The technological deficiency that to-and-fro motion location locking in farm machinery of the present utility model exists, provides a kind of and can realize electric control for opening lock for reciprocating electric control for opening lock Ji Tiao mechanism, and reliable and stable, cost of production is low.
The utility model adopts following technological scheme to realize: a kind of reciprocating electric control for opening lock Ji Tiao mechanism, comprise and do the reciprocal tooth bar 6 of linear reciprocating motion and swingable ratchet 5, the increment of described ratchet 5 is close to and is engaged with the unidirectional ratchet on reciprocal tooth bar 6 by spring 7, the top of described ratchet 5 is installed with the electromagnet 4 of absorption ratchet 5, realizes and separates release with reciprocal tooth bar for adsorbing ratchet.
Concrete, the locking limit 61 of the unidirectional ratchet on described reciprocal tooth bar 6 swings tangential with the increment of described ratchet 5.
Further, described electromagnet 4 is fixedly installed on fixing frame 3, and described fixing frame 3 is fixed on the top of described ratchet 5 by set screw 2.
Further, described ratchet 5 belows are provided with stop screw 8, for locate ratchet when the locking with the reciprocal unidirectional ratchet correct engagement of tooth bar.
In the utility model, described ratchet 5 is made for magnetic material, is convenient to the absorption of electromagnet to ratchet.
Electric control for opening lock Ji Tiao of the present utility model mechanism is by the reciprocal tooth bar of magnet control ratchet release, convenient for unlocking, reliability are high, and can realize remote operation and automatically control, can extensive use and farm machinery in need reciprocating mechanism, be conducive to promote the process of agricultural machinery automation.
Below in conjunction with the drawings and specific embodiments, the utility model is described further.

Embodiment
Embodiment
Referring to Fig. 1, the reciprocating electric control for opening lock Ji Tiao of one mechanism, comprise and do the reciprocal tooth bar 6 of linear reciprocating motion and swingable ratchet 5, the increment of described ratchet 5 is close to and is engaged with the unidirectional ratchet on reciprocal tooth bar 6 by spring 7, spring 7 one end are fixed, and the other end is connected with the middle part of ratchet 5.The top of described ratchet 5 is installed with the electromagnet 4 of absorption ratchet 5, realizes and separates release with reciprocal tooth bar for adsorbing ratchet.Described electromagnet 4 is fixedly installed on fixing frame 3, and described fixing frame 3 is fixed on the top of described ratchet 5 by set screw 2.Described ratchet 5 belows are provided with stop screw 8, for locate ratchet when the locking with the reciprocal unidirectional ratchet correct engagement of tooth bar.Described ratchet 5 is made for magnetic material, is convenient to the absorption of electromagnet to ratchet.
The locking limit 61 of the unidirectional ratchet on described reciprocal tooth bar 6 swings tangential with the increment of described ratchet 5, as shown in Figure 2, ratchet 5 is 90 ° to the locking power F of reciprocal tooth bar 6 with the angle on the locking limit 61 of reciprocal rack ratchet, and locking power F, perpendicular to locking limit 61, can ensure that locking is reliable.Back and forth the locking limit 61 of the unidirectional ratchet of tooth bar 6 is tangent to the circular arc line that separates the swing of solution lock-bit from locking with ratchet, in the time of release, ratchet 51 swings around the shaft, ratchet increment is 0 with the resistance of the point of contact tangent direction on the locking limit of reciprocal tooth bar, and electromagnet can easily separate release by ratchet 5 with the unidirectional ratchet of reciprocal tooth bar.
Taking bridge-type leaf cutter for tobacco seedlings as example, in the to-and-fro motion of leaf shearing device, back and forth tooth bar 6 is connected with the reciprocator of leaf shearing device, back and forth tooth bar 6 passes from fixing frame 3 below left ends, when back and forth the unidirectional ratchet on tooth bar 6 is towards left movement, ratchet 5 is backed down counterclockwise, back and forth tooth bar can pass through by right-to-left smoothly, and ratchet 5 exists the power swinging clockwise under spring 7 pulling force effects, the increment of ratchet 5 is close to and is engaged all the time in the direction towards right with unidirectional ratchet, the motion of turning right of the reciprocal tooth bar 6 of locking.In the time that leaf shearing device arrives Miao Chi end, need to stop to-and-fro motion, then leaf shearing device forward a mobile station carry out back and forth pruning of next one, in the process of leaf shearing device reach, the increment of ratchet 5 props up the locking limit 61 of unidirectional ratchet on reciprocal tooth bar 6, leaf shearing device is located to locking, prevent laterally travelling backwards in moving process.
In the time that leaf shearing device need to move back and forth again, back and forth tooth bar 6 need to be turned left from the right side while exiting, electromagnet 4 is switched on, the magnetic force that electromagnet 4 produces produces suction to ratchet 5, make ratchet 5 counter-clockwise swings, ratchet 5 is held by electromagnet 4, and ratchet 5 separates with the unidirectional ratchet of reciprocal tooth bar, and back and forth tooth bar 6 can move right.
The leaf shearing device of bridge-type leaf cutter for tobacco seedlings utilizes the horizontal intermittently reciprocating locking that keeps to the side of above-mentioned electric control for opening lock sour jujube bar winding machine, can utilize automatic control and remote electrically controlled release, convenient and swift, can keep keeping to the side to stop the scheduled time in efficient to-and-fro motion discontinuous by effective guarantee leaf cutter for tobacco seedlings, so that leaf shearing device can not leak the cigarette seedling of cutting seedling pool side edge, be conducive to use manpower and material resources sparingly, realize efficient control automatically.
Above-mentioned is preferred implementation of the present utility model; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; the various variations of in form and details the utility model having been done, all belong to protection domain of the present utility model.
