Abstract

The utility model relates to a cotton-stalk pulling-up device which is composed of a clamping body, a lever, a rotary shaft, rolling wheels, springs, etc. The clamping body is matched with the lever by the rotary shaft, and the springs which respectively act on the lever and the clamping body are arranged on the rotary shaft. The rolling wheels are matched with the lever by a bracket. When a cotton stalk enters the jaw opening of the clamping body, a handle is pressed downwards to cause the lever to be operated. The clamping body is pressed to be turned axially to automatically clamp the cotton stalk until the cotton stalk is pulled up. The handle is lifted, the clamping body is turned reversely by spring force to cause the cotton stalk to be unclamped, and the utility model complete the work that the cotton stalk is pulled up. The utility model has simple structure, reliable work, convenient operation and labor saving, and the utility model can lighten cotton growers' work.

Description

Cotton-stalk pulling-up device

The utility model relates to a kind of utensil of the plant stalk of choosing, particularly Device for pulling up cotton stalks.

China is Cotton Production big country, and most places still are the production of peasant's mode, pulls out cotton stalk and relies on manual carrying out mostly, and minority relies on clumsy aid, and the cotton stalk of thick shape also needs take by hoe, hoe, and is time-consuming, labour intensity is big, efficient is low.

The purpose of this utility model is, at above-mentioned the deficiencies in the prior art, improves, and proposes and design a kind of Device for pulling up cotton stalks.A kind of new utensil is provided for the work pull out cotton stalk, can alleviates the labour intensity that carries out this work, increase work efficiency, make can not serve as originally pull out cotton stalk work the old and the weak labourer by this utensil, also can finish the work of pulling out cotton stalk.

Technical solution of the present utility model is, adopts cramping body, lever, roller, it is characterized in that cramping body connects by rotating shaft and lever, and spring is installed in the rotating shaft, and both ends of the spring cooperates with lever and cramping body respectively, and roller is joined company by support and lever.

Cramping body is installed in the lower end of lever by rotating shaft.

The upper end of lever is fitted with handle.

Support cooperates with two rollers by wheel shaft.

Support, wheel shaft, roller constitute the fixed pivot of lever.

Operation principle of the present utility model is, cramping body is used for clamping and loosening cotton stalk, and lever is used for transmitting operating physical force and has laborsaving function, roller for lever keeping of providing that a convenience moves balance with strong point suitable height.Enter the jaw of cramping body when cotton stalk after, the handle of operator's depress lever upper end, which limit of jaw no matter cotton stalk is run into cramping body, because the effect of frictional force, the effect of the operating physical force that cramping body is applied will produce around axial rotation and with the cotton stalk clamping, until cotton stalk is pulled up, mention handle, under the acting in conjunction of the active force of spring and lever gravity, cramping body produces and oppositely pivots, and cotton stalk is unclamped, cotton stalk can break away from cramping body, thereby finishes the work of pulling out cotton stalk.

Advantage of the present utility model is, for the work of pulling out cotton stalk provides a kind of effective instrument, pulling out cotton stalk now is to adopt by hand mostly, both hands are held cotton stalk, directly choose, not by effective tool, non-able-bodied laborer is not competent, use the utility model, alleviated hand labour, avoided coarse cotton stalk adversary's wearing and tearing, simultaneously because lever moving arm is longer than resistance arm, can be laborsaving 70%, improve work efficiency 3-5 doubly, also since the strong point in the lever middle and lower part, changed application of force direction, make body weight change power, and avoided bending over moving and saved muscle power greatly, thereby make the old and the weak labourer also can be competent at this work by resistance, so of the present utility model applying, can alleviate cotton grower's work, improve the condition of its work, of the present utility model simple and reasonable, easy to use, only utilize pressing down and mentioning action of lever, can finish clamping the action of loosening cotton stalk, finish the action of pulling out cotton stalk simultaneously.The utility model is rational in infrastructure, and is economical and practical, makes simply, is suitable for universal.

Describe embodiment of the present utility model below with reference to the accompanying drawings in detail.

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, the utility model is made up of rotating shaft 1, cramping body 2, lever 3, wheel shaft 4, support 5, roller 6, handle 7, spring 8.Cramping body 2 connects together by rotating shaft 1 and lever 3, a spring 8 is housed in the rotating shaft 1, spring 8 two ends cooperate with lever 3 and cramping body 2 respectively.Have on the cramping body 2 and block and the fixing jaw of cotton stalk, spring 8 is a torque spring, two rollers 6 that are contained in wheel shaft 4 two ends support 5 by connecting with wheel shaft 4, connect with lever 3, for providing a convenience, moves the utility model, and can keep the fixed pivot of balance, and to deviate from from wheel shaft 4 ends in order to prevent roller 6, wheel shaft 4 ends are equipped with fixing card 10.Support 5 is furnished with fixing card 9 with the position that wheel shaft 4 connects.Cramping body 2 is installed in the bottom of lever 3 by rotating shaft 1, and is because the effect of spring 8 makes cramping body 2 and lever 3 keep set angles, promptly parallel to the ground.The position that support 5 and lever 3 connect is in the middle and lower part of lever 3, this is for convenience laborsaving, handle 7 is equipped with in lever 3 upper ends, is convenient to hand operated, further specifies the course of work of this utility model according to Fig. 5, under free state, be subjected to the jacking of spring 8 elastic force below the cramping body 2, be subjected to the restriction of lever 3 boss above, and with the ground keeping parallelism, at this moment, the vertical projection size maximum of the width of jaw L of cramping body 2.Equal L.And cramping body 2 is when rotating, and vertical projection size will reduce gradually, until being zero.After cotton stalk entered in the jaw of cramping body 2, handle 7 places of depress lever 3 then made an end of the lever 3 that cramping body 2 is housed rise, because the effect of the frictional force between jaw and the cotton stalk, make that cramping body 2 is stressed 1 to be rotated down around the shaft, at this moment the vertical projection size of width of jaw constantly dwindles along with the increasing of the anglec of rotation, when its during less than the cotton stalk diameter d, just cotton stalk is clamped, stop the rotation, until cotton stalk is pulled up, otherwise when mentioning handle 7, then reversely carry out above-mentioned action.Cramping body 2 restores under the effect of the torsion of spring 8, turns to previous status and parallel to the ground again, so just unclamps cotton stalk, has finished the overall process of pulling out cotton stalk.

Lever 3 can adopt bar material or tubing processing and fabricating.
