Description

The side-lining Machine for cutting shrub stubble

The utility model relates to a kind of with the machine of tractor side-lining shrub stubble flattening, especially be installed in the tractor with small four wheels trailing flank can carry out the shape cutting shrub automatically to ground stump machine.

Shrub is the drought resisting seeds that afforestation area is big, distributed areas are wide, especially caragana microphylla, red building seeds, it not only can windproofing fixed sand, and belongs to the high-quality feed of rich in proteins, its growth rhythm is that every interval must carry out once cutting off from root in 5～7 years is stump, otherwise can nature withered.At present results caragana microphylla and the most frequently used method of red building are that artificial the use sticked up a head felling stump, artificial tongs stump and with backpack brush saw stump, these stump mode production efficiencys of gathering are extremely low, and hand labor intensity is big, the cost height of gathering.Therefore, shrub---especially the stump of caragana microphylla, red building is gathered becomes the outstanding problem that the western arid area of China turns to the economic benefit urgent need to solve by ecological benefits.

Be to improve stump efficient, the utility model side-lining Machine for cutting shrub stubble provides the results shrub of a kind of side-lining at the tractor with small four wheels trailing flank---the stump machine of caragana microphylla, red building seeds especially.When operating personnel handle the tractor that flat stubble machine has been installed shrub are carried out the stump operation, its shape cutting system can be automatically according to the height on ground, root to shrub cuts, and pallet apparatus can make the cutter tooth of cutting blade and ground keep certain stump height.The round cutter sheet of the multiple tooth shape that studs with carbide alloy of high speed rotating, when cutting shrub on the soil of earth on sandstone, it is less to wear and tear, and cutting blade folds setting, has prevented the cutting dead angle.The axis that cutting blade is arranged has a discharge angle with the direction of advance of tractor, and this discharge angle can make the branch that the is cut protective cover outside the gear-box, fitly slides to ceding of Taiwan side and back automatically.

The technical scheme that its technical problem that solves the utility model side-lining Machine for cutting shrub stubble adopts is: with one group of bolt system frame is fixed on the tractor machine back axle earlier, with one group of bolt the balancing pole support is fixed on the system frame again, four connecting rod fixed supports and balancing pole support are fixed together, on, an end of four connecting rod rests is connected with pin with four connecting rod fixed mounts respectively down, the other end is connected with ceding of Taiwan fixed mount backboard with pin, form parallel four-bar linkage, like this, the ceding of Taiwan bottom face that connects can be guaranteed to be attached thereto in taiwan cut off and landing rises and falls, ground level can be parallel to all the time.Ceding of Taiwan fixed mount backboard, ceding of Taiwan fixed mount and the welding of ceding of Taiwan frame are fixing.On the ceding of Taiwan frame gear-box is installed, is connected by universal drive shaft cover connecting pin with universal axle sleeve between each gear-box.On the output shaft of gear-box vertical direction, the cutting blade that studs with carbide alloy is installed, cutting blade plane and horizontal plane have an inclination angle.On the lower plane of ceding of Taiwan frame bottom, pallet is installed, and pallet wraps up the major part of cutting blade, has only the cutter tooth part to contact with ground when making cutting blade work, other position does not contact with ground, thereby has greatly reduced the working resistance of cutting blade.During ceding of Taiwan work, under the effect of balance sysmte, pallet is attached on the ground all the time, and cutting blade also has a bit of distance apart from ground.The power input shaft of several gear-boxes is connected by the high speed shaft of universal drive shaft with the raising speed gear-box.The slow-speed shaft of raising speed gear-box is gone up transfer gear box by another root universal drive shaft with one of installation gear box of tractor and is connected.Form by a pair of bevel gear, jaw clutch and gear shaft in the transfer gear box, stir the jaw clutch driving lever, bevel gear is separated or combination.The jaw clutch driving lever is in a side of operating seat.The balancing pole support of installing on the frame is fixed in the above balancing pole with the balance lever pin.Balancing pole is made up of for two sections single pole section and two bar section, and two bar Duan Yiduan of balancing pole are equipped with balancing weight, and the other end and single pole section are fixed by connecting pin.The link plate that the other end of single pole section is put on the shelf by articulated slab and last four connecting rods is hinged.The weight of all parts of installing on four linkages and the ceding of Taiwan frame is formed the imitative type system of gravitational equilibrium greater than the weight of balancing pole and balancing weight in the fulcrum both sides, contact the variation that rises and falls with ground with pallet, and the ceding of Taiwan is carried out the height lifting with ground automatically and changed.Because of holding tray surface contact parallel to the ground all the time, and cutting blade plane and holding tray surface are except that having an inclination angle, cutter tooth also has a segment distance with holding tray surface, and the cutter tooth of cutting blade is not contacted with ground at work, thereby has reduced the working resistance and the wearing and tearing of blade.The cutting blade of installing on adjacent two output shaft of gear-box folds setting, and is overlapping on the diametric(al) of arranging, and when adjacent two cutting blades are rotated, promptly do not interfere, and can not produce the cutting blind area again.For eliminating foozle and the alignment error between the gearbox, make the power smooth transfer, connect with the axle sleeve universal joint between the gearbox.For making the side-lining Machine for cutting shrub stubble from the residence to the operation area or from the operation area to the residence, can walk easily, the ceding of Taiwan can rotate to the tractor rear side around ceding of Taiwan rotational pin together with ceding of Taiwan fixed mount backboard, two bar sections of balancing pole also can connect bearing pin around it and rotate, like this, machine volume diminishes, and makes tractor more convenient when non-operation is walked.

The beneficial effect of the utility model side-lining Machine for cutting shrub stubble is, during the work of this machine, because the ceding of Taiwan is installed in the trailing flank of tractor, so, when the stump operation, the driver can allow tractor dodge out those shrub roots artificially and deposit sandy soil heap for many years, the shrub that only allows the ceding of Taiwan aim at the last growth of those sandy soil heaps carries out the stump operation, tractor in the ranks travels in the shrub of relatively flat, root stubble after not going to roll shrub and be cut, thereby saved the power of tractor, and prolonged the service life of tractor tire.Because the weight of balancing pole and balancing weight is slightly less than the weight of all fixing in ceding of Taiwan parts,,, thereby realized the automatic profiling cutting of the ceding of Taiwan to ground along the curved surface fluctuations of sandy soil heap so pallet can keep in touch with ground all the time.Because ceding of Taiwan integral thickness size is less, the longitudinal axis inclination certain angle of the connection axis of blade and tractor is so the material that is cut fitly slides to the tractor rear side automatically along the side and the top of ceding of Taiwan guard shield again.There is a top rake on several round cutter sheet and ground that stud with carbide bit, and this angle can make cutting blade when the cutting shrub, makes the otch of root stubble smooth, and the hair stubble is few, does not have the burnt phenomenon of sticking with paste, and is more conducive to the root stubble and germinates in this year.
