Abstract

The invention relates to a cotton straw pull-out device which comprises a base, a main frame, a pedal, a rope and a straw pull-out clamp, wherein the base is a flat casting plate; the main frame is a nonmetal part and is connected on the base through a screw; a sliding block is assembled on the main frame through a dovetail groove; the straw pull-out clamp can slide vertically under the traction effect of the rope; welding assemblies such as displacement supports and displacement rings are assembled at the other two opposite sides of the main frame and facilitate displacement during work; one end of the rope is connected with the sliding block, and the other end is connected with the pedal and can slide back and forth in a sliding slot of a rope support pulley assembly; and the pedal is connected on the based through a screw and a hinge. During work, when the pedal is pressed down, the straw pull-out clamp is driven by the traction of the rope, so that a clamped cotton straw is pulled out upwards; and when the pedal is released, the pedal returns to the initial state due to the gravity action of the sliding block and the straw pull-out clamp. The cotton straw pull-out device is compact and reasonable in structure, moderate in weight and convenient to displace; the foot-operated mode can save physical energy of a user; and the operation is convenient and reliable. Thus, the cotton straw pull-out device can be popularized and applied conveniently.

Description

Cotton straw plucking device

Affiliated technical field

The present invention relates to a kind of farming device, especially relate to cotton straw plucking device.

Background technology

The rural area person between twenty and fifty go out to work and increase, so stay-at-home peasant's astogeny becomes universal phenomenon, during the pulling out of cotton straw, are pulled out by manual fully, and labour intensity is large, the elderly's hypodynamia; Use the agricultural machinery automation to pull out, the elderly's operating difficulties needs a kind of foot-operated cotton straw plucking device.Cotton straw plucking device mainly comprises base, body frame, and pedal, rope, stalk is pulled out folder etc., realizes that the pedal semiautomatic of cotton knot is pulled out function.

At present, pulling out of cotton straw finished if rely on by hand fully, and labour intensity is large, and efficient is low; If use the agricultural machinery automation to finish, complex structure, operating difficulties, cost is high; If use the semimechanized plucking device of hand, utilize the operation of hand strength to finish, labour intensity is also larger.

Summary of the invention

In order to overcome in the pulling out of existing cotton straw, complete manual finishing, labour intensity is large, and efficient is low; The agricultural machinery automation is finished, complex structure, and operating difficulties, cost is high; Semimechanized plucking device is mainly finished by hand strength operation based on lever principle, and labour intensity is the defective such as larger also, the invention provides the cotton straw plucking device of pedal semiautomatic.

The present invention specifically solves the technical solution that its technical problem adopts: the cotton knot plucking device comprises base 10, and body frame 11, slide block 12, stalk are pulled out folder 13, rope supports

pulley assembly

14A, 14B, rope 15, pedal 16, hinge 17 is moved and is supported 20A, 20B, moves ring 21A, 21B.Base 10 is plate casting, and body frame 11 is nonmetal parts, by screw attachment on base 10.Body frame 11 1 sides have the certain-length dovetail groove, and slide block 12 is assemblied on the body frame 11 by dovetail groove, pull out folder 13 by rope 15 traction drive stalks and slide up and down.Body frame 11 other two offsides are threaded connection assembling and move the weld assembly that supports 20A, 20B and move ring 21A, 21B.The upper surface of body frame 11 is equipped with rope and is supported

pulley assembly

14A, 14B, rope 15 moderate length, and an end connection sliding block 12, the other end connects pedal 16, and the slippage groove that supports

pulley assembly

14A, 14B at rope slidably reciprocates.Pedal 16 is connected on the base 10 by screw and hinge 17, during lower pedal 16, drive stalk by rope 15 tractions and pull out folder 13 upward slidings, released the pedal 16 o'clock, because slide block 12 and stalk are pulled out the Action of Gravity Field of folder 13, pedal 16 is returned to original state by rope 15 tractions.

The invention has the beneficial effects as follows, adopt the cotton straw plucking device of pedal semiautomatic, solved complete craft and finished, labour intensity is large, and efficient is low; The agricultural machinery automation is finished, complex structure, and operating difficulties, cost is high; The semimechanized plucking device of hand, labour intensity be the problem such as larger also, and its compact conformation is reasonable, and weight is moderate, moves the aspect, and pin is stepped on the muscle power that mode is saved the user, and operation is convenient reliable.
