Description

Pull out the stalk device

One, technical field

The utility model belongs to a kind of stem stalk mechanism of pulling out in the farm machinery.

Two, background technology

After the crops results, stem root root stubble is stayed the field, and under the situation that adopts shop film plantation, the existing stalk machine of beating because of fearing to hurt cutter, is laid the liftoff certain altitude of stalk come, and stayed stubble, punctures mulch film when influencing later stage membrane removal and 1 year planting after plastic covered.If can extract with root the stem stalk, solve the problem that punctures mulch film when influencing later stage membrane removal and 1 year planting after plastic covered.Lack the place of making meal fuel interiorly, the stem stalk is extracted to make full use of act as a fuel, then can pull out stalk, membrane removal, chopping and returning in the place that does not lack fuel and once finish.Have a kind of craft to pull out the stalk instrument, be made up of handle, jaw and support arm, jaw is bitten the stem stalk during work, and support arm lands and firmly will lift on the handle, the stem stalk can be extracted, and this instrument efficient is lower.Also have a kind of stalk device that pulls out to be made up of two groups of belts, the belt inclination is installed, and working face compresses mutually, the stem stalk can be clamped and is pulled up and, and its shortcoming is, if tightly can not make the slippage of stem scale owing to pressing from both sides in the belt running.

Three, summary of the invention

In order to overcome above-mentioned deficiency, designed a kind of new stalk device that pulls out, can reliably crop stem be pulled up.This stalk device that pulls out is formed by pressing from both sides the stalk fluted disc and unclasping mechanism's two parts.Folder stalk fluted disc comprises oscillating tooth dish, fixed tooth disk and three dishes of supporting disk, has spacer sleeve to connect the location therebetween, and is fixed on the arbor.The oscillating tooth dish is that hinged 8 sector dental laminas are formed on the dish core of fixing, and the teeth on the teeth plate are corresponding with the teeth on the fixed tooth disk, and the addendum line of teeth is oblique line, and the tooth top of two teeth forms the little horn mouth of outer imperial palace.Motion bar hinged on the supported dish of sector dental lamina on the oscillating tooth dish supports the location from a side.Uncoupling gear has two little gardens dishes and spacer sleeve to link together to be fixed on the axle, and there are 8 holes the corresponding position of going up in garden week of two little garden dish same diameter, and push rod passes from the hole, withstands on the another side of the sector dental lamina of movable disk.Holddown spring is housed on the push rod, and roller is equipped with on the top.The position of roller motion is provided with track.This stalk device that pulls out pulls out the stalk dependable performance, can regulate according to the distance of crop row distance and pull out stalk Unit Installation position, convenient being suitable for.

Five, embodiment

Below in conjunction with accompanying drawing embodiment is described further.Pulling out the stalk device and be installed on the frame, is the crop stem that field after gathering in the crops is stayed, and (cotton stalk, beans stalk etc.) pull out the facility of operation.Axle (15) is installed on frame (1) as shown in Figure 1, pulls out the stalk device and be fixed on the axle (15), and can move adjustment vertically.Pulling out the stalk device can be as big as and be divided into folder stalk fluted disc and unclasp mechanism's two parts.Folder stalk fluted disc comprises the dish of oscillating tooth dish (9), fixed tooth disk (11) and (13) three equal diameters of supporting disk.Two spacer sleeves are arranged, to fix their relative position between three dishes.They are linked together by bolt, are fixed on the axle (15) by screw again.In the same garden of its card 8 movable pole sockets (12) were arranged on week as Fig. 7 Fig. 8 institute Chu supporting disk (13), hinged 8 motion bars (10) on it, motion bar can radially turn round, and the back-moving spring on the motion bar (16) returns to and axle (15) parallel position it.Uniform 8 teeth (18) on the card of the fixed tooth disk of centre shown in Figure 2 (11) also have 8 radially slotted holes (17) and the alternate configurations of teeth (18) on the dish.Motion bar (10) is passed by slotted hole (17), in the hole activity freely, the roller of its top dress withstands on the side of oscillating tooth dish (9) sector dental lamina (20).The structure of oscillating tooth dish such as Fig. 4, shown in Figure 5, dish core (21) joins with spacer sleeve, is fixed on the axle (15).Hinged 8 the sector dental laminas of its periphery (20), the teeth on the teeth plate (19) are along the straight line setting radially of sector dental lamina, and vertical with the plate face.These teeth (19) are relative with the teeth (18) on the fixed tooth disk, and both crest lines tilt, and form the little horn opening of outer imperial palace, so that the stem stalk enters between the teeth.Opposite side at oscillating tooth dish (9) is to unclasp mechanism, and it has two identical little garden dishes (5) and (8) and middle spacer sleeve (22), and the three links into an integrated entity by being bolted on the axle (15).Figure 6 shows that and unclasp mechanism's medium and small garden dish, spacer sleeve and the installation situation of holding screw on axle (15).Last corresponding 8 holes that are evenly equipped with of garden week of two little garden dish same diameter, push rod (7) passes from the hole, and the energy activity freely, withstands on sector dental lamina (20) another side of oscillating tooth dish (9).Push rod is equipped with holddown spring (6) in dish centre position, two little gardens, and two rollers (3) are installed on the top of push rod, are provided with the two-orbit (4) that is fixed on the frame at the roller movement position.Pull out the horn mouth aligning stem stalk feeding mouth (14) that the installation of stalk device on frame (1) should make teeth (18) and (19).At the leisure state, motion bar (10) is positioned at and axle (15) parallel position by the slotted hole of fixed tooth disk (17), and the sector dental lamina (20) of oscillating tooth dish is positioned at and axle (15) vertical position by motion bar (10) and push rod (7).During work, crop stem enters the teeth horn mouth from feeding mouth (14), promote motion bar (10) and inwardly rotate along fixed tooth disk slotted hole (17), the sector dental lamina (20) of oscillating tooth dish is turned to fixed tooth disk (11) by push rod (7) institute roof pressure, teeth (19) and teeth (18) is drawn close clamp the stem stalk.When unit advances, wholely when power input wheel (2) drives axle (15) and rotates pull out that the stalk device is coaxial to rotate simultaneously.Rod-pulling device and land wheel direction of rotation are raised from soil clamped stem stalk and extract.Roller (3) on the push rod (7) moves to left push rod rising gradually along track (4) in the revolution backward, removes the roof pressure to oscillating tooth dish sector dental lamina (20), and the teeth plate is subjected to back-moving spring (16) effect of motion bar (10), is pushed up and gets back to stand up position.Teeth (19) are separated with (18), and the stem stalk that is pulled out pitches.And two rollers (3) break away from two-orbit (4), and push rod (7) sets back.8 groups of teeth are gone round and begun again and are taken turns to operate, and make to pull out the stalk operation and continuously carry out.The above-mentioned stalk device that pulls out can only be aimed at a plant and advances and pull out the stalk operation, according to the size of crop row distance and unit working width, can install in the frame relevant position and pull out the stalk device more than 2.
