    Described ball (70) is smooth steel ball;

    Described torsion spring (73) is Mi Quan, and cross section is circular, is convenient to process the end (73b) of its anfractuose L shape end (73a) and U-shaped, the difficult mandrel that weares and teares of the seamed edge because of square torsion when being also convenient to work, described its end of torsion spring (73) (73a) is L-shaped, is stuck in described lock core (72) top therefore be beneficial to, and the other end (73b) takes the shape of the letter U, there are two limits, therefore the promotion that is beneficial to described ball (70), and the end (73a) of described torsion spring (73) is stuck on described lock core (72), and the end (73b) of described torsion spring (73) reaches in the square hole of close apex of heart-shaped locked groove of lock core (72), and contact with described ball (70), described ball (70) is movably arranged in the axial elongated slot (71a) of position lock box shell (71) and the heart-shaped locked groove of lock core (72), and contact with the end (73b) of torsion spring (73) that is sleeved on lock core shaft (74) and reaches lock core (72), to be connected with the heart-shaped locked groove of lock core (72) and move up and down with the axial elongated slot (71a) of described position lock box shell (71), its target is put in place when the end (73b) that described ball (70) pushes away described torsion spring (73) and make the internal diameter of torsion spring Mi Quan become large, to unclamp the lock core shaft (74) being driven by pinion (9), make pipeline freely, and fall lock-bit when described ball (70), do not push away the end (73b) of described torsion spring (73), and the internal diameter of torsion spring Mi Quan is diminished, to pack tightly the lock core shaft (74) being driven by pinion (9), make pipeline motionless, thus be formed with, ball position is locked and the tube rolling device of many damping mechanisms, when pulling pipeline, because be equipped with joint (15) on main wheel (14), joint winds on described main wheel by tubulature line and pipeline, main wheel (14) is screwed is connected with lower wall (16), and by the large tubular axis in center of lower wall (16) rotationally kink be inserted on the smooth outer shaft table of center bassoon of lower casing (17), therefore upper deep bid (12), main wheel (14), pipe joint (15), lower wall (16) rotate with respect to shell, when pull-out pipeline, main wheel (14) drives pinion (9), when stopping drawing, described ball (70), because of clockwork spring reaction, is understood the eccentric heart-shaped locked groove (eccentric with ball catatrepsis in toilet bowl) that be provided with along described lock core (72), and is encountered heart-shaped recessed bottom, when ball enters, be the position of lock, be in locking, draw again and put and unclamp pipeline, without lock, under flexible pipe or the cable reaction force in clockwork spring (11), automatic rewinding, described have pressure-vaccum and pouring and fertilising and spill medicine and logatithmic spiral from the hay mover of brake holding, it is characterized in that;

    it is provided with logatithmic spiral brake and is provided with blower and is provided with and can be used for watering and applies fertilizer and spill the tube rolling device of the pipeline that passes through liquid of medicine, described brake, containing interior framework (76), installing motor (77) on described interior framework, on axle in described motor (77), be provided with motor pulley (84), and by belt (83), drive the belt wheel that cut disk center (204) of center line on chassis,And clutch connects the output shaft (203) of its concentric, and described output shaft (203) connection working tool is as hay knife;

    Described belt wheel (204) is fixed wtih one end of brake retracting spring (210) above with machine tooth screw (216), the other end of described brake retracting spring (210) be connected to the return pulling eye (225) of the brake bar (208a) of doing braking;

    Described brake bar (208a) be provided with rotation hole (226) and by rivet interlacement in belt wheel (204) and can flexible rotating;

    Described brake bar (208a) is provided with friction plate (209);

    Described interior framework is equiped with fixing brake ring (201a);

    The outer cover of described output shaft (203) is equipped with coaxial projection driver plate (227);

    The edge of described projection driver plate (227) is provided with projection and dials seat (224b);

    The edge of described projection driver plate (227) is also provided with reset seat (228), to reseting pressuring spring (228a) is installed and is resetted;

    Described projection is dialled on seat (224b) and is equipped with projection assembly (224a);

    Described brake bar (208a) is provided with the deep-slotted chip breaker hollowing out being surrounded by upper circular arc (224d), trough rim (224), lower circular arc (224c), another trough rim (224) successively;

    Described upper circular arc (224d) is semi arch, and the distance of its center of circle to described output shaft (203) axle center is distal to the center of circle of the described lower circular arc (224c) that is also semi arch to the distance in described output shaft (203) axle center, thus make the trough rim (224) of described deep-slotted chip breaker not along the concentric circumferences along output shaft axle center, but eccentric, this just forms substantial cam;

    Projection assembly (224a) on described projection driver plate (227) is inserted into described deep-slotted chip breaker and slides along described trough rim (224), this just forms substantial cam structure;

    During because of series excited machine stall, though have in series excited machine, electromagnetism is anxious to stop, and hay knife inertia disaster is anxious stops, and in order to make, hay knife is anxious stops meeting safety, just needs brake;

    When series excited machine stall, by described belt wheel (204) stall of driven by motor, then described brake bar (208a) loses the centrifugal inertial force of outwards throwing away, with described rotation hole (226) and rotated by rivet, and the return pulling eye (225) of the brake bar (208a) being connected to by described brake retracting spring (210) and go back to position, the fixing brake ring (201a) that the interior framework described in friction plate (209) brake holding that just makes described brake bar (208a) be provided with is equiped with;

    When described brake bar (208a) goes back to position, because described brake bar (208a) is provided with the deep-slotted chip breaker hollowing out being surrounded by upper circular arc (224d), trough rim (224), lower circular arc (224c), another trough rim (224) successively;

    And be semi arch because of described upper circular arc (224d), and the distance of its center of circle to described output shaft (203) axle center is distal to the center of circle of the described lower circular arc (224c) that is also semi arch to the distance in described output shaft (203) axle center, make the trough rim (224) of described deep-slotted chip breaker not along the concentric circumferences along output shaft axle center, but eccentricThis forms substantial cam;

    Projection assembly (224a) on the described projection driver plate (227) that is inserted into described deep-slotted chip breaker and slide along described trough rim (224) is pressed push described lower circular arc (224c) to according to substantial cam structure principle circular arc (224d) from described, because the outer cover of described output shaft (203) is equipped with coaxial projection driver plate (227), thus make working tool that described output shaft (203) be connected to as hay knife stall;

    Otherwise, when series excited machine rotates again, described belt wheel (204) by driven by motor rotates, the then centrifugal inertial force outwards thrown away of described brake bar (208a), taking described rotation hole (226) and by rivet as fulcrum turn-off, the friction plate (209) that just makes described brake bar (208a) be provided with leaves the fixing brake ring (201a) being equiped with on described interior framework, simultaneously, because the edge of described projection driver plate (227) is also provided with reset seat (228), mounted reseting pressuring spring (228a) is facilitated to reset;

    Described have pressure-vaccum and pouring and fertilising and spill medicine and logatithmic spiral from the hay mover of brake holding, be further characterized in that, it is provided with and can be used for watering and applies fertilizer and spill the tube rolling device of the pipeline that passes through liquid of medicine and the blower (229) being located on hay mover;
