In this embodiment, as shown in Figure 6, control system comprises: single-chip microcomputer 10, display 20, relay 30, first magnetic valve 40, second magnetic valve 50, voltage comparator 60 and amplifier 70; Inductor 25, amplifier 70, voltage comparator 60 and single-chip microcomputer 10 connect successively, single-chip microcomputer 10, relay 30, second magnetic valve 50 and auxiliary induction device connect (more specifically successively, single-chip microcomputer 10, relay 30, second magnetic valve 50 and hydraulic cylinder 41 connect successively, and some second foil gauges 43 are connected with amplifier 70 respectively), relay 30, first magnetic valve 40 and cutter sweep 5 (the hydraulic cylinder cutoff tool 51 namely in cutter sweep 5) connect successively, and display 20 is connected with single-chip microcomputer 10.
, introduce the anti-principle of hindering bud system of sugarcane kind cutting in this embodiment in detail below, specific as follows:
Sugarcane 1 enters from the typhon end of rubber sleeve 2 (all can produce deformation with foil gauge for making sugarcane 1, if the diameter of rubber sleeve 2 toy trumpet end is slightly less than the average diameter of sugar cane stem), when arriving the toy trumpet end of rubber sleeve 2, the kind bud (being the position of projection relative to sugarcane genotypes) of sugarcane 1 extrudes the first foil gauge 25, produce deflection, utilize resistance strain effect, its deflection is converted to electric signal transmission to amplifier, because the first foil gauge 25 has sensed sugarcane kind bud, single-chip microcomputer makes hydraulic cylinder 41 be shunk by second foil gauge 43 by Control second magnetic valve, induction is repeated to avoid the second foil gauge 43, at this moment, the signal of telecommunication is transferred to single-chip microcomputer counting 1 through comparator, and count results shows by display, sugarcane continues to transmit, when second kind bud is through the first foil gauge 25, single-chip microcomputer 10 counts 2, and carry out segment by Control first solenoid-driven hydraulic cutting breaking 51 pairs of sugar cane stems, to obtain the sugar cane stem (required by agronomic technique) with two kind buds, single-chip microcomputer 10 counts and resets simultaneously, automatically enter next counting to circulate with cutting.
If run into the larger sugarcane of Trunk diameter 1, after sugarcane 1 enters rubber sleeve, two and half tubaeform rubber sleeves 21 of rubber sleeve 2, 22 is softened, when being positioned at two and half tubaeform rubber sleeves 21, first foil gauge 25 of 22 can respond to sugarcane kind bud, do not affect above-mentioned steps, the kind bud can working as sugarcane 1 just in time passes through from softened non-inductive district, when first foil gauge 25 cannot be responded to (the first foil gauge no signal exports), second foil gauge 43 does not shrink, at this moment, sugarcane kind bud is when the second foil gauge 43, the second foil gauge 43 will be made to produce deformation and to produce the signal of telecommunication, count, during full 2 of counting, Single-chip Controlling hydraulic cutting breaking 51 cuts off sugarcane, same acquisition has the sugar cane stem of two kind buds, this design not only can prevent rubber sleeve to be bursting at the collision, and can prevent the phenomenon of counting loss from occurring.
As shown in Figure 1, in this embodiment, supporting seat comprises two U-shaped support columns 52, forms dual-gripper cutting; and hydraulic cylinder cutoff tool 51 is positioned at directly over two U-shaped support columns 52; as preferably, U-shaped support column 52 is all equipped with flexible rubber lagging, can plays a protective role to kind of a bud.
As shown in Figure 3 and Figure 4, the all sticky note in interior outside of some first foil gauges 25 and some second foil gauges 43 has elastomeric material, and there is the thickness that one is suitable, can ensureing that foil gauge can sense the signal of highly less kind bud, the load of the foil gauge when detecting higher sugarcane bud being alleviated again.Foil gauge in this embodiment is resistance strain plate, and existing resistance strain plate is generally rectangular, pastes, the side of elastomeric material is made regular prism shape, so form sensing part for convenience of it.
As shown in Figure 5, record through the present inventor's experiment, distance between inductor 25 and hydraulic cylinder cutoff tool 51 is set as and is greater than one times of sugarcane interval and is less than twice sugarcane interval, with guarantee counting reach requirement after cutting knife avoid kind of a bud completely, thus realize the cutting of sugarcane kind and anti-ly hinder tooth function.Its specific experiment is as follows:
Randomly draw 500 sugarcane interval samples, recording its maximum interval is 104mm, and minimum interval is 86mm.As shown in Figure 5, contain two bud according to agriculture requirement every section sugarcane kind need, then the length S of every section of sugarcane kind should be greater than one times of interval and be less than three times of intervals, then the length of every section of sugarcane kind under two kinds of limiting case is:
86mm<S
min<258mm
104mm<S
max<312mm (1)
Two limiting cases are sought common ground, then can obtain:
104mm<S<258mm (2)
When kind of a bud counting just reaches 2, namely second kind bud is through inductor, need to send control signal control cutoff tool immediately and cut sugarcane kind, now, kind of a bud is avoided to make cutoff tool, then need to meet: inductor should be greater than one times of interval to the distance L of cutoff tool and be less than twice interval, according to the sugarcane interval recorded, same consideration two kinds of limiting cases obtain:
86mm<L
min<172mm
104mm<L
max<208mm (3)
Seek common ground equally:
104mm<L<172mm (4)
Namely, when the distance of inductor and cutting knife is within the scope of 104-172mm, can realize anti-ly hindering tooth function.
In this embodiment, the operation principle of resistance strain plate is resistance strain effect, and namely wire is when forces are applied, and its resistance, along with the size of occurred mechanically deform, corresponding change occurs.Because the output signal of resistance strain plate is general very faint, fan-out capability is little, needs to carry out necessary amplification to it, to adapt to the further processing requirements such as display, conversion, transmission.For eliminating the temperature error of resistance strain plate and improving its sensitivity, often resistance strain plate is connected into Wheatstone bridge.
The aforementioned description to concrete exemplary of the present invention is to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present invention and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present invention and various different selection and change.Scope of the present invention is intended to limited by claims and equivalents thereof.
