Description

The automatic reversing two-way plow of two ploughshares

The utility model relates to a kind of machinery of plowed soils, particularly a kind of two ploughshare reversible plows that automatic turning device is arranged.

The present supporting pivot plow of China and the tractor with small four wheels good approved product of neither one also, that sells on the present market mostly is manual upset and mostly is single ploughshare, and production efficiency is low in utilization, complicated operation, driver's workload is big.

The purpose of this utility model provides a kind of two ploughshare reversible plows that can overturn automatically.

The purpose of this utility model is achieved in that the plough axle assembly that it comprises by girder pipe, traction crossbeam, goes up plow beam assembly that suspension plate connects to form and be made up of main shaft and plough crossbeam, plow standard, ploughshare, it is characterized in that: the front end at main shaft is movably installed with communtation arm, in the outer stomidium of communtation arm commutation is housed and draws pin, commutation draws pin to articulate mutually with the lower link that is fixed in the tractor rear portion by turnover spring; One vertical hole is arranged in the communtation arm, pad is housed in the hole, the pad upper and lower end draws pin, clamping block to contact with commutation respectively; Reversing plate is fixedly mounted on the main shaft, and reversing plate is a covering of the fan shape, and an arcuate socket is arranged on it, and the two in hole has pin to decide groove, and respectively there is a projection outer end, reversing plate both sides; Clamping block is through in the arcuate socket of reversing plate, and the rear end is enclosed within on the hinge, and locking spring one end hangs on the clamping block, and the other end hangs on the pin that is fixed on the suspension plate; Return arm-tie epimere has a cylindrical void, and the higher authorities of cylindrical void are positioned on the reversing plate by screw, and spacing pin is fixed on the traction crossbeam and is through in the cylindrical void of return arm-tie, lower end that hangs over the return arm-tie of return spring, and the other end hangs on the communtation arm.

The purpose of this utility model can also following manner realize: ploughshare has two in each direction group.

The utlity model has following advantage: by the automatic reversing apparatus that the utility model is provided with, made full use of the power of tractor, need not special messenger's operation, when turning, can realize automatically the upset ploughed greatly reducing labour intensity, improved production efficiency.It is smooth to plough the plot, back, and dead furrow is few, is easy to smoothly, and the improvement of being ploughed in the slope has very big benefit especially.Adopt the two ploughshare structures of twin beams also to solve the shortcoming that single ploughshare working width is narrow, plough body is big simultaneously.

Elaborate below in conjunction with accompanying drawing:

Can be divided into three parts on the utility model structure, plow beam assembly, plough axle assembly and automatic reversing apparatus.The plow beam assembly is welded to form by girder pipe 13, traction crossbeam 14 and last suspension plate 15 threes, and girder pipe 13 plays the stent support effect as the sleeve pipe of upset main shaft.Traction crossbeam 14 is a rectangular tube, two ends are welded with towing pin, last suspension plate 15 is made up of the gusset of two blocks of parallel triangle steel plates and back welding, and suppending hole is arranged at the top, and the plow beam assembly is realized being connected with tractor-drawn with the suppending hole on the last suspension plate by the towing pin at traction crossbeam two ends.

The plough axle assembly is made up of main shaft 16, plough crossbeam 17, plow standard 18, ploughshare 19, and main shaft 16 is through in the girder pipe 13, and plough crossbeam 17 is fixed on the main shaft 16, fixedlys connected with plough crossbeam 17 in plow standard 18 upper ends, and ploughshare 19 is installed in the lower end.Each direction group is installed two ploughs crossbeam, plow standard and ploughshares respectively, is two-way double-bladed plough.

Automatic reversing apparatus: be movably installed with communtation arm 5 at main shaft 16 front ends, commutation is housed in the communtation arm 5 outer end cylindrical voids draws pin 3, commutation is drawn and is articulated turnover spring 2 on the pin 3, and the other end of turnover spring 2 is connected on the lower link 1, and lower link 1 is fixedly mounted on tractor rear.One vertical hole is arranged in the communtation arm 5, pad 4 is housed in the hole, pad 4 upper and lower ends draw pin 3 with commutation respectively, and the front end of clamping block 10 contacts.Reversing plate 9 is fixed on the main shaft 16 by pin, and reversing plate 9 is a covering of the fan shape, on an arcuate socket is arranged, there is lock slots at the two in hole; There is the spacing projection of pair communtation arm outer end, reversing plate 9 both sides.Clamping block 10 is through in the arcuate socket of reversing plate 9, the rear end is enclosed within on the hinge 11, locking spring 12 upper ends hang on the pin that is fixed on the suspension plate 15, the lower end hangs clamping block 10, return arm-tie 6 epimeres have a cylindrical void, and the higher authorities of cylindrical void are positioned on the reversing plate 9 (return arm-tie 6 can around screw turns) by screw, and spacing pin 8 is fixed on the traction crossbeam 14 and is through in the cylindrical void of return arm-

tie

6,7 one lower ends that hang over return arm-tie 6 of return spring, the other end hangs on the communtation arm 5.

The course of work: plough when the work of direction of advance, each position component state as shown in Figure 2, clamping block 10 draws in the lock slots of reversing plate 9 holes one end, realizes the location of plough main shaft and plow beam assembly by clamping block.When ploughing tractor turning to the end when return, because suspension plate 15 has 10 ° inclination angle on the communtation arm 5 of design and the plow beam assembly, so turnover spring 2 drives commutation and draws pin 3 under lower link 1 pulling, commutation draws pin 3 to press down to make pad to be about to the lock slots that clamping block 10 extrudes on the reversing plates 9 for 4 times, and reversing plate 9 goes out of lock with the plow beam assembly.Turnover spring 2 pulls on moving communtation arm 5 and rotates, the projection that 5 groups of communtation arms are lived reversing plate 9 limit ends drives the commentaries on classics downwards together of reversing plate 9, main shaft 16, when going to the lock slots position of reversing plate another side, clamping block 10 enters in the groove under 12 effects of locking spring, at this moment tractor turns to, and turnover spring 2 has loosened.Plough main shaft 16 is realized locating once more with the plow beam assembly by reversing plate 9, clamping block 10.Communtation arm 5 is back to reversing plate 9 under the effect of return arm-tie 6, return spring 7 another side raised position is waited for the pulling once more when next time turning.
