Description

The special-purpose plough of hand tractor

The utility model belongs to tractor-mounted reversible plow technical field.

At present and the reversible plow of hand tractor adapted, as the patent No. is that " walking tractor matching suspension reversible plow " its maximum defective of ZL90223863.9 is that plough shovel and plough mouldboard are connected to one, though can two-way farming, but its plough mouldboard scraping, band soil are seriously, be actually the soil-shifting operation, the ridging operation effectiveness is poor, and working resistance is big.And complex structure, it is big to adjust difficulty.Though it is ploughed adjusting device partially and changes fluted disc type into now, the adjusting range underaction causes the excessive or too small of tilling width often, causes the waste of land wastage or manpower.

It is flexible that the purpose of this utility model provides a kind of adjusting, the reversible plow of the effective walking tractor matching of digging.

For achieving the above object, the utility model is by the following technical solutions: it has two plow beams, the front end of two plow beams is hinged with and the back-connected hanger bracket of tractor by bearing pin, and the plow beam rear end also is hinged with the plow frame Connection Block by bearing pin, and plow frame Connection Block rear end is hinged with the hook type plow frame.On hanger bracket and plow beam, be equipped with and plough adjusting device partially, on plow frame Connection Block and plow frame, depth adjustment is installed.Its design feature is to be fixed with a sleeve pipe in the lower end of plow frame, plough shovel installation shaft is housed in the sleeve pipe, this front end is installed with the plough shovel, its rear end is equipped with the regulating handle that can pull its rotation, the plow frame back is fixed with the regulating handle locating rack, plough mouldboard is movably arranged on by hinge on the bearing that is fixed in the plow frame front, and the plough mouldboard lower end contacts with the activity of plough shovel rear upper surface.Below sleeve pipe, be fixed with and be used to install fixed head at the bottom of the plough plough at the end.

The adjusting device of ploughing partially of the present utility model is by the fan-shaped fluted disc that is welded on the hanger bracket, is fixed on the adjusting rod bearing on the trussed beam and the adjusting rod that is hinged on the bearing constitutes.The central angle of fan-shaped fluted disc is 90 °-120 °, and its arc edge is evenly equipped with 10-16 teeth.Certainly, the teeth of fan-shaped fluted disc also can be less than 10, this moment can be in the adjusting rod bearing hinged side by side two adjusting rods.

Force-bearing situation when ploughing partially for improving, the rear end spacing of two plow beams of the present utility model is greater than its front end spacing, and promptly the distance between its front end two bearing pins is less than the distance between two bearing pins of rear end.

The utlity model has following advantage: the one, the plough shovel cooperates with plough mouldboard is movable, and it is effective to dig during farming, does not scrape soil zone soil, and resistance is little, ridging quality height; The 2nd, adjust flexiblely, it is little to plough amplitude modulation partially, can not cause land wastage during ridging; The 3rd, tractor is stressed rationally, can sideslip, and labour intensity is little.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is a front view of the present utility model;

Fig. 2 is the vertical view of Fig. 1.

In the embodiment that accompanying drawing provides, the utlity model has two phases plow beam 2 across a certain distance, plow beam 2 front ends respectively by a bearing pin be hinged on can with the back-connected hanger bracket 1 of tractor on, plow beam 2 rear ends are hinged with a plow frame Connection Block 6 by bearing pin equally, and plow frame Connection Block 6 rear ends are hinged with the plow frame 10 of hook type.Be welded with a sleeve pipe 18 longitudinally in the lower end of plow frame 10, be fitted with plough shovel installation shaft 17 in the sleeve pipe 18, this front end is welded with a leg-of-mutton shovel fixed head 23, and the plough shovel 24 that is isosceles triangle is installed on the shovel fixed head 23 by bolt.Be fixed with two bearings 11,20 in the front, bottom of plow frame 10, the back side of plough mouldboard 22 also is fixed with two bearings 15, and plough mouldboard 22 is movably arranged on the plow frame 10 by hinge 21 and above-mentioned bearing.In the bottom of plow frame 10 pulling plug 16 is housed also, the front portion of pulling plug 16 is contained on the hinge 21 of plough mouldboard 22 back, and the spring that is sleeved on the pulling plug is arranged in the body of plow frame 10." people " font of opposition about plough mouldboard 22 shaped upper parts are, its lower surface contacts with the 24 rear upper surface activities of plough shovel, is adjacent under above-mentioned pulling plug 16 effects.Rear end in plough shovel installation shaft 17 is hinged with regulating handle 13, and plow frame 10 back are fixed with a regulating handle locating rack 12, and regulating handle 13 shovels between installation shaft 17 rear ends with plough extension spring 14 is housed, and locating rack 12 rear ends are one to have the location-plate of several limited bayonets.When a side is pulled regulating handle 13, it makes plough shovel 24 to the oblique angle of this inclination by plough shovel installation shaft 17, plough shovel 24 promotion plough mouldboards 22 lower ends make plough mouldboard also turn over certain angle and its adaptation simultaneously, handle 13 upper ends are put in people's regulating handle locating rack 12 corresponding bayonet sockets locate then.On plow frame 10 tops and plow frame Connection Block 6, depth adjustment is housed, it comprises and is welded on the adjustment seat 9 that is fixed with a nut on the plow frame 10 its, adjust in the nut on the seat 9 adjusting screw(rod) 8 is housed, the front end of adjusting screw(rod) 8 passes the support plate 7 that is fixed on the plow frame Connection Block 6, and by former and later two nut location.The adjusting device of ploughing partially of the present utility model is by being welded on fan-shaped fluted disc 3 on the hanger bracket 1, being fixed therein an adjusting rod bearing 4 and the adjusting rod 5 that is contained on the bearing 4 of hinge on the plow beam 2 and constituting.The central angle of fan-shaped fluted disc 3 is preferably 90 °-120 °, is evenly equipped with 10-16 on its circumference and regulates teeth 25.The teeth 25 of fan-shaped fluted disc 3 also can be less than 10, for example have only 5 teeth, and can install two adjusting rods 5 this moment side by side on adjusting rod bearing 4, and when locating between two teeth for one, another root is positioned at below the teeth, with the adjusting range that reduces to plough partially.The length unanimity of two plow beams 2, but its rear end spacing is greater than the front end spacing when installing, promptly the distance between front end two bearing pins is slightly less than the distance between two bearing pins of rear end, thereby can improve the force-bearing situation of tractor when cultivated partially, avoids sideslip.Below the sleeve pipe 18 of plow frame 10 lower ends, also be welded with plough end fixed head 19, be equipped with at the bottom of the removable plough below it.
