The invention discloses a prying share, which comprises a share head and is characterized by also comprising: the lower side of the lever is fixedly connected with the upper side of the ploughshare head; a pin shaft hole is arranged at the front end of the lower end 1/3 of the lever; a fulcrum frame movably connected with the pin shaft hole through a pin shaft. The fulcrum frame comprises two bracket arms, and the front ends of the two bracket arms are provided with arm holes corresponding to the bracket arm pin holes and the pin shafts; the rear sides of the two frame arms are provided with pedals. The prying ploughshare has small volume, simple structure, convenient carrying, no need of external power and low cost. When the ploughshare is in work, the ploughshare head is punched and inserted into the ground in the middle of the hand-held lever, then the lever is pressed downwards backwards and downwards, the pedal plate of the fulcrum frame is stepped on by one foot, the pedal plate is pressed downwards continuously by taking the pin shaft of the fulcrum frame as a fulcrum, and the fulcrum is arranged at the front end of the lower end 1/3 of the lever, and the power arm is larger than the negative force arm, so that the soil on the ploughshare head below can be pried by small pressing force, and the action of ploughing can be achieved by continuously repeating the action. Is beneficial to the farming of the plowed land and is suitable for the plowed land.

Description

Prying ploughshare

Technical Field

The invention relates to an agricultural implement, in particular to a ploughshare for plowing soil.

Background

The prior ploughshare for plowing soil is generally triangular and is used as a sharp tool of a breaker and arranged at the front end of the plough; the plough needs to be driven by manpower, animal power or machine power, breaks the soil and turns over the cultivated land in the forward movement, and has large volume, complex structure and high cost.

Disclosure of Invention

The invention aims to provide a prying ploughshare which is small in size, simple in structure and low in cost.

In order to achieve the purpose, the technical scheme of the invention is as follows:

a prying share comprises a share head and is characterized by further comprising:

the lower side of the lever is fixedly connected with the upper side of the ploughshare head;

a pin shaft hole is arranged at the front end of the lower end 1/3 of the lever;

a fulcrum frame movably connected with the pin shaft hole through a pin shaft.

The fulcrum frame comprises two bracket arms, and the front ends of the two bracket arms are provided with arm holes corresponding to the bracket arm pin holes and the pin shafts; the rear sides of the two frame arms are provided with pedals.

The prying ploughshare with the structure is small in volume and simple and convenient to carry, the middle of the lever is held by a hand to enable the ploughshare head to be inserted into the ground, then the lever presses downwards backwards and downwards, the pedal of the fulcrum frame is stepped on by one foot, the pin shaft of the fulcrum frame is taken as a fulcrum to continue pressing downwards, the fulcrum is arranged at the front end of the lower end 1/3 of the lever, and the power arm is larger than the negative force arm, so that the soil on the ploughshare head below can be pried by very small pressing force, and the action of plowing can be achieved by continuously repeating the action. Moreover, the prying ploughshare only comprises the ploughshare head, the lever and the fulcrum frame, has simple structure and low manufacturing cost, is beneficial to the farming of soil turning and ploughing and promotes the production.

in the figure, a share head 1, a pin shaft 2, a lever 3, a fulcrum frame 4, a pin shaft hole 5, a pedal plate 6, a bracket arm 7, an arm pin hole 8, a three-tooth share head and a five-tooth share head 9.

Detailed Description

The invention will be further described with reference to the accompanying drawings.

Fig. 1 is a schematic perspective view of the invention, which is combined with the schematic structural view of the ploughshare head and the lever in fig. 3 and the schematic structural view of the fulcrum frame in fig. 3, and the invention comprises the ploughshare head 1, the lever 3 and the fulcrum frame 4. As can be seen from the figure, the upper edge of the share head 1 is fixedly connected with the lower edge of the lever 3; the front end of the lower end 1/3 of the lever 3 is provided with a pin shaft hole 5 which is parallel to the plane of the share head 1; the fulcrum frame 4 comprises two parallel bracket arms 7, a bracket arm pin hole and a pedal, wherein the front ends of the two bracket arms 7 are provided with arm pin holes 8 corresponding to the pin shaft 2 and the pin shaft hole 5; a pedal 6 is fixed at the rear of the two frame arms 7. The lever 3 containing the pin shaft hole 5 is clamped between two parallel frame arms 7, the pin shaft hole 5 is communicated with the arm pin hole 8 and the pin shaft 2 can be placed in the pin shaft hole 5, the pin shaft 2 is movably connected with the arm pin hole 8 and the pin shaft hole 5, so that the pivot frame 4 can be flexibly paved on the ground when the plowing land descends, an operator can step on the pedal plate 6 to position the pivot of the lever, and when the lever 3 descends backwards and downwards, the share head 1 at the lower end can pry and turn the land with less effort due to the action of the lever principle, and the farming is facilitated.

Fig. 4 and 5 are enlarged schematic views of the three-tooth and five-tooth ploughshares and levers, and it can be seen from the drawings that the ploughshare can also be of a three/five-tooth structure, i.e. the ploughshare of the three-tooth structure and the ploughshare of the five-tooth structure replace the single-tooth ploughshare 1 in fig. 1, and other structures and working principles are the same as those of the single-tooth sled ploughshare shown in fig. 1-3, while the ploughshare of the three-tooth structure/the ploughshare of the five-tooth structure can be used for turning more areas of land, so that the efficiency is higher, but the labor saving effect is slightly lower. Of course, the ploughshare head can be arranged into 2, 4, 6 and other multi-tooth ploughshare heads, and the application is just needed.

The working principle of the invention is as follows:

the ploughshare head is downward, the middle part of a lever 3 holding the prying ploughshare by hand is lifted up and is pushed down to the ground to be turned, the lever 3 is slightly pushed downward after the ground is punched, the ploughshare head 1/9/10 at the lower end can pry up the ground to turn the soil, or if the ground is harder, a pedal 6 of a pedal support 4 is stepped, the prying ploughshare takes a pin shaft 2 as the fulcrum of the lever 3, the lower end of the fulcrum of the lever 3 is a resistance arm, the upper end is a power arm, the upper end of the lever 3 is pressed by hand, and the hard ground is very easy to turn up; or the ground is not firm, the share head 1/9/10 is rushed into the ground, the upper end of the lever 3 is slightly pressed behind the hand to incline the lever, and then the lever 3 is held by the hand to rush forwards to turn out a ditch-shaped land. And repeating the step of turning the soil, thereby completing the work of turning the soil and ploughing. The invention has simple structure, small volume, low cost and only manual operation without external power.
