Abstract
Description
Technical fields:
[0001] This utility model relates to the field of gourd machine technology, and in particular to a gourd machine cutting platform grass removal device. Background technology:
[0002] Currently, gourd harvesters are mainly used for harvesting seeds of gourds, watermelons, and seed gourds. For example, patent application CN220799132U discloses a cutting platform mechanism for a watermelon harvester. The cutting platform is equipped with a vine-cutting component, a gourd-picking component, a vine-pulling component, a gourd-removing device, and a cutting platform conveyor belt. During operation, the vine-cutting component initially separates the gourds from the vines and grasses. The gourds are picked up by the gourd-picking teeth on the vine-picking component and removed by the gourd-removing device during rotation. The fallen gourds roll into the collection bin at the rear. Some of the vines and grasses remaining on the gourd-removing device are pushed forward by the vine-pulling component to the cutting platform conveyor belt and discharged to one side by the cutting platform conveyor belt. The cutting platform conveyor belt has a horizontal structure, which has the following disadvantages during use: First, the weed-removing teeth cannot be designed to be too long. If they are too long, the entire conveyor belt needs to be raised to allow space for the weed-removing teeth to rotate. Raising the conveyor belt and adding the height of the seedlings can easily obstruct the view of the hoist operator's cab. If the weed-removing teeth are not long enough, the weed removal speed will be slow, the efficiency will be low, and the seedlings will easily accumulate and become tangled. Second, there is no obstruction at the front of the conveyor belt. During the weed removal process, the seedlings on the conveyor belt can easily fall forward onto the protective cover of the seedling trimming component, causing the seedlings to accumulate and requiring frequent cleaning, which increases the workload. There is currently no good solution to these problems.
[0003] In summary, the problem of weed removal from the cutter table of the hoist has become a technical challenge that urgently needs to be solved in the industry. Utility Model Content:
[0004] To overcome the shortcomings of the prior art, this utility model provides a grass removal device for a gourd machine cutter, which solves the problems of slow grass removal speed, low efficiency, and easy falling of grass to the front side by the previous horizontal conveyor belt.
[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:
[0006] A gourd harvester cutting platform weed removal device includes a frame, on which a seedling cutting component, a gourd picking component, a gourd remover, and a seedling pulling component are mounted. A vertical conveying mechanism is mounted on the frame in front of the seedling pulling component. An inclined front frame slide is mounted on the frame between the vertical conveying mechanism and the seedling pulling component. The vertical conveying mechanism includes a conveyor belt main frame mounted perpendicular to the front frame slide. A drive shaft and a driven shaft are respectively mounted on both sides of the conveyor belt main frame. A vertical annular conveyor belt is sleeved on the outside of the drive shaft and the driven shaft. Several weed-pulling tooth plates are installed at intervals on both sides of the vertical annular conveyor belt, and several weed-pulling teeth are installed on each weed-pulling tooth plate.
[0007] Reinforcing support rods are installed on both sides of the top of the conveyor belt main frame and between it and the machine frame.
[0008] The bottom of the vertical circular conveyor belt makes sliding contact with the front frame slide.
[0009] Several nylon belt rollers are installed on the bottom side of the frame corresponding to the vertical annular conveyor belt away from the front frame slide.
[0010] The grass-removing teeth are connected to the grass-removing tooth plate by detachable screws.
[0011] The present invention adopts the above solution and has the following advantages:
[0012] By installing a vertical conveyor mechanism on the frame at the front of the seedling removal assembly, and installing several weed-removing teeth on both sides of the vertical circular conveyor belt, the space reserved for the weed-removing teeth to rotate in the front and rear positions of the cutter can be fully utilized. There is no need to raise the height of the entire conveyor belt, thus avoiding obstructing the view of the hoist operator's cab. Moreover, the weed-removing teeth are long enough to remove weeds quickly and efficiently, preventing seedlings from piling up and tangling. In addition, the vertical circular conveyor belt can also block the seedlings, effectively preventing them from falling forward onto the protective cover of the seedling removal assembly, thus achieving the effect of smoothly removing the seedlings to one side of the hoist cutter. Attached image description:
[0013] Figure 1 This is a schematic diagram of the structure of this utility model.
[0014] Figure 2 This is an enlarged structural schematic diagram of the vertical conveying mechanism of this utility model.
[0015] In the diagram, 1 is the frame, 2 is the seedling removal assembly, 3 is the melon picking assembly, 4 is the melon remover, 5 is the seedling pulling assembly, 6 is the vertical conveyor mechanism, 7 is the front frame slide, 8 is the main conveyor belt frame, 9 is the drive shaft, 10 is the driven shaft, 11 is the vertical circular conveyor belt, 12 is the weeding tooth plate, 13 is the weeding tooth, 14 is the reinforcing support rod, and 15 is the nylon pressure roller. Detailed implementation method:
[0016] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.
[0017] like Figure 1-2 As shown, a gourd harvester cutting platform weed removal device includes a frame 1. A seedling-cutting assembly 2, a gourd-picking assembly 3, a gourd-removing device 4, and a seedling-pulling assembly 5 are mounted on the frame 1. A vertical conveyor mechanism 6 is mounted on the frame 1 in front of the seedling-pulling assembly 5. An inclined front frame slide 7 is mounted on the frame 1 between the vertical conveyor mechanism 6 and the seedling-pulling assembly 5. The vertical conveyor mechanism 6 includes a conveyor belt main frame 8 installed perpendicular to the front frame slide 7. A drive shaft 9 and a driven shaft 10 are respectively mounted on both sides of the conveyor belt main frame 8. The drive shaft 9 is driven to rotate by a motor. A vertical annular conveyor belt 11 is sleeved on the outside of the drive shaft 9 and the driven shaft 10. Several weed-pulling toothed plates 12 are installed at intervals on both sides of the vertical annular conveyor belt 11, and several weed-pulling teeth 13 are installed on each weed-pulling toothed plate 12.
[0018] Reinforcing support rods 14 are installed on both sides of the top of the conveyor belt main frame 8 and between it and the frame 1, which can strengthen and fix the top of the conveyor belt main frame 8.
[0019] The bottom of the vertical circular conveyor belt 11 is in sliding contact with the front frame slide 7, which can prevent seedlings from entering the gap between the bottom of the vertical circular conveyor belt 11 and the front frame slide 7.
[0020] Several nylon belt rollers 15 are installed on the bottom side of the frame 1, corresponding to the vertical annular conveyor belt 11 away from the front frame slide 7, which can strengthen the support of the vertical annular conveyor belt 11.
[0021] The grass-removing teeth 13 are connected to the grass-removing tooth plate 12 by detachable screws, which makes it easy to disassemble and replace if the grass-removing teeth 13 are damaged.
[0022] Working principle:
[0023] During operation, the fruit and vines are initially separated by the seedling-removing component 2. The fruit is then picked up by the fruit-removing teeth on the fruit-picking component 3 and removed by the fruit-removing device 4 during rotation. The fallen fruit rolls into the collection bin at the rear. Some of the vines remaining on the fruit-removing device 4 are pushed forward to the front slide plate 7 by the seedling-pulling component 5. After the motor starts, it drives the drive shaft 9 to rotate, which in turn drives the vertical circular conveyor belt 11 to rotate. The vertical circular conveyor belt 11 then drives the grass-pulling teeth 13 on it to rotate, which pushes the vines on the front slide plate 7 to one side and they fall to the ground. Because the vertical circular conveyor belt 11 has a large enough space in front and behind and the grass-pulling teeth 13 are long enough, the grass removal speed is fast and efficient, which can prevent the vines from accumulating and tangling on the front slide plate 7. In addition, the vertical circular conveyor belt 11 can also block the vines, effectively preventing the vines from falling forward onto the protective cover of the seedling-removing component 2, thus achieving the effect of smoothly discharging the vines to one side of the hoist cutting table.
