Description

Technical Field

[0001] The present invention relates to the field of agricultural machinery, and more specifically, to a harvesting platform and a harvester. Background Art

[0002] Rice belongs to the genus Oryza of the Poaceae family and is an extremely ancient crop. According to archaeological discoveries, the history of rice cultivation in my country is at least about 7,000 years. There are two types of cultivated rice in the world, namely Asian cultivated rice and African cultivated rice. Among them, Asian cultivated rice has a large planting area and is distributed throughout rice-growing areas around the world. It is called common cultivated rice. The rice panicle is composed of many spikelets. The rice grains are called rice grains, which are called rice or rice after being husked. In addition to being edible, rice can also be used to make wine and as the main raw material for sugar production. Rice husks and rice stalks also have many uses. At present, China's annual grain output has reached 500 million tons, and China has become one of the world's major grain-growing countries.

[0003] In order to reduce the intensity of manual labor and increase the harvesting speed of grain, my country has gradually increased the research on agricultural mechanization, and the level of agricultural machinery has been rapidly developed. In the prior art, many areas in my country have begun to use harvesters for automatic harvesting of crops such as rice, and harvesters are often equipped with special headers to harvest the stems of rice and rape from the fields, and then input them to the rear of the harvester through a conveyor trough for threshing and storage. In actual operation, since rice is a stalk crop and rice grains are not easy to fall off from the stalks, it is relatively easy to feed the conveyor trough through a conventional header, and there is no need to worry about the grains falling into the header due to collision during feeding. However, when harvesting small-grain crops such as rapeseed, rapeseed is extremely easy to fall off from the stalks and fall into the header, and due to the limitations of the existing harvester header structure design, it is difficult for the header to feed rapeseed into the conveyor trough, resulting in a large amount of rapeseed remaining in the header, which is very likely to cause unnecessary losses. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a harvesting platform, which, through its structural design, can efficiently realize the transmission and feeding of crops such as rice and rapeseed, and effectively avoid unnecessary losses.

[0005] A cutting platform comprises a bin body, a cutting knife is arranged in front of the bin body, a discharge port for material discharge is arranged at the rear of the bin body, a rotatable auger shaft is arranged in the inner cavity of the bin body, a mounting sleeve is arranged on the outer wall of the auger shaft, a first guide hole and a second guide hole arranged at intervals are arranged on the mounting sleeve, a slide groove is arranged through the first guide hole and the second guide hole, a first shifting rod is inserted in the first guide hole, a second shifting rod is inserted in the second guide hole, a shifting plate is clamped between the first shifting rod and the second shifting rod, the bottom of the shifting plate is opposite to the slide groove, and the shifting plate is used to shift the material toward the discharge port.

[0006] Preferably, the paddle is arranged directly in front of the discharge port.

[0007] Preferably, at least two paddles are provided and the paddles are arranged in a ring shape on the outer cylindrical surface of the auger shaft.

[0008] Preferably, the auger shaft is a hollow auger shaft.

[0009] Preferably, the inner cavity of the hollow auger shaft is provided with an eccentric fixed shaft, and the outer cavity of the eccentric fixed shaft is provided with a rotating sleeve, the first lever and the second lever penetrate the side wall of the hollow auger shaft and are connected to the rotating sleeve, and the lever plate is slidably installed between the first lever and the second lever, wherein when the hollow auger shaft rotates, the eccentric fixed shaft remains stationary, and the rotating sleeve rotates driven by the first lever and the second lever, and the lever plate repeatedly enters and exits between the inner cavity of the hollow auger shaft and the outside of the hollow auger shaft from the slide groove.

[0010] Preferably, a maintenance port is provided on the side wall of the hollow auger shaft, and a sealing door is provided on the maintenance port.

[0011] Preferably, a spiral stirring blade is arranged outside the auger shaft.

[0012] Preferably, the mounting sleeve is detachably connected to the outer wall of the auger shaft by bolts.

[0013] The present invention further provides a harvester, on which any one of the above-mentioned harvesting platforms is installed.

[0014] The beneficial effect of the present invention is that when the harvesting table and the harvester provided by the present invention are used, since the first guide hole is inserted with the first lever, the second guide hole is inserted with the second lever, and a lever plate is provided between the first lever and the second lever, the stems of materials such as rice and rapeseed can be moved by the first lever, the second lever and the lever plate, and the rapeseed and other fine materials dropped in the bin can be moved toward the discharge port by the lever plate to avoid rapeseed and other fine materials remaining in the harvesting table, thereby realizing the efficient transmission and feeding of crops such as rice and rapeseed and effectively avoiding unnecessary losses.
