Abstract

The utility model relates to a miniature rotary cultivator for agriculture. The miniature rotary cultivator for agriculture uses a gasoline engine of a knapsack sprayer as a power device, and the soil cultivating depth of the miniature rotary cultivator for agriculture can be adjusted by the relative height of an attaching tooth 12 and a cross rod 28. The miniature rotary cultivator for agriculture can simultaneously realize the functions of furrowing, seeding or fertilizing, scraping, and compacting in tillage, and is suitable for farm field, greenhouses, orchards, and forest farms.

Description

The small farm rotovator

The utility model relates to a kind of small farm rotovator.

Now the polytype rotovator that uses in the farmland all by diesel engine as power, diesel engine can not be done its in addition and use admittedly extremely on frame.These rotovators are big except that weight, the complex structure, also exist can not directly promote after flame-out, can not adjust the rake teeth embedded depth on ground, rake teeth needs deficiencies such as interim installation.In addition, the rake teeth of these rotovators is mounted in the both sides of rotating shaft, the position, gap that the centre is left always plough less than, also to pass through the manpower otherwise processed.

The purpose of this utility model is exactly for overcoming the deficiency described in the above-mentioned background technology, and a kind of novel rotovator of simple in structure, power section dismounting at any time is provided.

To achieve these goals, the utility model proposes the corresponding techniques solution:

Its principal character of this rotovator is that the power machine output shaft end that is connected with frame has and starts wheel, is fixed with flying wheel on the main shaft of belt pulley, and mentioning on the elevating lever cooperates with the cross bar of frame.Said engine is a petrol engine.Be flexible connection between elevating lever and the carriage and between carriage and the protective cover.Between elevating lever and protective cover, be connected with extension spring.The clutch handle that is positioned on the handle links to each other with the decelerator of gearbox by chain cable.

Fig. 1: structural representation of the present utility model.

The left view of Fig. 2: Fig. 1.

Below with reference to accompanying drawing structure of the present utility model is done an explanation.

As shown in Figure 1 and Figure 2, the utility model mainly is by frame 2, power set 3, gearbox 7, handle 11, has rotary tillage wheel 22, decelerator 26, the flying wheel 6 of mentioning 12 elevating lever 13, front-wheel 1, roller 17, having rake teeth 21, the protective cover 18 that is connected with clean-up scraper etc. and constitute.Wherein, power set 3 are connected and fixed by screw and frame 2, and said power set are the gasoline engine of used Mount Taishan 18 type knapsack sprayers.Gearbox 7 is fixed on the frame 2, has decelerator 26 and driving wheel 27 in the gearbox 7.The output axle head of power set 3 is provided with one and starts to take turns 4, start to take turns 4 and belt pulley 25 between have driving-belt 5, belt pulley 25 and flying wheel 6 and speed changer 26 coaxial installations.The rotary tillage wheel 22 that has rake teeth 21 is positioned at the middle part of front-wheel 1 rear side, takes turns 22 coaxial mounted driven pulleys 20 with rotary tillage and is connected with driving wheel 27 by chain 23, has limiting plate 24 in the front of rotary tillage wheel 22, and rear side is provided with colter 19, and protective cover 18 is fixing with frame 2.But roller 17 is connected with the carriage 16 that circumference rotates, and this carriage 16 is connected with protective cover 18 and elevating lever 13 live axles again.Elevating lever 13 tops are provided with mentions 12, and this mentions that 12 can cooperate with the cross bar 28 on the handle 11.Clutch handle 9 is installed on the handle 11, and chain cable 8 is connected between decelerator 26 and the clutch handle 9.One funnel 10 that holds seed or fertilizer also can be installed on handle 11, and these funnel 10 bottoms are connected with carrier pipe 14 again, and an end one of carrier pipe 14 passes straight through to colter 19 places.Between elevating lever 13 and protective cover 18, also be provided with an extension spring 15.

This rotovator needed and will pull down and be screwed on frame 2 as the gasoline engine of the Mount Taishan 18 type knapsack sprayers of power set 3 before using, again driving-belt 5 is connected start to take turns 4 and belt pulley 25 on.Pulling starts to take turns 4 to be lighted power set 3 to start, promptly produce power.Rotate simultaneously by driving-belt 5 drive belt pulleys 25 and decelerator 26, drive 22 actions of rotary tillages wheel by chain 23 again.22 circumference rotate and drive rake teeth 21 is digged downwards because rotary tillage is taken turns, and advance forward so the reaction force that produces can promote whole rotovator fully.The embedded depth of rake teeth 21 can be by mentioning the 12 relative position realization adjustment at cross bar 28, to adapt to the needs of different places and growing different crops.After rake teeth 21 was ploughed soil, just plough immediately and open a ditch dug with a plow by colter 19, seed or fertilizer in the funnel 10 fall in the ditch dug with a plow by carrier pipe 14 thereupon, again by the clean-up scraper that is connected with protective cover 18 strickling of will loosening the soil, and seed or fertilizer are pressed in the ditch dug with a plow, then again by roller 17 compacting of will loosening the soil.

If when farming, need stop temporarily, can spur clutch handle 9, and make decelerator 26 brakings by chain cable 8.During use, the operator only need hand handle 11 and slightly to pressing down, can carry out farming, laborsaving saving time easily.

The utility model has overcome the described deficiency of background technology, and the gasoline engine that utilizes sprayer is as power, and the time spent still can not be loaded on gasoline engine on the sprayer and use, and reduces production costs greatly and price.Because complete machine structure is simple, volume is little, in light weight, after power set quit work, also can at will on field and road, promote, being fit to very much farmland, booth, orchard, forest farm etc., to locate farming, sowing, fertilising used.
