Abstract

The utility model discloses a tilling ditchdigger which comprises a gasoline engine, a worm wheel and worm reducer, a main frame and a rotary tool, wherein the main shaft of the engine is connected with the worm shaft of the reducer through a coupler; the rotary tool is arranged at two ends of the shaft of the worm wheel, and the blades are evenly distributed on the circumference of a tool body and are slantways arranged with a left mode and a right mode. When the tilling ditchdigger drives forward, the blades can quickly remove the weed; that the tilling ditchdigger drives backward can form grooves among crops, which is convenient for fertilization or growth of a plurality of ridging crops. The utility model is fit for cultivation, weeding and ditching during the growth of the crops.

Description

Tilling ditchdigger

The utility model belongs to agricultural tillage machinery, is specifically related to a kind of Tilling ditchdigger.

In plant growing process, need in time intertill, hoe up weeds, ditch, topdress.Also do not have special-purpose small farm machine at present in this stage, most of rural areas are still continued to use livestock and are drawn plough to hoe the fields, ditch, and manually hoe up weeds, and labour intensity is big, inefficiency.

The purpose of this utility model provides a kind of simple in structure, the small-sized Tilling ditchdigger that is suitable for cultivation uproot flexible and convenient to use.

Technical solution of the present utility model is: Tilling ditchdigger is made up of petrol engine, worm type of reduction gearing, frame, rotating knife.Petrolic main shaft is connected with reducer worm shaft by shaft coupling; Shaft coupling is arranged in the frame support sleeve pipe, supporting sleeve one end is connected with the seat board of stationary engine, and the other end is connected with the housing of decelerator, and frame support sleeve pipe upper end is fixed with the operation handle support base, the lower end is fixed with the support wheel support, and support wheel is contained in the support both sides; At the worm-wheel shaft two ends rotating knife is housed, rotating knife is made up of cutter hub and blade, and blade is distributed on the cutter hub circumference, and adjacent knife blades is the first from left right bank setting; Baffle plate is arranged between support wheel and the rotating knife.

Further describe the utility model below in conjunction with accompanying drawing:

Fig. 1 is the Tilling ditchdigger structural representation;

Fig. 2 is the end view of Fig. 1;

Fig. 3 is engine spindle and reducer worm shaft connection diagram;

Fig. 4 is rotating knife and worm-wheel shaft connection diagram.

Wherein, 1, operator is 2, operator is fixed mount 3, operation handle support base 4, regulate slotted hole 5, petrol engine 6, engine supporting plate 7, support wheel support 8, fuel tank 9, frame support sleeve pipe 10, baffle plate 11, worm type of reduction gearing 12, blade 13, cutter hub 14, support wheel 15, rotating knife 16, bolt 17, engine spindle 18, key 19, connecting axle 20, worm shaft 21, key 22, the sleeved cutter hub 23 of one side, bolt 24, the sleeved cutter hub 25 in both sides, key 26, worm-wheel shaft 27, screw 28, reducer shell

As shown in Figure 1 and Figure 2, engine 5 of the present utility model adopts petrol engine, and engine is provided with fuel tank 8; Decelerator 11 adopts worm type of reduction gearing, and engine and decelerator are separately positioned on frame support sleeve pipe 9 two ends.Seat board 6 welding of frame support sleeve pipe 9 one ends and stationary engine, the other end is fixedlyed connected with reducer shell 8 by bolt.Baffle plate 10 is arranged between support wheel 14 and the rotating knife 15, and fixedlys connected with reducer shell 28.Engine spindle 17 and reducer worm shaft 20 are connected by shaft coupling, and shaft coupling of the present utility model is the connecting axle 19 that two ends have keyway, and connecting axle 19 is connected by

key

18,21 with reducer worm shaft 20 with engine spindle 17, as shown in Figure 3.

Frame support sleeve pipe 9 upper ends are welded with operation handle support base 3, and the lower end is welded with support wheel support 7, and support wheel 14 is contained in support 7 two ends.Operator is connected with fixed mount 2 to 1 lower end, and fixed mount is connected with bearing 3 on being fixed on supporting sleeve by bolt 16, and bearing is provided with regulates slotted hole 4.By regulating the position of bolt, can make operator raising or reducing, to adapt to action need.

The quantity of rotating knife can be provided with as required, for the little spacing crop of cereal, can adopt one group of rotating knife, for the big crop of spacing, can adopt two groups or three groups of rotating knifes.Rotating knife is arranged on the two ends of worm-wheel shaft 26, the blade 12 of rotating knife and cutter hub 13 riveted joints, and the blade extended line of blade is by the axial line of cutter hub.One or both sides at the rotating knife cutter hub are welded with sleeve, the sleeved rotation cutter hub 24 in both sides is contained in the axle head of worm-wheel shaft 26, and be connected by key 25 with worm-wheel shaft, also be processed with screw in the worm-wheel shaft axle center, by screw 27 cutter hub and worm-wheel shaft are fixed: the sleeved rotation cutter hub 22 of a side, its sleeve is inserted in the cutter hub sleeve of worm gear axle head, and two sleeves are examined 23 fixedly connected by spiral shell, as shown in Figure 4.

The utility model adopts the power of the petrol engine of 1.8KW as Tilling ditchdigger, by the motor driven worm type of reduction gearing, drives the rotating knife rotation on the worm-wheel shaft, hoes up weeds trench digging.When Tilling ditchdigger was advanced forward, the blade of rotating knife can be uprooted weeds fast; When needing trench digging, Tilling ditchdigger is dragged backward, rotating knife can screw out soil to both sides, make to form groove between crop, is convenient to fertilising, or plants some ridging crops.

The utility model compact conformation, reasonable in design, flexible and convenient operation, low cost of manufacture, be particularly suitable in the process of crop growth intertillage, hoe up weeds, ditch, be a kind of small practical trench digging agricultural machinery of hoing the fields.
