Abstract

The utility model discloses a small traction type tillage implement. In the small traction type tillage implement, a single beam traction frame is composed by a horizontal main beam, a traction beam and a support beam, the traction beam and the support beam are respectively arranged on the front end and the back part of the main beam and are vertical to the main beam, a traction head is arranged on the front end of the head of the traction beam, the back end of the head of the traction beam is provided with a plow harrow fixing device, the middle part of the main beam is provided with a plow harrow lifting device, the rear tail part of the main beam is provided with a driver seat, and the bottom of the support beam is provided with a piece of slide plate. When the small traction type tillage implement is used to plow and harrow fields, the driver can sit on the seat to operate, the depth of the plow harrow can be regulated from time to time according to the concrete situation of the fields, the labor intensity is reduced, and the quality of the plowed and harrowed fields are improved.

Description

Small-sized towed seat plowing device

The utility model relates to a kind of small farm plow harrow device, especially a kind of plow harrow device that is used as power with small hand tractor.

Current in the vast rural area of China, the plow harrow device that is used as power with the small hand tractor of 4～6 horsepowers, owing to be subjected to factor ground restrictions such as horsepower, when farm work, normally directly a plough or rake are contained on the traction frame of tractor rear, the tractor driver then follows in the walking of the back of tractor, and the plough or the depth that harrows a field are to finish by the handrail of raising with hand or reduce tractor.The shortcoming of this device is: (1) tiller follows in the walking of tractor back, and labour intensity is big; (2) depth in plow harrow field is by directly raising or reduce the handrail of tractor with hand, not only inconvenience but also very effort.

The purpose of this utility model provides a kind of operation that can be seated, and regulates the small-sized towed seat plowing device of the plow harrow depth convenient and labor-savingly.

For achieving the above object, the utility model has designed a single-beam hitch frame, and this hitch frame is positioned at the girder front end draw beam vertical with girder and one and is positioned at the girder rear portion brace summer vertical with girder and forms with one by the girder of a level.At the head front end of draw beam the drawing head that the traction frame of an energy and traction hand tractor afterbody flexibly connects is set, the rear end is provided with a plow harrow fixture, during farm work, traction frame with drawing head and tractor rear flexibly connects with a latch earlier, will plough or harrow to be fixed on this device.At planker of the bottom of brace summer fixed installation, this planker contacts with ground, plays the effect of the heavy-handed amount of support machine.On the back afterbody of girder, tractor driver's seat is set, take when farm work for the tractor driver.

In order to realize regulating the plow harrow depth convenient and strength-savingly, the utility model is fixed on the activity of being designed to of plow harrow fixture the rear end of draw beam head, a plow harrow elevator is set on horizontal girder again, this device and plow harrow fixture are coupled together, by the control operation elevator, reach the position that promotes or reduce the plow harrow fixture, and then reach the purpose of regulating the plow harrow depth.

When farm work, because the depth difference in various fields, soil property soft or hard degree difference causes the degree of depth difference in brace summer and the planker wedging soil.In order to keep the hitch frame girder to be horizontal, guarantee that operation is normal, must in time regulate and support depth of beam.The utility model is by be inserted in the elevating lever that can slide up and down in the bottom of brace summer, planker is fixed on the bottom of this elevating lever, utilize sliding up and down of elevating lever to regulate the support depth of beam, and being connected and fixed of elevating lever and brace summer, be by opening several adjustment holes that match at the head of elevating lever and the bottom of brace summer, with a latch pass on the bar and beam on a certain adjustment hole connect fixing.

The advantage of the small-sized towed seat plowing device of the utility model is: (1) tractor driver is seated and carries out farm work, has greatly alleviated labour intensity, and makes operation not be subjected to the influence of tractor driver's muscle power, thereby also can improve operating efficiency significantly; (2) can in time regulate the depth of plow harrow by the convenient and strength-saving ground of plow harrow elevator, thereby can improve the quality in plow harrow field.

Below in conjunction with accompanying drawing the small-sized towed seat plowing device of the utility model is described in further detail.

This accompanying drawing is the main TV structure schematic diagram of the small-sized towed seat plowing device of the utility model.

As we know from the figure, the hitch frame of the small-sized towed seat plowing device of the utility model is made up of with a hollow draw beam (2) vertical with girder that is positioned at the girder front end and the hollow girder rear portion brace summer vertical with girder (3) that is positioned at a hollow horizontal girder (1).The head front end of draw beam is provided with the drawing head (4) that the traction frame of an energy and traction hand tractor afterbody flexibly connects, the rear end is provided with a plow harrow fixed frame (5), this frame and draw beam are movable fixing, can make axial rotation around fixed axis, and plough or rake (9) just are fixed on this fixed frame.On the girder above this fixed frame, a plow harrow elevator is set, this device is made up of one 7 a font depression bar (10) and a tile height adjustable plate (12), wherein the depression bar activity is fixed on the seat board (11) that is positioned on the girder, the front end of depression bar and the front end of DOCK LEVELER are movable fixing, and evenly have several adjustment holes on the adjustable plate, after connecting rod on the fixed frame (15) and the flexible connection of a certain adjustment hole, just can be by pressing the rear end of pressure-raising bar, the drive fixed frame rotates, thereby reaches the height that promotes or reduce plough or rake.Also have several fixing holes (14) on seat board, these holes are sequentially arranged in to be on the circular arc of radius to pivot distance, also have a hole that matches on the correspondence position of depression bar, by latch depression bar are fixed on the seat board.In the bottom of brace summer, be inserted in an elevating lever (6), this bar can slide up and down in brace summer, to reach the purpose of regulating the brace summer height.And being connected and fixed of elevating lever and brace summer is by opening several lifting position adjustment holes (13) that match at the head of elevating lever and the bottom of brace summer, with a latch pass on the bar and beam on a certain adjustment hole connect fixing.In the bottom of elevating lever, fixedly connected one is dragged piece (7), and this planker plays the effect of supporting tractor driver and whole hitch frame.Tractor driver's seat (8) is set, the usefulness that supplies the tractor driver to take on the back afterbody of girder.
