Abstract
The utility model discloses a kind of wheat stubble choppers, comprising: rack, gearbox is connected in rack, gearbox connects transmission device, the cutter shaft on the power output connection right side of the transmission device, the cutter shaft in another power output connection left side of transmission device, and have interval between left and right two cutter shafts, blade is flexibly connected on two cutter shafts.It passes through the blade being flexibly connected, it is gone to by rotary knife axis and throws blade away, to use blade cut wheat stubble, since blade is not rigidly connected with rotary knife axis, when blade touches hard object, blade is made on the one hand to have the buffering of certain distance, another aspect blade is streaked from hard object, blade be not easy it is directly bad by hard object top, greatly reduce maintenance blade probability.
Description
Technical field
The utility model relates to a kind of agricultural machinery more particularly to a kind of wheat stubble choppers for being hardly damaged blade.
Background technique
At present in wheat harvesting process, harvester is mostly used to carry out wheat harvesting, be effectively saved it is artificial and
Reduce labor intensity.But the wheat stubble left after harvester harvesting is higher, and existing rotary cultivator is used to carry out wheat stubble also
During field, it is be easy to cause the damage of Rotary Tiller Blade, greatly reduces working efficiency.Secondly, existing rotary cultivator is not
Be adapted to wheat and other crops such as: peanut, capsicum, interplanting corn plot, its of interplanting is easily damaged in rotary tillage
His crops.
Utility model content
The purpose of the utility model is to provide a kind of wheat stubble chopper, with overcome existing for currently available technology it is above-mentioned not
Foot, does not easily cause the damage of blade.
The utility model passes through as flowering structure is realized comprising: rack connects gearbox in rack, and gearbox connects
Transmission device, the cutter shaft on the power output connection right side of the transmission device, another power output of transmission device connect
The cutter shaft in left side is connect, and has interval between left and right two cutter shafts, is flexibly connected blade on two cutter shafts.
Tool apron is connected on the cutter shaft, tool apron is equipped with connecting hole, passes through blade shaft in connecting hole, blade shaft also extends through knife
The perforation of on piece, blade and blade between centers do not have tie point.
The blade is made of two points of blades, and two points of blades distinguish outward bending.
The cutter shaft is externally provided with Earthguard cover.
Hinged grading planker after the Earthguard cover.
The transmission device is belt transmission, gear drive or chain and sprocket driving device.
The utility model is rotated by cutter shaft by the blade being flexibly connected and throws blade away, thus with blade cut wheat
Stubble, when blade touches hard object, makes blade on the one hand have the buffering of certain distance since blade is not rigidly connected with cutter shaft,
Another aspect blade is streaked from hard object, blade be not easy it is directly bad by hard object top, greatly reduce maintenance blade probability.Together
When, due to being to be flexibly connected the replacing construction for making the replacing construction of blade be less than the mode that is fixedly connected, facilitate the maintenance of equipment.
Secondly, two groups of cutter shafts be provided separately for interplanting crops reserved space, do not allow when carrying out the operation of wheat stubble returning to the field easy damaged its
The crops that he interplants.
Detailed description of the invention
Invention is described in further detail below according to attached drawing.
Fig. 1 is the structural schematic diagram of the utility model embodiment, and the right view of Fig. 2, Fig. 3 is that cutter shaft and blade are horizontal positioned
When structural schematic diagram.
Specific embodiment
The utility model embodiment as shown in Figure 1, Figure 2 and Figure 3 includes: rack 1, connects gearbox 2 in rack 1, becomes
Fast case 3 connects transmission device 10, the cutter shaft 3 on the power output connection right side of the transmission device, transmission device it is another
The cutter shaft in a power output connection left side, and have interval between left and right two cutter shafts, blade 6 and two are flexibly connected on two cutter shafts
Grade driven wheel.Tool apron 4 is all connected on two cutter shafts, tool apron is equipped with connecting hole, blade shaft 5 is passed through in connecting hole, blade shaft 5 is also
Perforation on blade 6, without tie point between blade 6 and blade shaft 5.The blade 6 is made of two points of blades, and two
Blade is divided to distinguish outward bending.It is respectively equipped with Earthguard cover 7 on left and right two cutter shafts 5, and hinged grading drags after Earthguard cover 7
Plate 8.Transmission device 10 includes: axis, and the both ends of axis are separately connected the first from left grade driven wheel and right level-one driven wheel, in axis
Grade connection principal and subordinate wheel.The power that gearbox obtains is passed to principal and subordinate wheel by belt by transmission device 10, and principal and subordinate wheel is logical
It crosses axis and imparts power to the first from left grade driven wheel and right level-one driven wheel, the first from left grade driven wheel is imparted power to by belt
The second level driven wheel in left side, and right level-one driven wheel imparts power to the second level driven wheel on right side by belt simultaneously.This reality
It is connected on tractor with novel by connecting rod 9, then by being connected by power in gearbox 2 on tractor, passes through tractor
Engine provides power for the utility model.When transmission device band movable arbor 3 rotates, exist with the blade 6 that cutter shaft 3 is flexibly connected
It has been got rid of under the action of inertia, has made blade 6 perpendicular to cutter shaft 3, to cut soil.When blade touches hard object,
It blade and pops up and will not be collided with hard object fierceness, generate biggish stress to make its deformed damaged.
Chain conveyer or gear transmission mode also can be used in the transmission device of the utility model, only need to be by the power on tractor
Pass to cutter shaft.
