Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a corn machine chain structure of a special-shaped tooth. BACKGROUND
[0002] The corn harvester is composed of a cutting platform, an elevator, a peeling machine, a fruit ear box and several major mechanisms.
[0003] One installation mode is that two same groups of chain are assembled on the same plane, the distance L between the same group of chain transmission tension pulleys is generally between (165-190) mm, the two chain teeth are staggered, and the interference during normal work is prevented. INVENTION CONTENTS
[0004] The utility model discloses a corn machine chain structure of a special-shaped tooth.
[0005] The utility model discloses a corn machine chain structure of a special-shaped tooth, which comprises a chain, a plurality of teeth are arranged on the chain, the rear end of the tooth is fixedly connected with the chain, and the front section and the middle section of the tooth are provided with a gap for the adjacent tooth on the chain.
[0006] Further, the tooth is formed by bending a thin plate, and the front section and the middle section of the tooth are recessed towards the upper side and the lower side.
[0007] Further, the rear end of the tooth is of an open structure, and the tooth is clamped on the chain through the open structure.
[0008] Further, the tooth and the chain are fixedly connected through at least two pins, and the pins pass through the tooth and the chain in sequence.
[0009] Further, the two ends of the chain are respectively engaged with a gear, and the gear is installed on a rack.
[0010] Compared with the prior art, the utility model has the following advantages:
[0011] By setting the let gap above or below the front and middle sections of the tines, the collision or interference between the tines on adjacent raking chains during operation can be effectively avoided, thereby improving the raking efficiency and reducing mechanical wear and energy loss.
[0012] The tines are made of thin plates and are recessed towards the upper and lower sides. This design not only reduces the weight of the tines but also increases the contact area between the tines and the corn stalks, improving the raking effect. At the same time, this shape is more easily adapted to corn stalks of different angles and densities, enhancing the adaptability of the machine.
[0013] The rear end of the tine is designed as an open structure and is fixedly connected to the raking chain through a pin. This installation method not only simplifies the assembly process but also facilitates maintenance and replacement in the later stage. The pin connection method also ensures the firmness between the tine and the raking chain, improving the stability of the overall structure.
[0014] The two ends of the raking chain are respectively meshed with a gear, which is installed on the rack. This transmission method makes the operation of the raking chain more stable and reliable, while also ensuring the continuity and uniformity of the tines during raking. In addition, the compact structure design also improves the overall performance and efficiency of the machine. BRIEF DESCRIPTION OF DRAWINGS

[0018] In order to deepen the understanding of the present application, the present application will be further described in conjunction with the embodiments and drawings, which are only used to explain the present application and do not constitute a limitation on the protection scope of the present application.
[0019] As shown in Figs. 1-2 , the raking chain 1, the tine 2, the gear 3, the rack 4, and the let gap 5;
[0020] A corn machine raking chain structure with special-shaped tines includes a raking chain 1, a plurality of tines 2 are provided on the raking chain 1, the rear end of the tine 2 is fixedly connected to the raking chain 1, and let gaps 5 are provided above or below the front and middle sections of the tine 2. The let gap 5 is used to give way to the tine 2 on the adjacent raking chain 1.
[0021] In the present embodiment, the poking tooth 2 is made by bending a thin plate, and the front and middle sections of the poking tooth 2 are recessed towards the upper and lower sides.
[0022] In the present embodiment, the rear end of the poking tooth 2 is of an open structure, and the poking tooth 2 is clamped on the poking chain 1 through the open structure.
[0023] In the present embodiment, the poking tooth 2 and the poking chain 1 are fixedly connected through at least two pins, which are sequentially inserted through the poking tooth 2 and the poking chain 1.
[0024] In the present embodiment, the two ends of the poking chain 1 are respectively engaged with a gear 3, and the gear 3 is installed on a frame 4.
[0025] Working principle: the poking chain 1 with the special-shaped poking tooth 2 solves the problem of interference and collision of the poking tooth 2 in the transmission process due to the jumping of the tooth, greatly reduces the failure of the working components, and improves the working efficiency of the whole machine; also solves the complex transmission structure of the upper and lower layers of the machine body designed to solve the collision of the poking tooth 2, greatly reduces the production and design cost.
