Description

Improved R types pin

Technical field

It the utility model is related to a kind of R types pin.

Background technology

Rotary cultivator is the cultivation machinery for completing to plough, harrow operation with tractor.Because it has, hack ability is strong, ploughs rear ground The features such as table is flat, and be widely used；The root stubble being embedded in below earth's surface can be shredded simultaneously, is easy to seeder to make Industry, good kind bed is provided for later stage sowing.

Rotary cultivator includes frame, the gearbox being arranged in frame, the rotary tillage shaft being arranged on below frame, and gearbox is with dragging The power output axis connection of machine drawing, the front of frame are provided with the two lower draw rod attachment parts in left and right, and the rear of rotary cultivator is provided with bonnet Plate, back shroud one end are hinged on the rear end of frame, and the other end of back shroud is connected to the draw-bar seat in frame, pull bar by pull bar One end is hinged on back shroud, and the other end of pull bar is slidably arranged on draw-bar seat, on the pull bar between draw-bar seat and back shroud Spring is arranged with back shroud to be compressed on the ground, pull bar bottom is provided with spring adjustment mechanism to adjust the pressure of spring.

Need to get into when changing rotary blade below cutter shaft or operated between rotary cultivator and tractor, larger peace be present Full hidden danger, and drop more allowing blade replacement after rotary cultivator unloads from tractor then workload is larger, back shroud is typically opened into highest Operating personnel's one hand is needed to lift back shroud behind position, or back shroud is lifted in other staff's help, could be below back shroud Safeguard rotary blade, operation inconvenience, operating efficiency is low, general using slotting when back shroud is opened into extreme higher position Pull bar is fixed on the solid seat of pull bar by pin.

R types pin one end of the prior art is draw ring, and the other end is two thin bars, easy to operate during for positioning fixed, But because pull bar is larger by axial force, when load is larger, R types pin easily deforms；The conventional safety pin with anti-decylization It is easy to pull bar circumferential component to interfere；And by the way of R types pin or split pin are fixed using tack finger setting and in the prior art, Operate more complicated, and part is easily lost.The utility model is therefore.

The content of the invention

The utility model purpose is to provide a kind of improved R types pin, and its is simple in construction, easy to operate.

Based on above mentioned problem, technical scheme provided by the utility model is：

Improved R types pin, including insertion section, clamping section and grip part, the clamping section and the grip part are integrated Structure, the insertion section is the column body of rod and external diameter is more than the clamping section, and described grip part one end is fixed on the insertion section One end of axial direction, the other end of the grip part are connected to one end of the clamping section, and the clamping section other end extends to institute The other end of insertion section axial direction is stated, screens is formed between the clamping section and the insertion section outer wall.

In some embodiments wherein, one end of the insertion section axial direction is provided with fixed seat, and the grip part is fixed In the fixed seat.

In some embodiments wherein, the clamping face of screens is curved surface on the clamping section.

In some embodiments wherein, the grip part is cyclic structure.

Compared with prior art, the utility model has the advantages that：

Using the technical solution of the utility model, the insertion sections of the R type pins as location division, clamping section as fixed part, The positioning hole on axostylus axostyle for positioning insertion section insertion needs during use, clamping section is clamped on the outer wall of axostylus axostyle and positioned, inserts Portion is that the column rod member being relatively large in diameter has larger radial direction endurance, avoids occur deforming when axostylus axostyle axial load is larger from asking Topic, and it is easy to use, occupy little space.
