Description

A kind of fructus arctii spacing on-demand device

Technical field

The utility model relates to fructus arctii planting technology field more particularly to a kind of fructus arctii spacing on-demand devices.

Background technique

Fructus arctii, also known as: reality, Great Burdock Achene, Fructus Arctii are disliked, seminal propagation is mainly used, type of seeding has drilling and bunch planting two Kind, drilling ditches on the ground, then by seed uniform broadcasting in ditch, earthing；Bunch planting is then that bunch planting kind is opened by seeding row spacing, often Bunch planting 4-6, earthing.And during bunch planting, traditional method is sowed by manually opening cave, and this mode is not only Waste of manpower, while will cause that the distance between strain and strain are unbalanced, cause the growing way of plant unbalanced.

An existing patent name is " a kind of plant strain away from spacing device ", in Publication No. " CN207185141U " State's utility model patent, spacing is achieved the purpose that by the spacing cone being distributed on stitch marker, and another patent name is " one Kind test transplanting mulch duplicate rows spacing device ", the Chinese utility model patent of Publication No. " CN207118273U " passes through setting Idler wheel is disposed with the mode of spacing item to achieve the purpose that spacing on idler wheel, and two existing patent documents are utilized in rolling The outer surface of wheel is arranged projection, and the mode that projection is left a trace on the ground during rolling reaches the mesh of spacing 's.But due to the defect of the structure, projection outside idler wheel often small volume is set, not so influences whether idler wheel It rolls, therefore the label that will lead on the ground is unobvious, can not find spacing label, during subsequent easily so as to cause mistake Go the effect of spacing.

Utility model content

In view of this, the purpose of the utility model is to provide a kind of fructus arctii spacing on-demand devices, by inside protective shell Spacing mechanism is set, can achieve the effect that spacing, will not influence normal operation, while the label left is more apparent, one Determine to avoid the case where can not find label in the follow-up process generation in degree.

The utility model solves above-mentioned technical problem by following technological means:

A kind of fructus arctii spacing on-demand device, including protective shell, handle and spacing mechanism, the spacing mechanism are installed on protection In shell, the spacing mechanism includes shaft, and the both ends of the shaft are threaded through on the opposite two sidewalls of protective shell, and in protective shell It is rotatablely connected outside with handle, idler wheel, transmission gear and driving wheel is fixedly installed in the shaft, between the idler wheel and shaft Rolling bearing is installed, several connecting rods, fixed peace on the inner wall of the idler wheel are installed between the idler wheel and rolling bearing Equipped with gear ring, the transmission gear and gear ring are meshed, and protrusion, the spacing are provided in the circumferential exterior surface of the driving wheel Mechanism further includes the distance plate being vertically installed in protective shell, and the distance plate is integrally formed with teeth on the end face of driving wheel Item, the protrusion is integrally formed with the gear teeth on the end face of rack gear, and the gear teeth and rack gear are meshed, and the protective shell is close The position on ground offers opening.

Utility model by adopting the above technical scheme, when in use, operator hold handle, and pushing rolling wheels roll forward Dynamic, during rolling, idler wheel drives the gear ring on inner wall to rotate together, and gear ring and transmission gear are meshed, therefore tooth Circle band nutating gear drives shaft that driving wheel is driven to rotate together again, and when driving wheel rotates, the protrusion on driving wheel and then turns Dynamic, the gear teeth in protrusion can be meshed with the rack gear on distance plate in the course of rotation, and distance plate is driven to move downward, thus Leave trace on the ground, then when the gear teeth are detached from out of rack gear, distance plate retraction, until next time protrusion on the gear teeth and Rack gear is meshed, and positioning plate is driven to be moved downwards, achievees the purpose that spacing with this；And in the process for carrying out spacing label It is to drive distance plate to be marked by driving wheel, the rolling of idler wheel will not be had an impact, while can stay on the ground Under relatively deep, clearer, apparent trace, avoid in the follow-up process the case where can not find label generation to a certain extent.

Further, plug connector, the spacing are fixedly installed in the corresponding position of distance plate on the inner wall of the protective shell Plate is actively plugged in plug connector, and the side of the plug connector close to driving wheel offers through slot.By the design of plug connector, one Aspect plays the role of fixing and supporting to distance plate, on the other hand plays effect of contraction to distance plate so that its always along Plug connector is reciprocating, avoids the case where shifting, and ensure that the accuracy of spacing to a certain extent.

Further, the distance plate includes the driver plate being fixedly connected and spacing head, between the driver plate and plug connector It is fixedly connected with multiple reset springs.The design of the structure ensure that distance plate when protrusion is detached from by reset spring Original position can be restored to.

Further, the described one end of spacing head far from driver plate is integrally formed with point.The design of point is so that fixed Trace is more easily left on the ground away from plate, and apparent.

Further, it is also equipped with auxiliary drive motor on the protective shell, the output shaft of the auxiliary drive motor and turns Axis is fixedly connected.The design of the structure, operator can open auxiliary drive motor during use, pass through auxiliary drive Motor drives shaft, and band nutating gear, driving wheel are rotated, and since gear ring and transmission gear are meshed, transmission Gear will drive gear ring and idler wheel driven to be rotated and rolls forward, thus, it is possible to save the body of operator to a certain extent Power reduces labor intensity.

Further, rolling bearing is mounted between the shaft and handle, between shaft and protective shell.Pass through the axis of rolling Hold, on the one hand can reduce shaft and handle, the abrasion between shaft and protective shell contact surface, on the other hand can make using It is more stable, it runs more stable.

The utility model has the beneficial effects that

A kind of fructus arctii spacing on-demand device of the utility model passes through idler wheel band nutating gear, again when in use It drives shaft that driving wheel is driven to rotate together, spacing is reached with this by protrusion on driving wheel and distance plate synergistic effect Purpose will not generate the rolling of idler wheel since the process of spacing label is to drive distance plate to be marked by driving wheel It influences, while can leave relatively deep, clearer, apparent trace on the ground, avoided to a certain extent subsequent The case where can not find label in the process generation.
