Abstract
The invention discloses a self-help stalk puller, which comprises a spindle, travelling wheels rotatably disposed at two ends of the spindle, a handle bar, a foot bar, clamping blocks, drive blocks, a clamping block return elastic element and a foot bar return elastic element. Both the handle bar and the foot bar are rotatably connected with the spindle. The clamping blocks are rotatably and symmetrically disposed at one end of the handle bar. Each clamping block is provided with an outer clamping slope. The drive blocks are fixedly disposed at one end of the foot bar. Each drive block is provided with an inner drive slope in sliding connection with the corresponding clamping slope. The clamping block return elastic element is disposed between the two clamping blocks. The foot bar return elastic element is connected between the handle bar and the foot bar. The self-help stalk puller is simple in structure and easy to implement, free of oil consumption and electricity, and environment-friendly, and the efficiency of pulling stalks is improved for farmers.
Description
Technical field

Background technology
In recent years, continuous guiding along with the universal and national policy of agricultural mechanization, increasing people want to alleviate by farm implements the labour intensity of oneself, advance in living standard, the peasant who cultivates for small size especially, owing to using, big machinery harvesting cost is high, not easy to operate, very flexible, rests on the manual stage so go back so far majority, and manual operations equally also exists the shortcoming such as waste time and energy.The bar stem that comprises a lot of rigid posts stem of cotton stem crop is pulled out a great problem that operation becomes friend peasant.For this reason, we have designed the pole jack of the self-service use of peasant that a kind of applicable small size cultivates.
Summary of the invention
The object of the invention is that the bar stem that solves above-mentioned farmland bar stem crop pulls out problem, and a kind of self-service pole jack is provided, and specifically by following technical scheme, is realized.
A self-service pole jack, this self-service pole jack comprises main shaft, rotates a pair of road wheel, handlebar, foot-driven lever, two clamps, two drive blocks, clamp reseting elastic element and the foot-driven lever reseting elastic elements that are arranged on main shaft two ends; Described handlebar and foot-driven lever are all rotationally connected with main shaft middle part, described clamp is symmetricly set on handlebar one end rotationally, and this clamp outside is equipped with clamping inclined-plane, described drive block is fixedly installed on foot-driven lever one end, and this drive block inner side is provided with the driving inclined-plane being slidably connected with described clamping inclined-plane, described clamp reseting elastic element is arranged between two clamps, and described foot-driven lever reseting elastic element connects described handlebar and foot-driven lever.
Described self-service pole jack further designs and is, described clamp reseting elastic element is horizontally set between two clamps, the vertical connecting handle bar of described foot-driven lever reseting elastic element and foot-driven lever.
Described self-service pole jack further designs and is, described clamp reseting elastic element and foot-driven lever reseting elastic element are back-moving spring.
Described self-service pole jack further design is, described main shaft middle part is provided with support, and described support is provided with respectively foot-driven lever turning cylinder and the handlebar turning cylinder being rotationally connected with foot-driven lever and handlebar.
Described self-service pole jack further designs and is, described handlebar end is provided with locating clip, and this locating clip middle part is provided with clamp rotating shaft, and described clamp is rotated and is arranged in clamp rotating shaft by connecting rod respectively.
Described self-service pole jack further design is, is provided with mating holes in the middle part of described foot-driven lever, and described handlebar middle part is provided with bending part, and this bending part is through described mating holes.
Described self-service pole jack further designs and is, the other end that described handlebar is relative with clamp is provided with handle, and described foot-driven lever one end corresponding with handle is provided with pedal.
Described self-service pole jack further designs and is, described two clamps inner side is provided with corresponding horizontal direction interlock line.
The present invention keeps clamp not swing up and down by handlebar, pedal is downward, drive block rises, thereby drive block coordinates with inclined-plane between clamp, when making drive block increase, order about clamp and horizontally rotate and clamp crop bar stem, then pedal continuation is downward then to press down handlebar, handlebar is downward with pedal, under foot-driven lever and handlebar acting in conjunction, active force acts on crop bar stem at double, crop bar stem is pulled out, operation process has utilized lever principle, can easily crop bar stem be pulled out; The present invention is simple in structure, be easy to realize, and the present invention not oil consumption do not take electric environmental protection, effectively improved peasant's dead man operating efficiency.

Embodiment
Below in conjunction with Figure of description and specific embodiment, the present invention is further described
Contrast Fig. 1 and Fig. 4, this self-service pole jack comprises main shaft 1, rotate and be arranged on a pair of road wheel 2, handlebar 3, foot-driven lever 4 at main shaft two ends, two clamps 5, two drive blocks 6, clamp reseting elastic element 7 and foot-driven lever reseting elastic elements 8; Handlebar 3 and foot-driven lever 4 are all rotationally connected with main shaft 1 middle part, and main shaft 1 middle part is provided with support 11, and as shown in Figure 2, support 11 is provided with respectively foot-driven lever turning cylinder 41 and the handlebar turning cylinder 31 being rotationally connected with foot-driven lever 4 and handlebar 3.Foot-driven lever 4 middle parts are provided with mating holes 42, and handlebar 3 middle parts are provided with bending part 32, and bending part 32 is through mating holes 42.
In conjunction with Fig. 3, Fig. 4 and Fig. 5, handlebar 3 ends are provided with locating clip 33, and these locating clip 33 middle parts are provided with clamp rotating shaft 34, and clamp 5 is rotated and is arranged in clamp rotating shaft 34 by connecting rod 51 respectively.Clamp 5 inner sides are equipped with corresponding horizontal direction interlock line 53, its outside is equipped with and clamps inclined-plane 52, drive block 6 is fixedly installed on foot-driven lever 4 one end, and these drive block 6 inner sides are provided with and the driving inclined-plane 61 that clamps inclined-plane 52 and be slidably connected, (in figure for two inclined-planes are indicated clear, both are contact not, and in fact both keep being slidably connected under the effect of clamp reseting elastic element.) clamp reseting elastic element 7 is horizontally set between two connecting rods 51, the vertical connecting handle bar 3 of foot-driven lever reseting elastic element 8 and foot-driven lever 4.Clamp reseting elastic element 7 and foot-driven lever reseting elastic element 8 can be the reseting elastic elements such as spring or torsion spring, so that each several part resets in time to pull out operation next time.The other end that handlebar 3 is relative with clamp 5 is provided with handle 35, and foot-driven lever 4 one end corresponding with handle 33 is provided with pedal 43.
This self-service pole jack is when operation, promoting this self-service pole jack makes clamp 5 corresponding with crop bar stem, operator holds handle 35, trample pedal 43 downwards, the drive block 6 that is arranged on foot-driven lever 4 other ends is moved upward, thereby drive inclined-plane 61 and clamp inclined-plane 52 sliding frictions, make clamp 5 clamp crop bar stem to middle gathering, press down handlebar 3 simultaneously, thereby make to lift crop bar stem is pulled out on clamp 5 one end.After this, clamp 5 opens under the effect of its corresponding back-moving spring, and also homing under its corresponding action of reset spring of foot-driven lever 4.The back-moving spring of foot-driven lever has guaranteed that foot-driven lever 4 is not having under the situation of External Force Acting simultaneously, and its two ends all can not offset with ground.
