5) when the crank 301 drives the transverse support 308, the pressure head 309 and the pressure lever 310 to move to the bottom dead center position, soil in the soil collector 401 is compressed into a pot body, the left cam 315 triggers the left electromagnetic switch 314 to be closed, the lower electromagnetic valve 404 is electrified to drive the lower baffle 403 to move outwards, the channel at the lower part of the soil collector 401 is opened, and the pot body is pushed out of the soil collector 401;

6) then the crank 301 drives the transverse support 308, the pressure head 309 and the pressure rod 310 to move upwards, when the pressure head 309 moves to a position higher than the upper end of the soil collector 401, the intermittent mechanism 500 drives the soil collector 401 to rotate 120 degrees, and one working cycle is completed;

2) in the punching mechanism (300), a crank shaft (313) drives a transverse support (308) to reciprocate up and down through a crank (301) and a connecting rod (306), and a pressure rod (310) and a pressure head (309) compress and mold soil in a soil collector (401);

3) the motor (900) drives the incomplete driving gear (501) of the intermittent mechanism (500) to do continuous rotary motion, and when the smooth round surface of the incomplete driving gear (501) is contacted with the notch of the incomplete driven gear (504), the incomplete driven gear (504) is static; when the blocking strip (502) is contacted with the stop block (503), the incomplete driving gear (501) is meshed with the incomplete driven gear (504), and the blocking strip (502) is separated from the stop block (503); the incomplete driving gear (501) and the incomplete driven gear (504) are meshed, and one circulation motion is finished;

4) when the soil collector (401) rotates to a position corresponding to a discharge hole in the stirring box (201), the right cam (303) triggers the right electromagnetic switch (304) to be closed, the upper electromagnetic valve (206) is electrified to drive the upper baffle (205) to move, a discharge hole channel is opened, and soil in the stirring box (201) is conveyed into the soil collector (401) under the action of the scraper (202);

5) when the crank (301) drives the transverse bracket (308), the pressure head (309) and the pressure rod (310) to move to the position of the lower dead center, soil in the soil collector (401) is compressed into a pot body; a left cam (315) triggers a left electromagnetic switch (314) to be closed, a lower electromagnetic valve (404) is electrified to drive a lower baffle (403) to move outwards, a channel at the lower part of the soil collector (401) is opened, and the pot body is pushed out of the soil collector (401);

6) and (5) repeating the steps 2) -4) to reciprocate up and down to realize twice compaction and twice ejection.
