Description

Quick docking mechanism for tractor and agricultural implement

Technical Field

The invention belongs to agricultural machinery, and mainly relates to a quick docking mechanism between a tractor and an agricultural implement.

Background

At present, when an agricultural implement is articulated with a traction power machine, the rear three-point suspension of the traction power machine is generally directly connected with the agricultural implement, the connection operation is labor-consuming and time-consuming, particularly, the phenomenon of shell clamping with inaccurate position is easy to occur, repeated operation is needed, the connection operation efficiency is low, and the labor intensity is high.

Disclosure of Invention

The invention aims to provide a quick butt joint mechanism for a tractor and an agricultural implement aiming at the problems in the prior art, so that the aims of high operation efficiency, labor saving and low operation labor intensity are fulfilled.

The purpose of the invention is realized as follows: the utility model provides a tractor and quick docking mechanism of agricultural implement sets up the locking groove in tractor pull down rod one end inboard the inside suit pressure spring A in tractor pull down rod one end outside, round pin A insert install on tractor pull down rod telescopically and with pressure spring A is the contact cooperation, the center of locking groove is in on round pin A's the centre of turning round, the other end at tractor pull down rod is installed to the arc slide hinge, the hinge center of arc slide sets up T shape spout on round pin A's the centre of turning round, and round pin B inserts on the arc slide telescopically and installs on the arc slide fixed mounting pull rod on round pin B, the pull rod with the T shape spout is the contact cooperation, and pressure spring B suit is in the arc slide, pressure spring B is the contact cooperation with the pull rod, and agricultural implement hangs down the board and inserts to join in marriage inside tractor pull rod, the locking ball penetrates through the lower suspension plate of the agricultural implement and can be freely rotatably mounted in the lower pull rod of the tractor, and the locking ball is in contact fit or contact disengagement fit with the locking groove, the lower suspension plate of the agricultural implement, the arc-shaped slideway, the pin A and the pin B, so that the quick butt joint mechanism of the tractor and the agricultural implement is formed.

The invention realizes the quick butt joint between the tractor and the agricultural implement, and has the characteristics of simple and reasonable structure, accurate and reliable locking, high operation efficiency, labor saving and convenient use.

Description of the part numbers in the figures:

1. the device comprises a pin A, a pin 2, a tractor lower pull rod, a pin 3, an agricultural implement lower suspension plate, a pin 4, a locking ball 5, an arc-shaped slideway, a pin 6, a pull rod 7, a T-shaped chute 8, a pin B, a pin 9, pressure springs A and 10, pressure springs B and 11 and a locking groove.

Detailed Description

The following detailed description of the inventive embodiments is provided in connection with the accompanying drawings. The utility model provides a tractor and quick docking mechanism of agricultural implement, sets up locking groove 11 at tractor lower link 2 one end inboard the tractor is the inside suit pressure spring A9 in the tractor lower link 2 one end outside, round pin A1 insert telescopically install on tractor lower link 2 and with pressure spring A9 is the contact cooperation, the center of locking groove 11 is in on round pin A1's the centre of turning circle line, the other end at tractor lower link 2 is installed to the 5 hinge of arc slide, the center of hinge of arc slide 5 is on round pin A1's centre of turning circle line, sets up T shape spout 7 on arc slide 5, and round pin B8 inserts telescopically and installs on arc slide 5 fixed mounting pull rod 6 on round pin B8, pull rod 6 with T shape spout 7 is the contact cooperation, and pressure spring B10 suits in arc slide 5, pressure spring B10 is the contact cooperation with pull rod 6, the lower suspension plate 3 of the agricultural implement is inserted and assembled inside the lower pull rod 2 of the tractor, the locking ball 4 penetrates through the lower suspension plate 3 of the agricultural implement and is freely rotatably installed inside the lower pull rod 2 of the tractor, and the locking ball 4 is in contact fit or contact disengagement with the locking groove 11, the lower suspension plate 3 of the agricultural implement, the arc-shaped slideway 5, the pin A1 and the pin B8.

During butt joint operation, the arc-shaped slideway 5 is rotated to enable the inlet to be upward, the pull rod 6 is pulled, the pressure spring B10 is compressed, the pin B8 slides in the arc-shaped slideway 5, then the pull rod 6 is rotated to enable the pull rod 6 to slide in the T-shaped sliding groove 7 to the terminal point and then to be kept in a locking state, the tractor slowly backs a car to approach an agricultural implement, when the lower suspension plate 3 of the farm machinery enters the lower pull rod 2 of the tractor, the locking ball 4 is placed in the arc-shaped slideway 5, the hydraulic system on the tractor is utilized to adjust the upper and lower positions of the lower pull rod 2 of the tractor, the front and back positions of the lower pull rod 2 of the tractor are adjusted by the forward and backward movement of the tractor, when the position is adjusted to a proper position, the locking ball 4 automatically rolls into the locking groove 11, the arc slideway 5 and the lower suspension plate 3 of the agricultural implement under the action of gravity, the locking of the pull rod 6 is released, so that the pull rod is in contact fit with the locking ball 4, and the rapid butt joint of the tractor and the agricultural implement is completed; when the butt joint is released, the arc-shaped slideway 5 is rotated to enable the inlet of the arc-shaped slideway to face downwards, the pull rod 6 is locked, the pin A1 is pushed at the moment, the pressure spring A9 is compressed, the pin A1 pushes the locking ball 4 to enable the locking ball to roll out of the arc-shaped slideway 5, and therefore the separation between the tractor and the agricultural implement is completed.
