Detailed Description

In order that the inventive concept may be more clearly understood, further details are provided below with reference to the accompanying drawings and specific embodiments.

The celery harvester shown in the figure 1 comprises a travelling mechanism, the travelling mechanism can drive the whole harvester to travel to harvest celery, a harvesting frame 2 is obliquely arranged on the travelling mechanism, a cutting mechanism and a conveying mechanism are arranged on the harvesting frame 2, the cutting mechanism is used for cutting the roots of the celery, the conveying mechanism is used for sequentially conveying the cut celery to the rear of the harvester, the travelling mechanism comprises a frame 1-1 and travelling wheels 1-2, the travelling wheels 1-2 drive the whole harvester to travel through driving of a motor, a storage bin 1-3 and a handrail 1-4 are further arranged on the frame 1-1, the storage bin 1-3 is arranged at the tail of the conveying mechanism, the celery is conveyed into the storage bin through the conveying mechanism to be stored, and the handrail 1-4 is convenient for an operator to hold and master the traveling direction of the harvester.

The front end of the conveying mechanism is close to the side of the harvester as shown in fig. 1, and is basically kept in a line with the travelling wheel on the side where the conveying mechanism is located, but in practice, the width of the travelling wheel can be preferably exceeded, so that the travelling wheel can be prevented from pressing the celery on the adjacent side when the celery is harvested. The vertical tail end level of the whole front end of the conveying mechanism is arranged, so that the middle part is spirally arranged, celery is conveyed from the front end to the tail end process and is gradually toppled to be in a horizontal lodging state, and therefore the celery can be conveniently stacked when falling into the storage bin and is kept neat. The specific conveying mechanism comprises a pair of conveying belts as shown in fig. 1, wherein each conveying belt comprises a driving roller 6-1, a driven roller 6-2 and a belt 6-3, the belt 6-3 is erected between the driving roller 6-1 and the driven roller 6-2, and the celery clamped between the two conveying belts can move in one direction due to the fact that the two conveying belts run in opposite directions, in the embodiment, the two driving rollers 6-1 are in transmission connection through a gear set 6-5, the two driving rollers 6-1 rotate in opposite directions, of course, two motors can be used for driving the two driving rollers 6-1 to rotate in opposite directions respectively, in the embodiment, the gear set 6-5 is used for transmission, so that cost is saved, and the synchronization of the conveying belts can be kept, and the specific conveying mechanism is a preferable technical scheme, one driving roller 6-1 is driven by a conveying motor 6-4, and the conveying motor 6-4 is in transmission connection with one driving roller 6-1 through a chain. In order to realize the dumping of celery in the conveying process, the driving roller 6-1 is horizontally arranged, and the driven roller 6-2 is vertically arranged relative to the driving roller 6-1, so that a belt between the driven roller 6-2 and the driving roller 6-1 forms a spiral shape, the celery is dumped into a horizontal dumping state in the process of moving from the front end to the tail end between two conveyor belts, and is conveniently stacked when falling into the storage bin 1-3. Because the stems of the celery are different in thickness, in order to enable the two conveyor belts to provide proper holding force for the celery, an end plate 8 is arranged on the harvesting frame 2 and used for mounting a driven roller 6-2, a strip-shaped groove is formed in the end plate 8 and can adjust the distance between the two driven rollers 6-2 to adapt to the celery with stems different in thickness, a tail plate 7 for mounting a driving roller 6-1 is further arranged at the tail section of the harvesting frame 2, an arc-shaped hole for mounting one of the driving rollers is formed in the tail plate 7, the distance between the two driving rollers 6-1 is adjusted by adjusting different positions of the arc-shaped hole where the driving roller 6-1 is arranged, namely, one of the driving rollers is fixed, the other driving roller moves along the arc-shaped hole to change the distance between the two belts, meanwhile, the tension of the belts 6-3 can be adjusted by adjusting the positions of the driving rollers 6-1 on the arc-shaped hole, and the tension of the belts can also be achieved by adjusting the distance between the driven roller and the driving roller.

As shown in fig. 2, cutting mechanism includes rotary cutter 3, rotary cutter 3 realizes the cutting to the celery root through the rotation of cutting motor 4 drive, rotary cutter 3 top is provided with protection casing 5, protection casing 5 is the discoid and covers 3 most of rotary cutter, rotary cutter 3 only front end cutting position stretches out protection casing 5 edge, rotary cutter inclines to stretch into the following cutting to the celery root of soil layer during the cutting, and protection casing 5 can effectively block 3 unnecessary positions of rotary cutter and soil contact, reduce the rotatory resistance of soil to the cutter on the one hand, another makes things convenient for the protection cutter to avoid excessive wearing and tearing, general protection casing 5 is fixed not rotatory along with the cutter, of course also can make it rotatory together with the cutter, get rid of surface soil and avoid soil to pile up to one side and hinder the gos forward. Be provided with the supporting wheel 11 that can height-adjusting near cutting mechanism one end at results frame 2, adjust the degree of depth that rotary cutter 3 stretched into the soil layer through the height of adjusting supporting wheel 11, supporting wheel 11 is the universal wheel, makes things convenient for the harvester to turn to the operation when the road surface is gone.

Because the harvester moves forwards when the rotary cutter 3 cuts celery, in order to avoid the situation that the celery cannot be clamped and conveyed by the conveyor belt because the celery is pushed down without entering the conveyor belt, the front end of the harvesting frame 2 is provided with a pair of reel disks 9 which are respectively linked with the driven rollers 6-2, the driven rollers 6-2 drive the reel disks 9 to synchronously rotate through chains, a group of reel claws 9-1 are arranged on the periphery of the reel disks 9, the celery is pulled up to the direction of the conveyor belt in a forward moving process, and then the celery can smoothly enter the conveyor belt for conveying after the cutting is finished. In order to facilitate installation and position adjustment of the driven rollers 6-2 and the reel 9, as shown in fig. 3, a movable frame 10 is installed on an end plate 8, the movable frame 10 is installed on the end plate 8 through a strip-shaped groove, a strip-shaped hole is also formed in the movable frame 10, the strip-shaped hole is perpendicular to the strip-shaped groove, so that the distance between the two movable frames 10 can be adjusted to adjust the distance between the two driven rollers 6-2, meanwhile, each driven roller 6-2 can move along the length direction of the conveyor belt to adjust the tension of the belt, a strip-shaped groove for installing the reel 9 is further formed in the movable frame 10, and each reel 9 can transversely move on each movable frame 10 to adjust the distance between the two driven rollers 6-2.
