Abstract
Machinery manufacturing technology field, to solve the problems, such as that existing corn picker can be with automatic measurement Row spacing of maize during harvest, the utility model provides a kind of structure of the new measurement Row spacing of maize with extension type, including servomotor, rack, ball-screw, feeler lever, it is characterized in that, the rack one side connects motor, ball-screw is connected positioned at the rack opposite side, a sliding block is connected on the ball-screw, a U-type groove is connected above the sliding block, a feeler lever is connected positioned at the U-type groove.The utility model is simple in structure, ingenious in design, at low cost, can effectively solve the problem that maize harvesting machine can be with the problem of automatic measurement line-spacing.
Description
Technical field
The utility model is related to machinery manufacturing technology field, more particularly to a kind of new measurement corn with extension type
The structure of line-spacing.
Background technology
Harvester is in different regions operation, since the line-spacing of corn is different, the very easy jade planted due to different user
Rice line-spacing is different, results in the need for the line-spacing of manual adjustment maize harvesting machine, reduces the work efficiency of harvester.
Utility model content
In order to overcome above-mentioned technical problem, the utility model provides a kind of new measurement corn row with extension type
Away from structure.
Technical solutions of the utility model are：A kind of structure of the new measurement Row spacing of maize with extension type, including watching
Take motor, stepper motor, rack, ball-screw, feeler lever, which is characterized in that one rack of connection, institute below the servomotor
The other end connection ball-screw of rack is stated, the range unit that rack moves back and forth where driving ball-screw stretches, the rolling
The top of ballscrew connects a sliding block, and the upside of the sliding block connects a U-type groove, has travel switch can inside the U-type groove
It is counter when it encounters plant to make by one feeler lever of pin connection inside the U-type groove for controlling stepper motor rotating
With to travel switch.
The beneficial effects of the utility model are：
A kind of structure of the new measurement Row spacing of maize with extension type of the utility model, is measured using travel switch and visited
Whether bar touches plant, and the rotating for controlling motor by control system further controls moving left and right for feeler lever, leads to
The spacing of encoder measurement corn is crossed, the utility model is simple in structure, ingenious in design, at low cost, can effectively improve harvester and exist
The efficiency of corn spacing is measured during harvest.

Specific embodiment
With reference to Figure of description 1 to the new measurement Row spacing of maize with extension type a kind of to the utility model of attached drawing 4
Structure, be described in detail below.
It is a kind of new with a kind of structure of the new measurement Row spacing of maize with extension type, including servomotor 9, step
Stepper motor 1, rack 8, ball-screw 3, feeler lever 2, which is characterized in that 9 one rack 8 of lower section connection of servomotor, it is described
The other end connection ball-screw 3 of rack 8, servomotor 9, which rotates to move back and forth with carry-over bar 8, drives 3 place of ball-screw
Range unit stretches, and the top of the ball-screw connects a sliding block 4, and the upside of the sliding block 4 connects a U-type groove 7, described
There is travel switch 5 to can be used to control 1 rotating of stepper motor inside U-type groove 7, pass through the connection of pin 6 one inside the U-type groove 7
Feeler lever 2, reaction is to travel switch 5 when it encounters plant.
A kind of structure of the new measurement Row spacing of maize with extension type passes through control mechanism（PLC）Accurately controlled
Whether system encounters plant using travel switch detection feeler lever, and the rotating for controlling stepper motor by control system controls
The spacing for moving left and right detection plant of feeler lever, so as to which achieve the effect that can be with automatic measurement plant spacing.
The above, is only specific embodiment of the present utility model, and those skilled in the art are new in this practicality
In the range of type discloses, the variation that can readily occur in should all be covered within the scope of the present invention.
