Abstract

A high-speed transplanting mechanism having a laterally openable/closable duckbill has a duckbill soil penetration angle adjusting arm disposed on a duckbill transplanting portion, the duckbill soil penetration angle adjusting arm has a rear arm and a front arm with each end thereof connected by a reverse-threaded adjusting screw rod, and other ends thereof hingedly connected to an adjusting arm support shaft and the duckbill transplanting portion, respectively. A length of the reverse-threaded adjusting screw rod enables the duckbill to tilt in a direction opposite to a driving direction of a transplanting machine, and a vertical central straight line of the duckbill makes an angle with the ground capable of being adjusted between 65°-85°.

First claim

The invention claimed is:

1. A transplanting mechanism having a laterally openable/closable duckbill, the transplanting mechanism comprising: a power input portion ( 1 ), a driving shaft ( 2 ), a rocker ( 3 ), a connecting rod ( 4 ), a transplanting power arm ( 6 ), a duckbill soil penetration angle adjusting arm ( 5 ), a duckbill transplanting portion ( 9 ), a pot seedling upright device, a mounting base of the transplanting device ( 10 ); wherein the mounting base of the transplanting device ( 10 ) has a power arm support shaft ( 101 ) and an adjustable arm support shaft ( 102 ); a first end of the driving shaft ( 2 ) is connected to the power input portion ( 1 ), a second end of the driving shaft ( 2 ) is fixed at a first end of the rocker ( 3 ), and a second end of rocker ( 3 ) is hinged with a middle of the transplanting power arm ( 6 ), a first end of the transplanting power arm ( 6 ) is hinged with the duckbill transplanting portion ( 9 ), and a second end of the transplanting power arm ( 6 ) is hinged with the power arm supporting shaft ( 101 ); the pot seedling upright device is installed on the duckbill transplanting portion ( 9 ); the duckbill soil penetration angle adjusting arm ( 5 ) has a rear arm ( 52 ) and a front arm ( 54 ) with a first end of the rear arm ( 52 ) and a first end of the front arm ( 54 ) connected by means of a reverse-threaded adjusting screw rod ( 51 ), and a second end of the rear arm ( 52 ) and a second end of the front arm ( 54 ) hingedly connected to the adjustable arm support shaft ( 102 ) and the duckbill transplanting portion ( 9 ) respectively; wherein a length of the reverse-threaded adjusting screw rod ( 51 ) enables the duckbill to tilt in a direction opposite to a driving direction of a transplanting machine, and a vertical central straight line of the duckbill creates an angle with the ground capable of being adjusted between 65°-85°.

2. A transplanting mechanism having a laterally openable/closable duckbill according to claim 1 , wherein the reverse-threaded adjusting screw rod ( 51 ) is adjustable such that a vertical central straight line of the duckbill makes creates an angle with the ground capable of being adjusted between 65°-85°.

3. A transplanting mechanism having a laterally openable/closable duckbill according to claim 1 , wherein each end of the reverse-threaded adjusting screw rod ( 51 ) is equipped with fastening nuts.

4. A transplanting mechanism having a laterally openable/closable duckbill according to claim 1 , wherein an extension part is set at an end of a screw hole of the rear arm ( 52 ) and an extension part is set at an end of a screw hole of the front arm ( 54 ), and wherein the extension parts of the rear arm and the front arm are connected by sliding fit.

5. A transplanting mechanism having a laterally openable/closable duckbill according to claim 4 , wherein a sliding adjusting groove ( 522 ) is provided on the extension part of the rear arm ( 52 ) that is connected to the front arm ( 54 ), a guide pin shaft ( 53 ) is provided on the extension part of the front arm ( 54 ) that is connected to the rear arm ( 52 ), wherein the guide pin shaft ( 53 ) is inserted into the sliding adjusting groove ( 522 ).

6. A transplanting mechanism having a laterally openable/closable duckbill according to claim 4 , wherein the extension part of the front arm ( 54 ) has a counterbore that corresponds to a sectional shape of the extension part of the rear arm ( 52 ), the extension part of the rear arm ( 52 ) is inserted into the counterbore, and wherein two sides of the counterbore guide the sliding fit.

7. A transplanting mechanism having a laterally openable/closable duckbill according to claim 6 , wherein ball bearings are located between the extension part of the rear arm ( 52 ) and the counterbore.

8. A transplanting mechanism having a laterally openable/closable duckbill according to claim 1 , wherein an angle scale plate is set on one side of the duckbill transplanting portion ( 9 ).
