Problems solved by technology

When the impact stress is greater than the extrusion stress of the grain feeding tooth plate, the grain feeding tooth will be deformed and the riveting hole will become larger
The chain of the grain delivery chain has been working in such a harsh environment for less than a month, and the teeth of the grain delivery chain have loosened, fallen off, and even the chain of the grain delivery chain has broken, which has brought a great impact on the normal harvesting operations.

Embodiment 1

[0018] Embodiment 1, with reference to the accompanying drawings, the grain feeding tooth (1) is an integral type with a closed structure, and its upper and lower parts are directly inserted into the inner chain link, and together with the outer chain plate (2), each adjacent inner chain link is connected to the inner chain The joints are connected into one; the upper and lower parts of the grain feeding tooth (1) are pressed by the outer chain plate (3), and the whole chain is firm and compact after assembly.

[0019] figure 1 Among them, a piece of grain-feeding tooth (1) is riveted every interval of a chain plate, and the density and density of the grain-feeding tooth (1) can also be adjusted appropriately according to actual needs, and evenly distributed on the entire chain.

[0020] figure 2 , the feeding tooth (1) is assembled between the inner chain plate (3) and the outer chain plate (2).

Embodiment 2

[0022] Embodiment 2, assembled according to the form of the above embodiment 1, if the shape of the grain feeding tooth (1) is slightly modified, and a mounting hole is made at the front end, install another grain feeding tooth to the bottom of the grain feeding tooth (1) The front end is inserted into the mounting hole and riveted with the pin shaft. After assembly, the reel can rotate around the pin shaft, so it has the function of stretching and shrinking. The place where the reel needs to be stretched is at the support position of the root of the reel. Guide rails are installed, and no guide rails are installed where the reel teeth do not need to be extended but need to be retracted. It can be used in occasions where the space is limited and the grain needs to be delivered or assisted.

Embodiment 3

[0023] Embodiment 3 is assembled according to the form of above embodiment 1. If the shape of the grain feeding tooth (1) is slightly modified, it is made into a similar bucket shape, and it is installed on the conveying equipment, which can transport heavier objects. And there will be no defects like belt slippage. The conveying equipment of this scheme is durable, can carry a large load, and has a long service life.

Abstract

The invention discloses a semi-feeding combined harvester straw feeding chain, which is composed of a straw feeding tooth in integral enclosed structure, and a roller chain. The straw feeding tooth is directly assembled between an inner chain plate and an outer chain plate of the roller chain. Under simultaneous pressing of the inner and outer chain plates, the straw feeding tooth in integral enclosed structure can distribute various impact resistances during straw delivery and threshing process to the entire chain, avoid stress concentration at position of a riveting hole of the straw feeding tooth, and protect the chain. The straw feeding chain is durable and breakage-resistant, and simple and convenient in maintenance.

Description

technical field [0001] The invention relates to a chain structure of a grain feeding chain used for a half-feed combine harvester to transport rice stalks during harvesting operations. Background technique [0002] The chain is a conveying device widely used in semi-feed combine harvesters. At present, the grain feeding chain is usually composed of a single-piece grain feeding tooth and a roller chain, and the single-piece grain feeding tooth is directly riveted on one side of the roller chain. During the working process of the harvester, the grain delivery chain needs to transport rice stalks that are sometimes dense and sometimes sparse. Therefore, in the process of conveying the rice stalks, it is not only subjected to the horizontal impact resistance of the rice stalks, but also the upward impact thrust of the rice stalks during the threshing process. , the final impact load is all concentrated on the riveting hole of the grain feeding tooth, forming an impact stress. ...
