[specific embodiment]
Fig. 1 to Fig. 6 is please referred to, in a kind of better embodiment of the invention, a kind of overlay film agricultural machinery that plows automatically, including
One walking mechanism 1, a ploughing apparatus 2 and a film covering device 3, ploughing apparatus 2 is mounted on 1 bottom of walking mechanism, and fills in overlay film
3 fronts are set, film covering device 3 is connected to 1 rear portion of walking mechanism, is drawn and is advanced by walking mechanism 1 with ploughing apparatus 2.
Wherein, referring to Fig. 2, ploughing apparatus 2 includes a several colters 21, one plough axis 22 and actuator 23, between colter 21
Every being mounted on plough 22 lateral surface of axis, and along the axial setting of plough axis 22, and its blade is away from plough axis 22;The connection plough of actuator 23
Axis 22 can drive colter 21 to rotate by driving plough axis 22.Preferably, colter 21 is at sickle shaped.
Fig. 3 to Fig. 6 is please referred to, film covering device 3 includes that first hydraulic cylinder 31, a main frame 32, a controller and pressure pass
Sensor.First hydraulic cylinder 31 connects controller, and one end is mounted in walking mechanism 1, other end rotation connection main frame 32.It is main
Frame 32 is rotatably mounted in walking mechanism 1, which is provided with an overlay film bar 33, and a film roll 331 is set on overlay film bar 33, thin
331 both ends of film roll are mounted on a stamper support 35 and a ridging bracket 34;A pressing wheel is rotatably equipped on stamper support 35
351, pressing wheel 351 is located at the inside of 331 end of film roll, and a ridging wheel 341, ridging wheel are rotatably equipped on bracket 34 of earthing up
341 are located at the outside of 331 end of film roll, and the diameter for wheel 341 of earthing up is greater than the diameter of pressing wheel 351;It is covered in film covering device 3
Membrane process, pressing wheel 351 and ridging wheel 341 all fall within the rear of film roll 331, and the bottom of the two is also located at film roll
331 lower sections.Pressure sensor is mounted on stamper support 35, and is located at the part that stamper support 35 contacts pressing wheel 351, is used for
The pressure that is subject to of detection pressing wheel 351, and generate corresponding inductive signal and be sent to the controller being attached thereto, controller root again
Run according to inductive signal driving first hydraulic cylinder 31, with by the telescopic action of first hydraulic cylinder 31 drive main frame 32 around
Main frame 32 is rotated with the rotation junction of walking mechanism 1 relative to walking mechanism 1.
Agricultural machinery designed by the present invention, which has both, to plow and film covering function, wherein ploughing apparatus 2 is for plowing, and preferably it is ploughed
The axis of axis 22 is parallel to the axis of 3 film roll 331 of film covering device;The main frame 32 and walking mechanism 1 of film covering device 3 are rotations
Connection, which opposite walking mechanism 1 can spin upside down under the driving of first hydraulic cylinder 31, and first hydraulic cylinder
31 operation can be controlled by controller, so that the flip angle of main frame 32 is automatically controlled, can avoid main frame occur
Frame 32 is because rotating the possibility excessively damaged, wherein controller is to carry out instruction control by the inductive signal of pressure sensor
, control principle is to experience pressing wheel 351 by the pressure sensor at pressing wheel 351 and stamper support 35 because of it contiguously
Face and to sub- membrane support bring pressure, whether controller continues to run or stops further according to pressure control first hydraulic cylinder 31
It only runs, that is, when controller receives the inductive signal that pressure sensor transmits, controller, which controls first hydraulic cylinder 31, to be stopped
Operation, at this point, pressing wheel 351 is gently compressed on film, and wheel 341 of earthing up gos deep into soil, and therefore, which can make pressing wheel
351 are compressed on film, while 351 rolling process of pressing wheel being avoided to cut bad film.And in order to make two pressing wheels 351 can be with
Film contacts are mounted on pressure sensor on two stamper supports 35 of film covering device 3, and pressure sensor is located at stamper support
The bottom of the part of 35 contact pressing wheels 351, so that pressure sensor preferably incudes 351 bring pressure of pressing wheel.In addition,
For the overturning for keeping main frame 32 stable, film covering device 3 is provided with two first hydraulic cylinders 31, which sets up separately
32 two sides of main frame.
Further, the stamper support 35 of film covering device 3 and ridging bracket 34 are slidably mounted on main frame 32, and two
Person is all connected with the second hydraulic cylinder 36 being arranged on main frame 32, and towards far from film roll under the action of second hydraulic cylinder 36
331 middle parts are slided close to the direction at 331 middle part of film roll with respect to main frame 32, and the route of the two sliding is parallel to film roll
331 axis directions, to realize the cross of film covering device 3 with respect to the sliding of main frame 32 by stamper support 35 and ridging bracket 34
To adjustment, to enable the ridging wheel 341 on the pressing wheel 351 and ridging bracket 34 on stamper support 35 according to film roll
The lateral distance of the opposite film roll 331 of both 331 length (i.e. the width of film) adjustment makes the overlay film agricultural machinery that plows automatically
In coating process, pressing wheel 351 can be located on film, and wheel 341 of earthing up is located at film outside.Preferably, on main frame 32
Two second hydraulic cylinders 36 are provided with, each second hydraulic cylinder 36 is connect with the stamper support 35 of the same side, ridging bracket 34, and
Stamper support 35 and ridging bracket 34 can be driven to slide with respect to film roll 331, and then realize stamper support 35 and ridging bracket
34 adjust automatically, while stamper support 35 and ridging bracket 34 are fixed.
Further, in the present invention, the bottom of pressing wheel 351 is located at the top of 341 bottoms of ridging wheel, that is, makes press mold
The diameter of wheel 351 is less than the diameter of ridging wheel 341, thus make pressing wheel 351 in light press membrane, the deeply soil of wheel 341 of earthing up
It is interior, and then convenient for soil is covered on film both ends, while pressing wheel 351 will not cut bad film;Pressing wheel 351 and ridging wheel 341
It is arranged in parallel, and is vertically arranged with film roll 331, and pressing wheel 351 is mounted on stamper support 35 by a connecting rod 352,
