Description

Rear-turning digging type tiller

The utility model relates to the arable land device that agriculture dry land is used, and is particluarly suitable for using on the tractor of various types.

The arable land is that agricultural is carried out the indispensable step of seeding operation, and current ploughing and two kinds of cultivated land modes of rotary tillage of generally adopting are promptly carried out operation by tractor-drawn ploughing device or rotary cultivator attachment.The colter elevating mechanism that the ploughing device mainly comprises colter, is connected with colter is fixed on the ploughing device on the car body of tractor by connector, utilizes the colter elevating mechanism control arable land degree of depth or lifts colter.This ploughing device, as the double-bladed plough cutter, following two significant disadvantages are arranged: (1) tractor direction of advance is identical with the colter direction of advance, and the tractor-drawn colter must open the unploughed land in the place ahead, resistance is very big, thereby makes the tractive force consumption of tractor too big.Because the increase of tractive force has strengthened the frictional force between tractor driving wheel and soil, causes the serious backing compacting of driving wheel to the soil, especially on the big slightly clayed ground of water content, the soil produced many clods cakings after the backing compacting made and ploughs; (2) owing to colter is only digged to a direction, the loosening the soil of dead furrow that driving wheel will have been ploughed rolled reality, soil after ploughing also need with manpower or animal power rake the smooth edge of a field of dead furrow, smash work such as clod, cause the quite heavy duplication of labour, wasted manpower, very cause also and loss of moisture phenomenon can occur, influence is sowed on time.Another kind of rotary cultivator attachment mainly is made of the connector of rotary colter, colter rotating mechanism, colter elevating mechanism and this device and tractor car body.Though this device has the smooth advantage in small, broken bits in soil, the back of ploughing is arranged, yet its shortcoming also is tangible.The first, because structure is limit and can not be deep ploughed, do not reach many crops and plough the agriculture requirement of broadcasting; The second, the frictional force that produces between rotation colter and soil is too big, makes under the layer of ploughing after ploughing that loosens the soil the phenomenon that hardens to occur, and causes the hard arable land of last Panasonic of the root growth that is unfavorable for plant.Because the critical defect that above-mentioned existing cultivated land device exists, improving the cultivated land device has become the urgent hope of people.

The purpose of this utility model is to design a kind of novel arable land device, reduces the traction power that cultivated land is consumed, and avoids being rolled real shortcoming because of colter again to the direction dead furrow that causes having ploughed of digging.

Rear-turning digging type described in the utility model arable land device mainly comprises colter and colter elevating mechanism, and colter is that the lower end is the tunneling rod 7 of shovel shape 10, and shovel shape 10 parts can be formed in respectively with tunneling rod and be linked to be integral body, also can make with tunneling rod is whole.The colter elevating mechanism comprises crank 6, axle 11, driving member 5, supporting 4, connecting rod 9, bearing 8.Crank 6 one ends are fixedlyed connected with axle 11, and the other end and tunneling rod 7 are hinged, driving member 5(such as gear, sprocket wheel, belt pulley etc.) be installed on the axle 11, by supporting 4 with axle 11 fixed installations (as on the suitable position of tractor).Connecting rod 9 one ends and tunneling rod 7 are hinged, and the other end and bearing 8 are hinged, the bearing 8 fixed installation suitable position of tractor (as be installed in).Supporting 4 can be bearing block or the housing that has the transmission device of bearing block.

In order to improve ploughing capacity, rear-turning digging type described in the utility model arable land device comprises the colter that (contains two) more than two and (contains two) more than two the colter elevating mechanism at least.

In order to increase the arable land width and to improve operating efficiency, when wishing that a part of tunneling rod 7 carries out digging, another part tunneling rod 7 carries away ground, alternately digging mutually, under certain drawbar horsepower, can reach the purpose that enlarges the arable land width, for this reason, two tunneling rods 7 and two colter elevating mechanisms constitute one group, 120～180 ° of angles of staggering between two cranks 6 of every group.

When using rear-turning digging type described in the utility model arable land device, be connected by the transmission case of driving member 5 with pulling equipment (as tractor), drive axle 11 and crank 6 rotations, make the motion that picks up of tunneling rod 7 certain track by crank 6 and connecting rod 9, make the spade position 10 of tunneling rod 7 insert the soil with the approximate vertical direction, similar manually milling with iron picks up, and earth is opened to the direction pick that pulling equipment advances opposite, and the spade 10 of tunneling rod 7 carries away ground then.Along with the rotation that crank does not stop, tunneling rod 7 does not stop picks up and carries away ground, so goes round and begins again.This device described in the utility model is because digging backward, the power thrusts of colter digging all is loosening the soil of having dug out, thereby reduced native resistance significantly, and the cultivated plough power thrusts of existing ploughing device is identical with the pulling equipment direction of advance, must overcome the powerful resistance of hard unploughed land, basic reason that arable land described in the utility model device obviously saves power that Here it is.Facts have proved, use rear-turning digging type cultivated land device described in the utility model to plough, can obviously save traction power, reduce energy resource consumption.
