Caterpillar water chestnut combine harVester

Abstract

The inVention discloses a caterpillar water chestnut combine harVester, which comprises a chassis, a walking system arranged below the chassis, a digging system arranged in front of the chassis, a two-way Vibration separation system arranged aboVe the chassis, a cleaning system and a hydraulic lifting system arranged behind the chassis, wherein a lifting cross beam welded at the tail end of the digging system is connected with the hydraulic lifting system. The two-way Vibration separation deVice comprises a rear throwing motion and a left and a right sieVe of the water chestnuts, when the water chestnuts perform rear throwing motion on a separation sieVe plate, the rasp rod on the separation sieVe plate can increase the friction force between the water chestnuts and the separation sieVe plate to generate a comb brush action and an impact action on the water chestnuts, when the water chestnuts perform a left and right sieVe motion on the separation sieVe plate, the separation sieVe plate generates a Vibration effect on the water chestnuts. By using the harVester, the work of digging, transporting, separating, cleaning, collecting and binning the like can be completed at one time, the harVesting time of the water chestnuts is greatly shortened, the harVesting efficiency is improVed, the damage of the water chestnuts is small during the harVesting process, and the labor intensityof farmers is reduced.

Description

Technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a crawler-type water chestnut combine harvester. Background technique [0002] Water chestnuts are easy to plant and difficult to harvest, manual excavation efficiency is low, the intensity is high, and the working environment is harsh (water chestnuts are generally harvested after winter, and the weather is cold), which restricts the intensive and large-scale production of water chestnuts. In order to realize the mechanized harvest of water chestnuts, Jiao Zhong et al. (Jiao Zhong, Wang Chengjun, Wang Shuai. A water chestnut excavator [P]. China, 201110112088, 2011-10-05.) designed a water chestnut dry harvesting excavator with wheels A type tractor is powered, excavated by a plow, and a rotary cutting device separates water chestnuts from the soil, and then manually picks them up; Chen Haifeng et al. (Chen Haifeng, Zhang Shixi. Research on the mining mechanism and str...

Problems solved by technology

[0002] Water chestnuts are easy to grow but hard to harvest, manual excavation is inefficient and intensive, and the working environment is harsh (water chestnuts are generally harvested after winter, and the weather is cold), which restricts the intensive and large-scale production of water chestnuts

In order to realize the mechanized harvesting of water chestnuts, Jiao Zhong et al. (Jiao Zhong, Wang Chengjun, Wang Shuai. A kind of water chestnut excavator [P]. China, 201110112088, 2011-10-05.) designed a water chestnut dry-harvesting excavator. A tractor is used as the power to excavate with a plow, and the rotary cutting and crushing device separates the water chestnuts from the soil, and then manually picks them up; Chen Haifeng et al. Carried out research on water chestnut harvesting boats, and designed a paddy field harvester, powered by a boat tractor, using a rotary grid excavation shovel for excavation and at the same time achieving separation through the water knife inside the excavation device; Wang Chuan (Wang Chuan, Liu Hui, Wang Liwei, Wang Wei, Wang Gao. The overall design of the water chestnut harvester [J]. Chinese Journal of Agricultural Mechanization, 2017.) discloses a water chestnut harvester, which is powered by a wheeled tractor and uses a digging shovel to dig out the water chestnuts. The separation of soil and water chestnuts is realized through the separation device and the spraying device; because the water chestnuts are harvested with deep mud feet and high soil viscosity, in the above method, the wheeled tractor sinks deep into the mud feet, the driving wheel of the boat tractor slips seriously, and the sliding resistance of the hull is large. The traction efficiency is low, the separation device mostly adopts vibration separation, and the separation effect needs to be further improved
