Description

Technical Field

[0001] This application relates to the field of agricultural machinery technology, and in particular to an integrated machine for removing and collecting tobacco stalks. Background Technology

[0002] Tobacco stalks are the residue left after tobacco harvesting. Statistics show that my country produces over 2 million tons of tobacco stalks annually that require disposal. The quality of tobacco stalk disposal directly impacts the planting of the next crop and the maintenance of soil quality. Tobacco stalks are susceptible to many pests and diseases, making them unsuitable for shredding and returning to the field. The most common disposal method in my country is to remove the stalks entirely from the field, but many areas still rely on manual removal. While some stalk-removing equipment exists, it often lacks functionality or has low overall efficiency, requiring collection devices after removal.

[0003] For example, the patent titled "Tobacco Stalk Cleaning and Recycling Tillage Machine," with document number CN115735445A, describes a stalk-pulling device consisting of a rotating shaft, support frame, and lever. This type of device has a mature technology and application background, and provides a good stalk-pulling experience in actual operation. The drive unit is located above the frame, and the power output from the drive unit to the rotary tillage device, stalk-pulling device, and conveyor belt is all completed via belt transmission, making this drive method more energy-efficient and convenient. While this patent has certain advantages, it lacks a self-unloading device after collecting tobacco stalks. Because the tobacco roots are large, the collection box easily fills up, requiring the entire machine to be stopped and the stalks manually unloaded before continuing. This not only wastes labor costs but also reduces efficiency. Furthermore, the patent lacks a limiting device during transport, failing to guarantee that the tobacco stalks will accurately fall into the collection box. Summary of the Invention

[0004] The purpose of this application is to provide an integrated tobacco stalk removal and collection machine to solve the technical problems of high labor costs and low efficiency caused by manually unloading tobacco stalks from the collection box in the prior art.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] An integrated tobacco stalk removal and collection machine includes a traction frame, a stalk-pulling cutter roller, a conveyor chain, a stalk-throwing roller, and a collection box, all sequentially connected to a frame. Wheel frames are located on both rear sides of the frame, with wheels mounted on them. A bevel gearbox is also mounted on the frame, transmitting power to the stalk-pulling cutter roller, conveyor chain, and stalk-throwing roller. The collection box is characterized by an opening and closing control device located behind the stalk-throwing roller, which triggers the opening and closing of the collection box via power transmitted from the bevel gearbox.

[0007] Furthermore, the frame includes a crossbeam, side plates, and a rear cover plate mounted thereon. The crossbeam is located within the frame on the side closest to the traction frame. The side plates and the rear cover plate are located on both sides of the frame. The bevel gearbox is fixed to the crossbeam. A stalk-pulling cutter roller is located below the bevel gearbox. The bevel gearbox drives a double-chain gearbox via a right power output shaft to transmit power to the stalk-pulling cutter roller.

[0008] Furthermore, the conveyor chain includes a front guide wheel and a rear guide wheel. The front guide wheel is mounted on the inner side of the side plate via a matching guide wheel shaft, and the front guide wheel is connected to the stalk pulling roller. The rear guide wheel is mounted on the inner side of the rear cover plate via a rear guide wheel shaft, and the rear guide wheel is connected to the stalk throwing roller.

[0009] The bevel gearbox drives the first sprocket via the left power output shaft. The first sprocket drives the double transition sprocket via a chain. The double transition sprocket drives the second double sprocket via a chain. The second double sprocket drives the rear guide wheel shaft. The rear guide wheel shaft drives the rear guide wheel, thereby driving the conveyor chain. The frame above the conveyor chain is equipped with collection plates on both sides.

[0010] Furthermore, the second compound sprocket drives the third sprocket via a chain, the third sprocket drives the throwing roller, and the throwing roller drives the throwing roller to transmit power; the transmission ratio between the throwing roller and the rear guide wheel shaft is 1:0.68.

[0011] Furthermore, the opening and closing control device includes a gear shift base plate, a worm gear reducer, a cross coupling, a drive shaft, a small sprocket, a large sprocket, a shift plate, a shift wheel, a rotating pull arm, a long pull plate, a short pull plate, a collection box rotating shaft, opening and closing claws, and a spring; a large sprocket and a shift wheel are installed on one side of the gear shift base plate, and a shift plate is installed on the inner side of the large sprocket coaxially; a rotating pull arm is installed on the other side of the gear shift base plate, and the shift wheel is coaxially installed with the rotating pull arm; long pull plates are pinned to both sides of the rotating pull arm, and two short pull plates are pinned to two short pull plates; one end of the spring is hooked on the gear shift base plate, and the other end is hooked to the end of a short pull plate near the long pull plate; the other ends of the two short pull plates are respectively connected to the collection box rotating shaft; five opening and closing claws are evenly arranged in the vertical direction of the rotating shaft.

[0012] When the worm gear reducer transmits power to the small sprocket through the cross coupling and the drive shaft, the small sprocket transmits power to the large sprocket through the chain, and the large sprocket transmits power to the dial plate. The dial plate moves the dial wheel, and when the dial wheel rotates, the rotating pull arm rotates coaxially. The rotating pull arm pulls the long pull plate and the short pull plate, causing the rotating shaft of the collection box connected to the short pull plate to rotate, thereby controlling the opening and closing claws to open.

[0013] When the lever leaves the dial wheel, the power is lost, and the spring connected to the short pull plate pulls the short pull plate, which in turn resets the rotating pull arm and the rotating shaft of the collection box, and the opening and closing claws close.

[0014] Furthermore, a lower baffle is provided between the rotating shaft of the collection box and the longitudinal beam of the collection box, a top cover is installed on the top of the collection box, and a rear baffle is installed at the rear of the collection box.

[0015] Furthermore, the stalk-pulling cutter roller includes a cutter shaft with three triangular fixing plates evenly arranged on it. A stalk-pulling blade is installed between every two triangular fixing plates. The stalk-pulling cutter roller has three rows of stalk-pulling blades arranged circumferentially, with a total of six blades. A cutter shaft circular plate is provided on the left and right sides of each end of the cutter shaft. The cutter shaft circular plate is connected to two triangular fixing plates on its inner side by angle steel. The cutter shaft is connected to the inner side of the side plate. The bevel gearbox transmits power to the cutter shaft by driving a double-chain gear through the right power output shaft.

[0016] Furthermore, the throwing roller includes a throwing roller shaft, with a central disc sleeved in the middle and side discs on both sides. Multiple throwing roller strips are arranged between the side discs and fixed with a fixed central disc. The throwing roller shaft is located inside the rear cover plate.

[0017] Compared with the prior art, this application has the following beneficial effects:

[0018] This application, through innovative design of the conveyor chain and collection box, can collect the pulled tobacco stalks, improving the overall efficiency of stalk pulling. An opening and closing control device is designed on the collection box, allowing the device to automatically lower the collected tobacco stalks after traveling a certain distance, piling them into a heap and reducing labor costs. Gathering plates are installed on both sides of the conveyor chain, and a stalk-throwing roller is designed at the rear of the conveyor chain, improving collection accuracy and preventing tobacco stalks from being missed. The rotation ratio between the stalk-throwing roller and the rear guide wheel shaft is 1:0.68, which can quickly throw the tobacco stalks on the conveyor chain into the collection box, preventing uneven collection. The L-shaped design of the stalk-throwing roller increases the gripping force when in contact with the tobacco stalks. Attached Figure Description

[0034] The present application will now be described in further detail with reference to the accompanying drawings:

[0035] like Figure 1 — Figure 7 As shown, this application provides an integrated tobacco stalk removal and collection machine, including a traction frame 2, a stalk-pulling cutter roller 9, a conveyor chain 8, a stalk-throwing roller 10, and a collection box 11 connected in sequence on a frame 1. Wheel frames 15 are provided on both rear sides of the frame 1, and traveling wheels 16 are installed on the wheel frames 15. A bevel gearbox 7 is also provided on the frame 1. The bevel gearbox 7 is used to transmit power to the stalk-pulling cutter roller 9, the conveyor chain 8, and the stalk-throwing roller 10. An opening and closing control device is provided on the collection box 11. The opening and closing control device is located behind the stalk-throwing roller 10. The opening and closing control device triggers the opening and closing of the collection box 11 through the power transmitted by the bevel gearbox 7.

[0036] Furthermore, the frame 1 includes a crossbeam 4, side plates 5, and a rear cover plate 6 mounted thereon. The crossbeam 4 is located inside the frame 1 on the side closest to the traction frame 2. The side plates 5 and the rear cover plate 6 are located on both sides of the frame 1. The bevel gearbox 7 is fixed on the crossbeam 4. A stalk-pulling cutter roller 9 is located below the bevel gearbox 7. The bevel gearbox 7 drives the double-chain gear 24 through the right power output shaft 36 to transmit power to the stalk-pulling cutter roller 9, causing the stalk-pulling cutter roller 9 to rotate. Specifically, the stalk-pulling cutter roller 9 includes a cutter shaft 901, on which three triangular fixing plates 902 are evenly arranged. A stalk-pulling blade 903 is installed between every two triangular fixing plates 902. The stalk-pulling cutter roller 9 has three rows of stalk-pulling blades 903 arranged circumferentially, with two blades in each row, for a total of six blades 903. A cutter shaft circular plate 904 is located on the left and right sides of each end of the cutter shaft 901. The cutter shaft circular plate 904 is connected to the two triangular fixing plates 902 on its inner side via angle steel 905. The cutter shaft 901 is connected to the frame 1, and the bevel gearbox 7 transmits power to the cutter shaft 901. The circumferential arrangement of the stalk-pulling blades 903 on the stalk-pulling cutter roller 9 is designed to pull the tobacco stalks from the ground and remove any remaining soil from the roots before feeding the tobacco stalks onto the conveyor chain 8.

[0037] Furthermore, the conveyor chain 8 includes a front guide wheel and a rear guide wheel. The front guide wheel is set inside the side plate 5 through an adapter guide wheel shaft, and the front guide wheel is connected to the stalk pulling roller 9. The rear guide wheel 20 is set inside the rear cover plate 6 through a rear guide wheel shaft 19, and the rear guide wheel 20 is connected to the stalk throwing roller 10.

[0038] The bevel gearbox 7 drives the first sprocket 37 via the left power output shaft 35. The first sprocket 37 drives the compound transition sprocket 38 via a chain. The compound transition sprocket 38 drives the second compound sprocket 39 via a chain. The second compound sprocket 39 drives the rear guide wheel shaft 19. The rear guide wheel shaft 19 drives the rear guide wheel 20, thereby driving the conveyor chain 8 and transmitting power to the conveyor chain 8. The frame 1 above the conveyor chain 8 is provided with collection plates 18 on both sides.

[0039] Furthermore, the second compound sprocket 39 drives the third sprocket 40 via a chain, and the third sprocket 40 drives the throwing roller 101, thereby transmitting power to the throwing roller 10. The transmission ratio between the throwing roller 101 and the rear guide wheel shaft 19 is 1:0.68, which ensures that the tobacco stalks are quickly thrown into the collection box 11 when they are conveyed to the throwing roller 10. Specifically, the throwing roller 10 includes a throwing roller 101, with a central disc 102 sleeved in the middle and side discs 103 on both sides. Multiple throwing roller strips 104 are arranged between the side discs 103 and fixed with the central disc 102. The throwing roller 101 is located inside the rear cover plate 6. The throwing roller strips 104 are L-shaped, which can better grip the tobacco stalks.

[0040] Furthermore, the opening and closing control device includes a gear shift plate 21, a worm gear reducer 22, a cross coupling 23, a drive shaft 43, a small sprocket 25, a large sprocket 26, a shift plate 27, a shift wheel 28, a rotating pull arm 29, a long pull plate 30, a short pull plate 31, a collection box rotating shaft 32, an opening and closing claw 33, and a spring 34; the large sprocket 26 and the shift wheel 28 are installed on one side of the gear shift plate 21, and the shift plate 27 is installed coaxially inside the large sprocket 26; the rotating pull arm 29 is installed on the other side of the gear shift plate 21, the shift wheel 28 is coaxially installed with the rotating pull arm 29, and the two sides of the rotating pull arm 29 are respectively pin-connected to the long pull plate 30, and the two long pull plates 30 are pin-connected to the two short pull plates 31, such as... Figure 7 As shown, one end of the spring 34 is hooked on the gear shift seat plate 21, and the other end is hooked on a short pull plate 31 near the end of the long pull plate 30. The other ends of the two short pull plates 31 are respectively connected to the rotating shaft 32 of the collection box. Five opening and closing claws 33 are evenly arranged in the vertical direction of the rotating shaft 32.

[0041] Furthermore, the other end of the rear guide wheel shaft 19 is connected to the worm gear reducer 22 of the opening and closing control device. When the worm gear reducer 22 transmits power to the small sprocket 25 through the cross coupling 23 and the drive shaft 43, the small sprocket 25 transmits power to the large sprocket 26 through the chain, and the large sprocket 26 transmits power to the dial plate 27. The dial plate 27 moves the dial wheel 28. When the dial wheel 28 rotates, the rotating pull arm 29 rotates coaxially. The rotating pull arm 29 pulls the long pull plate 30 and the short pull plate 31 to make the collection box rotating shaft 32 connected to the short pull plate 31 rotate, thereby controlling the opening and closing claw 33 to open.

[0042] When the dial plate 27 leaves the dial wheel 28, the power is lost, and the spring 34 connected to the short pull plate 31 pulls the short pull plate 31, thereby causing the rotating pull arm 29 and the collection box rotating shaft 32 to reset, and the opening and closing claw 33 to close.

[0043] Furthermore, a lower baffle 42 is provided between the rotating shaft 32 of the collection box and the longitudinal beam of the collection box, a top cover 13 is installed on the top of the collection box, and a rear baffle 14 is installed at the rear of the collection box.

[0044] The working process of this application:

[0045] During use, the traction frame 2 is installed with the external traction vehicle, and the bevel gearbox 7 is connected to the power source of the external traction vehicle. The right power output shaft 36 of the bevel gearbox 7 transmits power to the lower stalk pulling roller 9 through the double chain gear 24. The stalk pulling roller 9 begins to rotate. The left power output shaft 35 of the bevel gearbox 7 drives the first sprocket 37 to rotate. The first sprocket 37 drives the double transition sprocket 38 to rotate through the chain. The double transition sprocket 38 drives the second double sprocket 39 to rotate through the chain. The second double sprocket 39 drives the conveyor chain 8 to rotate, and the conveyor chain 8 begins to work. At the same time, one gear of the second double sprocket 39 drives the third sprocket 40 to rotate through the chain. The third sprocket 40 is installed on the throwing roller 101, and the throwing roller 10 begins to rotate. A worm gear reducer 22 is installed on the right side of the rear guide wheel shaft 19. The worm gear reducer 22 is connected to the ten-speed transmission shaft 43 and the ten-speed transmission shaft 101 to the worm gear reducer 101. The coupling 23 transmits power to the small sprocket 25 of the collection box. The small sprocket 25 transmits power to the large sprocket 26 via a chain. The large sprocket 26 drives the dial plate 27 to rotate. After the dial plate 27 rotates one revolution, it drives the dial wheel 28 to rotate through a certain angle and then moves away to enter the next cycle. The dial wheel 28 drives the rotating pull arm 29 to rotate through a certain angle. During the rotation of the rotating pull arm 29, it pulls the long pull plate 30 and the short pull plate 31 connected to it, which in turn causes the collection box rotating shaft 32 connected to the long pull plate 30 and the short pull plate 31 to rotate. The collection box rotating shaft 32 drives the five opening and closing claws 33 to open outward. This process releases the collected tobacco stalks. When the dial plate 27 leaves the dial wheel 28, the power is lost. The spring 34 connected to the short pull plate pulls the short pull plate 31, which in turn causes the rotating pull arm 29 and the collection box rotating shaft 32 to reset. The opening and closing claws 33 close, and the collection work continues.

[0046] In general, under the power output of the tractor, the stalk pulling roller 9, the conveyor chain 8, and the stalk throwing roller 10 start to rotate simultaneously. The tractor moves forward, driving the stalk pulling roller 9 to penetrate deep into the soil. By rotating, the tobacco stalk is pulled out. The pulled-out tobacco stalk will fall on the conveyor chain 8 and be conveyed upward to the stalk throwing roller 10. The stalk throwing roller 10 rotates quickly and throws the tobacco stalk onto the rear baffle 14 of the collection box behind it, and then it falls onto the opening and closing claw 33. After collecting for a period of time, the deflector plate 27 deflects the deflector wheel 28, causing the opening and closing claw 33 to open and discharge the collected tobacco stalk. After the deflector plate 27 leaves the deflector wheel 28, the opening and closing claw 33 closes under the tension of the spring (34) and enters the next round of collection.

[0047] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
