Description

Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, in particular to a tobacco leaf harvesting device. Background Art

[0002] Tobacco leaf harvesting and curing is a crucial process in flue-cured tobacco production, particularly leaf plucking. The quality of the leaves, and thus their quality and sales price, is crucial. Currently, tobacco leaves are generally harvested manually. Tobacco is often cultivated in ridges. When leaves reach maturity, farmers pick and transport them along the aisles between adjacent ridges. During this process, many leaves remain unripe and need to be retained. Furthermore, the narrow aisles make it difficult to use appropriate handling equipment to avoid damaging the remaining leaves. Therefore, the harvested leaves must be manually bundled and carried out of the aisles, which is labor-intensive, time-consuming, and labor-intensive. While there are some automatic tobacco leaf pickers on the market, most are complex and expensive, hindering widespread adoption by tobacco farmers in impoverished areas. Furthermore, automatic tobacco leaf pickers cannot clearly distinguish between mature leaves, resulting in poor quality of the subsequent flue-cured tobacco.

[0003] The Chinese utility model patent (authorization announcement number: CN217336490U authorization announcement number: A portable tobacco leaf picking vehicle) includes wheels arranged symmetrically on the left and right. A vertical rod structure slightly higher than the tobacco plants is connected to the axles of the two wheels through a connecting block. The tops of the two vertical rod structures are connected by a cross bar structure. A front support rod is provided in the center of the cross bar structure, and a balancing roller is provided at the bottom end of the front support rod; and a push rod is provided in the middle section of the cross bar structure and a tobacco leaf collection bag is hung. The utility model has a simple structure and low cost. It can transport tobacco leaves between ridges in tobacco fields without damaging the tobacco leaves, saving a lot of transportation labor, and effectively controlling the quality of tobacco leaf picking in combination with manual labor, thereby ensuring the quality of subsequent flue-cured tobacco and improving the economic benefits of flue-cured tobacco. In addition, the utility model can be assembled into a flatbed cart through vehicle plate accessories and used on flat roads. It has diversified functions, strong practicality and high promotion potential. However, the loading capacity of the tobacco leaf collecting bags is small, and a large number of tobacco leaf collecting bags are needed, which increases the cost of use. At the same time, the tobacco leaf collecting bags need to be transported to the head or tail of the ridge for loading. Due to their small loading capacity, the number of transportation times during each ridge harvesting increases, which reduces the harvesting efficiency. Utility Model Content

[0022] like Figure 1 and 2 The figure shows a tobacco leaf harvesting device, comprising a beam 1, wheels 2 and a support frame. The wheels 2 are mounted at the bottom of the beam 1 through the support frame. There are three wheels 2 distributed in a triangular shape. The central axes of the wheels 2 on both sides of the beam 1 are located above the tobacco plants. Collection boxes 3 are fixed on both sides of the beam 1. A U-shaped chute 4 is provided on the inner wall of the collection box 3. The U-shaped bottom of the chute 4 is perpendicular to the beam 1. The cross section of the chute 4 is T-shaped. The chute 4 is used to install a bundling belt, and the harvested tobacco leaves are bundled through the collection box 3, which increases the loading capacity, reduces the number of transportation times during harvesting per ridge, and improves work efficiency. At the same time, the T-shaped structure of the chute 4 can ensure that the bundling belt is always located in the chute 4 when it is not bundled, so as to keep the bundling position unchanged, thereby avoiding affecting the placement of the tobacco leaves and the subsequent bundling effect. During bundling, the chute 4 is ejected from the bundling belt by deformation and the tobacco leaves are bundled tightly. The structure is simple and easy to use.

[0023] In this embodiment, if Figure 1 As shown, it also includes a pressing plate 5, which is used to press the tobacco leaves in the collection box 3. A number of hooks 6 are fixed on the support frame, and the hooks 6 are used to place idle pressing plates 5. The tobacco leaves in the collection frame are further compressed by the squeezing of the pressing plate 5, thereby further increasing the loading capacity of a single collection frame.

[0024] In this embodiment, if Figure 1 As shown, a seat 7 is fixed on the beam 1 facing the collecting box 3. The seat 7 is away from the wheels 2 on both sides of the beam 1. A parasol 8 is installed behind the seat 7. The operator can sit on the seat 7 to pick tobacco leaves, which reduces the labor intensity of the operator.

[0025] In this embodiment, if Figure 1 As shown, a locking structure is also included, which is used to lock the pressing plate 5 in the collection box 3, freeing hands and facilitating the knotting and fixing of the strapping belt.

[0026] In this embodiment, if Figure 2As shown, the locking structure includes a lock block 9, a spring 10 and a lock hole 11 opened on the inner wall of the collection box 3. The top plate of the pressure plate 5 is fixed with a door-shaped limit frame 12. The frame opening of the limit frame 12 faces the outside of the pressure plate 5. The lock block 9 is used to compress the spring 10 and install it on the bottom of the limit frame 12. A pin 13 is fixed on the lock block 9. The pin 13 is slidably installed in the oblong through hole 14. The pin 13 is square to prevent rotation when sliding. The oblong through hole 14 is opened on the side wall of the limit frame 12. The extension direction of the shaped through hole 14 is parallel to the sliding direction of the locking block 9. The locking end of the locking block 9 is a slope, and the slope faces the bottom of the collection box 3. After pressing the pressure plate 5, the slope of the locking block 9 contacts the inner edge of the box opening of the collection box 3, and the locking block 9 retreats into the limit frame 12. When the pressure plate 5 descends to the point where the locking block 9 is aligned with the locking hole 11, the locking block 9 bounces into the locking hole 11 under the action of the spring 10, automatically locking the pressure plate 5. When unlocking, the locking block 9 can be retreated to the limit frame 12 by the pin 13. The structure is simple and easy to use.

[0027] In this embodiment, if Figure 1 and 2 As shown, a handle 15 is also provided on the pressure plate 5, and positioning columns 16 are fixed to the bottom of the limit frame 12 and the bottom of the locking block 9. The spring 10 is sleeved on the positioning column 16 to prevent the spring 10 from being compressed and deformed and popping out of the limit frame 12, thereby causing the automatic locking of the locking block 9 to fail.

[0028] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
