Abstract
The utility model discloses a kind of cross type weeder, drives the two rows of rake teeths in front and latter one roller, the synchronous weeding of the cross type laterally and longitudinally combined by a central turnplate.There is a crankshaft on the turntable of the utility model, passes through a connecting rod on crankshaft and pull a longitudinal rack, rack gear is engaged with a gear, two horizontal tooth bars or so are driven to move towards, the tooth harrow for respectively having a row vertical below two horizontal tooth bars, left and right are stirred, and tooth harrow laterally chops weeds root off.Turntable back is engaged with an angular wheel, drives two actives and two driven gears by one section of coaxial threaded, has a roller among driven gear, and a few row's rake teeths on roller carry out longitudinal root out to weeds.
Description
Technical field
The utility model relates to a kind of cross type weeders, more particularly to one kind to pass through the laterally and longitudinally same luck of rake teeth
It is dynamic, carry out the cross type weeder that weeds roots out work.
Background technique
In the agricultural production of vast third world countries, peasant carries out field weeding, mainly or based on craft, or
Person uses the serious herbicide for polluting environment and soil.In a small number of weeding agricultural machinery, typically single lateral machinery is removed
Grass, and machines cumbersome, this patent product pass through the method laterally and longitudinally combined, carry out dual weeding with machine power.
Summary of the invention
The purpose of this utility model is to provide a kind of weeding by machine's machine for doing power by rechargeable battery or Mini Diesel Engine,
It is moved simultaneously by lateral rake teeth and longitudinal roller tooth, work is extracted and rooted out to the weeds for carrying out cross type.
To achieve the above object, the utility model uses following technical scheme:
This weeder has the oblique gear of turntable to do centre-drive device, there is a crankshaft above the oblique gear of turntable,
A connecting rod is connected on crankshaft, the connecting rod other end is connect with a toothed rack, a rack pinion rotation is driven, with rack pinion
A coaxial toothrow gear drives two opposite toothrow rack gears or so to move towards again, respectively has one below two toothrow rack gears
Vertical metal tooth harrow is arranged, toothrow rack gear moves towards, and two rows of tooth harrows just stir by left and right, so that weeds root laterally be chopped off.
Further: the helical teeth on turntable twill gear is intermeshed with an angular wheel, coaxial with tapered gear
The other end has one section of screw thread, by engaging with the circular gear of a transverse direction, drives a lateral shaft, then drive lateral shaft
The driving gear at both ends rotates, and the driving gear of lateral both ends of the shaft is engaged with two driven gears at discaling roll both ends respectively, most
Discaling roll rotation is driven afterwards.
Further: having several row's contrates on discaling roll, when discaling roll rotates, these roller tooths can longitudinally root out weeds root
And it transfers to.
Further: the crankshaft upper end on the turntable of this weeder drives turntable for connecting motor or Mini Diesel Engine
When loxodont wheel rotates, the roller tooth at the toothrow in front and rear works simultaneously, weeds and root, through weeder laterally with it is vertical
It is rooted out to dual, just improves efficiency.
Further: the shape of this weeder can be remote-controlled robot, pass through the wireless receiving module on fuselage, operation
Stabilization and direction of the person with remote control control machine;A handrail can also be added, by operation vehicle hold handle carry out stablize with
Direction to control.
The beneficial effects of the utility model are: having rechargeable battery or Mini Diesel Engine, turntable is driven, before machine
Two rows of tooth harrows, which laterally draw to weeds, to be dialled and sliding trackle, while by a few row's roller tooths on the subsequent roller of machine, to weeds into
Longitudinal broadcast of row is rooted out, and the dead angle there will be no weeds existence, the nutrient that can be effectively protected crops are not snatched away by weeds in this way.
Detailed description of the invention
Fig. 1 is each position connection structure diagram;
Fig. 2 is complete machine structure figure;
Appended drawing reference:
1 active rack gear, 2 rake teeth
3 toothrow, 4 rack pinion
5 toothrow gear, 6 connecting rod
The oblique gear of 7 crankshaft, 8 turntable
The tapered gear of 9 crankshaft connecting rod axle 10
11 circular gear, 12 driving gear
The lateral shaft of 13 screw thread 14

Specific embodiment
Many details are elaborated in following specific descriptions in order to fully understand the utility model, but this reality
It can also be realized using other different from the other modes of this description with novel, therefore, the protection scope of the utility model is simultaneously
It is not limited by the specific embodiments disclosed below.
As Figure 1-Figure 2,
This weeder has the oblique gear 8 of a turntable to do centre-drive device, and the oblique gear 8 of turntable has a crankshaft above
7, a connecting rod 6 is connected on crankshaft 7, and the connecting rod other end is connect with a toothed rack 1, drives a rack pinion 4 to rotate, with tooth
A coaxial toothrow gear 5 of bar gear 4 drives two opposite toothrow rack gears 3 or so to move towards again, two toothrow rack gears 3
The metal tooth harrow 2 that lower section respectively has a row vertical, toothrow rack gear 3 move towards, and two rows of tooth harrows 2 are stirred with regard to left and right, thus by weeds
It laterally chops off root.
Helical teeth on turntable twill gear 8 is intermeshed with angular wheel 10, with coaxial another of tapered gear 10
There is one section of screw thread 13 at end, is engaged by the circular gear 11 with a transverse direction, drives a lateral shaft 14, then drive transverse direction
The driving gear 12 at 14 both ends of shaft rotates, the driving gear 12 at lateral 11 both ends of shaft two with 16 both ends of discaling roll respectively
Driven gear 15 engages, and finally discaling roll 16 is driven to rotate.
There are several row's contrates 17 on discaling roll 16, when discaling roll 16 rotates, these roller tooths can longitudinally root out weeds root simultaneously
It transfers to.
7 upper end of crankshaft on this weeder turntable 8 drives turntable twill gear 8 for connecting motor or Mini Diesel Engine
When rotation, the toothrow 2 in front and the roller tooth 17 at rear work simultaneously, and weeds and root are laterally and longitudinally double through weeder
It roots out again, just improves efficiency.
The shape of this weeder can be remote-controlled robot, pass through the wireless receiving module on fuselage, operator's remote control
Device controls stabilization and the direction of machine;A handrail can also be added, handle is held by operation vehicle and carries out stable and direction to control.
The fuselage size of this weeder fits into the spacing range of crops in the ground of field, can be in agriculture because light
It is laterally and longitudinally shuttled between crop.
This weeder is due to laterally and longitudinally rooting out grass roots, ultrahigh in efficiency, can also play the work that shallow-layer loosens the soil
With.
