Description
Technical field
The utility model relates to agricultural mechanical field, is specifically related to a kind of small harvester crawler attachment.
Background technology
At present, rural area rice cultivation and wheat are extensively promoted mechanical harvesting, because farmland can not be unified in flakes farming, be caused harvest time difference, south to have farmland fritter, field mud depth difference, restrict the operation comformability of large-scale reaper.Small harvester crawler attachment has been broken through large-scale reaper and cannot have been entered the operation bottleneck of rural area harvesting, has advanced the mechanization of harvest operation, has shortened the work cycle, and has allowed people free from heavy manual labor.Be widely used in the crops such as getting wheat, paddy rice, highland barley, crudefiber crop, beans.Change corresponding cutter, load onto upper and lower supporting plate and safe protective cover, can also gather in shrub, herbage, reed and end of the branch, tea place and prune and flower nursery.Gasoline worn by small harvester crawler attachment or diesel is strong and powerful, and convenient and practical, efficiency is high, is easy to carry and the operation of field, field.It is low that this spark ignition engine has noise.The feature such as solemn silence and traveling comfort.Allowing various places people work long hours can not feel fatigue.
Existing small harvester crawler attachment mostly is wheeled driving, exists wheeled drive wheel easily to skid, and the driving of dark mud field is subsided, drive wheel ground contact area is little, the shortcoming of the Complex poor stability operating difficulties that easily inclines.There is Gearbox design difference separately in existing small harvester crawler attachment track propulsion, productive costs is high, and accessory standard degree is poor, maintenance difficult.Caterpillar system design is clumsy, and large with quantity of material, Heavy Weight, can not meet farmland operation and light, the easy and simple to handle requirement of agricultural short-distance transport requirement, has limited the application of caterpillar drive system on small harvester crawler attachment.
Utility model content
The utility model aims to provide a kind of small harvester crawler attachment, this small harvester crawler attachment has overcome prior art defect, by the pedrail mechanism of unique design, avoid the defect of the wheeled and crawler type miniature harvester crawler attachment of prior art, there is scientific structure, the advantage that harvesting efficiency is high.
Small harvester crawler attachment described in the utility model, comprises track propulsion gear, front crawler rack, rear crawler rack, track adjusting wheel, track adjusting wheel adjustment screw rod, track roller, crawler belt; Described track adjusting wheel is provided with two, lays respectively at front and the rear of crawler belt; Described front crawler rack is connected with reaper with rear crawler rack upper end, and lower end is connected with track adjusting wheel, the track roller of front and back respectively, and described track roller is positioned in the middle of former and later two track adjusting wheels; Described track adjusting wheel is adjusted screw rod and is connected with track adjusting wheel and track roller above respectively.
Described reaper main body is connected with rubber belt track driven wheel by change speed gear box, the gearbox linkage of rubber belt track driven wheel and reaper, and transferring power drives crawler belt, and then drives former and later two track adjusting wheels and track roller.
Described crawler belt is rubber belt track, can further strengthen skidproof effect, and effective expendable weight.
Described reaper main body is connected with front crawler rack by hydraulic efficiency gear.
Described actuating device is diesel engine or spark ignition engine; Described traveling gear is pedrail mechanism.
The caterpillar system of the utility model unique design, change speed gear box directly and track propulsion gear interlock, transferring power is to track propulsion gear, and this walking structure is simple, and technical performance is reliable, track area is large, anti-skidding, collapse, make reaper stability strong, simple to operate, be convenient to accessory unified specification, Operation and maintenance are convenient.Crawler belt preferred rubber material, can further increase antiskid capability, and expendable weight, reduces costs.
Caterpillar system universalization skill level of the present utility model is high, cost is low, and antiskid capability is strong, increases with ground area of contact, reduces complete machine and geostatic pressure, improves carrying capacity, simple to operate, easy to maintenance.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view that the small harvester that provides of the utility model embodiment coordinates crawler attachment.
Sequence number in Fig. 1 and each several part structure and title are as follows:
1-track propulsion gear, crawler rack before 2-, crawler rack after 3-, 4-track adjusting wheel, 5-track adjusting wheel is adjusted screw rod, 6-track roller, 7-crawler belt, 8-change speed gear box, 9-reaper main body, 10-hydraulic efficiency gear.
The specific embodiment
Below in conjunction with accompanying drawing, a kind of embodiment of the present utility model is described:
As shown in Figure 1, described small harvester crawler attachment comprises track propulsion gear 1, front crawler rack 2, rear crawler rack 3, track adjusting wheel 4, track adjusting wheel adjustment screw rod 5, track roller 6, crawler belt 7; Described track adjusting wheel 4 is provided with two, lays respectively at front and the rear of crawler belt; Described front crawler rack 2 is connected with reaper with rear crawler rack 3 upper ends, and lower end is connected with track adjusting wheel 4, the track roller 6 of front and back respectively, and described track roller 6 is positioned in the middle of former and later two track adjusting wheels 4; Described track adjusting wheel is adjusted screw rod 5 and is connected with track adjusting wheel 4 and track roller 6 above respectively.
Described reaper main body 9 is connected with rubber belt track driven wheel 1 by change speed gear box 8, change speed gear box 8 interlocks of rubber belt track driven wheel 1 and reaper, and transferring power drives crawler belt 7, and then drives former and later two track adjusting wheels 4 and track roller 6.
Described crawler belt 7 is rubber belt track, can further strengthen skidproof effect, and effective expendable weight.
Described reaper main body 9 is connected with front crawler rack 2 by hydraulic efficiency gear 10.
Small harvester crawler attachment of the present utility model is work like this:
Start small harvester, power is passed to track propulsion gear 1 by change speed gear box, and track propulsion gear 1 drives crawler belt 7, and crawler belt 7 is rotated, and crawler belt 7 drives former and later two track adjusting wheels 4 and track roller 6, and reaper is advanced.The common composition supporting mechanism of front crawler rack 2, rear crawler rack 3 and track roller 6, supports reaper; Track adjusting wheel is adjusted screw rod 5 for adjusting the distance between former and later two track adjusting wheels 4, keeps crawler belt 7 anxieties, and crawler belt 7 can not come off because of relaxing.
