Embodiment 2

Fig. 8 is please referred to, present embodiments provides a kind of lotus root -digging out method, uses above-mentioned lotus root digging harvester 100, lotus root digging harvester 100 Structure can be with reference implementation example 1.

The lotus root -digging out method includes：

Lotus root digging harvester 100 is put into rectangular lotus field, second sensor 14 and 3rd sensor 15 is made to contact ridge, control Device 23 receives the transducing signal of sensory package and is recorded as the initial position of lotus root digging harvester 100；

Control device 23 controls driving motor 21 and pump 22 is made to work, and the water spray of nozzle 17 is made to carry out lotus root-digging out operation, control dress It puts 23 control, three steering motors and makes the water spraying direction of three jetting members consistent, floating drum 11 is made to move ahead along the first preset direction, First preset direction is perpendicular to the line direction of second sensor 14 and 3rd sensor 15；

When first sensor 13 contacts ridge, control device 23 controls three steering motors and makes three jetting members opposite It is rotated in rack 12, makes floating drum 11 relative to 90 ° of lotus field rotation clockwise, control device 23 controls three steering motors and makes three A jetting member resets, and floating drum 11 is made to move ahead a default station along the second preset direction, the second preset direction with first it is default just To being vertically arranged；

Control device 23 controls three steering motors and three jetting members is made to be rotated relative to rack 12, makes floating drum 11 opposite In 90 ° of lotus field rotation clockwise, control device 23 controls three steering motors and resets three jetting members, makes floating drum 11 along the Three preset directions move ahead, and third preset direction is opposite with the first preset direction；

When first sensor 13 contacts ridge, control device 23 controls three steering motors and makes three jetting members opposite It is rotated in rack 12, makes floating drum 11 relative to 90 ° of lotus field rotation counterclockwise, control device 23 controls three steering motors and makes three A jetting member resets, and floating drum 11 is made to move ahead a default station along the second preset direction；

Control device 23 controls three steering motors and three jetting members is made to be rotated relative to rack 12, makes floating drum 11 opposite In 90 ° of lotus field rotation counterclockwise, control device 23 controls three steering motors and resets three jetting members, makes floating drum 11 along the One preset direction moves ahead；

When first sensor 13 contacts ridge, control device 23 controls three steering motors and makes three jetting members opposite It is rotated in rack 12, makes floating drum 11 relative to 90 ° of lotus field rotation clockwise, control device 23 controls three steering motors and makes three A jetting member resets, and floating drum 11 is made to move ahead along the second preset direction, and current line is not to a default station, the first sensing at this time Device 13 contacts ridge, and control device 23 receives the transducing signal of sensory package and is recorded as the final position of lotus root digging harvester 100.

It is described with the relative position in Fig. 8, generally, lotus field selects rectangular lotus field, lotus root digging harvester 100 is from a left side for lotus field Lower section proceeds by lotus root-digging out operation, and first sensor 13 is located at the top of floating drum 11 at this time, and second sensor 14 is located at floating drum 11 Left side, 3rd sensor 15 is located at the right side of floating drum 11.

Under initial position, the 16 relatively close ridge of service pipe, second sensor 14 and 3rd sensor 15 contact field Close to ridge, the process of operation is for the ridge or the limit：

Floating drum 11 moves upwards under the action of three jetting members, and nozzle 17 sprays water with high pressure the region inswept to floating drum 11 Lotus root-digging out operation is carried out, when first sensor 13 touches ridge, control device 23 receives the signal, and control steering motor is driven Dynamic three jetting members rotation, makes its 90 ° of rotation clockwise, which can be derived from the average time turned by many experiments and be It is accurate, that is to say, that under the average time, generally, 90 ° of the 11 similar rotation of floating drum.

At this point, steering motor drives three jetting members, make its reset, the vertex where first sensor 13 is as forward Endpoint makes its default station that moves ahead, and similarly, this default station can also be taken subject to the average time by many experiments, That is under the average time, the length of itself of the floating drum 11 generally, floating drum 11 has almost moved ahead.

At this point, control device 23 controls steering motor, make 11 90 ° of rotation clockwise of floating drum so that 14 He of second sensor 3rd sensor 15 contacts ridge or the limit close to ridge, and then jetting member reset, under the action of pump 22, floating drum 11 is transported downwards It is dynamic, after first sensor 13 contacts ridge, 11 90 ° of rotation counterclockwise of floating drum, then with the vertex where first sensor 13 As forward endpoint, make its 90 ° of rotation counterclockwise after making its default station that moves ahead, then with where first sensor 13 Vertex as forward endpoint, it is made to move ahead.

Above-mentioned operation is repeated, until when floating drum 11 needs the default station that moves ahead, and it is practical not to a default work Position, in the case which just contacts ridge, control device 23 records the position as final position at this time, to scheme Position in 8 is described, and final position is located at the upper right side of ridge at this time.

In this way, no matter lotus field area have it is much, after reciprocation cycle operation, total energy realize floating drum 11 move ahead During one default station, first sensor 13 contacts ridge, and lotus root digging harvester 100 has carried out entire lotus field completely at this time Lotus root-digging out operation.

In conclusion the utility model provides a kind of lotus root digging harvester 100, which can dig lotus root automatically, drop significantly Low artificial intensity, while greatly reduce and dig lotus root cost, it is planted suitable for large-scale lotus field.The lotus root digging harvester 100 design is closed Reason, market application potential are huge.

The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
