Embodiment Construction

[0031] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:

[0032] Such as figure 1 As shown, a combined harvester grain flow detection device based on centrifugal force analysis according to the present invention includes a clean grain elevator 1, and a chain hoist 2 is arranged inside the clean grain elevator 1. The chain hoist 2 includes a driving gear 4 installed in the housing 3. A chain 5 is installed on the driving gear 4. A plurality of scrapers 6 are mounted equidistantly on the chain 5. The driving gear 4 drives the scrapers 6 on the chain 5. Plate 6 makes an upward movement. Here, the scraper 6 is used to carry the grain, and it is fixedly installed on the chain 5 , that is, the scraper 6 faces upward on one side of the chain 5 and downward on the other side of the chain 5 . The p...

Abstract

The invention relates to a combine harvester grain flow detection device based on centrifugal force analysis and a detection method thereof. Compared with the prior art, the defect that a grain flow measurement manner cannot meet actual use requirements easily is overcome. The position, located above a driving gear, of a shell is in a circular arc shape, the circle center of the circular arc and the circle center of the driving gear are the same point, a centrifugal force collecting window is formed in the shell, and the centrifugal force collecting window is located in the tangential direction of the installation position of a scraper when the scraper moves to the top end of the driving gear. A reference force impulse plate and a measuring force impact plate are installed on a reference force sensor and a measuring force sensor through rigid beams respectively, the measuring force impact plate is located in the centrifugal force collecting window, and the reference force impulse plate is located outside the shell. Grain flow is detected in a centrifugal force manner, the grain flow is measured through circular motion of a chain elevator, the detection precision is high, and the complexity is low.

Description

technical field [0001] The invention relates to the technical field of grain flow detection, in particular to a combine harvester grain flow detection device based on centrifugal force analysis and a detection method thereof. Background technique [0002] Precision agriculture is a precision farming technology for field crop production mainly based on 3S spatial information technology and crop production management decision support technology. Installing a grain yield monitoring system on a combine harvester to obtain crop yield distribution information and establish a farmland yield spatial distribution map is an important part of the implementation of precision agriculture. The core component of the grain yield monitoring system is the grain flow detection device. The grain flow detection methods mainly include photoelectric volumetric type, radiation type and impulse type. Among them, the photoelectric probe is easily polluted, the radiation probe is harmful to the human...
