Description

A kind of small cultivator

The utility model relates to a kind of agricultural machinery, is the small cultivator of a kind of suitable paddy field, nonirrigated farmland operation specifically.

At present the tiller that generally uses of China rural area adopts circular single-wheel or two-wheel to drive walking mostly, and the engine of single-wheel type places on the gearbox, outstanding high, smoothness is poor, relies on monolateral stock to land balance support, is not suitable for the nonirrigated farmland operation; Though the tiller of twin type is fit to the nonirrigated farmland operation, efficient is low when paddy-field-working; The common defects of the tiller of these two kinds of types is: heaviness, can not be in the mountain region and the walking of narrow ridge, and therefore be difficult in the vast rural area and popularize, more can not replace farm cattle fully.

The purpose of this utility model is, overcomes the above-mentioned defective of existing tiller, provides a kind of volume little in light weight, is fit to the small cultivator of multiple field soil, landform operation.

The technical solution of the utility model is such: design comprises the small cultivator of speed changing power mechanism, travel driving unit, plough, rake jockey, elevation and subsidence regulating device and handrail, the frame of standing; its feature is: 1. speed changing power mechanism is by frame; gearbox and engine are formed; gearbox is located at the place ahead of engine and substantially point-blank; input belt pulley at gearbox adopts embedded; be provided with forward and back retaining in the gearbox, can realize gear shift operation under the stopped status not by the clutch lock.2. travel driving unit adopts double-chain crawler belt, the main drive wheel by being directly installed on the output shaft of gear-box two ends and be directly installed on and drive walking from driving wheel on the frame of gearbox back; On the chain type crawler belt,, be connected with by being located at the outer flanging (53) of chain link stator that the angle bar formula is grabbed mud plate (54) or the T font is grabbed the mud plate every 1～5 chain link.3. the plow harrow jockey is located at the front end of frame and gearbox, and the connecting rod that is welded with, this extension bar are provided with a plurality of connecting rings and farm implements such as roll with single plow or rotary plow or strings of cash consumption, Pu as required and link to each other.The rotary plow of adapted (as shown in Figure 3) with it wherein, it is by fixing ear card (35), and chain bag box (36) sprocket (37) revolves plough driving shaft (38), chain (39), arc supports (40), cutting (41), mud retaining cover (42), support (43), the hole parts such as (44) of shipping and reselling on another market are formed, and this plough turns over mud and broken mud dual-use function, also can with the supporting use of single plow.Said strings of cash rake by the hole of shipping and reselling on another market (31), is harrowed support (32) as shown in Figure 2, rake journal stirrup (33), and rake teeth (34) is formed, and links to each other with the retainer ring (5) of plow harrow jockey with journal stirrup by shipping and reselling on another market.It is by sleeve (45) that said Pu is rolled, depression bar (46), and bracing ring compositions such as (47) can be installed in the walking output shaft outermost end in the main drive wheel dish outside of chain type crawler belt when needing; In order to strengthen the effect that Pu is rolled, can be in the frame bottom at gearbox rear portion, by screw (48), axle (49), gripper shoe (50), depression bar (51), the auxiliary Pu that bracing ring (52) is formed is rolled.4. elevation and subsidence regulating device is provided with highly and regulates and angular adjustment, and highly regulating is that the journal stirrup that will plough tool by shipping and reselling on another market is connected on the connecting ring of suitable height and realizes; The angular adjustment of plough is the company's stalk of shipping and reselling on another market the hole and being attached thereto by plough tool top, links to each other with the action bars that is provided with latch and draw-in groove and realizes ploughing the adjustment of tool angle.

The utility model has the advantages that: 1. the utility model is simple in structure, volume is little, in light weight, be convenient to the carrying or directly on the way the walking, both having made is that narrow trail and hillside can both travel smoothly; 2. because of having used the running gear of two crawler belts, so its pressure is little, the power of creeping is big, and skid resistance is strong, is fit to nonirrigated farmland, paddy-field-working; 3. because the plough tool is arranged on the place ahead of this machine, rather than rear in the past, add easy to operately, angle, field, rand can both be ploughed, reduce manually to turn over and dig.4. the front end of this machine is provided with the farm implements jockey, can articulate single plow or rotary plow as required, and strings of cash rake, Pu are rolled, harvester etc., realize a tractor serves several purposes.

Introduce the embodiment of a band turnplow below in conjunction with accompanying drawing:

Fig. 1 is an overall structure schematic diagram of the present utility model.

Fig. 2 is the strings of cash rake structure schematic diagram of adapted.

Fig. 3 is the rotary plow structural representation of adapted.

Fig. 4 is that the Pu of adapted is rolled structural representation.
