[0019] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively and carefully below in conjunction with the accompanying drawings and preferred embodiments of the specification, but the protection scope of the present invention is not limited to the following specific embodiments.
[0020] like Figure 1 As shown, the root vegetable harvester of the utility model can adapt to most root vegetables that are harvested by cutting, such as lettuce, leek, green onion, celery, etc. This embodiment takes leek harvesting as an example. The root vegetable harvester of this embodiment includes a walking mechanism, a seedling supporting mechanism, a cutting mechanism, and a conveying mechanism. The walking mechanism includes a vehicle body 1, and a pair of front wheels 2 and rear wheels 3 are respectively installed at the front and rear ends of the vehicle body 1, and a hand push handrail 4 is fixedly installed on the vehicle body 1. The root vegetable harvester of the utility model is pushed forward by a person applying force through the hand push handrail 4.
[0021] In this embodiment, the diameter of the rear wheel 3 is larger than the diameter of the front wheel 2. The rear wheel 3 is designed to be larger than the front wheel 2. On the one hand, the large rear wheel can provide better stability and balance, making the cart easier to control when walking, reducing roll and shaking, and having better passability and resistance, and can easily cope with different terrains, reduce resistance during pushing, and reduce the labor intensity of pushing the cart; on the other hand, the large-diameter tire can better reduce the transmission of ground vibration to the electric leek harvester, providing a smoother driving experience.
[0022] like Figure 2 As shown, a collecting basket 7 is movably installed at the rear side of the vehicle body 1, and the harvested leeks are sent into the collecting basket 7 through a conveying mechanism. The collecting basket 7 and the vehicle body 1 are movably installed, so that the collecting basket 7 is easy to replace.
[0023] like Figure 1 As shown, the seedling supporting mechanism includes a straightening guide plate 5 and a seedling separator 6. The two straightening guide plates 5 are symmetrically installed on the outer side of the front end of the vehicle body 1, and the seedling separators 6 are respectively installed on both sides of the feed port at the front end of the vehicle body 1. The straightening guide plates 5 and the seedling separators 6 can be used to straighten and separate the tilted and fallen leeks and then gather them together, so that they can accurately enter the conveying mechanism, thereby reducing the leek damage rate.
[0024] In this embodiment, two feed ports are provided at the front end of the vehicle body 1, and three seedling separators 6 are provided correspondingly, so that double-row harvesting can be realized, and harvesting can be performed even with a wider row spacing. The seedling separator 6 extends downwardly out of the vehicle body 1, and the cross-sectional width of the seedling separator 6 gradually narrows from the rear end to the front end. The front end of the seedling separator 6 is about 5 cm above the ground, and the cross-sectional shape is an arc. The sideways leek plants are lifted up and straightened under the action of the arc on the seedling separator 6, and are prevented from being damaged during the process of supporting the crops.
[0025] like Figure 3 , Figure 4 As shown, the cutting mechanism includes a cutting disc 14 and a driving motor 15 for driving the cutting disc 14 to rotate. Two cutting discs 14 are provided, which are fixedly installed at the bottom of the vehicle body 1 corresponding to the feed inlet and parallel to the ground. The driving motor 15 is connected to the cutting disc 14 through a transmission device. The double-blade cutting design can cut the leek quickly and effectively, and the harvesting range is doubled while ensuring flexibility and compactness, which can solve the problem of wide row spacing harvesting.
[0026] In this embodiment, the transmission device includes a driven gear 16 fixedly connected to the rotating shaft of the cutting blade 14, the driven gear 16 is meshedly connected with an intermediate gear 17, a first bevel gear 18 is coaxially arranged on the intermediate gear 17, and the first bevel gear 18 is meshedly connected with a second bevel gear 19 connected to the output end of the driving motor 15. In this embodiment, the force is transmitted to the left and right gears through the bevel gears to drive the cutting blade 14 below to rotate for cutting, thereby improving the mechanical efficiency and greatly saving the manufacturing cost compared with the traditional dynamic shaft design.
[0027] like Figure 3 As shown, the conveying mechanism includes a first active belt roller 9, a second active belt roller 10, a driven belt roller 8, a conveyor belt 11 and a transmission motor 12. The first active belt roller 9 and the second active belt roller 10 are both installed horizontally on the vehicle body 1, and the first active belt roller 9 and the second active belt roller 10 are located above the collection basket 7 and arranged up and down. One end of the first active belt roller 9 and the second active belt roller 10 are respectively connected to the transmission motor 12. The driven belt rollers 8 arranged vertically are respectively installed on both sides of the front feed port of the vehicle body 1. A group of conveyor belts 11 are respectively arranged on both sides of the feed port. The front ends of the two groups of conveyor belts 11 are respectively wound around the driven belt rollers 8, the tail end of one group of conveyor belts 11 is wound around the first active belt roller 9, and the tail end of the other group of conveyor belts 11 is wound around the second active belt roller 10. In this embodiment, the conveying mechanism is composed of four conveyor belts 11, one above and one below, forming two torsion clamping conveying devices, which can clamp the leeks to prevent them from scattering during cutting, and can also convey the leeks to the collection basket 7.
[0028] In order to prevent the leeks from being damaged due to the scattered leaves of the plants when entering, the distance between the clamping conveyor belts is set to be adjustable. A plurality of conveyor belt adjusting spacers 13 for adjusting the position of the conveyor belt 11 are installed on the first active belt roller 9 and the second active belt roller 10. The conveyor belt 11 can be adjusted by adjusting the position of the conveyor belt adjusting spacers 13 according to the number of leek plants and the planting row spacing.
[0029] Since the stem and leaf parts of leeks have low compression strength and are relatively weak compared to other crops, the outer layer of the surface of the conveyor belt that contacts the leeks is required to be relatively soft, and the working bottom belt material should have sufficient strength and wear resistance to ensure the stability and reliability of clamping and conveying. Taking the above factors into consideration, in this embodiment, the outer layer of the conveyor belt 11 is covered with a high-density sponge layer with high softness, which can reduce mechanical damage. While applying force to the leek plant, it is also subjected to the reaction force of the leek plant, so that the sponge layer forms a depression, which effectively increases the friction force, and further ensures that the leek plant does not slide during the clamping and conveying process and maintains stable conveying. The inner layer of the conveyor belt 11 uses polyvinyl chloride (PVC) as the bottom belt material.
[0030] With the help of the teachings in the foregoing description and the related drawings, a person skilled in the art will be able to think of many modifications and other embodiments of the present invention. Therefore, it is to be understood that the present invention is not limited to the specific embodiments disclosed, and modifications and other embodiments are considered to be included within the scope of the appended claims. Although specific terms are used herein, they are used only in a general and descriptive sense and not for limitation.
