technical field

The invention relates to the field of agricultural implements, in particular to a self-service pole pulling machine.

Background technique

In recent years, with the popularization of agricultural mechanization and the continuous guidance of national policies, more and more people want to use farm tools to reduce their labor intensity and improve their living standards, especially for small-scale farmers. The cost is high, it is not easy to operate, and the flexibility is poor. So far, most of them are still in the stage of manual operation. Manual operation also has the disadvantages of time-consuming and labor-intensive. The removal of stems of many hard stem crops, including cotton stems, has become a major problem for farmers. For this reason, we have designed a kind of rod puller that is suitable for the self-service use of farmers who cultivate in small areas.

The further design of the self-service rod pulling machine is that the clamping block return elastic element is horizontally arranged between two clamping blocks, and the foot lever return elastic element vertically connects the handle bar and the foot bar.

The further design of the self-service rod pulling machine is that the clamping block reset elastic element and the pedal rod reset elastic element are both return springs.

The further design of the self-service rod pulling machine is that a bracket is provided in the middle of the main shaft, and the rotation shaft of the pedal rod and the rotation shaft of the handle rod are respectively connected to the pedal rod and the handle rod in rotation on the bracket.

The further design of the self-service rod pulling machine is that the end of the handle rod is provided with a positioning clip, and the middle part of the positioning clip is provided with a clamping block rotating shaft, and the clamping blocks are respectively arranged on the clamping block rotating shaft through connecting rods. .

The self-service rod pulling machine is further designed in that a matching hole is provided in the middle of the pedal rod, and a bending part is provided in the middle of the handle rod, and the bending part passes through the matching hole.

The self-service rod pulling machine is further designed in that a handle is provided at the other end of the handle rod opposite to the clamping block, and a pedal is provided at the end of the pedal rod corresponding to the handle.

The further design of the self-service rod pulling machine is that the inner sides of the two clamping blocks are provided with corresponding horizontal engagement lines.

The invention uses the handle bar to keep the clamping block from swinging up and down, the pedal goes down, the driving block rises, and the slope between the driving block and the clamping block cooperates to make the driving block rise and at the same time drive the clamping block to rotate horizontally to clamp the crops Then press down the handle rod and then the pedal continues downward, the handle rod goes down with the pedal, under the joint action of the pedal rod and the handle rod, the force doubles on the crop stem, and the crop rod Stem removal, the operating process utilizes the principle of leverage, which can easily remove the stems of crops; the invention has a simple structure, is easy to implement, and the invention consumes no fuel and electricity, is green and environmentally friendly, and effectively improves the efficiency of farmers' rod removal operations.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments of the specification

1 and 4, the self-service rod pulling machine includes a main shaft 1, a pair of walking wheels 2 rotated at both ends of the main shaft, a handle bar 3, a pedal bar 4, two clamping blocks 5, two driving blocks 6, The clamping block resets the elastic element 7 and the pedal lever resets the elastic element 8; the handle bar 3 and the pedal lever 4 are all rotatably connected with the middle part of the main shaft 1, and the middle part of the main shaft 1 is provided with a bracket 11. As shown in Figure 2, the bracket 11 is provided with Have the pedal lever rotating shaft 41 and the handle lever rotating shaft 31 that are rotationally connected with the pedal lever 4 and the handle lever 3 respectively. A matching hole 42 is provided in the middle of the pedal rod 4 , and a bending portion 32 is provided in the middle of the handle rod 3 , and the bending portion 32 passes through the matching hole 42 .

3, 4 and 5, the end of the handle rod 3 is provided with a positioning clip 33, and the middle of the positioning clip 33 is provided with a clamping block rotating shaft 34, and the clamping block 5 is respectively rotated and arranged on the clamping block rotating shaft through a connecting rod 51. 34 on. The inner sides of the clamping blocks 5 are provided with corresponding horizontal occlusal lines 53, and the outer sides are provided with clamping slopes 52. The driving block 6 is fixedly arranged on one end of the pedal rod 4, and the inner side of the driving block 6 is provided with a clamping surface. The driving slope 61 of the sliding connection of the slope 52, (in order to clearly mark the two slopes in the figure, the two are not in contact. In fact, the two remain slidingly connected under the action of the clamping block reset elastic element.) The clamping block resets the elastic element 7 is horizontally arranged between the two connecting rods 51, and the pedal rod return elastic element 8 is vertically connected to the handle rod 3 and the pedal rod 4. Clamping block reset elastic element 7 and pedal lever reset elastic element 8 can be reset elastic elements such as spring or torsion spring, so that each part resets in time so that pull out operation next time. The other end of the handle bar 3 opposite to the clamping block 5 is provided with a handle 35 , and the end of the pedal bar 4 corresponding to the handle 33 is provided with a pedal 43 .

When the self-service rod pulling machine is in operation, the self-service rod pulling machine is pushed to make the clamping block 5 correspond to the crop stem. The drive block 6 at one end moves upwards, thereby driving the inclined surface 61 to slide and rub against the clamping inclined surface 52, so that the clamping block 5 gathers the crop stems inwardly, and simultaneously presses down the handle bar 3, so that one end of the clamping block 5 is lifted up so that Pull out the crop stems. Thereafter, the clamping block 5 is opened under the action of its corresponding return spring, and the pedal rod 4 is also returned to its original position under the action of its corresponding return spring. Simultaneously the back-moving spring of pedal rod has guaranteed that pedal rod 4 is under the situation that does not have external force, and its two ends all can not be offset with ground.
