Technical Field
[0001] This utility model relates to the field of tobacco leaf harvesting technology, specifically a foldable single-wheel harvesting vehicle for tobacco leaves in the field. Background Technology
[0002] Currently, in the hilly areas of southern China, due to the abundance of mountains and scarcity of flat land, large agricultural machinery cannot be deployed, resulting in a lack of mechanized tobacco production, especially tobacco harvesting, which still relies heavily on manual labor. With an aging population, the labor force for tobacco production is increasingly scarce. A useful way to address this labor shortage is to use agricultural machinery to replace or assist manual labor. However, some harvesting machinery currently available on the market is too large to effectively navigate between fields.
[0003] In the prior art, Chinese utility model application number CN202221670822.7 discloses a tobacco harvesting cart, including a frame, a pusher frame installed on one side of the frame, a set of wheels installed at the bottom of the frame, a controller, an alarm, a weighing module, a power supply device for supplying power to electrical components, and a hopper installed on the weighing module; the weighing module and the alarm are both electrically connected to the controller; the weighing module is used to weigh the net weight of the tobacco leaves in the hopper; the weighing module is located on the top surface of the frame. By weighing the net weight of the harvested tobacco leaves through the weighing module, when the rated harvest amount is reached, the alarm reminds the workers to stop harvesting, realizing quantitative harvesting of tobacco leaves by the tobacco harvesting cart. When all tobacco harvesting carts have achieved quantitative harvesting, the total total amount of tobacco leaves harvested will conform to the rated total amount of tobacco leaves harvested, without being too much or too little, making the tobacco harvesting more accurate.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1-5 This utility model provides a technical solution: a foldable single-wheel harvester for tobacco leaves in the field, including a frame 10, an adjustable handlebar 20, a bucket 30, two sets of limiting components 50 and solid tires 60, all mounted on the frame 10. The adjustable handlebar 20 is located at one end of the frame 10, the two sets of limiting components 50 are symmetrically arranged at both ends of the frame 10, the bucket 30 is located above the frame 10, and two sets of support frames 40 are rotatably mounted on the bucket 30 and engaged with the limiting components 50.
[0027] In addition, such as Figure 3 As shown, the frame 10 includes a support frame beam 101. One end of the support frame beam 101 is fixedly connected to an extension square tube 102 for inserting two sets of insertion rods 204. One end of the upper surface of each set of extension square tubes 102 is provided with a mounting hole 103. A locking bolt 104 is provided in the mounting hole 103 and inserted into the positioning hole 205. By screwing the locking bolt 104 into the positioning hole 205 at different positions, the stability of the connection between the adjustable handlebar 20 and the frame 10 is improved.
[0028] It is worth noting that, such as Figure 3 As shown, two sets of wheel frames 105 are fixedly connected to one end of the lower surface of the support frame beam 101. The lower end of each set of wheel frames 105 is provided with a positioning sleeve 106 for the solid tire 60 to be rotated and installed. The wheel frame 105 is arranged in a triangular shape. The positioning sleeve 106 facilitates the installation of the solid tire 60 and the solid tire 60 has a long service life.
[0029] Furthermore, such as Figure 3 As shown, two sets of support legs 107 are fixedly connected to the other end of the lower surface of the support frame beam 101. The upper extension lines of the two sets of support legs 107 intersect each other. The support legs 107 are set in a triangular frame. The stability of the harvesting vehicle when it is stationary can be ensured by the inclined support legs 107.
[0030] Preferred, such as Figure 5 As shown, the limiting component 50 includes a fixing block 501 fixedly connected to the support frame beam 101. The upper surface of the fixing block 501 is fixedly connected to a lower clamping seat 502 for clamping the support frame 40. The lower clamping seat 502 facilitates the positioning of the unfolded support frame 40, thereby ensuring the unfolding stability of the truck bed 30 and preventing the truck bed 30 from folding when collecting tobacco leaves.
[0031] It is worth noting that, such as Figure 5 As shown, a wing screw 503 is threadedly connected to one side of the fixing block 501. A connecting plate 504 is rotatably mounted on the wing screw 503. Two sets of guide rods 506, which are inserted into one side of the fixing block 501, are fixedly connected to one side of the connecting plate 504. A limiting plate 505, which prevents the support frame 40 from disengaging from the lower bracket 502, is fixedly connected to the upper surface of the connecting plate 504. The wing screw 503 facilitates the adjustment of the position of the connecting plate 504, thereby facilitating the adjustment of the position of the limiting plate 505. The limiting plate 505 is L-shaped and can be moved above the lower bracket 502, thereby preventing the support frame 40 from disengaging from the lower bracket 502.
[0032] like Figure 4 As shown, the truck bed 30 mainly consists of a bottom bucket 301, a folding collar 302, and a support bucket 303. The folding collar 302 is fixedly connected to the lower end of the support bucket 303, and the lower end of the folding collar 302 is fixedly connected to the upper end of the bottom bucket 301. The cross-sections of the bottom bucket 301, the folding collar 302, and the support bucket 303 are all trapezoidal. The folding collar 302 allows the support bucket 303 to be fitted onto the outside of the bottom bucket 301, thus facilitating the folding and storage of the truck bed 30 and reducing the volume of the harvesting vehicle.
[0033] In this embodiment, as Figure 4 As shown, the folding collar 302 is mainly made of a lower folding layer 3021 and an upper folding layer 3022 integrally formed. The lower opening section of the lower folding layer 3021 is smaller than the upper opening section of the upper folding layer 3022. By folding the upper folding layer 3022 and the lower folding layer 3021, the upper folding layer 3022 is located outside the lower folding layer 3021, which facilitates the folding and storage of the truck bed 30. Both the upper folding layer 3022 and the lower folding layer 3021 are made of rubber.
[0034] In a further preferred embodiment, such as Figure 4 As shown, the upper opening of the support bucket 303 is integrally formed with a reinforcing ring 304. Two sets of upper clamping seats 305 are symmetrically arranged on the lower surface of the reinforcing ring 304 to clamp the support frame 40. Two sets of hinge seats 306 are symmetrically arranged on the lower surface of the reinforcing ring 304 to allow the support frame 40 to rotate. The reinforcing ring 304 improves the strength of the opening of the support bucket 303, thereby improving the service life of the support bucket 303. The upper clamping seats 305 facilitate the positioning of the stored support frame 40 and prevent the stored support frame 40 from shaking.
[0035] Furthermore, such as Figure 3As shown, the adjustable handlebar 20 includes a connecting beam 201 and irregular handles 202 fixedly connected to both ends of the connecting beam 201. One end of each of the two sets of irregular handles 202 is provided with an anti-slip rubber sleeve 203. The anti-slip rubber sleeve 203 is used to prevent the harvester from slipping their hand when pushing the harvesting vehicle, thereby ensuring the stability of pushing the harvesting vehicle.
[0036] Preferred, such as Figure 3 As shown, each of the two sets of irregularly shaped handles 202 has a rod 204 welded to one end relative to the anti-slip rubber sleeve 203. The upper surface of the rod 204 has multiple positioning holes 205. The rod 204 is cuboid in shape and can be easily inserted into the extension square tube 102. By varying the insertion depth, different lifting forces are applied to the harvesting vehicle, thereby allowing the position of the adjustable handle 20 to be adjusted according to the amount of tobacco leaves in the truck bed 30, saving physical effort.
[0037] In use, the support frame 40 flips within the hinge seat 306 and locks into the upper seat 305, thereby applying pressure to the reinforced bucket. This causes the upper folding layer 3022 to flip onto the outside of the lower folding layer 3021, thus moving the reinforced bucket from above the bottom bucket 301 to the outside of the bottom bucket 301. This facilitates the folding and storage of the bucket 30, improving the folding and storage of the collection vehicle. Conversely, it facilitates the collection of tobacco leaves after the bucket 30 is unfolded. The position of the limiting plate 505 is adjusted using the butterfly screw 503, limiting the support frame 40 locked in the lower seat 502 and preventing the support frame 40 from detaching from the lower seat 502. This improves the stability of the bucket 30 when unfolded. By adjusting the distance between the adjustable platform and the frame 10, the force required to lift and lower the bucket 30 can be saved, thereby reducing the labor intensity of the harvesting personnel.
