Abstract

This present invention provides an automatic pot seedlings feeding mechanism for semi-automatic transplanter, comprising a transmission mechanism, a slider-crank mechanism, a stop lever, a side plate, a resetting mechanism and a bearing with bearing support. The transmission mechanism includes a transmission shaft I, a driving wheel, a transmission shaft II, a transmission shaft III and a conveyor belt. Under the performance of the conveyor belt, the pot seedlings are transported forward to the position of the stop lever. The slider-crank mechanism comprises a crank, a slider bar and a sliding chute, the crank and the driving wheel are connected through a revolute pair A, which is on the driving wheel, but not at the center of the driving wheel. The slider is securely connected with the resetting mechanism.

First claim

We claim:

1. An automatic pot seedlings feeding mechanism for a semi-automatic transplanter, comprises:
a transmission mechanism,
a slider-crank mechanism,
a stop lever,
side plates,
a resetting mechanism-and
bearing supports which contains bearings;
wherein the transmission mechanism of the feeding mechanism includes a transmission shaft I, a driving wheel, a transmission shaft II and a transmission shaft III;
wherein the transmission shaft I and the driving wheel form a fourth revolute pair, the transmission shaft II and the conveyor belt form a fifth revolute pair, the transmission shaft III and the conveyor belt form a sixth revolute pair;
wherein the slider-crank mechanism comprises a crank, a slider bar and a sliding chute, the crank and the driving wheel are linked through a first revolute pair, the first revolute pair is on the driving wheel, but not at the center of the driving wheel; and
wherein the slider bar and the crank are linked through a second revolute pair, the sliding chute and the slider bar are linked by the a prismatic pair, the stop lever and the resetting mechanism are connected by a third revolute pair, the connection of the resetting mechanism and the slider bar are connected by a hinge joint.

2. An automatic pot seedlings feeding mechanism for the semi-automatic transplanter according to claim 1 , wherein when the slider-crank mechanism moves right to a first point of a limit position, the stop lever will rotate around third revolute pair by the action of the sides plate and the resetting mechanism, and the stop lever will move from an original state to a leading end position of the notch of the sides plate; when the slider-crank mechanism moves left to a second point of a limit position, the stop lever will get back to the original state under the action of the sides plate and the resetting mechanism.

3. An automatic pot seedlings feeding mechanism for the semi-automatic transplanter according to claim 1 , wherein the resetting mechanism is composed of a small controllable motor and the cylindrical shell; the motor operably connected to drive the stop lever to wherein the motion of the stop lever is configured to prevent successive feeding of the next pot seedling, the cylindrical shell of the resetting mechanism and one end of the slider bar are connected by the hinge joint.

4. An automatic pot seedlings feeding mechanism for the semi-automatic transplanter according to claim 3 , wherein when the stop lever is pivoted to the limit position on the side plate, the motor just rotates one or more pulses and controls the conveyor belt to feed a predetermined distance.

5. An automatic pot seedlings feeding mechanism for the semi-automatic transplanter according to claim 1 , wherein the side plates can be bended into a trumpet shape so that the operator will easily send the pot seedlings into the conveyor belt of the transmission mechanism.

6. An automatic pot seedlings feeding mechanism for the semi-automatic transplanter according to claim 1 , wherein the automatic pot seedlings feeding mechanism for the semi-automatic transplanter can be used directly for one row transplanter, or the semi-automatic transplanter can also be used in juxtaposition and in combination with two or more semi-automatic transplanters so as to realize the multi-line automatic feeding of seedlings and transplanting.
