A scraper-suction grain collecting machine

Abstract

The invention relates to a scraping and suction type grain collecting machine. The machine is provided with a frame-shaped rack, and the top of the rack is also provided with bearing mounting bases which are arranged front and back side by side. The bearing mounting bases are rotationally connected with a box body of an inclined scraper type grain collecting box through transmission rotating shafts, a power machine is arranged in the middle of a frame of the rack, and the output end of the power machine is in transmission connection with a belt wheel. A wheel shaft of the belt wheel is in transmission linkage with the ends of the transmission rotating shafts through a driving chain, the bottom of the scraper type grain collecting box is provided with an air suction type grain collecting box in the length direction of the box body, and an air draft duct is arranged on the outer side wall of the upper end of the box body of the air suction type grain collecting box. A rotary four-blade partition board is further arranged in a grain unloading bucket, a centrifugal fan is further arranged in the rack, and the centrifugal fan communicates with the air draft duct through an air duct. Thegrain collecting machine is novel and ingenious in structural design, grains are collected completely, operation is carried out automatically, and the grain collecting machine has good actual application and popularization value.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery and equipment, in particular to a scraping and suction grain collecting machine. Background technique [0002] At present, various granular crops must be dried in the sun after being harvested, and then packed and stored in warehouses. The traditional method is to pack the crops by hand, that is, to manually pack the crops into the packaging bags with a shovel or shovel, and then put them into the warehouse. This is not only labor-intensive, but also very low in efficiency of harvesting crops. Therefore, it is very necessary to design a grain harvester that can automatically harvest crops and fill bags. Nowadays, a scraper type high-speed grain harvester has been designed (see the patent document of application number 201210191058.X) and a new type of grain harvester (patent number ZL201410482664.6), but these two grain harvesters are due to their own structure The defect is that ...

Nowadays, a scraper type high-speed grain harvester has been designed (see the patent document of application number 201210191058.X) and a new type of grain harvester (patent number ZL201410482664.6), but these two grain harvesters are due to their own structure The defect is that it is difficult to automatically collect large-grain grains or grains with a relatively large drying thickness or stacked grains, or even block the grain transport box, or the collection of granular grains is not thorough when collecting grains. Residues on the drying field need to be manually cleaned for further grain harvesting, which virtually increases labor costs and labor intensity, and also affects grain harvesting efficiency
