Description

Technical Field

[0001] The invention relates to the field of tobacco leaf harvesting, and in particular to a tobacco leaf picking device. Background Art

[0002] Tobacco is a key cash crop in my country's national economy. With existing machine harvesting techniques, tobacco leaves often fall through the gaps between the frames or slide off the rear end of the frames. Furthermore, tobacco leaves are relatively wide and brittle, easily breaking and damaging during transport, severely impacting their quality and yield.

[0003] Therefore, it is necessary to provide a new technical solution. Summary of the Invention

[0004] In order to solve the technical problems existing in the prior art, the present invention discloses a tobacco leaf picking device, and the specific technical solution is as follows:

[0005] The present invention provides a tobacco leaf picking device, comprising a fixing frame, a picking mechanism, a crawler wheel, a base frame, a first conveyor belt, a second conveyor belt, a third conveyor belt and a collecting frame.

[0006] The picking mechanism picks the tobacco leaves from the plant, and the first conveyor belt on the base frame sends the tobacco leaves to the side, where they are clamped by the second conveyor belt and the third conveyor belt and transported upward to the top of the fixed frame and then fall into the collection frame.

[0007] Furthermore, the fixing frame is H-shaped, the bottoms of both sides of the fixing frame are respectively connected and fixed to the track wheels, and the bottoms of both sides of the fixing frame extend inward to form fixing seats.

[0008] The picking mechanism is pivotally connected to the lower end of the center of the top of the fixing frame.

[0009] The collecting frames are fixed on both sides of the top of the fixing frame respectively.

[0010] The base frames are respectively fixed on the fixing seats.

[0011] The first conveyor belt is wrapped around the surface of the base frame and conveys the tobacco leaves falling from the picking mechanism to the side of the fixed frame.

[0012] The second conveyor belt is vertically fixed on the side of the fixing frame, and the bottom of the second conveyor belt is close to the outer end of the first conveyor belt.

[0013] The third conveyor belt is vertically fixed on the fixed frame inside the second conveyor belt. The bottom of the third conveyor belt is higher than the bottom of the second conveyor belt, and the top of the third conveyor belt is lower than the top of the second conveyor belt. The gap between the third conveyor belt and the second conveyor belt transports the tobacco leaves upward. After reaching the top, the tobacco leaves pass through the top of the third conveyor belt and fall inward into the collection frame.

[0014] Furthermore, a connection hole is provided on the outer side of the fixing seat, and an arc-shaped hole is provided on the inner side of the fixing seat.

[0015] A first connecting shaft and a second connecting shaft are provided on the side of the base frame. The first connecting shaft passes through the connecting hole and is pivotally connected to the fixing seat. The second connecting shaft is movably arranged in the arc hole. A thread is provided on the second connecting shaft. The second connecting shaft cooperates with a nut to fix the base frame to the fixing seat. The flipping angle of the base frame can be adjusted by adjusting the position of the second connecting shaft in the arc hole.

[0016] Furthermore, a first baffle is provided between the outer end of the first conveyor belt and the bottom of the second conveyor belt. The first baffle is fixed on the fixing frame, and the first baffle forms an angle of 45° with the horizontal direction.

[0017] Furthermore, rollers are pivotally provided at the opposite end portions of the inner sides of the two base frames, and multiple rows of support bars are provided on the rollers. The support bars in each row are spaced apart, and the support bars on the two rollers are staggered with each other. When the rollers rotate, the tobacco leaves in the middle are swept to both sides by the support bars.

[0018] Furthermore, the support strips on the two rollers are elastic, and the ends of the support strips on both sides overlap with each other without leaving any gaps.

[0019] Furthermore, the chassis is provided with a first guide mechanism on the front side in the forward direction, and a second baffle is provided on the rear side in the forward direction.

[0020] The first guide mechanism is in a pointed shape and extends horizontally forward, and the first guide mechanism is close to the inner end of the side of the base frame.

[0021] The second baffles extend vertically upward from the side of the base frame, and the second baffles are respectively close to the inner end of the side of the base frame, and the opposite sides of the two second baffles form a V shape.

[0022] Furthermore, the picking mechanism is provided with a second guide mechanism, which is respectively arranged on both sides of the picking mechanism, and the front ends of the second guide mechanisms form a V-shaped angle with each other, so as to fold the tobacco leaves onto the picking mechanism.

[0023] The present invention has the following beneficial effects:

[0024] 1. The tobacco leaf picking device provided by the present invention has a base frame that can flexibly adjust the angle, thereby flexibly adjusting the gap width between the base frames, and can adapt to the harvesting of tobacco plants of different widths.

[0025] 2. The tobacco leaf picking device provided by the present invention has a roller provided at the inner end of the base frame, and multiple rows of support bars are provided on the roller. The support bars on both sides are staggered and overlapped to prevent tobacco leaves from falling through the gaps in the base frame.

[0026] 3. The tobacco leaf picking device provided by the present invention is provided with a first guide mechanism and a second guide mechanism, which adopt a V-shaped structure to effectively close and collect tobacco leaves to prevent plants from being missed.

[0027] 4. The tobacco leaf picking device provided by the present invention is equipped with a first baffle and a second baffle. The first baffle reduces the right-angle dead angle between the two conveyor belts, not only facilitating the transportation of tobacco leaves but also preventing them from breaking and being damaged. The second baffle not only prevents tobacco leaves from sliding off the rear end of the base frame, but also features a V-shaped structure that facilitates the transportation of tobacco leaves.

[0028] 5. The tobacco leaf picking device provided by the present invention can effectively improve the harvesting quality and yield of tobacco leaves.
