Detailed Description
Example one
The combined leaf-cutting mechanism for vegetable heads of this embodiment is shown in fig. 1, and will be described in detail below starting with the structure of a self-propelled combined vegetable head harvester using this mechanism. In fig. 2, 3 and 4: 1. an automatic dial-leading device; 2. a disc root cutting device; 3. a frame; 4. a traveling device; 5. a control system; 6. an impurity removal device; 7. a conveying and lifting device; 8. a second-stage leaf shearing device; 9. a first-stage leaf-cutting device; 10. a blade-arranging spiral roller; 11. a rotating blade paddle wheel. The front part of a frame 3 arranged on a walking device 4 is provided with a conveying lifting device 7, the conveying lifting device 7 consists of a front conveying flat plate 2-7 and a rear chain type lifting machine, chain links of the chain type lifting machine are provided with bucket type mechanisms at intervals, the bucket type mechanisms have more specific structures comprising arc hook digging teeth 7-1 at the lower end and arc plates 7-2 at the upper end, and the arc hook digging teeth 7-1 and the arc plates 7-2 are fixedly connected through groove type straight plates 7-3. This bucket formula mechanism can effectively play and prevent that the green vegetable head from rolling down in the lifting transportation to the back upper place, avoids it to pile up the jam, and the curved hook digs the tooth and still plays the effect of initiative album dish simultaneously.
The middle part of the transmission flat plate 2-7 supports a pair of vertical cutter shafts 2-3 which are respectively driven by a driving motor 2-4 through a transmission belt, and the lower ends of the cutter shafts 2-3 are provided with disk cutters 2-2 (see figure 7) to form a disk root cutting device 2. The two paired disk cutters 2-2 are staggered up and down to form a certain overlapping area, so that the phenomenon that the core part is not cut or is not cut continuously in the cutting process is effectively avoided. The soil pressing plate 2-1 is arranged below the disc cutter 2-2, so that the soil pressing plate can flatten the ground with poor flatness and prevent the disc cutter from cutting soil and hilling, and the front end of the soil pressing plate 2-1 is bent upwards, so that the trafficability of the soil pressing plate can be improved. An intermittent rotary cylinder 2-5 is sleeved outside a vertical cutter shaft 2-3 in an empty manner, an extension end of an active shifting fork 2-6 which can contact the intermittent rotary cylinder 2-5 is arranged on the outer side of a transmission belt, so that when the active shifting fork moves to the intermittent rotary cylinder along with the belt, the rotary cylinder can be shifted to rotate to enable the rotary cylinder to rotate intermittently, and the effect of the intermittent rotary shifting fork is to prevent a cut vegetable head from being accumulated on a transmission flat plate after the rotary shifting roller and a disc cutter lose backward transmission power, so that congestion, crushing or falling are caused.
The front end of the transmission flat plate 2-7 is fixedly provided with a mounting bracket with the lower part provided with a horizontal fixed rail 1-5, the position of the horizontal fixed rail 1-5 corresponding to the main leading and dialing roller 1-6 is provided with a horizontal slide rail 1-4 which forms a lockable horizontal moving pair with the horizontal fixed rail, the horizontal slide rail 1-4 supports the main leading and dialing roller 1-6 which drives the outward rotation of the leading and dialing motor 1-7 through the leading and dialing frame 1-3 fixedly connected with the horizontal slide rail, and the horizontal slide rail has the functions of righting the lodged vegetable head and gathering scattered leaves so as to facilitate the subsequent leaf and root cutting operation; the distance between the paired main drawing and poking rollers can be adjusted according to the size of the vegetable heads, so that the vegetable can not be blocked due to overlarge size or can not be righted due to undersize size. The front end of the main leading and shifting roller 1-6 is hinged with a conical head leading and shifting roller 1-1 with the inner side limited and the outer side propped against the pressure spring, when a green vegetable head with poor planting straightness is harvested, the conical head leading and shifting roller can automatically adjust the size of the opening at the front end around a hinge fulcrum at the rear end, and feeding of the green vegetable head is guaranteed.
As shown in fig. 1 and referring to fig. 5 and 6, a first-stage leaf-cutting rotary knife 9 supported below a side row mounting rack 8-6 is respectively arranged above two pairs of main drawing and poking rollers 1-6, a leaf-row spiral roller 10 is arranged on the side row mounting rack 8-6, and a rotary leaf poking wheel 11 is arranged above the front of the leaf-row spiral roller 10. The first-stage leaf-cutting rotary knives 9 are straight-line-shaped blades, the blades are cut off by the horizontal circular rotation motion, the first-stage leaf-cutting rotary knives 9 on the two sides are staggered up and down and have a certain overlapping area, the effect is that most of the blades above the vegetable stems are cut off firstly, and a large number of cut blades are collected to the leaf-discharging spiral roller under the action of the rotary thumb wheel and are discharged from one side along with the rotation of the roller.
As shown in fig. 4 and 5, a fixed vertical rail 8-4 is arranged at the rear side of the side row mounting rack 8-6, the fixed vertical rail 8-4 and the rear mounting rack 8-3 form a vertical moving pair, two ends of a cross rod 8-7 fixedly connected with the rear mounting rack 8-3 are respectively hinged with the upper ends of the connecting rods 8-5, the lower ends of the two connecting rods 8-5 are adjacent and respectively hinged with the corresponding guiding and pulling rack 1-3, and a second-stage leaf-cutting rotary cutter 8-1 positioned at the middle rear part of the two first-stage leaf-cutting rotary cutters is arranged at the lower end of the rear mounting rack 8-3; when the vegetable stem is too large, the poking device expands outwards under the action of a horizontal moving side effect, the lower end of the connecting rod 8-5 stretches outwards, and as a result, the cross rod moves upwards under the restraint of the vertical moving pair, and the position of the joint of the head stem and the leaves of the large vegetable stem is correspondingly higher, so that the cross rod drives the rear mounting rack 8-3 to rise, and the cutting height is precisely controlled.
Considering that the leaves of the green vegetable heads are more and longer, the two-stage leaf cutting device is arranged in the embodiment, the leaf cutting rotary knife 8-1 is directly connected with the driving motor, and along with the forward movement of the harvester, the green vegetable heads which are subjected to leaf cutting move backwards relatively, and the stem and leaf joint is accurately cut by the two-stage leaf cutting rotary knife 8-1, so that the leaves are completely removed.
The frame 3 of the embodiment is provided with an impurity removing device 6 below the output end of the conveying and lifting device 7. The impurity removing device is composed of a pair of large-diameter spiral rolling brushes and two pairs of small-diameter hair rolling brushes, the contact parts of the rolling brushes and the vegetable heads are made of soft materials, residual soil and vegetable leaves on the vegetable heads can be removed, vegetables are not damaged, and the spiral rolling brushes also play a role in conveying the vegetable heads to the rear.
Experiments prove that the primary leaf cutting device comprising the leaf cutting knife, the impeller, the spiral conveying roller and the like can cut most of leaves of the head of the green vegetables and return the leaves to the field in a side row; and the second-stage leaf-cutting device is provided with a height follow-up adjusting mechanism, so that the combined position of the nodular stem and the leaves can be profiled, and the stem and the leaves can be accurately cut and separated. Compared with the traditional mechanical harvesting which needs manual secondary leaf removal, the reasonable design organically combining the two-stage leaf cutting not only greatly improves the efficiency, but also obviously reduces the harvest impurity rate and ensures the harvest quality because the stem leaf combining position is accurately cut and is matched with the root cutting mechanism.
