Energy-saving double-row cassava harvester
Technical field
The utility model relates to a kind of agricultural machinery of gathering in the crops underground root crop, specifically a kind of energy-saving double-row cassava harvester.
Background technology
Cassava results product mainly is underground piece root.Tapioca root harvest yield is large, China's overwhelming majority area is by manual work basically at present, adopt hand or pull out simply that the potato instrument pulls out and the double operating type that digs with a hoe, cause the tapioca root results to become the operation that labour intensity is maximum in the current cassava production process, appropriation of labour power is maximum, and manual work productivity ratio is low, operating cost is high, tapioca root is larger in addition, distribution under the earth's surface is irregular again, and meat is crisp, thereby cause the breakage of piece root also large, particularly then can cause the larger loss of piece root and damage to the larger soil of viscosity.
In addition, also there is the small part area in China after manually striking off cane first, adopts animal power or loads onto the colter that does not have plough mouldboard at tractor, with the stubble cleaner pine of piece root both sides, manually is aided with and pulls out or dig first.This half artificial half animal power or half artificial semimechanized harvesting approach, its production efficiency is still low.
And mechanized harvest can not only be enhanced productivity, reduce labor intensity, reduce production costs, the results quality also improves a lot than artificial results, its broken potato, hinder that though potato and broken skin rate change with soil regime and different, under identical conditions all well below manually.But the research of China's tapioca root harvester tool only is in starting and experimental stage at present, does not have ripe type on the market.The potato harvester that in January, 2009, Guangxi Wuming County Agricultural Machinery Bureau, Wuming County agricultural machinery popularization station, Guangxi, Guangxi Agricultural Mechanization Technology Center for Popularization adopted Zhengzhou Shanhe Machinery Manufacturing Co.,Ltd to produce improves has developed 4UM-1600 type cassava harvester, 804 type tractors are power to this machine take Tianjin, fabric width 1.6 m, working depth 30 cm once gather in the crops two ridge piece roots.But huge soil and piece root separator cause the facility load heavy, and resistance is large, thereby productivity ratio is low, and operating cost is high, and its productivity ratio is 3 mu/h only, and the results cost reaches 60 yuan/mu.2008 the end of the year Institute of Farming Machinery under Chinese Academy of Agricultural Mechanization Sciences and the bright standing grain agricultural science and technology in Nanning Co., Ltd unite the Brazilian 4MU-2 type cassava harvester of introduction, it is comprised of a V-arrangement blade that becomes 72 ° of angles, pole, termination, disk soil cutter, frame etc.The V-arrangement blade is installed on the pole, and pole is played fixed blade on the one hand, then is with V-arrangement blade left and right sides sword separately on the other hand, and its left and right sides sword is long 96 cm, wide 10 cm all.Before the operation, need the cassava cane is overhead cut off more than 30 cm and walks clearly, during operation, in the middle of the V-arrangement blade and be fixed on termination on the pole and the disk soil cutter walking of front is furrow between two row cassavas, the left and right sides sword of V-arrangement blade passes through from the tapioca root bottom on left side and right side respectively along direction of advance, and left and right sides sword is respectively gathered in the crops the ridge piece root in the potato ground.But because V-arrangement blade left and right sides sword is respectively gathered in the crops a ridge piece root, so left and right sides sword length is large, cause that facility loads is heavy, intensity is low, thus operating cost is high, productivity ratio is low, adaptability not by force, the facility dependability is poor.This machine also is in the test improvement at present, does not have greater advance.
Summary of the invention
In order to overcome above-mentioned deficiency, the purpose of this utility model is to provide a kind of can carry out tapioca root results and loosing soil integration of operation and energy consumption is low, reliable good, the few energy-saving double-row cassava harvester of piece root loss damage of high productivity, use.
To achieve these goals, the technical solution adopted in the utility model is:
Energy-saving double-row cassava harvester, include the lifting traction component that is hinged on the car body, be fixed on the pull bar on the car body, frame and perching knife assembly, the suppending hole seat that promotes traction component and frame front end is hinged, on pull bar and the frame to be connected long slab hinged, it is characterized in that: described perching knife assembly is by at least two support columns, a plurality of teeth that bury, playing potato plate and extension board consists of, wherein at least two support columns are spaced apart side by side, the upper end of each support column is fixed on the bottom of the rear girder of frame, the plate face of described potato plate is welded on the bottom of all support columns, plays the potato plate horizontal by 21 °~28 ° angles; A plurality of removable spaces of teeth of burying have been distributed in the front side of potato plate, and extension board has been located at the rear side of potato plate.
Described support column is provided with three, the tooth that buries is provided with five, potato plates and is provided with one, extension board and is provided with two.
Described lifting traction component is to be made of lift arm, connecting rod, draw bar, one end and the car body of draw bar are hinged, the suppending hole seat of the other end and frame front end is hinged, the lift arm that power set described and on the car body link to each other and an end of connecting rod are hinged, and the other end of connecting rod is fixed on the middle part of the body of rod of draw bar.
Described pull bar and connecting rod are the expansion links that can carry out length adjustment.
Described potato plate is horizontal by 25 ° of angles.
The beneficial effects of the utility model: the machine prodigiosin carries out the integration of operation of tapioca root results and loosing soil.The potato front edge of board is provided with the tooth that buries, the rear end is provided with extension board, not only helps to bury, and by extension board the piece root is further separated with soil owing to rise.Tooth is through assay optimization owing to bury, and resistance is little, and facility operation oil consumption is low.The interval of column is reasonable, and can adapt to line-spacing is the cassava ground of 0.8m-1m.
