Abstract

The utility model discloses a clamp type corn row crop thinner. A handle is vertically fixed with a bearing rod on which a clamping arm is hinged, a movable clamping plate is fixedly connected together with the clamping arm and a stationary clamping plate is fixed at the lower end of the bearing rod. One end of a tension spring is connected to the supporting rod, and the other end is connected with the clamping arm. A limit stop is fixed on the bearing rod, and the head of the stationary clamping plate is designed into a sawtooth shape. One end of a pull rope is connected with the clamping arm, and the other end is connected to a tension ring. The clamp type corn row crop thinner is used for replacing human power for manual thinning, enables people to once root up excess seedlings when people walk in standing postures, and has the advantages of time saving, labour saving, simple structure and flexible operation with convenience.

Description

Jaw clamping type corn blocker

Affiliated technical field

The utility model relates to a kind of jaw clamping type corn blocker, belongs to agricultural machinery manufacturing technology field.

Background technology

At present, no matter Maize Production adopts by artificial seeding or mechanical planting, is hole kind mode, 3 ± 1 of every hole sowings, when growing to five leaf left and right sides, begin thinning, every cave field planting one strain, application and thinning-out method mainly is the manual thinning of manpower, face the loess quilt towards the sky, labour intensity is very big, and efficient is low, seriously seedling is pulled off because of root system dish knot sometimes, residual fraction also needs to go to dig with finger, even finger can be galled.

Summary of the invention

The utility model provides a kind of jaw clamping type corn blocker at the problems referred to above, in order to replace the manual thinning of manpower, can make that people are disposable in the walking of standing to be torn up by the roots unnecessary seedling, and is time saving and energy saving.

Task of the present utility model is finished as follows: with handle and pole vertical fixing, jig arm is articulated on the pole, moving clamping plate are fixedlyed connected with jig arm and are integral, decide clamping plate and be fixed in the pole lower end, one end of extension spring is connected on the pole, and the other end is connected on the jig arm, and positive stop is fixed on the pole, one end of stay cord links to each other with jig arm, and the other end links to each other with draw ring; The described clamping plate head design of deciding is a zigzag fashion.

When the utility model uses, finger passes draw ring, grasp handle, to decide clamping plate and insert the seedling root, move upward with the finger pull draw ring,, overcome the pulling force of extension spring simultaneously by stay cord pulling jig arm, make clamping plate to deciding the close and closed gradually exposed portions serve that clamps seedling of clamping plate, then complete machine is mentioned, seedling is pulled out, and loosens draw ring, jig arm is under the effect of extension spring, fixed, moving clamping plate separate, and seedling falls automatically, thereby finishes a working cycles, decide the clamping plate head and adopt zigzag fashion, can reduce to insert resistance and also can avoid injuring the root of deciding young plant, the utility model is simple in structure, flexible and convenient operation.
