at the tooth ring.

[0008] In order to reduce the loss and damage of the crops by the spring tooth and the entanglement of the crops on the spring tooth, the tooth claws include a middle tooth claw and side tooth claws. The tooth heads of the middle tooth claw and the side tooth claws are rounded corners, and the transition at the gap between the middle tooth claw and the side tooth claws is a rounded corner.

[0009] Optionally, both the tooth base and the tooth claw are made of nylon material.

[0010] After adopting the above structure, the utility model has the following advantages:

[0011] By changing the number of claws of the spring teeth, changing the traditional single claw to a triple claw, the spring teeth can grasp crops more easily. For lodging crops, the righting effect is better, improving the reaping efficiency and quality of the harvester; optimizing the tooth head of the spring teeth to be rounded, and the transition between the tooth claws to be rounded, and selecting nylon material. During operation, it can reduce the impact of the spring teeth on the crops, reduce damage and loss to the crops, and prevent the inconvenience caused by the crops being wound around the spring teeth; through the two screws at the locking hole and the connecting hole for fastening, it ensures that the spring teeth are firmly fixed on the reaping tube of the harvester's reel, and the installation and disassembly are convenient.

[0012] The above summary is only for the purpose of the specification and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments and features described above, further aspects, embodiments and features of the utility model will be readily apparent by reference to the drawings and the following detailed description.

The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present application and should not be construed as a limitation of the present application.

[0017] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "install", "connect", and "couple" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two elements or the interaction relationship between two elements. 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.

[0018] Combined with the attached Figure 1 and Figure 2 , a claw-shaped elastic tooth of a harvester reel, comprising a tooth base 1 and a tooth claw 2. The tooth base 1 is connected to the reel tube of the harvester reel. The tooth claw 2 is in direct contact with the crop. The tooth base 1 includes a locking block 101 and a tooth ring 102. The locking block 101 is provided with a locking hole 3 and is locked by a screw. The locking block 101 is located on one side of the tooth ring 102. There is an opening 4 in the middle of the locking block 101. The opening 4 is the installation inlet of the reel tube of the harvester reel. The tooth ring 102 is provided with a connection hole 5 and is fixedly connected to the reel tube of the harvester reel by a screw. The reel tube of the harvester reel is installed at the tooth ring 102.

[0019] The tooth claw 2 includes a middle tooth claw 201 and a side tooth claw 202. The tooth heads of the middle tooth claw 201 and the side tooth claw 202 are rounded. The transition at the gap between the middle tooth claw 201 and the side tooth claw 202 is rounded, ensuring reduced damage and loss to the crop and reducing the entanglement of the crop around the elastic tooth.

[0020] Both the tooth base 1 and the tooth claw 2 are made of nylon material, or other materials with good elasticity and toughness.

[0021] The claw design can better fork up the crop and better right the lodged crop. The tooth heads of the elastic teeth are rounded instead of having some sharp edges. Using nylon material can reduce the impact on the crop, reduce damage and loss to the crop. The transition at the gap between the middle tooth claw 201 and the side tooth claw 202 is rounded instead of being acute, which can prevent the crop from entangling around the elastic tooth. The two screws at the locking hole 3 and the connection hole 5 are tightly fastened, with firm fastening and convenient installation and disassembly.
